专利说明:

[0001] [001] The present invention relates to a tip finishing element configured to cut the tip ends of the spot welding electrode tips. Fundamental Technique
[0002] [002] In automobile production lines, a local welding technique has often been used to assemble the body of a car. According to the local welding technique, however, as the welding work is carried out repeatedly, an increasingly thick oxide film is gradually deposited on the tip ends of the electrode tips. If the welding process is carried out without any finishing work being carried out on these thick tips, then the quality of the resulting welded parts will deteriorate. For this reason, such thick-tipped ends of the electrode tips need to be cut regularly by a tip-finishing element to remove the oxide film.
[0003] [003] Meanwhile, the pieces that are removed while the electrode tips are being cut by the tip finishing element can spread and deposit in a drive unit or any other part of another machine. In this case, the load on the drive unit decreases, and in the worst case, it increases so much that it causes the machine to break. Thus, to avoid such an unwanted situation, a part of the tip finishing element that performs the cutting work is enclosed in a cover wrap to prevent such pieces from spreading to the environment.
[0004] [004] For example, the tip finishing element described in patent document 1 includes a rotary cutter, from which the geometric axis of rotation extends vertically. The upper and lower surfaces of the rotary cutter are respectively provided with a pair of recessed receivers that receive the tip ends of the electrode tips so that the central axis of the electrode tips agrees with the axis of rotation of the rotary cutter. The tip finish element is configured to cut the respective tip ends of the electrode tips with a pair of cutting edges provided for the rotary cutter by rotating the rotary cutter with the tip ends of the pair of electrode tips, which are arranged to face each other on both sides of the rotary cutter in the direction of the geometric axis of rotation, received in these receivers with recess. In addition, a pair of cover wraps covering, respectively, the upper and lower surfaces of the rotary cutter are respectively arranged on and under the rotary cutter in order to prevent the scraped parts through the cutting work with the rotary cutter from spreading. Citation List Patent Document
[0005] [005] Patent document 1: Japanese unexamined patent publication No. 2004-202504 Summary of the Invention Technical problem
[0006] [006] In fact, the arrangement of such cover wraps over and under the rotary cutter as in patent document 1 reliably prevents the pieces removed through cutting work on the electrode tips from spreading. In this case, however, the size of the tip finishing element increases in the direction of the geometric axis of rotation.
[0007] [007] In view of the above grounds, it is, therefore, an objective of the present invention to allow a tip finishing element with the ability to simultaneously cut the respective tip ends of a pair of electrode tips that are arranged to be facing each to the other has a compact structure that successfully prevents the parts removed through cutting work from spreading. Solution of the problem
[0008] [008] To achieve this object, according to the present invention, the open end of one of the two recessed receivers is covered with a cover wrap, and a cover plate is fixed to a rotary cutter in order to cover the open end of the other recessed receiver.
[0009] [009] Specifically, a first aspect of the present invention is a tip finishing element including: a rotary cutter configured to simultaneously cut the respective tip ends of a pair of local welding electrode tips arranged to face each other on both sides in the direction of its geometric axis of rotation by rotating a pair of cutting edges that are provided for the respective tip ends; and a cover wrap configured to prevent the parts removed by cutting work with the rotary cutter from spreading. The rotary cutter includes: a pair of recessed receivers arranged symmetrically in the direction of the axis of rotation to receive the respective tip ends of the electrode tips so that the central axis of the electrode tips agree with the axis of rotation while the receivers are cutting the respective tip ends of the electrode tips; and a hollow part running in the direction of the geometric axis of rotation to provide an opening that communicates with the respective recessed receivers. The cover wrap is provided to cover one side of the rotary cutter that has one of the pair of recessed receivers, and has an opening associated with a recessed receiver. A cover plate having, in its central part, an insertion hole for the electrode tip, of which the shape corresponds to the profile of the electrode tips, is fixed to the other side of the rotary cutter that has the other receiver with recess in order to cover the other receiver with recess.
[0010] [010] A second aspect of the present invention is an embodiment of the first aspect of the present invention. In the second aspect, an air discharge device for discharging compressed air towards a surface of the cover plate is disposed near the other side of the cover plate opposite the rotary cutter, and a plurality of air inlet holes are cut on the side. side through the cover plate in such positions so that they are facing the cutting edge in a direction in which the rotary cutter rotates.
[0011] [011] A third aspect of the present invention is an embodiment of the second aspect of the present invention. In the third aspect, the air inlet holes form cuts that extend radially from the geometric axis of rotation of the rotary cutter.
[0012] [012] A fourth aspect of the present invention is an embodiment of any of the first to third aspects of the present invention. In the fourth aspect, an air suction device for sucking air from within the cover wrap and a compressed air delivery device for introducing compressed air into the cover wrap are connected to the cover wrap. The compressed air delivery device and the air suction device are spaced apart so that the rotary cutter's geometric axis of rotation is located between the two devices. Advantages of the Invention
[0013] [013] According to the first aspect of the present invention, if the rotary cutter is rotated with an electrode tip inserted through an opening and received in a recessed receiver and with the other electrode tip inserted through the insertion hole of electrode tip and received at the other recessed receiver, the tip ends of these electrode tips are cut by the respective cutting edges provided for the recessed receivers. Then, the parts removed by the tip of the electrode will fly through the open end of the recessed receiver and enter the cover wrap, and therefore are prevented from spreading. In the meantime, the parts removed by the other electrode tip will attempt to fly through the open end of the other recessed receiver, but, in fact, will collide with and bounce off the cover plate and then enter the cover wrap through the passage through the hollow part. In this way, all other parts removed by cutting the electrode tips will be able to enter the cover wrap, and will be reliably prevented from spreading. In addition, unlike patent document 1, there is no need to provide cover wraps on both sides of the rotary cutter in the direction of the axis of rotation, which in this way makes the finishing element compact in its direction of geometric axis of rotation.
[0014] [014] According to the second aspect of the present invention, the compressed air discharged by the air discharge device is blown against the cutting edges through the air inlet holes of the cover plate, thereby shaking the parts outwards. cutting edges and preventing the parts from disturbing the cutting work of the tip ends of the electrode tips.
[0015] [015] In accordance with the third aspect of the present invention, the air inlet holes have an elongated shape, which in this way prevent the parts removed during the cutting of the electrode tips from suddenly passing through the air inlet holes. and spread around the tip finish.
[0016] [016] In accordance with the fourth aspect of the present invention, the parts accumulated in the vicinity of the air suction device inside the cover wrap are evacuated from the cover wrap with the air suction device sucking air from inside the cover wrap. roof. Meanwhile, the parts accumulated in the vicinity of the compressed air delivery device inside the cover wrap are caused by a turbulent air flow, produced by the compressed air introduced by the compressed air delivery device, to float and travel in the direction of the device. air suction. After that, the parts are evacuated by the air suction device from the cover wrap. In this way, all parts removed from inside the cover wrap are reliably evacuated from the cover wrap.

[0021] [021] The modalities of the present invention will now be described with reference to the attached drawings. Note that the following description of the preferred embodiments is merely an example in nature.
[0022] [022] Figure 1 illustrates a tip finishing element 1 according to an embodiment of the present invention. This tip finishing element 1 is configured to simultaneously cut the tip ends 10a of a pair of local welding electrode tips 10 (see figure 4) that are fitted to the ends of a G1 rod of a welding gun (not shown) ) so that they are facing each other. This tip finishing element 1 includes a body wrap 2 surrounding the primary parts of the tip finishing element 1, and a cover wrap 3 configured to prevent the parts removed during the cutting process from spreading.
[0023] [023] The body wrap 2 includes a motor housing part 2a which has a generally circular cylindrical shape extending vertically and which houses a drive motor (not shown) inside and a projected plate-type rectangular part 2b which protrudes horizontally from a region of the motor housing part 2a near the top.
[0024] [024] As shown in figure 2, an upper hollow hole 2c and a lower hollow hole 2d are respectively cut through the upper and lower surfaces of a generally central region of the projected plate-like part 2b.
[0025] [025] Within the projected part type plate 2b and between the top and bottom holes 2c and 2d, an output gear type ring 4 is rotatably fixed on a vertical axis of rotation of vertical extension C1 through a pair (this ie, upper and lower) of Be1 supports. Output gear 4 is configured to be rotated on the C1 axis of rotation by a drive motor and a gear hitch mechanism (none of which is illustrated).
[0026] [026] Within the output gear 4, a rotary cutter 5 is removably fixed with a Sc1 screw.
[0027] [027] As illustrated in figure 3, the rotary cutter 5 includes a metal retainer 51 which forms a generally C shape with a wide width in a flat view and which also defines a vertically short columnar shape.
[0028] [028] Retainer 51 has, on one side in the longitudinal direction, a recess with notches 52 that is not only opened laterally and outwards, but also extends vertically to be opened both upwards and downwards. The notch recess 52 has a fan shape generally notched in a flat view.
[0029] [029] In addition, the upper and lower surfaces of retainer 51 have respectively a pair of receivers with recess 53, of which the diameter gradually decreases towards the middle part of retainer 51. These receivers with recess 53 are symmetrical to each other in the direction of the geometric axis of rotation.
[0030] [030] Each of the recessed receivers 53 has a shape corresponding to the curved shape of the tip ends 10a of the electrode tips 10, and is configured to receive the tip end 10a of an associated tip within the electrode tips 10, and it is configured to receive the tip end 10a of an associated tip among the electrode tips 10 in a state in which the central axis of the electrode tip 10 agrees with the axis of rotation C1.
[0031] [031] At the top and bottom edges of retainer 51, on one side in the longitudinal direction, respectively defined are the upper and lower pendant parts 54 and 55 that hang outwards and laterally.
[0032] [032] On the other hand, the upper and lower edges of retainer 51 on the other side in the longitudinal direction, respectively, the upper and lower protuberances 56 and 57 are defined, which not only project outwards and to the side, but also extend horizontally ( that is, in a direction that forms an intersection with the longitudinal direction of the retainer 51). A semicircular recess 56a that is opened outwards and to the side has been cut through the middle of the upper protuberance 56.
[0033] [033] A part to be surrounded with the inner peripheral surface of the outlet gear 4 and the notched recess 52 when the rotary cutter 5 is fitted to the outlet gear 4 constitutes a hollow part 50 according to the present invention. The hollow part 50 runs through the direction of the geometric axis of rotation and provides an opening that communicates with the respective recessed receivers 53.
[0034] [034] An internal side surface of the notched recess 52 is provided with a mounting surface 58 that runs in the longitudinal direction of the retainer 51. The mounting surface 58 has a generally triangular shape in a side view.
[0035] [035] Attached to the mounting surface 58, a generally triangular metal cutting plate 6, which is used to cut the tip ends 10a of the electrode tips 10, and a metal breaker type Br1 ring with a tapered outer peripheral surface, using an SC2 screw.
[0036] [036] The top and bottom edges of the cutting board 6 define a pair of cutting edges 6a. When the cutting board 6 is mounted on the mounting surface 58, the respective cutting edges 6a have a curved shape corresponding to that of the respective recessed receivers 53.
[0037] [037] Through the receiver with the upper recess 53 of the rotary cutter 5, a disc-type cover plate 7 is fixed in order to cover the open end of the receiver with the upper recess 53.
[0038] [038] An electrode tip insertion hole 7a, of which the shape corresponds to the profile of the electrode tips 10, is cut through an intermediate part of the cover plate 7.
[0039] [039] In addition, a plurality of air inlet holes 7b are cut side by side through the cover plate 7 in such positions so that they face the cutting edge 6a in the direction of rotation of the rotary cutter 5. The respective air inlet holes 7b form cuts extending radially from the geometric axis of rotation C1 of the rotary cutter 5.
[0040] [040] Through the cover plate 7 (that is, through the surface of the cover plate 7 opposite the rotary cutter 5), disposed close by, there is an air discharge unit 11 (which is an implementation of the air discharge e) that discharges the compressed air towards the surface of the cover plate 7.
[0041] [041] The air discharge unit 11 includes a discharge nozzle generally in the shape of a pen 11a that discharges the compressed air, a first air tube 11b that guides the compressed air to the discharge nozzle 11a, and a solenoid valve in box shape 11c which is connected to an intermediate point in the first air tube 11b to control the discharge of compressed air through the discharge nozzle 11a. The tip end of the discharge nozzle 11a is arranged in such a position that it faces an external peripheral part of the surface of the cover plate 7.
[0042] [042] The cover wrap 3 has a plate shape that extends horizontally in order to intersect the direction in which the plate-like protrusion part 2b protrudes. A longitudinal end of the cover wrap 3 forms an inverted V shape in a plan view.
[0043] [043] A communication hole 3a that communicates with the inner space of the cover wrap 3 is cut through the top surface of the cover wrap 3. The cover wrap 3 is attached to the bottom surface of the projection part like plate 2b of so that the communication hole 3a faces the receiver with lower recess 53. That is, cover wrap 3 is provided to cover the receiver with lower recess 53 of the rotary cutter 5. As can be seen, the finishing element of tip 1 according to this modality of the present invention has its size reduced in the direction of its geometric axis of rotation, since, unlike patent document 1, there is no need to provide cover wraps 3 on both sides of the rotary cutter 5 in the direction of its geometric axis of rotation.
[0044] [044] The bottom surface of the cover wrap 3 and a side surface away from the motor housing part 2a are provided with a wide continuous notch 3b (opening) that extends horizontally so as to intersect the longitudinal direction of the cover wrap. cover 3. The notch 3b is associated with the receiver with lower recess 53.
[0045] [045] The notch 3b is covered with a pair of cover brushes 8 which are arranged side by side in the longitudinal direction of the cover wrap 3.
[0046] [046] Each of the cover brushes 8 includes a base element 81 that runs along a side edge portion of the notch 3b and a bundle of resin bristles 82 that are transplanted into the base element 81. The two bundles of bristles 82 of the respective base elements 81 extend in the longitudinal direction of the cover wrap 3 to reach an almost central part of the notch 3b and, eventually, to cover the notch 3b.
[0047] [047] The respective bundles of bristles 82 are configured to bend up and close to the space between the lateral edges of the notch 3b and the outer periphery of the electrode tip 10 as illustrated in figure 4 when the electrode tip 10 is inserted from bottom, and passed through the notch 3b.
[0048] [048] A first mounting hole 3c that communicates with the internal space is cut through the bottom surface of the cover wrap 3 at one end of the longitudinal direction. An air suction tool 9 (air suction device) for sucking air from inside the cover wrap 3 is connected to the first mounting hole 3c.
[0049] [049] The air suction tool 9 includes a generally cylindrical tool body 91 that extends vertically. The outer peripheral surface of an upper half of the tool body 91 projects outwardly with respect to the outer peripheral surface of a lower half.
[0050] [050] A groove with a ring-shaped recess that runs around the central geometric axis of the cylinder is provided midway on the inner peripheral surface of the tool body 91. The rest of the inner peripheral surface of the tool body 91 under the groove with a ring-shaped recess, it has an inverted tapered shape, from which the diameter gradually increases downwards.
[0051] [051] A generally annular suction unit 92 is fitted into the groove with an annular recess. Within the suction unit 92, an annular air passage 92a is defined, from which the width gradually decreases downwards.
[0052] [052] When compressed air is introduced into an upper part of the air passage 92a using an air compressor (not shown), the compressed air is discharged through the air passage 92a into a lower part of the space within the body tool 91. As a result, the upper part of the space within the tool body 91 exhibits a negative pressure. Consequently, air is sucked in from the cover casing 3 through the upper part of the tool body 91 and then evacuated through the lower part of the tool body 91.
[0053] [053] The upper surface of the cover wrap 3 at the other end in the longitudinal direction is provided with a second 3d mounting hole that communicates with the internal space.
[0054] [054] One end of a second air tube 93 for introducing compressed air into the space within the cover wrap 3 (i.e., compressed air delivery device) is connected to the second mounting hole 3d. That end of the second air tube 93 and the air suction tool 9 are spaced from each other so that the axis of rotation C1 of the rotary cutter 5 is located between them.
[0055] [055] Meanwhile, the other end of the second air tube 93 is connected to an intermediate point on the first air tube 11b so that some of the compressed air discharged out of the air discharge unit 11 is introduced into the space inside the cover wrap 3.
[0056] [056] Subsequently, with the rotary cutter 5 rotated around the axis of rotation C1, a pair of electrode tips 10 is arranged so that the tips are facing each other so as to vertically insert the projected plate-like part 2b and the cover wrap 3 between them (that is, on both sides in the direction of the geometric axis of rotation) and are close to each other. Then, as illustrated in figure 4, the tip end 10a of the upper electrode tip 10 passes through the electrode tip insertion hole 7a and is received by the receiver with upper recess 53 and cut by the upper cutting edge 6a. On the other hand, the tip end 10a of the lower electrode tip 10 passes through the respective bundles of bristles 82 of the cover brushes 8, passes through the notch 3b and the communication hole 3a, and is received by the receiver with lower recess 53 and cut by the lower cutting edge 6a.
[0057] [057] Next, it will be described how to carry out the work of cutting the tip ends 10a of the electrode tips 10 with the finishing element 1.
[0058] [058] Firstly, by driving a drive motor (not shown) of the finishing element 1 in rotation, the output gear 4 is rotated, thus rotating the rotary cutter 5 on the axis of rotation C1 .
[0059] [059] In addition, compressed air is supplied to the air suction tool 9 and the air discharge unit 11 using an air compressor (not shown). In this way, the air inside the cover wrap 3 is sucked by the air suction tool 9 and evacuated from the cover wrap 3. In the meantime, compressed air is also discharged through the discharge nozzle 11a to the surface of the cover plate 7, and is introduced into the space within the cover wrap 3 through the second air tube 93.
[0060] [060] Next, the two electrode tips 10 vertically facing each other are moved over the projected plate-like part 2b and under the cover wrap 3, respectively, and the central geometric axis of the respective electrode tips 10 is aligned with the axis of rotation C1 of the rotary cutter 5.
[0061] [061] After that, the two electrode tips 10 are brought together. Then, as illustrated in figure 4, the upper electrode tip 10 passes through the electrode tip insertion hole 7a of the cover plate 7 and is received by the receiver with the upper recess 53, and has its tip end 10a cut off by the edge top cutter 6a of the rotating cutter 5 that is rotating.
[0062] [062] On the other hand, the lower electrode tip 10 crosses the respective bundles of bristles 82 of the cover brushes 8, crosses the notch 3b and the communication hole 3a in that order, and is received by the receiver with a lower recess 53 and has its tip end 10a cut by the lower cutting edge 6a of the rotating cutter 5 which is rotating.
[0063] [063] In this case, the compressed air discharged through the discharge nozzle 11a is blown against the cutting edges 6a of the cutting board 6 through the air inlet holes 7b of the cover plate 7 which rotates together with the rotary cutter 5 thereby shaking the parts of the cutting edges 6a and preventing the parts from disturbing the cutting work of the tip ends 10a of the electrode tips 10.
[0064] [064] The parts removed by the lower electrode tip 10 will fly through the open end of the receiver with lower recess 53 and will enter the cover wrap 3, and therefore are prevented from spreading. In the meantime, the parts removed by the upper electrode tip 10 will attempt to fly out through the open end of the receiver with the upper recess 53, but, in fact, they will collide with, and bounce off the cover plate 7, and then they will enter the cover 3 passing through the hollow part 50 and communication hole 3a. In this way, all parts removed by cutting the electrode tips 10 can enter the same cover wrap 3, and are reliably prevented from spreading.
[0065] [065] Additionally, the air inlet holes 7b have an elongated shape, which thus allows the parts removed during the cutting of the electrode tips 10 to be prevented from suddenly passing through the air inlet holes 7b and spread around the tip finisher 1.
[0066] [066] The parts moved into the cover wrap 3 that accumulate in the vicinity of the air suction tool 9 are evacuated from the cover wrap 3 causing the air suction tool 9 to suck air from inside the cover wrap. cover 3. Meanwhile, the parts accumulated in the vicinity of the second air tube 93 inside the cover wrap 3 are forced, by a turbulent air flow (indicated by X1 in figure 4), produced by the compressed air introduced by the second air tube. air 93, floating and traveling in the direction of the air suction tool 9. After that, the parts are evacuated by the air suction tool 9 from the cover wrap 3. In this way, all the parts accumulated inside the air wrap cover 3 are reliably evacuated from cover wrap 3.
[0067] [067] In the embodiment of the present invention described above, the tip finishing element is configured so that the geometric axis of rotation C1 of the rotary cutter 5 extends vertically. However, this is just a non-limiting example. Alternatively, the tip finishing element can also be configured so that the axis of rotation C1 tilts obliquely.
[0068] [068] Furthermore, in the embodiment of the present invention described above, the air inlet holes 7b have a cut shape. However, the air inlet holes 7b can also have a circular shape or a triangular shape, for example.
[0069] [069] Additionally, in the embodiment of the present invention described above, the bristles 82 are made of resin. However, this is just a non-limiting example. Alternatively, the bristles 82 can also be made of a metallic material. Industrial Applicability
