The invention relates to a machine tool industry and can be used in the treatment of end surfaces of large diameter in parts with through holes.
The purpose of the invention is to increase the reliability of work and increase the life of the body.
The goal is achieved by the fact that the cutting elements perceive the cutting forces well, and the adjustment elements do not practically undergo cutting forces and, therefore, have little wear.

equal sleeve 3. On the inner side of the casing 1 there are two thrust bearings 4 and 3 rolling, on which the rotating shank 6 is mounted. At the rear end of the casing 1 there is a threaded mounting ring 7 which, in conjunction with the setting screw 8, allows the thrust bearings 4 to be mounted and 5 roll axially without clearance relative to shank 6.
The shank 6 has a larger diameter bit 9 installed over the center, serving as an axial stop for the thrust bearings 4 and 5. The thrust bearing 5, which is closest to the holder, rests with its end on the inner end of the guide sleeve 3.
In the area of the nozzle 9 of increased diameter on the inner side of the casing, the rotation stop 10 is fixed, and there are fastening screws 11 in the corresponding housing openings, the bolt part of which is fixed in the corresponding fastening holes of the rotation stop 10.
In addition, in the rotation limiter 10 there is a precisely positioned hole 12 located co-axially with the hole in the casing 1. A pin enters both holes so that the angular position of the rotation limiter 10 relative to the casing 1 is precisely set. It is important that the angle between the support surfaces 13 and 14 of the rotation limiter 10, which is complete as a circular segment, is exactly 110, which corresponds to the angle of rotation of the shank 6,
To limit the angle of rotation between the shank 6 and the rotation limiter 10 in the shank 6, a ra3 has been selected.
The diagonal groove 15, into which the wedge 16 enters. At the same time, the wedge extends forward in the radial direction of the outer perimeter of the shank 6, so that it, together with the supporting surfaces 13 and 14 of the turn stopper 10, limits the angle of rotation of the shank 6. To facilitate its installation in the groove the bottom surface of the groove has a semicircular shape.
The end of the shank 6 has a slot 17 in the form of a groove in which the fastening tabs 18 are fixed at the rear end of the rod 19 connected to the shank by a plug connection. The hole 20 for mounting the spherical retainer 21 intersects the nest 17 The spherical retainer 21 is enclosed around the outer perimeter by the spring ring 22, which podruzhinivaet and presses the spherical retainer in the area of the socket 17. In the area of the mounting foot 18 of the rod 19, there is a hole 23 in which fixed spherical latch 21.
In this way, a detachable plug connection between the rod 19 and the end of the shank 6 is created. In this case, the rod 19 is fixedly connected to the shank 6, but can be moved in the axial direction. The rod 19 is rotatably mounted in an average longitudinal bore 24 of the guide sleeve, the diameter of the longitudinal bore 24 being larger than the diameter of the adjacent longitudinal bore 25.
At the end of the rod 19, there are two opposing adjustment bolts 26 and 27 with mutual spacing,
The adjusting bolts are fixed in the slots 28 of the cutting elements 29 and 30, which are located opposite each other in the radial groove 31 in the holder 32 and are adjacent to each other on the sides. From the outside, they abut on the respective abutment surfaces 33 and 34 of the holder 32. As a result, the cutting force is transmitted optimally. In this case, the cutting force is sensed by the internal abutment surfaces 33 and 34 of the guide sleeve 3 and through the latter is transmitted to the casing 1 and through the pin in the hole to the stop 10.p turn, and also through the wedge 16 to the shank 6. This allows 994864
There is no need to perceive the stress of the adjusting bolts 26 and 27, which otherwise could easily be subject to wear. Thus, the cutting force is not transmitted to the adjusting bolts 26 and 27, which provide only a radial movement of the cutting elements 29 and 30, i.e. the adjusting bolts 26 and 27 work JO as the pins of the crank in the slots 28 of the cutting elements 29 and 30.
In the event of the rotation of the stem 19, due to the rotation of the shank 6, the adjustment bolts 26 and 27 move along a 15 arc of a circle and fall out of the gable. marked in shaded form to the position shown in solid lines. The cutting elements 29 and 30 are then moved. 20 The wedge 16 is offset with respect to the line passing through the adjusting bolts 26 and 27 by an angle of 35 °. Together with an angle of 110, this provides the desired movement of movement. 25 In some cases of application, it is desirable that the rotation of the shank 6 can be stopped so that the abutment of the wedge 16 into the thrust surfaces 13 and 14 of the turn restrictor 10 does not lead to a return of the shank 6, which primarily occurs at high speeds of rotation. For this purpose, the shank 6 is installed with the possibility of clamping relative to the casing 1. 35 In this case, the clamping is carried out by the fact that in the area of the rotation limiter 10, a conical recess 35 is selected in which the clamping roller 36 enters and tightens in a conical slot. the space of the recess 35 in the direction to the outer perimeter of the shank 6, when the wedge 16 abuts against the supporting surface 14. A similar clamping takes place 5 of the wedge 16 into the opposite supporting surface 13.
Instead of clamping between the shank 6 and the casing 1 in the extreme positions
A corresponding fixation is also provided between the shank 6 and the rotation stop 10, which can be carried out either spring-loaded or magnetically. In the primer making in the zone of the bearing surfaces 13 and 14, when the wedge 16 abuts against them, an appropriate magnetic contact is established between two permanent magnets

polarity, one of which is fixedly connected to the tail 6, and the other is connected to the rotation limiter 10 or the casing 1.
The milling tool allows simple obtaining of the corresponding surfaces 37-40 in the zone of through holes 41 and 42 in the milling mode with forward feed (direction of the arrow I) or in the milling mode with reverse feed (direction of the arrow K, fig. 23).
Milling working body can be performed as follows
The shank 6 is mounted rotatably in the casing 1 on additional ball bearings 43, mainly receiving axial forces. The axial forces of the shank 6 are transmitted to the casing 1 due to the fact that at the same time with the shank 6 there is made an annular flange 44 of increased diameter, to which the ball bearings 43,

The ball bearings 43 are covered at the front and rear by corresponding intermediate discs 45. The rod 19 is connected to the end of the shank 6 by means of a plug connection. At the end of the shank 6 there is a mounting bore 46, which includes the axle pin 47 of the rod 19, the pivot pin 47 in the mounting bore the hole 46 of the shank 6 is carried out by means of a ... (Spherical retainer which is clamped with a clamping screw 48 in the Y-shaped recess of the pin 47 of the rod 19,
The DlTOK 19 is rotatably disposed in the guide sleeve, with the adjusting bolts 26 and 27 of the stem 19 also fitting in. The brake for fixing the case prevents inadvertent movement of the cutting elements from once and forever set position due to the sudden wedge 16 in . the corresponding thrust surfaces of the turn limiter 54, 4Q Brake formed brake braking. 53, which consists of a hollow cylindrical part 57 with a central inner bore 58, while the brake shell 53 has an annular
the grooves of the cutting elements 29 and 30,
The end of the holder 32 is formed by a 45-F-Flange 59 of reduced diameter, with which it rests on the respective ball bearing 49 and is positioned thereonably rotatable. On the inner surface of the braking pin with the possibility of a connector the closing pin 48,
The axial clearance of the ball bearings 49 is controlled by means of a closing disk 50 adjacent from the butt side to the inner surface of the threaded mounting ring 51, which can rotate relative to the casing 1, the Tarelchat spring 52 adjusts the axial clearance of the ball bearing 49 and the brace 53 located above it,
Thereby, the brake bracket 53 is rotatably located relative to the casing 1 on an axially adjustable ball bearing 49,
The rotation stop 54 serves to ensure that, when the rotation direction of the shank 6 is changed relative to the housing J, there is no accidental movement of the incisors from the set position due to the wedge 16 being too firmly fixed to the corresponding support surfaces of the rotation stop 34.
The shank 6 is connected to the wedge 16, which projects radially above the outer surface of the shank 6, and with the corresponding stop surfaces of the segment-shaped turn restrictor 54, which, in turn, is fitted with a tight fitting bolt 55 to the casing 1.
A second wedge 56 can be installed. However, only either the wedge 16 or the wedge 56 is permanently applied. When there is a wedge 16 in this state, the cutting elements 29 and 30 are in the holder 32 in the shifted position, whereas when using the wedge 56 elements 29 and 30 are in the position removed from the holder 32.
The brake for fixing the cover prevents inadvertent movement of the cutting elements from once and forever to the set position due to the sudden stop of the wedge of 16 c. corresponding stop surfaces of the turn limiter 54, the brake is formed by a brake skid 53, which consists of a hollow cylindrical part 57 with a central inner bore 58, while the brake shell 53 has an annular
a smaller diameter recess 59, with which it rests on the corresponding ball bearing 49 and is rotatably disposed thereon. Holes 60 are made on the inner surface of the caliper 53, which are tangential with respect to the circumference of the inner hole 58 and partially cross this hole. In each hole
60 a brake ball 61 is placed with the possibility of moving in the axial direction. The ends of the hole 60 are formed by spring-loaded pins 62, which are located in
a hole in one straight hole 63 in the bracket 53. Springs .64 are located in the holes 63 and act on the spring-loaded pins 62 so that they can enter into the opening 60 of the CO side of its end face.
The corresponding ball 61 in one or in another extreme position comes into contact with the end of the corresponding spring-loaded pin 62.
The holes 63 are closed with threaded plugs.
There is a brake plate 65, which is connected to the brake caliper 53 with two screws 66. The brake plate 65 is also located tangentially with respect to the inner perimeter of the inner bore 58 and runs parallel to the longitudinal axis of the corresponding bore 63.
When the casing 1, which passes in the inner hole 58, rotates, the corresponding brake ball 61 moves in the hole 60 or moves to one of the extreme positions along arrow L or to another extreme position along arrow M. In the braking position, the upper brake ball 61 moves along Arrow L tog-30 gummy pin 73, which passes through the distance, when the casing rotates along arrow H relative to the brake caliper, and vice versa, the brake ball 61 moves in arrow M, when casing 1 rotates along arrow O with respect to 35 brake caliper 53.
When the brake ball 61 passes from moving along arrow M to moving along arrow L, it in brake position 40 falls under brake 40 plate 65 and presses casing 1, which is located in inner hole 58, because the tangential hole 60 partially intersects inner hole 58. Therefore, the brake - the ball 61 forms a friction link with the brake plate 65 from above and a friction link with the casing 1 at the bottom. When the ball moves in
bolt version 70.
The sleeve 72 is connected to the thread with a finger, which is correspondingly connected to the part 7A of the machine body.
The spring-loaded bolt 70 is fixed in the sleeve 75, which is firmly connected to the bracket 67 by the threaded rod 76.
To facilitate fixation of the bolt 70 in the sleeve 75, the latter has a bevel 77 in the outer circumference of the corresponding bore.
 The sleeve 75 can be fixed to the machine body part 74, while the machine can be mounted on the bracket 67.
The device is mounted on a clamping cone 69. Bolt 70 first
the reverse direction occurs short-Q is not fixed in sleeve 75 on
Slowing down the casing rotation 1.
The brake thus contributes to the fact that, with each change in the direction of rotation of the shank 6 relative to the casing 1, the corresponding brake ball 61 passes under the brake plate 65 in order to fall into another extreme position. Due to
This shank 6 is experiencing a short-term effect of a braking force and immediately continues to turn in another direction.
The purpose of this braking force is to ensure that during the rotation of the rod 19, the cutting tools 29 and 30 do not spring, i.e. only one or another extreme position is continuously assigned to each element 29 and 30, avoiding unacceptable intermediate positions.
When the brake caliper 53 is stationary with the machine, it is connected to the bracket 67. It is possible, with axial fastening and fastening of the machine cone 68, to bring the device with its tailing 6 and the clamping cone 69 located on it to a certain position of rotation relative to the machine cone 68 machine.
This is done by means of a spring-loaded bolt 70, which is held by the force of the spring 71 in the sleeve 72 so that it can move in the axial direction, and the bolt 70 prevents the bolt 70 from falling out.
The sleeve 72 is connected to the thread with a finger, which is correspondingly connected to the part 7A of the machine body.
The spring-loaded bolt 70 is fixed in the sleeve 75, which is firmly connected to the bracket 67 by the threaded rod 76.
To facilitate fixation of the bolt 70 in the sleeve 75, the latter has a bevel 77 in the outer circumference of the corresponding bore.
 The sleeve 75 can be fixed to the machine body part 74, while the machine can be mounted on the bracket 67.
The device is mounted on a clamping cone 69. Bolt 70 first
bracket 67.
When the machine is started up, the device rotates idle for a certain angular rotation until the bolt 70 is in the position determined with respect to the sleeve and is locked in this position.
Thus, the brake bracket 53 is firmly connected to the part
 the machine body, whereas only VOSTOVIK 6 is rotated in one direction or another to ensure the input or output of the cutting elements, and otherwise the whole casing 1 j completes circular motions with cutting elements in the shifted or ejected position.
As another example, a machining process is introduced, in which 10 the guide sleeve 3 passes through the through hole of the workpiece with cutting elements 29 and 30 in the shifted position, and enlarges a larger diameter in the workpiece to the through hole. By appropriate rotation of the shank 6, the incisors are extended, and the entire casing 1 of the milling device is rotated so that the recess in the workpiece is milled when the device moves along arrow P.
