    MULTI POINT FIXABLE LOCATOR FOR USE IN A CAR ASSEMBLY LINE
    The present invention relates to a jig position fixture of the vehicle frame to move each assembly process in the state of hanging the body of the car body on the jig of the moving rail spaced a certain distance from the ground during the assembly process for producing a car. More specifically, it relates to a jig position fixture of the vehicle frame that improves the problem that the precision is poor in fine positioning due to the structural problems of the stopper and rocker arm when fixing the position of the conventional jig to any position of the rail.
    In general, the body of a vehicle made by pressing various kinds of panels in the assembly line of an automobile through welding work is connected by a jig 1 connected to a jig housing main body 7 coupled to a conveyor rail connecting each assembly line. The height distance of the body body 100 is adjusted to maintain a constant distance from the ground is suspended on one end of the jig (1). In addition, the main body 100 of the vehicle suspended by maintaining a certain distance from the ground moves along the conveyor rail at a constant speed to automatically pass between each work line. At this time, the assembly of the vehicle is made by each worker to assemble the parts of the main body 100 of the moving car body.
    According to FIG. 2, which shows a schematic structure of the main body 7 of the jig housing, the jig housing main body 1 has a lower end of two brackets 11 extending downward from the conveyor rail. It is configured to be connected to the upper surface of the. In addition, the jig housing main body 1 has a structure that is coupled to the moving rail (3) is movable in parallel along the inner surface of the moving rail (3) by a roller 15 configured inside the main body (1) of the housing. .
    The distance between the jig 1 can be narrowed or widened so that the distance of the jig 1 connected to the main body 1 of the housing can be matched with the body body 100. The jig 1 can be fixed at an arbitrary position. A plurality of stoppers 13 protruding from the lower surface of the moving rail 3 were continuously installed so as to be possible. One end of the actuating lever 9 formed on the outside of the housing main body 7 is connected to one end of the rocker arm 12 which is connected to the inside of the housing and is integral with the position fixing unit 11.
    The jig position fixture of the existing vehicle frame configured as described above is pushed down the actuating lever (9) by the rocker arm 12 and the rocker arm (12) configured inside the jig housing main body (7) integrally formed with the actuating lever (9) Position fixing device 11 configured at one end of the pivot) pivots at an angle downward with respect to the hinge composed of one end of the operating lever (9) and the housing body (7). Thus, the position fixture 11 is separated from the groove formed between the stopper 13 and the stopper 13 and the main body 7 of the jig housing is the surface of the moving rail 3 by the roller 13 and the moving rail 3. It was possible to move along.
    Meanwhile, as the jig housing main body 7 moves, the jig 1 connected to the main body 7 of the housing moves in the axial direction of the moving rail 3 and adjusts a distance of a desired size to move the body 100 of the vehicle body 100. Could be monthly
    However, the position fixing means 11 is fixed between the stopper 13 when fixing the jig housing main body 7 by the stopper 13 which is continuously spaced a predetermined distance from the lower surface of the moving rail 3. Due to the size of the position fixture 11 coupled between the interior of the formed grooves it is impossible to move the amount less than the length of the position fixture 11 when fixing the position fixture 11 was unable to precise movement. Therefore, the accuracy at the time of fixing the vehicle body to the jig 1 could not be guaranteed.
    In addition, when the position holder 11 is inserted between the stoppers 13, the vertical surface of the position holder 11 and the vertical wall surface of the stopper 13 are not vertically coupled, and the operating lever 9 and the housing body 7 The flow was generated due to the play caused by the pivoting and insertion with respect to the coupling hole 13 of). And inconvenience caused by having to install the stopper 13 continuously on the lower surface of the moving rail (3).

    In order to achieve the above object, the present invention is a jig formed in a form that can be largely worn over the body of the vehicle, jig housing main body 50 is connected to the jig, a rotary gear configured in the main body 50 of the jig housing (27), the fixed bar 29 for connecting the fixed gear 25, the operating lever 23 for forming the operating force, the operating arm 35 for transmitting the operating force, and the fixed bar 29 to the original position It consists of the spring 31 which recovers, and the rack 21 formed in the surface of the moving rail 55. As shown in FIG.
    Looking at the specific embodiment of the present invention with reference to the accompanying drawings, as shown in Figures 3 and 4, the interior of the main body 50 of the jig housing coupled to the moving rail 55 having a cross-section of the "I" shape A fixed gear 25 is formed around a gear shaft vertically penetrating a portion of the wall surface of the housing, and has the same pitch circle as the pitch circle of the fixed gear 25 and the teeth having the same size as the teeth of the fixed gear 25. The rotating gear 27 which has is provided in parallel with the gear shaft of the fixed gear 25.
    In addition, a straight rack 21 is formed to coincide with two points of the teeth positioned at the top of the fixed gear 25 and the rotary gear 27, and the opposite surface of the rack 21 is the upper plate of the moving rail 55. Is coupled to the lower surface of the. Then, the gear shaft of the fixed gear 25 and the gear shaft of the rotary gear 27 are protruded, and the fixed bar 29 having a coupling hole is formed in the same distance as the distance between the centers of the protruding gear shafts so as to be formed with the respective gear shafts. At this time, the gear shaft of the fixed gear 25 is coupled to the connection hole 42 provided in the housing body 50 through the fixed bar 29.
    The fixing bar 29 extends in parallel with the rack 21 about the fixing gear 25. An extended side of the fixing bar 29 has a predetermined length to the left and right with respect to the center line of the fixing bar 29 and constitutes a bisected cutout, and a perturbing pin 53 is disposed parallel to the gear axis in the center of the cutout. Is formed. On the other hand, the operation arm 35 having a clamping portion cut up and down in the distal end so that the perturbing pin 53 horizontally fitted to one end of the fixing bar 29 is extended at a predetermined length horizontally. It extends with a certain angle downward. In addition, a connection shaft 41 having a circular cross section is connected to the lower end of the operation arm 35. In addition, the connecting shaft 41 is coupled to the lower end of the operating lever 23 through the coupling hole 39 provided in the main body 50 of the housing.
    The actuating lever 23 formed outside the main body 50 of the jig housing has the same angle as the main body 50 of the actuating lever 23 in the upper direction and is equal to the height of the upper surface of the jig housing main body 50. Is extended. And one side of the upper portion of the main body 50 of the operating lever 23 is coupled to one end of the round bar provided with a circular handle perpendicular to the upper surface of the housing main body 50.
    Meanwhile, a spring 31 is coupled to a lower portion of the tip of the operation arm 35 embedded in the main body 50 of the jig housing, and a spring support end perpendicular to the wall surface of the inner surface of the housing so as to be in contact with the lower surface of the spring 31. 33) is formed to protrude.
    Looking at the embodiment of the present invention configured as described above with reference to the accompanying drawings, the fixed gear 25 and the inside of the housing main body 50 of the jig as shown the operation principle of the jig position fixture of the vehicle frame of FIG. The rotary gears 27 are engaged with each other and the respective gear shafts are fixed with the fixing bar 29.
    When the operating force is transmitted from the outside of the jig housing main body 50 through the operation lever 23 to the operation arm 35 connected to the perturbing pin 53 configured at one side of the fixed bar 29, the operation lever 23 Pivots downward and the connecting shaft 41 coupled to the lower portion of the operating lever 23 rotates. Therefore, the operating arm 35 connected with the connecting shaft 41 pivots downwardly at a predetermined angle with respect to the connecting shaft 41 and compresses the spring 31. At the same time, the clamping part cut up and down of the operation part 35 transmits the operation force in the downward direction to the perturbing pin 53 provided at the center of the tip of the fixing bar 29, and the operating force is transmitted to the rotary gear 27. Is transmitted to the gear shaft. At this time, the fixed gear 25 coupled to the jig housing main body 50 of the gear is maintained in a fixed state.
    Therefore, the rotational force transmitted through the fixed bar 29 rotates the rotary gear 27 and the teeth formed on the outer circumferential surface of the rotary gear 27 are bitten by the teeth of the fixed gear 25 and the outer circumferential surface of the fixed gear 25. Will rotate along. At this time, the teeth of the rack 21 coupled with the teeth of the top of the rotary gear 27 is spaced apart and only the teeth of the fixed gear 25 is in contact with the teeth of the rack 21.
    Due to the above action, the rack 21 of the movable rail 55 and the teeth of the rotary gear 27 are spaced apart so that the main body 50 of the jig housing, which has been fixed, moves when an operator force or other external force is applied. It moves along the rail 55. In addition, when the actuation force applied to the actuation lever 23 is released, the actuation arm 35 is returned to its original state by the repulsive force of the spring 31 compressed under the distal end of the actuation arm 35 and is fixed to the fixed bar 29. By pulling up the provided perturbing pin 53, the teeth of the outer circumferential surface of the rotary gear 27 connected to the fixed bar 29 rotate about the axis of the fixed gear 25 and are located on the upper side of the movable rail 55. It coincides with the teeth of the rack 21. Therefore, the main body 50 of the jig housing is maintained in a fixed state due to the engagement of the teeth formed on the top of the fixed gear 25 and the rotary gear 27.
    According to the present invention configured as described above in the jig position fixture of the vehicle frame, when the body body of the vehicle is spaced apart from the ground by a certain height and mounted on the jig due to the size of the stopper and the size of the stopper installed in the jig. The amount of movement smaller than the size of the positional fixture can solve the difficulty of adjusting, thereby enabling the movement of more precise and fine jig. Therefore, various types of vehicles can be fixed to the jig, and since the stopper is not installed on the moving rail, the main body of the jig housing can be fixed anywhere on the moving rail, thereby eliminating the restriction of the moving section and fixing the housing body. When this is done, no play occurs in the housing body, preventing flow and resulting in a secure fixation of the jig.
