[0002] Auto parts are the various units that make up the whole of a car and a product that serves the car. All parts, assemblies, components and assemblies suitable for use in a car are collectively referred to as auto parts. When processing auto parts, positioning fixtures should be used in advance to clamp the parts to facilitate processing by the staff.

[0003] The patent with the patent authorization announcement number CN218137450U discloses a positioning fixture for automobile parts processing, including: a bottom plate, a motor is embedded on the right side of the top of the bottom plate, the output shaft of the motor is fixedly connected to a driving gear, and the left side of the top of the bottom plate is rotatably connected to a driven gear 1, and the driven gear 1 is meshed with the driving gear. Although the above patent can fix automobile parts before processing to avoid the position of automobile parts from being offset, there are still some shortcomings in actual use. For example, when fixing automobile parts, the automobile parts are fixed by two clamping plates, and the two clamping plates can only contact two edges of the automobile parts, and the fixing effect is not good. When fixing automobile parts with uneven edges such as gears, it is easy to damage the surface of the automobile parts, so it is only suitable for fixing automobile parts with relatively flat edges, resulting in low applicability of the positioning fixture.

[0004] Therefore, there is a particular need for a positioning fixture for processing automotive parts with high applicability to solve the problems existing in the prior art. Utility Model Content

DETAILED DESCRIPTION

[0021] Embodiment: A positioning fixture for processing automobile parts, see Figure 1-Figure 4As shown, it includes a mounting plate 1, a connecting block 7, a supporting ring 9, a clamping block 901, a screw rod 11, handmade plasticine 10, a knob 12 and a placement block 13. At least three circular mounting holes are provided on the left side of the mounting plate 1. The right side of the mounting plate 1 is connected to the connecting block 7 by welding. The connecting block 7 is slidably and rotatably connected to the supporting ring 9. Two clamping blocks 901 are connected to the supporting ring 9 by welding. The connecting block 7 is provided with a clamping groove 8 and a limiting slide groove 801 distributed up and down, and the clamping groove 8 is communicated with the limiting slide groove 801. The clamping block 901 is clamped with the clamping groove 8, so that the support ring 9 is fixed on the connecting block 7. A plurality of screw rods 11 distributed circumferentially are threadedly connected to the support ring 9. The ends of the plurality of screw rods 11 close to each other are connected to the handmade plasticine 10. The ends of the plurality of screw rods 11 away from each other are connected to the knob 12 for assisting rotation by welding. The right side of the connecting block 7 is connected to the placement block 13 by welding. The handmade plasticine 10 moves inward by rotating the screw rod 11.

[0022] See also Figure 1-Figure 3 As shown, it also includes a motor 14, a turntable 15, a slide column 18 and a clamping block 19. The motor 14 is connected to the center position of the connecting block 7 by bolts. The turntable 15 is rotatably connected to the placement block 13. The output shaft of the motor 14 is fixedly connected to the turntable 15. The turntable 15 is provided with a plurality of arc-shaped slide grooves 16 evenly spaced. The placement block 13 is provided with a straight slide groove 17 evenly spaced. The straight slide groove 17 is slidably connected with a slide column 18, and the slide column 18 is slidably connected to the arc-shaped slide groove 16. The right end of the slide column 18 is connected to the clamping block 19, which is made of silicone. The turntable 15 is rotated by the operation of the motor 14, so that the arc-shaped slide groove 16 pushes the slide column 18, and the slide column 18 moves inward along the straight slide groove 17.

[0023] See also Figure 1 and Figure 2 As shown, it also includes a hollow bracket 2, a slide rod 3, a threaded rod 5, a support plate 6 and a guide rod 4. The lower part of the mounting plate 1 is connected to the front and rear distributed hollow brackets 2 by welding. The slide rod 3 is slidably connected inside the hollow bracket 2. The right side of the slide rod 3 on the front side is threadedly connected to the threaded rod 5. The upper end of the threaded rod 5 is connected to a hexagonal rotating block by welding, and is rotatably connected to a support plate 6 made of plastic material. The support plate 6 is an arc-shaped plate for supporting rod-shaped automotive parts. The rear side of the support plate 6 is connected to the guide rod 4 by welding. The guide rod 4 is slidably connected to the slide rod 3 on the rear side. The support plate 6 moves upward by rotating the threaded rod 5.

[0024] First, the staff uses tools to install the mounting plate 1 on the wall, and then turns on the motor 14. The output shaft of the motor 14 drives the turntable 15 to rotate, so that the arc-shaped slide groove 16 pushes the slide column 18, and then the slide column 18 moves inward along the straight slide groove 17. When the slide column 18 moves inward to the limit, the motor 14 is turned off, and then the automobile parts are placed on the placement block 13, and multiple clamping blocks 19 are placed in the round holes of the automobile parts to prevent the clamping blocks 19 from interfering with the placement of the automobile parts. Then, the knob 12 is pinched by hand to rotate the screw rod 11 in turn, so that the handmade plasticine 10 moves inward to clamp the automobile parts. When clamping, the handmade plasticine 10 is deformed and fits tightly to the surface of the automobile parts, so as to facilitate the firm clamping of automobile parts with uneven edges and improve the applicability of the positioning fixture. When it is necessary to clamp the rod-shaped automobile parts, the staff turns on the motor 14 again, controls the output shaft of the motor 14 to reverse and drives the turntable 15 to reverse, so that the arc-shaped slide groove 16 pulls the slide column 18, and then the slide column 18 moves along the straight slide groove 17. When the straight slide groove 17 moves outward and the slide column 18 moves outward to a suitable position, the automobile parts are placed on the placement block 13, and then the output shaft of the motor 14 is controlled to rotate, so that the slide column 18 drives the clamping block 19 to move inward to clamp the automobile parts, thereby facilitating the clamping of the rod-shaped automobile parts and further improving the applicability of the positioning fixture. After clamping, the motor 14 is turned off, and the slide rod 3 is pushed to the left to align the support plate 6 with the right end of the rod-shaped automobile parts, and the threaded rod 5 is rotated to make the support plate 6 move upward to support the rod-shaped automobile parts, thereby improving the stability of the rod-shaped automobile parts and facilitating processing by the staff. Then the staff rotates the support ring 9 to a suitable angle to disengage the clamping block 901 from the clamping groove 8 and align it with the limiting slide groove 801, and then push the support ring 9 to the left to make the clamping block 901 slide into the limiting slide groove 801, and then adjust the position of the support ring 9 to make the handmade plasticine 10 flush with the placement block 13 to prevent the handmade plasticine 10 from interfering with the processing of the rod-shaped automobile parts.
