[0023] For the convenience of understanding the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present utility model are given in the drawings. However, the present utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, providing these embodiments is to make the disclosed content of the present utility model more thorough and comprehensive.

[0024] Embodiment 1:

[0025] Please refer to Figures 1-5 , the present utility model provides an auxiliary fixture for machining automobile parts, including a workbench 1 and an electric lifting rod 2. A base 11 is installed on the workbench 1. A long strip-shaped chute 111 is opened on the base 11. The electric lifting rods 2 are symmetrically installed in the chute 111. A fixture for clamping automobile parts is installed at the top of the electric lifting rod 2. The electric lifting rod 2 can adjust its own height, so as to adjust the height of the two fixtures and adapt to fixing special-shaped parts with uneven ends. The bottom of the electric lifting rod 2 is slidably connected to the chute 111. By sliding the electric lifting rod 2 in the chute 111, the distance between the two electric lifting rods 2 can be adjusted to adapt to the installation of parts or special-shaped parts with different lengths and sizes in automobile parts. Multiple strip-shaped grooves are opened on the inner wall of the chute 111. Fixing pins 21 that cooperate with the strip-shaped grooves are symmetrically installed at the bottom of the electric lifting rod 2. The fixing pins 21 are clamped with the strip-shaped grooves, so as to position the electric lifting rod 2 and ensure the stability of the electric lifting rod 2 after adjusting the position and avoid loosening.

[0026] Please refer specifically to Figures 1-3, the fixture includes an L-shaped clamp base 23 which is fixedly installed at the end of the electric lifting rod 2. A clamping block 24 is movably installed on the clamp base 23. A convex block 241 extends on the surface of the clamping block 24 in contact with the clamp base 23. An installation groove 231 is formed in the clamp base 23. The convex block 241 extends into the installation groove 231 and is slidably connected with the installation groove 231. A screw rod 25 is also installed in the installation groove 231. The screw rod 25 passes through the convex block 241 and is rotatably installed in the installation groove 231. The screw rod 25 is threadedly connected with the convex block 241. By rotating the screw rod 25, the convex block 241 and the clamping block 24 are driven to move, so that the clamping block 24 approaches or moves away from the clamp base 23. The structure of the bolt clamps tightly and stably, with a simple and reasonable structure, which is convenient for quickly clamping or releasing the fixation of automotive parts.

[0027] Please refer specifically to Figures 4-5 , a conical surface is provided at the end of the fixing pin 21 close to the strip-shaped groove, and the conical surface fits with the groove in the strip-shaped groove. By inserting the fixing pin 21 into the strip-shaped groove, the electric lifting rod 2 is limited and fixed, ensuring the stability of the fixation of the electric lifting rod 2. A spring 22 is installed between the symmetrically arranged fixing pins 21. Both ends of the spring 22 are fixedly connected with the fixing pins 21. An outward thrust is provided to the fixing pins 21 at both ends through the spring 22, so that the fixing pins 21 are tightly inserted into the strip-shaped groove, ensuring the stability of the fixation of the fixing pins 21.

[0028] Please refer specifically to Figures 4-5 , the fixing pin 21 is also connected with a push block 211. The push block 211 passes through the housing of the electric lifting rod 2 and is movably connected with the electric lifting rod 2. By pushing the push block 211 inward, the fixing pin 21 is driven to move inward, so that the fixing pin 21 is disengaged from the strip-shaped groove, realizing the release of the positioning of the electric lifting rod 2 and facilitating the adjustment of the position of the electric lifting rod 2.

[0029] Please refer specifically to Figure 5 , a limiting groove 112 is further formed along the length direction in the sliding groove 111. A limiting plate 26 is fixed at the bottom end of the electric lifting rod 2. The limiting plate 26 is slidably installed in the limiting groove 112. The electric lifting rod 2 is limited by the limiting plate 26 to prevent the electric lifting rod 2 from falling off the sliding groove 111.

[0030] Please refer specifically to Figures 4-5 , the limiting plate 26 is a square limiting plate 26, and the length of the limiting plate 26 is the same as the width of the limiting groove 112. Through this design, the rotation of the electric lifting rod 2 is restricted, preventing the fixing pin 21 from deviating from the strip-shaped groove due to the rotation of the electric lifting rod 2 and affecting the fixing effect of the electric lifting rod 2.

[0031] Please refer specifically toFigure 1 The base 11 is a circular base 11, and the base 11 is rotatably mounted on the workbench 1 through a rotating shaft. Through this design, the base 11 can rotate around the center. When the clamp clamps and fixes the automobile part, it is convenient to rotate the automobile part for processing, thereby improving the convenience of automobile part processing.

[0032] The working principle of the first embodiment of the utility model is as follows:

[0033] When in use, the push block 211 is pushed inward, and the push block 211 moves to drive the fixing pin 21 to move inward, and at the same time squeezes the spring 22 between the fixing pins 21. The spring 22 is compressed, so that the fixing pin 21 is disengaged from the strip groove, thereby releasing the fixation of the electric lifting rod 2, and adjusting the distance between the two electric lifting rods 2 so that the clamp distance at the end of the electric lifting rod 2 can adapt to the length of the automobile part for clamping. After the position adjustment of the electric lifting rod 2 is completed, the push block 211 is released, and the spring 22 rebounds and resets to push the fixing pin 21 to reset. The fixing pin 21 is inserted into the relative strip groove, which plays a positioning role for the adjusted electric lifting rod 2. The electric lifting rod 2 is extended and retracted to adjust the height of the clamp so that the position of the clamp adapts to the height position of the edge of the automobile part. The edge of the automobile part is placed between the clamp seat 23 and the clamp block 24 of the clamp, and the bolt is turned. The rotation of the bolt drives the protrusion 241 and the clamp block 24 to move. The clamp block 24 moves close to the clamp seat 23 to clamp and fix the automobile part. The operation is simple and fast, and it is suitable for clamping and fixing automobile parts of different sizes, lengths, and special shapes. It has strong adaptability and practicality. After the automobile part is clamped, the base 11 can also be rotated to drive the automobile part to rotate, which is convenient for comprehensive processing operations on the automobile part.

[0034] The above description of the utility model in combination with the accompanying drawings is an exemplary description. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
