The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a welding fixture for processing automotive tie rods to prevent deviation, comprising a support block 1, a shifting mechanism 5, and a locking mechanism 6. Two sets of clamping plates 4 are arranged above the support block 1; the shifting mechanism 5 is located above the support block 1 and includes a C-shaped plate 501. Multiple sets of symmetrically arranged C-shaped plates 501 are fixedly installed on adjacent sides of the clamping plates 4; the locking mechanism 6 is located above the support block 1 and includes a circular block 601, limiting holes 602, a connecting rod 603, and a pull ring 606. Multiple sets of annularly distributed limiting holes 602 are provided on the outer wall of the circular block 601. The interior of the clamping plate 4 is slidably connected to the outer wall of the plug-in rod 603. One end of the plug-in rod 603 extends into the interior of a set of limiting holes 602, and the other end of the plug-in rod 603 is provided with a pull ring 606. The interior of the support block 1 is provided with a sliding cavity 2. Two sets of symmetrical internal threaded blocks 3 are slidably installed on the inner wall of the sliding cavity 2. The top of the internal threaded blocks 3 is fixedly connected to the bottom of the clamping plate 4. The front and rear inner walls of the sliding cavity 2 are rotatably installed with bidirectional threaded rods 7. The front side of the support block 1 is fixedly installed with a reduction motor 8. The output shaft of the reduction motor 8 is fixedly connected to one end of the bidirectional threaded rod 7. The two sides of the support block 1 are fixedly installed with connecting plates 9.

[0023] Secondly, the shifting mechanism 5 also includes a rotating rod 502 and a concave roller 503. A set of rotating rods 502 are rotatably installed on the inner top of the C-shaped plate 501. The outer wall of the rotating rod 502 is fixedly connected to the inside of the concave roller 503. The inner wall of the concave roller 503 is provided with a protective rubber pad. The position of the horizontal tie rod can be moved without removing it, reducing the time consumption of the picking and placing process, improving the welding efficiency of the horizontal tie rod, and making the operation simple and easy to use.

[0024] Furthermore, the locking mechanism 6 also includes a spring 605 and a partition plate 604. A set of rotating rods 502 passes through the C-shaped plate 501 and is fixedly connected to the top of the circular block 601. The outer wall of the plug rod 603 is fixedly connected to the inside of the partition plate 604. The front side of the partition plate 604 is fixedly connected to one end of the spring 605.

[0025] Working principle: In use, the device is fixed to the welding equipment via the connecting plate 9. The car tie rod is placed between the concave rollers 503. The geared motor 8 is turned on to drive the bidirectional threaded rod 7 to rotate. Under the limit of the sliding cavity 2, the two sets of internal threaded blocks 3 slide, causing the two sets of clamping plates 4 to move towards each other, so that the tie rod is clamped between the concave rollers 503 for welding. When it is necessary to move the position of the tie rod, the plug rod 603 is pulled outward by the pull ring 606, which drives the partition plate 6 04. Move and compress the spring 605, so that one end of the plug rod 603 moves out of the limiting hole 602, and the limiting of the circular block 601 is removed. Then the horizontal tie rod can move between the concave rollers 503. After adjusting the position, release the pull ring 606. Under the elastic action of the spring 605, push the partition plate 604 to move, so that the plug rod 603 is inserted into the limiting hole 602 to limit the circular block 601, and the rotating rod 502 is locked to prevent the concave rollers 503 from continuing to rotate.
