[0002] The slide rail is an important mechanical component of the seat. Common slide rails are mainly installed under the seat and are used to adjust the front, back, left, and right positions of the seat. The mechanism generally consists of an upper rail, a lower rail, a locking mechanism (manual), an adjustment mechanism (electric), ball rollers, and a ball roller cage.

[0003] During the processing of slide rails, it is usually necessary to weld parts inside the slide rails. When welding slide rails in the existing technology, the positioning pins are usually passed through the positioning holes on the slide rails, and then the parts are placed in a specific position for welding. However, since the position of the positioning pins on the existing welding equipment is fixed, and the distance between the two positioning holes on the slide rails is uncertain, the existing welding equipment can only weld a single type of slide rail. Although some existing welding equipment can also adjust the position of the positioning pins, since the existing adjustment methods are mostly manual adjustments, there may be errors in the distance the positioning pins on both sides move during adjustment, making it impossible for the two positioning pins to align with the positioning holes, requiring multiple debugging, which greatly reduces the welding efficiency of the slide rails. Therefore, it is necessary to design multi-type slide rail automatic change welding tooling to solve the above problems. Utility Model Content

[0023] Among them, a pressure cover assembly is provided on the workbench 1, and the pressure cover assembly includes a clamping cylinder 3 arranged on the workbench 1, a rotating shaft 4 is passed through the clamping cylinder 3, and a handle 5 is fixedly connected to the left and right sides of the rotating shaft 4. A connecting block 6 is fixedly connected to the rotating shaft 4, and the lower end of the connecting block 6 is fixedly connected to the crossbeam 7. Multiple crossbeams 7 are provided with circular openings, and a T-shaped cylinder is passed through each circular opening. Each T-shaped cylinder is elastically connected to the lower end of the crossbeam 7 by a spring 8. A rectangular plate is fixedly connected to the left side of the crossbeam 7, and a cover plate 9 is fixedly connected to the lower end of the rectangular plate. The two T-shaped cylinders on the left side pass through the cover plate 9.

[0024] Among them, the upper end of the workbench 1 is fixedly connected to two third mounting seats 22, the upper ends of the two third mounting seats 22 are fixedly connected to support blocks 27, the upper ends of the two support blocks 27 are fixedly connected to two rectangular blocks 28, and the two rectangular blocks 28 are each provided with a through opening 26. The two positioning pins 11 on the left side pass through the corresponding through openings 26. The two through openings 26 are both elliptical, so that the two positioning pins 11 on the left side can only move within a small range within the through openings 26.

[0025] Among them, two clamping assemblies are provided on the workbench 1, and the clamping assembly includes a second mounting seat 19 arranged at the upper end of the workbench 1, and a plurality of telescopic rods are fixedly connected to the second mounting seat 19, and the telescopic ends of the plurality of telescopic rods are commonly fixedly connected to a push plate 23, and a top block 24 is fixedly connected to the left side of the push plate 23. A second cylinder 20 is installed on the second mounting seat 19, and the telescopic end of the second cylinder 20 is fixedly connected to the push plate 23. A placement block 25 is fixedly connected to the right side of the fixed plate 12 located on the left side, and a circular opening is provided on the placement block 25, and the top block 24 passes through the circular opening.

Two scales 2 are fixedly connected to the upper end of the workbench 1. The two scales 2 are set so that in the initial state, the initial positions of the two sliding cylinders 10 need to be adjusted to zero. However, it can be judged whether the stretching lengths of the two sliding cylinders 10 are consistent based on the subsequent operation of the sliding cylinder 10.

[0027] The functional principle of the present invention can be explained through the following operation mode: when welding the slide rail, first, the distance between the two corresponding positioning pins 11 is adjusted according to the distance between the two positioning holes on the slide rail. When adjusting the distance between the positioning pins 11, the two servo motors 21 are first controlled to operate, so that the two slide cylinders 10 are stretched, so that the multiple positioning pins 11 are moved, and the positions of the positioning pins 11 are adjusted;

[0028] Then, the two parts are placed between the placement block 25 and the rectangular block 28. The second cylinder 20 is then controlled to operate, so that the two push plates 23 drive the top block 24 to move leftward to limit the position of the parts. Since the distance between the welding position of the parts and the positioning holes is always kept constant, when the slide rail is placed on the two positioning pins 11, the parts can be quickly positioned at the welding position.

[0029] When the slide rails are placed, the clamping cylinder 3 automatically rotates the handle 5 downward, so that the handle 5 drives the cover plate 9 to rotate downward, thereby providing protection to prevent welding slag from splashing to the outside during subsequent welding, and at the same time, the two slide rails can be pressed tightly against the device.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
