Description

Technical Field

[0001] This utility model relates to the field of transmission technology, and in particular to a welding fixture structure for a reverse gear shift fork shaft assembly. Background Technology

[0002] An automotive transmission is a gear transmission device that can fix or change the transmission ratio between the output shaft and the input shaft in different gears. Reversing is a common operation for automobiles, and the automotive transmission shift mechanism includes a reverse gear mechanism. By changing the gear transmission relationship of the automotive transmission through the reverse gear mechanism, reversing is achieved. The reverse gear mechanism mainly includes a reverse gear shift fork shaft, a reverse gear shift fork, and a locking mechanism. The components of the reverse gear mechanism are machined separately and then assembled by welding.

[0003] The existing welding fixture structure still has the following problems:

[0004] 1. Some welding fixtures have a single fixed structure for the reverse gear shift fork shaft assembly and lack a flexible adjustment mechanism, resulting in low applicability and versatility. They are difficult to adapt to the size, shape and welding requirements of different specifications of components and cannot meet the diverse production needs.

[0005] 2. Although some welding fixtures have height adjustment functions, most of them are manually adjustable. Manual height adjustment indirectly reduces the user's work efficiency, resulting in low efficiency and difficulty in accurate positioning.

[0006] A search revealed Chinese Patent Publication No. CN220636820U, which discloses a welding fixture structure for a reverse gear shift fork shaft assembly. The structure includes a welding fixture body, a working area in the middle of the top of the welding fixture body, a rotating shaft on one side of the top of the welding fixture body, a dust cover on the top of the rotating shaft, and a handle on one side of the top of the dust cover. This invention adjusts the height of the welding fixture structure body by cooperating with the main body, working area, rotating shaft, dust cover, handle, slot, and magnet to meet the height requirements of different users. The adjustment seat, screw, base, adjustment ring, and anti-slip particles improve the dustproof performance of the welding fixture structure, preventing dust or stubborn dirt from adhering to the working area during long-term use and affecting user operation. However, this device still has limitations: the welding fixture structure has a single fixed position on the reverse gear shift fork shaft assembly and lacks a flexible adjustment mechanism, resulting in low applicability and versatility. It is difficult to adapt to the size, shape, and welding requirements of different components, failing to meet diverse production needs. Furthermore, although the welding fixture structure has a height adjustment function, it is manually adjustable, which indirectly reduces user efficiency, leading to inefficient height adjustment and difficulty in precise positioning.

[0017] The above-mentioned solution has the following beneficial effects:

[0018] 1.

[0029] Reference Figure 1-4 This utility model discloses a welding fixture structure for a reverse gear shift fork shaft assembly, comprising a worktable 1. A servo motor 8 is fixedly mounted on the upper left side of the worktable 1, and a mounting block 11 is fixedly mounted on the upper right side of the worktable 1. The output end of the servo motor 8 is connected to a lead screw 9 via a coupling. The end of the lead screw 9 away from the servo motor 8 is rotatably mounted within the mounting block 11. A positioning block 10 is fitted onto the lead screw 9 and slidably mounted on the upper end of the worktable 1. Two slide rails 7 are fixedly mounted on both sides of the upper end of the worktable 1, located between the servo motor 8, the lead screw 9, and the mounting block 11. Several positioning blocks 12 are slidably mounted on each of the two slide rails 7. When in use, according to the shape and size of the reverse gear shift fork shaft assembly, servo motor 8 is started to drive the lead screw 9 connected to the output end of servo motor 8 via a coupling to rotate. At the same time, positioning block 10 is adjusted to a position that adapts to the shape of the reverse gear shift fork shaft assembly. Then, positioning block 12 is slidably adjusted on slide rail 7 to adapt to the size of the reverse gear shift fork shaft assembly. By setting servo motor 8, lead screw 9, positioning block 10, slide rail 7 and positioning block 12, the size, shape and welding requirements of different specifications of components can be adapted during use, which can meet diverse production needs, thereby improving the applicability and versatility of the welding fixture structure for the reverse gear shift fork shaft assembly.

[0030] A mounting base 1 5 is fixedly installed at the bottom of the workbench 1. A mounting base 2 6 is slidably installed on the mounting base 1 5. A servo motor 2 15 is fixedly installed inside the mounting base 2 6. The output end of the servo motor 2 15 is connected to a lead screw 2 13 via a coupling. Two limit posts 14 are fixedly installed inside the mounting base 2 6, located on both sides of the servo motor 2 15. The mounting base 1 5 is fitted onto the lead screw 2 13 and slidably installed on the limit posts 14. In use, the servo motor 2 15 is started to drive the lead screw 2 13, which is connected to the output end of the servo motor 2 15 via a coupling, to rotate. At the same time, the mounting base 1 5, which is fitted onto the lead screw 2 13 and slidably installed on the limit posts 14, is driven to rise, thereby driving the height adjustment of the welding fixture structure body. By setting up the servo motor 2 15, limit posts 14, lead screw 2 13, mounting base 1 5, and mounting base 2 6, the height adjustment of the welding fixture structure body is automatically adjusted, improving work efficiency and the efficiency of the height adjustment method, and enabling precise positioning.

[0031] Fixed blocks 3 are fixedly installed at the four corners of the workbench 1. Rotating shafts 4 are rotatably installed between two fixed blocks 3. Dustproof boxes 2 are fixedly installed on the rotating shafts 4. An arc-shaped groove 16 is opened at the bottom of one end of each dustproof box 2, which is adapted to the rotating shaft 4. An installation groove 17 is opened at the front end of each dustproof box 2, and a sealing strip 18 is set in the installation groove 17. The rotating shaft 4 is installed in the fixed block 3 by rotation, providing a flexible support base for the dustproof box 2 to rotate, so that the dustproof box 2 can be opened and closed easily. When two dustproof boxes 2 are locked together, the sealing strips 18 on the edges fill the gaps to form a relatively closed space, effectively preventing dust, oil and other impurities from entering the working area. At the same time, the dustproof box 2 avoids the problem of dirt adhesion affecting operation due to long-term exposure of the working area. It not only improves the dustproof performance of the welding fixture structure, reduces the frequency and cost of equipment maintenance, but also ensures the cleanliness of the working area, indirectly improving the stability of welding operation and product quality, and enhancing the practicality and applicability of the fixture structure.

[0032] Working principle: When a reverse gear shift fork shaft assembly welding fixture structure is put into use, the servo motor 15 is started to drive the lead screw 13 to rotate, which in turn drives the mounting seat 5, which is fitted on the lead screw 13 and slidably mounted on the limit post 14, to rise, thereby driving the welding fixture structure body to adjust its height. Then, according to the shape and size of the reverse gear shift fork shaft assembly, the servo motor 8 is started to drive the lead screw 9 to rotate, which in turn adjusts the positioning block 10, which is fitted on the lead screw 9, to a position that adapts to the shape of the reverse gear shift fork shaft assembly. Then, the positioning block 12 is slidably adjusted on the slide rail 7 to adapt to the size of the reverse gear shift fork shaft assembly.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
