[0003] For example, CN 219465222 U discloses a fixture for welding shift forks, including a support plate. A stop is installed on the top of the support plate, and threaded holes are provided on the front, rear, and right end walls of the support plate. A through hole is provided on the end wall of the support plate near the threaded holes. Clamping mechanisms are installed on the front, rear, and right sides of the support plate. A central column is installed at the bottom of the support plate, and an inner rod passes through the interior of the central column. A screw passes through the front end wall of the central column. This utility model fixes the support plate and the central column together, making them an integral unit. In use, rotating the central column and the inner rod allows for threaded transmission between them, causing the inner rod to move along the vertical direction of the central column. This changes the distance between the base plate at the bottom of the inner rod and the support plate at the top of the central column, adjusting the position of the support plate. This makes it more convenient to use. The plate holes on the end walls of the base plate are used for threaded bolts. The base plate is then assembled onto an automotive shift fork welding machine for assembly.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0024] Please see Figure 1-4 This utility model provides a fixture for machining automotive shift forks, including a mounting plate 1. A connecting disc 2 is bolted to the front of the mounting plate 1, and a mounting groove 101 is provided on the back of the mounting plate 1. A circular ring fixing member 6 is fixedly connected to the front of the connecting disc 2. A shift fork body 4 is clamped to the outside of the circular ring fixing member 6. The circular ring fixing member 6 includes a fixing post 601 fixedly connected to the connecting disc 2. Multiple limiting spring pieces 602 are fixedly connected in a ring at equal intervals around the axis of the fixing post 601 on the front of the connecting disc 2. Each limiting spring 602 has an arc-shaped guide spring 603 fixedly connected to its outer end. Each guide spring 603 is fixedly connected to the fixed post 601 via a reset spring 604 on the side facing the fixed post 601. The limiting spring 602 is C-shaped in general, and the contact point between the limiting spring 602 and the inner wall of the ring of the shift fork body 4 is horizontal. The ring fixing part 6 is an integrally cast structure. The ring fixing part 6 includes a fixed post 601 fixedly connected to the connecting plate 2.

[0025] The fixing post 601 serves as the central support component of the annular fixing member 6, playing a connecting and positioning role. Centered on the axis of the fixing post 601, multiple limiting spring pieces 602 are fixedly connected at equal intervals in a ring on the front side of the connecting plate 2. The limiting spring pieces 602 are generally "C"-shaped, and their contact points with the inner wall of the annular part of the shift fork body 4 are horizontal. This design allows the limiting spring pieces 602 to better fit with the annular part of the shift fork body 4, improving the clamping stability. Each limiting spring piece 602 has an arc-shaped guide spring piece 603 fixedly connected to its outer end. The design of the guide spring piece 603 allows the annular part of the shift fork body 4 to smoothly enter the limiting spring piece when clamping the shift fork body 4. Between 602, a certain amount of elastic support is provided to accommodate shift fork bodies 4 of different diameters. Each guide spring 603 is fixedly connected to the fixed post 601 on the side facing the fixed post 601 through a reset spring 604. The reset spring 604 is set so that when the annular part of the shift fork body 4 is subjected to external force during clamping, the guide spring 603 and the limiting spring 602 can undergo elastic deformation to absorb part of the impact force and return to the original state after the external force disappears, ensuring the stability and reliability of clamping. The annular fixing part 6 is an integrally cast structure with high strength and stability, and can withstand a large clamping force, ensuring the stability of the shift fork body 4 during processing.

[0026] When using this fixture, first fix the mounting groove 101 on the back of the mounting plate 1 to the welding machine or other processing equipment. Then, align the ring part of the shift fork body 4 with the entrance of the ring fixing piece 6 and slowly push it in so that the ring part of the shift fork body 4 contacts the limiting spring 602 and the guide spring 603 and undergoes elastic deformation. As the shift fork body 4 continues to be pushed in, the limiting spring 602 and the guide spring 603 gradually return to their original state under the action of the reset spring 604, tightly clamping the ring part of the shift fork body 4.

[0027] By incorporating components such as the circular fixing element 6, the limiting spring 602, and the guide spring 603, this clamp can adapt to shift fork bodies 4 of different shapes and sizes, thus improving the clamp's adaptability and practicality. The circular fixing element 6 is an integrally cast structure with high strength and stability. Meanwhile, the limiting spring 602, the guide spring 603, and the reset spring 604 enable the clamp to undergo elastic deformation when holding the shift fork body 4, absorbing some of the impact force and returning to its original state after the external force disappears, ensuring the stability and reliability of the clamping.

[0028] In this embodiment, the mounting plate 1 is provided with two V-shaped fixing brackets 3 located below the annular fixing member 6. A limiting roller 8, which is in contact with the inner wall of the shift fork body 4 bracket, is slidably connected inside the fixing bracket 3. A guide post 5 is fixedly connected inside the fixing bracket 3, and a sliding block 7 is slidably connected outside the guide post 5. The limiting roller 8 is fixedly connected to the front of the sliding block 7. A spring is fixedly connected to the top of the sliding block 7 and one end of the guide post 5. The spring is sleeved outside the guide post 5, and the front of the fixing bracket 3 is in contact with the back of the shift fork body 4 bracket. A limiting block 9 is fixedly connected to the front of the mounting plate 1, and the top of the limiting block 9 is in contact with the top of the inner cavity of the shift fork body 4 bracket. A cavity is opened inside the limiting block 9. First, the annular portion of the shift fork body 4 is initially positioned and fixed by the annular fixing member 6. At this time, the bracket portion of the shift fork body 4 is suspended, ready for further... According to the shape and size of the shift fork body 4 bracket, the operator needs to manually adjust the position of the sliding block 7 on the guide post 5. Due to the presence of the spring, the sliding block 7 and the limiting roller 8 can move freely within a certain range and automatically reset. This allows the limiting roller 8 to fit against the inner wall of the shift fork body 4 bracket. When the limiting roller 8 is adjusted to the appropriate position, they will fit tightly against the inner wall of the shift fork body 4 bracket. At this time, the front of the fixing frame 3 fits against the back of the shift fork body 4 bracket, forming a clamping of the shift fork body 4 bracket. At the same time, the top of the limiting block 9 fits against the top of the inner cavity of the shift fork body 4 bracket, further restricting the movement of the shift fork body 4 in the vertical direction. After the shift fork body 4 is stably clamped, processing equipment such as welding machines can be started to process the shift fork body 4. Due to the stability and adaptability of the fixture, the processing will be more accurate and efficient.

[0029] By setting the fixed frame 3 and the limiting roller 8, the clamp can more stably hold the support part of the shift fork body 4. The sliding adjustment of the limiting roller 8 and the automatic reset function of the spring enable the clamp to adapt to shift fork bodies 4 of different shapes and sizes, improving the stability and adaptability of the clamp. Due to the stability and adaptability of the clamp, the shift fork body 4 will maintain a more stable posture during the processing, which helps to reduce processing errors and improve processing accuracy and quality. The operator only needs to manually adjust the position of the sliding block 7 to clamp the shift fork body 4. This simple operation process reduces the difficulty of operation and improves work efficiency.

[0030] The working principle and usage process of this utility model are as follows: First, the mounting groove 101 on the back of the mounting plate 1 is fixedly connected to a welding machine or other processing equipment. Then, the annular part of the shift fork body 4 is aligned with the inlet of the annular fixing member 6 and slowly pushed in, so that the annular part of the shift fork body 4 contacts the limiting spring 602 and the guide spring 603 and undergoes elastic deformation. As the shift fork body 4 continues to be pushed in, the limiting spring 602 and the guide spring 603 gradually return to their original state under the action of the reset spring 604, tightly clamping the annular part of the shift fork body 4. The annular part of the shift fork body 4 is initially positioned and fixed by the annular fixing member 6. At this time, the support part of the shift fork body 4 is suspended in the air, ready for further clamping. According to the shape and size of the support of the shift fork body 4, the operator needs to... The position of the sliding block 7 on the guide post 5 is manually adjusted. Due to the presence of the spring, the sliding block 7 and the limiting roller 8 can move freely within a certain range and automatically reset. This allows the limiting roller 8 to fit against the inner wall of the shift fork body 4 bracket. When the limiting roller 8 is adjusted to the appropriate position, they will fit tightly against the inner wall of the shift fork body 4 bracket. At this time, the front of the fixing frame 3 fits against the back of the shift fork body 4 bracket, forming a clamping of the shift fork body 4 bracket. At the same time, the top of the limiting block 9 fits against the top of the inner cavity of the shift fork body 4 bracket, further restricting the movement of the shift fork body 4 in the vertical direction. After the shift fork body 4 is stably clamped, processing equipment such as welding machines can be started to process the shift fork body 4. Due to the stability and adaptability of the fixture, the processing will be more accurate and efficient.
