[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 and Figure 2 The present invention provides an embodiment of a magnetic anti-misoperation device for a gearbox shift fork, comprising a base plate 1, which is the foundation of the anti-misoperation device. All components are installed on the top of the base plate 1. A fixed base 2 is fixedly connected to the top of the base plate 1. A marking sleeve 4 is fixedly connected to one side of the fixed base 2. The fixed base 2 supports the marking sleeve 4. The main structure of the anti-misoperation device is installed inside the marking sleeve 4. A sliding component and a spring-loaded component are installed inside the marking sleeve 4.

[0033] The sliding component includes a slider 9, which is slidably connected inside the marking sleeve 4. The slider 9 can move and change position inside the marking sleeve 4. A groove 10 is provided inside the marking sleeve 4, and the slider 9 is located inside the groove 10. The groove 10 can support the movement of the slider 9 and also limit the range of movement of the slider 9. By providing a groove 10 inside the marking sleeve 4, the slider 9 and other components can move inside the marking sleeve 4 to achieve the marking work.

[0034] Reference Figure 3The rebound assembly includes a needle 5, which is slidably connected inside the marking sleeve 4. Moving one end of the needle 5 inside the marking sleeve 4 marks the position fork by moving it outwards. A spring 6 is sleeved on the outside of the needle 5, allowing the needle 5 to return to its original position after movement, facilitating continuous testing. The needle 5 is fixedly connected to one side of the slider 9. When the slider 9 moves inside the groove 10, it moves the needle 5, allowing it to move in and out of one end of the marking sleeve 4 to mark the position fork. The spring 6 is located inside the marking sleeve 4, with one end abutting against one side of the slider 9. When the slider 9 moves, the spring 6 is squeezed between the slider 9 and the marking sleeve 4, causing the slider 9 to rebound. The fixed base 2 has an air inlet 3 inside, which is used to deliver compressed gas. The air inlet 3 is located at one end of the marking sleeve 4. The air inlet 3 delivers compressed gas into the marking sleeve 4, causing the compressed gas to push the slider 9 to move, thereby driving the needle 5 to move outward to mark the shift fork. The movement of the needle 5 is achieved by the slider 9 and the slide groove 10, which is convenient for marking. The spring 6 allows the needle 5 to return to its original position after movement, and it is driven by compressed air, which is convenient for use.

[0035] Reference Figures 1-3 A stop block 7 is fixedly connected to the top of the base plate 1. The stop block 7 is located in front of the needle 5 and is used to fix the shift fork to prevent it from moving. A working area 8 is set on the top of the base plate 1. The working area 8 is located on one side of the stop block 7. The shift fork can be placed on the working area 8 for marking work. Two fixing screws 11 are internally threaded to the fixed base 2. The two fixing screws 11 are located on both sides of the top of the fixed base 2. The fixed base 2 is fixed to the top of the base plate 1 with the two fixing screws 11. It can be disassembled for easy transportation. Two fixing screws 12 are internally threaded to the stop block 7. The two fixing screws 12 are located on both sides of the top of the stop block 7. The stop block 7 is fixed with the fixing screws 12, allowing the stop block 7 to be disassembled.

[0036] Working principle: First, the robotic arm places the shift fork on the working area 8 of the magnetic error prevention device. A compressed air pipe is connected to the air inlet 3. The compressed air enters the marking sleeve 4 through the air inlet 3. Under the action of the sliding groove 10 inside the marking sleeve 4, the compressed air creates pressure in the inner cavity of the marking sleeve 4, which pushes the slider 9 to move inside the sliding groove 10. The movement of the sliding groove 10 drives the needle 5 on one side to move, allowing the needle 5 to move quickly inside the sliding groove 10 of the marking sleeve 4. The needle 5 is then ejected. Under the action of the stop block 7, the needle 5 marks the shift fork, engraving a physical mark on the shift fork.

[0037] Secondly, after the marking work is completed, when the needle 5 pops out, it will cause the slider 9 to squeeze the spring 6. The spring 6 is squeezed and exerts a reverse force on the needle 5 and the slider 9 through its own elasticity, causing the slider 9 to bounce back inside the slide groove 10 and retract the needle 5 into the marking sleeve 4, thus completing the magnetic anti-error process of the shift fork.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
