[0022] Reference Figure 1-4 This utility model discloses a fixture for producing automotive gearbox shift forks, comprising: a base plate 1, a telescopic rod 2 fixedly connected inside the base plate 1, a support plate 3 fixedly connected to the output end of the telescopic rod 2, a side end of the support plate 3 rotatably connected to the upper surface of the base plate 1, two telescopic rods 2 located at the front and rear ends of the support plate 3, a limit post 4 fixedly connected to the upper surface of the support plate 3, a shift fork 12 provided on the side surface of the limit post 4, a conical ring 13 threadedly connected to the top end of the limit post 4, a pressing plate 14 slidably connected to the side surface of the limit post 4, a spring 15 fixedly connected to the inner wall of the pressing plate 14, the end of the spring 15 away from the pressing plate 14 fixedly connected to the side surface of the limit post 4, a telescopic plate 5 fixedly connected to the upper surface of the support plate 3, a clamping plate 6 fixedly connected to the output end of the telescopic plate 5, and the end of the clamping plate 6 away from the telescopic rod 2 contacting the side surface of the shift fork 12.

[0023] Specifically, the shift fork 12 is placed on the surface of the support plate 3, so that the limiting post 4 passes through the slot of the shift fork 12. The activation of the telescopic rod 2 can push the support plate 3 to rotate on the upper surface of the base plate 1. The rotating cone ring 13 causes its lower surface to press against the pressing plate 14, so that the pressing plate 14 resists the elastic force of the spring 15 and slides against the inner wall of the slot of the shift fork 12, thus completing the fastening of the slot of the shift fork 12. The activation of the telescopic plate 5 pushes out the clamping plate 6, so that it clamps the neck of the shift fork 12 from both sides.

[0024] A lead screw 7 is provided at its end, and a motor 16 is fixedly connected to the inside of the support plate 3. A slider 8 is provided on the side surface of the lead screw 7 and is slidably connected to the inside of the support plate 3. An arc plate 9 is fixedly connected to the upper surface of the slider 8 and its side surface is fitted with a shift fork 12.

A slide frame 11 is slidably connected to the side surface of the slide plate 10 and is fixedly connected to the inside of the support plate 3.

[0025] Specifically, the starter motor 16 can rotate the lead screw 7 to drive the slider 8 on its surface to slide inside the support plate 3, so that the slider 8 drives the arc plate 9 on its upper surface to move. The arc plate 9 fits against the shift fork 12 to clamp the working end of the shift fork 12. A slide plate 10 is provided on the side surface of the slider 8 to slide inside the slide frame 11, so that it can block the chips generated by the shift fork 12 and prevent the chips from falling into places that are not easy to clean, so that the workers can easily clean the chips.

[0026] Working principle: During the use of the device, the shift fork 12 is placed on the surface of the support plate 3, so that the limiting post 4 passes through the slot of the shift fork 12. Activating the telescopic rod 2 pushes the support plate 3 to rotate on the upper surface of the base plate 1. The rotating cone ring 13 causes its lower surface to press against the pressing plate 14, making the pressing plate 14 slide against the elastic force of the spring 15, and press against the inner wall of the slot of the shift fork 12, thus completing the fastening of the slot of the shift fork 12. Activating the telescopic plate 5 pushes out the clamping plate 6, so that it faces the shift fork 12 from both sides. The neck of the 2 is clamped, and the starting motor 16 can rotate the lead screw 7 to drive the slider 8 on its surface to slide inside the support plate 3, so that the slider 8 drives the arc plate 9 on its upper surface to move. The arc plate 9 fits against the shift fork 12 to complete the clamping of the working end of the shift fork 12. A sliding plate 10 is provided on the side surface of the slider 8 to slide inside the slide frame 11, so that it can block the chips generated by the shift fork 12 and prevent the chips from falling into places that are not easy to clean, so that the workers can easily clean the chips.
