[0027] Reference Figure 1-5This utility model provides a precision testing fixture for automated equipment accessories, comprising: a housing 1, a guide groove 2 on the upper surface of the housing 1, a guide block 3 slidably connected to the inner surface of the guide groove 2, a guide rail 4 fixedly connected to the upper surface of the guide block 3, a movable frame 5 slidably connected to the inner surface of the guide rail 4, a first screw 6 threadedly connected to the bottom of the movable frame 5, the outer surface of the first screw 6 rotatably connected to the guide rail 4, a lifting frame 7 slidably connected to the inner surface of the movable frame 5, a second screw 8 threadedly connected to the inner surface of the lifting frame 7, the outer surface of the second screw 8 rotatably connected to the movable frame 5, and a dial indicator 9 fixedly connected to the right end of the lifting frame 7.
[0028] An adjusting turntable 10 is rotatably connected to the inner surface of the housing 1. A limiting ring 24 is fixedly connected to the outer surface of the adjusting turntable 10. The outer surface of the limiting ring 24 is slidably connected to the housing 1. The limiting ring 24 can restrict the position of the adjusting turntable 10 and improve the stability of the adjusting turntable 10 when rotating. A gear ring 11 is fixedly connected to the lower surface of the adjusting turntable 10. A drive tooth 12 is meshed with the lower surface of the gear ring 11. An adjusting rod 13 is fixedly connected to the side surface of the drive tooth 12. A backstop mechanism is provided on the outside of the adjusting rod 13 to restrict the rotation of the adjusting rod 13 and prevent the adjusting turntable 10 from reversing and causing the clamping plate 17 to loosen. An adjusting groove 14 is provided on the adjusting turntable 10. An adjusting block 15 is slidably connected to the inner surface of the adjusting groove 14. A slider 16 is fixedly connected to the upper surface of the adjusting block 15. A sliding groove 23 is provided on the upper surface of the housing 1. The inner surface of the sliding groove 23 is slidably connected to the slider 16. A clamping plate 17 is fixedly connected to the upper surface of the slider 16.
[0029] The anti-reverse mechanism includes a first anti-reverse disc 18, a second anti-reverse disc 19, a lever 20, a spring 21, and a protective box 22. The outer surface of the adjusting rod 13 is fixedly connected to the first anti-reverse disc 18, the outer surface of the housing 1 is fixedly connected to the protective box 22, the outer surface of the adjusting rod 13 is rotatably connected to the protective box 22, the right inner wall of the protective box 22 is fixedly connected to the spring 21, and the left end of the spring 21 is fixedly connected to the second anti-reverse disc 19. Anti-reverse teeth 25 are provided on the side walls where the first anti-reverse disc 18 and the second anti-reverse disc 19 fit together. The two anti-reverse teeth 25 are in opposite directions to facilitate the adjustment of the first anti-reverse disc. The reverse rotation of the first check disc 18 is restricted, the check teeth 25 are engaged with each other, the inner surface of the second check disc 19 is slidably connected to the adjusting rod 13, and the outer surface of the second check disc 19 is fixedly connected to the lever 20. The lever 20 not only facilitates the adjustment of the position of the second check disc 19, but also restricts the rotation of the second check disc 19 to prevent the first check disc 18 from rotating and causing the second check disc 19 to rotate. The outer surface of the lever 20 is slidably connected to the protective box 22, the outer surface of the first check disc 18 is slidably connected to the protective box 22, and the outer surface of the second check disc 19 is slidably connected to the protective box 22.
[0030] Working principle: The part to be tested is placed on the housing 1. Rotating the adjusting rod 13 drives the driving gear 12 to rotate. Through the meshing connection between the driving gear 12 and the gear ring 11, the adjusting turntable 10 is rotated. The rotation of the adjusting turntable 10 causes the adjusting block 15 to slide along the adjusting groove 14, thereby causing the slider 16 to slide along the sliding groove 23 to adjust the position of the clamping plate 17, which facilitates clamping of the part. During the rotation of the adjusting rod 13, the first check plate 18 is rotated. Under the action of the spring 21, the second check plate 19 is kept in contact with the first check plate 18. The interaction of the check teeth 25 on the first check plate 18 and the second check plate 19 keeps the first check plate in contact with the check plate 18. The reverse rotation of 18 is restricted to prevent the clamping plate 17 from loosening due to the reverse rotation of the adjusting turntable 10. During testing, rotating the first screw 6 drives the moving frame 5 to move along the guide rail 4, and rotating the second screw 8 drives the lifting frame 7 to move up and down, thereby adjusting the height and position of the dial indicator 9. Pushing the guide rail 4 causes the guide block 3 to rotate along the guide groove 2, which facilitates the testing of different positions of the parts. After the test is completed, pushing the toggle block 20 separates the second check plate 19 from the first check plate 18, thereby removing the restriction on the first check plate 18. Then, the reverse adjustment rod 13 can be rotated to reverse the adjustment turntable 10, causing the clamping plate 17 to move and remove the clamping of the parts.

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.
