A receiving element 11 is clamped on the positioning component. A reading head is installed on the receiving element 11. The code disk 5 and the receiving element 11 form an encoder. An information line 12 is installed on the receiving element 11; during operation, in the process of testing the encoder by the existing test tooling, in order to facilitate the assembly of the code disk 5 during the assembly of the code disk 5, the code disk 5 is clamped, but the stability of the code disk 5 cannot be guaranteed, resulting in poor stability of the assembly of the code disk 5. By placing the code disk 5 in the clamping groove 4 of the rotating seat 3 and rotating the first knob 8, the first lead screw 7 is driven to rotate. The first lead screw 7 drives the two sliders 9 thereon to move synchronously in opposite directions. The two sliders 9 drive the two clamping blocks 10 to move synchronously in opposite directions. The two clamping blocks 10 clamp and fix the inner ring of the code disk 5, so that the code disk 5 is fixedly connected to the rotating seat 3, realizing the stable placement of the code disk 5; then the receiving element 11 is placed on the positioning groove 19. By rotating the third knob 22, the third lead screw 21 is driven to rotate. The third lead screw 21 drives the second moving block 23 to move horizontally. The second moving block 23 drives the positioning block 24 to move horizontally. The positioning block 24 and the positioning seat 18 cooperate to clamp and fix the receiving element 11;

[0020] After that, the operation of the motor 2 is controlled through the control panel 26. The motor 2 drives the rotating seat 3 to rotate. The rotating seat 3 drives the code disk 5 to rotate. The receiving element 11 reads the rotation angle of the code disk 5 and sends the detection signal to the control panel 26. The numerical value of the output signal of the encoder can be directly obtained from the control panel 26, realizing the test of the encoder. This structure can stably place the code disk 5, which is beneficial to improving the stability of the assembly of the code disk 5 and is beneficial to improving the test accuracy.

[0021] Please refer to Figures 4-5As shown, a distance adjustment component is installed on the base 1. The distance adjustment component includes a guide plate 13. A first moving groove 14 is formed in the guide plate 13. A second lead screw 15 is rotatably installed on the inner wall of the first moving groove 14. One end of the second lead screw 15 is welded with a second knob 16. A first moving block 17 is assembled in the first moving groove 14. A positioning seat 18 is installed on the first moving block 17. A positioning groove 19 is formed in the positioning seat 18. A second moving groove 20 is formed in the positioning seat 18. A third lead screw 21 is rotatably installed in the second moving groove 20. One side of the third lead screw 21 is welded with a third knob 22. A second moving block 23 is assembled in the second moving groove 20. A positioning block 24 is installed on the second moving block 23. A debugging plate 25 is installed on the base 1. Jacks are arranged on the debugging plate 25. The debugging plate 25 is connected to the information line 12 through the jacks. A control panel 26 is connected to the debugging plate 25 through a data line. A support platform 27 is installed on the base 1. The support platform 27 is fixedly connected to the control panel 26. During operation, in the existing test fixture, due to the fixed position between the assembly structures of the code disk 5 and the receiving element 11, the distance between the code disk 5 and the receiving element 11 cannot be adjusted, and the influence of the position error between the receiving element 11 and the code disk 5 on the overall performance of the encoder cannot be tested, resulting in a poor test effect. By rotating the second knob 16, the second lead screw 15 is driven to rotate. The second lead screw 15 drives the first moving block 17 to move horizontally. The first moving block 17 drives the positioning seat 18 to move horizontally. The positioning seat 18 drives the receiving element 11 clamped thereon to move horizontally, realizing the distance adjustment between the code disk 5 and the receiving element 11. By adjusting the distance between the code disk 5 and the receiving element 11, the influence of the position error between the receiving element 11 and the code disk 5 on the overall performance of the encoder is tested, which is beneficial to improving the test effect.

[0022] Working principle: During the testing of the encoder by the existing test tooling, in order to facilitate the assembly of the code disk 5, the code disk 5 is snap-connected during assembly, but the stability of the code disk 5 cannot be guaranteed, resulting in poor stability of the assembly of the code disk 5. By placing the code disk 5 in the card slot 4 of the rotating seat 3, rotating the first knob 8 drives the first lead screw 7 to rotate. The first lead screw 7 drives the two sliders 9 on it to move synchronously in opposite directions. The two sliders 9 drive the two clamping blocks 10 to move synchronously in opposite directions. The two clamping blocks 10 clamp and fix the inner ring of the code disk 5, so that the code disk 5 is fixedly connected to the rotating seat 3, realizing the stable placement of the code disk 5. Then, the receiving element 11 is placed on the positioning groove 19. By rotating the third knob 22, the third lead screw 21 is driven to rotate. The third lead screw 21 drives the second moving block 23 to move horizontally. The second moving block 23 drives the positioning block 24 to move horizontally. The positioning block 24 and the positioning seat 18 cooperate to clamp and fix the receiving element 11. Then, the motor 2 is controlled by the control panel 26 to operate. The motor 2 drives the rotating seat 3 to rotate. The rotating seat 3 drives the code disk 5 to rotate. The receiving element 11 reads the rotation angle of the code disk 5 and sends the detection signal to the control panel 26. The value of the encoder output signal can be directly obtained from the control panel 26, realizing the testing of the encoder. This structure can stably place the code disk 5, which is beneficial to improving the stability of the assembly of the code disk 5 and the testing accuracy. Due to the fixed position between the assembly structures of the code disk 5 and the receiving element 11 in the existing test tooling, the distance between the code disk 5 and the receiving element 11 cannot be adjusted, and the influence of the position error between the receiving element 11 and the code disk 5 on the overall performance of the encoder cannot be tested, resulting in poor testing effects. By rotating the second knob 16, the second lead screw 15 is driven to rotate. The second lead screw 15 drives the first moving block 17 to move horizontally. The first moving block 17 drives the positioning seat 18 to move horizontally. The positioning seat 18 drives the clamped receiving element 11 to move horizontally, realizing the adjustment of the distance between the code disk 5 and the receiving element 11. By adjusting the distance between the code disk 5 and the receiving element 11, the influence of the position error between the receiving element 11 and the code disk 5 on the overall performance of the encoder is tested, which is beneficial to improving the testing effects.
