Through this arrangement, the support rod 61 can be mounted on the mounting base 21 via a threaded rod 69. The threaded rod 69 is then limited by a limit nut 62, making the installation of the support rod 61 more stable and allowing the height of the top of the support rod 61 to be adjusted. The proximity switch 65 can then be installed in the mounting slot 68 provided in the switch bracket 63 using the clamping nut 67. At this point, the proximity switch 65 can be fine-tuned by adjusting it up and down to accommodate different specifications and models of the divider body 4.

[0030] Working process: When using this device for detecting the accuracy of the rotary angle of the divider, the base 1 is usually placed directly in the appropriate position, and then the divider body 4 is placed on the mounting base 21, and then the screws are passed through the mounting base 21 and threadedly connected to the divider body 4 to fix the divider body 4, and then a suitable number of pads 261 and rubber pads 262 are selected, and the connecting block 266 provided on the pad 261 is inserted into the limiting groove 264 provided on the motor seat 23. At this time, the connecting block 266 pushes the rubber block 267 to deform under the action of the deformation groove 268 provided by itself, until the top of the pad 261 and the motor seat 23 fit each other, and at this time, the rubber block 267 fits tightly with the connecting block 266 under the action of its own elastic force, and then install it below. His pad 261, after the pad 261 is installed, the rubber pad 262 is installed on the lower side of the pad 261, and the rubber pad 262 is inserted into the limiting groove 264 opened at the bottom of the fixing frame 263 through the connecting block 266 fixedly connected to the top of the fixing frame 263, and is also positioned by the rubber block 267. Then another rubber plate 28 is installed at the bottom of the first rubber plate 28. At this time, the connecting block 266 is inserted into the clamping groove 265 opened by the rubber plate 28 to install the two rubber plates 28. Then the rubber plate 28 and the pad 261 are placed in the fixing groove 22 opened on the installation base 21, and then the motor seat 23 is moved to align the output shaft of the stepper motor 3 with the input shaft set by the divider body 4, and the second bolt 25 is passed through the motor seat 23 and the pad 261, fixing frame 263 and rubber pad 262, then put the rubber plate 28 and clamping plate 27 on the outside of the second bolt 25, rotate the second bolt 25, so that the second bolt 25 is threadedly connected with the mounting nut 29, and at this time the clamping plate 27 pushes the rubber plate 28 to fit tightly with the bottom of the mounting base 21 to achieve the positioning of the motor seat 23, and at this time continue to rotate the second bolt 25, the second bolt 25 drives the motor seat 23 and the pad 261 to move downward, and at this time pushes the rubber pad 262 to deform, thereby fine-tuning the height of the motor seat 23, so that the output shaft of the stepper motor 3 is aligned with the input shaft of the divider body 4, and then the coupling 5 is installed on the outside of the output shaft of the stepper motor 3 and the input shaft of the divider body 4 by screws, and then through the support rod 6 1 drives the threaded rod 69 to be threadedly connected to the mounting base 21. After the top of the support rod 61 is adjusted to the appropriate height, the limiting nut 62 is rotated so that the bottom of the limiting nut 62 is tightly fitted with the mounting base 21 to position the threaded rod 69 and the support rod 61. Then, the switch is installed between the support rod 61 through the third bolt 64. The proximity switch 65 is passed through the mounting groove 68 opened in the switch bracket 63. The two clamping nuts 67 are rotated. The clamping nuts 67 are threadedly connected to the proximity switch 65. When the clamping nuts 67 are tightly fitted with the switch bracket 63, the proximity switch 65 is positioned. Then, the wire 66 is connected to the computer through the connector. Then, the computer is powered on. The computer is connected to the driver and the stepper motor 3 via the data cable.During the test, the number of pulses is set on the computer and driver, and the motor is driven by the number of pulses. The motor shaft and coupling 5 drive the input shaft of the divider body 4 to rotate, and finally the output shaft rotates at a low speed through the reduction gear. The output shaft of the divider body 4 drives the connecting plate 7 and the sensing screw 8. When rotating, it will periodically pass through the sensing area of ​​the proximity switch 65. The proximity switch 65 can capture the time from the first time the sensing screw 8 passes through the sensing area until the Nth time. The actual rotation angle of the output shaft at the Nth circle is exactly N*360°. When the number of pulses T sent by the computer and driver from the first to the Nth time is called, the actual rotation angle of the input shaft can be calculated. Then, divided by the reduction ratio of the divider body 4, the theoretical rotation angle of the output shaft can be obtained. Then, compared with the actual value, the error value can be used to determine whether the divider body 4 is within the parameter range.
