Description

Technical Field

[0001] The utility model relates to the technical field of encoders, in particular to a quick-release stepping motor magnetic encoder. Background Art

[0002] The stepper motor magnetic encoder is a device used for stepper motor position detection and control. It uses magnetic field changes to sense the motor's rotation angle and speed, thereby achieving precise control of the stepper motor. That is, when the stepper motor rotates, the magnetic sensing element will detect the magnetic field changes on the motor rotor and convert these changes into electrical signals. The signal processing circuit will process and analyze these signals to obtain information such as the motor's rotation angle, speed and direction.

[0003] During the use of the stepper motor, it is very important to regularly inspect and repair the stepper motor magnetic encoder, because during use, the magnetic encoder may be affected by environmental factors such as temperature, humidity, dust, etc., resulting in performance degradation or failure. In addition, the frequent start and stop of the stepper motor will also cause certain wear and impact on the magnetic encoder. The traditional stepper motor magnetic encoder is fixed by multiple screws. Although it can ensure the stability and reliability of the encoder, it brings some inconvenience when performing regular maintenance. That is, using multiple screws to fix the magnetic encoder means that these screws need to be loosened and tightened one by one during maintenance. In addition, the way the screws are fixed may cause slight displacement of the screws during the operation of the stepper motor, which may affect the accuracy and calibration of the magnetic encoder.

The connecting screw 21 located between one side of the embedded groove 16 and the vertical part of the paddle 8 is provided with a compression spring 22. Through the cooperation of the paddle 8, the block B19 and the compression spring 22, after the block A13 is inserted and installed in the slot A10, its block B19 is inserted into the slot B11 to limit the block A13. Two limiting rings 23 are fixedly installed on one end of the connecting pin shaft 7. The connecting pin shaft 7 located between the two limiting rings 23 is rotatably installed in the installation hole A12, and the other end of the connecting pin shaft 7 passes through the through hole on one side of the magnetic encoder 1 and is clamped with a retaining spring.
