It is a commonly used detection device in screw processing and is applied to various screw processing occasions. When in use, the existing screw processing accuracy detection device mainly detects the screw by moving the micrometer. However, the device does not have a moving structure, so it needs to be installed in conjunction with the guide rail of the processing equipment or other moving parts to cooperate with the detection, which makes it inconvenient to use long-distance detection of many screws. At the same time, when the micrometer contacts the screw, it can only perform contact detection in one direction, while the screw requires all-round detection, which also makes some positions unable to be detected, making it inconvenient to use the screw.
