Description

Technical field:

[0001] The utility model relates to the technical field of gear induction quenching, in particular to a gap measuring device used for gear induction quenching processing. Background technology:

[0002] Before the gear is induction hardened along the tooth groove, it is necessary to first measure the gap between the sensor and the tooth surface and tooth root of the gear, and then adjust the sensor on the X-axis, Y-axis, and Z-axis through the sensor mounting seat until the sensor is at the center of the tooth groove and the distance between the sensor and the tooth surface and tooth root meets the set requirements, thereby ensuring the consistency of the quality of the gear after quenching. At present, the gap measurement between the sensor and the tooth surface and tooth root is completed by manual measurement, but manual measurement is time-consuming and inefficient, and due to different measurement capabilities, different measurement techniques, and measuring tool accuracy of personnel, the gap measurement will be inaccurate, resulting in unqualified workpiece processing. At present, it is impossible to monitor the actual value of the gap in the machine tool production process in real time, and it cannot be adjusted while quenching, and the production quality fluctuates greatly. Utility model content:
