Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of clamping devices, in particular to a sensor housing clamping device for sensor assembly. Background Art
[0002] The sensor housing is the external structure that holds the various components of the sensor together and protects them from the external environment. The housing is usually made of metal, plastic or other materials, and has properties such as corrosion resistance, waterproofness, and high temperature resistance. The design and manufacture of the sensor housing is critical to the performance and reliability of the sensor.
[0003] During the assembly process of the sensor, its shell needs to be clamped and displaced using a clamping device. The conventional clamping structure uses pneumatic or motor-driven methods to control two clamping plates for clamping. However, the clamping force is difficult to control. When the force is too large, the sensor shell will be damaged. When the force is too small, the sensor shell will fall off when moving. Therefore, a sensor shell clamping device for sensor assembly is proposed. Utility Model Content

A bottom plate 11 is arranged at the lower end of the side shell 10, and an electromagnet 12 is installed on one side of the lower end of the bottom plate 11. A telescope 16 is installed on one side inside the electromagnet 12, and a first return spring 17 is installed on the outside of the telescope 16. A hook plate 13 is fixedly installed on one end of the outside of the telescope 16, and a sponge pad 14 is adhesively fixed on the side of the outside of the hook plate 13 away from the electromagnet 12, and the thread grooves of the two driving screws 4 are opposite.
