[0002] The optical module clamping fixture is a fixture tool used to fix the optical module on the processing equipment. The optical module refers to the components or parts used in the optical system, such as lenses, reflectors, filters, etc. During the processing, in order to ensure the accuracy and stability of the optical module, it is usually necessary to use a clamping fixture to fix the optical module to prevent it from moving or deforming during the processing. The clamping fixture usually has an adjustable clamping force and clamping position to ensure that the position and angle of the optical module meet the requirements. By using a clamping fixture for optical module processing, the processing accuracy and efficiency can be improved, and the quality and performance of the optical module can be ensured.
