Abstract

The invention relates to the technical field of workpiece detection, and especially relates to a workpiece detection auxiliary device, comprising a mounting rack arranged at a light output end of a laser generator, a lens arranged on the mounting rack, and an adjusting sheet which is deformable and arranged between the lens and the laser generator, wherein an adjusting cavity filled with adjustingliquid is formed between the lens and the adjusting sheet, the adjusting sheet is provided with a magnetic piece having magnetism, and the lens is provided with an electromagnet. The workpiece detection auxiliary device of the invention can assist a detection laser beam to perform divergence or convergence in different degrees, so as to be adapted to measurement of different workpieces.

Description

technical field [0001] The invention relates to the technical field of workpiece detection, in particular to an auxiliary device for workpiece detection. Background technique [0002] At present, laser is used in many fields such as scientific research and industry, and is a commonly used tool in detection. In laser scanning, interferometry or telemetry applications, it is often necessary to use a laser beam with a larger diameter; and in the measurement of some small workpieces, if the laser spot is too large, it may exceed the size that the beam quality analysis equipment can measure range, so a smaller laser beam is required. The general laser beam expander or beam reducer mostly has a fixed expansion or reduction rate, which is poor in versatility and inconvenient to use. Therefore, there is a need for an auxiliary device that can assist the laser beam to diverge or converge to different degrees. Contents of the invention [0003] The present invention aims to solve...
