Abstract

The invention belongs to the measuring technology, and relates to a combined detection fixture for a three-coordinate measuring machine. The fixture is characterized in that the combined detection fixture is composed of a bottom plate (1), three basic parts and locking screws, and the three basic parts include a connection positioning column (3), a pressing block (4) and a positioning plate (5). The combined detection fixture for the three-coordinate measuring machine improves universality, shortens a measuring cycle, improves measuring efficiency and lowers measuring cost.

Description

technical field [0001] The invention belongs to the measurement technology, and relates to a combined inspection fixture for a three-coordinate measuring machine. Background technique [0002] The inspection fixture used by the existing three-coordinate measuring machine is a standard gauge block, which is used to locate the measured part. Its disadvantages are: the weight of the standard gauge block is large, the positioning surface is flat, and the adaptability is poor. For parts with different shapes, standard gauge blocks are not universal, and special measuring fixtures need to be designed and manufactured according to the structure of the parts to be measured, resulting in long measurement cycles, low efficiency, and high cost. Contents of the invention [0003] The object of the present invention is: to propose a combined inspection fixture for three-coordinate measuring machine, so as to improve the versatility of the inspection fixture, shorten the measurement pe...
