Abstract

The invention provides a micro-force measuring type three-dimensional comprehensive thread measuring machine measuring head and a measuring method thereof, which can simply and accurately measure thedisplacement of a probe so as to measure the spatial position of a measured thread. The micro displacements of the probe in the horizontal direction and the vertical direction are respectively measured through the transverse micro displacement measuring system and the longitudinal micro displacement measuring system. After the probe is in pre-contact with a measured thread and is driven by the three-dimensional comprehensive thread measuring machine, the probe respectively displaces in the horizontal direction and the vertical direction, the two groups of parallel reeds are used as guide mechanisms and are respectively stretched, the reading head of the linear grating system and the long grating relatively displace, and the displacement is measured. The measuring head is used for thread detection of the micro-force force measurement type three-dimensional comprehensive thread measuring machine.

Description

technical field [0001] The invention relates to the field of measurement technology, in particular to a measuring head used for measurement. Background technique [0002] Thread is an important basic part in the field of industrial manufacturing. It is used for fastening connection or transmission. Since the thread has complex spiral grooves with different angle shapes, it is difficult to accurately measure its geometric shape and parameter information, resulting in many details in the thread manufacturing process. It cannot be controlled and seriously affects the thread quality level. In order to detect the real and comprehensive three-dimensional shape and thread parameters of the thread, the development of three-dimensional thread measurement equipment will greatly promote the thread manufacturing. [0003] The three-dimensional comprehensive thread measuring machine can realize the three-dimensional measurement of the thread by selecting the cylindrical coordinate syste...
