Abstract

The invention provides a measuring head of a three-dimensional comprehensive thread measuring machine with micro-force force measurement and a measuring method thereof, which can simply and accurately measure the displacement of the probe, thereby measuring the spatial position of the measured thread. The micro-displacement of the probe in the horizontal and vertical directions is respectively measured by the transverse micro-displacement system and the longitudinal micro-displacement system. The probe is pre-contacted with the thread to be measured. After the three-dimensional comprehensive thread measuring machine is driven, the probe is displaced in the horizontal and vertical directions respectively. Two sets of parallel reeds are used as the guiding mechanism and are respectively stretched. The relative displacement of the grating occurs, and the displacement is measured. The invention is used for thread detection by a three-dimensional comprehensive thread measuring machine of micro force measuring type.

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...
