System for measuring inner diameter of rotator workpiece

Abstract

The invention discloses a system for measuring the inner diameter of a rotator workpiece. The system comprises a supporting assembly and a measuring assembly arranged on the supporting assembly. The base, the supporting part and the mounting part which are fixedly connected in sequence from bottom to top are used for forming the supporting frame, and parts for measurement are mounted; a rotary workbench is arranged on the base, and the rotator workpiece is fixed through a fixing part on the rotator workbench; a rotation angle grating is arranged in a rotary workbench to measure the rotation angle of the measured rotator workpiece; a Z-direction main shaft is arranged on a guide rail of a mounting part and forms two-axis measurement with a rotating shaft of the rotary workbench; a camera isarranged on the mounting part to detect whether a workpiece is placed on the rotary workbench or not; a displacement grating is arranged on the mounting part to measure the movement displacement of the Z-direction main shaft; a pneumatic displacement sensor is arranged at the bottom end of the Z-direction main shaft, high-pressure gas is injected into an air bag of the Z-direction main shaft, a probe is blown out, and the relative distance to a measured surface of the inner wall of the workpiece is measured; two-axis measurement of the inner diameter of the revolving body workpiece is realized.

Description

technical field [0001] The present disclosure generally relates to the technical field of measuring a rotary workpiece, and in particular to a system for measuring the inner diameter of a rotary workpiece. Background technique [0002] In the quality inspection of the production process of the rotary workpiece, the three-coordinate measuring machine is the main inspection method. Although the three-coordinate measuring machine has high measurement accuracy, due to its specific measurement method, the measurement efficiency of the system is low, which cannot meet the real-time measurement requirements on site; and due to the expensive price of the three-coordinate measuring machine and strict operating environment conditions Requirements make it difficult to be widely used and meet the requirements of modern production; at present, in mass industrial production, manual measurement is generally used to ensure the manufacturing and processing accuracy of rotary workpieces, and ...

Problems solved by technology

Although the three-coordinate measuring machine has high measurement accuracy, due to its specific measurement method, the measurement efficiency of the system is low, which cannot meet the real-time measurement requirements on site; and due to the expensive price of the three-coordinate measuring machine and strict operating environment conditions Requirements make it difficult to be widely used and meet the requirements of modern production; at present, in mass industrial production, manual measurement is generally used to ensure the manufacturing and processing accuracy of rotary workpieces, and the manual measurement method is very inefficient and difficult Meet the requirements of modern production

[0003] Therefore, we propose a system for measuring the inner diameter of rotating workpieces to solve the problems of the above-mentioned three-coordinate measuring machine, which are expensive, require high use environments, have low measurement efficiency, and introduce many errors.
