Three-coordinate image measuring instrument platform vertical fine adjustment device and implementation method thereof

Abstract

The invention discloses a three-coordinate image measuring instrument platform vertical fine adjustment device which comprises a base, a table top is arranged above the base, the base and the table top are connected through three adjusting assemblies, the three adjusting assemblies are distributed in an annular array, and tensioning guide sleeve assemblies are arranged on the two sides of each adjusting assembly respectively. The invention further discloses an implementation method of the three-coordinate image measuring instrument platform vertical fine adjustment device. According to the principle that a plane is determined by three points, the table board is adjusted through the three adjusting assemblies, so that vertical adjustment of key measuring positions of a measured workpiece is achieved, and the measuring instrument achieves accurate measurement under ideal conditions; two of the three adjusting assemblies are the lifting assemblies, the other adjusting assembly is the fixing assembly, vertical adjustment of the table top is achieved through the two lifting assemblies, and the production cost of the lifting table is reduced.

Description

technical field

[0001] The invention belongs to the technical field of measuring instrument platform adjustment, and in particular relates to a vertical fine-tuning device for a three-coordinate image measuring instrument platform and an implementation method thereof. Background technique

[0002] In recent years, with the development and progress of science and technology, the requirements for detection accuracy and measurement speed of geometric quantities (such as length, angle, etc.) in various fields have been continuously improved, which largely depends on the development of measuring instruments and detection method improvement. In the past few decades, the detection methods of classical geometric dimensions and shape parameters have become increasingly mature, the most typical of which is the three-coordinate measuring machine.

[0003] However, the conventional three-coordinate measuring machine is equipped with a contact probe. Although it can achieve high detecti...
