Image capturing device for detecting and analyzing machine tool guiderail surface quality

Abstract

Provided is an image capturing device for detecting and analyzing a machine tool guiderail surface quality. The image capturing device mainly comprises a mobile box body, a sliding assembly, a rotating assembly, and a capturing assembly. The mobile box body is mainly composed of an inner guiderail sleeve 1, an outer box body 2, a hand wheel 3, and a built-in friction wheel 4. The sliding assembly is mainly composed of a handle 5, a sliding body 6, a lead screw 7, and a mobile table 8. The rotating assembly is mainly composed of a rotating pedestal 9, a worm 21, a rotating platform 10, and a fixing block 11. The capturing assembly is connected with the fixing block 11 through a V-shaped rod 12 and mainly comprises a sliding rod 19, an ocular lens moving device 14, a U-shaped support 15, a connector 16, an ocular lens 17, a mobile square block 18, and a light device 20. The image capturing device is simple in structure and low in production cost. By the replacement of the inner guiderail sleeve, the images of large machine tool guiderail surfaces with different cross sections can be fast and accurately acquired. The image capturing device provides image support for guiderail surface wearing state identification based on machine vision detection technology, provides decision basis for taking effective measures to relieve wearing or repair the guiderail, has important significance to maintenance of machine tool precision and guarantee of product quality, and can be widely used in the field of machine tool guiderail surface quality detection.

Description

technical field [0001] The invention relates to the field of quality detection of machine tool guide rails, in particular to an image capturing device for detecting and analyzing the quality of machine tool guide rails. Background technique [0002] The accuracy of the guide rail of the machine bed directly affects the size, shape and position error of the machined parts. Therefore, whether it can maintain high-precision machining status will affect the product qualification rate and the service life of the machine tool. Therefore, the accuracy of the guide rail of the machine tool Testing is critical. Since the guide rails of the bed are exposed to the air all the year round and are not protected, the dust-proof and chip-proof conditions are poor, and wear will inevitably occur after long-term use. When the wear is serious, the machining accuracy of the parts will not meet the requirements, and even cause The guide rail fails, so wear is the root cause of the decline in th...
