Abstract

An image capture device used for quality detection and analysis of machine tool guide rail surface. It mainly includes a moving box, a sliding component, a rotating component and a shooting component. The mobile box is mainly composed of an inner guide rail cover 1, an outer box 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 screw 7, and a mobile table 8 The rotating assembly is mainly composed of a rotating base 9, a worm 21, a rotating platform 10, and a fixed block 11. The shooting assembly is connected with the fixed block 11 through a V-shaped rod 12, and mainly includes a sliding rod 19, an eyepiece moving device 14 , U-shaped bracket 15, connector 16, eyepiece 17, moving square block 18, and lighting device 20. It has a simple structure and low manufacturing cost. By replacing the inner guide rail sleeve, images of the guide rail surface of large-scale machine tools with different sections can be quickly and accurately obtained, providing image support for the identification of the wear state of the guide rail surface based on machine vision inspection technology, and finally being able to take effective measures. Mitigate wear or repair rails to provide decision basis. It is of great significance to the maintenance of machine tool precision and product quality assurance, and can be widely used in the field of quality inspection of machine tool guide rail surfaces.

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 without protection, the dustproof and chipproof 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 the acc...
