Sliding guide rail plastic-pasting process method

Abstract

The invention belongs to the technical field of precision machining and testing, and relates to a sliding guide rail plastic-pasting process method, which comprises the following steps of: machining a high-flatness calibration plane by utilizing a three-plane mutual grinding method to grind and refine a guide rail base body, roughening the guide rail base body by utilizing a laser surface texture, and after the guide rail base body is subjected to plastic pasting, matching the laser surface texture with the calibration plane for grinding to refine a guide rail soft belt and machine an oil groove. The method can replace manual scraping to machine the guide rail base body and the guide rail soft belt, so that the machining efficiency is higher, the labor intensity is lower, and the precision consistency is better; the sliding guide rail can be subjected to high-precision plastic pasting machining without more scraping experience, so that the processing cost is lower; and complex oil grooves with different shapes and depths can be designed, so that flowing of lubricating oil and antifriction of the sliding guide rail are facilitated, the using performance of a sliding pair is improved, the service life of the sliding pair is prolonged, and the good market application prospect and popularization value are achieved.

Description

technical field [0001] The invention belongs to the field of precision machining and testing, and relates to a process method for pasting plastic on sliding guide rails. Background technique [0002] Guide rail is an indispensable part in the field of machining and testing. It is a track used to support and guide parts to move accurately along a certain track or play a role in clamping and positioning. The friction between the two guide rail surfaces is sliding friction, called sliding guide rail, which is one of the commonly used guide rail types for machine tools. It has the advantages of simple structure, easy manufacture, large bearing capacity and strong shock resistance. Its disadvantages are fast wear and poor precision retention; large frictional resistance and poor movement flexibility; large difference between dynamic and static friction coefficients, easy to "crawl" when heavy load or low-speed movement; easy to generate heat when high-speed movement, etc. In or...

Problems solved by technology

However, the scraping and grinding of high-precision guide rails on the market and the scraping and grinding of the guide rail soft belt after the guide rail is pasted with plastic are all done manually, which is time-consuming and laborious. , the quality of the scraped guide rail is closely related to the scraping level, which is not conducive to reducing the cost of high-precision sliding guide rails and ensuring the consistency of accuracy
