Machining process of linear guide

Abstract

The invention discloses a machining process of a linear guide. The process comprises the following steps of firstly, selecting a corresponding number of steel raw materials according to the material demand of a product, and then extruding the selected steel raw materials into a profile; cutting the profile into a plurality of sections of guide rails according to the requirements of a drawing, and then machining two sides of the guide rails through a multi-shaft different cutter to form chutes; then putting the guide rails obtained in the above-mentioned step into a heating furnace to be heated to 800-1000 DEG C, conducting heat preservation for 1-3 h, then cooling the guide rails to 200-220 DEG C, conducting heat preservation for 1-2 h, and finally cooling the guide rails to the room temperature; and then grinding and scraping the guide rails obtained in the above-mentioned step firstly to obtain the guide rails conforming to machining parameters, and then conducting galvanization treatment. By adopting the machining process designed by the invention, the linear guide can have good use strength and mechanical performance, the machining process is simple and efficient, meanwhile, the machined linear guide is high in precision, the quality of the guide rail is guaranteed, the service life is prolonged, and the requirements of customers can be met.

[0002] Linear guides are used to support and guide moving parts, and perform reciprocating linear motion in a given direction. Generally, they can be divided into roller linear guides, cylindrical linear guides, and ball linear guides. Linear guides are used for linear reciprocating motions. It has a higher rated load and can bear a certain torque at the same time, and can realize high-precision linear motion under high load conditions. The linear guideway has two basic components like the planar guideway; one is a fixed component as a guide, and the other is a It is a moving element. There is no intermediate medium between the moving element and the fixed element of the linear guide rail, but rolling steel balls are used, which can also be understood as a rolling guide. The steel balls roll endlessly between the slider and the guide rail. Make the load platform move along the guide rail easily and with high precision, and reduce the friction coefficient to one-fiftieth of the usual traditional sliding guide, which can easily achieve high positioning accuracy. The final unit design between the slider and the guide rail , so that the linear guide rail can bear loads in all directions such as up, down, left, and right at the same time. The return system and simplified structural design allow the linear guide rail to move more smoothly and with low noise. Carry out full milling to obtain the rough blank, punch holes, and then conduct overall heat treatment, and then carry out flat grinding and cutting on the rough blank by a grinding machine, so as to obtain the guide rail, but the work efficiency of flat grinding and cutting during the processing process is low, and at the same time, through conventional The guide rail obtained by this method has poor mechanical properties, low strength, and low precision, which cannot meet the needs of modern production.
