Technical Field
[0001] The utility model relates to the technical field of linear guide rails, in particular to a high-load linear guide rail for a grinding machine tool. Background Art
[0002] Linear guides are used for high-precision or high-speed linear reciprocating motion, and can bear a certain torque, and can achieve high-precision linear motion under high load conditions;
[0003] The function of linear guides is to support and guide moving parts to perform reciprocating linear motion in a given direction. Depending on the nature of friction, linear guides can be divided into sliding friction guides, rolling friction guides, elastic friction guides, fluid friction guides, etc. Linear bearings are mainly used in automated machinery, such as machine tools imported from Germany, bending machines, laser welding machines, etc.
[0004] Linear guides have been used in existing grinding machine tools. However, in the existing linear guide structure of grinding machine tools, most of them are assembled with high rails and low slides to meet the load requirements. In actual use, there are technical problems that the guide rails are easily worn or the accuracy is easily reduced. At the same time, the load borne by the guide rails is light, which reduces the overall use effect. For this reason, the utility model proposes a high-load linear guide for grinding machine tools. Utility Model Content
[0005] The purpose of the utility model is to provide a high-load linear guide rail for a grinding machine tool to solve the problems raised in the above background technology.

[0007] Preferably, external connection columns are provided on the front and rear end outer walls of the guide rail screw, and the guide rail screw and the external connection columns are designed as an integrally formed structure.
[0008] Preferably, the outer shape of one end surface of the guide rail slider adopts a flat elliptical structure design.
[0009] Compared with the prior art, the beneficial effects of the present invention are:
[0010] The guide rail slider and guide rail screw of the utility model have the installation effect of high slider and low rail during installation, that is, the combined height between the rail and the slider remains unchanged, and the installation effect of low rail and high slider is achieved by reducing the rail height and increasing the thickness of the slider. In actual use, the thickened slider can effectively increase the overall load weight of the linear guide rail, reduce the load wear of the rail, effectively improve the load capacity and rigidity of the guide rail, and improve the use effect;
[0011] At the same time, a four-row single arc tooth contact setting is adopted between the guide screw and the guide slider. This structural design has a good load contact effect and can absorb the assembly error of the installation surface. The overall guide rail has high precision, high speed, high load, high rigidity and good performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The guide rail slider 2 and the guide rail screw 1 of the present invention have the installation effect of high slider and low rail during installation, that is, the combined height between the rail and the slider remains unchanged, and the installation effect of low rail and high slider is achieved by reducing the rail height and increasing the slider thickness.

The guide slider 2 is externally installed with a sliding load member, so that the movement of the guide slider 2 can drive the sliding load member to perform an overall linear displacement, thereby ensuring the normal transmission use of the linear guide.
[0027] The guide rail slider 2 and the guide rail screw 1 of the present invention have the installation effect of high slider and low rail during installation, that is, the combined height between the rail and the slider remains unchanged, and the installation effect of low rail and high slider is achieved by reducing the rail height and increasing the slider thickness.
