Problems solved by technology

If the slider body of this method is of a large size, the overall mold needs to use a large mold; and the injection molding accuracy is relatively high, and the difficulty is relatively high, so the dimensional tolerance of the slider body before injection is required. High, so that it can fit closely with the injection mold; in addition, the supporting member is a structure with thin walls and long sides, which is not easy to form

Abstract

The roller type linear slide rail consists of mainly slide rail, block body, roller module, circulating module, end cap and other parts combined together. The present invention features the circulating module comprising two semi-circulating modules combined in special angle, the semi-circulating module comprising two U-shaped semi-circulating sheets combined together, the semi-circulating sheet comprising integrally formed turning block, support strip and reflux semi pipe, and two rows of roller modules in X-shaped cross turning and rolling in the turning part. Therefore, the present invention may be assembled without need of more fittings and in short time, and has easy forming process and low cost.

Description

technical field [0001] The present invention relates to a roller type linear slide rail. The linear slide rail generally provides precise control of linear transmission and is widely used in mechanical arms, industrial machinery, mechanical industry, automation equipment, measuring machines and electronic equipment. However, roller linear slides are used in large-scale machines or places with heavy load-bearing requirements to improve the rigidity and accuracy of the machine. Background technique [0002] The linear slide rail mainly includes a rail bar with a rolling surface of a rotating body, a sliding block assembly fitted on the rail bar and sliding on the rail bar, and a plurality of rotating bodies rolling between the rail bar and the sliding block assembly. Among them, if the rotating body of the linear slide is a cylindrical structure, it is called a roller linear slide. [0003] The rotating body circulation system of the roller linear slide rail generally include...
