Integrated retainer for linear module

Abstract

The invention relates to an integrated retainer for a linear module. The integrated retainer comprises a pair of inner circulation components which are oppositely arranged, an upper retainer component, a middle retainer component and a lower retainer component, wherein the upper retainer component, the middle retainer component and the lower retainer component are fixedly connected between the pair of inner circulation components; the pair of inner circulation components, the upper retainer component, the middle retainer component and the lower retainer component are integrally formed and connected; the upper retainer component and the middle retainer component are arranged in parallel at an interval and form an upper rolling groove body of a ball; the middle retainer component and the lower retainer component are arranged in parallel at an interval and form a lower rolling groove body of the ball; and a clamping portion clamped at a rolling path port of a sliding block is arranged on the inner side surface of each inner circulation component. The inner circulation components, the upper retainer component, the lower retainer component and the middle retainer component are of an integrated structure, so that the sliding block is smooth in operation and long in service life, mutual splicing and assembling of backflow assemblies are avoided, assembling is carried out in a clamping mode, the assembling time of the sliding block is greatly shortened, and the assembling efficiency of the sliding block is improved.

Description

technical field [0001] The invention relates to the technical field of linear modules, in particular to an integrated cage used on linear modules. Background technique [0002] At present, linear slide rails are used in linear reciprocating motion applications, and can bear a certain torque, and can achieve high-precision linear motion under high load conditions. Linear slide rails are mainly used in mechanical structures with high precision requirements. There is no intermediate medium between the moving elements and fixed elements of the linear slide rails, but rolling steel balls are used. The linear slideway is mainly composed of the following parts: bearing system, circulation system, dust-proof system and lubrication system. The circulation system is composed of various return components, including inner circulation, upper cage, lower cage and middle cage. , the rolling assembly can be reciprocated and rolled between the slider and the guide rail through the reflow as...

Problems solved by technology

At this stage, the circulation system of most linear sliders is composed of multiple components assembled with each other, which makes the integrity of the circulation system and the bearing system poor. There are certain errors in the processing and assembly of each component, and there is a certain gap between the components. , so that the linear slider will vibrate when it is working, and the sliding is not smooth, and the service life is not long. In the prior art, when the slider is assembled, it is necessary to assemble the various parts of the reflow assembly in sequence, so that the assembly of the slider The time is greatly increased, making the assembly of the slider inefficient
