Linear bearing assembly device

Abstract

The invention provides a linear bearing assembly device which comprises an outer shell, an inner shell, a handle, a vacuum sucker and a vacuum pump, wherein the outer shell is arranged outside the inner shell and can move along the surface of the inner shell; the inner shell is of a hollow structure; the front end of the inner shell is connected with the vacuum pump through the vacuum sucker; an elastic head positioning piece is arranged at the tail end of the inner shell; a plurality of through vacuum suction holes are distributed in the side wall of the tail end of the inner shell; the handle is arranged on the inner shell and is positioned between the outer shell and the vacuum sucker. According to the linear bearing assembly device, the difficulty in assembly of balls and a retainer of a linear bearing is smartly solved, when the linear bearing is assembled, only the retainer needs to be sleeved, the handle is pressed to suck the balls, then the balls are sleeved by the outer ring, and the whole assembly process of the linear bearing can be finished, so that the production efficiency is improved, the problems that the steel balls are missed, the positions of the steel balls are mistaken and the like are solved, and the quality of the bearing is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a linear bearing assembly device. Background technique [0002] Linear bearings are more and more widely used in precision equipment such as electronic equipment, food machinery, packaging machinery, medical machinery, printing machinery, textile machinery, machinery, instruments, robots, tool machinery, CNC machine tools, automobiles and digital three-dimensional coordinate measuring equipment Or in the special machinery industry. [0003] A linear bearing is a linear motion system produced at low cost for infinite travel in conjunction with a cylindrical shaft. Since the bearing ball is in point contact with the shaft, the operating load is small. Steel balls rotate with minimal frictional resistance, resulting in smooth motion with high precision. The retainer is installed inside the outer cylinder, and is fixed by buckles at both ends, so that the steel ball ...

AI Technical Summary

Problems solved by technology

[0005] The existing linear bearings are assembled manually with simple auxiliary tools. During the assembly process of the linear bearings, due to the small diameter of the balls (less than 2mm), it is difficult to control the assembly of the balls during manual installation, resulting in dropouts during the assembly process. Problems such as steel balls, steel balls installed in the wrong position, slow assembly speed, etc., thereby reducing production efficiency and cannot guarantee product quality

And long-term installation will cause damage to the eyesight of the installer, thereby increasing the labor loss cost of the factory
