A linear guide rail at the end of a robot

Abstract

The invention relates to a robot tail end linear guide rail. The robot tail end linear guide rail comprises a sliding block (2) connected with a robot tail end (1) and a track (4) connected with a robot rack (3). The track (4) is a rectangular column. The sliding block (2) is arranged outside the rectangular column in sliding and sleeving modes. Each side face of the sliding block (2) is provided with two bearing holes (5) in the width direction. The sliding block (2) is fixedly provided with a mounting base (6). A connecting frame (7) is arranged on the mounting base (6) in a swinging mode. Bearings (8) are arranged at the two ends of the connecting frame (7) and are located in the corresponding bearing holes (5). The bearings (8) and the track (4) are in rolling fit in the sliding direction of the sliding block (2). The robot tail end linear guide rail is simple in structure, low in processing accuracy requirement, easy to assemble, and capable of achieving automatic balance and effectively prolonging the service life.

Description

technical field [0001] The invention relates to parts of a robot, in particular to a linear guide rail at the end of a robot. Background technique [0002] With the development and maturity of robot technology, there are more and more places where the end of the robot (manipulator and other actuators) needs to use linear motion, such as linear handling of materials, linear extension of robots and other common applications. The linear movement of the end of the robot is usually realized by a linear guide. [0003] The existing linear guide rail at the end of the robot includes a slider connected to the end, the slider cooperates with the track through several rows of steel balls, and the track is installed on the frame of the robot. The linear sliding between the slider and the track is realized by rolling several rows of steel balls in the chute of the slider and the track, and then the linear motion of the end of the robot is realized. The rows of steel balls in the chute...

AI Technical Summary

Problems solved by technology

The rows of steel balls in the chute of the slider and the track can neither be too tight nor too loose, but must be precisely matched at the micron level; the processing accuracy is high, the assembly is difficult, and it is easy to damage

[0004] In order to prevent the steel balls from being misaligned and squeezed each other in the chute, a cage is usually added to the steel balls, and in order to prevent the steel balls from falling off, a baffle is also provided. One-position assembly is extremely inconvenient; it also makes it easy to damage and difficult to maintain, and also increases the cost of robot maintenance and repair
