Precise six-degree-of-freedom assembly robot

Abstract

The invention discloses a precise six-degree-of-freedom assembly robot, and relates to the technical field of six-degree-of-freedom assembly robots. The precise six-degree-of-freedom assembly robot comprises a six-axis robot body and an assembly table, the six-axis robot body is located at the front side of the assembly table, and two symmetrically-arranged shelving plates are slidably connected to the top of the assembly table; and the top of the assembly table is connected with a driving mechanism used for driving the two shelving plates to move towards the middle of the assembly table simultaneously. According to the precise six-degree-of-freedom assembly robot, when the six-axis robot body is used for fastening a bolt every time, the bolt is guided through a through groove formed by a first connecting plate and a second connecting plate, so that the bolt can be smoothly aligned to a threaded hole of a workpiece every time, the bolt does not need to be clamped by the six-axis robot body for thread fastening, the situation that the bolt cannot be aligned with the threaded hole of the workpiece and the workpiece is damaged due to track changes caused by deviation or fixing looseness in operation of the six-axis robot body is avoided, and the working safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of six-degree-of-freedom assembly robots, in particular to a precision six-degree-of-freedom assembly robot. Background technique [0002] Over the past few years, with the continuous development of industrial technology, a large number of welding, casting, painting, handling, assembly and other occasions in the industrial field have begun to use robots to replace manual operations. In addition, robots have also begun to be used in the military, ocean exploration, aerospace, medical agriculture, forestry, and even service and entertainment industries. Robots have become one of the important and indispensable automation equipment that replaces manpower. [0003] Among the invention patents disclosed in the prior art on six-degree-of-freedom assembly robots, the Chinese patent application number CN201610997136.3 discloses a precision assembly robot, including a base, a turntable, a large arm, a small arm, Wri...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a precision six-degree-of-freedom assembly robot to solve the above-mentioned background technology. In the prior art, in the process of using a six-degree-of-freedom robot to screw a workpiece, the robot is often used to remove the screw first. Then fasten the workpiece that needs to be fastened. The screw is at the end of the robot. When the robot fastens the workpiece, the screw cannot be accurately aligned with the threaded hole of the workpiece due to the damage of the robot's repeated use or the deviation of the running track. It will directly damage the workpiece, and the robot may malfunction under the reverse action, which is not conducive to the precise installation of the robot
