Overturning operation table for automobile sheet metal welding six-shaft mechanical hand

Abstract

The invention discloses an overturning operation table for an automobile sheet metal welding six-shaft mechanical hand. The overturning operation table comprises a six-shaft welding mechanical hand body and a welding bottom table, wherein the six-shaft welding mechanical hand body is on one side of the welding bottom table; a left-right moving mechanism is arranged on the welding bottom table; a front-back moving mechanism is arranged on the left-right moving mechanism; an up-down compensation feeding mechanism is arranged on the front-back moving mechanism; an overturning mechanism is arranged on the up-down compensation feeding mechanism; and a clamping mechanism is arranged on the overturning mechanism. The overturning operation table has the beneficial effects that the technical scheme is that a plurality of compensation mechanisms are added at the outer part on the basis of six degrees of freedoms of a six-shaft robot, a plurality of degrees of freedom are added equivalently, the entire device has more than six degrees of freedom, a user can weld various complex parts according to different utilization requirements, limitation of the degree of freedom of the robot is effectively filled, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of welding equipment, in particular to a turning console for a six-axis manipulator used in automobile sheet metal welding. Background technique [0002] The car body is usually welded by about 300-500 stamping parts, with as many as 1700-2500 clamping points and 1500-2000 welding points. The structure of the automobile body is complex, the rigidity is poor, and it is easy to deform, and the manufacturing deviation is difficult to control; the accuracy is required to be ±1mm, and the important shape and surface accuracy needs to reach ±0.8mm. The trial production of the automobile body is a multi-level structure. Several parts are welded into the component assembly, and the sub-assembly becomes the part in the next layer of assembly; the welding fixture ensures the relative position of the welding parts and the dimensional accuracy of the weldment, reducing the Parts are deformed during the welding process, and the d...

Problems solved by technology

[0003] In the prior art, when the welding robot welds the automobile sheet metal parts, the shapes are different due to the different purposes of different sheet metal parts. At present, most welding robots are fixedly installed and cannot move left and right, so It is difficult to complete the overall welding, which may lead to the need for manual welding in the future, and manual welding is likely to make mistakes, and also reduces production efficiency. If manual flipping of sheet metal parts is used, it may pose a certain threat to the person, so it is necessary to A flipping device that works with a six-axis welding manipulator
