High-accuracy car welding robot

Abstract

The invention discloses a high-accuracy car welding robot. The high-accuracy car welding robot structurally comprises a chassis, a base, a wiring box, a front arm, an upper arm, a small arm, a rotaryflange disc, a welding gun, a connecting plate and a rotary shaft, wherein the upper end of the chassis is laminated with the lower end of the base; the wiring box is arranged at the upper end of thebase; and the upper arm is embedded and connected in the front arm which is connected with the rotary shaft. The high-accuracy car welding robot disclosed by the invention has the advantages that theleft side of the welding gun is welded with the right side of the connecting plate, and by mechanical movement of the front arm, the upper arm and the small arm, the welding robot can move in all directions; by rotation of the rotary flange disc, the welding gun can carry out all-directional welding; the size of the air pressure in a mixed gas pipe is controlled by the tightening degree of an oxygen handwheel, and then the speed of shrinkage of an injection pipe is accelerated, so that the welding speed of a welding nozzle is accelerated; and the welding speed of the welding gun can be controlled when a worker uses a tin-welding robot, so that the welding accuracy of the robot is improved.

Description

technical field [0001] The invention relates to a high-precision automobile welding robot, which belongs to the technical field of welding robots. Background technique [0002] Traditional tandem robots have the advantages of simple structure, low cost, and large working space. However, with the development and progress of society and the improvement of people's living standards, the requirements for cars are getting higher and higher. The shortcomings of traditional tandem robots are gradually emerging. Therefore, a new type of automobile welding device is urgently needed. Compared with the traditional serial robot, the emerging parallel robot has no cumulative error, high precision, compact structure, large carrying capacity, Due to the characteristics of high rigidity and small inertia of the end welding actuator, the driving device can be placed on or close to the fixed platform, so that the moving part is light in weight, high in speed and good in dynamic response.
