Automobile sheet metal automatic welding robot

Abstract

The invention relates to an automatic welding robot for a car metal plate. The robot comprises a fixed frame, a thread connecting pipe is arranged at the upper end of the fixed frame, a telescopic aircylinder is arranged at the lower end of the fixed frame, the lower end of the telescopic air cylinder is mounted an execution work pipe through a flange, and the inner side wall of the lower end ofthe execution work pipe is provided with an inner pipe located on the same axis with the execution work pipe. In the process that an existing car metal plate car door and an inner plate are welded andfixed, the problems that a clamp needs to be manually used for fixing the inner plate to the car door, the position where the inner plate is fixed to the car door needs to be manually controlled andadjusted according to the naked eye observation, the precision is poor, the car door use effect is affected, the clamp is manually used for fixing the inner plate, the inner plate surface flatness cannot be ensured, the clamping strength cannot be controlled, the inner plate is easily sunken into a cavity in the car door, and the sunken inner plate needs to be secondarily repaired are solved.

Description

technical field [0001] The invention relates to the technical field of automobile processing equipment, in particular to an automatic welding robot for automobile sheet metal. Background technique [0002] Automobile sheet metal welding is one of the main processes in the production process of automobile assembly. In automobile production, the inner panel of the car door needs to be welded. There is a cavity on the car door for installing the control device of the window on the door and welding the inner panel of the car. It is mainly to protect the components on the car door. The quality of the inner panel welded on the door directly affects the use effect of the car door. In addition to the technical requirements for welding, the welding operation is also very important for the fixing between the door and the inner panel. . [0003] However, the following problems exist in the welding and fixing process of the existing automobile sheet metal door and the inner panel, a. I...

AI Technical Summary

Problems solved by technology

[0003] However, the following problems exist in the welding and fixing process of the existing automobile sheet metal door and the inner panel, a. It is necessary to manually use the fixture to fix the inner panel on the door, and it is necessary to manually adjust the position of the inner panel fixed on the door according to the observation and control of the naked eye , the accuracy is poor, which affects the use effect of the car door. b Manual use of clamps to fix the inner panel cannot ensure the smoothness of the surface of the inner panel, and the clamping force cannot be controlled. It is easy to cause the inner panel to fall into the cavity opened on the door. The sunken inner panel undergoes secondary repair processing

[0004] Regarding some problems existing in the automobile welding process, related industries have made research and proposed specific technical solutions, such as the Chinese utility model patent No. 2017200623054, a welding platform for automobile panels, which can be used for welding Support and fix different types of automobile sheet metal parts, but the problems mentioned above about the welding process of automobile doors and inner panels are not involved
