Biaxial adjusting device for welding

Abstract

A biaxial adjusting device for welding comprises a Z-direction adjusting mechanism, an X-direction walking mechanism, a Y-direction walking gantry crossbeam, an R-axis rotating mechanism, an XY bidirectional adjusting mechanism, a guide rail, a sliding block, a weld joint identification controller, a welding gun, a Z-axis sliding connecting plate, Y-direction walking gantry stand columns and an R-axis connecting plate. The Z-direction adjusting mechanism is in threaded connection with the X-direction walking mechanism, the Z-axis sliding connecting plate is arranged at the lower part of the Z-direction adjusting mechanism, the R-axis rotating mechanism is in threaded connection with the Z-axis sliding connecting plate, the R-axis connecting plate is arranged at the bottom end of the R-axisrotating mechanism through a connecting bar, and the XY bidirectional adjusting mechanism is in threaded connection with the R-axis connecting plate below the R-axis rotating mechanism. The weld joint identification controller is fixedly arranged at the front end of the welding gun, and the welding gun and the weld joint identification controller are arranged below the R-axis rotating mechanism together and located at the front end of the XY bidirectional adjusting mechanism. The biaxial adjusting device for welding realizes simultaneous multi-direction position correction of weld joints andis higher in welding accuracy, high in tracking accuracy, free of dead angles and good in tracking timeliness.

Description

technical field [0001] The invention belongs to the technical field of car body welding, and in particular relates to a biaxial adjustment device for welding of a special-purpose vehicle. Background technique [0002] Automobile welding technology is an important link in the automobile manufacturing process. The production of automobile engines, compartments, transmissions, axles, and frames cannot be separated from welding technology. Some parts of the car need special strength materials as support during production. For example, large gears and wheel rims need to be made of high-strength alloy steel. The strength of the material can ensure the service life of the car. However, high-strength The price of steel is relatively high, which will increase the cost in the process of producing automobiles. The application of welding technology replaces the use of alloy steel, and improves the durability of gears, reducing the production cost of automobiles. Especially in automobil...

Problems solved by technology

However, this type of robot also has shortcomings: in actual use, sometimes there are shortcomings such as inflexibility in specific adjustments, less direction and angle changes, and large errors in adjustment accuracy.

[0009] Fourth, the existing automatic welding adjustments on the market are cumbersome, not flexible enough, and have few changes in direction and angle; in addition, the direction, angle and height of the adjustment cannot be well controlled accurately, which will cause great damage to the welding torch and damage the welding seam. Disadvantages such as large errors;

[0010] Fifth, the tracking accuracy is not enough, the tracking timeliness is poor, and the degree of automation, intelligence, and high efficiency needs to be improved
