Gantry automatic welding machine

Automatic welding machine can not only reduce the labor intensity of workers and shorten the welding time, but also greatly increase the output of products on the premise of improving the quality of products. It can bring considerable economic benefits to the company and is sought after by enterprises. However, high-cost automatic welding machine is far away from small and micro enterprises. Therefore, it will have a good development prospect and social benefits to develop a reasonable cost automatic welding machine suitable for small and micro enterprises.

The structure of gantry automatic welding machine is mainly composed of bracket, column, cross arm, lifting mechanism and control box. The bracket is aluminum profile connector and rectangular guide rail structure. The servo motor is directly connected with the lead screw to drive the column to realize linear movement; the column is square aluminum profile, the top of the column is cross arm, and the servo motor is directly connected with the ball screw transmission mechanism, the screw is connected with the sliding plate mechanism of the cross arm, the outer side of the sliding plate mechanism is connected with the lifting mechanism, and the other side of the cross arm is fixed on the LHA gantry auto-welding machine column with additional counterweight protection Syndrome balance.

The lifting mechanism is supported by parallel aluminum profile, and the external connecting plate (welding gun) is driven by servo motor direct connecting screw to realize linear movement, and its movement speed can be adjusted arbitrarily according to the needs. The control box is composed of word control system, servo control system and strong current control system. The control box has a man-machine dialogue device, which can be programmed according to the welding shape to realize automatic processing. The movement of the column, cross arm and lifting mechanism of the servo control system can realize the moving welding of the plane track of the electric welding gun.

The automatic welding machine adopts LHA gantry column, which makes up for the insufficient arm strength and limited processing range of cantilever welding machine. It can realize the automatic welding of plane straight line and curve at the same time, avoiding the error caused by repeated clamping, and has high reliability. Combined with the brand numerical control system independently developed by the market, the automatic welding machine is set up systematically, which greatly reduces the success of the automatic welding machine The welding accuracy is improved.
