According to the technical solution provided by the present invention, the automatic assembly mechanism in the double C-shaped steel automatic welding machine includes a fixed wheel mechanism, a pushing and positioning mechanism, an upper pressure roller mechanism, a first cylinder, a guide rod and a second cylinder.

The fixed wheel mechanism adopts that dust-proof bearings are installed at both ends of the positioning wheel shaft, and the positioning wheels are installed outside the dust-proof bearings and installed in the fixed seat, and the upper end of the fixed seat is covered with a cover plate.

The pushing and positioning mechanism uses a moving seat to move on a linear guide rail. Dust-proof bearings are installed at both ends of the shaft and installed in the positioning wheel. This part is installed in the moving seat. The upper part of the moving seat is covered with a cover plate, and the moving seat passes through the connecting seat. Connect with the pin shaft and the second cylinder, so that the second cylinder can push and stretch the entire pushing and positioning mechanism;

The lower part of the upper pressure roller mechanism adopts dust-proof bearings installed at both ends of the shaft, and is installed in the bearing seat as a whole. The bearing seat is welded on the fixed seat. The main body of the fixed seat is connected, and the conveying roller is installed outside the shaft, and the conveying roller presses the workpiece. A guide rod is installed in the guide sleeve.

Compared with the prior art, the present invention has the following advantages:

The structure of the invention is simple, compact and reasonable; it mainly adopts the fixed wheel mechanism to position the two C-shaped steel sides to prevent the side dislocation of the two C-shaped steels, and pushes the workpiece to the fixed wheel mechanism by the push-tight positioning mechanism, effectively ensuring that the workpiece is in the correct position. At the welding position, the workpiece is pressed against the driving roller by the upper pressure roller mechanism, which increases the friction between the workpiece and the driving roller, so that there is no sliding friction between the workpiece and the driving roller, so that the automatic assembly of double C-shaped steel can be realized. stand. The automatic assembly of double C-shaped steel is completed by using the automatic control of electrical appliances. The clamping workpiece is stable, firm and reliable, and the assembly cost is low and the efficiency is high.
