Description

Technical Field

[0001] This utility model relates to the field of door panel welding processing, and in particular to a door panel reinforcing rib welding machine. Background Technology

[0002] To increase structural strength, existing door panels often have reinforcing ribs welded onto them to enhance load-bearing capacity. Current designs typically employ manual welding, which is relatively inefficient and labor-intensive. To reduce labor costs, equipment similar to baffle processing is often used. Referring to patent CN202311551951.3, this method involves blocking the door panel, placing reinforcing ribs, and then spot welding the door panel and ribs together.

[0003] However, the existing door panel connection method using spot welding is not stable enough. Therefore, the door panel and the reinforcing rib are first connected by spot welding, and then completely connected by pull welding. However, since the door panel is uneven after connecting the reinforcing rib, how can we ensure the accuracy and effect of the welding? Utility Model Content

[0004] The main purpose of this utility model is to provide a door panel reinforcing rib welding machine that can position the door panel by means of reinforcing ribs and accurately weld the door panel and reinforcing ribs by means of a welding positioning mechanism, thereby improving the final welding effect.

[0005] This utility model proposes a door panel reinforcing rib welding machine, including a frame, an X-axis motion mechanism, a Y-axis motion mechanism, a welding positioning mechanism, and a door panel positioning device. The X-axis motion mechanism is mounted on the frame and fixedly connected to the frame. The Y-axis motion mechanism is mounted on the X-axis motion mechanism and can move in the X-axis direction through the X-axis motion mechanism. The welding positioning mechanism is mounted on the Y-axis motion mechanism and can move in the Y-axis direction through the Y-axis motion mechanism.

[0009] The welding positioning device is located at the bottom of the welding device and can be clamped on the outside of the reinforcing rib. At this time, the laser welding device is exactly above the reinforcing rib, so that the door panel and the reinforcing rib can be welded by the laser welding device.

[0010] Preferably, the door panel positioning device includes a limiter and a door panel positioning device body. The limiter limits the door panel, and the door panel positioning device body includes a positioning device body cylinder and a positioning block. The positioning device body cylinder drives the positioning block to move and press the door panel, thereby positioning and fixing the door panel.

[0011] Preferably, the front guide positioning device further includes a first skateboard seat, a first skateboard, a guide bracket, a guide rod, and a guide wheel mounting plate. The rear side of the first skateboard seat is connected to the connecting fixing plate. The first skateboard is slidably connected to the first skateboard seat.

[0015] The positioning and clamping cylinder is located on the bottom of the guide wheel mounting plate, and the side guide wheel is located on the two clamping arms of the positioning and clamping cylinder. The positioning and clamping cylinder can drive the side guide wheel to move, thereby clamping the reinforcing rib.

[0016] The positioning and pressing cylinder is mounted on the guide wheel mounting plate in front of the positioning and clamping cylinder. The upper guide wheel is mounted on the bottom of the positioning and pressing cylinder. The positioning and pressing cylinder drives the upper guide wheel to move, thereby pressing on the top of the reinforcing rib.
