Description

• Equipment Description :
The production efficiency is greatly enhanced by the automatic transport between the two stations through the transmission cart. The equipment consists of multiple system: two of supporting positioning systems, stretching machine, gantry welding system, transmission cart, NC system, etc; can be applied to top frame with parameters of length between 6 to 12m, width 1.8 to 2. 5m, and height 150 to 400mm.

• Operation Process :

The top frame is sat on the positioning system. One end of the top skin is welded on the frame and the other end is clamped on the tension system used to stretch the skin. Then spot welding machine is used for positioning welding.

• Equipment Structure :

Automatic Spot Welding System :

The equipment adopts two sets of AC servo motors and reducer. The gantry is driven by gear and rack device to step on the guide rail to ensure synchronization and accurate positioning. Walking speed is less then 15m/min.

Equipped with two sets of welding system, double-sided spot welding is adopted, and welding of both sides of roof skin and frame is completed at the same time. Self-contained circulating cooling system, reliable cooling effect.

Open programming, parameter preset with memory function. The position (height and width) of welded joint can be adjusted. The roof frame positioning device can be adjusted according to the different types of vehicles, which is convenient and fast.
