021.30.1120-2_Double row variable diameter slewing bearing with external gear for Electric displacement machine

The displacement machine is mainly composed of a workbench, a rotary and a turning mechanism, a conductive device, a frame and an electric control box.

displacement machine is a special welding auxiliary equipment, suitable for rotary work of welding displace to get the ideal machining position and welding speed. It can be used with manipulator and welder to form an automatic welding center, and can also be used for the displacement of work piece during manual operation. Rotary table adopts frequency converter stepless speed regulation, high precision speed regulation. The remote control box can realize the remote operation of the workbench, and also can be connected with the control system of the manipulator and welding machine to realize linkage operation. The welding displacement is generally composed of rotary mechanism and turning mechanism of the worktable. Through the lifting, turning and turning of the worktable, the work piece fixed on the worktable can reach the required welding, assembly angle, and the worktable is converted to frequency conversion step less speed regulation, so that the welding speed can be meted.
