Abstract

Welding machine for the specified the workpiece and must be the shape of the welding joint and special design of welding equipment.It can be used for welding power source and with other units in the automatic welding system.The machine mainly by the rotary worktable, displacements of institutions and controller.Rotary worktable speed adjustable, with independent control circuit.

The subject of design requirement for Stretching arm-the welding dislodgement machine are one of the most widely applied a deflection welding machine.Load for no more than a ton of general,and request for 0.5 tons.Stretching arm-the welding dislodgement machine`s main parts are the displacement worktable rotary organization, flip institutions and base.The design is mainly design of workbench rotary institutions and arms outstretched rotating mechanism and a p art and parts of a parameter selection,demand has good stability and impact resistance.The smooth realization of rotary and arms outstretched to drive the cone Angle of 45 ° rotation,control circuit of the main frequency converter is to control.

Stretching arm- welding dislodgement machine is advantageous to the realization the best position welding process, improves the working efficiency, reduces the fatigue strength and achieves the good welded joint shape.

Keywords:streching arm-welding;dislogement machine;over organization; reducer
