The invention provides a double-head friction welding machine, which comprises two power heads, a control device, a body and two absolute grating scales, wherein each absolute grating scale comprises a grating scale body and a reading head; the grating scale body is connected with the power heads and can move along the power heads; and the reading head is fixedly arranged on the body and can be matched with the grating scale body to read the numerical reading of the grating scale body and transmit the reading result to the control device so as to switch operating states of the double-head friction welding machine by matching with the control device. The traditional travel switch is replaced by the absolute grating scales, the operating states of the double-head friction welding machine are switched, when parts to be welded with different lengths are welded, only technical parameters are required to be input into the control device, and the mounting position of the travel switch on the body is not required to be replaced, so that the automaticity and working efficiency of the double-head friction welding machine are obviously improved, and the workload of a controller is lightened. The invention also provides a control method for the double-head friction welding machine.
Description
technical field [0001] The invention relates to the technical field of mechanical processing, and more specifically relates to a double-head friction welding machine and a control method thereof. Background technique [0002] Friction welding machine is a device that uses the principle of friction heating to weld the end faces of two metal parts to be welded together. It uses the rotating fixture driven by the motor to hold one part to be welded to rotate, and the main cylinder pushes the other part to be welded held by the moving fixture. The workpiece is close to the rotating workpiece to be welded. After the two workpieces to be welded are in contact, the two workpieces to be welded are heated and pressurized by mutual friction to cause plastic deformation, surface activation and recrystallization of the two workpieces to be welded on the friction end faces. And form the welding joint, to realize the welding of two parts to be welded. [0003] The double-head friction we...
