Integrated machine for resharpening and replacing electrode cap

An integrated machine for resharpening and replacing an electrode cap comprises a machine frame (1), a drive motor (6) mounted on the machine frame (1), and a balance-floating unit (2). An output end of the driver motor (6) penetrates through the balance-floating unit (2) and then is connected with a workbench (7). A cap detaching unit (3) and a cap resharpening unit (4) are arranged on two sides of the workbench (7), and electrode cap storing units (5) are mounted on both outermost ends of the two sides of the workbench (7). The resharpening and replacement of an electrode cap are completed on one device, and the drive motor is used as a power source, so that a control system is simple, an output speed is stable, and problems that an automobile production line is stopped to manually replace the electrode cap and a large area is occupied by two machines that separately perform cap resharpening and replacement, thereby improving the production capacity of an automobile welding production line. The machine is applicable to a highly-automated automobile welding production line.
