Abstract
The invention discloses a resistor butt welding beading automatic lathing device, which comprises a feeding station, a welding beading removing station I, a welding beading removing station II and a blanking station. The resistor butt welding beading automatic lathing device achieves automatic operation and streamlined operation, and improves the production efficiency. The feeding amount of a cutter is indicated by a precise cutter graduated disk, and can be adjusted. The whole process is strictly controlled by PLC, and processing precision can reach 0.0001 millimeter so as to fill the blank of domestic related technology. In order to guarantee the precision and cleanliness of a lathed piece and avoid polluting a lathing piece by oil, the prior pure mechanical or hydraulic design is not adopted during designing a control system and a movement system, but the design concept of combining PLC control and a pneumatic system is adopted. At the same time, a shield and a scrap removing device are specially designed so as to avoid radioactive cutting splashing pollution in the process of production. The resistor butt welding beading automatic lathing device skillfully designs a cutter lifting device, thereby avoiding remaining a cutter retracting mark on the wall of a workpiece during retracting the cutter after finishing cutting so as to ensure that the wall surface of the workpiece is smooth.
