Description

Technical Field

[0001] The utility model belongs to the technical field of milling cutter production and relates to a butt joint device for PCB milling cutter welding. Background Art

[0002] Milling cutters are one of the indispensable tools in PCB production. By utilizing the high-speed rotation of the milling cutter to drill holes in the PCB board, the production speed of the PCB board can be increased and the processing difficulty of the PCB board can be reduced. Generally, carbide rods and milling cutter rods are welded to obtain a complete PCB drill bit.

[0003] During the production of existing PCB milling cutters, it is necessary to weld a carbide shank and a drill bit bar. Before welding, the carbide bar and the milling cutter bar need to be butted together so that the end faces of the carbide shank and the milling cutter bar fit together. Existing welding equipment requires manual single-time loading and then extrusion and butting through the equipment. After welding is completed, manual unloading is required, resulting in poor welding efficiency. Therefore, this paper proposes a butt-jointing device for PCB milling cutter welding.
