Description

Technical Field

[0001] The utility model belongs to the technical field of drill bit production and relates to a bidirectional clamping jaw for PCB drill bit production. Background Art

[0002] The drill bit is one of the indispensable tools in the production of PCB boards. By using the high-speed rotation of the drill bit to open 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. The drill bit is generally processed by a cemented carbide rod to obtain a PCB drill bit.

[0003] When producing existing PCB drill bits, drill rods need to be processed. Electric clamps are used for loading during the processing of drill rods. Existing loading devices all load materials through electric clamps. When loading, the electric clamps need to perform four steps: picking up materials, rotating, releasing materials, and reverse rotation, so as to return to the initial position for loading again. However, the repeated rotation steps result in a long interval time during loading and low loading efficiency. Therefore, we propose a bidirectional clamp for PCB drill bit production.
