Quick pulling device for knife row drill bits of schmoll drilling machine

Abstract

The invention discloses a quick pulling device for knife row drill bits of a schmoll drilling machine. The quick pulling device comprises a pulling device body, a drill bit clamping groove, a rubber ring containing cavity, a baffle and a rubber ring isolation cavity. The drill bit clamping groove is formed in one side face of the pulling device body. The rubber ring containing cavity is adjacent to and communicated with the drill bit clamping groove. The baffle is arranged in the middle of the pulling device body. Drill bit protection layers extend out of the upper surface and the lower surface of the pulling device in the thickness direction of the pulling device body. The rubber ring isolation cavity is formed between the rubber ring containing cavity and the baffle and communicated with the rubber ring containing cavity. By means of the quick pulling device, a plurality of drill bits can be pulled at a time, the pulling efficiency of the drill bits is improved, and the product cost is lowered; the situation that when operation staff manually pulls the drill bits one by one, the drill bits are broken, the body of the personnel staff is damaged, and the service life of the drill bits is shortened is avoided; and the baffle plays a protection function, the drill bits are prevented from pricking fingers, and the safe work of the operation personnel is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of printed circuit boards, and relates to a drilling device, in particular to a quick extraction device for a schmoll drilling machine cutter row drill tip. Background technique [0002] A printed circuit board is an important electronic component, which is specifically a support for electronic components and a provider of electrical connections for electronic components. During the circuit board manufacturing process, it is usually necessary to drill holes on the circuit board to realize the upper and lower conduction of the circuit board lines and interlayer interconnection, and to play the role of installing parts or parts screws. The drilling process is generally carried out with the schmoll drilling machine and the matching drill nozzles, and the drill nozzles are used to position and fix the drill nozzles. After the drilling is completed, the drill nozzles on the cutter row need to be pulled out in tim...

Problems solved by technology

[0003] For this reason, the technical problem to be solved by the present invention is that the process of extracting the drill bit in the existing drilling equipment adopts a manual operation mode, which easily leads to the breakage of the drill bit, increases the cost of raw materials, and is easy to scratch the operator, and at the same time, the manual extraction work efficiency is low , The labor intensity of the operator is high, and the production cost is high, so a schmoll drilling machine cutter row drill tip quick extraction device with high extraction efficiency and protective measures is proposed
