Automatic drill bit grinding equipment

Abstract

The invention provides automatic drill bit grinding equipment and belongs to the technical field of drill bit machining. The automatic drill bit grinding equipment solves the problems of how to achieve automatic production of micro-drill machining and improve the machining precision and the production efficiency. The automatic drill bit grinding equipment comprises a machine table, wherein a rotary multi-station machining module is positioned in the middle of the machine table; four working heads are rotationally arranged on the rotary multi-station machining module; a feeding and dischargingmodule, a grooving station module, a tip grinding station module and a back grinding station module are sequentially arranged on the machine table in the counter-clockwise direction around the rotarymulti-station machining module; a grooving station adjusting seat is correspondingly arranged on the inner side of the grooving station module; a tip grinding station adjusting seat is correspondinglyarranged on the inner side of the tip grinding station module; and a back grinding station adjusting seat is correspondingly arranged on the inner side of the back grinding station module. Accordingto the automatic drill bit grinding equipment, automatic production of a drill bit is completed through the procedures of feeding, grooving, tip grinding, back grinding and discharging, the proceduresare coherently connected, the production efficiency is greatly improved, the machining precision is high, the operation is stable, the adjustability is high, and the product quality is improved.

Description

technical field [0001] The invention belongs to the technical field of drill bit processing, in particular to an automatic drill bit grinding device. Background technique [0002] The drill bit is a commonly used tool for opening holes, and the drill bit is cut by bar grinding. PCB micro-drills are micro-drills used to open holes in PCB circuit boards. As electronic products become lighter and thinner, the specifications of PCB micro-drills are also getting smaller and smaller, and the corresponding precision requirements for micro-drilling and grinding equipment are also increasing. higher. The main equipment for PCB micro-drilling is a drill bit grinding machine. Drill bit processing involves multiple processes and processes. The bar is fixed in the fixture, and the bar is ground and shaped step by step through the grinding and cutting mechanism of each station. [0003] Due to the small specifications of PCB micro-drills, the grinding equipment has very high requirement...
