Abstract

The utility model relates to a reusable milling cutter device of printed circuit board for recycling. The utility model mainly recycles, renovates and rubs a knife edge part of the printed circuit board to form a shaft with a smaller diameter and a cutting groove on the shaft. The length of the edge part remains as valid cutting length which conforms to the specifications of a cutting diameter. One terminal of a shortened shank part is grinded into a convex jointed part with a smaller diameter. The convex jointed part is positioned with a socket jointed extending seat which has the same external diameter as the shank part. The utility model is characterized in that the shank part can be positioned directly by holding jaw to clamp a previous bar. The design of the socket jointed extending seat is favourable for highly accurate cutting operation, which can save up manufacturing cost.

Description

The printed circuit board (PCB) milling cutter device of tool regeneration

The utility model relates to a kind of printed circuit board (PCB) milling cutter device of tool regeneration.

General printed circuit board (PCB) milling cutter is made by the rod of the tungsten carbide material of high rigidity, the wearing and tearing at its blade position of causing after implementing the cutting bore operation on the printed circuit board base board, its printed circuit board (PCB) milling bit just can't re-use and become waste product, just it is abandoned, need to change new printed circuit board (PCB) milling cutter of assembling and cut bore operation again, so with regard to printed circuit board (PCB) milling cutter material cost, because tungsten carbide material cost costliness, upgrade one group of printed circuit board (PCB) milling cutter so again, manufacturing cost for the induced labor industry has just increased burden virtually, this is that this printed circuit board base board manufacturing cost that secondary industry faces can't reduce the scarce fraud that will increase cost at present, is necessary to be improved in fact.

Colleague's industry is in order to improve the shortcoming that is suitable for again behind the above-mentioned printed circuit board (PCB) cutter wear, and the problem that solves the increase of renewal printed circuit board (PCB) manufacturing cost that milling cutter brings, be to propose a kind of printed circuit board (PCB) milling cutter scrap to reclaim the mode of use again, as shown in Figure 1, it is rebuild blade position 11 damaged locations that reclaim printed circuit board (PCB) milling cutter 10 to polish, reach handle of a knife position 12 is processed 13 regenerations that cut groove, and blade position 11 sockets one gripper sleeve 20 that polishes with trimming, cutter relieving shank position 12 and the new printed circuit board (PCB) milling cutter 10 of gripper sleeve 20 formation one tool with original specification product equal length are reached the printed circuit board (PCB) milling cutter and may be reclaimed the purpose of use again by articles for use.

Yet above-mentionedly be nested with the mode that printed circuit board (PCB) milling cutter 10 utilizes again that reclaims with gripper sleeve 20, on practical application is implemented, because of it is to be that a male and female is nested with fit system, quality of fit has error, male and female fit workpiece also can't reach the processing request that keeps certain butt joint concentricity, the printed circuit board (PCB) milling cutter 10 of relative recovery is placed in the gripper sleeve 20, just can not produce the situation of mutual skew in vertically not being a straight line after the actual cover group as shown in Figure 2, that is the phenomenon of concentricity skew, the jaw 50 of adding processing machine is held on the gripper sleeve 20, rather than directly be held on printed circuit board (PCB) milling cutter 10 bars of recovery, so implementing in the running, when printed circuit board (PCB) milling cutter 10 needs to do with the operation of high speed rotary transverse cuts, therefore have rotational instability, reach the phenomenon that easily causes once more breaking and influence cutting accuracy, cause the printed circuit board base board precision that cuts out very poor, process under the strict high-precision requirement of operation at printed circuit board base board for this industry, this kind mode can be had a greatly reduced quality on the enforcement effect on the contrary, applicability remains to be discussed, and does not attain ideal really.

In view of this, this creator is based on the printed circuit board (PCB) milling cutter demand of printed circuit board base board secondary industry, improved at above-mentioned various shortcoming and problem, cooperate the experience that this industry is accumulated for many years of being engaged in, and innovate a kind of printed circuit board (PCB) milling cutter device of tool regeneration, be provided with this industry demand utilization.

Main purpose of the present utility model is to provide a kind of printed circuit board (PCB) milling cutter device of tool regeneration, and it makes printed circuit board (PCB) milling cutter scrap can reclaim use again, and then reaches the benefit of saving the processing and manufacturing cost.

Secondary objective of the present utility model is to provide a kind of printed circuit board (PCB) milling cutter device of tool regeneration, make its printed circuit board (PCB) milling cutter that is recycled to shape out blade position than minor diameter, be provided with utilizing once more and carry out cutting operation, and directly be clamped in the mode that applies on the former bar of printed circuit board (PCB) milling cutter at the jaw of the machine that can make tool in the practical operation, to reduce the fit tolerance of Assembed structural member, on process operations, can obtain preferable cutting stability relatively, and the cutting precision that can be applied with the printed circuit board (PCB) milling cutter of new product keeps equiconsistency, cause cutting precision to meet the requirements, have the effect of carrying out.

For achieving the above object, the utility model is achieved through the following technical solutions: a kind of printed circuit board (PCB) milling cutter device of tool regeneration is characterized in that; The blade position trimming that this recovery printed circuit board (PCB) milling cutter is damaged polishes into a shaft than minor diameter, having many thereon cuts groove, front end is for going out the cutting end, the length at blade position keeps meeting effective length of cut of cutting diameter specification, the handle of a knife position end of length reduction be shaped the less convex jointing part of diameter; The socket extending seat of the collocation one of this convex jointing part and handle of a knife position tool same outer diameter as, and draw the length of socket extending seat can be according to reclaiming the actual effective length of printed circuit board (PCB) milling cutter after the processing that is shaped and increasing and decreasing collocation.

This socket extending seat inside is provided with the endoporus that matches with the convex jointing part external form, and the aperture of this endoporus is the external diameter that is slightly less than convex jointing part, convex jointing part and affixed being integral of socket extending seat tight fit.

By the printed circuit board (PCB) milling cutter device of the utility model tool regeneration, overcome the shortcoming of prior art, reached the purpose of above-mentioned creation; The utility model makes printed circuit board (PCB) milling cutter scrap can reclaim use again, saves cost.

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
