Abstract
The invention discloses an end face drilling clamp for circular ring parts. The end face drilling clamp for the circular ring parts comprises a base and a part locating gasket with the outer surface ground. The part locating gasket, a belleville spring gasket, a belleville spring and a belleville spring pressing block are sequentially arranged at the upper side of the base. A mandrel penetrating through the part locating gasket, the belleville spring gasket, the belleville spring and the belleville spring pressing block is fixedly installed in the middle of the base. The top end of the mandrel is provided with a compression nut. The end face drilling clamp for the circular ring parts has the following advantages of being reasonable in design, simple in structure, convenient to operate, high in locating accuracy, strong in generality, low in labor intensity, capable of enabling a workpiece to be disassembled and assembled conveniently, long in service life, low in production cost and convenient to popularize and use.
Description
Technical field
The invention belongs to Machining Technology field, relate to a kind of fixture, be specifically related to a kind of annulus class part end face boring grab.
Background technology
At present, round ring parts is as shown in Figure 1 widely used in the every field of national economy, as bevel gear for automobile axle etc.In the production process of circle ring parts, usually will process a lot of screwed holes at its end face, the position accuracy demand of these screwed holes is very high, now conventionally uses Digit Control Machine Tool to complete the processing of screwed hole.Using Digit Control Machine Tool double thread hole to add man-hour, conventionally adopt scroll chuck clamping outer surface, in the time using scroll chuck clamping circle ring parts outer surface, because the clamping force of scroll chuck can leave impression at circle ring parts outer surface, thereby the surface quality of impact circle ring parts, and the versatility of scroll chuck is not strong.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency of the prior art, a kind of annulus class part end face boring grab is provided, and it is reasonable in design, simple in structure, easy to operate, positioning precision is high, highly versatile, and labour intensity is low, workpiece easy accessibility, fixture long service life, production cost is low, is convenient to promote the use of.
For achieving the above object, the technical solution used in the present invention is: a kind of annulus class part end face boring grab, comprise base and the outer surface part space washer through grinding, it is characterized in that: described base upside is disposed with part space washer, butterfly spring packing ring, butterfly spring and butterfly spring briquetting, described base middle part is installed with the mandrel through part space washer, butterfly spring packing ring, butterfly spring and butterfly spring briquetting, and described mandrel top is provided with clamp nut.
Above-mentioned annulus class part end face boring grab, is characterized in that: between described clamp nut and butterfly spring briquetting, be provided with open washer.
Above-mentioned annulus class part end face boring grab, is characterized in that: described mandrel is fixedly mounted on base by screw.
The present invention compared with prior art has the following advantages:
(1) this annulus class part end face boring grab is reasonable in design, simple in structure, and the clamp nut that operating personnel only need tighten mandrel top can complete the clamping to workpiece, operates very easy.
(2) this annulus class part end face boring grab uses the flexible location of butterfly spring, thereby positioning precision is high, highly versatile, and operator's labour intensity is very low.
(3) when this annulus class part end face boring grab uses, workpiece easy accessibility, and fixture long service life.
(4) a lot of parts of this annulus class part end face boring grab are all convenient to produce, buy very much, thereby its production cost is very low, is convenient to promote the use of.
Below by drawings and Examples, the present invention is described in further detail.

The specific embodiment
A kind of annulus class part end face boring grab as shown in Figure 2, comprise base 1 and the outer surface part space washer 2 through grinding, described base 1 upside is disposed with part space washer 2, butterfly spring packing ring 3, butterfly spring 4 and butterfly spring briquetting 6, described base 1 middle part is installed with the mandrel 5 through part space washer 2, butterfly spring packing ring 3, butterfly spring 4 and butterfly spring briquetting 6, and described mandrel 5 tops are provided with clamp nut 8.
As shown in Figure 2, between described clamp nut 8 and butterfly spring briquetting 6, be provided with open washer 7.
As shown in Figure 2, described mandrel 5 is fixedly mounted on base 1 by screw 9.
The course of work of annulus class part end face boring grab of the present invention is: first this annulus class part end face boring grab is fixedly mounted on Digit Control Machine Tool table top by tommyhead bolt, then circle ring parts 10 is placed on part space washer 2 through mandrel 5, tighten clamp nut 8 downwards, clamp nut 8 drives butterfly spring briquetting 6 to compress butterfly spring 4, butterfly spring 4 is to external expansion, from inner surface tensioner circle ring parts 10.After end face has been holed, unclamp clamp nut 8, butterfly spring 4 shrinks automatically, thereby can easily circle ring parts 10 be taken off.
The above; it is only preferred embodiment of the present invention; not the present invention is imposed any restrictions, every any simple modification, change and equivalent structure transformation of above embodiment being done according to the technology of the present invention essence, all still belongs in the protection domain of technical solution of the present invention.
