Technical field
The utility model belongs to Machining Technology field, relates to a kind of Simple clamp, is specifically related to one and extends out the boring clamping device of self-centering type annular work piece.
Background technology
At present, round ring parts is as shown in Figure 1 widely used in the every field of national economy, as the bevel gear etc. in automobile axle.Usually a lot of screwed hole will be processed at its end face in the production process of circle ring parts, the position accuracy demand of these screwed holes is very high, the screwed hole positional precision of looking for conventionally by ruling cannot meet the requirement of its machining accuracy, and pass through the complex procedures of line thread mill drilling, labor strength is large, and production efficiency is low.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, there is provided one to extend out the boring clamping device of self-centering type annular work piece, it is reasonable in design, and structure is simple, 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 adopted in the utility model is: one extends out the boring clamping device of self-centering type annular work piece, comprise the base of fixing carrying effect, it is characterized in that: also comprised from positioned internal and the disc spring one that holds out against annular work piece and expand hold out against the disc spring two of bushing plate from positioned internal of expanding; Disc spring packing ring, disc spring one, disc spring two and disc spring briquetting is disposed with on the upside of described base, described disc spring two arranged outside has the bushing plate for pilot bore hole, the mandrel through described disc spring packing ring, described disc spring one, described disc spring two and described disc spring briquetting is fixedly installed on the upside of described base center, described mandrel top is provided with clamp nut by screw thread, is provided with packing ring between described clamp nut and described disc spring briquetting.
Above-mentioned extends out the boring clamping device of self-centering type annular work piece, it is characterized in that: described packing ring is open washer.
Above-mentioned extends out the boring clamping device of self-centering type annular work piece, it is characterized in that: described mandrel is connected on described base.
The utility model compared with prior art has the following advantages:
(1) this to extend out the boring clamping device of self-centering type annular work piece reasonable in design, structure is simple, and the clamp nut that operating personnel only need tighten mandrel top can complete the clamping to workpiece, operates very easy.
(2) this extends out the boring clamping device of self-centering type annular work piece and uses the flexible location of disc spring, and thus positioning precision is high, highly versatile, and operator's labour intensity is very low.
(3) this extends out self-centering type annular work piece boring clamping device when using, workpiece easy accessibility, and fixture long service life.
(4) this extend out a lot of parts of the boring clamping device of self-centering type annular work piece be convenient to all very much produce, buy, thus its production cost is very low, is convenient to promote the use of.
Below by drawings and Examples, the utility model is described in further detail.

Detailed description of the invention
One as shown in Figure 2 extends out the boring clamping device of self-centering type annular work piece, comprise the base 1 of fixing carrying effect, also comprised from positioned internal and the disc spring 1 that holds out against annular work piece 4 and expand hold out against the disc spring 27 of bushing plate 5 from positioned internal of expanding; Disc spring packing ring 3, disc spring 1, disc spring 27 and disc spring briquetting 8 is disposed with on the upside of described base 1, described disc spring 27 arranged outside has the bushing plate 5 for pilot bore hole, the mandrel 2 through described disc spring packing ring 3, described disc spring 1, described disc spring 27 and described disc spring briquetting 8 is fixedly installed on the upside of described base 1 center, described mandrel 2 top is provided with clamp nut 9 by screw thread, is provided with packing ring 10 between described clamp nut 9 and described disc spring briquetting 8.
In the present embodiment, described packing ring 10 is open washer.
In the present embodiment, described mandrel 2 is welded on described base 1.
The course of work that the utility model extends out the boring clamping device of self-centering type annular work piece is: first this is extended out the boring clamping device of self-centering type annular work piece and be fixed on Drilling machines bench, successively annular work piece 4 and bushing plate 5 are placed on base 1 through mandrel 2, tighten clamp nut 9 downwards, clamp nut 9 drives disc spring briquetting 8 to compress disc spring 1 and disc spring 27, disc spring 1 is to external expansion from positioned internal and expansion holds out against annular work piece 4, and disc spring 27 is to external expansion from positioned internal and expansion holds out against bushing plate 5.After the hole processing of annular work piece 4 end face completes, unclamp clamp nut 9, disc spring 1 and disc spring 27 are shunk automatically, thus can easily annular work piece 4 and bushing plate 5 be taken off.
The above; it is only preferred embodiment of the present utility model; not the utility model is imposed any restrictions; every above embodiment is done according to the utility model technical spirit any simple modification, change and equivalent structure transformation, all still belong in the protection domain of technical solutions of the utility model.
