Abstract
The invention discloses an external expansion automatic centering type clamping device for annular workpiece drilling. The external expansion automatic centering type clamping device comprises a base with a fixing and bearing function, and further comprises a first disc spring and a second disc spring. The first disc spring is located internally and expands to abut against annular workpieces, and the second disc spring is located internally and expands to abut against drill plates. Disc spring gaskets, the first disc spring, the second disc spring and a disc spring pressing block are sequentially arranged on the upper side of the base. The drill plates for guiding drilling are arranged on the outer side of the second disc spring, and a core shaft penetrating the disc spring gaskets, the first disc spring, the second disc spring and the disc spring pressing block is fixedly arranged on the upper side of the center of the base. A gland nut is arranged at the top end of the core shaft through a thread, and a gasket is arranged between the gland nut and the disc spring pressing block. The external expansion automatic centering type clamping device has the following beneficial effects that design is reasonable, the structure is simple, and operation is convenient; locating precision is high, high universality is achieved, the labor intensity is low, and the workpieces are convenient to dismount and mount; and the service life of a clamp is long, production cost is low, and use and popularization are facilitated.
Description
Technical field
The invention belongs to Machining Technology field, relate to a kind of simple and easy fixture, be specifically related to one and extend outThe 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 bevel gear for automobile axle etc. Usually will be at its end face in the production process of circle ring partsProcess a lot of screwed holes, the position accuracy demand of these screwed holes is very high, and routine is looked for by lineScrewed hole positional precision cannot meet the requirement of its machining accuracy, and by the work of line thread mill drillingOrder complexity, labor strength is large, and production efficiency is low.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency of the prior art, provide one to extend out automatically fixedThe boring clamping device of core type annular work piece, it is reasonable in design, simple in structure, easy to operate, locationPrecision is high, highly versatile, and labour intensity is low, workpiece easy accessibility, fixture long service life, producesCost is low, is convenient to promote the use of.
For achieving the above object, the technical solution used in the present invention is: one extends out self-centering type ringShape Workpiece boring clamping device, has comprised and it is characterized in that the base of fixing carrying effect: also bagDraw together from positioned internal and expand and hold out against the dish spring one of annular work piece and hold out against brill from positioned internal expansionThe dish spring two of template; Described base upside is disposed with disc spring pad circle, dish spring one, dish spring two and butterflySpring briquetting, described dish spring two arranged outside are useful on the bushing plate of pilot bore hole, described base centre bitBeing set up side is fixedly installed through described disc spring pad circle, described dish spring one, described dish spring two and described butterflyThe mandrel of spring briquetting, described mandrel top is provided with clamp nut by screw thread, described clamp nut withBetween described butterfly spring briquetting, be provided with packing ring.
The above-mentioned boring clamping device of self-centering type annular work piece that extends out, is characterized in that: described inPacking ring is open washer.
The above-mentioned boring clamping device of self-centering type annular work piece that extends out, is characterized in that: described inMandrel is welded on described base.
The present invention compared with prior art has the following advantages:
(1) it is reasonable in design that this extends out the boring clamping device of self-centering type annular work piece, structure letterSingle, the clamp nut that operating personnel only need tighten mandrel top can complete the clamping to workpiece, operationVery easy.
(2) this extends out the boring clamping device of self-centering type annular work piece and 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 extends out the boring clamping device use of self-centering type annular work piece, workpiece dismountingConvenient, and fixture long service life.
(4) this extends out a lot of parts of the boring clamping device of self-centering type annular work piece all very justIn producing, buying, 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.

Detailed description of the invention
One as shown in Figure 2 extends out the boring clamping device of self-centering type annular work piece, has comprisedThe base 1 of fixing carrying effect, also comprises from positioned internal and expands holding out against the dish spring of annular work piece 4One 6 and from positioned internal and expand and hold out against the dish spring 27 of bushing plate 5; Described base 1 upside successivelyBe provided with disc spring pad circle 3, dish spring 1, dish spring 27 and butterfly spring briquetting 8, described dish spring 27 outsidesBe provided with the bushing plate 5 for pilot bore hole, described base 1 center upside is fixedly installed to be wornCross the core of described disc spring pad circle 3, described dish spring 1, described dish spring 27 and described butterfly spring briquetting 8Axle 2, described mandrel 2 tops are provided with clamp nut 9 by screw thread, described clamp nut 9 and instituteState between butterfly spring briquetting 8 and be provided with packing ring 10.
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 present invention extends out the boring clamping device of self-centering type annular work piece is: firstThis is extended out to the boring clamping device of self-centering type annular work piece and is fixed on Drilling machines bench, successivelyAnnular work piece 4 and bushing plate 5 are placed on base 1 through mandrel 2, tighten clamp nut downwards9, clamp nut 9 drives butterfly spring briquetting 8 to compress dish spring 1 and dish spring 27, and dish spring 1 is to extending outExhibition holds out against annular work piece 4 from positioned internal expansion, and dish spring 27 is also swollen to external expansion from positioned internalThe swollen bushing plate 5 that holds out against. After the hole processing of annular work piece 4 end faces completes, unclamp clamp nut9, dish spring 1 and dish spring 27 shrink automatically, thereby can be easily by annular work piece 4 and bushing plate 5Take off.
The above, be only preferred embodiment of the present invention, not the present invention imposed any restrictions, allAny simple modification, change and the equivalence of above embodiment being done according to the technology of the present invention essenceStructural Transformation, all still belongs in the protection domain of technical solution of the present invention.
