According to the sleeve type workpiece fixture, manpower is saved by means of the spiral-oblique wedge strengthening principle; workpieces in a certain size range can be clamped through the oblique wedge clamping mechanism, and the cost is saved; the uniform motion of the oblique wedges meets the concentricity requirement for the outer circle of the workpiece and the inner hole.

Description

A kind of sleeve workpiece fixture
Technical field
The design relates to a kind of sleeve workpiece fixture, belongs to machining fixture technical field.
Background technology
In recent years, the product of Multi-varieties and Small-batch Production grows with each passing day, and as the indispensable technological equipment of manufacturing industry, the flexibility of jig, greenization become a main direction of modern fixture.Fixture in the past often adopts mode manually, but the disadvantage of manual is: be subject to the restriction of staff active force, clamp power is less, has restricted the scope of application of manual.Meanwhile, different sleeve workpieces needs different fixtures, not only affects efficiency, has also increased production cost.
Summary of the invention
For the deficiencies in the prior art, the design's object is to provide a kind of sleeve workpiece fixture, utilizes wedge shifting principle, not only can process the sleeve workpiece within the scope of certain size, has also saved workman's labour intensity.
For achieving the above object, the design realizes by following technological means:
A kind of sleeve workpiece fixture, is characterized in that: described fixture is made up of mandrel, back-moving spring, two above wedge, voussoir fairlead, briquetting, packing ring and nuts; Described mandrel one end is provided with fixing block, and voussoir fairlead profile is conical, and voussoir fairlead is placed on mandrel, and one end contacts with block; More than two wedges are between voussoir fairlead and sleeve workpiece endoporus, and the taper shape of one side for matching with voussoir fairlead taper seat, is simultaneously the circular arc matching with sleeve workpiece endoporus, between more than two wedges and block, is provided with back-moving spring; Briquetting is the disk with the middle perforate of annular protrusion, and the annular protrusion of briquetting is pressed on wedge end face, and packing ring is positioned at briquetting outer end, tightens intrinsic nut at packing ring.
Preferably, described a kind of sleeve workpiece fixture, is characterized in that: the quantity of described wedge is four.
Preferably, described a kind of sleeve workpiece fixture, is characterized in that: the annular protrusion of described briquetting and the contact-making surface of wedge are circular arc.
Preferably, described a kind of sleeve workpiece fixture, is characterized in that: described packing ring is open washer.
The invention has the beneficial effects as follows: the design is by utilizing spiral--inclined wedge augmenting principle, after the secondary reinforcement of spiral and wedge, can obtain larger reinforcement coefficient, solve Manual clamping mechanism clamping force less
Problem, and can partly substitute the higher hydraulic and pneumatic clamp mechanism of power consumption, comply with the demand for development of manufacturing technology greenization; This fixture adopts oblique-wedge clamping system, all can clamp the workpiece within the scope of certain size, meets the designing requirement of flexible fixture; Fixture adopts four wedge constant speed movement principles, meets the technical requirement of excircle of workpiece and endoporus axiality.
Brief description of the drawings
Fig. 1 is that the design embodiment forms structural representation.
The implication of drawing reference numeral is as follows: 1 mandrel, 2 back-moving springs, 3 workpiece, 4 wedges, 5 voussoir fairleads, 6 briquettings, 7 packing rings, 8 nuts, 9 blocks.
Detailed description of the invention
Below in conjunction with Figure of description, design is further described.
As shown in Figure 1, plant sleeve workpiece fixture, it is characterized in that: described fixture is made up of mandrel 1, back-moving spring 2, two above wedge 4, voussoir fairlead 5, briquetting 6, packing ring 7 and nuts 8; Described mandrel 1 one end is provided with fixing block 9, and voussoir fairlead 5 profiles are conical, and voussoir fairlead 5 is placed on mandrel 1, and one end contacts with block 9; Two above wedges 4 are between voussoir fairlead 5 and sleeve workpiece 3 endoporus, the taper shape of one side for matching with voussoir fairlead 5 taper seats, the circular arc of one side for matching with sleeve workpiece 3 endoporus, is provided with back-moving spring 2 between more than two wedges 4 and block 9; Briquetting 6 is the disk with the middle perforate of annular protrusion, and the annular protrusion of briquetting 6 is pressed on wedge 4 end faces, and packing ring 7 is positioned at briquetting 6 outer ends, tightens intrinsic nut 8 at packing ring 7.
Setting element and the clamping element of this fixture is integrated (4), and locates and clamp action and carry out simultaneously.Because adopting constant speed movement principle, location clamping element can relatively move simultaneously, thereby can make the deviation of workpiece divide equally, to reach the impact of eliminating workpiece positioning datum scale error, realize the accurate centering of workpiece, meet the technical requirement of excircle of workpiece and endoporus axiality.
Preferably, described a kind of sleeve workpiece fixture, is characterized in that: the quantity of described wedge 4 is four.
Preferably, described a kind of sleeve workpiece fixture, is characterized in that: the contact-making surface of the annular protrusion of described briquetting 6 and wedge 4 is circular arc.
Four wedges 4 and the contact site of workpiece 3 are processed into arc surface, this arc surface can increase the contact area of wedge 4 and workpiece 3, reduce to greatest extent the clamping force in workpiece unit are, reduce the error that causes workpiece deformation to produce due to clamping force and cutting force; Briquetting 6 and wedge 4 contacts site are processed into circular-arc, the thrust that briquetting 6 is applied wedge 4 is always horizontal direction; Use open washer 7 can make the lay day of workpiece significantly reduce.In addition, the lead angle a of nut 8 is less than the angle of friction between nut and mandrel, therefore fixture completely can self-locking.
Use manual wrench fastening nut 8, open washer 7 and briquetting 6 are moved to the left, promote four wedges, 4 constant speed ground and be moved to the left along circumferential uniform gathering sill on voussoir fairlead 5, four wedges 4 are along voussoir simultaneously
The outside constant speed movement of radial direction of fairlead 5, realizes location and the clamping of workpiece 3.When cover parts completes after the grinding of cylindrical, unscrew nut 8, rely on the elastic force of four back-moving springs 2 to promote four tiltedly simultaneously
Wedge 4 moves right along the gathering sill of voussoir fairlead 5, and workpiece 3 is released, can realize freely loading and unloading of workpiece.And in the time that larger change occurs for the axial length of workpiece or radial diameter size, only need to change the wedge of different size.The open washer 7 of setting up can make the lay day of workpiece significantly reduce.
More than show and described the design's general principle, principal character and advantage.The technical staff of the industry should understand; the design is not restricted to the described embodiments; the principle that the design is just described of describing in above-described embodiment and description; do not departing under the prerequisite of the design's spirit and scope; the design also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the design.The claimed scope of the design is defined by appending claims and equivalent thereof.
