Description

A kind of fixture being exclusively used in irregular work pieces process
Technical field
The utility model relates to a kind of fixtures for being exclusively used in irregular work pieces process.
Background technique
It when being processed to workpiece, is typically necessary and is fixed workpiece by fixture, then fixture and processing platform are connected Capable processing is tapped into, unloads fixture together with workpiece after completion.But since structure is complicated for some workpiece, and shape is not Rule, operation of the existing fixture when it is fixed is relatively complicated, and the stability of clamping workpiece is poor, is easy to cause Workpiece generates error in process, or even scraps.
Utility model content
The purpose of this utility model is to provide a kind of fixture for being exclusively used in irregular work pieces process, structurally reasonable, energy The effectively clamping irregular workpiece of shape, and clamping stability is higher.
To achieve the above object, the technical solution of the utility model is to design a kind of folder for being exclusively used in irregular work pieces process Tool, the workpiece includes annular body, which has been uniformly arranged in the circumferential direction several small column convex blocks;The fixture Including pedestal in the form of annular discs, the pedestal be equipped with small column convex block several positioning pins correspondingly, at the top of each positioning pin Equipped with the pressing groove protruded into for corresponding small column convex block, it is equipped with pressing plate above the pressing groove, is equipped with the first locking in the pressing plate Screw, the pressing groove slot bottom are equipped with the first threaded hole cooperated with the first lock-screw;Support is equipped with right above the pedestal Plate, the support plate include three support legs, and three support legs are in same level and Y-shaped distribution, two neighboring support Angle between foot is 120 degree.
Preferably, it is equipped with conical through-hole at the support plate center, conical core shaft is installed in the conical through-hole, the taper It is equipped with through-hole at mandrel center, the second lock-screw is equipped in the through-hole, and the through-hole wall is equipped with the second locking screw of support The radial flange of nail head;Be equipped with the mounting groove that protrudes into for conical core shaft at the base center, the mounting groove slot bottom be equipped with Second threaded hole of the second lock-screw connection.
Preferably, it is additionally provided with the spring being sleeved on outside the second lock-screw in the through-hole, which is located at radial convex Between edge and mounting groove slot bottom.
Preferably, lightening hole there are three setting on the pedestal, single lightening hole is between two neighboring support leg.
The working principle of the utility model are as follows: when clamping, workpiece is placed on the positioning pin of bottom plate, and small on workpiece Cylinder convex block protrudes into the pressing groove of corresponding positioning pin, then installs pressing plate, is supported jointly by positioning pin and small column convex block Pressing plate is pressed on pressing plate in pressing groove small column convex block, so that workpiece be fixed by tightening the first lock-screw.Separately Outside, by the way that support plate, support plate and the coaxial heart of pedestal are arranged right above pedestal, and support plate is located on the inside of workpiece, by supporting Three support legs of plate are contacted with workpiece inner wall respectively, play the role of support workpiece, avoid workpiece in process because The deformation that rigidity is insufficient and generates;Also, the height of adjustable support plate, to improve the support effect of support plate;By tightening Second lock-screw can be such that conical core shaft and support plate moves down, and spring is compressed at this time;When unscrewing the second lock-screw, taper Mandrel moves up under the elastic restoring force effect of spring with support plate together.
The utility model has the following beneficial effects: the irregular workpiece of shape can effectively be clamped, and clamping stability is higher;Separately Outside, by the way that lightening hole is arranged, the weight of pedestal is effectively alleviated, to mitigate the overall weight of fixture.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model.
Fig. 2 is the schematic diagram of support plate in the utility model.
Fig. 3 is the schematic diagram of the utility model in the base and support plate connection structure.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is further described.Implement below Example is only used for clearly illustrating the technical solution of the utility model, and cannot be used as a limitation the protection model of limitation the utility model It encloses.
The technical solution of the utility model specific implementation is:
As shown in Figure 1, Figure 2 and Figure 3, a kind of fixture being exclusively used in irregular work pieces process, the workpiece include cyclic annular sheet Body 1,1 outer wall of annular body have been uniformly arranged in the circumferential direction several small column convex blocks 2;The fixture includes pedestal in the form of annular discs 3, the pedestal 3 be equipped with the one-to-one several positioning pins 4 of small column convex block 2, be equipped with for corresponding roundlet at the top of each positioning pin 4 The pressing groove 5 that column convex block 2 protrudes into is equipped with pressing plate 6 above the pressing groove 5, is equipped with the first lock-screw 7 in the pressing plate 6, described 5 slot bottom of pressing groove is equipped with the first threaded hole cooperated with the first lock-screw 7;Support plate 8 is equipped with right above the pedestal 3, it should Support plate 8 includes three support legs, and three support legs 9 are in same level and Y-shaped distribution, two neighboring support leg 9 Between angle be 120 degree.
It is equipped with conical through-hole 10 at above-mentioned 8 center of support plate, conical core shaft 11 is installed in the conical through-hole 10, the taper It is equipped with through-hole at 11 center of mandrel, the second lock-screw 12 is equipped in the through-hole, and the through-hole wall is equipped with the second lock of support The radial flange 13 on tight 12 head of screw;The mounting groove 14 protruded into for conical core shaft 11, the installation are equipped at 3 center of pedestal 14 slot bottom of slot is equipped with the second threaded hole 15 connecting with the second lock-screw 12.
