Description
Technical field
The utility model relates to a kind of pneumatic quick change cylindrical clamping device.
Background technology
The sleeve workpiece processing tool probably has following several kinds at present:
1. use the cone mechanical grip; That is to say to move realize to clamp that shortcoming is that machining accuracy is difficult for guaranteeing through the cooperation of the conical surface, workpiece when clamping because tapered sleeve can drive workpiece when clamping moves; Axial location is inaccurate; Iron filings are prone to get between cone and the tapered sleeve simultaneously, have a strong impact on machining accuracy, generally only are used for semifinishing.
2. plastic thin wall cover clamps: in a rigidity elastic thin-wall cover, fill liquid plastics, plastics are exerted pressure, transmit pressure through flowing of plastics and make elastic thin-wall cover harmomegathus realize the clamping of workpiece and unclamp; Shortcoming is the thin-walled parts processing difficulties, and the plastics retraction is slow during clamping and release, and can not bounce back fully; So always high two ends, middle part are low; Increased the gap between workpiece endoporus and the thin-walled cover virtually, reduced machining accuracy, thin-walled cover frock is disposable; When changing frock, basically just scrapped; Boiling plastics also is a complicated work, and plastic quality is boiled personnel and weather effect is bigger.
3. plastic clamp adds retinue cover jig: this jig generally is used for dry cylinder liner processing; It has utilized the plastic clamp advantage of high precision; High two ends are low in the middle of when having overcome the plastic clamp clamping simultaneously; The clamping force imbalance problem, but the retinue cover must cut when using, because the heat-treated deformation effect has reduced machining accuracy.
The utility model content
The utility model provides a kind of fast changeable, pneumatic quick change cylindrical clamping device that precision is high.
In order to solve the problems of the technologies described above; The utility model adopts following technical scheme: pneumatic quick change cylindrical clamping device; The body that comprises cylindricality; The body outside is arranged with elasticity quick change cover and clamp, and elasticity quick change cover is through alignment pin and body-fixed, and elasticity quick change cover is communicated with compressed air source through air supply system with cavity between the body.
Described air supply system comprises that the body center is provided with the axial compression air duct that is communicated with compressed air source vertically, and the body of the inner of axial compression air duct is provided with joint, and the outer end of axial compression air duct is provided with obstruction; Radially be provided with the radial compression air duct on the body, the radial compression air duct is inner to be communicated with the axial compression air duct, the outer end of radial compression air duct overlap with the elasticity quick change and body between cavity be connected.
The madial wall of described elasticity quick change cover is provided with the air drain of depression.
The two ends of the madial wall of described elasticity quick change cover are provided with sealing ring.
The outside wall body at described elasticity quick change cover two ends is provided with cone tank, is provided with spring in the cone tank.
The utility model can be realized the quick switching of different product, changes product and only need change elasticity quick change cover, adapts to different product and switches; And precision is high; Realize location and clamping separately through the clamp in the elasticity quick change cover; Step up cover and add the man-hour inside and outside circle and once clamp simultaneously processing and guaranteed to have improved positioning accuracy by internal-external circle concentricity, adopt special processing both to guarantee the clamping force equilibrium between the clamp in elasticity quick change cover and the cover; Comparing with casual cover frock does not also need to cut, and has reduced the distortion of elasticity quick change cover.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Embodiment: as shown in Figure 1; Pneumatic quick change cylindrical clamping device; The body 4 that comprises cylindricality; Body 4 outsides are arranged with elasticity quick change cover 5 and clamp, and elasticity quick change cover 5 is fixing with body 4 through alignment pin 3, and elasticity quick change cover 5 is communicated with compressed air source through air supply system with cavity between the body 4.
Air supply system comprises that the body center is provided with the axial compression air duct that is communicated with compressed air source vertically, and the body 4 of the inner of axial compression air duct is provided with joint 1, and the outer end of axial compression air duct is provided with stops up 8; Radially be provided with the radial compression air duct on the body 4, the radial compression air duct is inner to be communicated with the axial compression air duct, the outer end of radial compression air duct and elasticity quick change overlap 5 and body 4 between cavity be connected.The madial wall of elasticity quick change cover 5 is provided with the air drain of depression.The two ends of the madial wall of elasticity quick change cover 5 are provided with sealing ring 7.The outside wall body that the elasticity quick change overlaps 5 two ends is provided with cone tank, is provided with spring 2 in the cone tank.
Operation principle: compressed air gets into body 4 middle parts through joint 1 during clamping; Clamp in the elasticity quick change cover 5 evenly swells clamping work pieces 6 under air pressure; Elasticity quick change cover 5 is used little matched in clearance through alignment pin 3 and body 4 relative fixed between elasticity quick change cover 5 and the body 4, mainly is to realize changing fast frock through changing elasticity quick change cover 5; Adapt to the different product requirement, be added with O RunddichtringO 7 in order to be sealed between elasticity quick change cover 5 and the body 4; Unclamp, compressed air removes the clamp retraction under spring 2 effects in the back elasticity quick change cover 5, and workpiece unclamps.
It is high that elasticity quick change cover 5 need not cut time processing moulding internal-external circle concentricity precision, and the clamps in the elasticity quick change cover 5 are through slow silk thread cutting one-shot forming, not only guaranteed positioning accuracy but also can balanced clamping work pieces, and the big workpiece deformation of clamping area is little.Be designed to a cone tank to spring groove, guarantee spring and elasticity quick change cover 5 and the tangent always realization high accuracy of clamp axial location in the clamp relative motion process in elasticity quick change cover 5 and elasticity quick change overlap.Elasticity quick change cover is designed to eccentric the clamping with clamp in the cover, not only can reduce clamping pressure but also can guarantee clamp the air-tightness between overlapping with the elasticity quick change.
