Abstract
The invention discloses a clamping tool for a cylinder-type workpiece. When the clamping tool for the cylinder-type workpiece is worked, the cylinder-type workpiece is embedded in a center hole of a tensioning sleeve. When an adjustable bolt is tightened, a piston compresses liquid plastics. The expansion of the liquid plastics forces the inner hole to expand inwards so that the workpiece is clamped. The clamping tool for the cylinder-type workpiece has the advantages of being strong in clamping force and good in centering effects.
Description
Technical field
The present invention relates to a kind of clamping tool, belong to the lathe tensioning technique, specifically a kind of cylinder type Workpiece clamping instrument.
Background technology
At present, mostly the fixture that is usually used in clamping the cylinder type workpiece is centering chuck, although centering chuck has versatility advantage preferably, but during due to its clamping work pieces be generally the two ends clamping from workpiece, workpiece for long easily causes bias, affects the crudy of workpiece, to this, go back at present neither one solution preferably.
Summary of the invention
The present invention is directed to existing centering chuck existing, clamp long workpiece, easily cause bias, affect the defective of the crudy of workpiece, the invention provides a kind of cylinder type Workpiece clamping instrument, it is larger that this kind cylinder type Workpiece clamping instrument has clamping force, and the centering effect is advantage preferably, can effectively overcome the existing existing defects of centering chuck.
the present invention realizes that the technical scheme that above-mentioned purpose adopts is: this invention comprises clamp body, adjusting bolt, piston, groove, liquid plastics, expansion sleeve, sealing ring, right locating flange, bolt, left locating flange, the cylindrical of described expansion sleeve is provided with the groove of annular, expansion sleeve is fixed in the intermediate throughholes of clamp body, be filled with liquid plastics between groove and clamp body, each seals between with a sealing ring and clamp body at the two ends of expansion sleeve, each fixes a left locating flange and right locating flange with bolt at the two ends, left and right of clamp body, left locating flange and right locating flange are with the expansion sleeve axial restraint, on the cylindrical of clamp body one end, adjusting bolt is installed, bottom centre's position fixed piston of adjusting bolt, piston communicates with the cavity that stores liquid plastics.
In when work, the workpiece of cylinder dress is packed in the interstitial hole of expansion sleeve, when tightening adjusting bolt, piston will compress liquid plastics, and the expansion of liquid plastics will force the endoporus of expansion sleeve to intramedullary expansion, and then with Workpiece clamping.
Beneficial effect: it is larger that the present invention has clamping force, and the centering effect is advantage preferably, can effectively overcome the existing existing defects of centering chuck.
