Abstract
The utility model discloses a clamping tool for a cylindrical workpiece. A tensioning sleeve is fixed in a middle through hole of a clamping body, liquid plastic is filled between a groove and the clamping body, the two ends of the tensioning sleeve and the clamping body are respectively sealed by a seal ring, an adjusting bolt is mounted on the outer circle at one end of the clamping body, a piston is fixed in the center of the bottom of the adjusting bolt, and the piston is communicated with a cavity for storing the liquid plastic. The clamping tool for the cylindrical workpiece has the advantages of greater clamping force and better centering effect.
Description
Technical field
The utility model relates to a kind of clamping tool, belongs to the lathe tensioning technique, a kind of specifically cylinder type workpiece clamp clamping tool.
Background technology
At present, mostly the anchor clamps that are usually used in clamping the cylinder type workpiece are centering chuck, though centering chuck has versatility advantage preferably; But during owing to its clamping work pieces generally be two ends clamping from workpiece; Workpiece for long causes off-centre easily, influences the crudy of workpiece; To this, go back neither one solution preferably at present.
Summary of the invention
The utility model is existing to existing centering chuck; Clamp long workpiece, cause off-centre easily, influence the defective of the crudy of workpiece; The utility model provides a kind of cylinder type workpiece clamp clamping tool; It is bigger that this kind cylinder type workpiece clamp clamping tool has clamping force, and the centering effect is advantage preferably, can overcome the existing existing above-mentioned defective of centering chuck effectively.
The utility model realizes that the technical scheme that above-mentioned purpose adopted is: this utility model comprises clamp body, regulates bolt, piston, groove, liquid plastics, tensioner cover, sealing ring, right locating flange, bolt, left locating flange; The cylindrical of said tensioner cover is provided with the groove of annular; The tensioner cover is fixed in the intermediate throughholes of clamp body; Between groove and clamp body, be filled with liquid plastics, each seals between with a sealing ring and clamp body at the two ends of tensioner cover, and each fixes a left locating flange and right locating flange with bolt in the right ends of clamp body; Left side locating flange and right locating flange are axially fixing with the tensioner cover; The adjusting bolt is installed on the cylindrical of clamp body one end, regulates bottom centre's position fixed piston of 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 tensioner cover, when tightening when regulating bolt, piston will compress liquid plastics, and the expansion of liquid plastics will force endoporus that tensioner overlaps to intramedullary expansion, and then workpiece is clamped.
Beneficial effect: it is bigger to the utlity model has clamping force, and the centering effect is advantage preferably, can overcome the existing existing above-mentioned defective of centering chuck effectively.
Description of drawings
Fig. 1 is the structure principle chart of the utility model;
Shown in the figure: 1, clamp body; 2, regulate bolt; 3, piston; 4 grooves; 5, liquid plastics; 6, tensioner cover; 7, sealing ring; 8, right locating flange; 9, bolt; 10, left locating flange.
The specific embodiment
In the drawings; This utility model comprises clamp body 1, adjusting bolt 2, piston 3, liquid plastics 5, tensioner cover 6, sealing ring 7, right locating flange 8, bolt 9, left locating flange 10; The cylindrical of said tensioner cover 6 is provided with the groove 4 of annular, and tensioner cover 6 is fixed in the intermediate throughholes of clamp body 1, between groove 4 and clamp body 1, is filled with liquid plastics 5; Each seals between with a sealing ring 7 and clamp body 1 at the two ends of tensioner cover 6; With bolt 9 each fixing left locating flanges 10 and right locating flanges 8, left locating flange 10 overlaps 6 axial restraints with right locating flange 8 with tensioner, on the cylindrical of clamp body 1 one ends, is equipped with to regulate bolt 2 in the right ends of clamp body 1; Regulate bottom centre's position fixed piston 3 of bolt 2, piston 3 communicates with the cavity that stores liquid plastics 5.
In when work, the workpiece of cylinder dress is packed in the interstitial hole of tensioner cover 6, when tightening when regulating bolt 2, piston 3 will compress liquid plastics 5, and the expansion of liquid plastics 5 will force tensioner to overlap 6 endoporus to intramedullary expansion, and then workpiece is clamped.
