Abstract
A detachable simple soft claw is characterized in that three copper annular soft claws (3) are fastened on three hard claws (2) through bolts by means of a three-claw self-centering chuck (1) and the hard claws (2) of a machine tool, and the copper annular soft claws (3) may rotate together with the hard claws (2). The annular soft claws (3) may also be made of steel, and a workpiece (5) can be disposed in the three annular soft claws (3) and is fastened through the centering chuck (1). The soft claw has the advantages of simple structure, low manufacture cost, mass and standard production, convenient installation and no need for detaching and re-equipping the chuck and hard claws of the machine tool, and is specifically suitable for small and miniature thin-wall workpieces.
Description
Technical field
The utility model belongs to machined clamping tool technical field, refers more particularly to a kind of detachable simple and easy soft pawl.
Background technology
In turning processing, generally use three-jaw self-centering chuck and four-jaw chuck clamping workpiece, particularly when processing with the cylindrical is location benchmark thin-wall workpiece, because clamping force makes workpiece easily produce distortion.In order to prevent the thin-wall workpiece distortion, being extensive use of soft dog chuck at present clamps, being about to the hard pawl of three-jaw self-centering chuck unloads, change a pair without the autocratic soft pawl that hardens, or on the clamping face of old monoblock type claw, burn-on steel material or copper material, again claw is packed in the chuck, so jaw clamping face car is become and the same size of institute's processing work, the workpiece external diameter is contained clamping entirely, so that clamping force is uniformly distributed on the contact area of whole increase, reduced the clamping force of unit are, the clamping distortion of thin-wall workpiece is reduced.The claw that these two kinds of clampings are used can only use once by a kind of workpiece, and a whole set of after changing claw of workpiece needs all to change, and can not reuse, if workpiece frequently changes, the design and manufacture cost of claw is higher relatively.
Summary of the invention
In order to overcome above-mentioned weak point, the utility model has designed a kind of detachable simple and easy soft pawl, utilizes lathe to carry three-jaw self-centering chuck and the enforcement of hard pawl, and is repeatedly reusable.
For achieving the above object, the utility model adopts following technical scheme:
Described detachable simple and easy soft pawl carries three-jaw self-centering chuck and hard pawl by lathe, with three soft pawls of copper ring-type by bolted on three hard pawls, the soft pawl of copper annular can together rotate with hard pawl.
Described detachable simple and easy soft pawl, the soft pawl of its ring-type also can be that steel is done.
Owing to adopt aforesaid technical scheme, the utlity model has following good effect:
1, soft pawl is simple in structure, low cost of manufacture, standardized designs production in batch.
2, easy for installation, need not dismantle and reequip machine chuck and hard pawl.
3, repeatedly reusable, especially be suitable for small-sized and miniature thin walled workpieces.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is annular soft pawl structural representation;
Among the above-mentioned figure: 1-centering chuck; 2-hard pawl; 3-annular soft pawl; 4-bolt; 5-workpiece.
The specific embodiment
As shown in Figure 1, 2: detachable simple and easy soft pawl of the present utility model carries three-jaw self-centering chuck (1) and hard pawl (2) by lathe, three soft pawls of copper ring-type (3) are fastened on three hard pawls (2) by bolt (4), and the copper soft pawl of annular (3) can together rotate with hard pawl (2).The soft pawl of ring-type (3) also can be that steel is done, and then workpiece (5) is placed in three soft pawls of ring-type (3), and is fastening by centering chuck (1) again.
The utility model is simple in structure, low cost of manufacture, and standardized designs production in batch, easy for installation, need not dismantle and reequip machine chuck and hard pawl, especially be suitable for small-sized and miniature thin walled workpieces.
Claims (2)
1, a kind of detachable simple and easy soft pawl, carry three-jaw self-centering chuck (1) and hard pawl (2) by lathe, it is characterized in that: three soft pawls of copper ring-type (3) are fastened on three hard pawls (2) by bolt (4), and the copper soft pawl of annular (3) can together rotate with hard pawl (2).
2, detachable simple and easy soft pawl as claimed in claim 1, it is characterized in that: the soft pawl of ring-type (3) also can be that steel is done.
