Abstract
The utility model discloses an improved three-jaw chuck which includes a chuck body and three jaws with same structure; each jaw consists of a jaw connecting seat and a jaw clamping part fixedly connected inside the jaw connecting seat; the jaw clamping part is provided with a swallow-tailed groove; the chute body is fixedly connected with two bolt seats spaced with the three jaws; each bolt seat is provided with supporting columns which are connected by threads; and the extended line of the middle line of each supporting column is crossed with the central line of the chuck body. The improved three-jaw chuck adopting the structure is convenient to be used, can avoid slippage when clamping workpiece blank, and improves the yield of turning.
Description
Technical field
The utility model relates to turning attachment, relates in particular to a kind of improved scroll chuck.
Background technology
The machined into workpiece uses scroll chuck usually, scroll chuck commonly used comprises chuck body and three claws, in use since workpiece blank have be the polymorphic structure of similar equilateral triangle shape, the sliding phenomenon of blank pine in the time of can appearing at holding workpiece influences the qualification rate of machined into.
The utility model content
Technical problem to be solved in the utility model is: a kind of improved scroll chuck is provided, and the improved scroll chuck of this kind can avoid the holding workpiece blank the sliding phenomenon of pine to occur, improves the qualification rate of machined into.
Solve this technical problem, the technical solution of the utility model is: a kind of improved scroll chuck, the claw that comprises chuck body and three same structures, described each claw is formed by claw Connection Block and the claw clamping part that is fixed in claw Connection Block inboard, described claw clamping part has swallow-tailed groove, be connected with on the described chuck body and three isolated two bolt blocks of claw, each bolt block is provided with the support column that is threaded, and the extended line of the center line of described each support column and the center line of chuck body intersect.
The swallow-tailed groove of the claw clamping part of described each claw is provided with the claw clamping cushion block of symmetry.
The angle that the dovetail shaped groove of described claw clamping part forms is 130 degree.
A kind of improved scroll chuck of the utility model adopts such structure, and is simple in structure, easy to use, can avoid the holding workpiece blank the sliding phenomenon of pine to occur, improved the qualification rate of machined into.
Description of drawings
Fig. 1 is the structural representation of a kind of improved scroll chuck of the utility model;
In Fig. 1,1, chuck body; 2, claw clamping cushion block; 3, claw Connection Block; 4, claw clamping part; 5, first bolt block; 6, first support column; 7, second support column; 8, second bolt block.
The specific embodiment
As shown in Figure 1, a kind of improved scroll chuck, the claw, first bolt block 5, first support column 6, second bolt block 8 and second support column 7 that comprise chuck body 1, three same structures, each claw is formed by claw Connection Block 3 and the claw clamping part 4 that is fixed in claw Connection Block 3 inboards, claw clamping part 4 has swallow-tailed groove, the claw clamping cushion block 2 that has symmetry on the swallow-tailed groove of the claw clamping part 4 of each claw, the angle that the dovetail shaped groove of claw clamping part 4 forms are selected 130 degree for use.First bolt block 5 and second bolt block 8 are fixed on the chuck body 1, and be spaced apart with three claws, do not interfere with each other.First support column 6 is threaded with first bolt block 5, the center line of the extended line of the center line of first support column 6 and chuck body 1 intersects, second support column 7 is threaded with second bolt block 8, and the center line of the extended line of the center line of second support column 7 and chuck body 1 intersects.Such structure, when the holding workpiece blank, three claws and two support columns all work, and can avoid the holding workpiece blank the sliding phenomenon of pine to occur, have improved the qualification rate of machined into.
