Abstract

The utility model discloses a three-claw chuck, which comprises a chuck body and three clamping claws with a same structure. The chuck body is provided with a work-piece pressing mechanism which comprises a rectangular sliding seat, a small shaft and an eccentric hand wheel rotating around the small shaft, the rectangular sliding seat is provided with an upper open plate and a lower sliding strip which is parallel to the upper open plate and integrated with the same, the small shaft is fixed on the upper open plate of the rectangular sliding seat, the lower sliding strip shifts in a reciprocation manner along a rail groove disposed on the chuck body, and an extension line of a middle line of the rail groove on the chuck body intersects with a central line of the same. By adopting the structure, the three claw chuck has convenient utilization, can avoid loosening and slippage of clamped work-piece blanks, increases qualification rate of lathe processing, and enlarges range of the lathe processing.

Description

Scroll chuck
Technical field
The utility model relates to turning attachment, relates in particular to a kind of scroll chuck.
Background technology
The machined into workpiece uses scroll chuck usually, scroll chuck commonly used comprises chuck body and three claws, in use, be the polymorphic structure of similar equilateral triangle shape because workpiece blank has, the sliding phenomenon of blank pine when adding trade union appearing at holding workpiece on lathe influences the qualification rate of machined into.
The utility model content
Technical problem to be solved in the utility model is: a kind of scroll chuck is provided, and this kind scroll chuck 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 scroll chuck, the claw that comprises chuck body and three same structures, described chuck body is provided with workpiece pressing mechanism, this workpiece pressing mechanism comprises the shaped as frame slip base, little axle and the eccentric handwheel that rotates around little axle, described shaped as frame slip base has upper shed plate and the following slippage bar that fuse parallel with the upper shed plate, described little axle is fixed in the upper shed plate of shaped as frame slip base, the rail groove shift reciprocately that described down slippage bar is provided with on the chuck body, the extended line of the center line of the rail groove on the described chuck body and the center line of chuck body are crossing.
The arranged outside of the following slippage bar of described shaped as frame slip base has vertical rectangular opening, described upper shed plate has the support strip of the vertical rectangular opening of slippage bar under the putting in of downward extension, have the horizontal through hole at a plurality of intervals on the support strip, be provided with the bearing pin of connection between the support strip of described slippage bar down and upper shed plate.
Described each claw is formed by claw Connection Block and the claw clamping part that is fixed in claw Connection Block inboard, and described claw clamping part has swallow-tailed groove.
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.
The utility model scroll chuck 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, increased the machined into scope.
Description of drawings
Fig. 1 is the structural representation of the utility model scroll chuck;
Fig. 2 analyses and observe enlarged diagram for A-A shown in Figure 1;
In Fig. 1, Fig. 2,1, chuck body; 2, claw clamping cushion block; 3, claw Connection Block; 4, claw clamping part; 5, workpiece pressing mechanism; 6, rail groove; 7, following slippage bar; 8, bearing pin; 9, upper shed plate; 10, little axle; 11, eccentric handwheel.
The specific embodiment
As Fig. 1, shown in Figure 2, a kind of scroll chuck, the claw that comprises chuck body 1 and three same structures, described chuck body 1 is provided with workpiece pressing mechanism 5, this workpiece pressing mechanism 5 comprises the shaped as frame slip base, little axle 10 and the eccentric handwheel 11 that rotates around little axle 10, the shaped as frame slip base has upper shed plate 9 and the following slippage bar 7 that fuse parallel with upper shed plate 9, the arranged outside of the following slippage bar 7 of shaped as frame slip base has vertical rectangular opening, the upper shed plate 9 of shaped as frame slip base has the support strip of slippage bar 7 vertical rectangular openings under the putting in of downward extension, have the horizontal through hole at a plurality of intervals on the support strip of upper shed plate 9, the bearing pin 8 that has connection between the support strip of following slippage bar 7 and upper shed plate 9, little axle 10 is fixed in the upper shed plate 9 of shaped as frame slip base, rail groove 6 shift reciprocatelies that following slippage bar 7 is provided with on the chuck body 1, the extended line of the center line of the rail groove 6 of chuck body 1 and the center line of chuck body 1 are crossing.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 swallow-tailed groove of the claw clamping part of individual claw is provided with the claw clamping cushion block 2 of symmetry, and the angle that the dovetail shaped groove of pawl clamping part forms is 130 degree.
During use, earlier the spacing of shaped as frame slip base and chuck body is adjusted, again with the shaped as frame slip base along the outside translation of chuck body rail groove, the workpiece that will process is put on the scroll chuck then, three-jaw is inwardly closed up the workpiece that clamping will be processed, and then with the shaped as frame slip base along the inside translation of chuck body rail groove, the rotating eccentricity handwheel, the workpiece that will process clamps.Such structure has increased workpiece pressing mechanism, when the polymorphic structure workpiece of the similar equilateral triangle shape of clamping, can avoid the holding workpiece blank the sliding phenomenon of pine to occur, has increased the machined into scope, has improved the qualification rate of machined into.
