Abstract
The utility model discloses a two-jaw chuck which comprises a fixture body, cable-stayed piles, clamping blocks and a push block, wherein two cable-stayed piles are arranged in the fixture body and encircled by the fixture body; the matching surface of the cable-stayed pile and the fixture body is an inclined plane; one clamping block is fixedly arranged at the inner side of each cable-stayed pile; the two cable-stayed piles are connected with the push block; and the push block can drive the two cable-stayed piles to move along the axial direction of the fixture body. When the two-jaw chuck is used for clamping a workpiece, the jaws do not turnover outward; moreover, the jaws can generate radial clamping force as well as axial tension during workpiece clamping and have strong clamping force and stability, so that the axial positioning of the workpiece is more reliable.
Description
Technical field
The utility model relates to a kind of anchor clamps, is specifically related to a kind of two dog chucks.
Background technology
Existing hydraulic pressure two dog chucks comprise chuck seat, and the top movable of chuck seat is provided with two claws.During work, make two claws do radial motion with respect to chuck seat, until contacting with workpiece, and final clamping work pieces.Claw also is subjected to the reaction force of workpiece in clamping work pieces.
Owing to have the gap between claw and its guiding mechanism, and deformation can take place in claw under the reaction force of workpiece, therefore claw is under the double action of hydraulic pressure pulling force (or thrust) and workpiece reaction force, can be that initial point rotates with the root of claw, be that claw can become " eight " font, clamping work pieces is not the clamping face of claw just like this, but the contact of the line of claw root, the stability of claw clamping just greatly reduces like this.
In addition, because rotation has taken place in claw, then claw root (being the position of effective clamping work pieces) has outside component in the axial direction, cause the workpiece that originally leans against on the locating surface that displacement (from the inside to the outside) has taken place in the axial direction, and this displacement can be subjected to the influence of several factors, causes the location of workpiece also to become unstable.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of two dog chucks, and it can avoid claw to rotate in clamping process.
For solving the problems of the technologies described above, the technical solution of the utility model two dog chucks is:
Comprise clamp body, oblique stay column, clamp, pushing block, be provided with two oblique stay columns in the clamp body, clamp body is encircled oblique stay column, and tiltedly the mating surface of stay column and clamp body is the inclined-plane; The inboard of each oblique stay column is set with a clamp; Two oblique stay columns connect pushing block, and pushing block can drive the axially-movable of two oblique stay columns along clamp body.
Described two oblique stay columns are symmetrical arranged with respect to the center of clamp body.
Described clamp is fixedlyed connected with oblique stay column by screw.
The clamping area of described clamp inboard is a vertical plane.
The bottom of described clamp body is provided with the back shroud of the axial scope of activities of the oblique stay column of restriction.
Described clamp body is provided with pump nozzle.
The technique effect that the utility model can reach is:
Clamp body of the present utility model is an oblique stay column of encircling claw, thereby can effectively overcome the distortion that the workpiece reaction force produces, and claw just can not become " eight " font, makes holding workpiece more stable.And the component of axially-movable is the ecto-entad motion, and workpiece more stably is attached on the locating surface, makes the workpiece location more reliable.
The utility model is when clamping work pieces, and claw does not have the phenomenon of turning up, and claw both produced radially clamping force when holding workpiece, produces axial tension again, has very strong clamping force and stability, makes the axial location of workpiece more reliable.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the stereogram of the utility model two dog chucks;
Fig. 2 is a profile of the present utility model;
Fig. 3 is the vertical view of Fig. 2.
Description of reference numerals among the figure:
1 is clamp body, and 2 is oblique stay column,
3 is pushing block, and 4 is back shroud,
5 is clamp, and 6 is pump nozzle,
7 is screw.
The specific embodiment
As shown in Figure 1 to Figure 3, the utility model two dog chucks comprise clamp body 1, oblique stay column 2, clamp 5, pushing block 3, are symmetrically arranged with two oblique stay columns 2 in the clamp body 1, and clamp body 1 is encircled oblique stay column 2, and tiltedly stay column 2 is the inclined-plane with the mating surface of clamp body 1; The inboard of each oblique stay column 2 is set with a clamp 5, and clamp 5 is fixedlyed connected with oblique stay column 2 by screw 7;
The inboard of clamp 5 is a clamping area, and clamping area is a vertical plane;
The bottom of clamp body 1 is provided with back shroud 4, and back shroud 4 can limit the axial scope of activities of oblique stay column 2;
Two oblique stay columns 2 connect pushing block 3, and the tracks of pushing block 3 is the axial direction of clamp body 1.
Clamp body 1 is provided with pump nozzle 6.
During work, drive two oblique stay columns 2 by pushing block 3 and move downward, tiltedly two clamps 5 of stay column 2 drives are realized radial motion in opposite directions in the process that moves downward, until clamping work pieces.
Otherwise, promote two oblique stay columns 2 by pushing block 3 and move upward, tiltedly stay column 2 drives two clamps 5 and realize opposing radial motion in the process that moves upward, until unclamping workpiece.
Clamp of the present utility model (being claw) carries out radially in clamping process simultaneously, axially-movable, and radial motion realizes the clamping to workpiece.
