Description

Hydraulic chuck

Technical Field

The utility model relates to a chuck field especially relates to a hydraulic chuck.

Background

Chucks are mechanical devices used to clamp workpieces on machine tools. The machine tool accessory clamps and positions a workpiece by utilizing the radial movement of movable clamping jaws uniformly distributed on a chuck body. The chuck generally comprises a chuck body, movable jaws and a jaw driving mechanism 3. The chuck grips the workpiece during machining, but over time the front ends of the jaws wear, thus requiring replacement of the entire jaw.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that overcome exist among the prior art not enough, provide a hydraulic chuck.

The utility model discloses a realize through following technical scheme:

the utility model provides a hydraulic chuck, includes chuck body and sets up the clamping jaw on the chuck body, the clamping jaw is the rectangle, be equipped with vertical spout on the preceding terminal surface of clamping jaw, sliding connection has the slider in the spout, be fixed with the clamp splice on the slider, be fixed with the fixed plate of butt on the clamping jaw surface on the clamp splice, be equipped with the thread groove on fixed plate and the clamping jaw respectively, thread groove female connection has the fixing bolt who fixes the fixed plate on the clamping jaw.

Furthermore, the sliding groove and the sliding block are in a dovetail shape matched with each other.

The utility model has the advantages that:

like this when needs are changed, need not take off whole clamping jaw this moment, only need unscrew fixing bolt, make the slider by the roll-off in the spout, can take off like this the clamp splice that is located the clamping jaw front end change can to can also change the clamp splice of different shapes according to the type of work piece, neither need loaded down with trivial details change whole clamping jaw like this can also change the clamp splice of different grade type, made things convenient for the use.

Drawings

Fig. 1 is a schematic front view of the present invention;

fig. 2 is a right-side structural schematic view of the clamping jaw of the present invention;

in the figure: 1. a chuck body; 2. a clamping jaw; 3. a chute; 4. a slider; 5. a clamping block; 6. a fixing plate; 7. and (5) fixing the bolt.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.

As shown in the figure, the utility model discloses a chuck body 1 and the clamping jaw 2 of setting on chuck body 1, clamping jaw 2 is the rectangle, be equipped with vertical spout 3 on the preceding terminal surface of clamping jaw 2, sliding connection has slider 4 in the spout 3, be fixed with clamp splice 5 on the slider 4, be fixed with butt fixed plate 6 on clamping jaw 2 surface on clamp splice 5, be equipped with the thread groove on fixed plate 6 and the clamping jaw 2 respectively, thread groove female connection has fixes fixing bolt 7 on clamping jaw 2 with fixed plate 6. The sliding groove 3 and the sliding block 4 are in a dovetail shape matched with each other. Therefore, the sliding block 4 cannot slide out of the sliding groove 3, and the stability is improved.

The utility model has the advantages that:

like this when needs to be changed, need not take off whole clamping jaw 2 this moment, only need unscrew fixing bolt 7, make slider 4 by the roll-off in the spout 3, can take off like this and be located the clamp splice 5 of clamping jaw 2 front end and change can to can also change the clamp splice 5 of different shapes according to the type of work piece, neither need loaded down with trivial details change whole clamping jaw 2 like this can also change the clamp splice 5 of different grade type, made things convenient for the use.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.

Claims (2)

1. A hydraulic chuck, characterized by: including chuck body and the clamping jaw of setting on the chuck body, the clamping jaw is the rectangle, be equipped with vertical spout on the preceding terminal surface of clamping jaw, sliding connection has the slider in the spout, be fixed with the clamp splice on the slider, be fixed with the fixed plate of butt on the clamping jaw surface on the clamp splice, be equipped with the thread groove on fixed plate and the clamping jaw respectively, thread groove female connection has the fixing bolt who fixes the fixed plate on the clamping jaw.
