Abstract
The utility model relates to a novel chuck jaw, which comprises a jaw and a through hole, wherein the jaw is connected with a chuck; the through hole is formed in a jaw connecting seat; and a sliding chute is formed at the back of the jaw connecting seat. The novel chuck jaw is characterized in that a sectorial clamping part which can increase the contact area with a workpiece and clamp the workpiece tightly is connected to the lower part of the jaw connecting seat. The novel chuck jaw provided by the utility model can increase the contact area with the workpiece.
Description
[technical field]
The utility model relates to a kind of chuck technical field, especially relates to the claw in the chuck.
[background technology]
In the prior art, generally dispose scroll chuck on lathes such as lathe, milling machine, drilling machine, have claw on the chuck, claw can be regulated distance each other so that cylindrical work is clamped in the appropriate location.The claw that uses mostly is a claw Connection Block, has the hole that is used for fixing in the claw Connection Block at present, claw Connection Block bottom is provided with the application point that is used for fixing workpiece, the contact-making surface of this claw and workpiece is less, might cause wearing and tearing or distortion to the surface of workpiece when clamping.
[utility model content]
The utility model has overcome the deficiencies in the prior art, and a kind of claw that can increase with the workpiece contact-making surface is provided.
For addressing the above problem, the utility model by the following technical solutions:
A kind of novel chuck jaws, comprise the claw Connection Block that is connected with chuck and be arranged on through hole in the claw Connection Block, be provided with chute at claw Connection Block back, but it is characterized in that below the claw Connection Block, being connected with the fan-shaped clamping part that can increase with workpiece contact area and clamping work pieces.
Aforesaid a kind of novel chuck jaws is characterized in that the width of the width on the arc limit, bottom surface that described fan-shaped clamping part contacts with workpiece greater than the claw Connection Block, and the thickness on the arc limit, bottom surface of described fan-shaped clamping part is greater than the thickness of claw Connection Block.
Aforesaid a kind of novel chuck jaws is characterized in that described fan-shaped clamping part and claw Connection Block are integrally formed, and described through hole is a shoulder hole.
The utility model compared with prior art has following advantage:
The utility model adopts and to comprise the claw Connection Block that is connected with chuck and to be arranged on through hole in the claw Connection Block, be provided with chute at claw Connection Block back, but below the claw Connection Block, be connected with the scheme that can increase with the fan-shaped clamping part of workpiece contact area and clamping work pieces, a kind of contact-making surface that increases workpiece and claw when processing work is provided, has avoided surface of the work is caused the claw of wearing and tearing or distortion.
[description of drawings]
Fig. 1 is the utility model vertical view.
Fig. 2 is that the utility model A-A is to cutaway view.
Fig. 3 is that the utility model B-B is to cutaway view.
[specific embodiment]
A kind of novel chuck jaws, comprise the claw Connection Block 1 that is connected with chuck and be arranged on through hole 2 in the claw Connection Block 1, be provided with chute 11 at claw Connection Block 1 back, but below claw Connection Block 1, be connected with the fan-shaped clamping part 3 that can increase with workpiece contact area and clamping work pieces.
Specifically, the width B on the arc limit, bottom surface that described fan-shaped clamping part 3 contacts with workpiece is greater than the width L of claw Connection Block 1, the thickness D on the arc limit, bottom surface of described fan-shaped clamping part 3 is greater than the thickness H of claw Connection Block 1, increase the contact area of fan-shaped clamping part 3 and workpiece so widely, avoided the surface of the work wearing and tearing or the distortion that cause because of contact-making surface is too small.
Described fan-shaped clamping part 3 is integrally formed with claw Connection Block 1, and the through hole 2 that is arranged in the claw Connection Block 1 is shoulder hole.After the chute 11 at claw Connection Block 1 back slides on the chuck, by through hole 2 claw Connection Block 1 is fixed on the chuck with bolt.
Claims (3)
1. novel chuck jaws, comprise the claw Connection Block (1) that is connected with chuck and be arranged on the interior through hole (2) of claw Connection Block (1), be provided with chute (11) at claw Connection Block (1) back, it is characterized in that at claw Connection Block (1) but the below is connected with and can increases and the workpiece contact area fan-shaped clamping part (3) of clamping work pieces also.
2. a kind of novel chuck jaws according to claim 1, it is characterized in that the width (L) of the width (B) on the arc limit, bottom surface that described fan-shaped clamping part (3) contacts with workpiece greater than claw Connection Block (1), the thickness (D) on the arc limit, bottom surface of described fan-shaped clamping part (3) is greater than the thickness (H) of claw Connection Block (1).
