Abstract
The utility model relates to machining tool parts and provides a clamping disk which comprising a clamping claw, according to the plan view, the clamping claw is provided with two outward extension portions, and openings of the extension portions are oppositely arranged; fastening teeth are respectively arranged on inner sides of the extension portions, and working faces of the fastening teeth are in an arc-shaped structure, so that the clamping disk has the advantages that a barrel-shaped workpiece is clamped and not easy to deform, and the barrel-shaped workpiece is clamped tightly.
Description
Technical field
The utility model relates to machine tool component, specifically relates to a kind of chuck.
Background technology
Chuck has claw, in the prior art, from top view, claw all is the structure of " one " font, because chuck often has three or four claws, such chuck also can clamping workpiece, but for some than the workpiece that is easier to be out of shape, for example cylindrical work pieces uses such claw just inconvenient.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned shortcoming, and a kind of cylindrical work pieces chuck not yielding, that block tightly again that tightens is provided.
The technical solution of the utility model is achieved in that a kind of chuck, comprises claw, it is characterized in that: from top view, described claw has two outside again extensions of relative opening, and the inboard of extension respectively is provided with steps up tooth.
Say that further the described working face that steps up tooth is circular-arc structure.
The beneficial effects of the utility model are: such chuck has chucking cylindrical work pieces advantage not yielding, that block tightly again.
Description of drawings
Fig. 1 is the structural representation of claw of the present utility model.
Wherein: 1, extension 2, step up tooth.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of chuck comprises claw, it is characterized in that: from top view, described claw has two outside again extensions 1 of relative opening, and the inboard of extension 1 respectively is provided with steps up tooth 2.
Say that further the described working face that steps up tooth 2 is circular-arc structure.
Claims (2)
1. a chuck comprises claw, it is characterized in that: described claw has two outside again extensions of relative opening, and the inboard of extension respectively is provided with steps up tooth.
2. chuck according to claim 1, it is characterized in that: the described working face that steps up tooth is circular-arc structure.
