Abstract

The utility model discloses a chuck three-jaw device which is used for clamping products. The chuck three-jaw device comprises a chuck and three clamping jaws, the three clamping jaws are respectively and perpendicularly connected to the chuck and evenly distributed on the circumference with the center of the chuck as the circle center, a lengthening part is arranged on each clamping jaw, a locating step is inwards perpendicularly arranged on the end face, close to the center of the chuck, of each lengthening part, and the end face, perpendicular to each lengthening part, of each locating step is a locating standard face for locating products. The chuck three-jaw device is simple in structure and convenient to manufacture and use; the long products can be naturally clamped.

Description

A kind of chuck three-jaw
Technical field
The utility model relates to a kind of chuck three-jaw.
Background technology
At present, lathe generally adopts chuck three-jaw to carry out clamping product, and chuck three-jaw comprises chuck and three claws, and three claws are vertically connected at respectively chuck and are uniformly distributed in take on the circumference that chuck hub is the center of circle.There is certain defect in this structure: the length of claw only has 40mm, cannot the longer product of clamping length; The end face that claw is clamped product is profile of tooth plane, easily product surface is caused and crushed, and the axiality of product is poor.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of chuck three-jaw, simple in structure, makes easy to usely, can very naturally clamp longer product.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A chuck three-jaw, for clamping product, described chuck three-jaw comprises chuck and three claws, described three claws are vertically connected at respectively chuck and are uniformly distributed in take on the circumference that chuck hub is the center of circle,
On described each claw, be respectively equipped with lengthening part, the end face near chuck hub on described each lengthening part is inwardly vertically provided with positioning step, and the end face perpendicular to lengthening part on described positioning step is the positioning reference plane for positioning product.
Further, on each lengthening part described in the utility model, near the end face of chuck hub, offer the arc surface of the indent matching with circle product external.
Further, each lengthening part described in the utility model is welded in corresponding claw.
Preferably, the length of each lengthening part described in the utility model is 50 ~ 90mm.
Therefore compared with prior art, the utility model has following beneficial effect:
Lengthening part has increased the length of claw, and can pass through the accurate positioning product of positioning reference plane, therefore can very naturally clamp longer product, and simple in structure, makes easy to use.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present utility model, forms the application's a part, does not form to improper restriction of the present utility model, in the accompanying drawings:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 be in Fig. 1 AA to cutaway view.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, describe the utility model in detail, in this illustrative examples of the present utility model and explanation, be used for explaining the utility model, but not as to restriction of the present utility model.
Be the embodiment of a kind of chuck three-jaw described in the utility model as depicted in figs. 1 and 2, for clamping product, the present embodiment comprises chuck 5 and three claws 4, three claws 4 are vertically connected at respectively chuck 5 and are uniformly distributed in take on the circumference that chuck 5 centers are the center of circle, on each claw 4, be respectively equipped with lengthening part 7, end face near chuck 5 centers on each lengthening part 7 is inwardly vertically provided with positioning step 3, and the end face perpendicular to lengthening part 7 on positioning step 3 is the positioning reference plane 31 for positioning product.
Further, in the present embodiment, on each lengthening part 7, near the end face at chuck 5 centers, offer the arc surface 6 of the indent matching with circle product external.When arc surface 6 can guarantee product clamping, can not crushed, and the axiality of product is higher.
Further, in the present embodiment, each lengthening part 7 is welded in corresponding claw 4, connects so more firm.
Preferably, in the present embodiment, the length of each lengthening part 7 is 50 ~ 90mm, can guarantee to clamp the product of all lengths.
It is as follows that the utility model is made use procedure:
1, by original three-jaw 4 with lengthening part 7 at welding 1 place, welding 2 places weld respectively;
2, welding portion is processed smooth;
3, on lengthening part 7, the end face near chuck 5 centers processes positioning step and positioning table terrace 31;
4, on lengthening part 7, the end face near chuck 5 centers is made as arc surface 6;
5, by three-jaw 4 clampings on chuck 5;
6, product is put into chuck 5, near positioning table terrace 31, by spanner lock portion 8 locking products.
The technical scheme above the utility model embodiment being provided is described in detail, applied specific case herein the principle of the utility model embodiment and embodiment are set forth, the explanation of above embodiment is only applicable to help to understand the principle of the utility model embodiment; , for one of ordinary skill in the art, according to the utility model embodiment, in the specific embodiment and range of application, all will change, in sum, this description should not be construed as restriction of the present utility model meanwhile.
