Abstract

The utility model relates to a water shape universal chuck for a machine tool, which belongs to the technical field of fastener, and comprises a chuck body, jaws, scrolls, a conical gear, positioning screws, a pressing cover, sliding gripping jaws, sliding jaws, a clamping ring and regulating screws. The utility model can complete the processing for the end face of a work piece with a T-shaped shell and an inner hole once in an installing and clamping mode, the requirement of the verticality of the end face of the work piece with a T-shaped shelll and the inner hole can not be effected because of installing and clamping in second time; so the labor efficiency can be enhanced, and the productive requirement can be satisfied.

Description

Water shape universal chuck for machine tool

The utility model belongs to technical field of fastening.

In machining, need fixedly workpiece of a kind of clamping device, employed three-jaw self-centering chuck in the present enterprise, be to drive parcel by the bevel gear on the rotating disk body to rotate, claw on the disk body is moved around, thereby reach the purpose that clamps or unclamp workpiece, this three-jaw self-centering chuck is when the end face of processing T shape housing workpiece and endoporus, need the secondary clamping just can process, thereby can not guarantee the vertical precision requirement of workpiece end face and endoporus, efficiency is low, can not meet the needs of production.

The purpose of this utility model provides a kind of clamping device, with this clamping device can No. one time clamping finish the processing of T shape housing workpiece end face and endoporus.

The utility model comprises disk body, the disk body front end face is that the center is provided with uniform " worker " font groove with the axis, claw is housed in the odd bin, uniform bevel gear passes outer garden and is sleeved on the engagement of the parcel on the garden disk body the rear end in and is inserted on the interior garden, the dog screw that contacts with the top of bevel gear is housed in the garden outside, the uniform screw that connects main shaft is arranged on the end face of outer garden, in disk body front end face " worker " the font even bin, one of them even bin is equipped with sliding jaw, remaining even bin is equipped with the slip claw, sliding jaw and slip claw are serially connected by tight ring, and the adjustment screw that is screwed on the tight ring is embedded in the T type groove of sliding jaw.

Because the utility model is to have increased sliding jaw and slip claw on the basis of former three-jaw self-centering chuck, all functions that promptly kept three-jaw self-centering chuck, can finish the clamping of T shape housing workpiece again by sliding jaw and slip claw, processing end face and endoporus are finished in a clamping, guaranteed the vertical precision requirement of workpiece end face and endoporus, improve efficiency, satisfied the needs of producing.

Describe concrete structure of the present utility model and use in detail below in conjunction with drawings and Examples.

Accompanying drawing has shown embodiment of the present utility model, wherein:

Fig. 1 is the front view of embodiment;

Fig. 2 is that Fig. 1 is along the cutaway view of B-B line and the revolved sectional view of C-C line;

Fig. 3 is the profile of Fig. 2 along the A-A line;

Fig. 4 is the side view of slip claw among the embodiment;

Fig. 5 is the front view of embodiment disk body;

Fig. 6 is the profile of Fig. 5 along D-D line " worker " font groove.

In the structure chart that provides, disk body (1) front end face is that the center is provided with uniform " worker " font groove with the axis, wherein in three odd bin (7) claw (9) is housed, uniform bevel gear (6) passes outer garden (19) and meshes and be inserted on the interior garden (3) with the parcel (5) that is sleeved on disk body (1) the rear end Nei Yuan (3), the dog screw (27) that contacts with the top of bevel gear (6) is housed in garden (19) outside, the uniform screw (18) that connects main shaft is arranged on outer garden (19) end face (21), outer face, interior garden (3) (20) tightens intrinsic gland (16), by screw (17) gland (16) is fastened on the outer face, interior garden (3) (20), in disk body (1) front end face " worker " the font even bin (4), one of them even bin (4) is equipped with sliding jaw (10), all the other two even bin (4) are equipped with slip claw (11), sliding jaw (10) end face (26) tightens intrinsic baffle plate (12), baffle plate (12) is fastened on sliding jaw (10) end face (26) by two screws (13) side by side, the opening end of slip claw (11) is fastened with pressing plate (24), pressing plate (24) is fastened on the opening end of slip claw (11) by screw (13), sliding jaw (10) and slip claw (11) are serially connected by tight ring (14), tight ring (14) interior garden face is provided with uniform concave plane (8), wherein have the center of a concave plane (8) to be provided with the screw (25) of the adjustment screw that spins (15), the adjustment screw (15) that is screwed on the tight ring (14) is embedded in the T-slot (23) of sliding jaw (10).

In use, turn-knob bevel gear (6), driving claw (9) clamps T shape housing (22) one end lateral surfaces, and then turn-knob adjustment screw (15) drives tight ring (14), drive slip claw (11) by tight ring (14), cambered surface (2) on the slip claw (11) is contacted with the tight concave plane of encircling on (14) interior garden (8), the other end of the auxiliary clamping and positioning T shape housing (22) of sliding jaw (10) and slip claw (11) makes T shape housing (22) not change position, former location.
