Although the clamp provides a plurality of stations, the support seat is provided with a groove which is preferably V-shaped, and the clamping surface is easily scratched.

SUMMERY OF THE UTILITY MODEL

In order to solve the not enough of prior art, the utility model provides a multistation axle class precision finishing anchor clamps, including clamp plate, locating plate, balancing piece, rotatory briquetting, press from both sides the cover, rotatory briquetting lock is on the balancing piece, the balancing piece is fixed on the clamp plate, it fixes on the locating plate to press from both sides the cover, the clamp plate centre gripping is in the position of keeping silent, the locating plate centre gripping is in the position of keeping silent, it includes tongue more than 2 at least to press from both sides the cover, be provided with the shaft hole on the tongue, the shaft hole passes through T shape seam intercommunication, works as during clamp plate relative positioning board axial motion, rotatory briquetting extrudees the tongue.

Further, the transverse edge of the T-shaped seam is communicated with the adjacent shaft holes, and the vertical edge of the T-shaped seam faces the rotary pressing block.

Further, one end of the rotating pressing block facing the tongue portion is provided with a V-shaped bulge.

Further, the protrusion is arc-shaped.

Further, when the rotating pressing block contacts the tongue, the vertical edge of the T-shaped slot faces the convex V-shaped opening.

The utility model has the advantages that the round hole is adopted for direct positioning, the positioning precision is high, and the clamping surface is not easy to scratch; a plurality of stations are provided, and the processing efficiency is improved; the clamping part can be replaced, the shaft machining of different diameters is adapted, and the application range is wide.

FIG. 1 is a perspective view of the overall structure of the present invention;

Detailed Description

In order to facilitate understanding for those skilled in the art, the present invention will be further described with reference to the accompanying drawings.

Referring specifically to fig. 1, the present invention comprises a pressing plate 18, a positioning plate 22, a balance block 16, a rotating pressing block 34, and a clamping sleeve 26. The pressing plate 18 is square, a rectangular groove 32 is formed in one end of the pressing plate, the balance block 16 is square, an arc opening 30 is formed in one end of the balance block, the rotating pressing block 34 is provided with an outer contour 38 matched with the arc opening 30, the rotating pressing block 34 is buckled on the balance block 16 and is arranged in the rectangular groove 32 together, and the screw 42 is inserted from the top of the pressing plate 18 and screwed into a corresponding screw hole in the balance block 16 to connect the pressing plate with the balance block. One end of the collet 26 is inserted into the slot 40 of the positioning plate 22 and fastened to the positioning plate 22 by a screw 46. The pressing plate 18 is fixed on the movable jaw position, the positioning plate 22 is fixed on the stationary jaw position, the pressing plate 18 moves axially towards the positioning plate 22 under the action of external force, and the pressing block 34 is rotated to extrude the tongue part until the shaft part is clamped.

In order to improve the processing efficiency, the jacket 26 at least comprises 2 tongues 12, the shaft holes 20 are arranged on the tongues 12, a slit 36 is arranged between the shaft holes 20 on the same tongue 12, the slit 36 is T-shaped, the transverse edge of the slit is communicated with the shaft holes 20, and the vertical edge of the slit faces the rotating pressing block 34. The slots 36 divide the tongue 12 into pieces with some clearance between the pieces. The collet 26 is not limited to being made of brass, aluminum bronze, aluminum, 65Mn, or other elastic material, and thus the tongue 12 has a certain toughness and is easily deformed and contracted.

One end of the rotary pressing block 34 facing the tongue portion 12 is provided with a V-shaped protrusion 28, when the pressing plate 18 moves axially relative to the positioning plate 22, the protrusion 28 abuts against the front end of the tongue portion 12, at this time, the vertical edge of the T-shaped slot just faces the V-shaped opening of the protrusion 28, and the protrusion 28 presses the tongue portion 12 to deform towards the vertical edge of the T-shaped slot, so that the shaft hole 20 contracts, and thereby the shaft-like parts are clamped. In order to make the force acting on the tongue 12 uniform, the projection 28 is preferably rounded.

In order to ensure sufficient hardness, the pressing plate 18, the positioning plate 22, the weight 16 and the rotating weight 34 are preferably made of Cr12, and heat treated with HRC 55-60.

The invention has been described with reference to the preferred embodiments, to the above examples which are not intended to limit the invention, and from reading the present description, those skilled in the art will be able to conceive of numerous modifications and variations to this structure, without departing from the inventive concept, any obvious alternative falling within the scope of the invention.
