Compared with the prior art, the pyramidal face fixture has the advantages of compact structure, smaller weight, small eccentricity of gravity center, good equilibrium, and convenient installation of claws, accurate location and high processing effect, and is applicable to the process of the workpiece with a processed position which forms an angle of 90 degrees with a locating surface.

Description

Pedestal car conical surface anchor clamps

Technical field

The utility model belongs to the Machining Technology field, is specifically related to a kind of pedestal car conical surface anchor clamps.

Background technology

The processing of traditional lathe is many to be fixedly clamped by chuck, wherein when being 90 °, product working position and locating surface use machined into, generally be to adopt the bended plate type clamp structure, need manually compress, its bended plate type clamp structure is relatively heavier, needs the check and correction balance, but because the anchor clamps own wt is heavier, rotating speed is lower during machined into, the low and acceleration equipment main shaft serious wear of working (machining) efficiency.

The utility model content

For solving the above-mentioned defective that prior art exists, the purpose of this utility model is to provide a kind of compact conformation, and balance is good, convenient mounting and clamping, the pedestal car conical surface anchor clamps that working (machining) efficiency is high.

For achieving the above object, the technical solution adopted in the utility model is: these pedestal car conical surface anchor clamps have chuck body, chuck body is provided with four clamp jaws, it is characterized in that: described four clamp jaws have a fixed claw, fixed claw is provided with location-plate, the clamp jaw of fixed claw both sides is the elasticity jaw, the elasticity jaw is fixed on the elasticity jaw bearing, elasticity jaw bearing is arranged on the chuck body, described fixed claw opposite side is provided with the paw that is used for workpiece pressing, paw is fixed on the paw bearing, and the paw bearing is arranged on the chuck body.

Adopt the beneficial effect of technique scheme: these pedestal car conical surface anchor clamps, has chuck body, chuck body is provided with movably elasticity jaw and one paw movably of a fixed claw, two, paw is fixed on the paw bearing, fixed claw is provided with location-plate, can be in radial location, two elasticity jaws clamp for auxiliary, increase rigidity, chuck moves under the lathe dynamic action, paw bearing radial action drives paw and moves to chuck hub, and the profile that the compressed part of paw is positioned at workpiece adapts, thus workpiece pressing.Compared with prior art, whole pedestal car conical surface clamp structure compactness, weight is lighter, and center of gravity is eccentric little; balance is good, convenient mounting and clamping, and accurate positioning, the lathe rotating ratio improved more than 1 times originally; the working (machining) efficiency height has reduced the wearing and tearing of acceleration equipment main shaft, can protect equipment effectively.Be fit to the machined into that working position and locating surface are 90 ° workpiece.

Description of drawings

Below in conjunction with accompanying drawing specific embodiment of the utility model is described in further detail.

Fig. 1 is the structural representation of the utility model pedestal car conical surface anchor clamps.

Fig. 2 is the left view of Fig. 1.

The specific embodiment

As Fig. 1, pedestal car conical surface anchor clamps shown in 2, has chuck body 6, chuck body 6 is installed on the main shaft of lathe, chuck body 6 is provided with four clamp jaws, a fixed claw is wherein arranged, fixed claw is a location bearing 4, positioning support 4 is provided with location-plate 3, the clamp jaw of fixed claw both sides is an elasticity jaw 7,8, elasticity jaw 7,8 are fixed on elasticity jaw bearing 9, on 10, elasticity jaw bearing 9,10 are arranged on the chuck body 6, the fixed claw opposite side is provided with the paw 2 that is used for workpiece pressing 5, the profile that the compressed part of paw 2 is positioned at workpiece adapts, and paw 2 is fixed on the paw bearing 1, and paw bearing 1 is arranged on the chuck body 6.When clamping workpiece, workpiece is placed in these anchor clamps, and by location-plate 3 location, paw 2 and elasticity jaw 7,8 clamp workpiece under the lathe dynamic action, reality carry out clamping and positioning the time.

Claims (1)

1, a kind of pedestal car conical surface anchor clamps, has chuck body, chuck body is provided with four clamp jaws, it is characterized in that: described four clamp jaws have a fixed claw, and fixed claw is provided with location-plate, the clamp jaw of fixed claw both sides is the elasticity jaw, the elasticity jaw is fixed on the elasticity jaw bearing, and elasticity jaw bearing is arranged on the chuck body, and described fixed claw opposite side is provided with the paw that is used for workpiece pressing, paw is fixed on the paw bearing, and the paw bearing is arranged on the chuck body.
