Abstract

The invention belongs to the technical field of machining equipment and discloses a self-resetting drilling fixture comprising a bottom plate, a positioning block, a clamping block and a driving device; the positioning block and the clamping block are disposed on the bottom plate face to face; the driving device drives the clamping block to slide to the positioning block; a reset spring is connected between the positioning block and the clamping block; opposing faces of the positioning block and the clamping block are provided with at least two V-grooves facing each other; the driving device comprises a cylinder and a wedge connected to a piston rod of the cylinder; a sliding direction of the wedge is perpendicular to that of the clamping block; the surface, corresponding to certain V-grooves, of the wedge is a slope matching with a slope of the wedge; rollers are arranged and supported on the slope of the clamping block; the slope of the wedge is tangent to the surfaces of the rollers. The self-resetting drilling fixture has the advantages that machining efficiency is improved, self-locking after clamping is available, self-resetting after completion is available, and a drilling process is more reliable and accurate.

Description

A kind of self-replaced type boring grab

Technical field

The present invention relates to machining device technical field, in particular to a kind of self-replaced type boring grab.

Background technology

At present, in the manufacture process of the parts such as swivel joint, disk like part end face hole machined adopts rig to machine usually, can not self-locking after the clamp on existing rig, and when power is larger, workpiece easily loosens, and be single clamping workpiece mostly, in batch machining, handling often, troublesome poeration, more than one piece clamping demand cannot be met, cause working (machining) efficiency low, and multiple clamping causes, and cumulative errors are large affect workpiece processing quality.

Summary of the invention

The object of the present invention is to provide a kind of efficiently, the self-replaced type boring grab of multi-work piece, to solve the problem.

For realizing the object of the invention, the technical scheme adopted is: a kind of self-replaced type boring grab, comprise clamp bottom board, be positioned on clamp bottom board and the drive unit that slides to locating piece direction of the locating piece be oppositely arranged and clamp, driving clamp, locating piece is fixedly installed; Back-moving spring is connected with between locating piece and clamp; The opposite face of locating piece and clamp offers mutually corresponding V-shaped groove, and the V-shaped groove on locating piece and clamp is at least two; The wedge that drive unit comprises cylinder and is connected with cylinder piston rod, the glide direction of wedge is vertical with the glide direction of clamp, and the surface relative with V-shaped groove of clamp is inclined-plane, and the slopes which match of described inclined-plane and wedge; On the inclined-plane of clamp, arrangement is supported with roller, and inclined-plane and the roller surface of wedge are tangent.

Further, the both sides of described clamp are provided with clamp gib block.

Further, the inclined-plane couple positioned opposite of described wedge has wedge gib block.

The invention has the beneficial effects as follows, not only meet the clamping and positioning requirement of multi-work piece, avoid and manually change workpiece frequently, reduce labour intensity, improve working (machining) efficiency, realize the more than one piece clamping ability of workpiece, and the driving of cylinder and wedge makes fixture by can self-locking after Workpiece clamping, workpiece activity phenomenon can not be there is, boring procedure is more accurately reliable, and carry out rolling friction by the roller of arrangement between wedge and clamp, avoid the sliding friction repeatedly in use procedure between inclined-plane and aggravate the wearing and tearing of clamp and wedge, clamp will be caused after wearing and tearing cannot to reach clamping formed and clamping failures, by back-moving spring, clamp is resetted after machining, ensure that the crudy of all workpiece, simple and practical.

Accompanying drawing explanation

Fig. 1 is the structural representation of self-replaced type boring grab provided by the invention.

Detailed description of the invention

Also by reference to the accompanying drawings the present invention is described in further detail below by specific embodiment.

Fig. 1 shows self-replaced type boring grab provided by the invention, comprise clamp bottom board 1, be positioned on clamp bottom board 1 and the locating piece 2 be oppositely arranged and clamp 3, the drive unit 4 that drives clamp 3 to slide to locating piece 2 direction, locating piece 2 is fixedly installed; Back-moving spring 6 is connected with between locating piece 2 and clamp 3; The opposite face of locating piece 2 and clamp 3 offers mutually corresponding V-shaped groove 5, and the V-shaped groove 5 on locating piece 2 and clamp 3 is at least two; The wedge 42 that drive unit 4 comprises cylinder 41 and is connected with cylinder piston rod, the glide direction of wedge 42 is vertical with the glide direction of clamp 3, and the surface relative with V-shaped groove 5 of clamp 3 is inclined-plane, and the slopes which match of inclined-plane and wedge 42; On the inclined-plane of clamp 3, arrangement is supported with roller 32, the inclined-plane of wedge 42 and roller 32 plane tangent.

The both sides of clamp 3 are provided with clamp gib block 31, and the inclined-plane couple positioned opposite of wedge 42 has wedge gib block 43, make the slip of clamp 3 and wedge 42 more smooth and easy, avoid crooked.Wedge 42 and clamp 3 are steelwork, and the angle on inclined-plane is 3 °-10 °, ensure good self-locking effect.

Add man-hour, multiple workpiece is placed on the V-shaped groove 5 of locating piece 2, by cylinder 41, wedge 42 is slided, and then by wedge inclined-plane and roller 32, clamp 3 is slided to locating piece 2 direction, by Workpiece clamping in the V-shaped groove 5 of locating piece 2 and clamp 3, realize clamping, back-moving spring 6 is compressed, after processing, wedge 42 is return, clamp 3 is automatically return under the active force of back-moving spring 6, can take out this batch of workpiece, convenient and swift.

The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
