Abstract
The utility model discloses a kind of self-locking boring grab, belong to machining device technical field, 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; 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 described inclined-plane mates laminating mutually with the inclined-plane of wedge.Avoid and manually change workpiece frequently, improve working (machining) efficiency, can self-locking after clamping, boring procedure is more accurately reliable.
Description
Technical field
The utility model relates to machining device technical field, in particular to a kind of self-locking 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.
Utility model content
The purpose of this utility model be to provide a kind of efficiently, the self-locking boring grab of multi-work piece, to solve the problem.
For realizing the utility model object, the technical scheme adopted is: a kind of self-locking 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; 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 described inclined-plane mates laminating mutually with the inclined-plane of wedge.
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 beneficial effects of the utility model are, 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, and workpiece activity phenomenon can not occur, boring procedure is more accurately reliable, ensure the crudy of all workpiece, simple and practical.
Accompanying drawing explanation
Fig. 1 is the structural representation of the self-locking boring grab that the utility model provides.
Detailed description of the invention
Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.
Fig. 1 shows the self-locking boring grab that the utility model provides, 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; 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, the surface relative with V-shaped groove 5 of clamp 3 is inclined-plane, and inclined-plane mates laminating mutually with the inclined-plane of wedge 42.
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 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 by wedge inclined-plane, realize clamping, after processing, wedge 42 is return, then is return by clamp 3 by artificial or frame for movement, this batch of workpiece can be taken out, convenient and swift.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
