Description
Technical field
The utility model relates to a kind of fixture, and be specifically is needing to add to multiple workpiece the Grip Compensating Means used man-hour simultaneously.
Background technology
As everyone knows, in field of machining, in order to increase work efficiency, a lot of occasion all needs to process multiple workpiece simultaneously, at this moment just needs to use clamping device, is clamped by these workpiece simultaneously, otherwise cannot realize the object of simultaneously processing.
Traditional clamping device all comprises frame (or platform), and frame is longitudinally disposed with slide and holder; The frame that described slide is corresponding has the line slide rail longitudinally arranged, have between slide and frame can promote this slide linearly slide rail slide actuating unit, slide has Work-sheet pressing cover; Described holder has through hole, and there is Workpiece fixing cover one end that through hole is adjacent with slide; Described through hole is identical with the quantity that Work-sheet pressing overlaps and be all no less than two, and the position one_to_one corresponding that the Workpiece fixing cover on through hole overlaps with Work-sheet pressing.During use, by workpiece one end alignment pieces positioning sleeve, then utilize actuating unit to promote slide and move to holder, make the Work-sheet pressing cover on slide prop up the other end of workpiece, the clamping of workpiece can be realized.A workpiece all clamped by Workpiece fixing cover, the Work-sheet pressing inner room of often organizing correspondence, both can reach the object that multi-work piece is processed simultaneously.But, because the processing dimension of workpiece exists error, make the distance between the clamping part of different workpieces inconsistent, therefore when using this clamping device to clamp multiple workpiece, usually can only by Workpiece clamping maximum for size, and other workpiece exists lax phenomenon, the precision of workpieces in subsequent processing can be affected like this.Particularly add man-hour to longer workpiece (as shaft-like, tubular workpiece etc.), this phenomenon is particularly evident.In order to solve the problem of the machining accuracy deficiency caused because piece-holder is not tight, just artificially manually must adjust the position of Work-sheet pressing cover on slide, part Work-sheet pressing is overlapped reduce with the distance of Workpiece fixing inner room, by Workpiece clamping, but this mode cannot realize the automation of equipment, and operating efficiency is low.
Utility model content
Problem to be solved in the utility model is to provide a kind of multi-work piece processing Grip Compensating Means, this device is adopted to clamp multiple workpiece, each workpiece can be made to be clamped completely, thus the precision of workpiece when following process can be guaranteed, the automation of equipment can be realized simultaneously, increase work efficiency.
For solving the problem, take following scheme:
Multi-work piece processing Grip Compensating Means of the present utility model comprises frame, and frame is longitudinally disposed with slide and holder.The frame that described slide is corresponding has the line slide rail longitudinally arranged, have between slide and frame can promote this slide linearly slide rail slide actuating unit, slide has Work-sheet pressing cover.Described holder has through hole, and there is Workpiece fixing cover one end that through hole is adjacent with slide.Described through hole is identical with the quantity that Work-sheet pressing overlaps and be all no less than two, and the position one_to_one corresponding that the Workpiece fixing cover on through hole overlaps with Work-sheet pressing.Be characterized in described Work-sheet pressing cover and slide between have compensation arrangement, this compensation arrangement comprises the first cylinder body being enclosed within Work-sheet pressing and putting, and two ends and the Work-sheet pressing inner room of this first cylinder body are that air-tight movable shape coordinates, the first cylinder body with between slide in being fixedly connected with.That section of Work-sheet pressing being positioned at the first cylinder body puts and is fixed with piston bush, coordinates between the periphery of piston bush with the inwall of the first cylinder body in air-tight movable shape.The first cylinder side wall that described piston bush two ends are corresponding all there is oilhole.
Further improvement of the utility model scheme is that one end of described first cylinder body has guide post, and the Work-sheet pressing that this guide post is corresponding has put pilot hole, and the guide post of the first cylinder body stretches in the pilot hole of Work-sheet pressing cover.The guiding mechanism adopting guide post and pilot hole to coordinate, can avoid Work-sheet pressing to overlap and rotate, the workpiece that it is clamped not easily torsional deformation.
Further improvement of the utility model scheme is fixed with swivel nut below described slide, has screw mandrel in this swivel nut, and the two ends of screw mandrel coordinate in rotatable shape with between frame.One end of described screw mandrel is connected with motor.Described actuating unit is formed by described swivel nut, screw mandrel and motor.Described swivel nut comprises the second cylinder body, has piston rod in the second cylinder body, and there is piston one end that piston rod is positioned at the second cylinder body, and the other end of piston rod stretches out from one end of the second cylinder body.The other end of the second cylinder body has guide rod, and the diameter of guide rod is greater than the other end, and in being sealedly and fixedly connected between one end that guide rod diameter is larger and the second cylinder body, one end that guide rod diameter is less is stretched in the second cylinder body.Described piston rod, piston, guide rod all have axial hole, and piston bush is on guide rod, and one end that piston rod is positioned at outside the second cylinder body is processed with internal thread, and described screw mandrel through the axial hole of piston rod, piston, guide rod, and matches with the internal thread of piston rod.The second cylinder side wall that described piston two ends are corresponding all there is oilhole.Adopt the fit system of screw mandrel and the second cylinder body, piston, piston rod, slide can be made steadily, smoothly to slide on line slide rail, while possess again the function of buffering, not easily cause the damage of holding workpiece.
Further improvement project of the present utility model is that the central aperture edge of described Work-sheet pressing cover and Workpiece fixing cover abutting end is all processed with inclined-plane.The location of workpiece can be conducive to like this, workpiece is not easily shifted in following process process.
Take such scheme, have the following advantages:
Work-sheet pressing due to multi-work piece processing Grip Compensating Means of the present utility model overlaps and has compensation arrangement between slide, this compensation arrangement comprises the first cylinder body being enclosed within Work-sheet pressing and putting, two ends and the Work-sheet pressing inner room of this first cylinder body are that air-tight movable shape coordinates, the first cylinder body with between slide in being fixedly connected with; That section of Work-sheet pressing being positioned at the first cylinder body puts and is fixed with piston bush, coordinates between the periphery of piston bush with the inwall of the first cylinder body in air-tight movable shape; The first cylinder side wall that described piston bush two ends are corresponding all there is oilhole.When using this device to clamp multiple workpiece, first utilize actuating unit to promote slide to move to holder, multiple workpiece is made to be clamped between Work-sheet pressing cover and Workpiece fixing cover, but now the actual workpiece only having size maximum is clamped completely, and other workpiece be in can the state of slight movement, then external fuel transfer system is utilized to the first cylinder body not corresponding to the workpiece that clamps completely away from oiling in that oilhole of workpiece, the oil injected in the first cylinder body will promote piston bush and Work-sheet pressing cover is mobile to Workpiece fixing cover, thus this workpiece is clamped completely.Therefore, use this device to clamp multiple workpiece simultaneously, can guarantee that all workpiece are clamped completely, like this, these workpiece, when following process, there will not be phenomenon that is lax or movement, can ensure machining accuracy.
