At present, to the processing of workpiece, at first need to be fixed in the industrial production, it is easy to operate, fixed that workpiece fixing both required, and requires can not injure the surface of workpiece again.Workpiece for regular shape generally all adopts general anchor clamps to fix processing, operate also more convenient, but for the special-shaped workpiece of some shapes and irregular structure, its certain difficulty that has been fixed up.Be made up of a plurality of difform parts because of it, the shape of outer surface is very irregular, adopts general anchor clamps can't fix at all.Also have, in Production of bearing, because the working method of supporting fixture is limit, also cause workpiece the quality problems of Zhi Chengyin and scuffing to occur easily in the particularly super Seiko preface.The special sectional fixture of many employings of past, method is by hand installed workpiece, owing to need with handspring hub cap plate and pilot pin, also to adjust part position with tweezers, unavoidably can pollute and the damage problem of product has also increased difficulty hand-manipulated, and efficient is not high yet.
Summary of the invention
In order to overcome the deficiency that prior art exists, the purpose of this utility model be to provide a kind of mechanism flexibly, the work piece holder of good positioning effect.
For reaching above purpose, the utility model provides a kind of work piece holder, comprise chuck body, be arranged on the fixed part on the described chuck body, be arranged on the control device that is used to control described fixed part clamping work pieces on the described chuck body or unclamps workpiece, described fixed part comprises first fixed cell that is used for fixing described workpiece screwed hole place, the 3rd fixed cell that is used for fixing second fixed cell of the described edge of work and is used for fixing described workpiece corner, described first fixed cell, second fixed cell and the 3rd fixed cell are around described workpiece.
Further improvement of the utility model is, described control device is cylinder and a plurality of tracheaes of being connected with described fixed part.
Further improvement of the utility model is that the quantity of described first fixed cell is two.
Further improvement of the utility model is that described first fixed cell comprises first connecting portion that first of U type compresses end and is hinged with described chuck body, and the bottom of described first connecting portion is connected with described control device.
Further improvement of the utility model is that described second fixed cell comprises two fixed mechanisms, and two described fixed mechanisms are separately positioned on the both ends of the described edge of work.
Further improvement of the utility model is that described second fixed mechanism comprises second compressed part of strip and second connecting portion that is hinged with described chuck body, and the bottom of described second connecting portion is connected with described control device.
Further improvement of the utility model is, described the 3rd fixed cell comprises the 3rd connecting portion that has outer peripheral the 3rd compressed part of arc and be hinged with described chuck body, and the bottom of described the 3rd connecting portion is connected with described control device.
The beneficial effects of the utility model are: owing to adopted above technical scheme, at first fixed part comprises first fixed cell that is used for fixing workpiece screwed hole place, the 3rd fixed cell of the workpiece corner that is used for fixing second fixed cell of the edge of work and is used for fixing, various difform zones have dissimilar fixed cells to fix, more pointed, secondly because three types fixed cell all has setting, so various difform products can use these anchor clamps to fix, make product have flexibility, multiple product can use same anchor clamps, reduce the production cost of anchor clamps, also reduced production cost of products.
Description of drawings
Accompanying drawing 1 is the structural representation of work piece holder duty in the present embodiment.
Wherein
1, chuck body; 2, first fixed cell; 3, second fixed cell; 4, the 3rd fixed cell; 5, workpiece.
The specific embodiment
Below preferred embodiment of the present utility model is described in detail, thereby protection domain of the present utility model is made more explicit defining so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that.
Referring to accompanying drawing 1, a kind of work piece holder, comprise chuck body 1, be arranged on fixed part on the chuck body 1, be arranged on and be used to the control device controlling fixed part clamping work pieces 5 or unclamp workpiece 5 on the chuck body 1, fixed part comprises first fixed cell 2 that is used for fixing workpiece 5 screwed hole places, be used for fixing second fixed cell 3 at workpiece 5 edges and the 3rd fixed cell 4, the first fixed cells 2, second fixed cell 3 and the 3rd fixed cell 4 of workpiece 5 corners that are used for fixing around workpiece 5.
Control device is cylinder and a plurality of tracheaes of being connected with fixed part, uses the solid component controls precision height of cylinder control, safety, quick.
The quantity of first fixed cell 2 is two.First fixed cell 2 comprises first connecting portion that first of U type compresses end and is hinged with chuck body 1, and the bottom of first connecting portion is connected with control device.First of U type compresses end when the collet threaded hole, and U type part can be avoided the position of screwed hole, does not influence the processing of screwed hole.
Second fixed cell 3 comprises two fixed mechanisms, and two fixed mechanisms are separately positioned on the both ends at workpiece 5 edges.Second fixed mechanism comprises second compressed part of strip and second connecting portion that is hinged with chuck body 1, and the bottom of second connecting portion is connected with control device.Workpiece 5 edges adopt two fixed mechanisms to compress respectively, have fixed the position at edge, and first compressed part of strip can well be fitted with microscler edge on the other hand, firmly evenly, compress effective.
