Abstract

The invention discloses a workpiece clamping base. The workpiece clamping base comprises a main body, wherein a clamping groove is formed in the main body; and two or more slits penetrating through the clamping groove are formed in the inner side wall of the clamping groove. The workpiece clamping base can accommodate and clamp all workpieces with different sizes in a workpiece tolerance range, tightly clamps the workpieces inside, and is excellent in clamping effect.

Description

The grip slipper of a kind of workpiece

Technical field

The present invention relates to a kind of grip slipper for holding workpiece.

Background technology

Usually, workpiece to be processed, before processing, all needs to grip so that it is position is fixed. It is carried out clamping operation, on the one hand, is to make workpiece obtain relative to the correct position of lathe and cutter; On the other hand, also it is ensure that it is in the course of processing, because of processing by power, shift in position can not occur, cause processing work because of shift in position, and be subject to the process operation that should not have, so that processing work is scrapped.

Further, the Workpiece clamping mode that industry is conventional, it is possible to be directly by Workpiece clamping on operating machine platform, or clamped by the special fixture that clamps.

Refer to shown in Fig. 3,4, which illustrates the clamping device of a kind of workpiece. Wherein said clamping device comprises a body 30, is provided with accepting groove 32 in it, for collecting also holding workpiece. This kind of work holder, has structure simple, it is easy to the advantage of operation. But this kind of clamping device, also has a shortcoming, it is exactly that its accuracy requirement is higher.

But, owing to work pieces process all has certain tolerance zone, sometimes the size of workpiece can in the upper limit of its tolerance of dimension, sometimes at lower limit, sometimes moderate. Therefore, finally completing the workpiece of processing, its size is larger sometimes, sometimes again can be smaller. This is for workpiece itself, owing to, all in dimensional tolerance range, therefore, being all qualified. But this is for clamping device, owing to the size of its accepting groove 32 is fixing, this kind of dimensional change, can have a significant impact it.

Such as, if the collecting size of accepting groove, it is the intermediate sizes being in holding workpiece dimensional tolerance range. So, if the tolerance dimension of holding workpiece is more moderate, will well be housed in accepting groove; And if the tolerance dimension of holding workpiece is less than normal, just there will be collecting gap; And if the tolerance dimension of holding workpiece is bigger than normal, then likely accommodates very tight, even can not accommodate in it.

Therefore, necessary develop a kind of novel piece-holder seat, overcome defect of the prior art.

Summary of the invention

It is an object of the invention to provide the grip slipper of a kind of workpiece, in it, piece-holder is fastening, good clamping effect.

In order to realize above-mentioned purpose, the technical solution used in the present invention is as follows:

A grip slipper for workpiece, it comprises main body, is provided with clip slot in wherein said main body, and described clip slot inner side-wall is provided with cracking of 2 or more quantity.

Further, wherein said clip slot comprises cylindrical configuration.

Further, wherein said clip slot comprises spline. Can be used for accommodating the workpiece of spline configuration in it.

Further, the wherein said setting that is symmetrically distributed of cracking.

Further, the wherein said quantity cracked is 3, and becomes triangular symmetrical to distribute.

Further, the wherein said quantity cracked is 4, and is symmetrically distributed.

Further, the wherein said width cracked is at 0.5 ~ 2mm.

Further, the wherein said width cracked is at 0.5 ~ 1.5mm.

Relative to prior art, the present invention has following useful effect: the grip slipper of a kind of workpiece that the present invention relates to, it by arranging many symmetrical slotting structures on its clip slot inwall, make the workpiece of its applicable different size in tolerance zone, there will not be have workpiece because of tolerance dimension slightly big, and the problem that can not clamp; Or workpiece because of tolerance dimension slightly little, and occur clamp gap problem.

Embodiment

Below with reference to Figure of description, the technical scheme of the grip slipper of a kind of workpiece that the present invention relates to is described in further detail.

Referring to shown in Fig. 1,2, an embodiment of the invention, it provides the grip slipper of a kind of workpiece, it comprises jig main body 10.

On wherein said jig main body 10, it is provided with in it for accommodating and the clip slot 12 of holding workpiece. Wherein said clip slot 12, its groove body can be specifically cylinder configuration, or other are corresponding to the configuration of holding workpiece retaining part. Such as, if the retaining part of workpiece is spline structure, the inside configuration of its clip slot can be then spline cover configuration.

Further, on the inner side-wall of described clip slot 12, also it is provided with 4 and symmetrical cracks 14. Due to the gap that slotting structure exists, so that the collecting size of described clip slot can have certain range. Wherein said slotting structure, in one embodiment, its width can be about about 1mm, but is not limited to. Concrete width dimensions, according to actual needs, can have certain change. The slotting structure of width like this is set, contributes to more accurate, firm holding workpiece; Meanwhile, also there is the consideration of the processing aspect of structure own and structural strength aspect.

Specifically, described clip slot 12, it is in the process of collecting workpiece, when running into the slightly big situation of the workpiece size of collecting, described clip slot inwall can be produced extruding by described collecting workpiece, it is forced to produce certain elasticity distortion, and at this moment, due to described clip slot sidewall, it is provided with slotting structure, because described slotting structure Existential Space gap, thus can absorb certain extruding distortion that described clip slot sidewall produces, thus workpiece can be accommodated smoothly. So, can not occur again workpiece because of tolerance dimension bigger time, situation about can not be accommodated by described clip slot. Simultaneously, it is also possible to because, in this kind of collecting process, a certain amount of extruding produced is out of shape so that described workpiece, it is possible to firm is housed in described clip slot.

Such as, in an embodiment, the grip slipper of this kind of workpiece that the utility model relates to, the initial collecting size (comprising slotting structure) of its clip slot, it can be designed as the minimal tolerance scope size of corresponding holding workpiece, so that can accommodate holding workpiece more closely.

The foregoing is only one embodiment of the present of invention, it is not limited to this invention. All in the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
