Description
Technical field
The utility model relates to a kind of Digit Control Machine Tool relevant device, specifically a kind of expansion type numerical control machine tool clamp.
Background technology
Digit Control Machine Tool often has part to need two ends turning when processing parts, or on same section and trapezoidal faces, also to carry out repeatedly concentrically ringed turning, its common point all will have higher axiality requirement when being exactly turning, fixture when traditional turnery processing generally adopts the mode of three-point fix to be clipped on part shell and is fixed part, because fixture is to effects such as the obstructions of the cutter of Digit Control Machine Tool, cutter moves freely at periphery of part, therefore can not process part inner side end, the mode of distribution processing must be adopted, and it is fixing to part implementation to adopt the mode of three-point fix to be clamped on part shell, part also can due to vibrations, the reason displacements such as fixture loosens, thus no matter be to the turning of part two ends or the concentric circles turning in same end face both sides, all considerable influence is produced to the coaxial accuracy of part processing, affect the machining accuracy of part, even part rejection, in order to the existing a kind of jig that solves the problem, but this fixture often can damage work piece surface when accommodating workpiece, and then have impact on the quality of workpiece.
Utility model content
The purpose of this utility model is to provide a kind of expansion type numerical control machine tool clamp, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of expansion type numerical control machine tool clamp, comprise pad, expand head, contiguous block, screw rod, overcoat, handle and sleeve, screw rod is provided with in described overcoat, screw rod right-hand member is provided with handle, screw rod left end connects expansion head, described overcoat left end is provided with contiguous block, and contiguous block left end is provided with sleeve, is provided with pad outside sleeve.
As further program of the utility model: be provided with screwed hole in described overcoat.
As further program of the utility model: described sleeve left side is provided with bellmouth.
As further program of the utility model: the material of described pad is elastomeric material.
As further program of the utility model: be evenly also provided with expansion groove outside described sleeve.
Compared with prior art, the beneficial effects of the utility model are: the utility model passes through rotary handle, expansion head then can pull to the right by screw rod, sleeve is under the expansionary force expanding head, workpiece is fixed, can not loosen, also can not because of clamping loose shift, fixation, cutter can in outer workpiece freely-movable, thus realize one-time positioning and can process at the multiple end face of part, thus when ensure that work pieces process, there is higher axiality, guarantee work pieces process quality, pad is provided with in addition outside described sleeve, the material of pad is elastomeric material, the effect of pad be convenient to anti-locking apparatus add clamping of workpieces time cause clamping face impaired problem, and then improve the crudy of device, and handle also to make staff exert a force more convenient, apparatus structure is simple, rationally, easy to operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of expansion type numerical control machine tool clamp, comprise pad 1, expand 2, contiguous block 3, screw rod 4, overcoat 5, handle 6 and sleeve 7, screwed hole is provided with in described overcoat 5, screw rod 4 is provided with in overcoat 5, screw rod 4 right-hand member is provided with handle 6, screw rod 4 left end connects and expands 2, described overcoat 5 left end is provided with contiguous block 3, contiguous block 3 left end is provided with sleeve 7, sleeve 1 left side is provided with bellmouth, pad 1 is provided with outside described sleeve 7, the material of pad 1 is elastomeric material, the effect of pad 1 be convenient to anti-locking apparatus add clamping of workpieces 8 time cause clamping face impaired problem, and then improve the crudy of device, evenly expansion groove is also provided with outside described sleeve 7, when needs holding workpiece 8, by rotary handle 6, expansion 2 can pull to the right by screw rod 4, sleeve 7 is expanding under the expansionary force of 2, workpiece 8 is fixed, can not loosen, also can not because of clamping loose shift, fixation, cutter can move at workpiece 8 external freedom, thus realize one-time positioning and can process at the multiple end face of part, thus ensure that workpiece 8 adds and has higher axiality man-hour, guarantee work pieces process quality, pad 1 is provided with in addition outside described sleeve 7, the material of pad 1 is elastomeric material, the effect of pad 1 be convenient to anti-locking apparatus add clamping of workpieces 8 time cause clamping face impaired problem, and then improve the crudy of device, and handle 6 also to make staff exert a force more convenient.
Operation principle of the present utility model is: the utility model passes through rotary handle, expansion head then can pull to the right by screw rod, sleeve is under the expansionary force expanding head, workpiece is fixed, can not loosen, also can not because of clamping loose shift, fixation, cutter can in outer workpiece freely-movable, thus realize one-time positioning and can process at the multiple end face of part, thus when ensure that work pieces process, there is higher axiality, guarantee work pieces process quality, pad is provided with in addition outside described sleeve, the material of pad is elastomeric material, the effect of pad be convenient to anti-locking apparatus add clamping of workpieces time cause clamping face impaired problem, and then improve the crudy of device, and handle also to make staff exert a force more convenient.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this description is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should by description integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
