Description

A kind of numerical control machine tool clamp with elastic groove
Technical field
The utility model relates to a kind of Digit Control Machine Tool relevant device, specifically a kind of numerical control machine tool clamp with elastic groove.
Background technology
Current thin cylinder part is widely used in the field such as machining and life production, it has lightweight, compact conformation, take up room the advantage such as little, but the machining accuracy of thin-wall circular tube kind part is wayward, this kind of part uses lathe process usually, and its main processes is: 1) planar end surface, thick bore which; 2) rough turn cylindrical; 3) smart bore which; 4) fine turning outer circle; 5) planar end surface.In prior art, problems faced is: this type of part often occurs that after turning the coaxiality deviation of cylindrical and endoporus is large, the circularity of endoporus and cylindrical and the problem such as cylindricity is overproof, traditional fixture comprises three-jaw card etc., with playing nip cylinders, easy damage cylinder outer wall, although also have the fixture that some point cantact adopting rigidity are fixing, no matter but be fixing inner circle or cylindrical, due to clamping error and clamping force uneven, capital makes workpiece produce incomparable inconsistent elastic deformation, in addition point cantact is fixing also can make heat in metal cutting conduct unbalanced generation thermal deformation difference, cause workpiece in completion of processing from after fixture unloads, its internal stress can be caused to redistribute because of cancelling external force and uneven cooling, workpiece produces secondary deformation, greatly reduce the machining accuracy of thin cylinder part, in order to the existing numerical control machine tool clamp finally that solves the problem, but the problem that this fixture often causes work piece surface impaired when clamping workpiece, and the end face of forward block in device is rectangle, cause device feature frictional dissipation excessive, service life is low, the noise produced is large.
Utility model content
The purpose of this utility model is to provide a kind of numerical control machine tool clamp with elastic groove, 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 numerical control machine tool clamp with elastic groove, comprise connector, clamping body, handle, rotary body, forward block, fastening tail, band elastic groove, pad and transition face, described clamping body head is provided with connector, clamping body afterbody is provided with fastening tail, described clamping body afterbody is provided with band elastic groove, described clamping body afterbody inwall is provided with pad, rotary body is provided with outside described clamping body, rotary body upper end is provided with handle, described rotary body tail end is provided with forward block, be provided with ball between forward block and rotary body, forward block right side is provided with transition face.
As further program of the utility model: be matched in clearance between described forward block and clamping body.
As further program of the utility model: described transition face is arc surface.
As further program of the utility model: be threaded connection between described rotary body and clamping body.
As further program of the utility model: the material of described pad is elastomeric material.
As further program of the utility model: the cross section of described fastening tail is taper surface.
Compared with prior art, the beneficial effects of the utility model are: the utility model rotates rotary body by handle, and then rotary body promotion forward block is moved right, clamping body afterbody internal diameter reduces, and then workpiece is fixedly clamped, rotating backward rotary body just makes workpiece unclamp, clamping body afterbody inwall is provided with pad, the material of pad is elastomeric material, the effect of pad is anti-locking apparatus defective work piece when clamping work pieces, and then improve the quality of workpiece, forward block right side is provided with transition face simultaneously, transition face is arc surface, the resistance between forward block and fastening tail is reduced during the effect in excessive face, and then reduce the loss of device feature, reduce the noise produced in forward block progradation, improve the service life of device, apparatus structure is simple, rationally,
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 numerical control machine tool clamp with elastic groove, comprise connector 1, clamping body 2, handle 3, rotary body 4, forward block 6, fastening tail 7, band elastic groove 8, pad 9 and transition face 10, described clamping body 2 head is provided with connector 1, be threaded connection between connector 1 and clamping body 2, described clamping body 2 afterbody is provided with fastening tail 7, the cross section of fastening tail 7 is taper surface, described clamping body 2 afterbody is provided with band elastic groove 8, band elastic groove 8 array distribution is at clamping body 2 afterbody, described clamping body 2 afterbody inwall is provided with pad 9, the material of pad 9 is elastomeric material, the effect of pad 9 is anti-locking apparatus defective work pieces when clamping work pieces, and then improve the quality of workpiece, rotary body 4 is provided with outside described clamping body 2, rotary body 4 upper end is provided with handle 3, be threaded connection between rotary body 4 and clamping body 2, described rotary body 4 tail end is provided with forward block 6, ball 5 is provided with between forward block 6 and rotary body 4, be matched in clearance between described forward block 6 and clamping body 2, forward block 6 right side is provided with transition face 10, transition face 10 is arc surface, the resistance between forward block 10 and fastening tail 7 is reduced during the effect in excessive face 10, and then reduce the loss of device feature, reduce the noise produced in forward block 10 progradation, improve the service life of device, when needs clamping work pieces, rotary body 4 is rotated by handle 3, and then make rotary body 4 promote forward block 6 to move right, and then workpiece is fixedly clamped, rotating backward rotary body 4 just makes workpiece unclamp.
