Description
Technical field
The utility model relates to a kind of fixture, is specifically related to a kind of large aperture gear shaft gear grinding clamp.
Background technology
Roll flute is the main manufacturing process of one obtaining high accuracy quenching hard gear, and gear shaft is as the widely used gear drive part of one, its precision mainly ensures, if clamp precision does not reach by machine tool accuracy and clamp precision, machine tool accuracy is high again, and the precision of gear shaft also cannot improve.At present, be all first adopt Double Tops point by workpiece pre-tightening when processing large and small aperture gear shaft, then roll flute on grinding machine.In actual process, we find that said method compares and are suitable for machining small footpath gear shaft.But, not just very suitable for processing large aperture gear shaft, because Double Tops point is inadequate to the chucking power of workpiece, being so just easy to cause workpiece and workbench to rotate asynchronous, and then cause the machining accuracy of the flank of tooth to be difficult to ensure.
Utility model content
For above-mentioned deficiency of the prior art, the utility model main purpose is to provide a kind of gear grinding clamp for processing large aperture gear shaft.
To achieve these goals, the technical solution adopted in the utility model is as follows:
Large aperture gear shaft gear grinding clamp, comprises clamp body, axle, tapered sleeve and nut, and one end of described clamp body is provided with locating hole, and the other end of clamp body is taper seat; One end of described axle and the other end of clamp body are fixed, axle comprises nut linkage section, tapered sleeve construction section and trade union college section, trade union college section is positioned at the one end near clamp body, nut linkage section is positioned at the one end away from clamp body, tapered sleeve construction section, between trade union college section and nut linkage section, nut linkage section is provided with external screw thread; Described tapered sleeve is set on axle tapered sleeve construction section, and tapered sleeve is being just taper seat to one end of clamp body; The endoporus of described nut is shoulder hole, its path section is provided with the internal thread matched with spindle nut linkage section, the aperture of its large footpath section is greater than the diameter of axle tapered sleeve construction section, nut and spindle nut linkage section threaded engagement, and one end of its large footpath section withstands on the corresponding end face of tapered sleeve.
Further, the tapering of described clamp body taper seat is 60 °, and the tapering of described tapered sleeve taper seat is 60 °.
Relative to prior art, the utility model has following beneficial effect:
The utility model is fixed the workpiece be installed in axle by the taper seat of clamp body and tapered sleeve, it is fixed, clamping is easy, structure is simple, workpiece and axle synchronous axial system can be made, ensure workpiece Gear shape process precision, avoid prior art because the holder power quality problems caused that cause workpiece to loosen not, and owing to being Internal hole positioning, any damage can not be produced to workpiece.
Accompanying drawing explanation
Fig. 1 is the utility model using state structural representation;
Fig. 2 is clamp body and mandrel structure schematic diagram;

Wherein, 1 is clamp body, and 11 is locating hole, and 2 is axle, and 21 is trade union college section, and 22 is tapered sleeve construction section, and 23 is nut linkage section, and 3 is tapered sleeve, and 4 is nut, and 5 is workpiece, and 6 is clamping device, and 7 is top on lathe, and 8 is top under lathe.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
See Fig. 1 ~ Fig. 4: large aperture gear shaft gear grinding clamp comprises clamp body 1, axle 2, tapered sleeve 3 and nut 4.The right-hand member of clamp body 1 is provided with locating hole 11, and the left end of clamp body 1 is taper seat, and its tapering is 60 °.The right-hand member of axle 2 and the left end of clamp body 1 are fixed, and axle 2 comprises nut linkage section 23, tapered sleeve construction section 22 and trade union college section 21 from left to right successively, and nut linkage section 23 is provided with external screw thread.Tapered sleeve 3 is set on axle tapered sleeve construction section 22, and the right-hand member (namely just to one end of clamp body 1) of tapered sleeve 3 is taper seat, and its tapering is 60 °.The endoporus of nut 4 is shoulder hole, and its path section is provided with the internal thread matched with spindle nut linkage section 23, and the aperture of its large footpath section is greater than the diameter of axle tapered sleeve construction section 22; Nut 4 and spindle nut linkage section 23 threaded engagement, one end of its large footpath section withstands in tapered sleeve 3 corresponding end.
During use, the endoporus at workpiece 5 two ends is set to the conical surface matched with fixture, workpiece 5 is set in the trade union college section 21 of axle 2, its right-hand member coordinates with the taper seat of clamp body 1, left end coordinates with the taper seat of tapered sleeve 3, is then arranged on the nut linkage section 23 of axle by nut 4, and the large footpath Duan Duan of nut 4 withstands on the corresponding end of tapered sleeve 3, make the taper seat of tapered sleeve 3 and the taper seat of clamp body 1 embed workpiece 5 endoporus, workpiece 5 is fixed between tapered sleeve 3 and clamp body 1.The right-hand member of clamp body 1 is fixed on lathe by grinding machine bed clamping device 6, and top 8 locating holes 11 withstanding on clamp body 1 right-hand member under lathe, on lathe, top 7 withstand on axle 2 left end, are fixed on grinding machine bed by fixture.
The utility model is fixed the workpiece be installed in axle by the taper seat of clamp body and tapered sleeve, it is fixed, clamping is easy, structure is simple, workpiece and axle synchronous axial system can be made, ensure workpiece Gear shape process precision, avoid prior art because the holder power quality problems caused that cause workpiece to loosen not, and owing to being Internal hole positioning, any damage can not be produced to workpiece.
Finally it should be noted that, above embodiment is only in order to illustrate the technical solution of the utility model but not restriction technologies scheme, although applicant has been described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, those are modified to the technical solution of the utility model or equivalent replacement, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of right of the present utility model.
