Description
Technical field
The utility model relates to blade processing technique field, more particularly, relates to the frock of the movable plug of mechanical type in a kind of disc-like tool sharpening process.
Background technology
Along with social development, mechanical industry also enters into micron order ultraprecision to the machining accuracy of workpiece and controls the stage.In metal itemize industry, the slitting cylinder blade of cutting for the metal forming class (as Copper Foil, aluminium foil etc.) of two zero level thickness, requiring has very high axiality and flatness to control the shearing quality of product.In fine finishining industry at home, flatness can reach the requirement of product micron order by grinding, and the axiality of slitting cylinder blade is a bottleneck of domestic production producer all the time.
At present, mostly domestic cylinder blade manufacturer is cylinder blade to be set on the machining shaft that diameter combines with cylinder blade internal diameter and to process.Yet, due to mismachining tolerance or use wearing and tearing for a long time, between cylinder blade internal diameter and machining shaft cylindrical, always there is certain error, internal diameter and its machining shaft cylindrical of cylinder blade cannot be closely cooperated, cylinder blade can not get accurate clamping, the cylinder blade that processing obtains cannot meet its requirement to coaxial accuracy, and this error of how eliminating between cylinder blade internal diameter and machining shaft cylindrical is the difficult problem that industry is difficult to capture always.Therefore, such blade relies on for a long time from Germany and Japan and other countries import always, brings very high production cost to metal itemize industry.
Through retrieval, axiality about disc-like tool sharpening is controlled, existing related art scheme is open, as China Patent No.: ZL200910252257.5, Granted publication day is: on September 26th, 2012, invention and created name is: Workpiece internal-external circle concentricity lathe turning tooling and using method thereof, this application case relates to a kind of Workpiece internal-external circle concentricity lathe turning tooling and using method thereof, Workpiece internal-external circle concentricity lathe turning tooling is by clamping body, tensioner part, the baffle plate adjacent with tensioner part and forming through the tight fixed bolt of baffle plate, described clamping body coordinates section by machine tool chief axis successively, changeover portion, workpiece construction section and conical section form, described tensioner part is comprised of with the elastic ring that is arranged at tightening piece outer round surface the gapped tightening piece of tool of three above same structures, each tightening piece has the high precision excircle anchor ring adapting with workpiece inner circle after high accuracy inner ring surface that the conical section with clamping body adapts and tensioner, the middle part of the cylindrical anchor ring of each tightening piece has the annular groove of placing elastic ring.The internal-external circle concentricity that this application case can meet the rear workpiece of processing to a certain extent meets required precision, but this application case has the following disadvantages: the workpiece construction section size of (1) this application case is fixed, determined that the inner hole of workpiece aperture being mounted thereon can only change in very little scope, therefore, the range of application of this axiality processing tool is narrow; (2) this application case, only by tensioner is carried out in workpiece one end, realizes the clamping of workpiece is fixed, and fixed effect is undesirable, and the machining accuracy of workpiece axiality is difficult to guarantee.
In addition, China Patent No.: ZL201320546208.4, Granted publication day is: on February 5th, 2014, invention and created name is: a kind of slitting cylinder blade axiality is precisely processed special tooling, this application case discloses a kind of slitting cylinder blade axiality and has precisely processed special tooling, it comprises plug main shaft, unload covering device, open conical sleeve, tapered sleeve fixed mechanism and cutter hub hold-down mechanism, plug main shaft is disposed with pressing plate along its length, unload covering device construction section, tapering transition section, the first thread segment and the second thread segment, unload covering device and be positioned at the right side of pressing plate, this unloads covering device and is sleeved on that to unload covering device construction section outside, open conical sleeve is sleeved on the outside of tapering transition section, tapered sleeve fixed mechanism is flexibly connected with above-mentioned the first thread segment screw thread, this tapered sleeve fixed mechanism permanent opening tapered sleeve, cutter hub hold-down mechanism is flexibly connected with the second thread segment screw thread, and this cutter hub hold-down mechanism is used for being fixed slitting cylinder blade.Although this application case has solved the precision problem of cylinder blade axiality processing to a certain extent, but the deformation degree of the strip cutting groove of open conical sleeve is limited, be difficult to meet the axle degree processing needs of multiple caliber cylinder blade, and there is no self-checking device, be difficult to keep for a long time high precision, also need further to improve.
