The utility model discloses an adopt abutment sleeve to realize the fixed of work piece and location, adopt the thimble fix with the tradition and compare with the positioner that fix a position, can prevent effectively that the work piece appearance from squinting and the phenomenon of slippage to improve stability and concentricity in the work piece course of working, and then helped the improvement of work piece machining precision.
Description
Technical field
The utility model belongs to gear machining apparatus technical field, relates to a kind of positioner of gear-shaping machine.
Background technology
In engineering goods, the product of gear class account for major part, general is all fix cutter by tool driving device in gear-shaping machine, workpiece to be processed is placed on the table, locate gear by positioner, after worktable rotary then by the three-dimensional such as X, Y, Z that controls rotary cutter and the workpiece of rotation engage each other make cutter on the axle of workpiece reciprocating by Workpiece shaping required for gear shape.
Such as, Authorization Notice No. is that the patent of invention of CN102366845A discloses a kind of gear-shaping machine, it comprises lathe bed and is arranged on left column, right column, the workbench that can rotate, positioner, horizontal mobile device, cutter tourelle, three-dimensional mobile device and the driving mechanism on lathe bed, whole gear-shaping machine is equipped with numerical control operating interface and programming special-purpose software, as long as add the basic parameter inserting gear man-hour, just automatically can control each device and to have cooperatively interacted Gear Processing.
Although the positioner adopted in this gear-shaping machine can realize the fixing of workpiece and location, but this positioner realizes the fixing of workpiece and location mainly through thimble, be easy in actual use occur the phenomenon such as workpiece position error, workpiece slippage, thus the precision of work pieces process can be had a strong impact on.
In sum, in order to solve the technical problem of above-mentioned positioner, need to design that a kind of structure is simple, stability is high, the positioner of good concentricity.
Utility model content
The purpose of this utility model is the problems referred to above existed for prior art, proposes that a kind of structure is simple, stability is high, the positioner of the gear-shaping machine of good concentricity.
The purpose of this utility model realizes by following technical proposal: a kind of positioner of gear-shaping machine, comprise locating rack and the abutment sleeve with through hole, described abutment sleeve is arranged on locating rack inside, clutch shaft bearing, stop sleeve and 3 the second bearings are provided with from top to bottom between described abutment sleeve and locating rack, described locating rack lower end is fixedly connected with bottom end cover, the upper end of described locating rack is bolted with upper end cover, and described clutch shaft bearing, stop sleeve and 3 the second bearings are pressed in locating rack by the cooperation of upper end cover and bottom end cover.
Here abutment sleeve is adopted to realize the fixing of workpiece and location, when workpiece is inserted into abutment sleeve from abutment sleeve lower end, abutment sleeve effectively can realize the location to workpiece by inner locating hole, adopt thimble to be fixed with tradition to compare with the positioner of locating, can effectively prevent workpiece from occurring the phenomenon of skew and slippage, by adopting 3 the second bearings, abutment sleeve can be avoided as much as possible to occur laterally offset phenomenon, thus effectively can ensure the concentricity of abutment sleeve, improve the precision of work pieces process.
The measure taked for optimizing such scheme specifically comprises:
In the positioner of above-mentioned a kind of gear-shaping machine, described through hole (8) comprises conical hole and straight hole, and described straight hole is crossing with the vertex of a cone of conical hole.
Here by a part for through hole being set to lower large little conical surface shape, thus the workpiece of various outer diameter can be adapted to, realizing the fixing and location of the workpiece to various outer diameter, considerably increasing practicality.
In the positioner of above-mentioned a kind of gear-shaping machine, described bottom end cover and locating rack are bolted.
Here the structure adopting bottom end cover and locating rack to be bolted, brings conveniently to the installation and removal of abutment sleeve, clutch shaft bearing, stop sleeve, several second bearings and bottom end cover, contributes to maintenance and the maintenance of positioner.
Compared with prior art, the beneficial effects of the utility model are: realize the fixing of workpiece and location by adopting abutment sleeve, adopt thimble to be fixed with tradition to compare with the positioner of locating, can effectively prevent workpiece from occurring the phenomenon of skew and slippage, thus the stability that improve in workpiece process and concentricity, and then contribute to the raising of Workpiece Machining Accuracy.
