Description
Technical field
The present invention relates to a kind of gear hobbing mould, be specifically related to a kind of top for gear hobbing mould.
Background technology
Gear hobbing mould is used to realize a kind of instrument that workpiece is connected with workbench, and workplace vertical is placed, and lower end is fixing with gear hobbing mould location, and the thimble location of upper end tail stock for machine tool, work table rotation drives workpiece revolution, thus completes the processing of workpiece external splines.Gear hobbing mould is primarily of die holder, mould body, spiral shell handle, mandrel, anti-turn screw, top and steel ball composition, mainly artificial by handle rotation spiral shell handle during use, spiral shell handle pulls mandrel to move downward, mandrel drives top to move downward, the conical surface extruding steel ball of lower end, top outwards moves along hole with it mould, steel ball extruding workpiece inner wall is until workpiece and gear hobbing mould are locked, due to steel ball and top the conical surface between be point cantact, mutual power transmission is more concentrated, the intensity of steel ball material is far longer than the intensity of heading material, in use procedure, top lower tapered surface often can be worn destruction, cause gear hobbing mould can not lock workpiece completely, affect product quality, change also inconvenient simultaneously.
Summary of the invention
The object of the present invention is to provide a kind of top for gear hobbing mould, location, this top reliable and safeguard convenient.
For achieving the above object, present invention employs following technical scheme: comprise top body, described top body is by the cylindrical section matched with mould body, the conical surface section matched with mould steel ball with it and the thread segment be connected with mandrel form, described conical surface section is evenly provided with insert along its circumference, described insert and mould steel ball with it forms linear contact lay, described insert is dismountable to be fixed on the body of top, the top of described insert is resisted against the lower surface of cylindrical section, the bottom of described insert is fixed by the locking nut be arranged on thread segment, insert is close on the conical surface of conical surface section under the pretightning force effect of locking nut, described conical surface section is also provided with the annular stator of fixing insert, described stator is provided with the insert groove snapped in for insert, described insert groove is evenly arranged along the circumference of stator, and the number of insert groove setting and the number of insert match.
The face that described insert matches with steel ball is the cambered surface concaved, and the radian of its cambered surface and the radian of steel ball match.
The top of described insert is an inclined-plane, and the lower surface of described cylindrical section is provided with the arc groove of inside oblique setting, and described arc groove forms wedge contact with the inclined-plane at insert top and coordinates.
The bottom of described insert is provided with the Plug Division of matching with locking nut.
As shown from the above technical solution, the present invention by arranging insert on the body of top, contact between insert and steel ball becomes linear contact lay by original point cantact, disperse the transmission of power, make the structure of whole top body more stable, the insert structure simultaneously come directly towards on body is simple, easy removal, is convenient to change.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described:
As shown in Figure 1, Figure 2, a kind of top for gear hobbing mould shown in Fig. 8, comprise top body 1, top body 1 is made up of the cylindrical section 11 matched with mould body 5, the conical surface section 12 matched with mould steel ball 6 with it and the thread segment 13 that is connected with mandrel 7, conical surface section 12 is evenly provided with insert 2 along its circumference, and insert 2 and mould steel ball with it form linear contact lay.
Further, as illustrated in figs. 5-7, the cambered surface of face 21 for concaving that insert 2 matches with steel ball 6, the radian of its cambered surface and the radian of steel ball match.The transmission of power when insert 2 not only can make insert 2 and steel ball form linear contact lay disperse mandrel to drive to come directly towards body descending is set, can also be reduced in come directly towards body 1 conical surface section 12 on direct difficulty of processing cambered surface.
Further, insert 2 is dismountable is fixed on the body 1 of top.Such top body 1 only needs to change insert 2 upon wear, and dismountable fixed form makes the replacing of insert simple, convenient, fast, also saves production cost simultaneously.
Particularly, the top of insert 2 is resisted against the lower surface of cylindrical section 11, and the bottom of insert 2 is fixed by the locking nut 4 be arranged on thread segment 13, and insert 2 is close on the conical surface of conical surface section 12 under the pretightning force effect of locking nut 4.Namely fix insert 2 by locking nut 4, and make insert 2 be adjacent to fixing with top body 1.
Preferably, the top of insert 2 is an inclined-plane 22, the lower surface of cylindrical section 11 is provided with the arc groove 111 of inside oblique setting, arc groove 111 forms wedge contact with the inclined-plane 22 at insert 2 top and coordinates, namely the lower surface of cylindrical section 11 is provided with the arc groove 111 of band gradient, and this arc groove 111 matches fixing with the inclined-plane 22 at insert 2 top; The bottom of insert 2 is provided with the Plug Division 23 of matching with locking nut 4.
Further, as shown in Figure 3, Figure 4, conical surface section 12 is also provided with the annular stator 3 of fixing insert 2, and stator 3 is provided with the insert groove 31 snapped in for insert 2, insert groove 31 is evenly arranged along the circumference of stator 3, and the number of insert groove 31 setting and the number of insert 2 match.The conical surface section 12 namely coming directly towards body 1 is also provided with can the insert groove 31 of circumferential positioning insert 2, can position, make the structure of insert more stable from circumference to insert 2.
Beneficial effect of the present invention is: 1) contact come directly towards between body and steel ball becomes linear contact lay by point cantact, the transmission of power when having disperseed mandrel to drive top body descending; 2) insert can be reduced in top body the conical surface on the difficulty of direct processing cambered surface; 3) cylindrical section forms wedge surface with gradient arc groove with the inclined-plane at insert top to coordinate, the conical surface section of top body can be close to after making insert be subject to the pretightning force of locking nut, make structure more stable; 4) stator accurately can be located from the circumference of top body insert; 5) fast changeable after insert wearing and tearing, cost is low.
Above-described embodiment is only be described the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; the various distortion that those of ordinary skill in the art make technical scheme of the present invention and improvement, all should fall in protection domain that claims of the present invention determines.
