Description
Technical field
The present invention relates to a kind of gear hobbing mould, be specifically related to a kind of top for the gear hobbing mould.
Background technology
The gear hobbing mould is a kind of instrument of realizing that workpiece is connected with workbench, and workpiece is vertically placed, and lower end is fixing with gear hobbing mould location, and locate with the thimble of tail stock for machine tool upper end, and work table rotation drives the workpiece revolution, thereby completes the processing of workpiece external splines.The gear hobbing mould is mainly by die holder, the mould body, the spiral shell handle, mandrel, anti-turn screw, top and steel ball form, during use, be mainly manually by handle, to rotate the spiral shell handle, the spiral shell handle pulls mandrel to move downward, mandrel drives top and moves downward, the conical surface extruding steel ball of lower end, top outwards moves along hole with it mould, steel ball extruding workpiece inwall is until workpiece and the locking of gear hobbing mould, because steel ball is that point contacts with coming directly towards between the conical surface, the power transmission is more concentrated each other, the intensity of steel ball material is far longer than the intensity of heading material, in use procedure, the top bottom conical surface destruction that often can be worn, cause the gear hobbing mould can not lock workpiece fully, affect product quality, change simultaneously also inconvenient.
Summary of the invention
The object of the present invention is to provide a kind of top for the gear hobbing mould, location, this top reliable and safeguard convenient.
For achieving the above object, the present invention has adopted following technical scheme: comprise the top body, the conical surface section that described top body matches by the cylindrical section matched with the mould body, with mould steel ball with it and the thread segment be connected with mandrel form, described conical surface section circumferentially evenly is provided with and inserts along it, and described inserting contacts with mould steel ball formation line with it.
The described face matched with steel ball of inserting is the cambered surface concaved, and the radian of its cambered surface and the radian of steel ball match.
Described dismountable being fixed on the body of top of inserting.
Described top of inserting is resisted against the lower surface of cylindrical section, and described bottom of inserting is fixed by the locking nut be arranged on thread segment, inserts and is close on the conical surface of conical surface section under the pretightning force effect of locking nut.
Described conical surface section also is provided with the annular stator of fixedly inserting, and described stator is provided with for the insert groove of inserting and snapping in, and described insert groove circumferentially is evenly arranged along stator, and the number of insert groove setting matches with the number of inserting.
Described top of inserting 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 shape with the inclined-plane at the top of inserting and contacts cooperation.
Described bottom of inserting is provided with the Plug Division of matching with locking nut.
As shown from the above technical solution, the present invention is by arranging and insert on the body of top, insert with steel ball between contact by the contact of original point and become the line contact, disperseed the transmission of power, make the structure of whole top body more stable, the insert structure come directly towards simultaneously on body is simple, and easy removal is convenient to change.

The specific embodiment
The present invention will be further described below in conjunction with accompanying drawing:
A kind of top for the gear hobbing mould shown in Figure 8 as shown in Figure 1, Figure 2,, comprise top body 1, the conical surface section 12 that top body 1 matches by the cylindrical section 11 matched with mould body 5, with mould steel ball 6 with it and the thread segment 13 be connected with mandrel 7 form, conical surface section 12 circumferentially evenly is provided with and inserts 2 along it, inserts 2 with mould steel ball with it, to form line and contact.
Further, as shown in Fig. 5-7, the cambered surface of 2 faces that match with steel ball 6 21 for concaving of inserting, the radian of its cambered surface and the radian of steel ball match.Setting is inserted and 2 not only can be made to insert and 2 with steel ball, form line and contact to disperse mandrel to drive the transmission of top body power when descending, can also be reduced on the conical surface section 12 of top body 1 the directly difficulty of processing cambered surface.
Further, insert 2 dismountable are fixed on the top body 1 on.Top body 1 only need to 2 be changed inserting afterwards in wearing and tearing like this, and dismountable fixed form makes the replacing of inserting simple, convenient, fast, has also saved production cost simultaneously.
Particularly, 2 the top of inserting is resisted against the lower surface of cylindrical section 11, and 2 the bottom of inserting is fixing by the locking nut 4 be arranged on thread segment 13, is close on the conical surface of conical surface section 12 under 2 effects of the pretightning force at locking nut 4 of inserting.Namely by locking nut 4, fixedly insert 2, and make to insert 2 with the top body 1 be adjacent to fixing.
Preferably, insert 2 top 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 shape with the inclined-plane 22 at 2 tops of inserting and contacts cooperation, namely the lower surface of cylindrical section 11 is provided with the arc groove 111 with gradient, and this arc groove 111 matches fixing with the inclined-plane 22 at 2 tops of inserting; Insert 2 bottom 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 also is provided with 2 the annular stator 3 of fixedly inserting, and stator 3 is provided with for inserting 2 insert grooves that snap in 31, insert groove 31 circumferentially is evenly arranged along stator 3, and the number that arranges of insert groove 31 matches with 2 the number of inserting.Namely come directly towards on the conical surface section 12 of body 1 and also be provided with the circumferentially insert groove 31 of positioning insert 2, can, from circumferentially to inserting, 2 positioning, make the structure of inserting more stable.
Beneficial effect of the present invention is: 1) contacting by a contact between body and the steel ball of top becomes the line contact, disperseed mandrel to drive the transmission of top body power when descending; 2) insert and can be reduced in the difficulty of directly processing cambered surface on the conical surface that comes directly towards body; 3) on cylindrical section, with the inclined-plane at the top of inserting, form wedge surface with gradient arc groove and coordinate, can be close to the conical surface section that comes directly towards body after the pretightning force that is subject to locking nut that makes to insert, make structure more stable; 4) stator can be from coming directly towards circumferentially accurately locating inserting of body; 5) insert wearing and tearing after fast changeable, cost is low.
Above-described embodiment is described the preferred embodiment of the present invention; not scope of the present invention is limited; design under the prerequisite of spirit not breaking away from the present invention; various distortion and improvement that those of ordinary skills make technical scheme of the present invention, all should fall in the definite protection domain of the claims in the present invention book.
