Description
Technical field
This utility model relates to numerical control machine tool field, is specifically related to a kind of vertical car differential headstock.
Background technology
Last century the eighties, domestic with Japan's product little vertical car of single-column (national numbering CK5112B), first drawing is made at force weight, its structure is as shown in Figure 1, its main transmission is by driving gear wheel under floral disc in the incoming differential main-gear box of belt so as to transmission, and the big belt pulley off-load on change speed gear box is on casing, but one end that its center-wheel arbor is in casing is cantilevered fashion is connected with differential attachment, this cantilever design is poor stability when machine vibration, it is easy to cause mismachining tolerance.
Utility model content
This utility model provides a kind of vertical car differential headstock, it is possible to effectively solving center-wheel arbor one end is that cantilever causes poor stability, the problem that machining accuracy is low.
The technical solution of the utility model is in that: include casing, belt wheel, internal tooth wheel disc, first gear, second gear, center-wheel arbor, differential frame, casing lower end is located at by described belt wheel, can rotate around cabinet exterior, center-wheel arbor is located in casing, lower end and belt wheel are coaxially fixed, upper end is provided with the first gear, casing upper end is located at by described internal tooth wheel disc, described second gear and the first gear and internal tooth wheel disc are simultaneously engaged, described differential frame and center-wheel arbor are coaxially disposed, and fix with the second gear, the bindiny mechanism being connected by center-wheel arbor it is provided with differential frame between described center-wheel arbor with differential frame.
Preferred as such scheme, described bindiny mechanism includes the groove offered differential frame lower surface, the bearing being located at groove inner wall and the spindle nose being set in bearing, and described spindle nose and center-wheel arbor are structure as a whole.
Another kind as such scheme is preferred, described bindiny mechanism includes the groove offered differential frame lower surface, the bearing being located at groove inner wall and the spindle nose being set in bearing, described center-wheel arbor upper surface also offers groove, and described spindle nose lower end is fixedly arranged in the groove of central shaft.
As such scheme it is preferred that, be provided with multiple second gear between described first gear and internal tooth wheel disc, be uniformly distributed in internal tooth wheel disc, and multiple second gear is all fixing with differential frame is connected.
The beneficial effects of the utility model are in that: this utility model sets up bindiny mechanism between center-wheel arbor and differential frame can be effectively improved stability and the machining accuracy of vertical car overall operation, is conducive to marketing.

Detailed description of the invention
Of the present utility model embodiment is described in detail below in conjunction with accompanying drawing.
Embodiment one
Such as Fig. 2, shown in Fig. 3, the structure of the present embodiment includes casing 3, belt wheel 1, internal tooth wheel disc 5, first gear 6, second gear 4, center-wheel arbor 2, differential frame 7, casing 3 lower end is located at by described belt wheel 1, can rotate around cabinet exterior, center-wheel arbor 2 is located in casing 3, lower end and belt wheel 1 are coaxially fixed, upper end is provided with the first gear 6, casing 3 upper end is located at by described internal tooth wheel disc 5, described second gear 4 and the first gear 6 and internal tooth wheel disc 5 are simultaneously engaged, described differential frame 7 is coaxially disposed with center-wheel arbor 2, and fix with the second gear 4, the bindiny mechanism being connected by center-wheel arbor 2 it is provided with differential frame 7 between described center-wheel arbor 2 with differential frame 7.Described bindiny mechanism includes the groove 11 offered differential frame 7 lower surface, the bearing 10 being located at groove 11 inwall and the spindle nose 9 being set in bearing 10, and described center-wheel arbor 2 upper surface also offers groove 8, and described spindle nose 9 lower end is fixedly arranged in the groove 8 of central shaft 2.
In the present embodiment, it is provided with multiple second gear 4 between described first gear 6 and internal tooth wheel disc 5, is uniformly distributed in internal tooth wheel disc 5, and multiple second gear 4 is all fixed with differential frame 7 and is connected.
In the present embodiment, it is connected by the bindiny mechanism with spindle nose and bearing between differential frame and center-wheel arbor, solves the problem that center-wheel arbor one end is cantilever design and instability, substantially increase the machining accuracy of lathe.
Embodiment two
As shown in Figure 4, for another kind of embodiment of the present utility model, on the basis of above-described embodiment one, the structure of described bindiny mechanism is made further improvements, described bindiny mechanism includes the groove 11 offered differential frame 7 lower surface, the bearing 10 being located at groove 11 inwall and the spindle nose 9 being set in bearing 10, and described spindle nose 9 is structure as a whole with center-wheel arbor 2.
For existing vertical car differential headstock, the structure of above-described embodiment one can be adopted, namely at existing center-wheel arbor end opens groove, spindle nose is arranged in the groove of center-wheel arbor.The technique of the reforming mode of this pair existing vertical car differential headstock is simple, and improvement cost is low, is conducive to marketing.For the vertical car differential headstock of coming of new, the structure of above-described embodiment two can be adopted, namely directly process the center-wheel arbor with spindle nose.
In sum, due to this Curve guide impeller, substantially original structure carries out the size without influence on original structure and change in location, only on differential frame, carry out supplementary processing, a little spindle nose has been inlayed at central gear end face, if on the lathe of new material, former central gear blank can be lengthened 30-35mm.
