The present invention discloses a kind of Dual Drive gear hobbing machine worktable, and wherein indexing worm is by bearings on workbench housing, and the input of indexing worm is coaxially connected with the servo motor output shaft on workbench housing; Dividing worm wheel often engages with indexing worm, and be solidly set on work top, work top is rotatably supported on workbench housing, the first bevel gear on indexing worm often engages with the second bevel gear, second bevel gear and the 3rd bevel gear are solidly set on transition axis two ends, and transition axis by bearings on workbench housing; 3rd bevel gear often engages with the 4th bevel gear on damping worm screw, and damping worm screw is by bearings on workbench housing, and damping worm screw is parallel with indexing worm, and often engages with dividing worm wheel.The present invention eliminates the sideshake between indexing worm and dividing worm wheel effectively by damping worm screw, so by the little change customer service defect of prior art indexing accuracy difference effectively, and energy quick rotation work top.

Description

A kind of Dual Drive gear hobbing machine worktable
Technical field
The invention belongs to gear-hobbing machine field, particularly relate to a kind of Dual Drive gear hobbing machine worktable.
Background technology
Workbench is the important feature of gear-hobbing machine, its precision and the machining accuracy of workpiece closely related, and the precision of workbench is relevant with the indexing accuracy of dividing worm wheel worm gear pair.At present, existing workbench is all single driving, and namely an indexing worm drives an indexing worm.
The defect of prior art is: 1, owing to having sideshake between dividing worm wheel worm gear pair, this sideshake can affect indexing accuracy, thus affects the precision of workbench; 2, existing structure cannot quick rotation worm gear and work top.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of high-precision Dual Drive gear hobbing machine worktable.
Technical scheme of the present invention is as follows: a kind of Dual Drive gear hobbing machine worktable, comprise indexing worm (1) and dividing worm wheel (4), wherein indexing worm (1) is by bearings on workbench housing (2), and the input of this indexing worm is coaxially connected with servomotor (3) output shaft on workbench housing (2); Described dividing worm wheel (4) often engages with indexing worm (1), and be solidly set on work top (5), this work top is rotatably supported on described workbench housing (2), it is characterized in that: the first bevel gear (6) on described indexing worm (1) often engages with the second bevel gear (7), this second bevel gear and the 3rd bevel gear (8) are solidly set on transition axis (9) two ends, and transition axis by bearings on described workbench housing (2); Described 3rd bevel gear (8) often engages with the 4th bevel gear (11) on damping worm screw (10), this damping worm screw by bearings on described workbench housing (2), and damping worm screw (10) is parallel with described indexing worm (1), and often engage with described dividing worm wheel (4).
In said structure, the present invention has set up the first bevel gear (6), the second bevel gear (7), the 3rd bevel gear (8), the 4th bevel gear (11), transition axis (9) and damping worm screw (10), thus come to form damping to dividing worm wheel (4) by damping worm screw (10), thus eliminate the sideshake between indexing worm (1) and dividing worm wheel (4).
Adopt above structure, the present invention eliminates the sideshake between indexing worm and dividing worm wheel effectively by damping worm screw, and so by the little change customer service defect of prior art indexing accuracy difference effectively, and structure of the present invention is simply, easy to implement.
As preferably, the work top (5) of described dividing worm wheel (4) below is installed with a small gear (12), this small gear often engages with small worm (13), and small worm by bearings on described workbench housing (2), and the input of small worm is coaxially connected with the output of drive motors (14).
Adopt said structure, when drive motors (14) drives small worm (13) to rotate, small gear (12) quick rotation can be driven, thus drive work top (5) to follow dividing worm wheel (4) quick rotation together.
Beneficial effect: the present invention eliminates the sideshake between indexing worm and dividing worm wheel effectively by damping worm screw, so by the little change customer service defect of prior art indexing accuracy difference effectively, and energy quick rotation work top, and structure of the present invention is simple, easy to implement.
Accompanying drawing explanation

Fig. 2 is the A direction view of Fig. 1.
Fig. 3 is the scheme of installation of small worm in Fig. 2.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Fig. 1,2 and 3, a kind of Dual Drive gear hobbing machine worktable, indexing worm 1 is by bearings on workbench housing 2, and the input of this indexing worm is coaxially connected with servomotor 3 output shaft on workbench housing 2.Dividing worm wheel 4 often engages with indexing worm 1, and is solidly set on work top 5, and this work top is rotatably supported on workbench housing 2.The first bevel gear 6 on indexing worm 1 often engages with the second bevel gear 7, and this second bevel gear 7 and the 3rd bevel gear 8 are solidly set on transition axis 9 two ends, and transition axis by bearings on workbench housing 2.3rd bevel gear 8 often engages with the 4th bevel gear 11 on damping worm screw 10, and this damping worm screw 10 is by bearings on workbench housing 2, and damping worm screw 10 is parallel with indexing worm 1, and often engages with dividing worm wheel 4.
Work top 5 below dividing worm wheel 4 is installed with a small gear 12, this small gear often engages with small worm 13, and small worm by bearings on workbench housing 2, and the input of small worm is coaxially connected with the output of drive motors 14.
The foregoing is only preferred embodiment of the present invention, is not restriction with the present invention, and all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
