Abstract

The utility model relates to the technical field of gear machining and manufacturing, and discloses a gear tool structure of a gear hobbing machine. The gear tool structure aims to solve the problems that as a gear in the prior art is not reasonable in work structure, the gear bears pressure to deform easily, and hobbing accuracy is relatively low. The gear tool structure comprises a hub cushion block and a flange cushion block used for supporting the flange of a gear, wherein the hub cushion block is used for supporting a hub of the gear, and the hub cushion block and the flange cushion block are fixedly connected with a workbench of the gear hobbing machine respectively; the upper portion of the gear is further provided with a gear pressing board in a pressing mode, one end of the gear pressing board is supported on the flange of the gear, the other end of the gear pressing board is supported on the flange cushion block through a supporting screw rod penetrating through a gear lightening hole, and the supporting screw rod is in thread connection with the gear pressing board; the gear pressing board is provided with a kidney-shaped hole, a tensioning screw rod longitudinally penetrates through the kidney-shaped hole, the upper end of the tensioning screw rod is located on the upper portion of the gear pressing board and is provided with a locking nut, the lower end of the tensioning screw rod penetrates through the gear lightening hole and is fixedly connected with the flange cushion block. The gear tool structure can effectively prevent the gear from distortion and deformation and improve hubbing accuracy.

Description

A kind of gear tool structure of gear-hobbing machine
Technical field
The utility model relates to a kind of tool structure, and particularly a kind of gear tool structure of gear-hobbing machine, belongs to Gear Processing manufacturing technology field.
Background technology
In prior art, the gear tool structure that has a kind of gear-hobbing machine, comprise gear hobbing machine worktable, gear to be processed and supplemental support top, the centre bore of gear to be processed is penetrated with pull bar, gear to be processed press-fits on gear hobbing machine worktable by pull bar, and supplemental support top is supported on the wheel rim of gear to be processed lower surface.
Its weak point is: because the wheel rim of gear to be processed bears supplemental support top support force upwards, and the wheel hub of gear to be processed bears downward pulling force, make that strength of gear to be processed is unbalanced to be caused, easily cause gear torsional deformation to be processed, affect gear hobbing precision.
Utility model content
The purpose of this utility model is for deficiency of the prior art, and a kind of gear tool structure of gear-hobbing machine is provided, and has solved in prior art because working gear unreasonable structure causes the problem that strength of gear is yielding, gear hobbing precision is lower.
The purpose of this utility model is achieved in that a kind of gear tool structure of gear-hobbing machine, comprise that described wheel hub cushion block is fixedly connected with the workbench of gear-hobbing machine respectively with wheel rim cushion block for the wheel hub cushion block of Support Gear wheel hub with for the wheel rim cushion block of Support Gear wheel rim; Gear top has also been installed with gear pressing plate, and one end of described gear pressing plate is supported on the rim of gear, and the other end is supported on described wheel rim cushion block by running through the studdle of gear lightening hole, and described studdle is threaded with gear pressing plate; On described gear pressing plate, offer mounting hole, described mounting hole is longitudinally penetrated with stretching screw, the upper end of stretching screw the top that is positioned at described gear pressing plate are installed with locking nut, and the lower end of stretching screw is fixedly connected with wheel rim cushion block through described gear lightening hole.
During the utility model work, gear is placed on the working face being formed by wheel hub cushion block and wheel rim cushion block, after centering top circle, the free end that is rotary with the gear pressing plate of studdle is placed on the wheel rim of gear, rotary support screw rod makes the lower working face of gear pressing plate and the wheel rim of gear substantially in same plane, then the lower end of stretching screw is inserted to the mounting hole of gear pressing plate, run through by after gear lightening hole, be fixedly connected with wheel rim cushion block, the upper end of stretching screw screws on locking nut, coordinate and regulate studdle, make gear pressing plate compress gear.Compared with prior art, the beneficial effects of the utility model are: gear hub is supported by wheel hub cushion block, and the rim of gear coordinates wheel rim cushion block upper-lower compacting by gear pressing plate, realizes rim of gear producing balanced forces, effectively avoids gear torsional deformation, has improved gear hobbing precision.
Described wheel rim cushion block includes the connecting plate being wholely set with wheel rim cushion block, on described connecting plate, offers through hole, is provided with T-shaped nut in through hole, and the lower end of described stretching screw is connected with T-shaped nut thread through through hole.Stretching screw is connected with wheel rim cushion block by T-shaped nut, makes dismounting more convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1, gear; 1a, the rim of gear; 1b, gear hub; 1c, gear lightening hole; 2, wheel hub cushion block; 3, wheel rim cushion block; 3a, connecting plate; 4, workbench; 5, gear pressing plate; 5a, mounting hole; 6, studdle; 7, stretching screw; 8, locking nut; 9, T-nut.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of gear tool structure of gear-hobbing machine, comprises that wheel hub cushion block 2 is fixedly connected with the workbench 4 of gear-hobbing machine respectively with wheel rim cushion block 3 for the wheel hub cushion block 2 of Support Gear wheel hub 1b with for the wheel rim cushion block 3 of Support Gear wheel rim 1a; Gear 1 top has also been installed with gear pressing plate 5, and it is upper that one end of gear pressing plate 5 is supported on rim of gear 1a, and the other end is supported on wheel rim cushion block 3 by running through the studdle 6 of gear lightening hole 1c, and studdle 6 is threaded with gear pressing plate 5; On gear pressing plate 5, offer mounting hole 5a, mounting hole 5a is longitudinally penetrated with stretching screw 7, and the upper end of stretching screw 7 top that is positioned at gear pressing plate 5 are installed with locking nut 8, and the lower end of stretching screw 7 is fixedly connected with wheel rim cushion block 3 through gear lightening hole 1c.
For ease of dismounting, wheel rim cushion block 3 includes the connecting plate 3a being wholely set with wheel rim cushion block 3, on connecting plate 3a, offers through hole, is provided with T-shaped nut 9 in through hole, and the lower end of stretching screw 7 is threaded with T-shaped nut 9 through through hole.
The utility model is not limited to above-described embodiment; on the basis of the disclosed technical scheme of the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in protection domain of the present utility model.
