Further, first coarse adjustment movable stand extended position in described step (2), then the extension elongation of accurate adjustment telescoping mechanism, make approach switch and datum mark at a distance of 1-2mm.
Further, PLC controller control workbench clockwise or be rotated counterclockwise 180 °/Z (Z is the gear number of teeth), is found on this gear and the reference point location corresponding to gear mechanism in described step (3).
Beneficial effect of the present invention is: this apparatus structure is simple, method of operating is simple and easy to do, by add to gear mechanism record first gear to dentation state,, as long as ensure the validity that aligns first, follow-up gear can be found accurately automatically, without again manually aligning, reduce human error, and taking same state as benchmark, high conformity, precision is high, is particularly suitable for batch machining; Meanwhile, because of hobboing cutter surplus distributed uniform, be also greatly improved the service life of hobboing cutter.
Brief description of the drawings
In order to make object of the present invention, technical scheme and beneficial effect clearer, the invention provides following accompanying drawing and describe:
Fig. 1 is that the present invention is installed on the structural representation on gear-hobbing machine;
Fig. 2 is front view of the present invention
Fig. 3 is the top view of Fig. 2.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
As shown in the figure, large-scale gear hobbing machine of the present invention is automatically to gear mechanism, comprise and can carry out support 1, telescoping mechanism 2 and the PLC controller that height regulates along Y direction, described telescoping mechanism 2 is provided with movable stand 3 and approach switch 4, described movable stand 3 is slidably matched along X-direction with described support 1, and described PLC controller is arranged on gear-hobbing machine and with telescoping mechanism 2 and approach switch 4 and is connected.
In the present embodiment, support 1 is fixed on a side of gear hobbing machine worktable 5, and near gear to be processed, support 1 upper end is provided with rail groove, on movable stand 3, correspondence is provided with the track matching with rail groove, and telescoping mechanism 2 is pneumatic cylinder, and movable stand 3 is sleeved on pneumatic cylinder and with it and forms a whole, in the time regulating the position, left and right of movable stand 3 along X-direction, pneumatic cylinder moves left and right with movable stand 3; Piston rod on pneumatic cylinder also can stretch separately, can realize the position adjustments of approach switch 4 in X-direction by pneumatic cylinder upper piston rod and/or movable stand 3.
As the further improvement of such scheme, described support 1 is provided with many groups for locking the clamping screw 6 of movable stand 3, and the location of realizing movable stand 3, prevents its play.
As the further improvement of such scheme, described support 1 is provided with limiting plate 7, the maximum amount of movement of movable stand 3 is carried out spacing, can effectively prevent the problem that causes track and rail groove mutually to depart from because regulated quantity is excessive.
Utilize and above-mentioned gear mechanism carried out to the gear-hobbing machine method to tooth automatically, mainly comprise the following steps:
