FIG. 1 is a partial cross-sectional view of a helical gear outer ring gear correction device according to an embodiment of the present utility model; FIG. 2 is a schematic cross-sectional view of the helical gear outer ring gear correcting device of FIG. 1 taken along the line A-A in a corrected state when a workpiece is loaded.
Detailed Description
In order to further understand the technical scheme of the utility model, the technical scheme of the utility model is clearly and completely described by the embodiment and the attached drawings.
As shown in fig. 1-2. The correcting device for the helical gear outer gear ring comprises a module 3, a positioning plate 6, a baffle plate 2, a bottom plate 1, a positioning seat 5, a positioning key groove device and the like, wherein the bottom plate 1 and the positioning seat 5 are respectively arranged on two opposite sides of the module 3.
The module 3 is provided with an assembly correction hole 10, and the outer peripheral wall, the inner diameter and the like of the assembly correction hole 10 are correspondingly matched with the corrected workpiece, the outer gear ring and the like, and in the embodiment, the workpiece is a bevel gear. The module 3 and its assembly correction hole 10 may be formed by symmetrical half-module bodies, the bottom plate 1 is fixedly connected to the side wall of half-module body 3a of the module 3 corresponding to the workbench or press workbench, the positioning seat 5 is fixedly connected to the corresponding side wall of the other half-module body 3b of the module 3 by corresponding fastening screw 7, and the positioning plate 6 is fixedly connected to the positioning seat 5 by screw 7.
The bottom plate and the two half-mould blocks of the module 3 form a correction frame, the correction frame can be cut off from the center by linear cutting after being integrally processed, and assembly correction holes consistent with the outer circle of a workpiece can be formed after the two half-mould blocks are combined.
The positioning key groove device comprises a positioning key groove 4a arranged on the outer wall surface of the bottom plate 1, a corresponding positioning key groove 4b arranged on the press bench 11 and a positioning key 8, wherein the positioning key 8 can be correspondingly connected with the corresponding positioning key grooves of the bottom plate and the press bench at the same time.
The baffle plate 2 is correspondingly positioned on the corresponding side surface of the module 3 and the helical gear 9 in the axial direction and is fixedly connected with one half of the module body 3a of the module through corresponding screws, and the helical gear 9 placed in the module can be limited through the baffle plate 2.
When the machine tool is in operation, the other half module body 3b of the module 3 and the positioning seat 5 thereof are connected with a machine tool spindle through the positioning plate 6, the bottom plate of the half module body 3a of the module is arranged on a press working table through the bottom plate 1, and is positioned on the press working table through positioning keys through the bottom plate and positioning key grooves of the press working table, and meanwhile, the bottom plate 1 fixes the half module body 3a of the module on the press working table through corresponding fastening screws; the bevel gear is placed on one half of the module body 3a and is attached to the flat positioning surface, the baffle plate 2 is used for limiting and positioning the correction hole of the half of the module body 3a on the axial side of the bevel gear, at the moment, the machine tool handle is positioned at a corresponding position, the other half of the module body 3b is suspended above the half of the module body 3a and the bevel gear, and when the machine tool handle is pressed down, the other half of the module body 3b of the module body 3 moves towards the half of the module body 3a, so that the two half of the module body 3a tends to be folded, and the deformed part bevel gear is corrected into an accurate circle. After correction, the machine tool handle is loosened to the original corresponding position, and the bevel gear is taken out from the half module body 3a of the module.
