The following is further detailed by way of specific embodiments:
reference numerals in the drawings of the specification include: the device comprises a hobbing base 1, a thimble seat 2, a support seat 3, a thimble 4, a chuck 5, a chuck pressing block 6, a bolt I7, a support 8, an installation block 9, a locking screw 10, a threaded through hole I11, a chuck positioning block 12, a bolt II 13, a holding screw 14, a pin shaft 15, a limiting ring 16, a string 17 and a shaft 18.
Example one
This embodiment is substantially as shown in fig. 1 and 2: the universal fixture for the gear hobbing comprises a hobbing base 1, wherein an ejector pin base 2 and a support base 3 are fixedly mounted on the hobbing base 1. The thimble 4 is fixedly installed on the thimble seat 2, and in this embodiment, the thimble seat 2 has been seted up the installation deep hole, and thimble 4 and installation deep hole interference fit. And a chuck 5 and a chuck pressing block 6 are arranged above the thimble 4, the upper end of the chuck 5 is hinged with the lower end of the chuck pressing block 6, the upper end of the chuck 5 and the upper end of the chuck pressing block 6 are both provided with through holes, the chuck 5 is aligned with the through holes of the chuck pressing block 6, and a bolt I7 penetrates through the through holes.
The support base 3 is fixedly provided with a support 8, specifically, the bottom end of the support 8 is integrally formed with a mounting block 9, at least four threaded through holes IV are formed in the circumferential direction of the mounting block 9, threaded through holes V corresponding to the threaded through holes IV one to one are formed in the top end of the support base 3, and the threaded through holes IV and the threaded through holes V are jointly in threaded connection with a locking screw 10. In this embodiment, the number of the threaded through holes iv and the threaded through holes v is four, and the four threaded through holes iv are distributed at four corners of the mounting block 9. A spring washer (not shown) is provided between the locking screw 10 and the mounting block 9.
Set up the screw thread through-hole I11 of a plurality of vertical arrangements on the support 8, in this embodiment, the quantity of screw thread through-hole I11 is three. The middle part fixedly connected with chuck locating piece 12 of chuck 5, chuck locating piece 12 crooked setting, threaded through hole II has been seted up to the bottom of chuck locating piece 12, and threaded through hole II aligns and common threaded connection has bolt II 13 with threaded through hole I11 at support 8 top.
During the use, rotate bolt I7, release chuck 5 and chuck briquetting 6's upper end, rotate chuck briquetting 6, will treat the vertical top of putting in thimble 4 of processing axle 18, then, rotate chuck briquetting 6 for the upper end of chuck briquetting 6 is close to the lower extreme of chuck 5 again, utilizes bolt I7 locking chuck 5 and chuck briquetting 6's upper end, thereby realizes treating the clamp of processing axle 18 and tightly, can carry out the gear hobbing next. And after the gear hobbing is finished, rotating the bolt I7, rotating the chuck pressing block 6, and taking down the shaft 18.
If hobbing of different types of shafts is required next, the connecting position of the chuck positioning block 12 and the bracket 8 is adjusted according to the shape of the shaft, so that the height positions of the chuck 5 and the chuck pressing block 6 are changed, and the chuck 5 and the chuck pressing block 6 can clamp and clamp the shaft 18. For example, when the connecting position of the chuck positioning block 12 and the bracket 8 is not changed, the chuck 5 and the chuck pressing block 6 can only clamp the middle part of the shaft, but the diameter of the middle part of the shaft is larger than the range capable of clamping the chuck 5 and the chuck pressing block 6, and the shaft cannot be clamped. Then, the height positions of the chuck 5 and the chuck pressing block 6 are lowered by adjusting the connecting position of the chuck positioning block 12 and the bracket 8, so that the chuck 5 and the chuck pressing block 6 can clamp the part with the smaller diameter of the shaft, and the shaft is clamped.
