Abstract
This utility model provides a kind of gear hobbing tooling, including pedestal, pedestal has gear hob mandrel and top rod, and gear hob mandrel includes that plug body, one end of plug body are lathe clamping part；The other end of plug body is gear ring clamping part, and the top of described gear ring clamping part has blind hole, and the perisporium of described blind hole has the open slot of more than 2.Have the advantages that working (machining) efficiency is high, machining accuracy is high.
Description
Technical field
This utility model relates to gear mechanism manufacture field, and specifically, this utility model relates to the gear hobbing tooling of a kind of gear.
Background technology
When gear carries out gear hobbing work, gear hobbing tooling plays the most crucial effect, and its quality used directly affects quality and the working (machining) efficiency of Gear Processing.
Existing gear teeth frock, its gear hob mandrel is all that employing is threaded in clamping gear ring one end, gear ring is namely sleeved on one end of plug, is processed (such as Chinese patent CN 203418182 U) after then being tightened by the external screw thread on nut and plug；Such frock not only loads and unloads inconvenience, and working (machining) efficiency is low, and it cannot be guaranteed that the concentricity of product, machining accuracy is low.
Summary of the invention
In order to solve problem of the prior art, this utility model provides the gear hobbing tooling that a kind of working (machining) efficiency is high, machining accuracy is high.
This utility model provides a kind of gear hobbing tooling, including pedestal, pedestal has gear hob mandrel and top rod, and gear hob mandrel includes that plug body, one end of plug body are lathe clamping part；The other end of plug body is gear ring clamping part, and the top of described gear ring clamping part has blind hole, and four perisporiums of described blind hole have the open slot of more than 2.
Further, the front end of described blind hole has a chamfering, and one end of top rod has suitable with chamfering top.
Further, the perisporium of described blind hole is uniform has 3 open slots.
The technical scheme that this utility model provides has the benefit that the gear hobbing tooling that this utility model provides, in use, have only to be sleeved on plug gear ring, effect due to open slot, make gear hob mandrel front end form a three-pawl type, held out against by top rod, can simultaneously work as clamping gear ring and ensureing the purpose of gear ring concentricity, both improve working (machining) efficiency, improve again machining accuracy.
Accompanying drawing explanation
For the technical scheme being illustrated more clearly that in the present invention, in describing embodiment below, the required accompanying drawing used is briefly described, apparently, accompanying drawing in describing below is only some embodiments of this practicality, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the schematic side view of this utility model gear hob mandrel one end.
Detailed description of the invention
For making content of the present utility model more clear understandable, below in conjunction with Figure of description, content of the present utility model is described further.Certainly this utility model is not limited to this specific embodiment, and general replacement the known to those skilled in the art is also covered by within the scope of the present invention.Secondly, this utility model utilizes schematic diagram to carry out detailed statement, and when describing this utility model example in detail, for convenience of description, schematic diagram, not according to general ratio partial enlargement, should not limit in this, as to this utility model.
As shown in Figure 1, 2, this utility model provides a kind of gear hobbing tooling, including pedestal 1, pedestal 1 has gear hob mandrel 2 and top rod 3, and gear hob mandrel 2 includes that plug body 2-1, one end of plug body 2-1 are lathe clamping part 2-2；The other end of plug body 2-1 is gear ring clamping part 2-3, and the top of described gear ring clamping part 2-3 has blind hole 2-3-1, and four perisporiums of described blind hole 2-3-1 have the open slot 2-3-2 of more than 2.
The front end of described blind hole 2-3-1 has chamfering 2-3-3, and one end of top rod 3 has the top 3-1 suitable with chamfering 2-3-3.The advance and retreat of top 3-1 can be more beneficial for.
The perisporium of described blind hole 2-3-1 is uniform has 3 open slot 2-3-2.This utility model can certainly use 4,6, the form such as 8 open slot 2-3-2, to meet the supporting of different-diameter gear ring.
