The utility model discloses a kind of roller gear roll flute positioning tool, its agent structure includes：Mandrel, spline housing, transition sleeve and nut, the mandrel is provided with lathe connecting portion, stage portion, gear location division and the nut connecting portion being sequentially connected, the spline housing is set on the outside of gear location division, the nut is arranged on nut connecting portion, the transition sleeve both ends are respectively sleeved on the outside of spline housing and nut, and transition sleeve both ends are connected with spline housing and nut respectively.The utility model, as positioning datum, can more reach the precision required by drawing using the big footpath of spline in accuracy of detection；And by the improvement in connected mode, frock is more convenient when taking workpiece；The problem of conical surface contact manner of spline housing inwall and mandrel outer wall, realizing and the more press the more tight and technique effect that stability is high, and be not in the phenomenon that pressure rebounds partially, thus the conical surface caused by without worrying long-time use wears, and then causing prestressing force deficiency.
Description
Technical field
Gear machining technology field is the utility model is related to, more particularly to a kind of roller gear roll flute positioning tool.
Background technology
During roller gear roll flute used positioning tool be generally all by the use of spline path as positioning datum, it is this fixed
Position mode is frequently encountered a problem：Workpiece sensing precision does not often reach drawing requirement, and such frock fit clearance
Big workpiece uniformity and stability are poor.
The main reason for causing above mentioned problem be：The spline path of roller gear is that lathe process is formed, and cylinder
Gear is needed by carburizing and quenching, and the spline path after being heat-treated can produce larger deflection, so as to have impact on
The positioning precision of frock.
And the big footpath of spline is molded by spline broach wire pulling method, therefore the precision in the big footpath of spline and uniformity are higher,
After carburizing and quenching, the big footpath of spline is much smaller compared with spline path heat treatment deformation, therefore uses the big footpath conduct of spline
Positioning datum, precision of grinding teeth are much higher with respect to spline path positioning precision of grinding teeth.
Utility model content
It is big using spline the utility model discloses one kind to solve the problems, such as existing roller gear roll flute positioning precision difference
Roller gear roll flute positioning tool of the footpath as positioning datum, its agent structure include：
Mandrel, spline housing, transition sleeve and nut, the mandrel are provided with lathe connecting portion, stage portion, the tooth being sequentially connected
Location division and nut connecting portion are taken turns, the spline housing is set on the outside of gear location division, and the nut is arranged on nut connection
In portion, the transition sleeve both ends are respectively sleeved on the outside of spline housing and nut, and transition sleeve both ends respectively with spline housing and spiral shell
Mother's connection.
As the further improvement of above-mentioned technical proposal, the gear location division is circular cone structure, and the spline is arranged
There is the conical wall coordinated with gear location division.
As the further improvement of above-mentioned technical proposal, the spline housing outer wall is provided with some and gear along its circumferencial direction
The key teeth of spline fitted.
As the further improvement of above-mentioned technical proposal, the spline housing top is provided with the first flange, the nut bottom
Provided with the second flange, the first snap ring and the second snap ring of protrusion are respectively equipped with the inwall at the transition sleeve both ends, described first
Snap ring and the first flange clamping, second snap ring and the second flange clamping.
The beneficial effects of the utility model are：
The gear grinding tooling positioned relative to spline path, the utility model, as positioning datum, are being examined using the big footpath of spline
The precision required by drawing can more be reached in survey precision；And by the improvement in connected mode, frock when taking workpiece more
Add convenient and swift；The conical surface contact manner of spline housing inwall and mandrel outer wall, realize and the more press the more tight and technology that stability is high
Effect, and be not in the phenomenon that pressure rebounds partially, thus the conical surface caused by without worrying long-time use wears, and then cause
The problem of prestressing force deficiency.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.
As shown in figure 1, the roller gear roll flute positioning tool of the present embodiment, its agent structure include：Mandrel 1, spline housing
2nd, transition sleeve 3 and nut 4.
Mandrel 1 is provided with lathe connecting portion 11, stage portion 12, gear location division 13 and the nut 14 being sequentially connected and connected
Portion.
Gear location division 13 is circular cone structure, and spline housing 2 is provided with the conical wall coordinated with gear location division 13, flower
Key covers 2 outer walls and is provided with some key teeths 22 coordinated with gear spline along its circumferencial direction.
Spline housing 2 is set in the outside of gear location division 13, the taper-face contact of the inwall of spline housing 2 and the outer wall of gear location division 13
Mode, realize and the more press the more tight and technique effect that stability is high, and be not in the phenomenon that pressure rebounds partially, thus without load
The conical surface caused by heart long-time use wears, and then the problem of cause prestressing force deficiency.
Nut 4 is arranged on nut connecting portion 14, and the both ends of transition sleeve 3 are respectively sleeved at the outside of spline housing 2 and nut 4.
As shown in Fig. 2 the top of spline housing 2 is provided with the first flange 21, the bottom of nut 4 is provided with the second flange 41,3 liang of transition sleeve
The first snap ring 31 and the second snap ring 32 of protrusion, the first snap ring 31 and the clamping of the first flange 21 are respectively equipped with the inwall at end, the
Two snap rings 32 and the clamping of the second flange 41.Pulling force is transmitted to spline housing 2 by transition sleeve 3 when nut 4 rotates, it is convenient to take workpiece
Fast.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc., the utility model should be included in
Protection domain within.
