Background technology
Bevel gear built in auto gearbox is a kind of transmission parts for being directly used in transfer of torque, its crudy
Directly affect vehicle vibration and noise specification.Because driving comfort can be the important performance assessment criteria of examination car, therefore to automatic
The supporting transmission parts quality of speed changer has very strict quality requirement.The supporting bevel gear of auto gearbox is in pipe sleeve
Structure, and one end is provided with outer cone tooth, endoporus is provided with internal spline, its cylindrical relative outer cone tooth and internal spline have relative size,
Shape and required precision, far design requirement is not reached with the dabber clamp processing of routine.
The content of the invention
The problem of can not meeting the requirement of bevel gear smart car present invention is generally directed to the dabber clamp positioning precision of prior art,
It is proposed a kind of simple in construction, install convenient, the bevel gear excircle finish turning fixture of accurate positioning.
The present invention is achieved through the following technical solutions technical goal.
Bevel gear excircle finish turning fixture, it is collectively constituted by mandrel, locating ring, pedestal, steel ball, pin, bushing and nut.
The mandrel is the cylinder axis that both ends are all provided with centre bore, and an end ring outer wall is sequentially provided with the radial direction platform that twice size does not wait
Shoulder, the small size radial direction shoulder positioned at inner side are used for location and installation pedestal.Another end head of mandrel is set with bushing and provided with installation
The external screw thread of nut, after workpiece is inserted in mandrel, tightening nut is formed to workpiece axial locking structure.It is theed improvement is that：Institute
It is annular component to state locating ring, and endoporus is provided with workpiece identical internal spline, the locating ring axial direction stop bit being sleeved on mandrel
In inner side small size radial direction shoulder, at least 4 cylindrical pins are uniformly assigned in locating ring internal spline teeth groove, it is remaining exposed
Pin is inserted in the internal spline tooth socket fit of workpiece with after, and this structure directly constitutes the radial positioning on the basis of internal spline.It is described
Pedestal is the axially position seat being engaged with mandrel, and the end face for facing workpiece is provided with counterbore, and counter bore hole diameters bore increment than workpiece
Big 3.0~the 5.0mm of maximum outside diameter, along the uniform steel ball that at least 3 positions are fixed in counterbore side, workpiece is formed to bore the flank of tooth and steel ball
The axial positioning structure of cooperation.
As further improvement project, the pin is elongated rod member, after insertion respectively with internal spline teeth groove both sides
The flank of tooth is tangent, also cylindrical tangent with mandrel.
As further improvement project, the steel ball size is chosen between φ 6mm~φ 12mm.
The present invention compared with prior art, has the positive effect that：
1st, simple in construction, workpiece install convenient axially is inserted in, clamping is reliable；
2nd, workpiece radially and is axially implementing external cutting processing under location condition, smart car steady quality, and precision is secure；
3rd, accessible cutting, production efficiency are high.
Brief description of the drawings
Fig. 1 is structural profile illustration of the present invention.
Fig. 2 is Figure 1A-A places section enlarged diagram.
Embodiment
Below according to accompanying drawing and in conjunction with the embodiments, the invention will be further described.
Bevel gear excircle finish turning fixture shown in Fig. 1, it is by mandrel 1, locating ring 2, pedestal 3, steel ball 4, pin 5, bushing 6
Collectively constituted with nut 7.The mandrel 1 is the main component of fixture, and both ends are equipped with the centre bore for positioning support.Mandrel 1
The outer wall of close lathe bare terminal end is sequentially provided with the radial direction shoulder that twice size does not wait, the small size positioned at the side of workpiece 8
Radial direction shoulder is used for location and installation pedestal 3.The other end of mandrel 1 is set with bushing 6 and installs the external screw thread of nut 7, treats that workpiece 8 is inserted in
After mandrel 1, tightening nut 7 is formed to the axial locking structure of workpiece 8.The locating ring 2 is annular component, and endoporus is provided with and work
The identical internal spline of part 8, the 2 axial stop bit of locating ring on mandrel 1 is sleeved in inner side small size radial direction shoulder, in locating ring 2
At least 4 cylindrical pins 5 are uniformly assigned in internal spline teeth groove, the present embodiment is because specification is relatively small, therefore in locating ring 2
4 pins 5 as shown in Figure 2 are uniformly assigned in spline teeth groove.In the pin 5 exposed outside of locating ring 2 workpiece 8 is inserted in after
Internal spline tooth socket fit, this structure directly constitute radial positioning of the workpiece 8 on the basis of internal spline.The pedestal 3 is and mandrel 1
The axially position seat being engaged, the end face for facing workpiece 8 are provided with counterbore, and counter bore hole diameters are bigger than the bevel gear maximum outside diameter of workpiece 8
3.0mm.In order to improve the axially position precision of pedestal 3 and workpiece 8, steel that the present invention fixes along uniform 3 positions in counterbore side
Ball 4, workpiece 8 is thus formed to bore the axial positioning structure that the flank of tooth coordinates with steel ball 4.
Said structure belongs to mandrel class fixture, simple and reasonable for structure, and the install convenient of workpiece 8, clamping is reliable, is installed in place
Workpiece 8 stablized, be reliable, accurate radial positioning and axially position, along with the outer wall of workpiece 8 is exposed, in this condition
Under accessible cutting, in addition to production efficiency is high, more importantly outer circle finish turning quality is good and stably.
