According to the utility model, a common lathe can be used for machining the high-precision lug boss of the planet carrier gear to achieve dimensional precision and position precision, so that the production cost is saved for enterprises, the technical requirements of parts are met, a technical device is convenient and reliable in clamping and stable in machining quality, and a better reference role is played for further innovation of machining of the similar planet carrier gears in future.
Description
Technical field
the utility model relates to a kind of positioner with machined into planet carrier gear boss, belongs to the processing field of locating technology of polymorphic structure.
Background technology
are present, planet carrier gear of a great variety, and its processing method also is varied.The planet carrier gear is the fixing support rack in the epicyclic transmission mechanism.Be to guarantee sun gear and planetary gear correct engagement in the Gear Planet Transmission, the centre-to-centre spacing between each meshing gear must equate, so the relative position of boss deviation of centre distance, dimensional accuracy and the planetary gear of planet carrier gear is had higher requirement.It is a very important member, in its Gear Planet Transmission, has a very important role.High more to the epicyclic transmission mechanism required precision simultaneously, also just high more to the required precision of planet carrier gear.The relative position of boss deviation of centre distance, dimensional accuracy and planetary gear is the emphasis and the difficult point of processing.The processing method of planet carrier gear boss mainly contains two kinds at present: the one, adopt Milling Process on the plain-milling machine, and the 2nd, carry out Milling Process through machining center.During Milling Process, the size of boss, positional precision all can't meet the demands on plain-milling machine.When adopting machining center to carry out Milling Process, though the positional precision of planetary gear boss can meet the demands, dimensional accuracy is difficult to guarantee.
Summary of the invention
The purpose of
the utility model is, a kind of positioner with machined into planet carrier gear boss is provided.Can utilize engine lathe that planet carrier gear boss is carried out high-precision processing, simple in structure, accurate positioning, easy to use can improve machining accuracy and processing efficient, saves production cost, thereby overcomes the deficiency of present technology.
The technical scheme of the utility model
a kind of positioner with machined into planet carrier gear boss, positioner is the cylinder table scalariform, positioner is provided with locating surface; Locating surface is provided with locating hole, dowel hole and pressing plate, and the pressing plate warp is connected with screwed hole on the locating surface.
In
aforementioned positioner with machined into planet carrier gear boss, the centre-to-centre spacing of said locating hole and positioner equals the boss center of planet carrier gear and the distance of planet carrier central gear axis.
In
aforementioned positioner with machined into planet carrier gear boss, it is H6/h5 that said locating hole cooperates with the location cylindrical of planet carrier gear.
compared with prior art; Can utilize engine lathe processing planet carrier gear boss dimensional accuracy, positional precision height through the utility model; Enhance productivity, save production cost, reached the part specification requirement again, the technological equipment convenient mounting and clamping is reliable; Stable processing quality has reference function preferably to the further innovation of the processing of similar planet carrier gear from now on.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the planet carrier gear sketch map to be processed of the utility model;
Fig. 3 is the working state schematic representation of the utility model;
Being labeled as in
accompanying drawing: 1-positioner, 2-locating surface, 3-locating hole, 4-dowel hole, 5-screw, 6-pressing plate, 7-alignment pin, 8-planet carrier gear, 9-boss, 10-central shaft, 11-datum level, 12-fabrication hole.
The specific embodiment
are further described the utility model below in conjunction with accompanying drawing and embodiment, but not as the foundation to the utility model restriction.
embodiment.A kind of positioner with machined into planet carrier gear boss, shown in figure one, positioner 1 is the cylinder table scalariform, positioner 1 is provided with locating surface 2; Locating surface 2 is provided with locating hole 3, dowel hole 4 and pressing plate 6, pressing plate 6 through 5 with locating surface 2 on screwed hole be connected.Said locating hole 3 equals the boss center of planet carrier gear and the distance of planet carrier central gear axis 10 with the centre-to-centre spacing of positioner 1.It is H6/h5 that said locating hole 3 cooperates with the central shaft 10 of planet carrier gear.
The practical implementation process of the utility model:
are following to be that example specifies the process of the utility model with machined into of using with the planet carrier gear shown in the figure two.Adding man-hour serves as the location cylindrical with the central shaft 10 of planet carrier gear, is datum level 11 with the baseplane of planet carrier gear, with the fabrication hole 12 of planet carrier gear as index hole.
During
concrete operations; Press shown in the figure three: the central shaft on the planet carrier gear 8 10 is inserted in the locating hole 3 of positioner 1; And with on the datum level on the planet carrier gear 8 11 locating surface that leans against positioner 12 tightly; Rotate planet carrier gear 8 then, one of them fabrication hole 12 that passes the planet carrier gear with alignment pin 7 inserts in the dowel hole of positioners 1 to confirm the orientation of planet carrier gear.Confirm to load onto pressing plate 6 behind the tram of planet carrier gear 8,, carry out the processing of first boss 9 screw 5 lockings.The processing of all the other boss as long as extract alignment pin 7, lets planet carrier gear 8 rotate suitable angle around locating hole 3 centers, and alignment pin 7 gets in next fabrication hole 12, processes other boss so successively.Guarantee boss shaft size and position accuracy demand.
Annotate
: the part in part process hole is cut off after 3 boss completion of processing.
The eccentric value of
fabrication hole 12 is 1/2 of a planet carrier gear boss centre-to-centre spacing, and precision is chosen and should be able to be satisfied instructions for use.The center of the utility model positioner should be consistent with the lathe for machining chuck hub.
The utility model guarantees machining accuracy in the following manner:
1, selection fine finishining positioning reference in conjunction with processing request, are followed the unifying datum principle.The relative tooth reference circle of the center line of 3 boss 9 on the planet carrier gear 8 has higher position degree requirement, should select to add the same benchmark of using man-hour (central shaft 10 on the planet carrier gear 8) with the tooth reference circle during processing boss 9.Thereby the assurance unifying datum, the location cylindrical 10 on the planet carrier gear 8 can adopt H6/h5 with cooperating of the locating hole 3 of the utility model.
2, be convenient location; The utility model has adopted the principle of " benchmark of doing for oneself "; Shown in figure one: the free degree of coming the alignment restrictions direction of rotation with manufactured 3 fabrication holes on the planet carrier gear 8; Dowel hole 4 on the positioner 1 and fabrication hole 12 dimensional accuracies on the planet carrier gear 8 are selected consistent, alignment pin and optional H6/h5 of cooperating of they.
3, clamping are simply rapidly, and be efficient and convenient.The 6 pairs of parts of screw 5, pressing plate that directly are employed on the utility model positioner like figure three compress.
