Abstract
The invention discloses a planet carrier inspection device for a tractor. The planet carrier inspection device is mainly composed of a deflection instrument, a nut, a gasket, a planet carrier, a grouping spindle, a spline shaft and a taper shaft; the planet carrier is the spare part to be inspected, the grouping spindle is fixed in an unthreaded hole of the planet carrier, the spline shaft with external splines is assembled at internal splines of the planet carrier, the taper shaft with taper is completely matched with the spline shaft so as to support the spline shaft in the internal splines of the planet carrier and prevent the planet carrier from shaking on the spline shaft, the adaptability degree between the taper shaft and the spline shaft is improved through using the nut and gasket, the taper shaft is jacked up by the deflection instrument through central holes at two ends of the taper shaft, when inspecting, the planet carrier is rotated to inspect the internal splines of the planet rack and the other sizes and location degrees. The planet carrier inspection device for the tractor is featured with high accuracy and high inspection efficiency.
Description
Technical field
Originally relate to a kind of cubing of tractor with profit, be used in particular for a kind of cubing for detection of planet carrier in tractor.
Background technology
The measurement cubing of the planet carrier band female spline of current tractor, major part all adopt the interrod spacing of length bar measure spline processing whether meet Design Requirement Drawing, and planet carrier spline and his status requirement of drawing tool and dimensional requirement all cannot detect, cannot measure and whether meet Design Requirement Drawing.Especially in planet carrier three fill position relationship between planetary hole and female spline and the dimensional tolerence in these three holes self is also to measure.Cause can only be assembled into assembly and rotate and find whether to have abnormal, if any extremely, need to pull down part and ressemble combination; This result causes work efficiency low, to organization of production, causes great difficulty.
Summary of the invention
The object of this patent is: provide one to be used in the cubing that detects planet carrier in tractor, can effectively before assembling, to planet carrier, detect, economize on resources, raise labour efficiency, reduce production assembly cost.
The technical solution of this patent is: a kind of planet carrier cubing of tractor, is mainly comprised of deflection instrument, nut, packing ring, planet carrier, grouping mandrel, splined shaft and taper shaft; Planet carrier is tested part, grouping mandrel is fixed in the unthreaded hole of planet carrier, splined shaft with male splines is assemblied in planet carrier female spline place, taper shaft with tapering is coordinated mutually completely with splined shaft simultaneously, its splined shaft is propped up in planet carrier female spline inside, its planet carrier nothing on splined shaft is rocked, with nut, add the fitness between packing ring locking cone degree axle and splined shaft again, the center pit of taper shaft by axle two by its jack-up, rotates planet carrier during detection to be used for detecting this interiors of products spline of planet carrier and other each size and position degree with deflection instrument.
Splined shaft in said mechanism, by external belt male splines, inside forms with the unthreaded hole of tapering, and simultaneously in order to facilitate splined shaft to play elastic reaction, its material should be selected spring steel material; Therefore for splined shaft can be supported under the effect of taper shaft, in the staggered processing in the two ends of splined shaft, not being divided into the end, uniform, width is the narrow elongated Tiaokou of molybdenum filament diameter.
Taper shaft in said mechanism, outside surface is that tapering smooth, that match with splined shaft forms.
Grouping mandrel in said mechanism, grouping mandrel should, according to product planet carrier design needs, for the accuracy of measuring, thereby design many core assemblies axle.When checking planet carrier product parts, should first check that on planet carrier, three fill planetary unthreaded hole size, select the grouping mandrel matching to assemble simultaneously, be convenient to accuracy and accuracy that this cubing checks product parts.
This patent tool has the following advantages:
1, to adopt material be spring steel to splined shaft, has good compression and the performance of upspringing, and can better realize splined shaft and be assemblied in dismounting in planet carrier part, and the taper fit of splined shaft and taper shaft is used, and improves the accuracy checking and the efficiency of accelerating inspection.
2, grouping mandrel adopts the planet carrier hole that the mandrel of minute different packet sizes matches with it to coordinate, and can better realize the accuracy that product parts checks.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this patent is further illustrated.
Fig. 1 is a kind of check wiring layout of tractor planet carrier cubing.
Fig. 2 be the cut-open view of splined shaft and A to B to view.
Fig. 3 is the front view of taper shaft.
In figure: 1. deflection instrument, 2. nut, 3. packing ring, 4. planet carrier, 5. grouping mandrel, 6. splined shaft, 7. taper shaft.
Embodiment
Below by embodiment, and by reference to the accompanying drawings 1, the technical scheme of accompanying drawing 2 and 3 pairs of this patents of accompanying drawing is described in further detail.
As shown in Figure of description 1, accompanying drawing 2 and accompanying drawing 3, a kind of planet carrier cubing of tractor, is mainly comprised of deflection instrument 1, nut 2, packing ring 3, planet carrier 4, grouping mandrel 5, splined shaft 6 and taper shaft 7, planet carrier 4 is tested part, grouping mandrel 5 is fixed in the unthreaded hole of planet carrier 4, splined shaft 6 with male splines is assemblied in planet carrier 4 female spline places, taper shaft with tapering 7 is coordinated mutually completely with splined shaft 6 simultaneously, its splined shaft 6 is propped up in planet carrier 4 female spline inside, its planet carrier 4 nothing on splined shaft 6 is rocked, with nut 2, add the fitness between packing ring 3 locking taper shafts 7 and splined shaft 6 again, taper shaft 7 uses deflection instrument 1 by tool jack-up by the center pit at axle two, during detection, rotate planet carrier 4 to be used for detecting planet carrier 4 these interiors of products splines and other each size and position degree.
Fairly simple convenience is made and used to this patent, part for the different female splines of the band of different product, by changing different splined shafts, can pass through disassembled simply taper shaft and splined shaft, by being placed on the rotation of different product on deflection instrument, make its etalon of apparatus detect its relevant position degree and size, can judge that whether product parts is qualified, not only efficiency is improved, and accuracy has also obtained corresponding raising.
