Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is front view of the present invention;
Fig. 2 is vertical view of the present invention;
Fig. 3 is right view of the present invention.
Embodiment
Below with reference to accompanying drawing, the present invention is described in detail, as shown in the figure: the gear keyway symmetry cubing of the present embodiment, comprises mandrel 1, surveys post 2 and dial gauge 3.Mandrel 1 is vertical multidiameter, comprise bottom shaft part 101, flange 102, transition shaft part 103 and top shaft part 104 from the bottom to top successively, in pilot hole 901 wherein on bottom shaft part 101 inserted base 9, and be overlapped on the end face of base 9 by the lower surface of flange 102, the external diameter of top shaft part 104 and the diameter of bore of gear 100 are worked as, gear 100 inserts mandrel 1 along top shaft part 104 from top to bottom by its center pit, and is supported by the lower surface of upper surface to gear 100 of transition shaft part 103.In order to the symmetry of its transverse tooth thickness relative of the keyway on prototype gear 100 center pit, the top shaft part 104 of mandrel 1 circumferentially there is positioning key 4, this positioning key 4 matches with the keyway of gear 100, when gear 100 inserts top shaft part 104, positioning key 4 also inserts in the keyway of gear, is namely positioned by positioning key 4 pairs of gear 100 circumferences.Survey post 2 and be positioned horizontally in gear 100 side, and near positioning key 4, survey post 2 and have a teeth groove 5 near one end of gear, this teeth groove 5 can hold tooth gear 100 being in same diameter with positioning key 4, that is, survey post 2 axis, teeth groove 5 center line, positioning key 4 center line and mandrel 1 center conllinear, and the profile of tooth of the profile of teeth groove 5 and gear 100 matches.Survey one end that post 2 can go the long way round from gear to swing, when mandrel 1 loading the gear of the different error of same specification, due to the position disparity of keyway and gear tooth thickness, cause the transverse tooth thickness inserted in teeth groove 5 to make survey post produce different oscillating quantities, and measure oscillating quantity to be calculated to be gear keyway relatively and the symmetry of transverse tooth thickness by dial gauge.
Concrete, first measure a gear part as standard component, standardized element be placed on mandrel 1, adjust dial gauge to zero, after taking off standard component, mandrel is put into other gears, then by and detected value is relative value, namely relative to the value of standard component.This cubing convenient operation, saves the operation of three-dimensional, is applicable to mass detection.
Such scheme needs dial gauge directly to measure survey post 2, not easily install fixing owing to surveying post 2, for this reason, be connected with switch block 6 in survey post 2 one end away from gear, described switch block 6 rotates centered by reference column 7, one end relative with surveying post 2 on described switch block 6 is connected with standard column 8, the axis of described standard column 8, center and the axis collinear surveying post 2 of reference column 7, the survey post 2 produced by gear swings centered by reference column 7, and pass to standard column 8 by switch block 6, the oscillating quantity produced by the direct measurement standard post 8 of dial gauge 3, compare and directly measure post 2, the oscillating quantity of measurement standard post 8 is more prone to.
As the further improvement of technique scheme, described mandrel 1 is arranged on base 9, and described reference column 7 is arranged on can along on survey post 2 in axial sliding planker 10 on base.Concrete, on base 9, corresponding planker 10 both sides are respectively equipped with two and slide the guide rail 11 play the guiding role to planker, and using the center line between two guide rails 11 as the mandrel pilot hole 901 of base 9, mandrel 1, survey the centre of location of post 2, reference column 7 and standard column 8.Described guide rail 11 is connected with press strip 12, and the inner side of the relative planker of described press strip 12 is pressed on planker 10, and the jerk value of also measurement standard post 8 on planker 10 installed by described dial gauge 3.By planker 10 along surveying the movement of axis of a cylinder to namely gear radial direction, can measure the even symmetrical degree of gear keyway on radical length, measurement accuracy is higher.
As the further improvement of technique scheme, described survey post 2 and standard column 8 insert in switch block 6 with the form of clearance fit respectively, are convenient to dismounting, the replacing of surveying post 2 and standard column 8.
Due to mandrel pilot hole 901, mandrel 1, survey post 2, reference column 7 and standard column 8 are located with the center line of two guide rails 11, the installation location of guide rail 11 on base 9 must be precisely, guide rail 11 is connected by register pin 13 with base 9, the hole that guide rail and base 9 are installed for register pin 13 adopts to join and processes as mode, what is called is joined, after base 9 and guide rail 11 being adopted clamp to locate on lathe together with the pin-and-hole of locating and machining pin 13, then register pin 13 is inserted in pin-and-hole, so just guide rail 11 accurately can be located on base 9, and press strip 12 is linked together with base 9 by the bolt 14 running through guide rail 11.
What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
