Wherein, 1, lighting device; 2, tripod centering guide; 3, proofread and correct telescope.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in the figure, this two axis holes casing coaxality measuring mechanism comprises light-emitting device 1, two triangle centering guides 2 and proofreaies and correct telescope 3; Described correction telescope 3 adopts the axially two-way prism of symmetry; Described triangle centering guide 2 is made up of 3 feets, and wherein two feets become 90 degree to arrange, and another feet is on the extended line of the angular bisector of preceding two feets; The outside cylinder coaxial with described tripod centering guide 2 focus targets is provided with a support that is used for installing clock gauge; Described light-emitting device 1, the axis of proofreading and correct telescope 3 and being arranged on the measurement target on the triangle centering guide 2 are on same straight line.
Correction telescope in this device has adopted a special optical texture when measuring---axially symmetrical two-way prism.Can obtain two orthogonal collimation plane by two-way prism, in this way, the direct side-play amount of measurement target on these two collimation plane, it has avoided straight instrument to obtain indicating value by the conversion that level crossing tilts.Therefore, adopt the right alignment in this apparatus measures hole, avoided problem between the Kong Yukong, the problem includes: the span problem.But,, still can't solve the inconsistent problem in aperture that runs into when measuring right alignment if its target seat is not redesigned transformation.Want to address this problem, that just must introduce " tripod centering guide " technology." tripod centering guide " technology adopts the target of three pin support equipment, wherein two pin become 90 degree to arrange, the another pin is on the extended line of preceding two pin angular bisectors, (the convenient adjustment) three heels all are adjustable removable according to the size in aperture, with the coaxial outside cylinder of " tripod centering guide " focus target on, a support that is used for installing clock gauge is arranged, so that center and the measured hole center of control " tripod centering guide " target on same point, have been avoided the target's center of instrument in the measurement and measured hole center decentraction and have been produced measuring error.According to " tripod centering guide " these design features, if we are retrofitted on the focus target position of tripod centering guide proofreading and correct telescopical measurement target, the problem that differs in the aperture that occurs in measuring for axle suspension bearing box is by the adjustment of clock gauge on the centering guide, make that measurement target and each measured hole are concentric just can to satisfy the measurement purpose, and, test for two hole right alignmenies can't be installed problems such as target and calculating, also becomes and is readily solved.Because during the right alignment of the accessory of employing correction telescope and repacking---tripod centering guide measured hole, the every bit data of measuring are exactly the real data of this point, it is independent of other measured points, before when being different from straight instrument and measuring a bit and the back all be closely bound up a bit, therefore also just no longer need to calculate cumulative errors.And this locating mounting method has also been eliminated the casing endoporus greatly and has been added the influence of the local defect of generation in man-hour to accuracy of measurement.Like this, when measuring two hole right alignmenies, only need in each hole, appoint and get two diverse locations placement targets (being the tripod centering guide), just can measure the locus of this axis hole, continue by same mode, measure the locus of another axis hole continuously, thereby just draw the right alignment in diaxon hole through calculating.
