Embodiment
The utility model will be further described by reference to the accompanying drawings for embodiment below.
A kind of axletree conicity measurement mechanism, comprises axial positioning mechanism 1, hoop detent mechanism 2, blade 3, measuring mechanism 4 and difference digital display module.Axial positioning mechanism 1, hoop detent mechanism 2, measuring mechanism 4 are installed on blade 3, and measuring mechanism 4 is connected with difference digital display module by data line or wireless mode.
Axial positioning mechanism 1 comprises axial location support 6 and each one of axial location block 7; Hoop detent mechanism 2 comprises hoop locating rack 8 two and hoop locating piece 9 four; Blade 3 there is guide frame 10; Measuring mechanism 4 comprises fixed length reference block 11, digital display dial gauge 12, clock gauge lock-screw 13, dial indicators rack 14, slide 15, cover plate 16, digital display calliper 17, slide calliper rule support 18; Be the circuit and the display module that realize this structure tapering computational algorithm with difference digital display module, realize intelligent computing by horizontal line and radial displacement.
Described hoop detent mechanism 2 is according to the arc size of actual measurement axletree geometric properties design hoop locating rack; And after two groups of locating racks are arranged on blade 3, the dead in line of respective circle center line connecting and measurement axletree can be ensured.
The fixed length reference block 11 of described measuring mechanism 4 can according to the distance setting for measuring between axletree locating surface and measured zone; The arc size of dial indicators rack 14 has actual measurement axletree size characteristic to determine, makes this support center of circle on axle axis, the dead in line of two digital display dial gauges 12, and perpendicular to axle axis.
