Detect the contact of bevel gear inner hole ball end chamfer line；
4), 2 measurement portion of gauge rod, 20 upper end is positioned to hanging down between 1 upper surface of positioning base with height gauge measurement standard
Straight height L3If L3Measured value is within its theoretical value variation range, then surface is tested bevel gear inner hole ball end chamfer height and closes
Reason, bevel gear are qualified, on the contrary then surface bevel gear is unqualified.
Above-mentioned steps 4) in L3Theoretical value fluctuation range calculation formula is as follows:
L3=L4-h2-L2
Wherein: as shown in figure 5, L4For table in the free end end face to upper positioning region 22 of 2 measurement portion 20 of standard setting gauge rod
The distance between face (upper 21 abutted surface of positioning region 22 and neck)；h2Change model for bevel gear inner hole ball end chamfer Height Standard value
It encloses；L2The axial distance between tested bevel gear inner hole ball end chamfer cusp is arrived for 2 measurement portion of standard setting gauge rod, 20 wedge angle 13,
Well-known theory value when for testing fixture design.It can thus be appreciated that: when the cubing 100 for detecting bevel gear inner hole ball end chamfer height is selected
Afterwards, L4、L2Value is given value, h2Variation only will drive L3Variation, due to h2Measurement process is complicated, so passing through measurement L3
Value counter can push away h2Whether within the scope of design value, judge whether the bevel gear product produced is qualified with this.
The cubing provided in this embodiment for being used to detect bevel gear inner hole ball end chamfer height has the beneficial effect that the present invention
It is skillfully constructed, it is easy to use, pass through the direct measurement to measurement portion, so that it may judge that bevel gear inner hole ball end chamfer height is
It is no within the variation range of design value, simplify the calculating process of existing bevel gear inner hole ball end chamfer height, improve inspection
Efficiency is surveyed, and achieves good detection effect in practice, scene can carry out each bevel gear produced after promoting
Real-time detection avoids the accident that previous bevel gear is scrapped in batch.
The above is not intended to limit the present invention in any form, although the present invention is disclosed with preferred embodiment
As above, however, it is not intended to limit the invention, any person skilled in the art, is not departing from technical solution of the present invention model
