Description
Technical field
The present invention relates to a kind of test measuring device, detection means and detection method especially about internal taper hole.
Background technology
As machinery industry technology is constantly lifted, the design of torsion is transmitted in every profession and trade by being interference fitted
Adopt extensively.For a long time, people gradually experience cone match assembling, torsion transmission, maintenance etc. have it is only
Thick superiority, so from small to several kilogram, all designed to several tons of even more big products using cone match greatly.
In the process of internal taper hole, in order to accurately control taper hole datum diameter and taper（Angle）Value, it is existing logical
, most efficient method be exactly using special feeler gauge come these sizes of indirect control.For the part of small internal taper hole, feeler gauge one
As only within several kilograms, the Site Detection of very convenient operating personnel.Due to the progress of technology, big internal taper hole（Such as ￠
200mm）Design tends to normality.In these internal taper hole process, if still detecting internal taper hole correlation by the way of feeler gauge
Corner, hence it may becomes difficult to realize.Because the feeler gauge weight of these specifications is up to more than ten kilograms and even more weighed, operating personnel can not be square
Picking up, accurately detecting just, put even if being risen using overhead traveling crane, also because of overhead traveling crane itself the shortcomings that, be easily caused between feeler gauge and product and produce
The raw potential danger such as collide with, scratch.Once these danger occur, measurer, product rejection may be caused, bring serious economic damage
Lose.
Typically, for the Product processing containing big internal taper hole, product is must take into consideration when from equipment and detection mode
