Motion detection device.
Background technique
The channel of fuel feeding when oilhole is engine operating, it is unimpeded that oilhole guarantees that oil liquid recycles in entire engine, into
And guarantee the normal work of engine, if oilhole can not once penetrate through main oil gallery, will lead to machine oil can not be successfully supply, produce
A series of raw engine failure, such as rocker arm bushization watt, VVT-i (variable valve timing system of engine) are not available, because
This, engine body guarantees that the perforation of oilhole is highly important in processing.
Currently, due to oilhole small (diameter phi 6mm or so) and hole is deeper during the machining of oil hole of engine body top surface,
It is easy to appear breaking, tipping in processing, simultaneously because cylinder block strength is big, is easy to bore partially, all can cause oilhole that can not penetrate through, separately
Outside, lathe has outer protective cover, and Noise In Workshop is big, if gone wrong in process, manually more difficult discovery, product is easy to deposit
In hidden danger of quality, this requires must detect the connectivity of oilhole in process.
Inventor has found that there is also following defects to the detection of oilhole on production line at present: existing in practical application
Detection mode relies on the hand-held detection of testing staff to be sequentially inserted into for the oilhole on engine body mainly to judge that oilhole is
No perforation, heavy workload, working efficiency is low, if always working on unicity operation for a long time, is also easy the body to testing staff
Body health impacts, meanwhile, during manual detection, it is also easy to appear missing inspection problem, makes automobile storage in major quality
Problem.
Therefore, a kind of engine body oilhole automatic detection device is developed, not only there is urgent researching value, it may have
Good economic benefit and commercial application potentiality, this is exactly where the power that the utility model is accomplished and basis.
