Turn so that detection 2133 reversely rotates and upwards resets；According to the principle of " drift is crossed, no-go gage is only qualified ", then this valve
Lid screw thread is qualified；If drift 21330 rotates through the screw thread on valve gap, detection 2133 continues to be rotated down motion, as
When really no-go gage 21331 rotates also through screw thread on valve gap, now system manipulation lifting drives motor 22 and detection head to drive electricity
The output shaft reversion of machine 211 so that detection 2133 reversely rotates and upwards resets；According to " drift is crossed, no-go gage is crossed as not conforming to
Lattice " principle, then this valve gap screw thread is relatively big, and defective, this valve gap is directly scrapped；When detection 2133 needs to change, will adjust
Joint ring 2132 rotates up in connecting shaft 2131, and now, top pressure spring makes stationary jaw 2134 the most upwards reset, and will be pressed from both sides
Tight detection 2133 discharges, and then detection 2133 plug-in mounting needing to use enter the installation counterbore of connecting shaft 2131
In, thereafter, regulation ring 2132 is rotated down in connecting shaft 2131, stationary jaw 2134 is pushed up downwards pressure, top pressure spring
Compress so that the top pressure surface of stationary jaw 2134 all withstands detection 2133, detection 2133 is fixedly clamped.
The foregoing is only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every
Utilize equivalent structure or equivalence flow process conversion that this utility model description and accompanying drawing content made, or be directly or indirectly used in
Other relevant technical fields, are the most in like manner included in scope of patent protection of the present utility model.
