With reference to figure 1-3, a kind of piston pin hole verticality measuring instrument includes groove 1 for placing piston 3 and passes through piston
The both sides of the mandrel 2 of pin hole, groove 1 are respectively equipped with a linear transducer 10, and two linear transducers 10 are parallel with groove 1 to be set
It sets, and two linear transducers 10 are separately positioned on two equal positions of groove length, more preferably, two linear transducers
The line of level, i.e., two linear transducers is vertical with groove length direction, and two linear transducers 10 are respectively measuring length
Spend distance of the sensor 10 apart from mandrel 2；It is additionally provided with clamping fixture, to be fixed the piston being placed in groove 1.
Operation principle：First piston is positioned in groove, groove is horizontally disposed, and piston is parallel with groove, and mandrel is inserted into simultaneously
Then pin hole on piston is allowed to fixed with clamping fixture clamping piston.Start two linear transducers, uses respectively
Come measurement sensor to pass through pin hole mandrel both ends distance, if readings are consistent for two sensors, that is, indicate pin hole with
Piston is completely vertical, then indicates out of plumb if there is difference, difference is bigger, and verticality is lower.Since piston pin hole needs to be inserted into
Mandrel reserves insertion to mandrel and exposes the space at both ends so piston is put into the radius that the height in groove is less than piston.
In the above-mentioned technical solutions, the cross section of groove 1 is V-type or inverted trapezoidal.V-type or inverted trapezoidal can make piston
It is caught in groove, plays certain fixed function.
In the above-mentioned technical solutions, one end bottom of mandrel 2 is equipped with support construction 7, and support construction 7 is fixed on groove 1
