Description

The engine piston top dead centre is measured frock
Technical field
The utility model relates to a kind of measurement frock, relates in particular to a kind of each cylinder top dead centre of piston front engine that is unkitted and measures frock.
Background technology
At present, in the assembling of oil pump for engine, a lot of types are to have adorned piston earlier to refill oil pump, but some type also can adorn oil pump and refilled piston, this according to model structure again in conjunction with the needs of assembly technology.These two kinds of dress methods are distinguishing, adorned piston, can measure the piston protrusion height and judge the cylinder top dead centre, find after top dead center, refill the injection timing of the respective cylinder of modulated good monoblock pump, Zhuan oil pump just can reach the injection timing of complete machine like this, if first loading pump is not also adorned piston, just be difficult to reach the timing of oil pump and the timing unification of bent axle, engine is difficult to be started or not to start thereby cause, in view of above reason, need a kind of measurement engine piston top dead centre of special use to measure frock.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, easy to manufacture, easy to install, the frock that can accurately measure the engine piston top dead centre behind the bent axle is installed.
Technical solution of the present utility model is such, comprise clamping sleeve, annular knurl flat head screw, dial gauge lid, spring, gauge rod, dial gauge base, screw, dial gauge, clamping sleeve is inlayed into dial gauge lid, the annular knurl flat head screw is screwed into dial gauge lid screw, spring is installed on the gauge rod, and gauge rod is put in the percentage gauge stand again, and screw is screwed into dial gauge base screw, the dial gauge lid is screwed into the dial gauge base of back-outing, and dial gauge is put described clamping sleeve into and compressed.
Clamping sleeve is bumped into the dial gauge lid, and the annular knurl flat head screw is screwed into dial gauge lid screw, fixedly dial gauge.
Between gauge rod and the dial gauge spring is arranged.
The lift of gauge rod equals the length of gauge rod slot to make way.
Gauge rod one end is the plane, and the other end is a semi circular surface.
Dial gauge base periphery has bolt hole, the lift of positioning control gauge rod.
The base portion of dial gauge base is fluted.
Owing to adopt above-mentioned technical scheme, the utlity model has following beneficial effect: simple in structure, be convenient to make, easy to operate, cost is low, and is reusable, safe and reliable.
