(2) the position measurement process of cylinder head fuel hole is simple, quick, accurate, can quickly judge cylinder head fuel oil
Whether the position degree in hole is qualified, improves production efficiency；
(3) test pin and location hole are interference fitted, and prevent test pin in detection instrument assembling process from deviating from location hole, limitation
Test pin rotation, while can also be improved the concentricity of test pin and location hole, improve measurement accuracy；
(4) side of handle opens up flat position and twill, and rubbing for gripping handle is improved convenient for gripping handle power output, twill in flat position
Wipe power.
Detailed description of the invention
Fig. 1 is the utility model structure diagram；
Fig. 2 is agent structure schematic diagram；
Fig. 3 is main body left view.
Specific embodiment
With reference to embodiment and compares attached drawing the utility model is described in further detail.It should be emphasized that
It is that following the description is only exemplary, rather than in order to limit the scope of the utility model and its application.
Referring to the following drawings, non-limiting and nonexcludability embodiment will be described, wherein identical appended drawing reference indicates
Identical component, unless stated otherwise.
Referring to Fig.1-3, a kind of cylinder head fuel hole position measurement tool, the tool include main body 1, test pin 3, hand
Handle 2.Main body 1 is cylindrical body comprising embedment end 15, measurement end 14, the position shape that the embedment end 15 is engaged with measurement end 14
At cascaded surface, the two is integrally formed, and central coaxial.The diameter at the embedment end 15 is less than the diameter of measurement end 14.It is measuring
The end face at end 14 opens up axial location hole 12, and the location hole 12 runs through two end faces of the measurement end 14 and extends to institute
Embedment end 15 is stated, forms arch groove 13 in the side at embedment end 15.The diameter of the arch groove 13 is matched with test pin 3.It is described
Location hole 12 has 2, and there is matched arch groove 13 in the side at embedment end 15, the position and fuel hole that location hole 12 opens up
Pin hole normal place it is corresponding.Test pin 3 is arranged in location hole 12, and 3 top of test pin and location hole 12 are interference fitted, under
Portion extends in the arch groove 13 at the embedment end 15, using as measuring basis.The end of the measurement end 14 extends outward
Thread segment 11, the handle 2 are threadedly coupled with the thread segment 11 of the measurement end 14.The side of handle 2 open up flat position and tiltedly
Line, convenient for holding power output, twill improves the frictional force of gripping handle for flat position.For the accuracy for improving measurement, main body 1 and test pin
