Description
Technical field
The invention belongs to technical field of internal combustion engines, more particularly, to a kind of protrusion height of oil sprayer measuring device.
Background technology
It does not have cylinder head and valve actuating mechanism for opposed-piston engine and opposed pistons opposed-cylinder engine, than conventional hair
Motivation parts are few, and fuel sprays into combustion chamber from cylinder jacket side and burns, research shows that：What fuel injector was mounted laterally starts
Machine, the protrusion height of fuel injector have a significant impact to combustion chambers burn performance, so as to influence the power of engine, discharge etc..
Therefore the engine laterally sprayed for the fuel injector developed for the first time, the protrusion height for measuring fuel injector are just particularly heavy
It will.
Invention content
In view of this, the present invention is directed to propose a kind of protrusion height of oil sprayer measuring device, is started with solving opposed pistons
The fuel injectors such as machine and opposed pistons opposed-cylinder engine are mounted on cylinder jacket side, i.e. fuel injector vertical gas cylinder sleeve axis is installed
Protrusion height of oil sprayer measurement problem.
In order to achieve the above objectives, the technical proposal of the invention is realized in this way：
A kind of protrusion height of oil sprayer measuring device, including arc block, guide rod, positioning sleeve and amesdial, the arc
In two opposites of block one be planar section another be cambered surface part, planar section is equipped with threaded hole, the cambered surface
Partial diameter is identical with the internal diameter size for the cylinder sleeve for installing fuel injector to be measured；The positioning sleeve is cylindrical structure, at axle center
Equipped with perforative endoporus；The guide rod includes the threaded portion and bar portion of one end, and threaded portion screws in threaded hole, and bar portion passes through
The endoporus of positioning sleeve and positioning sleeve clearance fit；The bar portion is pierced by positioning sleeve, and its end face is used to connect with the gauge head of amesdial
It touches.
Further, the cylindrical surface of the positioning sleeve cylindrical structure is equipped with the groove part of annular, the concave part
Mounting O-shaped rings in point.
Further, the end face of the bar portion is plane.
Relative to the prior art, the present invention has the advantage that：
(1) present invention is capable of the angle of self-adjusting positioning sleeve and mounting hole of oil sprayer, the concentricity both ensured, so as to subtract
The measurement error that small measuring device setting angle is brought makes measured value ensure measurement accuracy closer to actual value.
(2) the configuration of the present invention is simple, it is easy to implement.

Specific embodiment
It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the present invention can phase
Mutually combination.
The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
A kind of protrusion height of oil sprayer measuring device of the present invention, as shown in Fig. 1 to 5, including arc block 1, guide rod 2, O-shaped
Circle 3, positioning sleeve 4 and amesdial 5,
In two opposites of the arc block 1 one be planar section 13 another be cambered surface part 12, planar section
13 are equipped with threaded hole 11, and the diameter of the cambered surface part 12 is identical with the internal diameter size for the cylinder sleeve 7 for installing fuel injector to be measured；
The positioning sleeve 4 is cylindrical structure, is equipped with perforative endoporus 41 at axle center, on the cylindrical surface 42 of cylindrical structure
Groove part 43 equipped with annular, the O-ring 3 is mounted in groove part 43, for coordinating with mounting hole of oil sprayer；
The guide rod 2 includes the threaded portion 21 of one end and bar portion 22, and threaded portion 21 screws in threaded hole 11, bar portion 22
Across 4 clearance fit of endoporus 41 and positioning sleeve of positioning sleeve 4；
The bar portion 22 is pierced by positioning sleeve 4, and its end face is plane, for being contacted with the gauge head of amesdial 5.
During measurement:
Two O-rings 3 are installed in the groove part 43 of positioning sleeve 4, positioning sleeve 4 is then installed to oil sprayer bushing
