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.
A kind of piston protrusion height measuring device as shown in Figs. 1-5, including power device 1, fixed plate 9, sensor (4,
5,6,7,8), measurement plate 3, spring 2, supporting studs 11, the power device 1 connect with the fixed plate 9.In the present embodiment with
Cylinder pushes fixed plate 9 to be displaced as power device 1, cylinder.The sensor (4,5,6,7,8) is fixed on the measurement plate 3
On.The sensor has 5, wherein 3 sensors (4,5,6) are positioning group, and in addition 2 sensors (7,8) are
Measurement group.Referring to Fig. 3,3 strips 33 and installation for installing the positioning group sensor are offered in the measurement plate 3
2 long arc-shaped holes 32 of the measurement group sensor.3 sensors of the positioning group are in triangular distribution, 2 arcs
Long hole 32 is with the center symmetric setting of measurement plate 3.It designs strip hole and adapts to different engine blocks, practical, design arc is long
The installation site of measurement group sensor is adjusted to obtain more accurate measurement data in hole.The lower surface of the measurement plate 3 is set
It is equipped with 3 limited blocks 12, the lower surface is towards piston 10.3 limited blocks 12 are used to support measurement plate 3, while can also protect biography
Sensor.The measurement plate 3 is connected to the underface of the fixed plate 9 by the supporting studs 11；The spring 2 is located at described
Between fixed plate 9 and the measurement plate 3 and it is set in the outsides of the supporting studs 44.When measurement, supporting studs 44, spiral shell are utilized
Mother connects measurement plate 3 and fixed plate 9 integral, and adjusting nut makes measurement plate 3 and fixed plate 9 by the elastic force of spring 2.The branch
There is interval in the junction of support stud 11 and the fixed plate 9, measurement plate 3.
Specifically, the cylinder of the supporting studs 11 is second level ladder column, and the diameter of two sections of cylinders at least differs one times.
The supporting studs 11 and the fixed plate 9, measurement plate 3 junction between be divided into 0.75-2mm.The purpose that interval is arranged exists
In the space waved to the offer of supporting studs 11.The big section 111 of the supporting studs 11 is connect with the measurement plate 3 and junction
Between be divided into H, be divided into G between segment 112 and the connection of the fixed plate 9 and junction.The interval H is less than interval G.In use, solid
Fixed board 9 by cylinder promotion and with the segment of supporting studs 11 be guiding move up and down.The segment of supporting studs 11 upward, will not
Engine body is damaged, meanwhile, the confined planes 12 that the big section 111 of supporting studs 11, segment 111 are formed can control fixation
The distance that plate 9 pushes is also used as the confined planes of the swing of supporting studs 11.
The application method of the present apparatus, includes the following steps:
Zero point correction: adjustment positioning group, the sensor position of measurement group avoid sensor from interfering with engine, make
It is pressed under limited block 12 with one piece of dressing plate, saves the data of this five sensors respectively, be averaged and sat as zero point
Scale value Q；
Measurement: starting cylinder, cylinder rod pushes fixed plate 9, measurement plate 3 to bottom offset, until the lower surface of limited block 12
It is abutted with engine surface, records the real value of 5 sensors (4,5,6,7,8), be averaged R and subtract zero point coordinate value Q again
Obtain measurement level value L；Cylinder rod continues elongation 10-20mm compressed spring 2 downwards, increases the elastic force of spring 2；It transfers and lives
10 displacement of plug, the data of 2 sensors (7,8) of positioning group are averaged M and subtract level value L again and obtain piston 10
Projecting height value.
Because measured engine positioning consistency is poor, the limited block 12 under measurement plate 3 cannot be all flat with engine
Face abuts, and causes the benchmark zero-bit Q of displacement sensor and engine plane zero locatino when measurement inconsistent.The present apparatus utilizes spring
2 overcome the technical problem.Specifically, when measurement, spring 2 keeps high-tension, and spring 2 squeezes measurement plate 3 downwards, makes 3 limits
Block 12 is abutted with engine plane, guarantees that measurement plate 3 is parallel with engine plane, measurement data is more accurate.
It would be recognized by those skilled in the art that above description make numerous accommodations be it is possible, so embodiment and attached
Figure is intended merely to describe one or more particular implementations.
Although having been described and describing the example embodiment for being counted as the utility model, those skilled in the art will be bright
