Description
Technical field
The zone location that the design is used in the measurement of engine jacket inner surface corrosion situation.
Background technology
Cylinder jacket in use, due to reasons such as mechanical load, thermic loads, easily produces frictionally damage and by corruption
Erosion, equipment fatigue and increasingly aging so that fault rate substantially rises.Measured at present for existing cylinder sleeve inner surface corrosion situation
In, it is to utilize in general measurer, such as inside micrometer or dial bore gage, is determined by estimating progress rough estimate corrosion region
Position, can produce certain range estimation error, and existing angle and depth localization be by manually measuring respectively, can also deposit during Data Integration
In very big error.
The content of the invention
The technical problems to be solved by the invention are：In the measurement of available engine cylinder sleeve inner surface corrosion situation, mainly
It is by estimating rough estimate corrosion zone location, and area's angle of detecting a flaw need to measure respectively with depth, easy in data analysis
Produce calculation error.
For above technical problem, the technical solution used in the present invention is：A kind of cylinder sleeve inner surface flaw detection area is provided
Domain positioner, the device are made up of dial, graduated scale and neck, and wherein graduated scale is provided at both ends with plane mirror support, point
Mirror is not arranged not in opposite directions, and it is with graduated scale into 45°Angle, graduated scale mounting groove, width and graduated scale one are provided with neck
Cause, each several part combination can be tested during measurement.
In test process：Dial is anchored on cylinder sleeve first, overlaps its inner surface；Neck is put into dial
On so that the outer surface of neck overlaps with the inner surface of dial；Graduated scale is put into neck so that the outer surface of graduated scale
It is close to the bottom land of neck；After the completion of assembling, rotate neck and translate graduated scale, cylinder sleeve inner surface can be observed by mirror
Scar site, it is determined that after and record.
The dial is mainly used in positioning measured piece cylinder sleeve and neck, and according to scale thereon come positioning cylinder set
The circumferential position of inner surface scar, dial range are 360°, scale division value 1°。
The graduated scale is mainly used in measuring the axial height of cylinder sleeve inner surface scar, and the range of graduated scale is 300mm,
Scale division value is 1mm.
The neck is mainly used in location graduation chi and reading, and is rotated on dial to measure the circle of inner surface scar
All positions.
The design principle of the present invention is the principle of reflection using light, using a pair of mirrors, by cylinder sleeve inner surface be not easy into
The scar of row observation and measurement is transformed into easily observed position, so as to improve the accuracy of measurement and operability.
The beneficial effects of the invention are as follows：Angle positioning is realized with being measured while depth localization；Reflected using level crossing
Principle is measured, when effectively reducing artificial range estimation due to sight can not it is vertical with corrosion region caused by error；Using cut
Face is fan-shaped deep calibration chi and locating piece, effectively reduces error caused by manual measurement.

Embodiment
As shown in figure 1, a kind of new cylinder sleeve inner surface flaw detection regional positioning device, its basic structure include dial
2nd, graduated scale 3 forms with neck 5；Graduated disk structure is as shown in figure 3, its scale is as shown in Figure 4；Graduated scale structure as shown in figure 5,
Graduated scale is provided at both ends with plane mirror support 6, respectively opposite arrangement mirror, with 3 angle at 45 ° of graduated scale, the quarter of graduated scale
Degree is as shown in Figure 6,7；The structure of neck 5 is as shown in figure 8, be wherein provided with graduated scale groove 7 on neck 5, for installing graduated scale 3,
Its width is consistent with graduated scale.
Mode of operation in actual use：As shown in Fig. 2 dial 2 is anchored on cylinder sleeve 1, overlap its inner surface；
Neck 5 is put on dial 2 so that the outer surface of neck 5 overlaps with the inner surface of dial 2；Mirror 4 is posted at both ends
Graduated scale 3 is put into neck 5 so that is close to the bottom land of neck 5 in the outer surface of graduated scale 3；After the completion of assembling, as shown in Fig. 2 rotation
Turn neck 5 and translate graduated scale 3, the scar site of cylinder sleeve inner surface can be observed by mirror 4, it is determined that after and record.
Involved in the present invention is a kind of special flaw detection regional positioning device, can be according to measurand come apparatus for regulating chi
It is very little, for example suitable for internal diameter be 100mm, external diameter 130mm, the cylinder sleeve highly in the range of 0 ~ 300mm.Due to the application energy
It is enough to be embodied in a variety of forms without departing from the spiritual or substantive of invention, it should therefore be appreciated that above-described embodiment is not limited to appoint
What foregoing details, and should widely being explained in the spirit and scope that claim is limited, thus fall into claim or
The adjustment of overall dimension in its equivalent scope or the selection to similar material are covered using all should be claim.
