Definitions
- the present invention relates to a method and a device for detecting the direction of a member having an asymmetrical outer periphery.
- the present invention relates to a vertically asymmetric member having a tapered surface or an eccentric curved surface on its outer periphery, for example, a disk-shaped, cylindrical or annular member, and more specifically, one of the components of an engine. More particularly, the present invention relates to a method and a device for detecting a direction such as a piston ring having a vertical direction.
- a piston ring which is one of the engine components, is a high performance piston capable of low fuel consumption and low oil consumption. Rings are required. Inner rings and eccentric BF (valley face) rings are examples.
- FIG. 5 shows an example of the inner ring 1 and the eccentric BF ring 2.
- a piston ring having a vertical direction such as the inner ring 1 and the eccentric BF ring 2 can function when the vertical direction is correct. That is, they are designed to perform the required functions only when they are mounted on the piston in the correct direction.
- the inner ring 1 has the inner surface la on the upper surface side, so that the inner peripheral edge lb on the lower surface of the ring is on the lower surface of the ring groove (not shown). Good sealing properties can be obtained by contact with pressure, and oil can be prevented from rising to the combustion chamber via the back of the ring.
- the inner ring 1 is twisted into a dish shape and attached to the piston groove.
- the effect of preventing the combustion gas from leaking, the effect of increasing the compression ratio, and the wedge effect the oil on the cylinder inner wall on the combustion chamber side is filled with oil. It has functions that make it easy to ride. That is, when the direction of the inner surface la is the lower surface, the above-described effects cannot be obtained, and the engine performance is reduced.
- disc-shaped, cylindrical or annular members such as a piston ring, a valve lifter, and the like, for which a field force has been required, have increased in shape and dimensional accuracy due to high functionality.
- the eccentric BF ring shown in () it is difficult to determine the vertical direction with the naked eye. I'm making it.
- high-precision piston rings and the like are also processed in a wide variety of processing steps. ) Is required. In the process of processing disk-shaped, cylindrical or annular members whose outer circumferences such as piston rings are vertically asymmetrical, it is very important to maintain the correct orientation.
- a commercially available laser displacement sensor having a minute spot is generally widely used.
- the laser is scanned according to the section to be measured, and the front surface or the back surface is determined based on the laser displacement.
- FIG. 6 shows a method of determining the direction of the piston ring 4 by the displacement sensor 3.
- the shape and dimensional specifications of the piston ring 4 to be inspected are grasped in advance, and the part which is being measured by the displacement sensor 3 is determined. It is necessary to judge the direction of the displacement data force obtained from the target. That is, here, the vertical direction of the piston ring 4 is determined from the difference between the measured displacement 1 shown in FIG. 6A and the measured displacement 2 shown in FIG. 6B. This is because the displacement sensor 3 itself measures the distance of the measurement reference point force of the displacement sensor 3 by the minute spot, and does not measure the shape of the piston ring 4 itself.
- the displacement sensor 3 or the piston ring 4 must be scanned, and there are problems such as a long measurement time and a large influence of vibration or temperature.
- it is not an effective method for items such as eccentric BF rings and peripheral tenor rings, for which it is difficult to determine the direction with the naked eye, because the direction cannot be accurately and easily determined from the viewpoint of resolution. That is, if the piston ring 4 is replaced with the eccentric BF ring 2 shown in FIG.
- non-contact direction determination methods other than laser include LED and halogen lighting.
- Image processing using Normally, a part that serves as an index for direction discrimination (for example, the entire inner surface of an inner ring) is illuminated by illumination, and the difference in brightness between the illuminated part and the other part is captured as an image by a CCD camera, and the brightness is adjusted to a certain value.
- the method used when determining based on the area and the number of pixels is used. In the case of this method, a lot of setup changes occur in the production of small items of various types with different cross-sectional shapes, and optimal lighting and camera positions and threshold values for image processing are adjusted according to the shape of the items. It must be changed.
- a direction determination method using a contact method there is a method in which a displacement of a contact portion is converted into an electric signal using a "lever type dial gauge" and the change is determined based on the change.
- this method can be easily measured, the method is subject to the point that the tip of the dial gauge is worn over time, the point that is greatly affected by vibration, and the cross-sectional shape and surface roughness of the direction discrimination target. Since the tip diameter of the dial gauge and the material must be selected each time, it is a practically difficult method because there are many factors that affect the accuracy and accuracy in operation, despite the simple principle.

- the eccentric BF ring P is opposed to the eccentric BF ring P in a tangential direction so that a gap between the eccentric BF ring P and the outer peripheral surface Pa can be imaged by the CCD camera 18. Therefore, the CCD camera 18 can capture an image in which the eccentric BF ring P and the reference block 13 are shadows (black images) and the background is light from the light source lighting device 15 (white images). it can. This makes it possible to acquire an image in which the height, width, and inclination of the protruding portion between the outer peripheral portion Pa of the eccentric BF ring P and the reference block 13 can be easily measured.
- the reference block 13 has a mirror surface at a portion that comes into contact with the outer peripheral portion of the eccentric BF ring P.
- the mirror surface has a surface roughness of RzO.1 or less.
- the eccentricity of the reference block 13 By making the portion in contact with the outer peripheral portion of the BF ring P a mirror surface, the light source illumination device 15 can output as much light as possible through the gap between the outer peripheral portion of the eccentric BF ring P and the reference block 13. Since the signal is amplified by specular reflection or diffuse reflection on the mirror surface of the reference block 13, the judgment is more accurate and easier.
- the value was about 1.8 times that of the eccentric BF ring P using a non-mirror reference block 13 with a surface roughness RzO.

- the light leaking part 25 on the side and the light leaking part 26 on the lower side are imaged by the CCD camera 18 and displayed on the monitor 22 via the discriminating means 21.
- the upper light leakage portion 25 is larger than the lower light leakage portion 26, so that the upper surface of the eccentric BF ring P Can be seen on the upper side.
- the direction can also be determined from the center of gravity. Of course, it is also possible to determine the direction depending on whether the contact portion is on the upper surface side or the lower surface side with respect to the width dimension of the eccentric BF ring P.
- the direction illuminated by the light illuminated toward the CCD camera 18 is determined based on the light leakage formed in the gap between the contact portion and the naked eye.

- the difference in light leakage is different, and the direction can be determined based on this difference. It is also possible to provide the reference surface 12 with a slope corresponding to the taper Ta without providing the reference block 13 with a taper!
- the difference in the degree of the gap depends on the front and back of the tenoring ring T. Can be further clarified, and S / N can be improved.
- the shape of the force reference block 13 described in the case where the taper 13a corresponding to the taper Ta of the tenor ring T is provided in the reference block 13 is applied to a part or the whole of the outer peripheral section of the piston ring.
