Description
Technical Field
The present invention relates to a surface inspection tool and a surface inspection method for inspecting surface quality of a part, and more particularly, to a surface inspection tool and a surface inspection method for determining whether an inspection target on a surface to be inspected is located in a critical area.
Background
In industrial production, it is often necessary to inspect the surface quality of components, for example to identify defects on the surface to be inspected, and in the event of defects, to determine whether the defects affect the use of the surface to be inspected, i.e. whether the defects are located in critical areas of the surface to be inspected.
For example, in the assembly of an automobile engine, the sealing performance of the cylinder has a great influence on the working condition of the engine. When the cylinder is not tightly sealed, the air leakage of the cylinder is caused, the compression force of the cylinder is insufficient, and when the air leakage of the cylinder is serious, the power of an engine is obviously reduced, even the engine cannot work. The engine cylinder head and the engine cylinder block are important parts of an automobile engine, are often contacted with high-temperature and high-pressure fuel gas, and therefore bear large thermal load and mechanical load, and the sealing performance of the engine cylinder head and the engine cylinder block is an important index of the sealing performance of the cylinder. At the time of assembly, the cylinder head and the cylinder block surface cannot be scratched in the region (critical region) where they are fitted with other components such as the head gasket, and therefore the surface of the critical region must be sufficiently inspected.
Currently, part of the surface inspection area cannot be completed online by an inspector, but needs to be determined by a coordinate Measuring machine CMM (coordinate Measuring machine), the inspector needs to carry the parts to a dedicated room where the CMM is stored, and the CMM inspection requires a long time, and thus is inefficient.

Detailed Description
The surface inspection tool and method of the present invention are widely applicable to a variety of situations where a surface needs to be inspected. The engine block is described in detail below as an example, and is not intended to limit the tools and methods of the present invention.
Referring to fig. 1, an engine body 1 is mainly composed of four parts: an oil pan 2, a cylinder block 3, a cylinder head 4, and a cylinder head cover 5.
The oil pan 2, also called the lower crankcase, is used to store lubricating oil and to close the upper crankcase. The oil pan is stressed little and is generally stamped from sheet steel, and its shape depends on the overall layout of the engine and the capacity of the engine oil.
The cylinder block 3 is generally cast in gray cast iron, and the upper cylindrical cavity of the cylinder block is called a cylinder 9, and the lower half part is an upper crankcase for supporting a crankshaft, and the inner cavity of the upper crankcase is a space for the crankshaft to move.
The cylinder head 4 is attached to the upper surface of the cylinder block 3, and seals the cylinder 9 from above to form a combustion chamber. The cylinder head 4 is often in contact with high-temperature and high-pressure combustion gas, and thus is subjected to a large thermal load and a large mechanical load. The cylinder cover 4 is also provided with an air inlet valve seat, an air outlet valve seat, an air valve guide pipe hole, an air inlet valve, an air outlet valve, an air inlet channel, an air outlet channel and the like. The cylinder cover of the gasoline engine is provided with a hole for installing a spark plug, and the cylinder cover of the diesel engine is provided with a hole for installing a fuel injector. The cylinder head 4 is generally cast from gray cast iron or alloy cast iron, and aluminum alloy has good thermal conductivity and is advantageous for increasing the compression ratio, so in recent years, aluminum alloy cylinder heads are increasingly used.
The cylinder head cover 5 is mounted on the cylinder head 4, covers and seals the cylinder head 4, and keeps the engine oil inside while isolating contaminants such as dirt and moisture from the outside. In addition, the head cover 5 isolates the oil from the air, which may form an oil mist during operation of the engine, and the cooler inner surface of the head cover 5 collects the oil mist, causing the oil to condense and flow back down to the oil pan 2.
The matching between the four parts needs strict sealing to prevent air leakage, water leakage and oil leakage, so the smoothness requirement on the matching surface between the parts is higher. And cylinder gaskets 6, 7, 8 (see fig. 1) are provided between the mating parts for ensuring sealing between the mating parts. The cylinder head gasket is generally made of metal and asbestos.
Taking the mating surface between the cylinder head 4 and the cylinder head cover 5 as an example, the head gasket 6 is disposed therebetween. Referring to fig. 2, there is shown a cylinder head 4 and a head gasket 6 mounted on an upper surface thereof. To ensure a sealing fit between the surface of the cylinder head 4 and the head gasket 6, the surface of the cylinder head 4 that coincides with the head gasket 6 (referred to as the critical area) cannot be scratched. As described above, the cylinder head 4 is generally made of an aluminum alloy, and therefore has lower hardness than a steel member. In actual production, many other parts of the automobile are made of steel or other materials of higher hardness, and therefore the mating surfaces (e.g., upper surfaces) of the cylinder head 4 and the other parts are easily scratched by other harder parts in a workshop to cause scratches. If scratches occur in the critical areas, which may affect the seal between the cylinder head 4 and the head gasket 6, further processing of the mating surfaces of the cylinder head 4 may be required to eliminate the scratches and even to scrap the cylinder head 4 directly.
In the inspection process, whether scratches exist on the mating surface of the cylinder head 4 is first judged by an inspector with naked eyes, and if scratches exist, it is necessary to further inspect whether the scratches exist in a critical plane. According to the existing method, when an inspector cannot judge whether the scratch is located in the critical area with the naked eye, a three-coordinate measuring machine CMM is required for accurate judgment.
As known to those skilled in the art, the basic principle of a CMM is to place a part to be measured in a measurement space allowed by the CMM, precisely measure the values of three coordinate positions in space of points on the surface of the part to be measured, process the coordinate values of the points by a computer, fit the coordinate values to form measurement elements, and mathematically calculate the shape, position tolerance and other geometric data of the part to be measured. CMM can perform high-precision measurement. However, the CMM needs to be operated under a constant temperature, and therefore, when the above CMM needs to be used to inspect surface scratches of the cylinder head 4, the cylinder head 4 needs to be transported into a constant temperature chamber in which the CMM is stored to perform precise measurement, thereby determining whether the scratches are located in a critical area. Therefore, the inspector cannot judge the scratch on line, and it takes time and labor to use the CMM, which reduces the productivity.
The surface inspection tool and method of the present invention can solve the above problems, so that an inspector can judge whether scratches of a surface are located in a critical area on-line without using a CMM, thereby eliminating the above disadvantages.
The following description will be made by taking the mating surface between the cylinder head 4 and the cylinder head cover 5 as an example. On the mating surface of the cylinder head 4 with the head cover 5 (the upper surface of the cylinder head 4 in fig. 1, 2), the critical area is the surface that overlaps the head gasket 6 between the cylinder head 4 and the head cover 5, or the contour and position of the critical area of the upper surface of the cylinder head 4 coincide with the contour and position of the head gasket 6.
Fig. 3 shows a plan view of the head gasket 6. Fig. 4 shows a top view of the cylinder head 4, wherein the dashed lines indicate critical areas 10 of the upper surface 11 of the cylinder head 4, within which critical areas 10 no scratches can occur. Fig. 5 shows a perspective view of the cylinder head 4. Fig. 6 shows a surface inspection tool 16 of the present invention with an inspection area 15 marked thereon corresponding to the critical area 10.
The surface inspection tool 16 of the present invention includes a body made of a transparent material, such as acrylic, or other transparent material, preferably having a lower hardness than the part to be inspected, to avoid the creation of new scratches during the inspection process. As shown in fig. 6, the protruding portion 14 of the surface inspection tool 16 corresponds to the recessed portion 12 of the surface 11 of the cylinder head 4, and the plurality of openings 18 of the surface inspection tool 16 correspond to the plurality of protrusions 19 of the cylinder head 4, so that the surface inspection tool 16 can be placed on the upper surface 11 of the cylinder head 4 in a surface-to-surface manner.
As shown in fig. 6, the surface inspection tool 16 has an inspection area 15, which, as mentioned above, corresponds to the critical area 10 of the upper surface 11 of the cylinder head 4. Therefore, after the surface inspection tool 16 is seated on the upper surface 11 of the cylinder head 4, the inspector can directly and visually judge whether the scratches on the upper surface 11 of the cylinder head 4 are located in the critical area 10, so that the inspector can evaluate the scratches on line without carrying the entire cylinder head 4 to a constant temperature room in which CMM is stored for measurement.
In order to fix the position and prevent misalignment of the surface inspection tool 16 after it is placed on the upper surface 11 of the cylinder head 4, positioning pins 13, 17 are provided on the surface inspection tool 16, which correspond to two holes 20, 21, respectively, in the cylinder head 4, preferably the holes 20, 21 are holes inherent in the upper surface of the cylinder head 4, for the cylinder head 4 to cooperate with protruding parts of the cylinder head cover when the cylinder head 4 is assembled with the cylinder head cover 5. Preferably, the pins 13 may be provided as diamond-shaped pins. The positioning pins 13, 17 prevent any rattling of the surface inspection tool 16 on the upper surface 11 of the cylinder head 4, thereby fixing the position of the surface inspection tool 16.
To facilitate the inspection personnel's handling of the surface inspection tool 16, a handle 22 (shown in part in FIG. 6) is provided on the surface inspection tool. Preferably, the handle 22 is provided on the side of the surface inspection tool 16 opposite to the side resting on the upper surface 11 of the cylinder head 4. The handle 22 is mounted to the inspection tool body 16 by screws.
Preferably, at least one small hole is provided on the surface inspection tool 16, in which a rubber block 23 (see fig. 6) is mounted, said rubber block 23 being slightly protruded on the side in contact with the upper surface 11 of the cylinder head 4, and functioning to prevent the surface inspection tool 16 from directly contacting the upper surface 11 of the cylinder head 4 and colliding with the upper surface 11 of the cylinder head 4.
Preferably, in the area where the curve defining the inspection area 15 does not pass, if there is a height difference between the surface inspection tool 16 and the upper surface 11 of the cylinder head 4, a spacer 24 may be provided to compensate for the height difference. The spacer 24 may be opaque and mounted by screws to the body of the surface inspection tool 16. In the area where the curve defining the examination area 15 passes, a separate protruding part 14 is provided, which protruding part 14 is also made of acrylic material and can be mounted on a flat acrylic plate with screws.
It should be noted that different critical areas exist on different surfaces of different components, and therefore different surface inspection tools need to be provided for different surfaces of different components. For example, in an engine assembly plant, there are typically twenty or more surface inspection tools.
The surface inspection tool may be manufactured by molding or machining. The examination area 15 is defined by lines engraved by the engraving machine.
The present invention also provides a surface inspection method, which will be described below by taking the mating surface between the cylinder head 4 and the cylinder head cover 5 as an example.
First, a surface inspection tool 16 is provided, which is made of a transparent material, has a shape corresponding to the upper surface 11 of the cylinder head 4, and has a contour matching the upper surface 11 so that the surface inspection tool 16 can be placed on the upper surface 11 in a surface-to-surface manner. The inspection tool 16 is also marked with inspection areas 15 corresponding to the critical areas 10 of the upper surface.
Then, whether the scratch on the upper surface 11 of the cylinder head 4 is located within the inspection area 15 is visually observed on-line by an inspector, thereby judging whether the scratch is located within the critical area 10 on the upper surface 11 of the cylinder head 4.
Preferably, the inspection tool 16 has two locating pins 13, 17, one of which 13 is a diamond pin, so as to fix the position of the surface inspection tool 16, preventing any positional misalignment of the surface inspection tool 16 on the upper surface 11 of the cylinder head 4.
Preferably, a handle is provided on the surface inspection tool to facilitate the inspection personnel holding the surface inspection tool 16. Preferably, the handle is provided on the side of the surface inspection tool 16 opposite to the side resting on the upper surface 11 of the cylinder head 4.
Preferably, at least one small hole is provided on the surface inspection tool 16, in which a rubber block 23 is mounted, said rubber block 23 being slightly protruded on the side in contact with the upper surface 11 of the cylinder head 4, and serving to prevent the surface inspection tool 16 from directly contacting the upper surface 11 of the cylinder head 4 and from colliding with the upper surface 11 of the cylinder head 4. In another embodiment, the rubber block 23 may be directly adhered to the side of the surface inspection tool that contacts the upper surface 11 of the cylinder head 4.
Preferably, in the area where the curve defining the inspection area 15 does not pass, if there is a height difference between the surface inspection tool 16 and the upper surface 11 of the cylinder head 4, a spacer 24 may be provided to compensate for the height difference. The spacer 24 may be opaque and mounted by screws to the body of the surface inspection tool 16. In the area where the curve defining the inspection area 15 passes, a separate protruding portion 14 is provided, the shape of the protruding portion 14 does not interrupt the inspection area 15, and is transparent and can be mounted on the acrylic plate with screws.
Also, for different surfaces to be inspected of different parts, different surface inspection tools are provided, on which inspection areas corresponding to critical areas of the surface to be inspected are marked. The surface inspection method has universality, can be widely applied to the inspection of the key area of the surface to be inspected, and only different surface inspection tools need to be manufactured for different surfaces to be inspected, and the inspection areas corresponding to the key area of the surface to be inspected are marked on the inspection tools.
The surface inspection tool and method of the present invention have the advantages of: the whole surface to be inspected can be inspected by one tool at the same time, no matter whether the surface to be inspected is positioned in the same plane or not; the inspector can judge whether the scratch is in the key area by eyes on line without using devices such as a CMM (coordinate measuring machine) and the like, thereby improving the production efficiency.
