Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0025] According to a first aspect of the present invention, a fixture for detecting the size of the seat ring conical surface is provided, such as... Figures 1 to 11 As shown, the fixture for measuring the cone surface dimension of the seat ring is used to measure the surface 601 (i.e., the cone surface) of the seat ring body 6. The seat ring body 6 is fitted with a seat ring guide (not shown). Both the seat ring body 6 and the seat ring guide can be common, existing components. The specifications and models of the seat ring body 6 and the seat ring guide may vary depending on the vehicle model being manufactured. The fixture for measuring the cone surface dimension of the seat ring includes a measuring guide post 1 and a dimensional gauge block.

[0026] In the following description, reference will be made to Figures 1 to 11 The detailed structure of the measuring guide post 1 and the fixed-size gauge block of the inspection fixture for measuring the cone surface dimension of the seat ring is described in detail.

[0027] like Figures 1 to 8 As shown, in the embodiment, the measuring guide post 1 includes at least a guide portion 101 that extends into the seat ring guide tube. The measuring guide post 1 can be formed into an approximately cylindrical structure, with one end of the cylindrical structure forming a guide portion 101 that can extend into the seat ring guide tube. The guide portion 101 can provide stable support for a fixed-size gauge block to facilitate the measurement of the seat ring body 6.

[0028] Furthermore, the dimensional gauge block may include a fitting portion 4 and a measuring portion 5. The dimensional gauge block is fitted onto the guide portion 101 through the fitting portion 4, and the measuring portion 5 extends outward from the edge of the fitting portion 4 to form a measuring surface 501. The measuring surface 501 can abut against the surface 601 to be measured of the seat body 6. To adapt to the annular shape of the seat body 6, the measuring surface 501 can be formed as an arc surface in the circumferential direction of the fitting portion 4. The dimensionality of the dimensional gauge block can be understood as follows: to correspond to the surface 601 to be measured of seat bodies 6 of different specifications, the tilt angle of the measuring surface 501 can be preset in advance, for example, as in the embodiment, such as... Figure 6 and Figure 8The 90° or 120° angle shown indicates that the measuring angle of the fixed-size gauge block fitted onto the guide part 101 is fixed, thereby enabling quick and convenient measurement of the surface 601 to be measured on the seat ring body 6. During measurement, the position of the fixed-size gauge block on the guide part 101 is adjusted so that the measuring surface 501 of the fixed-size gauge block is aligned with and fits the surface 601 to be measured on the seat ring body 6. If the fixed-size gauge block cannot fit completely or the size of the surface 601 to be measured is not within the set range, it indicates that the seat ring body 6 is not properly processed and requires secondary processing.

[0029] This fixture for measuring the conical surface dimensions of the cylinder head seat ring utilizes a measuring guide post 1 and a fixed-size gauge block. The gauge block can rotate and move up and down along the measuring guide post 1, enabling rapid measurement of the surface 601 of the cylinder head seat ring body 6. The entire measurement process does not require disassembly of the cylinder head seat ring body 6 or the use of complex measuring instruments, significantly reducing measurement time and allowing for real-time inspection during processing, effectively improving production efficiency. The measuring guide post 1 ensures the accurate positioning of the gauge block during measurement, avoiding errors caused by measurement position deviation. Furthermore, the gauge block is customized according to the standard depth dimensions of various angles of the cylinder head seat ring body 6, allowing direct judgment of dimensional compliance based on the fit between the gauge block and the surface 601 of the cylinder head seat ring body 6. The measurement accuracy meets the processing requirements of the cylinder head seat ring. The fixture has a simple overall structure; operators only need simple training to master the operation of rotating and moving the gauge block, requiring no specialized measurement skills, thus lowering the operational threshold and improving inspection efficiency.

[0030] Preferably, in the embodiment, since the specifications and models of the seat body 6 and the seat guide tube may vary depending on the vehicle model being manufactured, the diameter of the guide portion 101 should correspond to the inner diameter of the seat guide tube 6 of different specifications in order to accommodate seat body 6 and seat guide tube of different specifications.

[0031] Preferably, such as Figures 1 to 8 As shown in the embodiment, to accommodate the inspection of different specifications of cylinder head race body 6, the fitting part 4 of the fixed-size gauge block is detachably fitted onto the guide part 101. This means that the fixture for inspecting the cone surface size of the race can select different specifications of measuring guide post 1 and fixed-size gauge blocks according to different models of race body 6 and race guide tubes. The detachable connection design allows the fixture to be flexibly replaced according to the dimensions of different models of race body 6 and race guide tubes, making it suitable for measuring various specifications of cylinder head races and reducing equipment investment costs.

[0032] Preferably, such as Figures 1 to 8As shown in the embodiment, in order to realize the up-and-down movement and rotation of the fixed-size block, the guide part 101 is formed into a cylindrical structure, and a sleeve hole 401 is formed in the sleeve part 4. The diameter of the sleeve hole 401 is larger than the diameter of the cylindrical structure, so that the fixed-size block can move along the axial direction of the guide part 101 and can rotate along the circumferential direction of the guide part 101.

[0033] Preferably, such as Figures 5 to 8 As shown, in this embodiment, in order to correspond the measuring surface 501 of the fixed-size gauge block to the measuring surface 601 of the seat body 6, the measuring surface 501 is formed as an inclined surface. Since the seat body 6 may have multiple measuring surfaces 601 or different measuring positions, the seat conical surface dimension detection fixture may include multiple fixed-size gauge blocks, each fixed-size gauge block having a different inclination angle of its measuring surface 501.

[0034] Further, in the embodiment, the first fixed-size gauge block 2 and the second fixed-size gauge block 3 are respectively, wherein the tilt angle of the measuring surface 501 of the first fixed-size gauge block 2 is 90°, and the tilt angle of the measuring surface 501 of the second fixed-size gauge block 3 is 120°.

[0035] Preferably, such as Figures 1 to 8 As shown in the embodiment, in order to more intuitively set the standard range required for processing, and to more intuitively see whether the test surface 601 of the seat body 6 is within the standard range, the dimensional gauge block also includes a scale surface, on which a scale ruler 502 is provided, and the scale surface is located on the side of the measuring surface 501. Figure 11 As shown, if the standard size is set to four scale intervals, then at this time... Figure 11 The surface 601 of the seat body 6 to be measured is significantly smaller than the standard size. The difference on the scale 502 is the scale difference S, and the size that needs to be adjusted on the seat body 6 is the adjustment depth D.

[0036] Preferably, such as Figures 1 to 4 As shown, in this embodiment, the measuring guide post 1 may further include a limiting part 102, which is disposed opposite to the guide part 101. The limiting part 102 may be formed into a disc-shaped structure, and the size of the disc-shaped limiting part 102 is larger than the size of the sleeve hole 401 to prevent the fixed-size gauge block from coming out. Furthermore, for ease of storage, such as... Figure 2 As shown, the inner diameter of multiple fixed-size gauge blocks can be increased sequentially from top to bottom so that the multiple fixed-size gauge blocks can be nested with each other.

[0037] This fixture for measuring the conical surface dimensions of cylinder head seats utilizes a measuring guide post and a fixed-size gauge block. The gauge block rotates and moves up and down along the measuring guide post, enabling rapid measurement of the conical surface of the cylinder head seat. The entire measurement process does not require disassembly of the cylinder head seat or the use of complex measuring instruments, significantly reducing measurement time and allowing for real-time inspection during manufacturing, thus effectively improving production efficiency. The measuring guide post ensures the accurate positioning of the gauge block during measurement, avoiding errors caused by positional deviations. Furthermore, the gauge block is customized according to the standard depth dimensions of various angles on the cylinder head seat, allowing for direct judgment of dimensional compliance based on the fit between the gauge block and the conical surface of the cylinder head seat. The measurement accuracy meets the manufacturing requirements of cylinder head seat rings. The fixture has a simple overall structure; operators only need minimal training to master the operation of rotating and moving the gauge block, eliminating the need for specialized measurement skills and lowering the operational threshold while improving inspection efficiency.

[0038] Furthermore, according to a second aspect of the present invention, a detection method is provided, wherein the detection method uses a detection fixture to detect the test surface 601 of the seat ring body 6 using the seat ring cone surface size as described above.

[0039] The testing method includes: First, selecting a measuring guide post 1 of appropriate specifications according to the seat ring body 6 to be measured, so that the guide part 101 of the measuring guide post 1 can be inserted into the seat ring guide tube and remain stable; Second, selecting a fixed-size gauge block with a measuring surface 501 and height that matches the seat ring body 6 to be measured. The inclination of the measuring surface 501 of the fixed-size gauge block corresponds to the machining accuracy of the measuring surface 601 of the seat ring body 6, for example, 90° or 120° in the embodiment. The height of the fixed-size gauge block is set according to the standard depth dimension of the seat ring body 6 to be measured. The second step is to select an appropriate number of fixed-size gauge blocks according to the number of positions to be measured on the seat ring body 6, and to fit the fixed-size gauge blocks onto the measuring guide post 1 for measuring the cone surface size of the seat ring body 6; the guide part 101 of the measuring guide post 1 can be inserted into the seat ring guide tube to realize the guiding function in the measurement.

[0040] The third step is to adjust the position of the dimensional gauge block on the guide 101. Specifically, it can be moved up and down along the axial direction of the guide 101, or rotated circumferentially along the guide 101, so that the measuring surface 501 is aligned with and abuts against the test surface 601 of the seat ring body 6. Observe whether the dimension of the test surface 601 of the seat ring body 6 is within the set range of the dimensional gauge block. If it is, it indicates that the dimension of the seat ring body 6 is qualified; otherwise, secondary processing is required depending on the amount of deviation. Then, the secondary-processed seat ring body is measured again until it meets the processing standards. For details, see [link to documentation]. Figure 11Taking the inclination angle of the measuring surface 501 of the fixed-size gauge block as 90° as an example, Figure 11 The figure shown indicates that the size of the surface 601 to be measured on the seat body 6 is outside the set range. The difference on the scale 502 is the scale difference S. The size that needs to be adjusted on the seat body 6 is the adjustment depth D. The adjustment depth D = scale difference S × SIN45°.
