[0039] Figure 1 A schematic diagram of the structure of a cylinder head measuring device provided by an embodiment of the utility model, Figure 2 A schematic diagram of a cylinder head measuring device provided by an embodiment of the utility model at a viewing angle, as shown in FIG. Figure 1 and Figure 2As shown, the embodiment of the utility model provides a cylinder head measuring device 100, which is used to measure the size of each opening on the top surface and the bottom surface of the cylinder head 10. The cylinder head measuring device 100 includes: a measuring table 1, including a working surface 11, and the working surface 11 is divided into a first area 111, a middle area 113 and a second area 112 in sequence along its width direction; a mounting frame 12, which is arranged in the middle area 113, and the mounting frame 12 is used to mount the cylinder head 10 so that the top surface of the cylinder head 10 faces the first area 111 and the bottom surface of the cylinder head 10 faces the second area 112; a top surface measuring device 100, which is used to measure the size of each opening on the top surface and the bottom surface of the cylinder head 10. The measuring mechanism 2 is arranged in the first area 111, and is used to measure the size of the opening on the top surface of the cylinder head 10; the bottom surface measuring mechanism 3 is arranged in the second area 112, and is used to measure the size of the opening on the bottom surface of the cylinder head 10; the first moving mechanism 4 is used to drive the top surface measuring mechanism 2 to move along the length direction of the working surface 11, and the first moving mechanism 4 is installed in the first area 111; and the second moving mechanism 5 is used to drive the bottom surface measuring mechanism 3 to move along the length direction of the working surface 11; the second moving mechanism 5 is installed in the second area 112.

[0040] refer to Figure 1 and Figure 2 The measuring platform 1 further includes a bracket 14, and a side of the measuring platform 1 facing away from the working surface 11 is connected to the top of the bracket 14. A plurality of rollers 13 may be provided at the bottom of the bracket 14 to facilitate the overall movement of the cylinder head measuring device 100, thereby increasing the application scenarios of the cylinder head measuring device 100. The rollers 13 may be evenly distributed at the bottom of the bracket 14, and the rollers 13 may be universal wheels with a locking function, so as to facilitate the pushing of the cylinder head measuring device 100 while maintaining the stability of the cylinder head measuring device 100 during the test.

[0041] In this embodiment, before measuring the cylinder head 10, the cylinder head 10 is first installed on the mounting frame 12, with the top surface of the cylinder head 10 facing the first area 111 and the bottom surface facing the second area 112, and the preparation work is completed; during measurement, the positions of the top surface measuring mechanism 2 and the bottom surface measuring mechanism 3 are adjusted by the first moving mechanism 4 and the second moving mechanism 5, so that the top surface measuring mechanism 2 corresponds to the top surface of the cylinder head 10, and the bottom surface measuring mechanism 3 corresponds to the bottom surface of the cylinder head 10, thereby realizing the measurement of the sizes of the openings on the top and bottom surfaces of the cylinder head 10.

[0042] Therefore, this arrangement does not require frequent movement of the cylinder head 10. Only the first movable mechanism 4 and the second movable mechanism 5 need to be manipulated to achieve simultaneous measurement of the openings on the top and bottom surfaces of the cylinder head 10. Due to the arrangement of the mounting frame 12, the top surface of the cylinder head 10 faces the first area 111 and the bottom surface faces the second area 112, that is, the top and bottom surfaces of the cylinder head 10 become the “left” and “right” during measurement, which makes operation more convenient and measurement efficiency high.

[0043] like Figure 1 As shown, according to an optional embodiment of the utility model, the first moving mechanism 4 includes: a first guide rail 41 extending along the length direction of the working surface 11, and the top surface measurement mechanism 2 is slidably arranged on the first guide rail 41; and a first driving assembly connected to the top surface measurement mechanism 2, and used to drive the top surface measurement mechanism 2 to move along the extension direction of the first guide rail 41. The second moving mechanism 5 includes: a second guide rail 51 extending along the length direction of the working surface 11, and the bottom surface measurement mechanism 3 is slidably arranged on the second guide rail 51; and a second driving assembly connected to the bottom surface measurement mechanism 3, and used to drive the bottom surface measurement mechanism 3 to move along the extension direction of the second guide rail 51.

[0044] In this embodiment, the arrangement of the first drive assembly and the second drive assembly can conveniently realize the movement of the top surface measuring mechanism 2 and the bottom surface measuring mechanism 3 along the length direction of the working surface 11, thereby more conveniently realizing the alignment of the top surface measuring mechanism 2 and the bottom surface measuring mechanism 3 with the openings on the top surface and the bottom surface of the cylinder head 10, respectively, so as to measure the size of the openings.

[0045] Among them, the first drive component and the second drive component can both include a motor and a conveyor belt. The motor drives the conveyor belt installed on the first guide rail 41 (or the second guide rail 51) to drive the top surface measurement mechanism 2 (or the bottom surface measurement mechanism 3) fixedly connected to the conveyor belt to move.

[0046] In addition, the first driving assembly may include: a first lead screw, both ends of which are rotatably connected to both ends of the first guide rail 41; a first slider, which cooperates with the first lead screw and is fixedly connected to the top surface measurement mechanism 2; and a first motor, which is used to drive the first lead screw to rotate around its own axis to drive the first slider to move along the extension direction of the first lead screw. When driving, the first motor is started to rotate the first lead screw, and the slider moves along the extension direction of the first lead screw, so that the first slider drives the top surface measurement mechanism 2 to move along the extension direction of the first lead screw; the output shaft of the first motor should be coaxially connected to the first lead screw, and the top surface measurement mechanism 2 can be reciprocated along the extension direction of the first lead screw through the forward or reverse rotation of the output shaft.

[0047] Similarly, the second driving component includes: a second lead screw, whose two ends are respectively rotatably connected to the two ends of the second guide rail 51; a second slider, which cooperates with the second lead screw and is fixedly connected to the bottom surface measuring mechanism 3; and a second motor, which is used to drive the second lead screw to rotate around its own axis to drive the second slider to move along the extension direction of the second lead screw. The driving method of the second driving component to drive the bottom surface measuring mechanism 3 is the same as the driving method of the first driving component to drive the top surface measuring mechanism 2, which will not be repeated here.

[0048] It should be noted that the driving form of the first driving component and the second driving component is not limited to the conveyor belt drive and the screw drive. This embodiment is only used as an example to illustrate that the top surface measuring mechanism 2 and the bottom surface measuring mechanism 3 can be moved along the length direction of the working surface 11. The specific requirements can be determined according to the actual working conditions.

[0049] Figure 3 This is a schematic diagram of the structure of the top surface detection mechanism in the cylinder head measuring device provided by the embodiment of the utility model, referring to Figure 1-Figure 3 According to an optional embodiment of the utility model, the top surface measurement mechanism 2 includes a first body 21 and a first probe 22 installed on the first body 21, the first moving mechanism 4 is connected to the first body 21, and the first probe 22 is used to contact the opening on the top surface of the cylinder head 10 and measure the size of the opening on the top surface of the cylinder head 10. The top surface measurement mechanism 2 also includes a first driving member and a first guide member 23, the first guide member 23 extends along the width direction of the working surface 11, the first body 21 is slidably disposed on the first guide member 23, the first driving member is connected to the first body 21, and the first driving member is used to drive the first body 21 and the first probe 22 to move along the extension direction of the first guide member 23.

[0050] Among them, the measurement method of the first probe 22 is explained: the size of the first probe 22 is set relative to the size of the opening on the top surface of the cylinder head 10. Taking the first probe 22 as the standard, the standard size is compared with the actual size of the opening on the top surface of the cylinder head 10 to measure whether the size of the opening meets the standard; specifically, the first probe 22 includes a plurality of circumferentially distributed measuring points, for example, three circumferentially distributed measuring points can be set, and the radius of the circle passing through the three measuring points is fixed, which is the standard size; when measuring, if the three measuring points are all in contact with the inner wall of the measured opening, it means that the size of the opening meets the standard, and if at least one measuring point is not in contact with the inner wall of the measured opening, it means that the size of the opening does not meet the standard. It should be noted that here, only the first probe 22 includes three measuring points for example. Under actual working conditions, more measuring points can be set, which is based on actual needs, and the number of measuring points is not specifically limited.

[0051] In addition, each top surface measurement mechanism 2 may include a plurality of first probes 22 arranged at intervals to achieve simultaneous measurement of the sizes of a plurality of openings on the top surface of the cylinder head 10 ; the plurality of first probes 22 should be arranged one-to-one corresponding to the openings on the top surface of the cylinder head 10 .

[0052] In addition, the first driving member can be a first driving motor, the first guide member 23 can be a first guide rail, and the top surface measuring mechanism 2 is installed on the first guide rail through a sliding member. When the position of the top surface measuring mechanism 2 needs to be adjusted along the width direction of the working surface 11, the first driving motor is started to move the sliding member along the first guide rail. The operation is simple and convenient.

[0053] It should be noted that the specific structure of the first driving member and the first guide member 23 is not limited. This embodiment is only an example. It only needs to enable the top surface measurement mechanism 2 to move in the width direction of the working surface 11. The specific structure can be determined according to the actual working conditions.

[0054] In this embodiment, after the cylinder head 10 is installed on the mounting frame 12, the position of the top surface measuring mechanism 2 in the length direction of the working surface 11 relative to the opening on the top surface of the cylinder head 10 is adjusted by the first moving mechanism 4, and the position of the top surface measuring mechanism 2 in the width direction of the working surface 11 relative to the opening on the top surface of the cylinder head 10 is adjusted by the first driving member, so that the first probe 22 of the top surface measuring mechanism 2 corresponds to the opening on the top surface of the cylinder head 10, so as to measure the size of each opening on the top surface of the cylinder head 10.

[0055] like Figure 1 As shown, according to an optional embodiment of the present utility model, the middle area 113 is further provided with a first calibration mechanism 6 and a first cleaning mechanism 7 , the first calibration mechanism 6 is used to calibrate the measurement accuracy of the first measuring head 22 , and the first cleaning mechanism 7 is used to clean the first measuring head 22 .

[0056] In this embodiment, the use of the first calibration mechanism 6 and the first cleaning mechanism 7 is described by taking the first measuring head 22 including three circumferentially distributed measuring points as an example:

[0057] First, before measuring the size of the opening on the top surface of the cylinder head 10, the first probe 22 needs to be calibrated; for example, if the standard radius of the opening to be detected is 5 mm, the first calibration mechanism 6 should be provided with a first standard hole with a radius of 5 mm. During calibration, the first moving mechanism 4 and the first driving member are also used to achieve the correspondence between the first probe 22 and the first standard hole. If the three measuring points are all in contact with the inner wall of the first standard hole, it means that the radius of the circle surrounded by the three circumferentially distributed measuring points of the first probe 22 is 5 mm, which meets the measurement standard. If at least one measuring point does not fit the inner wall of the first standard hole, it means that the first probe 22 does not meet the measurement standard, and the relative positions of the three measuring points need to be readjusted. It should be noted that when there are multiple first probes 22, the first calibration mechanism 6 can also be provided with multiple first standard holes, and the multiple first probes 22 are arranged in a one-to-one correspondence with the multiple first standard holes.

[0058] In addition, the first cleaning mechanism 7 may include a first cleaning box and a first blowing nozzle located in the first cleaning box. When the opening on the top surface of the cylinder head 10 is inspected, the correspondence between the first measuring head 22 and the first blowing nozzle is also achieved through the first moving mechanism 4 and the first driving member. The first blowing nozzle blows air to the first measuring head 22 to remove impurities on the first measuring head 22, thereby ensuring the service life of the first measuring head 22 to a certain extent.

[0059] Figure 4 This is a schematic diagram of the structure of the bottom surface detection mechanism of the cylinder head measuring device provided by the embodiment of the utility model, referring to Figure 1 , Figure 2 and Figure 4 According to an optional embodiment of the utility model, the bottom surface measuring mechanism 3 includes a second body 31 and a second probe 32 installed on the second body 31, the second moving mechanism 5 is connected to the second body 31, and the second probe 32 is used to contact the opening on the bottom surface of the cylinder head 10 and measure the size of the opening on the bottom surface of the cylinder head 10. The bottom surface measuring mechanism 3 also includes a second driving member and a second guide member 33, the second guide member 33 extends along the width direction of the working surface 11, the second body 31 is slidably disposed on the second guide member 33, the second driving member is connected to the second body 31, and the second driving member is used to drive the second body 31 and the second probe 32 to move along the extension direction of the second guide member 33.

[0060] Among them, the measurement method of the second probe 32 is explained: the size of the second probe 32 is set relative to the size of the opening on the bottom surface of the cylinder head 10. Taking the second probe 32 as the standard, the standard size is compared with the actual size of the opening on the bottom surface of the cylinder head 10 to measure whether the size of the opening meets the standard; specifically, the second probe 32 includes a plurality of circumferentially distributed measuring points, for example, three circumferentially distributed measuring points can be set, and the radius of the circle passing through the three measuring points is fixed and is the standard size; during measurement, if the three measuring points are all in contact with the inner wall of the measured opening, it means that the size of the opening meets the standard, and if at least one measuring point is not in contact with the inner wall of the measured opening, it means that the size of the opening does not meet the standard. It should be noted that here, only the second probe 32 includes three measuring points for example. Under actual working conditions, more measuring points can be set, which is based on actual needs, and the number of measuring points is not specifically limited.

[0061] In addition, each bottom surface measuring mechanism 3 may include a plurality of second probes 32 arranged at intervals to achieve simultaneous measurement of the sizes of a plurality of openings on the bottom surface of the cylinder head 10 ; the plurality of second probes 32 should be arranged one-to-one corresponding to the openings on the bottom surface of the cylinder head 10 .

[0062] In addition, the second driving member can be a second driving motor, the second guide member 33 can be a second guide rail, and the bottom surface measuring mechanism 3 is installed on the second guide rail through a sliding member. When it is necessary to adjust the position of the bottom surface measuring mechanism 3 along the width direction of the working surface 11, start the second driving motor to move the sliding member along the second guide rail. The operation is simple and convenient.

[0063] It should be noted that the specific structure of the second driving member and the second guide member 33 is not limited. This embodiment is only an example. It only needs to enable the bottom surface measuring mechanism 3 to move in the width direction of the working surface 11. The specific structure can be determined according to the actual working conditions.

[0064] In this embodiment, after the cylinder head 10 is installed on the mounting frame 12, the second moving mechanism 5 is used to adjust the position of the bottom surface measuring mechanism 3 relative to the openings on the bottom surface of the cylinder head 10 in the length direction of the working surface 11, and the second driving member is used to adjust the position of the bottom surface measuring mechanism 3 relative to the openings on the bottom surface of the cylinder head 10 in the width direction of the working surface 11, so that the second probe 32 of the bottom surface measuring mechanism 3 corresponds to the openings on the bottom surface of the cylinder head 10, so as to measure the sizes of the openings on the bottom surface of the cylinder head 10.

[0065] like Figure 1 As shown, according to an optional embodiment of the present utility model, the middle area 113 is further provided with a second calibration mechanism 8 and a second cleaning mechanism 9 , the second calibration mechanism 8 is used to calibrate the measurement accuracy of the second probe 32 , and the second cleaning mechanism 9 is used to clean the second probe 32 .

[0066] In this embodiment, the use of the second calibration mechanism 8 and the second cleaning mechanism 9 is described by taking the second measuring head 32 including three circumferentially distributed measuring points as an example:

[0067] First, before measuring the size of the opening on the bottom surface of the cylinder head 10, the second probe 32 needs to be calibrated first; for example, if the standard radius of the opening to be detected is 5 mm, then the second calibration mechanism 8 should be provided with a second standard hole with a radius of 5 mm. During calibration, the second probe 32 and the second standard hole are also matched by the second moving mechanism 5 and the second driving member. If the three measuring points are all in contact with the inner wall of the second standard hole, it means that the radius of the circle surrounded by the three circumferentially distributed measuring points of the second probe 32 is 5 mm, which meets the measurement standard. If at least one measuring point does not fit the inner wall of the second standard hole, it means that the second probe 32 does not meet the measurement standard, and the relative positions of the three measuring points need to be readjusted. It should be noted that when there are multiple second probes 32, the second calibration mechanism 8 can also be provided with multiple second standard holes, and the multiple second probes 32 are set in one-to-one correspondence with the multiple second standard holes.

[0068] In addition, the second cleaning mechanism 9 may include a second cleaning box and a second blowing nozzle located in the second cleaning box. After the opening on the bottom surface of the cylinder head 10 is inspected, the second moving mechanism 5 and the second driving member are also used to achieve the correspondence between the second measuring head 32 and the second blowing nozzle. The second blowing nozzle blows air to the second measuring head 32 to remove impurities on the second measuring head 32, thereby ensuring the service life of the second measuring head 32 to a certain extent.

[0069] According to an optional embodiment of the present utility model, there are multiple top surface measurement mechanisms 2 and multiple bottom surface measurement mechanisms 3.

[0070] In addition to the above-mentioned method in which the top surface measuring mechanism 2 includes multiple first probes 22 and the bottom surface measuring mechanism 3 includes multiple second probes 32, the present embodiment also provides a method in which both the top surface measuring mechanism 2 and the bottom surface measuring mechanism 3 (hereinafter collectively referred to as measuring mechanisms) are multiple. The purpose of these two schemes is to provide more first probes 22 and second probes 32 (hereinafter collectively referred to as probes) to further improve the efficiency of measuring the dimensions of the openings on the bottom and top surfaces of the cylinder head 10. As to whether one measuring mechanism includes multiple probes or the cylinder head measuring device 100 includes multiple measuring mechanisms, it depends on actual needs and is not specifically limited.
