[0027] Please check again. Figures 1 to 3 The measuring assembly 30 further includes a support 43, a pin 44, a linkage 45, and a wrench 46. The support 43 is mounted on the base 10, and the pin 44 passes through the support 43. One end of the pin 44 is used to abut against the end of the slide plate 33 away from the second top post 32. One end of the linkage 45 is pivotally connected to the support 43, and one end of the wrench 46 is pivotally connected to the linkage 45, while the other end is pivotally connected to the end of the pin 44 away from the slide plate 33. By turning the wrench 46 around the linkage 45, the pin 44 is moved closer to or away from the slide plate 33. In one embodiment, the measuring assembly 30 further includes a support column 47 and a mounting base 48. The support column 47 is mounted on the fixed plate 37 and is used to abut against the contact end of the measuring instrument 36. The mounting base 48 is mounted on the base 10, and the measuring instrument 36 is mounted on the mounting base 48.

[0028] like Figure 1 and Figure 2 As shown, the high-precision hardware component inner diameter detection device 100 also includes a limiting plate 50, which is installed on one side of the support plate 20 and is used to abut against the outer side of the high-precision hardware component 90. Optionally, the limiting plate 50 is movably connected to the support plate 20 to adjust its position and adapt to products of different specifications. In one embodiment, the high-precision hardware component 90 is a hollow cylindrical tube. When the outer side of the high-precision hardware component 90 abuts against one side of the limiting plate 50, the straight line containing the first top post 31 and the second top post 32 is collinear with the diameter of the cylindrical tube.

[0029] like Figure 1 and Figure 2 As shown, the high-precision hardware internal diameter detection device 100 also includes a lifting assembly 60. The lifting assembly 60 includes a guide block 61, a lifting column 62, and a fastener 63. The guide block 61 is installed on the base 10. One end of the lifting column 62 is installed on the support plate 20, and the other end passes through the guide block 61. The fastener 63 is used to fix the lifting column 62 and the guide block 61. The height of the support plate 20 can be adjusted by sliding the lifting column 62 on the guide block 61. In one embodiment, the lifting assembly 60 also includes a positioning block 64. The positioning block 64 is installed at the end of the lifting column 62 away from the support plate 20 to limit the position of the lifting column 62 and prevent the lifting column 62 from disengaging from the guide block 61. Optionally, there are multiple guide blocks 61, lifting columns 62, fasteners 63, and positioning blocks 64, and they correspond one-to-one.

[0030] In one embodiment, the lifting assembly 60 further includes a rack 65, a support base 66, a rotating rod 67, a gear 68, and a gripper 69. The rack 65 is installed at the bottom of the support plate 20, the support base 66 is installed on the base 10, the rotating rod 67 is rotatably connected to the support base 66, the gear 68 and the gripper 69 are respectively installed at both ends of the rotating rod 67, and the gear 68 meshes with the rack 65. By rotating the rotating rod 67 in both directions through the gripper 69, the gear 68 is driven to rotate in both directions, thereby driving the rack 65 to rise and fall, thereby driving the support plate 20 to rise and fall. The distance between the first top post 31 and the support plate 20, and between the second top post 32 and the support plate 20, is adjusted so that the first top post 31 and the second top post 32 abut against different positions of the high-precision hardware 90, which is suitable for high-precision hardware 90 of different heights. When the height of the support plate 20 needs to be adjusted, loosen the fastener 63, rotate the lever 67 in both directions through the grip 69, thereby driving the gear 68 to rotate in both directions, which in turn drives the rack 65 to rise and fall, thereby driving the support plate 20 to rise and fall. Then tighten the fastener 63 to fix the lifting column 62 and the guide block 61.

[0031] In use, turn the wrench 46 to slide the pin 44 onto the support 43, causing the pin 44 to push the slide plate 33 towards the support plate 34, thereby moving the second top post 32 towards the first top post 31, so that the distance between the second top post 32 and the first top post 31 is less than the inner diameter of the high-precision hardware 90. Then place the high-precision hardware 90 on the bearing plate 20, so that the outer side of the high-precision hardware 90 abuts against the limiting plate 50, and the inner side of one end of the high-precision hardware 90 abuts against the first top post 31. Next, turn the wrench 46 in the opposite direction to move the pin 44 away from the slide plate 33. Under the action of the elastic element 35, the slide plate 33 slides towards the support 66, thereby moving the second top post 32 away from the first top post 31, so that the second top post 32 abuts against the inner side of one end of the high-precision hardware 90. At this time, the support column 47 abuts against the contact end of the measuring gauge 36, and the accuracy of the inner diameter is detected by the reading of the measuring gauge 36. This high-precision hardware inner diameter detection device 100 adjusts the position of the first top column 31 by adjusting the position of the first vertical plate 39 and the guide seat 38, and adjusts the position of the second top column 32 by adjusting the position of the second vertical plate 42 and the slide plate 33, thereby adjusting the distance between the first top column 31 and the second top column 32. It is suitable for high-precision hardware 90 with different inner diameters. By adjusting the height of the support plate 20, the height of the first top column 31 and the support plate 20, and the height of the second top column 32 and the support plate 20 are adjusted, thus making it suitable for high-precision hardware 90 with different heights and having a wide range of applications.

[0032] The high-precision hardware component inner diameter detection device 100 of this utility model slides the slide plate 33 towards the first top post 31, and then places the high-precision hardware component 90 on the support plate 20, with the inner side wall of the high-precision hardware component 90 abutting against the first top post 31. Then, the slide plate 33 is released, and under the action of the elastic member 35, the second top post 32 and the first top post 31 abut against the inner side wall of the high-precision hardware component 90 respectively. At this time, the fixing plate 37 abuts against the contact end of the measuring gauge 36, and the accuracy of the inner diameter is detected by the reading of the measuring gauge 36. The high-precision hardware component inner diameter detection device 100 is easy to use and applicable to high-precision hardware components 90 of different specifications.

[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
