In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0039] When using a digital dial indicator to measure parameters such as the flatness or scratch depth of the surface of the part to be tested at the production site, a circular sleeve is usually used to clamp and fix the digital dial indicator, and the circular sleeve is placed on the part to be measured. However, the circular sleeve cannot stably contact the part to be measured, making the circular sleeve prone to shaking, reducing the measurement accuracy of the digital dial indicator, and it also takes a lot of time to adjust the placement of the circular sleeve, which greatly increases the measurement time. In addition, if there are large pits on the surface of the part to be measured, the circular sleeve cannot be placed firmly on the part to be measured, greatly reducing the application scenarios of the circular sleeve.

[0040] In order to solve the above problems, Figure 1 to Figure 4As shown, this embodiment provides a measuring clamping device, which includes a mounting tube 1 and a support assembly 2, wherein the mounting tube 1 is used to sleeve and fix the measuring piece, the support assembly 2 is used to be placed on the piece to be measured, the support assembly 2 is installed on the mounting tube 1, and the installation position of the support assembly 2 and the mounting tube 1 is adjustable along the radial direction of the mounting tube 1. The measuring clamping device provided in this embodiment realizes the stable placement of the measuring clamping device on the piece to be measured by arranging the support assembly 2 on the mounting tube 1, improves the stability of clamping and fixing the measuring piece, ensures the measurement accuracy of the measuring piece to the piece to be measured, and does not need to repeatedly adjust the placement position of the support assembly 2 on the piece to be measured, saving the time for measurement. In addition, since the installation position of the support assembly 2 and the mounting tube 1 is adjustable along the radial direction of the mounting tube 1, even if there is a large pit on the piece to be measured, the support assembly 2 can avoid the pit position to realize the stable placement of the support assembly 2 on the piece to be measured, effectively improving the applicable scenarios of the measuring clamping device.

[0041] Optionally, in this embodiment, the measuring piece can be a digital dial indicator, and the digital dial indicator is fixed in the center hole 12 of the mounting tube 1, and one end of the digital dial indicator extending from the center hole 12 is used to fit the piece to be measured, so as to measure the flatness or scratch depth of the surface of the piece to be measured. Optionally, in this embodiment, the piece to be measured can be a structure with a high degree of curvature, such as an aircraft flap or a pipeline.

[0042] Optionally, in this embodiment, the support assembly 2 includes two support feet 21 arranged opposite to each other along the radial direction of the mounting tube 1, and the support feet 21 are used to be placed on the object to be measured, and the installation position of each support foot 21 and the mounting tube 1 is adjustable along the radial direction of the mounting tube 1. By providing two support feet 21 to support the entire measuring clamping device, the stability of the measuring clamping device placed on the object to be measured is further improved. It should be noted that, if Figure 1 As shown, in general use scenarios, the support legs 21 can be installed closely to the installation tube 1, so that the distance between the two support legs 21 is minimized to ensure the stability of the support legs 21 installed and fixed on the installation tube 1. Figure 2 As shown, when there are large pits on the surface of the workpiece to be measured or the support feet 21 with the current spacing cannot achieve stable placement on the workpiece to be measured, the installation positions of the support feet 21 and the mounting tube 1 along the radial direction of the mounting tube 1 can be adjusted to increase the spacing between the two support feet 21 to ensure that the support feet 21 avoid the pit position to achieve stable placement of the support assembly 2 on the workpiece to be measured.

[0043] In this embodiment, a mounting groove 11 is provided on the side of the mounting tube 1 facing the supporting foot 21. The supporting foot 21 includes a mounting portion 211, which is mounted in the mounting groove 11, and the shape of the mounting groove 11 is adapted to the outer contour of the mounting portion 211 in the mounting groove 11. The above arrangement enables the mounting portion 211 to be tightly fitted in the mounting groove 11 when the supporting foot 21 is tightly fitted with the mounting tube 1, effectively increasing the mounting area of ​​the mounting portion 211 and the mounting groove 11, and improving the stability and reliability of the mounting portion 211 and the mounting tube 1.

[0044] In this embodiment, the measuring clamping device further includes a connecting component 3, which is screwed through the supporting foot 21 and then threadedly connected to the mounting tube 1, and the screwing depth of the connecting component 3 in the mounting tube 1 is adjustable. By adjusting the screwing depth of the connecting component 3 in the mounting tube 1, the installation position of the supporting foot 21 and the mounting tube 1 along the radial direction of the mounting tube 1 is adjusted, so that the structure is simple and the adjustment is convenient.

[0045] Optionally, in this embodiment, if Figure 2 As shown, the connecting assembly 3 includes a connecting bolt 31 and at least one adjusting gasket 32, wherein the connecting bolt 31 is screwed through the supporting foot 21 and then threadedly connected to the mounting tube 1, at least one adjusting gasket 32 ​​is sleeved on the connecting bolt 31, and at least one adjusting gasket 32 ​​is clamped between the mounting tube 1 and the supporting foot 21. By providing the adjusting gasket 32, the tightness of the connection between the supporting foot 21 and the mounting tube 1 by the connecting assembly 3 is effectively improved. It should be noted that by adjusting the number of adjusting gaskets 32 used, the screwing depth of the connecting bolt 31 in the mounting tube 1 is adjusted, and then the installation position of the supporting foot 21 is adjusted, so that the structure is simpler and more reliable. It should be noted that, as Figure 1 As shown, when the support legs 21 are tightly fitted with the mounting grooves 11 of the mounting tube 1 , the adjustment gaskets 32 may not be used, and the more adjustment gaskets 32 are used, the larger the distance between the two support legs 21 is.

[0046] Optionally, in this embodiment, the adjusting gasket 32 ​​is an elastic gasket. By designing the adjusting gasket 32 ​​as an elastic gasket, the tightness and reliability of the installation of the supporting foot 21 and the installation tube 1 are further guaranteed. Specifically, the adjusting gasket 32 ​​can be a rubber gasket.

[0049] Optionally, in the present embodiment, the fixing assembly 4 includes a fixing bolt 41 and an abutting washer 42, wherein the fixing bolt 41 is threadedly connected to the mounting tube 1 and then extends into the center hole 12 in the mounting tube 1, the abutting washer 42 is located in the center hole 12 in the mounting tube 1, and the abutting washer 42 is sandwiched between one end of the fixing bolt 41 extending into the center hole 12 and the measuring piece. By providing the abutting washer 42, not only the abutting fixation of the measuring piece in the center hole 12 is achieved, but also the abutting damage to the measuring piece is avoided, thereby improving the protection of the measuring piece. Optionally, in other embodiments, the abutting washer 42 may not be provided, so that one end of the fixing bolt 41 extending into the center hole 12 directly abuts against the measuring piece. Specifically, a third mounting hole 13 connected to the center hole 12 is provided on the wall of the mounting tube 1, and the fixing bolt 41 is screwed through the third mounting hole 13 and then extends into the center hole 12.

[0050] Optionally, in this embodiment, the abutment washer 42 may be a spring washer. By designing the abutment washer 42 as a spring washer, elastic abutment and fixation of the measuring piece is achieved, further improving the protection of the measuring piece. Optionally, when the diameter of the rod portion of the measuring piece extending into the center hole 12 changes, a spring washer of appropriate thickness may be selected according to the diameter of the rod portion to abut and fix the measuring piece.

[0051] In order to facilitate understanding of the measurement clamping device disclosed in this embodiment, Figure 1 to Figure 4 The specific use process of the measuring clamping device is described as follows:
