[0020] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0021] See also Figure 1 , a schematic structural diagram of a vibration velocity sensor calibration tooling used on an excitation table in an embodiment of the utility model, which includes a mounting base 100, a column 200, an adapter plate 300, and a connecting assembly 400; the mounting base 100 includes a main mounting portion 110 and two side mounting portions 120 respectively located on both sides of the main mounting portion 110, the main mounting portion 110 is provided with a long hole 111 along a first direction, and a first mounting hole 121 is provided through the side mounting portion 120 in the first direction x; one end of the column 200 is connected to the first mounting hole 121, and the other end of the column 200 is used to connect to the excitation table; the adapter plate 300 is provided with a second mounting hole 310 and a third mounting hole 320 for connecting to the vibration velocity sensor 10; the connecting assembly 400 is detachably fixed to the second mounting hole 310 and the long hole 111 to lock the relative position of the adapter plate 300 and the mounting base 100 in the first direction x.

[0022] The vibration velocity sensor calibration tooling applied to the vibration table is provided with a mounting seat 100 and a column 200, an adapter plate 300, and a connecting assembly 400 that match the mounting seat 100, so as to realize the stable installation of the vibration velocity sensor 10. Specifically, the column 200 is fixed with the original mounting hole of the vibration table, and the installation position of the column 200 can be completely determined according to the original mounting hole position of the vibration table, and there is no mismatch. On the other hand, the column 200 increases the height of the vibration velocity sensor 10, and pulls the height of the vibration velocity sensor 10 and the vibration table apart for easy operation. In addition, the main body mounting part 110 is provided with a long hole 111 along the first direction, and the connecting assembly 400 has a certain degree of freedom in the first direction x, and the height, that is, the longitudinal position, can be adjusted. In this way, the longitudinal position of the vibration velocity sensor 10 can be adjusted, thereby improving the flexibility of the installation of the vibration velocity sensor 10, and can be adjusted according to needs, adapting to more scenes, and more convenient to operate.

[0023] It should be noted that the present embodiment does not use an integrated installation tool, but instead uses a combination of a mounting base 100, a column 200, and an adapter plate 300. This is not only convenient for storage and transportation, but also convenient for replacement and adjustment when a part of it cannot adapt to the working conditions, which can save costs to a certain extent.

[0024] In the specific configuration, the column 200 is configured as a threaded column to facilitate installation, fixing and disassembly. The thread size of one end of the column 200 is determined according to the original threaded hole of the excitation platform.

[0025] In one embodiment, the connection assembly 400 includes an adapter block screw 410 installed in the second installation hole 310, a first bolt 420 threadedly connected to the adapter block screw 410, and the first bolt 420 passes through the long hole 111 and is connected to the butterfly nut 430. In this arrangement, rotating the butterfly nut 430 is convenient for applying force and is relatively labor-saving.

[0026] In one embodiment, a slide groove 112 is formed on the main mounting portion 110 along the first direction x, a long hole 111 is formed on the bottom wall 1121 of the slide groove 112 , and the adapter plate 300 is at least partially embedded in the slide groove 112 and can move in the slide groove 112 along the first direction x.

[0027] In one embodiment, the sliding groove 112 has a first inner wall 1122 and a second inner wall 1123 facing each other.

[0028] On the basis of the above embodiment, the two sides of the adapter plate 300 are respectively attached to the first inner wall 1122 and the second inner wall 1123 to limit the position of the adapter plate 300 in the second direction y, and the second direction y is perpendicular to the first direction x. In this way, when the longitudinal position of the vibration velocity sensor 10 is adjusted, it can ensure that the vibration velocity sensor 10 moves in the first direction x to avoid tilting and causing the center position to shift.

[0029] In one embodiment, the main mounting portion 110 and the side mounting portions 120 on both sides are integrally formed.

[0030] In one embodiment, the mounting seat is in a U-shaped structure. It should be noted that the shape of the mounting seat is not limited, and it can also be set to an M shape, and the main mounting portion 110 is also set in the middle position, and the side mounting portions 120 are symmetrically arranged on both sides of the main mounting portion 110.

[0031] The steps for installing the vibration velocity sensor 10 are as follows:

[0032] Step S100, screw one end surface of the two columns 200 into the mounting hole of the excitation table, and then connect the mounting base 100 to the other end surface of the column 200 with an M5 bolt;

[0033] Step S200, then fix the adapter plate 300 to the adapter block screw 410 with M5 bolts;

[0034] Step S300, insert the adapter block screw 410 into the long hole 111, and lock it with the butterfly nut 430;

[0035] Step S400, connecting the vibration velocity sensor 10 to the adapter plate 300 with M5 bolts;

[0036] Step S500 , by adjusting the butterfly nut 430 , the adapter block screw 410 together with the vibration velocity sensor 10 moves up and down, and when reaching a suitable first direction position, the butterfly nut 430 is tightened.

[0037] It should be noted that since the center of the table top of the vibration table and the mounting hole of the table top are fixed, the probe of the vibration velocity sensor 10 is aligned with the center of the table top of the vibration table during design. Regarding the centering of the vibration velocity sensor 10, the lateral and axial dimensions have been taken into account in the overall structural dimensions and assembly tolerances of the tooling, but the vertical dimension, i.e. the first direction x dimension, needs to be relaxed to a certain extent to facilitate pressing the vibration velocity sensor 10 and adjusting the vertical x position, i.e. the first direction.

[0038] In another embodiment, the first mounting hole 121 is configured as a long hole extending along the second direction y, so that the column 200 has a certain degree of freedom in the second direction y to avoid failure to install when the distances between the two columns 200 are slightly different.
