DETAILED DESCRIPTION

[0061] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Example 1

[0062] In order to solve the problem that the current instrument strength testing equipment cannot quickly limit and fix different types of instruments, please refer to Figure 1-6 The present invention provides the following technical solution: an instrument strength testing device for high-precision instrument production, comprising: a testing table 1, a fixing plate 2, a mounting plate 3, a sleeve rod 4, a first adjustment rod 5, a first cross bar 6, a second cross bar 7, a third cross bar 8, a bonding plate 9, a fixing bolt 10, a groove 11, a suction cup 12, a limit block 13, a slide groove 14, a slider 15 and a damping pad 16;

[0063] Among them, a fixing plate 2 is arranged above the testing platform 1, and a mounting plate 3 for limiting the high-precision instrument is installed above the fixing plate 2. The sleeve rod 4 is fixedly welded at the four corners of the top of the fixing plate 2, and the first adjusting rod 5 is rotatably installed at the four corners of the mounting plate 3. The bottom end of the first adjusting rod 5 is threadedly connected with the sleeve rod 4 in a one-to-one correspondence. The inner side of the mounting plate 3 is provided with a first cross bar 6, a second cross bar 7 and a third cross bar 8 for sliding back and forth. The tops of the first cross bar 6, the second cross bar 7 and the third cross bar 8 are all connected to the limiting mechanism, and the bottom surfaces of the ends of the first cross bar 6, the second cross bar 7 and the third cross bar 8 are integrated and convex outward. A bonding plate 9 is provided, and the first cross bar 6, the second cross bar 7 and the third cross bar 8 form a snap-fit ​​sliding structure between the bonding plate 9 and the mounting plate 3. Through grooves are provided inside the left and right sides of the mounting plate 3, and the ends of the first cross bar 6, the second cross bar 7 and the third cross bar 8 are connected with fixing bolts 10. The through-slots of the fixing bolts 10 are threadedly connected with the first cross bar 6, the second cross bar 7 and the third cross bar 8. The rear side surface of the first cross bar 6, the front side surface of the second cross bar 7 and the front and rear side surfaces of the third cross bar 8 are all provided with grooves 11 at equal intervals, and the inside of the grooves 11 is equipped with suction cups 12 in a one-to-one correspondence, and the suction cups 12 are elastic structures;

[0064] Furthermore, the limiting mechanism includes a limiting block 13 and a slide groove 14. The limiting block 13 is arranged on the top surfaces of the first cross bar 6, the second cross bar 7 and the third cross bar 8. The top surfaces of the limiting block 13 are inclined inwardly. The slide groove 14 is opened on the top of the first cross bar 6, the second cross bar 7 and the third cross bar 8. A slider 15 is fixedly connected to the bottom of the limiting block 13. The slider 15 is connected to the inner side of the slide groove 14 in a left-right sliding manner. A damping pad 16 is arranged between the slider 15 and the side wall of the slide groove 14.

[0065] In a specific application scenario, a first cross bar 6, a second cross bar 7 and a third cross bar 8 that can slide are arranged on the inner side of the mounting plate 3 with a frame structure. By utilizing the gap between the first cross bar 6 and the mounting plate 3, the rear column foot of the instrument can be clamped between the first cross bar 6 and the mounting plate 3. When the front-to-back distance of the column foot of the instrument is short, the front column foot of the instrument is clamped between the second cross bar 7 and the third cross bar 8 through the sliding of the second cross bar 7 and the third cross bar 8. The first cross bar 6, the second cross bar 7 and the third cross bar 8 slide in contact with the mounting plate 3 through the fitting plate 9 fixed at the bottom side of the end portion, which can prevent the first cross bar 6, the second cross bar 7 and the third cross bar 8 from rotating, and by fixing The tightening of the bolt 10 allows the first cross bar 6, the second cross bar 7 and the third cross bar 8 to be fixed on the inner side of the mounting plate 3, thereby fixing the column foot of the instrument to fix the instrument. At the same time, the first cross bar 6, the second cross bar 7 and the third cross bar 8 are provided with suction cups 12 at equal intervals on the contact surfaces with the column foot. The suction cups 12 are adsorbed on the column foot to avoid sliding during instrument detection. When the instrument has no column foot, the position of the limit block 13 is adjusted by the sliding structure of the slider 15 on the inner side of the slide groove 14, so that the instrument can be quickly placed between the limit blocks 13 to facilitate the placement of the instrument. The slider 15 contacts the slide groove 14 through the damping pad 16, which can increase friction and reduce sliding.

[0066] In addition, a telescopic sleeve rod 4 and a first adjusting rod 5 are provided between the fixed plate 2 and the mounting plate 3. By rotating the first adjusting rod 5, it can be telescoped inside the sleeve rod 4, and the height dimensions of the fixed plate 2 and the mounting plate 3 can be adjusted to adapt to the use of instruments with column feet of different lengths.

When performing a vibration test, the support plate 18 is rotated to a horizontal state, and the support plate 18 is tightened by utilizing the elastic action of the pneumatic spring 19, so that the inner side surface of the support plate 18 is tightly fitted with the horizontal side wall of the mounting seat 17, so that the fixed plate 2 loses support for vibration testing.
