[0003] In the existing vibration table, the connection between the object to be measured and the vibration table surface is connected by bolts reserved on the vibration table surface. In order to achieve a firm connection, holes need to be punched on the panel, which takes a long time to connect. Frequent replacement of bolts causes great wear and tear on the bolt holes on the vibration table surface, and the replacement process is time-consuming and labor-intensive. In the use of existing vibration tables, the process of replacing the table surface is usually complicated and time-consuming, and often requires a lot of manpower and time. This cumbersome replacement process not only affects the efficiency of the use of the vibration table, but may also bring certain safety hazards, such as loose fixation, loose panels and other problems. The traditional steps for replacing the vibration table surface are cumbersome, time-consuming, labor-intensive, and difficult to operate, and require professional personnel to operate, which increases the difficulty and cost of operation.

In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0027] In the specific implementation process, refer to Figure 1-Figure 4 As shown, the traditional vibration table replacement device usually needs to drill holes on the table top so as to fix it with vertical bolts, which not only increases the complexity of table top processing, but also may weaken the overall strength of the table top, resulting in stress concentration during vibration and increasing the risk of table top damage. In order to solve this problem, the following method is adopted:

[0028] The auxiliary fixing device of the vibration table for facilitating the replacement of the table top comprises a middle plate 1, an upper side plate 2 and a lower side plate 3;

[0029] The middle plate 1 is located in the center of the device and is the main load-bearing structure of the entire device. The middle plate 1 is fixedly installed on the top of the lower side plate 3. The table panel is installed on the middle plate 1 and fastened by the table panel fixing bolts 9 and the table panel fixing nuts 8. The middle plate 1 provides a flat and solid platform that can evenly disperse the vibration load and ensure that the table panel remains stable during the vibration process without deformation or displacement.

[0030] The upper side plate 2 and the lower side plate 3 are fixed above and below the middle plate 1, respectively, to provide upper and lower supports for the table top. The side plates are firmly connected to the middle plate 1 by bolts to form a stable frame structure. Holes are opened at the same intervals on the adjacent sides of the upper and lower side plates. The table plate fixing nuts 8 and the vibration table fixing nuts 6 are tightly connected to the openings. The table plate fixing bolts 9 and the vibration table fixing bolts 7 can be used to clamp the side plates. The clamping effect of the side plates further enhances the fixing effect of the table plate, ensuring that the displacement of the table top during operation is consistent with the displacement of the fixing device, avoiding looseness or instability that may occur during vibration.

[0031] Specifically, the bottom of the upper side plate 2 is stepped, and the upper side plate 2 is provided with a plurality of movable grooves 10 at equal intervals on two adjacent sides, the lower side plate 3 is slidably mounted on the inner wall of the upper side plate 2, and the lower side plate 3 is provided with a plurality of openings 1 at equal intervals on two adjacent sides, and a vibration table fixing nut 6 is provided in the opening 1, and the vibration table fixing nut 6 is threadedly matched with a vibration table fixing bolt 7, the lower side plate 3 and the upper side plate 2 are fastened by the vibration table fixing nut 6 and the vibration table fixing bolt 7, and one end of the vibration table fixing bolt 7 passes through the movable groove 10 on one side of the upper side plate 2 and is fastened to the vibration table;

[0032] Furthermore, the upper side plate 2 and the lower side plate 3 can slide, and the position of one end of the vibration table fixing bolt 7 in the movable groove 10 on one side of the upper side plate 2 can be adjusted to adapt to table panels of different specifications and thicknesses;

[0034] Due to the reasonable structural design and strong stability of this device, the frequency and difficulty of daily maintenance are reduced. The wear of the original bolt holes of the vibration table is avoided, the service life of the vibration table is extended, and users do not need to frequently replace the device or perform complicated repairs, which reduces the maintenance cost of the equipment and improves economic benefits.

When the vibration table is working, the stiffening ribs 11 can effectively resist the vibration stress from the table top and prevent structural deformation, thereby ensuring that the table top remains stable under high-frequency vibration. The presence of the stiffening ribs 11 makes the entire device more durable and extends the service life of the device.
