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, features limited to "first", "second", etc. may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0026] In the specific implementation process, refer to Figures 1-4 As shown, traditional vibration table top replacement devices usually require drilling holes in the table top for fixing with vertical bolts. This not only increases the complexity of table top processing, but also may weaken the overall strength of the table top, causing stress concentration during vibration and increasing the risk of table top damage. To solve this problem, the following method is adopted:

[0027] 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;

[0028] 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 with the table panel fixing bolts 9 and table panel fixing nuts 8. The middle plate 1 provides a flat and solid platform that can evenly distribute the vibration load and ensure that the table panel remains stable during the vibration process without deformation or displacement.

[0029] The upper side panels 2 and the lower side panels 3 are fixed above and below the middle panel 1 respectively, providing upper and lower supports for the table top. The side panels are firmly connected to the middle panel 1 by bolts to form a stable frame structure. Holes are opened on the adjacent sides of the upper and lower side panels at the same intervals. The table panel fixing nuts 8 and the vibration table fixing nuts 6 are tightly connected to the openings. Together with the table panel fixing bolts 9 and the vibration table fixing bolts 7, the side panels can be clamped. The clamping effect of the side panels further enhances the fixing effect of the table panel, ensuring that the displacement of the table top during operation is consistent with the displacement of the fixing device, avoiding loosening or instability that may occur during vibration.

[0030] Specifically, the bottom of the upper side panel 2 is stepped, and the upper side panel 2 is provided with a plurality of movable grooves 10 at equal intervals on two adjacent sides. The lower side panel 3 is slidably mounted on the inner wall of the upper side panel 2. The lower side panel 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. The vibration table fixing nut 6 is threadedly fitted with a vibration table fixing bolt 7. The lower side panel 3 and the upper side panel 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 panel 2 and is fastened to the vibration table.

[0031] Furthermore, the upper side plate 2 and the lower side plate 3 are slidable, 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 accommodate table panels of different specifications and thicknesses;

[0032] It should be noted that the upper side plate 2 is provided with a plurality of openings 2 at equal intervals on adjacent sides, and the openings 2 are fitted with table panel fixing nuts 8, which are threadedly fitted with table panel fixing bolts 9, and one end of the vibration table fixing bolt 7 is fastened to the table panel;

[0033] The device's rational structural design and strong stability reduce the frequency and difficulty of routine maintenance. This prevents wear on the vibration table's original bolt holes, extending its service life. Users no longer need to frequently replace the device or perform complex repairs, reducing equipment maintenance costs and improving economic benefits.

[0034] Example 2

[0035] In a specific implementation process, refer to Figure 1 as well as Figure 4 As shown, a plurality of stiffening ribs 11 are provided on the outer surface of the upper side plate 2 at equal circumferential distances, which are mainly used to improve the overall rigidity and vibration resistance of the device. When the vibration table is working, the stiffening ribs 11 can effectively resist the vibration stress from the table surface and prevent structural deformation, thereby ensuring that the table surface 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.

[0036] Example 3

[0037] In a specific implementation process, refer to Figure 1 As shown, a plurality of through holes 12 are arranged in an array on one side of the middle plate 1, which can evenly disperse the vibration load and ensure that the table top remains stable during the vibration process without deformation or displacement.

[0038] The working principle provided by the utility model is as follows: when the device is in use, the vibration table fixing nut 6 is threadedly fitted with the vibration table fixing bolt 7, the lower side panel 3 and the upper side panel 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 panel 2 and is fastened to the vibration table, the upper side panel 2 is provided with a plurality of openings 2 at equal intervals on two adjacent sides, and the table panel fixing nut 8 is embedded in the opening 2, the table panel fixing nut 8 is threadedly fitted with the table panel fixing bolt 9, one end of the vibration table fixing bolt 7 is fastened to the table panel, and the upper side panel 2 and the lower side panel 3 can slide between each other, 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 panel 2 can be adjusted to adapt to table panels of different specifications and thicknesses.
