[0002] In the structure of an electric vibration table, the dynamic coil is a key component that determines the performance indicators of the equipment, and the suspension device of the dynamic coil determines the system indicators of the vibration table.

[0003] Because it is limited by the effective working range of the guide device, the travel of the dynamic coil inside the table is limited. There will be a mechanical limit structure inside the table to prevent the dynamic coil from leaving the normal use range. This limit structure is fixed relative to the table. If the dynamic coil moves beyond the normal travel, it will collide with the limit structure, causing damage to the dynamic coil. In addition, a flexible connection method can be used to limit the dynamic coil, but the existing flexible connection structure is difficult to fix with the dynamic coil and the vibration table.

[0004] In view of this, it is necessary to improve the existing damping unit to solve the above problems. Utility Model Content

[0008] As a further improvement of the present invention, the thickness of the mounting plate along the axial direction is smaller than the thickness of the connecting plate, and the mounting plate is arranged in the middle of the connecting plate along the axial direction.

[0009] As a further improvement of the present invention, the attachment holes are divided into two rows, and the number of attachment holes in each row is at least two.

[0010] As a further improvement of the present invention, at least one connecting hole is provided on the connecting plate.

[0011] As a further improvement of the utility model, the cross-section of the connecting plate along the axial direction is hexagonal, the number of the connecting holes is two, and the two connecting holes are arranged on both sides of the injection molding groove.

[0012] As a further improvement of the utility model, the injection molding groove is rectangular, and the length of the injection molding groove along the height direction is greater than the width along the horizontal direction.

[0013] As a further improvement of the present invention, the elastic damping element is formed by injection molding or sealing.

[0014] The utility model also provides a large displacement vibration table, which includes a vibration table body, a plurality of columns arranged on the vibration table body, a moving coil arranged on the vibration table body, and a damping unit as described above connected between the moving coil and each of the columns, wherein the inserts of the damping unit are fixedly connected to the columns and the moving coil respectively.

[0015] As a further improvement of the present invention, the number of the damping units connected between the moving coil and each of the columns is greater than or equal to two, and adjacent inserts of two adjacent damping units are fixedly connected.

[0024] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0026] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] like Figures 1 to 6 As shown, the large displacement vibration table 100 of the utility model includes a vibration table body 1, a plurality of columns 2 arranged on the vibration table body 1, a dynamic coil 3 arranged on the vibration table body 1, and a damping unit 4 connected between the dynamic coil 3 and each of the columns 2.

[0028] The damping unit 4 includes inserts 41 arranged at two ends and elastic damping members 42 connected between the inserts 41 at the two ends.

[0029] The insert 41 is made of metal or non-metal material with high tensile strength to bear the tensile force of the elastic damping member 42 .

[0030] The insert 41 includes a connecting plate 411, an injection molding groove 412 opened in the middle of the connecting plate 411, and a mounting plate 413 disposed in the injection molding groove 412. The insert 41 of the damping unit 4 is fixedly connected to the column 2 and the moving coil 3 respectively.

[0031] Two ends of the elastic damping member 42 are formed in the injection molding grooves 412 of the insert 41 at both sides. The elastic damping member 42 is formed by injection molding or sealing.

[0032] The cross section of the connecting plate 411 along the axial direction is hexagonal, the injection groove 412 is rectangular, and the injection groove 412 is arranged in the middle of the connecting plate 411 .

[0033] At least one connection hole 414 is formed on the connection plate 411. In this embodiment, there are two connection holes 414, and the two connection holes 414 are arranged on both sides of the injection groove 412. The connection hole 414 is a threaded hole for the screw 43 to pass through. The connection hole 414 is used to fix two adjacent damping units 4 to each other, and to be fixedly connected to the column 2 and the moving coil 3. In this embodiment, the connection plate 411 has a good connection effect, thereby realizing the connection between the damping units 4 and the connection with other structures.

[0034] The length of the injection molding groove 412 in the height direction is greater than the width in the horizontal direction. This configuration makes the thickness of the elastic damping member 42 in the height direction greater than the width in the horizontal direction, thus having a better damping effect in the height direction.

[0035] At least two attachment holes 415 are formed in the axial direction on the mounting plate 413. The attachment holes 415 can improve the adhesion of the elastic damping member 42. In this embodiment, the attachment holes 415 are divided into two rows, and the number of attachment holes 415 in each row is at least two.

[0036] The thickness of the mounting plate 413 along the axial direction is smaller than that of the connecting plate 411, and the mounting plate 413 is arranged in the middle of the connecting plate 411 along the axial direction. In this way, the elastic damping member 42 can completely cover the mounting plate 413, and the elastic damping member 42 has better tensile strength. The mounting plate 413 improves the installation effect of the elastic damping member 42.

[0037] The number of the damping units 4 connected between the moving coil 3 and each of the columns 2 is greater than or equal to two, and the adjacent inserts 41 of two adjacent damping units 4 are fixedly connected. When greater than or equal to two damping units 4 are used in series, the displacement offset can be increased. In this embodiment, the number of the columns 2 is four, and the four columns 2 are arranged around the vibration table body 1, and the number of the damping units 4 between each column 2 and the moving coil 3 is two.

[0038] The large displacement vibration table 100 connects the moving coil 3 and the column 2 by setting a damping unit 4, so that the up and down movement of the moving coil 3 is limited by the damping unit 4, eliminating the hard limiting structure, and realizing the limiting function by the damping unit 4. And the greater the displacement of the moving coil 3, the greater the deformation of the damping unit 4, and the stronger the restoring force generated, that is, the damping limiting function is played.

[0039] The large displacement vibration table 100 and the damping unit 4 of the utility model are connected to the elastic damping member 42 by providing inserts 41 on both sides. The inserts 41 realize the connection between the damping units 4 and other structures of the large displacement vibration table 100, so that the damping unit 4 has a better fixing effect, and the mounting plate 413 enables the elastic damping member 42 to have a better installation effect. More than two damping units 4 can be used in series, which can increase the displacement deflection and improve the general performance of the damping unit 4.

[0040] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
