[0037] See also Figures 1 to 6 , the present invention provides a double-headed slide board based on a horizontal support system, which is a supporting slide board for a vibration table in the field of vibration test technology during vibration, and comprises a slide board body 1;

[0038] The left end of the skateboard body 1 has a plurality of first bullhead connection holes 2 distributed at equal intervals in the longitudinal direction;

[0039] The first bullhead connection hole 2 is used to connect the connection hole on the bullhead 33 of the external vibration table 30 by bolts when the skateboard body 1 needs to be axially placed (axially driven at this time);

[0040] The rear end of the skateboard body 1 has a plurality of second bullhead connection holes 3 which are distributed at equal intervals in the transverse direction;

[0041] The second bullhead connection hole 3 is used to connect the connection hole on the bullhead 33 of the external vibration table 30 by bolts when the skateboard body 1 needs to be placed horizontally (at this time, it is driven horizontally);

[0042] A plurality of slide bearing connection holes 4 are provided on the slide body 1 for connecting to the slide bearing 32 on the top of the horizontal slide 31 of the external vibration table 30 through bolts.

[0043] It should be noted that the slide bearing is located at the top of the horizontal slide of the vibration table directly below the skateboard body 1.

[0044] It should be noted that the skateboard body 1 is connected to the bullhead 33 (i.e., the connecting head) of the external vibration table 30 to fix the skateboard and provide driving. The skateboard body 1 is completely fitted with the bullhead 33 of the external vibration table 30, so that the skateboard of the present invention can effectively transmit the driving of the vibration table and control the movement direction to a certain extent.

[0045] In the present invention, in a specific implementation, the shape of the skateboard body 1 is a combination of a rectangle and a trapezoid.

[0046] In the present invention, in a specific implementation, the first bull head connecting hole 2 and the second bull head connecting hole 3 are in the shape of a rectangle.

[0047] In the present invention, in a specific implementation, the left and right sides of the skateboard body 1 of the double-head skateboard are respectively provided with a plurality of horizontal support platform connection holes 5 for connecting the horizontal support system 20 .

[0048] In specific implementation, each horizontal support system 20 includes a distributed horizontal base 21 and a hydrostatic bearing T-shaped slider 22;

[0049] A hydrostatic bearing T-shaped slider 22 is arranged on the top of the distributed horizontal base 21;

[0050] The top of the static pressure bearing T-shaped slider 22 is connected to the horizontal support platform connection hole 5 by bolts.

[0051] Among them, the distributed horizontal base 21 is mainly used for static load support and installation of the hydrostatic bearing T-type slide 22. The hydrostatic bearing T-type slide 22 has the same function as the slide bearing 32 on the horizontal slide 31 of the external vibration table 30, providing guidance during the movement of the vibration table.

[0052] In specific implementation, when the double-headed slide is subjected to an axial loading load test (i.e., when the slide body 1 needs to be placed axially), a plurality of horizontal support systems 20 (e.g., two) are installed on the right end outer side of the horizontal slide table 31 of the external vibration table 30;

[0053] The right end of the bottom of the double-headed slide is connected to a horizontal support system 20 (specifically connected to a hydrostatic bearing T-shaped slide block 22 on the horizontal support system 20);

[0054] In specific implementation, when a double-headed skateboard is subjected to a lateral loading test (when the skateboard body 1 needs to be placed horizontally), a plurality of horizontal support systems 20 (for example, two) are respectively provided on the front and rear sides of the horizontal slide table 31 of the external vibration table 30;

[0055] The front and rear sides of the bottom of the double-headed slide are respectively connected to a plurality of horizontal support systems 20 (specifically, the hydrostatic bearing T-shaped sliders 22 on the horizontal support systems 20).

[0056] In a specific implementation, the height of the hydrostatic bearing T-shaped slider 22 is the same as the height of the slide bearing 32 of the horizontal slide 31 .

[0057] It should be noted that the external vibration table 30 is an existing vibration table, and a plurality of slide bearings 32 are installed on the horizontal slide 31, and the slide bearings 32 provide a guiding function during the movement of the vibration table. The external vibration table 30 is a vibration table with mature existing technology, and the specific structure is not repeated here. In specific implementation, the external vibration table 30 is an electric vibration table (for example, an electric vibration table of model H3580A produced by Aerospace Hill Company can be used, which can perform vibration tests, impact tests, etc.), which can generate horizontal thrust.

[0058] It should be noted that, for the present invention, the horizontal support system 20 is subjected to an axial test (see Figure 6) is mounted on the far end of the horizontal slide table 31 of the external vibration table 30 (such as Figure 5 , Figure 6 right side as shown), perform a lateral test (see Figure 3 , Figure 4 As shown in the figure, the two components are installed in groups on both sides of the horizontal slide 31 of the external vibration table 30. During installation, it is necessary to ensure that the height of the hydrostatic bearing T-shaped slider 22 in the horizontal support system 20 is adjusted to the same height as the slide bearing 32 of the horizontal slide 31.

[0059] It should be noted that the horizontal support system is installed on both sides of the horizontal slide base of the original vibration table according to the size of the product.

[0060] It should be noted that, in the present invention, the double-headed slide plate is designed with connection holes in both the axial and transverse directions, so that it can be connected to the vibration table bull head in both the transverse and axial directions.

[0061] It should be noted that, for the present invention, the double-headed slide plate has relatively large strength and rigidity in the axial and lateral directions, and has strong anti-overturning capability.

[0062] It should be noted that, for the present invention, the double-headed skateboard of the present invention is lighter than the original skateboard, and can load a higher load on the product under the same thrust, or the double-headed skateboard is longer than the original skateboard, meeting the requirements for static load placement of the product.

[0063] In order to more clearly understand the technical solution of the present invention, the working principle of the present invention is described below.

[0064] The connection between the double-head slide plate and the horizontal slide table of the vibration table is divided into two directions: axial and lateral.

[0065] When axially connecting, place the double-headed slide plate axially in the same direction of motion of the moving coil of the horizontal slide and the vibration table, align the slide plate with the original slide bearing connection hole (i.e. align the slide bearing connection hole 4 with the connection hole of the horizontal slide bearing of the vibration table) and with the vibration table bull head hole (i.e. align the first bull head connection hole 2 with the connection hole of the bull head of the external vibration table), and connect the holes respectively with bolts, and tighten the bolts to the specified torque;

[0066] When connecting horizontally, place the double-headed skateboard horizontally in the same direction of movement of the dynamic coil of the horizontal slide and the vibration table, align the skateboard with the connection hole of the original slide bearing (that is, align the slide bearing connection hole 4 with the connection hole of the bearing on the horizontal slide of the vibration table) and the connection hole of the horizontal support system, align the skateboard with the bull head hole of the vibration table (that is, align the second bull head connection hole 3 with the connection hole of the bull head of the external vibration table), and tighten the bolts to the specified torque.

[0067] It should be noted that the present invention is not limited to the above-mentioned transversely installed horizontal support system. The axial horizontal support system can also be installed according to needs. There is more than one axial and transverse horizontal support system. Any obvious improvements, replacements or changes made by technical personnel in this field on the basis of the present invention are within the scope of protection of the present invention.

[0068] To sum up, compared with the prior art, the double-headed skateboard based on the horizontal support system provided by the present invention has a scientific structural design, can load the product in the lateral and axial directions, give full play to the thrust of the vibration table, and thus better meet the index requirements of product assessment.

[0069] In view of the increasingly higher requirements for product loading loads in the market and the increasing assessment needs for slender products, the original slide table size and vibration table indicators of the vibration table can no longer meet the product size installation and assessment indicator requirements. Taking into account the economy and the maximum thrust capacity of the vibration table, the present invention improves on the original slide table system and designs a double-headed slide plate based on the horizontal support system to meet the load loading requirements of the products.

[0070] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
