DETAILED DESCRIPTION

[0022] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as the whole of the present invention or as a limitation or restriction to the technical solution of the present invention.

[0023] See also Figure 1 , Figure 2 , which shows an example of a vibration device of the present application. The hardware architecture of the vibration device 100 is mainly composed of main parts such as a box body 1, a vibration table 2, a door body 3, an electrical and pneumatic system, a heating and cooling system, etc.

[0024] The box body 1 is mainly composed of a box body steel frame, a box body liner, a box body shell and a box body polyurethane foam layer, etc. The box body 1 in this example is provided with a cavity inside.

[0025] The vibration table 2 is installed in the inner cavity of the box body 1 and divides the inner cavity of the box body 1 into an upper chamber 11 and a lower chamber 12; the upper chamber 11 is a vibration chamber, and multiple electrical or pipeline components will be installed in the lower chamber 12. The vibration table 2 includes a lower table 213, a rigid table 212, a middle spacer 211 between the lower table 213 and the rigid table 213, and multiple vibration air hammers 22 connected to the bottom side of the lower table 213 at an inclined angle. The multiple vibration air hammers 22 can generate three-axis six-degree-of-freedom random vibrations in the rigid table 212 and one or more target objects (not shown in the figure) loaded thereon.

[0026] The electrical and pneumatic system will be installed in the lower chamber 12 of the box 1 and in the electrical box between the outer shell and the inner tank of the box 1 and on the outer shell side of the box 1. The electrical part of the electrical and pneumatic system is mainly used to execute the instructions of the host computer to control the electrical proportional valve, and through the electrical proportional valve, the precision pressure reducing valve outputs the required air pressure, thereby controlling the acceleration value of the vibration table 2 in real time. The pneumatic system of the electrical and pneumatic system is connected to the intake and exhaust pipes of multiple vibrating air hammers 22. The pneumatic system consists of an intake pipeline, an air filter, a pressure reducing valve, an electrical proportional valve, a precision pressure reducing valve, an oil mist collector, an air supply pipeline, an air return pipeline, an air collection bag, an exhaust cleaner, etc.

[0027] The heating and cooling system is configured to selectively change the temperature of the upper chamber 11 or the target object loaded on the vibration table 2. In a typical example of a heating and cooling system, the heating and cooling system includes one or more electric heaters, one or more microwave heaters, and a refrigeration device. The operator controls the one or more electric heaters, one or more microwave heaters, and the refrigeration device to adjust the temperature of the upper chamber 11 or the target object to the target temperature, such as heating to 200°C or cooling to minus 100°C. Among them, one or more electric heaters can indirectly change the temperature of the target object by changing the temperature in the upper chamber 11; one or more microwave heaters can send microwaves into the upper chamber 11 to heat the target object on the vibration table 2. One or more electric heaters, one or more microwave heaters, and a refrigeration device can use conventional devices that can reach the set required temperature, which will not be repeated here.

[0028] like Figure 3 and Figure 5 As shown, the rigid table 212 includes a metal middle plate 2121, an upper inorganic material plate 2122 bonded and fixed to the upper surface of the metal middle plate 2121, a lower inorganic material plate 2123 bonded and fixed to the lower surface of the metal middle plate 2121, and a metal thin plate 2124 bonded and fixed or fixed to the upper surface of the upper inorganic material plate 2122 by a fixing member 23. The metal middle plate 2121 and the metal thin plate 2124 can be made of metal materials such as aluminum, stainless steel, etc., and the upper inorganic material plate and the lower inorganic material plate can be made of inorganic heat-resistant materials.

[0029] The metal sheet 2124 is configured as a two-dimensional bearing surface for supporting one or more target objects. The thickness of the metal sheet 2124 can be selected to be 0.3-0.6 mm. Similarly, with the help of the fixing member 23, one or more target objects can be fixed on the metal sheet 2124. The fixing member 23 can be a threaded fastening component or other components that can fix one or more target objects on the two-dimensional bearing surface.

[0030] See also Figure 2 and Figure 3 As shown, there is a gap 102 between the outer periphery of the vibration table 2 and the inner wall surface 101 of the box body 1, and a partition component 4 is arranged in the gap 102.

[0031] See also Figure 4 As shown, the partition assembly 4 includes an upper metal mesh 41, a lower metal mesh 42 and a heat insulating member 43. The heat insulating member 43 is located between the upper metal mesh 41 and the lower metal mesh 42.

[0032] The heat insulating member 43 is made of heat-resistant waterproof cloth material, such as silicone waterproof cloth made of silicone cloth material. Sometimes, water will be generated in the upper chamber 11. In order to discharge the condensed water in the upper chamber 11, one or more liquid discharge holes 431 are also provided on the heat insulating member 43.

[0033] The upper metal mesh 41 and the lower metal mesh 42 are both made of metal woven mesh, and the mesh number of the metal woven mesh can be selected to be greater than or equal to about 80 meshes, preferably 80-120 meshes.

[0034] Continue to see Figure 5, the partition assembly 4 has a side portion 401 and a side portion 402 opposite to each other. The side portion 401 is tightly pressed against the outer peripheral side wall of the rigid table 212 by the metal strip 51, and is fixed to the metal middle plate 2121 of the rigid table 212 by a plurality of metal fasteners 52 (such as metal threaded fasteners, riveted fasteners, etc.) that penetrate the metal strip 51 and the side portion 401. Since the metal fasteners 52 penetrate the metal strip 51, the double-layer metal mesh at the side portion 401, and the metal middle plate 2121 at the same time; and since all metals have conductive properties, the metal strip 51, the upper metal mesh 41, the lower metal mesh 42, and the metal middle plate 2121 are mutually electrically conductive through these metal fasteners 52.

[0035] In this example, the metal strip 51 is in a right-angle shape, and part of the metal strip 51 is located on the upper side of the metal sheet 2124 and is in close contact with the metal sheet 2124; thus, with the help of the conductive properties of the metal strip 51, the metal sheet 2124, the metal strip 51, the upper metal mesh 41, the lower metal mesh 42 and the metal intermediate plate 2121 are electrically connected to each other through a plurality of metal fasteners 52.

[0036] The inner wall surface 101 of the box body 1 has a convex rib 103. The side edge portion 402 of the partition assembly 4 is crimped onto the convex rib 103 by the metal bead 53, and is fixed to the side surface of the convex rib 103 by a plurality of metal fasteners 54 that penetrate the metal bead 53. That is, each metal fastener 54 simultaneously penetrates the metal bead 53, the double-layer metal mesh at the side edge portion 402, and the convex rib 103, and due to the conductivity of the metal, the metal bead 53, the upper metal mesh 41, the lower metal mesh 42, and the convex rib 103 are electrically connected to each other through these metal fasteners 54.

[0037] In this example, the metal strip 53 is also in a right angle shape, and a portion of the metal strip 53 is located on the upper side of the rib 103 and contacts the rib 103 .

[0038] In other embodiments, the inner wall surface of the box body may not be provided with ribs, but the corresponding side portions of the partition assembly may be directly fixed to the inner wall surface of the box body through an I-shaped metal strip and a plurality of threaded fasteners.

[0039] The partition assembly of the present application can not only effectively reduce the heat in the upper chamber 11 from diffusing to the lower chamber 12, but also the upper and lower metal meshes can effectively play a role in microwave shielding. In addition, due to the effects of the metal bead 51 and the metal bead 53, the upper metal mesh 41 and the lower metal mesh 42 can form a tight connection with the metal middle plate 2121 of the rigid table 212, the metal thin plate 2124, and the inner wall surface 101 and the convex rib 103 of the box body, so that microwaves are not easy to leak; the heat insulation 43 set between the double-sided metal meshes can effectively prevent the upper and lower metal meshes from igniting when the vibration table 2 vibrates, thereby making the use of the vibration equipment safer.

[0040] The vibration equipment of the present application can be used for performance testing of new products and new parts, and can also be used for processing product blanks; when being used for processing product blanks, bubbles in the product blanks can be effectively removed with the help of vibration.

[0041] The technical scope of the present invention is not limited to the contents in the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
