Embodiment 1

[0033] continue to refer Figure 1 ~ Figure 2 , the lightweight moving coil skeleton structure of the electric vibrating table is integrally formed by casting technology first, and then finished by turning and milling. Specifically, its main structure includes a table top 1, a central column 2, a rib plate 3, a skirt The plate 4, the protrusion 41 located on the upper edge of the skirt plate 4, and the reinforcement block 5 located at the joint between the rib plate 3 and the skirt plate 4 are all integrally formed by the casting process, and the rib plate 3 is reserved during the casting process. Lightening hole 31 position, then through turning and milling finish machining, lightening hole 31 is processed into circle, and projection 41 is processed into isosceles trapezoid, and reinforcing block 5 side is processed into arc-shaped notch 51, and also protruding Turn and mill the circular arc transition at the connection between the waist of the riser 41 and the upper edge of ...

Embodiment 2

[0035] continue to refer Figure 3 ~ Figure 4 , the lightweight moving coil skeleton structure of the electric vibrating table is formed by casting and machining, including a table top 1, a central column 2, ribs 3, and skirt boards 4. There are 8 ribs connected between the table top 1 and the skirt Between the plates 4 and centered on the central column 2, a square weight-reducing hole 31 is provided at the position of the rib plate 3 close to the central column 2, and an isosceles trapezoid corresponding to the position of the rib plate 3 is provided on the upper edge of the skirt plate 4 The protrusion 41 is provided with a reinforcing block 5 at the joint between the rib plate 3 and the skirt plate 4 , and the reinforcing block 5 is arranged symmetrically on the left and right sides of the protrusion 41 .

[0036] To sum up, the present invention reduces the mass of the moving coil by opening a hole near the central column of the moving coil rib, and at the same time provi...

Abstract

The invention discloses a lightweight moving coil framework structure of an electric vibration table. The structure comprises a table board, a central post, a plurality of rib plates and an apron board. The plurality of the rib plates are connected between the table board and the apron board and are uniformly distributed by taking the central post as a center, lightening holes are arranged at positions, close to the central post, on the rib plates, a plurality of reinforcing blocks are arranged on an inner side of the apron board, and the reinforcing blocks are positioned at connecting positions of the rib plates and the apron board. In the invention, the lightening holes are arranged at the positions, close to the center post, of the rib plates, the reinforcing blocks are arranged at theconnecting positions of the rib plates and the apron board, mass of a moving coil framework can be further reduced, meanwhile, rigidity of the moving coil framework is ensured, a mass-rigidity ratio of the moving coil framework is optimal, and therefore a vibration frequency of a moving coil can be further improved.

Description

technical field [0001] The invention relates to the field of moving coils of electric vibrating tables, in particular to a lightweight moving coil skeleton structure of electric vibrating tables. Background technique [0002] The electric vibration table can simulate various vibration dynamic environments, and is widely used in simulation tests of various typical vibrations such as auto parts, electronic components, and stress screening of aerospace products. The electric vibrating table is mainly composed of a moving coil assembly, a magnetic circuit assembly, a support assembly, a lower guide assembly, an upper guide assembly, an upper cover assembly, a lower cover assembly, and a support. [0003] The moving coil is the core component of the vibrating table, and its main technical requirements are: high rigidity, light weight, maximum mass-to-stiffness ratio, high resonance frequency, and low distortion. Among them, the moving coil skeleton in the moving coil is the key ...
