Description

A combined vibration device Technical Field

[0001] This invention belongs to the field of experimental device structural design technology, and specifically refers to a combined vibration testing device with a split servo mechanism. Background Technology

[0002] Traditional servo mechanisms typically integrate all functional physical structures into a single component, requiring only the design of corresponding fixtures for delivery and vibration devices. Split-type servo mechanisms, lacking individual compartments, are ultimately produced and tested as several independent components. This necessitates multiple integrations and assemblies into a projectile state throughout the production process, resulting in repeated installations and disassemblies that impact delivery schedules. Furthermore, these repeated installations and disassemblies may damage the product, posing safety hazards and failing to meet the demands of rapid production and delivery.

[0003] The currently used integrated vibration device can integrate the split servo mechanism into a compartment by simulating the structure of a projectile, reducing the number of disassembly and assembly times during the production process. However, the integrated vibration device has a long processing cycle, high production cost, and large size and weight, making it difficult to meet the requirements of flexible assembly and rapid production and delivery of split servo mechanisms. Therefore, it is particularly important to design a test device for split servo mechanisms. Summary of the Invention

[0004] The purpose of this invention is to provide a split-type combined vibration device to meet the production and delivery requirements of split-type servo mechanisms. The vibration device is designed in a combined form, and is assembled using basic structural components that are simple in structure and easy to process. This solves the problems of high production cost, long processing cycle, heavy weight, and difficulty in flexibly combining and configuring the original integrated vibration device for various working conditions.

[0005] The technical solution of the present invention is as follows: To achieve the above-mentioned tasks, the present invention adopts the following technical solution: a combined vibration device, comprising a support I, a support II, a support III, a support frame, a reinforcing column, a reinforcing plate, and a supporting cylinder; wherein, the reinforcing column connects the support II and the support III, and an independent transmission mechanism can be installed between the outer surfaces of the support II and the support III; the reinforcing plate is installed on the outer surfaces of the support I and the support II, connecting the two, and a control component can be installed on the reinforcing plate; the support frame is disposed between the support I and the support II, and is mounted on the reinforcing plate from the side, and the transmission mechanism and the control component can be integrated together for vibration testing through the support frame, the reinforcing column, and the reinforcing plate, or the two components can be tested separately; two supporting cylinders are respectively installed on the lower surface of the support I and the upper surface of the support III, and the supporting cylinders at both ends are used to adapt to different clamp interface requirements.

[0006] As a further solution of the present invention: The supporting cylinders at both ends of the combined vibration device are of annular structure, with 12 M10 threaded holes evenly distributed on the end faces and 4 M5 threaded holes evenly distributed on the outer cylindrical surfaces.

[0007] As a further solution of the present invention: The support I, support II, and support III are of regular hexagonal prism structure, with a circular through-hole in the middle, and threaded holes and counterbored holes are machined on the upper and lower end faces; there are M5 threaded holes on the side surfaces.

[0008] As a further solution of the present invention: The strengthening column is of cylindrical structure, with an external thread provided at one end and a threaded hole provided at the other end, and there is a bolt on the support II or support III that is adapted to the threaded hole, and the length of the cylindrical section limits the installation positions of the support I, support II, and support III.

[0009] As a further solution of the present invention: The strengthening plate is of a "day" - shaped frame structure, with M10 threaded holes provided on the short end faces of the frame, M4 screw holes provided on the long end faces of the frame, and counterbored holes provided on the strengthening ribs in the middle of the frame.

[0010] As a further solution of the present invention: A support frame is installed at the middle position between the support II and the support III, and the support frame is connected to the strengthening rib on the strengthening plate by screws.

[0011] As a further solution of the present invention: It further includes a base I, which is connected to the supporting cylinder on the side of the support I, and is designed as a square plate plus a convex platform structure, including a perforated square plate and four convex platforms that are circumferentially distributed and perpendicularly connected to the perforated square plate. There are counterbored holes on the side surfaces of the convex platforms, and the convex platforms are designed as arc - shaped stepped plates.

[0012] As a further solution of the present invention: It further includes a base II, which is connected to the supporting cylinder on the side of the support III, and is of a circular end face plus a convex platform structure, including a perforated circular plate and four convex platforms that are circumferentially distributed and perpendicularly connected to the perforated circular plate.

There is a cylindrical through - hole on the end face of the perforated circular plate, and counterbored holes on the side surfaces of the convex platforms. The convex platforms are designed as arc - shaped stepped plates, and the convex platforms around are used for installation and fixation with the supporting cylinder.

[0013] The beneficial effects of the present invention are as follows: 1. By adopting the variable stiffness structure design technology of support + support frame + strengthening column + strengthening plate + supporting cylinder, a good match among the structural weight, structural stiffness, and modal characteristics is achieved.
