Description

Technical Field

[0001] This invention belongs to the field of artificial intelligence technology, specifically relating to an adjustable loading device for servo system load inertia eccentricity. Background Technology

[0002] As national requirements for the performance of military equipment become increasingly stringent, such as artillery turrets and large-aperture telescopes, servo systems need to respond quickly and with high precision under varying and unbalanced high-inertia loads. During the mechanical transmission process of the servo system, the varying and unbalanced load inertia significantly impacts accuracy. Therefore, studying the influence of varying and unbalanced load inertia on the mechanical transmission process in servo control systems has become crucial. Simulating system operation under different load inertia conditions has become a primary challenge in servo system research. The main problem currently is that it is difficult to fully reproduce the varying and unbalanced load inertia during actual motor operation during manufacturing and testing. This restricts the testing and implementation of intelligent self-diagnostic algorithms. Therefore, it is necessary to design an inertia disk that simulates unbalanced and adjustable inertia to simulate the impact of load inertia on the servo system during actual motor operation. To this end, the applicant has made a beneficial design, and the technical solution described below arose from this background. Summary of the Invention

[0003] The purpose of this invention is to provide a servo system load inertia eccentric adjustable loading device, which can simulate changing and unbalanced load inertia by adjusting the eccentric adjustable inertia disk base or changing the size and number of inertia plates.

[0004] The objective of this invention is achieved as follows: a servo system load inertia eccentric adjustable loading device includes a table base, on which a pair of spindle support frames are symmetrically arranged. A spindle is rotatably supported on the pair of spindle support frames via fixed bearings at both ends. The device also includes a load inertia eccentric adjustable loading mechanism, which comprises a fixed frame, an inertia disk base, multiple large inertia disks, and multiple small inertia disks. The fixed frame is fixedly sleeved on the spindle, and a pair of guide rods are respectively arranged at both ends along its length. The inertia... The inertia disk base is sleeved on the main shaft and located on one side of the fixed frame. On the side of the inertia disk base facing the fixed frame, a pair of connecting plates are spaced apart at both ends of the fixed frame along its length. A pair of guide rods pass through the connecting plates and are in sliding engagement with them. An adjusting nut is provided on the connecting plate at the middle position of the pair of guide rods. The adjusting nut extends towards the end of the fixed frame and cooperates with the fixed frame to change the fixed position of the inertia disk base. The multiple large inertia disks and multiple small inertia disks are sequentially stacked and connected and fixed on the side of the inertia disk base facing away from the fixed frame.

[0005] In a specific embodiment of the present invention, the large inertia disk is composed of multiple fan-shaped large inertia plates connected end to end, and the small inertia disk is composed of multiple fan-shaped small inertia plates connected end to end. The multiple large inertia disks are stacked sequentially on the inertia disk base, and the multiple small inertia disks are stacked sequentially on the large inertia disk farthest from the inertia disk base, with each small inertia plate corresponding to a large inertia plate. Several butterfly screws pass through the inertia disk base, the large inertia disk, and the small inertia disk in sequence and are fastened by butterfly nuts.

[0006] In another specific embodiment of the present invention, there are four large inertia disks and four small inertia disks.

[0007] In another specific embodiment of the present invention, the inertia disk base is composed of a pair of semi-circular disks joined together. The pair of semi-circular disks are folded outward on the joined side to form a folded edge. The folded edges are joined face to face and fastened by fastening screws. A fixing bracket clearance is formed in the middle of the folded edge.

[0008] In another specific embodiment of the present invention, a bushing is protruding on the main shaft, and the fixing bracket is attached to the bushing and fastened by fasteners.

[0009] The present invention, by employing the aforementioned structure, offers the following advantages compared to existing technologies: it can simulate varying and unbalanced load inertia through an eccentrically adjustable inertia disk base or by altering the size and number of inertia plates. This allows for the simulation of the impact of actual varying and unbalanced load inertia on the mechanical transmission process of the servo system. It enables the reproduction of variations and imbalances in load inertia encountered during actual operation under laboratory conditions, thereby testing the anti-interference capability and performance indicators of the servo system. This transforms traditional full-scale physical experiments into predictive research under laboratory conditions, thereby shortening the development cycle, saving development costs, and improving reliability and success rate.

[0015] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the description of the embodiments is not a limitation on the technical solution. Any formal but not substantive changes made based on the concept of the present invention should be considered within the scope of protection of the present invention.

[0016] In the following description, all directional (or orientational) concepts involving up, down, left, right, front, and back refer to the position of the figure being described, and are intended to facilitate public understanding. Therefore, they should not be construed as a special limitation on the technical solution provided by this invention.

[0017] Please see Figure 1 and Figure 2 This invention relates to an adjustable eccentric loading device for a servo system, comprising a table base 1, on which a pair of spindle support frames 2 are symmetrically arranged. The spindle support frames 2 are fixed to the table base 1 by nuts, and bearing seats 21 are provided on the spindle support frames 2, which are fixed by fixing bolts. A spindle 3 is rotatably supported on the pair of spindle support frames 2 through the cooperation of fixed bearings 31 at both ends with the bearing seats 21.

[0018] The key technical point of this invention is that it further includes a load inertia eccentric adjustable loading mechanism 4, which includes a fixed frame 41, an inertia disk base 42, multiple large inertia disks 43, and multiple small inertia disks 44. A bushing 32 protrudes from the main shaft 3, and the fixed frame 41 is sleeved on the main shaft 3 and fits against the bushing 32, secured by fasteners, thereby achieving a fixed connection between the fixed frame 41 and the main shaft 3. A pair of guide rods 411 are respectively provided at both ends of the fixed frame 41 along its length. The inertia disk base 42 is sleeved on the main shaft 3 and located on one side of the fixed frame 41. Specifically, the inertia disk base 42 is composed of a pair of semicircular disks 421 joined together. The semicircular disks 421 are folded outwards on their joined sides to form folded edges 4212. These folded edges 4212 are joined face-to-face and secured with fastening screws 422. A mounting bracket clearance 4213 is formed in the middle of the folded edges 4212. A pair of connecting plates 4211 are spaced apart at both ends of the mounting bracket 41 along its length on the side of the inertia disk base 42 facing the mounting bracket 41. A pair of guide rods 411 pass through the connecting plates 4211 and slide in contact with them. An adjusting nut 5 is provided on the connecting plate 4211 at the position between the pair of guide rods 411. Multiple large inertia disks 43 and multiple small inertia disks 44 are sequentially stacked and fixed to the side of the inertia disk base 42 facing away from the mounting bracket 41. When simulating unbalanced load inertia, the fixed position of the inertia disk base 42 can be changed by adjusting nut 5, causing the overall inertia disk base 42 to exhibit uneven distribution, i.e., eccentricity. By quantitatively screwing in or out adjusting nut 5, the requirements for accurately and quantitatively simulating various eccentric and unbalanced load inertia conditions under different working conditions can be met. For example, when the adjusting nut 5 is screwed toward the end of the fixed frame 41 and a force is applied to the fixed frame 41, the inertia disk base 42 moves upward. The degree of eccentricity can be quantitatively controlled by adjusting nut 5.

[0019] See you later Figure 2 and combined Figure 3 and Figure 4Furthermore, the large inertia disk 43 is composed of multiple fan-shaped large inertia plates 431 connected end to end, and the small inertia disk 44 is composed of multiple fan-shaped small inertia plates 441 connected end to end. The multiple large inertia disks 43 are stacked sequentially on the inertia disk base 42, and the multiple small inertia disks 44 are stacked sequentially on the large inertia disk 43 furthest from the inertia disk base 42, with each small inertia plate 441 corresponding to a large inertia plate 431. In this embodiment, the outer circumferential arc edges of the large inertia plates 431 and the small inertia plates 441 overlap. Several butterfly screws 45 sequentially penetrate the inertia disk base 42, the large inertia plates 431, and the small inertia plates 441, and are fastened with butterfly nuts 451. When simulating different load inertia under different working conditions, the number of large inertia plates 431 and small inertia plates 441 can be increased or decreased by disassembling the butterfly screw 45) and butterfly nut 451, thereby achieving a quantitative simulation setting of load inertia. This makes it easier to obtain the required load inertia in the laboratory for different working conditions.

[0020] This invention is primarily used to simulate load inertia under different operating conditions in servo systems. It can simulate various unbalanced, changing, and eccentric load inertia conditions. When the spindle 3 rotates, the changing and unbalanced load inertia directly acts on the working system, simulating unbalanced and changing load inertia. The load inertia can be controllably adjusted by the large inertia disk 43 and the small inertia disk 44, allowing for the application of a fixed amount of load inertia. Simultaneously, the fixed frame 41 adopts an adjustable structure design, using the adjusting nut 5 to simulate eccentric and unbalanced load inertia, applying a fixed amount of power to the spindle 3 to make it rotate. This simulates the impact of actual changing and unbalanced load inertia on the mechanical transmission process of the servo system, enabling the reproduction of load inertia changes and imbalances encountered in actual operation under laboratory conditions. This allows for the testing of the servo system's anti-interference capability and performance indicators, transforming traditional full-scale physical experiments into predictive research under laboratory conditions. This aims to shorten the development cycle, save development costs, and improve reliability and success rate.
