Description

Technical Field

[0001] This utility model relates to the field of magnetic levitation generator performance testing technology, specifically a magnetic levitation generator performance testing device. Background Technology

[0002] Magnetic levitation generator performance testing equipment typically includes a drive system that provides stable power and drive to the generator. This drive system is connected to the generator's input terminal via electrical wiring to ensure that the generator can operate at preset speed and load conditions. Before performance testing, the magnetic levitation generator needs to be securely mounted on the test platform to ensure that it does not move or vibrate during the test.

[0003] However, existing magnetic levitation generator performance testing equipment usually clamps the generator on both sides and drives the clamping mechanism to move the clamped generator in multiple directions through a drive mechanism to align the generator's shaft with the center of the testing machine. The process of aligning the generator's shaft with the center of the testing machine is relatively complicated and inconvenient to align the generator's shaft with the center of the testing machine in one go, making the operation inconvenient.

[0004] Furthermore, the clamping device is inconvenient for clamping and fixing the generator on multiple sides, which may cause the generator to vibrate or move during the testing process of the equipment being tested, resulting in poor stability. Therefore, it is necessary to propose a magnetic levitation generator performance testing device to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a magnetic levitation generator performance testing device, which features high installation efficiency by aligning the generator's shaft with the center of the testing machine through a central limiting mechanism, and the ability to clamp and limit multiple surfaces of the generator, thereby improving the generator's stability during testing.

[0006] The purpose of this utility model is to provide a magnetic levitation generator performance testing device, including a base frame and a testing machine. The upper end of the base frame is provided with two left and right vertically distributed centering limiting mechanisms. Each centering limiting mechanism includes a support column. The outer wall of the support column is slidably connected with a symmetrically distributed first driving rod and a second driving rod. The outer wall of the first driving rod is fixedly connected with a first limiting block. The other end of the first limiting block is slidably connected to the second driving rod. The outer wall of the second driving rod is equipped with a second limiting block. The other end of the second limiting block is slidably connected to the first driving rod.

[0007] A fixing rod is fixedly connected to the outer wall of the support column, and a connecting rod is movably connected to the outer wall of the fixing rod via a rotating shaft. Two symmetrically distributed grooves are opened through the outer wall of the connecting rod.

[0008] The outer walls of both the first and second drive rods are fixedly connected to support shafts, and the two support shafts pass through the grooves and are slidably connected to the grooves.

[0009] A mounting plate is fixedly connected to one side of the support column, and a first electric actuator is installed on the outer wall of the mounting plate. The output end of the first electric actuator passes through the mounting plate and is fixedly connected to a second drive rod.

[0010] The center point of the axial connection end of the testing machine is coaxially distributed with the center point between the first limiting block and the second limiting block.

[0011] To facilitate the movement of the clamped magnetic levitation generator, as a preferred embodiment of the magnetic levitation generator performance testing equipment of this utility model, a vertical plate is fixedly connected to the right end of the base frame, a second electric push rod is installed at the right end of the vertical plate, the output end of the second electric push rod passes through the vertical plate and is fixedly connected to a horizontal plate, the upper end of the horizontal plate is fixedly connected to the support column of the left centering limiting mechanism through a first connecting rod, and the upper end of the horizontal plate is fixedly connected to the support column of the right limiting mechanism through a second connecting rod.

[0012] To facilitate limiting the rear end of the magnetic levitation generator, as a preferred embodiment of the magnetic levitation generator performance testing equipment of this utility model, a third electric push rod is installed at the right end of the second connecting rod, and the output end of the third electric push rod passes through the second connecting rod and is fixedly connected to a third limiting plate.

[0013] To increase the stability of the horizontal plate during movement, as a preferred embodiment of the magnetic levitation generator performance testing equipment of this utility model, the lower end of the horizontal plate is slidably connected to the base frame through two front-to-back distributed sliders.

[0014] To further increase the stability of the fixed magnetic levitation generator, as a preferred embodiment of the magnetic levitation generator performance testing equipment of this utility model, the second limiting block and the side opposite to the first limiting block are both provided with V-shaped grooves.

[0015] For ease of operation, a controller is preferably installed at the front end of the testing machine, which is a preferred embodiment of the magnetic levitation generator performance testing equipment of this utility model.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] In this invention, a first electric actuator drives two second drive rods to move. During the movement of the second drive rods, the connecting rod is pulled to rotate. At this time, the support shaft slides inside the groove. When the connecting rod rotates, it drives the support shaft connected to it to move. At the same time, the support shaft drives the first drive rod, the first limiting block, the second drive rod, and the second limiting block connected to it to move. This allows the outer wall of the magnetic levitation generator to be clamped and fixed. The centering limiting mechanism at the left end can clamp the front and rear sides of the magnetic levitation generator, and the centering limiting mechanism at the right end can clamp the upper and lower sides of the magnetic levitation generator. At the same time, the magnetic levitation generator is centered so that the axis of the magnetic levitation generator is coaxial with the connection end of the testing machine.

[0018] In summary, the generator shaft can be aligned with the center of the testing machine through the centering limiting mechanism, resulting in high installation efficiency. Furthermore, multiple surfaces of the generator can be clamped and limited, improving the stability of the generator during testing. Attached Figure Description

[0027] The center point of the shaft connection end of the test machine 2 is coaxially distributed with the center point of the first limiting block 15 and the second limiting block 16.

[0028] In this embodiment: During use, the magnetic levitation generator to be tested is first placed between the first limiting block 15 and the second limiting block 16, and the first electric push rod 12 is activated to drive the second drive rod 14 to move. During the movement of the second drive rod 14, the connecting rod 18 is pulled to rotate. At this time, the support shaft 17 slides inside the groove 20. When the connecting rod 18 rotates, it drives the support shaft 17 connected to it to move. At the same time, the support shaft 17 drives the first drive rod 13, the first limiting block 15, the second drive rod 14, and the second limiting block 16 connected to it to move, thereby clamping and fixing the outer wall of the magnetic levitation generator. The front and rear sides of the magnetic levitation generator can be clamped by the centering limiting mechanism at the left end, and the upper and lower sides of the magnetic levitation generator can be clamped by the centering limiting mechanism at the right end. At the same time, the magnetic levitation generator is centered, so that the axis of the magnetic levitation generator is coaxial with the connection end of the testing machine 2. The operation is simple and the stability of the magnetic levitation generator is increased.

[0029] As a technical optimization of this utility model, a vertical plate 3 is fixedly connected to the right end of the base frame 1, a second electric push rod 4 is installed on the right end of the vertical plate 3, the output end of the second electric push rod 4 passes through the vertical plate 3 and is fixedly connected to a horizontal plate 5, the upper end of the horizontal plate 5 is fixedly connected to the support column 10 of the left centering limiting mechanism through the first connecting rod 9, and the upper end of the horizontal plate 5 is fixedly connected to the support column 10 of the right limiting mechanism through the second connecting rod 6.

[0030] In this embodiment: the horizontal plate 5 can be moved by the second electric push rod 4. When the horizontal plate 5 moves, the two centering limit mechanisms are moved by the first connecting rod 9 and the second connecting rod 6. This process can drive the clamped magnetic levitation generator to move.

[0031] As a technical optimization of this utility model, a third electric push rod 7 is installed at the right end of the second connecting rod 6, and the output end of the third electric push rod 7 passes through the second connecting rod 6 and is fixedly connected to a third limiting plate 8.

[0032] In this embodiment: the third electric push rod 7 can drive the third limiting plate 8 to move, and the third limiting plate 8 can abut against the rear end of the magnetic levitation generator, thereby limiting the rear end of the magnetic levitation generator.

[0033] As a technical optimization of this utility model, the lower end of the horizontal plate 5 is slidably connected to the base frame 1 through two front-to-back sliding blocks.

[0034] In this embodiment, the lower end of the horizontal plate 5 is slidably connected to the base frame 1 through two front-to-back sliding blocks, which can increase the stability of the horizontal plate 5 when it moves.

[0035] As a technical optimization of this utility model, the second limiting block 16 and the first limiting block 15 are both provided with V-shaped grooves on their opposite sides.

[0036] In this embodiment, the magnetic levitation generator is clamped between multiple V-grooves, which further increases the stability of the fixed magnetic levitation generator.

[0037] As a technical optimization of this utility model, a controller is installed at the front end of the test machine 2.

[0038] In this embodiment, the controller is electrically connected to the first electric actuator 12, the second electric actuator 4, and the third electric actuator 7, making operation more convenient.

[0039] Working principle: When in use, first place the magnetic levitation generator to be tested between the first limiting block 15 and the second limiting block 16, and start the first electric push rod 12 to drive the second drive rod 14 to move. During the movement of the second drive rod 14, the connecting rod 18 is pulled to rotate. At this time, the support shaft 17 slides inside the groove 20. When the connecting rod 18 rotates, it drives the support shaft 17 connected to it to move. At the same time, the support shaft 17 drives the first drive rod 13, the first limiting block 15, the second drive rod 14, and the second limiting block 16 connected to it to move, so as to clamp and fix the outer wall of the magnetic levitation generator. The front and rear sides of the magnetic levitation generator can be clamped by the centering limiting mechanism at the left end, and the upper and lower sides of the magnetic levitation generator can be clamped by the centering limiting mechanism at the right end.

[0040] Next, the third limit plate 8 is moved by the third electric push rod 7, and the third limit plate 8 is brought into contact with the rear end of the magnetic levitation generator, which can limit the rear end of the magnetic levitation generator.

[0041] Then, the horizontal plate 5 can be moved by the second electric push rod 4. When the horizontal plate 5 moves, it drives the two centering limit mechanisms to move through the first connecting rod 9 and the second connecting rod 6. This process can drive the clamped magnetic levitation generator to move.
