Description

Technical Field

[0001] This utility model relates to the field of motor testing technology, and in particular to a multi-dimensional motor testing device based on multi-physics field coupling sensing. Background Technology

[0002] Electric motors (electric motors / generators) are core devices that convert electrical energy into mechanical energy and are widely used in industry, transportation, home appliances, and new energy fields. They achieve energy conversion through the principle of electromagnetic induction and are the "heart" of the modern industrial system. However, when testing motors of different sizes, it is inconvenient to adjust the position and height of the testing instrument, making it difficult for the instrument to get close to motors of different sizes and thus hindering the testing of motors of different sizes.

[0003] To address the aforementioned issues, existing patent (CN209624742U) discloses a motor testing instrument, comprising a support layer, an electric slide rail, an electric slider, a support block, an opening, a worktable, hydraulic cylinders, and a testing instrument. The motor is placed on the support layer, and then the electric slide rail is activated. When the electric slide rail operates, the electric slider moves accordingly, causing the support block to move as well. When the support block moves, it enters the opening, thus placing the motor at the top of the worktable. Then, two hydraulic cylinders are activated, causing the testing instrument to move downwards and perform testing on the motor, facilitating the testing of motors of different sizes and specifications.

[0004] However, in the aforementioned existing technologies, the detection devices are weak in multi-physics field coupling sensing, making it difficult to fully acquire multi-dimensional information about the motor's operating state. This limits the accuracy and comprehensiveness of the detection results, thereby affecting the device's detection effect on the motor. Utility Model Content

[0005] The purpose of this invention is to provide a multi-dimensional motor detection device based on multi-physics field coupling sensing. This invention solves the technical problem that existing detection devices have weak multi-physics field coupling sensing capabilities, making it difficult to comprehensively acquire multi-dimensional information about the motor's operating state. This results in limitations on the accuracy and comprehensiveness of the detection results, thus affecting the device's detection effect on the motor.

[0006] To achieve the above objectives, this utility model employs a multi-physics field coupled sensing motor multi-dimensional detection device, comprising a base frame and a detection mechanism; the detection mechanism includes a temperature detector, a laser vibration meter, a torque sensor, a top plate, a telescopic rod, a base plate, a lifting component, and a fixing component.

The fixed plate is fixedly connected to the moving block and slidably connected to the base plate. The driving component is connected to the base plate and to the moving block.

The dual-axis motor is fixedly connected to the base plate, and the output shaft of the dual-axis motor is connected to the driving rod.

[0009] The lifting component includes a support block, a slider, and a moving part. The support block is rotatably connected to the base plate and is located on the side of the base plate away from the top plate. The slider is slidably connected to the base frame and rotatably connected to the support block. The moving part is connected to the base frame and to the slider.

[0011] This invention discloses a multi-physics field coupled sensing motor multi-dimensional detection device. The motor is placed on a base plate. A dual-axis motor drives a drive rod to rotate inside the base plate. The drive rod engages with a moving block, causing the moving block to move. The moving block moves a fixed plate on the base plate, clamping the motor on both sides and fixing it to the base plate. A moving motor drives a moving rod to rotate on a base frame.
