Description

Technical Field

[0001] The present application relates to the field of motor technology, and in particular to a motor tester. Background Art

[0002] A motor tester is an important device used to evaluate and diagnose motor performance. It provides detailed information on the motor's operating status and potential problems through various testing methods, such as electrical parameter measurement, operating status monitoring, and vibration analysis.

[0003] Among them, the torque test in the motor tester is a key link in evaluating motor performance. It is directly related to the motor's load capacity, power output characteristics and operating stability. The basic principle of torque testing is based on the principle of torque balance, that is, measuring the product of the force acting on the object being tested (here, the motor output shaft) and the lever arm to calculate the torque.

[0004] For example, the patent with publication number CN221595195U discloses a dynamic torque testing device. This patent uses a strain beam that is symmetrical up and down and has a waist-shaped hole in the middle. When the sensor is affected by bending moment, it can transition well and reduce the influence of bending moment on torque. In addition, this torque sensor is equipped with a digital board on the shaft, which can realize wireless power supply and wireless transmission. The installation and testing are very convenient, which solves the problem of low test accuracy caused by poor concentricity of traditional torque testing equipment.

[0005] During the implementation of the above-mentioned patent, different motors may be tested. However, there may be large differences in size, weight and surface material between different motors, resulting in the inability to adjust the clamping force of the motor to the appropriate level. This may cause the motor to be subject to additional constraints or pressure during the test, thereby affecting the accuracy of the torque test results.

[0006] Therefore, it is necessary to provide a motor tester to solve the above problems.

[0007] It should be noted that the above information disclosed in this Background section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute prior art. Summary of the Invention

[0038] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0039] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0040] like Figure 1-Figure 4 As shown, the present application provides a motor tester, comprising a frame 1, and a lifting mechanism 2 fixedly arranged on one side of the upper end of the frame 1, the lifting mechanism 2 is used to adjust the tester to adapt to motors of different sizes to be tested;

[0041] The lifting mechanism 2 includes a transmission assembly fixedly arranged on one side of the upper end of the frame 1, and the transmission assembly includes a plurality of mounting blocks 21 fixedly arranged on one side of the upper end of the frame 1, and a slide rail 22 fixedly arranged on the mounting block 21;

[0042] A slider 25 is slidably connected to the upper end of the slide rail 22. A motor 26 is fixedly installed on one side of one set of slide rails 22. A lead screw 24 is fixedly installed on the output end of the motor 26. The slider 25 is transmission-connected to the lead screw 24. When the motor 26 is operated, the slider 25 can be driven to move along the direction of the slide rail 22.

[0043] Stoppers 23 are fixedly provided at both ends of the slide rail 22 to limit the position of the slider 25 and prevent it from leaving the slide rail 22. When the slider 25 contacts the stoppers 23, the slider 25 stops moving.

[0044] At the same time, the mounting platform 3 is fixedly provided on the multiple sets of sliders 25, so that when the motor 26 is operated, the sliders 25 can be driven to move vertically along the direction of the slide rails 22, so that the sliders 25 can stably drive the mounting platform 3 to move, thereby achieving the purpose of lifting and lowering the mounting platform 3;

[0045] A test mechanism 4 is fixedly provided at the upper end of the frame 1. The test mechanism 4 is used to test the motor under test. The test mechanism 4 includes a mounting plate 40 fixedly provided at a position on the upper end of the frame 1 away from the mounting platform 3. A brake 41 is fixedly provided at the upper end of the mounting plate 40. For example, patent publication number CN212985854U discloses a magnetic powder brake device. The brake 41 is used to apply a load to the motor under test during the test process, thereby simulating actual working conditions to facilitate the performance evaluation of the motor under test.

[0046] A coupling 42 is fixedly provided at the output end of the brake 41. A support platform 45 is fixedly provided at the upper end of the mounting plate 40 near the brake 41. A sensor 43 is fixedly provided at the upper end of the support platform 45. The input end of the sensor 43 is fixedly connected to the coupling 42 to facilitate monitoring and recording of key parameters during the test.

[0047] like Figure 4-Figure 6 As shown, in order to ensure that the motor under test can be stably tested during the test process, a fixing mechanism 47 is fixedly provided on the mounting platform 3;

[0048] The fixing mechanism 47 includes a connecting plate 471 fixedly mounted on the mounting platform 3. A fixing sleeve 476 is fixedly mounted on both ends of the connecting plate 471. A sliding plate 477 is slidably mounted on the fixing sleeve 476. A plurality of positioning holes 475 are correspondingly formed on the sliding plate 477 and the fixing sleeve 476.

[0049] A fixing bolt 474 is threadedly connected to the positioning hole 475, so that the sliding plate 477 can be positioned by rotating the fixing bolt 474 to fit the fixing sleeve 476. When the fixing bolt 474 is rotated away from the fixing sleeve 476, the position of the sliding plate 477 can be adjusted, thereby adapting to motors of different sizes to be tested by adjusting the position of the sliding plate 477.

[0050] At the same time, a support plate 479 is fixedly provided on the upper end of the two sets of sliding plates 477, and in order to adapt to the clamping force of different motors to be tested, a clamping assembly is fixedly provided between the support plate 479 and the connecting plate 471 (refer to Figure 6 ), the clamping assembly is used to adaptively clamp different motors to be tested, thereby improving test efficiency;

[0051] The clamping assembly includes a support column 472 fixedly provided at the middle position of the upper end of the connecting plate 471, and a lower clamping plate 473 fixedly provided at the upper end of the support column 472, and the lower clamping plate 473 is used to directly contact the motor to be tested;

[0052] At the same time, a cylinder 478 is fixedly installed on the upper end of the support plate 479. The output end of the cylinder 478 passes through the support plate 479 and is fixedly connected to the pressure plate 481.

[0053] The lower end of the pressure plate 481 is fixedly provided with a plurality of pressure rods 482, which are fixedly connected to the pressure plate 481 so as to transmit the downward pressure force more evenly and stably. The pressure rods 482 are divided into fixed rods fixedly connected to the pressure plate 481 and telescopic rods away from the pressure rods 482. The telescopic rods convert power into pressure on the motor to be tested through telescopic movement.

[0054] A spring 483 is provided on the outside of the telescopic rod. The spring 483 is used to buffer the pressure when the pressure is released. The spring 483 can be adaptively adjusted to clamp the motor according to the different product models of the motor to be tested and the pressure required by each product model.

[0055] The fixing rod is used to transfer pressure stably and evenly to the motor under test for clamping operation, so as to maintain stability during testing. A plurality of upper clamping plates 485 are fixedly provided at the lower end of the fixing rod. The upper clamping plates 485 are used to clamp the motor under test directly with the lower clamping plates 473 under the push of the pressure rod 482.

[0056] Before the test begins, the motor to be tested is placed on the lower clamping plate 473. At this time, the control cylinder 478 applies a steady pressure to the pressure plate 481, and the pressure rod 482 then descends evenly. When the upper clamping plate 485 is pushed by the pressure rod 482 to contact the surface of the motor to be tested, the telescopic rod in the pressure rod 482 retracts under the pressure. At this time, the spring 483 sleeved on the outer ring begins to compress. According to the clamping force required by the motor to be tested, the spring 483 automatically adjusts its compression amount to adapt to the clamping force required by the motor to be tested, thereby clamping it.

[0057] Then, the motor to be tested can be adjusted to a coaxial position with the coupling 42 by the lifting mechanism 2, and the output end of the motor to be tested can be fixedly connected to the coupling 42;

[0058] At this time, the brake 41 is activated to test the torque of the motor to be tested, and the sensor 43 is used to monitor, record and export relevant data.

[0059] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
