Description
Technical Field
[0001] The utility model relates to the technical field of motor testing, in particular to a motor testing device capable of simulating torque and radial load at the same time. Background Art
[0002] In the field of motor testing, accurate evaluation of motor performance is crucial to ensuring motor quality and optimizing design. Traditional motor testing methods and equipment can often only fully reflect the complex load conditions faced by the motor in the actual working process under a single working condition. The existing test methods and equipment for motor performance detection can only perform torque loading tests or radial loading tests on a single device. Although some research has been conducted on the market based on this defect, most of the developed equipment still has certain limitations, such as single test function, complex operation, and high cost. Summary of the invention
[0003] In view of the above-mentioned deficiencies, the utility model provides a motor test torque loading and radial loading device which has a simple structure, is easy to operate and has a low cost.
[0004] In order to achieve the above purpose, the utility model adopts a motor test torque loading and radial force loading device, including an operating table, a clamping position of the motor to be tested limited on the operating table, a torque loading mechanism for torque loading, and a radial loading mechanism for radial loading. The torque loading mechanism includes a dynamometer mechanism, and the dynamometer mechanism has a built-in dynamometer force sensor. The output shaft of the dynamometer mechanism extends to one side of the clamping position of the motor to be tested, and is used for connecting the external motor to be tested to the clamping position of the motor to be tested after the upper limit is set, and forming a torque loading output, and through the built-in dynamometer force sensor of the dynamometer mechanism, the torque loading force is adjusted;
[0005] The radial loading mechanism includes a servo drive mechanism, a loading rod, and a radial force sensor. One end of the loading rod extends in the circumferential direction of the external motor to be tested after the external motor to be tested is limited at the clamping position of the motor to be tested during the test phase. The other end of the loading rod is connected to the servo drive mechanism and outputs the loading force, and the radial loading force is adjusted through the radial force sensor. The dynamometer mechanism is a dynamometer motor, and the servo drive mechanism is a servo motor.
[0006] The utility model is further configured such that the clamping position of the motor to be tested and the dynamometer mechanism are both distributed at the upper end of the operating table, and the output end of the dynamometer mechanism and the output shaft of the external motor to be tested clamped on the clamping position of the motor to be tested are distributed on the same straight line, the radial force sensor is connected to the lower end of the operating table, the servo drive mechanism is connected to the radial force sensor, and the loading rod connected to the servo drive mechanism passes through the radial force sensor and extends to the upper end of the operating table; the loading device also includes a coupling, through which the output shaft of the dynamometer mechanism and the external motor to be tested are connected after the clamping position of the motor to be tested is limited during the test phase.
[0007] Through the above arrangement, the clamping position of the motor to be tested, the dynamometer mechanism and the radial loading mechanism can be reliably distributed on the operating table, thereby further ensuring the reliability of the design and avoiding mutual interference due to improper design. At the same time, the output end of the dynamometer mechanism and the output shaft of the external motor to be tested can be reliably transmitted.
[0008] The utility model is further configured that the loading device also includes a radial loading connection component, which is sleeved on the output shaft of the external motor to be tested, and the side of the radial loading connection component is provided with a component adapted to the loading rod, and a detachable connection is formed between the loading rod and the side of the radial loading connection component; the radial loading connection component is a sleeve used for radial loading force.
[0009] Through the above arrangement, since the loading rod and the output shaft on the radial loading mechanism are both shaft structures, when a radial loading connection assembly is involved, the loading rod and the output shaft can be reliably connected, and it can be avoided that when the loading rod acts on the output shaft, the top of the loading rod and the circumferential surface of the output shaft are not easy to touch, or even if they touch, when the loading force changes, the rod top will not slip, and the output shaft will not be damaged due to the action of the loading rod, thereby ensuring the reliability of the design and test.
[0010] The utility model is further configured such that the dynamometer mechanism includes a mounting base connected to an operating table, a sensor box connected to the mounting base, and a torque output mechanism arranged toward a clamping position of the motor to be tested; the output end on the dynamometer mechanism is distributed on a side of the torque output mechanism away from the sensor box, and the dynamometer force sensor built into the dynamometer mechanism is distributed in the sensor box.
[0011] Through the above, the dynamometer mechanism is highly reliably arranged on the operating table, and the dynamometer force sensor in the dynamometer mechanism also achieves a correspondingly highly reliable distribution, thereby further ensuring that the dynamometer mechanism part can be highly reliably arranged on the loading device, thereby ensuring the reliability of the design of the loading device.
[0012] Compared with the prior art, the beneficial effect of the utility model is that: the loading device involves a torque loading mechanism and a radial loading mechanism, thereby integrating the torque loading test and the radial loading test of the motor, thereby greatly improving the convenience compared with the existing independent installation and debugging using separate equipment. In addition, the test device involved in the utility model involves the torque loading mechanism in the dynamometer motor, and integrates a high-precision force sensor in the dynamometer motor, thereby achieving real-time monitoring and adjustment of the simulated torque applied to the motor output shaft during the torque loading test phase, thereby ensuring the accuracy of the test, and the radial loading part involves a servo motor, and a force sensor that can also achieve high precision is installed on the loading rod, thereby achieving During the loading test stage, the simulated radial force applied to the front end shaft of the motor can be monitored and adjusted in real time to ensure the stability and controllability of the force during the test. The synchronous test device also realizes precise testing and regulation of the motor torque and radial load, providing an effective means for motor performance evaluation and optimization. It has high practicality and economy, and is suitable for motor manufacturing, research and development, and quality control. At the same time, the test device involved in the utility model has a compact structure. Compared with the existing test of torque and radial load, which requires at least two devices or equipment, the space occupied can be greatly reduced, and the need for multiple clamping and debugging is eliminated compared to the traditional one, so that the operation process is simplified, the cost is reduced, and the work efficiency is greatly improved.
[0013] Before the test begins, the target torque value and target radial force value can be set according to the test requirements. Then, the test device is started, the dynamometer motor starts working, and the torque applied to the motor output shaft is adjusted according to the feedback signal of the force sensor until it reaches and stabilizes at the target torque value. At the same time, the servo cylinder also starts working, and by adjusting the position and strength of the loading rod, the radial force applied by the loading rod on the front end shaft of the motor gradually approaches and stabilizes at the target radial force value.
