Description

Technical Field

[0001] This utility model relates to the field of frameless motor speed and torque testing technology, and in particular to a novel frameless motor speed and torque testing platform. Background Technology

[0002] Currently, the application of frameless motors has expanded from industrial automation to cutting-edge fields such as bionics and aerospace. With the explosive growth in demand for humanoid robots and semiconductor equipment, the market size will further expand.

[0003] Existing torque testing platforms are mostly framed motor testing platforms. The fixing methods of framed motors and frameless motors are completely different. Framed motors have fixing holes, while frameless motors do not. When testing different models of motors, existing testing platforms require adjustment of the coaxiality between the motor shaft and the torque sensor after each replacement due to the different dimensions of the motors. The coaxiality requirements are very high, making the coaxiality adjustment complex and time-consuming. Therefore, we propose a new frameless motor speed and torque testing platform.

The fixed base is installed on the three-axis displacement platform, and the fixed upper cover is detachably installed on the fixed base. The frameless motor can be placed on the fixed base and fixed by the fixed upper cover.

[0029] Reference Figure 1 , Figure 2 as well as Figure 3A novel frameless motor speed and torque testing platform is provided. This novel frameless motor speed and torque testing platform includes a testing platform 1. A dynamic torque sensor 2 is installed on the top of the testing platform 1 via an I-beam support column. The dynamic torque sensor 2 can collect data such as torque, speed, and power. A magnetic powder brake 3 is installed on the top of the testing platform 1. The magnetic powder brake 3 has a torque adjustment function, which can be used to adjust the test torque. A plum blossom coupling 4 is installed on the dynamic torque sensor 2. The plum blossom coupling 4 can compensate for the coaxiality deviation. The dynamic torque sensor 2 is located between the magnetic powder brake 3 and the plum blossom coupling 4. The dynamic torque sensor 2, the magnetic powder brake 3, and the plum blossom coupling 4 are set to be coaxial.

[0030] The top of the test platform 1 is supported by a cross roller bearing 5. The cross roller bearing 5 has the characteristics of multi-directional load, high rigidity and precision motion. The multi-directional load can offset the deviation of the coaxiality between the stepped shaft 6 and the motor. The high rigidity and precision motion can ensure the accuracy of the test. One side of the cross roller bearing 5 is connected to the plum blossom coupling 4, and the other side of the cross roller bearing 5 is equipped with the stepped shaft 6. The design of the stepped shaft 6 can be adapted to different models of motors. The coaxiality of the plum blossom coupling 4, the cross roller bearing 5 and the stepped shaft 6 is set.

[0031] A three-axis displacement platform 7 is installed on the top of the test platform 1. A fixing device is installed on the three-axis displacement platform 7, and a frameless motor 10 is placed on the fixing device. The three-axis displacement platform 7 is used to adjust the frameless motor 10 in the front, back, up, down, left and right directions, which makes the coaxiality adjustment more convenient and precise.

[0032] The fixing device includes a fixed base 8 and a fixed upper cover 9. The fixed base 8 is installed on the three-axis displacement platform 7, and the fixed upper cover 9 is detachably installed on the fixed base 8. The frameless motor 10 can be placed on the fixed base 8 and can be fixed by the fixed upper cover 9.

[0033] In practical use, by fixing the dynamic torque sensor 2 and the magnetic powder brake 3 on the test platform 1 and ensuring their coaxiality, then connecting the cross roller bearing 5 and the stepped shaft 6 with the plum blossom coupling 4 and fixing them on the test platform 1, then placing the frameless motor 10 into the fixing device, and adjusting the coaxiality of the frameless motor 10 with the stepped shaft 6 through the three-axis displacement platform 7 and fixing it, the experimental platform can be built. This makes it convenient to build the experimental platform and the operation is simple and quick.

[0034] When performing torque testing on the frameless motor 10, the torque value of the magnetic powder brake 3 is first set. The torque value is set according to the parameters of the frameless motor 10 under test. Then, the frameless motor 10 is started for testing. During the test, the required data can be collected through the dynamic torque sensor 2. At the same time, due to the design of the stepped shaft 6, when changing to different models of motors, only the motor fixing device needs to be replaced. The rest of the parts do not need to be adjusted. After the fixing device is replaced, the coaxiality can be adjusted by using the three-axis displacement platform 7, which can improve the accuracy of coaxiality and reduce the adjustment time.

[0035] This invention uses a frameless motor 10 fixing device to fix the motor, and uses a three-axis displacement platform 7 and crossed roller bearings 5 ​​to optimize the coaxiality adjustment, so as to ensure the accuracy and efficiency of motor testing.

[0036] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
