Description

Technical Field

[0001] The present invention relates to the technical field of motors, and in particular to a method for detecting motor torque. Background Art

[0002] As the most basic and important parameter of motor performance, motor torque must be calculated in the early stage of design and must be measured after manufacturing. This is especially true for servos, which are a type of motor. Servos are an indispensable and important part of intelligent robots, model airplanes, cars and other model toys. They can be used to transfer the control surface of mechanical devices, adjust the indicators of electronic equipment, etc. During the use of servos, the torque of the servos needs to be measured to evaluate their performance. However, due to the testing principle of the torque tester and the limitations of the torque test bench itself, there are certain restrictions on the shape and size of the specimen, so different servos require different torque benches.

[0003] Currently, the main way to detect the torque of the servo is to purchase the corresponding torque bench for testing. Due to the large torque range of the motor and the compact location of the test area in the factory, each purchase of a new torque test bench requires specialized personnel to learn, which is time-consuming and costly, and is not suitable for torque testing of multiple types of motors.

[0004] Moreover, the servo torque testers currently on the market are complex in structure, expensive, and difficult to maintain, so it is now necessary to devise a torque detection method that is quick, convenient, simple in structure, and accurate in testing. Summary of the invention

[0005] The object of the present invention is to provide a method for detecting motor torque, comprising the following steps:

[0006] 1) Build a torque table, including a torque rod, table frame, torque sensor, servo installation tooling, and torque adjustment plate.

[0007] 2) Fix the servo on the torque table.

[0008] 3) Use the manual fixed-point torsion bar distance method to adjust the torque bar position.

[0009] 4) Perform torque test on the servo.

[0010] 5) The servo torque is transmitted to the torque sensor through the torque rod. The torque sensor uploads the servo torque to the PC to obtain torque data.

[0011] Furthermore, the steering gear is connected and fixed on the torque platform through a steering gear installation tool.

[0012] Further, the steps of the manual fixed-point torsion bar distance method are as follows:

[0013] By manually turning the torque adjustment disk, the position of the torque rod is adjusted so that the torque on the torque rod reaches the specified value.

[0014] Furthermore, the adjustment of the torque magnitude is achieved by adjusting the length of the torque rod.

[0015] Furthermore, the torque rod, torque sensor, steering gear installation tooling, and torque adjustment plate are all placed on a table frame.

[0016] Furthermore, the torque sensor is connected to the PC via a wired or wireless method.

[0017] Furthermore, the length of the torque rod is adjustable.

[0018] Furthermore, the PC performs denoising on the steering gear torque.

[0019] The technical effect of the present invention is unquestionable. The present invention has a simple structure, simple operation, and low manufacturing cost. It can be used for most steering gear torque detection, saving money and time costs, and also improving detection efficiency.

[0020] The invention can adjust the length of the torque rod, thereby adapting to steering gears of different models.

[0021] The invention has a simple structure and a small volume, and the detection is accurate, convenient and fast. BRIEF DESCRIPTION OF THE DRAWINGS
