[0022] like Figure 1 and Figure 2As shown, a tool for driver testing includes a base 12 and a rotating disk 1. The base 12 is a rotating body structure. A flange is provided at the bottom of the base 12 to facilitate the placement of the base 12. A cavity for wiring is provided at the bottom of the base 12.

The mounting groove 5 is a circular groove. The top of the mounting groove 5 is fitted with a stator 4. In this embodiment, a flange is provided on the outer wall of the stator 4, and a hole is opened and closed on the flange. The stator 4 and the top of the base 12 are locked by screws installed in the hole. A through hole is opened at the bottom of the mounting groove 5, which is connected to the cavity. An encoder 11 is installed at the bottom of the boss. In this embodiment, the encoder 11 is a commercially available product, which is mainly used to test the position, speed and angle of the rotating part. A rotating shaft 2 is provided at the bottom of the rotating disk 1. The bottom of the rotating shaft 2 is connected to the rotor 3. The rotor 3 is located on the inner side of the stator 4. The bottom of the rotor 3 is connected to the rotor shaft 6. The bottom of the rotor shaft 6 is connected to the code disk shaft 10. The bottom of the code disk shaft 10 passes through the through hole, and the bottom of the code disk shaft 10 is located in the inner cavity of the encoder 11. Therefore, when the rotor 3 rotates, the rotor 3 Then the rotating disk 1 is driven to rotate, and the rotor 3 also drives the code disk shaft 10 to rotate through the rotor shaft 6. Therefore, the rotating disk 1, the rotating shaft 2, the rotor 3, the rotor shaft 6, and the code disk shaft 10 rotate synchronously. Therefore, when the encoder 11 detects the position, speed and angle of the code disk shaft 10, it can reflect the position, speed and angle of the rotating disk 1. In this embodiment, the bottom of the mounting groove 5 is provided with a convex ring 9 protruding upward, the code disk shaft 10 is located on the inner side of the convex ring 9, and a bearing 7 is installed between the code disk shaft 10 and the convex ring 9, thereby ensuring the coaxiality of the rotation of the rotating disk 1, the rotating shaft 2, the rotor 3, the rotor shaft 6, and the code disk shaft 10. When testing, The connection terminals of the rotor 3, stator 4 and encoder 11 are connected to the driver to be tested, a load object is placed on the rotating disk 1, and then the driver to be tested drives the rotor 3 to rotate relative to the stator 4, so that the position, speed and angle parameters of the code disk shaft 10 are detected by the encoder 11, and the encoder 11 feeds back the detected parameters to the driver, thereby testing the performance of the driver to be tested. During the test, different loads can be applied to the rotating disk 1 to test the driver, and the connection terminals of the rotor 3, stator 4 and encoder 11 are universal connection terminals, which can be connected to drivers of different models, thereby testing drivers of different models.

A pressure ring 17 is provided on the outer wall of the code disk shaft 10, and the bottom of the pressure ring 17 abuts against the inner ring of the bearing 7, thereby ensuring the reliability of the installation of the bearing 7.

[0024] In this embodiment, the rotating disk 1 and the rotating shaft 2 are connected by a plurality of locking screws, and the locking screws extend axially downward and pass through the rotor 3 and are locked with the rotor shaft 6. Therefore, the rotating disk 1, the rotating shaft 2, the rotor 3 and the rotor shaft 6 are locked by a set of locking screws, which makes their connection convenient. At the same time, it also makes it unnecessary to open too many holes on the rotating disk 1, the rotating shaft 2, the rotor 3 and the rotor shaft 6, thereby reducing the processing difficulty and reducing the space occupied by the overall structure.

[0025] In this embodiment, if Figure 2 As shown, a wire threading hole 13 is opened on the side wall of the cavity at the bottom of the base 12, so as to facilitate the installation of the wires of various components of the tooling.

During the test, different loads can be applied to the rotating disk 1 to test the driver, and the connection terminals of the rotor 3, stator 4 and encoder 11 are universal connection terminals, which can be connected to drivers of different models, thereby testing drivers of different models.
