It adjusts its output in real time through a closed-loop control system to ensure accurate motion response to control signals.

[0003] The output end of the servo motor is the torque shaft. As the power output end, the torque shaft usually needs to be tested for runout, concentricity between the torque shaft and the flange, and perpendicularity between the torque shaft and the flange mounting surface. Existing testing equipment can usually only test one step at a time and cannot test multiple parameters simultaneously. Utility Model Content

[0027] This embodiment provides a mechanism for measuring the torque of a motor and detecting the concentricity and perpendicularity of a flange, including:

[0028] Workbench 1;

[0029] The feeding mechanism 2 is slidably disposed on the worktable 1 and used to clamp the servo motor 3, so that the torque axis 30 of the servo motor 3 is vertically upward. The feeding mechanism 2 includes a support base 20, which is used to support and place the servo motor 3. The support base 20 is provided with a gripper cylinder 21 and a first gripper 22. The first gripper 22 is driven by the gripper cylinder 21 to clamp the outside of the servo motor 3.

[0030] The first support 4 is mounted on the workbench 1;

[0031] A floating mechanism 5 is mounted on the first support 4 and located above the feeding mechanism 2. It is used to clamp the torque shaft 30 of the servo motor 3 and enable its rotation. Specifically, the floating mechanism 5 includes a first motor 50 fixedly mounted on the top of the first support 4, and a bushing 51 fixed and passing through the first support 4. A rotating shaft 52 is rotatably mounted inside the bushing 51. The upper end of the rotating shaft 52 is driven and connected to the first motor 50, and the lower end is fixedly connected to a second gripper 53 for clamping the torque shaft 30. A support base 20 is fixed at the bottom end of the bushing 51. The first detection mechanism 6 and the second detection mechanism 7 are located at the lower ends of the support base 20. During operation, the first motor 50 drives the rotating shaft 52 to rotate. The second gripper 53 is an existing pneumatic gripper, and its structure and principle will not be described in detail. The feeding mechanism 2 drives the servo motor 3 to move upward, so that the second gripper 53 clamps the torque shaft 30. The feeding mechanism 2 can move horizontally and vertically. Its motion mechanism is an existing sliding mechanism, which will not be described in detail in this embodiment.

[0032] The first detection mechanism 6 and the second detection mechanism 7 are provided on the floating mechanism 5 and are located on both sides of the floating mechanism 5 respectively, and are used to detect the concentricity of the torque shaft 30 and the flange 31 and the perpendicularity of the torque shaft 30 and the flange mounting surface 32 respectively.

[0033] The third testing mechanism 8 is located on the workbench 1 and is used to test the runout of the torque shaft 30.

[0034] In this embodiment, the first detection mechanism 6 further includes a first fixed base 60, a first sensor 61, and a first slider 62. The bottom of the support base 20 is provided with a guide rail 200. The first slider 62 is slidably connected to the guide rail 200. The first fixed base 60 is fixed to the first slider 62. The first sensor 61 is located at the bottom of the first fixed base 60 and its detection end abuts against the outer circular surface of the flange 31 on the servo motor 3. The support base 20 is provided with fixing blocks 63 at both ends. The fixing blocks 63 are provided with pins 64. The pins 64 and the first fixed base 60 are threadedly connected. By rotating the pins 64, the distance between the first fixed base 60 and the second gripper 53 can be adjusted to adapt to the detection of torque shafts 30 of different diameters. The second gripper 53 drives the servo motor 3 to rotate. The first sensor 61 detects the concentricity between the outer circular surface of the flange 31 and the torque shaft 30.

[0035] In this embodiment, the second detection mechanism 7 further includes a second slider 70, a second fixed base 71, and a second sensor 72. The second fixed base 71 is slidably connected to the guide rail 200 via the second slider 70. The second sensor 72 is fixed to the second fixed base 71, and its detection end abuts against the flange mounting surface 32 of the servo motor 3. The end of the support base 20 is threadedly connected to the second fixed base 71 via a pin 64. Similarly, the distance between the second fixed base 71 and the second gripper 53 is changed via the pin 64. During operation, the second sensor 72 detects the perpendicularity of the flange mounting surface 32 to the torque axis 30.

[0036] Furthermore, the third detection mechanism 8 includes a second support 80, on which a lead screw drive assembly 81 is mounted. A support plate 82 is slidably connected to the lead screw drive assembly 81, and a third sensor 83 is mounted on the support plate 82. The detection end of the third sensor 83 abuts against the outer surface of the torque shaft 30. The lead screw drive assembly 81 is also existing; as can be seen from the attached drawings, it is a conventional lead screw driven by a lead screw motor and a screw-slider threaded transmission. Therefore, the specific structure of the lead screw drive assembly 81 will not be described in detail in this embodiment. The runout of the torque shaft 30 is detected by the third sensor 83. In this embodiment, the first sensor 61, the second sensor 72, and the third sensor 83 are all existing contact sensors, which will not be described in detail. These detection parameters are directly output by connecting to a detection instrument, which is also existing, and therefore will not be described in detail. This mechanism can perform multiple program detections simultaneously with the same reference, resulting in high detection accuracy and efficiency.

[0037] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
