Description

Technical Field

[0001] The utility model belongs to the technical field of servo drivers, and in particular relates to a novel testing device for servo drivers. Background Art

[0002] A servo drive is a controller used to control a servo motor. It is part of a servo system and is mainly used in high-precision positioning systems. It generally controls the servo motor in three ways: position, speed, and torque to achieve high-precision transmission system positioning. It is a high-end product of transmission technology.

[0003] The driver needs to be inspected and tested before leaving the factory. The test devices mainly include the following: a test device using servo driver-motor mutual feedback and drag, a test device using an adjustable simulated load, a test device using an actuator motor but no load, a test device using an actuator motor to drag an inherent load, and a test device using an online testing method. The present invention proposes a test device using an actuator motor to drag an inherent load. For this test device, the load uses the inherent load of the system under test, so the test process is close to the actual working condition of the servo driver, and the test result is relatively accurate. However, at present, this test device is too cumbersome and difficult to operate, so that the test is time-consuming and laborious; some are too complicated, occupy a large area, and are costly; and the test process cannot be visualized for human-computer interaction, which is not very convenient to use. Therefore, we provide a new test device for servo drivers. Utility Model Content

An alarm light 3 is provided on the top of the test bench 11. The setting of the display screen facilitates human-computer interaction and can monitor the operating status of the driver body 2, such as operation, end of aging, abnormal aging suspension, and operating time monitoring. When an abnormal phenomenon occurs during the test, an alarm is given through the alarm light 3, and the power supply is actively cut off and recorded. A three-layer driver carrier board 7 is provided on the test bench 11, and more than a dozen driver bodies 2 can be placed on each layer of the driver carrier board 7. A wire groove 6 and a guide rail socket 5 are installed on the driver carrier board 7. Figure 1 As shown, an actuator 1 is provided on the back of the test bench 11, and the actuator 1 is composed of a motor mounting plate 1-1, a protective cover 1-2, a motor 1-3 and an inertia disk 1-4. A corresponding number of servo motors are installed on the motor mounting plate 1-1. Because the motor mounting plate 1-1 is used to install the corresponding 1-3, the inherent load inertia disk 1-4 is installed on the shaft end of the motor 1-3 to simulate the actual use condition of the driver. Secondly, because the protective cover 1-2 is fixed to the motor mounting plate 1-1 by screws, it is used to protect the rotating load and prevent the load from being thrown out. At the same time, it plays an isolation and protection role for the operator to avoid touching the rotating load. Because the driver carrier plate 7 is compatible with driver bodies 2 of different models and sizes, and the driver carrier plate 7 is placed at a certain angle, it is easy to operate and take the driver, which is convenient and fast.

[0023] See Figure 1 As shown, a control cabinet 8 and an electrical cabinet 9 are respectively provided at the bottom of the test bench 11. Through the arrangement of the control cabinet 8 and the electrical cabinet 9, relevant controllers and electrical equipment can be installed inside the control cabinet 8 and the electrical cabinet 9 to facilitate subsequent control of the device. Figure 1As shown, the four sides of the bottom of the test bench 11 are movably connected with the Forma wheels 10, and the number of the Forma wheels 10 is four. Figure 1 As shown, by providing the Forma wheel 10, the purpose of easy movement is achieved, the flexibility of the device is improved, and the device can be replaced to different test sites.

[0024] When in use, firstly, the test bench 11 is moved to the specified position through the Forma wheel 10, and then the corresponding number of 1-3 is installed on the motor mounting plate 1-1, and the inherent load inertia disk 1-4 is installed through the shaft end of the motor 1-3 to simulate the actual use condition of the drive. Secondly, because the protective cover 1-2 is fixed to the motor mounting plate 1-1 by screws, it is used to protect the rotating load and prevent the load from being thrown out. At the same time, it plays an isolation and protection role for the operator to avoid touching the rotating load.

[0025] The test data can be displayed through the display screen on the display screen mounting plate 4. The display screen has a touch function to realize human-computer interaction, such as operation, aging end, aging abnormality pause and running time monitoring. When an abnormal phenomenon occurs during the test, an alarm is given through the alarm light 3, and the power supply and recording are actively cut off. Finally, because the driver carrier board 7 is compatible with driver bodies 2 of different models and sizes, and the driver carrier board 7 is placed at a certain angle, it is easy to operate and take the driver, which is convenient and quick.
