After the testing is completed, the equipment or motor needs to be continuously replaced and installed, which may bring certain cumbersome problems.
[0004] In summary, there is an urgent need for an encoder simulation testing device that can be used for encoders of different types or sizes to solve the above problems. Content of the Utility Model

Detailed implementation manners
[0021] The present utility model will be further described below in conjunction with the attached drawings and embodiments.
[0022] Embodiment 1: An encoder simulation test device, as Figures 1 - 3 shown, includes a support frame 1, a placement table 2, a protective cover 3, a placement plate 5, a driver 6, a three-phase AC motor 7, an encoder 701, a connecting wire 8, a lifting plate 9 and a guiding plate 10. A placement table 2 is placed on the support frame 1. A protective cover 3 for isolating the placement table 2 is fixedly connected to the support frame 1. Three placement plates 5 are welded on the placement table 2. A driver 6 for testing equipment is provided on the left placement plate 5 by screws. Different models of three-phase AC motors 7 are provided on all three placement plates 5 by screws. An encoder 701 is fixedly connected to the output shaft of the three-phase AC motor 7 through a coupling. A connecting wire 8 is fixedly connected to the connection end of the driver 6, and the connecting wire 8 is connected to the three-phase AC motor 7. A lifting plate 9 is fixedly connected to the bottom of the placement table 2. Two guiding plates 10 are fixedly connected to the rear side of the support frame 1, and the lifting plate 9 slides on the guiding plates 10.
[0023] When the staff needs to conduct encoder simulation tests on the three-phase AC motor 7, they can install three-phase AC motors 7 of different models on the placement plate 5 through screws, so that the connecting wire 8 can be quickly connected to the three-phase AC motor 7. And through the pre-established driver 6 project program, set the operating speed of the three-phase AC motor 7 and start the three-phase AC motor 7. After the staff starts the driver 6, the three-phase AC motor 7 operates according to the instructions set by the driver 6. As the three-phase AC motor 7 operates, its output shaft drives the encoder 701 to rotate. During this process, the encoder 701 can detect the operating speed of the three-phase AC motor 7 and feedback the detected data to the driver 6. Use the STARTER software of the industrial control PC to connect to the driver 6. At the same time, the externally connected industrial control PC will be connected to the driver 6, and the status data of the three-phase AC motor 7 and its encoder 701 can be obtained from the driver 6, and then monitoring and data analysis can be carried out. The industrial control PC records the feedback data of the encoder 701 to judge the working reliability of the encoder 701. And when it is necessary to conduct encoder simulation tests on other types of three-phase AC motors 7, the staff first turns off the driver 6. Subsequently, the staff only needs to disconnect the connecting wire 8 from the current three-phase AC motor 7 and then reconnect it to another three-phase AC motor 7, so that different types of three-phase AC motors 7 can be detected without changing or moving the position of the driver 6.
[0024] Embodiment 2: On the basis of Embodiment 1, as Figure 3 and Figure 4 shown, it further includes a servo motor 11, a first protective housing 12, a guide rod 13, a rack 1301 and a gear 14. The right side of the rear part of the support frame 1 is installed with a servo motor 11 through screws. A first protective housing 12 for protecting the servo motor 11 is welded on the right side of the support frame 1. A guide rod 13 is fixedly connected to the output shaft of the servo motor 11. Racks 1301 are welded on both the left and right sides of the lifting plate 9. Two gears 14 are fixedly connected to the guide rod 13, and the gears 14 are meshed with the racks 1301.
[0025] When conducting encoder simulation tests on different types of three-phase AC motors 7, the staff need to connect the connecting wire 8 to different types of three-phase AC motors 7 or replace the three-phase AC motor 7. The staff can turn on the servo motor 11. The output shaft of the servo motor 11 drives the guide rod 13 to rotate and drives the gear 14 to rotate. The gear 14 meshes with the rack 1301. Then, the lifting plate 9 moves upward along the guide plate 10, driving parts such as the placement table 2, the three-phase AC motor 7, and the encoder 701 to move upward together. The guide plate 10 plays a guiding role. When reaching the appropriate position, the staff can turn off the servo motor 11. The first protective shell 12 can be used to protect the servo motor 11 from being damaged. At this time, the staff can connect the connecting wire 8 to other three-phase AC motors 7 or replace the three-phase AC motor 7 that has completed the test. The staff can adjust the position of the lifting plate 9 according to the comfort of replacement or the height conducive to operation. After completion, the staff can turn on the servo motor 11 again to make the lifting plate 9 drive parts such as the placement table 2, the three-phase AC motor 7, and the encoder 701 return to the initial position.
[0026] As Figure 5 shown, it further includes an electric slide rail 4, a liquid collection tank 15, a liquid pumping pump 16, a second protective shell 17, a connecting pipe 18, and a diversion pipe 19. The front side of the placement table 2 is provided with an electric slide rail 4 by screws. A liquid collection tank 15 for storing lubricating liquid is fixedly connected to the slider on the electric slide rail 4, and an isolation plug is clamped on the liquid collection tank 15. A liquid pumping pump 16 for pumping lubricating liquid is fixedly connected to the right side of the liquid collection tank 15. A second protective shell 17 is welded outside the liquid pumping pump 16. A connecting pipe 18 penetrates and is connected inside the liquid collection tank 15, and the other side of the connecting pipe 18 is fixedly connected to the liquid pumping pump 16. A diversion pipe 19 is riveted to the liquid outlet end of the liquid pumping pump 16, and the diversion pipe 19 is in contact connection with the output shaft of the three-phase AC motor 7.
[0027] During the operation of the three-phase AC motor 7, in order to ensure smoother operation of the output shaft, when it is found that the rotation speed of the output shaft is not smooth or abnormal, the staff can add lubricating fluid to the output shaft of the three-phase AC motor 7. At this time, the staff can turn on the liquid extraction pump 16, and the liquid extraction pump 16 will extract the lubricating fluid in the liquid collection tank 15 through the connecting pipe 18 and guide it into the diversion pipe 19, and finally transport the lubricating fluid to the output shaft of the three-phase AC motor 7. After the lubricating fluid is added, turn off the motor to make the output shaft of the three-phase AC motor 7 operate normally. When adding lubricating fluid to different types of three-phase AC motors 7, the staff should first remove the diversion pipe 19 from the output shaft of the current three-phase AC motor 7. The electric slide rail 4 can be turned on to make the slider drive components such as the liquid collection tank 15, the liquid extraction pump 16, and the second protective shell 17 move left and right. The second protective shell 17 protects the liquid extraction pump 16 and prevents the liquid extraction pump 16 from being damaged during the movement. When reaching the appropriate position, turn off the electric slide rail 4, and the staff can repeat turning on and off the liquid extraction pump 16 to perform the lubricating fluid addition operation. When the lubricating fluid is used up, the staff can pull out the isolation plug from the liquid collection tank 15 to add the lubricating fluid, which is convenient for adding lubricating fluid to the three-phase AC motor 7.
[0028] As Figure 1 , Figure 2 , Figure 4 and Figure 5 shown, it further includes a glass plate 20, a protective shell 21, and a lighting lamp 22. The glass plate 20 is welded and arranged on the liquid collection tank 15. Two protective shells 21 are fixedly connected to the rear side of the support frame 1. The lighting lamp 22 is connected to the protective cover 3 by means of screws.
[0029] The staff can easily observe the storage amount of the lubricating fluid inside the liquid collection tank 15 through the glass plate 20. The function of the protective shell 21 is to isolate the gear 14, prevent foreign objects from being involved, and ensure the normal operation of the gear 14. The lighting lamp 22 ensures sufficient light inside the protective cover 3.
