Description

Technical Field

[0001] This utility model relates to the field of motor testing technology, and in particular to a motor testing device. Background Technology

[0002] In practical applications, motors typically need to operate under certain load conditions. Load testing can simulate the load conditions of a motor during actual operation, thereby evaluating whether the motor's output performance under different load conditions, such as voltage, current, speed, power, and efficiency, meets design requirements. For example, load testing can check whether the motor's output is stable at different load points and whether it is within the design range.

[0003] In existing technologies, when testing devices are connected to load structures, it is often necessary to perform complex disassembly, assembly, or replacement of load components. Moreover, when the motor output shaft is connected to the test load component, the motor position needs to be manually adjusted repeatedly. Therefore, we propose a motor testing device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a motor testing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A motor testing device includes a test chamber. An electric push rod is fixedly connected inside the test chamber. An arc-shaped plate is fixedly connected to both the bottom of the output end of the electric push rod and the inside of the test chamber. A silicone pad is fixedly connected to the outer wall of both arc-shaped plates. A bearing is fixedly connected inside the test chamber. A threaded shaft is fixedly connected to the inner ring of the bearing. A bushing is threaded onto the outer wall of the threaded shaft. A load plate is fixedly connected to one end of the bushing. A mating sleeve is fixedly connected to the outer wall of the load plate. A keyway is formed on the inner wall of the mating sleeve. A weight-increasing component is provided on the outer wall of the load plate.

[0006] Preferably, the weight-increasing component includes two threaded rods, the outer wall of the load plate is fixedly connected to one end of the two threaded rods, the outer wall of each of the two threaded rods is threaded with a locking cap, and one of the threaded rods is fitted with a counterweight plate on its outer wall. The number of counterweight plates can be increased by setting the weight-increasing component.

[0007] Preferably, the inner wall of the test chamber is provided with a sliding hole, and the inner wall of the sliding hole is slidably connected to the outer wall of the output end of the electric push rod. By setting the electric push rod to drive the arc plate and silicone plate connected thereto to move downward, the position of the motor body is fixed.

[0008] Preferably, a sound level meter is fixedly connected inside the test box, and the sound level meter records the abnormal noises generated by the motor body during operation.

[0009] Preferably, the motor body is placed on top of one of the silicone pads.

[0010] Preferably, the inner wall of the mating sleeve is slidably connected to the outer wall of the motor body output shaft.

[0011] Preferably, the outer wall of the test chamber is hinged with two sealed doors, and existing sound-absorbing cotton can be added inside the test chamber.

[0012] Compared with the prior art, the advantages of this utility model are: This solution eliminates the need for complex disassembly or replacement of load components. The load plate can be moved laterally via the threaded shaft and bushing, which in turn moves the mating sleeve to complete the docking with the motor output shaft. Furthermore, the key block on the output shaft and the keyway of the mating sleeve enable quick and precise docking. At the same time, there is no need to repeatedly manually adjust the motor position. After placing the motor on the silicone pad below, docking can be completed through the above structure.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Depend on Figures 1-3 As shown, a motor testing device is disclosed, comprising a test chamber 1. An electric push rod 2 is fixedly connected inside the test chamber 1. A sliding hole is provided on the inner wall of the test chamber 1, and the inner wall of the sliding hole is slidably connected to the outer wall of the output end of the electric push rod 2. An arc-shaped plate 3 is fixedly connected to the bottom of the output end of the electric push rod 2 and the inside of the test chamber 1. A silicone pad 4 is fixedly connected to the outer wall of both arc-shaped plates 3. A motor body 6 is placed on the top of one of the silicone pads 4. The arc-shaped plate 3 fits the outer wall of the motor body 6 more closely, which can increase the connection area with the silicone pad 4, making the compression of the motor body 6 by the silicone pad 4 more uniform, avoiding excessive local pressure that could damage the motor body 6, and improving the stability of the fixation.

[0018] The test box 1 is fixedly connected to a sound level meter 5 (6AS844). The sound level meter 5 (6AS844) can detect the sound emitted by the motor body 6 when it is running at close range and stably, providing a reliable basis for judging the motor's operating status.

[0019] The test chamber 1 is internally fixedly connected to a bearing 7, and the inner ring of the bearing 7 is fixedly connected to a threaded shaft 8. When the load rotates, the bearing 7 assists the threaded shaft 8 to rotate. A nut can be added to the outer wall of the threaded shaft 8 to tighten it to the outer wall of the bushing 9, so as to achieve the purpose of preventing loosening.

[0020] The outer wall of the threaded shaft 8 is threaded with a bushing 9. Through the threaded engagement, rotating the threaded shaft 8 can drive the bushing 9 to move laterally, thereby realizing the position adjustment of the load plate 10 and the mating sleeve 11.

[0021] One end of the bushing 9 is fixedly connected to the load plate 10, and the outer wall of the load plate 10 is fixedly connected to the mating sleeve 11. The inner wall of the mating sleeve 11 is slidably connected to the outer wall of the output shaft of the motor body 6. The mating sleeve 11 can be fitted into the outer wall of the output shaft of the motor body 6 to realize the connection between the load structure and the output shaft of the motor body 6. Its sliding connection with the output shaft facilitates quick docking and separation, simplifying the test preparation process.

[0022] The inner wall of the docking sleeve 11 is provided with a keyway 12, which can cooperate with the key block on the output shaft of the motor body 6 to ensure that the docking sleeve 11 and the output shaft of the motor body 6 are aligned. The outer wall of the test box 1 is hinged with two sealing doors 16.

[0023] The outer wall of the load plate 10 is provided with a weight-increasing component, which includes two threaded rods 13. The outer wall of the load plate 10 is fixedly connected to one end of the two threaded rods 13. The outer wall of each of the two threaded rods 13 is threaded with a locking cap 15, and a counterweight plate 14 is fitted on the outer wall of one of the threaded rods 13.

[0024] Working principle: During use, open the sealing door 16, place the motor body 6 on the lower silicone pad 4, and rotate the threaded shaft 8 to drive the bushing 9 and load plate 10 to move laterally. The movement of the load plate 10 drives the docking sleeve 11 to move, so that the docking sleeve 11 fits onto the outer wall of the output shaft of the motor body 6, and the key block on the output shaft (to ensure precise alignment and firm connection between the shaft and the connecting parts) slides into the keyway 12. The electric push rod 2 drives the arc plate 3 and silicone pad 4 connected to it to move downward, so that the upper silicone pad 4 is pressed against the outer wall of the motor body 6 to fix its position. The operation of the motor body 6 drives the docking sleeve 11, load plate 10 and bushing 9 to rotate through the key block on the output shaft and the keyway 12. The rotation of the load plate 10 drives the two threaded rods 13 and the counterweight plate 14 to rotate, realizing the load test. The locking cap 15 can be rotated in advance to increase the number of counterweight plates 14 through the threaded rods 13. During the load test, the sound emitted by the motor body 6 is recorded by the sound level meter 5.

[0025] It should be noted that, in actual use, an existing PLC controller can be added. The PLC controller is electrically connected to the electric push rod 2, the motor body 6, and the sound level meter 5 to facilitate the control of the overall operation.
