Description

Technical Field

[0001] This utility model belongs to the field of circuit fault detection technology, specifically relating to a workbench for detecting hardware circuit faults in asynchronous motors. Background Technology

[0002] An asynchronous motor hardware circuit fault detection workbench is a device specifically designed for testing and diagnosing hardware circuit faults in asynchronous motors. Its working principle is based on the operating principles of motors and circuit analysis techniques. By changing parameters such as power supply frequency, voltage, and load, the workbench can simulate the motor's operating state under different conditions. Simultaneously, sensors measure various motor parameters, which are then processed and analyzed by the control system to derive the motor's performance parameters and fault information.

[0003] The asynchronous motor hardware circuit fault detection workbench is widely used in motor manufacturing, repair, scientific research, and teaching. In motor manufacturing, it can be used for performance testing and quality evaluation; in repair, it can be used for fault diagnosis and troubleshooting; and in scientific research and teaching, it can be used for teaching and experimenting with motor principles.

[0004] Existing workbenches for detecting faults in asynchronous motor hardware circuits often suffer from inflexible designs, particularly the partitions used for placing parts, which are typically designed in a fixed style. While this fixed partition layout may provide some stability and support in certain situations, it reveals numerous inconveniences in practical use. Because the position and spacing of the partitions cannot be adjusted according to actual needs, operators often find it difficult to find suitable placement space when testing asynchronous motor hardware circuits of different specifications or types. This results in disorganized parts placement, affecting work efficiency and potentially increasing the risk of misoperation or part damage. Furthermore, the fixed partition design limits the workbench's versatility and adaptability, making it difficult to meet the personalized needs of different users or different testing tasks. Utility Model Content

[0005] The purpose of this utility model is to provide a workbench for detecting hardware circuit faults in asynchronous motors. It aims to solve the problem that existing workbench designs for detecting hardware circuit faults in asynchronous motors often lack flexibility, especially the partitions used to place parts, which are usually designed in a fixed style. This fixed partition design also limits the versatility and adaptability of the workbench, making it difficult to meet the personalized needs of different users or different testing tasks.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a workbench for detecting hardware circuit faults in asynchronous motors, comprising a workbench surface, a support, a partition, and a socket plate. The support is mounted on the upper surface of the workbench surface, a partition is provided on the inner wall of the support, and a socket plate is connected to the inner wall of the support. A first rotating shaft is connected to the end of the partition, a bearing ring is connected between the first rotating shaft and the support, a housing is connected to the side surface of the partition, a rod passes through the interior of the housing, a limit block is connected to the surface of the rod, a spring strip is connected between the limit block and the inner wall of the housing, a first fixing hole is connected to the side surface of the support, and a second fixing hole is connected to the side surface of the support.

[0007] As a preferred workbench for detecting hardware circuit faults in asynchronous motors according to this utility model, the first rotating shaft and the bearing ring are symmetrically arranged at both ends of the partition, and the first rotating shaft forms a rotating structure with the support through the bearing ring.

[0008] As a preferred workbench for detecting faults in the hardware circuit of the asynchronous motor of this utility model, the insertion rod and the limiting block are an integral structure, and the limiting block and the spring strip form an elastic telescopic structure.

[0009] As a preferred embodiment of the workbench for detecting hardware circuit faults in asynchronous motors according to this utility model, a first bearing seat is mounted on the surface of the socket plate, a second rotating shaft is connected through the interior of the first bearing seat, a square support arm is connected to the side surface of the second rotating shaft, an extension square tube is sleeved on the surface of the square support arm, an illumination lamp is mounted at the end of the extension square tube, a driven bevel gear is connected to the surface of the second rotating shaft, a drive motor is mounted on the surface of the workbench, an active bevel gear is connected to the output end of the drive motor, a second bearing seat is mounted on the side surface of the square support arm, a threaded rod is connected through the interior of the second bearing seat, and a threaded tube is connected to the side surface of the extension square tube sleeved with the threaded rod.

[0010] As a preferred workbench for detecting hardware circuit faults in asynchronous motors according to this utility model, the second rotating shaft forms a rotating structure between the first bearing seat and the socket plate, the second rotating shaft and the square support arm are an integral structure, and the square support arm and the extended square tube are slidably connected.

[0011] As a preferred workbench for detecting faults in the hardware circuit of the asynchronous motor of this utility model, the driven bevel gear and the driving bevel gear form a meshing structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, when the insert rod is subjected to tension, the spring strip can be compressed by the limiting block. When the insert rod moves to the outside of the first fixing hole, it pulls the partition to rotate. After the partition rotates 90°, the insert rod is released. At this time, the spring strip drives the insert rod to reset through the limiting block. After the insert rod resets, it can enter the interior of the second fixing hole. In this way, the position of the partition can be fixed by inserting the insert rod into the second fixing hole, so that the partition can be folded up. The folding and unfolding of the two partitions can be adjusted according to the storage needs of the partition and the height of the storage components, increasing the convenience and practicality of the workbench.

[0015] In this invention, the drive motor can rotate the active bevel gear when it is running. The rotation of the active bevel gear can drive the second rotating shaft to rotate through the driven bevel gear. The rotation of the first bearing seat can drive the illumination lamp to rotate through the square support arm and the extended square tube. The rotation of the threaded rod can drive the threaded tube to move laterally. The lateral movement of the threaded tube can drive the illumination lamp to move laterally through the extended square tube. In this way, the illumination position of the illumination lamp can be adjusted, which can facilitate lighting when the asynchronous motor is used for hardware circuit fault detection.

A first rotating shaft 5 is connected to the end of the partition 3, and a bearing ring 6 is connected between the first rotating shaft 5 and the support 2. A housing 7 is connected to the side surface of the partition 3, and a rod 8 passes through the inside of the housing 7. A limit block 9 is connected to the surface of the rod 8, and a spring strip 10 is connected between the limit block 9 and the inner wall of the housing 7. A first fixing hole 11 is connected to the side surface of the support 2, and a second fixing hole 12 is connected to the side surface of the support 2.

[0026] When performing hardware circuit fault detection on an asynchronous motor, first install the testing equipment on the surface of the workbench 1, then disassemble the asynchronous motor and perform hardware circuit fault detection using the testing equipment.

[0027] Preferably, the first rotating shaft 5 and the bearing ring 6 are symmetrically arranged at both ends of the partition plate 3, and the first rotating shaft 5 forms a rotating structure with the support 2 through the bearing ring 6.

[0028] In practical use, when the partition 3 is subjected to a force, it can drive the first rotating shaft 5 to rotate inside the bearing ring 6, thus adjusting the angle of the partition 3.

[0029] Preferably, the insertion rod 8 and the limiting block 9 are an integral structure, and the limiting block 9 and the spring strip 10 form an elastic telescopic structure.

[0030] In actual use, when the insertion rod 8 is subjected to tension, it can cause the limiting block 9 to compress the spring strip 10. After the force disappears, the elasticity of the spring strip 10 can squeeze the limiting block 9 and the insertion rod 8 to reset.

[0031] Preferably: A first bearing seat 13 is mounted on the surface of the socket plate 4, a second rotating shaft 14 is connected through the interior of the first bearing seat 13, a square support arm 15 is connected to the side surface of the second rotating shaft 14, an extension square tube 16 is sleeved on the surface of the square support arm 15, an illumination lamp 17 is mounted at the end of the extension square tube 16, a driven bevel gear 18 is connected to the surface of the second rotating shaft 14, a drive motor 19 is mounted on the surface of the worktable 1, an active bevel gear 20 is connected to the output end of the drive motor 19, a second bearing seat 21 is mounted on the side surface of the square support arm 15, a threaded rod 22 is connected through the interior of the second bearing seat 21, and a threaded tube 23 is connected to the side surface of the extension square tube 16 sleeved with the threaded rod 22.

[0032] Preferably, the second rotating shaft 14 forms a rotating structure between the first bearing seat 13 and the socket plate 4, the second rotating shaft 14 and the square support arm 15 are an integral structure, and the square support arm 15 and the extended square tube 16 are slidably connected.

[0033] Preferably, the driven bevel gear 18 and the driving bevel gear 20 form a meshing structure.

[0034] In practical use, when the drive motor 19 drives the active bevel gear 20 to rotate, it can drive the driven bevel gear 18 to rotate through the meshing structure, thereby realizing transmission.

[0035] Preferably, the threaded rod 22 forms a rotating structure with the square support arm 15 through the second bearing seat 21, and the threaded rod 22 and the threaded tube 23 are connected by threads.

[0036] In practical use, when the threaded rod 22 rotates, it can drive the threaded tube 23 to move laterally through the threaded connection. When the threaded tube 23 moves, it can drive the extended square tube 16 to slide on the surface of the square support arm 15, thereby adjusting the position of the illumination lamp 17.

[0037] Working principle: When using the workbench for detecting hardware circuit faults of this asynchronous motor, when the partition 3 is not needed, the insertion rod 8 can be pulled first. When the insertion rod 8 is under tension, it can compress the spring strip 10 through the limit block 9. When the insertion rod 8 moves to the outside of the first fixing hole 11, the partition 3 can be pulled to drive the first rotating shaft 5 to rotate inside the bearing ring 6. When the partition 3 rotates 90°, the insertion rod 8 is released. At this time, the spring strip 10 squeezes the limit block 9 through its own elasticity. The limit block 9 being squeezed can drive the insertion rod 8 to reset. After the insertion rod 8 resets, it can enter the inside of the second fixing hole 12. In this way, the position of the partition 3 can be fixed by the insertion of the insertion rod 8 into the second fixing hole 12, so that the partition 3 can be retracted.

[0038] During the testing process, the drive motor 19 can be operated. When the drive motor 19 is running, it can drive the active bevel gear 20 to rotate. The rotation of the active bevel gear 20 can drive the second rotating shaft 14 to rotate inside the first bearing seat 13 through the driven bevel gear 18. The rotation of the first bearing seat 13 can drive the illumination lamp 17 to rotate through the square support arm 15 and the extended square tube 16. Then, the threaded rod 22 can be rotated. The rotation of the threaded rod 22 can drive the threaded tube 23 to move laterally. The lateral movement of the threaded tube 23 can drive the illumination lamp 17 to move laterally through the extended square tube 16. In this way, the illumination position of the illumination lamp 17 can be adjusted.

[0039] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
