Description

Technical Field

[0001] This utility model belongs to the field of motor impeller processing technology, and in particular relates to a motor impeller disassembly and clamping mechanism. Background Technology

[0002] Motor impellers are crucial components in motor systems, widely used in various types of motors such as centrifugal fans, compressors, and pumps. The performance of the impeller directly affects the motor's efficiency, noise, and vibration levels; therefore, disassembling and assembling motor impellers is a common and important operation during production, maintenance, and repair. However, traditional methods of disassembling and assembling motor impellers have many problems, affecting work efficiency and operational safety.

[0003] Traditional motor impeller disassembly and assembly mainly rely on manual operation or simple tools such as wrenches and hammers. This method has the following problems: During disassembly, due to the lack of precise control, scratches can easily be caused on the impeller surface, or even deformation of the impeller; if the impeller is not securely fixed during operation, it may accidentally slip or fall off, damaging not only the impeller but also surrounding components; in addition, traditional disassembly methods cannot accurately fix the impeller position, requiring repeated adjustments during disassembly, making the entire disassembly process time-consuming and seriously affecting the efficiency of personnel.

[0004] To address these issues, we provide a motor impeller assembly and disassembly clamping mechanism. Utility Model Content

[0005] The purpose of this utility model is to provide a clamping mechanism for disassembling and assembling a motor impeller. Through the action of the clamping plate, the device can flexibly adjust the angle, making it easy to accurately insert into the gap and clamp the impeller, reducing the shaking of the impeller during disassembly. In addition, a reinforcing strip made of rubber material is fixed on one side of the clamping plate. When the impeller is pried up, the rubber material can prevent the clamping plate from making direct hard contact with the impeller surface, preventing scratches or deformation of the impeller surface, protecting the integrity and performance of the impeller. This solves the problem that the existing traditional disassembly method cannot accurately fix the position of the impeller, which leads to repeated adjustments during the disassembly process, making the entire disassembly process time-consuming and seriously affecting the work efficiency of personnel.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a disassembly and clamping mechanism for a motor impeller, including a base, a bracket fixed on the upper surface of the base, and a crossbeam fixed on the top of the bracket;

[0007] A threaded tube is fixed to one side of the bracket, and a threaded rod is threadedly connected inside the threaded tube.

[0008] A transmission rod is fixed to one end of the threaded rod, and a first bearing is fixed to one end of the transmission rod.

[0009] An adjusting plate is fixed to the outer ring of the first bearing, a second bearing is fixed to the surface of the adjusting plate, and an adjusting rod is fixed to the inner ring of the second bearing.

[0010] One end of the adjusting rod is fixed to a main moving rod, and the end of the main moving rod away from the second bearing is rotatably connected to a secondary moving rod.

[0011] A push rod is rotatably connected to one end of the movable rod, and a disassembly plate is fixed to the bottom of the push rod;

[0012] The disassembly plate has a transmission groove on one side, and a positioning rod is fixed inside the transmission groove;

[0013] The outer ring of the positioning rod is rotatably connected to a locking plate.

[0014] The present invention is further configured such that: a through hole is opened on one side of the card plate, and the positioning rod passes through the through hole.

[0015] The present invention is further configured such that a reinforcing strip is fixed on one side of the card plate, and the reinforcing strip is made of rubber material.

[0016] The present invention is further configured such that: a limiting plate is fixed on one side of the adjusting plate, and the push rod passes through the limiting plate;

[0017] The limiting plate is slidably connected to the push rod.

[0018] The present invention is further configured such that: a placement groove is fixed on the upper surface of the base, and a storage box is fixed on one side of the bracket.

[0019] The present invention is further configured such that: a limit groove is opened at the bottom of the crossbeam, and a limit block is fixed on the upper surface of the adjustment plate;

[0020] The limiting block has a "T" shaped structure and is slidably connected to the inner wall of the limiting groove.

[0021] The present invention is further configured such that: a plurality of mounting holes are opened on one side of the adjusting plate, and a handle is fixed to the end of the adjusting rod away from the main moving rod;

[0023] The lever passes through the handle, and one end of the lever is inserted into the mounting hole.

[0024] This utility model has the following beneficial effects:

[0025] 1. This utility model utilizes the clamping plate to allow for flexible angle adjustment, facilitating accurate insertion into the gap and clamping of the impeller, reducing impeller wobbling during disassembly. Furthermore, a reinforcing strip made of rubber is fixed to one side of the clamping plate. When the impeller is pried up, the rubber material prevents the clamping plate from making direct hard contact with the impeller surface, preventing scratches or deformation on the impeller surface and protecting the integrity and performance of the impeller.

[0026] 2. This utility model utilizes the action of a locking rod, which is connected to the handle via a tension spring. When the adjusting rod lowers the disassembly plate to a suitable height, the locking rod is pulled and engages with the mounting hole of the adjusting plate. This fixes the position of the adjusting rod and prevents the locking plate from shifting due to mechanism shaking during disassembly, ensuring the accuracy of clamping and disassembly actions.

Specific Implementation Example 1

[0039] Please see Figure 1-5 This utility model is a disassembly and clamping mechanism for a motor impeller, including a base 1, a bracket 2 fixed on the upper surface of the base 1, a crossbeam 3 fixed on the top of the bracket 2; a threaded tube 4 fixed on one side of the bracket 2, a threaded rod 5 threadedly connected inside the threaded tube 4; a transmission rod 6 fixed at one end of the threaded rod 5, a first bearing 7 fixed at one end of the transmission rod 6; an adjusting plate 8 fixed on the outer ring of the first bearing 7, a second bearing 9 fixed on the surface of the adjusting plate 8, an adjusting rod 10 fixed on the inner ring of the second bearing 9; a main moving rod 11 fixed at one end of the adjusting rod 10, a secondary moving rod 12 rotatably connected to the end of the main moving rod 11 away from the second bearing 9; a push rod 13 rotatably connected to one end of the secondary moving rod 12, a disassembly plate 14 fixed at the bottom of the push rod 13; a transmission groove 15 opened on one side of the disassembly plate 14, a positioning rod 16 fixed inside the transmission groove 15; a clamping plate 17 rotatably connected to the outer ring of the positioning rod 16.

[0040] Specifically, a through hole 18 is opened on one side of the card plate 17, and the positioning rod 16 passes through the through hole 18.

[0041] Furthermore, a reinforcing strip 19 is fixed to one side of the card plate 17, and the reinforcing strip 19 is made of rubber material.

[0042] The operation process of this embodiment is as follows: The motor is placed vertically in the placement slot 21 of the base 1. The shape of the placement slot 21 is used to position and fix the bottom of the motor, ensuring stability during disassembly and assembly. Tools or disassembled parts can be placed in the storage box 22 on one side of the bracket 2 for easy organization and retrieval. Using a screwdriver or other tools, the screws on the motor cover are removed, and the motor cover is opened to expose the impeller for subsequent operations. Then, the threaded rod 5 is rotated, driving the transmission rod 6 to move via the threaded transmission, thereby moving the adjusting plate 8 horizontally. This aligns the disassembly plate 14 with the gap between the impeller and the inner wall of the motor housing. During this process, the T-shaped limiting block 24 on the adjusting plate 8 is slidably connected to the limiting groove 23 at the bottom of the crossbeam 3, ensuring the stability of the horizontal movement. The disassembly plate 14 is pushed, causing the clamping plate 17 on one side to insert into the gap between the impeller and the motor housing. The free end of the clamping plate 17 is rotated, using the positioning rod 16 as a support... The clamping plate 17, with one end of the rubber reinforcing strip 19 fixed to it, rests against the edge of the impeller. Since the reinforcing strip 19 is made of rubber, it avoids direct contact with the impeller surface, preventing scratches, while providing sufficient friction and support. By continuously rotating the clamping plate 17, the impeller is slowly pried up using the lever principle, separating it from the motor shaft and completing the disassembly. The clamping plate 17 can be inserted into the gap between the impeller and the inner wall of the motor housing. By rotating the clamping plate 17, using the positioning rod 16 as a fulcrum, the impeller is pried up using the lever principle, separating it from the motor shaft, thus completing the disassembly operation. This device can be flexibly adjusted in angle, making it easy to accurately insert into the gap and clamp the impeller, reducing the impeller's shaking during disassembly. Furthermore, the reinforcing strip 19 made of rubber is fixed on one side of the clamping plate 17. When prying up the impeller, the rubber material prevents the clamping plate 17 from directly contacting the impeller surface, preventing scratches or deformation on the impeller surface and protecting the integrity and performance of the impeller. Specific Implementation Example 2

[0044] Please see Figure 4 Based on the first specific embodiment, a limiting plate 20 is fixed on one side of the adjusting plate 8, and the push rod 13 passes through the limiting plate 20; the limiting plate 20 and the push rod 13 are slidably connected; a placement groove 21 is fixed on the upper surface of the base 1, and a storage box 22 is fixed on one side of the bracket 2.

[0045] Specifically, a limiting groove 23 is opened at the bottom of the crossbeam 3, and a limiting block 24 is fixed on the upper surface of the adjusting plate 8; the limiting block 24 has a "T" shaped structure and is slidably connected to the inner wall of the limiting groove 23.

[0046] Furthermore, several mounting holes 25 are opened on one side of the adjusting plate 8, and a handle 26 is fixed to the end of the adjusting rod 10 away from the main moving rod 11; a tension spring 27 is fixed to one side of the handle 26, a movable plate 28 is fixed to one end of the tension spring 27, and a locking rod 29 is fixed to one side of the movable plate 28; the locking rod 29 passes through the handle 26, and one end of the locking rod 29 is inserted into the mounting hole 25.

[0047] The operation process of this embodiment is as follows: When the height of the disassembly plate 14 is insufficient, the handle 26 can be held and the adjusting rod 10 can be rotated. The adjusting rod 10 drives the main moving rod 11 and the driven moving rod 12 to move, thereby pushing the push rod 13 to descend vertically along the guide hole of the limiting plate 20, so that the disassembly plate 14 descends to the gap between the impeller and the motor housing. At this time, the clamping plate 17 needs to be aligned with the gap. After adjusting to a suitable height, the clamping rod 29 on the handle 26 is pulled to insert the clamping rod 29 into the mounting hole 25 on the adjusting plate 8. After releasing the hand, the clamping rod 29 is reset by the tension spring 27, fixing the position of the adjusting rod 10 and preventing the mechanism from shaking during disassembly. The clamping rod 29 is connected to the handle 26 by the tension spring 27. When the adjusting rod 10 drives the disassembly plate 14 to a suitable height, the clamping rod 29 is pulled and inserted into the mounting hole 25 of the adjusting plate 8, which can fix the position of the adjusting rod 10 and prevent the clamping plate 17 from shifting due to the shaking of the mechanism during disassembly, ensuring the accuracy of the clamping and disassembly actions.
