Description

Technical Field

[0001] This utility model relates to the technical field of motor disassembly and assembly equipment, specifically to a motor stator and rotor disassembly equipment. Background Technology

[0002] As a core component of a ship's propulsion system, the reliability of the electric motor directly affects the ship's navigation safety and operational efficiency. To ensure stable operation, periodic disassembly and maintenance are necessary.

[0003] Publication number CN218733748U discloses a special tool for disassembling and assembling motors. When in operation, the motor with the end cover removed is placed on the upper side of the feeding hole, and the outer wall of the stator is clamped by two clamping plates. Then, the rotor is squeezed by the downward pressing block, so that the rotor is separated from the stator and enters the storage groove through the feeding hole, thereby realizing the disassembly of the stator and the rotor.

[0004] However, since there is usually a certain gap between the rotor and the stator to ensure that the rotor can rotate relative to the stator, the rotor is not fixed when the rotor is pressed down by the pressure block in the above patent. This makes it easy for the rotor to tilt or even shift relative to the stator during the separation process, which can lead to damage to the rotor or stator. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a motor stator and rotor disassembly device to solve the technical problem that in the prior art, when the rotor is pressed down by the pressure block, the rotor is not fixed, which easily causes the rotor to tilt or even shift relative to the stator during the separation process, thus leading to damage to the rotor or stator.

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0038] To address the technical problem that the rotor is not fixed when pressed down by the pressure block, which can easily cause the rotor to tilt or even shift relative to the stator during the separation process, thus leading to damage to the rotor or stator, this utility model provides a motor rotor and stator disassembly device. Since the two shaft ends of the rotor are fixed by the pin and the rotor connection part respectively, the rotor is axially fixed and will not tilt or shift relative to the stator, effectively avoiding damage to the rotor and stator during disassembly and ensuring the quality of the motor.

[0039] Please see Figures 1 to 3 , Figures 1 to 3 This is a schematic diagram of the structure of a motor stator and rotor disassembly device according to an embodiment of the present invention. The motor stator and rotor disassembly device includes an installation part 1, a stator connection part 2, a rotor connection part 3, and a push pin 4. The stator connection part 2 is disposed on the installation part 1 and is used to detachably connect the stator. The rotor connection part 3 is movably disposed on the installation part 1 and is used to detachably connect the shaft end of the rotor. The push pin 4 is disposed on the installation part 1 and is located on the side of the stator connection part 2 away from the rotor connection part 3. It is used to press against the shaft end of the rotor away from the rotor connection part 3 and can move synchronously with the rotor connection part 3 relative to the stator connection part 2. Its movement direction is parallel to the arrangement direction of the push pin 4 and the rotor connection part 3. Specifically, its movement direction is parallel to the axial direction of the rotor.

[0040] In the motor stator and rotor disassembly device provided by this utility model, the motor with the end cover removed is first placed at the stator connection part 2, and the stator of the motor is fixed by the stator connection part 2. Then, the rotor connection part 3 and the ejector pin 4 are respectively connected to the two shaft ends of the rotor. Then, the ejector pin 4 and the rotor connection part 3 are driven to move synchronously relative to the stator connection part 2, while the stator moves towards the ejector pin 4. In this way, during the synchronous movement of the ejector pin 4 and the rotor connection part 3 relative to the stator connection part 2, the stator can move to the position corresponding to the ejector pin 4, realizing the disassembly of the stator and rotor, and the ejector pin 4 will not interfere with the stator when it is inserted into the stator. At the same time, since the two shaft ends of the rotor are respectively fixed by the ejector pin 4 and the rotor connection part 3, the rotor is axially fixed and will not tilt or shift relative to the stator, effectively avoiding damage to the rotor and stator during disassembly and ensuring the quality of the motor.

[0041] It should be noted that the mounting part 1 can be configured as a frame, a disassembly base, a disassembly box, or other forms. Specifically, in this solution, the mounting part 1 is configured as a frame. Furthermore, it should be understood that the stator connecting part 2 can be movable relative to the mounting part 1, and the rotor connecting part 3 and the ejector pin 4 can be fixed to the mounting part 1; alternatively, the rotor connecting part 3 and the ejector pin 4 can be movable relative to the mounting part 1, and the stator connecting part 2 can be fixed to the mounting part 1; other forms are also possible.

[0042] In another embodiment, the stator connection 2, the rotor connection 3, and the ejector pin 4 can all move relative to the mounting part 1 along the arrangement direction of the ejector pin 4 and the rotor connection 3.

[0043] In this embodiment, all three components are configured to be movable relative to the mounting part 1, thereby allowing for flexible adjustment of the distance between them. Furthermore, the rotor connecting part 3 and the ejector pin 4 can be driven to move synchronously relative to the stator connecting part 2 as needed, thus improving flexibility and practicality.

[0044] In one embodiment, the motor stator and rotor disassembly device further includes a drive unit 5, which is located on the mounting part 1 and connected to the stator connection part 2, the rotor connection part 3 and the ejector pin 4. The drive unit 5 can drive the stator connection part 2, the rotor connection part 3 and the ejector pin 4 to move independently relative to the mounting part 1 along the arrangement direction of the ejector pin 4 and the rotor connection part 3.

[0045] In this embodiment, the stator connecting part 2, rotor connecting part 3, and ejector pin 4 are driven to move independently by the driving part 5, so that the three movements do not interfere with each other, thus improving stability. Moreover, when disassembling the motor, the rotor connecting part 3 and ejector pin 4 can be driven to be fixed opposite to the mounting part 1, and the stator connecting part 2 can be driven to move the stator toward the side of ejector pin 4, thereby realizing the disassembly of the stator and rotor.

[0046] It should be noted that the drive unit 5 can be configured as three linear motors, three hydraulic rods or three electric actuators, respectively assembled on the stator connection part 2, the rotor connection part 3 and the ejector pin 4, so as to realize the independent movement of the three.

[0047] In one embodiment, please refer to Figures 3 to 5 The ejector pin 4 includes an ejector pin seat 41 and an ejector pin body 42. The ejector pin seat 41 is located on the mounting part 1 and can move synchronously with the rotor connecting part 3 relative to the stator connecting part 2. Its direction of movement is parallel to the arrangement direction of the ejector pin seat 41 and the rotor connecting part 3. The ejector pin body 42 is located on the ejector pin seat 41 and is used to press against the shaft end of the rotor away from the rotor connecting part 3. It can move relative to the ejector pin seat 41, and its direction of movement is parallel to the direction of movement of the ejector pin seat 41 relative to the stator connecting part 2. It can also maintain the position after movement relative to the ejector pin seat 41.

[0048] In this embodiment, the ejector seat 41 can drive the ejector body 42 to approach and move away from the stator connection part 2. At the same time, the ejector body 42 can also approach and move away from the stator connection part 2 relative to the ejector seat 41, and maintain the adjusted position relative to the ejector seat 41, making the pressure adjustment of the rotor shaft end more flexible.

[0049] It should be noted that the movement of the ejector body 42 relative to the ejector seat 41 can be achieved by a linear motor, hydraulic rod, electric actuator or other means.

[0050] In another embodiment, the ejector seat 41 extends along the direction of movement relative to the stator connection 2 and has an adjustment channel 41a. The ejector body 42 is disposed in the adjustment channel 41a and has an adjustment screw hole 42a along its direction of movement. The motor stator and rotor disassembly equipment also includes an adjustment screw 6, which is rotatably mounted on the ejector seat 41 and screwed into the adjustment screw hole 42a. When rotated, the adjustment screw 6 can drive the ejector body 42 to move along the extension direction of the adjustment channel 41a.

[0051] In this embodiment, the ejector body 42 is driven to move closer to and further away from the shaft end of the rotor by rotating the drive screw, so that the position adjustment of the ejector body 42 is more precise and to prevent back-and-forth movement and displacement during the separation operation, thus providing basic positioning support for precise disassembly.

[0052] In one embodiment, a limiting block 411 is provided on one of the inner walls of the ejector body 42 and the adjustment channel 41a, and a limiting groove 42b is provided on the other for the limiting block 411 to slide. The limiting groove 42b extends along the activity direction of the ejector body 42.

[0053] In this embodiment, a limiting groove 42b is provided on the limiting block 411 as described above to guide the ejector body 42 to move in the direction of approaching and moving away from the stator connection portion 2, thereby preventing the ejector body 42 from rotating. Specifically, in this solution, the limiting groove 42b is located on the outer side of the ejector body 42, and the limiting block 411 is located on the inner wall of the adjustment channel 41a.

[0054] In one embodiment, the ejector pin 4 includes an ejector pin sleeve 43 and a plurality of support rods 44. The ejector pin sleeve 43 is installed on the mounting part 1 and can move synchronously with the rotor connecting part 3 relative to the stator connecting part 2. Its movement direction is parallel to the arrangement direction of the ejector pin 4 and the rotor connecting part 3. The plurality of support rods 44 have different lengths and can be selectively assembled on the ejector pin sleeve 43. Each support rod 44 and the ejector pin sleeve 43 are detachably connected.

[0055] In this embodiment, various sizes of support rods 44 are provided to accommodate the assembly requirements of different motor models, thereby improving practicality. It should be noted that the detachable connection between the support rod 44 and the ejector sleeve 43 can be achieved through threaded connection, snap-fit ​​connection, or other methods.

[0056] In another embodiment, the ejector sleeve 43 is provided with an insertion hole 43a along the direction close to the stator connection portion 2, and the inner diameter of the insertion hole 43a is gradually widened along the direction close to the stator connection portion 2. Correspondingly, the support rod 44 includes a tapered section and a support section connected together. The tapered section is adapted to the inner diameter of the insertion hole 43a, and the support section is used to press down the shaft end of the rotor to ensure the overall accuracy after installing the extended support rod 44, and to enable quick and convenient assembly and disassembly.

[0057] It should be noted that the stator connection part 2 can be configured as a gripper, a robotic arm, or other forms. The rotor connection part 3 can be configured as another ejector pin 4, a gripper, or other forms.

[0058] In another embodiment, please refer to Figure 6 and Figure 7 The stator connection part 2 includes a fixing seat 21 and a fixing bolt. The fixing seat 21 is located in the mounting part 1 and has a fixing screw hole 212a. The fixing bolt is used to pass through the foot hole of the stator and is threaded to the fixing seat 21 via the fixing screw hole 212a. The rotor connection part 3 includes a chuck 31. The chuck 31 is located in the mounting part 1 and is used to clamp the shaft end of the rotor. It can move synchronously with the ejector pin 4 relative to the fixing seat 21, and its movement direction is parallel to the arrangement direction of the ejector pin 4 and the chuck 31.

[0059] In this embodiment, the stator's base is detachably mounted to the fixed base 21 using fixing bolts. The rotor's shaft end is clamped by the chuck 31, resulting in a stable and reliable structure. It should be noted that the specific structure and principle of the chuck 31 are existing technologies and will not be described in detail here.

[0060] In one embodiment, the fixed base 21 includes a base 211, a movable base 212, and a movable adjustment member 213. The base 211 is disposed on the mounting part 1, the movable base 212 is movably disposed on the base 211, and its movement direction intersects the arrangement direction of the ejector pin 4 and the chuck 31. The movable adjustment member 213 is disposed on the base 211 and connected to the movable base 212 for driving the movable base 212 to move. A fixing screw hole 212a is formed in the movable base 212.

[0061] In this embodiment, the height of the movable seat 212 can be flexibly adjusted to ensure that the stator connection part 2 and the rotor connection part 3 are on the same axis, thereby improving the assembly and disassembly accuracy. It should be noted that this solution also includes a telescopic laser detection mechanism 9, which scans the inner wall contour of the stator non-contactly with a laser beam, automatically generates the position of the central axis through spatial coordinate calculation, and displays the position offset in the X, Y, and Z directions on the operation screen in real time, intuitively presenting the spatial deviation state between the stator and the reference axis.

[0062] Specifically, the telescopic laser detection mechanism 9 has two sets, corresponding to the chuck 31 and the ejector pin 4 respectively. Its specific structure and principle are existing technologies and will not be described in detail here.

[0063] In one embodiment, please refer to Figure 8The installation unit 1 has a stator station 11, a rotor station 12, and a disassembly station 13. The stator station 11 and the rotor station 12 are located on the same side of the disassembly station 13. The stator connection part 2 is located at the disassembly station 13 and is adjacent to the stator station 11. The rotor connection part 3 is located at the disassembly station 13 and is adjacent to the rotor station 12. The motor stator and rotor disassembly equipment also includes a first material transfer mechanism 7 and a second material transfer mechanism 8. The first material transfer mechanism 7 is located between the stator station 11 and the disassembly station 13 and is used to move materials between the stator station 11 and the disassembly station 13. The second material transfer mechanism 8 is located between the rotor station 12 and the disassembly station 13 and is used to move materials between the rotor station 12 and the disassembly station 13.

[0064] In this embodiment, the motor to be disassembled can be placed on the stator station 11, and the motor to be disassembled can be moved to the stator connection part 2 of the disassembly station 13 by the first material transfer mechanism 7. After the motor is disassembled, the stator can be moved to the stator station 11 by the first material transfer mechanism 7, and the rotor can be moved to the rotor station 12 by the second material transfer mechanism 8, thereby improving the efficiency of loading and unloading.

[0065] It should be noted that the first material transfer mechanism 7 and the second material transfer mechanism 8 can be configured as a conveyor belt, a conveyor roller, or a transfer robotic arm. Specifically, in this solution, both material transfer mechanisms are configured as conveyor rollers.

[0066] Furthermore, in this design, a rotor transition platform 20 and a lifting adjustment component are provided between the rotor station 12 and the disassembly station 13. The rotor transition platform 20 is jacking-up and jacking mounted on the mounting section 1, and a material transfer mechanism is installed on it. This material transfer mechanism can move closer to and further away from the disassembly station 13 to avoid the disassembly station 13 and to transfer materials to the disassembly station 13. The lifting adjustment component is installed on the mounting section 1 and connected to the rotor transition platform 20 to drive the rotor transition platform 20 to move up and down. It can be configured as a lead screw nut, a hydraulic rod, or a linear motor.

[0067] In one embodiment, please refer to Figure 8 and Figure 9 The motor stator and rotor disassembly equipment also includes two clamping plates 10 and a clamping drive. The two clamping plates 10 are installed on the mounting part 1 and located above the stator station 11, on opposite sides of the stator station 11, and can move closer and further away from each other to clamp the two ends of the motor in the axial direction. The clamping plates 10 are provided with clearance grooves to avoid the rotor. The clamping drive is installed on the mounting part 1 and connected to the two clamping plates 10 to drive the two clamping plates 10 to move closer and further away from each other.

[0068] In this embodiment, two clamping plates 10 clamp the two ends of the motor along its axial direction, specifically clamping the stator core. This automatically detects and corrects minor deformations caused by transportation or disassembly, restoring the stator to its standard roundness and ensuring precise alignment with the rotor. When the motor is disassembled and removed from the production line, the clamping force of the two clamping plates 10 is released, and the side plates synchronously return to a safe distance, preventing the stator from rebounding and colliding, thus ensuring the safety of equipment and personnel. It should be noted that the clamping drive can be configured as two hydraulic cylinders, an electric actuator, or a linear motor.

[0069] To better understand this utility model, the following is combined with... Figures 1 to 9 The technical solution of this utility model is described in detail below:

[0070] The disassembly process of the motor in this solution is as follows:

[0071] Step 1: Pre-processing and positioning of the stator and rotor assembly, including hoisting and transfer, and attitude correction.

[0072] 1. Lifting and Transfer: After removing the end cover bearings, the stator and rotor assembly is lifted onto the pallet at stator station 11, and the pallet is transferred between the two clamping plates 10 by the conveyor rollers.

[0073] 2. Attitude correction: Drive the clamping plate 10 to clamp the stator and rotor assembly. When the clamping force reaches the set threshold, usually greater than or equal to 5kN, it will automatically correct the deviation. After the correction is completed, the clamping plate 10 will reset and release.

[0074] Step 2: Stator precision positioning, including height compensation and three-dimensional precision calibration.

[0075] 1. Lifting compensation: The conveyor roller transfers the stator and rotor assembly to the movable frame, and the stator is assembled onto the movable seat 212 by fixing bolts. The deviation value between the stator and the central axis of the equipment is input, and the servo lifting device lifts and positions itself according to the compensation value. The minimum compensation unit is 0.2mm.

[0076] 2. Three-dimensional accuracy calibration: The laser detection system is activated to measure the position error. The deviation values ​​of the three-dimensional coordinates X, Y, and Z axes are displayed on an independent display screen. The operator adjusts the stator center line through the fine-tuning mechanism. The repeatability of the positioning is 0.2mm, and the three-dimensional coincidence error with the working generatrix is ​​≤±0.15mm.

[0077] Step 3: Rotor alignment and locking, rotor pre-positioning, and coaxiality calibration.

[0078] 1. Rotor pre-positioning: The base 211 moves into the rotor standby area, the chuck 31 clamps the rotor shaft end and confirms with an audible and visual alarm.

[0079] 2. Coaxiality fine adjustment: The coaxiality is monitored in real time by a laser electrical detection system. The servo drive pin 4 moves along the axis to compensate for the deviation. After the set coaxiality is ≤0.3mm, the rotor is hydraulically locked.

[0080] Step 4: Stator and rotor separation operation, dynamic disassembly control, and coordinated actuator action.

[0081] 1. Dynamic disassembly control: The base 211 moves horizontally at a preset speed (adjustable from 0.1 to 2 m / min), and the disassembly torque is monitored in real time. The threshold setting range is 50-500 N·m. An emergency stop alarm is triggered when the limit is exceeded.

[0082] Step 5: Component recycling and reset, material transfer and system reset.

[0083] 1. Material flow: The separated stator and rotor are output by conveyor rollers, with a conveying speed of 3m / min (variable frequency adjustable).

[0084] 2. System reset: All actuators return to their initial positions, and the lifting mechanism descends to a safe height of 150mm from the working surface.

[0085] Specifically, (1) the stator and rotor assembly, after the workers have disassembled the end cover bearings, is hoisted and placed in the stator tray, and transferred between the two clamping plates 10 by the conveyor rollers. The clamping plates 10 use clamping force to straighten the slightly skewed stator and rotor assembly. After the clamping force reaches a certain threshold, the clamping plates 10 are released and reset.

[0086] (2) The conveyor rollers continue to transfer the stator and rotor assembly to the movable frame and fix it in place. Input the lifting compensation value according to the difference between the stator and the central axis of the equipment, and lift the stator into place. After the stator is initially positioned, start the independent detection system to measure the stator position and display the position difference on a separate screen.

[0087] (3) The operator can adjust the three-dimensional coincidence accuracy of the stator center line and the working bus line by means of a precision fine-tuning mechanism according to the difference. The minimum compensation value that can be set for its lifting is 0.2mm, and the repeatability is also 0.2mm.

[0088] (4) The base 211 moves to the rotor standby area position.

[0089] (5) The chuck 31 inserts one end of the rotor shaft and triggers an alarm. The laser detection system above the ejector pin 4 determines the coaxiality with the center of the chuck 31 in real time and begins to move. After adjusting the distance, the ejector pin 4 is used to press the rotor shaft firmly, and then the brake is applied. When disassembly begins, the moving speed and stroke of the base 211 can be freely set, and a force feedback limit setting is provided. If an abnormality occurs, the machine will stop and alarm. It also has manual jog and automatic drive modes for easy operation.

[0090] (6) The rotor transition platform 20 is calibrated by the height detection mechanism and the rotor transition platform 20 is controlled to dock with the rotor. The device releases one end of the rotor shaft and pushes it away to the initial position. At the same time, the ejector pin 4 at the other end of the rotor shaft is released and retracted. The rotor transition platform 20 carries the rotor back to the initial position.
