Description

Technical Field

[0001] This invention relates to the field of motor disassembly and separation equipment technology, and in particular to a stator and rotor separation workbench. Background Technology

[0002] When disassembling and repairing the stator and rotor of an electric motor, it is necessary to independently position the stator and rotor, and move them relative to each other in the axial direction to achieve disassembly and separation.

[0003] Most current stator and rotor disassembly and separation mechanisms separate the two by fixing the stator and moving the rotor assembly. However, this method has the following drawbacks:

[0004] First, it requires a C-shaped mechanism to clamp the upper and lower centers of the rotor, which requires a lot of force to clamp the rotor. The structure requires high precision and strength, and is bulky. It is necessary to overcome gravity to lift it, which makes it impossible to be simple and lightweight, and the cost is high.

[0005] Secondly, due to the large magnetic attraction between the stator and rotor, a significant amount of magnetic attraction needs to be overcome during disassembly and separation. Furthermore, because the C-shaped mechanism itself is bulky, a large lifting force is required when the C-shaped mechanism lifts the rotor together. Therefore, a manual reducer is generally needed for assisted lifting during disassembly, resulting in high operating costs. Moreover, during the lifting of the C-shaped mechanism and rotor, the bulkiness of the C-shaped mechanism can easily cause radial displacement between the rotor and stator, making it easier for the stator and rotor to adhere together, thus increasing the difficulty of disassembly. In addition, the radial displacement of the stator and rotor can easily cause them to rub against each other, increasing the failure rate of disassembly and assembly.

[0006] Secondly, maintenance personnel need to perform regular maintenance on the manual reducer, which will affect subsequent disassembly work. At the same time, during the maintenance of the manual reducer, bolts need to be removed and the coaxiality and perpendicularity of the equipment need to be re-tested, which consumes a lot of time, effort and manpower, is extremely inefficient, and may also cause safety problems due to missing bolts. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a stator-rotor separation workbench, so as to realize convenient and reliable disassembly and separation of stator and rotor, improve positioning accuracy and disassembly efficiency, with a compact and reliable structure, saving space and cost, and good compatibility.

The stator lifting plate is located above the mounting groove of the lifting slide. The lifting slide has support rails on the left and right sides of the mounting groove. The two support rails support the left and right ends of the bottom surface of the stator lifting plate. The left and right ends of the top surface of the stator lifting plate are detachably pressed by the first clamping components located on the outside of the two support rails, thereby achieving a detachable connection between the stator lifting plate and the lifting slide.

[0037] The embodiments of the present invention are described in detail below. These embodiments are implemented based on the technical solution of the present invention, and provide detailed implementation methods and specific operation processes. However, the scope of protection of the present invention is not limited to the following embodiments.

[0038] See Figures 1 to 13 This embodiment discloses a stator-rotor separation workbench. The rotor 1 is rotatably mounted on the flywheel housing 2. The workbench includes a body 3, on which a rotor fixing mechanism and a stator clamping mechanism are provided.

[0039] The rotor fixing mechanism includes an upper rotor pressing assembly 4 and a lower rotor clamping assembly 5 arranged opposite to each other. The flywheel housing 2 is clamped by the lower rotor clamping assembly 5. The upper rotor pressing assembly 4 is movably installed on the fuselage 3 and can slide vertically along the fuselage 3. The upper rotor pressing assembly 4 presses the top of the rotor 1 downward to fix the rotor 1 on the fuselage 3.

[0040] The upper rotor pressing assembly 4 includes a first base 6 fixed on the machine body 3, and a pressing rod 7 slidably disposed on the first base 6 and able to slide vertically along the first base 6. The pressing rod 7 is driven to slide vertically along the first base 6 through a linkage mechanism. The crank-rocker mechanism includes a connecting rod 8 and a Z-shaped bending rod 9 located in the same vertical plane. A horizontal top plate 10 is fixed to the top of the top pressure rod 7. The Z-shaped bending rod 9 includes a first rod segment, a second rod segment, and a third rod segment connected in sequence. A hinge hole is provided at the junction of the first rod segment and the second rod segment. A strip hole 11 is opened at the end of the first rod segment. The hinge hole of the Z-shaped bending rod 9 is hinged to the first base 6 through a first hinge shaft 12. The upper end of the connecting rod 8 is hinged to the horizontal top plate 10 at the top of the top pressure rod 7. The lower end of the connecting rod 8 is hinged to the strip hole 11 of the first rod segment through a second hinge shaft 13. The second hinge shaft 13 can slide in the strip hole 11 of the first rod segment. An operating handle 14 perpendicular to the third rod segment is provided at the end of the third rod segment. The Z-shaped bending rod 9 is rotated around the first hinge shaft 12 by the operating handle 14, thereby pulling the top pressure rod 7 vertically through the connecting rod 8. The top of the fuselage 3 is equipped with a first balance hanger 15. The first lifting ring at the top of the top pressure rod 7 is connected to the first balance hanger 15 by a hanging rope to achieve balanced suspension of the top pressure rod 7 and prevent the top pressure rod 7 from falling accidentally.

[0041] The top pressure rod 7 is provided with two sets of locking positions, one above the other. A locking sleeve 16 is fixed on the first base 6. The top pressure rod 7 slides through the internal channel of the locking sleeve 16. The locking sleeve 16 is provided with a locking structure. The locking structure cooperates with the two sets of locking positions of the top pressure rod 7 to lock the top and bottom positions of the top pressure rod 7, that is, to lock the idle position and the working position of the top pressure rod 7. When the top pressure rod 7 is in the working position, the bottom of the top pressure rod 7 is pressed against the top of the rotor 1. When the top pressure rod 7 moves up to the idle position, the top pressure rod 7 moves upward and disengages from the rotor 1, thereby releasing the rotor 1.

[0042] Each locking position of the top pressure rod 7 has a main locking hole 17 and a secondary locking hole 18. The secondary locking hole 18 extends radially through the top pressure rod 7, and the main locking hole 17 and the secondary locking hole 18 are perpendicularly connected. The locking structure on the locking sleeve 16 includes a main locking structure and a secondary locking structure. The secondary locking structure includes a secondary protrusion that can elastically extend and retract. The secondary protrusion of the secondary locking structure is engaged with the secondary locking hole 18 of the corresponding locking position on the top pressure rod 7. The main locking structure includes a main protrusion 19 that can elastically extend and retract. The main protrusion 19 of the main locking structure is engaged with the main locking hole 17 of the corresponding locking position on the top pressure rod 7. The depth to which the main protrusion 19 is embedded in the main locking hole 17 is greater than the depth to which the secondary protrusion is embedded in the secondary locking hole 18. The secondary locking structure can employ a ball-head plunger, with its positioning ball automatically embedded into the secondary locking hole 18 of the top pressure rod 7. The primary locking structure can employ a positioning spring pin, with manual control over whether the positioning spring pin is engaged with the primary locking hole 17 of the top pressure rod 7. This dual locking structure, with primary and secondary locking structures cooperating with the primary and secondary locking holes 18 respectively, ensures the stable locking of the top pressure rod 7 in both the idle and working positions, guaranteeing the locking effect and preventing the top pressure rod 7 from slipping off the locking structure and causing locking failure. This ensures the stable pressing of the top pressure rod 7 onto the rotor 1, thereby guaranteeing the normal operation of the separation worktable.

[0043] The lower rotor clamping assembly 5 includes a second base 20 fixed on the body 3. A positioning ring 21 is fixed on the second base 20. The positioning ring 21 can be installed on the second base 20 by screw connection. Two second positioning pins 22 are distributed circumferentially on the top surface of the positioning ring 21. The top surface of the positioning ring 21 is a support surface. The support surface at the top of the positioning ring 21 supports the bottom surface of the flywheel housing 2. The two second positioning pins 22 respectively cooperate with the two pin holes of the flywheel housing 2 to realize the positioning of the flywheel housing 2. Several mounting posts 23 with mounting holes are distributed circumferentially on the bottom surface of the flywheel housing 2. At least two second pressing assemblies 24 are arranged circumferentially on the second base 20 around the positioning ring 21. The pressure plates 25 of each second pressing assembly 24 are detachably pressed against the top surface of the corresponding mounting post 23 on the flywheel housing 2 to realize the pressing and clamping of the flywheel housing 2. The second base 20 has a clearance hole 26 in the space inside the positioning ring 21, and the second base 20 has a notch in front of the clearance hole 26. The positioning ring 21 also has a notch in front. This is designed to expose the bottom of the rotor 1 downwards, so that the operator can disassemble the bolts at the bottom of the rotor 1.

[0044] The stator clamping mechanism is located above the lower rotor clamping assembly 5. The stator clamping mechanism includes a stator hoisting clamping assembly and a separation lifting slide assembly. The stator hoisting clamping assembly includes a stator hoisting plate 27, which is suspended on the connecting frame 50 and can slide vertically along the connecting frame 50. A guide seat 28 is fixed on the connecting frame 50. The stator hoisting plate 27 is slidably mounted on the guide seat 28 by at least two guide rods 29 at the top. The top ends of each guide rod 29 pass upward through the guide seat 28 and are connected by a hanging top plate 30. The hanging top plate 30 is suspended by a second balance hanger 31 installed on the top of the connecting frame 50 through a suspension rope, thereby achieving balanced suspension of the stator hoisting plate 27 and preventing the stator hoisting plate 27 from falling accidentally. The connecting frame 50 is movably mounted on the machine body 3 and can move along the horizontal direction of the machine body 3. The connecting frame 50 is mounted on the machine body 3 via a cross slide rail assembly 32, which allows the connecting frame 50 to slide along the left-right and front-back directions of the machine body 3. The bottom of the stator lifting plate 27 is provided with several clamping block assemblies 33 for clamping the stator 51. The clamping block assembly 33 includes a mounting rod 34 and a clamping block 35. The mounting rod 34 is fixed to the bottom of the stator lifting plate 27. The clamping block 35 is rotatably mounted on the bottom of the mounting rod 34 via a third hinge shaft 36. A clamping groove 37 is opened on one side of the clamping block 35 to expose the bottom of the mounting rod 34. The stator 51 is provided with a flange 38 around its circumference. Multiple screw holes 39 are opened on the flange 38. The clamping block assembly 33 is engaged with the flange 38 of the stator 51 through the clamping groove 37 of the clamping block 35. The bottom of the mounting rod 34 is embedded into the screw holes 39 of the flange 38 of the stator 51. The clamping block 35 is locked on the mounting rod 34 by the locking structure 40, thereby achieving the clamping of the stator 51. The locking structure 40 can be a spring plunger. The positioning pin of the spring plunger is embedded in the locking hole on the mounting rod 34 to lock the clamping block 35 on the mounting rod 34, so that the clamping block 35 cannot rotate freely.

[0045] The separation lifting slide assembly includes a lifting slide 41 that is slidably mounted on the machine body 3 and can slide vertically along the machine body 3. The separation lifting slide assembly also includes a lifting drive mechanism, which includes a rocker arm wheel 42 and a lead screw 43. The rocker arm at the center of the rocker arm wheel 42 extends horizontally and is rotatably mounted on the machine body 3. The lead screw 43 extends vertically and is rotatably mounted on the machine body 3. One end of the rocker arm and the bottom end of the lead screw 43 are connected by a bevel gear pair 44. A nut is threaded onto the lead screw 43. The lifting slide 41 is fixedly connected to the nut. By rotating the rocker arm wheel 42, the rocker arm is rotated. Under the transmission action of the bevel gear pair 44, the lead screw 43 is driven to rotate. The rotating lead screw 43 drives the nut to move vertically, thereby driving the lifting slide 41 to move vertically, realizing the vertical lifting of the lifting slide 41. The stator lifting plate 27 is detachably connected to the lifting slide 41. The lifting slide 41 moves upward, causing the stator lifting plate 27 to move upward as well, thereby causing the stator 51 held by the stator lifting plate 27 to move upward as well, thus realizing the separation of the stator 51 from the rotor 1.

[0046] The lifting slide 41 has a mounting groove 45 in the middle of its front side. The stator lifting plate 27 is located above the mounting groove 45 of the lifting slide 41. The lifting slide 41 is provided with support rails 46 on the left and right sides of the mounting groove 45. The two support rails 46 support the left and right ends of the bottom surface of the stator lifting plate 27. The first clamping component located on the outside of the two support rails 46 can detachably clamp the left and right ends of the top surface of the stator lifting plate 27, thereby realizing the detachable connection between the stator lifting plate 27 and the lifting slide 41. The first clamping component can be a manual clamp. Each of the two support guide rails 46 is provided with a first positioning pin 47. The two first positioning pins 47 cooperate with the two positioning holes 48 on the stator lifting plate 27 to achieve the positioning of the stator lifting plate 27. The bottom left and right ends of the stator lifting plate 27 are provided with L-shaped limiting blocks 49. The horizontal sections of the two limiting blocks 49 are located below the lifting slide 41. When the stator lifting plate 27 is connected to the lifting slide 41, the vertical distance between the horizontal section of the limiting block 49 and the bottom surface of the lifting slide 41 is greater than the vertical distance of the first positioning pin 47 protruding from the top surface of the support guide rail 46.

[0047] The working process of the stator-rotor separation stage provided in this embodiment is as follows:

[0048] When the motor needs repair, the flywheel housing 2 at the bottom of the motor is placed on the positioning ring 21 of the lower rotor clamping assembly 5, so that the two pin holes of the flywheel housing 2 engage with the two second positioning pins 22 of the positioning ring 21 to position the flywheel housing 2. Then, the pressure plates 25 of each of the second clamping assemblies 24 are pressed against the top surface of the corresponding mounting post 23 on the flywheel housing 2 to clamp and hold the flywheel housing 2. Then, the crank rocker mechanism of the upper rotor pressing assembly 4 is operated to lift the operating handle 14 upward, which drives the Z-shaped bending rod 9 to rotate around the first hinge shaft 12. The connecting rod 8 pulls the pressing rod 7 downward until the lower end of the pressing rod 7 presses against the top of the rotor 1 shaft. At this time, the pressing rod 7 is in the working position and is locked in the working position by the locking structure. At this time, the clamping and fixing of the rotor 1 and the flywheel housing 2 is completed.

[0049] Then, the stator clamping mechanism is activated, and the stator lifting plate 27 is pressed onto the lifting slide 41 by the two first clamping components, so that the stator lifting plate 27 and the lifting slide 41 are fixed together. Then, the rocker arm wheel 42 of the lifting drive mechanism is rotated, which drives the lifting slide 41 to move down, thereby driving the stator lifting plate 27, which is fixed together with the lifting slide 41, to move down together until the multiple sets of clamping block assemblies 33 at the bottom of the stator lifting plate 27 descend to the flange 38 of the stator 51. At this time, the bottom of the mounting rod 34 is inserted into the screw through hole 39 of the flange 38 of the stator 51. Each clamping block 35 is flipped so that the clamping groove 37 of the clamping block 35 is locked outside the flange 38 of the stator 51. Then, the clamping block 35 is locked on the mounting rod 34 by the locking structure 40, thus completing the clamping of the stator 51 by each clamping block assembly 33. Then, the rocker arm wheel 42 of the lifting drive mechanism is rotated in the opposite direction, which drives the lifting slide 41 to rise, thereby driving the stator hoisting plate 27 and the stator 51 it holds to rise together. Since the rotor 1 and flywheel housing 2 are pressed and held on the body 3, the stator 51 will gradually separate from the rotor 1 during the rising process of the stator 51. When the stator 51 is separated from the part of the stator and rotor 1 with the strongest magnetic force, the rocking force of the rocker arm wheel 42 is weakened, and the separation and disassembly of the stator and rotor is completed.

[0050] Then, press down the operating handle 14 of the crank rocker mechanism to pull the top pressure rod 7 upward, causing the top pressure rod 7 to leave the rotor 1. When the top pressure rod 7 moves to the idle position, it is locked. Unlock the two first clamping components and disconnect the stator lifting plate 27 from the lifting slide 41. Manually lift the stator lifting plate 27 so that it disengages from the first positioning pins 47 on the two support guide rails 46. At this time, the horizontal section of the limiting block 49 contacts the bottom surface of the lifting slide 41, which can limit the upward lifting distance of the stator lifting plate 27 and prevent the stator 51 it holds from touching related components due to excessive upward lifting distance. At this point, the stator lifting plate 27 can move freely in the horizontal plane. The cross slide rail assembly 32 drives the connecting frame 50 forward, causing the stator lifting plate 27 and the stator 51 it holds to slide forward together. The stator 51 is moved to the top of the transfer trolley on the front side of the separation workbench. Then, the second balancing crane 31 drives the stator lifting plate 27 and the stator 51 downwards, placing the stator 51 on the placement platform of the transfer trolley. The transfer trolley then pulls the stator 51 away for subsequent maintenance. Next, the pressure plates 25 of each of the second clamping assemblies 24 are opened, releasing the flywheel housing 2. The rotor 1 and flywheel housing 2 are then moved away by a forklift for further maintenance.

[0051] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
