Description

Technical Field

[0001] This invention belongs to the field of motor repair and manufacturing technology, specifically relating to a disassembly and assembly device for motor stators and rotors. Background Technology

[0002] In the manufacturing, assembly, routine maintenance, and troubleshooting of electric motors, the separation and assembly of the motor rotor and stator is a critical and frequently performed core process. The quality of this process directly determines the performance stability and service life of the motor. Especially for medium and large-sized electric motors and permanent magnet synchronous motors, the rotor extraction and assembly process faces multiple technical challenges due to their structural characteristics and operating conditions.

[0003] Currently, the operational methods for separating and assembling motor rotors in the industry are generally outdated. The mainstream approach involves using a crane or overhead crane to suspend one end of the motor rotor shaft, while multiple operators, armed with simple tools such as crowbars and copper bars, rely on their personal experience and feel to adjust the rotor's posture to maintain alignment, while slowly controlling the lifting equipment to complete the extraction and assembly. However, this method has many drawbacks: First, the alignment of the motor rotor and stator depends entirely on manual judgment, which cannot guarantee accuracy, and the risk of the motor rotor coming into contact with the stator core is extremely high; second, the operation requires multiple people to work together, resulting in high labor intensity and low work efficiency, and for medium and large motors, a single extraction and assembly operation often takes several hours to complete; third, there is a lack of effective safety protection mechanisms, and if the magnetic attraction causes the motor rotor to become uncontrollable or the lifting equipment to slip, it can easily lead to equipment damage or operator injury.

[0004] Therefore, there is an urgent need for a disassembly and assembly device for motor stators and rotors to solve the above problems. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: (1) The present invention uses a top rod and a pressure rod that can move up and down independently or synchronously relative to the stator positioning platform in the vertical direction. After the operator uses the stator positioning platform to position and fix the position of the motor stator, the motor rotor can be smoothly pushed out of the motor stator by the cooperation of the lifting and moving actions of the top rod and the pressure rod. At the same time, the motor rotor can be smoothly and accurately pressed into the motor stator in the fixed position. (2) This invention adopts a dual-path transmission structure, in which torque can be transmitted from input shaft one and input shaft two in the dual-output shaft reducer. One path drives the pressure rod to rise and fall through the dual-output shaft reducer and the first lead screw module, while the other path drives the top rod to rise and fall through the dual-output shaft reducer and the second lead screw module. Operators only need to manually switch the gear torque transmission path in the dual-output shaft reducer according to actual usage needs, and flexibly configure different transmission ratios so that the pressure rod and the top rod can move independently or synchronously. With the electronic positioning platform for positioning the motor stator and the rotor positioning fixture for positioning the motor rotor, high-precision and high-efficiency disassembly and assembly operations between the motor stator and the motor rotor can be achieved without complex electrical control.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention and therefore only show the components relevant to the present invention.

[0020] It should be noted that if directional indicators (such as up, down, bottom, top, etc.) are involved in this embodiment, these directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature. Unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances. Example 1

[0021] like Figures 1-10 As shown, a disassembly and assembly device for an electric motor stator and rotor includes a frame 1, a first lead screw module, a second lead screw module, and a stator positioning platform 2 for fixing the motor stator, all mounted on the frame 1. Specifically, the stator positioning platform 2 is a tooling fixture designed for the external features of the motor stator in the prior art, allowing the motor stator and its internal rotor to be placed vertically on the stator positioning platform 2. The input shaft of the first lead screw module is driven and connected to the output shaft 3 of the dual output shaft reducer. The dual output shaft reducer can drive the pressure rod 4, which is located at the output end of the first lead screw module, to press down vertically to one end of the motor rotor. The pressure rod 4 is also floating vertically connected to the output end of the first lead screw module. The input shaft of the second lead screw module is driven and connected to the output shaft 5 of the dual output shaft reducer. The dual output shaft reducer can drive the push rod 6, which is located at the output end of the second lead screw module, to lift vertically to the other end of the motor rotor. The dual output shaft reducer can drive the pressure rod 4 to move up and down relative to the pressure rod 4, drive the push rod 6 to move up and down relative to the pressure rod 4, and drive the pressure rod 4 and the push rod 6 to move up and down synchronously.

[0022] Specifically, the operator can place the motor stator and its internal rotor upright on the stator positioning platform 2, and fix the position of the motor stator using the stator positioning platform 2. At this time, the pressure rod 4 can be aligned with the top of the motor rotor along the axial direction of the motor rotor, while the push rod 6 can be aligned with the bottom of the motor rotor along the axial direction of the motor rotor. When it is necessary to remove the motor rotor embedded in the motor stator, the push rod 6 can be driven upward by the dual output shaft reducer to abut against the bottom of the motor rotor. The push rod 6 continuously applies force to the bottom of the motor rotor, and the direction of this force is parallel to the assembly direction between the motor rotor and the motor stator, which can drive the motor rotor to detach from the motor stator. It should be noted that before the push rod 6 pushes against the bottom of the motor rotor, the operator can drive the pressure rod 4 to flexibly abut against the top of the motor rotor using the dual output shaft reducer. That is, at this time, the pressure rod 4 can not only apply a certain pressure to the top of the motor rotor, but also float upward relative to the output end of the first lead screw module, and continuously apply downward pressure to the top of the motor rotor. When the motor rotor detaches from the motor stator, its state remains stable under the clamping action of the push rod 6 and the pressure rod 4. Subsequently, when the push rod 6 and the pressure rod 4 rise synchronously, the motor rotor can be transferred to the outside of the motor stator without damage. When assembling the motor stator and the motor rotor, it is only necessary to fix the position of the motor stator using the stator positioning platform 2, and then adjust the relative positions of the two ends of the motor rotor with the pressure rod 4 and the push rod 6. After the motor rotor is fixedly clamped by the pressure rod 4 and the push rod 6, the operator drives the pressure rod 4 and the push rod 6 to move synchronously down to precisely assemble the motor rotor and the motor stator.

[0023] In the above, such as Figure 1 , Figure 2 As shown, the first lead screw module includes two symmetrically arranged support seats 16 and 17 on the top side of the frame 1 along the stator positioning platform 2. Several guide shafts 18 arranged vertically are connected to the first support seat 16 and the second support seat 17, and one end of each guide shaft 18 facing away from the first support seat 16 or the second support seat 17 is connected to a fixed plate 19. The guide shafts 18 are movably inserted through and slidably connected to a lower pressure plate 20 suspended above the stator positioning platform 2. The pressure rod 4 is floatingly connected to the lower pressure plate 20 in the vertical direction. The lower pressure plate 20 is provided with several flange linear bearing seats corresponding to the guide shafts 18. The guide shafts 18 are slidably connected to the flange linear bearing seats to improve the smoothness of the lower pressure plate 20's vertical lifting and lowering and the accuracy of its linear motion.

[0024] A lead screw 21 is rotatably connected between the fixed plate 19 and the first support base 16, and a lead screw 22 is rotatably connected between the fixed plate 19 and the second support base 17. Lead screws 21 and 22 pass vertically through and are threaded onto the lower pressure plate 20. Specifically, in this embodiment, a flanged lead screw ball nut that can cooperate with lead screws 21 and 22 can be provided on the lower pressure plate 20. Lead screws 21 and 22 have the same specifications, and the flanged lead screw ball nuts used are also of the same specifications, to increase the stability of the connection between lead screws 21 and 22 and the lower pressure plate 20, and to increase the stability of the lower pressure plate 20's lifting and lowering movement. It should be noted that in this embodiment, the tops of lead screw 21 and lead screw 22 are driven and connected by synchronous belt 23. Synchronous belt 23 can achieve stable power transmission by setting a corresponding clamping wheel structure on fixed plate 19. Synchronous pulleys of the same specification are respectively set on the outer periphery of the top of lead screw 21 and lead screw 22. Synchronous belt 23 meshes with the synchronous pulleys on the outer periphery of the top of lead screw 21 and lead screw 22, causing lead screw 21 and lead screw 22 to rotate synchronously and at the same speed. Simultaneously, a helical gear 58 is set on the outer periphery of the bottom of lead screw 21 or lead screw 22, and a helical gear 59 meshing with helical gear 58 is set on the outer periphery of output shaft 3. Therefore, the circular motion of output shaft 3 can drive lead screw 21 and lead screw 22 to perform synchronous circular motion, thereby causing the lower pressure plate 20 to rise and fall smoothly in the vertical direction, and causing the pressure rod 4 to smoothly abut against the top of the motor rotor in the vertical direction.

[0025] In the above, such as Figure 1 , Figure 4As shown, the second lead screw module includes two sets of guide shaft assemblies symmetrically arranged on the bottom side of the frame 1 along the stator positioning platform 2. Each set of guide shaft assemblies includes several guide shafts 35 arranged vertically, that is, the guide shafts 35 in the two sets of guide shaft assemblies are parallel to each other. In this embodiment, the top of several guide shafts 35 is connected to the base of the frame 1, the bottom of several guide shafts 35 is connected to the fixing plate 36, and several guide shafts 35 are movably passed through and slidably connected to an upper top plate 37 placed below the stator positioning platform 2. The push rod 6 is vertically connected to the side of the upper top plate 37 facing downwards from the stator positioning platform 2. Among them, a lead screw 38 and a lead screw 49 are rotatably connected between the fixed plate 2 36 and the bottom side of the frame 1. The rotation axis of the lead screws 38 and 4 39 is parallel to the central axis of the guide shaft 2 35, and the lead screws 38 and 4 39 are symmetrically arranged along the top rod 6. The lead screws 38 and 4 39 pass through and are threaded to the upper top plate 37, and the bottom ends of the lead screws 38 and 4 39 are driven by a synchronous belt 2 40. The synchronous belt 2 40 can achieve stable power transmission by setting a corresponding clamping wheel structure on the fixed plate 2 36. A helical gear 3 41 is provided on the outer periphery of the top of the lead screw 3 38 or the lead screw 4 39, and a helical gear 4 42 that meshes with the helical gear 3 41 is provided on the outer periphery of the output shaft 2 5. It should be noted that in this embodiment, the upper top plate 37 is provided with flanged ball screw nuts that can be used with lead screws 38 and 4. Lead screws 1 21, 22, 38, and 4 39 have the same specifications, and the flanged ball screw nuts used are also of the same specifications. The top outer periphery of lead screws 38 and 4 39 are respectively provided with synchronous pulleys of the same specifications. Therefore, through the circular motion of the output shaft 2 5, lead screws 38 and 4 39 can be driven to perform synchronous circular motion, thereby causing the upper top plate 37 to rise and fall smoothly in the vertical direction, and causing the top rod 6 to abut against the bottom end of the motor rotor smoothly in the vertical direction.

[0026] In the above-described embodiment, the dual-output shaft reducer further includes a gear set one, a gear set two, a driving gear three, an input shaft one 7, and an input shaft two 8; wherein, a section of the outer periphery of the input shaft one 7 is provided with a spline tooth portion one 701, and a section of the outer periphery of the input shaft two 8 is respectively provided with a spline tooth portion two 801 and a spline tooth portion three 802; the driving gear one on the gear set one and the driving gear two on the gear set two are arranged coaxially, and the driven gear two on the driving gear one and the driven gear two on the gear set two are both meshed with the output shaft one 3 for transmission. Shaft 7 can move along its axial direction to engage with drive gear 1 or drive gear 2 via spline tooth 701; driven gear 1 and drive gear 3 are coaxially arranged on gear set 1, drive gear 3 engages with output shaft 2 5 via drive; input shaft 2 8 can move to engage with drive gear 3 via spline tooth 801 via spline tooth 801 via spline tooth 801 via drive gear 1 or drive gear 1 via spline tooth 801; and when spline tooth 801 engages with drive gear 1 via spline tooth 802 engages with drive gear 3 via spline tooth 802 via drive gear 3.

[0027] That is, when the operator can selectively move the input shaft 7 to engage the spline tooth 701 with the drive gear 2, or move the input shaft 8 to engage the spline tooth 801 with the drive gear 3, the output shaft 3 can be driven independently by the input shaft 7, and the output shaft 5 can be driven independently by the input shaft 8, thereby achieving rapid movement of the pressure rod 4 and the push rod 6 when they are not linked. When the operator operates the splined gear 801 on input shaft 7 to mesh with driven gear 1 and splined gear 802 to mesh with driving gear 3, and operates input shaft 7 to move splined gear 701 on it to mesh with driving gear 1 or driving gear 2, two gear train paths that can drive pressure rod 4 and push rod 6 to move together will be formed. It should be noted that the screwing directions between lead screw 1 21, lead screw 22 and lower pressure plate 20 and between lead screw 3 38, lead screw 4 and upper top plate 37 can meet the requirement of synchronous lifting and lowering when output shaft 1 3 and output shaft 2 5 are linked. In this embodiment, gear set 1 and gear set 2 can be composed of several gears with equal and / or unequal number of teeth, so that output shaft 1 3 and output shaft 2 5 have different transmission ratios while their output speeds are related, thereby meeting different actual use requirements. Example 2

[0028] Based on Embodiment 1, the gear train diagram of the dual-output shaft reducer is as follows: Figure 10As shown (in the diagram, only combinations of letters and numbers are used to represent the corresponding gear names). Specifically, gear set one includes: gear N1, gear N6, gear N7, gear N8, and gear N5, where gear N1 meshes with gear N6, gear N6 meshes with gear N7, gear N7 meshes with gear N8, and gear N8 meshes with gear N5. Gear N1 represents driving gear one, and gear N5 represents driven gear one. Gear set two includes: gear N9, gear N10, gear N11, gear N12, and gear N13. Gear N9 meshes with gear N10. Gear N10 and gear N11 are coaxially arranged compound gears, and gear N12 and gear N13 are coaxially arranged compound gears. N11 meshes with gear N... 12. Gear N9 represents driving gear two; gear N16 represents helical gear one 58 mounted on lead screw one 21; gear N15 represents helical gear two 59 mounted on output shaft one 3; gear N18 represents helical gear three 41 mounted on lead screw three; gear N17 represents helical gear four 42 mounted on output shaft two 5; gear N2 represents a gear structure mounted on output shaft one 3 that can mesh with gear N1; gear N14 represents a gear structure mounted on output shaft one 3 that can mesh with gear N13; gears N2 and N14 are coaxially arranged; gear N4 represents a gear structure mounted on output shaft two 5 that can mesh with gear N3. Gear N13 represents driven gear two; driving gear three is represented as gear N3 in the figure.

[0029] Among them, the gear shaft holes of gears N1 and N9 are respectively equipped with spline sleeves that can mesh with spline tooth section 701 for transmission, and the gear shaft holes of gears N5 and N13 are respectively equipped with spline sleeves that can mesh with spline tooth section 801 and spline tooth section 802 for transmission, so as to increase the stability and accuracy of torque transmission.

[0030] The number of teeth of the relevant gears includes, but is not limited to, the following implementation scheme: gear N1=48, gear N2=48, gear N3=48, gear N4=48, gear N5=48, gear N6=32, gear N7=32, gear N8=32, gear N9=40, gear N10=64, gear N11=16, gear N12=40, gear N13=16, gear N14=80, gear N15=17, gear N16=17, gear N17=17, gear N18=17.

[0031] The spline tooth 701 on output shaft 3, the spline tooth 801 on output shaft 5, and the spline tooth 802 on output shaft 5 can produce different combinations by meshing with different gear sets, as detailed below: When input shaft 7 meshes with gear N1, and input shaft 8 meshes only with gear N3, output shaft 3 and output shaft 5 are not connected. This meshing method enables rapid movement of pressure rod 4 and push rod 6 without linkage. The first torque transmission route is as follows: Input shaft 7 > Gear N1 > Gear N2 > Output shaft 3 > Gear N15 > Gear N16 > Lead screw 21 > Lead screw 22, with a transmission ratio of 1. The second torque transmission route is as follows: Input shaft 8 > Gear N3 > Gear N4 > Output shaft 5 > Gear N17 > Gear N18 > Lead screw 38 > Lead screw 49, with a transmission ratio of 1.

[0032] When input shaft 7 meshes with gear N1, and input shaft 8 meshes with gears N5 and N3 simultaneously, output shaft 3 and output shaft 5 are in a linked state. The first torque transmission route is as follows: Input shaft 7 > Gear N1 > Gear N2 > Output shaft 3 > Gear N15 > Gear N16 > Lead screw 21 > Lead screw 22, with a transmission ratio of 1. The second torque transmission route is as follows: Input shaft 7 > Gear N1 > Gear N6 > Gear N7 > Gear N8 > Gear N5 > Gear N3 > Gear N4 > Output shaft 25 > Gear N17 > Gear N18 > Lead screw 38 > Lead screw 49, with a transmission ratio of 1. Therefore, regardless of whether it is the torsional input shaft or the torsional input shaft 8, the output speeds of output shaft 3 and output shaft 5 are the same. This meshing method enables synchronous and rapid movement when the pressure rod 4 and the push rod 6 are linked.

[0033] When input shaft 7 meshes with gear N9, and input shaft 8 meshes with gears N5 and N3 simultaneously, output shaft 3 and output shaft 5 are in a linked state. The first torque transmission route is as follows: input shaft 7 > gear N9 > gear N10 > gear N11 > gear N12 > gear N13 > gear N14 > output shaft 3 > gear N15 > gear N16 > lead screw 21 > lead screw 22, with a transmission ratio of 20, which can amplify the end force by twenty times. The second torque transmission route is as follows: Output shaft 1 3 > Gear N14 > Gear N2 > Gear N1 > Gear N6 > Gear N7 > Gear N8 > Gear N5 > Gear N3 > Gear N4 > Output shaft 2 5 > Gear N17 > Gear N18 > Lead screw 3 38 > Lead screw 4 39. Since gears N14 and N2 are coaxial with output shaft 1 3 and rotate at the same speed, the transmission ratio between output shaft 1 3 and output shaft 2 5 is 1. Therefore, the end force of its torque transmission path can be amplified by twenty times. When input shaft 1 7 and input shaft 2 8 are manually operated by the operator, less force can be used to drive the motor rotor to disengage from the motor stator. This meshing method can achieve the deceleration linkage state when the pressure rod 4 and the push rod 6 are associated. Example 3

[0034] Based on Example 1, such as Figure 1 , Figure 3 As shown, the stator positioning platform 2 is slidably connected to the frame 1 in the horizontal direction. The stator positioning platform 2 and the frame 1 are slidably connected by multiple sets of linear guide rails, and buffers are respectively provided at both ends of the linear guide rails to limit the travel range of the stator positioning platform 2. Specifically, this embodiment uses two sets of linear guide rails symmetrically arranged along the center of gravity of the stator positioning platform 2, the motor stator, and the electronic rotor. The operator can move the position of the stator positioning platform 2 to facilitate its removal from directly below the lower pressure plate 20, thus facilitating the positioning and fixing of the motor stator. Meanwhile, the frame 1 is provided with several positioning blocks 9 corresponding to the moving path of the stator positioning platform 2. The stator positioning platform 2 is provided with positioning pins 10 that can be inserted and cooperate with the positioning blocks 9. The positions where the positioning blocks 9 and the positioning pins 10 inserted and cooperate with each other correspond to the disassembly and assembly positions of the motor rotor. That is, when the operator uses the positioning pins 10 to insert and cooperate with the group of positioning blocks 9, the position of the stator positioning platform 2 is fixed. At this time, the motor stator placed on the stator positioning platform 2 is located above the upper top plate 37 and below the lower pressure plate 20, and at this time, the motor rotor end located inside the motor stator is directly opposite the top rod 6 and the pressure rod 4.

[0035] Furthermore, such as Figure 1 , Figure 3 As shown, to facilitate the relocation of the motor rotor removed from the motor stator, in this embodiment, the disassembly and assembly equipment also includes a gantry bracket 11 slidably connected to the frame 1 in the horizontal direction. The gantry bracket 11 and the frame 1 can also be slidably connected by multiple sets of linear guide rails, and buffers are respectively provided at both ends of the linear guide rails to limit the travel range of the gantry bracket 11, thereby increasing the accuracy and stability of the linear movement of the gantry bracket 11. This allows the gantry bracket 11 to move smoothly and accurately above the stator positioning platform 2. The gantry bracket 11 is provided with a rotor positioning fixture 12 for supporting and engaging the motor rotor. The rotor positioning fixture 12 is a tooling fixture designed for the shape characteristics of the motor rotor in the prior art, which can be used to support and accurately position the motor rotor on the gantry bracket 11. In actual use, when the push rod 6 and the pressure rod 4 push the motor rotor out of the motor stator and move it upward, the gantry frame can be moved to make the rotor positioning fixture 12 accurately support and clamp and fix it to the outer periphery of the electronic rotor. After the push rod 6 and the pressure rod 4 release the position limitation on the motor rotor, the position of the motor rotor can be transferred by moving the gantry frame.

[0036] It should be noted that a push-pull rod 13 is provided on the gantry support 11 along its moving direction, and a positioning seat 14 corresponding to the moving path of the gantry support 11 is provided on the frame 1. A locking pin 15 is provided on the positioning seat 14, which can be inserted and engaged with the outer periphery of the push-pull rod 13. That is, when the gantry support 11 moves above the stator positioning platform 2, and the motor rotor positioned on the rotor positioning fixture 12 is aligned with the motor stator on the stator positioning platform 2 (at this time, the stator positioning platform 2 is locked in position by the insertion and engagement between the positioning pin 10 and the positioning block 9) along the assembly direction, the locking pin 15 on the positioning seat 14 can be precisely inserted and engaged with the positioning hole reserved on the push-pull rod 13. This allows operators to first position the motor rotor using the rotor positioning fixture 12 and the electronic stator using the stator positioning platform 2 when assembling the motor stator and rotor. Then, by moving the stator positioning platform 2 and the gantry bracket 11 to the corresponding positions, precise assembly can be performed by lifting and lowering the top rod 6 and the pressure rod 4 (including synchronous movement and independent movement). This improves both assembly efficiency and assembly accuracy of the motor stator and rotor. Example 4

[0037] Based on Example 1, such as Figure 6 , Figure 7 , Figure 8 As shown, the pressure rod 4 is inserted through and fixedly connected to the floating plate 26. Several guide shafts 27 that can move through the lower pressure plate 20 are symmetrically arranged on the top side of the floating plate 26 along the pressure rod 4. The guide shafts 27 can move vertically through the ballast base 24 set on the top side of the lower pressure plate 20. The top of each guide shaft 27 is provided with a limiting plate 25 that can overlap the top side of the ballast base 24. Each guide shaft 27 is provided with a support spring 2701 on its outer periphery that can elastically support the floating plate 26 and the ballast base 24, so as to realize the working requirement of the pressure rod 4 floatingly connected to the lower pressure plate 20 in the vertical direction.

[0038] Furthermore, when the operator needs to press down the motor rotor to assemble it with the motor stator, the support spring 2701 will be continuously compressed as the pressure rod 4 abuts against the top of the motor rotor until the pressure rod 4 reaches the limit of its upward floating stroke (the top of the pressure rod 4 abuts against the bottom side of the lower pressure plate 20). Only then will the force exerted by the pressure rod 4 on the top of the motor rotor reach its maximum.

[0039] It should be noted that, in this embodiment, in order to increase the accuracy of the vertical floating of the pressure rod 4 relative to the lower pressure plate 20, the guide shaft 27 and the ballast base 24 can be slidably connected by a flange linear bearing.

[0040] Furthermore, such as Figure 6 , Figure 7 , Figure 8As shown, in this embodiment, the ballast base 24 includes a base plate 57 detachably connected to the top side of the lower pressure plate 20 and a base plate 28 detachably connected to the top side of the base plate 57. A guide shaft 27 is movably inserted through the base plate 28, meaning that the guide shaft 27 and the base plate 28 can be slidably connected by a flange linear bearing. The limiting disc 25 can overlap the top side of the base plate 28 (or the flange linear bearing). Specifically, the base plate 57 has a plurality of stepped through holes 30 symmetrically arranged along the pressure rod 4 for inserting fastening bolts 29. The base plate 28 has a plurality of stepped through holes 32 symmetrically arranged along the pressure rod 4 for inserting fastening bolts 31. The fastening bolts 29 can be threaded to the lower pressure plate 20, and the fastening bolts 31 can be threaded to the base plate 57. The length extension directions of the stepped through holes 30 and 32 are perpendicular to each other and perpendicular to the vertical direction. Furthermore, the lower pressure plate 20 is rotatably connected to an adjusting bolt 33 that can be threadedly connected to the base plate 57 along the length extension direction of the stepped through hole 30, and the base plate 57 is rotatably connected to an adjusting bolt 34 that can be threadedly connected to the base plate 28 along the length extension direction of the stepped through hole 32. That is, by loosening the fastening bolts 29 and 31, and correspondingly twisting the adjusting bolts 33 and 34, the position of the base plate 57 relative to the lower pressure plate 20 can be adjusted in one direction, and the position of the base plate 28 relative to the base plate 57 can be adjusted in another direction, so that the pressure rod 4 can be finely adjusted within the stroke range of the base plate 57 and the base plate 28.

[0041] It should be noted that, to facilitate operators' observation of the specific details of the fine-tuning of the position of lever 4, such as... Figure 5 , Figure 6 , Figure 7 As shown, dial indicators can be installed on the upper pressure plate and the base plate 57 respectively. The probe end of the dial indicator can abut against the side of the base plate 57 along the moving direction of the corresponding base plate 57 and abut against the side of the base plate 28 along the moving direction of the base plate 28. The detailed information on the fine adjustment of the position of the pressure rod 4 can be obtained by the numerical change fed back by the corresponding dial indicator.

[0042] Similarly, in this embodiment, to facilitate fine-tuning of the position of the push rod 6, such as... Figure 5As shown, the end of the top rod 6 is connected to the base plate 3 43, the base plate 3 43 is detachably connected to the base plate 44, and the base plate 44 is detachably connected to the upper top plate 37. Specifically, the base plate 3 43 has several stepped through holes 3 46 symmetrically arranged along the top rod 6 for passing through fastening bolts 3 45, the base plate 4 44 has several stepped through holes 4 48 symmetrically arranged along the top rod 6 for passing through fastening bolts 4 47, the base plate 4 44 has adjustable bolts 3 49 rotatably connected to the base plate 3 43 along the length extension direction of the stepped through holes 3 46, and the upper top plate 37 has adjustable bolts 4 50 rotatably connected to the base plate 4 44 along the length extension direction of the stepped through holes 4 48. The length extension direction of the stepped through holes 3 46 and the length extension direction of the stepped through holes 4 48 are perpendicular to each other and perpendicular to the vertical direction. Meanwhile, the specific details of the fine-tuning of the position of the push rod 6 can also be achieved through the implementation method of the dial indicator described above.

[0043] The push rod 6 and pressure rod 4 are capable of fine-tuning their positions, allowing operators to adjust their centerlines to coincide with the centerline of the motor rotor before rotor removal and installation, ensuring the stability of the push rod 6 and pressure rod 4 in clamping and fixing the motor rotor. During the assembly of the motor rotor and stator, after the push rod 6 and pressure rod 4 have clamped and fixed the motor rotor, the position of the motor rotor relative to the motor stator can be precisely adjusted to ensure that the centerline of the motor rotor coincides with the centerline of the motor stator, fundamentally preventing "rotor rubbing" from occurring. Example 5

[0044] Based on Example 1, such as Figure 1 , Figure 10As shown, the frame 1 is equipped with a modular counterweight unit 1 51 for balancing the resistance encountered when the lower pressure plate 20 moves upward, and a modular counterweight unit 2 52 for balancing the resistance encountered when the upper top plate 37 moves upward. Modular counterweight unit 1 51 and modular counterweight unit 2 are conventional technologies known in the art. They achieve flexible adjustment of the counterweight weight by disassembling the integral counterweight into standardized counterweight modules of uniform specifications that can be individually or selectively combined and associated, and cooperating with the connecting mechanism and mounting base. In this embodiment, the force-bearing end of modular counterweight unit 1 51 can be connected to the lower pressure plate 20 via steel cable 1 53 and pulley block 1 54, and the force-bearing end of modular counterweight unit 2 52 can be connected to the upper top plate 37 via steel cable 2 55 and pulley block 2 56. Specifically, in actual use, the lifting and lowering action of the lower pressure plate 20 is illustrated, and the same applies to the upper top plate 37. When the operator manually drives the lower pressure plate 20 downward by operating the dual output shaft reducer, the corresponding number of standardized counterweight modules in the modular counterweight unit 51 also rise accordingly. Conversely, when the lower pressure plate 20 moves upward, the corresponding number of standardized counterweight modules in the modular counterweight unit 51 also rise accordingly. The weight of the corresponding number of standardized counterweight modules is relatively close to that of the lower pressure plate 20, with a weight difference of 0.1 to 0.5 kg. This reduces the adverse effects of the lower pressure plate 20's own weight on the transmission structure and saves the operator's labor intensity during manual operation.

[0045] Working Principle: This invention employs a dual-path transmission structure, where torque is transmitted in two paths from input shaft 7 and input shaft 8 of the dual-output shaft reducer: one path drives the pressure rod 4 to rise and fall via the dual-output shaft reducer and the first lead screw module; the other path drives the top rod 6 to rise and fall via the dual-output shaft reducer and the second lead screw module. Operators can manually switch the gear torque transmission paths in the dual-output shaft reducer according to specific scenarios and flexibly configure different transmission ratios, enabling the pressure rod 4 and the top rod 6 to move independently or synchronously. Combined with the electronic positioning platform for positioning the motor stator and the rotor positioning fixture 12 for positioning the motor rotor, high-precision and high-efficiency disassembly and assembly operations between the motor stator and rotor can be achieved without complex electrical control.

[0046] Based on the preferred embodiments of the present invention described above, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
