Description

Technical Field

[0001] The present invention relates to the technical field of motors, and in particular to a motor stator flipping device. Background Art

[0002] In the motor production process, the stator needs to be flipped over to facilitate subsequent assembly or testing.

[0003] Referring to the Chinese patent document of the authorization announcement number CN221916193U and the announcement date October 29, 2024, the name is a stator turning machine with high safety. The device includes a bottom plate, a turning machine base and a turning machine turning wheel. The stator is placed on the upper surface of the turning machine turning wheel. The turning machine turning wheel rotates, driving the stator on the turning machine turning wheel to rotate. During the rotation, the stator is flipped from an axial vertical placement state to an axial horizontal placement state, thereby realizing the flipping of a large stator.

[0004] With regard to the above-mentioned related technologies, due to the limitation of the accuracy of the stator movement process, when the stator is placed on the upper surface of the flip wheel disk, there may be a gap between the circumferential outer wall of the stator and the side of the flip wheel disk. During the flipping of the stator, as the inclination angle changes, the supporting force of the upper surface of the flip wheel disk on the stator will also change. When a certain angle is reached, the stator slides relative to the upper surface, and the stator moves toward the side and collides with the side. This impact may cause damage to the internal structure of the stator, posing a safety hazard. Moreover, during the flipping of the stator, the component force of the stator's gravity is continuously converted and acts on the flipping device. Due to a certain rotation error in the motor speed, the component force conversion process is unstable. When the conversion amount is large, the component force has a certain impact on the flipping device, which may cause damage to the flipping device. Summary of the invention

[0005] In view of this, the present invention provides a motor stator flipping device, aiming to solve the technical problems in the prior art that the stator is subjected to large impact force during flipping and the flipping process is unstable, which easily leads to damage to the stator and the flipping device.

[0006] In order to solve the above technical problems, the present invention provides a motor stator flipping device, which adopts the following technical solutions: a motor stator flipping device, including a flipping machine base, a flipping wheel and a flipping driving member; A sliding plate connected to the upper surface of the flip wheel disc in a left-right sliding direction, a bottom plate connected to the sliding plate in a vertical sliding direction, and a side plate connected to the side of the flip wheel disc in a horizontal sliding direction, wherein two sets of support wheels capable of abutting against the outer circumferential wall of the stator are arranged on the side plate; A hydraulic cylinder 1 is arranged at the bottom of the sliding plate, the output end of which is connected to the bottom plate, a buffer spring is placed between the bottom surface of the bottom plate and the sliding plate, a hydraulic cylinder 2 is arranged on the side of the flip wheel, the output end of which faces rightward and is connected to the left side of the side plate, and the hydraulic cylinder 1 and the hydraulic cylinder 2 are connected through a connecting pipe; A vertical plate is connected to the upper surface of the flip wheel disc and is located on the right side of the sliding plate in a sliding manner in the left and right directions. Two support rods are connected to the left side of the vertical plate in a sliding manner. The left ends of the two support rods are connected to support wheels 2 that can abut against the outer circumferential wall of the stator. A compression spring sleeved on the support rod is arranged between the support wheel 2 and the left side of the vertical plate. A control component is arranged between the sliding plate and the vertical plate, which can drive the vertical plate and the sliding plate to move synchronously when the flip wheel rotates.

[0007] By adopting the above technical solution, the stator is initially placed on the bottom plate. During the falling process of the stator, the buffer spring and the hydraulic cylinder 1 can both play a buffering role to reduce the impact force received by the stator during the falling process; the hydraulic cylinder 1 is connected to the hydraulic cylinder 2, the stator and the bottom plate gradually descend, the side plate gradually extends, and the support wheel 1 abuts against the circumferential outer wall of the stator, so that when the subsequent flip wheel rotates, the support wheel 1 continues to provide support force to the stator, thereby improving the previous situation where the stator directly collides with the side after sliding, and avoiding damage to the internal structure of the stator as much as possible.

[0008] At the same time, during the rightward movement of the side plate, the side plate pushes the stator and the sliding plate, and the sliding plate moves to the right, so that the support wheel 2 abuts against the circumferential outer wall of the stator, and the support wheel cooperates with the support wheel 1 and the bottom plate to limit the stator at multiple angles, thereby improving the stability of the stator during the flipping process and reducing the risk factor; among them, the compression spring can improve the flexibility of the device, facilitate leaving operating space for the control part, and can reduce the hard contact between the device and the stator, which is beneficial to reduce the occurrence of impact on the stator.

[0009] During the stator flipping process, the side plates retract and the bottom plate extends under the action of the component force of the stator's gravity, which can buffer the change of the component force of the stator's gravity during the stator flipping process, make the component force conversion process more stable, improve the safety of the flipping process, and reduce the risk of device damage. In addition, during the extension of the bottom plate, the bottom plate pushes the stator to make the stator slide along the support wheel, which is convenient for subsequent processing and operation of the stator.

[0010] Optionally, the control member includes a double-headed cylinder connected to the right side of the sliding plate, the two output ends of the double-headed cylinder are respectively facing the front and rear directions, the two output ends of the double-headed cylinder are connected to the first stopper, and the bottom of the vertical plate is provided with two second stops slidably plugged into the top of the flip wheel, and the first stopper can abut against the second stopper; A return spring extending in the left-right direction and enabling the stopper 2 to have a rightward movement tendency is arranged between the stopper 2 and the flip wheel disc.

[0011] By adopting the above technical solution, during the right movement of the sliding plate, the double-headed cylinder controls block one to retract, so that block one moves to the right side of block two, and block one extends out and abuts against block two. During the flipping process, the sliding plate moves synchronously with the stator and approaches the side plate under the action of static friction, and block one pushes block two, so that support wheel two moves synchronously with the stator, and the stator is kept tightly held during the flipping process, thereby improving the stability of the device. A reset spring is provided, and after block one is separated from block two, the reset spring pulls block two, so that block two and the vertical plate move to the right side of the flip wheel disc for easy reset.

[0012] Optionally, the flip wheel is provided with a rotating member capable of controlling the vertical plate to rotate relative to the flip wheel.

[0013] By adopting the above technical solution, the flexibility of the device is improved and the vertical plate is prevented from obstructing other subsequent operation processes as much as possible.

[0015] By adopting the above technical solution, it is convenient to control the rotation of the vertical plate.

[0016] Optionally, the hydraulic cylinder 1 is connected to the connecting pipe via a damping hole.

[0017] The adoption of the technical solution is helpful to buffer the falling process and the turning process of the stator.

[0018] Optionally, the side of the flip wheel disc is provided with an anti-slip block located above the side plate and capable of abutting against the stator.

[0019] The adoption of the above technical solution is helpful to improve the stability of the device.

[0021] By adopting the above technical solution, the flexibility of the device is improved.

[0022] Optionally, a tension spring extending in the left-right direction and enabling the sliding plate to have a tendency to move rightward is provided between the sliding plate and the flip wheel.

[0023] By adopting the above technical solution, the sliding plate is easy to reset, which is conducive to the repeated use of the device.

[0024] Optionally, a through hole is provided in the middle of the sliding plate which passes through from top to bottom, a sliding rod extending in the front-to-back direction is provided in the through hole, a support block is provided on the sliding rod which slides axially along the sliding rod, hydraulic cylinder 1 is connected to the bottom surface of the support block, a bottom plate is provided above the support block, a through groove is provided at the output end of hydraulic cylinder 1 for the sliding rod to pass through, and center springs are provided at both ends of the sliding rod.

[0025] By adopting the above technical solution, the defects in the stator falling process are compensated. If the stator is placed on the bottom plate and the initial position is offset, the stator and the bottom plate can be centered under the action of the centering spring, support wheel one and support wheel two, thereby improving the stability of the flipping process.

[0026] In summary, the present invention includes the following beneficial technical effects: 1. The lowering process of the stator is buffered by the buffer spring and the hydraulic cylinder 1, and the flipping process of the stator is buffered by the hydraulic cylinder 1 and the hydraulic cylinder 2.

[0027] 2. The rotating part controls the rotation of the vertical plate, which can leave enough operating space for the processing and operation of the stator, making it easy to use and convenient.

[0028] 3. Providing a tension spring and multiple springs is beneficial to the automatic resetting of the structure, facilitates repeated use, improves the fault tolerance of the device, reduces the hard contact between the device and the stator, and thus reduces the impact force on the stator.

[0029] 4. A centering piece is provided to compensate for the defects in the stator falling process.

[0032] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0033] The following is combined with Figure 1 -Attached Figure 7 The present invention is described in further detail.

[0034] The embodiment of the present invention discloses a motor stator flipping device. Figures 1 to 7 A motor stator flipping device includes a flipping machine base 1, a flipping wheel 2, a flipping driving member 3, a buffer component and a clamping component.

[0035] Reference Figure 1 and Figure 2The turning machine base 1 is placed on the horizontal ground, and the top surface of the turning machine base 1 is provided with an opening for the turning wheel 2 to rotate. The turning drive member 3 is arranged between the turning machine base 1 and the turning wheel 2, and is used to drive the turning wheel 2 to rotate. Specifically, the turning drive member 3 includes a driving shaft 31, a gear 32, a rack 33 and a rotating wheel 34. The driving shaft 31 is rotatably connected to the inside of the turning machine base 1. There are two gears 32, and the two gears 32 are respectively connected to the two ends of the driving shaft 31. The rack 33 is connected to the circumferential outer wall of the turning wheel 2, and the rack 33 is meshed with the gear 32. There are two racks 33, and the two racks 33 are arranged in parallel. In order to ensure the clarity of the diagram, only one rack 33 is drawn in the diagram. There are four rotating wheels 34 and they are arranged in a rectangular shape inside the turning machine base 1. The rotating wheel 34 abuts against the circumferential outer wall of the turning wheel 2.

[0036] By means of an external rotating driving element, such as a rotating motor, the driving shaft 31 is driven to rotate, the gear 32 rotates synchronously with the driving shaft 31, the gear 32 drives the rack 33, so that the flip wheel 2 rotates, and the rotating wheel 34 plays a supporting role, which is conducive to the stable rotation of the flip wheel 2. In this embodiment, the cooperation of the gear 32 and the rack 33 can achieve precise position control, and can withstand a large load, which is conducive to providing a smooth force transmission, reducing impact and vibration, and flexible installation. Furthermore, in other embodiments, the flip driving member 3 can also use other methods to drive the flip wheel 2 to rotate, and only one example is given here.

[0037] Reference Figure 3 and Figure 4 The buffer assembly includes a sliding plate 4, a bottom plate 5, a side plate 6, a supporting wheel 7, a linkage driving member 8 and a buffer spring 9.

[0038] The sliding plate 4 is connected to the upper surface of the flip wheel disc 2 in a sliding manner in the left-right direction. The sliding plate 4 provides a mounting position for other structures. The bottom plate 5 is connected to the sliding plate 4 in a vertical sliding manner. The bottom plate 5 is used to support the bottom surface of the stator 17. The side plate 6 is connected to the side of the flip wheel disc 2 in a horizontal sliding manner. There are two groups of support wheels 7. The two groups of support wheels 7 are arranged in parallel and are both connected to the right side of the side plate 6. The two groups of support wheels 7 are used to provide support for the circumferential outer side wall of the stator 17. The linkage drive member 8 is used to control the vertical sliding of the bottom plate 5 and the horizontal sliding of the side plate 6, and to make the vertical sliding of the bottom plate 5 and the horizontal sliding of the side plate 6 mutually related. The buffer spring 9 is arranged between the bottom plate 5 and the sliding plate 4.

[0039] The buffer spring 9 can play a buffering role and reduce the impact force received by the stator 17 during the process of being placed on the bottom plate 5. The bottom plate 5 cooperates with the support wheel 7 to provide support force to the circumferential side of the stator 17, so that the movement of the bottom plate 5 and the side plate 6 are interrelated, thereby buffering the change of the gravity component force of the stator 17 during the flipping process, making the component force conversion process more stable, and improving the safety of the flipping process.

[0040] Reference Figure 3 and Figure 4 Specifically, the linkage driving member 8 includes a hydraulic cylinder 1 81 , a hydraulic cylinder 2 82 , a connecting pipe 83 and a damping hole 84 .

[0041] Hydraulic cylinder 1 81 is connected to the sliding plate 4, the output end of hydraulic cylinder 1 81 is vertically upward and connected to the bottom surface of the bottom plate 5, and the buffer spring 9 is sleeved on the output end of hydraulic cylinder 1 81, which is conducive to ensuring the expansion and contraction path of the buffer spring 9 and avoiding the accidental deviation of the buffer spring 9 as much as possible. Hydraulic cylinder 2 82 is connected to the flip wheel 2, and the output end of hydraulic cylinder 2 82 extends horizontally to the right and is connected to the left side of the side plate 6. The connecting pipe 83 is arranged between hydraulic cylinder 1 81 and hydraulic cylinder 2 82, so that the hydraulic oil in hydraulic cylinder 1 81 and hydraulic cylinder 2 82 can flow along the connecting pipe 83, so that the vertical sliding of the bottom plate 5 and the lateral sliding of the side plate 6 are mutually related.

[0042] The stator 17 is placed on the bottom plate 5, the stator 17 and the bottom plate 5 gradually descend, the side plate 6 gradually extends, and the support wheel 7 abuts against the circumferential outer wall of the stator 17. In the subsequent flipping process, the support wheel 7 continues to provide support force to the stator 17, changing the previous situation where the stator 17 directly collides with the side after sliding, thereby reducing the risk of damage to the internal structure of the stator 17 as much as possible.

[0043] The damping hole 84 is disposed between the hydraulic cylinder 1 81 and the connecting pipe 83. The damping hole 84 can control the speed at which the hydraulic oil in the hydraulic cylinder 1 81 flows to the connecting pipe 83, further reducing the impact force on the stator 17.

[0044] Reference Figure 4 and Figure 5 Furthermore, a centering piece 51 is provided on the sliding plate 4, and the centering piece 51 is used to drive the bottom plate 5 so that the stator 17 on the bottom plate 5 has a tendency to be located in the middle of the sliding plate 4, which is beneficial for both sets of support wheels 7 to be connected with the circumferential outer side wall of the stator 17. If the position of the stator 17 is offset, the stator 17 may not be in normal contact with one of the support wheels 7, affecting the supporting effect and limiting effect of the device, which can improve the flexibility of the device. After the stator 17 is placed on the bottom plate 5, the position of the bottom plate 5 and the stator 17 is adjusted, and there is no need to accurately position the stator 17 when placing the stator 17, which is beneficial to improving work efficiency.

[0045] The centering member 51 includes a through hole 52, a sliding rod 53, a support block 54 and two centering springs 55. The through hole 52 vertically penetrates the middle of the sliding plate 4, the sliding rod 53 extends in the front-back direction, both ends of the sliding rod 53 are connected to the inner wall of the through hole 52, the support block 54 is sleeved on the sliding rod 53, and the support block 54 is connected to the inner wall of the through hole 52 along the axial sliding of the sliding rod 53. The hydraulic cylinder 1 81 is connected to the bottom surface of the support block 54, the output end of the hydraulic cylinder 1 81 passes upward through the inside of the support block 54 and is connected to the bottom plate 5, and a through groove for the sliding rod 53 to slide is provided on the output end of the hydraulic cylinder 1 81. The two centering springs 55 are sleeved on both ends of the sliding rod 53, one end of the centering spring 55 is connected to the inner wall of the through hole 52, and the other end of the centering spring 55 is connected to the side wall of the support block 54. The arrangement of the centering spring 55 sleeved on the sliding rod 53 can limit the telescopic path of the centering spring 55 and avoid the accidental deviation of the centering spring 55 as much as possible.

[0046] When the stator 17 is placed on the bottom plate 5, if the position of the stator 17 is offset, when the two support wheels 17 abut against the circumferential outer wall of the stator 17, the two support wheels 17 jointly push the circumferential outer wall of the stator 17, so that the stator 17 and the bottom plate 5 have a movement tendency to be located in the middle of the two support wheels 17, thereby improving the flexibility and stability of the device. A through groove is provided on the output end of the hydraulic cylinder 1 81 to provide a moving space for the sliding rod 53, so as to avoid collision between the sliding rod 53 and the output end of the hydraulic cylinder 1 81 when the output end of the hydraulic cylinder 1 81 moves up and down.

[0047] Reference Figure 6 and Figure 7 The clamping assembly includes a vertical plate 10, a support rod 11, a support wheel 12, a compression spring 13 and a control member 14.

[0048] The vertical plate 10 is slidably connected to the upper surface of the flip wheel disc 2, and the vertical plate 10 is located on the right side of the sliding plate 4. The support rod 11 extends in the left and right directions. There are two support rods 11, and the support rod 11 extends axially in the left and right directions. The two support rods 11 are arranged in parallel in the front and rear directions. The two support rods 11 are slidably inserted into the vertical plate 10, and the support wheel 12 is provided with two groups and corresponds to the two support rods 11 one by one. The support wheel 12 is connected to the left end of the support rod 11, and two compression springs 13 are provided and correspond to the two support rods 11 one by one. The compression spring 13 is sleeved on the support rod 11, and the two ends of the compression spring 13 are respectively fixedly connected to the support wheel 12 and the left side of the vertical plate 10. The compression spring 13 is sleeved on the support rod 11, and the direction of the compression spring 13 can be limited, and the situation of accidental deviation of the compression spring 13 can be avoided as much as possible, which is beneficial to the stability of the lifting device.

[0049] During the descent of the bottom plate 5, the side plate 6 extends to the right. During this process, the support wheel 1 7 pushes the stator 17. Due to the large static friction between the stator 17 and the bottom plate 5, the stator 17 moves to the right, and the bottom plate 5 and the sliding plate 4 move to the right synchronously with the stator 17 until the support wheel 2 12 abuts against the circumferential outer wall of the stator 17, thereby improving the limit of the stator 17. The support wheel 1 7, the support wheel 2 12 and the bottom plate 5 limit the stator 17 at multiple angles, which is conducive to improving the stability of the stator 17 during the flipping process and reducing the risk factor. Compared with the previous device that only supports the stator 17, it can reduce the probability of the stator 17 tilting, thereby reducing the impact force on the stator 17 and reducing the risk of damage to the internal structure of the stator 17. The compression spring 13 is set to improve the flexibility of the device, reduce the hard contact between the device and the stator 17, thereby reducing the impact force, and facilitate leaving operating space for other structures, so that the stator 17 can still move to the right a distance after contacting the support wheel 2 12, which is convenient for the installation and normal operation of the structure.

[0050] Reference Figure 7 Furthermore, two tension springs 41 are provided at the right end of the sliding plate 4. The tension springs 41 extend in the left-right direction. The tension springs 41 are provided inside the flip wheel 2. The right end of the tension springs 41 is fixedly connected to the flip wheel 2, and the left end of the tension springs 41 is fixedly connected to the right side of the sliding plate 4. When the sliding plate 4 moves to the left, the tension springs 41 are stretched, and the tension springs 41 apply a rightward tension to the sliding plate 4, so that the sliding plate 4 has a tendency to move to the right. The sliding plate 4 can be reset under the action of the tension springs 41, and there is no need to manually reset the sliding plate 4 to the right, which can improve the automation of the device, facilitate repeated use of the device, and improve the convenience of the device.

[0051] Reference Figure 6 and Figure 7 The control member 14 is arranged between the sliding plate 4 and the vertical plate 10, and is used to make the supporting wheel 2 12 always hold the circumferential outer wall of the stator 17 during the flipping process of the stator 17, to ensure the stable positioning of the stator 17 by the device, so as to reduce the occurrence of accidental tilting of the stator 17 during the flipping process, improve the stability of the device, and increase the safety factor.

[0052] The control member 14 includes a double-headed cylinder 141 , a first stopper 142 , a second stopper 143 and a return spring 144 .

[0053] The double-headed cylinder 141 is connected to the right side of the sliding plate 4. The two output ends of the double-headed cylinder 141 face the front side and the rear side respectively. There are two stoppers 142, which correspond to the two output ends one by one. The stoppers 142 are fixedly connected to the output ends. When the double-headed cylinder 141 is started, the two output ends extend or retract synchronously, thereby controlling the two stoppers 142 to extend or retract synchronously. There are two stoppers 143, which are both arranged at the bottom of the vertical plate 10. The stoppers 143 are connected to the flip wheel 2 in a sliding manner in the left-right direction. The two stoppers 142 correspond to the two stoppers 143 one by one. The stoppers 142 can abut against the stoppers 143. There are two return springs 144, which are arranged in parallel in the front-to-back direction, and extend in the left-to-right direction. The return spring 144 is arranged between the left side of the second block 143 and the flip wheel 2. After the second block 143 and the first block 142 move to the left synchronously, the return spring 144 is stretched, and the return spring 144 applies a pulling force to the right on the second block 143, so that the second block 143 has a movement tendency to move to the right.

[0054] The sliding plate 4 moves to the right, and the double-headed cylinder 141 controls the two blocks 142 to retract synchronously. The sliding plate 4 continues to move to the right, and the double-headed cylinder 141 and the block 142 move rightward to the right side of the block 2 143. The double-headed cylinder 141 controls the two blocks 142 to extend synchronously, and the left side of the block 142 abuts against the right side of the block 2 143, so that when the subsequent sliding plate 4 moves to the left, the block 142 pushes the block 2 143, and then the vertical plate 10, the supporting wheel 2 12 and the sliding plate 4 move synchronously to the left, which is convenient for controlling the synchronous movement. A reset spring 144 is provided to facilitate the reset of the block 2 143, and there is no need to manually reset the block 2 143, which improves the automation of the device and facilitates the repeated use of the device.

[0055] Furthermore, in other embodiments, the control member 14 may also adopt a structure such as a hydraulic cylinder output end directly controlling the left and right movement of the vertical plate 10, so that the vertical plate 10 and the sliding plate 4 can be moved synchronously in the front stage of the flipping process, and the limiting effect of the supporting wheel 2 12 on the stator 17 can be maintained. In this embodiment, the control is carried out by means of a double-headed cylinder 141, a stopper 1 142 and a stopper 2 143, which is conducive to making the vertical plate 10 and the sliding plate 4 move synchronously or stop synchronously.

[0056] Reference Figure 6 and Figure 7 Furthermore, a rotating member 15 is provided on the flip wheel 2, and the rotating member 15 is used to control the vertical plate 10 to rotate relative to the flip wheel 2. The state of the vertical plate 10 is controlled so that the vertical plate 10 and the supporting wheel 2 12 can provide support and limit the stator 17, and the vertical plate 10 can also make room for other processes.

[0057] The rotating member 15 includes a rotating motor. The rotating motor is fixedly connected to one of the second stoppers 143, and the output end of the rotating motor extends in the front-rear direction. The output end of the rotating motor is rotatably connected to the top of one of the second stoppers 143, and the bottom of the vertical plate 10 is rotatably connected to the tops of the two second stoppers 143, and the output end of the rotating motor is fixedly connected to the bottom of the vertical plate 10.

[0058] Start the rotating motor, the output end of the rotating motor rotates, and drives the vertical plate 10 to rotate. This is beneficial to free up operating space and facilitate the processing and operation of the stator 17. When the vertical plate 10 and the second stopper 143 move left and right following the sliding plate 4, the rotating motor and the second stopper 143 move synchronously to ensure the normal operation of the device.

[0059] Reference Figure 1 and Figure 2 Further, an anti-dropping block 16 is provided on the side of the flip wheel 2, which is located above the side plate 6 and can abut against the stator 17. The anti-dropping block 16 is detachably connected to the flip wheel 2 by bolts. It is beneficial to the stability and flexibility of the lifting device.

[0060] The implementation principle of a motor stator flipping device according to an embodiment of the present invention is as follows: The stator 17 is placed on the bottom plate 5 by an external lifting device. The buffer spring 9 plays a buffering role to reduce the impact force on the stator 17. Under the gravity of the stator 17, the stator 17 and the bottom plate 5 move downward, the output end of the hydraulic cylinder 1 81 retracts, the output end of the hydraulic cylinder 2 82 extends, and the side plate 6 moves rightward until the two support wheels 1 7 abut against the circumferential outer wall of the stator 17. The rotating member 15 controls the vertical plate 10 to put the vertical plate 10 in a vertical placement state. The side plate 6 continues to move rightward, pushing the stator 17, the bottom plate 5 and the movable plate to move rightward together until the support wheel 2 12 abuts against the circumferential outer wall of the stator 17. In the process of the support wheel 1 7 and the support wheel 2 12 abutting against the stator 17 successively, the stator 17 and the bottom plate 5 tend to be located in the middle of the sliding rod 53 due to the pushing effect of the two support wheels 1 7 and the two support wheels 2 12. As the side plate 6 continues to move right, the double-headed cylinder 141 controls the two stoppers 142 to retract, the side plate 6 moves to the right, and the stopper 142 moves to the right side of the stopper 2 143. The double-headed cylinder 141 controls the two stoppers 142 to extend, and the stopper 142 abuts against the right side of the stopper 2 143.

[0061] The driving shaft 31 is driven to rotate by an external rotating driving element, so that the flip wheel 2 rotates to flip the stator 17. During the flipping process, the support wheel 1 7, the support wheel 2 12 and the bottom plate 5 cooperate to limit the position of the stator 17.

[0062] In the front part of the flipping process, the stator 17 exerts a relatively large pressure on the bottom plate 5, and the static friction between the two is large. During the flipping process of the stator 17, the output end of the hydraulic cylinder 1 81 extends, the output end of the hydraulic cylinder 2 82 retracts, the bottom plate 5 extends, and the side plate 6 and the support wheel 1 7 retract. Under the action of the static friction of the stator 17, the sliding plate 4 and the bottom plate 5 are close to the side plate 6, and the support wheel 1 7 and the support wheel 2 12 limit the position of the stator 17, thereby improving the stability of the flipping process.

[0063] Until the rear end of the flipping process, the supporting force of the support wheel 7 on the stator 17 is large, the pressure of the stator 17 on the bottom plate 5 is reduced, the stator 17 and the bottom plate 5 slide relative to each other, the support wheel 7 continues to provide supporting force to the stator 17, the support wheel 7 and the side plate 6 retract, the bottom plate 5 extends, and the extended bottom plate 5 pushes the stator 17, causing the stator 17 to slide along the two support wheels 7.

[0064] After the turning is completed, the vertical plate 10 is rotated by the control of the rotating member 15 to make room for operation. The stator 17 is processed and then removed by an external lifting device.

[0065] The flip wheel 2 is reset. The double-headed cylinder 141 controls the two stoppers 142 to retract, the sliding plate 4 is reset under the action of the tension spring 41, and the stopper 2 143 is reset under the action of the reset spring 144. It is convenient for next use.

[0066] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0067] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
