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, in order to facilitate subsequent assembly or inspection work, it is necessary to flip the stator.

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

[0004] For the above-mentioned related technologies, limited by the accuracy of the stator movement process, when the stator is placed on the upper surface of the flipping wheel disc, there may be a gap between the circumferential outer wall of the stator and the side surface of the flipping wheel disc. During the flipping process of the stator, as the inclination angle changes, the supporting force of the upper surface of the flipping wheel disc on the stator also changes. When a certain angle is reached, the stator slides relative to the upper surface, and the stator moves towards the side and impacts the side. This impact may cause damage to the internal structure of the stator, posing a safety hazard; and during the flipping process of the stator, the component force of the stator gravity is continuously transformed and acts on the flipping device. Due to a certain rotational error in the motor speed, the transformation process of the component force is unstable. When the transformation 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 a large impact force during the flipping process and the flipping process is unstable, which easily causes damage to the stator and the flipping device.

[0006] To solve the above technical problems, a motor stator flipping device provided by the present invention adopts the following technical solutions: A motor stator flipping device includes a flipping machine base, a flipping wheel disc, and a flipping driving member;

[0007] A sliding plate slidably connected to the upper surface of the flipping wheel disc in the left-right direction, a bottom plate vertically slidably connected to the sliding plate, a side plate horizontally slidably connected to the side surface of the flipping wheel disc, and two sets of supporting wheels I capable of abutting against the circumferential outer wall of the stator are provided on the side plate;

[0008] 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;

[0009] 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.

[0010] 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.

[0011] 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.

[0012] 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.

[0013] 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.

[0014] 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;

[0015] 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.

[0016] 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.

[0017] Optionally, the flip wheel is provided with a rotating member capable of controlling the vertical plate to rotate relative to the flip wheel.

[0018] 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.

[0019] Optionally, the rotating member includes a rotating motor connected to the stopper 2, the output end of the rotating motor is rotatably connected to the top of one of the stoppers 2, the bottom of the vertical plate is rotatably connected to the tops of the two stoppers 2, and the output end of the rotating motor is fixedly connected to the bottom of the vertical plate.

[0020] By adopting the above technical solution, it is convenient to control the rotation of the vertical plate.

[0021] Optionally, the hydraulic cylinder 1 is connected to the connecting pipe via a damping hole.

[0022] The adoption of the technical solution is helpful to buffer the falling process and the turning process of the stator.

[0023] 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.

[0024] The adoption of the above technical solution is helpful to improve the stability of the device.

[0025] Optionally, the anti-drop block is detachably connected to the flip wheel disc via bolts.

[0026] By adopting the above technical solution, the flexibility of the device is improved.

[0027] 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.

[0028] By adopting the above technical solution, the sliding plate is easy to reset, which is conducive to the repeated use of the device.

[0029] 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.

[0030] 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.

Detailed implementation manners

[0044] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention fall within the scope of protection of the present invention.

[0045] The following will further describe the present invention in detail with reference to the attached Figure 1 - attached Figure 7 for further detailed description of the present invention.

[0046] The embodiment of the present invention discloses a motor stator turnover device. Referring to Figures 1 to 7 , a motor stator turnover device includes a turnover machine base 1, a turnover wheel disc 2, a turnover driving member 3, a buffer assembly and a clamping assembly.

[0047] Referring to Figure 1 and Figure 2, the base 1 of the turnover machine is placed on a horizontal ground, and an open mouth for the rotation of the turnover wheel disc 2 is provided on the top surface of the base 1 of the turnover machine. The turnover driving member 3 is arranged between the base 1 of the turnover machine and the turnover wheel disc 2 and is used to drive the turnover wheel disc 2 to rotate. Specifically, the turnover driving member 3 includes a driving shaft 31, gears 32, racks 33 and rotating wheels 34. The driving shaft 31 is rotatably connected to the inside of the base 1 of the turnover machine. There are two gears 32, and the two gears 32 are respectively connected to both ends of the driving shaft 31. The racks 33 are connected to the circumferential outer side wall of the turnover wheel disc 2, and the racks 33 are engaged with the gears 32. Among them, there are two racks 33, and the two racks 33 are arranged in parallel. For the sake of clarity of the illustration, only one rack 33 is drawn in the illustration. There are four rotating wheels 34, which are arranged in a rectangle inside the base 1 of the turnover machine, and the rotating wheels 34 are in contact with the circumferential outer side wall of the turnover wheel disc 2.

[0048] By connecting an external rotating driving element, such as a rotating motor, to drive the driving shaft 31 to rotate, the gears 32 rotate synchronously with the driving shaft 31. The gears 32 drive the racks 33 to make the turnover wheel disc 2 rotate. The rotating wheels 34 play a supporting role, which is beneficial to the stable rotation of the turnover wheel disc 2. In this embodiment, the cooperation of the gears 32 and the racks 33 can achieve precise position control, can bear a large load, is beneficial to provide a smooth force transmission, reduce impact and vibration, and is flexible to install. Further, in other embodiments, the turnover driving member 3 can also drive the turnover wheel disc 2 to rotate in other ways, and only an example is given here.

[0049] Refer to Figure 3 and Figure 4 , the buffer assembly includes a sliding plate 4, a bottom plate 5, side plates 6, a first support wheel 7, a linkage driving member 8 and a buffer spring 9.

[0050] The sliding plate 4 is slidably connected to the upper surface of the turnover wheel disc 2 in the left-right direction. The sliding plate 4 provides an installation position for other structures. The bottom plate 5 is slidably connected to the sliding plate 4 vertically. The bottom plate 5 is used to support the bottom surface of the stator 17. The side plates 6 are slidably connected to the side surface of the turnover wheel disc 2 horizontally. There are two groups of the first support wheels 7, and the two groups of the first support wheels 7 are arranged in parallel and are both connected to the right side surface of the side plates 6. The two groups of the first support wheels 7 are used to provide support for the circumferential outer side wall of the stator 17. The linkage driving member 8 is used to control the vertical sliding of the bottom plate 5 and the horizontal sliding of the side plates 6, and make the vertical sliding of the bottom plate 5 and the horizontal sliding of the side plates 6 related to each other. The buffer spring 9 is arranged between the bottom plate 5 and the sliding plate 4.

[0051] 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.

[0052] 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 .

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] During the downward movement of the bottom plate 5, the side plate 6 extends to the right. During this process, the first support wheel 7 pushes against 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 second support wheel 12 abuts against the circumferential outer wall of the stator 17 to complete the limiting of the stator 17. The first support wheel 7, the second support wheel 12, and the bottom plate 5 limit the stator 17 from multiple angles, which is beneficial to improving the stability of the stator 17 during the flipping process, reducing the risk coefficient. Compared with the previous device that provides single support for the stator 17, it can reduce the probability of the stator 17 tilting, thereby reducing the impact force on the stator 17 and the risk of damage to the internal structure of the stator 17 due to impact. The compression spring 13 is provided to improve the flexibility of the device, reduce the hard contact between the device and the stator 17, thereby reducing the impact force, and facilitating leaving an operating space for other structures, so that the stator 17 can still move to the right for a certain distance after contacting the second support wheel 12, which is convenient for the installation and normal operation of the structure.

[0062] Refer to Figure 7 , Further, 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 arranged inside the flipping wheel disc 2. The right ends of the tension springs 41 are fixedly connected to the flipping wheel disc 2, and the left ends of the tension springs 41 are fixedly connected to the right side of the sliding plate 4. After the sliding plate 4 moves to the left, the tension springs 41 are stretched. The tension springs 41 apply a pulling force to the right on the sliding plate 4, giving the sliding plate 4 a tendency to move to the right. This enables the sliding plate 4 to be reset under the action of the tension springs 41 without manually moving the sliding plate 4 to the right for reset, which can improve the automation degree of the device, facilitate the repeated use of the device, and improve the convenience of the device.

[0063] Refer to 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 keep the second support wheel 12 tightly holding the circumferential outer wall of the stator 17 during the flipping process of the stator 17, ensuring the stable limiting of the stator 17 by the device, reducing the occurrence of accidental tilting of the stator 17 during the flipping process, improving the stability of the device, and increasing the safety factor.

[0064] The control member 14 includes a double-headed cylinder 141, a first stop block 142, a second stop block 143, and a return spring 144.

[0065] 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 first stoppers 142, which correspond to the two output ends one by one. The first stopper 142 is fixedly connected to the output end. When the double-headed cylinder 141 is started, the two output ends extend or retract synchronously, and then control the two first stoppers 142 to extend or retract synchronously. There are two second stoppers 143, which are both arranged at the bottom of the vertical plate 10. The second stopper 143 is slidably connected to the flipping wheel disc 2 in the left-right direction. The two first stoppers 142 correspond to the two second stoppers 143 one by one, and the first stopper 142 can abut against the second stopper 143. There are two return springs 144. The two return springs 144 are arranged in parallel in the front-rear direction. The return spring 144 extends in the left-right direction. The return spring 144 is arranged between the left side of the second stopper 143 and the flipping wheel disc 2. After the second stopper 143 and the first stopper 142 move left synchronously, the return spring 144 is stretched, and the return spring 144 exerts a pulling force in the right direction on the second stopper 143, so that the second stopper 143 has a tendency to move right.

[0066] When the sliding plate 4 moves right, the double-headed cylinder 141 controls the two first stoppers 142 to retract synchronously. When the sliding plate 4 continues to move right, the double-headed cylinder 141 and the first stopper 142 move right to the right side of the second stopper 143. The double-headed cylinder 141 controls the two first stoppers 142 to extend synchronously. The left side of the first stopper 142 abuts against the right side of the second stopper 143. When the subsequent sliding plate 4 moves left, the first stopper 142 pushes the second stopper 143, and then the vertical plate 10, the second supporting wheel 12 and the sliding plate 4 move left synchronously, which is convenient for controlling the actual synchronous movement. The return spring 144 is set to facilitate the reset of the second stopper 143, without manually resetting the second stopper 143 by hand, improving the automation degree of the device and facilitating the multiple use of the device.

[0067] Further, in other embodiments, the control member 14 can also adopt a structure in which the output end of the hydraulic cylinder directly controls the left-right movement of the vertical plate 10, etc. In the first stage of the flipping process, the vertical plate 10 and the sliding plate 4 move synchronously to maintain the limiting effect of the second supporting wheel 12 on the stator 17. In this embodiment, the control is carried out through the double-headed cylinder 141, the first stopper 142 and the second stopper 143, which is beneficial to the synchronous movement or synchronous stillness of the vertical plate 10 and the sliding plate 4.

[0068] Refer to Figure 6 and Figure 7 , further, a rotating member 15 is provided on the flipping wheel disc 2. The rotating member 15 is used to control the rotation of the vertical plate 10 relative to the flipping wheel disc 2. The state of the vertical plate 10 is controlled so that the vertical plate 10 and the second supporting wheel 12 can provide support and limitation for the stator 17, and the vertical plate 10 can also make room for other processes.

[0069] The rotating member 15 includes a rotating motor. The rotating motor is fixedly connected to one of the second stoppers 143. The output end of the rotating motor extends in the front-rear direction. The output end of the rotating motor penetrates through the top of one of the second stoppers 143 in a rotatable connection manner. The bottom of the vertical plate 10 is rotatably connected to the tops of the two second stoppers 143. The output end of the rotating motor penetrates through the bottom of the vertical plate 10 in a fixed connection manner.

[0070] Start the rotating motor. The output end of the rotating motor rotates, driving the vertical plate 10 to rotate. This is beneficial for creating an operating space and facilitating 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 moves synchronously with the second stopper 143 to ensure the normal operation of the device.

[0071] Refer to Figure 1 and Figure 2 As shown in, further, an anti - detachment block 16 is provided on the side of the flipping wheel disc 2 above the side plate 6 and capable of abutting against the stator 17. The anti - detachment block 16 is detachably connected to the flipping wheel disc 2 by bolts. This is beneficial for improving the stability and flexibility of the device.

[0072] The implementation principle of a motor stator flipping device according to an embodiment of the present invention is as follows:

[0073] The stator 17 is placed on the bottom plate 5 through an external hoisting device. The buffer spring 9 plays a buffering role, reducing the impact force received by the stator 17. Under the action of the gravity of the stator 17, the stator 17 and the bottom plate 5 move downward. The output end of the first hydraulic cylinder 81 retracts, and the output end of the second hydraulic cylinder 82 extends. The side plate 6 moves to the right until the two first support wheels 7 abut against the circumferential outer wall of the stator 17. The rotating member 15 controls the vertical plate 10 to make the vertical plate 10 in a vertically placed state. The side plate 6 continues to move to the right, pushing the stator 17, the bottom plate 5 and the moving plate to move to the right together until the second support wheels 12 abut against the circumferential outer wall of the stator 17. During the process where the first support wheels 7 and the second support wheels 12 successively abut against the stator 17, under the pushing action of the two first support wheels 7 and the two second support wheels 12, the stator 17 and the bottom plate 5 tend to be located in the middle of the sliding rod 53. During the process where the side plate 6 continues to move to the right, the double - headed cylinder 141 controls the two first stoppers 142 to retract. The side plate 6 moves to the right, and the first stopper 142 moves to the right side of the second stopper 143. The double - headed cylinder 141 controls the two first stoppers 142 to extend, and the first stopper 142 abuts against the right side of the second stopper 143.

[0074] Drive the drive shaft 31 to rotate through an external rotation drive element, causing the flipping wheel disc 2 to rotate and flip the stator 17. During the flipping process, the first support wheels 7, the second support wheels 12 and the bottom plate 5 cooperate to limit the position of the stator 17.

[0075] In the first stage of the flipping process, the stator 17 exerts a relatively large pressure on the bottom plate 5, and the static friction force between the two is large. During the flipping process of the stator 17, the output end of the first hydraulic cylinder 81 extends, the output end of the second hydraulic cylinder 82 retracts, the bottom plate 5 extends, the side plate 6 and the first support wheel 7 retract. Under the action of the static friction force of the stator 17, the sliding plate 4 approaches the side plate 6 of the bottom plate 5. The first support wheel 7 and the second support wheel 12 limit the position of the stator 17, improving the stability of the flipping process.

[0076] Until the end stage of the flipping process, at this time, the supporting force of the first support wheel 7 on the stator 17 is large, the pressure of the stator 17 on the bottom plate 5 decreases, and relative sliding occurs between the stator 17 and the bottom plate 5. The first support wheel 7 continuously provides a supporting force for the stator 17. The first support wheel 7 and the side plate 6 retract, and the bottom plate 5 extends. The extended bottom plate 5 pushes the stator 17, causing the stator 17 to slide along the two first support wheels 7.

[0077] After the flipping is completed, it is controlled by the rotating member 15 to rotate the vertical plate 10 to create an operating space. The stator 17 is processed, and after processing, the stator 17 is taken away by an external hoisting device.

[0078] The flipping wheel disc 2 is reset. The double-headed cylinder 141 controls the two first stoppers 142 to retract. The sliding plate 4 is reset under the action of the tension spring 41, and the second stopper 143 is reset under the action of the return spring 144. It is convenient for the next use.

[0079] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" 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 directly connected or indirectly connected through an intermediate medium, and it can be the communication inside 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 situations.

[0080] The above is the preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle described in the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
