The flipping mechanism integrates a conveying device, a lifting device, a flipping device and a flexible clamping device to achieve fully automated operation from conveying, clamping to flipping of the operating mechanism to be flipped, reducing manual intervention, improving production efficiency, and reducing the risk of errors or safety accidents caused by improper human operation.

[0029] In addition, the design of the flexible clamping device, combined with the buffer device, can provide appropriate pressure and buffering when clamping the operating mechanism, avoiding damage to the mechanism, while also ensuring stability during the flipping process and reducing positioning deviations caused by vibration or impact.

[0030] 2. There are three groups of clamping blocks, which can move freely laterally on the guide shaft under the action of the clamping piston to realize the clamping operation of the mechanism. There is no need to limit the mechanism and there is no strict requirement for the initial position of the mechanism. At the same time, the initial spacing of the clamping blocks is large, which can achieve clamping of mechanisms of various sizes and has a wide applicability.

[0031] 3. By installing the connection between the bent plate and the tail flange, a stable support point is provided for the clamping cylinder, ensuring the stability of the clamping cylinder during operation and effectively preventing the clamping cylinder from deflecting due to uneven force or vibration, thereby improving the accuracy and reliability of the clamping operation.

The cooperation between the two first sliding bearing bases and the guide shaft limits the lateral deviation of the flipping mechanism during the flipping process, making the flipping action more stable and reliable. Secondly, the first sliding bearing base serves as the support point of the guide shaft and has a strong load-bearing capacity.

[0034] 6. The lifting piston rod is set in the lifting cylinder. The piston rod is extended and retracted through the driving force of the cylinder, thereby driving the square tube to lift, ensuring the stability and controllability of the lifting process and avoiding the impact caused by sudden start or stop.

[0035] 7. The buffer spring installed outside the second sliding bearing base can absorb and disperse energy when it is impacted or vibrated, playing a role in buffering and shock absorption, helping to protect the clamping device and operating mechanism from damage caused by instantaneous impact force and prolong the service life of the equipment.

[0036] 8. The combination of washers and nuts can accurately locate the position of the buffer spring on the guide pin. By adjusting the tightness of the nut, it can be ensured that the position of the buffer spring remains relatively stable when it is compressed or stretched, and will not deviate or slide.

[0037] 9. The sliding pair formed by the guide pin and the base provides a stable guide and sliding path for the sliding arm. During the operation of the buffer device, the sliding arm can slide smoothly along the sliding pair formed by the guide pin and the base, ensuring the accuracy and stability of the buffer action.

DETAILED DESCRIPTION

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0045] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0046] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0047] In the description of the embodiments of the present invention, it should be noted that if the terms "upper," "lower," "horizontal," "inner," etc. appear, the orientation or positional relationship indicated is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the inventive product is typically placed when in use. These terms are merely for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first," "second," etc. are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0048] In addition, if the term "horizontal" appears, it does not mean that the component must be absolutely horizontal, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0049] During the final assembly of a high-voltage switch operating mechanism, the mechanism must be flipped 180 degrees and a sealing strip applied. This process is currently primarily performed manually, using lifting equipment to hoist the operating mechanism and then manually flipping it. Due to the heavy weight of the operating mechanism, manual flipping is very inconvenient, taking approximately ten minutes for a single mechanism. Furthermore, manual operation presents technical challenges such as high risk and low efficiency.

[0050] In order to solve the above technical defects, the inventor provides an automated high-voltage switch operating mechanism clamping and flipping device and method.

[0051] The present invention is described in further detail below with reference to the accompanying drawings:

[0052] like Figure 1-Figure 3As shown, an embodiment of the present invention, in a first aspect, provides an automated high-voltage switch operating mechanism clamping and flipping mechanism, comprising: a load device, on which a conveying device is provided; a lifting device, one end of which is connected to the load device and the other end of which is connected to a flipping device; a flexible clamping device, which is connected to the flipping device and has a buffer device on the flexible clamping device; and a control device, which is electrically connected to the conveying device, the lifting device, the flipping device, and the flexible clamping device. The conveying device is used to convey the operating mechanism to be flipped onto the load device, and the flipping device, the flexible clamping device, and the buffer device cooperate to clamp and flip the operating mechanism to be flipped. By integrating the conveying device, the lifting device, the flipping device, and the flexible clamping device, the mechanism achieves fully automated operation from conveying, clamping, to flipping the operating mechanism to be flipped, which greatly reduces manual intervention, improves production efficiency, and reduces the risk of errors or safety accidents caused by improper human operation. Furthermore, the design of the flexible clamping device, in conjunction with the buffer device, can provide appropriate pressure and buffering when clamping the operating mechanism, avoiding damage to the mechanism, ensuring stability during the flipping process, and reducing positioning deviations caused by vibration or impact. In addition, automated operation reduces the impact of human factors on product quality, such as uneven operating force and inaccurate positioning. In addition, by precisely controlling the flip angle and speed, the mechanism can ensure that the operating mechanism remains in the best condition during the flipping process, thereby improving the overall quality and reliability of the product. Due to the improvement in production efficiency and product quality, the production cost and maintenance cost are also reduced accordingly. The mechanism has a certain degree of versatility and can adapt to operating mechanisms of different models or sizes by adjusting the control program or replacing some components. This flexibility and adaptability enable the mechanism to be widely used in the production and maintenance of various high-voltage switches. Figure 1As shown, the conveying device includes a pallet 3 and a rotary disc 2 mounted on the pallet 3, and the pallet 3 is mounted on the top of the load device; the flexible clamping device includes a clamping block 4, a fixed seat 5, a fixed seat mounting plate 6, a first side plate 7, a cylinder mounting plate 13, a mounting bent plate 14, a tail end flange 15, a second side plate 16, a first sliding bearing base 17, a rod end flange 28, a clamping cylinder 27, a piston rod 31 and a guide shaft 32, and the first side plate 7 and the second side plate 16 are both mounted with a fixed seat mounting plate 6, and the fixed seat mounting plate 6 is mounted with a fixed seat 5 and a clamping block 4, and three groups of clamping blocks 4 are provided. In the above structure, the combination design of the pallet 3 and the rotary disc 2 enables the operating mechanism to be flipped to be stably placed on the pallet 3, and to be accurately positioned and conveyed by the rotary disc 2, ensuring that the operating mechanism will not deviate or slip during the conveying process, thereby improving the accuracy and stability of the conveying, and being able to continuously and efficiently convey the operating mechanism to be flipped, reducing manual handling and waiting time, thereby improving overall production efficiency. The coordination of the clamping module, consisting of three groups of clamping blocks 4 and a fixed seat 5, a fixed seat mounting plate 6, a first side plate 7, a second side plate 16, a cylinder mounting plate 13, a rod end flange 28, a clamping cylinder 27, a fixed seat 5, a fixed seat mounting plate 6, a clamping block 4, and a piston rod 31, achieves stable clamping of the flip operating mechanism. This multi-point clamping method can evenly distribute the clamping force, avoiding local damage to the operating mechanism. In addition, the cylinder mounting plate 13 and the mounting bend plate 14 enable the clamping device to flexibly adjust the clamping position and angle according to actual needs, thereby improving the flexibility and accuracy of the operation. The clamping cylinder 27 drives the clamping block 4 to perform the clamping operation via the piston rod 31, achieving automated control, reducing manual intervention, and improving the accuracy and efficiency of the operation. The coordination of the guide shaft 32 and the rod end flange 28 not only provides a stable guide for the clamping operation, but also plays a buffering and protective role to a certain extent, reducing the impact and vibration during the clamping process.

[0053] In this embodiment, the first side plate 7 is fixedly connected to the clamping cylinder 27 via the installation bent plate 14 and the tail flange 15, providing a stable support point for the clamping cylinder 27, ensuring the stability of the clamping cylinder 27 during operation, and effectively preventing the clamping cylinder 27 from deflecting due to uneven force or vibration, thereby improving the accuracy and reliability of the clamping operation. The installation bent plate 14 and the tail flange 15 serve as connectors, making the connection between the clamping cylinder 27 and the first side plate 7 more flexible and adjustable. During equipment installation or commissioning, the position and angle of these connectors can be adjusted to optimize the working position and clamping force of the clamping cylinder 27, thereby meeting the clamping requirements of operating mechanisms of different models or sizes. Since the clamping cylinder 27 is connected to the first side plate 7 via the installation bent plate 14 and the tail flange 15, when the clamping cylinder 27 needs to be repaired or replaced, it can be easily disassembled and reinstalled, reducing maintenance difficulty and cost.

[0054] In this embodiment, a piston rod 31 is mounted within the clamping cylinder 27. The other end of the piston rod 31 is fixed to the second side plate 16. The piston rod 31 directly connects the clamping cylinder 27 and the second side plate 16, achieving direct force transmission and eliminating intermediate transmission links. This makes the clamping action more rapid and sensitive, helping to shorten clamping time and improve production efficiency. The direct connection between the piston rod 31 and the second side plate 16 makes the structure of the clamping device more compact, reducing unnecessary space occupation. Furthermore, the fixed connection between the piston rod 31 and the second side plate 16 is typically achieved through a simple threaded connection or pin connection, which facilitates disassembly and replacement. When the clamping device requires repair or maintenance, the piston rod 31 and the second side plate 16 can be quickly removed, reducing maintenance difficulty and cost.

[0055] A guide shaft 32 is mounted on the flipping device. A stop nut 33 is installed on one side of the guide shaft 32. A first stop pin 34 is mounted on the stop nut 33. A polyurethane pad 35 is attached to one side of the first stop pin 34. A first sliding bearing base 17 is mounted on the guide shaft 32. Two first sliding bearing bases 17 are provided: one is connected to the first side plate 7, and the other is connected to the second side plate 16. The guide shaft 32 provides stable guidance for the flipping device, ensuring smooth and accurate flipping. The two first sliding bearing bases 17 work together with the guide shaft 32 to limit lateral deviation during flipping, ensuring a more stable and reliable flipping motion. The first sliding bearing bases 17, serving as support points for the guide shaft 32, have a strong load-bearing capacity. The two first sliding bearing bases 17 are connected to the first side plate 7 and the second side plate 16, respectively, distributing the load generated during flipping and improving the load-bearing capacity of the entire flipping device.

[0056] A sliding bearing or lubrication device is usually provided inside the first sliding bearing base 17, which can reduce the friction and wear between the guide shaft 32 and the first sliding bearing base 17, extend the service life of the guide shaft 32 and the first sliding bearing base 17, and reduce the maintenance cost of the equipment; and, through the cooperation of the guide shaft 32 and the first sliding bearing base 17, the flipping angle and speed of the flipping device can be accurately controlled, thereby improving the accuracy and controllability of the flipping and helping to meet different production needs. Finally, the connection between the guide shaft 32 and the two first sliding bearing bases 17 forms a stable triangular structure, which enhances the structural rigidity of the flipping device, making it less likely for the flipping device to be deformed or damaged when subjected to a large load, thereby improving the stability and durability of the equipment. Figure 1As shown, the flipping device includes a speed reducer 24, a first shaft 37, a first operating arm 18, a second operating arm 36, and a rolling bearing 39. A mounting plate 40 is mounted on one side of the rolling bearing 39, and a micro switch 41 is mounted on one side of the mounting plate 40. The speed reducer 24 is provided with a lifting device, and the drive end of the speed reducer 24 is connected to the first shaft 37, on which the first operating arm 18 and the second operating arm 36 are mounted. As a power source, the speed reducer 24 can provide a stable and adjustable driving force. Through the speed reducer 24, the flipping speed and flipping torque can be precisely controlled to meet the requirements of different working conditions. The first shaft 37, as the main transmission component of the flipping device, connects the speed reducer 24 and the first operating arm 18 and the second operating arm 36, achieving power transmission. The first operating arm 18 and the second operating arm 36 are mounted on the first shaft 37 and can flip as the first shaft 37 rotates, thereby achieving precise control of the flipped object and reducing friction and wear. The introduction of rolling bearing 39 effectively reduces friction and wear during the flipping process. Rolling bearing 39 can withstand large radial and axial loads while maintaining a low coefficient of friction, thereby extending the service life of the flipping device. A first spring 25 is mounted on the second stop pin 26, and the rod end flange 28 is mounted on the clamping cylinder 27. The rolling bearing 39 also has excellent self-rotation performance, helping to reduce energy loss during the flipping process and improve flipping efficiency. Through the coordinated action of the reducer 24, first shaft 37, first operating arm 18, and second operating arm 36, the flipping device can efficiently complete the flipping operation of an object, improving work efficiency. Furthermore, because the motion trajectory and force conditions of each component during the flipping process are precisely controlled, operational safety is improved, reducing the possibility of accidents.

[0057] In this embodiment, the lifting device includes a bearing seat 38, a square tube 42, a third sliding bearing base 43, a second shaft 44, a lifting piston rod 46, and a lifting cylinder 47. The lifting piston rod 46 is disposed within the lifting cylinder 47, with the end of the lifting piston rod 46 connected to the square tube 42. The bearing seat 38 and the second shaft 44 are mounted on the square tube 42, and the second shaft 44 passes through the third sliding bearing base 43. The lifting cylinder 47 serves as a power source, transmitting the lifting force through the lifting piston rod 46, thereby providing a continuous and controllable lifting force and ensuring a smooth lifting process. The direct connection between the lifting piston rod 46 and the square tube 42 reduces losses during force transmission and improves lifting efficiency. The square tube 42, as the primary supporting structure of the lifting device, has sufficient strength and rigidity to withstand the various forces and moments during the lifting process. The installation of the bearing seat 38 and the second shaft 44 provides stable support and guidance for the square tube 42, ensuring stability and accuracy during the lifting process. The second shaft 44 passes through the third sliding bearing base 43, reducing friction and wear and improving the durability of the lifting device.

[0058] In this embodiment, the buffer device includes a support plate protective pad 8, a support plate 9, a sliding arm 10, a first guide pin 11, a base 12, a second sliding bearing base 19, a buffer spring 20, a second guide pin 21, a washer 22, a nut 23, a second spring 29, and a retaining sleeve 30. The second sliding bearing base 19 is fixed to the fixed base mounting plate 6 of the clamping device. The buffer spring 20 is mounted on the outer surface of the second sliding bearing base 19, and the second guide pin 21 is inserted into the inner surface of the second sliding bearing base 19. The buffer spring 20 is mounted on the outer surface of the second sliding bearing base 19. When subjected to external impact or vibration, the buffer spring 20 can absorb and dissipate this energy, thereby providing an effective buffering effect, helping to protect the clamping device and the tilting mechanism it clamps from damage and extending the service life of the device. The second guide pin 21, which passes through the second sliding bearing base 19, provides a stable guide for the sliding arm 10, ensuring stability and accuracy during movement and preventing errors caused by deviation or shaking. At the same time, the second sliding bearing base 19 serves as a support point, providing a solid support for the entire buffer device and enhancing the rigidity and stability of the device; the coordinated use of the nut 23 and the washer 22 allows the preload force of the buffer spring 20 to be easily adjusted, and the buffering effect of the buffer device can be adjusted according to actual needs, thereby improving the flexibility and adaptability of the device.

[0059] A washer 22 and a nut 23 are attached to one end of the second guide pin 21. These two components are used to restrict the position of the buffer spring 20. Their combined use allows for precise control of the compression and extension of the buffer spring 20. Adjusting the tightening of the nut 23 changes the preload of the buffer spring 20, enabling precise adjustment of the buffering effect. This helps ensure that the buffer device delivers the desired cushioning effect when subjected to shock or vibration, enhancing its stability and reliability. The combination of the washer 22 and nut 23 effectively prevents the buffer spring 20 from falling off or shifting during vibration or impact, ensuring that the buffer spring 20 remains in the correct position, ensuring proper operation of the device. The nut 23, secured to the second guide pin 21, forms a stable connection with the washer 22, enhancing the rigidity and stability of the buffer device, enabling it to better withstand external shock and vibration. This also helps reduce noise and wear caused by vibration or impact, extending the device's service life. The design of the washer 22 and the nut 23 makes it easier to install and replace the buffer spring 20. During installation, the buffer spring 20 only needs to be placed on the second guide pin 21 and then secured with the washer 22 and the nut 23. During maintenance, if the buffer spring 20 needs to be replaced or adjusted, it can also be easily achieved by removing the nut 23 and the washer 22.

[0060] In this embodiment, the other end of the second guide pin 21 is fixed to the sliding arm 10. The sliding arm 10 also has a first guide pin 11 fixed thereto. A second spring 29 and a retaining sleeve 30 are attached to the other end of the first guide pin 11. The first guide pin 11 forms a sliding pair with the base 12, and a support plate 9 is mounted on the base 12, which is then protected by a support plate protection pad 8. This sliding pair provides a stable guide and sliding path for the sliding arm 10, ensuring that the sliding arm 10 can slide smoothly along a predetermined trajectory without deflection or shaking when subjected to external forces. The second spring 29 and retaining sleeve 30 provide a buffering and retaining function for the sliding arm 10. When the sliding arm 10 is subjected to impact or vibration, the second spring 29 absorbs and dissipates this energy, thereby reducing the impact on other parts of the device. Furthermore, the retaining sleeve 30 limits the range of movement of the sliding arm 10, preventing excessive movement that could cause damage or safety accidents. The setting of the support plate 9 and the support plate protection pad 8 provides additional support and protection for the clamping device or workpiece. The support plate 9 can bear part of the weight and force, while the support plate protection pad 8 can prevent direct contact with the support plate 9, thereby avoiding scratches or damage.

[0061] In this embodiment, the loading device includes a loading support frame 1 and a gantry 45 . The gantry 45 is disposed on the top of the loading support frame 1 , and the tray 3 is disposed on the top of the gantry 45 .

[0062] In a second aspect, a method for clamping and flipping an automated high-voltage switch operating mechanism is provided, wherein the method is performed using the clamping and flipping mechanism as described above. Figure 4 As shown, including:

[0063] S101. Place the operating mechanism to be flipped on the conveying device so that it can be moved to the load device. For example, the entire clamping and flipping mechanism is controlled by a PLC controller. There are magnetic rings in the clamping cylinder 27 and the lifting cylinder 47. When the clamping cylinder 27 contracts or extends, the magnetic rings return a signal to the PLC controller. The PLC controller counts for several seconds and then issues a signal for the next action. At the same time, the mounting plate 40 and micro switch 41 provided in the device are used to cut off the power supply of the reducer 24 circuit and the control circuit signal when the flipping mechanism to be flipped is flipped into place. The specific operating principle is as follows: before the clamping and flipping mechanism is operated, it is in the initial position, and the square tube 42 and the first operating arm 18 and the second operating arm mounted thereon are in the raised state. When the clamping operation is required, the operating mechanism to be flipped is placed on the rotary disc 2 of the conveying device and, together with the entire conveying device, is transferred to the load support frame 1 of the load device via the conveyor belt. At this time, pressing the remote control button issues a command for the mechanism to clamp and flip.

[0064] S102. Utilize the control device to coordinate the turning device, the flexible clamping device, and the buffer device to turn the operating mechanism to be turned 180 degrees. For example, upon receiving the command, the PLC controller energizes the circuit of the reducer 24, causing the reducer 24 to rotate, driving the turning device, the clamping device, the buffer device, and the clamped operating mechanism to rotate 180 degrees about the first axis 37 to the top of the load support frame 1. At this point, the microswitch 41 switches, de-energizing the circuit of the reducer 24 and simultaneously issuing a descent command.

[0065] After receiving the command, the PLC controller activates the solenoid valve, controlling the retraction of the lifting device's lifting cylinder 47 and lifting piston rod 46, driving all other devices, except the load device and conveyor, downward. Once lowered to the preset position, the magnetic ring inside the lifting cylinder 47 sends a signal to the PLC controller indicating it has reached its full position. Several seconds later, the PLC controller issues a clamping command. Upon receiving the clamping command, the solenoid valve controls the retraction of the clamping cylinder 27 and piston rod 31. Once retracted to the preset position (clamping complete), the magnetic ring inside the clamping cylinder 27 sends a signal to the PLC controller indicating it has reached its full position. Several seconds later, the PLC controller issues a reversing command. Upon receiving the clamping command, the circuit of the reducer 24 is energized, causing the reducer 24 to rotate, driving the reversing device, the clamping device, the buffer device, and the operating mechanism to be reversed about the first axis 37. Once fully reversed 180 degrees, the second operating arm 36 presses the microswitch 41, switching it on. This disconnects the power supply to the reducer 24 circuit and sends a release command to the PLC controller. After a few seconds, the PLC controller receives the command and the solenoid valve controls the clamping device's clamping cylinder 27 and piston rod 31 to relax, disconnecting the control signal. At this point, the buffer device cushions and supports the clamping and flipping mechanism, while the flipping mechanism returns to its initial position. The flipping operation is now complete, and the sealing strip can be applied manually. Once this is complete, the operating mechanism can be manually moved to the storage area, and the device can be controlled again to finish applying the sealing strip to the next machine.
