[0039] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] like Figure 1As shown, an embodiment of the present invention provides a three-axis heavy-load positioner, including a flip mechanism 110, a lifting mechanism 120 and a slewing mechanism 130, the flip mechanism 110 includes a fixed bracket 111 and a flip assembly 112, the fixed bracket 111 is fixed to the ground, the flip assembly 112 is rotatably arranged on the fixed bracket 111, and the rotation center line of the flip assembly 112 is arranged horizontally, the lifting mechanism 120 includes a connecting assembly 121 and a lifting assembly 122, the connecting assembly 121 is installed on the flip assembly 112, and the lifting assembly 122 is installed on the flip assembly 112. 2 is installed on the connecting assembly 121, the lifting assembly 122 is used for lifting in the vertical direction, the slewing mechanism 130 includes a lifting bracket 131, a slewing assembly 132 and a locking structure 133, the lifting bracket 131 is installed on the lifting assembly 122, the slewing assembly 132 is rotatably arranged on the lifting bracket 131, the rotation center line of the slewing assembly 132 is arranged vertically, the slewing assembly 132 is used for carrying the electric wheel, the locking structure 133 is arranged on the slewing assembly 132, and the locking structure 133 is used to lock the electric wheel to the slewing assembly 132.

[0041] In this embodiment, through the coordinated work of three mechanisms, the three-axis heavy-duty positioner can achieve all-round adjustment of the electric wheel, which can improve the maintenance efficiency. The fixed bracket 111 in the flip mechanism 110 is fixed to the ground and the flip assembly 112 is set on the fixed bracket 111, which enhances the stability of the flip mechanism 110. The horizontal setting of the rotation center line of the flip assembly 112 helps to maintain the stability of the electric wheel during the flipping process and reduce the safety risks caused by the unstable center of gravity. Among them, the position of the electric wheel is adjusted by rotating the flip assembly 112. The lifting mechanism 120 allows the electric wheel to adjust its height in the vertical direction, which can quickly change the working height, reduce the time of manual handling and adjustment, and improve work efficiency and flexibility of operation. The design of the slewing assembly 132 allows the electric wheel to rotate 360° around its own axis, so that the electric wheel can be directly turned to the position where maintenance is required, reducing additional handling steps. The locking structure 133 on the slewing assembly 132 fixes the electric wheel on the slewing assembly 132 to prevent the electric wheel from falling off due to vibration or movement during operation, thereby improving the safety of operation. This solution can simplify the maintenance process. The position of the electric wheel can be adjusted by controlling the lifting mechanism 120 and the rotating mechanism 130, without the need for manual handling, thereby improving the efficiency and safety of maintenance.

[0042] like Figure 1 As shown, there are two flipping mechanisms 110 , and the two flipping components 112 of the two flipping mechanisms 110 are located between the two fixed brackets 111 , and the two flipping components 112 are coaxially arranged.

[0043] In this embodiment, two flipping mechanisms 110 and two flipping assemblies 112 of the two flipping mechanisms 110 are coaxially arranged to ensure force balance during the flipping process, reduce eccentric torque, thereby increasing the stability of the three-axis heavy-load positioner, and also reduce the stress bearing strength on each flipping mechanism 110, thereby extending the service life of the flipping mechanism 110. The coaxial arrangement of the flipping assembly 112 can also more accurately control the flipping action.

[0044] Preferably, two flipping mechanisms 110 are provided to provide a safeguard. If a flipping mechanism 110 fails during operation, the other flipping mechanism 110 can work independently, and maintenance work will not be stopped due to a failure of a flipping component 112. Safety accidents during the flipping process can also be prevented.

[0045] like Figure 1 There are two lifting mechanisms 120 shown, and the two connecting components 121 of the two lifting mechanisms 120 are respectively connected to one flip component 112 , and the lifting bracket 131 is connected to both lifting components 122 .

[0046] In this embodiment, by having two lifting mechanisms 120 working simultaneously, the stability of the three-axis heavy-load positioner can be improved. Especially when the gravity is large, the two lifting mechanisms 120 share the gravity, which can distribute the force more evenly during the lifting process, reduce the stress of a single component, and extend the service life of the lifting mechanism 120.

[0047] Preferably, two lifting mechanisms 120 are provided to play a safeguard role. If one lifting mechanism 120 fails, the other can continue to work, thereby ensuring safety during operation.

[0048] Furthermore, the flip assembly 112 includes a flip bearing with external teeth, and the flip mechanism 110 also includes a flip motor 113 installed on the fixed bracket 111, and the output shaft of the flip motor 113 is meshed with the external teeth of the flip bearing through a gear.

[0049] In this embodiment, the meshing of the gear and the outer teeth of the flip bearing can provide efficient power transmission. Due to the compactness of the gear structure and the high torque transmission efficiency, the power of the motor can be effectively converted into the flipping power of the flip bearing. Through the motor drive, the speed and flipping position can be accurately controlled to ensure the accuracy of the flipping operation. In addition, the gear transmission can withstand higher loads, which is very suitable for scenarios where heavy objects need to be flipped.

[0050] Among them, the connecting component 121 includes a matching nut, in which a ball is arranged, the lifting component 122 includes a lifting frame 123, a lifting screw rod 124 and a lifting motor 125, the lifting screw rod 124 and the lifting motor 125 are both installed on the lifting frame 123, the lifting screw rod 124 and the matching nut cooperate, the lifting motor 125 drives the lifting screw rod 124 to rotate, and the lifting screw rod 124 drives the lifting frame 123 to rise and fall when rotating, and the rotating mechanism 130 rises and falls with the lifting frame 123.

[0051] In this embodiment, the ball bearings provided in the nut can reduce the friction between the screw and the nut, making the lifting motion smoother, reducing wear, and reducing maintenance costs and maintenance frequency. The lifting motor 125 drives the lifting screw 124 to rotate, driving the lifting frame 123 to move up and down, and the height of the lifting frame 123 can be adjusted. Moreover, the slewing mechanism 130 can be lifted and lowered along with the lifting frame 123. Combined with the characteristic that the slewing mechanism 130 can rotate 360 ​​degrees, the slewing mechanism 130 can be lifted and lowered without manual handling, thereby improving the efficiency of maintenance.

[0052] like Figure 1 As shown, the lifting assembly 122 further includes a lifting guide rail 126 , which is disposed on the lifting frame 123 , and a fixed slide 114 is fixedly disposed on the flip assembly 112 , and the fixed slide 114 cooperates with the lifting guide rail 126 .

[0053] In this embodiment, the lifting rail 126 provides a fixed path for the lifting assembly 122 for the lifting frame 123 to move up and down along it, reducing the deformation or offset caused by the large gravity of the electric wheel, ensuring the accuracy of the lifting process. In addition, the lifting rail 126 system can reduce the friction and wear between the slewing mechanism 130 and the lifting mechanism 120. The cooperation between the fixed slide 114 and the lifting rail 126 can make the lifting of the slewing mechanism 130 smooth, reduce unnecessary vibration, and avoid the wear and safety hazards caused by it.

[0054] Furthermore, the slewing mechanism 130 further includes a flip swing arm 134 , one end of the flip swing arm 134 is connected to the lifting frame 123 , and the other end of the flip swing arm 134 is connected to the lifting bracket 131 .

[0055] In this embodiment, the angle of the lifting frame 123 relative to the lifting bracket 131 can be adjusted by flipping the swing arm 134, which increases the flexibility and adaptability of the operation. In addition, flipping the swing arm 134 can also increase the stability of the entire structure, especially during the flipping operation, which can provide better support and balance.

[0056] The rotary assembly 132 includes a rotary bearing with external teeth, and the rotary mechanism 130 also includes a rotary motor 135 installed on the lifting bracket 131. The output shaft of the rotary motor 135 is meshed with the external teeth of the rotary bearing through a gear.

[0057] In this embodiment, the meshing of the gear and the outer teeth of the slewing bearing can provide efficient power transmission. Due to the compactness of the gear structure and the high torque transmission efficiency, the power of the slewing motor 135 can be effectively converted into the power of the slewing bearing. Through the motor drive, the speed and position can be accurately controlled. In addition, the gear transmission can withstand higher loads, which is very suitable for scenes where heavy objects such as electric wheels need to be rotated.

[0058] like Figure 1 As shown, the slewing mechanism 130 further includes a plurality of tooling plates 140 of different sizes. Any tooling plate 140 can be detachably mounted on the slewing assembly 132 . The tooling plate 140 is used to connect with an electric wheel of matching size to mount the electric wheel on the slewing assembly 132 .

[0059] In this embodiment, by using tooling plates 140 of different sizes, the three-axis heavy-load positioner can adapt to electric wheels of different sizes, thereby increasing the versatility and flexibility of the three-axis heavy-load positioner. The detachable tooling plate 140 makes it quick and convenient to replace the electric wheel, thereby improving the efficiency of maintenance. Moreover, the tooling plate 140 can ensure the correct placement and positioning of the electric wheel, thereby reducing the risk of accidents caused by improper placement.

[0060] like Figure 1 As shown, there are multiple locking structures 133 , which are distributed along the circumference of the rotating assembly 132 . The locking structures 133 fix the tooling plate 140 to the rotating assembly 132 , so as to fix the electric wheel to the rotating assembly 132 .

[0061] In this embodiment, the locking structures 133 distributed along the circumference of the rotating assembly 132 can provide uniform pressure on the tooling plate 140, reduce the stress of a single locking point, extend the service life of the locking structure 133, and ensure the stability and safety of the tooling plate 140 on the rotating assembly 132 to prevent sliding or falling off during operation. Moreover, the provision of multiple locking structures 133 means that even if a locking point fails, other locking points can still keep the tooling plate 140 and the electric wheel fixed, thereby enhancing the reliability of the system.

[0062] A three-axis heavy-duty positioner provided in the present application realizes multi-dimensional adjustment of the electric wheel in space through the cooperation of the three mechanisms of the flipping mechanism 110, the lifting mechanism 120 and the rotating mechanism 130, which greatly improves the flexibility and efficiency of the electric wheel maintenance. The heavy-duty design is adopted, which can carry heavy electric wheels and meet the needs of large electric wheel processing. At the same time, through the detachable tooling plate 140 and the locking structure 133, the three-axis heavy-duty positioner can adapt to electric wheels of different sizes, which improves the versatility and adaptability of the equipment and improves the maintenance efficiency.

For those skilled in the art, the present invention may be modified and varied in various ways.

At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be considered as a part of the specification. In all examples shown and discussed here, any specific value should be interpreted as being only exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so that once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0066] In the description of this scheme, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing this scheme and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation.

[0068] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only to facilitate the distinction between corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this scheme.
