Technical Field
[0001] This application relates to the field of motor bearing assembly technology, and in particular to a motor bearing assembly device. Background Technology
[0002] Currently, electric motors, as key devices that convert electrical energy into mechanical energy, are widely used in industrial production and daily life. In the manufacturing and assembly process of electric motors, the assembly of the stator, rotor, end caps, and bearings is a crucial step. Bearings play a vital role in supporting the shaft and reducing friction. Typically, two bearings (e.g., a front bearing and a rear bearing) are assembled on a single motor housing (or end cap assembly), and these two bearings are usually located at different positions or depths within the housing. The quality of this assembly directly affects the smoothness of the motor's operation and its service life.
[0003] Currently, motor bearing assembly often employs a single-station press-fit method. Typically, an operator manually places the first bearing onto one end of the motor housing, then activates a single-station press to press it in. The workpiece is then flipped or moved to another station, and the second bearing is manually placed and pressed in using the same method. The entire process relies on repetitive manual loading, positioning, and equipment operation by the operator. However, in this assembly method, the assembly of the two bearings must be performed step-by-step at a single or limited number of stations, and the reliance on manual handling and intervention between steps results in a slow overall production cycle and low assembly efficiency. Summary of the Invention
[0004] To address the problems of low automation and cumbersome process flow leading to low production efficiency in existing motor bearing assembly methods, this application provides a motor bearing assembly device.
[0005] Firstly, the motor bearing assembly device provided in this application adopts the following technical solution: A motor bearing assembly device, the motor bearing assembly device comprising: The machine base has a plurality of processing stations arranged at intervals along its circumference. The plurality of processing stations include a loading / unloading pressing station, a first loading station, a first pressing station and a second loading station. The machine base also has a first feeding station and a second feeding station. The first feeding station is used to supply a first bearing and the second feeding station is used to supply a second bearing. The first feeding station and the second feeding station are respectively arranged corresponding to the first loading station and the second loading station. A rotating platform is rotatably mounted on the base about an axis extending vertically. The rotating platform has multiple installation stations, and each installation station can be sequentially placed on multiple processing stations during its rotational stroke. The first feeding module is located at the first feeding station and is used to transfer the first bearing at the first feeding station to the motor housing at the installation station located at the first feeding station. The first pressing module is located at the first pressing station and is used to press the first bearing at the installation station of the first pressing station to the motor housing. The second feeding module is located at the second feeding station and is used to transfer the second bearing at the second feeding station to the motor housing at the installation station located at the second feeding station. The second pressing module is located at the loading and unloading pressing station and is used to press the second bearing at the installation station of the loading and unloading assembly station to the motor housing. First, the motor housing is installed on the installation station corresponding to the loading and unloading pressing station. Driven by the rotating platform, the motor housing passes through the first loading station, the first pressing station, and the second loading station in sequence, and then returns to the loading and unloading pressing station, so that the first bearing and the second bearing can be pressed onto the motor housing in sequence.
[0006] By adopting the above technical solution, the continuous indexing motion of the rotating platform can not only replace the traditional manual handling and repeated clamping at a single station, significantly shortening the turnaround time between processes, but also combine the loading and unloading station with the second pressing station. This not only optimizes the spatial layout of the equipment and reduces the floor space, but also allows the loading and unloading operations and pressing operations to be tightly connected, thus effectively solving the problems of low automation and cumbersome process flow leading to low production efficiency in the existing motor bearing assembly method.
[0007] Optionally, both the first feeding module and the feeding module include: A first linear drive structure has a first fixed end and a first movable end, the first fixed end being disposed on the base, and the first movable end having a vertical travel. A feeding rotation structure includes a feeding rotation component and a feeding rotation drive structure. The feeding rotation drive structure has a mounting end and a rotating end, the mounting end being mounted on the first movable end, and the feeding rotation component being mounted on the rotating end, so that the feeding rotation component can rotate about a vertically extending axis; and... The feeding gripper is located on the feeding rotating component and is used to pick up and put down the bearing.
[0008] By adopting the above technical solution, the first linear drive structure is set to ensure accurate control of the material picking and placing depth so as to pick up and place bearings in the vertical direction. By setting the feeding rotation structure, the horizontal movement path from the feeding point to the assembly point can be simplified, making the mechanism more compact. At the same time, by setting the feeding claw, the bearings can be automatically picked up and released, avoiding bearing contamination or angle deviation that may be caused by manual operation, thereby ensuring that the bearings have a good consistent position before entering the pressing process.
[0009] Optionally, the feeding rotating component extends horizontally, and its middle part is mounted on the rotating end; Two feeding grippers are provided, and the two feeding grippers are respectively located at both ends of the feeding rotating component.
[0010] By adopting the above technical solution and setting two feeding grippers, on the one hand, alternating operations can be achieved, which greatly shortens the feeding interval. Compared with a single gripper that can only complete one pick-up and put-down operation per rotation, the double gripper can complete two pick-up and put-down operations in the same time, significantly improving the feeding speed. This, in turn, coordinates with the rotation rhythm of the rotating platform to ensure timely material supply to each workstation and avoids assembly stagnation caused by feeding delays. On the other hand, the two feeding grippers are symmetrically set, which makes the force on the feeding rotating parts more balanced during rotation, reduces rotational vibration caused by unilateral weight deviation, improves the positioning accuracy of the feeding grippers, and indirectly ensures the accuracy of bearing placement.
[0011] Optionally, the motor bearing assembly device further includes a material transfer module disposed on the machine base. The material transfer module is used to move the assembled motor housing at the installation station of the loading and unloading assembly station out, and to transfer the motor housing to be assembled to the installation station of the loading and unloading assembly station.
[0012] By adopting the above technical solution to connect with the rotating platform, on the one hand, the assembled motor housing can be moved out and the motor housing to be assembled can be moved in, further improving the automation of the device. On the other hand, it allows operators to stay away from moving mechanical parts and eliminates the need to frequently pick up and put down workpieces near the pressing module at the loading and unloading pressing station, thereby helping to improve the safety of the production process.
[0013] Optionally, the machine base is further provided with a third feeding station and an unloading station. The third feeding station is used to supply the motor housing, and the unloading station is used to place the assembled motor housing. The material transfer module includes: The material transfer sliding structure includes a material transfer sliding member movably mounted on the machine base in a horizontal direction. During its active stroke, the material transfer sliding member has a material transfer position and a clearance position. In the material transfer position, the material transfer module can transfer material. In the clearance position, the second pressing module can press the second bearing. The material transfer lifting structure includes a material transfer lifting component that is movably installed in the vertical direction on the material transfer sliding component; The material transfer rotating structure includes a material transfer rotating component rotatably mounted on the material transfer lifting component about an axis extending vertically; and, A material transfer gripper is provided on the material transfer rotating component; The moving gripper travels through the feeding station, the loading and unloading assembly station, and the unloading station to move the assembled motor housing out and move the motor housing to be assembled in.
[0014] By adopting the above technical solutions, a material transfer lifting structure is set up to vertically pick up and place workpieces, a material transfer rotating structure is set up to allow the material transfer grippers to switch between different work positions, and a sliding structure is set up to allow switching between the material transfer position and the avoidance position, so that the material transfer module can avoid the second pressing module and prevent the material transfer module from interfering with the second pressing module. This ensures the safety and stability of the pressing operation and enables efficient automatic flow of workpieces, so that the material transfer module can compactly complete all actions from feeding, assembly to unloading.
[0015] Optionally, three material transfer grippers are provided, and the three material transfer grippers can be respectively set to the feeding station, the loading and unloading assembly station and the unloading station.
[0016] By adopting the above technical solution, multiple sequential gripping and releasing actions can be parallelized in space, which can greatly optimize the material transfer process, significantly shorten the loading and unloading time, help reduce the waiting time of the entire assembly cycle, and allow the rotating platform to enter the next working cycle more quickly, thereby helping to improve the production efficiency of the entire device.
[0017] Optionally, the upper end of the material transfer sliding component is provided with a fixed sleeve, the material transfer lifting component includes a material transfer lifting rod passing through the fixed sleeve, and the material transfer rotating component is located at the upper end of the material transfer lifting rod; The material transfer lifting structure further includes a second linear drive structure, which has a second fixed end and a second movable end. The second fixed end is located on the material transfer sliding member, and the second movable end is driven to the lower end of the material transfer lifting rod to drive the material transfer lifting rod to move in the up and down direction.
[0018] By adopting the above technical solution and setting a second linear drive structure to provide a stable and uniform driving force, the structure is simple and the power transmission is direct. By setting a fixed sleeve to provide a stable guide for the material transfer lifting rod, the radial sway of the material transfer lifting rod is effectively limited, and the position deviation of the material transfer gripper is avoided due to component offset during the lifting process. This ensures that the material transfer gripper can accurately align with the motor housing of each station, thereby improving the accuracy of the picking and placing actions.
[0019] Optionally, a limiting structure is further provided between the fixed sleeve and the material transfer lifting rod. The limiting structure includes a limiting part and a mating part respectively disposed on the inner side wall of the fixed sleeve and the outer peripheral surface of the material transfer lifting rod. The limiting part and the mating part cooperate to limit the rotation of the material transfer lifting rod.
[0020] By adopting the above technical solution, the degree of freedom of the material transfer lifting rod to rotate relative to the fixed sleeve is restricted, so that it can only slide up and down, ensuring that the material transfer lifting rod will not transmit torque to the second linear drive structure, so that the material transfer lifting rod can be used to support the rotation of the material transfer rotating part.
[0021] Optionally, one of the limiting portion and the mating portion is a limiting protrusion and the other is a mating recess.
[0022] By adopting the above technical solution, the rotation of the material transfer lifting rod is restricted to prevent the material transfer lifting rod from transmitting torque, thereby enabling the material transfer lifting rod to support the rotation of the material transfer rotating component.
[0023] Optionally, the motor bearing assembly device further includes a mounting column that can be detachably installed at the installation station for the motor housing to pass through.
[0024] By adopting the above technical solution, the position of the motor housing can be located on the rotating platform to prevent it from shifting during rotation or pressing, which facilitates subsequent automatic feeding and pressing. At the same time, the detachable structure makes it easy to disassemble and assemble the positioning column, so that the positioning column can be replaced as needed, making the positioning column adaptable to motor housings of different specifications, thereby helping to improve the versatility of the rotating platform.
[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. By continuously indexing the rotating platform, it can replace the traditional manual handling and repeated clamping at a single station, greatly shortening the flow time between processes. It also combines the loading and unloading station with the second pressing station, which can not only optimize the spatial layout of the equipment and reduce the floor space, but also make the loading and unloading operation and pressing operation closely connected. This effectively solves the problems of low automation and cumbersome process flow leading to low production efficiency in the existing motor bearing assembly method. 2. By setting up a material transfer module, the material transfer sliding structure switches between the material transfer position and the avoidance position, so that the material transfer module can effectively avoid the second pressing module and prevent interference between the two. This design not only ensures the safety and stability of pressing operations at the same workstation, but also realizes the efficient automatic flow of workpieces. At the same time, it keeps the operators away from moving parts, improves the safety of the production process, and enables the material transfer module to complete all actions from feeding, assembly to unloading in a compact manner. 3. By setting a fixed sleeve and a limiting structure that cooperates with the material transfer lifting rod on the material transfer sliding component, the fixed sleeve provides a stable guide for the material transfer lifting rod, effectively limiting the radial sway of the material transfer lifting rod, and the limiting structure restricts the rotation of the material transfer lifting rod relative to the fixed sleeve, ensuring that the material transfer lifting rod only slides up and down without transmitting torque. This ensures that the material transfer gripper can accurately align with the motor housing of each station, improving the accuracy of the picking and placing action and the operational reliability of the equipment.

[0028] The following is in conjunction with the appendix Figure 1 - Appendix Figure 8 This application will be described in further detail below.
[0029] In one embodiment of this application, please refer to Figures 1 to 3The motor bearing assembly device 100 includes a base 1, a rotating platform 2, a first feeding module 3a, a first pressing module 4a, a second feeding module 3b, and a second pressing module 4b. The base 1 has multiple processing stations arranged sequentially and spaced apart along its circumference. These processing stations include a loading / unloading pressing station, a first feeding station, a first pressing station, and a second feeding station. The base 1 also has a first feeding station and a second feeding station. The first feeding station supplies a first bearing, and the second feeding station supplies a second bearing. The first feeding station and the second feeding station correspond to the first feeding station and the second feeding station, respectively. The rotating platform 2 is rotatably mounted on the base 1 about a vertically extending axis. The rotating platform 2 has multiple mounting stations, and each mounting station can be sequentially placed at multiple processing stations during its rotational stroke. The first feeding module 3a is located at the first feeding station and is used to load... The first bearing at the first feeding station is transferred to the motor housing at the installation station of the first loading station. The first pressing module 4a is located at the first pressing station to press the first bearing at the installation station of the first pressing station to the motor housing. The second loading module 3b is located at the second loading station to transfer the second bearing at the second feeding station to the motor housing at the installation station of the second loading station. The second pressing module 4b is located at the loading and unloading pressing station to press the second bearing at the installation station of the loading and unloading assembly station to the motor housing. The motor housing is first installed at the installation station corresponding to the loading and unloading pressing station. Driven by the rotating platform 2, the motor housing passes through the first loading station, the first pressing station, and the second loading station in sequence, and then returns to the loading and unloading pressing station so that the first bearing and the second bearing can be pressed onto the motor housing in sequence.
[0030] Understandably, the rotation of the rotating platform 2 allows the motor housing to automatically move between multiple workstations, cooperating with the dedicated loading or pressing modules at each workstation to complete bearing assembly. During operation, the motor housing is first placed at the installation station corresponding to the loading / unloading and pressing station. The rotating platform 2 then drives the motor housing sequentially through the first loading station, the first pressing station, and the second loading station, finally returning to the loading / unloading and pressing station. During this process, the first loading module 3a loads the first bearing at the first loading station, the first pressing module 4a presses the first bearing at the first pressing station, and the second loading module 3b loads the second bearing at the second loading station. Upon returning to the loading / unloading and pressing station, the second pressing module 4b completes the second bearing pressing. This allows each process to proceed synchronously or orderly at different workstations, avoiding the waiting time of traditional single-station step-by-step operations. Furthermore, each module is dedicated to a single action, making the action precision easier to control and reducing deviations caused by manual intervention. Please refer to [further details omitted]. Figures 1 to 3The first pressing module 4a and the second pressing module 4b both include a pressing head 41 and a pressing drive structure. The pressing head 41 is movably mounted on the frame in the vertical direction. The pressing drive structure drives the pressing head 41 to move in the vertical direction so as to press the bearing onto the motor housing.
[0031] In this embodiment, the continuous indexing motion of the rotating platform 2 can replace the traditional manual handling and repeated clamping at a single station, greatly shortening the flow time between processes. It also combines the loading and unloading station with the second pressing station, which not only optimizes the spatial layout of the equipment and reduces the floor space, but also allows the loading and unloading operations and pressing operations to be tightly connected. This effectively solves the problems of low automation and cumbersome process flow leading to low production efficiency in the existing motor bearing assembly method.
[0032] In one embodiment of this application, please refer to Figure 2 and Figure 3 Both the first feeding module 3a and the feeding module include a feeding mechanism. The feeding mechanism includes a first linear drive structure 31, a feeding rotation structure 32, and a feeding gripper 33. The first linear drive structure 31 has a first fixed end and a first movable end. The first fixed end is located on the machine base 1, and the first movable end has a vertical stroke. The feeding rotation structure 32 includes a feeding rotation component 321 and a feeding rotation drive structure 322. The feeding rotation drive structure 322 has a mounting end and a rotating end. The mounting end is mounted on the first movable end, and the feeding rotation component 321 is mounted on the rotating end so that the feeding rotation component 321 can be rotated around a vertically extending axis. The feeding gripper 33 is located on the feeding rotation component 321 and is used to pick up and put down the bearing. When a bearing needs to be transferred, the loading rotation drive structure 322 drives the loading rotation component 321 to rotate, aligning the loading gripper 33 with the bearing at the feeding station. Then, the first movable end of the first linear drive structure 31 moves downward, causing the loading rotation structure 32 and the loading gripper 33 to descend, and the loading gripper 33 grips the bearing. After gripping, the first movable end moves upward to reset, and the loading rotation component 321 rotates again, aligning the bearing with the motor housing at the installation station. Then, the first movable end descends again, and the loading gripper 33 releases the bearing, completing one bearing transfer. Thus, by setting the first linear drive structure 31, accurate control of the material handling depth is ensured for vertical bearing handling. The loading rotation structure 32 simplifies the horizontal movement path from the feeding point to the assembly point, making the mechanism more compact. Simultaneously, the loading gripper 33 automatically grips and releases the bearing, avoiding bearing contamination or angular deviations that may occur with manual operation, thereby ensuring a consistent bearing position before entering the pressing process.
[0033] In one embodiment of this application, a feeding rotating part is located in the middle of the feeding rotating member 321, and two feeding grippers 33 are provided, which are respectively located at both ends of the feeding rotating member 321. When feeding is performed, the feeding rotating drive structure 322 drives the feeding rotating member 321 to rotate around the middle rotating part. In the initial state, one feeding gripper 33 is aligned with the feeding station to grab the bearing, while the other feeding gripper 33 is in a standby state. After the gripping is completed, the feeding rotating member 321 rotates 180 degrees, the gripper with the bearing is aligned with the installation station to release the bearing, and at the same time, the other gripper rotates to the feeding station for the next gripping. During this process, the first linear drive structure 31 cooperates to complete the up and down lifting action, realizing the synchronous connection of picking up and unloading materials. Thus, by setting two loading jaws 33, on the one hand, they can work alternately, which greatly shortens the loading interval. Compared with a single jaw that can only complete one pick-up and put-down operation per rotation, the double jaws can complete two pick-up and put-down operations in the same time, which significantly improves the loading speed. This, in turn, coordinates with the rotation rhythm of the rotating platform 2 to ensure timely material supply to each station and avoid assembly stagnation caused by loading delays. On the other hand, the two loading jaws 33 are symmetrically set, which makes the loading rotating part 321 more evenly stressed during rotation, reduces rotational vibration caused by unilateral weight deviation, improves the positioning accuracy of the loading jaws 33, and indirectly ensures the accuracy of bearing placement.
[0034] In one embodiment of this application, the feeding mechanism further includes a feeding conveyor belt 34 disposed on the base 1 for supplying bearings to the corresponding feeding station. During the assembly process, the feeding conveyor belt 34 operates continuously, transporting the stored bearings one by one to the preset feeding station. After the conveyor belt delivers the bearing to the station, the feeding rotating structure 32 drives the feeding gripper 33 to rotate above the feeding station, and the first linear drive structure 31 drives the feeding gripper 33 to descend and grab the bearing at the feeding station, followed by subsequent transfer actions; at the same time, the feeding conveyor belt 34 continues to transport the next bearing, preparing for the next material retrieval. In this way, by setting up the feeding conveyor belt 34, the bearings can be continuously and evenly delivered to the feeding station, avoiding interruptions or deviations in the feeding process caused by inconsistent speed, omissions or misplacements during manual feeding. This ensures that the feeding module always has a stable supply of materials, guaranteeing the continuity of the assembly process. At the same time, it eliminates the need for workers to frequently travel between the bearing storage area and the feeding station, significantly reducing the labor intensity of workers in the feeding process, reducing manual input, and thus helping to reduce labor costs.
[0035] In one embodiment of this application, please refer to Figure 4 , Figure 5 and Figure 7The motor bearing assembly device 100 also includes a material transfer module 5 mounted on the base 1. The material transfer module 5 is used to move the assembled motor housing from the installation station at the loading / unloading assembly station and to transfer the motor housing to be assembled to the installation station at the loading / unloading assembly station. When the rotating platform 2 drives the motor housing with the completed double bearing assembly back to the loading / unloading pressing station, the material transfer module 5 moves, moving the assembled motor housing from the corresponding installation station; then, the material transfer module 5 moves the motor housing to be assembled to the vacated installation station, completing one loading / unloading cycle. During this process, the action of the material transfer module 5 is coordinated with the rotation of the rotating platform 2 and the pressing action of the second pressing module 4b, selecting appropriate times for material transfer to avoid interference with the actions of other components. Thus, by setting up the material transfer module 5 to dock with the rotating platform 2, on the one hand, the assembled motor housing can be moved out and the motor housing to be assembled can be moved in, further improving the automation of the device. On the other hand, it allows operators to stay away from moving mechanical parts and does not need to frequently pick up and put down workpieces near the pressing module of the loading and unloading pressing station, thereby helping to improve the safety of the production process.
[0036] In one embodiment of this application, please refer to Figure 4 and Figure 5 The base 1 is also provided with a third feeding station and an unloading station. The third feeding station is used to supply the motor housing, and the unloading station is used to place the assembled motor housing. The transfer module 5 includes a transfer sliding structure 51, a transfer lifting structure 52, a transfer rotating structure 53, and a transfer gripper 54. The transfer sliding structure 51 includes a transfer sliding member 511 that is movably mounted on the base 1 in the horizontal direction. In its active stroke, the transfer sliding member 511 has a transfer position that can transfer material and a position that can avoid material. When in the transfer position, the transfer module 5 can transfer material. When in the avoidance position, the second pressing module 4b can press the second bearing. The material transfer lifting structure 52 includes a material transfer lifting member 521 that is movably mounted on the material transfer sliding member 511 in the vertical direction. The material transfer rotating structure 53 includes a material transfer rotating member 531 that is rotatably mounted on the material transfer lifting member 521 about an axis extending in the vertical direction. The material transfer gripper 54 is provided on the material transfer rotating member 531. The moving stroke of the material transfer gripper 54 passes through the feeding station, the loading and unloading assembly station and the unloading station to move the assembled motor housing out and move the motor housing to be assembled into it.
[0037] Understandably, when the rotating platform 2 returns to the loading / unloading press-fitting station with a motor housing that has completed double bearing assembly, the material transfer module 5 is activated. First, the material transfer sliding component 511 moves to the material transfer position, aligning the material transfer gripper 54 with the loading / unloading press-fitting station; the material transfer lifting component 521 descends, and the material transfer gripper 54 grabs the assembled motor housing; then the material transfer lifting component 521 rises, and the material transfer rotating component 531 rotates, aligning the material transfer gripper 54 with the unloading station; the material transfer lifting component 521 descends again, placing the assembled motor housing at the unloading station. Next, the material transfer gripper 54 moves to the third feeding station, grabs a new motor housing to be assembled, and then moves to the loading / unloading press-fitting station, placing it on an empty installation station. After completion, the material transfer sliding component 511 moves to a clearance position, allowing space for the second press-fitting module 4b to perform the press-fitting action at this station, thus achieving automatic unloading of assembled parts and automatic loading of parts to be assembled.
[0038] In this embodiment, a material transfer lifting structure 52 is provided to vertically pick up and place workpieces. A material transfer rotating structure 53 is provided to allow the material transfer gripper 54 to switch between different work positions. A sliding structure is provided to allow switching between the material transfer position and the avoidance position, so that the material transfer module 5 can avoid the second pressing module 4b, so that the material transfer module 5 will not interfere with the second pressing module 4b. This ensures the safety and stability of the pressing operation and enables efficient automatic flow of workpieces. As a result, the material transfer module 5 can compactly complete all actions from feeding, assembly to unloading.
[0039] In one embodiment of this application, please refer to Figure 4 Three transfer grippers 54 are provided, each corresponding to a feeding station, an assembly station, and an unloading station. These three grippers are fixedly mounted on a transfer rotating component 531. As the rotating component rotates, the three grippers can precisely align with the three predetermined positions: the feeding station, the assembly station, and the unloading station. When the transfer module 5 completes a work cycle, the transfer lifting structure 52 descends once, commanding the three grippers to move simultaneously. For example, one gripper can place a finished product at the unloading station, another gripper can grab or place a workpiece at the assembly station, and the third gripper can grab a new housing at the feeding station. Through the precise indexing rotation of the transfer rotating structure 53, the stations served by each gripper can be quickly switched.
[0040] In this embodiment, by setting three material handling grippers 54, the material loading and / or unloading at one station can be completed in one lifting stroke, and the machine can quickly switch to the next target station by rotation. Compared with single or double grippers, which require multiple reciprocating movements and lifting to complete all tasks, the action path is shorter and the cycle time is less. In this way, multiple sequential gripping and unloading actions are parallelized in space, which can greatly optimize the material handling process, significantly shorten the loading and unloading time, help reduce the waiting time of the entire assembly cycle, and allow the rotating platform 2 to enter the next working cycle more quickly, thereby helping to improve the production efficiency of the entire device.
[0041] In one embodiment of this application, please refer to Figures 4 to 6 The upper end of the material transfer sliding member 511 is provided with a fixed sleeve 55. The material transfer lifting member 521 includes a material transfer lifting rod 5211 that passes through the fixed sleeve 55. The material transfer rotating member 531 is provided at the upper end of the material transfer lifting rod 5211. The material transfer lifting structure 52 includes a second linear drive structure 52242. The second linear drive structure 52242 has a second fixed end and a second movable end. The second fixed end is provided at the material transfer sliding member 511, and the second movable end is drivenly connected to the lower end of the material transfer lifting rod 5211 to drive the material transfer lifting rod 5211 to move in the up and down direction. When the vertical position of the material transfer gripper 54 needs to be adjusted, the second linear drive structure 52242 is activated, and its movable end pushes the lower end of the material transfer lifting rod 5211, causing the material transfer lifting rod 5211 to slide up and down along the channel inside the fixed sleeve 55. Due to the guiding effect of the fixed sleeve 55, the material transfer lifting rod 5211 will not deviate or shake during the movement, and will always maintain stable movement in the vertical direction. The upper end of the material transfer lifting rod 5211 drives the material transfer rotating component 531 and the material transfer gripper 54 to move up and down synchronously, thereby realizing the descent of the material transfer gripper 54 when picking up material and the rising action after discharging material. Thus, by setting a second linear drive structure 52242, a stable and uniform driving force is provided. The structure is simple and the power transmission is direct. By setting a fixed sleeve 55, a stable guide is provided for the material transfer lifting rod 5211, which effectively limits the radial sway of the material transfer lifting rod 5211 and avoids the position deviation of the material transfer gripper 54 caused by the offset of the components during the lifting process. This ensures that the material transfer gripper 54 can be accurately aligned with the motor housing of each station, and improves the accuracy of the picking and placing action.
[0042] In one embodiment of this application, please refer to Figure 4 and Figure 5The material transfer sliding structure 51 also includes a material transfer sliding drive structure 512 disposed between the frame and the material transfer sliding member 511, the material transfer lifting structure 52 also includes a material transfer lifting drive structure disposed between the material transfer lifting member 521 and the material transfer sliding member 511, and the material transfer rotating structure 53 also includes a material transfer rotating drive structure 532 disposed between the material transfer lifting member 521 and the material transfer rotating member 531. When the material transfer sliding component 511 needs to move, the material transfer sliding drive structure 512 is activated, driving the material transfer sliding component 511 to move precisely in the horizontal direction to the material transfer position or avoidance position. When the vertical position of the material transfer gripper 54 needs to be adjusted, the material transfer lifting drive structure operates, driving the material transfer lifting component 521 to move up and down, realizing the lifting and lowering of the material transfer gripper 54 to meet the height requirements when removing and discharging the generator housing. When the orientation of the material transfer gripper 54 needs to be adjusted to align with different workstations, the material transfer rotation drive structure 532 operates, driving the material transfer rotating component 531 to rotate, so that the material transfer gripper 54 is precisely aligned with the third feeding workstation, the loading and unloading pressing workstation, or the unloading workstation. In this way, the various drive structures cooperate with each other and operate in an orderly manner according to the preset program to ensure a smooth material transfer process.
[0043] It is understood that the material transfer sliding drive structure 512 can be of various types, including a pneumatic cylinder, a hydraulic cylinder, or a combination of a ball screw and a motor, etc. The embodiments of this application do not limit this type. Similarly, the material transfer lifting drive structure can be of various types, including a pneumatic cylinder, a hydraulic cylinder, or an electric actuator, etc. The embodiments of this application do not limit this type. The material transfer rotation drive structure 532 can be of various types, including a drive motor, a rotary cylinder, or a hollow rotary platform, etc. The embodiments of this application do not limit this type.
[0044] In one embodiment of this application, please refer to Figure 5 and Figure 6A limiting structure 56 is also provided between the fixed sleeve 55 and the material transfer lifting rod 5211. The limiting structure 56 includes a limiting part 561 and a mating part 562 respectively disposed on the inner side wall of the fixed sleeve 55 and the outer peripheral surface of the material transfer lifting rod 5211. The limiting part 561 and the mating part 562 cooperate to restrict the rotation of the material transfer lifting rod 5211. When the material transfer lifting rod 5211 moves up and down along the fixed sleeve 55, the limiting part 561 on the inner side wall of the fixed sleeve 55 and the mating part 562 on the outer peripheral surface of the material transfer lifting rod 5211 always remain in contact or engaged. Due to the structural limitation of the two, the material transfer lifting rod 5211 cannot rotate around its own axis and can only move linearly in the up and down direction. Thus, by setting the limiting structure 56, the degree of freedom of rotation of the material transfer lifting rod 5211 relative to the fixed sleeve 55 is restricted, allowing it to only slide up and down. This ensures that the material transfer lifting rod 5211 will not transmit torque to the second linear drive structure 52242, enabling the material transfer lifting rod 5211 to support the rotation of the material transfer rotating member 531. Further, in one embodiment of this application, one of the limiting part 561 and the mating part 562 is a limiting protrusion, and the other is a mating recess. Thus, the rotation of the material transfer lifting rod 5211 is restricted by the mutually mating limiting protrusion and mating recess, preventing the material transfer lifting rod 5211 from transmitting torque, thereby enabling the material transfer lifting rod 5211 to support the rotation of the material transfer rotating member 531.
[0045] It is understood that there are various ways in which the limiting part 561 and the mating part 562 can be configured. The limiting part 561 can be a limiting protrusion and the mating part 562 a mating groove, or the limiting part 561 can be a mating groove and the mating part 562 a limiting protrusion. The embodiments of this application do not limit this. Specifically, in one embodiment of this application, please continue to refer to... Figure 6 The recess extends axially along the material transfer lifting rod 5211, and the limiting protrusion is detachably installed on the fixing sleeve 55. When the lifting rod moves up and down, the protrusion slides within the recess, allowing axial displacement; however, when the lifting rod is subjected to torque and attempts to rotate, the side of the protrusion contacts the sidewall of the recess and generates a reaction force, thereby locking the rotation direction. Thus, the recess extending axially along the material transfer lifting rod 5211 to cooperate with the limiting protrusion not only restricts the rotation of the material transfer lifting rod 5211 but also serves as a guide, allowing the material transfer lifting rod 5211 to move vertically. The detachable structure facilitates the disassembly and assembly of the limiting protrusion for replacement as needed, and allows for adjustment of the position of the limiting protrusion to adjust the maximum stroke of the material transfer lifting rod 5211 to accommodate different lifting heights, thereby improving the versatility of the material transfer lifting structure 52. Of course, in other embodiments, the limiting protrusion can also be an elastic structure, such as a spring-loaded buckle or a rubber protrusion; the embodiments of this application do not limit this.
[0046] In one embodiment of this application, the limiting protrusion is provided with a mounting hole, the fixing sleeve 55 is provided with a through hole 551, and the limiting structure 56 further includes a fixing bolt 563. The fixing bolt 563 passes through the through hole 551 and is threaded through the mounting hole. The tightening force of the threaded connection firmly locks the limiting protrusion in the predetermined position of the fixing sleeve 55. The bolt, as a connecting member, bears the tensile force, ensuring that the protrusion will not loosen or shift when subjected to lateral force. Thus, by setting the fixing bolt 563, the disassembly and assembly of the structure becomes very simple and quick, requiring only standard tools to complete the operation without complex pressing or welding processes. This ensures the reliability of the connection, resists vibration during equipment operation, and greatly facilitates subsequent equipment debugging and component replacement, reducing the difficulty of equipment maintenance.
[0047] In one embodiment of this application, please refer to Figure 7 and Figure 8 The mounting hole includes a first hole segment 5511 and a second hole segment 5512 extending in the vertical direction. The width of the first hole segment 5511 is smaller than the width of the second hole segment 5512. Thus, by setting the first hole segment 5511 to match the diameter of the fixing bolt 563, it is convenient for the fixing bolt 563 to fix the limiting part 561 on the fixing sleeve 55. By setting the second hole segment 5512, the limiting part 561 can be inserted into the fixing sleeve 55 from the outside of the fixing sleeve 55, thereby facilitating the direct installation and removal of the limiting part 561.
[0048] In one embodiment of this application, please refer to Figures 1 to 3 The motor bearing assembly device 100 also includes a detachable mounting post 21 installed at the installation station for the motor housing to pass through. Before assembly, the positioning post is installed at a specific installation station on the rotating platform 2. During loading, the motor housing is simply fitted onto or aligned with the positioning post and lowered, achieving precise positioning of the housing in the horizontal plane and preventing movement during subsequent handling and pressing. Thus, by setting the mounting post 21, the position of the motor housing is positioned on the rotating platform 2, preventing displacement during rotation or pressing, facilitating subsequent automatic loading and pressing. The detachable structure also allows for easy disassembly and replacement of the positioning post as needed, enabling it to adapt to different specifications of motor housings and thus improving the versatility of the rotating platform 2.
[0049] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
