[0023] The technical solutions of the present utility model will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Combination Figures 1 to 8As shown, a combined mechanism for the rotor and stator of an air-suspended motor includes a horizontally arranged workbench 2 and a rotor positioning device and a rotor picking device respectively arranged on the top surface of the workbench 2. The rotor positioning device includes a rotating positioning seat slidably arranged on the top surface of the workbench 2. The rotating positioning seat includes a first slide 3 slidably arranged horizontally on the workbench 2 and a rotating parallel pneumatic gripper 4 slidably arranged vertically on the first slide 3. The top end of the rotating parallel pneumatic gripper 4 is connected to a rotor seat 41 and a gripper 42. The rotor picking device includes a gantry frame 5 arranged on the workbench 2 and an error prevention device 6 and a gripping device arranged on the gantry frame 5. The error prevention device 6 includes an error prevention plate 61 slidably connected to the gantry frame 5. The gripping device includes an elastic chuck 7 slidably connected to the gantry frame 5.

[0025] In this technical solution, the workbench is a conventional table surface, horizontally set using conventional support rods. The assembled rotor is fed into the rotary positioning seat by external manual labor or a robotic arm. The servo motor at the bottom of the rotating parallel gripper drives the rotating parallel gripper, which in turn causes the gripper to hold the rotor and rotate the rotor seat and gripper together to adjust the rotor's angle. Then, the first slide moves the entire rotary positioning seat directly below the error-proofing device. The error-proofing plate extends to ensure the accuracy of the rotor's fixed angle. The elastic chuck grabs the rotor and moves it directly above the stator (not shown), completing the directional loading of the rotor. The structure and principle of the rotating parallel gripper are existing technologies. The gripper is connected to the rotary parallel gripper's gripper. The top of the rotor seat has a positioning groove corresponding to the rotor, and its two sides have clearance grooves corresponding to the gripper. The workbench has a horizontal groove corresponding to the servo motor of the rotating parallel gripper to avoid interfering with the overall movement of the rotary positioning seat. Air pipes and cables are protected by conventional tank chains.

[0026] For example, see Figures 1 to 3 As shown, the first slide block 3 is slidably mounted on the worktable 2 via the first rodless cylinder 31. The first rodless cylinder 31 is mounted on the top of the worktable 2 via the mounting bracket 32. The first slide block 3 is slidably connected to the mounting bracket 32 ​​via the first guide rail 33.

[0027] In this technical solution, the mounting bracket is assembled from conventional plates and other materials and fixed to the top of the workbench with conventional bolts. The first rodless cylinder is horizontally fixed to the mounting bracket with conventional cylinder brackets, and its slider passes through the corresponding side plate of the mounting bracket and is connected to the first slide block, thereby driving the first slide block to move back and forth. The first guide rail is fixed to the side of the mounting bracket near the first slide block with conventional bolts. The first slide block is connected to the slider of the first guide rail with bolts, which improves the accuracy and stability of the movement of the first slide block. Conventional dampers and sensors are also provided at both ends of the mounting bracket.

[0028] For example, see Figures 1 to 3As shown, the rotating parallel pneumatic gripper 4 is vertically slidably connected to the first slide block 3 via the lifting cylinder 34, and its top end slides through the first slide block 3 and is connected to the rotor seat 41.

[0029] In this technical solution, the first slide includes a vertical plate and a horizontal plate. The vertical plate is fixed to the slider of the first guide rail by bolts, etc. The horizontal plate has a connecting part protruding downward at one end near the vertical plate and is fixed to the top of the vertical plate by conventional bolts and pins. The lifting cylinder is a conventional cylinder and is fixed to the side of the vertical plate away from the first guide rail by bolts, etc. The rotating parallel gripper is connected to the push plate of the lifting cylinder by bolts, etc. The lifting cylinder drives the rotating parallel gripper to rise and fall relative to the first slide.

[0030] For example, see Figures 1 to 3 As shown, limit brackets 35 are respectively provided on both sides of the top of the first slide block 3, and a channel for the rotor commutator to pass through is formed between the two limit brackets 35. The top of the limit bracket 35 is recessed with a limit groove corresponding to the rotor commutator.

[0031] In this technical solution, the limiting groove corresponds to the snap-fit ​​boss of the commutator. Before the rotor is placed into the rotor seat, the lifting cylinder is in the extended state. After the rotor is placed into the rotor seat, the rotating parallel gripper drives the rotor to rotate to the corresponding angle (detected by the image detection device). The lifting cylinder drives the rotor seat to descend, and the two opposite snap-fit ​​bosses of the commutator enter the corresponding limiting grooves respectively, ensuring the accuracy of the rotor positioning angle.

[0032] For example, see Figure 1 , Figure 4 and Figure 5 As shown, one end of the error-proof plate 61 is provided with a plug-in slot corresponding to the rotor, and the other end is connected to the error-proof cylinder 62. The error-proof cylinder 62 is installed on the gantry frame 5 through the guide plate 63. The end of the guide plate 63 away from the error-proof cylinder 62 is provided with a through slot corresponding to the error-proof plate 61.

[0033] In this technical solution, the insertion slot of the anti-error plate is set to correspond to the rotor camshaft. After the rotor angle is adjusted, the rotary positioning seat moves as a whole to directly below the anti-error device. The piston rod of the anti-error cylinder extends, driving the feed to extend along the guide plate through the groove towards the rotor. The insertion slot of the anti-error plate is engaged on both sides of the rotor camshaft, indicating that the rotor is positioned accurately. The anti-error cylinder drives the anti-error plate to reset, and the rotor feeding device starts. If the insertion slot of the anti-error plate cannot be engaged on both sides of the rotor camshaft, that is, the piston rod of the anti-error cylinder cannot extend to the predetermined position (determined by conventional magnetic switches, etc.), it indicates that the rotor positioning is incorrect, and the machine stops and alarms.

[0034] For example, see Figure 1 as well as Figures 4 to 8As shown, the elastic chuck 7 is connected to the gantry frame 5 via the second slide block 8. The gantry frame 5 is equipped with a second rodless cylinder 81 that drives the second slide block 8 and a second guide rail 82 that is slidably connected to the second slide block 8.

[0035] In this technical solution, the gantry frame is assembled from conventional profiles or plates and fixed to the top surface of the workbench with bolts. The second rodless cylinder is fixed to the gantry frame with conventional cylinder brackets and slides through the corresponding top plate of the gantry frame and is connected to the second slide block, thereby driving the second slide block to move back and forth, that is, driving the elastic chuck to move back and forth. The second slide block is connected to the slider of the second guide rail with bolts, which improves the accuracy and stability of the movement of the second slide block.

[0036] For example, see Figure 1 as well as Figures 4 to 8 As shown, the second slide block 8 is equipped with a lifting electric cylinder 83, and the elastic chuck 7 is connected to the slider of the lifting electric cylinder 83 through the lifting seat 84.

[0037] In this technical solution, the lifting electric cylinder is an existing structure, and its driving device is a servo motor with a brake, which drives the elastic clamp to lift and lower through the lifting seat.

[0038] For example, see Figure 1 as well as Figures 4 to 8 As shown, the elastic chuck 7 includes a mounting head 71 mounted on the lifting seat 84, an outer cylinder 72 connected to the mounting head 71, and an inner cylinder 73 that slides elastically within the outer cylinder 72. A spring 74 is provided between the top end of the inner cylinder 73 and the mounting head 71. An annular first boss protrudes from the inner wall of the outer cylinder 72, and an annular second boss protrudes from the outer wall of the inner cylinder 73.

[0039] In this technical solution, the top of the mounting head has a first positioning post protruding and is embedded in the lifting seat, which facilitates the quick positioning and mounting of the elastic chuck and the lifting seat. The bottom of the mounting head and the top of the inner cylinder have a second positioning post and a third positioning post protruding respectively. The two ends of the spring are respectively sleeved on the second positioning post and the third positioning post to reduce the possibility of spring tilting. During the process of the lifting seat driving the elastic chuck to descend, the inner cylinder first contacts the rotor and abuts against the end face of the commutator, improving the stability of rotor fixation. Then the lifting seat continues to drive the elastic chuck to descend, the inner cylinder slides relative to the outer cylinder and squeezes the spring, and the outer cylinder moves directly to the set position. The interior of the inner cylinder is provided with a clearance hole that can accommodate the camshaft, and the bottom of the outer cylinder is provided with a stepped groove corresponding to the outer contour of the commutator. The outer wall of the inner cylinder and the inner wall of the outer cylinder also form a clearance cavity to accommodate the connector.

[0040] For example, see Figures 1 to 7As shown, the bottom wall of the outer cylinder 72 is recessed with four clearance grooves, two of which are connected to a plug-in piece 75, and the other two clearance grooves penetrate the outer cylinder 72 radially. The plug-in piece 75 is slidably arranged along the radial direction of the outer cylinder 72, and the end opposite to the outer cylinder 72 is connected to a plug-in cylinder 76.

[0041] In this technical solution, the stepped groove at the bottom of the outer cylinder is engaged with the bottom of the commutator. The four engagement protrusions of the commutator are located in the corresponding clearance grooves. The two insertion cylinders push the insertion piece to extend and slide to the bottom surface of the corresponding engagement protrusion, thereby fixing the rotor to the elastic clamp.

[0042] For example, see Figure 1 and Figure 4 As shown, it also includes an image detection device 9 and a decoder 10.

[0043] In this technical solution, both the image detection device and the decoder are existing structures. The image detection device is used to identify whether the rotary positioning seat has adjusted the rotor angle to the correct position, and the decoder is used to identify the rotor code, etc., to ensure that all rotors entering the rotor seat are qualified products.

[0044] In actual production, the assembled rotor is delivered to the decoder by external personnel or a robotic arm. The decoder confirms the rotor is a qualified product, preventing defective products from entering the assembly process. The qualified rotor is then placed into the rotor seat. The image detection device identifies the rotor's angle and, through an external control device, activates the rotating parallel gripper to adjust the rotor to a preset fixed angle. The lifting cylinder descends, and the corresponding locking boss of the rotor commutator falls into the limiting groove of the limiting bracket. The first rodless cylinder, through the first slide, moves the rotating positioning seat to directly below the error-proofing device. The piston rod of the error-proofing cylinder extends, causing the error-proofing plate to extend along the guide plate's through groove towards the rotor. The insertion slot of the error-proofing plate is engaged on both sides of the rotor camshaft, indicating accurate rotor positioning. The error-proofing cylinder resets the error-proofing plate, and the lifting cylinder raises the rotating parallel gripper, releasing the rotor. Simultaneously, the rotor picking device is activated, and the lifting cylinder, through the lifting seat, lowers the elastic chuck. The inner cylinder first contacts the rotor and abuts against the end corresponding to the commutator. To improve the stability of rotor fixation, the lifting seat continues to drive the elastic chuck to descend. The inner cylinder slides relative to the outer cylinder and compresses the spring. The stepped groove at the bottom of the outer cylinder is directly engaged with the bottom of the commutator. The four engagement bosses of the commutator are located in the corresponding clearance grooves. The two plug-in cylinders push the plug-in pieces out and slide to the bottom surface of the corresponding engagement bosses, thereby fixing the rotor to the elastic chuck. The lifting electric cylinder drives the elastic chuck to rise through the lifting seat, disengaging the rotor from the rotor seat. The second rodless cylinder drives the elastic chuck to move horizontally to the stator fixing position or other transfer device. After reaching directly above the stator fixing position, the lifting electric cylinder drives the elastic chuck to descend through the lifting seat and presses the rotor onto the stator. The two plug-in cylinders drive the plug-in pieces to reset and disengage from the commutator. The lifting electric cylinder drives the elastic chuck to rise, and the outer cylinder rises accordingly. The spring releases its elastic potential energy, and the inner cylinder remains stationary until the first and second bosses abut against each other. The inner cylinder then rises and resets, starting the next cycle of rotor positioning and feeding.

[0045] In summary, the combined structure of the rotor and stator of the air-suspended motor of this utility model is simple, used for directional feeding of the rotor, realizes automated assembly of the air-suspended motor, and improves production efficiency.
