[0083] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0084] [Example 1]

[0085] like Figure 1 The motor rotor assembly device shown includes:

[0086] Rack 1;

[0087] A shift mechanism 11 is provided with a plurality of loading positions 12, the loading position 12 being used to place the barrel 51 of the motor 5, and the shift mechanism 11 is capable of transporting the barrel 51 of the previous station to the next station;

[0088] The press-fitting mechanism 2 is used to perform the press-fitting action to press-fit the rotor 53 and the upper cover 52 onto the barrel 51;

[0089] The screw mechanism 6 is used to connect the upper cover 52 to the upper end of the barrel 51 through bolts, thereby completing the assembly of the motor 5.

[0090] When the barrel 51, the upper cover 52 and the rotor 53 are placed on the loading position 12 at the discharge position, the shifting mechanism 11 can drive the loading position 12 to pass under the pressing mechanism 2 and the screwing mechanism 6 in turn, performing the pressing operation and the screwing operation respectively. After the assembly is completed, the motor 5 will be driven to the unloading position by the shifting mechanism 11.

[0091] In this technical solution, the motor 5 to be assembled can be placed on the loading station 12, and the subsequent press-fitting and screw-tightening actions can be automatically performed, making the assembly process of the motor 5 smoother and more convenient. At the same time, the loading and unloading tasks can be performed manually by an operator 19, or a robot can be set to place the motor 5 to be assembled on the loading station 12 or remove the assembled motor 5 from the loading station 12.

[0092] In this embodiment, the shifting mechanism 11 is a rotating disk 18. The design of the rotating disk 18 allows the press-fitting mechanism 2 and the screw-tightening mechanism 6 to be more compactly arranged on the frame 1, thereby reducing the overall space occupied by the equipment. As a preferred technical solution, the shifting mechanism 11 can also be a conveyor belt, which drives the motor 5 to be press-fitted through the press-fitting mechanism 2 and the screw-tightening mechanism 6 in sequence to complete the corresponding process.

[0093] like Figures 1-6 As shown, the press-fitting mechanism 2 includes:

[0094] Press-fit floating seat 24;

[0095] The press-fitting portion 21 is disposed on the press-fitting floating seat 24 , and a press-fitting cavity 22 is formed in the press-fitting portion 21 , and an opening is provided at the lower end;

[0096] a press-fitting rod 23 movably disposed in the press-fitting cavity 22;

[0097] The stage control component 4 is used to control the pressing mechanism 2 to independently perform the pressing action in different stages;

[0098] The driving assembly 27 is used to drive the press-fit floating seat 24 to move up and down.

[0099] In this embodiment, the press-fit portion 21 includes a connecting seat 25 and a sleeve portion 28, wherein the connecting seat 25 is disposed below the press-fit floating seat 24. When the sleeve portion 28 is connected below the connecting seat 25, the connecting seat 25 and the sleeve portion 28 cooperate to form a press-fit cavity 22.

[0100] A through hole 251 is formed on the connecting seat 25 . The through hole 251 is communicated with the press-fitting cavity 22 . The upper end of the press-fitting rod 23 is inserted into the through hole 251 .

[0101] The lower end of the press rod 23 is formed with a pressing seat 231. When the sleeve portion 28 is connected to the connecting seat 25, the pressing seat 231 is movably arranged in the press cavity 22. The pressing seat 231 cannot pass through the through hole 251.

[0102] A convex ring portion 29 is formed on the bottom end of the sleeve portion 28 . The convex ring portion 29 is used to prevent the pressing seat 231 from falling out of the press-fitting cavity 22 from below.

[0103] During the press-fitting operation, as the press-fitting floating seat 24 moves downward, the rotor shaft 54 ​​passes through the convex ring portion 29 into the press-fitting cavity 22 and abuts against the lower end of the abutting seat 231. This allows the press-fitting rod 23 to push the rotor shaft 54 ​​and press the rotor into place.

[0104] Furthermore, a bracket 13 is provided on the frame 1, and the press-fitting mechanism 2 is provided on the bracket 13;

[0105] A plurality of optical axes 15 are provided on the press-fit floating seat 24 , and the optical axes 15 extend upward from the upper top plate 14 of the bracket 13 .

[0106] The top of the optical axis 15 is connected to an optical axis connecting plate 16, which is used to limit the position of the optical axis 15 to ensure that the press-fit floating seat 24 can accurately move in the vertical direction. The optical axis connecting plate 16 has an escape hole 17 formed in it, which is used to avoid the drive assembly 27.

[0107] Specific as Figure 2-Figure 5 As shown, the connection base 25 is further provided with a plug hole 252 , which is communicated with the through hole 251 .

[0108] The stage control assembly 4 includes a stopper 42 and a second driving cylinder 41 for driving the stopper 42 to move.

[0109] In this technical solution, the press-fitting action includes two press-fitting stages.

[0110] Pressing stage 1:

[0111] Specific as Figure 4 As shown, the driving cylinder 2 41 of the stage control component 4 drives the stopper 42 to be inserted into the insertion hole 252, and the stopper 42 passes through the through hole 251. Thereby, the stopper 42 blocks the moving path of the press rod 23 in the through hole 251.

[0112] The drive assembly 27 drives the floating press-fit seat 24 downward until the rotor shaft 54 ​​extends from the opening at the lower end of the press-fit portion 21 into the press-fit chamber 22. As the floating press-fit seat 24 continues to descend, the pressing seat 231 of the press-fit rod 23 presses against the upper end of the rotor shaft 54. However, the upper end of the press-fit rod 23 is blocked by the stopper 42 and cannot move upward along the through hole 251. This allows the pressing seat 231 to push against the rotor shaft 54 ​​and press-fit the rotor 53 to the designed position.

[0113] Pressing stage 2;

[0114] Specific as Figure 5 As shown, in the second press-fitting stage, the second driving cylinder 41 of the stage control component 4 drives the stopper 42 to no longer block the through hole 251 .

[0115] When the pressing seat 231 of the press rod 23 presses against the upper end of the rotor shaft 54, the stopper 42 no longer blocks the through hole 251, allowing the press rod 23 to continue moving upward. Consequently, the upper end of the press rod 23 can continue moving upward along the through hole 251, allowing the lower end of the sleeve portion 28 to press against the upper cover 52, thereby pressing the upper cover 52 tightly against the upper end of the barrel 51.

[0116] As a preferred embodiment, a spring 232 is sleeved on the outside of the press-fitting rod 23 , and the spring 232 is arranged in the press-fitting cavity 22 . Both ends of the spring 232 abut against the abutting seat 231 and the side wall of the press-fitting cavity 22 respectively.

[0117] When in the second press-fitting stage, the rotor shaft 54 ​​pushes the press-fitting rod 23 to move upward, which causes the spring 232 to compress, so that the spring 232 can generate a reaction force to push the rotor shaft 54 ​​downward, maintaining pressure on the rotor shaft 54, and continuously fixing the position of the rotor 53 through the press-fitting rod 23 to ensure assembly accuracy.

[0118] like Figures 1-6 As shown, the press-fitting mechanism 2 further includes a press plate 26 , which is connected to the lower end of the press-fitting floating seat 24 via a connecting column 262 .

[0119] After the press-fitting mechanism completes press-fitting the rotor 53, in press-fitting stage 2, the drive assembly 27 drives the press-fitting floating seat 24 downward. The pressing plate 26 is connected to the press-fitting floating seat 24 via the connecting post 262. The sleeve portion 28 is connected to the lower end of the connecting seat 25, so that the pressing plate 26 can also move synchronously with the sleeve portion 28. When the lower end of the sleeve portion 28 abuts against the upper cover 52, the pressing plate 26 also abuts against the circumference of the upper cover 52, cooperating with the sleeve portion 28 to press the upper cover 52 against the barrel 51.

[0120] The pressing plate 26 presses against the circumference of the upper cover 52 , so that the upper cover 52 is evenly stressed, thereby preventing the upper cover 52 from being deformed during the press-fitting process.

[0121] Furthermore, a press-fitting mold 261 is provided on the pressing plate 26 , and the press-fitting mold 261 matches the contour of the upper cover 52 , so that the press-fitting mold 261 can be sleeved on the upper end of the pressing plate 26 .

[0122] like Figures 1-6 As shown, a directional mechanism 3 is also provided on the frame;

[0123] The orientation mechanism 3 includes:

[0124] Drive cylinder 4 31;

[0125] The insert 33 is connected to the driving cylinder 24 31, and the driving cylinder 24 31 can drive the insert 33 to rise or fall.

[0126] In this embodiment, a protrusion 57 is formed on the outer wall of the barrel 51 , and a sleeve portion 58 is formed on the upper cover 52 . The sleeve portion 58 can be sleeved on the outer side of the protrusion 57 .

[0127] The sleeve portion 58 is provided with a bore 59 .

[0128] When the motor 5 is set on the loading position 12 and the upper cover 52 is placed on the barrel 51 , the drilled holes 59 will be aligned with the screw holes on the raised portion 57 to facilitate the subsequent screwing of the upper cover 52 to the barrel 51 .

[0129] The orientation mechanism 3 can drive the insert 33 to move by driving the cylinder 24 31, and enable the lower end of the insert 33 to be simultaneously inserted into the drill hole 59 and the screw hole to fix the position of the upper cover 52 and the barrel 51.

[0130] When the motor 5 no longer needs to be fixed, the driving cylinder 24 31 can drive the insert 33 to move upward, so that the insert 33 is separated from the drill hole.

[0131] A rotating seat 32 is rotatably provided on the push rod of the driving cylinder 29 31, and an insert 33 is provided on the rotating seat 32. When the insert 33 is not needed, the insert 33 can be moved away from the top of the loading position 12 by rotating the position of the rotating seat 32.

[0132] Therefore, it should be noted that the height of the press-fitting mechanism 2 and the screw-tightening mechanism 6 is higher than the height of the driving cylinder 4 31.

[0133] like Figure 7 and Figure 8 As shown, a tooling quick-change plate 10 is provided on the loading position 12 , and different tooling quick-change plates 10 can be replaced according to the actual conditions of the motor 5 to be processed so as to cope with different production tasks.

[0134] In this embodiment, what needs to be assembled is a motor 5 with a fan blade 56. During assembly, the lower end of the rotor shaft 54 ​​needs to be inserted into the connecting hole 561 of the fan blade 56.

[0135] Therefore, the tooling quick-change plate 10 in this embodiment is formed with:

[0136] A support base 101 is used to support the barrel 51;

[0137] The fan blade positioning seat 102 is used to fix the position of the fan blade 56.

[0138] The blade positioning seat 102 is arranged on the inner side of the support seat 101 so as to keep the rotor 53 and the blades 56 coaxial. When the motor 5 is placed on the blade positioning seat 102, the rotor 53 and the blades 56 are aligned, and the rotor shaft 54 ​​is pressed into the connecting hole 561 during press-fitting.

[0139] Furthermore, a positioning hole 108 is formed on the fan blade positioning seat 102, and the positioning hole 108 is used to penetrate the positioning pin 104. The positioning pin 104 can further fix the position of the fan blade 56 placed on the fan blade positioning seat 102.

[0140] As another preferred technical solution, two positioning vertical rods 103 are provided on the support base 101 .

[0141] In this embodiment, a protrusion 57 is formed on the outer wall of the barrel 51, and a sleeve portion 58 is sleeved on the protrusion 57;

[0142] When the motor 5 is placed on the support base 101 , the raised portion 57 and the sleeve portion 58 can be inserted between the positioning vertical rods 103 to fix the positions of the barrel 51 and the upper cover 52 .

[0143] like Figure 1 and Figure 9 As shown, the screw-tightening mechanism 6 includes:

[0144] A screw-tightening assembly 7, which is used to perform a screw-tightening action;

[0145] A photographing assembly 8, which is used to take photos to determine whether the upper cover 52 and the barrel 51 are aligned;

[0146] The robotic arm 61 is provided with a mounting platform 62 , on which the screw-tightening assembly 7 and the photographing assembly 8 are both provided.

[0147] When the motor 5 to be assembled moves to below the screwing mechanism 6, the mechanical arm 61 first drives the photographing assembly 8 to move above the barrel 51 to take pictures. The camera 81 is used to take pictures, so that the position of the drill hole 59 on the upper cover 52 can be determined.

[0148] Then, the screw-tightening assembly 7 is moved to above the motor 5 so that the screw-tightening assembly 7 can perform the screw-tightening action and screw the upper cover 52 onto the barrel 51 .

[0149] A fixing assembly 9 is provided on the frame 1 , and the fixing assembly 9 includes a third driving cylinder 91 and a pressing member 92 connected to the third driving cylinder 91 .

[0150] The driving cylinder 3 91 is used to drive the pressing member 92 to move in the vertical direction, so that the pressing member 92 can press against the upper cover 52 and press the upper cover 52 against the barrel 51. The position of the upper cover 52 can be further fixed by the fixing assembly 9, so that the upper cover 52 can be stably fixed above the barrel 51, so that the position between the upper cover 52 and the barrel 51 remains stable during the screw-tightening operation, thereby improving the accuracy of the screw-tightening operation.

[0151] An escape groove 93 is formed at the end of the pressing member 92 . When the pressing member 92 presses against the upper end of the upper cover 52 , the rotor shaft 54 ​​can pass through the escape groove 93 .

[0152] like Figure 9 and Figure 10 As shown, the screw assembly 7 includes:

[0153] An actuator motor 71 is connected to a screwdriver 76 for tightening a screw;

[0154] The screw assembly seat 72 is formed with a tightening hole 73 , a fixing hole 74 and a feed port 75 . The fixing hole 74 is aligned with the drilled hole 59 of the upper cover 52 .

[0155] The feed port 75 is used for loading screws. After the screws enter the screw assembly seat 72 through the feed port 75 , they can fall into the fixing holes 74 .

[0156] The screwdriver 76 is inserted into the screw assembly seat 72 through the tightening hole 73 , and the tightening hole 73 and the fixing hole 74 are located on the same axis, so that the screwdriver 76 can be accurately connected with the screw and tighten the screw.

[0157] Furthermore, a slide cylinder 63 is provided on the mounting platform 62, and the slide cylinder 63 is connected to the mounting frame 64. The screw tightening component 7 and the photo-taking component 8 are both provided on the mounting frame 64, and the slide cylinder 63 can drive the mounting frame 64 to move up and down.

[0158] When performing photographing and screwing actions on motors 5 of different specifications and sizes, the slide cylinder 63 can also drive the screwing assembly 7 and the photographing assembly 8 to move to a suitable height so that the screwing assembly 7 and the photographing assembly 8 can perform corresponding actions.
