[0044] Referring to Figure 1 and Figure 2 , the magnetic ring press fitting machine provided by the embodiment comprises a rack 100, a shaft feeding mechanism 510, a press fitting device 200, a magnetic ring feeding mechanism 700 and a press fitting conveying mechanism 300. The rack 100 has a first direction X, a second direction Y and a vertical direction Z perpendicular to each other. The shaft feeding mechanism 510 is used for supplying motor shafts 10. In combination with Figure 11 , the press fitting device 200 comprises a press fitting support 210, a downward pressing driving member 220, a jacking driving member 230, a clamping driving member 240 and a press fitting head 250. The jacking driving member 230 and the downward pressing driving member 220 are installed in the press fitting support 210 in an upper and lower spaced manner, and the press fitting head 250 is installed on the output end of the downward pressing driving member 220. The output ends of the press fitting head 250 and the jacking driving member 230 are coaxially arranged in an upper and lower relationship, so as to clamp the motor shaft 10 in an upper and lower relationship, thereby ensuring the stability of the motor shaft 10 in the XY plane. The clamping driving member 240 is installed on the press fitting head 250, and the clamping driving member 240 is used for horizontally clamping the motor shaft 10.

[0045] In combination with Figure 3The magnetic ring feeding mechanism 700 comprises a first support 710, a feeding turntable 720, a sleeve feeding mechanism 730, a glue applying mechanism 740, a magnetic ring supplying mechanism 750 and a magnetic ring output mechanism 760 arranged in sequence around the feeding turntable 720. The feeding turntable 720 is rotatably mounted on the first support 710 in the vertical direction Z. The sleeve feeding mechanism 730 is configured to supply the core sleeve 31 to the feeding turntable 720. The glue applying mechanism 740 is configured to apply glue to the outer periphery of the core sleeve 31. The magnetic ring supplying mechanism 750 is configured to supply the magnetic ring member 32 to the feeding turntable 720, so that the magnetic ring member 32 is sleeved on the glued core sleeve 31 to form the magnetic ring assembly 30. The magnetic ring output mechanism 760 is configured to pick up the magnetic ring assembly 30 on the feeding turntable 720. The press fitting conveying mechanism 300 is configured to convey the motor shaft 10 from the shaft feeding mechanism 510 to the press fitting device 200, and convey the magnetic ring assembly 30 from the magnetic ring output mechanism 760 to the press fitting device 200.

[0046] Accordingly, the sleeve feeding mechanism 730 supplies the core sleeve 31 to the feeding turntable 720. The feeding turntable 720 rotates, so that the core sleeve 31 passes through the glue applying mechanism 740, the magnetic ring supplying mechanism 750 and the magnetic ring output mechanism 760 in sequence, i.e. the glue applying, the glue fitting of the magnetic ring member 32 to form the magnetic ring assembly 30, and the removal of the magnetic ring assembly 30 from the feeding turntable 720 are sequentially performed. The press fitting conveying mechanism 300 conveys the motor shaft 10 from the shaft feeding mechanism 510 and the magnetic ring assembly 30 from the magnetic ring output mechanism 760 to the press fitting device 200, respectively. The press fitting device 200 press fits the motor shaft 10 into the magnetic ring assembly 30 (see Figure 10 ). The magnetic ring press fitting machine integrates the automatic glue fitting of the magnetic ring assembly 30 and the sleeve press fitting, avoids the material transfer and waiting time when the assembly of the magnetic ring assembly 30 and the press fitting into the shaft are operated on different devices in the traditional way, shortens the overall production cycle, and improves the production efficiency. Moreover, the magnetic ring assembly 30 is assembled by glue fitting, which reduces the mechanical damage to the magnetic ring member 32 and the core sleeve 31, avoids the deformation of the components to affect the subsequent press fitting into the shaft, and ensures the coaxiality of the magnetic ring assembly 30 and the motor shaft 10 during the press fitting.

[0047] In some embodiments, in combination with Figure 4 and Figure 5The loading turntable 720 is provided with at least two positioning assemblies 721, and all the positioning assemblies 721 are distributed along the periphery of the loading turntable 720. When one positioning assembly 721 is working at a certain process (such as glue coating), the other positioning assemblies 721 can work synchronously at adjacent processes (such as sleeve loading, magnetic ring sleeving and assembly output), so as to greatly shorten the idle time of the equipment and improve the production efficiency. Specifically, the positioning assembly 721 is used for positioning and placing the sleeve 31, so as to ensure that the position of the sleeve 31 on the loading turntable 720 is fixed and the posture is uniform, avoid problems such as uneven glue coating and magnetic ring 32 skewing caused by the deviation of the sleeve 31, and improve the consistency of product quality.

[0048] Optionally, the number of the positioning assemblies 721 is four, and the four positioning assemblies 721 are uniformly and spacedly distributed on the edge of the loading turntable 720 around the vertical axis, that is, the central angle of the two adjacent positioning assemblies 721 is 90°. The four positioning assemblies 721 are simultaneously connected with the magnetic ring supply mechanism 750, the glue coating mechanism 740, the sleeve loading mechanism 730 and the magnetic ring output mechanism 760 respectively, so that the magnetic ring supply mechanism 750, the glue coating mechanism 740, the sleeve loading mechanism 730 and the magnetic ring output mechanism 760 can continuously work, and the production efficiency is improved.

[0049] In one embodiment, in combination with Figure 5 and Figure 6 , the positioning assembly 721 has a positioning groove 722, and the positioning groove 722 is used for limiting the sleeve 31 to be sleeved, so as to realize the horizontal positioning of the sleeve 31 on the positioning assembly 721. The groove bottom of the positioning groove 722 is provided with a first positioning column 723, and the first positioning column 723 is used for sleeving the sleeve 31, so as to ensure that the center hole of the sleeve 31 is not deformed, and facilitate the subsequent smooth press-fitting with the motor shaft 10.

[0050] In one embodiment, in combination with Figure 4 to Figure 6 , the positioning assembly 721 has a positioning notch 724, the loading turntable 720 is provided with a positioning driving member 726, the output end of the positioning driving member 726 is connected with a second positioning column 725, and the second positioning column 725 is used for driving the second positioning column 725 to enter or exit the positioning notch 724. When the positioning assembly 721 is rotated to be connected with any one of the magnetic ring supply mechanism 750, the glue coating mechanism 740, the sleeve loading mechanism 730 and the magnetic ring output mechanism 760, the positioning driving member 726 drives the second positioning column 725 to enter the positioning notch 724, so that the positioning assembly 721 cannot rotate or shake relatively, and the stable work of the magnetic ring supply mechanism 750, the glue coating mechanism 740, the sleeve loading mechanism 730 and the magnetic ring output mechanism 760 is ensured.

[0051] In one embodiment, in combination with Figure 4 and Figure 5The positioning gap 724 is located above the feeding turntable 720, and the positioning driving member 726 is installed below the feeding turntable 720, so that the idle space below the feeding turntable 720 can be fully utilized, and the conflict in space with the upper sleeve feeding mechanism 730, the gluing mechanism 740 and other operation components can be avoided. The feeding turntable 720 has a strip-shaped movable through hole 728, which plays a moving guide role of the second positioning column 725. The bottom end of the second positioning column 725 is connected with the positioning driving member 726, and the top end of the second positioning column 725 penetrates through the movable through hole 728 and is exposed above the feeding turntable 720, and is driven by the positioning driving member 726 to enter and exit the positioning gap 724 along the length direction of the movable through hole 728.

[0052] In some embodiments, in combination with Figure 4 and Figure 6 The feeding turntable 720 has a mounting hole 729, the positioning assembly 721 includes a fixed sleeve 7211, a rotating rod 7212 and a rotating plate 7213, the fixed sleeve 7211 is fixedly installed in the mounting hole 729, the rotating rod 7212 is rotatably installed in the fixed sleeve 7211, the rotating rod 7212 penetrates through the feeding turntable 720, and the rotating plate 7213 is installed at the top of the rotating rod 7212. The rotating plate 7213 is used for carrying the core sleeve 31, so that the core sleeve 31 can be angularly positioned by rotating the rotating plate 7213. Optionally, a positioning bearing 7214 is arranged between the fixed sleeve 7211 and the rotating rod 7212.

[0053] In one embodiment, in combination with Figure 3 and Figure 7 The bottom end of the rotating rod 7212 is provided with a rotating insertion slot 727 penetrating through the radial direction of the rotating rod 7212, the magnetic ring feeding mechanism 700 further includes a radial driving member 773 installed on the first support 710, the radial driving member 773 and the gluing mechanism 740 are arranged adjacent to each other, the output end of the radial driving member 773 is connected with a rotating driving member 772, the output shaft of the rotating driving member 772 is connected with a rotating connecting block 774, the rotating driving member 772 is used for driving the rotating connecting block 774 to rotate around the vertical direction Z, and the radial driving member 773 drives the rotating driving member 772 to move linearly, so that the rotating connecting block 774 enters and exits the rotating insertion slot 727 corresponding to the gluing mechanism 740 of the positioning assembly 721. When the positioning assembly 721 rotates to the side of the gluing mechanism 740, the radial driving member 773 drives the rotating driving member 772 to move in the radial direction, so that the rotating connecting block 774 is embedded in the rotating insertion slot 727, the rotating driving member 772 drives the rotating connecting block 774 and the corresponding positioning assembly 721 to rotate, and at the same time, the gluing mechanism 740 glues the side wall of the core sleeve 31 on the positioning assembly 721, and as the core sleeve 31 rotates, the 360° gluing of the side wall of the core sleeve 31 is realized.

[0054] Specifically, in combination with Figure 3 ,Figure 4 And Figure 7 The magnetic ring feeding mechanism 700 further comprises a positioning push plate 775 installed at the output end of the radial driving member 773, which moves along the same straight line as the output end of the positioning driving member 726 under the driving of the radial driving member 773, so that when the radial driving member 773 drives the rotary driving member 772 and the positioning push plate 775 to move towards the positioning assembly 721, the positioning push plate 775 abuts against the output end of the positioning driving member 726, ensuring that the output end of the positioning driving member 726 is away from the positioning gap 724, and then the rotary connecting block 774 connected with the rotary driving member 772 is embedded in the rotary slot 727, so as to drive the rotating rod 7212 to rotate freely without being hindered by the second positioning column 725.

[0055] In some embodiments, in combination with Figure 3 The magnetic ring feeding mechanism 700 further comprises a glue coating visual detector 771 installed on the first support 710, which is arranged adjacent to the glue coating mechanism 740. The glue coating visual detector 771 detects the quality of the same core sleeve 31 corresponding to the glue coating mechanism 740, so as to visually detect the appearance quality and glue coating quality of the core sleeve 31.

[0056] In some embodiments, in combination with Figure 3 The magnetic ring feeding mechanism 700 further comprises a magnetic ring recycling mechanism 780 installed on the first support 710, which is located at one end of the magnetic ring output mechanism 760 close to the feeding turntable 720. The magnetic ring recycling mechanism 780 is used to recycle the core sleeve 31 with unqualified glue coating quality, so as to avoid the unqualified core sleeve 31 from being pressed and assembled with the motor shaft 10.

[0057] Specifically, the magnetic ring press-fitting machine further comprises a controller electrically connected with the glue coating visual detector 771, the magnetic ring supply mechanism 750 and the magnetic ring recycling mechanism 780 respectively. When the glue coating visual detector 771 visually detects that the core sleeve 31 is unqualified, the controller controls the magnetic ring supply mechanism 750 not to feed the magnetic ring member 32 to the core sleeve 31, and controls the magnetic ring recycling mechanism 780 to recycle the core sleeve 31.

[0058] In some embodiments, in combination with Figure 3The magnetic ring recycling mechanism 780 comprises a recycling box 781, a recycling guide pipe 782 and a recycling driving member 783. The recycling box 781 and the recycling driving member 783 are installed on the first support 710, and the recycling driving member 783 drives the recycling guide pipe 782 to move in a direction perpendicular to the conveying direction of the magnetic ring output mechanism 760, so as to receive the core sleeve 31 and guide the core sleeve 31 to the recycling box 781. When the core sleeve 31 is unqualified, the recycling driving member 783 drives the recycling guide pipe 782 to move and abut against the unqualified core sleeve 31 on the magnetic ring output mechanism 760. The core sleeve 31 falls into the recycling box 781 through the recycling guide pipe 782.

[0059] Optionally, the conveying direction of the magnetic ring output mechanism 760 is the second direction Y, and the moving direction of the recycling guide pipe 782 is the first direction X.

[0060] In some embodiments, in combination with Figure 3 and Figure 8 The sleeve feeding mechanism 730 comprises a first storage rack 731, a first pushing driving member 732, a first pushing plate 733, a first feeding conveying belt 734 and a first double-shaft moving clamp 735. The first storage rack 731 comprises a first bottom plate 736 and a plurality of first storage rods 737 arranged side by side. Optionally, the plurality of first storage rods 737 are distributed at intervals along the second direction Y. Each first storage rod 737 is used for stacking the core sleeve 31. A first gap 738 is formed between the bottom of the first storage rod 737 and the first bottom plate 736. The first gap 738 is greater than the height of a single core sleeve 31 and less than the stacking height of two core sleeves 31. The first gap 738 accurately controls the pushing out of one layer of core sleeves 31 at a time. The first pushing driving member 732 drives the first pushing plate 733 to enter and exit the first gap 738, so as to push the core sleeve 31 to the first feeding conveying belt 734. The two ends of the first feeding conveying belt 734 are respectively connected to the first storage rack 731 and the first double-shaft moving clamp 735. The first double-shaft moving clamp 735 places the core sleeve 31 on the first feeding conveying belt 734 to the feeding turntable 720.

[0061] Based on this, the plurality of first storage rods 737 arranged side by side can form circumferential limiting for the stacked core sleeves 31, and the number of stored core sleeves 31 is large, so that the frequency of replenishment is reduced. The first pushing driving member 732 pushes the first pushing plate 733 into the first gap 738, so as to push the core sleeves 31 falling from the plurality of first storage rods 737 to the first feeding conveying belt 734. Each first storage rod 737 corresponds to one core sleeve 31, so that the plurality of core sleeves 31 arranged side by side are pushed out synchronously. At the end of the first feeding conveying belt 734, the first double-shaft moving clamp 735 carries the core sleeve 31 to the feeding turntable 720.

[0062] Optionally, the first double-shaft moving clamp 735 can move in the vertical direction Z and the first direction X, and the first feeding conveying belt 734 is located on one side of the feeding turntable 720 in the first direction X.

[0067] In some embodiments, referring back to Figure 1 and Figure 9 The press transfer mechanism 300 comprises a first carrying mechanism 410 and a second carrying mechanism 420, which are respectively located at the two ends of the transfer guide 320 in the first direction X. The first carrying mechanism 410 is used to carry the magnetic ring assembly 30 to the carrier block 330, and the second carrying mechanism 420 is used to carry the motor shaft 10 to the carrier block 330.

[0068] Specifically, first, the carrier block 330 moves to the second carrying mechanism 420 in the first direction X under the drive of the transfer drive 310, the second carrying mechanism 420 carries the motor shaft 10 to the carrier block 330, and the carrier block 330 moves the motor shaft 10 to below the press head 250 in the first direction X. Second, the press head 250 and the output end of the jacking drive 230 clamp the motor shaft 10 up and down, the clamping drive 240 is used to clamp the motor shaft 10 horizontally, the output end of the jacking drive 230 is lowered, and the motor shaft 10 is clamped and fixed on the press device 200. Third, the carrier block 330 moves the magnetic ring assembly 30 directly below the press head 250, the output end of the jacking drive 230 and the press head 250 clamp the motor shaft 10 up and down, and are lowered synchronously to press the motor shaft 10 into the magnetic ring assembly 30, realizing the assembly of the motor shaft 10 and the magnetic ring assembly 30.

[0069] In some embodiments, the magnetic ring feeding mechanism 700 is located on one side of the press transfer mechanism 300 in the second direction Y, and the magnetic ring output mechanism 760 is used to deliver the magnetic ring assembly 30 in the second direction Y.

[0070] In one embodiment, the magnetic ring press further comprises a core feeding mechanism 600 for supplying the core piece 20, the core feeding mechanism 600 and the magnetic ring feeding mechanism 700 are located at the same end of the press transfer mechanism 300 in the first direction X and on both sides in the second direction Y. The first carrying mechanism 410 is used to carry the core piece 20 to the carrier block 330. Specifically, the carrier block 330 moves to the first carrying mechanism 410 in the first direction X under the drive of the transfer drive 310, receives the core piece 20 and the magnetic ring assembly 30, and moves the core piece 20 to below the press head 250; then, the output end of the jacking drive 230 is raised to abut against the bottom end of the motor shaft 10 through the first hollow part 214 of the press bottom plate 211, the second hollow part 321 of the transfer guide 320 and the third hollow part 331 of the carrier block 330, and clamps the motor shaft 10 up and down with the press head 250, and is lowered synchronously to press the motor shaft 10 into the core piece 20 below, realizing the assembly of the motor shaft 10 and the core piece 20.

[0071] In some embodiments, in combination with Figure 11, the jacking driving member 230 plays a role of lifting the motor shaft 10 in the press-fitting process to prevent the motor shaft 10 from shaking. The output end of the jacking driving member 230 is connected with a first jacking rod 231, and the end of the first jacking rod 231 is provided with a first positioning cone 232 for positioning the end of the embedded motor shaft 10. The vertex of the first positioning cone 232 can be embedded into the end groove of the motor shaft 10 of different specifications, and the contact with the end of the motor shaft 10 is increased through the conical side surface of the first positioning cone 232, further limiting the displacement of the motor shaft 10 in the horizontal plane.

[0072] In some embodiments, in combination with Figure 11 , the jacking driving member 230 is connected with a hollow first guide cylinder 233, the top end of the first guide cylinder 233 is installed on the press-fitting bottom plate 211, the first guide cylinder 233 and the press-fitting head 250 are coaxially arranged in the vertical direction Z, and the first guide cylinder 233 is used to guide the first jacking rod 231 to pass through the first hollow part 214 in the vertical direction Z. The first guide cylinder 233 directly limits the first jacking rod 231 to move only in the vertical direction Z, completely eliminating the transverse deviation or inclination of the first jacking rod 231 caused by uneven jacking force, too large length-diameter ratio, easy bending or slight deviation of the jacking driving member 230.

[0073] In some embodiments, in combination with Figure 12 and Figure 13 , the press-fitting head 250 includes a press-fitting cylinder body 251 and a second jacking rod 252, the press-fitting cylinder body 251 is installed on the output end of the pressing driving member 220, the second jacking rod 252 is installed on the press-fitting cylinder body 251, and the end of the second jacking rod 252 is provided with a second positioning cone 253 for positioning the end of the embedded motor shaft 10. The vertex of the second positioning cone 253 can be embedded into the end groove of the motor shaft 10 of different specifications, and the contact with the end of the motor shaft 10 is increased through the conical side surface of the second positioning cone 253, further limiting the displacement of the motor shaft 10 in the horizontal plane, realizing automatic centering and eliminating the coaxiality error.

[0074] In one of the embodiments, the press-fitting cylinder body 251 has a positioning sleeve hole 254, the positioning sleeve hole 254 is used to movably sleeve the outer periphery of the end of the motor shaft 10, can form annular constraint from the radial direction of the motor shaft 10, and forcibly correct the motor shaft 10 to the position coaxial with the press-fitting head 250.

[0075] In one of the embodiments, the second jacking rod 252 is installed in the positioning sleeve hole 254, after the motor shaft 10 enters the positioning sleeve hole 254, the circumferential position of the motor shaft 10 is stable, which is beneficial to the alignment of the axis of the second jacking rod 252 with the axis of the motor shaft 10.

[0076] In one of the embodiments, in combination with Figure 12 and Figure 13The pressing head 250 further comprises a lower pressing elastic member 255, one end of which is installed at the bottom of the positioning sleeve hole 254, and the other end of which is installed at the top of the second top rod 252. When the motor shaft 10 end contacts the second top rod 252, the lower pressing elastic member 255 will be compressed with the slight retreat of the second top rod 252, and the impact force during the butt joint will be automatically offset by the elastic force. The lower pressing elastic member 255 can be a spring.

[0077] In one embodiment, the pressing head 250 further comprises a clamping driving member 240, the output end of which is connected with a clamping block 241, and the clamping driving member 240 drives the clamping block 241 to move along the radial direction of the pressing head 250, so as to realize the circumferential limiting of the motor shaft 10 and avoid interfering with the axial force of the motor shaft 10. Figure 13 In addition, the clamping driving member 240 controls the size of the clamping force and adapts to the motor shaft 10 with different outer diameters by controlling the movement distance of the clamping block 241 in the radial direction.

[0078] In one embodiment, the clamping block 241 has a clamping shaft notch 242, and the inner walls of the opposite sides of the clamping shaft notch 242 are used to abut against the outer wall of the motor shaft 10, so as to disperse the clamping force to two contact areas and further limit the rotation and deviation of the motor shaft 10 in the radial direction.

[0079] In one embodiment, the pressing head 250 further comprises a clamping positioning block 260, which is installed at the bottom of the pressing head 250 and has a first accommodating through hole 261 for accommodating the motor shaft 10. Figure 13 The clamping positioning block 260 further has a second accommodating through hole 262, one end of which is communicated with the first accommodating through hole 261, and the other end of which penetrates through the outer side wall of the clamping positioning block 260 along the radial direction of the pressing head 250, and the second accommodating through hole 262 is used for the radial movement of the clamping block 241. The first accommodating through hole 261 limits the circumferential position of the motor shaft 10, further avoids the axis deviation of the motor shaft 10, and ensures that the clamping block 241 does not cause the axis shaking of the motor shaft 10 when clamping the motor shaft 10. The second accommodating through hole 262 provides rigid guidance for the radial movement of the clamping block 241 and improves the movement stability of the clamping block 241. The clamping block 241 is completely hidden in the second accommodating through hole 262, so as to avoid the external interference of the clamping block 241.

[0080] In one embodiment, the number of clamping driving members 240 is two, and the two clamping driving members 240 are oppositely arranged along the radial direction of the pressing head 250, so that the output ends of the two clamping driving members 240 are folded towards each other to form a symmetrical clamping force, thereby avoiding the force deviation of the motor shaft 10.

[0081] In one of the embodiments, the side of the press head 250 has a mounting plane 256, and the clamping drive 240 is mounted on the mounting plane 256, which provides a mounting reference for the clamping drive 240, and the plane contact area is large, which improves the mounting stability of the clamping drive 240.

[0082] In one of the embodiments, the press head 250 is connected with a positioning plug rod 270, which extends downward along the vertical direction Z and is exposed below the press head 250, and the positioning plug rod 270 is used for positioning the plug-in iron core 20, which can prevent the iron core from rotating during the pressing process. Especially when the motor shaft 10 is assembled with multiple iron cores 20, or the iron core 20 and the magnetic ring assembly 30 are continuously pressed, the positioning plug rod 270 keeps the circumferential positioning of the first iron core 20 between multiple pressing processes, which avoids the deviation of the installation angle of the iron core 20.

[0083] In one of the embodiments, the pressing device 200 further comprises a first photoelectric sensor 281, which is mounted on the pressing column 213 and detects the carrier block 330 towards the second direction Y, and the detection height of the first photoelectric sensor 281 is 5mm-50mm higher than the top surface of the carrier block 330. The first photoelectric sensor 281 is used to detect whether the carrier block 330 carries the components to be assembled, which facilitates the confirmation of whether the jacking drive 230 and the pressing drive 220 are started. During the pressing process, metal scraps, dust and other debris may be generated, and if the detection height is less than 5mm, the accumulation of debris may trigger false detection.

[0084] In one of the embodiments, the pressing device 200 further comprises a second photoelectric sensor 282, which is mounted on the pressing column 213 and detects whether the press head 250 is lowered to the preset height towards the second direction Y. When the press head 250 is lowered to the preset height, the second sensor detects the press head 250 and immediately sends a signal to the controller to trigger the press head 250 to stop descending or switch actions, which avoids the damage of the components caused by the excessive downward movement of the press head 250.

[0085] In one of the embodiments, in combination with Figure 1 , the pressing device 200 further comprises a code reader 283, which is mounted on the pressing column 213 and is used to scan the motor shaft 10 located on the carrier block 330.

[0086] In one of the embodiments, in combination with Figure 11The press-fitting device 200 further comprises a pressure sensor 284 mounted on the press-fitting head 250, which is used to detect the press-fitting force of the press-fitting head 250. The pressure sensor 284 can collect the force value changes in real time during the press-fitting process and feed back the data to the controller, so as to ensure that the press-fitting force is always within the preset process interval and guarantee the consistency of the assembly quality. The pressure sensor 284 records the force-displacement curve throughout the process and is bound to store the identity information of the motor shaft 10 (obtained through the code reader 283). The production management personnel can analyze the batch force value curve to optimize the process parameters (such as adjusting the press-fitting speed and correcting the target force value). For example, if it is found that the average press-fitting force of a batch of motor shafts 10 is too high, it can be traced back to the fact that the shaft diameter tolerance is too large, and then feedback is given to the upstream processing link for adjustment.

[0087] In some embodiments, the number of press-fitting conveying mechanisms 300 is at least two, and the at least two press-fitting conveying mechanisms 300 are parallel and spaced apart along the second direction Y to realize parallel operation and greatly improve the production capacity per unit time.

[0088] In one of the embodiments, each press-fitting conveying mechanism 300 corresponds to a pressing driving member 220, a lifting driving member 230, a clamping driving member 240 and a press-fitting head 250. When each press-fitting conveying mechanism 300 is matched with an independent press-fitting head 250, the plurality of press-fitting conveying mechanisms 300 realize synchronous independent operation without interference. The pressing driving member 220, the lifting driving member 230, the clamping driving member 240 and the press-fitting head 250 share one press-fitting support 210, which reduces the volume of the press-fitting device 200 and improves the integrity and modularity of the press-fitting device 200.

[0089] Specifically, the number of press-fitting conveying mechanisms 300 is two, and the two ends of the two press-fitting conveying mechanisms 300 are aligned in the first direction X. Correspondingly, the number of pressing driving members 220, lifting driving members 230, clamping driving members 240 and press-fitting heads 250 is two. The first conveying mechanism 410 and the second conveying mechanism 420 can convey two components at the same time, i.e., the first conveying mechanism 410 simultaneously grabs two core members 20 and places them on the carrying blocks 330 of the two press-fitting conveying mechanisms 300, simultaneously grabs two magnetic ring assemblies 30 and places them on the carrying blocks 330 of the two press-fitting conveying mechanisms 300, and the second conveying mechanism 420 simultaneously grabs two motor shafts 10 and places them on the carrying blocks 330 of the two press-fitting conveying mechanisms 300. Alternatively, the two pressing driving members 220, lifting driving members 230 and clamping driving members 240 move synchronously to avoid the problem of uneven wear of the press-fitting device 200 caused by long-term bearing of larger load by a single station.

[0090] In some embodiments, in combination with Figure 9 , Figure 14 and Figure 15The carrying block 330 comprises a first conveying block 340 and a second conveying block 350, the first conveying block 340 and the second conveying block 350 are sequentially arranged along the first direction X, the first conveying block 340 is closer to the first conveying mechanism 410 than the second conveying block 350, the first conveying block 340 is used for placing the magnetic ring assembly 30 and the at least two core pieces 20, and the first conveying block 340 is provided with at least two core positioning pin groups 341 and one magnetic ring positioning hole 342 which are sequentially and separately arranged along the first direction X. The first conveying block 340 and the second conveying block 350 both have the third hollow part 331.

[0091] Therefore, the first conveying mechanism 410, the press-fitting device 200 and the second conveying mechanism 420 are sequentially arranged along the first direction X, the first conveying block 340 is used for being docked with the first conveying mechanism 410, and the second conveying block 350 is used for being docked with the second conveying mechanism 420, so that the sliding stroke of the carrying block 330 is shortened, and the work efficiency is improved. The core positioning pin groups 341 prevent the core pieces 20 from rotating and deviating during the movement of the carrying block 330, and the magnetic ring positioning hole 342 realizes the accurate positioning of the magnetic ring assembly 30 on the first conveying block 340.

[0092] Specifically, the core positioning pin groups 341 are two cylindrical pins which are linearly and spacedly arranged.

[0093] In one of the embodiments, the magnetic ring positioning hole 342 is located at the end of the first conveying block 340 which is close to the first conveying mechanism 410, and matches the assembly sequence of the rotor assembly. Therefore, the first conveying block 340 is moved along the first direction X to be close to the press-fitting head 250, and the plurality of core pieces 20 are sequentially assembled to the motor shaft 10, and finally the magnetic ring assembly 30 is assembled to the motor shaft 10.

[0094] In one of the embodiments, all the core positioning pin groups 341 are sequentially arranged to be deflected around the vertical direction Z by a preset angle, so that the plurality of core pieces 20 are assembled to the same motor shaft 10 by the preset angle. In one of the embodiments, the second conveying block 350 is used for placing the motor shaft 10, and the motor shaft 10 is separately fed with the core pieces 20.

[0095] In some embodiments, the conveying drive 310 comprises a first drive 311 and a second drive 312, the first drive 311 is used for driving the first conveying block 340, and the second drive 312 is used for driving the second conveying block 350. Independent driving allows the first conveying block 340 and the second conveying block 350 to move in parallel, thereby improving the press-fitting efficiency.

[0096] In one of the embodiments, the first conveying block 340 is provided with a plurality of magnetic ring positioning holes 342 which are sequentially and separately arranged along the first direction X, and the second conveying block 350 is provided with a plurality of magnetic ring positioning holes 342 which are sequentially and separately arranged along the first direction X. Figure 14The first driving member 311 and the second driving member 312 are respectively located on opposite sides of the conveying guide 320 in the second direction Y. On the one hand, the first driving member 311 and the second driving member 312 are respectively located on opposite sides of the conveying guide 320, and the force generated during driving can be offset in the second direction Y, so that the conveying guide 320 is balanced as a whole without additional eccentric torque. On the other hand, the design of being respectively located on opposite sides can disperse the installation space of the first driving member 311 and the second driving member 312 to the left and right sides of the conveying guide 320, and fully utilize the space in the second direction Y.

[0097] In one of the embodiments, in combination with Figure 14 The conveying guide 320 is a sliding rail, the conveying driving member 310 drives the carrier block 330 to slide in the first direction X, the conveying guide 320 is stationary, and the second hollow part 321 is stationary and overlaps the first hollow part 214 vertically. It can be understood that in other embodiments, the conveying guide 320 is a conveying belt, the conveying driving member 310 drives the conveying belt to rotate, thereby driving the carrier block 330 to move in the first direction X, the second hollow part 321 of the conveying guide 320 and the third hollow part 331 of the carrier block 330 overlap vertically and move together in the first direction X to overlap the first hollow part 214 vertically, thereby allowing the output end of the jacking driving member 230 to pass through.

[0098] In some embodiments, in combination with Figure 1 and Figure 9 The magnetic ring press fitting machine comprises a shaft feeding mechanism 510 mounted on the frame 100, and the shaft feeding mechanism 510 is used for conveying a shaft insertion plate 520 in the second direction Y. The shaft insertion plate 520 is provided with a plurality of motor shafts 10, which realizes batch centralized feeding and greatly improves the feeding efficiency, directly solves the pain points of low single feeding efficiency and easy bumping. The shaft feeding mechanism 510 is located on one side of the press fitting conveying mechanism 300 in the second direction Y, fully utilizes the space in the second direction Y, reduces the size of the equipment in the first direction X, and compresses the overall land occupation of the equipment.

[0099] Optionally, the magnetic ring press fitting machine comprises a shaft material vehicle 530, which is connected to the shaft feeding mechanism 510 on the side away from the press fitting conveying mechanism 300, avoids interference with press fitting, and is away from the press fitting working area, which is beneficial to protecting the feeding safety.

[0100] In some embodiments, in combination with Figure 1 and Figure 9The shaft feeding mechanism 510, the second carrying mechanism 420 and the press-fitting conveying mechanism 300 are sequentially and spacedly distributed along the second direction Y. The second carrying mechanism 420 directly grabs the motor shaft 10 at the output end of the shaft feeding mechanism 510 without adjusting the grabbing direction, translates from the shaft feeding mechanism 510 to the press-fitting conveying mechanism 300 along the second direction Y, and only needs to move a short distance after grabbing to place the motor shaft 10 on the carrying block 330 of the press-fitting conveying mechanism 300, thereby improving work efficiency.

[0101] In one of the embodiments, the magnetic ring press-fitting machine further comprises a first visual detector 540 installed on the rack 100, the first visual detector 540 is located between the shaft feeding mechanism 510 and the press-fitting conveying mechanism 300, and the first visual detector 540 is used to detect the appearance quality of the motor shaft 10. Based on this, the motor shaft 10 with appearance defects is intercepted in advance by the first visual detector 540 to avoid defective products flowing into subsequent processes and to ensure assembly quality. Moreover, the first visual detector 540 replaces manual visual detection to improve detection efficiency and consistency and adapt to automatic rhythm. The first visual detector 540 is located between the shaft feeding mechanism 510 and the press-fitting conveying mechanism 300, and the second carrying mechanism 420 needs to move to the press-fitting conveying mechanism 300 after grabbing the motor shaft 10 from the shaft feeding mechanism 510. The moving path passes through the detection area of the first visual detector 540, and the first visual detector 540 synchronously completes shooting and analysis to improve detection efficiency.

[0102] In one of the embodiments, in combination with Figure 1 The magnetic ring press-fitting machine further comprises a first recovery mechanism 550 installed on the rack 100, the movement track of the second carrying mechanism 420 passes through the first recovery mechanism 550, and the detection range of the first visual detector 540 covers the upper side of the first recovery mechanism 550. Based on this, the second carrying mechanism 420 needs to move to the press-fitting conveying mechanism 300 after grabbing the motor shaft 10 from the shaft feeding mechanism 510, and must pass through the first recovery mechanism 550. At this time, the motor shaft 10 is detected by the first visual detector 540, if qualified, it continues to move to the press-fitting conveying mechanism 300; if not qualified, it is placed in the first recovery mechanism 550 and returns to grab the next motor shaft 10, thereby improving the efficiency of feeding and detection.

[0103] In one of the embodiments, in combination with Figure 1, the first visual detector 540 and the first recycling mechanism 550 are distributed along the first direction X. The movement trajectory of the second carrying mechanism 420 needs to connect the taking shaft, detection, feeding of the qualified shaft to the pressing assembly or feeding of the unqualified shaft to the recycling. If the first visual detector 540 and the first recycling mechanism 550 are distributed along the second direction Y, the second carrying mechanism 420 needs to stay continuously twice in the second direction Y, that is, first stay below the first visual detector 540 for detection, and then stay above the first recycling mechanism 550 for placing the unqualified product, thereby increasing the loading time cost. When the first visual detector 540 and the first recycling mechanism 550 are distributed along the first direction X, the second carrying mechanism 420 only needs to stay once between the first visual detector 540 and the first recycling mechanism 550. If the detection is qualified, the second carrying mechanism 420 continues to move, otherwise, the motor shaft 10 is recycled, the action path is more concise, and the beat conflict with other mechanisms is avoided.

[0104] In one of the embodiments, the magnetic ring pressing machine further comprises a first visual detector 540 and a first recycling mechanism 550. Figure 1 , the magnetic ring pressing machine further comprises a marking mechanism 560 installed on the rack 100, and the marking mechanism 560 is used for marking the motor shaft 10 to realize information management in the production process.

[0105] In one of the embodiments, the marking mechanism 560 is located between the shaft loading mechanism 510 and the pressing conveying mechanism 300. The marking action is embedded in the transfer gap, and a separate marking movement path does not need to be added for marking, thereby improving the operation efficiency.

[0106] Specifically, the marking mechanism 560 is located between the first visual detector 540 and the pressing conveying mechanism 300, and only the motor shaft 10 that passes the visual detection is marked. The unqualified shaft is directly fed to the first recycling mechanism 550 by the second carrying mechanism 420, thereby avoiding invalid marking (waste of marking materials / time and the need to clean the marked unqualified product during subsequent recycling) of the unqualified motor shaft 10, and improving the operation efficiency.

[0107] In some embodiments, the magnetic ring pressing machine further comprises a first visual detector 540 and a first recycling mechanism 550. Figure 1 , the magnetic ring pressing machine further comprises a discharging mechanism 800 installed on the rack 100, and the discharging mechanism 800 and the shaft loading mechanism 510 are located on the same end of the pressing conveying mechanism 300 in the first direction X. The discharging mechanism 800 and the shaft loading mechanism 510 are located on opposite sides of the pressing conveying mechanism 300 in the second direction Y. The first aspect is to avoid increasing the size of the first direction X. The second aspect is to form a symmetrical layout of single-side feeding and single-side discharging, thereby avoiding space congestion caused by stacking of different mechanisms on the same side. The third aspect is that the other end of the pressing conveying mechanism 300 needs to load the magnetic ring assembly 30 and the core member 20, and therefore the discharging mechanism 800 is placed on the same end of the shaft loading mechanism 510, thereby making the layout more uniform.

[0108] In some embodiments, the magnetic ring pressing machine further comprises a first visual detector 540 and a first recycling mechanism 550. Figure 1The magnetic ring press machine also includes a core feeding mechanism 600 installed on the frame 100, which supplies core components 20 along the second direction Y.

[0109] In one embodiment, combined with Figure 2 The magnetic ring feeding mechanism 700, the pressing and conveying mechanism 300, and the iron core feeding mechanism 600 are distributed at intervals along the second direction Y. That is, the feeding of the iron core 20 and the feeding of the magnetic ring assembly 30 are respectively on both sides of the pressing and conveying mechanism 300, avoiding feeding interference, reducing the risk of mechanism collision, and the distribution along the second direction Y can maximize the use of the linear space of the frame 100 and reduce redundant footprint.

[0110] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
