The motor assembly equipment of the present invention can automatically complete the processes of fan blade feeding, rotor pressing, end cover pressing, screw fixing, accessory installation, material sorting and stacking, etc., and has the advantages of simple structure, high efficiency and high assembly qualification rate.

[0020] 2. The barrel positioning unit of the present invention is used to position the barrel, and the end cap positioning pin of the end cap positioning unit is used to position the end cap circumferentially. When the end cap is press-fitted, the end cap is pressed into the barrel under the guidance of the end cap positioning pin, thereby achieving precise assembly.

When the fan blade is placed into the fan blade positioning cavity, the shaft mounting part, the blade, and the reinforcing ribs enter the corresponding clearance portions, which ensures that the fan blade body can fully contact the bottom surface of the barrel positioning seat. When the rotor and fan blade are press-fitted, the force-bearing area of ​​the fan blade is increased, effectively preventing its deformation.

[0022] 4. The pressing device of the present invention realizes the multi-stage pressing of the rotor and the end cover through a pressing drive component. First, the rotor is pressed with the barrel and the fan blade through the rotor pressing mechanism, and then the end cover is pressed with the rotor and the barrel through the end cover pressing mechanism, thereby improving the pressing quality of the motor.

[0054] The present invention will be further described below with reference to specific embodiments:

[0055] An electric motor assembly device for automatically assembling electric motors 1.

[0056] like Figure 1-2 As shown, the motor 1 includes a fan blade 11, a casing 12, a rotor 13, and an end cover 14. Bearings are installed at both the front and rear ends of the rotor 13. During installation, the rear end of the rotor 13 needs to pass through the end face of the casing 12 and the fan blade 11, and the rear bearing is installed on the end face of the casing 12. The front end of the rotor 13 needs to be fitted with the end cover 14, and the front bearing is installed on the end cover 14. Additionally, depending on the application of the motor, appropriate accessories need to be selected and installed at the front end of the rotor 13. These accessories are generally a pulley 15 or a motor nut.

[0057] The fan blade 11 includes a disc-shaped fan blade body 111, blades 113 circumferentially arranged on the fan blade body 111, a shaft mounting portion 112 disposed in the middle of the fan blade body 111 and used for mounting at one end of the rotor 13, and a reinforcing rib 114 disposed between the shaft mounting portion 112 and two symmetrical blades 113.

[0058] The front end sidewall of the barrel 12 is provided with at least one circumferential positioning protrusion 121, and at least one threaded hole is provided on the circumferential positioning protrusion 121. In this embodiment, three circumferential positioning protrusions 121 are provided, and each circumferential positioning protrusion 121 is provided with a threaded hole.

[0059] The end cap 14 has mounting protrusions around its perimeter corresponding to the circumferential positioning protrusions 121. The mounting protrusions have fixing holes 141 corresponding to the threaded holes. The fixing holes 141 are through holes. After the end cap 14 is pressed onto the barrel 12, the screw passes through the fixing holes 141 and is fixedly connected to the threaded holes, thus achieving a fixed installation of the two.

[0060] like Figure 3-4 As shown, a motor assembly equipment includes a main frame 2, several workpiece positioning devices 9, a station switching device 3, several processing stations, a fan blade feeding device 4, a pressing device 5, a screw fastening device 6, an accessory installation device 7, and a material discharge and stacking device 8.

[0061] The main frame 2 is equipped with a workstation switching device 3, which includes a turntable mounted on the main frame 2 and a turntable motor that drives the turntable to rotate. The turntable has several installation stations arranged circumferentially, and each installation station is equipped with a corresponding workpiece positioning device 9 for placing motor components. This embodiment has eight installation stations, and the turntable rotates 45 degrees each time it is driven by the turntable motor.

[0062] The processing stations are located on one side of the corresponding workpiece positioning device 9 as needed. In this embodiment, they are divided into the first loading station, the second loading station, the pressing station, the fastening station, the first accessory installation station for assembling the pulley 15, the second accessory installation station for assembling the motor nut, the inspection station, and the unloading station in sequence according to the processing order.

[0063] The first loading station is equipped with a fan blade loading device 4, which is used to transport the fan blade 11 to the corresponding workpiece positioning device 9.

[0064] The second loading station is a manual loading station. The worker stands at the second loading station and places the barrel 12, the rotor 13 with bearings and the end cover 14 into the workpiece positioning device 9 with the fan blades 11 installed in sequence.

[0065] The pressing station is equipped with a pressing device 5, which is used to press the fan blade 11, the barrel 12, the rotor 13, and the end cover 14 together.

[0066] The fastening station is equipped with a screw fastening device 6, which fixes the end cover 1 to the barrel 12 by screws.

[0067] The accessory installation device 7 is installed at the accessory installation station and is used to assemble the pulley 15 or the motor nut. To increase equipment versatility, this embodiment provides two accessory installation stations: a first station for assembling the pulley 15 and a second station for assembling the motor nut. Each station has a corresponding accessory installation device 7, and the user can select the appropriate device 7 as needed.

[0068] The inspection station can be used to manually check whether the motor is assembled correctly, or it can be used to directly inspect it with testing equipment.

[0069] The unloading station is equipped with a material unloading and stacking device 8, which is used for unloading motors 1, transferring qualified motors 1 to qualified area 100 for stacking, and transferring unqualified motors 1 to unqualified area 200 for stacking.

[0070] Workpiece positioning device

[0071] The workpiece positioning device 9 is used to facilitate the positioning and installation of the fan blade 11, barrel 12, rotor 13 and end cover 14 of the motor 1.

[0072] like Figure 5-7 As shown, the workpiece positioning device 9 includes a tooling base plate 91, a barrel positioning unit 92, and an end cap positioning unit 93.

[0073] The tooling base plate 91 is mounted on the turntable of the workstation switching device.

[0074] The barrel positioning unit 92 is mounted on the tooling base plate 91 and is mainly used to position the barrel 12 and the fan blade 11.

[0075] like Figure 6 As shown, the barrel positioning unit 92 has a barrel positioning seat 921, a plurality of barrel positioning pins 922, a circumferential positioning component 923, and a fan blade positioning pin 925.

[0076] The barrel positioning seat 921 is disc-shaped. Designed according to the dimensions of the barrel, it is first positioned on the tooling base plate 91 by two positioning pins 94, and then fixed by a seat fixing member 95, preferably a screw. The tooling base plate 91 is provided with a first pin hole corresponding to the positioning pin 94 and a threaded fixing hole corresponding to the seat fixing member 95, which facilitates the installation of the barrel positioning seat 921.

[0077] like Figure 7As shown, the internal cavity of the barrel positioning seat 921 is provided with a fan blade positioning cavity 924, and the fan blade positioning cavity 924 is provided with a plurality of fan blade positioning pins 925 for positioning the fan blade 11. In this embodiment, two fan blade positioning pins 925 are provided, and two fan blade positioning holes 115 are provided on the fan blade body 111. The fan blade 11 is inserted into the fan blade positioning pins 925 in the fan blade positioning cavity 924 to determine its position.

[0078] Preferably, the fan blade positioning cavity 924 is provided with a first clearance portion 9241 for accommodating the shaft mounting portion 112 of the fan blade 11, a plurality of second clearance portions 9242 for accommodating the blades 113 of the fan blade 11, and a third clearance portion 9243 for accommodating the reinforcing ribs 114 of the fan blade 11. The third clearance portion 9243 is disposed between the first clearance portion 9241 and the two symmetrical second clearance portions 9242. Since the assembled fan blade 11 has a shaft mounting portion 112, blades 113, and reinforcing ribs 114 protruding to the same side, this embodiment provides corresponding clearance portions. The clearance portions are all deep holes or grooves of corresponding shapes. When the fan blade 11 is placed into the fan blade positioning cavity 924, the shaft mounting portion 112, blades 113, and reinforcing ribs 114 enter the corresponding clearance portions. This ensures that the fan blade body 111 of the fan blade 11 can fully contact the bottom surface of the barrel positioning seat 921. When the rotor 13 and the fan blade 11 are press-fitted, the force-bearing area of ​​the fan blade 11 is increased, effectively preventing its deformation.

[0079] According to the inner / outer diameter of the barrel 12, second pin holes are distributed along the circumferential direction on the barrel positioning seat 921, and barrel positioning pins 922 are provided on the second pin holes. In this embodiment, three barrel positioning pins 922 are provided, each spaced 120 degrees apart, and are arranged on the barrel positioning seat 921 according to the outer diameter of the barrel 12.

[0080] Two circumferential positioning members 923 are provided, each with a strip-shaped hole, and are fixed to the barrel positioning seat 921 by screws. The space between the two circumferential positioning members 923 is used to accommodate any one of the circumferential positioning protrusions 121 of the barrel 12, for positioning the circumferential position of the barrel 12. In this embodiment, the gap between the two circumferential positioning members 923 can be adjusted by the strip-shaped hole to accommodate circumferential positioning protrusions 121 of different widths and adapt to different barrel models.

[0081] Preferably, an end cap support 926 extends between two adjacent second clearance portions 9242. The end cap support 926 is an arc-shaped boss, and multiple end cap support portions 926 are provided, all with flush upper surfaces. The upper surface of the end cap support 926 and the upper surface of the fan blade positioning pin 925 contact the end face of the barrel 12 together. In this embodiment, the end face of the barrel 12 is flat, therefore, the upper surface of the end cap support 926 and the upper surface of the fan blade positioning pin 925 are flush. When one end of the barrel 12 is installed on the barrel positioning seat 921, the end cap support 926 supports the outer edge of the end face of the barrel 12, and the fan blade positioning pin 925 supports the center of the end face of the barrel 12. During rotor pressing, the center of the end face of the barrel 12 is supported by the fan blade positioning pin 925, and the edge of the end face of the barrel 12 is supported by the end cap support 926, which can effectively prevent deformation of the end face of the barrel 12.

[0082] Burrs are prone to appear on the outer ring of the end face of the barrel 12. In order to prevent the burrs from affecting the positioning, the outer ring of the end cover support 926 is also provided with a flanged relief part 927. The flanged relief part 927 can be a complete annular groove, an annular groove composed of several arc grooves, or an irregular groove that can accommodate the outer ring of the end face of the barrel 12.

[0083] like Figure 5 As shown, the end cap positioning unit 93 is disposed on one side of the barrel positioning unit 92 and is used for circumferential positioning of the end cap 14. When the end cap 14 is press-fitted, the end cap positioning unit 93 can guide the end cap 14 so that its fixing hole 141 can correspond to the threaded hole of the barrel 12.

[0084] The end cap positioning unit 93 includes an end cap positioning seat 933 fixed on the tooling base plate 91, an end cap positioning frame 931, and an end cap positioning pin 932 vertically arranged on the end cap positioning frame 931. The end cap positioning frame 931 can be movably arranged on the end cap positioning seat 933 and its height can be adjusted to easily adapt to barrels of different heights.

[0085] After the barrel 12 and rotor 13 are installed on the workpiece positioning device 9, the end cover 14 is loaded. At this time, the guide hole 142 of the end cover 14 is aligned with the end cover positioning pin 932 and inserted, and then placed on the barrel 12 and rotor 13.

[0086] In this embodiment, the positions of the end cap positioning pin 932 and the barrel positioning seat 921 are designed according to the size relationship of the motor 1. When the end cap 14 moves down along the end cap positioning pin 932 and is pressed into the barrel 12, it can be ensured that the fixing hole 141 of the end cap 14 and the threaded hole of the barrel 12 correspond, which facilitates the tightening and fixing of the screws.

[0087] Preferably, the end cap positioning frame 931 has a vertical positioning rod portion and a horizontal pin mounting portion. One end of the pin mounting portion is fixed to one end of the positioning rod portion, and the other end is fixed to the end cap positioning pin 932. The end cap positioning pin 932 is vertically arranged, and its lower end is fixed to the pin mounting portion. Generally, the height of the pin mounting portion is lower than the height of the circumferential positioning protrusion 121 of the barrel 12. In this way, when the end cap 14 is press-fitted, the end cap positioning unit 93 does not need to move up and down. The end cap 14 moves on the end cap positioning pin 932 and is press-fitted by the length of the end cap positioning pin 932. In addition, the end cap 14 in this embodiment is provided with a separate guide hole 142 for mounting the end cap positioning pin 932, so it will not affect the assembly of the screws. After assembly, it is only necessary to move the motor 1 upward to disengage from the end cap positioning pin 932 before unloading.

[0088] The positioning rod has several first adjustment holes 9311 spaced apart. After the adjusting fastener passes through the corresponding first adjustment hole 9311, it fixes the end cap positioning frame 931 onto the end cap positioning seat 933. The height of the end cap positioning frame 931 can be adjusted by selecting different first adjustment holes 9311 through the adjusting fastener.

[0089] In addition, the end cap positioning seat 933 has a second adjustment hole 9331 vertically opened on both sides of the opposite side wall. The second adjustment hole 9331 is a long strip hole. The adjustment fixing component is a bolt and a fixing nut. The bolt passes through the second adjustment hole 9331 and the first adjustment hole 9311 in sequence to realize the fixed connection between the end cap positioning frame 931 and the end cap positioning seat 933.

[0090] [Fan-blade feeding device]

[0091] like Figure 8-9 As shown, the fan blade feeding device 4 includes a feeding frame, a fan blade unloading unit for stacking fan blades 11, and a fan blade feeding unit for transporting fan blades 11. The fan blade feeding unit is used to transport the fan blades 11 on the fan blade unloading unit to the corresponding workpiece positioning device 9.

[0092] The fan blade feeding unit includes a feeding rotary disk 47 disposed on the feeding frame 46, a feeding motor 48 that drives the feeding rotary disk 47 to rotate, and a plurality of feeding rods 49 disposed on the feeding rotary disk 47, wherein a plurality of fan blades 11 are stacked on the feeding rods 49 in sequence.

[0093] The fan blade feeding unit includes a fan blade feeding support frame 41 mounted on the main frame 2, a first translation component 42 disposed on the fan blade feeding support frame 41, at least one first lifting component 43 disposed on the first translation component 42, and a fan blade suction cup component 44 disposed on the first lifting component 43 for adsorbing the fan blade 11.

[0094] Specifically, the first translation component 42 includes a first translation slide rail 421 horizontally arranged on the fan blade loading support frame 41, a first translation plate 422 arranged on the first translation slide rail 421, and a first translation drive 423 for driving the first translation plate 422 to move. The first translation drive is preferably a cylinder.

[0095] The first lifting component 43 is the first lifting drive component. In this embodiment, two are arranged side by side on the first translation plate 422. The first lifting drive component is provided with the fan blade suction cup component 44. The first lifting drive component is preferably a cylinder.

[0096] like Figure 9 As shown, the fan blade position calibration unit 45 includes a calibration frame 451, a calibration rotation drive 452, a calibration disc 453, and a calibration rod 454.

[0097] The calibration frame 451 is mounted on the main frame 2. The calibration rotation drive 452 is disposed on the calibration frame 451, preferably a rotary cylinder. The calibration disk 453 is used to hold the fan blade 11, which is rotated by the calibration rotation drive 452. The bottom of the calibration disk 453 is provided with a through groove 4531. The calibration rod 454 is fixed on the calibration frame 451 by the calibration rod mounting bracket 455 and passes through the through groove 4531 and is disposed inside the calibration disk 453.

[0098] When the fan blade 11 is placed in the calibration disc 453, it can rotate with the calibration disc 453. The through groove 4531 can be annular or C-shaped, and its diameter is larger than the outer diameter of the shaft mounting part 112 and smaller than the distance from the inner end of the blade 113 to the axis. At this time, when the fan blade 11 rotates, the calibration rod 454 will not touch the blade 113 and the shaft mounting part 112. At the same time, the upper end of the calibration rod 454 is lower than the placed fan blade body 111 but higher than the lowest edge of the reinforcing rib 114.

[0099] When the fan blade 11 rotates with the calibration disc 453, it stops rotating after the reinforcing rib 114 touches the calibration rod 454, at which point the fan blade 11 is calibrated to the preset angle. Since the two reinforcing ribs 114 of the fan blade 11 in this embodiment are symmetrically arranged, the preset angle can be calibrated when either reinforcing rib 114 is blocked by the calibration rod 454.

[0100] In addition, the distance between the two first lifting components 43 is equal to the distance from the fan blade feeding position of the fan blade feeding unit to the calibration plate 453, and also equal to the distance between the calibration plate 453 and the corresponding fan blade positioning cavity 924.

[0101] The two fan blade suction cup assemblies 44 have a first loading position and a second loading position. At the first loading position, the left fan blade suction cup assembly 44 picks up the fan blade 11 already loaded, and the right fan blade suction cup assembly 44 picks up the calibrated fan blade 11. Then, it moves to the second loading position. At this time, the left fan blade suction cup assembly 44 places the fan blade 11 onto the fan blade position calibration unit 45, and the right fan blade suction cup assembly 44 places the fan blade 11 into the fan blade positioning cavity 924. Then it returns to the first loading position, and the cycle repeats. Compared to the case of a single first lifting assembly 43, this embodiment can increase the loading efficiency.

Pressure fitting device

[0103] The pressing device 5 is used for pressing the fan blade 11, the barrel 12, the rotor 13 and the end cover 14.

[0104] like Figure 10-11 As shown, the pressing device 5 includes a pressing frame 51, a pressing drive component 52, a pressing frame 53, a rotor pressing mechanism 54, an end cap pressing mechanism 55, and a support unit 56.

[0105] The pressing frame 51 is installed on the main frame 2. The pressing frame 51 includes a bottom plate, left and right side plates, a back plate and a top plate, which together form a frame structure with an opening at the front.

[0106] The press-fitting drive component 52 can be an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder. It is located at the upper end of the press-fitting frame 51, i.e., the top plate, and is used to generate press-fitting power.

[0107] The pressing frame 53 includes four pressing guide posts 534 movably mounted on the top plate, an upper pressing plate 532 mounted on the upper end of the pressing guide posts 534, and a lower pressing plate 533 mounted on the lower end of the pressing guide posts 534. The upper pressing plate 532 is a hollow plate and is located on the outer periphery of the pressing drive member 52. It will not be interfered with by the pressing drive member 52 during movement, and can control the height of the pressing device 5. The lower pressing plate 533 is connected to the telescopic end of the pressing drive member 52, and the pressing frame 53 is raised and lowered through the pressing drive member 52.

[0108] In order to improve the quality of pressing, the pressing device 5 in this embodiment realizes the pressing of rotor 13 and end cover 14 in stages through a pressing drive 52. First, the pressing of rotor 13 with barrel 12 and fan blade 11 is performed, and then the pressing of end cover 14 with rotor 13 and barrel 12 is performed.

[0109] The end cap pressing mechanism 55 is mounted on the pressing frame 53 and located on the outer periphery of the rotor pressing mechanism 54.

[0110] Specifically, the end cap pressing mechanism 55 includes an end cap pressing plate 551, a plurality of columns 552, and an end cap pressing core 553.

[0111] The end cap pressing plate 551 is fixed on the pressing frame 53 by several columns 552. The end cap pressing plate 551 has a core mounting hole inside, and the end cap core 553 is fixed in the core mounting hole. The shape of the end cap core 553 is adapted to the outer ring of the end cap 14. The end cap core 553 is made of wear-resistant material and its shape is C-shaped or ring-shaped.

[0112] In addition, the end cap pressing core 553 and the end cap pressing plate 55 can be integrated or separate, preferably separate. When the end cap pressing core 553 is worn, it is convenient to quickly replace the end cap pressing core 553 and reduce costs.

[0113] like Figure 12 As shown, the rotor pressing mechanism 54 is located in the middle of the pressing lower plate 533 of the pressing frame 53, and includes a rotor pressing sleeve 541 for rotor guidance, a rotor pressing core 542 for rotor pressing, and a pressing switching unit.

[0114] The rotor pressing sleeve 541 is fixed to the lower end face of the pressing lower plate 533 of the pressing frame 53, and has an inlet 5414; the rotor pressing core 542 is movably disposed inside the rotor pressing sleeve 541 by the pressing spring 543, and the pressing switching unit is used to lock / release the positional relationship between the rotor pressing core 542 and the rotor pressing sleeve 541.

[0115] Specifically, the press-fit switching unit includes a switching drive component 544 and a blocking component 545. The switching drive component 544 is fixed on the press-fit frame 53, and is preferably a cylinder. The blocking component 545 is cuboid and connected to the switching drive component 544 to achieve horizontal movement. The rotor press-fit sleeve 541 has a blocking hole 5413 in the middle for the blocking component 545 to be inserted.

[0116] When the blocking member 545 is inserted into the blocking hole 5413, and the pressing drive member 52 drives the pressing frame 53 to press down, the upper end of the rotor 13 first extends into the inlet 5414 and abuts against the rotor core 542. The rotor core 542 is blocked by the blocking member 545, that is, the rotor core 542 is locked inside the rotor pressing sleeve 541. At this time, the pressing of the rotor 13 with the barrel 12 and the fan blade 11 can be realized. At this time, the end cover pressing mechanism 55 has not yet acted on the end cover 14. Subsequently, after the blocking member 545 leaves the blocking hole 5413, when the pressing drive member 52 drives the pressing frame 53 to continue pressing down, the rotor core 542 can move inside the rotor pressing sleeve 541 and will no longer exert downward pressure on the rotor 13. At this time, the end cover pressing mechanism 55 acts on the end cover 14 to press down, completing the pressing with the rotor 13 and the barrel 12.

[0117] Specifically, the rotor pressing sleeve 541 includes an upper pressing sleeve 5411 with the blocking hole 5413 and a lower pressing sleeve 5412 with the inlet 5414, which are fixedly connected by screws. The upper pressing sleeve 5411 is fixed on the lower pressing plate 533. The rotor core 542 has a pressing rod portion 5421 and a pressing portion 5422. The outer diameter of the pressing portion 5422 is larger than the outer diameter of the pressing rod portion 5421, that is, the cross-section of the rotor core 542 is inverted T-shaped.

[0118] The upper press-fit sleeve 5411 has an upper through hole 5415 adapted to the press rod portion 5421, and the lower press-fit sleeve 5412 has a lower through hole 5416 adapted to the press-fit portion 5422. The upper through hole 5415 and the lower through hole 5416 are coaxially arranged. The diameter of the upper through hole 5415 is smaller than the diameter of the lower through hole 5416. The press-fit spring 543 is fitted onto the press rod portion 5421 and abuts against the press-fit portion 5422 and the upper press-fit sleeve 5411. Under normal conditions, the press-fit spring 543 provides a force to the rotor core 542 near the inlet 5414.

[0119] Furthermore, the upper end of the rotor core 542 generally does not disengage from the upper through hole 5415. That is, when the rotor core 542 and the rotor pressing sleeve 541 are locked, a portion of the upper end of the rotor core 542 is inside the upper through hole 5415 and abuts against the blocking member 545, facilitating its movement within the upper through hole 5415 of the upper pressing sleeve 5411 after subsequent unlocking, without causing jamming. At this time, the lower end of the rotor core 542 abuts precisely at the inlet 5414 of the lower pressing sleeve 5412, effectively controlling the length of the rotor pressing sleeve 541.

[0120] During the press-fitting of rotor 13, the blocking member 545 needs to transmit downward pressure. To increase stability, the blocking hole 5413 radially penetrates the upper press-fitting sleeve 5411 and the upper through hole 5415. When it is necessary to fix the rotor core 542, the blocking member 545 is horizontally inserted between the entire upper press-fitting sleeve 5411. Both ends of the blocking member 545 are blocked by the upper press-fitting sleeve 5411. During the press-fitting of rotor 13, the blocking member 545 is not easily deformed or displaced, effectively ensuring the stable operation of rotor core 542.

[0121] Preferably, the pressing frame 53 is provided with a pressing core clearance hole 531 for the rotor pressing core 542, which facilitates the movement of the rotor pressing core 542. This reduces the length of the rotor pressing sleeve 541 and makes the structure more compact.

[0122] like Figure 13 As shown, the pressing device 5 also includes a support unit 56 located below the workpiece positioning device 9, which has a support base 561, a support core 562, a pusher 563 and a pusher drive 564.

[0123] The support base 561 is located on the main frame 2 below the turntable and the workpiece positioning device 9. The support core 562 is movably disposed within the support base 561. The upper end of the support core 562 is used to contact the tooling base plate 91 of the workpiece positioning device 9, and the lower end of the support core 562 is provided with an arc-shaped guide surface to facilitate the insertion of the pusher 563.

[0124] The contact surface of the pusher 563 is inclined and contacts the lower end of the support core 562. The pusher drive 564 is preferably a cylinder, used to provide power for the movement of the pusher 563.

[0125] When the pressing device 5 needs to perform pressing, the push drive 564 pushes the push member 563 to translate. Under the action of the inclined plane, the support core 562 moves upward, thereby abutting against the tooling base plate 91, ensuring the stability of the workpiece positioning device 9, preventing the turntable from tilting, and ensuring the pressing effect of the motor. When pressing is finished, the push drive 564 drives the push member 563 to reset, and the support core 562 falls under gravity, leaving the tooling base plate 91, ensuring that the workpiece positioning device 9 can move smoothly to the next station.

[0126] Preferably, the support core 562 is movably disposed within the support base 561 by a support spring 565, which can prevent gravity failure and ensure that the support core 562 does not fall automatically.

[0127] [Screw fastening device]

[0128] The screw fastening device 6 is used to install screws between the end cover 1 and the barrel 12.

[0129] like Figure 14 As shown, the screw fastening device 6 includes a fastening frame 61, a fastening lifting frame 62, a fastening lifting drive component 63, and at least one screw fastening machine.

[0130] The fastening frame 61 is a frame structure with two vertical and parallel fastening guide rods 611 in its middle. A fastening lifting frame 62 is movably mounted on the fastening guide rods 611. A fastening lifting drive component 63 is fixed to the upper end of the fastening frame 61 and connected to the fastening lifting frame 62, providing power for the movement of the fastening lifting frame 62; it is preferably a cylinder. At least one screw-loading machine is mounted on the fastening lifting frame 62 for screw feeding and tightening; in this embodiment, three screw-loading machines are used.

[0131] Specifically, the screw machine includes a screw servo motor 64, an output link 65, and a screw working head 66. The screw working head 66 is existing technology and can be connected to the screw feeding and vibration reduction. When the screw enters the screw working head 66, the screw servo motor 64 tightens the screw through the output link 65.

[0132] The fastening lifting frame 62 includes an upper connecting plate 621 and an upper mounting plate 622 for mounting the screw servo motor 64, and a lower connecting plate 623 and a lower mounting plate 624 for mounting the output connecting rod 65.

[0133] At least one fastening link 627 is fixed between the upper mounting plate 622 and the lower mounting plate 624, so that the fastening lifting frame 62 forms a whole.

[0134] Since there are three screw-making machines, the upper mounting plate 622 and the lower mounting plate 624 have the same structure, having a front part, a rear part, a left part, and a right part, which together form a hollow structure. The rear part is movably mounted on the fastening guide rod 611, and the front part, rear part, and left part are all provided with at least one first elongated hole 625. In this embodiment, two first elongated holes 625 are provided side by side.

[0135] The upper connecting plate 621 and the lower connecting plate 623 are provided with at least one second elongated hole 626. In this embodiment, two second elongated holes 626 are provided side by side. The upper connecting plate 621 and the upper mounting plate 622, as well as the lower connecting plate 623 and the lower mounting plate 624, are fixed together by fasteners. The position of the upper connecting plate 621 / lower connecting plate 623 between the corresponding upper mounting plate 622 / lower mounting plate 624 can be adjusted according to the position of the screws, thereby satisfying the screw processing at different positions.

[0136] Preferably, a first rotor positioning clamping member 67 is provided at the bottom of the fastening frame 61, and the first rotor positioning clamping member 67 is preferably a clamping robot. During processing, the first rotor positioning clamping member 67 is used to clamp the upper end of the rotor 13, so that the motor 1 is fixed on the workpiece positioning device 9, which facilitates processing.

[0137]

[0138] The accessory mounting device 7 is used to assemble the pulley 15 or the motor nut. This embodiment is provided with two accessory mounting devices, including a first accessory mounting device for assembling the pulley 15 and a second accessory mounting device for assembling the motor nut. Their structures are basically the same. The first accessory mounting device for assembling the pulley 15 is described below as an example.

[0139] like Figure 15-17 As shown, the accessory installation device 7 includes an accessory mounting frame 71, an accessory translation mechanism 72, an accessory lifting mechanism 73, and an accessory clamping mechanism 74.

[0143] The accessory lifting frame 731 includes a plurality of accessory lifting rods 7311 movably mounted on the translation plate 721, an upper lifting plate 7312 fixed to the upper end of the accessory lifting rods 7311, and a lower lifting plate 7313 fixed to the lower end of the accessory lifting rods 7311. There are four accessory lifting rods 7311. The upper lifting plate 7312 has an opening to avoid the lifting drive component 732. The telescopic end of the lifting drive component 732 is connected to the lower lifting plate 7313. Driven by the lifting drive component 732, the accessory lifting frame 731 achieves stable lifting and lowering.

[0144] The accessory clamping mechanism 74 includes an installation platform 745, an accessory clamping drive 743 mounted on the installation platform 745, and an accessory rotation drive 744 that drives the accessory clamping drive 743 to rotate.

[0145] The mounting platform 745 is movably mounted on the lower lifting plate 7313 of the accessory lifting frame 731 via two sets of symmetrical guide pillars 741 and a return spring 742. Specifically, the upper end of the guide pillar 741 is fixedly connected to the lower lifting plate 7313, and the lower end of the guide pillar 741 is provided with a retaining edge. The mounting platform 745 has a guide pillar mounting hole on each of its left and right sides for the guide pillar 741 to pass through. A guide sleeve is fixed inside the guide pillar mounting hole. After passing through the guide sleeve and the return spring 742, the guide pillar 741 is fixedly connected to the lower lifting plate 7313. The retaining edge abuts against the mounting platform 745 or the guide sleeve. When accessories such as the pulley 15 are pressed onto the rotating shaft of the rotor 13, the return spring 742 can provide cushioning, ensuring that the accessories are not affected by excessive pressure or downward pressure distance, thus ensuring assembly quality.

[0146] The lower lifting plate 7313 is hollow in the middle to avoid the rotating drive component 744 of the accessory.

[0147] Preferably, the accessory mounting bracket 71 is provided with a lifting limit member 75 to limit the minimum height of the lower lifting plate 7313. The lifting limit member 75 is made of cushioning materials such as rubber and nylon.

The material distribution drive unit 793 drives the material distribution block 791 to move between the feeding position and the clamping position; when the material distribution block 791 is in the feeding position, the storage slot 792 is aligned with the end of the feeding channel 78; when the material distribution block 791 is in the clamping position, the material distribution block 791 blocks the end of the feeding channel 78 and positions the storage slot 792 below the accessory clamping mechanism 74.

[0152] Preferably, the bottom of the accessory mounting bracket 71 is further provided with a second rotor positioning clamp 76, which is preferably a clamping robot. During processing, the second rotor positioning clamp 76 is used to clamp the upper end of the rotor 13, so that the motor 1 is fixed on the workpiece positioning device 9, which facilitates processing.
