TECHNICAL FIELD

[0001] The application belongs to the technical field of motor assembly equipment, and particularly relates to a motor positioning device and motor press-fitting equipment. BACKGROUND

[0002] A motor is generally assembled by a fan blade, a motor cylinder, a rotor and an end cover.

[0003] At present, in traditional motor assembly, press-fitting of the motor cylinder and the rotor, press-fitting of the rotor and the fan blade, and press-fitting of the end cover and the motor cylinder and the rotor are completed in steps, and a corresponding motor component positioning tool is required for each process, resulting in relatively high cost.

[0004] Generally, a threaded hole is arranged on the motor cylinder, and a corresponding through hole is arranged on the end cover. During installation of the end cover and the motor cylinder, the position of the end cover needs to be circumferentially determined so that the through hole corresponds to the threaded hole, and the screw is fixed in the threaded hole, thereby realizing fixed connection of the end cover and the motor cylinder.

[0005] The traditional motor component positioning tool does not have a corresponding structure to ensure the circumferential position of the two, and generally only relies on the professional operation level of the operator. This requires relatively high operation of the operator, and a careless mistake may occur, resulting in unqualified motor assembly and affecting the qualified rate of assembly. SUMMARY

[0006] The application aims to provide a motor positioning device and motor press-fitting equipment which are simple in structure and convenient to position.

[0012] The end cover positioning mechanism comprises:

[0013] an end cover positioning frame installed on the tooling table;

[0014] a lifting positioning seat which is lifted and arranged on the end cover positioning frame;

[0015] a first elastic return member installed between the end cover positioning frame and the lifting positioning seat and used for providing an upward force of the lifting positioning seat; and

[0016] An end cap positioning assembly is mounted on the lifting positioning seat;

[0017] The end cap positioning assembly includes:

[0018] The positioning connector is rotatably mounted on the lifting positioning seat at one end via a rotating shaft;

[0019] End cap positioning pin, disposed at the other end of the positioning connector; and

[0020] The second elastic reset member is disposed between the lifting positioning seat and the positioning connector, and is used to provide the positioning connector with a force to move away from the guide position.

[0021] Preferably, the lower end of the end cap positioning pin is provided with a tapered guide portion for insertion into the fixing hole of the end cap.

[0022] Preferably, it further includes an end cap guide mechanism, which includes an end cap guide rod.

[0023] The positioning connector has an end cap guide hole that matches the upper end of the end cap guide rod.

[0024] When the end cap guide rod is inserted into the end cap guide hole, the end cap positioning assembly can move along the axial direction of the end cap guide rod.

[0025] Preferably, the end cap guiding mechanism further includes a guide block and a third elastic reset member. The guide block has an installation channel, and the end cap guide rod is movably mounted on the installation channel through the third elastic reset member.

[0026] Preferably, the end cap guide mechanism further includes an adjustment seat, and the guide block is adjustablely disposed on the adjustment seat by an adjustment member.

[0027] Preferably, the barrel positioning mechanism includes a barrel positioning seat fixed on the tooling table. The barrel positioning seat has an annular barrel mounting position, and the barrel mounting position is provided with a plurality of screw positioning grooves for positioning motor screws.

[0028] Preferably, the width of the screw positioning groove is greater than the diameter of the motor screw, the inner edge of the screw positioning groove is used to position a small-sized motor, and the outer edge of the screw positioning groove is used to position a large-sized motor.

[0029] Preferably, the barrel positioning mechanism further includes a fan blade positioning seat disposed at the center of the barrel positioning seat and a plurality of fan blade positioning pins disposed on the fan blade positioning seat.

[0030] An electric motor pressing device includes a motor positioning device and a pressing device;

[0031] The pressing device includes:

[0032] Press frame,

[0033] The press-fitting drive component is located at the upper end of the press-fitting machine frame and is used to generate press-fitting power;

[0034] A pressing frame is movably mounted on the pressing machine frame and connected to the pressing drive component;

[0035] A rotor pressing mechanism is disposed in the middle of the pressing frame; and

[0036] An end cap pressing mechanism is mounted on a pressing frame and includes an end cap pressing plate located on the outer periphery of the rotor pressing mechanism.

[0037] Preferably, the rotor pressing mechanism includes:

[0041] The outstanding and beneficial technical effects of this invention compared to the prior art are:

[0042] 1. The barrel positioning mechanism of the present invention is used to position the barrel, and the end cap positioning mechanism is used to position the end cap. Before the motor is pressed, the end cap positioning pin of the end cap positioning mechanism extends into the fixing hole of the end cap to position the end cap. After the pressing is completed, the first elastic reset member can automatically drive the end cap positioning mechanism to move upward and make the end cap positioning pin leave the fixing hole.

[0043] 2. Since the end cap positioning mechanism of the present invention is provided with a second elastic reset member, after the end cap positioning pin leaves the fixing hole after the pressing is completed, the end cap positioning component rotates and resets under the action of the second elastic reset member, thereby leaving the top of the fixing hole, so that the motor screw can be inserted into the fixing hole of the end cap in the next process.

Detailed Implementation

[0063] The present invention will be further described below with reference to specific embodiments:

[0064] An electric motor pressing device includes a pressing device and a motor positioning device for pressing the fan blade 11, the barrel 12, the rotor 13 and the end cover 14 of the motor 1.

[0065] The motor positioning device in this embodiment is used to position the fan blade 11, the barrel 12 and the end cover 14 of the motor 1, so that after the pressing device completes the pressing, the motor screw 16 can be fixed by the screw fixing device.

[0066] like Figure 1 As shown, the motor 1 in this embodiment includes a fan blade 11, a barrel 12, a rotor 13, an end cover 14, and a motor screw 16. Motor bearings are respectively provided at the front and rear ends of the rotor 13. A front end cover and a rear end cover need to be press-fitted to both the front and rear ends of the barrel 12 and fixed by the motor screw 16. In this embodiment, the rear end cover is mainly used for positioning the barrel 12 and the rear end cover. The rear end cover has already been press-fitted by other equipment before processing and fixed by the motor screw 16.

[0067] Therefore, during the press-fitting process in this embodiment, the rear end of the rotor 13 needs to pass through the rear end cover of the barrel 12 and the fan blade 11, and the motor bearing at the rear end is installed on the rear end cover of the barrel 12. The front end of the rotor 13 needs to be fitted with the end cover 14 processed in this embodiment, and the motor bearing at the front end is installed on the end cover 14.

[0068] The fan blade 11 includes a circular fan blade body 111, blades 113 arranged circumferentially on the fan blade body 111, a shaft mounting part 112 arranged 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 arranged between the shaft mounting part 112 and two symmetrical blades 113. The fan blade body 111 has two fan blade positioning holes 115.

[0069] At least one reinforcing ridge 121 extends from the front side wall of the barrel 12. The reinforcing ridge 121 has threaded holes at both ends. In this embodiment, three reinforcing ridges 121 are provided, and each reinforcing ridge 121 has a threaded hole for threaded connection of the motor screw 16.

[0070] The end cap 14 is provided with mounting protrusions around the reinforcing protrusions 121. The mounting protrusions are provided with fixing holes 141 corresponding to the threaded holes. The fixing holes 141 are through holes. After the end cap 14 is pressed into the barrel 12, the motor screw 16 passes through the fixing holes 141 and is fixedly connected to the threaded holes to achieve fixed installation of the two.

[0071] like Figures 2-4 As shown, the motor positioning device includes a tooling table 21, a barrel positioning mechanism 22, an end cap positioning mechanism 23, and an end cap guiding mechanism 24.

[0072] Tooling table 21 is generally set on the turntable of the workstation switching device to facilitate its transportation to the corresponding processing workstation. The processing workstations generally include the loading workstation, the pressing workstation, and the screw fixing workstation.

[0073] The barrel positioning mechanism 22 is used to position the barrel 12. It includes a barrel positioning seat 221 fixed on the tooling table 21, a fan blade positioning seat 222 located at the center of the barrel positioning seat 221, and a plurality of fan blade positioning pins 223 disposed on the fan blade positioning seat 222. 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 positioned after being inserted into the fan blade positioning pins 925.

[0074] In this embodiment, the barrel positioning seat 221 positions the barrel 12 using the motor screws 16 on the rear end cover. Specifically, the barrel positioning seat 221 is annular, with multiple perforated holes on its sidewalls. Fasteners pass through the first fixing holes below the perforated holes and are fixedly connected to the tooling table 21. The upper end of the barrel positioning seat 221 forms a barrel mounting position, which has several screw positioning grooves 2211 and parallel screw guide grooves 2212 for positioning the motor screws 16.

[0075] The screw guide groove 2212 has an arc-shaped guide slope to guide the motor screw 16. Then, by rotating the barrel 12, the motor screw 16 enters the screw positioning groove 2211 and abuts against one end wall of the screw positioning groove 2211, thus achieving the positioning of the barrel 12. If the operator is skilled, the screw can also enter the screw positioning groove 2211 directly without going through the screw guide groove 2212.

[0076] If the robotic arm is used to load the barrel 12, then the screw guide groove 2212 is not needed.

[0077] Preferably, to increase applicability, the width of the screw positioning groove 2211 is greater than the diameter of the motor screw 16. The inner edge of the screw positioning groove 2211 is used to position small-sized motors, and the outer edge of the screw positioning groove 2211 is used to position large-sized motors. For smaller-sized motors, the inner edge of the screw positioning groove 2211 is adapted to the innermost sidewall of the motor screw 16, which is the sidewall portion of the outermost sidewall of the motor screw 16 closest to the end cover axis. For larger-sized motors, the outer edge of the screw positioning groove 2211 is adapted to the outermost sidewall of the motor screw 16, which is the sidewall portion of the outermost sidewall of the motor screw 16 furthest from the end cover axis.

[0078] The bottom of the fan blade positioning seat 222 extends outward with an outer fixing edge, and the fastener passes through the second fixing hole on the outer fixing edge and is fixedly connected to the tooling table 21.

[0079] like Figure 4 As shown, the fan blade positioning seat 222 has a clearance groove 2221 for avoiding the shaft mounting part 112 and the reinforcing rib 114. The clearance groove 2221 can be a groove or a hole. Since the assembled fan blade 11 has a shaft mounting part 112, a blade 113, and a reinforcing rib 114 protruding to the same side, this embodiment has a clearance groove 2221. When the fan blade 11 is placed into the fan blade positioning seat 222, the shaft mounting part 112 and the reinforcing rib 114 enter the clearance groove 2221, and the blade 113 is located in the space between the fan blade positioning seat 222 and the barrel positioning seat 221. This ensures that the fan blade body 111 of the fan blade 11 can fully contact the upper surface of the fan blade positioning seat 222. When the rotor 13 and the fan blade 11 are pressed together, the force-bearing area of ​​the fan blade 11 is increased, effectively preventing its deformation.

[0080] In addition, the barrel positioning seat 221 supports the outer edge of the rear end cover of the barrel 12, and the fan blade positioning pin 925 can support the center of the rear end cover. During rotor pressing, deformation of the rear end cover of the barrel 12 can be effectively prevented.

[0081] like Figures 2-5 As shown, the end cap positioning mechanism 23 is used to position the end cap 14 to ensure that after the end cap 14 is press-fitted, its fixing hole 141 corresponds to the threaded hole of the barrel 12.

[0082] The end cap positioning mechanism 23 includes an end cap positioning frame 231, a lifting positioning seat 232, a first elastic reset member 233, and an end cap positioning assembly 234.

[0083] An end cap positioning frame 231 is mounted on the tooling table 21 and has two lifting guide rods. A lifting positioning seat 232 is movably mounted on the middle of the two lifting guide rods via a lifting guide sleeve, and an end cap positioning assembly 234 is mounted on the lifting positioning seat 232. A corresponding first elastic reset member 233 is sleeved on the bottom of the two lifting guide rods. The first elastic reset member 233 is mounted between the end cap positioning frame 231 and the lifting positioning seat 232 to provide the lifting force for the lifting positioning seat 232 to rise. The first elastic reset member 233 is preferably a spring.

[0084] The lifting positioning seat 232 is provided with a rotating bearing 235, and a rotating shaft 236 is provided inside the rotating bearing 235. The end cover positioning assembly 234 is rotatably mounted on the lifting positioning seat 232 via the rotating shaft 236.

[0085] The end cap positioning assembly 234 includes a positioning connector 2341, an end cap positioning pin 2342, a second elastic reset member 2343, and a guide core 2345.

[0086] One end of the positioning connector 2341 is rotatably mounted on the lifting positioning seat 232 via a rotating shaft 236. The other end of the positioning connector 2341 is provided with an end cap positioning pin 2342. The lower end of the end cap positioning pin 2342 is provided with a tapered guide portion for insertion into the fixing hole 141 of the end cap 14, which facilitates the positioning of the end cap during press fitting.

[0087] For better positioning, a guide core 2345 is provided inside the tapered guide portion. The guide core 2345 extends out of the tapered guide portion to fit into the threaded hole on the barrel 12. When the tapered guide portion is inserted into the fixing hole 141 of the end cap 14, the guide core 2345 can extend into the threaded hole, achieving better guidance and positioning during press fitting.

[0088] Preferably, the guide core 2345 can be integrally set or separately set at the lower end of the end cap positioning pin 2342. In this embodiment, it is separately set.

[0089] It should be noted that the fixing hole 141 of the end cap 14 is both the guide hole for end cap positioning and the mounting hole for the motor screw 16. Therefore, after press-fitting, the end cap positioning pin 2342 needs to automatically disengage from the fixing hole 141 to facilitate the installation of the motor screw 16 in the next process. To solve the above problem, a second elastic reset member 2343 is provided between the lifting positioning seat 232 and the positioning connector 2341. This can be a tension spring or a torsion spring, used to provide the force for the positioning connector 2341 to leave the guide position.

[0090] The guide position is the position where the end cap 14 is placed on the machine barrel before pressing and needs to be positioned by the end cap positioning pin 2342.

[0091] like Figure 5 As shown, when the second elastic reset member 2343 is a tension spring, the tension spring is fixed between the positioning connector 2341 and the lifting positioning seat 232 by screws. In its natural state, it drives the end cap positioning assembly 234 to approach the end cap positioning frame 231.

[0092] When the second elastic reset member 2343 is a torsion spring, it is mounted on the rotating shaft 236 and drives the end cap positioning assembly 234 to approach the end cap positioning frame 231.

[0093] like Figures 3-4 As shown, the end cap guide mechanism 24 is used to guide the end cap positioning assembly 234 to rise and fall, and includes an adjustment seat 244, an end cap guide rod 241, a guide block 242 and a third elastic reset member 243.

[0094] The adjusting seat 244 is disposed on the tooling table 21 between the end cap positioning frame 231 and the barrel positioning seat 221. The guide block 242 is adjustablely disposed on the adjusting seat 244 via an adjusting member. The initial height of the guide block 242 can be easily adjusted according to the height of the barrel, which helps to increase the applicability of the product.

[0095] The guide block 242 has a vertically formed installation channel, with guide sleeves at both ends. An end cap guide rod 241 is movably positioned between the two guide sleeves, meaning the lower end of the end cap guide rod 241 is located within the installation channel of the guide block 242. A long guide hole is formed on one side wall of the guide block 242, and a guide pin 245 is installed within the long guide hole to fix the end cap guide rod 241, making the lifting and lowering of the end cap guide rod 241 more stable.

[0096] A limiting block 246 is provided in the middle of the end cap guide rod 241. A third elastic reset member 243 is provided between the limiting block 246 and the guide block 242. The third elastic reset member 243 is preferably a spring, which provides the force for the end cap guide rod 241 to move upward. The limiting block 246 has a guide notch and is located outside the reinforcing rib 121 of the barrel. The limiting block 246 can limit the position of the end cap guide rod 241 while fixing the third elastic reset member 243.

[0097] The upper end of the end cap guide rod 241 is provided with a guide end, and the positioning connector 2341 is provided with an end cap guide hole 2344 that is adapted to the guide end of the end cap guide rod 241. When the end cap guide rod 241 is inserted into the end cap guide hole 2344, the end cap positioning assembly 234 can move along the axial direction of the end cap guide rod 241.

[0098] Installation steps:

[0099] First, the fan blade 11 and the casing 12 with the rear end cover are manually installed into the casing positioning mechanism 22. Then, the end cover 14 is placed on the casing 12, and the end cover positioning assembly 234 is manually driven so that the end cover positioning pin 2342 is inserted into the fixing hole 141 of the end cover 14, and the end cover guide hole 2344 of the positioning connector 2341 is inserted into the guide end of the end cover guide rod 241, completing the positioning of the press-fitted front end cover. At this time, the first elastic reset member 233 has not yet contacted the lifting positioning seat 232.

[0100] During press-fitting, the press-fitting device will press down on the end cap and the end cap positioning assembly 234 together, thereby driving the lifting positioning seat 232 to squeeze the first elastic reset member 233, and at the same time causing the end cap guide rod 241 to move down.

[0101] After pressing is completed, the pressing device leaves, and the first elastic reset member 233 drives the lifting positioning seat 232 and the end cover positioning assembly 234 to move upward, so that the end cover guide hole 2344 of the positioning connector 2341 leaves the end cover guide rod 241, and the end cover positioning pin 2342 leaves the fixing hole 141 of the end cover 14. Under the action of the second elastic reset member 2343, the end cover positioning assembly 234 rotates and resets, thereby leaving the top of the fixing hole 141, realizing the function of automatic resetting of the end cover positioning assembly 234, which facilitates the insertion of the motor screw 16 into the fixing hole 141 of the end cover 14 in the next process.

[0102] like Figures 6-7 As shown, the pressing device 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.

[0103] The press frame 51 includes a base 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.

[0104] 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.

[0105] 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. 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.

[0106] In order to improve the quality of pressing, the pressing device in this embodiment uses a pressing drive 52 to press the rotor 13 and the end cover 14 in stages. First, the rotor 13 is pressed with the barrel 12 and the fan blade 11, and then the end cover 14 is pressed with the rotor 13 and the barrel 12.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] 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.

[0111] like Figure 8 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.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] 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.

[0120] like Figure 9 As shown, the motor pressing equipment also includes a support unit 56 located below the motor positioning device, which has a support base 561, a support core 562, a pushing component 563, and a pushing drive component 564.

[0121] The support base 561 is located below the turntable and the motor positioning device. 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 table 21 of the motor positioning device, 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.

[0122] 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.

[0123] When the pressing device 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 table 21, ensuring the stability of the motor positioning device, preventing the turntable from tilting, and ensuring the motor pressing effect. When pressing is completed, the push drive 564 drives the push member 563 to reset, and the support core 562 falls under gravity, leaving the tooling table 21, ensuring that the motor positioning device can move smoothly to the next station.

[0124] 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.

[0125] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
