[0049] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0050] Embodiment 1:

[0051] Combination Figures 1 to 9 As shown, an embodiment of the present invention provides a motor rotor assembly device, including a turntable assembly 100 for conveying a stator, and a size detection mechanism 200 and a press-fit mechanism 300 are sequentially arranged along the turntable assembly 100; the size detection mechanism 200 is used to detect the size of the stator. The press-fit mechanism 300 includes two groups of press-fit assemblies 310 opposite to each other in the vertical direction, and a centering assembly 320 and a clamping assembly 330 are arranged at the driving end of the press-fit assembly 310. The clamping assembly 330 is used to clamp the rotor, and the clamping assembly 330 is arranged concentrically with the centering assembly 320.

[0052] The centering component 320 includes a shell 321, which is provided with a rotating cavity, which is rotatably connected to the first disc body 322, and the first disc body 322 is provided with a plurality of transmission grooves 323 along its circumferential direction, and the transmission grooves 323 are gradually inclined inward along a preset rotation direction; a transmission component 324 is slidably connected in the transmission groove 323, and the transmission component 324 is arranged in a radial direction, and a centering end 325 is provided at one end of the transmission component 324 facing the center of the first disc body 322, and the centering end 325 is used to abut against the outer wall of the rotor.

[0053] The working principle of the present invention is as follows: when working, the stator is placed on the turntable assembly 100, and the turntable assembly 100 drives the stator to rotate along the preset rotation direction and move to the position of the size detection mechanism 200 to detect the size of the stator. At the same time, the two sets of press-fit mechanisms 300 clamp the upper rotor and the lower rotor respectively through the clamping assembly 330 to play a preliminary centering role; then the stator is driven to rotate to the position of the press-fit mechanism 300, and the centering assembly 320 is operated to drive the first disc body 322 to rotate along the preset rotation direction in the rotating cavity. During the rotation process, due to the setting method of the transmission groove 323, the transmission assembly 324 will be pushed to move inward in the radial direction. The plurality of transmission components 324 move synchronously, pushing the centering end 325 to contact the outer wall of the rotor in different directions, so as to realize the precise centering of the rotor. The pressing component 310 operates to drive the two sets of centering components 320 to move closer to each other, and make the upper rotor and the lower rotor accurately aligned in the stator and complete the pressing assembly. This equipment is mainly for the assembly of split rotors. By synchronously installing the upper rotor and the lower rotor, it is ensured that the rotor always maintains high concentricity during the assembly process. By introducing the size detection mechanism 200 and multiple sets of pressing mechanisms 300, multiple precise centering of the rotor is realized, thereby improving the assembly quality and the overall performance of the motor.

[0054] In the present embodiment, it is specifically described that the size detection mechanism 200 includes a thickness detection component 210 and a diameter detection component 220; the thickness detection component 210 includes a first fixed plate 211 and a second fixed plate 212, the first fixed plate 211 is provided with a first cylinder 213, and the piston rod of the first cylinder 213 is connected to a crimping plate 214; the lower end surface of the second fixed plate 212 is provided with a second cylinder 215, and the upper end surface of the second fixed plate 212 is provided with a fixed seat 216, and the fixed seat 216 is slidably connected with a measuring seat 217 through a guide column, and a measuring spring 218 is sleeved on the guide column, and a force sensing element is provided at one end of the measuring spring 218; during detection, the first cylinder 213 drives the crimping plate 214 to move to a first preset height to limit the upper end surface of the stator; at the same time, the first cylinder 213 drives the second fixed plate 212 to move upward to a second preset height, and the measuring seat 217 abuts against the lower end surface of the stator, and the thickness of the stator is measured by the detection data of the force sensing element.

[0055] It should be noted that during the detection process, the first cylinder 213 drives the crimping plate 214 to move to the first preset height to limit the upper end surface of the stator; at the same time, the first cylinder 213 drives the second fixing plate 212 to move upward to the second preset height, so that the measuring seat 217 contacts the lower end surface of the stator. The detection data obtained by the force sensing element can accurately measure the thickness of the stator. This design realizes the accurate measurement of the stator thickness through the coordinated action of the dual cylinders, improves the efficiency of dimensional detection, and at the same time, the setting of the measuring spring 218 can play the role of elastic buffer to avoid pressure loss on the stator.

[0056] In this embodiment, it is further explained that the diameter detection component 220 includes a rotating driving member 221 arranged on the first fixed plate 211, and a connecting rod 222 is provided at the driving end of the rotating driving member 221, and a measuring cylinder 223 is sleeved on the connecting rod 222; a notch portion is opened on the side wall of the measuring cylinder 223, and a measuring piece 224 is provided in the notch portion, and an elastic member is provided between the measuring piece 224 and the measuring cylinder 223; wherein, the lower end portion of the measuring piece 224 is a conical section.

[0057] It should be noted that, in the actual measurement process, the rotating driving member 221 drives the connecting rod 222 and the measuring cylinder 223 to rotate, and the measuring piece 224 contacts the outer diameter of the stator, and the elastic member plays the role of elastic buffering and protection. At the same time, the inner diameter of the stator can be determined by the elastic force transmitted by the elastic member. The conical cross-section design enables the measuring piece 224 to flexibly adapt to stators of different diameters while ensuring the accuracy of the measurement. The diameter detection component 220 realizes efficient detection of the stator diameter through structural optimization.

[0058] In this embodiment, it is specifically described that the number of the first cylinders 213 is set to two groups, and the two groups of first cylinders 213 are respectively arranged on both sides of the rotating drive member 221. A limiting rod 225 is laterally arranged at one end of the connecting rod 222, and the length of the limiting rod 225 is greater than the spacing between the two groups of first cylinders 213, so that the limiting rod 225 is limited by the two groups of first cylinders 213 during rotation.

[0059] When the rotary drive member 221 is in operation, the limit rod 225 can be stably subjected to the force of the two groups of cylinders, thereby limiting the rotation angle of the measuring cylinder 223, improving the stability of the measuring cylinder 223 during the measurement process, and avoiding disordered rotation.

[0060] In this embodiment, it is specifically described that the clamping assembly 330 includes a fixed disk 331, and a second circular rotating disk 332 rotatably connected to the fixed disk 331, the second circular rotating disk 332 is provided with a plurality of curved grooves 333 along its circumferential direction, each curved groove 333 is gradually inclined inward along a preset rotation direction; the curved groove 333 is slidably connected with a connecting block 334, the fixed disk 331 is provided with a plurality of adjustment grooves 335 along its radial direction, each adjustment groove 335 is respectively slidably provided with a clamping claw body 336, and one end of the clamping claw body 336 is connected to the connecting block 334; the second circular rotating disk 332 rotates to drive a plurality of clamping claw bodies 336 to open or clamp relatively.

[0061] When the second rotating disk 332 rotates, the connecting block 334 in the curved groove 333 moves accordingly, driving the clamping claws 336 to relatively open or clamp. This design enables the clamping assembly 330 to flexibly and accurately control the movement of the clamping claws 336, achieve reliable clamping of the rotor, and improve the operational stability and efficiency during the assembly process. At the same time, due to the design of multiple circumferential clamping claws 336, it can play a preliminary centering role for the rotor.

[0062] In this embodiment, it is further explained that a side connection portion 3221 is provided on one side of the first disc body 322, and the side connection portion 3221 is rotatably connected to a rotating shaft body 3222; a connecting plate 326 is provided on one side of the shell 321, and a first driving member 327 is rotatably connected to the connecting plate 326, and a driving end of the first driving member 327 is connected to the rotating shaft body 3222, and the first driving member 327 is used to drive the side connection portion 3221 to swing, so as to drive the first disc body 322 to rotate.

[0063] It should be noted that the first disc body 322 of the present solution drives the side connection part 3221 to swing by the first driving member 327, thereby driving it to rotate, which can ensure the synchronization of the movement of multiple transmission components 324. At the same time, this side-mounted method can reasonably arrange the installation space of the equipment.

[0064] In this embodiment, it is specifically described that a detection portion 3223 is provided at the upper end of the rotating shaft body 3222, and a first detector 328 and a second detector 329 are also provided at intervals on the connecting plate 326. When the detection portion 3223 rotates to the bottom of the first detector 328 or the second detector 329, an induction signal is generated accordingly.

[0065] During operation, when the rotating shaft body 3222 rotates to the bottom of the first detector 328 or the second detector 329, an induction signal will be generated. At this time, the control system will control the first driving member 327 to stop moving, thereby limiting the swing stroke of the side connecting part 3221, and then controlling the moving stroke of the transmission assembly 324, thereby protecting the rotor and avoiding collision.

[0066] In this embodiment, it is specifically described that the turntable assembly 100 includes a turntable body 110, and a plurality of receiving grooves 111 for accommodating the stator are arranged along the circumferential direction of the turntable body 110. A rotating motor 120 is arranged below the turntable body 110, and a divider is arranged at the driving end of the rotating motor 120, and the divider is connected to the turntable body 110.

[0067] It should be noted that the turntable assembly 100 of the present solution drives the indexer through the rotating motor 120, thereby driving the rotation of the turntable body 110, so as to achieve a controllable and recordable angle during the rotation of the turntable body 110, thereby improving the rotation displacement accuracy of the stator.

[0068] In this embodiment, it is further explained that the motor rotor assembly equipment also includes a verification component 400, which is arranged before the size detection mechanism 200. The verification component 400 includes a lifting cylinder 410, and the driving end of the lifting cylinder 410 is connected to a cleaning cylinder 420. The cleaning cylinder 420 is provided with a plurality of cleaning sheets 421 along its circumferential direction, wherein a buffer spring is provided between the cleaning sheet 421 and the cleaning cylinder 420.

[0069] After the stator is loaded, the inner diameter of the stator needs to be cleaned by the calibration component 400 to prevent the influence of residues or contaminants on the rotor assembly. At the same time, the buffer spring plays the role of elastic buffer and protects the inside of the stator.
