Description

Technical Field

[0001] The invention belongs to the technical field of component assembly, and in particular relates to an automatic rotor assembly device. Background Art

[0002] Rotor: A rotating body supported by bearings, which is the main rotating part in power machinery and working machinery;

[0003] The assembly steps of the rotor include: pre-preparation, installation of the transmission shaft, installation of the core, installation of the winding, fixing of parts and inspection, etc.

[0004] In the prior art, the assembly between the rotor and the transmission shaft is as follows: the rotor core after riveting is usually moved to a designated processing area by a manipulator, and then the transmission shaft is clamped by a clamping device directly opposite to the axis of the rotor core, and then the transmission shaft is driven to move toward the rotor core by a facing extrusion device until the transmission shaft is inserted into the axis of the rotor core, and finally, the assembly of the rotating parts is completed by the moving device;

[0005] However, when fully automatic batch rotor assembly is implemented, the vibration or external impact generated by the mechanical operation itself affects the positive overlap accuracy of the rotor core and the drive shaft axis, that is, it causes a deviation between the rotor core and the drive shaft axis, affecting the dynamic balance of the rotor under high-speed rotation, increasing the friction between the two, and shortening the service life. At the same time, high-frequency external impact or vibration increases the probability of radial movement of the drive shaft during the assembly process, which in turn leads to increased local friction and temperature, affecting rotor performance, changing energy transfer efficiency, increasing energy consumption, and reducing the assembly accuracy between the two.

[0006] In addition, dust and impurities in the assembly environment are continuously deposited or gathered on the mating surface between the two due to the accumulation of time or interference from other external factors such as human interaction. This will not only reduce the assembly accuracy between the rotor core and the drive shaft, affect the rotor speed and torque compliance rate, and reduce the accuracy of power transmission, but also further increase the wear between the two and increase operating costs.

[0048] S1: First, when the bottom plate reciprocates, the reciprocating gas rod is synchronously controlled to drive the receiving ring to move until the receiving ring coincides with the axis of the ring sleeve and the inner ring tube. After that, the packaging seat is controlled to move toward the receiving ring through the slide until the transmission shaft passes through the rotor core;

[0049] S2: Then, the top ring is rotated to a certain angle, and the guide rod is guided and limited by the ring plate, so that the guide rod drives the air gun rod to move synchronously until the ball contacts the ring sleeve or the outer wall of the transmission shaft, and the reset spring is in a compressed state at this time;

[0050] S3: Finally, the oil nozzle is driven to move toward the axis of the transmission shaft through the telescopic movable column. After that, the rubber sleeve is driven by the rotating oil ring to evenly apply lubricating oil to the outer wall of the transmission shaft in the horizontal motion state until a stable oil film is formed on the outer wall of the transmission shaft.

[0051] The present invention has the following beneficial effects:

[0052] 1. The present invention controls the inner ring tube to rotate to a specified angle through a top ring. During this process, the ring piece forces the guide rod to move synchronously through the guide groove thereon. Thereafter, the T-section cabin moves away from the axial end of the ring piece under the control of the air gun rod until the reset spring is compressed to a specified distance, and finally, when the ring sleeve near one end of the driven gear drives the transmission shaft to enter the inner ring tube, it rotates in the opposite direction by a specified angle until the ball contacts the outer wall of the ring sleeve, that is, the vibration kinetic energy is consumed and absorbed by the extension and compression of the reset spring when it is impacted, and is converted into heat energy and other forms; that is, the elastic characteristics of the spring have certain limitations and buffers on vibration or external impact, thereby effectively reducing the probability of radial movement of the transmission shaft during assembly and improving the assembly accuracy between the rotor core and the transmission shaft.

[0053] 2. The present invention controls the gap between the oil nozzle and the transmission shaft through a telescopic movable column, so as to improve its specific practicality and adaptability, that is, to ensure that the oil nozzle can drip oil to the transmission shafts with different shaft diameters, and at the same time reduce the probability of the oil nozzle being blocked by the dustproof plate, to a certain extent, to ensure the long-term operation effectiveness and smoothness of the oil nozzle, and in this process, the oil ring drives the rubber plug to rotate, thereby prompting the outer wall of the transmission shaft to form a uniform oil film, which can not only block dust and impurities from entering the mating surface, keep the interior clean, prevent lubricating oil leakage, and prevent water vapor or corrosive substances from directly contacting the mating surface, reducing the possibility of rust and corrosion, but also can reduce the friction coefficient, reduce the wear caused by mutual movement, alleviate vibration and noise levels, and extend the service life of the rotor core and the transmission shaft.

[0054] 3. The present invention provides real-time feedback to the operator on the contact status between the positive electrode plate and the negative electrode plate through a warning light, thereby prompting the operator to replace the corresponding end reset spring or recheck the overlap between the axis of the ring sleeve and the axis of the inner ring tube, fully ensuring that the reset spring alleviates and absorbs degradation at different angles, and the influence of external shock or vibration on the radial movement between the ring sleeve and the transmission shaft and the axis of the rotor core.

[0106] Next, when the ring piece 455 rotates, the guide rod 454 is forced to drive the end rod 453 and the air gun rod 456 to move away from the axis of the inner ring tube 45 to a specified position under the dual guiding and limiting effects of the guide groove and the guard plate 46 (when the ring piece 455 rotates, the arc groove 452 releases the local limit between the slide rod 49 and the inner ring tube 45 to ensure the smooth rotation of the inner ring tube 45 or the ring piece 455), and at this time the return spring 451 is compressed to a certain extent (the positive electrode 473 is not in contact with the negative electrode 474, and the warning light 48 is off), so as to ensure that the transmission shaft passes through the inner ring tube 45 smoothly, and avoid the collision and limitation of the air gun rod 456 or the rubber pad 472 with the transmission shaft in the moving state;

[0107] Finally, the ring piece 455 is reversed (when the transmission shaft passes through the T-section compartment 457 or the arc plug 471 points to the coverage area), and the driving gear 479 is controlled by the stepping motor 478 to make a different reversal than the above, until the arc plug 471 in one direction and the balls 458 in three directions simultaneously collide with the outer wall of the transmission shaft (maintaining a certain interaction force, and at this time the return spring 451 is in a compressed state);

[0108] When the transmission shaft in the current state is subjected to external impact or vibration again during movement and radial movement occurs:

[0109] The return spring 451 consumes and absorbs the vibration kinetic energy through its own extension and compression, and converts it into heat energy and other forms; that is, the elastic characteristics of the spring have certain limitations and buffers on vibration or external impact, thereby effectively reducing the probability of radial movement of the transmission shaft during assembly and improving the assembly accuracy between the rotor core and the transmission shaft;

[0110] In this process, the friction form between the ball 458 and the contact end face of the transmission shaft is changed to reduce the loss of the transmission shaft end face caused by friction (the rigid contact channel between the transmission shaft and the arc plug 471 is blocked by the rubber pad 472, that is, while the arc plug 471 provides a rigid support structure, the wear caused by the rigid friction between the two is further avoided), and the assembly accuracy between the transmission shaft and the rotor core is further improved. At the same time, cold gas of a certain temperature is continuously delivered to the air hole 459 through the T-section cabin 457 (specifically, cold gas can be delivered to the inside of the air gun rod 456 through an external pipeline, and finally evenly sprayed to the end face of the transmission shaft through the air hole 459). The low temperature can reduce the heat of the transmission shaft itself or the thermal deformation caused by the ambient temperature, ensure the assembly accuracy, achieve a tighter fit, and improve the assembly accuracy.

[0111] When a return spring 451 is damaged during long-term operation:

[0112] At this time, at the moment when the slide bar 49 loses the limit of the return spring 451 (this is a reaction to the extreme environment when the return spring 451 instantly loses its elasticity. Usually, the loss of spring elasticity is gradual. The extreme environment can better reflect the sensitivity and timeliness of the technical solution), it will inevitably drive the positive electrode sheet 473 to rush to the negative electrode sheet 474 and make a short contact with it. At this time, the warning light 48 lights up (the external recording program records the previous number of contacts), so as to provide feedback to the operator to replace the return spring 451;

[0113] In addition, a group of two springs can not only reduce the continuous guidance of the transmission shaft when a single spring loses its function, but also more accurately reflect the damage of one of the springs;

[0114] The formation process of the oil film on the outer wall of the transmission shaft:

[0115] When the transmission shaft continuously moves toward the receiving ring 13:

[0116] First, the oil nozzle 415 is driven to move toward the axis of the transmission shaft by the telescopic movable column 413 (refer to the principle of the telescopic cylinder 34 in the prior art);

[0117] Next, the external lubricating oil is guided to the oil nozzle 415 through the oil pipe 412 (soft material) (the dustproof plate 414 reduces the blockage of the oil passage of the oil nozzle 415 by dust or impurities in the external environment), and drips to the outer wall of the transmission shaft through the oil nozzle 415 (the speed of the lubricating oil dripping from the oil nozzle 415 is positively correlated with the moving speed of the transmission shaft, so as to ensure the same amount of lubricating oil falling to the outer wall of the transmission shaft per unit time);

[0118] Finally, the ring gear 4171, driven by the shaft gear 4172, causes the oil ring 417 to drive the rubber sleeve 418 in a rotating state, and to move substantially with the transmission shaft in the moving process, so as to achieve a full-scale coating effect on the outer wall of the transmission shaft. In specific implementation, the shaft gear 4172 can be driven to rotate by an external motor - the rubber sleeve 418 can be replaced and cleaned within a specified operating cycle, so as to ensure the cleanliness of the outer wall of the transmission shaft;

[0119] The oil groove 419 retains a portion of the lubricating oil in the rubber sleeve 418, which helps to improve the guidance of the lubricating oil during rotation and further enhance the lubricating effect of the lubricating oil.

[0120] Reference Figure 1 , Figure 3 and Figure 4 It can be seen that the control unit 3 includes: a side strip 31, which is detachably mounted on the end surface of the table 1 close to the side plate 41 by bolts, and the side plates 41 are arranged opposite to each other; a pad 32, which is clamped and mounted on the end of the side strip 31 away from the outer lining plate 22; a base 33, which is clamped and mounted on the middle position of the end surface of the pad 32 away from the side strip 31; a telescopic cylinder 34, which is clamped and mounted on the middle position of the end surface of the base 33 away from the pad 32;

[0121] The guide rail 35 is symmetrically mounted on the end surface of the side strip 31 close to the telescopic cylinder 34; the slide 36 is slidably mounted between the two guide rails 35; the packaging seat 37 is mounted on the end surface of the slide 36 away from the side strip 31; the plug rod 38 is rotatably mounted on the end of the packaging seat 37 away from the telescopic cylinder 34; the back plate 39 is mounted on the middle position of the outer wall of the plug rod 38 through the mounting ring;

[0122] Reference Figure 2 and Figure 3It can be known that a turning handle 391 is clamped and installed on the outer wall of one end of the insertion rod 38, and a torsion spring 392 is sleeved on the outer wall of the insertion rod 38 and is located between the turning handle 391 and the packaging seat 37. An electric telescopic rod 393 is clamped and installed on one end of the turning handle 391, and the electric telescopic rod 393 is symmetrically clamped and installed on the end away from the back plate 39 with a corner plate frame 394 clamped and installed with the slide 36. A top column 395 is clamped and installed on the end of the back plate 39 away from the telescopic cylinder 34, and a ring sleeve 396 is clamped and installed on the end of the top column 395 away from the back plate 39; the sum of the axial lengths of the ring sleeve 396 and the top column 395 is greater than the axial length of the outer ring tube 44, and the end face of the ring sleeve 396 close to the table plate 1 is tangent to the end face of the outer lining plate 22 away from the table plate 1 or the ring sleeve 396 is higher than the outer lining plate 22 by a specified distance.

[0123] Hereby explain:

[0124] 1. The space on one side of the side plate 41 is also provided with some components of the control unit 3, such as the slide 36, the packaging seat 37, the insertion rod 38, the back plate 39 and the rotating handle 391, so as to cooperate with the control unit 3 to squeeze the transmission shaft at both ends of the transmission shaft axis at the same time;

[0125] 2. The aforementioned correction unit 4 can be used to adjust the transmission shaft when it is subjected to vibration or external impact. Similarly, it can be used to guide the ring sleeve 396 when it moves. According to the ratio of the ring sleeve 396 to the shaft diameter of the transmission shaft, the inner diameter of the ring piece 455 and the corresponding elastic coefficient of the return spring 451 can be adaptively adjusted (so as to further improve the assembly accuracy of the rotor core and the transmission shaft);

[0126] Control process of the transmission shaft by control unit 3:

[0127] First, a transmission shaft is manually added to the inner part of the axis of the ring sleeve 396 on one side by a manipulator or an operator (the handle 391 is controlled by the electric telescopic rod 393 to drive the back plate 39 to reverse until the top column 395 drives the ring sleeve 396 to flip 90 degrees, so as to facilitate the placement of the transmission shaft or to clean the inner part of the axis of the ring sleeve 396 by an external cleaning device);

[0128] Next, the slide 36 controls the packaging seat 37 to move toward the inner ring tube 45 or the receiving ring 13 (in specific implementation, the position of the rotor core inside the receiving ring 13 can be fixed and limited by an external lifting device just above the receiving ring 13, which is not shown in the figure). Specifically, the slide 36 can be driven to move by the telescopic cylinder 34 (one side is shown, and the other side is not shown) until the ring sleeve 396 on one side conflicts with one side of the receiving ring 13, and the ring sleeve 396 on the other side passes through the inner ring tube 45, and drives the transmission shaft to pass through the rotor core until it conflicts with the inner wall of the other ring sleeve 396;

[0129] Finally, the elastic properties of the torsion spring 392 are used to further degrade and absorb the vibration of the ring sleeve 396 during the extrusion process, thereby fully ensuring the matching accuracy between the transmission shaft and the rotor core.

[0130] The working principle of the rotor automatic assembly equipment provided by the present invention is as follows: Step 1: First, when the bottom plate 11 reciprocates, the reciprocating gas rod 12 is synchronously controlled to drive the receiving ring 13 to move until the receiving ring 13 coincides with the axis of the ring sleeve 396 and the inner ring tube 45, and then the packaging seat 37 is controlled by the slide 36 to move toward the receiving ring 13 until the transmission shaft passes through the rotor core;

[0131] Step 2: Then, the top ring 475 is rotated to a certain angle, and the guide rod 454 is guided and limited by the ring plate 455, so that the guide rod 454 drives the air gun rod 456 to move synchronously, until the ball 458 contacts the ring sleeve 396 or the outer wall of the transmission shaft, and the return spring 451 is in a compressed state.

[0132] Step 3: Finally, the oil nozzle 415 is driven to move toward the axis of the transmission shaft by the telescopic movable column 413. Thereafter, the rubber sleeve 418 is driven by the rotating oil ring 417 to evenly apply lubricating oil to the outer wall of the transmission shaft in the horizontal motion state until a stable oil film is formed on the outer wall of the transmission shaft.
