Description

Technical Field

[0001] The utility model relates to the technical field of motor rotor production equipment, in particular to an automatic feeding device for motor bearings. Background Art

[0002] A motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. Its main function is to generate driving torque. As a power source for electrical appliances or various machines, the motor is mainly composed of two parts: a stator and a rotor. The rotation of the rotor is achieved through the electromagnetic induction transmission between the stator and the rotor. Among them, the overall structure of the motor rotor is composed of a rotating shaft, an iron core and an armature winding. The iron core of the motor rotor is often formed by stacking several rotor laminations in sequence during the assembly process. The stacked rotor laminations are fixed at both ends of the rotor laminations by two riveted fixing blocks to form an iron core. The rotating shaft is vertically installed inside the iron core. Among them, due to the rotating shaft, the rotor is fixed at both ends of the rotor lamination by two riveted fixing blocks. The sub-laminates are in the shape of discs with a shaft hole at the center. Several rotor laminations are aligned with the same center and stacked. After stacking, they are riveted and fixed to form an iron core. During the assembly process, the shaft must first be inserted into the shaft hole of the rotor laminations, and retaining springs are clamped at both ends of the shaft. The shaft is fixed by the retaining springs to prevent radial movement of the shaft. In order to facilitate the rotation of the rotor shaft inside the stator, bearings must be installed on the outside of both ends of the shaft. Bearings are an important component in modern mechanical equipment. The main function of bearings is to support the mechanical rotating body, reduce its friction coefficient during movement, and ensure its rotation accuracy.

[0003] The existing rotor shaft is mostly installed manually during the bearing installation process. The bearing is placed and aligned with the shaft before the bearing is pressed. The manual bearing material removal method is inefficient, and the bearing is prone to tilt when aligning the bearing to the shaft, and the concentricity of the bearing and the shaft cannot be ensured. Before the existing pressing equipment presses the bearing to the shaft, it needs to be manually placed on the pressing station. If the placement position is offset, it will cause bearing damage or shaft bending, which will affect the efficiency of automated production.

[0004] With reference to the Chinese utility model patent with the patent publication number of "CN209507002U" and the patent name of "Bearing Pushing Device and Motor Assembly Equipment", the technical solution discloses "a bearing pushing device and motor assembly equipment, the bearing pushing device comprising: a base, a pushing assembly, a driver and a feeding assembly, the base being mounted on an external device, the pushing assembly, the driver and the feeding assembly being mounted on the base, the driver being used to drive the pushing assembly to perform linear motion, the feeding assembly being located on the side of the pushing assembly away from the driver, the feeding assembly being used to realize the sequential falling of the bearings from the accommodating tube, and the pushing assembly being used to push the bearings out sequentially". Although this technical solution can realize the automatic pushing out of the bearings for feeding, it is easy to push out multiple bearings during the pushing out of the bearing feeding process. When pushing multiple bearings, jamming will occur and it cannot be guaranteed that the bearings are pushed out one by one to the pressing position, and it cannot be guaranteed that the bearings and the rotor shaft are limited when pressing the bearings and the rotor shaft, which easily causes positional offset when pressing the bearings and the rotor shaft.

[0005] Therefore, how to realize the automatic bearing loading action is a technical problem that the technicians need to solve. Utility Model Content

The side of the circular arc opening 422 facing the rotating shaft is in contact with the outer wall of the rotating shaft.

[0038] Specifically, when the two clamping plates 42 of the clamping mechanisms 4 are fitted together, the two arc-shaped grooves 421 merge with each other to form a clamping circular hole for the bearing to be placed in, and the two arc openings 422 merge with each other to form a pressing circular hole for the rotating shaft to be placed in, and the central axis of the pressing circular hole and the central axis of the clamping circular hole are both located on the same central axis.

[0039] Specifically, a rotating motor 13 is provided directly below the rotating circular plate 1 , a power output end of the rotating motor 13 is fixed to the bottom of the rotating circular plate 1 , and the rotating motor 13 is used to control the rotation direction of the rotating circular plate 1 .

[0040] Specifically, the motor fixing seat 31 and the bearing base 32 are both arranged on the same straight line, and circular through holes are opened at the centers of the motor fixing seat 31 and the bearing base 32, and the circular through holes are used for inserting the rotating shaft.

[0041] Specifically, when one end of the sliding plate 3 is located directly below the rotating circular plate 1 , the outer portion of the bearing base 32 abuts against the blanking stopper 12 .

[0042] Specifically, a limiting tube body 321 is provided on the top of the bearing base 32, the outer diameter of the limiting tube body 321 is adapted to the inner diameter of the bearing, and the height of the limiting tube body 321 is consistent with the height of the bearing, and the blanking baffle 12 is provided with an arc-shaped bayonet on the side facing the limiting tube body 321.

[0043] Specifically, a plurality of material taking openings 14 are evenly distributed on the outside of the rotating circular plate 1 , and the plurality of material taking openings 14 correspond one-to-one to the plurality of material blanking through holes 11 , and the plurality of material taking openings 14 are used for the bearing base 32 to enter.

[0044] Example 1

[0045] In order to realize the automatic material removal action of the bearing and feed the material to the alignment pressing mechanism, in this embodiment: a plurality of feeding rods 10 are evenly distributed on the top of the rotating circular plate 1, and a plurality of blanking holes 11 are evenly distributed on the surface of the rotating circular plate 1, and the ends of the plurality of feeding rods 10 are matched one by one with the plurality of blanking holes 11, and blanking baffles 12 are movably provided at the bottoms of the plurality of blanking holes 11, so that one side of the blanking baffles 12 faces the rotating circular plate 1, and the bearings in the blanking holes 11 can be blocked by the blanking baffles 12, and a plurality of bearings are stacked in sequence by the feeding rods 10, and the bearings can slide into the blanking holes 11 through the feeding rods 10;

[0046] When the pushing mechanism 20 drives the sliding plate 3 to slowly retract, the blanking baffle 12 pops out again to block the bottom of the blanking hole 11, preventing the next bearing from falling through the blanking hole 11.

[0047] It should be noted that by arranging the motor fixing seat 31 and the bearing base 32 on the same straight line, since the motor fixing seat 31 and the bearing base 32 are arranged on the same straight line, when the rotating shaft and the bearing are pressed together: the power output end of the pushing mechanism 20 is ejected, and the sliding plate 3 is driven to move toward the rotating circular plate 1 until the bearing base 32 on the sliding plate 3 is aligned with the blanking through hole 11 (that is, the central axis of the blanking through hole 11 and the central axis of the bearing base 32 are both located on the same central axis). In the process of aligning the blanking through hole 11, since the bearing base 32 is close to the outside of the blanking baffle 12, the bearing base 32 will retract the blanking plate, and the single bearing at the blanking through hole 11 will fall to the top of the bearing base 32. It should be noted that It is worth noting that at this time, the motor fixing seat 31 is aligned with the pressing manipulator, and the motor rotor grabbed by the pressing manipulator can be placed on the motor fixing seat 31 and then raised, and the power output end of the pushing mechanism 20 retracts, driving the sliding plate 3 to retreat until the bearing base 32 on the sliding plate 3 is aligned with the pressing mechanism, and the single bearing picking action is completed, which can facilitate the pressing manipulator to grab a single bearing on the bearing base 32 and move it to the motor fixing seat 31 to align with the rotor shaft to perform the bearing pressing action at one end of the shaft. After the bearing is pressed at one end of the rotor shaft, the pressing manipulator can grab and lift the motor rotor on the motor fixing seat 31. At this time, the power output end of the pushing mechanism 20 is extended again, driving the sliding plate 3 to move toward the rotating circular plate 1 again to pick up the material;

[0048] When the material is taken, the power output end of the pushing mechanism 20 retracts again, and the bearing base 32 is aligned with the rotor shaft on the pressing robot again. The pressing robot descends again to press the bearing at the other end of the rotor shaft, thereby facilitating the pressing of the bearings at both ends of the rotor shaft. Circular through holes are provided at the center of the motor fixing seat 31 and the bearing base 32, and the circular through holes are used for inserting the shaft, thereby ensuring that the shaft can extend into the circular through hole during the pressing process.

[0049] It should be noted that in order to prevent the bearing base 32 on the sliding plate 3 from directly colliding with the rotating circular plate 1, in this embodiment: by evenly distributing a number of material collection openings 14 on the outside of the rotating circular plate 1, the several material collection openings 14 are matched one by one with the several blanking holes 11, and the bearing base 32 on the sliding plate 3 can completely enter the bottom of the rotating circular plate 1 and can be aligned with the blanking holes 11, and a number of material collection openings 14 can be evenly distributed on the outside of the rotating circular plate 1, and then when one end of the sliding plate 3 moves toward the rotating circular plate 1, the bearing base 32 on the sliding plate 3 will not collide with the outside of the rotating circular plate 1, which effectively facilitates the bearing base 32 to enter the bottom of the rotating circular plate 1 and align with the blanking holes 11 to perform the material collection action, and then the several material collection openings 14 can be used for the bearing base 32 to enter.

[0050] It should also be noted that in order to fix the bearing during the material removal process and facilitate the bearing to be fixed on the bearing base 32, a limiting tube body 321 is provided on the top of the bearing base 32, the outer diameter of the limiting tube body 321 is adapted to the inner diameter of the bearing, and the height of the limiting tube body 321 is consistent with the height of the bearing, so that multiple bearings can be prevented from falling onto the bearing base 32. An arc-shaped bayonet is provided on the side of the blanking baffle 12 facing the limiting tube body 321, so that the rotor shaft can be pressed onto the bearing base 32. When the shaft is completely placed in the limiting tube body 321, the limiting tube body 321 is used to facilitate the pressing robot to place the shaft, and the shaft can also be placed vertically through the inside of the limiting tube body 321. At this time, the pressing machine completes the pressing of the bearing at one end of the rotor shaft. When the bearing needs to be pressed on the other end of the rotor shaft, the pressing robot grabs the bearing that has completed the pressing of one end, and then the pressing robot grabs the rotor shaft again and aligns the bearing on the bearing base 32 again, and performs the bearing pressing action on the other end of the rotor shaft.

[0051] Example 2

[0052] In order to realize the continuous bearing feeding action during the process of continuous pressing of bearings and rotating shafts to produce motors, in this embodiment: a rotating motor 13 is arranged directly below the rotating circular plate 1, and the power output end of the rotating motor 13 is fixed to the bottom of the rotating circular plate 1, thereby realizing that the rotating motor 13 is used to control the rotation direction of the rotating circular plate 1, so that the rotating motor 13 drives the rotating circular plate 1 to rotate counterclockwise and / or clockwise, and a plurality of feeding rods 10 are evenly distributed on the top of the rotating circular plate 1, and a plurality of bearings are stacked on the outside of each feeding rod 10, and a plurality of blanking through holes 11 are evenly distributed on the surface of the rotating circular plate 1, and the ends of the plurality of feeding rods 10 are connected to the plurality of blanking through holes. 11 correspond one to one, thereby ensuring that the bearings on the feeding rod 10 slide down to the blanking holes 11 through the feeding rod 10 in turn, by movably providing blanking baffles 12 at the bottom of several blanking holes 11, so that one side of the blanking baffle 12 faces the rotating circular plate 1, and then the bearings at the blanking holes 11 can be blocked by the blanking baffle 12, and the bearing picking action can be performed by pushing the blanking baffle 12. When the blanking of multiple bearings on a single feeding rod 10 aligned with the sliding plate 3 is completed, the rotating motor 13 is started and drives the rotating circular plate 1 to rotate, so that the next adjacent feeding rod 10 is aligned with the sliding plate 3 again, effectively realizing the action of continuous feeding of bearings, which can be suitable for batch continuous production of motor rotors.

[0053] Example 3

[0054] In order to clamp and fix the bearing after taking the material, ensure that the bearing does not produce position deviation, and thus facilitate the concentricity of the rotating shaft and the bearing during the subsequent pressing process of the rotating shaft and the bearing, in this embodiment: a sliding plate 3 and a mounting plate 2 are provided, the sliding plate 3 is located directly above the mounting plate 2, and the sliding plate 3 is also slid on the mounting plate 2 so that one end of the sliding plate 3 is aligned with the rotating circular plate 1, and a pushing mechanism 20 is provided on the mounting plate 2, and the power output end of the pushing mechanism 20 is connected to the other end of the sliding plate 3. Thus, the pushing mechanism 20 is used to control the moving distance of the sliding plate 3, and the sliding plate 3 can be driven by the pushing mechanism 20 to move toward the rotating circular plate 1. By respectively providing a motor fixing seat 31 and a bearing base 32 just above the sliding plate 3, the bearing base 32 is provided on the outside of the blanking baffle 12, and then the bearing base 32 can be used to place the bearing to be pressed, and the motor fixing seat 31 can be used to place the motor rotor, and the bearing base 32 is used to take the material close to the rotating circular plate 1. The specific taking action can be referred to the description of the first embodiment;

[0055] By symmetrically arranging a clamping mechanism 4 on both sides of the outside of the mounting plate 2, the clamping mechanism 4 includes a clamping plate 42 and a clamping cylinder 41, connecting one side of the clamping plate 42 to the power output end of the clamping cylinder 41, and also facing the other side of the clamping plate 42 to the bearing base 32, and then the clamping plate 42 can be pushed toward the bearing base 32 by the clamping cylinder 41. When the bearing base 32 carries a single bearing, the clamping plate 42 moves toward the single bearing on the bearing base 32 until the clamping plate 42 abuts against the outside of the single bearing, thereby achieving the effect of clamping the bearing, and effectively preventing the bearing from being displaced and loose.

[0056] It should be noted that, in order to ensure a secure clamping, an arcuate groove 421 is provided on the side of the clamping plate 42 facing the bearing base 32, and the arcuate groove 421 is adapted to the outside of the bearing. When the sliding plate 3 drives the bearing base 32 to align with the two sets of clamping mechanisms, the clamping plates 42 of the two sets of clamping mechanisms are aligned with the bearings on the bearing base 32, and the clamping cylinder 41 drives the clamping plate 42 toward the bearing on the bearing base 32 until the side of the clamping plate 42 facing the bearing base 32 abuts against the bearing. The bearing on the bearing base 32 is clamped by the arc-shaped groove to prevent the bearing from shifting during the pressing of the rotating shaft into the bearing, thereby ensuring the concentricity of the rotating shaft and the bearing. In addition, an arc opening 422 is provided at the top of the arc-shaped groove 421 so that the arc opening 422 is connected to the arc-shaped groove 421. During the pressing process of the rotating shaft to align with the bearing, the rotating shaft can enter the arc-shaped groove 421 through the arc opening 422 and pass through the inside of the bearing, and fit with the outer wall of the rotating shaft through the side of the arc opening 422 facing the rotating shaft.

[0057] It should also be noted that when the clamping plates 42 of the two clamping mechanisms 4 are fitted together, the two arc-shaped grooves 421 merge with each other to form a clamping circular hole for the bearing to be placed in, and the two arc openings 422 merge with each other to form a pressing circular hole for the shaft to be placed in. The central axis of the pressing circular hole and the central axis of the clamping circular hole are both located on the same central axis. By arranging the two clamping mechanisms 4 symmetrically on both sides of the outside of the mounting plate, when the clamping cylinders 41 of the two clamping mechanisms 4 respectively drive the two clamping plates 42 to move toward each other, the two clamping plates 42 can be moved to the same position. During movement, the two clamping plates 42 move toward the bearing base 32 until the two clamping plates 42 abut and clamp the two sides of the outer side of the bearing on the bearing base 32. Since the clamping plates 42 are provided with an arc-shaped groove 421 on the side facing the bearing base 32, and the arc-shaped groove 421 is adapted to the outer side of the bearing, the bearing can be fixed by the arc-shaped groove 421, and the circular arc opening 422 provided on the top of the arc-shaped groove 421 is convenient for the insertion of the rotating shaft, so that the rotating shaft and the bearing can be pressed together.
