The translation slide is then allowed to move to the left. At this time, the retaining spring can be driven to be sleeved on the rotor. When the retaining spring reaches the correct position, the two retaining spring pins are allowed to detach from the retaining spring, and the two telescopic rods III are recovered. At this time, the translation slide moves to the right, and the installation of the rotor retaining spring is completed.

[0004] During the conception process, the applicant searched a large number of patent documents on the patent network. For example, Chinese patent publication number CN111843446B discloses a "motor rotor retaining spring assembly machine". When assembling the retaining spring, only one rotor can be fixed at a time, and the staff needs to frequently fix and disassemble the rotor. The operation steps are relatively cumbersome, resulting in low work efficiency. Therefore, a motor rotor retaining spring assembly machine is proposed to solve the above-mentioned problems.

An upper feeding component 2 is arranged on the operating table 1. The upper feeding component 2 includes a first hydraulic cylinder 21. The first hydraulic cylinder 21 is installed on the operating table 1. The output end of the first hydraulic cylinder 21 is connected to a top plate 22. A baffle 23 is installed on the top plate 22. A material trough 24 is installed on the operating table 1. An elastic push plate 25 is slidably installed on the material trough 24 through a spring. A guide plate 26 is installed on the operating table 1. The staff sequentially installs a plurality of rotors in the material trough 24. Due to the elastic force of the elastic push plate 25, the elastic push plate 25 applies a forward pressure to the plurality of rotors. The first rotor at the forefront is placed in the guide plate 26. An installation component 3 is arranged on the operating table 1. The installation component 3 includes a base 31. The base 31 is installed on the operating table 1. A second hydraulic cylinder 32 is installed on the inner wall of the base 31. The output end of the second hydraulic cylinder 32 is connected to an installation rod 33. A fixing component 4 is arranged on the operating table 1. The fixing component 4 includes an installation seat 41. The installation seat 41 is installed on the operating table 1. A limiting groove 42 is arranged on the installation seat 41. A resilient column 43 is slidably installed on the limiting groove 42. A fitting pipe 44 is installed on the installation seat 41. A piston 45 is slidably installed in the inner wall of the fitting pipe 44 through a spring. The staff installs a plurality of snap rings in the fitting pipe 44 in advance. Due to the elastic force of the spring on the piston 45, the piston 45 applies a pressure to the plurality of snap rings, so that the first snap ring at the rightmost end of the fitting pipe 44 abuts against an oil tank 51. A lubricating component 5 is arranged on the operating table 1. The lubricating component 5 includes an oil tank 51. The oil tank 51 is installed on the operating table 1. The right side of the oil tank 51 is connected to the guide plate 26. The left side of the oil tank 51 is connected to the fitting pipe 44. A limiting hole is arranged on the oil tank 51. Start the first hydraulic cylinder 21. The first hydraulic cylinder 21 drives the top plate 22 to move leftward. The top plate 22 pushes the first rotor to move leftward. During the process of the rotor moving leftward, the rotating shaft on the rotor first passes through the limiting hole on the oil tank 51, and then contacts the resilient column 43 and pushes the resilient column 43 leftward. At this time, the rotating shaft contacts the limiting groove 42 on the installation seat 41. The limiting groove 42 cooperates with the limiting hole to limit and fix the rotor. At this time, start the second hydraulic cylinder 32. The second hydraulic cylinder 32 drives the installation rod 33 to move forward on the base 31. During the movement of the installation rod 33, it first contacts the first snap ring and pushes the first snap ring forward. During the forward movement of the snap ring, it contacts the rotating shaft and is installed on the rotating shaft under the pressure of the installation rod 33. At this time, the first snap ring has been installed on the first rotor. Close the first hydraulic cylinder 21 and the second hydraulic cylinder 32. After the second hydraulic cylinder 32 drives the installation rod 33 to reset, the second snap ring moves rightward under the thrust of the piston 45 and abuts against the oil tank 51. When the top plate 22 moves leftward, the top plate 22 drives the baffle 23 to move synchronously. The baffle 23 blocks the second rotor from entering the guide plate 26. When the top plate 22 resets, the second rotor moves forward to the guide plate 26 under the elastic force of the elastic push plate 25.At this time, the above steps can be repeated to assemble the second rotor and the second snap ring.

[0025] In this embodiment, through the cooperation of the feeding assembly 2, the installation assembly 3 and the fixing assembly 4, the staff can install multiple snap rings and multiple rotors in the fitting pipe 44 and the material tank 24 in advance. During the assembly operation, through the cooperation of the first hydraulic cylinder 21 and the second hydraulic cylinder 32, the assembly of the rotor and the snap ring is completed, and during the assembly process, there is no need for the staff to position and fix the rotor and the snap ring again. After a set of rotor and snap ring is assembled, the next set of rotor and snap ring will be automatically in place and wait for the next assembly, reducing the operation of the staff to position and fix the rotor and the snap ring, and improving the work efficiency through cyclic assembly.

[0026] Embodiment 2

[0027] Please refer to Figure 5 As shown, an airbag 52 is installed on the fuel tank 51, a fuel pipe 53 is installed in the fuel tank 51, an oil injector 54 is installed on the limit hole of the fuel tank 51, and the oil injector 54 is connected to the fuel pipe 53. During the process of the rotor moving to the left, the rotating shaft will contact the oil injector 54 in the limit hole of the fuel tank 51, and the oil injector 54 will apply grease to the rotating shaft, which is convenient for the subsequent installation of the snap ring. When the rotor moves to the left in place, the rotor will contact and squeeze the airbag 52, and the airbag 52 will inject air into the fuel tank 51 after being squeezed. The fuel tank 51 will send part of the grease to the oil injector 54 through the fuel pipe 53 under the action of positive pressure, so as to maintain the saturation of the grease on the oil injector 54.

[0028] In this embodiment, through the setting of the lubrication assembly 5, during the process of the rotor moving to the left, the oil injector 54 can apply grease to the rotating shaft on the rotor. After the rotating shaft is coated with grease, it is more conducive to installation, avoiding damage to some snap rings due to excessive friction during the assembly with the rotor, and the fuel tank 51 can continuously supplement the grease to the oil injector 54 through the fuel pipe 53 during the assembly operation to maintain the saturation of the grease on the oil injector 54, so as to ensure the lubrication effect.

[0029] When a motor rotor snap ring assembling machine of the utility model is in use, the staff installs a plurality of snap rings in the fitting pipe 44 in advance. Due to the elastic force of the spring on the piston 45, the piston 45 applies pressure to the plurality of snap rings, so that the first snap ring at the rightmost end of the fitting pipe 44 abuts against the fuel tank 51. The staff installs a plurality of rotors in the material groove 24 in sequence. Due to the elastic force of the elastic push plate 25, the elastic push plate 25 applies a forward pressure to the plurality of rotors, and the first rotor at the forefront is placed in the guiding plate 26. The first hydraulic cylinder 21 is started, and the first hydraulic cylinder 21 drives the top plate 22 to move leftward. The top plate 22 pushes the first rotor to move leftward. During the process of moving leftward, the rotating shaft on the rotor first passes through the limiting hole on the fuel tank 51, and then contacts the return spring column 43 and pushes the return spring column 43 leftward. At this time, the rotating shaft contacts the limiting groove 42 on the mounting seat 41, and the limiting groove 42 cooperates with the limiting hole to limit and fix the rotor. At this time, the second hydraulic cylinder 32 is started, and the second hydraulic cylinder 32 drives the mounting rod 33 to move forward on the base 31. During the movement of the mounting rod 33, it first contacts the first snap ring and pushes the first snap ring forward. During the forward movement of the snap ring, it contacts the rotating shaft and is installed on the rotating shaft under the pressure of the mounting rod 33. At this time, the first snap ring has been installed on the first rotor. The first hydraulic cylinder 21 and the second hydraulic cylinder 32 are closed. After the second hydraulic cylinder 32 drives the mounting rod 33 to reset, the second snap ring moves rightward due to the thrust of the piston 45 and abuts against the fuel tank 51. When the top plate 22 moves leftward, the top plate 22 drives the baffle 23 to move synchronously, and the baffle 23 blocks the second rotor from entering the guiding plate 26. When the top plate 22 resets, the second rotor moves forward to the guiding plate 26 due to the elastic force of the elastic push plate 25. At this time, the above steps can be repeated to assemble the second rotor and the second snap ring. Through the cooperation of the feeding assembly 2, the installation assembly 3 and the fixing assembly 4, the staff can install a plurality of snap rings and a plurality of rotors in the fitting pipe 44 and the material groove 24 in advance. During the assembly operation, through the cooperation of the first hydraulic cylinder 21 and the second hydraulic cylinder 32, the assembly of the rotor and the snap ring is completed, and during the assembly process, there is no need for manual re-positioning and fixing of the rotor and the snap ring. After a group of rotors and snap rings are assembled, the next group of rotors and snap rings will automatically be in place and wait for the next assembly, reducing the operation of the staff for positioning and fixing the rotor and the snap ring. Through the cyclic assembly, the working efficiency is improved.

[0030] During the process of the rotor moving to the left, the rotating shaft will come into contact with the lubricator 54 in the upper limit hole of the fuel tank 51. The lubricator 54 applies grease to the rotating shaft, facilitating the subsequent installation of the snap ring. When the rotor moves to the left in place, the rotor will contact and squeeze the airbag 52. After being squeezed, the airbag 52 injects air into the fuel tank 51. Through the positive pressure effect, the fuel tank 51 transports part of the grease to the lubricator 54 through the oil pipe 53, thereby maintaining the saturation of the grease on the lubricator 54. Through the setting of the lubrication assembly 5, during the process of the rotor moving to the left, the lubricator 54 can apply grease to the rotating shaft on the rotor. After the rotating shaft is coated with grease, it is more conducive to installation, avoiding damage to some snap rings due to excessive friction during the assembly process with the rotor. Moreover, the fuel tank 51 can continuously supplement the grease to the lubricator 54 through the oil pipe 53 during the assembly operation, maintaining the saturation of the grease on the lubricator 54, thus ensuring the lubrication effect.

Those of ordinary skill in the relevant technical fields can still make various changes and modifications without departing from the spirit and scope of the embodiments of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the embodiments of the present invention.
