Description

Technical Field

[0001] This utility model relates to the field of motor rotor cleaning technology, specifically to a cleaning structure for a rotor hoisting cleaning basket. Background Technology

[0002] An electric motor consists of two parts: a rotor and a stator. The rotor usually refers to the rotating part of the motor and is generally divided into two types: motor rotor and generator rotor. Brazing of the rotor end ring is a special welding technique in the rotor production process. It is mainly used to connect the motor rotor end ring to the guide bar. After welding, cleaning is required to remove residual flux. Cleaning methods include using deionized water, cleaning agents, and ultrasonic cleaning.

[0003] Currently, when cleaning motor rotors, the rotor needs to be fixed. There are several cleaning methods. The first is water planing cleaning (suitable for high-temperature conditions), which is done manually by suspending the rotor in a tap water tank and using a wire brush to clean the flux on the rotor end rings to ensure thorough removal of residues. The second is ordinary cleaning (suitable for room temperature conditions). After the rotor brazing has cooled to room temperature, the rotor core is placed flat on the drive roller frame of the cleaning machine. A neutral cleaning agent is used, ensuring that the cleaning agent is compatible with the flux. The cleaning is carried out for 6 to 15 minutes at a water temperature above 35°C. The above cleaning processes require constant adjustment of the motor rotor cleaning angle, resulting in low cleaning efficiency. In addition, the rotor has many blind spots under these cleaning methods, which can easily lead to incomplete cleaning. Utility Model Content

[0004] To address the technical deficiencies in the background art, this utility model proposes a cleaning structure for a rotor hoisting cleaning basket, which solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows:

[0005] A cleaning structure for a rotor-lifting cleaning basket includes a cleaning basket, a cleaning tank, and a lifting mechanism disposed on the side of the cleaning tank. A first driving device is connected to the upper edge of the lifting mechanism. A lifting bracket is provided on one end face of the lifting mechanism facing the cleaning tank. The lifting bracket is connected to the upper edge of the cleaning basket. A second driving device is connected to the bottom of the cleaning tank. A rotating base is provided at the bottom of the cleaning tank. The rotating base is connected to the output end of the second driving device. The end face of the rotating base is provided with an upward-opening rotating groove.

[0006] As an improvement to the above solution, there are two lifting mechanisms, which are symmetrically arranged on both sides of the cleaning tank, and the output end of the first drive device is connected to the transmission end of the two lifting mechanisms respectively.

[0007] As an improvement to the above solution, the lifting mechanism includes a guide base, a guide rod, a transmission screw, and a lifting bracket. The guide base is vertically arranged on both sides of the cleaning tank. The guide rod and the transmission screw both extend along the length direction of the guide base. The lifting bracket is sleeved on the guide rod and the transmission screw.

[0008] As an improvement to the above solution, the end face of the guide base facing the cleaning tank is provided with two guide rods. The guide rods are symmetrically arranged along the central axis of the guide base in the width direction. The transmission screw is clamped between the two guide rods and aligned with the central axis of the guide base in the width direction. One end of the transmission screw is connected to the output end of the first drive device.

[0009] As an improvement to the above solution, the lifting bracket is provided with a guide hole passing through the guide rod along its thickness direction at the position corresponding to the position of the guide rod, and a threaded hole passing through the transmission screw along its thickness direction at the position corresponding to the position of the transmission screw.

[0010] As an improvement to the above solution, the end face of the lifting bracket facing the cleaning tank is provided with an L-shaped connecting bracket one, and the side of the cleaning basket corresponding to the lifting bracket is provided with an inverted L-shaped connecting bracket two. The positions and quantities of the connecting bracket one and the connecting bracket two are matched.

[0011] As an improvement to the above solution, the first drive device includes a geared motor, a coupling, a steering gear, and a transmission rod. The output end of the geared motor is connected to the steering gear, and a coupling is provided between the transmission rod and the steering gear.

[0012] As an improvement to the above solution, the cleaning basket is composed of several support rods, and the bottom of the cleaning basket is arranged in a nine-square grid shape with horizontally arranged support rods and vertically arranged support rods. The middle part of the cleaning basket is aligned with the rotating base.

[0013] The beneficial effects of this utility model are as follows: the first driving device drives the cleaning basket to carry the rotor into the cleaning tank, the ultrasonic system is activated, and the surface flux of the rotor is cleaned by ultrasonic waves. After cleaning, the first driving device controls the rotor to fall so that the end of the rotor is placed in the rotating groove. The second driving device drives the rotor to rotate slowly, which drives the water flow to rotate and accelerate the removal of flux adsorbed on the surface of the rotor. This solves the problem of unclean cleaning of the dead corner of the rotor, improves the cleaning effect of the rotor, reduces the manual input, and has a better cleaning effect.

[0019] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0020] like Figures 1 to 4 As shown, a cleaning structure for a rotor-lifting cleaning basket includes a cleaning basket 1, a cleaning tank 2, and a lifting mechanism 4 disposed on the side of the cleaning tank 2. A first driving device 5 is connected to the upper edge of the lifting mechanism 4. A lifting bracket 401 is provided on the side end face of the lifting mechanism 4 facing the cleaning tank 2. The lifting bracket 401 is connected to the upper edge of the cleaning basket 1. A second driving device 6 is connected to the bottom of the cleaning tank 2. A rotating base 201 is provided at the bottom of the cleaning tank 2. The rotating base 201 is connected to the output end of the second driving device 6. The end face of the rotating base 201 is provided with an upward-opening rotating groove 3.

[0021] like Figure 1 and Figure 3As shown, in the structure of the lifting mechanism 4 of this utility model, there are two lifting mechanisms 4, which are symmetrically arranged on both sides of the cleaning tank 2. They are used to lift the two sides of the cleaning basket 1 respectively. The output end of the first drive device 5 is connected to the transmission end of the two lifting mechanisms 4 respectively. The first drive device 5 drives and controls the horizontal height of the cleaning basket 1. During cleaning, the lifting mechanisms 4 on both sides of the cleaning basket 1 control the cleaning basket 1 to descend horizontally into the cleaning tank 2. The rotor is ultrasonically cleaned by the ultrasonic cleaning system. After cleaning is completed, the lifting mechanism 4 controls the cleaning basket 1 to rise horizontally and lift the rotor out of the cleaning tank 2.

[0022] like Figure 3 As shown, further, in the above scheme, the lifting mechanism 4 includes a guide base 402, a guide rod 403, a transmission screw 404, and a lifting bracket 401. The guide base 402 is vertically arranged on both sides of the cleaning tank 2. The guide rod 403 and the transmission screw 404 both extend along the length direction of the guide base 402. The lifting bracket 401 is sleeved on the guide rod 403 and the transmission screw 404. The lifting bracket 401 has a guide hole 4011 corresponding to the position of the guide rod 403, which is inserted along its thickness direction. The guide hole 4011 is used to guide the movement direction of the lifting bracket 401 and restrict the axial degree of freedom of the lifting bracket 401. A threaded hole 4012 corresponding to the position of the transmission screw 404 is provided along its thickness direction. By rotating the transmission screw 404 clockwise or counterclockwise, the lifting bracket 401 is controlled to reciprocate along the length direction of the transmission screw 404.

[0023] Furthermore, in the above scheme, the end face of the guide base 402 facing the cleaning tank 2 is provided with two guide rods 403. The guide rods 403 are symmetrically arranged along the central axis of the width direction of the guide base 402. The transmission screw 404 is sandwiched between the two guide rods 403 and aligned with the central axis of the width direction of the guide base 402. One end of the transmission screw 404 is connected to the output end of the first driving device 5. The transmission screw 404 is driven to rotate through the output end of the first driving device 5, thereby achieving the technical effect of controlling the lifting bracket 401 to rise and fall.

[0024] It should be noted that during the cleaning process of this application, after the rotor is placed in the cleaning basket 1, the bottom end of the rotor extends downward from the support rod 102 of the cleaning basket 1. The first driving device 5 drives the transmission screw 404 to rotate counterclockwise, causing the lifting bracket 401 to move downward, that is, causing the cleaning basket 1 to move towards the cleaning tank 2. When the liquid in the cleaning tank 2 covers the top of the rotor and the bottom end of the rotor is not in contact with the rotating base, the first driving device 5 controls the transmission screw 404 to stop rotating and starts the ultrasonic cleaning system to perform ultrasonic cleaning on the rotor.

[0025] like Figure 4 As shown, further, after the ultrasonic cleaning process is completed, the first driving device 5 drives the transmission screw 404 to rotate counterclockwise for the second time, causing the lifting bracket 401 to move downward, that is, causing the cleaning basket 1 to move towards the cleaning tank 2, so that the bottom end of the rotor is placed in the rotating groove 3, and the cleaning basket 1 continues to move downward until it is no longer in contact with the rotor. The first driving device 5 then controls the transmission screw 404 to stop rotating, and starts the second driving device 6 to drive the rotating base 201 to rotate slowly, causing the rotor to rotate slowly in the water, causing the water flow to rotate, accelerating the removal of flux adsorbed on the rotor surface, solving the problem of unclean cleaning of the rotor dead corners, and improving the cleaning effect of the rotor.

[0026] like Figures 1 to 3 As shown, further, in the above scheme, the end face of the lifting bracket 401 facing the cleaning tank 2 is provided with an L-shaped connecting bracket 405, and the side of the cleaning basket 1 corresponding to the lifting bracket 401 is provided with an inverted L-shaped connecting bracket 101. The positions and quantities of the connecting bracket 405 and the connecting bracket 101 are matched, and the lifting bracket 401 is connected to the connecting bracket 101 on the cleaning basket 1 through the connecting bracket 405.

[0027] like Figure 1 As shown, further, in the above scheme, the first drive device 5 includes a geared motor 501, a coupling 502, a steering gear 503, and a transmission rod 504. The output end of the geared motor 501 is connected to the steering gear 503 by a transmission rod 504. The transmission rod 504 is connected to the steering gear 503 by a coupling 502. In a specific configuration, the user can achieve synchronous driving between two transmission rods 504 with different shaft alignment by setting the steering gear 503 and the coupling 502 between two adjacent transmission rods 504 in the installation structure of the first drive device 5.

[0028] like Figure 2As shown, further, in the above scheme, the cleaning basket 1 is composed of several support rods 102. The bottom of the cleaning basket 1 is arranged in a nine-square grid shape by the horizontally arranged support rods 102 and the vertically arranged support rods 102. The middle part of the cleaning basket 1 is aligned with the rotating base 201 in the square corresponding to the corner position of the outer edge of the cleaning basket 1.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
