Description

Technical Field

[0001] The invention relates to the technical field of motor rotor cleaning, in particular to a cleaning device after the outer cylindrical grinding of the motor rotor. Background Art

[0002] The motor rotor is an important part of the motor. Due to the high speed of high-power density and high-speed motors, the outer circle of the magnetic steel of the rotor assembly needs to be ground and then covered with a stainless steel sheath to ensure reliable high-speed operation of the motor. The sheath of the rotor assembly is bonded to the outer circle of the shaft with a retaining adhesive. After grinding, a large amount of oil and magnetic powder will be attached to the outer circle. If the oil and excess are not cleaned thoroughly, it will affect the bonding of the sheath and bring excess matter into the motor, which will cause great quality risks.

[0003] At present, the cleaning of motor rotors is mostly done manually, that is, the operator holds a cleaning brush and dips it in cleaning liquid for cleaning, but the efficiency of manual cleaning is low. In order to improve the cleaning efficiency, some rotor cleaning devices have emerged, such as the patent application with publication number CN106623013A, which discloses a motor rotor cleaning device. A circular track can be laid on the ground for rotor cleaning. The circular track cooperates with the track wheel on the cleaning device. The track wheel rolls along the track so that the entire cleaning device can make a circular motion to clean the rotor for one week. When in use, start the lifting hydraulic cylinder to move the cleaning brush to the required height and make the cleaning brush contact with the rotor surface, then turn on the cleaning agent supply module to fill the cleaning brush with cleaning liquid through the infusion pipeline, and then move the carrier to make the cleaning device move in a circle around the rotor. After one week, the cleaning brush is moved up or down a certain distance by the lifting hydraulic cylinder and the above actions are repeated until the entire rotor surface is cleaned.

[0004] However, when the device in the prior art CN106623013A is used, a circular track needs to be laid on the ground for cleaning the rotor, which makes the operation more complicated and the circular track occupies the plant space. Summary of the invention

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0029] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0030] As shown in the accompanying drawings, a cleaning device for motor rotor after external cylindrical grinding includes a cabinet, a table 12 is arranged inside the cabinet, the table 12 divides the inner cavity of the cabinet into a lower cavity 1a and an upper cavity 1b, a synchronous belt module 2 and a cleaning component 4 are installed on the table 12; a rotary clamping component 3 is installed on the slider 203 of the synchronous belt module 2; the cleaning component 4 includes a brush 440; the rotary clamping component 3 is used to clamp the workpiece 7 and drive the workpiece 7 to rotate around its own axis; the synchronous belt module 2 is used to drive the rotary clamping component 3 to translate so that the workpiece 7 is in contact with or away from the brush 440.

[0031] Combination Figure 3 As shown, the synchronous belt module 2 includes a mold base, a translation stepper motor 200, a second coupling 201 and a slider 203; pulleys are provided inside the two ends of the mold base, and a synchronous belt 202 is sleeved between the two pulleys. The slider 203 is slidably mounted on the mold base, and the slider 203 is connected to the synchronous belt 202. The translation stepper motor 200 is connected to one of the active pulleys inside the mold base through the second coupling 201. When the translation stepper motor 200 is started, the active pulley inside the mold base is driven to rotate through the second coupling 201 to move the synchronous belt 202, and then the slider 203 is driven to slide on the mold base. Therefore, the synchronous belt module 2 can drive the rotating clamping assembly 3 to perform translational movement. The synchronous belt module 2 is a conventional existing structure and will not be described in detail here.

[0032] By adopting the above structure, when cleaning the motor rotor workpiece 7, the workpiece 7 to be cleaned is clamped on the rotating clamping assembly 3, and the rotating clamping assembly 3 is used to drive the workpiece 7 to rotate around its own axis. At the same time, the synchronous belt module 2 drives the rotating clamping assembly 3 to translate so that the workpiece 7 contacts the brush 440, thereby achieving the purpose of cleaning the oil stains and stubborn magnetic powder excess attached to the outer surface of the workpiece 7. After the cleaning is completed, the synchronous belt module 2 drives the rotating clamping assembly 3 to translate so that the workpiece 7 is separated from the brush 440, and the workpiece 7 can be removed from the rotating clamping assembly 3.

[0033] Combination Figure 2As shown, in order to prevent splashing caused by oil and stubborn magnetic powder on the workpiece 7 during the cleaning process, a protective cover 10 is installed on the table 12, and the cleaning component 4 is arranged in the inner cavity of the protective cover 10. Specifically, the lower end of the protective cover 10 is fixed on the table 12, the front of the protective cover 10 is open, and a U-shaped opening 10a is opened on one side wall of the protective cover 10. When the synchronous belt module 2 drives the rotating clamping component 7 to translate so that the workpiece 7 moves, the U-shaped opening 10a is used to avoid interference with the workpiece 7.

[0034] Combination Figure 4 As shown, a plasma blower 40 is provided on the lower surface of the top plate of the protective cover 10, and the plasma blower 40 is arranged at intervals just above the brush 440.

The brush 440 dips the cleaning liquid in this way, which can ensure that the cleaning liquid is uniform and controllable. During operation, since the brush 440 is dipped in cleaning liquid and used to clean the workpiece 7, the cleaning effect is further improved.

[0038] In this embodiment, the cleaning equipment further includes a cleaning liquid storage tank (not shown in the figure); a pipe joint 40 is provided on the top of the cleaning liquid spray box 42; a peristaltic pump 45 is provided on the table 12; the peristaltic pump 45 and the pipe joint 40 are connected by a pipeline (the pipeline is not shown), and a liquid inlet pipe (not shown in the figure) is provided on the peristaltic pump 45, and the inlet end of the liquid inlet pipe is connected to the cleaning liquid storage tank.
