Description

Technical Field

[0001] This invention relates to the field of motor rotor cleaning technology, and in particular to a cleaning device for the outer diameter of a motor rotor after grinding. Background Technology

[0002] The motor rotor is a crucial component of the motor. Due to the high speed of high-power-density, high-speed motors, the outer circumference of the magnets in the rotor assembly needs to be ground before being fitted with a stainless steel sleeve to ensure reliable high-speed operation. The sleeve of the rotor assembly is bonded to the outer circumference of the shaft with adhesive. After grinding, a large amount of oil and magnetic powder residue will adhere to the outer circumference. Incomplete cleaning of the oil and residue will affect the adhesion of the sleeve and will also introduce foreign matter into the motor, posing a significant quality hazard.

[0003] Currently, motor rotor cleaning is mostly done manually, with workers using hand-held cleaning brushes dipped in cleaning solution. However, manual cleaning is inefficient. To improve cleaning efficiency, some rotor cleaning devices have emerged. For example, patent application CN106623013A 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 wheels on the cleaning device. The track wheels roll along the track, allowing the entire cleaning device to perform a circular motion, cleaning one revolution of the rotor. In use, the lifting hydraulic cylinder is activated to move the cleaning brush to the required height and make it contact the rotor surface. Then, the cleaning agent supply module is turned on to saturate the cleaning brush with cleaning solution through the infusion pipeline. The support frame is then moved to make the cleaning device rotate around the rotor. After one revolution, the lifting hydraulic cylinder is used to move the cleaning brush up or down a certain distance, and the above actions are repeated until the entire rotor surface is cleaned.

[0004] However, the device in the prior art CN106623013A requires a circular track to be laid on the ground where the rotor is being cleaned, making the operation cumbersome and the circular track occupies factory space. Summary of the Invention

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

If the specific posture changes, the directional indication will also change accordingly.

[0029] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0030] As shown in the accompanying drawings, a cleaning device for the outer diameter of a motor rotor after grinding includes a cabinet. A table 12 is provided inside the cabinet, dividing the cabinet's interior into a lower cavity 1a and an upper cavity 1b. A synchronous belt module 2 and a cleaning assembly 4 are mounted on the table 12. A rotary clamping assembly 3 is mounted on the slider 203 of the synchronous belt module 2. The cleaning assembly 4 includes a brush 440. The rotary clamping assembly 3 is used to clamp a 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 assembly 3 to translate so that the workpiece 7 contacts or moves away from the brush 440.

[0031] Combination Figure 3 As shown, the synchronous belt module 2 includes a mold base, a translational stepper motor 200, a second coupling 201, and a slider 203. Pulleys are installed inside both ends of the mold base, and a synchronous belt 202 is fitted between the two pulleys. The slider 203 is slidably mounted on the mold base and connected to the synchronous belt 202. The translational stepper motor 200 is connected to one of the drive pulleys inside the mold base via the second coupling 201. When the translational stepper motor 200 starts, it drives the drive pulley inside the mold base to rotate via the second coupling 201, causing the synchronous belt 202 to move, which in turn drives the slider 203 to slide on the mold base. Therefore, the synchronous belt module 2 can drive the rotary 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 employing the above structure, when cleaning the motor rotor workpiece 7, the workpiece 7 to be cleaned is clamped on the rotary clamping assembly 3, and the rotary clamping assembly 3 drives the workpiece 7 to rotate around its own axis. At the same time, the synchronous belt module 2 drives the rotary clamping assembly 3 to translate, so that the workpiece 7 comes into contact with the brush 440, thereby achieving the purpose of cleaning the oil stains and stubborn magnetic powder residues adhering to the outer surface of the workpiece 7. After cleaning, the synchronous belt module 2 drives the rotary clamping assembly 3 to translate, so that the workpiece 7 separates from the brush 440, and the workpiece 7 can be removed from the rotary clamping assembly 3.

[0033] Combination Figure 2As shown, to prevent oil stains and stubborn magnetic powder on the workpiece 7 from splashing during the cleaning process, a protective cover 10 is installed on the table 12, and the cleaning component 4 is disposed 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 provided on one side wall of the protective cover 10. When the synchronous belt module 2 drives the rotating clamping component 7 to translate, causing the workpiece 7 to move, the U-shaped opening 10a is used to avoid interference with the workpiece 7.

[0034] Combination Figure 4 As shown, a plasma fan 40 is provided on the lower surface of the top plate of the protective cover 10, and the plasma fan 40 is spaced apart and directly above the brush 440. The purpose of providing the plasma fan 40 is to reduce the static electricity generated by the friction between the brush 440 and the workpiece 7.

[0035] Combination Figures 4 to 6 As shown, the cleaning assembly 4 also includes a vertical support plate 442 and a brush holder 44; the lower end of the vertical support plate 442 is fixedly installed on the table surface 12; the brush holder 44 is installed on the upper part of the vertical support plate 442; the center of the brush 440 is set as a brush shaft 446; the brush 440 is rotatably installed on the brush holder 44 via the brush shaft 446; a stepper motor 445 is installed on the brush holder 44; a drive pulley 447 is installed on the output shaft of the stepper motor 445, and a driven pulley 443 is installed at one end of the brush shaft 446; the drive pulley 447 and the driven pulley 443 are together fitted with a transmission belt 444. The stepper motor 445 drives the brush 440 to rotate through the active pulley 447, the transmission belt 444 and the driven pulley 443. During cleaning, since both the brush 440 and the workpiece 7 are rotating at high speed, the brush 440 scrapes across the surface of the workpiece 7 at high speed, effectively improving the cleaning effect.

[0036] Combination Figure 6 As shown, a flange plate 442a is integrally formed at the bottom end of the vertical support plate 442, and two oblong holes 442b are formed on the flange plate 442a; the longitudinal direction of the oblong holes 442b is parallel to the axis of the brush shaft 446; the vertical support plate 442 is connected to the table 12 by screws through the flange plate 442a, and the screws pass through the oblong holes 442b. By using the oblong holes 442b and the screws to cooperate, the position of the support plate 442 can be finely adjusted, and after the position is adjusted to the correct position, it can be locked by the screws.

[0037] Combination Figure 4 and Figure 5As shown, the cleaning assembly 4 also includes a pole 43a, a support frame 43, and a cleaning fluid spray box 42. The pole 43a is mounted on the table 12, and the support frame 43 is mounted on top of the pole 43a. The cleaning fluid spray box 42 is mounted on the support frame 43 and is located above the brush 440. The cleaning fluid spray box 42 has a hollow interior for holding the cleaning fluid. A leakage hole is provided at the bottom of the cleaning fluid spray box 42, and a non-woven fabric 441 is installed at the leakage hole. The brush 440 is in contact with the non-woven fabric 441. When cleaning the workpiece 7, the cleaning fluid spray box 42 contains the cleaning fluid, which passes through the leakage hole to the non-woven fabric 441. The non-woven fabric 441 is in close contact with the brush 440, and the brush 440 absorbs the cleaning fluid in this way, ensuring that the cleaning fluid is uniform and controllable. During operation, the cleaning effect is further improved because the brush 440 is dipped in cleaning solution to clean the workpiece 7.

[0038] In this embodiment, the cleaning equipment also includes a cleaning fluid storage tank (not shown in the figure); a pipe connector 40 is provided on the top of the cleaning fluid spray box 42; a peristaltic pump 45 is provided on the platform 12; the peristaltic pump 45 and the pipe connector 40 are connected by a pipe (not shown), and an inlet pipe (not shown) is provided on the peristaltic pump 45, with the inlet end of the inlet pipe connected to the cleaning fluid storage tank. The cleaning fluid in the cleaning fluid storage tank is drawn into the cleaning fluid spray box 42 by the peristaltic pump 45. In this embodiment, the cleaning fluid storage tank can be placed in the lower cavity 1a of the cabinet.

[0039] Combination Figure 2 and Figure 5 As shown, a dust suction port 51 is provided on the tabletop 12, and the dust suction port 51 is located directly below the brush 440; a vacuum cleaner 50 is provided in the lower cavity 1a of the cabinet, and the dust suction port 51 and the vacuum cleaner 50 are connected by a suction pipe. In this embodiment, when the brush 440 rotates and cleans the excess material from the workpiece 7, the dust falling off is sucked into the vacuum cleaner 50 through the dust suction port 51 by activating the vacuum cleaner 50.

[0040] Combination Figure 3As shown, the rotary clamping assembly 3 includes a base 300, a pneumatic rotary chuck 301, and a geared motor 302. The base 300 is mounted on the slider 203 of the synchronous belt module 2. The pneumatic rotary chuck 301 is rotatably mounted on the base 300. A U-shaped support plate 303 is mounted on the base 300, and the geared motor 302 is mounted on the U-shaped support plate 303. The geared motor 302 and the pneumatic rotary chuck 301 are connected by a first coupling 304. A cable chain 305 is provided on the table 12, and the cable chain 305 is arranged parallel to one side of the synchronous belt module 2. The cable chain 305 is used to accommodate the cable of the geared motor 302.

[0041] Combination Figure 2 As shown, the pneumatic rotary chuck 301 is equipped with multiple spring collets of different diameters. A chuck placement frame 11 is provided on the table 12, and multiple through holes 11a of different diameters are arrayed on the chuck placement frame 11. The through holes 11a are used to place the spring collets of the pneumatic rotary chuck 301. The pneumatic rotary chuck 301 can meet the requirements of changing models by assembling spring collets of different diameters, that is, by changing different spring collets, workpieces 7 of different specifications and models can be clamped.

[0042] Combination Figure 1 As shown, a controller 6 is installed in the upper cavity 1b of the cabinet. The controller 6 is connected to the stepper motor 445, the peristaltic pump 45, the translation stepper motor 200 of the synchronous belt module 2, and the reduction motor 302 in the rotary clamping assembly 3.
