Description

Technical Field

[0001] This utility model relates to the field of motor processing technology, and more specifically to a motor rotor processing equipment. Background Technology

[0002] The outer surface of the motor rotor needs to be polished to make it smooth and aesthetically pleasing. Existing motor rotor polishing devices are complex in structure, inconvenient to operate, and difficult to clamp and fix the two ends of the motor rotor, thus affecting polishing efficiency, hindering all-round polishing, and resulting in low polishing precision.

[0003] A motor rotor grinding device, application number 201921705447.3, includes a base with vertical arms mounted at both ends of the upper side. A first rotor positioning seat and a second rotor positioning seat are respectively mounted on one side of the upper end of each vertical arm, and both seats have positioning holes. A first gear is mounted on one side of the first rotor positioning seat, and a third gear is meshed with a second gear on one side of the first gear. A strip-shaped hole is formed on one side of the vertical arm, and a first grinding roller and a second grinding roller are respectively mounted within the hole via a connecting shaft. A motor is driven to one side of the third gear. This motor rotor grinding device can position both ends of a motor rotor, and then the motor drives the rotor to rotate and rub against the first and second grinding rollers for grinding. It offers high grinding efficiency and precision. However, this device is not suitable for simultaneously grinding multiple rotors efficiently. Utility Model Content

Detailed Implementation

[0016] See Figures 1 to 4 The diagram shows an embodiment of the present invention in which multiple motor rotors are simultaneously ground.

[0017] A motor rotor processing device includes a frame 101, on which a motor I 104 is mounted. The output shaft of the motor I 104 is connected to a grinding roller 107 via a coupling. An annular disk 201 is mounted on the frame 101 and is slidably connected to the grinding roller 107. Multiple bushings 203 are evenly distributed on the annular disk 201 around the axis of the grinding roller 107. The lower ends of multiple rotors 108 are respectively inserted into the multiple bushings 203 and in contact with the surface of the grinding roller 107.

[0018] The lower ends of the rotor shafts on multiple rotors 108 are respectively inserted into multiple bushings 203. The surface of the rotor 108 inserted into the bushing 203 contacts the surface of the grinding roller 107. The grinding process of the surface of multiple rotors 108 can be achieved by controlling the motor I 104 to start and drive the grinding roller 107 to rotate.

[0019] During the grinding process, the grinding roller 107 does not need to move back and forth. It is only necessary to control the motor I 104 to start and drive the grinding roller 107 to rotate, so that multiple rotors 108 can be ground at the same time, thereby improving the grinding efficiency and grinding quality of the rotors 108.

[0020] Multiple bushings 203 are provided around the grinding roller 107, and each bushing 203 can be used to insert a rotor 108, thereby enabling multiple rotors 108 to be ground simultaneously, further improving work efficiency.

[0021] See Figure 4 The diagram shows an embodiment of grinding the circumferential surface of each rotor in accordance with the present invention.

[0022] Multiple motors II 202 are fixedly connected to the annular disk 201, and multiple bushings 203 are respectively connected to the output shafts of the multiple motors II 202 through couplings;

[0023] Each bushing 203 has a rubber layer bonded to its inner wall, which increases the friction between it and the rotor shaft. This allows the bushing 203 to transmit power to the corresponding rotor 108 through the rotor shaft when the motor II 202 starts and drives the bushing 203 to rotate. This causes the rotor 108 to rotate, and the entire circumference of the rotating rotor 108 can contact the grinding roller 107, thus achieving comprehensive grinding of the entire circumference of each rotor 108.

[0024] See Figure 3 The diagram shows an embodiment of improving the grinding quality of rotor 108 according to the present invention.

[0025] The motor I 104 is connected to the frame 101 with a clearance fit. The lower end of the motor I 104 is fixedly connected to the base 105 by screws. Two electric push rods II 106 are symmetrically fixed on the base 105. The telescopic ends of the two electric push rods II 106 are welded to the frame 101.

[0026] The telescopic ends of the two bases 105 extend and retract continuously, driving the motor I 104 to move up and down reciprocally. The motor I 104 drives the grinding roller 107 to move up and down reciprocally. During the grinding process, the grinding roller 107 moves up and down continuously in conjunction with itself, so that the grinding roller 107 can fully contact the multiple rotors 108, thereby improving the grinding quality of the rotors 108.

[0027] See Figure 5 A schematic diagram of an embodiment of limiting multiple self-rotating rotors 108 according to the present invention is shown.

[0028] A vertical rod 204 is welded to the annular disk 201, and a limiting ring 205 for limiting the rotor 108 is installed at the upper end of the vertical rod 204.

[0029] The limiting ring 205 can limit the rotation of multiple rotors 108, preventing the grinding roller 107 from moving vertically through friction and thus improving the stability of the rotors 108 within the bushing 203.

[0030] Furthermore, the limiting ring 205 has multiple insertion holes 206 corresponding to the bushing 203;

[0031] The shaft on the rotor 108 can be inserted into the corresponding socket 206, which can limit the rotor 108 without interfering with the rotation of the rotor 108.

[0032] See Figure 2 and 3 The diagram shows an embodiment of controlling the vertical reciprocating movement of multiple rotors 108 according to the present invention.

[0033] Two electric push rods I102 are symmetrically fixed on the frame 101, and the annular disk 201 is connected to the telescopic ends of the two electric push rods I102.

[0034] Two electric push rods I 102 continuously extend and retract, driving the annular disk 201 and its multiple rotors 108 to move vertically back and forth. It should be noted that the extension and retraction directions of the extension and retraction ends of the two electric push rods I 102 are opposite to those of the extension and retraction ends of the two electric push rods II 106. In this way, the rotors 108 move back and forth in opposite directions relative to the grinding roller 107 in the vertical direction, thereby further enhancing the grinding efficiency and grinding quality of the multiple rotors 108.

[0035] Furthermore, the telescopic ends of the two electric push rods I 102 are each welded with a mounting plate 103, and the two electric push rods I 102 are detachably connected to the annular disk 201 via the mounting plate 103 and screws, respectively.

[0036] The mounting disc 103 and the annular disc 201 are detachably connected, making it easy to remove the annular disc 201 and clean the dust inside when not grinding.

[0037] Furthermore, a retaining ring 207 is fixedly connected to the annular disk 201, which can assist in collecting dust that falls onto the annular disk 201 during the polishing process.

[0038] See Figure 5 A schematic diagram of an embodiment in which the limiting ring 205 is detachable according to the present invention is shown;

[0039] The limiting ring 205 and the vertical rod 204 are detachably connected by screws; this facilitates the removal of the limiting ring 205 for the installation and removal of multiple rotors 108.

[0040] It should be added that: the grinding roller 107 and the plurality of rotors 108 all rotate clockwise, so that each rotor 108 rotates in the opposite direction to the grinding roller 107, thereby improving the grinding effect on the surface of the rotor 108.

[0041] Both electric actuator I 102 and electric actuator II 106 have flanges welded to their lower ends. Both electric actuator I 102 and electric actuator II 106 are fixedly connected to the frame 101 and the base 105 by flanges and screws.

[0042] One option for the electric linear actuator I 102 and electric linear actuator II 106 is JS-TGZ-U2, and other applicable models in the prior art can also be used.

[0043] The model numbers for motor I 104 and motor II 202 are provided as Z2-11 to 112, and other applicable models in the prior art can also be used.
