Description

Technical Field

[0001] This utility model relates to the field of rotor processing technology, specifically to a processing device for motor rotors. Background Technology

[0002] The motor rotor is the core rotating component of the motor, working in conjunction with the stator to achieve the mutual conversion of electrical energy and mechanical energy.

[0003] In the field of motor rotor processing, traditional rotor grinding equipment often suffers from several problems: First, the power transmission structure is complex, and frequent failures are likely due to the large number of components and complicated connections. This not only increases maintenance costs but may also affect polishing accuracy due to power fluctuations, making it difficult to guarantee the surface processing quality of the rotor. Second, the rotor clamping mechanism lacks flexibility and cannot make the rotor move after clamping, resulting in a single polishing direction. Third, the spacing of the polishing components is inconvenient to adjust, making it difficult to adapt to the processing needs of rotors of different specifications. Moreover, the debris generated during the polishing process is prone to splashing, posing safety hazards and polluting the workshop environment. At the same time, the debris is difficult to clean, further reducing processing efficiency and equipment lifespan. These problems all restrict the overall effect and economy of motor rotor processing.

[0022] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0023] A preferred embodiment of the motor rotor processing device provided by this utility model is, for example... Figures 1 to 6 As shown: A machining device for motor rotors, comprising: Operating platform 1 is the main support structure for machining the motor rotor; Drive unit 2, mounted on the top surface of operating table 1, is used to drive polishing assembly 3 to polish the motor rotor. Polishing assembly 3 is mounted above operating table 1. The drive unit 2 consists of a motor, a drive wheel, a driven wheel, and a belt. The output end of the motor is fixedly installed with the drive wheel, and the drive wheel and the driven wheel are rotatably connected by a belt. The motor is fixedly installed with the top surface of the operating table 1 through a motor mount. Among them, the polishing component 3 is provided with a protective cover 4 fixedly installed on the top surface of the operating table 1. The two sides of the protective cover 4 have rectangular openings, and the front of the protective cover 4 is hollowed out. Clamping assembly 5 is used to clamp the motor rotor, which facilitates stable processing of the motor rotor. The clamping assembly 5 is arranged parallel to the polishing assembly 3 above the polishing assembly 3, and the clamping assembly 5 is connected to the protective cover 4. The sliding component 7 is positioned below the clamping component 5, perpendicular to the polishing component 3, and is connected to the polishing component 3.

[0024] When in use, the motor rotor that needs to be polished is placed on the polishing assembly 3, and then the clamping assembly 5 is used to clamp the column, and then the drive unit 2 drives the polishing assembly 3 to polish it.

[0025] Based on the above implementation scheme, polishing component 3 includes: Polishing rollers 31, two are provided in pairs; Mounting shaft 32, two are arranged in pairs. The outer wall of the mounting shaft 32 is fixedly installed with the inner wall of the polishing roller 31. Support frames 33 are rotatably provided at both ends of the mounting shaft 32 through bearings. The end of the mounting shaft 32 is connected to the drive unit 2. One of the mounting shafts 32 is not connected to the drive unit 2 at one end.

[0026] In this embodiment, a base plate 34 is fixedly installed on the bottom surface of the support frame 33. The bottom surface of one base plate 34 is fixedly installed to the top surface of the operating table 1 through the first support seat 35, and the bottom surface of the other base plate 34 is connected to the top surface of the operating table 1 through the sliding component 7.

[0027] In the specific implementation process, the pair of polishing rollers 31 are connected to the support frame 33 through the mounting shaft 32, and only one mounting shaft 32 is connected to the drive unit 2. This structure allows the two polishing rollers 31 to form a synergistic polishing effect, improve the polishing efficiency of the motor rotor surface, and the single-sided drive design can simplify the transmission structure, reduce the probability of equipment failure, and reduce maintenance costs.

[0028] Furthermore, the centerlines of the two mounting shafts 32 are on the same horizontal plane as the centerline of the rectangular opening on the side of the cover 4, and the outer diameter of the mounting shaft 32 is smaller than the height of the inner wall of the rectangular opening.

[0029] Here, the protective cover 4 can block the flying debris generated during the grinding process, ensuring the safety of operators and reducing dust pollution in the workshop.

[0030] Based on the above implementation scheme, the clamping component 5 includes: The first cylinder 51 is located on the right side of the cover 4. The piston rod of the first cylinder 51 passes through the right side of the cover 4 and extends to be fixedly installed with the first retainer 52 located inside the cover 4. The second cover 53 is arranged opposite to the first cover 52 and is on the same horizontal plane. The end of the second cover 53 is fixedly installed to the inner side of the cover 4. The second cover 53 has an elastic part inside.

[0031] In the specific implementation process, the first cylinder 51 can drive the first clamping cover 52 to push the other end of the motor rotor placed between the two polishing rollers 31 into the second clamping cover 53, thereby achieving stable clamping of the motor rotor and making it stable for polishing.

[0032] In this embodiment, a mounting plate 6 is fixedly installed at the end of the first cylinder 51. The lower end of the mounting plate 6 is fixedly installed to the top surface of the operating table 1 by bolts. The first cylinder 51 can be securely installed by the mounting plate 6.

The reciprocating spring 56 is fixedly installed at one end to the end face of the T-shaped slider 55, and at the other end to the inner side wall of the second cover 53.

[0034] Here, the end of the electronic rotor makes slight contact with the end face of the T-shaped slider 55 without compressing the reciprocating spring 56. This allows the motor rotor to move slightly back and forth under the polishing of the two polishing rollers 31, thereby increasing the polishing force and polishing efficiency.

[0035] Based on the above implementation scheme, the sliding component 7 includes: The guide rail 73 is located below another base plate 34, and the bottom surface of the guide rail 73 is fixedly installed to the top surface of the operating table 1 through the second support 75.

[0036] The second cylinder 71 is fixedly installed to another base plate 34 via a connecting block 72.

[0037] In specific implementation, with the cooperation of slider 74 and guide rail 73, the second cylinder 71 can drive another support frame 33 to move the polishing roller 31 which is not connected to the drive unit 2, and can conveniently clean debris between the two polishing rollers 31.

[0038] In this embodiment, a fixing seat 8 is fixedly installed on the lower surface of the second cylinder 71. The fixing seat 8 is fixedly installed to the top surface of the operating table 1 by bolts. The second cylinder 71 can be stably installed by the installed fixing seat 8.
