DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objectives, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0029] In the following description, a large number of specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the concept of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0030] Secondly, "one embodiment" or "embodiment" referred to herein means that a specific feature, structure or characteristic can be included in at least one implementation of the present application. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an embodiment that is separate or alternative to other embodiments.

The polishing device applied to magnetic ring processing includes a radial polishing assembly 8, an axial clamping assembly 9 and a hydraulic synchronous assembly 10. The axial clamping assembly 9 and the radial polishing assembly 8 are synchronously actuated by coordinated control of the hydraulic synchronous assembly 10 to clamp and position the magnetic ring. Subsequently, the main shaft 2 and each driving motor are started to rotate the first polishing drill bit 83 and the second polishing drill bit 95 respectively, so that the first polishing drill bit 83 rotates around its own axis during revolution, and the magnetic ring also rotates during the process, achieving the purpose of polishing the magnetic ring.

[0032] Specifically, the base table 1 is fixedly arranged on the ground, and a control motor for driving the main shaft 2 to rotate is arranged in the base table 1; the main shaft 2 is arranged at the center of the base table 1 and serves as a transmission shaft; a guide sleeve 3 is arranged on the outer circumferential side of the main shaft 2; and a support sleeve 4 is rotatably arranged on the outer circumferential side of the guide sleeve 3. The guide sleeve 3 and the support sleeve 4 form a multi-layer sleeve structure that can rotate relative to each other, not only achieving axial positioning and radial support, but also transmitting rotary motion under the driving of the main shaft 2, which helps to improve the rigidity and motion accuracy of the overall structure.

[0033] The sleeve disc 5 is rotatably arranged at the top end of the main shaft 2 through the planetary gear set 6, and a radial support groove 7 is formed in the circumferential side of the sleeve disc 5. The sleeve disc 5 is connected with the main shaft 2 through the planetary gear set 6, and can convert the rotary motion of the main shaft 2 into the rotation of the sleeve disc 5, so as to drive the radial polishing assembly 8 mounted thereon to rotate.

The sliding block 81 can move radially along the support groove 7, so as to drive the first polishing drill bit 83 to approach or move away from the inner wall of the magnetic ring. The sealing design of the sliding cavity 82 at both ends forms a closed hydraulic chamber inside, which is convenient for controlling the two first polishing drill bits 83 to open towards each other or close away from each other through hydraulic pressure, so as to adapt to magnetic rings with different inner diameters.

The clamping hydraulic table 91 drives the linear frame 92 to move axially, so that the two clamping pieces 93 approach from both sides and clamp the end face of the magnetic ring. At this time, the second polishing drill bit 95 arranged in the clamping piece 93 can abut against the end edge of the magnetic ring through the grinding surface, realizing the combination of clamping positioning and end face polishing function, effectively reducing the process conversion, and the driving piece 96 is built in the linear frame 92, which can directly provide rotary power for the second polishing drill bit 95.
