Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, and in particular to a polishing device for the surface of a retainer housing. Background Technology

[0002] The bearing cage housing is a crucial component of a bearing, its main functions including separating the rolling elements, maintaining their proper trajectory, and reducing friction. Cage housings are typically made of metallic or non-metallic materials, including stamped steel cages, polyamide cages, and brass cages. The primary method for deburring bearing brass cages is through magnetic polishing machines, utilizing magnetic force for polishing and deburring. This method is suitable for various metal parts, especially those with complex shapes. It is highly efficient and has minimal impact on the dimensional accuracy of the workpiece.

[0003] In existing retainer housing surface polishing devices, the polishing cylinder is usually placed directly on the host machine without a reasonable limiting structure. When the retainer housing inside the polishing cylinder is concentrated on one side or one end, the polishing cylinder is subjected to uneven force, causing it to shift and shake. Moreover, the rotating disk installation structure is relatively complicated, and it is not easy to repair or replace it in time when the magnetic block is worn or shifted. Utility Model Content

[0035] The polishing machine body 1 has a control panel 101 on the top rear side and a protective frame 102 on the top front side. The protective frame 102 is a rectangular frame structure and has a pad 103 inside. The pad 103 is located between the polishing cylinder 3 and the fixed seat 4.

[0036] In this embodiment of the disclosure, such as Figure 2 and Figure 3 As shown, the bottom of the limiting frame 2 is provided with two support columns 201, and the two support columns 201 are distributed in a vertical parallel manner. The limiting frame 2 has two rectangular slots 202, and the two rectangular slots 202 are distributed symmetrically. The limiting frame 2 has two through holes 203, and the rectangular slots 202 are located between the two through holes 203.

[0037] Two support blocks 301 are provided on both sides of the outer peripheral surface of the polishing cylinder 3. Two elastic buckles 302 are provided at the bottom of the support block 301, and the two elastic buckles 302 are distributed symmetrically. Two limiting round rods 303 are provided at the bottom of the support block 301, and the elastic buckles 302 are located between the two limiting round rods 303. A compression spring 304 is fitted on the limiting round rod 303.

[0038] The support block 301 corresponds to the position of the limiting frame 2, and the elastic buckle 302 engages with the rectangular slot 202 of the limiting frame 2. The limiting rod 303 slides into the through hole 203, and the compression spring 304 supports the support block 301 and the limiting frame 2. In this utility model, there are two limiting frames 2. The elastic buckle 302 engages with the rectangular slot 202 of the limiting frame 2. By utilizing the elasticity of the compression spring 304 mounted on the limiting rod 303, the polishing cylinder 3 can be installed more stably, effectively preventing it from shifting or shaking.

[0039] Example 2, based on Example 1, such as Figure 5 and Figure 6 As shown, the base 4 has a base frame 401 at the bottom, and the servo motor 6 is fixedly installed at the bottom of the base frame 401. The base 4 has a rectangular frame structure, and a support frame 402 is fixedly installed inside the base 4. The rotating disk 5 is located above the support frame 402.

[0040] The top of the rotating disk 5 is provided with a magnetic block 501, and the magnetic blocks 501 are distributed in a ring array.

Through the cooperation of the ratchet sleeve 602 and the ratchet pawl 503, the first rotating shaft 502 can drive the rotating disk 5 to rotate. Using the magnetic attraction of the magnetic block 501, the magnetic needle in the polishing cylinder 3 rotates at high speed to polish the retainer shell. Because of the ratchet sleeve 602 and the ratchet pawl 503, the rotating disk 5 can be quickly disassembled and installed, and it is convenient to repair or replace the magnetic block 501 of the rotating disk 5 in a timely manner if it is worn or misaligned.

[0042] The working principle of this embodiment is as follows: When polishing the outer shell of the retainer inside the polishing cylinder 3, the elastic buckle 302 engages with the rectangular slot 202 of the limiting frame 2, and the elasticity of the compression spring 304 mounted on the limiting rod 303 makes the installation of the polishing cylinder 3 more stable, effectively preventing it from shifting or shaking; the servo motor 6 provides power to drive the second rotating shaft 601 to rotate, and the ratchet sleeve 602 and ratchet pawl 503 cooperate with each other to make the first rotating shaft 502 drive the rotating disk 5 to rotate. The magnetic attraction of the magnetic block 501 causes the magnetic needle inside the polishing cylinder 3 to rotate at high speed to polish the outer shell of the retainer. Because of the ratchet sleeve 602 and ratchet pawl 503, the rotating disk 5 can be quickly disassembled and installed, and it is convenient to repair or replace the magnetic block 501 of the rotating disk 5 in a timely manner if it is worn or shifted.
