Description

Technical Field

[0001] The utility model relates to the technical field of spool processing, in particular to an automatic spool grinding and polishing device. Background Technique

[0002] Spool devices are very common in the stop valves or overflow valves of valve structures, or appear in the discharge of thinner products. The spool is prone to wear under high pressure, especially inside the spool. Therefore, the grinding work on the inside and outside of the spool is very frequent.

[0003] In the prior art, the grinding part is too limited and can only take care of the polishing work in some areas. Especially for the inside of the spool, it is difficult to completely remove burrs in one go, which has a great impact on the post-production use and subsequent maintenance.

[0004] In order to overcome the above difficulties, the prior art (Chinese patent with application number: CN117415688B, application date: November 30, 2023) discloses a spool grinding device, which relates to the technical field of spool grinding, including a mounting base and a mounting bracket. The mounting bracket is installed at the left edge of the upper end surface of the mounting base. A connecting slide rail is provided inside the mounting bracket. A threaded rod is installed inside the connecting slide rail. An adjusting bracket is installed on the outer surface of the threaded rod. A connecting slide rod is arranged on the right side of the threaded rod inside the adjusting bracket. A support shaft is arranged on the right side of the upper end surface of the mounting base. A support plate is installed at the upper end of the support shaft. By setting an extrusion mechanism assembly and a cleaning mechanism, the connecting gear is rotated, so that the transmission gear rotates in the opposite direction to the connecting block, and the extrusion block is closely attached to the extrusion groove to perform the extrusion function, so that the spool body fixed on the support plate rotates in the opposite direction to the grinding mechanism through the support shaft, further improving the grinding effect.

[0005] Although the prior art can perform spool polishing work in a larger range comprehensively, there is no corresponding measure to deal with the dust hazard during the grinding process. If water is not used to moisten the grinding material, a lot of dust will be generated and the material will become rough, increasing the friction, resulting in a non-smooth grinding of the spool.
