Description

Technical Field

[0001] The utility model relates to the technical field of valve processing, in particular to a valve grinding device. Background Art

[0002] Generally, there will be burrs on the surface of valve flange after processing, so it is necessary to polish the surface of the flange to remove the burrs after processing. The traditional polishing method is that workers use polishing tools to polish manually, which not only has low polishing efficiency but also low quality.

[0003] The existing valve flange grinding is mostly done by grinding one side first and then the other side. This is not only time-consuming and labor-intensive, but also requires staff to grind the other side. Moreover, if the grinding is not fine enough, there will be residual burrs on the surface of the flange valve, which seriously affects the product quality. Therefore, we have designed a valve flange grinding device to solve the above problems. Utility Model Content

[0004] In view of the above problems existing in the existing valve polishing device, the present utility model is proposed.

[0005] Therefore, the utility model aims to provide a valve grinding device to solve the problem of insufficient grinding precision.

[0012] Preferably, the gear ratio between the large gear and the small gear is 6:1.

[0013] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0014] 1. The utility model adopts a small gear to drive a large gear to rotate and grind the valve more finely. In order to grind the surface of the flange valve more finely, two gears are used. Because the rotation speeds of the two gears are different, the I-shaped grinding wheel rotates 360° and the valve rotates 60°, so the valve is fully polished. The rotation speed is controlled by the control panel, which is very convenient and quick.

Over a long period of time, the debris is collected and reused, thereby avoiding the waste of metal resources, preventing the debris from affecting the working environment, and saving the staff's cleaning time.

[0016] 3. The utility model adopts a protective cover to block the grinding debris to prevent the debris from being breathed into the body by the staff and causing harm to the staff. In order not to affect the normal grinding work, recesses are provided on both side walls of the protective cover. When falling, the effect of the recesses will not affect the rotation of the first rotating shaft, the second rotating shaft and the third rotating shaft. BRIEF DESCRIPTION OF THE DRAWINGS
