Only its use is carried out without modification, so the control method and circuit connection will not be described in detail.

[0038] Working principle:

[0039] When actually using the turning and grinding fixture for the outer circle of the valve disc, the operator first selects two groups of rod bars 22 with appropriate sizes, and then inserts the two groups of connecting screws 21 at the ends of these two groups of rod bars 22 clockwise into the inner parts of the two groups of threaded blind holes 20 on the same side. Then, the operator rotates a handwheel by hand. This handwheel can drive a bidirectional lead screw 16 to rotate. Since a bidirectional lead screw 16 on the same side is in threaded engagement with two lead screw sleeves 17 on the same side, the rotating bidirectional lead screw 16 on the same side can push the two lead screw sleeves 17 on the same side to approach or move away from each other. The two lead screw sleeves 17 on the same side can drive the two rod bars 22 on the same side to move through the two moving plates 18 on the same side. When the gap length between the two rod bars 22 on the same side reaches an appropriate value, the valve disc can be sleeved on the side walls of the two rod bars 22 on the same side, and the two support hole plates 23 on the same side can support the valve disc. After multiple valve discs are sleeved, using the control panel, extend a second electric telescopic rod 26 on the same side, so that a pressing plate 27 on the same side can move downward. When multiple balls 29 on the same side contact the uppermost valve disc, synchronously install the valve discs of the remaining sizes. After the valve discs of multiple sizes are installed, using the control panel, make the drive motor 4 work. The output end of the drive motor 4 can drive the main gear 6 to rotate through the mounting shaft 5. Since the main gear 6 is in meshing engagement with multiple driven gears 3, the rotating main gear 6 can push the multiple driven gears 3 to rotate. The rotating multiple driven gears 3 can drive multiple concave seats 7 and valve discs of multiple sizes to rotate through multiple connecting shafts 2. During this process, the valve discs of multiple sizes during rotation can be turned and ground. Through the provided connecting shafts 2, concave seats 7 and rod bars 22, the valve discs of multiple sizes can be clamped simultaneously, improving the practicality of the turning and grinding fixture for the outer circle of the valve disc. At the same time, according to the above operations, it can be known that the output end of the drive motor 4 can drive the mounting shaft 5 to rotate, and the mounting shaft 5 can drive the shaft tube 12 to rotate through the cross plate 33 and the cross groove 34. At this time, the first socket plate 13 and the second socket plate 14 can drive multiple upper brush plates 15 and multiple lower brush plates 15 to rotate. At this time, the valve disc can be moved between the first socket plate 13 and the second socket plate 14. During the rotation of the multiple upper brush plates 15 and the multiple lower brush plates 15, the valve disc can be wiped and cleaned. Using the control panel, extend the first electric telescopic rod 10 to adjust the gap length between the first socket plate 13 and the second socket plate 14. Using the threaded engagement between multiple mounting screws 31 on the same side and multiple mounting nuts 32 on the same side, the operator can remove the multiple mounting nuts 32 on the same side counterclockwise by hand to detach the multiple brush plates 15 on the same side. Through the provided first socket plate 13, second socket plate 14 and brush plates 15, a cleaning structure is provided, which can clean the impurities on the surface of the valve disc in advance, providing protection for the clamping of the valve disc by the turning and grinding fixture for the outer circle of the valve disc.
