The existing valve grinding method is manual grinding after repair welding or turning and grinding by machine tools. If the gate of a large gate valve such as DN500 is manually ground, due to the gate weight of several hundred kilograms, four people are required to work in turns. It is a repetitive mechanical labor. The grinding process is very time-consuming and labor-intensive, and the efficiency is very low, wasting manpower and material resources. If lathe turning and grinding is used, small-diameter valves can still be used. For the gate of large-diameter valves, due to the excessive weight and difficulty in transportation, the work intensity of workers increases again. Utility Model Content

[0019] like Figure 1-2As shown, the utility model provides a gate valve gate grinding device, including a grinding disc 10 connected to a motor 1 and a reducer 2, wherein the reducer 2 is fixedly connected to a reducer base 3, the reducer base 3 is vertically arranged, and the reducer base 3 is threadedly connected to a handwheel screw 5, and the reducer base 3 can be driven to move up and down by rotating the handwheel screw 5. The reducer base 3 is connected to a reducer guide sleeve 4, and the reducer guide sleeve 4 is sleeved on a column 6. Specifically, the column 6 is a double column structure, and the top of the double column is fixedly connected to a top plate 7. The double column structure can more stably support the power assembly and the grinding disc, and provide a stable foundation for the grinding process.
[0020] like Figure 3-4 As shown, the reducer output end 2-1 of the reducer 2 is a spherical structure, on which a boss protruding out of the sphere is provided. Specifically, a pin shaft 2-2 is provided through the middle of the spherical structure of the reducer output end 2-1, and both ends of the pin shaft 2-2 extend out of the spherical structure to form a boss. In this way, the grinding disc 10 can be rotated along the spherical surface within a certain range, and the boss can drive the grinding disc 10 to rotate. The grinding disc 10 is connected to the reducer output end 2-1 through a grinding disc connector 11, and the grinding disc connector 11 is provided with a movable groove 11-3 for accommodating the spherical structure and the boss of the reducer output end 2-1, and a movable space is provided between the movable groove 11-3 and the spherical structure and the boss of the reducer output end 2-1. Specifically, the grinding disc connector 11 includes a connector body 11-1, a cover plate 11-2, and a movable groove 11-3. The movable groove 11-3 is provided with a movable groove 11-3 that matches the spherical structure and the boss of the reducer output end 2-1. The top of the connector body 11-1 is fixedly connected to the cover plate 11-2. The middle part of the cover plate 11-2 is opened for the reducer output end 2-1 to pass through. After the connector body 11-1 and the movable groove 11-3 are assembled, the interior of the grinding disc connector 11 provides a movable space for the reducer output end 2-1, so that the grinding disc 10 can move within a certain range and better fit with the gate surface to be ground. The grinding disc 10 can also be driven to rotate by relying on the boss.
[0021] The bottom of the column 6 is connected and fixedly connected to the base 8. Figure 5 As shown, the base 8 is provided with a plurality of slideways 8-1, and the slideways 8-1 are provided with adjustment limiters 9 for limiting the gate plate. Specifically, four slideways 8-1 can be provided, of which two slideways 8-1 are arranged horizontally and the other two are arranged vertically, so that the adjustment limiters 9 limit the gate plate to be ground from four equally divided points on the circumference.

The first screw 9-3 is loosened to move the adjustment limiter 9 on the slide 8-1. After the position is fixed, the first screw 9-3 is tightened to fix the adjustment limiter 9, and then the second screw 9-5 is adjusted to make the end of the second screw 9-5 press against the side of the gate plate to be ground to complete the fixing of the gate plate. Then the upper and lower positions of the grinding disc 10 are adjusted by the hand wheel screw 5 so that the grinding disc 10 fits the surface of the gate plate, and the motor 1 and the reducer 2 are started to grind the grinding disc 10. After grinding, the motor 1 and the reducer 2 are stopped, and the grinding disc 10 is adjusted upward by the hand wheel screw 5 to separate the grinding disc 10 from the gate plate, and the adjustment limiter 9 is adjusted to remove the gate plate.
