[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example:

[0026] See also Figure 1-Figure 2 The utility model provides a ball valve grinding processing device, including a motor 1, a pushing cylinder 2 is fixedly installed on the end of the rotating shaft of the motor 1, a connecting plate 3 is fixedly installed on the end of the inner rod of the pushing cylinder 2, and a first clamping cylinder 4 and a second clamping cylinder 5 are fixedly installed on the connecting plate 3 by bolts. The first clamping cylinder 4 and the second clamping cylinder 5 are arranged in opposite directions and an arc plate 6 is fixedly installed on the end of the inner rod of the first clamping cylinder 4 and the second clamping cylinder 5.

[0027] Specifically, such as Figure 1 As shown, the connecting plate 3 is L-shaped, the vertical body of the connecting plate 3 is provided with side through-holes, and the horizontal body of the connecting plate 3 is provided with upper through-holes, which facilitate the installation and fixation of the first pressing cylinder 4 and the second pressing cylinder 5.

[0028] Specifically, such as Figure 1As shown, threaded holes are provided at intervals on the first pressing cylinder 4 and the second pressing cylinder 5 , so that the overall length of the first pressing cylinder 4 and the second pressing cylinder 5 can be adjusted, allowing the arc plate 6 to pass through a smaller ball valve opening.

[0029] Specifically, the arc plate 6 is arranged to fit the arc shape of the inner wall of the cavity of the ball valve. The shape of the arc plate 6 matches the arc shape of the inner wall of the ball valve, so the ball valve will be automatically calibrated when stretched and pushed.

[0030] Working principle:

[0031] The first clamping cylinder 4 and the second clamping cylinder 5 are in a retracted state, and the pushing cylinder 2 is extended, extending the first clamping cylinder 4, the second clamping cylinder 5 and the arc plate 6 into the inner cavity of the ball valve, and then the first clamping cylinder 4 and the second clamping cylinder 5 are extended, and the arc plate 6 moves outward. Since the shape of the arc plate 6 fits the arc shape of the inner wall of the ball valve, the ball valve will be automatically calibrated when it is extended and pushed. After the arc plate 6 presses and fixes the ball valve, the motor 1 rotates, driving the ball valve to rotate and contact the grinder. Since there is enough space between the pushing cylinder 2 and the ball valve opening, the grinding device can grind more completely.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
