[0031] For examples, please refer to Figure 1-5 This utility model provides a technical solution:

[0032] A ball grinding device for a sliding ball valve includes a grinding table 1 and a ball 2. A rotary motor 3 is installed on the inner side of the grinding table 1. A mounting frame 4 and a bearing plate 5 are fixedly installed on the top of the grinding table 1. A grinding oil tank 6 and a hydraulic rod 7 are fixedly installed on the top of the mounting frame 4. An oil pump 601 is installed on the top of the grinding oil tank 6. A support column 701 is installed at the bottom end of the hydraulic rod 7. An annular tube 401 is installed at the bottom of the mounting frame 4. An oil outlet 402 is installed at the bottom of the annular tube 401. A fixing rod 501 is rotatably installed on the top of the bearing plate 5 through a bearing. An installation hole 201 is opened on the bottom surface of the ball 2. A grinding sleeve 202 is installed on the outer side of the ball 2. An adjustment mechanism 8 is provided between the grinding sleeve 202 and the grinding table 1.

[0033] Specifically, the outer top surface of the fixing rod 501 is in contact with the inner wall of the mounting hole 201, the telescopic end of the hydraulic rod 7 passes through the top surface of the mounting bracket 4 and extends to its inner side, the support column 701 is located directly above the fixing rod 501, and its bottom is tapered, and the output end of the rotary motor 3 passes through the inner surface of the grinding table 1 and is fixedly connected to the bottom end of the fixing rod 501.

[0034] In this embodiment, the fixing rod 501 is mainly used to make contact with the mounting hole 201 at the bottom of the ball 2, while the hydraulic rod 7 is mainly used to drive the support column 701 downward so that the support column 701 contacts the top of the ball 2, which helps to stabilize the ball 2. At the same time, the rotary motor 3 is mainly used to drive the fixing rod 501, thereby ensuring the stable rotation of the ball 2 during the grinding process.

[0035] Specifically, the input end of the oil pump 601 is connected to the inside of the grinding oil tank 6 through a pipe, and its output end extends inward through the outer side of the annular pipe 401 through a hose. The top of the annular pipe 401 is fixedly connected to the surface of the mounting bracket 4 through a connecting rod. The oil outlet 402 is distributed in an annular shape at equal intervals about the bottom surface of the annular pipe 401.

[0036] In this embodiment, the oil pump 601 is mainly used to guide the grinding oil in the grinding oil tank 6, so that it is delivered to the annular pipe 401 and evenly sprayed onto the grinding surface of the ball 2 through the annularly distributed oil outlets 402, thus ensuring efficient lubrication during the grinding process.

[0037] In this embodiment, please refer to Figure 1 and Figure 5 The adjustment mechanism 8 includes a mounting base 801 and a fastening post 802. An adjustment motor 803 is fixedly installed on the left side of the mounting base 801. A square groove 804 is opened on the rear surface of the mounting base 801. An adjustment screw 805 and a limiting rod 806 are respectively arranged inside the square groove 804. A movable support plate 807 is sleeved on the outer side of both the adjustment screw 805 and the limiting rod 806. A fastening hole 808 is opened on the outer surface of the movable support plate 807. The fastening post 802 is fixedly installed on the opposite side surface of the grinding sleeve 202.

[0038] Specifically, the output end of the adjusting motor 803 passes through the left side surface of the mounting base 801 and is fixed to the left end of the adjusting screw 805. The outer surface of the adjusting screw 805 is threadedly connected to the inner wall of the movable support plate 807. The outer surface of the limiting rod 806 slides against the inner wall of the movable support plate 807. The threads at the left and right ends of the outer side of the adjusting screw 805 are in opposite directions. The movable support plate 807 is mirrored about the outer central axis of the adjusting screw 805. The inner wall of the fastening hole 808 is tightly fitted to the outer surface of the fastening post 802.

[0039] In this embodiment, the adjustment motor 803 is mainly used to drive the adjustment screw 805. Under the threaded transmission between the adjustment screw 805 and the movable support plate 807, and the sliding cooperation between the limit rod 806 and the movable support plate 807, the movement of the movable support plate 807 can be precisely controlled. This allows the movable support plate 807 to drive the grinding sleeves 202 to move smoothly in opposite directions, ensuring that the contact pressure and position between the ball 2 and the grinding sleeve 202 can be precisely controlled during the grinding process, thus improving the accuracy and efficiency of the grinding.

[0040] The working process of this utility model is as follows: When using a ball grinding device for a sliding ball valve, the ball 2 is first moved so that the mounting hole 201 contacts the fixed rod 501. Then, the hydraulic rod 7 drives the support column 701 so that the bottom of the support column 701 contacts the top of the ball 2, thereby ensuring the stability of the ball 2. Then, the position of the grinding sleeve 202 can be adjusted by starting the adjusting motor 803. The adjusting motor 803 drives the adjusting screw 805 to rotate. Simultaneously, the moving support plate 807 can move synchronously in the opposite direction when the adjusting screw 805 rotates, and the moving support plate 807 and the limiting rod 806 move in opposite directions. The smooth sliding motion causes the grinding sleeve 202 to gradually approach the ball 2, ensuring synchronous adjustment on both sides of the grinding sleeve 202 and facilitating subsequent uniform grinding. At this time, the rotary motor 3 is started, and the output end of the rotary motor 3 drives the fixed rod 501 to rotate, ensuring the stable rotation of the ball 2 during the grinding process. During the grinding process, the grinding oil in the grinding oil tank 6 is transported by the oil pump 601 to the annular pipe 401, and then evenly sprayed onto the ball 2 through the oil outlet 402, ensuring efficient lubrication during the grinding process, improving grinding efficiency and the surface finish of the ball 2, and meeting the needs of the user.

[0041] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
