DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 3 A ball valve ball core assembly tool comprises a mounting seat 1. In order to facilitate the limiting of the ball valve body 12, a limiting device is arranged on the inner side of the mounting seat 1. The limiting device comprises a hydraulic cylinder 2, an extrusion block 3, a starting switch 4, an adjusting motor 5, an adjusting rod 6 and a limiting rod 7. The hydraulic cylinder 2 controls the extrusion block 3 to move downward. The extrusion block 3 is subjected to a reaction force to squeeze the starting switch 4 to start the adjusting motor 5. The adjusting motor 5 starts to control the rotating shaft to drive the adjusting rod 6 to rotate. The adjusting rod 6 rotates to make the two limiting rods 7 move horizontally toward each other.

[0023] In order to facilitate the control of the fixed round block 21, the upper and lower ends of the mounting seat 1 are rotatably connected with a rotating disk 11, the hydraulic cylinder 2 is fixedly installed inside the lower end of the rotating disk 11 located above, and the fixed round block 21 is fixedly installed on the lower movable end surface of the hydraulic cylinder 2. The extrusion block 3 is slidably inserted into the lower end of the fixed round block 21. When the hydraulic cylinder 2 is started, the fixed round block 21 will be controlled to descend, so that the extrusion block 3 squeezes the ball valve body 12 to limit the position, and the rotation of the rotating disk 11 will drive the hydraulic cylinder 2 to rotate.

[0024] In order to ensure that the limit rod 7 remains horizontal and slides in the fixed circular block 21, the adjusting rod 6 is rotatably connected to the inside of the fixed circular block 21, and a limit circular plate 61 is fixedly installed on the outer surface of the adjusting rod 6. The limit circular plate 61 is rotatably connected to the inside of the fixed circular block 21. The two limit rods 7 are respectively slidably inserted in the left and right sides of the fixed circular block 21. The outer surfaces of the two limit rods 7 are fixedly installed with limit plates 71. The limit plates 71 are slidably inserted in the inside of the fixed circular block 21. The limit circular plate 61 is stuck in the fixed circular block 21 and rotates, ensuring that the adjusting rod 6 remains stable and rotates in the fixed circular block 21. The limit plate 71 ensures that the limit rod 7 remains horizontal and slides in the fixed circular block 21.

[0025] In order to facilitate the control of the rotation of the rotating rod 51 and the driving gear 52, the adjusting motor 5 is fixedly installed inside the fixed round block 21, the rotating shaft of the adjusting motor 5 is fixedly installed with the rotating rod 51, the outer surface of the rotating rod 51 is fixedly installed with the driving gear 52, the outer surface of the adjusting rod 6 is fixedly installed with the driven gear 62, the outer surface of the driving gear 52 is meshed with the outer surface of the driven gear 62, when the adjusting motor 5 is started, the rotating shaft drives the rotating rod 51 and the driving gear 52 to rotate, and the driving gear 52 drives the driven gear 62 to rotate.

[0026] In order to facilitate the extrusion block 3 to control the starting switch 4, the starting switch 4 is fixedly installed inside the fixed round block 21 and located above the extrusion block 3. The starting switch 4 is electrically connected to the adjusting motor 5 through a wire. A ball valve body 12 is placed in the middle of the mounting seat 1. The upper and lower surfaces of the ball valve body 12 are fixedly mounted with a mounting cylinder 13. The inner surface of the mounting cylinder 13 contacts the outer surface of the limit rod 7. When the extrusion block 3 moves downward to squeeze the mounting cylinder 13, it will move upward to squeeze the starting switch 4, and the starting switch 4 will control the adjusting motor 5 to start.

[0027] In order to facilitate the control of the two limit plates 16 to clamp the two sides of the ball valve body 12, a control motor 14 is fixedly installed on the upper surface of the mounting seat 1, and the rotating shaft of the control motor 14 is fixedly connected to the upper surface of the rotating disk 11. Electric telescopic rods 15 are fixedly installed on the left and right sides of the rotating disk 11 located above. The lower ends of the two electric telescopic rods 15 are fixedly installed with limit plates 16. The outer surface of the limit plate 16 is slidably connected to the outer surface of the ball valve body 12. When the control motor 14 is started, the rotating shaft drives the rotating disk 11 to rotate. When the electric telescopic rod 15 is started, it will extend to clamp the two limit plates 16 on both sides of the ball valve body 12, thereby driving the ball valve body 12 to rotate when the rotating disk 11 rotates.

[0028] By setting the limit device, when limiting the ball valve body 12, the hydraulic rod is started to control the fixed round block 21 to move downward until the extrusion block 3 squeezes the fixed cylinder, the extrusion block 3 will move upward, and the starting switch 4 will be squeezed. The starting switch 4 will control the adjustment motor 5 to start, so that the rotating shaft on the adjustment motor 5 drives the rotating rod 51 and the driving gear 52 to rotate, and the driving gear 52 drives the driven gear 62 to rotate. When the driven gear 62 rotates, the adjustment rod 6 will rotate, and the two limit rods 7 are controlled to move horizontally toward each other until the limit rods 7 are against the inner side of the fixed cylinder, and then the electric telescopic rod 15 is started to move the two limit plates 16 downward to clamp the two sides of the ball valve body 12, and then the control motor 14 is started, and the rotating shaft of the control motor 14 drives the rotating disk 11 to rotate, thereby driving the ball valve body 12 to rotate, so as to facilitate the all-round assembly of the ball valve body 12, thereby achieving the effect of facilitating the all-round assembly of the ball valve.

[0029] Working principle: when limiting the ball valve body 12, the hydraulic rod is started to control the fixed round block 21 to move downward until the extrusion block 3 squeezes the fixed cylinder, the extrusion block 3 will move upward, and the starting switch 4 will be squeezed. The starting switch 4 controls the adjustment motor 5 to start, so that the rotating shaft on the adjustment motor 5 drives the rotating rod 51 and the driving gear 52 to rotate, and the driving gear 52 drives the driven gear 62 to rotate. When the driven gear 62 rotates, the adjusting rod 6 rotates, and the two limit rods 7 are controlled to move horizontally toward each other until the limit rods 7 are against the inner side of the fixed cylinder, and then the electric telescopic rod 15 is started to move the two limit plates 16 downward to clamp the two sides of the ball valve body 12, and then the control motor 14 is started, and the rotating shaft of the control motor 14 drives the rotating disk 11 to rotate, thereby driving the ball valve body 12 to rotate, and after rotating to a suitable position, the control motor 14 and the electric telescopic rod 15 are turned off, and the limit plate 16 moves up, which will not hinder the assembly.
