[0002] A ball valve is a type of valve used in pipelines to control the flow and shut-off of fluids. A ball valve typically consists of a valve body, a valve core inside the valve body, and a shaft connected to the valve core for controlling its rotation. Plastic ball valves are a common type of ball valve and are suitable for shut-off operations in processes involving the transport of corrosive media.

[0003] Chinese Patent Publication No. CN219383965U discloses a ball valve oil injection and transfer device. Its key technical features include: a support frame for connection to an external equipment frame; a track plate on the support frame; a linear guide rail on the track plate; a sliding seat connected to the guide rail; a lifting seat connected to one side of the sliding seat; a clamping member on the lifting seat for gripping the ball valve; driving components connected to the sliding seat and the lifting seat, which, together with the clamping member, constitute a ball valve transfer mechanism; and an oil injection cylinder located directly above the clamping member on the lifting seat, capable of injecting lubricating oil into the ball valve located on the clamping member.

[0004] In the above technical solution, after the lubricating oil is injected into the ball valve, it cannot be evenly distributed within the ball valve.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0031] like Figures 1 to 2As shown, an oil injection device for a ball valve includes a workbench 1, a positioning base plate 2 on the workbench 1, a plurality of positioning sleeves 3 for placing the ball valve on the positioning base plate 2, four support columns 4 on the workbench 1, the four support columns 4 being symmetrically distributed along the center of the workbench 1, an upper sliding assembly on the four support columns 4, an oil injection assembly for injecting oil into the ball valve and a lifting assembly for linear displacement of the oil injection assembly on the upper sliding assembly, a lifting plate 5 on the lifting assembly and the oil injection assembly, a plurality of clamping assemblies for fixing the ball valve on the lifting plate 5, a plurality of rotating assemblies below the clamping assemblies, and the rotating assemblies being located at both ends of the positioning base plate 2.

[0032] This device works in conjunction with a robotic arm, which is a standard piece of equipment and will not be described in detail. After the robotic arm places the ball valve onto the positioning sleeve 3, the upper sliding component moves the oiling component and the lifting component above the ball valve. The lifting component lowers the oiling component via the lifting plate 5. The clamping component clamps and fixes the top of the ball valve. The rotating component abuts against the side of the ball valve. The oiling component injects oil into the ball valve. At the same time, the rotating component rotates the ball valve's core accordingly, allowing the entire surface of the core to be fully oiled. After oiling, the rotating component releases the side of the ball valve, while the clamping component continues to clamp the top of the ball valve. The lifting component raises the clamping component via the lifting plate 5, causing the ball valve to detach from the positioning sleeve 3. The upper sliding component moves the clamping component to the discharge position. When the displacement reaches the discharge position, the clamping component releases the ball valve, causing it to fall off the clamping component and complete the discharge.

[0033] like Figures 1 to 2 As shown, a positioning side plate 6 is provided at both ends of the positioning sleeve 3. Both positioning side plates 6 are bolted to the positioning base plate 2. Several positioning holes 7 for positioning ball valves are opened on both positioning side plates 6.

[0034] The positioning side plate 6 and the positioning sleeve 3 work together to provide corresponding support points for the top and side of the ball valve. The shape of the positioning hole 7 matches the shape of the side of the ball valve, further enhancing the stability of the ball valve when placed on the positioning side plate 6.

[0035] like Figures 1 to 2 As shown, the upper sliding assembly includes an upper slide rail 8, an upper slider 9, a sliding plate 10, a sliding cylinder 11, and a sliding mounting plate 12. There are two upper slide rails 8, which are respectively set on the top of two support columns 4 on the same side. There are several upper sliders 9, which are respectively slidably connected to the two upper slide rails 8, and their top bolts are fixed to the sliding plate 10. The sliding cylinder 11 is set on the side of one upper slide rail 8. The top bolt of the sliding mounting plate 12 is fixed to the sliding plate 10, and its bottom bolt is fixed to the sliding cylinder 11.

[0036] The upper slide rail 8 provides corresponding support for other parts of the upper sliding assembly. Driven by the sliding cylinder 11, it drives the upper slider 9 to slide accordingly. The sliding of the upper slider 9 can drive the upper slider 9 to make corresponding displacements.

[0037] like Figures 3 to 4 As shown, the oil injection assembly includes an oil storage tank 13, an oil injection pipe 14, and an oil injection valve 15. There are several oil storage tanks 13, which are symmetrically distributed along the center of the sliding plate 10. The tank body of the oil storage tank 13 passes through the sliding plate 10. There are several oil injection pipes 14, which are installed on the oil storage tank 13. There are several oil injection valves 15, which are installed on the oil injection pipes 14.

[0038] The number of oil storage tanks 13 can be adjusted according to the number of ball valves to be processed. The oil storage tanks 13 can store lubricating oil. The lubricating oil can enter the oil injection valve 15 from the oil storage tanks 13 through the oil injection pipe 14. When the lifting component moves the oil injection component downward, the oil injection valve 15 enters the ball valve and injects oil into the ball valve.

[0039] like Figures 3 to 4 As shown, the lifting assembly includes a lifting cylinder 16, a lifting connector 17, and guide rods 18. The lifting cylinder 16 is located on the top of the sliding plate 10, and its output shaft passes through the sliding plate 10. The lifting connector 17 is located on the piston rod of the lifting cylinder 16 and is bolted to the lifting plate 5. There are four guide rods 18, which pass through the sliding plate 10 through connecting sleeves and are fixedly connected to the lifting plate 5 at their bottom.

[0040] The lifting cylinder 16 generates force, and the piston rod of the lifting cylinder 16 transmits the force to the lifting plate 5. The lifting plate 5 is driven to rise and fall through the lifting joint 17. The guide rod 18 is a movable guide rod 18, which can be stably installed on the sliding plate 10 through the connecting sleeve. The guide rod 18 moves synchronously with the piston rod of the lifting cylinder 16, which improves the stability of the lifting plate 5 during the lifting process and prevents it from shaking or deviating during the lifting process.

[0041] like Figures 3 to 4 As shown, the clamping assembly includes a clamping cylinder 19 and clamping fingers 20. The clamping cylinder 19 is located at the bottom of the lifting plate 5, on one side of the oil injection valve 15. The specific number of clamping fingers 20 is two, and the two clamping fingers 20 are set on the clamping cylinder 19.

[0042] When the lifting plate 5 descends to the top of the ball valve, the clamping cylinder 19 controls the two clamping fingers 20 to move closer to each other, which clamps and fixes the top of the ball valve, so that the oil injection valve 15 remains stable during the oil injection process of the ball valve. The clamping fingers 20 are arc-shaped and fit against the top of the ball valve.

[0043] like Figure 5 As shown, the rotating assembly includes a rotating base plate 21, a rotating positioning plate 22, and a rotating shaft 23. The rotating base plate 21 is disposed above the worktable 1 and is slidably connected to the worktable 1 through a sliding assembly. There are several rotating positioning plates 22, which are bolted to the top of the rotating base plate 21. There are several rotating shafts 23, which are rotatably connected to the rotating positioning plates 22 and are rotated by a drive assembly.

[0044] The rotating base plate 21 provides corresponding support for the rotating positioning plate 22. The rotating positioning plate 22 and the rotating shaft 23 on the rotating base plate 21 can be moved away from or closer to the ball valve by sliding the sliding component. The rotating positioning plate 22 plays a corresponding positioning role for the rotating shaft 23. The rotating shaft 23 can abut against the side of the ball valve and play a rotating role. The rotating shaft 23 is driven by the drive component to make it rotate accordingly.

[0045] like Figure 5 As shown, the sliding assembly includes a sliding rail 24, a sliding block 25, a drive cylinder 26, and a drive connecting plate 27. There are two sliding rails 24, which are located at both ends below the rotating base plate 21. There are several sliding blocks 25, which are slidably connected to the two sliding rails 24. The top of the sliding block 25 is bolted to the rotating base plate 21. The drive cylinder 26 is located on the upper surface of the worktable 1. The bottom of the drive connecting plate 27 is bolted to the drive cylinder 26, and the top of the drive connecting plate 27 is bolted to the rotating base plate 21.

[0046] The driving cylinder 26 generates a force that causes the driving connecting plate 27 to move linearly. The driving connecting plate 27 drives the lower slider 25 on the lower slide rail 24 to move accordingly. At the same time, it can drive the rotating base plate 21 to move. The displacement of the rotating base plate 21 can drive the rotating shaft 23 on it to move closer to or away from the ball valve.

[0047] like Figure 5 As shown, the drive assembly includes a drive wheel 28, a first driven wheel 29, a first synchronous belt 30, a second driven wheel 31, a second synchronous belt 32, a rotary motor 33, and a connecting base plate 34. The drive wheel 28 is mounted on the output shaft of the rotary motor 33. The first driven wheel 29 is rotatably connected to a rotating shaft 23. One end of the first synchronous belt 30 is rotatably connected to the drive wheel 28, and the other end is rotatably connected to the first driven wheel 29. There are several second driven wheels 31, which are rotatably connected to several rotating shafts 23 respectively. The second synchronous belt 32 is rotatably connected to several second driven wheels 31. The top bolts of the connecting base plate 34 are fixed to the rotating base plate 21, and the bottom bolts are fixed to the rotary motor 33.

[0048] The rotary motor 33 drives the drive wheel 28 to rotate via its output shaft. The drive wheel 28 drives the first driven wheel 29 to rotate via the first synchronous belt 30. The rotation of the first driven wheel 29 can drive one of the rotating shafts 23 on the rotating base plate 21 to rotate. This rotating shaft 23 is perpendicular to the rotary motor 33 in the vertical direction. The second driven wheel 31 is provided on each rotating shaft 23. The rotating shaft 23 perpendicular to the rotary motor 33 has both the first driven wheel 29 and the second driven wheel 31. Through the rotating shaft 23 perpendicular to the rotary motor 33, the second driven wheel 31 and the second synchronous belt 32 can drive the other rotating shafts 23 to rotate. The rotating shaft 23 drives the side of the ball valve to rotate, so that the entire surface of the ball core can be fully oiled.

[0049] like Figure 1 As shown, a discharge port 35 is bolted to the bottom of the workbench 1. After the oil is injected, the ball valve can leave the equipment through the discharge port 35. The discharge port 35 is designed with a slope so that the ball valve can be buffered after leaving the equipment, reducing the loss during the feeding process.

[0050] Working principle: After the robotic arm places the ball valve onto the positioning sleeve 3, the sliding cylinder 11 drives the upper slider 9 to move the sliding plate 10 above the ball valve. The lifting cylinder 16 moves the lifting plate 5 downward through the lifting joint 17. When the lifting plate 5 abuts against the top of the ball valve, the lifting cylinder 16 stops working. The clamping cylinder 19 controls the clamping fingers 20 to clamp and fix the top of the ball valve. The driving cylinder 26 moves the rotating base plate 21, rotating positioning plate 22, and rotating shaft 23 above the driving connecting plate 27 through the lower slider 25. The rotating shaft 23 abuts against the side of the ball valve. The oil injection valve 15 injects oil into the ball valve. At the same time, the rotary motor 33 drives the drive wheel 28 to rotate through the output shaft. The drive wheel 28 drives the first driven wheel 28 through the first synchronous belt 30. The driving wheel 29 rotates accordingly. The rotating shaft 23, equipped with the driving wheel 28, drives other rotating shafts 23 to rotate via the second driven wheel 31 and the second synchronous belt 32. The rotating shaft 23 drives the side of the ball valve to rotate, allowing the entire surface of the ball core to be fully oiled. After the entire surface of the ball core is fully oiled, the rotating shaft 23 moves away from the side of the ball valve, while the clamping finger 20 still clamps the top of the ball valve. The lifting cylinder 16 drives the lifting plate 5 to rise via the lifting joint 17, causing the ball valve to disengage from the positioning sleeve 3. The sliding cylinder 11 drives the upper slider 9 to move the sliding plate 10 to above the discharge port 35. The clamping finger 20 releases the ball valve, and the ball valve falls off the clamping finger 20 and enters the discharge port 35, completing the discharge.

[0051] The specific embodiments are merely explanations of this utility model and are not intended to limit it.
