Description

Technical Field

[0001] This utility model relates to ball valves, and more specifically, to a main arm fixture for picking up and placing ball valves. Background Technology

[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] In existing technologies, such as Figure 5 As shown, the ball valve processing equipment includes a processing equipment body 27. The processing equipment body 27 is equipped with several positioning rods 28 and positioning rings 29. During the material handling process, the positioning rings 29 pop out, which facilitates the unloading device to grab the processed ball valve. However, the positioning rings 29 cannot be reset. When the unprocessed ball valve is placed on the positioning rods 28 and positioning rings 29, it is easy to fall off.

[0004] Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Utility Model Content

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] 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.

[0028] like Figures 1 to 3 As shown, a main arm fixture for picking up and placing ball valves includes a worktable 1. The upper surface of the worktable 1 has several gripper holes 2. Each gripper hole 2 is equipped with a gripper cylinder 3. Each gripper cylinder 3 is equipped with several pneumatic grippers 4. Each end of the upper surface of the worktable 1 away from the pneumatic grippers 4 is equipped with several support columns 5. Each support column 5 is fitted with a reset ring 6. The reset ring 6 is equipped with a drive mechanism for driving the displacement of the reset ring 6. A linear displacement mechanism is provided at the bottom of the worktable 1. A rotation mechanism is provided on the linear displacement mechanism.

[0029] The ball valve is clamped or released by several pneumatic grippers 4 controlled by the gripper cylinder 3 to complete the material picking and unloading. The support column 5 provides support for the reset ring 6. The reset ring 6 is displaced by the drive mechanism, which can reset the positioning ring 29 in the prior art. When the unprocessed ball valve is placed on the positioning rod 28 and the positioning ring 29, it is not easy to fall off. The linear displacement mechanism allows the components on the worktable 1 to move closer to or further away from the processing equipment body 27, which helps the pneumatic grippers 4 to grasp and reset the positioning ring 29. The rotation mechanism can realize the conversion between the pneumatic grippers 4 and the reset ring 6, improving the operating efficiency.

[0030] like Figures 1 to 3 As shown, there are three pneumatic grippers 4. Each of the three pneumatic grippers 4 has a mounting plate 7 bolted to its bottom. The mounting plates 7 are all located on the surface of the gripper cylinder 3.

[0031] The three-point contact forms a stable geometric plane, which can effectively prevent the ball valve from sliding or rotating due to uneven force during the gripping process. Compared with two-jaw gripping, the three-jaw system can evenly distribute the gripping force at 120° intervals of contact points, reduce local pressure, and prevent surface damage. The pneumatic gripper 4 can be stably installed on the gripper cylinder 3 through the mounting plate 7, so as to realize flexible gripping of the ball valve.

[0032] like Figures 1 to 3 As shown, the drive mechanism includes a drive plate 8 and a drive cylinder 9. The upper surface of the drive plate 8 is bolted to the bottom of the reset ring 6. The drive cylinder 9 is located on the lower surface of the worktable 1, and its output shaft passes through the worktable 1 and is connected to the drive plate 8. A guide rod 10 is provided at both ends of the bottom of the drive plate 8. Both guide rods 10 pass through the worktable 1 and are fixed to the worktable 1 by guide rod sleeves.

[0033] The guide rod 10 is a movable guide rod. The guide rod sleeve is fitted onto the guide rod 10 and bolted to the worktable 1. The top of the guide rod 10 is bolted to the drive plate 8. The guide rod 10 can move synchronously with the piston rod of the drive cylinder 9. The drive cylinder 9 is installed below the worktable 1, and its output shaft passes vertically through the worktable 1 and is connected to the drive plate 8. The drive cylinder 9 outputs power to drive the drive plate 8 to move several reset rings 6. The specific number of reset rings 6 is four, which are set at the four corners of the upper surface of the drive plate 8. The reset rings 6 can reset the positioning ring 29 in the prior art. The guide rod 10 can improve the overall stability of the drive mechanism during displacement, so that the drive plate 8 will not shake or deviate.

[0034] like Figures 1 to 3 As shown, an installation groove 11 is provided on the outer circumference of the support column 5, and a limiting plate 12 is provided on the installation groove 11. The limiting plate 12 is bolted to the inner wall of the support column 5. A limiting hole 13 is provided on the circumference of the reset ring 6, and the limiting hole 13 cooperates with the limiting plate 12.

[0035] The limiting hole 13 and the limiting plate 12 work together to prevent the reset ring 6 from falling off during movement, effectively limiting the maximum stroke of the reset ring 6 and achieving a good limiting effect.

[0036] like Figure 4 As shown, the linear displacement mechanism includes a displacement base 14, a displacement rotation shaft 15, a displacement rotation plate 16, a displacement cylinder 17, and a displacement mounting plate 18. The displacement base 14 is located below the worktable 1. The bottom of the displacement rotation shaft 15 abuts against the displacement base 14, and its top is fixedly connected to the displacement rotation plate 16. The displacement rotation plate 16 is fixedly connected to the bottom of the worktable 1 and is located at the center of the bottom of the worktable 1. The output shaft of the displacement cylinder 17 is fixedly connected to the displacement base 14, and the top of the displacement mounting plate 18 is bolted to the displacement cylinder 17.

[0037] In use, the retraction of the output shaft of the displacement cylinder 17 causes the displacement base 14 to fully abut against the displacement rotating shaft 15. The displacement rotating shaft 15 drives the displacement rotating plate 16 to rise and fall, causing the worktable 1 and the components on the worktable 1 to move accordingly, thereby driving the gripping and releasing ball valve and resetting. When the output shaft of the displacement cylinder 17 extends, it can drive the worktable 1 and the components on the worktable 1 to return to their original positions.

[0038] like Figure 4As shown, the rotating mechanism includes a rotating connecting plate 19, a telescopic sleeve 20, a telescopic spring rod 21, a driving pulley 22, a driven pulley 23, a synchronous belt 24, a rotary motor 25, and a rotating mounting plate 26. The rotating connecting plate 19 has a rotating groove for inserting a displacement rotating shaft 15, and its top is bolted to the bottom of the displacement mounting plate 18. There are two telescopic sleeves 20, located at both ends of the bottom of the rotating connecting plate 19. There are also two telescopic spring rods 21. One end of 1 is elastically connected to a telescopic sleeve 20, and the other end is fixedly connected to the displacement base 14. The driving pulley 22 and the driven pulley 23 are both set on the upper surface of the rotating connecting plate 19. The driven pulley 23 is rotatably connected to the displacement rotating shaft 15. One end of the synchronous belt 24 is rotatably connected to the driving pulley 22, and the other end is rotatably connected to the driven pulley 23. The rotary motor 25 is rotatably connected to the driving pulley 22. The top bolt of the rotary mounting plate 26 is fixed to the rotary motor 25, and the top bolt of the rotary mounting plate 26 is fixed to the rotary connecting plate 19.

[0039] The drive pulley 22 is driven to rotate by the rotary motor 25. The drive pulley 22 drives the driven pulley to rotate through the synchronous belt 24, and enables the displacement rotation shaft 15 to rotate. The displacement rotation shaft 15 transmits power to the worktable 1 through the displacement rotation plate 16, enabling the worktable 1 to rotate and realize the conversion between the reset ring 6 and the pneumatic gripper 4.

[0040] Working principle: During use, the retraction of the output shaft of the displacement cylinder 17 causes the displacement base 14 to fully abut against the displacement rotating shaft 15. The displacement rotating shaft 15 drives the displacement rotating plate 16 to rise and fall, causing the worktable 1 and the components on the worktable 1 to move accordingly. The gripper cylinder 3 drives the pneumatic gripper 4 to grip the ball valve. After gripping, the output shaft of the displacement cylinder 17 extends, causing the worktable 1 and the components on the worktable 1 to return to their original positions. The rotary motor 25 drives the drive pulley 22 to rotate. The drive pulley 22 drives the driven pulley to rotate through the synchronous belt 24, enabling the displacement rotating shaft 15 to rotate. The displacement rotating shaft 15 transmits power to the worktable 1 through the displacement rotating plate 16, enabling the entire worktable 1 to rotate, realizing the conversion between the reset ring 6 and the pneumatic gripper 4. The drive cylinder 9 generates force to cause the drive plate 8 to drive several reset rings 6 to move. The displacement of the reset rings 6 causes the positioning ring 29 to reset accordingly.
