Description

Technical Field

[0001] The invention belongs to the technical field of ball valve stems, and in particular relates to a processing device for a ball valve stem. Background Art

[0002] A ball valve is a valve whose opening and closing member (ball) is driven by the valve stem and rotates around the ball valve axis. It has the following notable characteristics: low fluid resistance, simple and compact structure, good sealing, and convenient and quick operation. The ball channel is consistent with the inner diameter of the pipe, and the fluid passes through with almost no obstruction and low pressure loss. It is composed of only a few parts such as the valve body, valve cover, ball, valve stem and seals, which not only requires little installation space but also facilitates maintenance and repair.

[0003] The ball valve stem is one of the key components of the ball valve. It undertakes the important task of connecting the operating device and the ball valve, and plays the role of transmitting the operating torque and driving the ball to rotate to realize the opening and closing of the valve or flow regulation. During the production and processing of the ball valve stem, it needs to be fixed with a clamping device to prevent the valve stem from moving during the processing and causing processing deviations. Although the existing clamping device can achieve the basic fixing function of the valve stem to a certain extent, due to the continuous expansion and diversification of the application fields of ball valves, the models of ball valves are also becoming increasingly rich, and the sizes of valve stems corresponding to different models of ball valves are also different. The existing clamping device is difficult to adapt to such diverse needs due to its relatively simple design structure and limited adjustment range. When facing valve stems of different specifications, it is often necessary to frequently replace the clamp or perform complex adjustment operations, which not only increases production costs and time costs, but may also lead to poor fixing effect due to improper adjustment, affecting the processing quality of the valve stem. Therefore, it is necessary to improve it. Summary of the Invention

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0021] like Figures 1 to 8As shown, an embodiment of the present invention provides a processing device for a ball valve stem, including a lifting plate 1, a first support plate 2 is fixedly installed on the left side of the top of the lifting plate 1, a movable shaft sleeve 3 is movably sleeved inside the top of the first support plate 2, a mounting plate 4 is fixedly connected to the right side of the movable shaft sleeve 3, a first clamping block 5 is movably connected to the top and bottom of the right side of the mounting plate 4, a second support plate 6 is fixedly installed on the right side of the top of the lifting plate 1, a movable frame 7 is movably installed on the top of the left side of the second support plate 6, a fixed plate 8 is fixedly installed on the left side of the movable frame 7, and a connecting plate 9 is movably sleeved inside the front and rear ends of the fixed plate 8, and a fixing plate 9 is fixedly installed between the connecting plates 9. A second clamping block 10 is located on the left side of the fixed plate 8, and anti-slip pads 11 are fixedly installed on the inner sides of the second clamping block 10 and the first clamping block 5. A fixed frame 12 located inside the movable frame 7 is fixedly installed on the right side between the connecting plates 9. A driving motor 13 is fixedly installed on the top of the movable frame 7. The other end of the output shaft of the driving motor 13 is fixedly connected to a circular shaft 14. The bottom end of the circular shaft 14 extends to the interior of the movable frame 7 and is movably connected to the inner wall of the movable frame 7. The outer surface of the circular shaft 14 is fixedly connected to the first circular disc 15, and the inside of the right end of the first circular disc 15 is fixedly connected to a vertical rod 16. The outer surface of the vertical rod 16 is movably connected to the inner surface of the fixed frame 12.

[0022] There are two first clamping blocks 5, and the two first clamping blocks 5 have the same size as the second clamping blocks 10. When the driving motor 13 is started, the circular shaft 14 will drive the first disc 15 to rotate, so that the vertical rod 16 can rotate with the circular shaft 14 as the axis, and then squeeze and push the inner surface of the fixed frame 12, thereby driving the fixed frame 12 to move to the left, so that the fixed frame 12 drives the second clamping block 10 to move to the left through the two connecting plates 9, so that the second clamping block 10 cooperates with the first clamping block 5, and can clamp and fix valve stems of different diameters. Due to the design of the anti-slip pad 11, the anti-slip pad 11 can play an anti-slip role, and at the same time avoid damage to the surface of the valve stem when clamping and fixing the valve stem.

[0023] Among them, the bottom of the vertical rod 16 is fixedly connected to a second disc 17 located inside the movable frame 7, and the interior of the second disc 17 is movably connected to a fixed shaft 18. The bottom of the fixed shaft 18 extends to the interior of the movable frame 7 and is fixedly connected to the inner wall of the movable frame 7. The outer surface of the second disc 17 is movably connected to the bottom of the fixed frame 12.

[0024] When the vertical rod 16 rotates around the circular shaft 14 , it drives the second circular disc 17 to rotate, thereby making the fixed frame 12 more stable when moving leftward.

[0025] Among them, a power motor 19 is fixedly installed on the top of the right side of the second support plate 6, and the other end of the output shaft of the power motor 19 is fixedly connected to the rotating shaft 20. The left end of the rotating shaft 20 is fixedly connected to the outer surface of the movable frame 7, and the outer surface of the rotating shaft 20 is movably connected to the inner wall of the second support plate 6.

[0026] When the power motor 19 is started, the rotating shaft 20 will drive the movable frame 7 to rotate, thereby causing the second clamping block 10 to rotate. After the second clamping block 10 and the first clamping block 5 clamp the valve stem, the rotation of the second clamping block 10 will drive the valve stem to rotate, thereby facilitating the operator to perform more comprehensive processing on the valve stem.

[0027] A slider 21 is fixedly mounted on the left side of the first clamping block 5 , and the outer surface of the slider 21 is movably sleeved with the inner wall of the mounting plate 4 .

[0028] By providing the slider 21 , the slider 21 can limit the first clamping block 5 , so that the first clamping block 5 can move up and down, thereby preventing the first clamping block 5 from rotating.

[0029] There are two sliders 21 , and a tooth plate 22 is fixedly installed on the left side of each slider 21 . The outer surface of the tooth plate 22 is movably connected to the inner surface of the mounting plate 4 .

[0030] When the two tooth plates 22 move toward each other, the two first clamping blocks 5 will be driven to move toward each other through the slider 21, so that valve stems of different lengths can be clamped and fixed, and the clamped position of the valve stem can be adjusted to avoid affecting the operator's processing.

[0031] Among them, a fixed motor 23 is fixedly installed on the left side of the mounting plate 4, and the other end of the output shaft of the fixed motor 23 is fixedly connected to a rotating shaft 24. The outer surface of the rotating shaft 24 is movably sleeved with the inner wall of the mounting plate 4, and the outer surface of the rotating shaft 24 is fixedly sleeved with a gear 25 located inside the mounting plate 4, and the outer surface of the gear 25 is meshed with the outer surface of the tooth plate 22.

[0032] The operator starts the fixed motor 23, so that the rotating shaft 24 drives the gear 25 to rotate. When the gear 25 rotates, it engages with the outer surface of the tooth plate 22, which will drive the two tooth plates 22 to move toward each other, thereby adjusting the position of the first clamping block 5 through the slider 21.

[0033] Among them, limit blocks 26 are fixedly installed on the left and right sides of the lifting plate 1. There are two limit blocks 26 with the same size. The outer surface of the limit block 26 is movably connected to the limit plate 27.

[0034] By setting the limit block 26 and the limit plate 27, the limit block 26 and the limit plate 27 cooperate with each other, so as to limit the lifting plate 1, so that the lifting plate 1 can rise and fall stably, thereby adjusting the height of the valve stem.

[0035] Among them, a bottom plate 28 is fixedly installed at the bottom of the limit plate 27, an adjusting motor 29 is fixedly installed at the bottom of the right side of the limit plate 27, and the other end of the output shaft of the adjusting motor 29 is fixedly connected to a double-threaded rod 30. The left end of the double-threaded rod 30 passes through the limit plate 27 and is movably connected to the inner wall of the limit plate 27.

[0036] The operator can start the adjustment motor 29 to allow the double-threaded rod 30 to rotate, and the threads on the left and right sides of the outer surface of the double-threaded rod 30 are in opposite directions.

[0037] The left and right sides of the outer surface of the double-threaded rod 30 are both threadedly sleeved with moving blocks 31 , and the bottom of the moving block 31 is movably connected to the top of the bottom plate 28 .

[0038] Since the threads on the left and right sides of the outer surface of the double-threaded rod 30 are in opposite directions, when the double-threaded rod 30 rotates, it can drive the two moving blocks 31 to move toward or away from each other.

[0039] The top of the moving block 31 is hinged with a hinge rod 32 . There are two hinge rods 32 . The tops of the two hinge rods 32 are hinged to the bottom of the lifting plate 1 .

[0040] When the two moving blocks 31 move toward each other, the hinge rod 32 is driven to move, so that the hinge rod 32 pushes the lifting plate 1 to move upward under the limiting action of the limiting plate 27 and the limiting block 26 .

[0041] Working principle and usage process: The operator places the valve stem to be clamped and fixed between the first clamping block 5 and the second clamping block 10, and then starts the drive motor 13 to make the circular shaft 14 drive the first disc 15 to rotate, so that the vertical rod 16 rotates with the circular shaft 14 as the axis, and then squeezes and pushes the inner surface of the fixed frame 12, so that the fixed frame 12 moves to the left. The fixed frame 12 will drive the second clamping block 10 to move to the left through the connecting plate 9, so that the second clamping block 10 cooperates with the first clamping block 5 to clamp and fix valve stems of different diameters.

[0042] When valve stems of different lengths need to be clamped and fixed, the fixing motor 23 is started so that the rotating shaft 24 drives the gear 25 to rotate, thereby causing the gear 25 to drive the two tooth plates 22 to move toward each other, and then the slider 21 drives the two first clamping blocks 5 to move toward each other, so that the distance between the first clamping blocks 5 changes, thereby enabling the valve stem of smaller length to be clamped and fixed.

[0043] When the valve stem is clamped and fixed, the operator can start the power motor 19 to make the rotating shaft 20 drive the movable frame 7 to rotate, thereby causing the second clamping block 10 to rotate. The rotation of the second clamping block 10 will drive the valve stem to rotate forward or backward within a range of one hundred and eighty degrees, thereby adjusting the inclination angle of the valve stem, making it convenient for the operator to perform more comprehensive processing on the valve stem. When it is necessary to adjust the height of the valve stem, the adjusting motor 29 is started to rotate the double-threaded rod 30, thereby driving the two moving blocks 31 to move toward each other. At this time, as the moving block 31 moves, the lifting plate 1 will be pushed upward by the articulated rod 32 under the limiting action of the limit block 26, thereby causing the first support plate 2 and the second support plate 6 to rise, thereby adjusting the height of the valve stem, making it convenient for the operator to perform processing.
