Abstract
Description
Technical Field
[0001] This invention relates to the field of valve body processing technology, specifically to a valve body processing, cutting, and fixing device and method for a rotary ball valve. Background Technology
[0002] As a key fluid control device, the rotary ball valve plays an irreplaceable role in many industrial fields such as petroleum, chemical, power, and water conservancy. Its valve body, as a core component, directly affects the overall performance, sealing performance, and service life of the rotary ball valve due to its machining precision and quality. In today's industrial production, which is constantly developing towards higher precision, higher efficiency, and higher quality, more stringent requirements are placed on the machining of rotary ball valve bodies. The valve body not only needs precise dimensions and shapes to meet the need for accurate assembly with other valve components, but also needs good surface quality to effectively resist fluid erosion and corrosion in complex working environments, thereby ensuring stable valve operation. Traditional valve body machining methods mostly rely on general-purpose machine tools. During machining, the clamping and positioning of the valve body often employs relatively simple and fixed methods. However, rotary ball valve bodies typically have complex shapes and structures, making this traditional machining method difficult to fully adapt to the characteristics of the valve body, thus limiting its ability to guarantee machining precision and efficiency.
[0003] Existing technologies still have some inconveniences. Traditional clamping methods are extremely limited, mostly only able to clamp valve body materials from both sides. When dealing with valve body materials that are complex in shape, have uneven surfaces, or are of inconsistent texture, this simple clamping method cannot provide sufficient stability. During processing, the material is prone to shaking and shifting. For example, during cutting operations, the shaking of the material can cause the cutting path to shift, resulting in inaccurate cutting dimensions, seriously affecting processing accuracy, and consequently leading to a significant increase in product defect rates, causing unnecessary economic losses to the company. Moreover, when it is necessary to adjust the processing surface of the material, the operation of traditional devices is extremely cumbersome, often requiring manual assistance from workers. This is not only inefficient and greatly extends the processing cycle, but also increases the labor intensity of workers. Manual operation presents numerous safety hazards, with workers potentially injured due to negligence. Furthermore, traditional devices lack flexible mechanical structures to support precise vertical and horizontal flipping of raw materials, failing to meet diverse processing needs and limiting the processing range and quality improvement of products. In addition, the design of ventilation components in existing technologies is unreasonable, preventing timely and effective removal of debris generated during cutting, which quickly accumulates in the work area, hindering the normal operation of the cutting equipment and potentially interfering with cutting accuracy. Simultaneously, the lack of effective airflow guidance at the material clamping position prevents the timely removal of heat generated during processing, leading to uneven heating of the material, thermal stress, and severely affecting the overall performance and quality of the valve body, thus shortening its service life. Summary of the Invention

[0006] Furthermore, the inner bottom surface of the outer shell is also provided with four side telescopic motors, the output shaft end of the side telescopic motor is provided with a lifting plate, the upper surface center of the lifting plate is provided with a bearing rotating disk, the bottom surface of the lifting plate is provided with a bottom storage box, the inner bottom surface of the bottom storage box is provided with a lifting telescopic rod, the output shaft end of the lifting telescopic rod is provided with a bottom adjustment motor, the output shaft end of the bottom adjustment motor is connected to the bottom surface of the bearing rotating disk, and both sides of the lifting plate are provided with auxiliary clamping assemblies.
[0007] Furthermore, the auxiliary clamping assembly includes: a fixed frame, the bottom surface of which is connected to the upper surface of the support platform; a slidable sliding plate is provided at the center of the fixed frame; multiple connecting springs are provided between the sliding plate and the inner side surface of the fixed frame; a connecting rod is provided on the upper surface of the sliding plate; a main electric shaft is provided in the middle section of the connecting rod; a clamping plate is provided on the upper surface of the connecting rod; and two top telescopic rods are provided on the upper surface of the clamping plate.
[0008] Furthermore, the output shaft ends of the two top telescopic rods are provided with clamping auxiliary plates. The surfaces of the clamping block and the clamping auxiliary plates are provided with multiple ventilation slots. One side surface of the clamping plate is provided with an electric turntable, and one side surface of the electric turntable is provided with a rotating disk. The rotating disk is located at the center of the clamping auxiliary plate, and a circular hole is provided at the center of the clamping auxiliary plate to facilitate the passage of the rotating disk.
[0009] Furthermore, a side slider is provided on one side surface of the clamping plate, the side slider cooperates with the sliding inclined block, and limiting side blocks are provided on both the upper and lower surfaces of the side slider. A force-bearing side plate is also provided on one side surface of the connecting rod, and an auxiliary electric shaft is also provided on one side of the upper surface of the fixed frame. A small telescopic rod is provided on the upper surface of the auxiliary electric shaft.
[0010] Furthermore, ventilation ducts are provided on one side surface of the two air outlet ports, and two internal air ducts are provided inside the support platform. The two ventilation ducts are respectively connected to one end of the two internal air ducts. Two air outlet openings are opened on the upper surface of the support platform, and the two air outlet openings are respectively connected to the two internal air ducts.
[0011] Furthermore, the cutting assembly also includes a carriage component, which includes: four supporting uprights, all of which are disposed on the inner bottom surface of the outer casing; two sliding frames are disposed on the top surface of the four supporting uprights; a transverse sliding rod is disposed between the two sliding frames; a lifting platform is disposed on the surface of the transverse sliding rod; and a laser cutting head is disposed on one side surface of the lifting platform.
[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. In this solution, a clamping assembly is provided. Two meshing plates are driven by a bidirectional screw to move the clamping block, achieving initial clamping. At the same time, the auxiliary clamping assembly works ingeniously. The linkage design of the sliding wedge and the side slider allows the additional clamping plate to automatically clamp the material on both sides as the clamping block approaches, forming a stable clamping effect on four sides and improving the stability of the clamping. When the material is flipped and adjusted, the small electric shaft, small telescopic rod, electric turntable and other components work together to achieve both lateral flipping of the material and provide sufficient space for vertical flipping in conjunction with the main and auxiliary electric shafts. This avoids the limitations of traditional clamping devices in flipping operations and can flexibly adapt to different processing needs, providing a reliable guarantee for the high-precision processing of the rotary ball valve body. 2. In this solution, by incorporating ventilation components, air is drawn in through the air intake box and blown outwards towards the cutting area, effectively removing cutting debris. The debris enters the air intake box through the air inlet, where an internal intercepting net precisely intercepts the debris and directs it into the waste collection box for storage, achieving efficient debris collection. Simultaneously, after passing through the intercepting net, the air flows through the air outlet, ventilation duct, and internal duct before finally exiting through the air outlet, cooling the side surface of the raw material at the clamping position and reducing the impact of thermal stress. This ventilation method, which integrates debris removal and raw material cooling, solves the problem of raw material deformation due to heat during traditional cutting processes. 3. In this solution, a sliding frame component is installed, which is stably supported by four support pillars. Two sliding frames and a horizontal sliding rod form a flexible moving frame. The lifting platform is fitted onto the horizontal sliding rod and can move freely in the horizontal and vertical directions. This breaks through the limitation of the fixed position of traditional cutting devices, enabling the laser cutting head to quickly and accurately reach the designated cutting position above the workpiece, improving the flexibility and efficiency of cutting, and providing strong support for the diversified cutting processing of rotary ball valve bodies.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0016] Example 1: Please refer to Figures 1 to 8 A valve body machining, cutting, and fixing device and method for a rotary ball valve, comprising: The outer casing 1, as the basic support structure of the entire device, plays a crucial role. It not only provides stable installation space for the various internal components but also offers a certain degree of protection, effectively preventing external factors from interfering with or damaging the internal precision parts. A sliding door 2 is provided on one side of the outer casing 1. The sliding door 2 is made of high-strength, wear-resistant material and, through a precise track design, can smoothly open and close. The working mechanism is located inside the outer casing 1, including a clamping assembly and a cutting assembly. The clamping assembly includes a support platform 3, which serves as the basic support structure for the entire clamping assembly and has sufficient strength. Sufficient strength and stability are ensured. The support platform 3 is located on the inner bottom surface of the outer shell 1. A motor housing 13 is provided on one side surface of the support platform 3. The motor housing 13 adopts a sealed design to effectively prevent dust, debris, and other impurities from entering the interior, protecting the normal operation of the drive motor 14. The drive motor 14 is installed inside the motor housing 13. A bidirectional screw 15 is provided on the output end of the drive motor 14. A sliding groove 46 is opened on the upper surface of the support platform 3. The bidirectional screw 15 is located inside the sliding groove 46. Two meshing plates 16 mesh with the surface of the bidirectional screw 15. An adjustment motor 40 is provided on the upper surface of the meshing plates 16. The adjustment motor 40... Both sides of the bottom surface are provided with limiting buffer plates 22, which are made of elastic material and can buffer and limit displacement during the operation of the adjusting motor 40. The output shaft of the adjusting motor 40 is provided with a clamping block 21. A small electric shaft 37 is provided on one side surface of the clamping block 21, a sliding inclined block 38 is provided on one side surface of the small electric shaft 37, and a small sliding rod 39 is provided on one side surface of the sliding inclined block 38. The inner bottom surface of the outer shell 1 is also provided with four side telescopic motors 17. The output shaft of the side telescopic motor 17 is provided with a lifting plate 12, which is made of high-strength and lightweight material. Driven by the side telescopic motor 17, the lifting plate 12 is equipped with a bearing rotating disk 41 at the center of its upper surface. The bottom surface of the lifting plate 12 is equipped with a bottom storage box 42. The bottom surface inside the bottom storage box 42 is equipped with a lifting telescopic rod 44. The output shaft end of the lifting telescopic rod 44 is equipped with a bottom adjustment motor 43. The output shaft end of the bottom adjustment motor 43 is connected to the bottom surface of the bearing rotating disk 41. Both sides of the lifting plate 12 are equipped with auxiliary clamping assemblies. As an auxiliary clamping structure, the auxiliary clamping assemblies can further enhance the clamping stability of the raw materials and ensure that the raw materials will not shake or shift during complex processing. In use, the operator places the raw material on the center of the lifting plate 12. Then, they pull the sliding doors 2 on both sides of the outer casing 1 to isolate the working area. Following this, the operator signals the start of the drive motor 14, which rotates the bidirectional screw 15. This meshing action moves two meshing plates 16 inwards, clamping the raw material at the center of the motor housing 13 using two clamping blocks 21. Simultaneously, the auxiliary clamping assembly, along with the two meshing plates 16, works with the clamping blocks 21 to clamp the raw material from all four sides. After clamping, the four side telescopic motors 17 retract under signal control, lowering the lifting plate 12 until it loses contact with the bottom of the raw material. Since the lifting plate 12 is at its highest point when the raw material is placed on its surface, the clamping assembly's position is biased towards the bottom of the surrounding surface, a considerable distance from the cutting position on the upper surface. The cutting assembly then cuts the upper surface of the raw material. In the cutting process, when the processing surface of the raw material needs to be vertically rotated and adjusted, a small electric shaft 37 is driven by a signal to rotate, causing it to lose its linkage with the auxiliary clamping components. Subsequently, the two auxiliary clamping components reset and make room for the rotation of the raw material. Then, the four side telescopic motors 17 are driven by the operator to raise the lifting plate 12 to support the raw material again. Then, the drive motor 14 drives the two meshing plates 16 to separate, causing them to lose their clamping effect on the raw material. Because it is an adjustment of the working surface, the lifting height of the lifting plate 12 will not reach the highest point. At this time, when the two clamping blocks 21 are clamping the raw material, the clamping position is at its center. Then, under the action of the two adjusting motors 40, the raw material is vertically rotated. After rotating, the raw material is placed back on the upper surface of the lifting plate 12. Then, the two clamping blocks 21 reset. At this time, the above clamping steps are repeated to clamp the rotated raw material again, so as to continue the cutting process.
[0017] The auxiliary clamping assembly, as an important component of the entire clamping system, works in conjunction with the main clamping structure to further enhance the clamping stability and flexibility of the valve body material. The auxiliary clamping assembly includes a fixed frame 18, which is made of high-strength, high-rigidity material, capable of withstanding significant external forces without deformation, ensuring the stability of the auxiliary clamping assembly during processing. The bottom surface of the fixed frame 18 is connected to the upper surface of the support platform 3. The fixed frame 18 in the auxiliary clamping assembly acts as a foundation support, providing a stable installation base for the entire auxiliary clamping assembly. A sliding plate 34 is provided at the center of the frame. Multiple connecting springs 35 are provided between the sliding plate 34 and the inner side surface of the fixed frame 18. A connecting rod 32 is provided on the upper surface of the sliding plate 34. The connecting rod 32, as a key part connecting various functional components, has sufficient strength and toughness. A main electric shaft 33 is provided in the middle section of the connecting rod 32. A clamping plate 28 is provided on the upper surface of the connecting rod 32. The clamping plate 28 is one of the key components that directly contacts the raw material for clamping. Two top extensions are provided on the upper surface of the clamping plate 28. The telescopic rod 26 has a clamping auxiliary plate 27 at the end of its output shaft. Multiple ventilation slots 30 are formed on the surfaces of both the clamping block 21 and the clamping auxiliary plate 27. These ventilation slots 30 play a crucial role; during processing, the raw material generates a large amount of heat. The ventilation slots 30 create a good airflow channel, allowing air to quickly flow over the surface of the raw material, carrying away the heat and preventing thermal stress caused by uneven heating, which could affect the overall performance and quality of the valve body. An electric turntable 29 is provided on one side of the clamping plate 28. A rotating disk 31 is provided on the side surface. The rotating disk 31 is located at the center of the clamping auxiliary plate 27. A circular hole is provided at the center of the clamping auxiliary plate 27 to facilitate the passage of the rotating disk 31. A side slider 19 is provided on one side surface of the clamping plate 28. The side slider 19 cooperates with the sliding inclined block 38. Both the upper and lower surfaces of the side slider 19 are provided with limiting side blocks 20. A force-bearing side plate 23 is also provided on one side surface of the connecting rod 32. A secondary electric shaft 36 is also provided on one side of the upper surface of the fixed frame 18. A small telescopic rod 24 is provided on the upper surface of the secondary electric shaft 36. The auxiliary clamping assembly assists the two clamping blocks 21 in stabilizing the material during clamping and in adjusting the material for lateral flipping. When the two clamping blocks 21 approach and clamp the material, the sliding inclined blocks 38 on one side of each clamping block 21 gradually contact the surface of the side slider 19 and slide on the surface of the side slider 19 via small sliding rods 39 on one side. As the two clamping blocks 21 approach, the sliding range of the sliding inclined blocks 38 on the surface of the side slider 19 increases. The two clamping plates 28 also stretch the connecting spring 35 and approach under the pushing action of the sliding inclined blocks 38, clamping both sides of the material via two additional clamping plates 27. This, combined with the two clamping blocks 21, forms a four-sided clamping effect on the bottom surface of the material. When lateral flipping of the material is required, two small telescopic rods 24 extend under the drive of a worker's signal and press against one side surface of the force-bearing side plate 23 through the end of their output shafts. At this time, the sliding inclined block 38 can be flipped by two small electric shafts 37. At this time, the two clamping blocks 21 lose the linkage effect with the clamping plate 28. Then, driven by the drive motor 14, the two clamping blocks 21 move away from each other, making room for the horizontal flipping. At this time, the material is clamped in the middle by the two clamping auxiliary plates 27 using the same method as above. Then, the two top telescopic rods 26 retract, driving the clamping auxiliary plates 27 to move and lose the connection with the side surface of the material. At this time, the two sides of the material are only in contact with the two rotating disks 31. Driven by the electric turntable 29, the two rotating disks 31 can drive the material to flip horizontally, thereby adjusting the processing surface of the material. When the two clamping blocks 21 vertically flip and adjust the material, the main electric shaft 33 and the auxiliary electric shaft 36 can drive the small telescopic rod 24 and the clamping plate 28 to fold, thereby providing a larger vertical folding area and avoiding affecting the vertical adjustment.
[0018] The cutting assembly includes a carriage component and a ventilation component. The carriage component is the foundation for the movement of the cutting assembly, providing a flexible three-dimensional movement space for the laser cutting head 8, ensuring that it can accurately reach the designated position for cutting operations. The carriage component includes: four support rods 5, which are firmly set on the inner bottom surface of the outer shell 1. They are evenly distributed and provide a solid foundation support for the entire carriage component. Two sliding frames 4 are set on the top surface of the four support rods 5. These two sliding frames 4 are parallel to each other and placed horizontally, providing tracks for subsequent lateral and longitudinal movements. A transverse sliding rod 6 is provided between the sliding frames 4. Both ends of the transverse sliding rod 6 are connected to the sliding frames 4 via precision bearings, allowing for smooth transverse sliding on the sliding frames 4. A lifting platform 7 is provided on the surface of the transverse sliding rod 6. The lifting platform 7 adopts a high-precision linear guide and lead screw drive structure, enabling precise vertical lifting motion. A laser cutting head 8 is provided on one side surface of the lifting platform 7. The laser cutting head 8 is the core actuator of the entire cutting assembly. It uses advanced laser technology to emit a high-energy, highly focused laser beam for rapid cutting of the raw material. For fast and precise cutting, ventilation components play a crucial role. They not only promptly disperse cutting smoke and debris, maintaining a clear view of the cutting area, but also cool the cutting area to prevent the raw material from deforming due to overheating. Furthermore, they collect debris for easy cleaning and processing. The ventilation components include an air blower box 9, located on the bottom surface of one of the sliding frames 4, which houses a high-efficiency fan and air duct system. An air inlet box 10 is located on the bottom surface of the other sliding frame 4, with one side surface of the air inlet box 10... It has an air inlet 45, and a waste collection box 25 is provided on the bottom surface of the air inlet box 10 to collect debris blown away by the airflow. An internal interception net 49 is provided inside the air inlet box 10. Two air outlet ports 50 are provided on one side surface of the air inlet box 10. A ventilation duct 11 is provided on one side surface of the two air outlet ports 50. Two internal air ducts 47 are provided inside the support platform 3. The two ventilation ducts 11 are respectively connected to one end of the two internal air ducts 47. Two air outlet openings 48 are opened on the upper surface of the support platform 3. The two air outlet openings 48 are respectively connected to the two internal air ducts 47. In the carriage component of the cutting assembly, four support pillars 5 are stably set on the bottom surface inside the outer shell 1, providing a support base for the entire carriage. Two sliding frames 4 are installed on the top surface of the support pillars 5. A transverse sliding rod 6 connects the two sliding frames 4. A lifting platform 7 is fitted onto the surface of the transverse sliding rod 6. By controlling the transverse movement of the lifting platform 7 on the transverse sliding rod 6, as well as the lifting movement of the lifting platform 7 itself, the position of the laser cutting head 8 in the horizontal and vertical directions can be flexibly adjusted. This dual-dimensional adjustable design allows the laser cutting head 8 to quickly and accurately reach the designated cutting position above the workpiece. In the ventilation component of the cutting assembly, the air blowing box 9 and the air inlet box 10 are respectively set on the bottom surface of the two sliding frames 4. The air blowing box 9 draws in air through multiple fans on one side and blows airflow into the working cutting area, removing the debris generated during cutting. As the air flows, debris enters the air inlet 45 on one side of the air inlet box 10. The internal intercepting net 49 inside the air inlet box 10 can intercept the debris and cause it to fall into the waste collection box 25 below the air inlet box 10 for storage. After passing through the internal intercepting net 49, the air exits through the two air outlets 50 and enters the interior of the two ventilation ducts 11. As it flows inside the ventilation ducts 11, it enters the interior air duct 47 inside the support platform 3 and finally exits from the opening on the upper surface of the interior air duct 47. After exiting the interior air duct 47, the air is blown out from the air outlet 48 and blown towards the bottom surface of the clamping assembly. Through the ventilation grooves 30 on the surface of the clamping block 21 and the clamping auxiliary plate 27, the airflow can come into contact with the side surface of the material being clamped, thereby cooling it and reducing the impact of thermal stress.
[0019] The working principle of this invention is: In use, the operator first places the valve body material at the center of the lifting plate 12, pulls up the sliding doors 2 on both sides of the outer shell 1 to isolate the working area, then controls the drive motor 14 to start, driving the bidirectional screw 15 to rotate. Through the meshing action, the two meshing plates 16 move inward along the sliding channel 46, and the two clamping blocks 21 move closer to each other, initially clamping the bottom surface of the material. At the same time, the sliding inclined block 38 on one side of the clamping block 21 contacts the side slider 19 of the auxiliary clamping assembly, and the small sliding rod 39 slides on the surface of the side slider 19, pushing the clamping plate 28 to pull the connecting spring 35 closer. The two clamping auxiliary plates 27 clamp the two sides of the material, forming a stable four-sided clamping effect in conjunction with the clamping block 21. The four side telescopic motors 17 retract, driving the lifting plate 12 to descend and disengage from the bottom of the raw material. At this time, the cutting assembly is ready to cut the upper surface of the raw material. The four support rods 5 of the cutting assembly provide support for the entire carriage. Two sliding frame bodies 4 are installed on the top surface of the support rods 5, and the transverse sliding rod 6 connects them. The lifting platform body 7 is fitted on the transverse sliding rod 6. By controlling its transverse movement and lifting, the position of the laser cutting head 8 can be flexibly adjusted to achieve precise cutting of the raw material. During the cutting process, the blower box 9 draws in air and blows it into the working area, blowing away the cutting debris. The debris enters through the air inlet 45 of the air inlet box 10, is intercepted by the internal interception net 49, and falls into the waste collection box 25. The air passes through the air outlet 50, the ventilation pipe 11, and the internal air pipe 47, and is blown out from the air outlet 48. Through the ventilation grooves 30 on the surface of the clamping block 21 and the clamping auxiliary plate 27, the surface of the raw material at the clamping position is cooled, reducing the impact of thermal stress. If the processing surface of the raw material needs to be adjusted, the small electric shaft 37 rotates to flip the sliding inclined block 38, the two auxiliary clamping components are reset, the side telescopic motor 17 drives the lifting plate 12 to rise and reload the raw material, the drive motor 14 causes the two meshing plates 16 to separate and lose their clamping of the raw material, the adjustment motor 40 drives the raw material to flip vertically and then place it back on the lifting plate 12, and the clamping steps are repeated to continue cutting and processing.

8. A method for machining, cutting, and fixing the valve body of a rotary ball valve, used in the machining, cutting, and fixing device for the rotary ball valve described in any one of claims 1-7, characterized in that, Includes the following steps: S1: Place the valve body material to be processed in the center of the lifting plate and close the sliding doors on both sides of the outer shell to isolate the external working environment from the internal processing and ensure processing accuracy. S2: Start the drive motor to drive the bidirectional screw to rotate. Through the meshing action, the two meshing plates move inward along the sliding groove. The two clamping blocks then approach each other to initially clamp the bottom surface of the raw material. At the same time, the sliding inclined block on one side of the clamping block contacts the side slider of the auxiliary clamping assembly. The small sliding rod slides on the surface of the side slider, pushing the clamping plate to pull the connecting spring closer. The two clamping auxiliary plates clamp the two sides of the raw material to form a stable clamping effect on four sides. S3: Controls the retraction of the four side telescopic motors, driving the lifting plate to descend and detach it from the bottom of the raw material, providing a stable processing environment for subsequent cutting operations; S4: By adjusting the carriage components through the control system, the lifting platform moves laterally on the horizontal sliding rod and simultaneously moves vertically up and down, adjusting the laser cutting head to the designated cutting position above the raw material for precise cutting operation; S5: During the cutting process, the fan inside the air blower box is activated to generate airflow that blows towards the cutting area, dispersing the debris and smoke generated during cutting and maintaining a clear view of the cutting area; the debris enters the air intake box through the air inlet on one side of the air intake box with the airflow, is intercepted by the internal interception net and falls into the waste collection box for storage. At the same time, the airflow passes through the air outlet, ventilation pipe, and internal air duct, and finally blows out from the air outlet to cool the side surface of the raw material at the clamping position and reduce the impact of thermal stress on the raw material; S6: When it is necessary to adjust the processing surface of the raw material, first control the small electric shaft to rotate through the control system, so that the sliding wedge is flipped and the two auxiliary clamping components are reset to make room for the flipping of the raw material. Then, control the four side telescopic motors to drive the lifting plate to rise and reload the raw material. Next, start the drive motor to separate the two meshing plates and lose the clamping of the raw material. Then, drive the adjusting motor to flip the raw material vertically. After flipping, place it back on the lifting plate. Finally, repeat step S2 to clamp and continue the subsequent cutting and processing procedures.
