Description

Technical Field

[0001] This invention relates to the field of valve processing technology, specifically to a valve coaxiality machining correction structure. Background Technology

[0002] Valves, as core control components in fluid transport systems, are widely used in various industrial fields such as petrochemicals, power, water treatment, and aerospace. The coaxiality of a valve mainly refers to the degree of alignment of the axes of key mating parts such as the shaft holes at both ends of the valve body, the valve stem and valve seat, and the screw and drive shaft. Its precision control directly affects the smoothness of valve opening and closing, the fit of the sealing pairs, and the compatibility and operational reliability of subsequent assembly.

[0003] Currently, the industry mainly relies on two methods to control valve coaxiality: one is to rely on high-precision machining equipment and online testing equipment to reduce coaxiality error by improving machining and testing accuracy; the other is to use traditional calibration methods, such as dial indicator calibration and V-block positioning calibration.

[0004] However, existing coaxiality detection and correction structures have many drawbacks. Dedicated correction devices are complex in structure and lack versatility, only suitable for specific valve models or specifications, and cannot meet diverse processing needs. Some correction schemes can only achieve offline correction after processing and cannot be adjusted in real time. Once coaxiality deviation is found, re-clamping and processing are required, affecting production efficiency and increasing costs. To address these issues, this invention proposes a valve coaxiality processing correction structure to solve the above-mentioned technical problems. Summary of the Invention

[0016] In summary, the technical effects and advantages of this invention are as follows: In this invention, an L-shaped mounting cavity is assembled on the top left side of the operating table. The front end of the L-shaped mounting cavity has two sets of opposing side support cavities integrally formed. Each of the two sets of side support cavities has a front side frame cavity integrally formed on its opposite side. A telescopic assembly extending into the inner side of the side support cavity is installed within the front side frame cavity. A limit plate is fixedly installed on the telescopic assembly extending into the inner wall of the side support cavity. The telescopic assembly can achieve telescopic extension and 360° horizontal rotation through a rotating rod and other structures. By pushing the limit plate with the telescopic assembly, the valve is stably clamped, ensuring clamping firmness and preventing valve loosening or displacement during processing. It also allows for flexible horizontal rotation according to the processing shape, eliminating the need for repeated disassembly and reassembly of the valve, significantly reducing the number of clamping operations, lowering positioning errors, and improving processing flexibility to adapt to different angle processing requirements, thus significantly improving the convenience and efficiency of valve processing.

[0017] In this invention, a rear support cavity is integrally formed at a position perpendicular to the two sets of front support cavities within an L-shaped mounting cavity. A pusher plate is mounted inside the L-shaped mounting cavity at a position parallel to the rear of the limiting plate. A pushing assembly that acts on the pusher plate is provided inside the rear support cavity. When the valve is positioned in the middle of the two sets of side support cavities, the valve can be precisely centered through the synergistic action of the two sets of pushers, ensuring that the valve's central axis coincides with the machining datum line. This provides a precise positioning basis for subsequent coaxiality machining correction, avoids machining deviations caused by valve offset, and thus improves the axial coincidence of key valve mating parts. This ensures the smoothness of valve opening and closing, the fit of the sealing pair, and the compatibility and operational reliability of subsequent assembly, reducing the product scrap rate caused by coaxiality deviations.

[0018] In this invention, by setting a movable cavity, a movable seat, and a mounting seat on the right side of the operating table perpendicular to the L-shaped mounting cavity, integrated processing, positioning, and assembly are achieved, optimizing the overall processing flow. The movable cavity can install the remaining assembly parts of the valve, facilitating subsequent processing and assembly operations, reducing the steps of workpiece transfer, and lowering the risk of collision damage during transfer. The infrared ray mechanism mounted on the movable seat can accurately irradiate and transmit signals to the valve to be drilled, held in the L-shaped mounting cavity, achieving precise positioning of the processing position, avoiding drilling deviation, and further improving processing accuracy. The mounting seat can subsequently install robotic arms and other processing parts, expanding the processing functions of the device and adapting to diverse valve processing needs. In use, the infrared ray mechanism accurately positions the valve held in the L-shaped mounting cavity, and the movable cavity or mounting seat drives the subsequent workpieces to perform drilling or assembly operations, achieving coordinated positioning, processing, and assembly.

[0021] 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.

[0022] refer to Figures 1-10 The valve coaxiality machining correction structure shown includes an operating table 1 and an L-shaped mounting cavity 2 located on the top of the operating table 1. A specific embodiment is shown below: Example 1

[0023] This embodiment includes the positional distribution and collaborative use of the L-shaped mounting cavity 2, movable cavity 7, mounting base 9, and movable base 8 on the top of the operating table 1. All four are arranged sequentially at intervals along the width direction of the operating table 1, forming an integrated layout structure for processing, positioning, and assembly, which is suitable for the entire process requirements of valve coaxiality processing.

[0024] In terms of position, the L-shaped mounting cavity 2 is fixed to the top left side of the operating table 1, serving as the core clamping and positioning area for the valve. Its overall structure is an inverted L-shape, with two sets of opposing side support cavities 202 integrally formed on the side wall perpendicular to the top of the operating table 1. These cavities, in conjunction with the limiting plate 4, clamp and fix the valve. The movable cavity 7, mounting seat 9, and movable seat 8 are all mounted on the right side of the operating table 1. Along the width of the operating table 1, from left to right, they are the movable cavity 7, mounting seat 9, and movable seat 8, respectively mounted on electric slide rail 103, electric slide rail 2 104, and electric slide rail 3 105. They can slide along the length of their corresponding electric slide rails, allowing for flexible position adjustment. All three correspond to the clamping area of ​​the L-shaped mounting cavity 2, ensuring precise alignment of processing and positioning actions. The movable cavity 7 is used to install the remaining assembly parts of the valve, providing support for subsequent processing and assembly operations. The mounting seat 9 can be used to install robotic arms or other processing parts according to processing requirements, expanding the processing function of the device. The movable seat 8 is used to install the infrared ray mechanism 802, achieving precise positioning of the processing position.

[0025] During operation, the valve to be processed is first placed between the two sets of side support chambers 202 of the L-shaped mounting cavity 2. The telescopic components within the side support chambers 202 push the limiting plate 4 to clamp and center the valve. Then, according to processing requirements, the position of the moving cavity 7 is adjusted via electric slide rail 103 to precisely align the valve assembly workpiece mounted on the moving cavity 7 with the valve clamped in the L-shaped mounting cavity 2, facilitating subsequent assembly operations. The position of the mounting seat 9 is adjusted via electric slide rail 204 to align the robotic arm and other processing workpieces on the mounting seat 9 with the processing area of ​​the valve, preparing for drilling, grinding, and other processing operations. The position of the movable seat 8 is adjusted via electric slide rail 305 to align the infrared ray mechanism 802 on the movable seat 8 with the processing area of ​​the valve, achieving precise positioning of the processing position. These three components work together to flexibly adjust the position according to different processing steps of the valve, eliminating the need for repeated valve disassembly, effectively improving processing efficiency while ensuring processing accuracy and avoiding coaxiality errors caused by positional offsets.

[0026] Example 2 This embodiment includes the positional distribution of the push plate 3, the limiting plate 4, and the flower-shaped baffle 1001 inside the L-shaped mounting cavity 2, as well as the synergistic effect of the three in the valve clamping and positioning process, to ensure that the valve is firmly clamped and accurately positioned, to avoid deviation during processing, and to ensure coaxiality processing accuracy.

[0027] In terms of position, there are two sets of limiting plates 4, which are fixedly connected to the end walls of the hollow rods 403 inside the two sets of side support cavities 202. The two sets of limiting plates 4 are arranged opposite each other and are located in the front end area of ​​the L-shaped mounting cavity 2. Multiple sets of anti-wear blocks 402 are evenly distributed on the side away from the hollow rods 403 for direct contact with the valve to clamp and fix the valve. The push plate 3 is assembled inside the L-shaped mounting cavity 2, parallel to the rear side of the limiting plates 4. The side facing the inner wall of the L-shaped mounting cavity 2 is movably fitted with the inner wall of the L-shaped mounting cavity 2, and the side away from the inner wall of the L-shaped mounting cavity 2 is fixedly connected to the moving plate 301. The moving plate 301 is slidably assembled on the inner wall of the rear side support cavity 201 and is connected through a horizontal support rod 303. It can slide along the length of the horizontal support rod 303, thereby driving the push plate 3 to move synchronously. The flower-shaped baffle 1001 is fixedly connected to the telescopic end of the hydraulic telescopic rod 4 10. The hydraulic telescopic rod 4 10 is installed through the center of the side of the L-shaped mounting cavity 2 away from the side support cavity 202, and is assembled in accordance with the circular groove 206 opened on the L-shaped mounting cavity 2. The flower-shaped baffle 1001 is located inside the L-shaped mounting cavity 2 and is arranged opposite to the limiting plate 4 to support the rear end of the valve assembly clamped on the limiting plate 4.

[0028] During use, when the valve is placed between the two sets of side support chambers 202, the sliding plug 406 is first moved by the hydraulic component 405 on the outside of the telescopic chamber 404, which drives the hollow rod 403 to extend and retract, thereby pushing the two sets of limiting plates 4 closer together to clamp the valve. The anti-wear block 402 can prevent wear on the valve surface during clamping and at the same time enhance the clamping friction to prevent the valve from loosening. Since the valve is easily deviated from the center position of the L-shaped mounting chamber 2 when it is placed in the middle position of the two sets of side support chambers 202, the moving plate 301 is driven to slide along the horizontal support rod 303 by the pushing component in the rear frame chamber 201, which drives the push plate 3 to move synchronously. The two sets of push plates 3 work together to accurately push the valve to the center position of the L-shaped mounting chamber 2, ensuring that the central axis of the valve coincides with the machining datum line, providing accurate positioning for coaxiality machining. The flower-shaped baffle 1001 plays a supporting role during valve clamping, preventing the rear end of the valve assembly from shifting and ensuring the stability of valve clamping.

[0029] When the valve needs to be rotated to adapt to different processing angles, motor 401 drives the extended rotating rod 407 to rotate. Through the cooperation of the retaining strip 408 and the slide groove, the hollow rod 403 is rotated, which in turn drives the limiting plate 4 and the valve to rotate synchronously. At this time, the hydraulic telescopic rod 10 will drive the flower-shaped baffle 1001 to retract synchronously to avoid the flower-shaped baffle 1001 from obstructing the rotation of the valve. After rotating to the appropriate angle, the hydraulic telescopic rod 10 pushes the flower-shaped baffle 1001 to reset again, supporting the rear end of the valve again, ensuring that the valve remains stable during the processing and avoiding coaxiality errors caused by rotational offset.

[0030] Example 3 This embodiment includes the positional distribution and usage of the placement plate 5 and the movable plate 6 on the movable cavity 7. The two work together to place and position the remaining assembly parts of the valve, which facilitates subsequent docking and assembly with the valve clamped on the L-shaped mounting cavity 2, thereby improving assembly efficiency and assembly accuracy.

[0031] In terms of position, the placement plate 5 is fixedly connected to the extension end of the hydraulic telescopic rod 703, which is fixedly connected to the side of the sliding support plate 704 away from the moving cavity 7. The sliding support plate 704 slides against the side of the maintenance plate 702 away from the moving cavity 7. The maintenance plate 702 is detachably connected to the side of the moving cavity 7 away from the electric slide rail 103. The maintenance plate 702 has an opening along its length to accommodate the sliding of the sliding support plate 704. The side of the sliding support plate 704 facing the maintenance plate 702 passes through the opening and extends into the moving cavity 7, where it is rotatably connected to the rotating shaft rod 701. It can slide along the opening under the drive of the rotating shaft rod 701, thereby driving the hydraulic telescopic rod 703 and the placement plate 5 to move synchronously.

[0032] The movable plate 6 is slidably mounted on the slide rail 501, which is fixedly connected to the inner wall of the placement plate 5 along its length. A corresponding plate 601 is fixedly connected to the top end wall of the slide rail 501 away from the placement plate 5. The movable plate 6 is arranged perpendicular to the corresponding plate 601, and a sliding frame 605 is fixedly connected to its bottom end facing the inner wall of the placement plate 5. An auxiliary strip 503, adapted to the sliding of the sliding frame 605, is fixedly connected to the placement plate 5 at the position corresponding to the sliding frame 605. The sliding frame 605 and the auxiliary strip 503 cooperate to enhance the stability of the sliding of the movable plate 6. In addition, a sealing plate 502 is detachably connected to the side of the placement plate 5 away from the movable plate 6. A clamping frame 604 is fixedly connected to the side of the sealing plate 502 away from the movable plate 6. A hydraulic telescopic rod 603 is fixedly clamped on the clamping frame 604. The extension end of the hydraulic telescopic rod 603 is fixedly connected to the movable plate 6 through the connecting frame 602 for driving the movable plate 6 to slide.

[0033] During use, the remaining assembly parts of the valve are first placed on the placement plate 5. According to the size of the workpiece and the assembly requirements, the rotating shaft 701 is driven to rotate by the motor 3 705, which drives the sliding support plate 704 to slide along the opening on the inspection plate 3 702. Then, the position of the hydraulic telescopic rod 2 703 and the placement plate 5 are adjusted so that the workpiece on the placement plate 5 is precisely aligned with the valve clamped on the L-shaped mounting cavity 2.

[0034] Then, the hydraulic telescopic rod 603 is activated. The extended end of the hydraulic telescopic rod 603 pushes the connecting frame 602 to move, causing the movable plate 6 to slide along the slide rail 501. The sliding frame 605 slides synchronously along the auxiliary strip 503, ensuring that the movable plate 6 moves smoothly. The movable plate 6 and the corresponding plate 601 work together to clamp and fix the assembled workpiece on the placement plate 5, preventing the workpiece from shifting during assembly. When it is necessary to adjust the angle of the workpiece, the height of the placement plate 5 can be adjusted through the hydraulic telescopic rod 703 to ensure precise alignment between the workpiece and the valve assembly part, facilitating smooth subsequent assembly operations.

[0035] Example 4 This embodiment includes the positional distribution and usage of each component on the movable seat 8. The core is to achieve precise positioning of the valve processing position through the infrared ray mechanism 802, providing precise guidance for valve coaxiality processing, avoiding processing deviations, and improving processing accuracy.

[0036] In terms of position, the movable seat 8 is slidably mounted on the side of the electric slide rail 3 105 opposite to the operating table 1, and can slide along the length of the electric slide rail 3 105 to achieve flexible position adjustment and adapt to the processing needs of different positions. The hydraulic telescopic rod 3 801 is fixedly connected to the top of the movable seat 8, and its extension end is fixedly connected to the infrared ray mechanism 802. The irradiation end of the infrared ray mechanism 802 corresponds to the valve clamped on the L-shaped mounting cavity 2, and its height can be adjusted under the drive of the hydraulic telescopic rod 3 801 to ensure that the infrared rays can accurately irradiate the processing area of ​​the valve. The infrared ray mechanism 802 is used to emit infrared rays to accurately irradiate and transmit signals to the processing part of the valve, providing accurate positioning guidance for subsequent processing operations.

[0037] During operation, after the valve on the L-shaped mounting cavity 2 is clamped and centered, the horizontal position of the movable seat 8 is adjusted via the electric slide rail 3105 according to the valve's processing requirements, allowing the infrared ray mechanism 802 to irradiate the area of ​​the valve to be processed. Then, the hydraulic telescopic rod 3801 is activated, raising and lowering its extension end to adjust the height of the infrared ray mechanism 802, ensuring that the infrared rays accurately irradiate the part of the valve to be processed, achieving precise positioning of the processing location. After positioning, the infrared ray mechanism 802 continuously emits infrared rays, providing positioning guidance for the robotic arm and other workpieces on the mounting base 9, ensuring that the robotic arm can accurately align with the processing area for drilling, grinding, and other processing operations.

[0038] Example 5 This embodiment includes the positional distribution and usage of the push plate 3, moving plate 301, left triangular block 302, horizontal support rod 303, spring 305, fixed plate 306, right triangular block 307, rotating shaft 308, sliding block 309, clamping plate 310 and motor 311. The valve is pushed in the center through inclined plane transmission, ensuring the coaxiality correction and positioning accuracy.

[0039] In terms of position, the push plate 3 is fixedly connected to the side of the movable plate 301 facing the inner wall of the L-shaped mounting cavity 2. The movable plate 301 is slidably sleeved on the outer periphery of the horizontal support rod 303 and can slide along the rod. One end of the horizontal support rod 303 near the inner wall of the L-shaped mounting cavity 2 is fixed to the inner wall of the cavity through the fixing block 304, and the other end away from the cavity is fixedly connected to the fixing plate 306. The upper and lower ends of the fixing plate 306 are fixed to the inner wall of the rear side frame cavity 201. The spring 305 is sleeved on the outside of the horizontal support rod 303, and its two ends are movably fitted with the fixing block 304 and the movable plate 301, respectively. The left triangular block 302 is fixed on the side of the movable plate 301 facing the fixing plate 306, and the right triangular block 307 is fixed at the corresponding position on the fixing plate 306. The two are arranged with their inclined surfaces facing each other. The sliding block 309 slides and fits between the left triangular block 302 and the right triangular block 307. The top and bottom ends are integrally formed with a card plate 310. The center of the sliding block 309 is rotatably connected to the rotating shaft rod 308. The rotating shaft rod 308 is driven to rotate by the motor 311 on the outside of the rear frame cavity 201.

[0040] During operation, motor 311 drives shaft 308 to rotate, causing sliding block 309 to move along the inclined plane of the left and right triangular blocks. The inclined plane presses and pushes the left triangular block 302 and the moving plate 301 forward along the horizontal support rod 303, thereby driving the pusher plate 3 to move towards the valve, accurately pushing the valve to the center position and completing the coaxiality correction and positioning. After processing, motor 311 reverses, sliding block 309 exits the pressing position, and spring 305 pushes the moving plate 301 and the pusher plate 3 back to their original position along the horizontal support rod 303, releasing the valve. This structure provides smooth transmission and accurate positioning, effectively preventing valve deviation and improving the coaxiality accuracy of the processing.

[0041] Working principle of this invention: Before processing, the valve to be processed is placed between the two sets of side support chambers 202 of the L-shaped mounting cavity 2. The sliding plug 406 is driven by the hydraulic component 405 in the side support chamber 202, which drives the hollow rod 403 to extend and retract, pushing the two sets of limiting plates 4 closer together to achieve valve clamping. The anti-wear block 402 can prevent wear on the valve surface and enhance clamping stability. At the same time, the pushing component in the rear frame cavity 201 drives the moving plate 301 to slide along the horizontal support rod 303, which drives the pushing plate 3 to push the valve to the center of the L-shaped mounting cavity 2, ensuring that the valve axis coincides with the processing reference line. The hydraulic telescopic rod 10 pushes the flower-shaped baffle 1001 to support the rear end of the valve, further improving clamping stability.

[0042] During processing, the movable seat 8 slides along the electric slide rail 105, and the hydraulic telescopic rod 801 adjusts the height of the infrared ray mechanism 802 to precisely align it with the valve area to be processed, emitting infrared rays to provide positioning guidance for processing. The mounting seat 9 moves along the electric slide rail 104, and the robotic arm and other processing parts mounted on it align with the processing area according to the infrared positioning signal to complete operations such as drilling and grinding.

[0043] During the assembly stage, the movable cavity 7 slides along the electric slide rail 103 to the corresponding position. The motor 3 705 drives the rotating shaft 2 701, which in turn moves the sliding support plate 704, the hydraulic telescopic rod 2 703, and the placement plate 5, so that the valve assembly workpiece on the placement plate 5 is precisely aligned with the valve on the L-shaped mounting cavity 2. Subsequently, the hydraulic telescopic rod 1 603 drives the movable plate 6 to slide along the slide rail 501, which cooperates with the corresponding plate 601 to clamp the workpiece. The hydraulic telescopic rod 2 703 adjusts the height of the placement plate 5 to achieve precise assembly.

[0044] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.
