Description

Technical Field

[0001] This invention relates to the field of valve body processing technology, specifically to an automatic flipping and feeding device for valve body processing. Background Technology

[0002] The valve body flange sealing surface refers to the sealing surface at the connection between the valve and the pipeline. Its function is to ensure that no leakage occurs at the connection between the valve and the pipeline, thereby guaranteeing the normal operation of the fluid system. The quality of the valve body flange sealing surface directly affects the service life and sealing performance of the valve.

[0003] During manufacturing and installation, the valve body flange sealing surface needs to undergo rigorous processing and testing to ensure that its dimensional accuracy and surface finish meet design requirements. Existing technologies for processing valve body flange sealing surfaces mainly have the following problems: 1. During precision machining of the valve body flange sealing surface, due to the special shape of the valve body, it is difficult to stably position it. Therefore, the valve body is prone to displacement during processing, leading to machining errors.

[0004] 2. The general finishing process requires fixing the sealing surfaces of the flanges at both ends of the valve body facing upwards before proceeding with the corresponding machining operations. This process usually requires manual assistance in loading and unloading materials and changing the position of the valve body flange sealing surfaces, resulting in low continuity of the machining process and affecting machining efficiency.

[0005] Therefore, in order to solve the problems of unstable valve body positioning and low processing continuity, the present invention provides an automatic flipping and feeding device for valve body processing. Summary of the Invention

[0015] In summary, the present invention has at least one of the following beneficial technical effects:

[0016] 1. This invention provides an automatic flipping and feeding device for valve body processing, mainly comprising a flipping and feeding unit and a processing positioning unit. The valve body is first clamped and positioned using a stabilizing clamping part. When the valve body is brought above the single-door fixing frame, the inner positioning part is activated to assist in positioning and stabilizing the bottom of the valve body. Simultaneously, the upper port structure of the telescopic positioning component not only supports the extended portion of the valve body that connects to the valve cover but also limits the valve body's position. Furthermore, under the stable clamping of the stabilizing clamping part, the valve body maintains a stable position during processing, preventing positional shifts that could lead to problems during processing. The process is designed to minimize errors. The arc-shaped limiting block and the limiting support frame work together to initially limit the valve body. The plate chain conveyor can continuously and intermittently transport materials. Each time a valve body to be processed moves to the initial processing position, it will stop intermittently for a certain period of time. During this process, the flipping feeding unit will automatically load and unload the materials. After processing one flange sealing surface of the valve body, the flipping feeding unit will rotate the valve body 180° so that the other flange sealing surface is facing upwards for processing. The entire process is continuous to achieve continuous processing of the valve body, which significantly improves the processing efficiency.

[0017] 2. The set stable clamping part drives the clamping assembly to work, so as to stably clamp the straight pipe sections at the top and bottom of the valve body. When the flange sealing surface needs to be changed, the flip plate can be driven to rotate 180° synchronously through the output shaft of the motor, which can quickly realize the position change of the flange sealing surface on the top and bottom of the valve body, indirectly improving the processing efficiency.

[0018] 3. The inner positioning part is set up, which drives multiple cylindrical sliders to move synchronously through the power component, so as to push the sliding bar to unfold outward, so that the fitting arc plate is tightly fitted to the inner wall of the valve body through hole, stabilizes and fixes the valve body, and ensures the stability of the valve body during processing.

Detailed Implementation

[0031] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Please see Figure 1 An automatic flipping and feeding device for valve body processing includes: a plate chain conveyor 1, a flipping and feeding unit 2, and a processing positioning unit 3. The plate chain conveyor 1 is provided with the flipping and feeding unit 2, and the processing positioning unit 3 is provided on the plate chain conveyor 1 and located to the right of the flipping and feeding unit 2.

[0033] Please see Figure 1 and Figure 4 The chain conveyor 1 has symmetrically fixedly installed limit support frames 11 on the left and right sides of the chain plate, and arc-shaped limit blocks 12 are symmetrically fixedly installed on the chain plate and between the limit support frames 11.

[0034] Please see Figure 2 and Figure 4The flipping feeding unit 2 includes a positioning track 21, an electric slide table 22, an electric telescopic component 23, a mounting block 24, a stabilizing clamping part 25, and a motor 26. The positioning track 21 is symmetrically fixed at both ends of the plate chain conveyor 1. The electric slide table 22 is slidably arranged on the positioning track 21. The electric telescopic component 23 is fixedly installed on the upper end of the electric slide table 22. The mounting block 24 is fixedly installed on the upper end of the electric telescopic component 23. The stabilizing clamping part 25 is rotatably connected between the mounting blocks 24. The motor 26 is fixedly installed at the front end of the mounting block 24 through a motor seat. The output shaft of the motor 26 is fixedly connected to the stabilizing clamping part 25.

[0035] First, the valve bodies that require processing of the flange sealing surfaces (inlet and outlet end faces of the valve body) are placed one by one on the chain plate of the plate chain conveyor 1 from the left side. The specific arrangement of the valve bodies is as follows: Figure 1 As shown, the specific operation method is as follows: the protruding part of the valve body connected to the valve cover is placed on the limiting support frame 11 with the right side (or left side) facing forward. The limiting support frame 11 provides stable support while positioning the valve body, ensuring the stability of the valve body when it is transported by the plate chain conveyor 1. The lower flange of the valve body is placed between the arc-shaped limiting blocks 12. The arc-shaped limiting blocks 12 and the limiting support frame 11 together play a preliminary limiting role for the valve body. Then, the plate chain conveyor 1 continuously and intermittently transports materials.

[0036] When the valve body is transported to the initial position of the stabilizing clamping part 25 at the material handling station, it stops. The two electric telescopic components 23 simultaneously move the stabilizing clamping part 25 downwards a certain distance, allowing it to position and clamp the valve body. After clamping, the electric telescopic components 23 push the mounting block 24 upwards a certain distance, and the stabilizing clamping part 25, holding the valve body, moves upwards to leave the chain plate. The electric slide 22 moves to the right on the positioning track 21, bringing the valve body directly above the processing positioning unit 3. At this point, the electric telescopic components 23 move the mounting block 24 downwards a certain distance, ensuring the valve body is stably positioned on the processing positioning unit 3, preventing movement during processing. After the upper flange sealing surface is finished, the electric telescopic components 23 push the mounting block 24 upwards again a certain distance, and the motor 26 rotates to drive the stabilizing clamping part. The holding part 25 is rotated 180° to interchange the positions of the lower flange sealing surface and the upper processed flange sealing surface. Then, the electric telescopic part 23 moves the mounting block 24 downward a certain distance to reposition the valve body on the processing positioning unit 3. After processing, the electric telescopic part 23 pushes the mounting block 24 upward a certain distance so that the holding part 25 holds the valve body away from the processing positioning unit 3. The electric slide 22 moves to the left on the positioning track 21 to return to the initial position. The electric telescopic part 23 moves the mounting block 24 downward to place the valve body on the upper end of the chain plate. At this time, the protruding part of the valve body connected to the valve cover is facing the left (or right) and resting on the limiting support frame 11. Finally, the processed valve body is transported to the right by the plate chain conveyor 1 for easy removal. The whole process is carried out continuously to realize the continuous processing of the valve body.

[0037] Please see Figure 2 and Figure 7The stabilizing clamping part 25 includes a flip plate 251, a rectangular through hole 252, positioning side plates 253, a clamping assembly 254, and a driving assembly 255. The flip plate 251 is rotatably connected to the mounting blocks 24. The flip plate 251 has a rectangular through hole 252 in the middle. Positioning side plates 253 are symmetrically fixedly installed at both ends of the flip plate 251 about the rectangular through hole 252. A clamping assembly 254 is arranged between the front and rear opposite positioning side plates 253. The driving assembly 255 is symmetrically arranged on the flip plate 251. The driving assembly 255 and the clamping assembly 254 are connected. The two parts mesh with each other; when the stable clamping part 25 is in the initial working position, the electric telescopic part 23 moves the mounting block 24 downward, so that the flipping plate 251 moves downward. The rectangular through hole 252 will pass through the valve body. When it moves to the clamping position, the drive component 255 drives the clamping component 254 to work, so as to achieve stable clamping of the straight pipe sections at the upper and lower parts of the valve body; when the flange sealing surface needs to be changed at the processing positioning unit 3, the motor 26 can be rotated to drive the flipping plate 251 to rotate synchronously by 180°, so that the upper and lower flanges of the valve body can be changed.

[0038] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5The clamping assembly 254 includes a limiting slide rod 2541, a limiting slide groove 2542, a moving plate 2543, an extending support rod 2544, a mating clamp 2545, a rotating threaded rod 2546, and a mating helical gear 2547. The limiting slide rod 2541 is symmetrically fixed between the front and rear opposing positioning side plates 253. The limiting slide groove 2542 is symmetrically formed on the flip plate 251 between the front and rear opposing positioning side plates 253. The moving plate 2543 is slidably mounted on the limiting slide groove 2542, and the moving plate 2543 slides in cooperation with the limiting slide rod 2541. An extending support rod 2544 is fixedly mounted at the middle of the end of the moving plate 2543 away from the flip plate 251. A mating clamp 2545 is fixedly mounted on the extending support rod 2544. The moving plate 2543 rotates at the middle of the end near the positioning side plate 253. A rotating threaded rod 2546 is movably connected to the positioning side plate 253. A mating helical gear 2547 is rotatably connected to the end of the positioning side plate 253 away from the moving plate 2543. The mating helical gear 2547 is threadedly connected to the rotating threaded rod 2546. The mating helical gear 2547 is driven to rotate by the drive assembly 255. The rotation of the mating helical gear 2547 can drive the rotating threaded rod 2546 at the corresponding position to move back and forth. The front and rear opposing rotating threaded rods 2546 will move closer to each other to push the moving plate 2543 to move stably in a straight line under the limitation of the limiting slide groove 2542 and the limiting slide rod 2541, so that the front and rear opposing mating clamps 2545 can fix and clamp the valve body. The drive assembly 255 drives the mating helical gear 2547 to rotate in the opposite direction, which can realize the release of the valve body.

[0039] Please see Figure 5 , Figure 7 and Figure 8The drive assembly 255 includes a rotating connecting rod 2551, a driving helical gear 2552, a driven gear 2553, a connecting shaft 2554, a driving gear 2555, and a motor 2556. The rotating connecting rod 2551 is symmetrically rotatably connected to the tilting plate 251. The driving helical gear 2552 is symmetrically fixedly mounted on the rotating connecting rod 2551, meshing with a nearby mating helical gear 2547. The driven gear 2553 is fixedly mounted in the middle of the rotating connecting rod 2551. The connecting shaft 2554 is rotatably connected to the tilting plate 251 and located to the right of the driven gear 2553. The driving gear 2555 is fixedly mounted on the connecting shaft 2554. 555, a second motor 2556 is fixedly installed on the upper end of the flip plate 251. The output shaft of the second motor 2556 is fixedly connected to the drive gear 2555. The second motor 2556 drives the connecting shaft 2554 to rotate. The connecting shaft 2554 drives the drive gear 2555 to rotate synchronously. The drive gear 2555 drives the driven gear 2553 to rotate rapidly to realize the rotation of the rotating connecting rod 2551. The rotating connecting rod 2551 drives the drive helical gear 2552 to rotate synchronously. The drive helical gear 2552 at the corresponding position will drive the meshing helical gear 2547 to rotate, ultimately realizing the clamping or releasing of the valve body by the clamping fixture 2545.

[0040] Please see Figure 2 , Figure 3 and Figure 6 The processing positioning unit 3 includes a single-door fixing frame 31, a telescopic positioning component 32, an inner positioning part 33, and an arc-shaped limiting block 34. A single-door fixing frame 31 is fixedly installed on the plate chain conveyor 1 and located to the right of the flipping feeding unit 2. Telescopic positioning components 32 are symmetrically fixedly installed on the upper horizontal plate of the single-door fixing frame 31. An inner positioning part 33 is fixedly installed on the upper horizontal plate of the single-door fixing frame 31 and located between the telescopic positioning components 32. Arc-shaped limiting blocks 34 are uniformly fixedly installed on the upper horizontal plate of the single-door fixing frame 31 and circumferentially around the inner positioning part 33. When the valve body is brought directly above the inner positioning part 33 by the stabilizing clamping part 25, the mounting block 24 is moved downwards by the electric telescopic component 23, i.e., the stabilizing clamping part 24 is engaged. The holding part 25 clamps the valve body and moves it downward, so that the lower flange of the valve body is positioned between the arc-shaped limiting blocks 34. At this time, the inner positioning part 33 is located in the lower through hole of the valve body. Activating the inner positioning part 33 can assist in positioning and stabilizing the bottom of the valve body. At the same time, the upper port structure of the telescopic positioning part 32 can not only cooperate to support the protruding part of the valve body that is connected to the valve cover, but also limit the valve body. Under the stable clamping of the holding part 25, the valve body can maintain a stable position during processing, avoiding processing errors caused by position displacement. When the valve body needs to be flipped, the telescopic positioning part will retract a certain distance downward, which facilitates the flipping operation of the valve body by the flipping feeding unit 2.

[0041] Please see Figure 3 and Figure 6 The inner positioning part 33 includes a bottom frustum 331, a mating groove 332, a sliding bar 333, a fitting arc plate 334, a cylindrical slider 335, and a power assembly 336. The bottom frustum 331 is fixedly installed on the upper end of the horizontal plate of the single-door fixing frame 31, located between the telescopic positioning members 32. The mating groove 332 is evenly distributed circumferentially on the upper end of the bottom frustum 331. A sliding bar 333 is slidably mounted on the mating groove 332, and a fitting arc plate 334 is fixedly installed on the sliding bar 333. A cylindrical slider 335 is fixedly installed at the upper end of the strip 333 and near the center of the bottom truncated cone 331. A power assembly 336 is provided on the bottom truncated cone 331. The power assembly 336 and the cylindrical slider 335 slide together. The power assembly 336 drives multiple cylindrical sliders 335 to move synchronously, so as to push the sliding strip 333 outward, so that the fitting arc plate 334 fits tightly against the inner wall of the valve body through hole, thereby stabilizing and fixing the valve body and keeping the valve body stable during processing.

[0042] Please see Figure 2 and Figure 6 The power assembly 336 includes a motor 3361, a rotating disk 3362, and an arc-shaped slot 3363. The motor 3361 is fixedly installed on the upper end of the horizontal plate of the single-door fixing frame 31 and below the bottom truncated cone 331. The output shaft of the motor 3361 is fixedly connected to the rotating disk 3362. The upper end of the rotating disk 3362 is evenly provided with arc-shaped slots 3363 in the circumferential direction. The arc-shaped slots 3363 are connected to the corresponding cylindrical sliders 335 in a sliding fit. The rotating disk 3362 is driven to rotate by the motor 3361. The rotation of the rotating disk 3362 will drive the cylindrical sliders 335 that are fitted in the arc-shaped slots 3363 to move, so that the cylindrical sliders 335 move outward synchronously. The reverse rotation of the motor 3361 can realize the synchronous inward movement of the cylindrical sliders 335 to retract and fix them to the inner side of the valve body.

[0043] The working principle of this invention is as follows: When the valve body is transported to the initial position of the stabilizing clamping part 25 at the material-receiving station, it stops. The stabilizing clamping part 25 can position and clamp the valve body. The electric slide 22 moves to the right on the positioning track 21, so that the valve body is brought to the position directly above the processing positioning unit 3 and stops. The valve body can be stably positioned on the processing positioning unit 3 to ensure that the valve body will not move during processing. After the upper flange sealing surface is processed, the motor 26 drives the stabilizing clamping part 25 to rotate 180°, so that the lower flange sealing surface and the upper processed flange sealing surface are interchanged. Then the valve body is stabilized and positioned again on the processing positioning unit 3. After processing is completed, the stabilizing clamping part 25 clamps the valve body and leaves the processing positioning unit 3. The electric slide 22 moves to the left on the positioning track 21 to return to the initial position and places the valve body on the upper end of the chain plate. Finally, the processed valve body is transported to the right by the plate chain conveyor 1 for easy removal. The whole process is carried out continuously to realize the continuous processing of the valve body.
