Description

Technical Field

[0001] The invention relates to the technical field of flange processing, and in particular to a polishing device for flange surface processing and a use method thereof. Background Art

[0002] Flange, also called flange flange or flange. Flange is a part that connects shafts to each other and is used to connect pipe ends. It is also used as a flange on the inlet and outlet of equipment to connect two devices, such as reducer flange.

[0003] For example, a side polishing lathe for flange production disclosed in publication number CN222200041U includes a device body, a workbench is arranged on the surface of the device body, a support leg is welded to the bottom of the workbench, an anti-sliding block is welded to the bottom of the support leg, a grinding mechanism is fixedly installed on the left side of the surface of the workbench, and a flange fixing mechanism is fixedly installed on the right side of the surface of the workbench. The utility model fixes the flange by means of a fixing plate with bolts and hinge holes, so as to ensure that the flange will not fall off the flange mounting seat during grinding.

[0004] However, in the prior art, if the flange is placed at an unreasonable angle or position, its edge will be blocked by other workpieces or equipment components, resulting in some areas being unable to fully receive polishing. This situation can easily lead to uneven polishing, causing some areas to remain rough, while other areas are affected by over-polishing due to repeated polishing. In addition, when the angle adjustment freedom of the polishing equipment is low, the operator cannot flexibly adjust the polishing angle according to the specific conditions of the flange surface, further aggravating the problem of uneven polishing. Due to uneven force and wear during the polishing process, the sealing surface of the flange will have slight ups and downs, affecting its overall flatness. Once irregular bumps appear on the flange surface, it will not be able to fully fit with the gasket or docking flange, and the sealing performance will decrease accordingly. In high temperature, high pressure or corrosive medium environments, this poor sealing problem will be more serious, increasing the risk of medium leakage, which will not only affect the operating efficiency of the equipment, but also lead to safety hazards and increased maintenance costs. Summary of the invention

[0016] A method for using a polishing device for flange surface processing comprises the following steps:

[0017] Step 1: Fix the flange by placing the flange in the first support clamp, clamping the flange with the hinged second support clamp, and then locking the flange with the locking block to complete the fixing of the flange;

[0018] Step 2: Adjust the position of the grinding mechanism. The first cylinder pushes the fixed block to move, driving the movable frame and the top grinding mechanism to change their positions. The second guide block slides on the second slide rail to guide, ensuring stable movement and accurately adjusting the position of the polishing wheel.

[0019] Step 3: Adjust the angle and position of the polishing wheel. Turn the self-locking knob to drive the second rotating frame to rotate, change the angle of the polishing wheel, and the rotation of the rotating frame drives the first indicator rod and the gear ring to move, thereby indirectly changing the position of the polishing wheel.

[0020] Step 4: Change the position of the flange to be polished. The first driving motor drives the rotating rod to rotate, and the worm sleeve and the special-shaped worm gear drive the movable frame to move, thereby changing the position of the flange to be polished.

[0021] Step 5: Adjust the position of the inner flange of the fixture. The second cylinder pushes the first guide block to move, driving the rack to rotate the first gear, so that the two first guide blocks and the first slide rail move in opposite directions synchronously. The rotating column drives the first rotating frame to move, changing the position of the inner flange of the fixture.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. In the present invention, the rotation of the second rotating frame is controlled by a self-locking knob to achieve angle adjustment of the polishing wheel and ensure uniform polishing of the flange surface. During the rotation process, the second rotating frame drives the second indicator rod to rotate synchronously, and the stable rotation of the polishing wheel is ensured by the gear transmission system. The meshing design of the gear ring ensures the continuous transmission of power, making the polishing process smoother. At the same time, the second indicator rod cooperates with the first angle disk to provide an intuitive angle display, which is convenient for the operator to accurately adjust the polishing wheel angle to meet the needs of different workpieces. In addition, the interaction between the first indicator rod and the second angle disk makes the polishing angle adjustment more intuitive and controllable, improves the processing accuracy and consistency, and the overall design improves the polishing effect and production efficiency, ensuring stable and reliable product quality.

[0024] 2. In the present invention, the second cylinder drives the first guide block to move, thereby realizing synchronous pushing of the rack and making the two first guide blocks slide in opposite directions, thereby ensuring their limiting effect relative to the first slide rail and maintaining the stability of the movement. The rack drives the first gear to rotate, thereby affecting the other rack to realize bidirectional synchronous movement. The spacing of the threaded rod further limits the activity range of the first guide block to prevent offset and improve structural stability. At the same time, the rotation range of the first gear is controlled to avoid instability caused by excessive rotation. When the first gear drives the rotating column to rotate, its angle can be finely adjusted by the action of the threaded rod or the second cylinder, which finally affects the movement of the first rotating frame and accurately adjusts the internal flange position of the fixture. This design ensures that the fixture can flexibly adapt to different processing requirements, improves processing accuracy and system controllability, and enables the operator to adjust the angle according to needs to ensure the accuracy and stability of each processing.

[0025] 3. In the present invention, the first driving motor drives the rotating rod and the worm sleeve to rotate, and then acts on the special-shaped worm wheel to make it move in a specific direction. The movement of the special-shaped worm wheel further drives the movable frame to move, and the top clamp is adjusted synchronously, so as to achieve precise positioning of the flange to be polished and ensure its ideal angle and position during the processing. At the same time, the slider slides along the slide track, which not only guides the movement of the movable frame, but also effectively limits its active angle to prevent excessive deviation, thereby ensuring the accuracy and stability of the flange positioning. This limiting mechanism is crucial to avoiding processing errors and helps to improve the processing quality of the flange. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described 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 creative work are within the scope of protection of the present invention.

[0038] Example 1: Reference Figure 1 - Figure 5 As shown: A polishing device for flange surface processing, comprising a first bottom plate 1 and a movable frame 4 slidably mounted on the top thereof, a rotating mechanism 3 is mounted on the top of the first bottom plate 1, a movable mechanism 2 is mounted on the top of the rotating mechanism 3, a fixture 6 is mounted on the top of the movable mechanism 2, the fixture 6 is used to fix the flange to be polished, the rotating mechanism 3 is used to change the horizontal direction of the flange in the fixture 6, the movable mechanism 2 is used to change the vertical angle of the flange in the fixture 6, and a grinding mechanism 5 is mounted on the top of the movable frame 4;

[0039] The grinding mechanism 5 includes a mounting plate 51, a first angle plate 52 is fixedly connected to the top of the mounting plate 51, and a rotating frame 53 is rotatably connected to the center of the top of the mounting plate 51, a mounting shell 54 is fixedly connected to the top of the rotating frame 53, a connecting frame 551 is rotatably connected to the side wall of the mounting shell 54, a gear ring 55 is fixedly connected to the outer surface of the connecting frame 551, a fixed frame 58 is fixedly connected to the side wall of the bottom end of the rotating frame 53, a second rotating frame 57 is rotatably connected to the inner side of the fixed frame 58, an active rod 561 is rotatably connected to the middle part of the second rotating frame 57, one end of the active rod 561 is fixedly connected to the second gear 56, the second gear 56 is meshed with the gear ring 55, a second angle plate 581 is fixedly connected to the side wall of the fixed frame 58, a linkage rod 574 is fixedly connected to the side wall of the second rotating frame 57, one end of the linkage rod 574 passes through the fixed frame 58, and one end of the linkage rod 574 is fixedly connected to the second indicating rod 571.

[0040] A second drive motor 541 is installed on the inner side of the mounting shell 54. The output end of the second drive motor 541 is fixedly connected to the connecting frame 551. One end of the active rod 561 is fixedly connected to the polishing wheel 572. One end of the fixed frame 58 is rotatably connected to a self-locking knob 573. One end of the self-locking knob 573 is fixedly connected to the second rotating frame 57.

[0041] In this embodiment, during the polishing process, the self-locking knob 573 can be screwed to drive the rotation of the second rotating frame 57. During the screwing process, since the self-locking rod is threadedly connected to one side of the self-locking knob 573, after being screwed to a certain angle, the self-locking rod can be rotated, and one end of the self-locking rod will abut against the shaft of the self-locking knob 573, thereby achieving a self-locking effect. During the rotation process, the second rotating frame 57 will not only rotate on the inner side of the fixed frame 58, but also drive the second indicating rod 571 to rotate together, ensuring the synchronization and stability during the rotation process. At the same time, the rotation of the second rotating frame 57 will trigger the activity of the active rod 561, and one end of the active rod 561 gradually changes position through the connected second gear 56. In this process, the position change of the second gear 56 ensures that the second gear 56 remains in meshing with the toothed ring 55 during rotation. Even when the angle changes, the rotation of the toothed ring 55 can still transmit power to drive the second gear 56 to rotate, so that the active rod 561 rotates. The rotation of the active rod 561 further drives the rotation of the polishing wheel 572, and then drives the polishing wheel 572 to rotate for polishing. In this way, the rotation angle of the polishing wheel 572 can be accurately adjusted, thereby improving the polishing effect of the flange and ensuring that the workpiece surface is polished more evenly and finely.

[0042] In addition, the rotation angle of the polishing wheel 572 can be accurately indicated by the cooperation of the second indicator rod 571 and the second angle plate 581. The second indicator rod 571 provides an intuitive angle display, and the operator can easily adjust the angle of the polishing wheel 572 according to the mark on the indicator plate to meet the polishing requirements of different workpieces. This adjustment process is simple and accurate, ensuring accurate control of the polishing angle and effectively improving the process quality.

[0043] When the rotating frame 53 rotates, the first indicator rod 531 and the toothed ring 55 will also move together. At this time, the orientation adjustment of the active rod 561 is completed, and the self-locking knob 573 is used to control the second rotating frame 57 to adjust the angle of the active rod 561, which can further improve the degree of freedom and polishing effect of the polishing wheel 572. The rotation of the toothed ring 55 ensures that the active rod 561 and the polishing wheel 572 maintain the same rotation direction, providing continuous and stable movement, making the polishing process smoother.

[0044] After the rotating frame 53 rotates, the first indicator rod 531 will move on the surface of the second angle plate 581. It is easy to understand the horizontal direction in which the polishing wheel 572 is currently rotating. With the second indicator rod 571 and the first angle plate 52, it is possible to ensure that the polishing wheel 572 achieves the best angle control and accuracy during the polishing process. The dual adjustment mechanism not only improves the operating efficiency, but also enhances the consistency of the polishing effect, can meet different processing requirements, and improve the overall performance and accuracy of the production line.

[0045] Embodiment 2: Figure 7 and Fig.10 As shown, the rotating mechanism 3 includes a second bottom plate 31, a support plate 32 is fixedly connected to the top of the second bottom plate 31, a rotating column 34 is rotatably connected to the center of the top of the support plate 32, a first gear 33 is fixedly connected to the outer surface of the rotating column 34, and racks 35 are meshed and connected on both sides of the first gear 33. The side wall of the rack 35 is fixedly connected to a first guide block 36, and two first slide rails 37 are symmetrically fixedly connected to the top of the support plate 32. The first slide rails 37 are slidably connected to the first guide block 36, one side of one of the first guide blocks 36 is provided with a second cylinder 38, and the other first guide block 36 is provided with a support frame 321 on both sides, the bottom of the support frame 321 is fixedly connected to the support plate 32, the middle part of the support frame 321 is threadedly connected to a threaded rod 322, and the middle part of the second cylinder 38 is fixedly connected to the support plate 32.

[0046] In this embodiment, the driving force of the second cylinder 38 is passed through the connected first guide block 36, so that the first guide block 36 can move. In this process, the movement of the first guide block 36 not only pushes the rack 35 to move together, but also makes the rack 35 exert a force on the first gear 33. Due to the action of the rack 35, the first gear 33 starts to rotate, and will also drive the other rack 35 to move. The synchronous movement of the two racks 35 is transmitted through the first gear 33, which can cause the two first guide blocks 36 to slide synchronously, and the movement directions are opposite. During the synchronous movement of the two first guide blocks 36, they will also slide relative to the surface of the first slide rail 37. In this process, the first slide rail 37 can achieve a limiting effect.

[0047] This sliding limit function ensures that the rack 35 can maintain a horizontal motion trajectory when moving, avoids instability caused by offset, and ensures precise control of the system. In this process, the threaded rods 322 on both sides play a further limiting role, and the spacing between the two threaded rods 322 limits the range of motion of the first guide block 36. Any unnecessary free movement is prevented, thereby enhancing the stability of the structure.

[0048] At the same time, the rotation of the first gear 33 is also limited within a certain range, thereby avoiding system instability caused by excessive rotation. When the first gear 33 drives the rotating column 34 to rotate, the precise range of the rotation angle can be finely controlled by adjusting the threaded rod 322 or adjusting the action of the second cylinder 38. The rotation angle of the rotating column 34 determines the movement of the first rotating frame 21, thereby effectively adjusting the flange orientation inside the fixture 6. In this way, the fixture 6 can accurately adjust the position of its internal flange to meet different processing requirements, and the controllability of the system enables the operator to flexibly set the angle of the fixture 6 as needed to ensure the accuracy of each processing.

[0049] Embodiment 3: According to Figure 7 - Fig. 9 As shown, the movable mechanism 2 includes a first rotating frame 21, and a slide groove 22 is provided at the top of both ends of the first rotating frame 21. A support block 27 is fixedly connected to the middle of the first rotating frame 21, and a rotating rod 28 is rotatably connected to the middle of the two support blocks 27. A worm sleeve 25 is fixedly connected to the outer surface of one end of the rotating rod 28, and a special-shaped worm gear 24 is meshed and connected to the top of the worm sleeve 25. The top of the special-shaped worm gear 24 is fixedly connected to the movable frame 23, and both sides of the bottom of the movable frame 23 are fixedly connected to the slider 231, and the slider 231 is slidably connected to the slide groove 22. A first driving motor 26 is installed on one side of the first rotating frame 21, and the output end of the first driving motor 26 is fixedly connected to the rotating rod 28.

[0050] In this embodiment, the rotating rod 28 is rotated by the drive of the first driving motor 26, thereby driving the worm sleeve 25 to rotate together. The rotation of the worm sleeve 25 will generate a force on the special-shaped worm wheel 24, prompting the special-shaped worm wheel 24 to move in a certain direction. During the movement of the special-shaped worm wheel 24, the movable frame 23 moves accordingly, and the displacement of the movable frame 23 further drives the top clamp 6 to move synchronously. The movement of the clamp 6 realizes the precise adjustment of the position of the polishing flange, so that it can maintain an ideal angle and position during the processing process.

[0051] At the same time, during the movement of the movable frame 23, the slider 231 slides along the track of the slide 22. The sliding of the slider 231 not only plays a guiding role, but also effectively limits the movable angle of the movable frame 23, ensuring that the movable frame 23 moves within a specific range. This limiting mechanism is crucial to avoid excessive movement and ensure the precision adjustment of the flange. Under the action of the slider 231, the movable angle of the movable frame 23 is accurately controlled, further ensuring the stability and accuracy of the workpiece position during the processing process.

[0052] Through the coordinated work of the above components, the entire system can achieve precise control of the position of the polishing flange, ensuring that the flange remains in a stable and controllable state during the polishing process, thereby improving polishing quality and production efficiency.

[0053] Embodiment 4: According to Figure 1 , Figure 2 and Figure 6 As shown, the clamp 6 includes a first support clamp 61, the bottom of the first support clamp 61 is fixedly connected to the movable frame 23, the top of the first support clamp 61 is hinged with a second support clamp 62, and one side of the second support clamp 62 is fixedly connected to a locking block 63. A first cylinder 11 is installed on one side of the first base plate 1, and a fixed block 41 is fixedly connected to the output end of the first cylinder 11, and the top of the fixed block 41 is fixedly connected to the center of the top of the inner cavity of the movable frame 4, and the inner wall of one end of the first base plate 1 is fixedly connected to the second slide rail 42, and the surface of the second slide rail 42 is slidably connected to the second guide block 43, and the top of the second guide block 43 is fixedly connected to the top of the inner cavity of the movable frame 4. A plurality of telescopic rods 511 are fixedly connected to the bottom of the mounting plate 51, and the bottom of the telescopic rods 511 is fixedly connected to the top of the movable frame 4, and a first indicator rod 531 is fixedly connected to one side of the bottom of the rotating frame 53, and a locking rod 532 is threadedly connected to one end of the first indicator rod 531, and a third cylinder 7 is fixedly connected to the center of the top of the movable frame 4, and the top of the third cylinder 7 is fixedly connected to the bottom of the mounting plate 51.

[0054] In this embodiment, when performing the flange polishing operation, the flange needs to be first firmly placed inside the first support clamp 61. The first support clamp 61 is used to support the position of the flange to ensure that it does not move. Then, the flange is fixed in a suitable position by moving the second support clamp 62 hinged to the first support clamp 61 so that it is firmly clamped. The second support clamp 62 can be flexibly adjusted to adapt to the size and shape of different flanges to ensure that the flange does not slide after being clamped. In order to enhance the stability of the flange, a locking block 63 is used to lock it during the locking stage to avoid any displacement or instability of the flange during the polishing process.

[0055] During the polishing process, in order to ensure accurate work, the first cylinder 11 is first used to push the fixed block 41 to move, so that it drives the moving frame 4 to move together. The movement of the moving frame 4 affects the polishing mechanism 5 connected thereto, so that the polishing mechanism 5 can change its position, thereby adjusting the position of the polishing wheel 572. The position adjustment of the polishing mechanism 5 is to ensure that the flange surface can be accurately polished under different working conditions.

[0056] In addition, the second guide block 43 is also driven to slide together during the sliding process of the moving frame 4. The function of the second guide block 43 is to slide on the surface of the second slide rail 42, thereby achieving precise guidance. Through this guiding function, it is ensured that the moving frame 4 can remain stable during sliding without shaking or inaccurate movement, and the accuracy of the flange polishing process can also be guaranteed.

[0057] In addition, in order to further improve the stability of the system, the drive of the third cylinder 7 is also used to control the height of the mounting plate 51. When the mounting plate 51 is raised or lowered, the four telescopic rods 511 will also be extended and retracted accordingly. The extension and retraction of the telescopic rods 511 is not only for adjusting the position of the mounting plate 51, but also has a limiting function. By controlling the extension and retraction degree of the telescopic rods 511, the height of the mounting plate 51 can be accurately adjusted to achieve the effect of changing the polishing wheel 572.

[0058] The use method and working principle of the device are as follows: when performing the flange polishing operation, first place the flange in the first support clamp 61, and then clamp the flange by moving the second support clamp 62 hinged thereto to complete the fixing of the flange. During the polishing process, the first cylinder 11 pushes the fixed block 41 to move, thereby driving the mobile frame 4 to move together. The grinding mechanism 5 on the top of the mobile frame 4 changes its position accordingly, so as to adjust the position of the active rod 561. The position of the active rod 561 and the polishing wheel 572 can be adjusted by utilizing the movable characteristics of the mobile frame 4. In addition, the drive of the third cylinder 7 can control the height of the mounting plate 51 to achieve the effect of controlling the height of the polishing wheel 572. In addition, different types of fixtures 6 can be selected according to flanges of different sizes, and the polishing wheel 572 can be adjusted with a high degree of freedom to perform polishing operations on different types of flanges.

[0059] As the flange is continuously polished, when the position of the polishing wheel 572 needs to be adjusted, the self-locking knob 573 can be turned to drive the second rotating frame 57 to rotate. The second rotating frame 57 not only rotates inside the fixed frame 58, but also drives the second indicating rod 571 to rotate together. In this process, the second rotating frame 57 drives the active rod 561 to move, and the position of the second gear 56 at one end of the active rod 561 gradually changes. The active rod 561 also drives the polishing wheel 572 to move, thereby changing the polishing angle of the polishing wheel 572 and improving the polishing effect of the flange. After the second gear 56 rotates with the second rotating frame 57, it still remains in meshing with the gear ring 55. When the gear ring 55 rotates, the second gear 56 can still be affected by the force of the rotation of the gear ring 55, thereby driving the active rod 561 to rotate, so that the polishing wheel 572 is polished during rotation.

[0060] When controlling the angle of the polishing wheel 572, the angle of the polishing wheel 572 can be indicated by the bottom end of the second indicator rod 571 on the surface of the second angle plate 581, so that the polishing angle of the polishing wheel 572 can be adjusted accurately. In addition, when the rotating frame 53 rotates, the first indicator rod 531 and the gear ring 55 are driven to move together, which indirectly changes the orientation of the polishing wheel 572. The function of adjusting the orientation is added on the basis of the adjustable angle, which can further improve the polishing effect. After the rotating frame 53 rotates, the first indicator rod 531 will also move on the surface of the second angle plate 581, so that the adjusted direction angle of the polishing wheel 572 can be understood in real time.

[0061] In addition to adjusting the polishing wheel 572, the first driving motor 26 drives the rotating rod 28 to rotate, and the rotating rod 28 drives the worm sleeve 25 to rotate together. In this process, the support block 27 supports the rotating rod 28, and the worm sleeve 25 applies a force to the special-shaped worm gear 24. When the special-shaped worm gear 24 moves, it drives the movable frame 23 to move, and then drives the top clamp 6 to move, changing the position of the flange to be polished.

[0062] The driving force of the second cylinder 38 pushes the first guide block 36 connected thereto to move, and the first guide block 36 drives the rack 35 to move. The movement of the rack 35 applies a force to the first gear 33, causing the first gear 33 to start rotating. When the first gear 33 rotates, a force is applied to the other rack 35, causing the two first guide blocks 36 to move in opposite directions synchronously, and the two first slide rails 37 also move synchronously. The first slide rails 37 slide on the surface of the first guide block 36 to play a limiting role, ensuring the horizontal movement of the rack 35.

[0063] The first rotating frame 21 is driven to move by the rotating column 34 , thereby changing the orientation of the inner flange of the clamp 6 .

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
