Description

Technical Field

[0001] This utility model relates to the field of flange processing technology, and in particular to a polishing device for flange processing. Background Technology

[0002] A flange, or simply flange, is a general term that typically refers to a disc-shaped metal body with several holes around its perimeter for connecting other components. Flanges are widely used in machinery, and their name comes from the English word "flange." The main function of a flange is to connect pipes, equipment, or other mechanical parts, achieving sealing and fixation through bolts and gaskets. A flange is a disc-shaped connecting component with a specific structure and function; it possesses high strength, rigidity, and stability, and can withstand significant pressure and torque.

[0003] During the production and processing of flanges, in order to remove defects such as burrs, scratches, and pores from the flange surface and make the surface smoother and brighter, polishing equipment is usually used to polish it. The polished flange surface is flatter and can better fit with the gasket, improving the sealing effect. This is especially important for applications that require high sealing performance (such as chemical and petroleum industries), as follows.

[0004] A search revealed patent CN210732065U, which discloses a polishing device for flange processing. The device includes a worktable, a rotating mechanism, and a fixing mechanism. Support plates are welded to both sides of the top of the worktable. A top plate is welded to the top of each of the two support plates. A cylinder is fixedly connected to the center of the top of the top plate. The output end of the cylinder is welded to one end of a piston rod. The other end of the piston rod passes through the top of the top plate and extends to the bottom, where a rotary motor is fixedly welded. The output end of the rotary motor is fixedly connected to the top of a rotating shaft via a coupling. A polishing wheel is fixedly welded to the bottom of the rotating shaft. A fixing plate is fixedly welded to the center of the top of the worktable. A rotating mechanism is fixedly connected to the top of the fixing plate. A mounting plate is fixedly connected to the fixing plate via the rotating mechanism. Fixing devices are located at both ends of the top of the fixing plate. This flange processing polishing device has a simple structure, excellent dust extraction effect, and strong practicality.

[0005] However, the above-mentioned polishing device for flange processing still has the following areas for improvement. For example, when it is working, since the dimensions of the mounting plate, mounting groove and protrusion are fixed, and the inner and outer diameters of flanges of different sizes are different, it can only be used for polishing flanges of a single size, resulting in a small range of application and poor ease of use. Therefore, its structure needs to be improved and its practicality needs to be enhanced. Utility Model Content

[0006] This utility model discloses a polishing device for flange processing. During operation, the flange is placed on two support plates with its inner hole located outside two fixed blocks. A crank handle rotates a turntable, which in turn rotates a lead screw. The lead screw engages two sliding grooves, causing the sliders to move in opposite directions. This, in turn, moves the two support plates and the two fixed blocks in opposite directions until the arc-shaped surfaces of the two fixed blocks abut against the inner walls of the flange's inner hole, thus securing the flange. After fixing the flange, polishing can be performed. Because the distance between the two fixed blocks is adjustable, it is suitable for fixing and polishing flanges of various sizes and specifications, greatly improving the device's applicability and ease of use. In summary, this device solves the problems in the prior art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model discloses a polishing device for flange processing, including a processing table, the bottom of which is fixedly connected with multiple support legs;

[0009] A flange fixing mechanism includes a first motor and a support base. The first motor is fixedly installed on the bottom of the processing table via a mounting component.

[0011] A cooling mechanism is located on top of the processing table.

[0012] Furthermore, the top of the processing table is provided with an annular groove, and the bottom of the support base is slidably connected to the annular groove through multiple sliding connectors.

[0013] Furthermore, both of the fixing blocks have anti-slip pads attached to their curved surfaces, and the anti-slip pads are made of rubber material.

[0014] Furthermore, the polishing mechanism includes a mounting base, on which a first cylinder is fixedly mounted in a through manner. A connecting seat is fixedly connected to the telescopic end of the first cylinder. The connecting seat is L-shaped. A second cylinder is fixedly mounted in a through manner on the top of the connecting seat. A mounting frame is fixedly mounted on the bottom of the second cylinder.

[0015] Furthermore, a plurality of guide rods are fixedly connected to one side of the connecting seat, and the guide rods movably pass through the mounting seat.

[0016] Furthermore, the cooling mechanism includes a water tank, which is fixedly installed on the top of the processing table and located below the polishing wheel. A drain pipe with a valve is provided on one side of the front of the water tank.

[0017] Furthermore, the back side of the water tank is provided with multiple heat dissipation fins in a through-type manner, and the heat dissipation fins are sealed at the point where they penetrate the water tank.

[0018] The present invention has the following advantages over the prior art:

[0019] 1. This technical solution is equipped with a flange fixing mechanism, which allows the flange to be fixed and limited during operation. After the flange is fixed, it can be polished. Since the distance between the two fixing blocks in the flange fixing mechanism can be adjusted, it can be used for fixing and polishing flanges of various sizes and specifications, which greatly improves the applicability of the device, makes it convenient to use, and has high practicality.

[0020] 2. This technical solution incorporates a polishing mechanism and a cooling mechanism. During operation, after the flange is fixed, the polishing mechanism, in conjunction with the first motor, performs a comprehensive polishing process on the flange. After polishing, the polishing wheel in the polishing mechanism is reset, and the second cylinder is activated to move the polishing wheel downwards until it reaches the cooling mechanism. The cooling mechanism then cools the polishing wheel with water. After the flange is unloaded and reloaded, polishing can be performed again. The effective cooling of the polishing wheel during the interval between polishing processes of two flanges significantly extends its service life, further improving the practicality of the polishing device.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] In the description of this utility model, it should be understood that the terms "surface", "side", "gap", "peripheral", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Specific Implementation Example 1:

[0031] Reference Figures 1-4 A polishing device for flange processing includes a processing table 1, and a plurality of support legs 2 are fixedly connected to the bottom of the processing table 1.

[0032] The flange fixing mechanism 3 includes a first motor 301 and a bearing seat 302. The first motor 301 is fixedly mounted on the bottom of the processing table 1 via a mounting component. The output end of the first motor 301 movably passes through the processing table 1. The bottom of the bearing seat 302 is fixedly connected to the output end of the first motor 301. A through mounting groove 303 is transversely opened inside the bearing seat 302. Two sliding grooves 304 and a through movable groove 305 are transversely opened on the top of the bearing seat 302. The movable groove 305 communicates with the mounting groove 303. Two bearing seats 306 are provided in the mounting groove 303. A lead screw 307 is rotatably mounted between the two bearing seats 306. The lead screw 307 has two threads in opposite directions. The screw 307 has two threaded sections, each symmetrically connected to a slider 308. The top of the slider 308 is located in the movable groove 305. One end of the screw 307 is fixedly connected to a turntable 309, and a crank 310 is provided at the turntable 309. Two bearing plates 311 are slidably installed at the two sliding grooves 304. The bottom of the two bearing plates 311 is fixedly connected to the top of the two sliders 308 respectively. The top of the bearing plates 311 is fixedly connected to a fixing block 312. The two fixing blocks 312 are close to each other, and the opposite sides of the two fixing blocks 312 are both arc-shaped surfaces. Polishing mechanism 4 is located at the mounting base 401. Cooling mechanism 5 is located at the top of the processing table 1.

[0033] The top of the processing table 1 is provided with an annular groove 6, and the bottom of the bearing seat 302 is slidably connected to the annular groove 6 through multiple sliding connectors; the two fixing blocks 312 are both fitted with anti-slip pads 313 on their arc surfaces, and the anti-slip pads 313 are made of rubber material.

[0034] In the specific implementation process, during operation, the flange can be placed on two bearing plates 311 with its inner hole located outside the two fixing blocks 312. Then, the turntable 309 can be rotated by the crank handle 310. The rotation of the turntable 309 drives the lead screw 307 to rotate. The rotation of the lead screw 307 can cooperate with the two sliding grooves 304 to drive the slider 308 to move in the opposite direction, thereby driving the two bearing plates 311 and the two fixing blocks 312 to move in the opposite direction until the arc-shaped surfaces of the two fixing blocks 312 abut against the inner hole and the inner walls of the flange respectively. This can limit and fix the flange. After the flange is fixed, it can be polished. Since the distance between the two fixing blocks 312 can be adjusted, it can be used for fixing and polishing flanges of various sizes and specifications, greatly improving the applicability of the device and making it more convenient to use.

[0035] The top of the processing table 1 is provided with an annular groove 6, and the bottom of the bearing seat 302 is slidably connected to the annular groove 6 through multiple sliding connectors in order to improve the overall stability of the bearing seat 302.

[0036] Among them, the two fixing blocks 312 are fitted with anti-slip pads 313 on their arc surfaces. The anti-slip pads 313 are made of rubber material to increase the contact friction between the fixing blocks 312 and the inner wall of the flange inner hole, thereby improving the fixing effect of the flange. Specific Implementation Example 2:

[0038] Reference Figure 1 and Figure 5 In a preferred embodiment, the polishing mechanism 4 includes a mounting base 401, a first cylinder 402 is fixedly mounted through the mounting base 401, a connecting base 403 is fixedly connected to the telescopic end of the first cylinder 402, the connecting base 403 is L-shaped, a second cylinder 404 is fixedly mounted through the top of the connecting base 403, a mounting frame 405 is fixedly mounted at the bottom of the second cylinder 404, a second motor 406 is fixedly mounted inside the mounting frame 405, a polishing wheel 407 is connected to the output end of the second motor 406, and the polishing wheel 407 is located below the mounting frame 405; a plurality of guide rods 408 are fixedly connected to one side of the connecting base 403, and the guide rods 408 movably pass through the mounting base 401; the cooling mechanism 5 includes a water tank 501, the water tank 501 is fixedly mounted on the top of the processing table 1, and the water tank 501 is located below the polishing wheel 407, and a drain pipe 502 with a valve is provided on one side of the front of the water tank 501;

[0039] The back side of the water tank 501 has multiple heat dissipation fins 503 that run through it, and the heat dissipation fins 503 that run through the water tank 501 are sealed.

[0040] In the specific implementation process, after the flange is fixed, the first cylinder 402 and the second cylinder 404 can be activated to extend them. The extension of the first cylinder 402 can drive the polishing wheel 407 to move horizontally until the polishing wheel 407 is above the flange. The extension of the second cylinder 404 can drive the polishing wheel 407 to move downward until the polishing wheel 407 contacts the surface of the flange. At this time, the first motor 301 and the second motor 406 can be activated. The operation of the first motor 301 can drive the bearing seat 302 to rotate, thereby driving the flange to rotate. The operation of the second motor 406 can drive the polishing wheel... 407 rotates to perform a full polishing process on the flange. After the full polishing of the flange is completed, the polishing wheel 407 can be reset, and then the second cylinder 404 is started to drive the polishing wheel 407 to move down until the polishing wheel 407 moves down into the water tank 501. The polishing wheel 407 can be cooled down by the cooling water added in the water tank 501 beforehand. After the flange is unloaded and reloaded, the polishing work can be carried out again. During the interval between the polishing of the two flanges, the polishing wheel 407 can be effectively cooled down, which can greatly extend the service life of the polishing wheel 407.

[0041] Among them, the guide rod 408 can improve the overall stability of the connecting seat 403, making it less prone to shaking;

[0042] The water tank 501 has multiple heat dissipation fins 503 arranged in a through-type pattern on one side of its back. This is to accelerate the cooling of the water in the water tank 501 after heat exchange with the polishing wheel 407, ensuring that the cooling water can still exchange heat with and cool the polishing wheel 407 when it enters the water tank 501 again. The heat dissipation fins 503 are sealed at the point where they penetrate the water tank 501 to ensure that there is no leakage at the point where the heat dissipation fins 503 penetrate the water tank 501.

[0043] Working principle: During operation, the flange can be placed on two bearing plates 311, with its inner hole located outside the two fixing blocks 312. Then, the turntable 309 can be rotated by the crank handle 310. The rotation of the turntable 309 drives the lead screw 307 to rotate. The rotation of the lead screw 307 engages with the two sliding grooves 304, causing the slider 308 to move in the opposite direction. This, in turn, causes the two bearing plates 311 and the two fixing blocks 312 to move in the opposite direction until the arc-shaped surfaces of the two fixing blocks 312 abut against the inner walls of the flange's inner hole. This limits and fixes the flange. After the flange is fixed, it can be polished. Since the distance between the two fixing blocks 312 is adjustable, it can be used for fixing and polishing flanges of various sizes and specifications, greatly improving the applicability of the device and making it more convenient to use.

[0044] After the flange is secured, the first cylinder 402 and the second cylinder 404 can be activated to extend them. The extension of the first cylinder 402 can drive the polishing wheel 407 to move horizontally until it is above the flange. The extension of the second cylinder 404 can drive the polishing wheel 407 to move downward until it contacts the flange surface. At this point, the first motor 301 and the second motor 406 can be activated. The operation of the first motor 301 can drive the bearing seat 302 to rotate, thereby rotating the flange. The operation of the second motor 406 can drive the polishing wheel 407 to rotate. After the flange is fully polished, the polishing wheel 407 can be reset, and the second cylinder 404 can be started to move the polishing wheel 407 down until it reaches the water tank 501. The polishing wheel 407 can be cooled down by the cooling water added to the water tank 501. After the flange is unloaded and reloaded, the polishing work can be carried out again. During the interval between polishing the two flanges, the polishing wheel 407 can be effectively cooled down, which can greatly extend the service life of the polishing wheel 407.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
