Description

Technical Field

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

[0002] In industries such as petrochemicals and pressure vessels, flanges are critical components for pipeline connections, and the machining accuracy of their end faces directly affects sealing performance and operational safety. As industrial equipment evolves towards higher pressures and temperatures, the flatness requirement for flange end faces has increased to 0.01mm. Traditional manual polishing methods are not only inefficient (requiring 2-3 hours per flange) but also struggle to ensure consistent machining, leading to frequent sealing failures.

[0003] Currently, the following flange polishing structures are mainly used in industrial sites: magnetic adsorption polishing machines, which perform single-point polishing after fixing the flange with an electromagnet; and hydraulic clamping rotary tables, which work with oscillating grinding heads to complete end face processing. These devices usually use rigid clamping structures and rely on the operator's experience to control the polishing pressure.

[0004] Existing polishing devices suffer from insufficient clamping stability, leading to fluctuations in processing accuracy. Due to the lack of multi-stage clamping, flanges are prone to micron-level displacement during polishing. This displacement causes fluctuations in polishing pressure, resulting in defects such as "crescent marks" on the end face, which seriously affects the contact uniformity of the sealing surface. Therefore, a rapid flange end face polishing device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a flange end face rapid polishing device, which aims to improve the problem of fluctuations in processing accuracy caused by insufficient clamping stability. Due to the lack of multi-stage clamping, the flange is prone to micron-level displacement during the polishing process, which causes fluctuations in polishing pressure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flange end face rapid polishing device, including a base, a support frame fixedly connected to the upper surface of the base, a connecting plate fixedly connected to the outer wall of the support frame, a placement platform fixedly connected to the inner wall of the base, a polishing mechanism arranged above the placement platform, a second motor arranged inside the placement platform, a third gear fixedly connected to the output end of the second motor, a second gear arranged inside the placement platform, the second gear and the third gear meshing with each other, and a clamping component arranged on the inner wall of the second gear;

[0007] The clamping assembly includes a connecting rod, a connecting block, and a clamping plate. The outer wall of the connecting rod is slidably connected to the inner wall of the gear, the outer wall of the connecting block is slidably connected to the inner wall of the placement platform, the outer wall of the clamping plate is fixedly connected to one end of the connecting block, the upper surface of the connecting block is fixedly connected to the lower surface of the connecting rod, and the inner wall of the clamping plate is provided with an anti-slip component.

[0008] Furthermore, the anti-slip component includes a lead screw, a limiting rod, and an anti-slip pad. The outer wall of the lead screw is threadedly connected to the inner wall of the clamping plate, the outer wall of the limiting rod is slidably connected to the inner wall of the clamping plate, the outer wall of the anti-slip pad is fixedly connected to one end of the limiting rod, and the anti-slip pad is disposed on the outer wall of the clamping plate.

[0009] Furthermore, a motor is fixedly connected to the inner wall of the connecting plate, and a gear is fixedly connected to the output end of the motor.

[0010] Furthermore, a slide rail is fixedly connected to the outer wall of the support frame, and a pulley is slidably connected to the outer wall of the slide rail.

[0011] Furthermore, a connecting rod three is rotatably connected to the inner wall of the pulley two, and the outer wall of the connecting rod three is fixedly connected to the inner wall of the sliding plate one.

[0012] Furthermore, a rack is fixedly connected to the outer wall of the sliding plate, and the rack and gear mesh with each other.

[0013] Furthermore, the outer wall of the rack is fixedly connected to the inner wall of the polishing mechanism, and the outer wall of the polishing mechanism is fixedly connected to the sliding plate.

[0014] Furthermore, a pulley is provided inside the sliding plate two, a slide rail two is slidably connected to the inner wall of the pulley one, a connecting rod two is rotatably connected to the inner wall of the pulley one, and the outer wall of the connecting rod two is fixedly connected to the inner wall of the sliding plate two.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the second motor drives the third gear to mesh with the second gear, which drives the first connecting rod to push the connecting block, so that the clamping plate can quickly complete the initial clamping of the flange. After clamping, the screw is rotated to push the anti-slip pad to adhere to the flange surface. With the anti-rotation constraint of the limit rod, it is ensured that the anti-slip pad only produces axial displacement, the contact pressure is evenly distributed, and the flange shakes during the polishing process, avoiding the precision deviation of the polishing surface caused by displacement.

[0017] 2. In this utility model, the motor drives the gear to mesh with the rack, which in turn drives the sliding plate to slide along the slide rail. The rolling friction design of the pulley reduces the moving resistance and speeds up the horizontal adjustment. At the same time, the sliding plate moves synchronously along the slide rail through the pulley, forming a double-point support guide structure. This controls the horizontal sway of the polishing mechanism, enabling full-area polishing of the flange end face. It is suitable for polishing flanges of different diameters and can complete multi-position polishing in a single clamping, thus improving processing efficiency. Attached Figure Description

[0025] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 - Figure 3This utility model provides an embodiment of a flange end face rapid polishing device, including a base 1. The base 1 ensures that the entire device does not shake during the polishing process, ensuring polishing accuracy. A support frame 2 is fixedly connected to the upper surface of the base 1, and a connecting plate 3 is fixedly connected to the outer wall of the support frame 2. A placement platform 11 is fixedly connected to the inner wall of the base 1. The placement platform 11 is used to place the flange to be polished, providing a stable support surface for the flange. Its flat platform surface ensures that the rear end face of the flange is in a horizontal state, which facilitates the polishing mechanism 10 to perform uniform polishing. A polishing mechanism 10 is set above the placement platform 11. The polishing mechanism 10 is equipped with a hydraulic cylinder and a rotating motor inside. The hydraulic cylinder can adjust the height of the polishing head to adapt to flanges of different thicknesses. The rotating motor drives the polishing head to rotate at high speed to grind and polish the flange end face, achieving a smooth finish on the flange end face. A second motor 19 is set inside the placement platform 11. A third gear 20 is fixedly connected to the output end of the second motor 19. A second gear 18 is set inside the placement platform 11. The second gear 18 and the third gear 20 are meshed with each other. A clamping component is set on the inner wall of the second gear 18.

[0027] The clamping assembly includes a connecting rod 17, a connecting block 14, and a clamping plate 12. The outer wall of the connecting rod 17 is slidably connected to the inner wall of the gear 18, and the outer wall of the connecting block 14 is slidably connected to the inner wall of the placement platform 11. The connecting block 14 transmits the sliding thrust of the connecting rod 17 to the clamping plate 12, enabling the clamping plate 12 to complete the clamping action on the flange. The outer wall of the clamping plate 12 is fixedly connected to one end of the connecting block 14, and the upper surface of the connecting block 14 is fixedly connected to the lower surface of the connecting rod 17. An anti-slip assembly is provided on the inner wall of the clamping plate 12, which includes a lead screw 13, a limiting rod 15, and an anti-slip pad 16. The outer wall is threaded to the inner wall of the clamping plate 12. When the screw 13 rotates, it can push the anti-slip pad 16 to move towards the flange. The screw 13 achieves precise position adjustment of the anti-slip pad 16 through the screw drive, ensuring that the anti-slip pad 16 fits tightly against the flange. The outer wall of the limiting rod 15 is slidably connected to the inner wall of the clamping plate 12. The limiting rod 15 restricts the movement of the anti-slip pad 16, preventing the anti-slip pad 16 from rotating with the screw 13, ensuring that the anti-slip pad 16 only moves in a straight line and fits tightly against the flange surface. The outer wall of the anti-slip pad 16 is fixedly connected to one end of the limiting rod 15. The anti-slip pad 16 is set on the outer wall of the clamping plate 12.

[0028] Reference Figure 1 - Figure 5A motor 4 is fixedly connected to the inner wall of the connecting plate 3. A gear 5 is fixedly connected to the output end of the motor 4. A slide rail 8 is fixedly connected to the outer wall of the support frame 2. The slide rail 8 provides a guide track for the horizontal movement of the sliding plate 6, restricts the movement direction of the sliding plate 6, ensures that it slides smoothly along a straight line, and avoids deviation in the polishing position due to offset. A pulley 25 is slidably connected to the outer wall of the slide rail 8. The pulley 25 rolls along the slide rail 8, reducing the frictional resistance between the sliding plate 6 and the slide rail 8, making the horizontal movement of the polishing mechanism 10 driven by the sliding plate 6 more stable and efficient. A connecting rod 24 is rotatably connected to the inner wall of the pulley 25. The outer wall of the connecting rod 24 is fixedly connected to... A rack 7 is fixedly connected to the inner wall of the sliding plate 6 and the outer wall of the sliding plate 6. The rack 7 meshes with the gear 5. The outer wall of the rack 7 is fixedly connected to the inner wall of the polishing mechanism 10. A sliding plate 9 is fixedly connected to the outer wall of the polishing mechanism 10. The sliding plate 9 works in conjunction with the sliding plate 6. The pulley 22 inside the sliding plate 9 slides along the slide rail 21, providing auxiliary support and guidance for the horizontal movement of the polishing mechanism 10 and enhancing the stability of the movement. The sliding plate 9 is equipped with a pulley 22. The inner wall of the pulley 22 is slidably connected to the slide rail 21. The inner wall of the pulley 22 is rotatably connected to the connecting rod 23. The outer wall of the connecting rod 23 is fixedly connected to the inner wall of the sliding plate 9.

[0029] Working principle: When the flange end face needs to be polished quickly using the polishing device, the flange is placed on the placement table 11, and the motor 19 is started to drive the gear 20 to rotate. Through gear meshing, the gear 18 is driven to rotate, causing the internal connecting rod 17 to slide along the slide groove, thereby pushing the connecting block 14, realizing the clamping plate 12 to quickly clamp the flange. It can be adapted to flanges of different sizes. After clamping, the screw 13 inside the clamping plate 12 is rotated to make the anti-slip pad 16 tightly adhere to the flange surface, preventing shaking during the polishing process. The limiting rod 15 fixed to the anti-slip pad 16 can limit the rotation trend of the screw 13, ensuring that the anti-slip pad 16 only moves in a straight line and does not rotate with the screw 13.

[0030] The hydraulic cylinder inside the polishing mechanism 10 is activated to adjust the height of the polishing head. At the same time, the internal rotating motor is turned on to drive the polishing head to rotate and polish the flange end face. If the polishing position needs to be adjusted, the motor 4 on the connecting plate 3 can drive the gear 5 to rotate. The gear 5 is driven by the rack 7 to move the sliding plate 6. At this time, the pulley 25 inside the sliding plate 6 slides along the slide rail 8 to realize the horizontal position adjustment of the polishing mechanism 10 to meet the polishing requirements of different flange positions. In addition, the pulley 22 inside the sliding plate 9 fixed on the polishing mechanism 10 slides synchronously along the slide rail 21 to play an auxiliary guiding role and ensure that the polishing process is stable and smooth.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
