Description

Technical Field

[0001] This utility model belongs to the field of flange grinding equipment, specifically relating to an automated grinding equipment for flange sealing surfaces. Background Technology

[0002] Flange sealing surface grinding equipment is a type of mechanical equipment specifically used to process flange sealing surfaces. It is mainly used to improve the smoothness and precision of flange sealing surfaces to ensure the sealing performance and reliability of flange connections. Grinding can remove minor unevenness on the flange surface, reduce roughness, thereby ensuring a tight fit between flanges and preventing leakage.

[0003] The sealing surface of a flange generally refers to the surface on which the flange contacts another flange or equipment and forms a seal. When grinding the sealing surface of a flange, existing small flange grinding equipment often requires operators to manually center the flange. Furthermore, when grinding flanges of different thicknesses, operators also need to manually adjust the grinding height of the grinding disc. This operation method is not only very time-consuming and labor-intensive, but also has low automation. Traditional small grinding equipment often cannot completely block the metal shavings generated during grinding, which causes some metal shavings to fly outward, thereby affecting the personal safety of operators.

[0004] Therefore, in view of the problems of low automation and certain safety hazards in the use of existing small flange grinding equipment, an automated flange sealing surface grinding equipment is developed. By adding an automated center positioning and clamping structure, a self-adjusting grinding height structure and a debris anti-splashing structure to the flange grinding equipment, the flange grinding equipment can perform efficient and highly automated grinding work, and avoid metal debris flying everywhere during grinding, which may affect the personal safety of operators.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] Please see Figures 1-7 This utility model provides an embodiment: an automated grinding device for flange sealing surfaces, including a grinding machine body 1, a protective shell 3, a hydraulic cylinder 4, and a rotary motor 15, as well as a rotating disk 5, grippers 20, and a servo motor 18. A support frame 11 is fixedly connected to the rear center of the upper edge of the grinding machine body 1. A second groove 10 is formed through the upper and lower ends of the support frame 11. A hydraulic cylinder 4 is fixedly connected inside the second groove 10. A grinding disk 14 is fixedly connected to the lower end of the output end of the hydraulic cylinder 4. A protective shell 3 is hinged to the rear side of the upper edge of the grinding machine body 1. A first groove 9 is formed at the center of the upper end of the grinding machine body 1. A rotary motor 18 is fixedly connected to the inner wall of the first groove 9. The upper end of the output end of the rotary motor 15 is fixedly connected to a rotating disk 5. The upper end of the rotating disk 5 has three sets of fourth grooves 16 that are equidistantly distributed around the outer wall of the rotating disk 5. The inner wall of the outer side of the fourth groove 16 has a motor groove 23. A servo motor 18 is fixedly connected in the motor groove 23. One end of a lead screw 19 is fixedly connected to the output end of the servo motor 18. The other end of the lead screw 19 is rotatably installed on the inner wall of the fourth groove 16. The inner wall of the fourth groove 16 is fixedly connected to a guide rail 17 that is symmetrically distributed front and back. The lower end of the gripper 20 is fixedly connected to a movable block 21. The front and rear ends of the movable block 21 are provided with threaded grooves 22 and two sets of sliding grooves 24 that are symmetrically distributed left and right.

[0029] Three sets of servo motors 18 drive lead screws 19 to drive three sets of movable blocks 21 and grippers 20 to clamp the inner circle of the flanges, so as to automatically center and position the inner rings of flanges of different specifications placed on the rotating disk 5. This eliminates the need for manual positioning by the user and improves the effect and efficiency of the grinding machine body 1 in grinding the flanges. The grinding disc 14 driven by the hydraulic cylinder 4 can adjust the grinding height of the grinding disc 14 according to the thickness of the flange. The two work together to achieve efficient automated grinding. The protective shell 3 can cover the flange during grinding to prevent the debris generated by the flange during grinding from flying outward and affecting the personal safety of the user.

[0030] Please see Figures 3-7 In this embodiment, a vacuum cleaner 2 is installed at the rear end of the grinding machine body 1, and a CNC computer 6 is fixedly connected to the right edge of the grinding machine body 1. During use, the vacuum cleaner 2 can provide suction to the suction pipe 13, while the CNC computer 6 can automatically control the drive of the servo motor 18, rotary motor 15, and hydraulic cylinder 4 based on the flange processing data, so that the flange and grinding disc 14 can perform efficient automated grinding work in a one-to-one correspondence. A slot 7 is provided on the front side of the upper edge of the grinding machine body 1, and a locking block 26 is fixedly connected to the lower edge of the protective shell 3. The locking block 26 is adapted to the slot 7. During use, the slot 7 and the locking block 26 assist in rotating and fixing the protective shell 3 at the upper end of the grinding machine body 1 to prevent it from accidentally opening during the grinding process. A notch 25 is provided at the upper end of the protective shell 3, which is adapted to the support frame 11. The lower end of the protective shell 3 is connected to the upper end of the grinding machine body 1. The notch 25 fits snugly with the support frame 11 during use, ensuring the airtightness of the protective shell 3 when closed while preventing the support frame 11 from affecting the rotation and opening of the protective shell 3. The upper end of the grinding machine body 1 is provided with symmetrically distributed arc-shaped grooves 8, and the lower end of the arc-shaped grooves 8 is provided with symmetrically distributed third grooves 12. The arc-shaped grooves 8 and the third grooves 12 are interconnected. During use, the notch-shaped arc-shaped grooves 8 can absorb the debris generated during flange grinding with a large suction area, thereby improving the effect and efficiency of debris absorption and treatment during grinding, and preventing debris from affecting the flange grinding work. A suction pipe 13 is installed in the third groove 12, and the suction pipe 13 is interconnected with the arc-shaped grooves 8. The tail end of the suction pipe 13 is fixed to the left and right ends of the vacuum cleaner 2. During use, the suction pipe 13 can connect the vacuum cleaner 2 and the arc-shaped grooves 8 so that the debris generated during grinding can be absorbed into the vacuum cleaner 2 for storage.

[0031] Please see Figures 5-6 In this embodiment, the screw groove 22 is adapted to the lead screw 19, and the inner wall of the sliding groove 24 is in contact with the outer wall of the guide rail 17. In use, the guide rail 17 and the sliding groove 24 can improve the stability of the movable block 21 driving the cleaver 20 to adjust its displacement along the inner wall of the fourth groove 16. The lower end of the rotating disk 5 is in contact with the upper end of the grinding machine body 1, and the rotating disk 5 corresponds one-to-one with the grinding disk 14. The inner wall of the fourth groove 16 is in contact with the outer wall of the movable block 21. In use, the lower end of the rotating disk 5 is in contact with the upper end of the grinding machine body 1, which can improve the stability of the rotating disk 5 when rotating at a constant speed. The lead screw 19 is located between the guide rails 17, and a rubber pad is fixed to the outer edge of the cleaver 20. The lower end of the cleaver 20 is in contact with the upper end of the rotating disk 5. In use, the rubber pad fixed to the outer side of the cleaver 20 can prevent the metal cleaver 20 from scratching the inner wall of the flange.

[0032] When using it, first pull the handle on the protective housing 3 to turn and open the protective housing 3, then put the flange to be ground on the rotating plate 5 and make the three sets of jaws 20 located at the inner circle of the flange, then turn and close the protective housing 3, and press the protective housing 3 to install the clamping block 26 into the clamping groove 7.

[0033] Next, the machining data of the flange is input into the CNC computer 6. The CNC computer 6 analyzes the machining data and starts three sets of servo motors 18 based on the machining data. The servo motors 18 drive the lead screw 19 to drive three sets of movable blocks 21 and grippers 20 to clamp the inner circle of the flange placed on the rotary table 5. This automatically centers and clamps the inner circle of the flange. Then, the CNC computer 6 starts the rotary motor 15 and the hydraulic cylinder 4. The rotary motor 15 drives the rotary table 5 and the fixed flange to rotate at a uniform speed. The hydraulic cylinder 4 pushes the grinding disc 14 down to approach the fixed flange until their surfaces come into contact and grinding begins, thus realizing the flange grinding work.

[0034] While the flange is being ground, the CNC computer 6 starts the vacuum cleaner 2 to suck up the debris generated during flange grinding from the two arc-shaped grooves 8 into the suction pipe 13 and transport it into the vacuum cleaner 2 for storage.

[0035] After grinding is complete, as described above, open the protective housing 3 and remove the ground flange from the jaws 20.

[0036] Through the above steps, three sets of servo motors 18 drive the lead screw 19 to drive three sets of movable blocks 21 and grippers 20 to clamp the inner circle of the flange, so as to automatically center and position the inner ring of the flange of different specifications placed on the rotating disk 5. With the help of the grinding disk 14 driven by the hydraulic cylinder 4, the grinding height of the grinding disk 14 can be adjusted according to the thickness of the flange, which can improve the grinding effect and efficiency of the grinding machine body 1 on the flange. The protective shell 3 can cover the flange during grinding to prevent the debris generated by the flange during grinding from flying outward and affecting the personal safety of the user. This solves the problem that the existing small flange grinding equipment has a low degree of automation and certain safety hazards.

[0037] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
