Description

Technical Field

[0001] This utility model relates to the field of flange polishing, specifically a polishing device for the production of large flanges. Background Technology

[0002] Polishing equipment, also known as grinding equipment, uses polishing tools and abrasive particles or other polishing media to modify the surface of workpieces. In production, it is often used to polish and refurbish flanges that have been used and have rust or other contamination on their surface.

[0003] In the present technology, the surface of flanges is generally rough after manufacturing, so polishing equipment is used to grind the surface of the flanges.

[0004] Chinese Patent CN209868134U discloses a flange processing and polishing device, including a base box. A base plate is rotatably connected to the top of the base box, and a support cylinder is fixed to the bottom outer wall of the base plate. A first motor is fixed to one side of the bottom inner wall of the base box, and a connecting ring is fixed to the output shaft of the first motor. The outer circumference of the connecting ring meshes with the outer circumference of the support cylinder. A fixing rod is rotatably connected to the middle position of the top outer wall of the base plate, and a second motor is connected to the bottom end of the fixing rod. This invention uses an inner grinding roller to mount the inner circle of the flange. An electric guide rail lowers the fixing seat, allowing the clamping mechanisms at the top and bottom to clamp the flange from both sides. The motor rotates the base plate, causing the flange and top plate to rotate, thus simultaneously polishing the inner and outer circles of the flange using both inner and outer grinding rollers. This avoids the need to change the flange's fixing method and improves the overall efficiency of the processing operation.

[0005] However, the above-mentioned technical solutions are not applicable to flanges of different sizes when polishing the inner ring surface of the flange, thus reducing the practicality of the polishing equipment. Therefore, this utility model proposes a polishing device for the production of large flanges to solve the above-mentioned technical problems. Utility Model Content

[0024] Example 1: Please refer to Figures 1-4 This utility model provides a technical solution: a polishing device for the production of large flanges, the polishing device for the production of large flanges includes: a support platform 1, a placement groove 2 is provided on the surface of the support platform 1, an electric push rod 3 is provided in the placement groove 2, and a moving plate 4 is provided at the lifting end of the electric push rod 3.

[0025] Support frame 5, a limit frame 6 is provided on the surface of support frame 5, a second electric push rod 7 is provided at the bottom of limit frame 6, and a drive motor 8 is provided at the lifting end of the second electric push rod 7;

[0026] Positioning seat 9, a movable screw 10 is provided inside the positioning seat 9, a positioning frame 11 is screwed onto the surface of the movable screw 10, and a polishing rod 12 is provided at one end of the positioning frame 11;

[0027] When the flange needs to be positioned, it is first positioned by the electric push rod 3. When the inner ring surface of the flange needs to be ground and polished, the two sets of positioning frames 11 can be moved by rotating the moving screw 10, so that the two sets of polishing rods 12 can easily contact the inner ring surface of flanges of different sizes. Then the drive motor 8 can be started to rotate the polishing rods 12, so that the inner ring surface of flanges of different sizes can be ground and polished more conveniently.

[0028] Example 2: Based on Example 1, a movable plate 4 is provided to facilitate the positioning of the flange. Two sets of placement slots 2 are provided, and the two sets of placement slots 2 are symmetrically distributed about the center line of the long side of the support platform 1.

A positioning plate 13 is provided on the surface of the movable plate 4. An arc-shaped groove is provided on the side of the positioning plate 13. An arc-shaped plate 14 is provided on the other side of the positioning plate 13.

[0029] When polishing the inner ring surface of the flange is required during use, the electric push rod 3 can be started directly to clamp the outer ring surface of the flange using the positioning plate 13 on the surface of the moving plate 4, thereby fixing the flange. The positioning plate 13 has an arc groove on its side, which increases the contact area between the positioning plate 13 and the outer ring surface of the flange, thus increasing the positioning stability. When polishing the outer ring surface of the flange is required, the flange can be placed on the two sets of positioning plates 13, and then the electric push rod 3 can be started to position the inner ring surface of the flange using the arc plate 14 on the side of the positioning plate 13, which is more convenient.

[0030] Example 3: Based on Example 2, a positioning seat 9 is provided to facilitate grinding of flanges of different sizes.

[0031] When adjusting the spacing between the two sets of polishing rods 12 according to different flange sizes, the moving screw 10 can be rotated in conjunction with the limit bearing 18, so that the two sets of positioning frames 11 can move in opposite directions within the moving groove 16. This allows the polishing rods 12 to be used to polish flanges of different sizes. Then, the second electric push rod 7 can be activated to move the polishing rods 12 downwards. With the help of the drive motor 8, the polishing rods 12 can be rotated to polish the inner or outer ring surface of the flange.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
