Description

Technical Field

[0001] The utility model relates to a polishing wheel for a stainless steel intake and exhaust pipe flange, belonging to the technical field of flange polishing equipment. Background Art

[0002] A flange is also called a blind flange or a flange; it is a part that connects pipes to each other and is connected to the pipe end. There are holes on the flange, and bolts are used to tightly connect the two flanges. Gaskets are used to seal between the flanges. At the end of two pipes that need to be connected, a flange is installed on each. For low-pressure pipes, threaded flanges can be used, and for pressures above four kilograms, welded flanges are used; usually during the production process of flanges, they need to be polished, and then a flange polishing device is required.

[0003] However, when the existing flange processing polishing device polishes a flange, it is necessary to separately polish the inner circle part and the outer circle part of the flange, and the inner circle part and the outer circle part of the flange cannot be polished simultaneously. Now there is an urgent need for a polishing wheel for a stainless steel intake and exhaust pipe flange to solve the above problems. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a polishing wheel for a stainless steel intake and exhaust pipe flange to solve the problems put forward in the above background art. The utility model designs a combined grinding and polishing wheel structure, which can simultaneously perform grinding operations on the inner circle part and the outer circle part of the flange.

[0005] To achieve the above purpose, the utility model is realized through the following technical solutions: A polishing wheel for a stainless steel intake and exhaust pipe flange includes a base, a lower support ring, and a pressing plate. A first motor is installed in the middle of the upper end of the base. A support disc is installed at the end of the first motor shaft. The lower support ring is fixed on the upper end of the support disc. A flange is placed on the upper end of the lower support ring. A bracket is arranged on the upper end of the base. An electric push rod is installed in the middle of the lower end of the bracket. A fixed inner plate is installed on the lower side of the movable end of the electric push rod. The pressing plate is slidably sleeved outside the fixed inner plate through balls. An upper support ring is fixed at the lower end of the pressing plate. An electric telescopic rod is installed on the right side of the lower end of the bracket. A third motor is installed at the movable end of the electric telescopic rod. An outer rubber grinding wheel group is installed at the movable end of the third motor. A second motor is installed on the upper right side inside the fixed inner plate. An inner rubber grinding wheel group is installed at the end of the second motor shaft.

[0006] Furthermore, metal rods are installed on both the left and right sides of the upper end of the base. Universal balls are installed at the upper ends of the two metal rods. The fixed ends of the two universal balls are slidably attached to the lower end surface of the support disc.

[0007] Furthermore, a controller is installed on the upper right side of the bracket.

[0008] Further, the inner rubber grinding wheel group is slidably attached to the right end of the inner side of the flange.

[0009] Further, the upper support ring abuts against the upper end of the flange.

[0010] Further, the outer rubber grinding wheel group is slidably attached to the right side of the flange.

[0011] Advantages of the present utility model: A polishing wheel for a stainless steel intake and exhaust pipe flange of the present utility model.

Specific Embodiments

[0017] To make the technical means, creative features, achieved purposes, and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please refer to Figures 1 - 3, the present utility model provides a technical solution: a polishing wheel for a stainless steel intake and exhaust pipe flange, comprising a base 1, a lower support ring 7 and a pressing plate 10. A first motor 2 is installed in the middle of the upper end of the base 1, and a support disk 17 is installed at the shaft end of the first motor 2. The lower support ring 7 is fixed to the upper end of the support disk 17. A flange 8 is placed on the upper end of the lower support ring 7. A support 13 is arranged on the upper end of the base 1. An electric push rod 12 is installed in the middle of the lower end of the support 13. A fixed inner plate 11 is installed on the lower side of the movable end of the electric push rod 12. The pressing plate 10 is slidably sleeved outside the outer end of the fixed inner plate 11 through balls. An upper support ring 9 is fixed to the lower end of the pressing plate 10. An electric telescopic rod 14 is installed on the right side of the lower end of the support 13. A third motor 15 is installed at the movable end of the electric telescopic rod 14. An outer rubber grinding wheel set 16 is installed at the movable end of the third motor 15. A second motor 5 is installed on the upper right side inside the fixed inner plate 11. An inner rubber grinding wheel set 6 is installed at the shaft end of the second motor 5. This design solves the problem that the original device cannot polish the inner and outer circles of the flange simultaneously.

[0019] As the first embodiment of the present utility model: Metal rods are installed on both the left and right sides of the upper end of the base 1. Universal balls 3 are installed at the upper ends of the two metal rods. The fixed ends of the two universal balls 3 are slidably attached to the lower end surface of the support disk 17. By adding the universal balls 3, when the support disk 17 is driven to rotate, they can roll in place.

[0020] A controller 4 is installed on the upper right side of the support 13. By adding the controller 4, the first motor 2, the second motor 5, the third motor 15, the electric push rod 12 and the electric telescopic rod 14 can be controlled. The inner rubber grinding wheel set 6 is slidably attached to the right end inside the flange 8. When the inner rubber grinding wheel set 6 is driven to rotate, the right end inside the flange 8 can be polished. The upper support ring 9 abuts against the upper end of the flange 8. By adding the upper support ring 9, the flange 8 can be pressed, and the displacement phenomenon of the flange 8 during the polishing process can be prevented. The outer rubber grinding wheel set 16 is slidably attached to the right side of the flange 8. When the outer rubber grinding wheel set 16 is driven to rotate, the outer right side of the flange 8 can be polished.

[0021] As the second embodiment of the present utility model: In actual use, place the flange 8 on the upper right side of the upper support ring 7. Start the electric push rod 12 through the controller 4, so that the movable end of the electric push rod 12 can drive the fixed inner plate 11, the pressing plate 10, the upper support ring 9, the second motor 5 and the inner rubber grinding wheel group 6 to move downward until the inner rubber grinding wheel group 6 moves to the inside of the flange 8. Then, slightly pull the flange 8 to the left, so that the inner rubber grinding wheel group 6 is in sliding contact with the right end inside the flange 8. Immediately afterwards, the upper support ring 9 presses down on the flange 8 (at this time, the flange 8 is directly above the lower support ring 7 and directly below the upper support ring 9). Then, start the second motor 5, and the second motor 5 drives the inner rubber grinding wheel group 6 to rotate, so as to polish the right end inside the flange 8. Then, start the electric telescopic rod 14, so that the movable end of the electric telescopic rod 14 can drive the third motor 15 to move downward, and then the outer rubber grinding wheel group 16 is driven to move downward accordingly until the outer rubber grinding wheel group 16 is in sliding contact with the right side of the flange 8. Start the third motor 15, and the third motor 15 can drive the outer rubber grinding wheel group 16 to rotate, so as to polish the right side outside the flange 8. Then, start the first motor 2, and the first motor 2 drives the support disc 17 to rotate, and then the lower support ring 7, the flange 8, the upper support ring 9 and the pressing plate 10 can be driven to rotate (due to the setting of the balls, the fixed inner plate 11 will not be driven to rotate). Thus, synchronous grinding operations can be carried out on the inner and outer sides of the flange 8.
