Embodiment Construction

[0015] The present invention will be described in further detail below by means of specific embodiments:

[0016] The reference signs in the accompanying drawings of the specification include: a servo motor 1, an eccentric wheel 2, a polishing rod 3, a water inlet 4, a sealing cover 5, and a stainless steel pipe 6.

[0017] Such as figure 1 , figure 2 As shown, the polishing device for the inner wall of a stainless steel pipe fitting includes a servo motor 1, an eccentric wheel 2, a polishing rod 3 and a sealing cover 5. The eccentric wheel 2 is installed on the output shaft of the servo motor 1, and the distance between the center of rotation of the eccentric wheel 2 and the grinding rod 3 is equal to the inner wall radius of the stainless steel pipe 5. The grinding rod 3 is a hollow grinding rod, and the grinding rod 3 is filled with polycrystalline diamond grinding fluid. The grinding rod 3 is provided with a water outlet hole. The aperture of the water outlet hole is 2 ...

Abstract

The invention belongs to the technical field of grinding for the interiors of pipes, and particularly discloses a polishing device for the inner wall of a stainless steel pipe fitting. The polishing device comprises a drive motor and a grinding bar and further comprises an eccentric wheel. The eccentric wheel is fixed to an output shaft of the drive motor. The grinding bar is fixed to the eccentric wheel. The distance between the rotating center of the eccentric wheel and the grinding bar is equal to the radius of the inner wall of the stainless steel pipe fitting. The grinding bar is hollow, grinding liquid is contained in the grinding bar, water outlet holes are formed in the grinding bar along the axis of the grinding bar, and a water inlet hole is formed in the end, close to the eccentric wheel, of the grinding bar. The grinding bar is made to stretch into the stainless steel pipe fitting, the eccentric wheel is driven by the drive motor to rotate and drives the grinding bar to rotate, the grinding bar is promoted to be in contact with the inner wall of the stainless steel pipe fitting, and therefore the inner wall of the stainless steel pipe fitting is ground. In addition, when the grinding bar rotates, grinding materials in the grinding bar are thrown out of the water outlet holes to impact the inner wall of the stainless steel pipe fitting under the action of centrifugal force.

Description

technical field [0001] The invention belongs to the technical field of internal grinding of pipes, and in particular relates to a polishing device for the inner wall of a stainless steel pipe fitting. Background technique [0002] Stainless steel pipe fittings have good mechanical properties and corrosion resistance, and are widely used in aerospace, marine, nuclear energy, medical equipment, petrochemical and other fields. Aluminum pipes have good corrosion resistance, and are mainly used for high-end fluid transportation pipes. In recent years, with the development and innovation of technology, people's demand for stainless steel pipe fittings is increasing day by day, and their quality requirements are also increasing. Since reducing the roughness of the inner wall of stainless steel pipe fittings can reduce the resistance of the inner wall to the fluid and the adsorption effect of materials on the inner wall, people have higher and higher requirements for the roughness o...
