Hardware pipe fitting inner wall grinding device and grinding method thereof

Abstract

The invention discloses a hardware pipe fitting inner wall grinding device and a grinding method thereof. The device comprises a mounting plate, a grinding sleeve, a main shaft and a motor, wherein the grinding sleeve is mounted on the left side of the mounting plate, the left end of a straw is fixed on an annular plate, the annular plate is rotatably mounted in an annular groove on the right endface of the mounting plate, and the right end of the straw communicates with the bottom end of an air supply box, and the bottom end of the air supply box is distributed oblique to the right side. According to the hardware pipe fitting inner wall grinding device and the grinding method thereof, rust removal operation can be conducted on the interior of a horizontally distributed long-distance pipeline in real time while the inner wall of a pipe fitting is ground, so that the problem that the grinding efficiency is reduced due to accumulation of rusty debris is effectively avoided, meanwhile, the grinding device guarantees that a corner of the pipe fitting of a square or other special-shaped structure can be fully ground through innovative design of the grinding structure, no grinding deadangle exists, operation is very convenient, and an application range of the grinding device is greatly expanded.

Description

technical field [0001] The invention relates to the technical field of hardware processing, in particular to a grinding device and a grinding method for the inner wall of a hardware pipe. Background technique [0002] Hardware pipe fittings are made of metal and are closed around the surrounding, with both ends sealed or open pipe structures. They are widely used in many fields. In most application scenarios, the inner and outer walls of hardware pipes need to maintain a certain degree of smoothness or ensure no Therefore, it is necessary to use the corresponding grinding device to grind the pipe fittings. The pipe fittings with larger diameters can be polished separately from the inner wall by grinding wheels / rollers or sandblasting. The following problems exist when caliber fittings: [0003] During the grinding process, in the case of long pipe fittings, it is necessary to keep the pipe fittings in a horizontal state to ensure that they do not occupy too much space.

Problems solved by technology

[0004] The purpose of the present invention is to provide a grinding device and grinding method for the inner wall of hardware pipe fittings, so as to solve the problem that in the grinding process proposed in the above background technology, in the case of long pipe fittings, it is necessary to keep the pipe fittings in a horizontal state to ensure that the occupied space will not be too large. Correspondingly, during the grinding process, the rust or other impurities removed on the inner wall cannot be easily discharged, resulting in the accumulation of rust debris inside the pipe fittings, affecting the working efficiency of the grinding device and reducing the grinding effect
