[0001] The utility model relates to the technical field of weld grinding, in particular to a high-quality stainless steel welded pipe weld grinding device. Background Art

[0002] Stainless steel welded pipe refers to a steel pipe made by rolling steel or steel strip through a unit and a mold and then welding it. Due to the welding process used, a weld will be formed on the stainless steel welded pipe, and the unevenness at the weld not only affects the aesthetics of the stainless steel welded pipe, but also reduces its practicality. Therefore, it needs to be polished to make the surface of the stainless steel welded pipe smooth and flat.

[0003] Currently, stainless steel welded pipes are usually ground with a single grinding wheel. The welds after grinding are not smooth enough, which reduces the quality of the stainless steel welded pipes after grinding. Therefore, we propose a high-quality stainless steel welded pipe weld grinding device. Utility Model Content

At the same time, it is suitable for grinding the welds of stainless steel welded pipes of different diameters, thereby improving the applicability and solving the problem that the current stainless steel welded pipe is usually ground by a single grinding wheel, and the smoothness of the weld after grinding is insufficient, thereby reducing the quality of the stainless steel welded pipe after grinding.

[0005] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a high-quality stainless steel welded pipe weld grinding device, comprising a grinding frame, wherein a cylinder and a rotating motor are fixedly installed at positions on both sides of the outer surface of the grinding frame, the end of the rotating motor output shaft is fixedly connected to a first conical cylinder, the end of the cylinder output shaft is rotatably connected to a second conical cylinder, an electric push rod is fixedly installed on the upper surface of the grinding frame, the end of the electric push rod is fixedly connected to an electric slide, the sliding end of the electric slide is fixedly installed with a steering motor, the end of the steering motor output shaft is fixedly connected to a turntable, a first motor is symmetrically fixedly installed at positions near the front surface and the rear surface of the lower surface of the turntable, the ends of the two first motor output shafts are both fixedly connected to a first grinding wheel, a second motor is symmetrically fixedly installed at positions on both sides of the lower surface of the turntable, and the ends of the two second motor output shafts are both fixedly connected to a second grinding wheel.
