Description

Technical Field

[0001] The invention relates to the technical field related to steel pipe processing, and in particular to a steel pipe internal grinding machine with a synchronous grinding function. Background Art

[0002] When steel pipes are produced from steel pipe factories, the inner surface of the steel pipes is usually accompanied by scars and wrinkles. In order to make the inner surface of the steel pipes smoother, an internal grinder is usually used to grind the inner surface of the steel pipes.

[0003] After searching, it is found that the typical internal grinding machine in the prior art is CN213438670U, a steel pipe internal grinding machine, which relates to the technical field of internal grinding machines, including an internal grinding machine body surrounding a grinding wheel head, an electric telescopic rod fixedly installed in the middle of the internal grinding machine body, a motor fixedly installed on the side of the electric telescopic rod away from the internal grinding machine body, a grinding wheel head fixedly connected to the output end of the motor, and a steel pipe embedded in the outer surface of the grinding wheel head. In the utility model, a semicircular ring block is installed, and a rubber layer is arranged on the inner side of the semicircular ring block. When the outer side of the grinding wheel head contacts the inner side of the steel pipe, the slider moves in the slide groove to push the fixed plate to the side close to the electric telescopic rod, and the semicircular ring block is moved to the steel pipe through the connecting rod until the rubber layer on the inner side of the semicircular ring block is tangent to the steel pipe, and the bolt is rotated and embedded between the fixed blocks to fix the steel pipe, so as to prevent the steel pipe from moving during grinding, resulting in uneven grinding of the inner surface of the steel pipe.

[0004] To sum up, when the existing internal grinder is in use, the grinding head can only enter the steel pipe from one end thereof for grinding. When the steel pipe is long, the working efficiency of the internal grinder is low during grinding. At the same time, when the existing internal grinder is in use, due to the different lengths of the steel pipes, the fixed position cannot be adaptively adjusted according to the length or distance, which reduces the practicality of use. In view of the above problems, it is necessary to improve the existing equipment. Summary of the invention
