The invention relates to the technical field of steel pipe grinding equipment, and discloses a precise long and thin steel pipe coping device which comprises a pipe fitting and a detection frame, the detection frame is located in an inner cavity of the pipe fitting, a sealing check ring slidably connected with the inner wall of the pipe fitting is fixedly installed on the side wall of the detection frame, and a grinding frame is movably installed at one end of the detection frame. A grinding block used for grinding a welding spot is movably installed on the side wall of the grinding frame, and an air conveying cavity is formed in the inner wall of the detection frame. According to the invention, the grinding block and the detection frame are arranged in the pipe fitting, so that in the process of processing the welding spots on the inner wall of the pipe fitting, the detection frame slides on the inner wall of the pipe fitting by filling air flow at one end, so that the protruding welding spots in the pipe fitting are detected, and the grinding block is driven to rotate when the detection frame is stopped by the welding spots to move; therefore, welding spots at the front end of the detection frame are polished, the phenomena that long and thin pipe fittings are not easy to polish and polishing is uneven are avoided, and finally the purpose of easy polishing is achieved.
Description
technical field [0001] The invention relates to the technical field of steel pipe grinding equipment, in particular to a grinding device for precision slender steel pipes. Background technique [0002] In the process of processing steel into steel pipes, it generally goes through the steps of flattening, rough forming, welding, deburring, fine forming, and cutting. In order to ensure the required length, integrally formed steel pipes are more troublesome. The steel pipes are welded together to form the length required in actual use. [0003] After the slender steel pipe is welded, a welding spot will be left at the joint of the inner wall of the steel pipe. At present, the welding point of the slender steel pipe is mainly processed by extending the grinding head into the steel pipe and rotating the external drive shaft. , to achieve the grinding head to the inside of the steel pipe, and in the actual application process, because the length of the drive rod is longer, the en...
