Abstract

The invention discloses a special grinding machine for a pipeline inner hole, which comprises a spring clamp, a limiting plate (6), a manual grinding machine (4) and a grinding head (1); the limiting plate (6) is fixed to the spring clamp; the manual grinding machine (4) is located in the limiting plate (6); a compact spring (7) is arranged between the manual grinding machine (4) and the limiting plate (6); and the grinding head (1) is connected with the manual grinding machine (4) after passing through the spring clamp. The special grinding machine for the pipeline inner hole provided by the invention has the advantages of high efficiency, easy quality control, lower requirements on labor force and technique, and the like, and the grinding operation can be finished by clamping and dismounting the special grinding machine and starting and stopping power only in the whole working process.

Description

technical field [0001] The invention relates to a special grinding machine for the inner opening of a pipeline. Background technique [0002] In shipbuilding and other industries, a large number of pipes are involved, which are generally made by hand. Each ship involves tens of thousands of pipes, including a large number of hydraulic pipes or other pipes with a diameter of less than 30mm. After the flange is welded, the inner opening needs to be polished. At present, the method is purely manual. Because the inner diameter of the pipe is too small, after the grinding head of the manual grinder is inserted into the inner opening of the pipe, it occupies almost all the space in the inner opening. , especially the interior of the pipeline that has just been welded is rough, and workers usually need to spend a lot of effort to control the grinding machine so that the grinding head can quickly and effectively grind the inner mouth. Because workers must hold the manual grinder t...
