Supporting mechanism for steel pipe internal grinding

Abstract

The invention relates to the technical field of metal pipe machining equipment, in particular to a supporting mechanism for steel pipe internal grinding. The supporting mechanism comprises a pipe body, a main driving shaft and a grinding wheel; the main driving shaft is axially and fixedly connected with a rotating shaft of a high-speed motor; the grinding wheel is located in the pipe body; the pipe body is internally provided with a first transverse driving pipe; and the main driving shaft is inserted into the first transverse driving pipe and is movably connected with the internal wall of the first transverse driving pipe. According to the supporting mechanism for the steel pipe internal grinding, the high-speed motor is connected with the grinding wheel by driving shafts in driving pipes which communicate mutually, and the height of the connecting end of the grinding wheel is changed freely by employing a second longitudinal driving shaft formed by an upper rotating shaft and a lower rotating shaft, so that the mounting height of the grinding wheel can be adjusted, the application scope of the diameter of the grinding wheel is widened substantially, and the service life of the single grinding wheel is prolonged substantially.

Description

technical field [0001] The invention relates to the technical field of metal pipe processing equipment, in particular to a support mechanism for internal rounding of steel pipes. Background technique [0002] In the internal grinding equipment for metal pipe workpieces, the existing technology is to connect the motor and the grinding wheel through the long transmission shaft, and the motor drives the long transmission shaft to rotate to realize the rotation of the grinding wheel, and to grind the inner wall of the metal pipe workpiece. , in order to achieve a better grinding effect, the speed of the motor is usually higher, that is, the working state of the long drive shaft and the grinding wheel is high-speed rotation during the grinding process, and the long drive shaft rotates at high speed, and the long drive shaft and the support bushing The bearings between them are very vulnerable to damage, and the entire support mechanism needs to be replaced, which is expensive and...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: in order to solve the problems existing in the above-mentioned background technology, provide an improved support mechanism for internal grinding of steel pipes, and solve the problem that the support sleeves currently on the market cannot adapt to grinding wheels with different diameters. Moreover, once the grinding wheel wears less than the specified size, it cannot be used, which is a very wasteful problem
