In such scheme; The end of described main shaft also is welded with electric machine support, and electric machine support is the L type; The electric machine support bottom is a level tray; Micro-machine is installed on the level tray, and micro-machine is connected with the annular belled position of working beam on main shaft through belt pulley, drives working beam and on main shaft, rotates.
The principle of the utility model device is: when adopting this utility model whirligig cutting large diameter steel pipe groove; Support is stretched in the pipeline; Through the scalable strut this whirligig and steel pipe are fixed; Cutting head is fixed on the clamping head of support working beam, the rotation through working beam drives the cutting torch motion to realize the processing of tube groove.This device is that large diameter steel pipe is fixed, and fixing simultaneously cutting track through rotating cutting torch, guarantees that the cutting datum mark is constant, makes that the tube groove of cutting is level and smooth, superior in quality.
The main beneficial effect of the utility model is:
1, simple in structure, easy to use, can effectively improve the quality of groove processing.
2, this holder device can be used for the groove processing of the large diameter steel pipe that caliber 350 to 700mm, quality should not change greatly.
3, this whirligig can use repeatedly, realizes the automation of groove processing.
