Detailed Description

The section is an embodiment of the present invention for explaining and explaining the technical solution of the present invention,

the utility model provides a machine fraising device for pipe, includes frock locator 1, scale 2 and jig mechanism 3, frock locator 1 and pipe relatively fixed connection,

frock locator

1 and 2 sliding connection of scale, the one end and the 3 fixed connection of jig mechanism of scale 2, jig mechanism 3 slides and hugs closely on the pipe surface for the pipe through scale 2.

The connecting part of the tool positioner 1 and the scale 2 is provided with a limiting device 4, and the limiting device 4 is used for limiting the sliding of the scale 2.

The tool positioner 1 comprises an outer end face 1-1 and a boss 1-2, the boss 1-2 is arranged in the middle of the outer end face 1-1, the outer diameter of the boss 1-2 is matched with the inner diameter of the guide pipe, a through hole is formed in the outer end face 1-1, and the scale 2 penetrates through the through hole in the outer end face 1-1.

When the tool positioner 1 is arranged on the end face of the guide pipe through the boss 1-2, the through hole on the outer end face 1-1 is parallel to the axis of the guide pipe, so that the scale 2 is parallel to the axis of the guide pipe.

The jig mechanism 3 comprises a lining 3-1, a plurality of drill holes are formed in the lining 3-1, a jig 3-2 is arranged on each drill hole, and the lining 3-1 is perpendicular to the axis of the pipe.

Another embodiment of the present invention is described below with reference to the drawings.

According to the technical scheme, the end head and the pipe body of the guide pipe on the machine are tooling fixing points, the position of a drill jig is determined through a ruler, and the drill jig is fixed and reamed through a drill jig bolt, so that the purpose of precisely reaming the guide pipe on the machine is achieved.
