A CNC deep hole drilling machine tool for processing group holes on the outer circle of rollers

Abstract

The invention relates to a numerical-control deep hole drill machine tool for processing group holes in an outer circle of a roller. The numerical-control deep hole drill machine tool is characterized by comprising a hole drilling movement mechanism, a transverse shifting movement mechanism, a work-piece dividing movement mechanism and an oil supply filtering mechanism; the hole drilling movement mechanism comprises five groups of drilling units and five groups of numerical-control sliding tables; the transverse shifting movement mechanism comprises a tool body, a lead screw transmission assembly, a large carriage and a servo motor, wherein the tool body is mounted on the ground; the lead screw transmission assembly driven by the servo motor is mounted on the tool body and connected with the large carriage; the work-piece dividing movement mechanism comprises a workbench, a driving rotating device, a driven rotating device, a work-piece, a carrier roller, a transverse shifting assembly and another servo motor; the oil supply filtering mechanism consists of a high-pressure oil supply device and a filtering device. With the adoption of the numerical-control deep hole drill machine tool, the processing efficiency and processing precision, in particular the degree of finish of processed holes, are improved; processed deep holes are effectively prevented from floccule hanging on a wall with the extremely high surface finish, and therefore, the portability that a hole of the roller is blocked can be greatly reduced, the use efficiency is improved, and the maintenance cost can be decreased.

Description

technical field [0001] The invention relates to the field of drilling machines in the papermaking machinery industry, in particular to a numerically controlled deep hole drilling machine for processing a group of holes on the outer circle of a roller. Background technique [0002] At present, the domestic papermaking machinery industry uses twist drills to process the holes on the outer circle of the rollers, but the efficiency is too low, and the finish is not high, which greatly reduces the utilization rate of the rollers on the papermaking machinery. Nowadays, in the papermaking machinery industry, in order to ensure the strength of the roller, the requirements for the wall thickness of the roller are getting higher and higher, especially the vacuum press roller, the wall thickness reaches more than 70mm, and the processing aperture aspect ratio is more than 35. It is difficult to guarantee the straightness and surface finish of the processed holes. For the gun drill use...
