Rolling mill stand boring machine

Abstract

The invention relates to the field of boring machines, in particular to a rolling mill stand boring machine. The rolling mill stand boring machine comprises a boring head mechanism, a workbench and a machine body, wherein the workbench can move on the machine body, a protective cover is arranged on the machine body, the boring head mechanism is fixed on the machine body and comprises eight boring heads, shafts III, shafts II and a shaft I, the boring heads correspond to plum blossom holes of a rolling mill stand in a one-to-one mode, one boring head is arranged on each shaft III, every two shafts III are linked with one shaft II through gears, the four shafts II are linked with the shaft I through gears, the shafts III and the shafts II are distributed symmetrical to the shaft I, a boring tool is arranged on each boring head, the boring tools are distributed according to fixed angles, and the boring tools on the same diagonal line are distributed symmetrical to the axial center of the shaft I. By the adoption of the scheme, precision machining of the eight semicircular plum blossom holes of the rolling mill stand is achieved.

Description

[0001] technical field [0002] [0003] The invention relates to the field of boring machines, in particular to a rolling mill frame boring machine. [0004] Background technique [0005] The Sendzimir rolling mill accounts for more than 90% of the stainless steel rolling in the world. It is one of the best rolling mills in the world and has been widely used by countries all over the world. The rolling mill frame is one of its most important parts, and the processing accuracy of the "8 semicircular quincunx holes" of the rolling mill frame is the main bottleneck restricting its accuracy. At present, domestic processing uses floor boring machines and special tooling to process single holes one by one. However, since the 8 semicircular quincunx-shaped holes of this part are deep holes and the machining accuracy of the holes is high, there are strict requirements on the relative positions, which brings great difficulty to the processing and low processing efficiency. ...
