Machine tool for processing super long workpiece

Abstract

The invention relates to a machine tool for machining overlong workpiece, which comprises a workpiece machine bed and walking machine bed, which are parallel arranged, wherein the workpiece machine bed has head box and tail box, while the head box is arranged with power cutter, and the head box and the tail box are independently mounted with head box driving motor and tail box driving motor, while the main axle is the hollow axle; the hollow axle is rotated by the main axle motor; the head box driving motor and the tail box driving motor drive the head box and the tail box moves on the track quickly; the walking bed is arranged with one walking table whose two sides are mounted with blade support slide plate and the grinding slide plate with grinder. The invention can complete the processes as grinding, milling, drilling, and drawing at one time, without adjusting workpiece. And the coaxial accuracy between outer round of workpiece and the central axle of inner hole are confirmed.

Description

1. Technical field: [0001] The invention relates to a machine tool used in the field of mechanical processing, in particular to a machine tool used for processing super-long workpieces. 2. Background technology: [0002] Machine tools are commonly used mechanical processing equipment. At present, there are many types of machine tools. They are divided into lathes, milling machines, grinders, etc. according to their processing methods. The process is processed separately on a variety of integrated machine tools. The workpiece and tool holder of the integrated machine tool are placed on a machine bed. Therefore, the processed workpiece is limited by the outer diameter and length of the workpiece, and the length is less than 6 meters. Hydraulic cylinders can be machined on one-piece machines. The processing procedures of the two main components of the hydraulic cylinder can be divided into: 1. Processing of the hydraulic cylinder body: that is, rough turning for inner hole ali...

AI Technical Summary

Problems solved by technology

However, although the current processing machine tools have a parallel side-by-side separation of the workpiece bed and the walking table bed, but because the headstock is fixed, the length of the workpiece to be processed is limited by the bed, and only one process can be processed on the workpiece. Turning, grinding, milling, drilling of the outer diameter of the workpiece and turning, reaming, and extrusion of the inner hole cannot be completed on one machine tool at the same time

Especially for processing super-large workpieces (cylinders) with a length of more than 6 meters, because of their large volume and weight, it is difficult to unload and align them during processing. The concentricity of bit tolerance is difficult to control, not only the work efficiency is low, but the accuracy cannot be guaranteed, especially the accuracy requirements of the coaxiality of the outer circle of the workpiece and the inner thread of the workpiece end and the center line of the inner hole cannot be guaranteed at all.
