Combined machine tool for manufacturing hollow shaft

Abstract

The invention belongs to the technical field of combined machine tools, and discloses a combined machine tool for manufacturing a hollow shaft. The combined machine tool comprises a rack, wherein a cutting mechanism is arranged on the top face of the rack, a connecting block is arranged at the right end of the top face of the rack, a fixing plate is fixedly mounted on the left side face of the connecting block, a lengthening plate is fixedly mounted in the middle of the fixing plate, and a first positioning shaft and a second positioning shaft are fixedly mounted on the front side face and the rear side face of the lengthening plate respectively. According to the combined machine tool, a connecting wire harness is powered off through a control box, then an electromagnet loses magnetism, and at the moment, a first push-out spring and a second push-out spring which are in a compressed state can push a cutting knife and a movable frame to make contact with a raw material respectively under the action of elastic force; and during cutting, a roller and the cutting knife position the space, in the hollow shaft, of the lengthening plate, so that shaking of the lengthening plate is avoided, radial run-out caused by shaking of the lengthening plate during cutting can be avoided, and the machining precision of the device is improved.

Description

technical field [0001] The invention belongs to the technical field of combined machine tools, in particular to a combined processing machine tool used in the manufacture of hollow shafts. Background technique [0002] Combination processing machine tool refers to a special machine tool composed of serialized and standardized general-purpose parts and a small number of special parts. It is widely used in mass or mass production. One or several processes for one or several similar parts Processing has a high degree of automation, and the hollow shaft needs to use a combined processing machine tool to cut raw materials during production. [0003] When the existing combined processing machine tools are in use, most of them use triangular chucks to process the raw materials, but when the hollow shaft is processed, most of them are divided into left and right sections for processing, so it is necessary to install and clamp the raw materials twice. To reduce the time required for...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a combined processing machine tool used in the manufacture of hollow shafts to solve the problem of low machining accuracy of the device caused by the radial runout of the longer cutting knife in the above-mentioned background technology when cutting. When the inner wall of the hollow shaft is scratched, the processing quality of the device is reduced and it is not convenient to clean the cutting debris, resulting in low production efficiency.
