Compound machine tool for milling end face and boring center hole in oblique guide rail

Abstract

The invention discloses a compound machine tool for milling an end face and boring a center hole in an oblique guide rail. The compound machine tool comprises a base (1), a movable workbench (2), a workpiece positioning device (3), a milling device (4), a drilling device (5), a fixture (6) and a cooling and chip removing device (7), wherein the movable workbench (2) is arranged on the oblique table surface of the base (1); the workpiece positioning device (3) is arranged on the base (1); the chuck (6) is arranged on the movable workbench (2); the cooling and chip removing device (7) is connected with the inner cavity of the base (1). The compound machine tool provided by the invention has the advantages of reasonable structural design, high automation degree, convenience in operation and high working efficiency, end face milling and center hole boring can be realized in sequence, chips, cooling liquid and the like can be easily discharged, a prepared product has high quality, and a plurality of defects in the prior art can be overcome.

Description

technical field [0001] The invention relates to a machining machine tool, in particular to a compound machine tool with high production efficiency, capable of automatic chip removal, automatic cleaning of cutting fluid, and capable of milling end faces and drilling center holes on the same machine tool. Background technique [0002] At present, the processes of drilling the center hole and milling the end face are usually completed on two independent machine tools, or on a lathe. For example, to process a steering knuckle, it is necessary to first mill the end face of the shaft to determine the length, drill the center hole, and then turn around and drill the center hole on the other end face. The two center holes serve as the main benchmarks for subsequent processing. In the prior art, the blank surface is used as the rough reference for both schemes. The workpiece is repeatedly positioned and clamped, and the centering accuracy is poor, which affects the processing quality ...

[0002] At present, the processes of drilling the center hole and milling the end face are usually completed on two independent machine tools, or on a lathe. For example, to process a steering knuckle, it is necessary to first mill the end face of the shaft to determine the length, drill the center hole, and then turn around and drill the center hole on the other end face. The two center holes serve as the main benchmarks for subsequent processing. In the prior art, the blank surface is used as the rough reference for both schemes. The workpiece is repeatedly positioned and clamped, and the centering accuracy is poor, which affects the processing quality of the subsequent process. The workload is large and the degree of automation is high. low, low processing efficiency

Moreover, most of the machine tools for drilling center holes adopt the horizontal axis processing form, and chips, coolant, etc. are not easy to discharge, which affects the processing quality
