High-efficiency small and deep hole production machine tool

Abstract

The invention discloses a high-efficiency small and deep hole production machine tool. The high-efficiency small and deep hole production machine tool comprises a machine tool body. A transmission mechanism is arranged on the machine tool body and connected with drill hole milling cutters which are horizontally arranged. The included angle between every two adjacent drill hole milling cutters is 90 degrees. The transmission mechanism is movably connected with the machine tool body and can perform rotary motion around the axis of the transmission mechanism. Four workpiece feeding mechanisms are arranged at the periphery of the transmission mechanism. Each workpiece feeding mechanism corresponds to the corresponding drill hole milling cutter. Each workpiece feeding mechanism is connected with the machine tool body through a slide rail. By means of the deep hole production machine tool, deep hole machining can be conducted on multiple workpieces at the same time; meanwhile, when deep holes of different dimensions need to be machined in the workpieces, the process can be achieved by rotating the transmission mechanism to change the movement direction without replacing the milling cutters; workpiece machining is accelerated, and in addition, the time of replacing the milling cutters is omitted; and work efficiency is greatly improved.

Description

technical field [0001] The invention relates to a production machine tool, in particular to a high-efficiency small deep hole production machine tool. Background technique [0002] Deep hole processing machine tools mainly include horizontal deep hole drilling and boring machines, vertical deep hole drilling and boring machines, deep hole gun drills, and deep hole deep hole stringer mills. The deep hole processing machine tool adopts two processing methods according to the length of the workpiece: the short workpiece is oiled by the oiler and hydraulically tightened; the long workpiece is oiled by the tail of the boring bar and clamped by the four-jaw chuck. The oil feeder adopts an innovative main shaft structure, which greatly improves the load-bearing performance and the rotation accuracy is higher. The bed guide rail adopts double rectangular guide rail suitable for deep hole processing machine tools, with large bearing capacity and good guiding precision; the guide rai...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the existing processing machine tools can only process a single workpiece with a single size of deep hole. For a workpiece that needs to process multiple sizes of deep holes on a workpiece, it is necessary to change the size of the milling cutter, which is a waste of time. , which reduces the work efficiency, the purpose is to provide a high-efficiency small deep hole production machine tool, which can perform deep hole processing on multiple workpieces at the same time. It can be realized by using the direction of the transmission mechanism to rotate and move, which not only speeds up the processing rate of the workpiece, but also saves the time for changing the milling cutter, greatly improving the work efficiency
