Abstract

The invention provides an excircle machining mechanism which can machine overlength workpiece with low energy consumption, long service life and high machining precision and comprises an inner cyclone milling head and a primary motor connected with the cyclone milling head to drive for rotation around the y axis. The inner cyclone milling head is rotatably connected on a supporting seat. The primary motor and the supporting seat are fixed on a slide board which is in sliding connection with the engine base along the z axis direction vertical to the y axis. The slide board is connected with the transmission mechanism driving the slide board to slide along the z axis. An engine base is arranged on an x axis supporting plate moveable along the x axis direction vertical to the y axis. When processing the excircle, the workpiece is stationary, the inner cyclone milling head rotates at high speed (around y axis), the workpiece extending into the inner cyclone milling head is stationary and meanwhile inner cyclone milling head translates on two directions (x axis and z axis directions) vertical to the rotor axis, thus machining the excircle of the workpiece.

Description

technical field

[0001] The invention relates to the technical field of machining, and belongs to an outer circle cutting machine, in particular to a non-rotating outer circle machining mechanism for workpieces. Background technique

[0002] Most of the existing cylindrical processing machine tools adopt a processing method in which the tool is stationary and the workpiece is rotating. The spindle speed of ordinary machine tools is about 1000 rpm, which not only consumes a lot of energy, but also has a great impact on the life of the machine tool. Secondly, when ordinary lathes are cutting at high speeds, the mechanical vibration generated is relatively large, which will inevitably affect the workpiece. Accuracy and surface roughness have a great influence. If the workpiece is super long (such as the main railing rope of a cross-sea bridge) or super large (such as the crankshaft of a large marine diesel engine, which is tens of meters long and weighs dozens of tons), ordinar...
