Abstract

The invention discloses an internal spiral cutting device comprising a workpiece synchronous rotation power system, a workpiece synchronous feed system, and a tool thread whirling system. The workpiece synchronous rotation power system is characterized in that on the basis of a lathe, a headstock is used as a power source; a gear, a universal joint and splines form a power transmission part; the lathe head is synchronously and rotationally conveyed to an upper stator fixture on a middle carriage. The workpiece synchronous feed system is characterized in that the upper stator fixture is mounted on the carriage of the lathe; when a thread feeding handle of the lathe is closed, the upper stator fixture can be led forward according to a set lead. The internal spiral cutting device has the advantages that when a stator is used as a reference, namely a cutter is in spiral curve cutting movement, an inner cavity is cut; an eccentric value is read through graduation, spiral eccentric precision is guaranteed, and fixation of the two ends of a tool bar ensures concentricity of cut spirals and turning precision; the internal spiral cutting device is applicable to cutting whole bores in solid round bars.

Description

technical field [0001] The invention relates to an internal helical cutting device. Background technique [0002] At present, the manufacturing of the spiral inner cavity of the stator of the all-metal screw pump is a worldwide problem. The current general inner cavity is pressed and formed with stainless steel plates to fill the corresponding filler and then lined to the inner wall of the steel pipe. There are manufacturers in our country who have proposed to use solid round steel for integral inner hole cutting and forming. But there are basically no such products on the market. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an internal helical cutting device that achieves internal cavity cutting when the stator is used as a reference object, that is, the cutterhead is performing a helical curve cutting movement. [0004] The present invention is realized through the following technical solutions: an interna...
