Axial double helicoid semi-automatic milling machine

Abstract

The invention discloses an axial double-helix-surface semi-automatic milling machine which is used for machining a helix end surface shaft. The machine comprises a horizontal machine body, a horizontal sliding table, a profiling rotating mechanism, a rapid propping mechanism and a double-cutter milling mechanism, wherein the horizontal machine body can be arranged on a workshop working table; the horizontal sliding table is arranged on the horizontal machine body and can longitudinally slide relative to the horizontal machine body; the profiling rotating mechanism is arranged at one end of the horizontal sliding table; a rapid elastic locking clamp installed at the main shaft end of the profiling rotating mechanism is used for clamping the shaft end of a workpiece to be machined; the axial displacement of the workpiece to be machined is determined when a profiling cam ring installed on the periphery of the main shaft end and the main shaft rotate simultaneously; the rapid propping mechanism is installed at the other end of the horizontal sliding table; a movable propping tip is used for propping against the shaft tail of the workpiece to be machined; and the double-cutter milling mechanism is arranged at the lateral upper part of the horizontal machine body; double-axis milling cutters of the double-cutter milling mechanism correspond to the middle part of the workpiece to be machined and are used for simultaneously milling the two same axial helix surfaces of the workpiece. By virtue of the axial double-helix-surface semi-automatic milling machine, the cost on product machining is lowered, and the consistency and the reliability of a product are well controlled.

Description

technical field [0001] The invention belongs to the technical field of automation, and relates to the processing technology of instrument parts, in particular to precision processing equipment for axial double-helix end faces. Background technique [0002] The workpiece to be processed, the helical end shaft such as figure 1 As shown, there are two identical helicoids with an axial distance of 12mm. The intersection line between the helicoid and the shaft cylinder is a standard helix, which is divided into left-handed and right-handed. The right helical plane B is symmetrical to the plane passing through the intersection line. The shaft is used for the production of angular displacement sensors. The 12mm cylinder of the shaft corresponds to a fixed induction coil. The rotation of the shaft changes the area of ​​the cylinder corresponding to the coil, resulting in a change in the inductance parameter induced by the coil, which is proportional to the rotation angle. certain ...
