Description
Technical field
The present invention relates to machine components screw thread process technical field, be specifically that a kind of turning adds
The device of work screw thread and processing method.
Background technology
Turnery processing screw thread is to use forming threading tool to carry out turnery processing, and its threading tool is cut
The shape cutting part should be consistent with the axial cross section of screw thread.During turning, workpiece every revolution,
Lathe tool must vertically move a helical pitch (single thread: helical pitch=pitch；Double thread: lead
Journey=2 × pitch), just can process correct screw thread.Processing mode is commonly used in thread turning to be had directly
Enter method, angular feed and layered cutting method three kinds:
Straight method cutting thread.During cutting thread, after trial cut checks that workpiece, pitch meet the requirements,
Radial and normal to axis of workpiece feed, repeatedly, until screw thread car is good.This method for turning
Thread form is more accurate.Owing to lathe tool two-edged cuts and chip removal is smooth simultaneously, stress is big, and lathe tool is easy
Abrasion, chip can scratch thread surface.
Angular feed cutting thread.When workpiece pitch is more than 3mm, general employing angular feed car adds
Work screw thread, angular feed is that lathe tool threadingly thread form side makees axial feed while radial feed,
Complete the processing of screw thread through repeatedly feed, finally use straight method penetration of a cutting tool, it is ensured that the thread form of screw thread
The precision at angle.
Left and right feed method.At engine lathe, this method is to control screw thread car with cross slide scale
The vertical feed of cutter, controls the fine feed about lathe tool with the scale of upper slide rest.When screw thread connects
When being closely cut into, whether nut to be used, external thread gauge or three needle check thread sizes and machining accuracy
Qualified.
The method for turning of three of the above screw thread, except straight method cutting thread, (cutting force is big, cutter is easy
Damage) outside work efficiency is higher, the method for turning work efficiency of other two kinds of screw threads is relatively low.Particularly process
During the screw thread of big pitch, owing to machining surplus is relatively big, work efficiency is lower, the technical ability to turner
Require higher.
Therefore, need the device of a kind of turnery processing screw thread badly, to improve the processing of steep-pitch thread
Efficiency and machining accuracy, and reduce in operating process the technical ability to turner.
Summary of the invention
For defect present in prior art, it is an object of the invention to provide a kind of turning and add
