Problems solved by technology

[0003] For threads with small nominal diameter, long processing length and poor workpiece rigidity, it is difficult to clamp the workpiece during processing, the thread cutting is not stable, and the workpiece is difficult to maintain a stable state, etc., resulting in bending deformation of the axis of the external thread of the slender rod and irregular thread profile. , chaotic teeth and other problems, the material of the external threaded part of the slender rod has good plasticity and toughness, but poor hardness
In addition, if the threaded part is located in the middle of the slender shaft, due to the small diameter and poor rigidity of the workpiece, a large deformation will occur during the cutting process and the machining cannot continue

Abstract

The invention discloses a turning device for a long and thin threaded shaft. The turning device for the long and thin threaded shaft is arranged on a large carriage of a lathe and comprises a base, a guide sleeve, a telescopic sleeve, a tool reset ring, thread length control mechanisms and tool assemblies. The turning device has the advantages that scales are arranged on the outer circle surface of the long and thin shaft close to a shaft ring so that the length value of threads to be turned can be accurately adjusted by adjusting the axial positions of adjusting screw sleeves; three sets of turning tools which are uniformly distributed in the circumferential direction are arranged so that the deformation of the threaded shaft in the turning process can be reduced, and the machining quality can be guaranteed; an inclined surface A and an inclined surface C which can make contact with each other or can be separated from each other are arranged so that finish machining of the threads can be accurately realized, and the situation of tool breakage can be effectively prevented; and the tool reset ring is arranged so that the three sets of turning tools can contract towards the center at the same time, and therefore the operation can be rapid and convenient.

Description

[0001] This application is a divisional application of a Chinese invention patent application with an application date of September 29, 2016 and an application number of 201610860901.7. The invention name is a turning method for a slender threaded shaft. technical field [0002] The invention relates to the technical field of machining, in particular to a turning device for a slender threaded shaft. Background technique [0003] For threads with small nominal diameter, long processing length and poor workpiece rigidity, it is difficult to clamp the workpiece during processing, the thread cutting is not stable, and the workpiece is difficult to maintain a stable state, etc., resulting in bending deformation of the axis of the external thread of the slender rod and irregular thread profile. , disordered teeth and other problems, the material of the external threaded part of the slender rod has good plasticity and toughness, but poor hardness. In addition, if the threaded part ...
