Abstract

The utility model relates to a multipurpose lathe tool belongs to the machining field, the machining of various spare parts of mainly used. A multipurpose turning tool is mainly used for machining an inner hole, an inner spherical surface, an inner end surface and an outer circle. The manufacturing method is simple, raw materials are subjected to heat treatment after turning a cutter blank by using a lathe, are subjected to linear cutting and are milled to form the shape, the main deflection angle is 93 degrees, the auxiliary deflection angle is 52 degrees, the front angle is 5 degrees, the excircle and the rear angle are ground to meet the requirements by using an excircle grinder or a tool, and then the redundant part of the cutter bar is ground according to the machining size requirement so as to prevent the interference when an inner hole is turned. The blade is installed, the front tool face of the blade is close to the center of the cutter rod, so that the interference of the lower part of the cutter rod is avoided, the cross section of the cutter rod can be large enough, and the rigidity of the cutter rod is improved. The multipurpose turning tool is wide in application, simple in structure, capable of reducing tool interference and suitable for machining inner spherical surfaces and inner end surfaces with small curvature and conventional inner holes, outer circles and end surfaces.

Description

Multipurpose lathe tool
Technical Field
The utility model relates to a multipurpose lathe tool belongs to the machining field.
Background
As is known, in the practice of machining production, a turning tool is an important tool in cutting, and one of the most widely used tools, namely a common lathe, an advanced numerical control lathe and a machining center, needs to be turned to complete cutting. The lathe tool kind is more, including excircle lathe tool, hole lathe tool, threading tool, cut off the lathe tool and take shape the lathe tool etc. and the spare part that the structure is complicated needs multiple lathe tool sometimes in the course of working, often the lathe tool need be filled with to the knife rest, still need change in the course of working, and the processing auxiliary time is long can appear, influences productivity ratio's the condition. According to the experience of various lathe tool structures and processing requirements, a multipurpose lathe tool is designed for processing an inner spherical surface and an inner end surface with small curvature and processing an inner hole, an outer circle and an end surface in a conventional mode, and the multipurpose lathe tool is good in effect and worthy of popularization and application through practical production and use.
Disclosure of Invention
A multipurpose lathe tool, a serial communication port: the method has the advantages of wide application, simple structure and manufacturing method, capability of meeting the requirement of multiple purposes, and suitability for processing inner spherical surfaces and inner end surfaces with small curvature and conventional inner holes, outer circles and end surfaces.
In order to ensure that the cutting process is carried out smoothly and that an acceptable working surface is obtained, the cutting portion of the tool used must have a reasonable geometry. The tool angle is an important parameter for determining the geometry of the cutting portion of the tool. Cutter angle mainly has main declination, vice declination, the anterior angle, the relief angle etc, self-control multipurpose lathe tool, in order to satisfy the multipurpose requirement, optimize the cutter angle, main declination 93 °, vice declination 52, the turning effort is concentrated on the tool bit, the vibration trend is little, make it can the turning shaft shoulder, interior sphere and interior terminal surface that the camber is little, the anterior angle 5, belong to the negative anterior angle lathe tool, improve the atress situation and the heat dissipation condition of cutting part, can improve cutting edge intensity and shock-resistant ability, in order to satisfy thick, the fine-processing size precision requirement, according to work piece material performance, use tool grinds the coping relief angle, can promote the cutter performance.
Drawings
FIG. 1 is a schematic view of a multipurpose lathe tool
In the figure, 93 ° is a main declination, 52 ° is a sub declination, and 5 ° is a rake angle.
Fig. 2 is a state diagram of the multipurpose turning tool in use, which is a state diagram of the multipurpose turning tool for processing an inner spherical surface and an inner end surface with small curvature.
Detailed Description
The multipurpose lathe tool is suitable for a numerical control or common machine tool, raw materials are subjected to heat treatment after turning a tool blank, the shape is cut in a linear mode and milled, a main deflection angle of 93 degrees, an auxiliary deflection angle of 52 degrees and a front angle of 5 degrees are guaranteed, an excircle is ground or an excircle and a rear angle are ground by using an excircle grinder or a tool to meet requirements, tool interference can be reduced, multipurpose requirements are met, the multipurpose lathe tool needs to be subjected to nitriding treatment after being machined, the surface hardness and the corrosion resistance are improved, and the effect is good through practical production and.
