Lathe adapter used for fine bar processing

Abstract

The invention relates to a lathe adapter used for fine bar processing, the left end of an adapter (4) is connected with an fine bar workpiece (3), the right end is connected with a lathe center (5), the left end of the adapter (4) is provided with a trapezoid bulge (6), the right end is provided with an inner stepped hole (10) and an outer stepped hole (11) which have unequal diameters, the surface of the trapezoid bulge (6) is provided with a cone-shaped groove (8), the bottom of the cone-shaped groove (8) is further provided with a cylindrical groove (9), and the joint of the inner stepped hole (10) and the outer stepped hole (11) is provided with a slope (7). Compared with the prior art, the adapter (4) is installed between the fine bar workpiece (3) and the lathe center (5), not only can more firmly fix the fine bar workpiece (3) but also can be skillfully connected with the lathe center (5), overcomes the vibrating problem during processing the fine bar workpiece (3) accordingly, and effectively improves the processing accuracy of the fine bar workpiece (3).

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and relates to a lathe adapter, in particular to a lathe adapter used for processing thin rods. Background technique [0002] In the process of lathe processing, it is often necessary to process some thin rod parts. Generally, for thin rod workpieces with shorter length and more uniform diameter, the machining accuracy of lathe can be better guaranteed. However, in some special cases, for example, it is necessary to process thin rod workpieces with small diameter and long length. During the working process of the lathe, it is often easy to tremble, which will directly affect the processing of thin rod workpieces. Accuracy, resulting in large processing errors of thin rod workpieces, directly affects the quality of products, thus causing large economic losses to production and processing. Contents of the invention [0003] The object of the present invention is to provide a lathe ...
