Abstract
The utility model discloses a shell of a high-speed live center. The shell consists of a shaft shell and a shell taper shank which are in an integral structure, wherein the shell taper shank is a morse taper shank; and the tail end of the shell taper shank is provided with a plug. The shell consists of two parts, i.e., the shaft shell and the shell taper shank, and is designed into an integral structure; a plurality of bosses are arranged in a cavity of the shaft shell; and the shell can be used for a mechanism for positioning a bearing and mounting a fixing bearing, has a simple structure and is long in service life.
Description
Technical field
The utility model relates to a kind of high speed live center that is used on the numerical control machining center, a kind of specifically housing of high speed live center.
Technical background
At present; The live center that adopts on the market mainly comprises following structure: centre head, tail spindle, housing, housing taper shank etc.; Between tail spindle and housing, be provided with some groups of bearings; Because internal bearings has played crucial effects in the live center course of work; Therefore the quality of case design has influence on the precision and the serviceability of live center too; Yet the live center behaviour in service of using at present is following: because the unreasonable play of internal bearings discontinuity equalization and existence that causes of live center case design makes the rotating accuracy of live center itself satisfy not machining accuracy degree needs, and cause that parts are easy to wear, precision is lower, service life is short, stock-removing efficiency is low, thereby make the production cost height.
The utility model content
The purpose of the utility model is for the deficiency that solves the problems of the technologies described above, and a kind of housing of high speed live center is provided, and is simple in structure, long service life.
The utility model is the deficiency that solves the problems of the technologies described above; The technical scheme that is adopted is: a kind of housing of high speed live center, to form by axle housing and housing taper shank, and axle housing and housing taper shank are structure as a whole; The housing taper shank is a Morse taper shank, is provided with plug at the end of housing taper shank.
Said housing taper shank, the tapering of its Morse taper shank are 1:19.
Said housing taper shank is a hollow core structures.
Said housing taper shank, its end is provided with the taper shank boss.
Be respectively equipped with one-level boss, secondary boss and three grades of boss on the inner chamber of said axle housing.
The beneficial effect of the utility model is: the utility model is made up of axle housing and housing taper shank two parts; And adopt the integrative-structure design, through at the axle housing inner chamber a plurality of boss being set, the mechanism that can be used for location bearing and install and fix bearing; Simple in structure, long service life.
