Abstract
The invention relates to a centering fixture, which relates to the field of a mechanical auxiliary device, in particular to a centering fixture. The centering fixture comprises a spindle, wherein a clamp body sleeves the spindle, one end of the clamp body is connected with a machine tool head through a plurality of separation sleeves, the other end of the clamp body is connected with a pressing sleeve, and the pressing sleeve is fixed on the spindle through a nut. The centering fixture is high in centering precision, uniform in clamping force, simple in structure and wide in application range; the centering precision of the fixture is not affected after the fixture is used for multiple times, and the economic benefit is high.
Description
Technical field
The present invention relates to assist field, be specifically related to centralizer.
Background technology
An inner ring cam is had in freewheel clutch in engineering machinery, 20 planes are had to be uniformly distributed along the circumference above, these planes directly have influence on the locking of clutch to its deviation of the distance in endoporus or throw off effect, the centering precision of this fixture just made is very high, but present used centralizer also has certain defect on centering precision, make the part centering precision that processes not high, and when part is precision component, the part that can not meet centering precision is then defective, and working (machining) efficiency is low in process, hand labor intensity is large.
Summary of the invention
In order to solve the problem, the invention provides a kind of centering precision high, and clamping force is even, clamp structure is simple, and long service life, repeatedly uses the centering precision of fixture affected centralizer hardly.
Centralizer of the present invention, comprises mandrel, it is characterized in that, described mandrel is socketed with a clamp body, and described clamp body one end is connected with lathe head by some spacers, and the other end is connected with gland, and described gland is fixed on mandrel by nut.
Preferably, clamp body is the cylinder of hollow, described cylindrical outer surface has some clamp body outer surface annular grooves, and internal surface of column between every two clamp body outer surface annular grooves has a clamp body inner surface annular groove.
Preferably, the width of clamp body inner surface annular groove is greater than the width of annular groove on clamp body outer surface.
Preferably, clamp body inner surface has a clamp body inner surface annular groove, clamp body outer surface has two clamp body outer surface annular grooves, and described clamp body inner surface annular groove is between two clamp body outer surface annular grooves, and the width of clamp body inner surface annular groove is the twice of annular groove width on clamp body outer surface.
Centering precision of the present invention is high, and clamping force is even, and clamp structure is simple, and long service life, repeatedly uses the centering precision of fixture influenced hardly.

Detailed description of the invention
Centralizer of the present invention, comprises mandrel 1, described mandrel 1 is socketed with a clamp body 2, and described clamp body 2 one end is connected with lathe head by some spacers 4, and the other end is connected with gland 4, and described gland 4 is fixed on mandrel 1 by nut 5.Clamp body 2 is the cylinder of hollow, described cylindrical outer surface has some clamp body outer surface annular grooves 6, and internal surface of column between every two clamp body outer surface annular grooves 6 has a clamp body inner surface annular groove 7.The width of clamp body inner surface annular groove 7 is greater than the width of annular groove 6 on clamp body outer surface.Clamp body inner surface has a clamp body inner surface annular groove 7, clamp body outer surface has two clamp body outer surface annular grooves 6, and described clamp body inner surface annular groove 7 is between two clamp body outer surface annular grooves 6, and the width of clamp body inner surface annular groove 7 is the twice of annular groove 6 width on clamp body outer surface.
In use, workpiece is socketed on clamp body 2 outer surface, clamp body 2 external diameter and workpiece diameter measure-alike, fastening nut 5, makes clamp body 2 axial compression, in compression process by gland 4, the external diameter distortion of clamp body 2 increases, ID distortion reduces, thus makes workpiece energy blind-mate, can play the effect of precision centering clamping.
Centralizer can also apply the fine finishining with the class part such as gear, ring, sleeve, and clamping force is even, and centering precision is high.
