Abstract
The invention provides a spindle used for grinding positioning. According to the technical scheme, the spindle used for grinding positioning comprises a spindle body, wherein an expansion jacket which surrounds the spindle body is arranged on the spindle body, the expansion jacket is hollow, and the two ends of the expansion jacket are fixed on the spindle body. The spindle used for grinding positioning has the advantages that the clamping accuracy is high, the spindle can be assembled and disassembled conveniently, workpiece machining accuracy and working efficiency can be improved, and the labor intensity of operator can be relieved.
Description
Technical field
The present invention relates to be a kind of for all kinds of specification roller grinding time location use mandrel with adding the grinding location of holding, belong to mechanical manufacturing field.
Background technology
In the prior art, known technology is that grinding refers to and uses abrasive material, the processing method of excess stock on grinding tool excision workpiece.Grinding is one of widely used cutting working method.When the various roller class of grinding part, this type of part need to be equipped with after mandrel processing excircles on grinding machine.As casting conductance roller for continuous casting installation for casting, deflector roll endoporus, cylindrical center line axiality require high.For meeting its axiality requirement, in process, need according to the hole of roller size, after accurately clamping deflector roll, the employing mandrel carries out grinding processing method, the axiality requirement of cylindrical and endoporus after the guarantee grinding.Therefore, must accomplish that between endoporus and mandrel, gapless coordinates.Adopt conventional mandrel, be difficult to solve mandrel and endoporus gapless and the simple load and unload problem of mandrel simultaneously.This is the existing weak point of prior art.
Summary of the invention
Purpose of the present invention is exactly for the existing deficiency of prior art, and the technical scheme of a kind of grinding location with mandrel is provided, and the location of this scheme is high with the mandrel clamp precision, and the mandrel mounting or dismounting are convenient, both can improve machining accuracy and the work efficiency of part, reduce again operator's labour intensity.
This programme is achieved by the following technical measures: a kind of grinding location mandrel, comprise axis body, the characteristics of this programme: described axis body is provided with the expansion overcoat around axis body, and described expansion overcoat is hollow, and the two ends of expansion overcoat are fixed on axis body.
One end of described expansion overcoat is fixed on axis body by nut, and the screw thread mated with nut is arranged on axis body, and the other end of expansion overcoat is bolted on axis body.
Be provided with annular protrusion on described axis body, described being bolted on annular protrusion.
Described bolt is hex bolts.
The two ends of described expansion overcoat are provided with O-ring seals.
Described expansion overcoat is communicated with an oil pump.
The beneficial effect of this programme can be learnt according to the narration to such scheme, because the arranged outside at axis body in this scheme has the expansion overcoat, during use, can be by expansion overcoat rising, make expansion overcoat and inner bore of part to be processed combine closely, realize the hi-Fix of part and step up; One end of expansion overcoat is fixed on axis body by nut, and the other end of expansion overcoat is bolted on axis body, while having avoided the expansion overcoat to expand, breaks away from axis body; The two ends of expansion overcoat are provided with O-ring seals, play sealing function, the expansion overcoat are shielded simultaneously, and avoiding has too much friction with axis body; The expansion overcoat is communicated with an oil pump, can give the oiling of expansion overcoat, and the overcoat that makes to expand expands.
As can be seen here, the present invention compared with prior art, has outstanding substantive distinguishing features and significant progressive, and the beneficial effect of its enforcement is also apparent.
The accompanying drawing explanation
The structural representation that Fig. 1 is the specific embodiment of the invention.
In figure, 1 is axis body, and 2 is bolt, and 3 is oil pump, and 4 is the expansion overcoat, and 5 is the O RunddichtringO, and 6 is nut, and 7 is annular protrusion.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, below by a specific embodiment, and, in conjunction with its accompanying drawing, this programme is set forth.
By accompanying drawing, can find out, mandrel is used in the grinding location of this programme, comprises axis body 1, and described axis body 1 is provided with the expansion overcoat 4 around axis body 1, and described expansion overcoat 4 is hollow, and the two ends of expansion overcoat 4 are fixed on axis body 1.
One end of described expansion overcoat 4 is fixed on axis body 1 by nut 6, and the screw thread with nut 6 coupling is arranged on axis body 1, and the other ends of outer 4 covers that expand are fixed on axis body 1 by bolt 2.Be provided with annular protrusion 7 on described axis body 1, described bolt 2 is fixed on annular protrusion 7.Described bolt 2 is hex bolts.
The two ends of described expansion overcoat 4 are provided with O-ring seals 5.Described expansion overcoat 4 is communicated with an oil pump 3.
The present invention is not limited in the above-mentioned specific embodiment, and the variation that those of ordinary skills make in essential scope of the present invention, remodeling, interpolation or replacement also should belong to protection scope of the present invention.
