Abstract
The utility model provides a technical scheme of a mandrel for grinding positioning. The mandrel of the scheme comprises a mandrel body, an outer hollow expansion sleeve around the mandrel body is arranged on the mandrel body, and two ends of the outer expansion sleeve are fixed on the mandrel body. The mandrel for grinding positioning is high in clamping accuracy and convenient to assemble and dissemble, so that the machining accuracy and the work efficiency of a part can be improved, and the labor intensity of an operator is reduced.
Description
Technical field
The utility model relates to a kind of for all kinds of specification roller grinding time location with add the grinding location mandrel of holding, belong to mechanical manufacturing field.
Background technology
In the prior art, known technology is that grinding refers to 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 tube kind part of grinding, 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 hole of roller size, after accurately clamping deflector roll, employing mandrel carries out grinding processing method, the axiality requirement of cylindrical and endoporus after 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
The purpose of this utility model 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 mandrel clamp precision, and mandrel mounting or dismounting are convenient, machining accuracy and the work efficiency that both can improve part, reduced again operator's labour intensity.
This programme is achieved by the following technical measures: a kind of grinding location mandrel, comprise axis body, the feature of this programme: described axis body is provided with the expansion overcoat around axis body, described expansion overcoat is hollow, the two ends of expansion overcoat are fixed on axis body.
One end of described expansion overcoat is fixed on axis body by nut, has the screw thread mating with nut on axis body, and the other end of expansion overcoat is bolted on axis body.
On described axis body, be provided with annular protrusion, described is 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 expansion overcoat, during use, can be by expansion overcoat rising, make to expand overcoat and inner bore of part to be processed combined closely, and realizes the hi-Fix of part and steps 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 expansion overcoat to expand, departs from axis body; The two ends of expansion overcoat are provided with O-ring seals, play sealing function, expansion overcoat are shielded simultaneously, and avoiding has too much friction with axis body; 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 utility model compared with prior art, has outstanding substantive distinguishing features and significant progressive, and the beneficial effect of its enforcement is also apparent.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model specific embodiment.
In figure, 1 is axis body, and 2 is bolt, and 3 is oil pump, and 4 is expansion overcoat, and 5 is 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, the grinding location mandrel 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, has the screw thread mating with nut 6 on axis body 1, and the other ends of outer 4 covers that expand are fixed on axis body 1 by bolt 2.On described axis body 1, be provided with annular protrusion 7, 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.
