Abstract
The utility model relates to a kind of mandrel device for grinding positioning sleeve, grinding machine headstock is provided with front thimble, the grinding machine tailstock is provided with back center, mandrel is installed on lathe by front thimble and back center, folder pearl encapsulation is clamped on mandrel, emery wheel is fixed on above mandrel, grinding machine headstock is provided with driving lever, the internal diameter of outside diameter of mandrel and described positioning sleeve closely cooperates, and mandrel is consistent with the axiality of positioning sleeve, wherein the periphery of mandrel is be with gradient periphery, for playing fixing effect when positioning sleeve is sleeved on mandrel, when machine tool running, folder pearl is stirred by driving lever, thus drive the mandrel grinding on sand being set with positioning sleeve.The utility model structure is simple, because mandrel and positioning sleeve uniformity are better, so the positioning sleeve scaled fine processed, and saving cost.
Description
Technical field
The utility model belongs to grinding fixture field, is specifically related to a kind of mandrel device for grinding positioning sleeve.
Background technology
The product of company nearly thousands of kinds, but the bolt hole dimensions of brake drum is in kind more than 10.Workshop make drill jig, usually a drill jig needs the positioning sleeve of equipped a lot of quantity, and positioning sleeve and positioning sleeve after heat treatment, the grinding allowance stayed is very little, greatly about 0.15-0.2mm..And the cylindrical of positioning sleeve and this mates of drill jig, and adopt the interference fits that dimensional tolerance is less.The excircle dimension of grinding positioning sleeve, dimensional tolerance generally all controls at 0.02 mm.So during grinding positioning sleeve, mandrel size and the shape of the use of Set and Positioning cover are just most important.
Summary of the invention
The purpose of this utility model is to provide a kind of mandrel device for grinding positioning sleeve.This apparatus structure is simple, due to mandrel and positioning sleeve uniformity better, so the positioning sleeve scaled fine processed, better with drill jig body fits.
The technical solution adopted in the utility model: a kind of mandrel device for grinding positioning sleeve, it comprises mandrel, folder pearl, grinding machine headstock, the grinding machine tailstock and emery wheel, grinding machine headstock is provided with front thimble, the grinding machine tailstock is provided with back center, mandrel is installed on lathe by front thimble and back center, folder pearl encapsulation is clamped on mandrel, emery wheel is fixed on above mandrel, grinding machine headstock is provided with driving lever, the internal diameter of outside diameter of mandrel and described positioning sleeve closely cooperates, and mandrel is consistent with the axiality of positioning sleeve, wherein the periphery of mandrel is be with gradient periphery, for playing fixing effect when positioning sleeve is sleeved on mandrel, when machine tool running, folder pearl is stirred by driving lever, thus drive the mandrel grinding on sand being set with positioning sleeve.
The utility model compared with prior art its beneficial effect is: the utility model structure is simple, due to mandrel and positioning sleeve uniformity better, so the positioning sleeve scaled fine processed, and adopt device of the present utility model to save cost, solve positioning sleeve grinding allowance well little, the problem bad with drill jig body fits.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In accompanying drawing: 1-mandrel; 2-presss from both sides pearl; 3-grinding machine headstock; The 4-grinding machine tailstock; 5-emery wheel; 6-front thimble; 7-back center; 8-driving lever.
Detailed description of the invention
As shown in Figure 1, a kind of mandrel device for grinding positioning sleeve, it comprises mandrel 1, folder pearl 2, grinding machine headstock 3, the grinding machine tailstock 4 and emery wheel 5, grinding machine headstock 3 is provided with front thimble 6, the grinding machine tailstock 4 is provided with back center 7, mandrel 1 is installed on lathe by front thimble 6 and back center 7, folder pearl 2 encapsulation is clamped on mandrel 1, emery wheel 5 is fixed on above mandrel 1, grinding machine headstock 3 is provided with driving lever 8, the internal diameter of mandrel 1 external diameter and described positioning sleeve closely cooperates, and mandrel 1 is consistent with the axiality of positioning sleeve, wherein the periphery of mandrel 1 is be with gradient periphery, fixing effect is played during for being sleeved on mandrel 1 when positioning sleeve, when machine tool running, folder pearl 2 is stirred by driving lever 8, thus drive mandrel 1 grinding on sand being set with positioning sleeve.
The course of work: when grinding positioning sleeve, by the endoporus of mandrel through positioning sleeve, the periphery of mandrel, with less gradient, is used for fixing positioning sleeve, and drives the rotation of positioning sleeve, mandrel clamping is on folder pearl, there is centre bore at two of mandrel, and when grinding, the top of grinding machine withstands two centre bore, and folder pearl stirred by the driving lever on grinding machine, band moving mandrel together rotates together with sprocket bit cover, the cylindrical of the positioning sleeve that grinding rotates by the emery wheel rotated.
