Description
Technical field
The utility model belongs to machining equipment technical field, and what is involved is a kind of shaft outer circle magnetically grinding toolings.
Background technique
Magnetically grinding is a kind of new grinding method to grow up on the basis of tradition machinery grinding, and this method uses
Magnetic abrasive is adsorbed on grinding head by magnetic field, and is passed through the relative rotation between grinding head and workpiece and moved back and forth and finally reach
The purpose processed to surface finish, adaptable good, the advantages that processing quality is reliable and stable, therefore in grinding shaft outer circle side
Face is applied.But current magnetically grinding equipment is complex, includes not only magnetically grinding system, further includes a whole set of
The power and transmission mechanism for driving workpiece rotation and axial movement, not only cause at high cost, but also failure rate is higher, is unfavorable for
The popularization and large-scale application of the device.In addition, be permanent magnet as used in magnetically grinding system, although magnetic larger,
But it is extremely difficult to replace abrasive material.
Summary of the invention
The purpose of this utility model is that proposing that one kind for shaft outer circle magnetically grinding tooling, makes the magnetism of shaft outer circle
Grinding can be completed on existing lathe.
Realizing the technical solution of above-mentioned purpose is: a kind of shaft outer circle magnetically grinding tooling, including pedestal, two groups of electromagnetic installings
It sets and a pair of of grinding head, is fixedly installed two pairs of vertical plates on the pedestal, one group of calutron is installed on each pair of vertical plate, every group
One end of iron core is equipped with a through-hole perpendicular to the iron core axis in calutron, and the axis of through-hole is overlapped on two iron cores,
A mounting rod is respectively fitted in two through-holes, the correspondence end of two mounting rods is respectively fitted with a grinding head, the pedestal
It is equipped with multiple mounting holes that can be stably connected with the knife rest mounting base of lathe.
Further, the mounting rod is positioned by jackscrew in the through hole.
Further, in the calutron, magnet exciting coil is DC series excitation coil.
The utility model is mounted in the knife rest mounting base of lathe, when carrying out magnetically grinding to shaft workpiece, first allows vehicle
The grips of bed live workpiece, while are in workpiece between two grinding heads of the utility model, are then turned on two groups of electromagnetism
The power-on switch of device, due to each lead into two groups of calutrons current direction on the contrary, therefore produced by magnetic direction on the contrary,
The magnetic pole presented on two grinding heads is the pole N and the pole S respectively, is given between two grinding heads at this time and launches selected magnetic conductivity mill
Material finally starts lathe, drives workpiece rotation.When workpiece rotation, the workpiece between two grinding heads is i.e. by abrasive lapping.
After the completion of one section of shaft is ground, drives workpiece to do axial displacement by knife rest mounting base, then proceed to the next of grinding work-piece
Section, until completing the grinding of entire shaft.
The utility model simple structure, manufacturing cost is low, be assemblied in the high-precision rotary having on lathe by lathe and
The high-precision magnetically grinding of shaft outer circle can be completed in surge motion control.Again since the magnetic field of two grinding heads is by electromagnetism
Device generates, and therefore, the presence or absence of magnetic field and power can be controlled by adjusting the size of supply electric current, when replacing abrasive material,
The power-on switch that two groups of calutrons need to only be disconnected can make the magnetism on two grinding heads disappear, and abrasive material replacement is easy to.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As Figure 1-Figure 4, the utility model includes 1, two group of calutron of pedestal and a pair of of grinding head 6, is consolidated on pedestal 1
Surely two pairs of vertical plates 2 are provided with, one group of calutron is installed on each pair of vertical plate 2, which includes magnet exciting coil 4 and iron core
3, one end of iron core 3 is equipped with a through-hole perpendicular to the iron core axis in every group of calutron, the axis of through-hole on two iron cores 3
Line is overlapped, and is respectively fitted with a mounting rod 5 in two through-holes, mounting rod 5 is adapted to the through-hole, and mounting rod is in the through hole
It is positioned by jackscrew, the correspondence end of two mounting rods 5 is respectively fitted with a grinding head 6, is additionally provided with multiple mounting holes on pedestal
7, by mounting hole 7, pedestal 1 can be stably installed in the knife rest mounting base of lathe.
Pedestal 1 is the installation pedestal of each component in the utility model, and the component directly connecting with lathe.
Vertical plate 2 is the component for supporting calutron, and two vertical plates are one group, and one group of vertical plate supports one group of calutron,
