(2) emery wheel reconditioning method: grinding machine carries out grinding to the seamless steel pipe internal wall defective in adopting, being about to seamless steel pipe is fixed on the equipment, corundum wheel is arranged on the mill bar, the mill bar stretches into and passes through seamless steel pipe inner bore, and two ends one end adopts to detour and is fastened on the power transmission shaft, and the other end directly is fixed on the hanging feet, the mill bar drives the emery wheel along continuous straight runs and rotates, the steel pipe inner wall defect is carried out grinding, and a reconditioning is unclean, and repeatedly reconditioning is until eliminating defective.
Yet there is following deficiency in existing grinding method:
(1) cutter is fixed on the knife bar, rotate along horizontal direction, and the forward and backward two ends of knife bar all are fixing, the axial line of knife bar and the parallel coincidence of seamless steel pipe center line, so can only carry out the whole machining of endoporus to seamless steel pipe, and inner wall defect is spot distribution mostly, and whole cutting reconditioning processing is during the consumption expenses of labour and caused waste to a certain extent;
(2) metal loss is big;
(3) dust pollution is heavy;
(4) noise is big, because hot rolling hollow forging wall unevenness, is to guarantee grinding quality, and the mill bar adopts the oar connection, so noise is bigger during grinding;
(5) cutter consumes high.

One cutter is fixedlyed connected with the front end of described drive link, and does and rotate in a circumferential direction.
Above-mentioned steel pipe inwall arrangement for grinding is at first located the position that needs reconditioning by the axial traveling and the rotating in a circumferential direction of steel pipe of walking dolly when work, driven by motor drive link rotation then, and then drive the cutter rotation, realize reconditioning to the steel pipe inwall.
Preferably, described drive link comprises:
One power transmission shaft that axially is provided with, described cutter is fixedlyed connected with the front end of power transmission shaft;
One sleeve pipe is placed in outside the described power transmission shaft, and described sleeve pipe is fixedlyed connected with connector, and the outer end of described sleeve pipe is provided with lead angle, and the endoporus correspondence position of described connector also is provided with lead angle, and described power transmission shaft is done in sleeve pipe and rotated in a circumferential direction.
The design of above-mentioned lead angle makes that drive link can be slight sag under its deadweight effect, thereby presses close to the steel pipe inwall, and its local defect is carried out reconditioning.
Preferably, described cutter is an emery wheel.
Preferably, be fixed with at least one sleeve between described power transmission shaft and the described emery wheel.
Preferably, be fixed with a connecting axle between described sleeve and the emery wheel.
The utility model makes it have following advantage compared to prior art by adopting technique scheme:
(1) simplifies the structure of device, made its installation, maintenance, easy to use easy to operate;
(2) original whole cutting is become local reconditioning, reduced the metal loss amount greatly;
