Abstract
The utility model relates to a mirror surface bearing electrolytic grinding processing equipment, which is designed to solve the problem that the superfine processing of the prior axle bearing work rollaway nest is difficult. The equipment has an electrolysis grinding head which is formed of a negative pole body and two oilstones. The electrolysis grinding head is arranged on the surface of the rotary bearing work rollaway nest, the power source is connected with the electrolyte, the convex part of the surface of the rollaway nest produces anode solution under the effect of the electric field and the electrolyte, and anode solution is grinded away by the oilstones. The electrolysis and the grinding are carried on in turn, the electrolysis product is carried off by the mobile electrolyte after the grinding, and until the qualified mirror surface bearing is processed. The utility model can be used for the superfine processing of bearings, in particular the superfine processing of the large-scale bearings.
Description
The utility model belongs to the minute surface bearing electrolytic grinding process equipment that the superfinish bearing race is used.
The mirror finishing of rolling bearing is that bearing race is carried out superfinish, makes it obtain higher surface roughness precision, thus the working life of improving bearing greatly.In order to improve the surface roughness quality of large-size bearing roller way, at present domesticly all bearing is carried out fine finishing, and surface roughness can only reach with hand-polished method
Precision, the regulation that is difficult to make the surface roughness of the work raceway of bearing to be up to state standards.
The purpose of this utility model provides a kind of minute surface bearing electrolytic grinding process equipment, uses this equipment can improve bearing working raceway face roughness precision and working life greatly.
The utility model is realized by following measure.Mainly moving (walking) mechanism, main drive gear, race ring chucks and electrolysis power device by lathe bed, electrolysis bistrique, bistrique bearing, bistrique forms.It is characterized in that: the main shaft that the race ring chuck is installed is connected with motor by gear; Bistrique is made up of cathode and two blocks of oilstones, and cathode is positioned at the centre of bistrique, and oilstone is positioned at the both sides up and down of cathode; The outer profile curve of cathode and oilstone is identical with the curve of processed race ring work raceway; The position that oilstone is installed at bistrique is provided with the oilstone position regulator; When two blocks of oilstones on the bistrique contacted with the work raceway face of race ring, should guarantee to have between the work raceway face of cathode and race ring can be by the gap of electrolytic solution; The bistrique bearing that the electrolysis bistrique is installed is fixed on the shifter, is connected for unsteady between electrolysis bistrique and the bistrique bearing; The cathode of bistrique is connected with the negative electrode of electrolysis power device, and race ring is connected by the anode of chuck with the electrolysis power device; Being processed with near a side of workpiece processing face on the cathode can be to the hole of surface to be machined jet electrolytic liquid, and this hole is connected with cell liquor pump.The cathode on the electrolysis bistrique and the gap of surface to be machined are 0.1～1.5mm.The anode of power supply unit is connected with race ring with chuck by brush.It is in order to overcome the error that race ring is installed that bistrique and bistrique bearing unsteady is connected, and what guarantee all the time that bistrique contacts with race ring work raceway coincide.The cathode of electrolysis bistrique also can be arranged with the oilstone branch, and cathode directly is connected with the bistrique bearing, and be fixed on the bistrique shifter by cathode block.By adjusting the bistrique shifter, determine the gap between cathode and the workpiece.Oilstone is installed on the oilstone regulating device, contacts with the race ring surface to be machined, is connected with lathe bed by support.
During equipment work, race ring is installed on the chuck, adjusts bistrique frame shifter, make the oilstone on the bistrique and the work raceway of cathode alignment bearings circle, and pressure a little.Split type electrolysis bistrique should be adjusted the gap of cathode and workpiece, adjusts the pressure of oilstone and working surface.Starting device makes the race ring rotation, and cell liquor pump is full of electrolytic solution between cathode and the workpiece.Under the effect of electric field and electrolytic solution, produce anodic solution as the projection of the race ring work raceway face of anode, form anode film, the oilstone that is in contact with it subsequently is worn, exposes new metal surface, proceeds electrolysis.Electrolysis and ablation hocket like this, and electrolysate is taken away by the electrolytic solution that flows, and processing are proceeded, until reaching processing request.Can significantly improve the precision of bearing race surface roughness, can reach
More than.
The utility model has the advantages that owing to adopt electrolysis and ablation operative workpiece simultaneously, the roughness precision on bearing race surface is improved greatly, also obviously prolong its working life.The bearing surface roughness by
Bring up to
, can make the life-span of bearing improve more than 6 times.Can be widely used in various bearings, particularly the processing on large-size bearing roller way surface.
