Description
Technical field
The present invention relates to a kind of steel ball grinding devices, are exactly a kind of novel steel ball fine grinding devices.
Background technology
In the prior art, steel ball mill is externally provided with charging tray in upper millstone, and upper millstone is equipped with adjacent feed inlet, discharge port,
Partition board is equipped between feed inlet and discharge port；Steel ball in charging tray enters mill by feed inlet and is ground, rotation grinding one
Come back in charging tray from mill by discharge port after week, the steel ball of discharge outlet is sprung up to feed inlet in charging tray, repeatedly into
Row grinding.
Problem of the existing technology is, for a batch steel ball into process of lapping, the uniformity is poor, in steel ball cyclic process,
Dead angle ball easy to produce, the low precision of steel ball grinding；In addition, steel ball feed inlet is also easy to produce jump-ball now due to the stacking of steel ball and rolling
As keeping the pressure between upper millstone and lower millstone unstable, uneven, the precision of steel ball grinding being caused to be affected.
Invention content
The technical problem to be solved in the present invention is to provide a kind of novel steel ball fine grinding devices, can reduce dead angle ball, jump-ball now
As that can improve the precision of steel ball grinding, improve grinding efficiency.
In order to solve the above technical problems, the present invention uses following technological means：
A kind of novel steel ball fine grinding device, including upper millstone, lower millstone, upper millstone are equipped with disk with lower millstone corresponding position
Ditch, upper millstone are equipped with discharge port, feed inlet, and partition board is equipped between discharge port and feed inlet；The discharge outlet is equipped with discharging
Guide groove, inlet chute is equipped at feed inlet, and inlet chute is equipped with guiding groove corresponding with the Pan Gou of lower millstone, the end of guiding groove
The Pan Gou of lower millstone is connected to by connector.
By the way that inlet chute, discharging guide groove is respectively set in discharge port, feed inlet, inlet chute is provided with the technical program
Guiding groove, guiding groove are corresponding to the Pan Gou of lower millstone so that steel ball to be ground enters lower mill by connector one by one along guiding groove
The Pan Gou of disk, first, having one caused by it is possible to prevente effectively from there is a large amount of steel balls to be ground to stack charging at feeding mouth originally
Point dead angle position of the steel ball to be ground in feed inlet cannot be introduced into feed inlet and become dead angle ball；Second is that can be to avoid to be ground
Goal jumping phenomena at feed inlet, avoids jumping due to scoring caused by steel ball stacking is fed into mutual rolling, extruding
Pressure caused by dynamic between upper millstone and lower millstone is unstable, uneven, so as to improve the precision of steel ball grinding, also
The velocity of rotation that lower millstone can be improved improves the efficiency of grinding.
Further optimal technical scheme is as follows：
The top of the inlet chute is equipped with postive stop baffle, and postive stop baffle is arranged in parallel with inlet chute, process of lapping
In, the interval fed between baffle and inlet chute only allows steel ball to be ground individually to pass sequentially through.
By the way that postive stop baffle is arranged, steel ball to be ground can be further increased under guiding groove is entered by connector one by one
The accuracy of the Pan Gou of mill.
The postive stop baffle is arranged before connector.Above-mentioned setting has ensured steel ball to be ground at the place of postive stop baffle
Enter the Pan Gou of lower millstone by connector one by one along guiding groove

Plate tilts, and arc exports diameter of the interval between the bottom end and the disk ditch of lower millstone of plate less than the steel ball of grinding.
Plate is exported by the way that arc is arranged, the steel steel ball of discharge outlet rolls under the drive of the rotation of lower millstone from discharge port
It moves out, under the promotion of the inertia and rear adjacent steel ball of steel ball rotation, arcuately exports plate and export outward.
The discharge outlet is equipped with spray gun, and spray gun is connected and fixed with upper millstone, and the hydrojet direction of spray gun arcuately exports
Plate is arranged.
By the way that spray gun is arranged, steel ball can be washed away outward using high pressure liquid spray, so that steel ball is exported, the bottom of discharge port is equipped with
Sieve and liquid outlet hydrojet return to collecting tank by liquid outlet, can recycle.
The end of the described discharging guide groove connects discharging bin, and the feed end of inlet chute connects feed hopper, discharging bin with point
Choosing sieve connection, separating sieve are equipped with waste outlet, qualified steel ball outlet, steel ball to be ground outlet.
Original equipment, as soon as batch steel ball is stacked in charging tray, by feed inlet enter upper millstone and lower millstone to
Pan Gou；Grinding is come back to by discharge port in charging tray after a week, and above process is repeated, and grinding efficiency is low, yield rate is low.
By the way that separating sieve is arranged, the steel ball after grinding can be sorted using separating sieve, sub-electing defect ware can be with
Further avoid defect ware in process of lapping to neighbouring steel ball rolling during formed abrasion, so as to improve grinding
Yield rate；It after qualified steel ball sub-elects, is no longer ground in vain, first, grinding cost can be saved, second is that can be to avoid conjunction
The steel ball of lattice in invalid process of lapping, caused by the jump-ball phenomenon at substandard products steel ball or feed inlet surface damage at
For substandard products ball, to improve yield rate.Separating sieve is specifically configured to the prior art, and details are not described herein.
Steel ball the to be ground outlet of the separating sieve is connect by conveying device with feed hopper.
By above-mentioned setting, an automatic grinding, sorting, the production line ground again can be become, further increase production
Efficiency.
