Referring to fig. 1 to 3, in embodiment 1 of the present invention, an automatic screening conical ball grinder includes a housing 2, a grinding bin 1, an infrared sensor 24, a conical grinding disc 6, a lower grinding disc 7, a main motor 4, an auxiliary motor 26, a steel ball collecting port 18, a grinding material collecting port 16, a screw conveyor 20, and a hydraulic cylinder 15; a V-shaped lower grinding disc 7 is fixedly connected inside the shell 2; the bottom of the lower grinding disc 7 is fixedly connected with a partition plate 14; a hydraulic cylinder 15 is fixedly connected to the middle of the partition plate 14, and a hydraulic rod 13 of the hydraulic cylinder 15 is fixedly connected to the shaft hole 9 in the conical grinding disc 6; a rotating shaft 5 is fixedly connected in the shaft hole 9, the top of the rotating shaft 5 is fixedly connected with a main motor 4, and the main motor 4 is fixedly connected to the top of the shell 2 through a fixing frame 3; a spherical track groove 8 is arranged between the conical grinding disc 6 and the lower grinding disc 7; the bottom of the track groove 8 is connected with the bottom of the screw conveyor 20 through the guide-out groove 12, and the discharge hole 25 at the top of the screw conveyor 20 is connected with the feeding channel 27.
When the ball grinder is used, the steel balls are fed into the feeding channel 27, the steel balls are ground in the track groove 8 between the conical grinding disc 6 and the lower grinding disc 7, and finally the ground steel balls pass through the bottom guide-out groove 12 to leave the ball grinder.
The top of the shell 2 is fixedly connected with a grinding material box 1, the side surface of the grinding material box 1 is fixedly connected with a grinding material pipe 28, and the grinding material pipe 28 points to the feeding channel 27. The bottom of the feeding channel 27 is connected with the feeding notch 23, the side wall of the feeding notch 23 is connected with the infrared inductor 24, and the bottom of the feeding notch 23 is communicated with the top end of the track groove 8. And the top of the hydraulic rod 13 is sleeved with a positioning ring 11, the positioning ring 11 is embedded in the shaft hole 9, and the flange 10 at the top of the hydraulic cylinder 15 is connected with the positioning ring 11 through a screw 29. The track groove 8 rotates for a plurality of times around the conical grinding disc 6 and finally points to the guide-out groove 12 at the bottom, and the diameter of the track groove 8 is reduced proportionally from top to bottom. The screw conveyor 20 comprises a secondary motor 26, a screw 22 and a cylinder 21, the secondary motor 26 being located at the top of the screw conveyor 20. The bottom of the spiral conveyor 20 is fixedly connected with a plurality of screening holes 19, and a steel ball collecting port 18 is connected below the screening holes 19.

The steel balls with unqualified sizes cannot pass through the screening holes 19, the steel balls can be conveyed to the top by the started screw conveyor 20, the steel balls pass through the discharge hole 25 and enter the feeding notch 23 again, matched abrasive materials pass through the abrasive material screen 17 and leave, the infrared inductor 24 transmits information when the steel balls pass through the feeding notch 23, the matched abrasive materials are redistributed to the abrasive material box 1, and repeated grinding is carried out again until the sizes of all the steel balls meet the standard. The steel balls with unqualified sizes can be repeatedly transported to the feeding notch 23 to repeat the polishing process.
The working principle of the invention is as follows:
the ball grinder is used for putting grinding materials between an upper grinding disc 7 and a lower grinding disc 7 and then rotating relatively to enable the steel ball to be ground under pressure while being in the Guidong. The device pressurizes the conical grinding disc 6 through the hydraulic cylinder 15, and pressurizes and polishes the steel balls in the track grooves 8 while driving the steel balls to rotate. Because the whole track groove 8 is always a through unique path, the lengths of the friction paths of all the track grooves 8 entering the grinding machine in one grinding cycle are completely consistent, and the problem that the grinding efficiency is different due to different grinding distances of steel balls on the track grooves 8 with different inner and outer diameters is solved. Screening holes 19 with the size of the standard steel balls are formed in the bottom of the screw conveyor 20, qualified steel balls are screened in the dog, unqualified steel balls do not need an additional groove, the walking groove is conveyed to a discharge hole 25 in the top through the screw conveyor 20, and the steel balls enter the ball grinding machine again and are ground again. Because this ball grinder screening and pay-off process do not need manual processing for full automatic operation, all steel balls that drop into can all polish to suitable size and just can stop work quietly, do not need the manual inspection and the manual operation of in-process, great manpower and materials have been saved, simultaneously because only 8 track grooves of polishing, do not have the big problem of interior and exterior polishing drop-down difference, very big improvement the efficiency of ball grinder.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
