The output end of the first push rod 55 is fixedly connected with the first shaft sleeve 4 through a connecting rod 56. Therefore, the first screw rod 52 can rotate by rotating the first hand wheel 53, and the base 51 can move on the guide rail 5, so that the initial positions of the first shaft sleeve 4 and the second shaft sleeve 42 can be adjusted simultaneously to match spherical blanks with different diameters.
Furthermore, as the second guide rod 31 needs to be capable of rotating, so as to change the polishing position of the polishing head 24, the output end of the second push rod 57 is fixedly connected with a connecting plate 58, meanwhile, the second sleeve 42 is fixedly connected with a shift lever 422 and an arc plate 421 concentric with the spindle 3, the connecting plate 58 is fixedly connected with a guide rod 582 and a driving plate 581 matched with the shift lever 422, the cross section of the driving plate 581 is in an arc shape, a driving groove 5811 is formed in the driving plate 581, the driving groove 5811 comprises a rotating groove section 58111 and a linear groove section 58112 arranged on one side of the rotating groove section 58111 far away from the connecting plate 58, the linear groove section 58112 is communicated with the rotating groove section 58111, and when the shift lever 422 moves in the rotating groove section 58111, the driving plate 581 can drive the shift lever 422 to rotate.

At this time, the second push rod 57 is started, the second push stopper 583 is pushed to move until the second push rod abuts against the adjusting block 586, at this time, the polishing head 24 on the second slide block 32 is already in contact with the spherical blank and is polished to a predetermined depth, when the second push rod 57 is further pushed, the spring 584 is compressed, the driving plate 581 drives the shift lever 422 to rotate, so that the second guide rod 31 rotates, the relative angle between the polishing head 24 on the second slide block 32 and the spherical blank is changed, and most of the surface of the spherical blank is polished. Then, the second push rod 57 can be retracted, the polishing head 24 on the second slider 32 can rotate to the original position, the motor 263 is stopped, the polishing head 24 on the second slider 32 can clamp the spherical rough blank, the motor 263 is started, the first push rod 55 is started, the polishing head 24 on the first slider 21 can polish the rest of the spherical rough blank, in the process, the driving plate 581 can drive the shift lever 422 to rotate, the polishing head 24 on the first slider 21 can polish all the surfaces of the spherical rough blank which are not polished, polishing of all the surfaces of the spherical rough blank is further achieved, manual disassembly and assembly of workers are not needed in the process to change the position of the spherical rough blank, and the processing efficiency is high.
