The full-automatic grinding equipment for the ball base surface of the conical bearing roller as claimed in claim 1, wherein the guide roller driving mechanism in the feeding mechanism comprises a guide roller driving motor connected to one end of a conveying guide roller and two transmission gears which are correspondingly arranged at the other ends of the two conveying guide rollers one by one and are meshed with each other; the two conveying guide rollers are obliquely arranged through inclination angle adjusting screws arranged on the feeding box support.
4. The full-automatic grinding equipment for the ball base surface of the conical bearing roller as claimed in claim 1 or 3, wherein the feeding mechanism further comprises a feeding box and a stopping mechanism; a feeding hole is formed in one side face of the feeding box, a feeding gate is installed on the feeding hole, and the feeding box is connected to the feeding hole of the feeding box; the stopping mechanism comprises a stopping cylinder arranged at the discharge end of the flexible feeding pipe and a stopping block connected to a piston rod of the stopping cylinder and capable of being inserted into a jack radially formed in the discharge end of the flexible feeding pipe.
5. The full-automatic grinding equipment for the ball base surface of the conical bearing roller as claimed in claim 1, wherein a guide hole is further formed in a cylinder support of the turntable locking mechanism, so that a piston rod of the locking cylinder drives the locking block to enter and exit the limiting groove in the turntable along the guide hole.
6. The full-automatic grinding device for the spherical basal plane of the conical bearing roller as claimed in claim 1, wherein the headstock feeding mechanism and the grinding head feeding mechanism each comprise a feed driving motor, a ball screw connected to a rotating shaft of the feed driving motor, and a slide plate mounted on the screw.
