1. according to the invention, the grinding box, the grinding materials, the lifting mechanism and the moving mechanism are arranged, so that when the screw is ground, the screw is fixed through the small chuck, the connecting rod is driven to rotate through the starting servo motor, the connecting rod drives the screw rod to rotate through the first bevel gear and the second bevel gear, the moving block moves up and down through the principle of screw thread transmission, the moving block can drive the moving plate to move up and down, the moving plate can drive the screw rod to move up and down, the driving motor can drive the screw rod to rotate, the screw rod can be driven by the moving plate to be inserted into the grinding materials, the screw rod can rotate in the grinding materials, the outer wall of the screw rod and the grinding materials are mutually rubbed, burrs are removed through grinding materials, and therefore, after the screw rod enters the inside of the grinding materials, the outer wall of the screw rod and the inside of teeth are completely covered by the grinding materials, the situation that the screw rod cannot be ground uniformly due to consumption of the grinding wheel disc is avoided, and the situation that the inside of the teeth cannot be ground is avoided, so that grinding and accuracy is improved.
2. Through setting up moving mechanism, the dead lever, remove seat, the supporting disk, the connecting axle, small-size chuck, thereby make when fixing the screw rod, can fix the other end of screw rod through the small-size chuck of supporting disk top, thereby make the screw rod can rotate between removing seat and movable plate, and supporting disk and small-size chuck can support and spacing the other end of screw rod, avoid the other end of screw rod not fixed, when causing the screw rod to rotate, the screw rod appears getting rid of the circumstances that flies, and through setting up the dead lever, the dead lever can play and connect fixed effect to removing between seat and the movable plate, the dead lever can not prevent the abrasive material to cover the grinding to the screw rod again.
3. Through setting up the toper seat to make when carrying out the work of polishing, when the dead lever inserts the inside to the abrasive material, the one end tip portion of toper seat can make the dead lever and remove the plug of seat more smooth and easy.
4. Through setting up cross baffle, grinding district, spliced pole, control bearing frame to make the staff can select different abrasive materials to polish according to the demand of polishing of screw rod, and through the cooperation of spliced pole and control bearing frame, when making the change abrasive material, it is more convenient to change, only needs to rotate the grinding case just can accomplish the change of abrasive material.
