[ detailed description ] embodiments

Referring to the attached drawings 1 to 4 in the specification, the utility model relates to an automatic grinding device for workpiece, which is used for grinding workpiece 4 and comprises a frame 1, a screw bracket 26, a screw 10, a screw motor 5, a screw seat 21, a grinding wheel bracket 3, a grinding wheel 17, a sensor 15, a motor bracket 7, a motor 2 and other parts.

Wherein, a guide rail 11 is installed on the frame 1, and the guide rail 11 can be pushed by external force to move along the frame 1. The workpiece 4 is arranged on the guide rail 11 and is ground along with the linkage of the guide rail 11.

The screw bracket 26 is fixed on the frame 1. The lead screw 10 is pivotally connected to a lead screw bracket 26. The screw bracket 26 is vertically arranged, and a vertical guide groove 27 is arranged on the screw bracket.

The screw motor 5 is mounted on a screw bracket 26, which is connected to and drives the screw 10 to rotate. The screw base 21 is connected to the screw 10 and can move along the screw 10. The lead screw base 21 is matched with the vertical guide groove 27 in the opposite direction, so that the lead screw base 21 can be lifted along the vertical guide groove 27, and the lead screw base 21 is prevented from deflecting.

The grinding wheel carriage 3 is connected to a screw base 21. Specifically, the screw seat 21 is connected with a connecting plate 19; a universal joint 23 is installed to the one end of connecting plate 19, universal joint 23 and the wheel support 3 of polishing are connected, realize polishing wheel support 3 and polishing wheel 17 reciprocate, make polishing wheel 17 can be close to automatically and keep away from work piece 4, realize polishing of work piece 4.
