lock grinder

Abstract

The invention provides a lock polisher, belongs to the technical field of machinery, and solves the technical problems that when an existing lock automatic polisher polishes the two ends faces of a lock, the lock needs to be turned manually, and production efficiency is low. The lock polisher comprises a frame and a case fixed on the frame. A rotatable upper conveying wheel and a rotatable lower conveying wheel are disposed in the case. The rotatable upper conveying wheel and the rotatable lower conveying wheel are close and do not contact with each other. A polishing wheel and an auxiliary wheel are further disposed in the case. The polishing wheel is connected with a power mechanism which can drive the polishing wheel to rotate. A polishing abrasive belt sleeves the polishing wheel and the auxiliary wheel. The polishing wheel and the upper conveying wheel are close and do not contact with each other. The distance from the center of the upper conveying wheel to the center of the polishing wheel is equal to the distance from the center of the lower conveying wheel to the center of the polishing wheel. A plurality of upper concave openings for placing locks are evenly formed in the circumferential surface of the upper conveying wheel. A plurality of lower concave openings for placing locks are evenly formed in the circumferential surface of the lower conveying wheel. The lock polisher is high in polishing efficiency.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a grinder, in particular to a lock grinder. Background technique [0002] At present, the lock body is generally processed through the following processes: raw material cutting - die stamping - trimming and trimming - sanding - polishing - electroplating sealing - assembly - inspection - packaging, in which the grinding of the lock body is the two ends of the lock body Grinding, by grinding the two ends of the lock body, the size of the lock body can be qualified, and the end faces are smooth. [0003] After searching, for example, Chinese patent literature discloses an automatic lock body polishing machine [patent number: ZL 200910019362.4; authorized announcement number: CN 101758437A]. This lock body automatic polishing machine includes a fuselage frame part, a polishing belt rotating part, a lock body clamping part, a polishing movement part and an electrical control part, a...
