Polishing device for inner surface of oil cylinder

Abstract

The invention discloses a polishing device for the inner surface of an oil cylinder. The polishing device comprises a polishing machine base and a polishing machine beam. A guide rail is arranged at the bottom of the polishing machine beam. A nut seat is arranged on the guide rail. The nut seat is in sliding connection with the guide rail. A screw rod is sleeved with the nut seat. One end of the screw rod is fixedly connected with a rotating shaft of a speed reducer through a coupling. The speed reducer is connected with an output shaft of a first motor. The other end of the screw rod is rotationally connected with a first bearing seat. The first motor and the first bearing seat are both fixed in the polishing machine beam. A connecting plate is arranged at the bottom of the nut seat. Theconnecting plate is fixedly connected with the nut seat. First cylinders are fixedly arranged at the bottom of the connecting plate. According to the polishing device for the inner surface of the oilcylinder, by arranging the first motor, the first cylinders, second cylinders and magnetic abrasives, the problems of a complicated polishing device and uneven polishing generated during polishing ofthe inner surface of the oil cylinder are solved.

Description

Technical field [0001] The invention relates to the technical field of polishing equipment, in particular to a polishing device for the inner surface of an oil cylinder. Background technique [0002] The oil cylinder generally refers to the hydraulic cylinder. The hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion. It has a simple structure and reliable work. When it is used to achieve reciprocating motion, it can eliminate the deceleration device and has no transmission. Clearance, smooth movement, so it is widely used in various mechanical hydraulic systems. The oil cylinder requires a high degree of roughness on its inner surface. On the one hand, the inner surface is smooth to ensure uniform internal pressure, and on the other hand, to avoid surface defects. The resulting pollution and corrosion increase the service life. Traditional polishing tools are difficult to process the inner surfac...
