Cambered surface burnishing device for machining inner wall of crane hydraulic oil cylinder body

Abstract

The invention relates to the technical field of burnishing devices, in particular to a cambered surface burnishing device for machining the inner wall of a crane hydraulic oil cylinder body. The burnishing device comprises a burnishing frame. A side plate is arranged at the top of the burnishing frame, an electric push rod is arranged at the top of the side plate, a movable plate is arranged on apiston rod of the electric push rod, a rotating rod is rotationally arranged on the surface of the movable plate, a dust collecting box is rotationally arranged at the top of the rotating rod, the bottom of the rotating rod communicates with a burnishing roll, a plurality of burnishing plates are arranged on the outer wall of the burnishing roll, a plurality of through holes are formed in the outer wall of the burnishing roll and communicate with the interior of the dust collecting box, a fixed slot is formed in the top of the burnishing frame, both sides of the fixed slot are in threaded connection with fixing devices, the fixing devices are located right under the burnishing roll, a cambered plate is rotationally arranged at the end part of a corresponding screw, and a folding stool is rotationally arranged in a folding groove in the outer wall of the burnishing frame. According to the burnishing device, dust can be conveniently collected, hydraulic oil cylinder bodies of different sizes can be fixed, and workers can have a rest on the burnishing device.

Description

technical field [0001] The invention relates to the technical field of polishing devices, in particular to an arc surface polishing device for processing the inner wall of a hydraulic oil cylinder of a crane. Background technique [0002] The hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swinging motion); it has a simple structure and reliable operation; when it is used to realize reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap , the movement is stable, so it is widely used in cranes. In the production of hydraulic cylinders, the inner wall of the cylinder needs to be processed and polished. Polishing refers to the use of mechanical, chemical or electrochemical effects to reduce the surface roughness of the workpiece to obtain a bright finish. , The processing method of flat surface; [0003] However, the current polishing device ...
