Description

Technical Field

[0001] The utility model belongs to the field of polishing devices, and in particular relates to a polishing device for processing oil production pipes. Background Art

[0002] Polishing refers to a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of a workpiece to obtain a bright and smooth surface. It is a modification process of the workpiece surface using polishing tools and abrasive particles or other polishing media; high-pressure oil pipes are usually made of stainless steel and are commonly used in the transportation of hydraulic oil pipes for engineering machinery, submarine natural gas, petroleum, irrigation, steel mills, chemical plants and other media.

[0003] The Chinese patent with the publication number CN218017823U discloses a high-pressure oil pipe inner wall polishing device, wherein the side wall of the power supply box is symmetrically welded with an electric telescopic rod; the end of the electric telescopic rod is welded with a tram; the end surface of the power supply box is horizontally welded with a rotating motor; the transmission end of the rotating motor is butt-jointed with a rotating shaft; a rotating seat is welded with the side wall of the rotating shaft; an extrusion plug rod is installed in the interior of the rotating seat; an extrusion spring is vertically installed at the lower end of the extrusion plug rod; a push rod is vertically welded with the upper end surface of the extrusion plug rod; the push rod passes through the upper end surface of the rotating seat; a clamping seat is welded with the end of the push rod; The internal clamping device of the clamping seat is installed with a polishing oil stone; the end of the rotating shaft is butt-connected with a shooting probe; the end face of the power supply box is welded with a control box; a wire is installed outside the control box; the utility model can provide a high-pressure oil pipe inner wall polishing device that adopts a mechanized grinding method to be fast and convenient and a visual grinding method to facilitate observation and inspection. However, the high-pressure oil pipe inner wall polishing device in this application uses a single fixed-position extrusion spring to cooperate with the polishing oil stone, and has low stability during polishing. When the oil pipe is placed, the spring needs to be manually compressed to make the polishing oil stone squeeze and contact with the inner wall of the oil pipe, which is inconvenient to operate.

[0004] In view of this, the present utility model is proposed. Utility Model Content
