Inner polishing device for minor-caliber steel tube

Abstract

The invention discloses an inner polishing device for a minor-caliber steel tube. The inner polishing device for the minor-caliber steel tube comprises a steel tube fixing frame. A clamping rotary mechanism is arranged at one end of the steel tube fixing frame and provided with a grinding rod. A grinding head is arranged at the end of the grinding rod. Idler wheels are fixedly arranged at the lower end of the steel tube fixing frame. A workbench is fixedly installed at the upper end of the steel tube fixing frame. An arc-shaped steel tube locating groove is transversely formed in the workbench. The steel tube is placed in the steel tube locating groove. Supporting frames are integrally arranged at the left end and the right end of the workbench. An air cylinder frame is integrally arranged at the upper ends of the two supporting frames. At least two steel tube locating air cylinders are fixedly arranged on the air cylinder frame. A left protruding block and a right protruding block are integrally arranged on the workbench. A left steel tube pushing air cylinder is arranged at the left end of the left protruding block. A right steel tube pushing air cylinder is arranged at the right end of the right protruding block. By the adoption of the technical scheme, the steel tube is reliably fixed and can not shake in the machining process, machining quality can be guaranteed easily, and working efficiency is high.

Description

technical field [0001] The invention relates to the technical field of workpiece surface treatment devices, in particular to an internal polishing device for small-diameter steel pipes. Background technique [0002] As customers have higher and higher requirements on the surface quality of steel pipes, as an intermediate manufacturer, it is also necessary to continuously improve the surface quality of steel pipes. Especially in recent years, with the promotion and popularization of pneumatic and hydraulic equipment, the steel pipes originally produced by cold rolling process in the industry can no longer meet the needs of customers. Under the demand of the market situation, most of the polishing process of the inner wall of the steel pipe is to install a polishing wheel on the output shaft of the motor. The labor intensity is relatively large, the work efficiency is low, the product quality is not high, and the safety and reliability are low. So on July 5, 2012, Huzhou Hua...

Problems solved by technology

Especially in recent years, with the promotion and popularization of pneumatic and hydraulic equipment, the steel pipes originally produced by cold rolling process in the industry can no longer meet the needs of customers

Under the demand of the market situation, most of the polishing process of the inner wall of the steel pipe is to install a polishing wheel on the output shaft of the motor. The labor intensity is high, the work efficiency is low, the product quality is not high, and the safety and reliability are low.

So on July 5, 2012, Huzhou Huading Stainless Steel Pipe Industry Co., Ltd. invented the patent name "Small Diameter Steel Pipe Internal Polishing Device", China Authorized Announcement No. CN 202622538 U. Although the patented technical solution can reduce labor intensity, its structural setting Unreasonable, the steel pipe is positioned through the fixing hole on the support rod in the middle of the feeding platform, the steel pipe is easy to shake, and the steel pipe feeding mechanism clamps the steel pipe in a "cantilever beam" clamping, the steel pipe is easy to shake during processing, and it is difficult to guarantee the processing quality, low processing efficiency
