A steel pipe inner polishing positioning device

Abstract

The invention discloses a steel tube internal polishing locating device which comprises a steel tube fixing frame and illuminating lamps. A worktable is fixedly mounted at the upper end of the steel tube fixing frame, an arc steel tube fixing groove is transversely formed in the in the worktable, a steel tube is arranged in the steel tube locating groove, supporting frames are integrally arranged at the left end and the right end of the worktable, air cylinder frames are 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 frames, the head of a piston rod of each steel tube locating air cylinder is connected with a press block in a sleeved mode, arc grooves are formed in the lower end faces of the press blocks, a left lug and a right lug are integrally arranged on the worktable, a left steel tube pushing air cylinder is arranged at the left end of the left lug, the head of a piston rod of the left steel tube pushing air cylinder is fixedly connected with the left lug, a right steel tube pushing air cylinder is arranged at the right end of the right lug, and the head of a piston rod of the right steel tube pushing air cylinder is fixedly connected with the right lug. According to the technical scheme, the steel tube is reliably fixed, shake is avoided in the machining process, the machining quality is easy to ensure, and the working efficiency is high.

Description

technical field [0001] The invention relates to the technical field of workpiece surface treatment devices, in particular to a steel pipe inner polishing positioning device. 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 Huading Stainle...

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
