Abrasive flow polishing machining device for small-diameter elbow

Abstract

The invention provides an abrasive flow polishing machining device for a small-diameter elbow. The device is composed of two parts including a clamp clamping part and a transmission part, an I-shapedplate is installed on an abrasive cylinder through a bolt, a connecting bolt and a V-shaped limiting guide column are connected through a spherical protrusion, a threaded hole in the I-shaped plate ismatched with the connecting bolt, and the clamping degree of the V-shaped limiting guide column to the small-diameter elbow can be adjusted through rotating the connecting bolt. The transmission function of the transmission part is achieved through a V-belt wheel groove in the abrasive cylinder, a motor rotating shaft and the abrasive cylinder are connected through a V belt, synchronous rotationof the abrasive cylinder and the small-diameter elbow can be achieved through adjusting the rotating speed of the motor rotating shaft, grinding materials are introduced into a grinding material inlet, and polishing treatment of the inner wall and the outer wall of the small-diameter elbow is further achieved. The abrasive flow polishing machining device is convenient to install, easy and reliableto use and capable of polishing bent pipelines of different sizes.

Description

technical field [0001] The invention relates to the field of precision machining, in particular to a small-diameter elbow abrasive flow polishing device. Background technique [0002] The principle of abrasive flow polishing technology is that during abrasive flow processing, the fixture cooperates with the workpiece to form a processing channel, and two opposite abrasive cylinders make the abrasive squeeze back and forth in this channel. Abrasives grind the channel surface or corners uniformly and gradually, producing polishing and chamfering effects. Small-diameter elbows are widely used in aerospace, medical equipment, ship pipes, automobile oil pipes, bathrooms, air-conditioning refrigeration pipes, lighting, construction machinery and other industries. With the continuous improvement of equipment manufacturing industry's requirements for equipment precision and miniaturization, complex The quality requirements of the inner and outer surfaces of the pipeline are also co...

AI Technical Summary

Problems solved by technology

[0003] Traditional abrasive flow polishing fixtures can only polish the inner wall of straight pipes. In order to meet the polishing requirements of abrasive flow for small-diameter elbows, an abrasive flow polishing device for small-diameter elbows has been invented. The invention adopts four designs A V-shaped limit guide column clamps the small-diameter elbow, and uses a belt to connect the motor shaft and the abrasive barrel to realize the synchronous rotation of the small-diameter elbow and the abrasive barrel. surface polishing
