Polishing device for inner surface of straight pipe

Abstract

The invention belongs to the technical field of polishing of the inner surfaces of straight pipes and particularly relates to a polishing device for the inner surface of a straight pipe. The polishingdevice comprises an overall machine tool frame and a three-jaw chuck arranged on the overall machine tool frame; and the overall machine tool frame comprises a tool body and further comprises a spindle box, a lead screw and a tailstock which are arranged on the tool body. The polishing device is characterized in that a clamping machining part, a guiding part and a magnetic pole part are arrangedon the overall machine tool frame. The polishing device is compact in structure, high in universality, easy to operate and convenient to mount; a magnetic pole chain is mounted, grinding particles arefully utilized to polish the straight pipe which is long and small in inner diameter, and the effect is better especially for a magnetic conductive straight pipe; and compared with a traditional modeof additionally arranging an auxiliary magnetic pole, according to the polishing device, leftward-rightward moving of the magnetic pole chain can be controlled, and the inner surface of a workpiece can be polished thoroughly.

Description

technical field [0001] The invention belongs to the technical field of straight pipe inner surface polishing, and in particular relates to a straight pipe inner surface polishing device. Background technique [0002] With the rapid development of high-end high-tech industries such as aerospace, medical treatment, and petroleum, various new types of parts have emerged as the times require. The technical requirements for parts are also getting higher and higher. Not only must the dimensional accuracy of the parts be guaranteed, but also the parts are required to have better microscopic surface morphology, corrosion resistance and fatigue resistance. The requirements for the inner surface of straight pipe parts Also getting higher and higher. Pipe workpieces are widely used in daily production, and these workpieces will produce stains, rust, etc. during use, which will affect the use of such workpieces. The use of knocking and chemical polishing will cause damage to the workp...

AI Technical Summary

Problems solved by technology

In order to improve the efficiency of magnetic grinding, auxiliary polishing tools are usually added inside the pipe fittings to increase the magnetic induction intensity in a certain space, thereby increasing the grinding pressure of magnetic abrasive particles. The rigidity of the magnetic particle brush is improved and the trajectory of the magnetic abrasive particles is single during grinding. Deep scratches are easy to appear on the surface after processing, the surface quality is not easy to control, and the processing effect is not ideal.
