A kind of inner surface micro-woven forming equipment

Abstract

The invention discloses internal surface microtexture forming equipment used for machining microtextures on the inner cavity walls of workpieces. The internal surface microtexture forming equipment comprises a positioning device, a driving device arranged on the positioning device, and a machining device arranged on the driving device. The machining device is cylindrical, and the outer circumferential face of the machining device is provided with a plurality of abrasive particles at least partially protruding out of the surface of the machining device. The positioning device pushes the driving device to be moved to a moving position, so that the abrasive particles are attached to the inner cavity walls of the workpieces. The driving device drives the machining device to rotate, so that the abrasive particles grind the inner cavity walls of the workpieces. The abrasive particles are arranged on the outer surface of the machining device are used for machining the inner cavity walls of the workpieces along with rotation of the machining device so as to form the microtextures, and the machining efficiency is high. When machining the workpieces, the abrasive particles can rotate on a machining plate, abrasive wear is made even and the service life is long. The positioning device drives the machining device to be moved to the moving position, the machining device is located at preset machining positions of the workpieces, and thus positioning efficiency is high.

Description

technical field [0001] The invention relates to the technical field of precision machining, in particular to an inner surface micro-weaving forming equipment. Background technique [0002] Micro-textures are processed on the surface of some precision equipment with relative movement, and the micro-textures can store grease, lubricating fluid, etc. During the sliding process of the opposite surface, a lubricated sliding film is formed on the sliding surface, so that the precision equipment has good lubrication performance. Wherein, the micro-texture is nanoscale or micron-scale grooves or pits arranged on a flat surface. [0003] The micro-texture is processed on the surface of the parts without affecting the precise fit between the parts, and there is a micro-texture on the sliding surface of the parts, which makes the parts have a good lubricating effect, and reduces friction and heat generation of the parts. Reduce wear and prolong service life. [0004] Micro-texture i...

AI Technical Summary

Problems solved by technology

However, the existing methods of machining micro-textures on the inner surface of parts usually use photolithography, electrolytic machining, etc. These processing techniques are complex, costly, and the processing position is inconvenient to adjust, the processing accuracy is low, and the micro-texture effect of processing is poor.
