A method for forming inner surface micro-weave

Abstract

The invention discloses an inner surface micro-texture forming method. The inner surface micro-texture forming method is used for machining a micro-texture on the inner cavity wall of a workpiece. The method includes the following steps that firstly, the workpiece is installed on a worktable device; secondly, a positioning device pushes a driving device and a machining device to move to a moving position, and abrasive particles, protruding out of the surface of the machining device, of the machining device are attached to the inner cavity wall of the workpiece; thirdly, the driving device is operated to rotate so as to drive the machining device to rotate, and the abrasive particles can grind the inner cavity wall of the workpiece; and fourthly, the second step and the third step are executed cyclically till the workpiece is machined. The abrasive particles are arranged on the outer surface of the machining device and machine the inner cavity wall of the workpiece along with rotation of the machining device so as to form the micro-texture, and the machining efficiency is high; when the abrasive particles machine the workpiece, the abrasive particles rotate on a machining disc, abrasion of the abrasive particles is even, and the service life is long; and the positioning device drives the machining device to move to the moving position, so that the machining device is in a preset machining position of the workpiece, and the positioning precision is high.

Description

technical field [0001] The invention relates to the technical field of precision machining, in particular to a method for forming inner surface micro-weaving. 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...

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.
