Embodiment 1

[0045] Step 1: First, perform laser surface micro-texture processing, and then use a polishing machine to polish the surface of the guide rail substrate to ensure that the slag and flash on the surface of the substrate are completely removed. Use YLP-HP-1-100-100-100 fiber laser to process laser surface microtexture on the surface of the friction pair. The laser wavelength is 1064nm, the pulse width is 50-500ns, the laser power is 20-150W, and the laser pulse is repeated. The frequency is 10-100kHz, the duration of the laser to texture a single micro-pit 5 is 0.1-0.5ms or the diode-pumped solid-state light source (DPSS) YAG laser is used for laser surface micro-texture processing, and the focal length of the focusing lens is 50-100mm , the repetition frequency is 6.5-9.5khz, the laser wavelength is 532nm or 1064nm, the current intensity is 12-22A, the scanning speed is 4-16mm / s, and the auxiliary gas uses 99.9% N 2 , the pressure is 0.1-0.4Mpa. The micro-pit 5 is processed wi...

Abstract

The invention provides a guiding sliding friction pair of a multi-element composite texture, a processing method and application of the guiding sliding friction pair. Composite micro-texture morphology with orderly and uniformly distributed miniature pits and miniature protrusions is processed on a working plane of the friction pair through a laser device, and the miniature pits are filled with composite nanometer solid lubricants through a filling-pressing process. The laser micro-texture method is adopted to carry out non-contact processing and nanometer composite material filling and coating on a working plane of a guide rail, the creeping phenomenon of the machine tool guide rail can be effectively suppressed, the guide rail can be effectively lubricated under complex working conditions of a low speed, heavy load and the like, and the effects of reducing friction and resisting bonding are achieved.

Description

technical field [0001] The invention belongs to the technical field of friction pair self-lubrication, and in particular relates to a multi-component composite texture-guided sliding friction pair, a processing method and an application thereof. Background technique [0002] Today's world economic competition is becoming increasingly fierce, science and technology are advancing by leaps and bounds, machine tool products are being updated faster, more and more parts are becoming more and more complicated in structure and shape, and their precision requirements are getting higher and higher. The machine tool guide rail is a key component of the machine tool, and the processing workload of the guide rail accounts for about 40% of the entire machine tool processing workload. The guide rail is in a state of friction during operation. If there are no good lubrication measures, it will easily cause the wear of the guide rail. Due to the large working area of ​​the guide rail, the ...
