Embodiment Construction

[0014] combine figure 1 The rotary laser head auxiliary gas transmission device of the laser processing machine tool includes a cantilever beam 10, a sealed air cavity sleeve 18, an upper bearing gland 12, a lower bearing gland 19, a rotating shaft 11, a sealed bearing A15, a sealed bearing B16, Stepper motor 9, synchronous pulley A7, synchronous pulley B8, light-transmitting glass 2, high-transmittance lens 5, lens gland 4, chassis shell 3, laser head 22, focusing lens sleeve 27, 45° total reflection The mirror 24 and the laser head emit the light vent 25. The cantilever beam 10 is a rectangular cavity formed by six hard aluminum alloy plates, the height of the cantilever beam 10 is 6-7cm, and the ratio of width to length is 1:5-1:6. The cantilever beam 10 is horizontally installed on the Z-axis vertical workbench 6 through bolt connection. A through hole is opened at the right end of the cantilever beam 10, and a sealed air cavity sleeve 18 is fixed on the lower end surface...

Abstract

The invention relates to an application occasion that requires combination of the axial rotation of a laser head and the lifting motion in a vertical direction in the field of laser surface fine processing, in particular to a rotary laser head auxiliary gas transmission device for a laser processing machine tool. By the device, the rotation and up-and-down linear motion of the laser head can be realized and an independent gas cavity is adopted to transmit an auxiliary gas, so good gas tightness of the system and output pressure intensity of the auxiliary gas can be guaranteed; due to a focusing lens in the laser head, axial adjustment can be realized so as to change the position of a focusing point of a laser beam; and during rotation, the laser head keeps rotation coaxiality with higher precision.

Description

technical field [0001] The invention relates to the application occasions in the field of laser surface micromachining that require the combination of the axial rotation of the laser head and the vertical lifting movement, in particular to a rotating laser head auxiliary gas transmission device of a laser processing machine tool. Background technique [0002] Laser surface micromachining technology is highly valued in the surface microtopography processing method of friction pair due to its advantages of fast processing speed, no pollution to the environment and excellent dimensional control ability. A new laser micro-modeling process is proposed in the "single pulse same point interval multiple times method" with patent application number CN200610039758.1. In this patent, a control scheme is adopted in which the workpiece is clamped and rotated, and the laser head is moved up and down linearly. If processing large machine components, it is difficult to couple the workpiece...
