Laser helically rotating optical module applied to laser process equipment

Abstract

The invention relates to a laser helically rotating optical module applied to laser process equipment. The optical module is characterized in that a left backing plate, a middle backing plate and a right backing plate are parallel arranged on a base plate at intervals; the left backing plate is internally provided with a first bearing; the first bearing is provided with a first lens group inside; the middle backing plate is internally provided with a second bearing; the second bearing is provided with a second lens group inside; the right backing plate is internally provided with a third bearing and a fourth bearing which are mutually independent; the third bearing is provided with a third lens group inside; the fourth bearing is provided with a fourth lens group inside; the first bearing and the third bearing are connected by a spindle; the second bearing is arranged on the spindle; the spindle is in drive connection with a first motor by virtue of a first synchronous belt wheel; the second bearing is in drive connection with a ball screw; the ball screw is in drive connection with a second motor by virtue of a second synchronous belt wheel; and the fourth bearing is in drive connection with a third motor by virtue of a third synchronous belt wheel. The equipment is applied to laser hole drilling (cutting) equipment to regulate the drilling (cutting) taper and aperture size.

Description

technical field [0001] The invention relates to a laser spiral rotating optical module in laser processing (laser drilling, laser cutting, etc.) equipment, and belongs to the technical field of laser precision processing equipment. Background technique [0002] At present, traditional processing equipment can no longer satisfy the processing of products such as ceramic drilling, glass cutting, fuel injection nozzle drilling, and cardiovascular stent cutting; the drilling (cutting) of this type of product has been changed to laser processing, and some Special products have very high requirements on the roundness and edge of the processing hole (such as the processing of cardiovascular stents), and some special applications need to process the reverse taper hole or reverse taper edge (such as the oil nozzle needs to process the hole with the reverse taper); traditional The current laser drilling (cutting) method uses pulses for processing, or uses laser and motion platform int...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a laser spiral optical module suitable for laser processing equipment, which aims to effectively solve the problem of taper that is difficult to eliminate in traditional laser processing methods when processing deep holes, and the inability to process inverted taper holes , the problem that the ratio of diameter to depth is too small and the processing efficiency is low; the utility model can rotate the optical path during processing, and adjust the taper of the processing hole (cutting) at any time to realize deep hole processing, and can adjust the diameter of the processed hole auto-size
