A closed inflatable surface pressurized clamping device, system and processing method thereof

Abstract

The invention relates to the technical field of laser machining, in particular to a closed type air inflation face pressure boosting clamping device and system and a machining method thereof. The clamping device comprises a workpiece containing cavity composed of a flat base plate and a side wall arranged on the base plate in a surrounding manner; an air pipe connector is arranged on the side wall of the workpiece containing cavity and connected with an external air source, a light-transmittable plate is arranged at the top of the workpiece containing cavity, and therefore external lasers can penetrate the light-transmittable plate from the top of the workpiece containing cavity to income into a to-be-machined workpiece; and a confined space isolated from external atmosphere is defined by the light-transmittable plate and the workpiece containing cavity. The closed type air inflation face pressure boosting clamping device effectively solves the problem that a traditional absorption type clamp is insufficient in clamping performance; a face pressing type method is adopted for the device, and therefore the clamping degree and the flatness of the workpiece can be greatly improved; and meanwhile, the closed type air inflation pressure boosting manner is adopted for compression, inflation of air is needed only one time, air waste is avoided, and continuous work of any power system like a vacuum pump is not needed.

Description

technical field [0001] The invention relates to the technical field of laser processing, in particular to a closed inflatable surface pressurization and clamping device, a closed inflatable surface pressurization and clamping system and a processing method using the closed inflatable surface pressurization and clamping system. Background technique [0002] Laser processing is to use the energy of light to reach a high energy density at the focus point after being focused by the lens, and to process by the photothermal effect. Laser processing has the characteristics of fast processing speed, small surface deformation, and can process various materials. Laser beams can perform various processing on materials, such as drilling, cutting, scribing, welding, heat treatment, etc. Compared with traditional processing technology, laser processing technology has the advantages of less material waste, obvious cost effect in large-scale production, and strong adaptability to processin...

AI Technical Summary

Problems solved by technology

However, there are many defects in the use of adsorption clamping. For example, in the process of laser processing, the vacuum pump must continue to work to ensure a certain degree of vacuum, and the gas pumped out by the vacuum pump cannot be recycled, resulting in waste. The way of suction is not the way of uniform clamping of the surface, so the adsorption is not uniform, and the flatness of the clamping is relatively poor
