Problems solved by technology

When it is loosened, springback deformation will occur, destroying the roundness of the pipe and reducing the processing accuracy
In addition, if the pipe with a small diameter is processed, such as less than 5mm, excessive clamping force will cause the pipe to be squeezed and deformed, which will directly cause the pipe to be scrapped

Embodiment Construction

[0017] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0018] combine figure 1 and figure 2 As shown, it is a schematic structural diagram and a cross-sectional view of an aerostatic chuck with an adaptive pipe diameter according to an embodiment of the present invention. It includes: a flexible material 3 for contacting with the pipe to be clamped. The inner surface of the flexible material 3 is provided with a sealing chamber 4 for feeding high-pressure gas. The entrance of the sealing chamber 4 is provided with a valve for adjusting the air pressure in the sealing chamber 4. The air pressure regulator adjusts the clamping pressure of the flexible material 3 on the pipe by adjusting the pressure of the high-pressure gas i...

Abstract

The invention relates to the technical field of laser micro-machining and in particular relates to an aerostatic chuck self-adaptive to tube diameters of tubes. The aerostatic chuck self-adaptive to tube diameters of tubes comprises a flexible material contacted with a to-be-clamped tube, wherein a sealing cavity for inflating high-pressure gas is formed outside the inner surface of the flexible material; a gas pressure adjusting piece for adjusting the gas pressure in the sealing cavity is arranged at the inlet of the sealing cavity; and the clamping press force of the flexible material to the tube is adjusted by adjusting the pressure of the high-pressure gas in the sealing cavity. The aerostatic chuck can be self-adaptive to the tube diameter outline of the tube during a clamping process, so that uniform and precise clamping force is provided in the clamping process, and the pressure of the chuck to the tube is reduced to the greatest extent.

Description

technical field [0001] The invention relates to the technical field of laser micromachining, in particular to an aerostatic chuck capable of adapting to the pipe diameter. Background technique [0002] During laser micromachining, clamps are needed to clamp the pipe and drive the pipe to rotate at high speed. In order to ensure reliable clamping, general clamps will exert a large clamping force on the pipe. When it is loosened, springback deformation will occur, destroying the roundness of the pipe and reducing the processing accuracy. In addition, if the pipe with a small diameter is processed, such as less than 5mm, excessive clamping force will cause the pipe to be squeezed and deformed, which will directly cause the pipe to be scrapped. Contents of the invention [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the present invention is that in the laser micromachining of thin-walled pipes, a clamp capable of adapting to the ...
