Embodiment Construction

[0022] The specific implementation manners of the present invention will be described in detail below in conjunction with the technical solutions and accompanying drawings.

[0023] The processing system includes a tool 1, a workpiece 2 and a servo feed system. The tool 1 is used for milling a workpiece 2; the workpiece 2 is a material to be processed.

[0024] The dynamic pressure system includes a roller 3 , a shaft 4 , lubricating oil 5 , a guide rail 6 , a slide table 7 , an oil supply groove 8 and a flexible membrane 9 . There is a wedge-shaped gap between the roller 3 and the workpiece 2 . The shaft 4 drives the roller 3 to rotate through the motor, the roller 3 is immersed in the lubricating oil 5, the roller 3 rotates at a certain speed, and forms a relative motion with the surface of the workpiece 2 . Under the control of the servo feed system, the oil supply tank 8 can drive the oil supply tank 8 to move in the three directions of X, Y and Z. The lubricating oil 5...

Abstract

The invention relates to a dynamic pressure supporting device and a method for thin-wall part processing, and belongs to the technical field of precision processing and supporting. The dynamic pressure supporting device comprises a processing system and a dynamic pressure system, wherein a cutter of the processing system is positioned at a processing side of a workpiece and connected with a servofeeding system, and the workpiece is positioned between the cutter and the dynamic pressure system; a roller in the dynamic pressure system is positioned at the supporting side of the workpiece and immersed in lubricating oil; a wedge-shaped gap is formed between the roller and the workpiece; the roller is driven to rotate by a motor to form a dynamic pressure oil film on the surface of the workpiece, so the flexible support for the workpiece is realized; the lubricating oil is injected into an oil supply tank through an oil supply port on the oil supply tank and sealed by a flexible film. According to the invention, the workpiece can be separated from the roller by the dynamic pressure oil film, the roller does not contact with the workpiece directly, so scratches are not generated on thesurface of the workpiece. Meanwhile, the oil film has strong vibration absorption, which can effectively inhibit chatter during machining and improve the surface quality of the machined workpiece.

Description

technical field [0001] The invention belongs to the technical field of precision machining support, and relates to a dynamic pressure support device and method for processing thin-walled parts. Background technique [0002] In order to reduce the weight of the aircraft, enable the aircraft to carry more materials, reduce fuel consumption, and improve the overall performance of the aircraft, thin-walled parts, such as the skin of the aircraft, are widely used on the aircraft. The rigidity of thin-walled parts is low, and it is easy to be deformed by force during processing, and it is easy to generate chatter during processing. Therefore, the processing of thin-walled parts is a difficult problem in the field of aerospace manufacturing. [0003] At present, the traditional thin-walled parts processing generally adopts the method of chemical milling. Chemical milling is to use the principle of chemical reaction to remove material, and can get the required size and shape of pa...
