Embodiment 1

[0040] Attached below Figure 1-Figure 4 The present invention is described in detail, specifically, the structure is as follows:

[0041] This embodiment provides an auxiliary supporting device for processing thin-walled cylindrical parts, including an outer airbag 1, an inner airbag 2, an intake valve 3, and an exhaust valve 4, wherein the inner airbag 2 is arranged on the outer airbag 1 interior. Both the outer layer airbag 1 and the inner layer airbag 2 are annular airbags whose length is compatible with the thin-walled cylindrical part 10 to be processed. In the initial state, the supporting device corresponding to the size of the thin-walled cylindrical part 10 is placed on the thin-walled cylindrical part in an uninflated state. In the inner cavity structure of the barrel 10.

[0042] The outer wall of the inner layer airbag 2 is equipped with a valve core 5 for connecting with an inflation and deflation and air pressure detection device. An intake valve 3 and an exh...

Embodiment 2

[0049] This embodiment provides an auxiliary support system for processing thin-walled cylindrical parts, such as Figure 5 As shown, it includes the auxiliary supporting device described in Embodiment 1, the inflation nozzle 6, the hose 7, the air pressure control valve 8, the pumping dual-purpose vacuum pump 9, the air gauge 11, and the computer 12. One end of the inflation nozzle 6 is connected to the valve core 5 The other end of the inflation nozzle 6 is connected to the pumping dual-purpose vacuum pump 9 through the hose 7. The hose 7 is equipped with an air pressure control valve 8 and an air gauge 11. The air gauge 11 is connected to a computer 12 for real-time data transmission. In this embodiment, the hose 7 is a high-pressure hose.

[0050] The air pressure control valve 8 can independently set a suitable upper air pressure value. When the pressure of the filling medium in the support device reaches the upper limit of the set air pressure, the air pressure control ...

Abstract

The invention discloses an auxiliary supporting device, system and method for thin-walled barrel piece machining. Machining deformation of a thin-walled barrel piece is reduced, vibration during machining is reduced, machining errors are decreased, and the machining precision is improved; and the problem that a common single-layer airbag is not suitable for supporting a thin-walled barrel piece ofwhich the surface is uneven is solved. The structure is simple, disassembling and assembling are convenient, and the auxiliary supporting device can be closely attached to the surface of the thin-walled barrel piece in a supporting mode. According to the technical scheme, an inner layer airbag and an outer layer airbag which are sleeved together are included, a plurality of air inlet valves and air outlet valves are installed between the inner layer airbag and the outer layer airbag, and under control of the air inlet valves, the inner layer airbag and the outer layer airbag expand in sequence so that the to-be-machined thin-walled barrel piece can be supported.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to an auxiliary support device, system and method for processing thin-walled cylindrical parts. Background technique [0002] Problems such as processing deformation and chatter are prone to occur during the processing of thin-walled cylindrical parts. Therefore, in order to improve the machining accuracy of thin-walled cylindrical parts, it is particularly important to provide auxiliary support for thin-walled cylindrical parts. The inventors found that in the prior art, the thin-walled cylindrical piece is supported by the airbag, but the supporting effect on the thin-walled cylindrical piece cannot meet the requirement. [0003] For example, the prior art discloses an airbag clamp, which supports the outer surface of the thin-walled cylindrical part by inflating the airbag, and improves the rigidity of the thin-walled cylindrical part by means of the airbag support. The lim...
