Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the structure of the existing flexible support device is complex, without using multi-point support and improving the rigidity of the supported surface, and to design a method that can not only realize the vacuum adsorption of parts but also realize the displacement of the support column of the multi-point flexible support device. Initialize the work, and at the same time can meet the requirements of the multi-unit integrated control of the flexible support device of the pneumatic transmission control

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] Such as Figure 1-3 shown.

[0022] A pneumatically driven flexible support control device, which includes a vacuum chuck 1 and a hollow piston rod 4, the center of the vacuum chuck 1 is provided with a diaphragm 18 with an opening, the diaphragm 18 is hemispherical, and the opening at the center of the hemisphere It is in the shape of "ten", such as figure 2 , 3 , the vacuum chuck 1 is fixed on the connector 3 through four slotted countersunk screws 2, and one end of the hollow piston rod 4 is sealed and fixed in the connector 3 so as to drive the vacuum chuck 1 to move to the desired location through the connector 3 Adsorb on the workpiece and leave the workpiece after processing. The cavity of the hollow piston rod 4 is connected to the cavity of the vacuum chuck 1 through the opening and closing of the diaphragm 18. The lower end of the ...

Abstract

A flexible supporting control device driven by air pressure comprises a vacuum sucker (1) and a hollow piston rod (4). The flexible supporting control device driven by the air pressure is characterized in that a membrane (18) provided with an opening is arranged at the center of the vacuum sucker (1), the vacuum sucker (1) is fixed to a connecting piece (3), one end of the hollow piston rod (4) isfixed to the interior of the connecting piece (3) in a sealed mode, and the lower end of the hollow piston rod (4) is installed in a piston cylinder (5); and the piston cylinder (5) is fixedly installed on the wall of an air chamber (11), a through hole is formed in the wall of the air chamber (11), a one-way air valve (17) and a rubber pipe connecting piece (10) are installed on the wall of theair chamber (11), and the membrane at the center of the vacuum sucker (1) communicates with the air chamber (11) through the hollow piston rod (4). According to the flexible supporting control devicedriven by the air pressure, the structure is simple, and working is reliable.

Description

technical field [0001] The invention relates to a mechanical processing device, in particular to an array type multi-point flexible support control device used in the processing of weakly rigid parts in the aviation field, in particular to a flexible support control device driven by air pressure. Background technique [0002] At present, in the process of tooling large-scale curved surface parts and thin-walled parts in aviation, due to their own poor rigidity, processing deformation is easy to occur, which leads to the need for backward manual grinding and polishing technology after processing weak rigid parts. Therefore, in order to improve the rigidity of blade processing, some auxiliary supports are installed under the blade to improve its rigidity, and vacuum adsorption is adopted to effectively overcome the problem of excessive deformation of large curved surface parts in traditional multi-point rigid support clamping. In the traditional multi-point flexible support de...
