Abstract

The invention discloses a vacuum clamping device and method, and belongs to the technical field of clamping. The vacuum clamping device comprises an adsorption plate, a vacuum adsorption mechanism, a plurality of cushion blocks and a sealing mechanism. A plurality of grooves are formed in the adsorption plate. Vent holes are formed in the plurality of grooves. The vacuum adsorption mechanism communicates with the vent holes formed in the adsorption plate. One ends of the cushion blocks are movably arranged in the plurality of grooves. The arrangement positions of the cushion blocks on the adsorption plate are matched with the shape of a workpiece. The sealing mechanism is connected with the other ends of the plurality of cushion blocks. The sealing mechanism forms a closed space on the supporting face composed of the cushion blocks. The shape of the closed space is matched with the shape of the workpiece. The vacuum clamping device and method can be suitable for clamping thin plate type parts of various shapes and sizes, adjustability is high, free combination is achieved, universality is high, use is flexible, and the manufacturing cost is low.

Description

technical field

[0001] The invention relates to the field of clamping technology, in particular to a vacuum clamping device and method. Background technique

[0002] Thin-walled frame plate parts are a common part in aerospace products. There are reinforcing ribs and lightening grooves of different shapes distributed on the surface of this type of parts, which is difficult to process and easy to deform. Using vacuum suction cups for clamping can solve the problem of deformation and improve production efficiency. Since the vacuum suction cups on the market cannot absorb such parts, it is necessary to design a new vacuum suction cup clamping device for clamping such parts. Contents of the invention

[0003] The invention provides a vacuum clamping device and method, which solves or partially solves the technical problem in the prior art that a vacuum chuck cannot absorb thin-walled frame-shaped plate parts.

[0004] In order to solve the above-mentioned technical problems,...
