The vacuum cavity comprises a rear baffle, a front baffle, a right baffle, a left baffle, a bottom plate, an upper structure beam, a transverse structure beam, a lower structure beam, a transverse division plate, a straight division plate, an upper sliding rail, a lower sliding rail, a supporting rod, a cutting bristle block, a transmission chain disc and a transferring chain; the rear baffle, the front baffle, the right baffle, the left baffle and the bottom plate form a sealedvacuum cavity structure; the transverse structure beam, the upper structure beam and the lower structure beam are fixed; the transverse division plate is connected with the straight division plate; the transverse structure beam is connected with the right baffle and the left baffle; the upper structure beam is provided with the upper sliding rail, and the lower structure beam is provided with thelower sliding rail; the cutting bristle block is arranged on the supporting rod; the bottom of the supporting rod movably makes contact with the upper sliding rail and the lower sliding rail; the transmission chain disc is in transmission connection with the transferring chain; and the transferring chain drives the supporting rod and the cutting bristle block to move. The vacuum cavity of the multi-cavity structure is reasonable in structure, high in strength and good in stability and is provided with a plurality of inner cavity structures, so that the vacuum adsorbing function of a working area is achieved.

Description

technical field [0001] The invention relates to a vacuum cavity, in particular to a vacuum cavity with a multi-cavity structure, which belongs to the technical field of cutting materials. Background technique [0002] The existing vacuum chamber structure, the main body is two flat side plates, a front end plate, a rear end plate and a flat bottom plate welded to each other. strength between. [0003] During the use of the above-mentioned vacuum chamber, when the negative pressure is large, the side plate is prone to local elastic deformation, which affects the loosening of the transmission chain. It is easy to be pulled off; and it is difficult to ensure the accuracy of cutting, and it is difficult to assemble. [0004] The publication date is March 02, 2006, and the publication number is 205060659U in the Chinese patent, which discloses a utility model patent named "Cutting Machine Vacuum Adsorption Mechanism". This patent includes a vacuum adsorption mechanism body loc...
