Embodiment Construction

[0012] From the perspective of fixtures, it can effectively reduce clamping deformation, avoid chattering of parts during processing, and ensure the machining accuracy and surface quality of workpieces; and one fixture can clamp multiple products, greatly reducing manufacturing costs.

[0013] Such as figure 1 As shown, the vacuum chuck for aviation thin plate processing includes a fixture body 3 and a sealing strip 2. The upper surface of the fixture body 3 is provided with grooves at equal intervals, and the sealing strip 2 is embedded in the groove, which can be processed according to the product 1. The shape embeds the corresponding sealing strip in the groove, and the central part of the fixture body 3 is opened with a through air hole 4 in the axial direction, and the bottom end of the air hole 4 is connected to the compressed air machine through the air pipe.

[0014] In specific application, the processed product 1 is placed on the sealing strip, the compressed air mac...

Abstract

The invention relates to a vacuum chuck for processing of aeronautical laminas. The vacuum chuck comprises a fixture body and seal strips, wherein grooves are formed in the upper surface of the fixture body; the seal strips are embedded in the grooves; a feed-through aspirating hole is axially formed in the center of the fixture body; and the bottom end of the aspirating hole is connected to an air compressor through an air pipe. The tool fixture reduces clamping deformation effectively, avoids oscillation when parts are processed, and guarantees processing precision and surface quality of a workpiece; and moreover, one tool fixture realizes clamping of various products, so that manufacturing cost is reduced greatly.

Description

technical field [0001] The invention relates to a vacuum sucker for aviation thin plate processing, which belongs to the technical field of precision machining equipment. Background technique [0002] Aeronautical parts are mostly thin-walled parts with large size and large machining allowance. Under the influence of cutting force, cutting heat, cutting chatter and other factors, it is easy to cause machining changes, and it is difficult to control machining accuracy and improve machining efficiency. The problems of processing deformation and processing efficiency have become difficult problems in the processing of thin-walled structures. [0003] For aviation thin-walled parts, it is necessary to fully optimize high-speed machine tools, cutting tools, processes, and fixtures to reduce cutting heat and clamping deformation. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a vacuum chuck f...
