Abstract

The invention discloses a method for clamping a multi-hole part through a universal vacuum platform. The method comprises the following steps that holes are formed in one face of the part to be machined; the holes are filled with gypsum; after the gypsum is solidified, the gypsum is scraped to be flat, so that the filled faces of hole openings of the gypsum are flush with a surface to be adsorbed; the hole openings are sealed through adhesive tape; one surface of the part to be machined is arranged on the universal vacuum platform through vacuum adsorption, and the other face of the part to be machined is machined after vacuum adsorption. Thus, no avoided portion needs to be considered in the process that vacuum adsorption is conducted on the part through the universal vacuum platform, the adsorption area of the whole part is increased, the vacuum adsorption strength is enhanced, and manufacturability of the part is enhanced.

Description

technical field [0001] The invention relates to the technical field of numerical control machining of structural parts, in particular to a method for clamping porous parts using a general vacuum platform. [0002] Background technique [0003] In the field of CNC machining, especially in the CNC machining of aircraft structural parts, in order to improve the stability of parts processing, special vacuum milling clamps are usually used for vacuum adsorption clamping and positioning processing technology to improve the machining accuracy of parts. rigidity. Because it is a porous part, holes of various sizes are distributed in different positions. Therefore, in the process of using a general-purpose vacuum platform to adsorb the part, in order not to leak air, it is necessary to consider the avoidance position, that is, set up a special area on the tooling to avoid Open the opening position of the part, which brings inconvenience to the processing of the part. [0004] Co...
