Vacuum adsorption clamping system applied to thin aluminum product part machining

Abstract

The invention relates to the field of part machining, in particular to a vacuum adsorption clamping system applied to thin aluminum product part machining. The system is composed of a large table topdevice and a small table top device, the two table top devices are spliced through hinges, grooves are formed in the table top of a vacuum adsorption device in a criss-cross mode and communicate withinternal pipelines of the table top devices through a plurality of screw holes, sealing strips are embedded into the table top grooves to form a closed region, the screw holes except the area are sealed through special nuts, a vacuum pump machine is connected with the pipelines inside the vacuum table top devices through nylon pipelines, so that vacuum negative pressure generated by the vacuum pump is transferred to the closed area through the pipelines, and an oil liquid filtering device is additionally arranged at the front end of the vacuum pump. According to the vacuum adsorption clampingsystem, clamping marks cannot be generated on the surface of a product, so that the machining precision is guaranteed; and due to the fact that the table top devices of the vacuum adsorption clampingsystem are further provided with a plurality of table top device bodies with different groove shapes and a plurality of different groove-shaped sealing rubber pads, even the rubber pads perforated according to needs can be selected to adsorb parts for machining.

Description

technical field [0001] The invention relates to the field of part processing, in particular to a vacuum adsorption clamping system used in the processing of thin aluminum parts. Background technique [0002] The smoke deflector series parts are thin and made of aluminum alloy. Using traditional fixtures, it is easy to leave indentations on the surface of the parts, and the processing process needs to replace the pressure plate, resulting in discontinuous processing, so it is impossible to use traditional fixtures or magnetic Attachment fixes the parts to complete the CNC forming process of the parts. Therefore, a clamping system that does not produce pinch marks on the product surface and can ensure machining accuracy becomes necessary. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a vacuum adsorption clamping system that does not produce pinch marks on the product surface during the processing of thin alumin...
