Flexible rapid adjustment type vacuum suction cup suitable for energetic material machining

Abstract

The invention provides a flexible rapid adjustment type vacuum suction cup capable of rapidly adapting to vacuum tight absorption and reliable clamping of workpieces of different sizes and suitable for energetic material machining. The vacuum suction cup comprises an absorption part and a positioning part which are connected; a center air guide hole is formed in the center of the surface of the absorption part, multiple round grooves are formed in the surface of the absorption part, the multiple round grooves are concentrically arranged with the center air guide hole as the round center, the upper portions of the multiple round grooves are located on the same horizontal plane, multiple thread through holes communicated with the center air guide holes are formed in the side wall of the absorption part, a set screw is arranged at the end, away from the center air guide hole, of each thread through hole in the thread through holes, ventilation holes the same with the round grooves in number are formed above each thread through hole in the multiple thread through holes in a communication manner, each ventilation hole is formed in the bottom of the corresponding round groove in a one-to-one correspondence manner, and a pipe joint communicated with the center air guide hole is formed on the side wall of the positioning part.

Description

technical field [0001] The invention relates to the technical field of mechanical processing of energetic materials and tooling design, in particular to a flexible and quick-adjustable vacuum chuck suitable for processing energetic materials. Background technique [0002] In view of the special requirements for the reliability of clamping of some thin sheet energetic material parts, conventional metal clamping methods (such as chuck clamping, adhesion positioning, etc., which may damage or deface the workpiece) are difficult to promote and apply in this field. [0003] Vacuum adsorption technology is very beneficial to the effective and reliable clamping of thin sheet energetic material parts in the process of machining, and has obvious advantages in preventing product pinching and easy precision adjustment. Vacuum adsorption tooling uses the difference in atmospheric pressure and the vacuum inside the vacuum chuck to form a pressure difference. Through this pressure differe...
