Quick clamping device for side milling and drilling of carbon fiber sheet

Abstract

The invention discloses a rapid clamping device used for side milling and drilling of a carbon fiber thin board. The rapid clamping device comprises a clamping device body, a locating frame, a plurality of vacuum sucker assemblies and a locating part; the clamping device body is fixed to a machine tool through a bolt, the locating frame is fixed to the top surface of the clamping device body, and the vacuum sucker assemblies are arranged in the locating frame and are connected with a vacuum pump through pipelines; the locating part is hinged to the side edge of the locating frame in a vertical swing mode, the carbon fiber thin board can be completely located through the locating frame and the locating part, the locating frame is fixedly connected with the clamping device body, the locating part is hinged to the clamping device body, and the locating part turns around the axis of a pin. One-time clamping can achieve milling of the side faces of the periphery of a workpiece, and cutting efficiency is greatly improved; the vacuum sucker assemblies can move to regulate the positions on a long kidney-shaped hole supporting transverse beam, and drilling of different positions of the carbon fiber thin board can be conveniently conducted. Therefore, the rapid clamping device has the advantages of being rapid in locating, reliable in clamping, adjustable in drilling position, simple in tool, high in production efficiency and the like.

Description

technical field [0001] The invention relates to a carbon fiber thin plate side milling and drilling processing technology, in particular to a quick clamping device for carbon fiber thin plate side milling and drilling. Background technique [0002] Carbon fiber composite material (CFRP) is a composite material with carbon fiber as a reinforcing material and resin as a matrix. Because of its high specific strength and specific stiffness, good fatigue resistance, and good temperature resistance, it is widely used in the aerospace field. , and has rapidly developed into one of the four major aerospace structural materials after aluminum, steel, and titanium, and drilling and milling are an extremely important process in the processing technology of carbon fiber composite parts. [0003] To improve the processing quality and production efficiency of carbon fiber sheet, the reasonable design of tooling is particularly important. Usually, tooling needs to be designed and manufactu...
