Abstract

The invention discloses a method and a clamping device for automatically compressing drilling and reaming parts of a porous precision drilling and reaming clamping device. According to the method, a multi-axis unit on the drilling and reaming clamping device is connected with a machine tool spindle during processing; a machine tool Z axis drives the multi-axis unit to slide down along a guide rod; a rectangular spring installed on the guide rod transfers pressure to allow a compressing plate slide down along the guide rod at the same time; when a plastic compressing block on the compressing plate contacts with a workpiece, pressure is gradually exerted by controlling the compressive deformation of the rectangular spring via the machine tool Z axis; a drilling bit drills into a to-be-processed workpiece through positioning of a drill bush; the to-be-processed workpiece is drilled and milled; after drilling and milling, the machine tool Z axis ascends and drives the multi-axis unit to uplift; and through displacement limiting of an elastic hoop, the compressing plate jointly uplifts so as to complete the operations of drilling and milling. The clamping device provided by the invention has the advantages of simple structure, convenient operation, ingenious design, safety and reliability, low equipment cost, capabilities of reducing labor work, quick loading and unloading, automatic clamping, accurate positioning, porous and precise drilling and reaming, one-step operation, etc.
