Flexible clamp platform used for milling of gantry type five-coordinate metal plate numerical control milling machine

Abstract

The invention belongs to the technical field of process equipment, and relates to a flexible clamp platform used for milling of a gantry type five-coordinate metal plate numerical control milling machine. The device comprises a fixed type base, a high-precision tool setting datum hole, longitudinal sliding rods, longitudinal sliding rails, a suction cup base, a supporting rod support, a supportingrod, a vacuum suction cup and transverse sliding rail grooves; the fixed type base is placed on a five-coordinate machine tool platform, two transverse sliding rail grooves with size graduated linesand the multiple longitudinal sliding rods with the size graduated lines are arranged, the longitudinal siding rods are arranged on the transverse sliding rail grooves, the longitudinal sliding railsare arranged on the longitudinal sliding rods, the suction cup base is arranged on the longitudinal sliding rails, the bottom end of the supporting rod support is in screw joint to the suction cup base, the supporting rod is screwed into a thread through hole of the supporting rod support, and can vertically move up and down, and the vacuum suction cup is fixed to the top end of the supporting rod, and can swing at any angle in a 360-degree manner to be fixed and is used for tightly absorbing the part to be milled. The platform is wide in application range, and rapid in positioning, and the milling precision is not lower than that of an electric transmission automatic flexible clamp imported from abroad.

Description

technical field [0001] The invention belongs to the technical field of process equipment, and relates to a flexible fixture platform for milling and cutting of a gantry-type five-coordinate sheet metal numerical control milling machine. Background technique [0002] Covering parts that directly affect the aerodynamic layout on the outer surface of the aircraft are usually called skin parts. Specifically, skin parts refer to the thin plate parts that constitute the aerodynamic shape of the aircraft and the foreskin of the internal structure. Skinned parts withstand and transmit airflow loads. From the perspective of appearance and structure, skinned parts have the characteristics of thin plates, gentle curvature changes, and large dimensions. The conventional processing method is to manually draw the edge line of the part according to the edge line of the drawing die and then manually cut it according to the line. During the manual scribing process, there will be movement i...

Problems solved by technology

Due to the high price of vacuum flexible fixtures that come with CNC machine tools, although the automation and telex control capabilities have been realized, it is still necessary to use the part digital model to generate the milling fixture profile.

Therefore, the time-consuming period is long, which affects the processing efficiency and processing cost
