Apparatus for double-position automatically circular milling of crank shaft semi-circle keyway

Abstract

The invention discloses an apparatus for double-position automatically circular milling of a crank shaft semi-circle keyway. The apparatus comprises a servo sliding stable, workpiece positioning mechanisms, pneumatic pressing mechanisms, pneumatic locking mechanisms, pneumatic ejection mechanisms and an electrical control system; the apparatus is characterized in that a left processing position and a right processing position are symmetrically arranged at the servo table; and a semi-circle keyway milling cutter is arranged between the two processing positions, and workpiece positioning plates, pneumatic clamping mechanisms, pneumatic clamping mechanisms, the pneumatic locking mechanisms and the pneumatic ejection mechanisms are respectively arranged at the two positioning positions. Except that the workpieces are manually mounted and clamping buttons are clicked, the other parts sequentially clamp, process and detach the workpieces under the control of the electrical control system, and the process is circularly operated until the workpieces are not clamped. In the working process, the labor intensity of the workers is obviously reduced, the working efficiency is improved, and the requirement of mass production is applicable.

Description

technical field [0001] The invention relates to the technical field of mechanical processing of mechanical parts, in particular to a device for milling semicircular key grooves of crankshafts of small gasoline engines. Background technique [0002] The large demand for portable garden machinery and plant protection machinery in the domestic and foreign markets has driven the demand for processing parts. Among them, the semicircular keyway milling of the crankshaft, which is the core part of the power part, is currently used for general-purpose milling machines and ordinary fixtures. Manual clamping , manual feeding and other manual operations for keyway milling, the production efficiency is low, the labor intensity is high, the processing accuracy is low, and it cannot meet the needs of mass production. Therefore, it is urgent to invent an efficient and reliable semicircular keyway milling device. The production status of milling semicircular keyway can improve production ef...
