Driving rotating shaft for engraving machine

Abstract

The invention provides a driving rotating shaft for an engraving machine. The driving rotating shaft comprises a rotating shaft box body, a hybrid stepping motor, a rotating shaft large belt wheel, arotating shaft small belt wheel and a rotating shaft synchronous belt. A rotating shaft is engaged to the center of the rotating shaft large belt wheel, a rotating shaft chuck is fixed to the end faceof the side, away from the rotating shaft large belt wheel, of the rotating shaft, a clamping cylinder which can do stretching-retracting movement in the rotating shaft chuck and is locked by the rotating shaft chuck during stretching-retracting movement is arranged in the rotating shaft chuck, an air cylinder is fixed to the side, corresponding to the rotating shaft large belt wheel, of the rotating shaft box body, the air cylinder is provided with an air cylinder moving rod, the output end of the air cylinder moving rod is connected with a telescopic assembly capable of driving the clampingcylinder to stretch and retract in the rotating shaft chuck, a through hole is formed in the rotating shaft, and the telescopic assembly is arranged in the through hole. The structural design is reasonable, the clamping barrel and the rotating shaft chuck can be driven through acting of the air cylinder to achieve stretching and retracting movement, loosening and clamping of the clamping cylinderare achieved, the clamping effect is good, disengagement is not likely to occur, the production cost is low, machining efficiency is high, the engraving precision is high, and the economic prospect is good.

Description

technical field [0001] The invention relates to the technical field of engraving machine design and production, in particular to a driving shaft for an engraving machine. Background technique [0002] Engraving machine is a kind of drilling and milling combination processing machine. During the engraving process of the engraving machine, it is usually necessary to use a fixture to clamp the workpiece for engraving. At present, the drive shaft of the ordinary engraving machine is driven by a motor. When the click drives the drive shaft to rotate, it is necessary to design a fixture that can effectively clamp the workpiece and connect the fixture to the drive shaft. The mechanical structure is complex and the drive shaft rotates. , the fixture is prone to loosening, resulting in reduced processing efficiency, poor processing accuracy, complex structural design, and high production costs. Contents of the invention [0003] The technical problem to be solved by the present i...
