A kind of engraving machine drive shaft as shown in Figure 1 to Figure 3 is optimum embodiment of the present invention, including shaft cabinet
14.14 side of shaft cabinet is fixed with Hybrid stepping motor 8, and the other side is then rotatably connected to shaft big belt wheel and shaft
Small pulley, the shaft small pulley and Hybrid stepping motor 8 are sequentially connected, and pass between the shaft big belt wheel and shaft small pulley
It is dynamic to be connected with shaft synchronous belt 4, shaft 18 is engaged at the shaft big belt wheel center, the shaft 18 runs through shaft cabinet
14 and between shaft cabinet 14 pass through bearing be rotatablely connected.Preferably, there is zanjon between the shaft 18 and shaft cabinet
Ball bearing 20, the deep groove ball bearing 20 are arranged between shaft 18 and shaft cabinet by bearing fixed seat 19.Described turns
Cylinder mounting plate 2 is fixed on the shaft cabinet 14 of axis big belt wheel side, the cylinder 1 passes through cylinder mounting plate 2 and shaft cabinet
14 is fixed.
The shaft 18 is corresponding to be fixed with shaft chuck 5 far from shaft big belt wheel side end face, sets in the shaft chuck 5
Have can in shaft chuck 5 telescopic movable and the folder cylinder 7 locked when flexible by shaft chuck 5.For the ease of folder cylinder 7 flexible
When movement, realizes to match to merge with shaft chuck 5 and the tightening of folder 7 clamping end of cylinder is realized that clamping function, 7 outer peripheral surface of folder cylinder are
Tapered surface, then has inclined-plane of the taper towards cooperation in shaft chuck 5, also along folder 7 peripheral side interval of cylinder on the folder cylinder 7
At least two clamping deformation slots 16 are evenly equipped with, connection folder cylinder 7 in clamping 16 one end of deformation slot clamps the central through hole and folder cylinder 7 of end face
Outer peripheral surface, the other end are located in folder cylinder 7.The end that the clamping deformation slot 16 is located in folder cylinder 7 has through central through hole
With the round deformation hole 15 of folder 7 outer peripheral surface of cylinder.
The side that the shaft cabinet 14 is correspondingly provided with shaft big belt wheel is fixed with cylinder 1, and the cylinder 1 has cylinder
Motion bar 9,9 output end of cylinder motion bar are connected with the flexible dress that folder cylinder 7 can be driven to stretch in shaft chuck 5
Match, through-hole is equipped in the shaft 18, the flexible assembly is arranged in through-hole.
Flexible assembly includes the cylinder connecting rod 11 fixed with 9 output end of cylinder motion bar, the cylinder connecting rod 11
On be connected with sleeve pull rod 12, the sleeve pull rod 12 is fixed with folder 7 end face of cylinder.The cylinder connecting rod 11 is along 18 axis of shaft
It is T-type to section, there is fixation hole, 9 end of cylinder motion bar on the transverse part of the corresponding T-type structure of the cylinder connecting rod 11
Portion has with fixation hole to the positioning pin 10 of cooperation；The sleeve pull rod 12 is that opening is opposite and curved along 18 axial cross section of shaft
Folding part position close to 11 end face of cylinder connecting rod L-type structure, L-type structure include the long straight flange coaxial with shaft 18 and with long straight flange
Flanging connected vertically, longitudinal portion of T-type structure protrude on the inside of the flanging of the L-type structure of sleeve pull rod 12 and with sleeve pull rod 12
