Detailed description of the invention
Below in conjunction with brief description of the drawings the specific embodiment of the present invention.As shown in Figures 1 to 9: the synchronous knife machining mechanism of a kind of belt-type transmission main shaft, comprise the main shaft 1 and the rotation motor 2 that are arranged in frame, the output of rotation motor 2 rotates by the secondary drive shaft 1 of belt transmission, is also provided with the return spring group 13 that main shaft 1 can be pushed up back to original position in main shaft 1 upper end, above main shaft 1, be provided with first connecting rod 3 of forging a knife, this first connecting rod 3 of forging a knife comprises horizontally disposed horizon bar 4 and the tilting bar 11 being obliquely installed, and angled being fixedly connected with between horizon bar 4 and tilting bar 11, the coupling part of the two is rotatably supported in frame by rotating shaft, also be provided with manual loose cutter cylinder 12 on the top of frame 1, the apical position of the working end of this manual loose cutter cylinder 12 and tilting bar 11 matches, also be provided with inclined-plane 5 at horizon bar 4 away from one end of this rotating shaft, lower one end, this inclined-plane 5 is towards roller 9, higher the closer to the inclined-plane, outside 5 of horizon bar 4, also be provided with the roller 9 matching with the top of main shaft 1 at the middle part of horizon bar 4, on 5 upper surfaces, inclined-plane, be also provided with down-pressure roller 6, this down-pressure roller 6 is rotatably supported in the second top of forging a knife connecting rod 7, and second other end and the 3rd of forging a knife connecting rod 7 is forged a knife, connecting rod 8 is fixedly connected with, and the two in coupling part also by rotating shaft support in frame, second connecting rod 7 and the 3rd connecting rod 8 of forging a knife of forging a knife can rotate with respect to frame jointly, and the 3rd end of forging a knife connecting rod 8 also matches by trundle and cam 10, and this cam 10 drives by motor.
The course of work of the synchronous knife machining mechanism of belt-type transmission main shaft of the embodiment of the present invention is as follows: cam 10 rotates under the drive of motor, when the larger part and the 3rd of cam 10 diameters is forged a knife the trundle of connecting rod 8 bottoms while contacting, the 3rd forge a knife connecting rod 8 can and second connecting rod 7 of forging a knife together rotate, the second down-pressure roller 6 of forging a knife connecting rod 7 tops can apply downward pressure to the inclined-plane 5 of contact with it in the process of rotating, thereby drive the horizon bar 4 at 5 places, inclined-plane to swing, at horizon bar 4 in lower swing, be arranged on roller 9 motion thereupon at horizon bar 4 middle parts, main shaft 1 is pressed down, realize the action of main shaft knife loosening, in the time that the less part of cam 10 diameters contacts with the 3rd trundle of forging a knife connecting rod 8, above-mentioned action reversed is carried out, and roller 9 no longer applies downward pressure to main shaft 1, and under the effect of return spring group 13, main shaft 1 moves up to original position again, when above-mentioned action, rotation motor 2 drives main shaft 1 to rotate by belt pulley transmission, and these two actions coordinate to be carried out, and realizes loose cutter, folder cutter, the tool changing action of main shaft,
If while not needing to use mechanical tool magazine tool changing or synchronously moving mechanism to occur to damage ring, can also control manual loose cutter cylinder 12 and work, its working end is descending, drives first connecting rod 3 of forging a knife to swing by promoting the termination of tilting bar 11, and then roller 9 presses down main shaft 1, realize loose cutter action; After tool changing or fault are got rid of, reclaim the working end of manual loose cutter cylinder 12, and under the effect of return spring group 13, main shaft moves up to original position again.
The feature of this kind of synchronous knife machining mechanism maximum of synchronous knife machining mechanism is: the transmission mechanism of its inside first connecting rod 3, second connecting rod 7 and the 3rd connecting rod 8 of forging a knife of forging a knife of forging a knife all does the swing of circular arc, pressing action by down-pressure roller 6 to inclined-plane 5, finally realizes the longitudinal application of force requirement of roller 9 to main shaft 1.
