Filed: 1984-09-17
Abstract: PURPOSE:To improve the degree of roundness and prevent the interference of speed change gears with circular-clip and the step difference of a speed change shaft by rotatably supporting the speed change gears onto collars. CONSTITUTION:A speed change gear 6 is rotatably installed onto a speed change shaft consisting of a main shaft 1 and a subshaft 2 arranged in parallel, through collars 7 and 7. Collars 11 and 11 are press-fitted and fixed onto the speed change shaft, and speed change gears 8, 12, and 13 are rotatably supported onto the collars 11 and 11.

IPC: B23D33/02
Filed: 1987-08-03
Abstract: PURPOSE:To make highly accurate and speedy machining possible by supporting a work without lowering a work carrying device till a ram lowers for beginning cutting work with an upper cutting edge interlocked with a lower one. CONSTITUTION:Until a ram 11 lowers to make a movable upper cutting edge 13 approach a work W on a work table 27 (beginning of cutting work), a belt conveyor 35 makes infinitesimal displacement and then stops, and when the movable upper cutting edge 13 gets into a cutting process (after beginning of the cutting work), a shaft 19 rotates to synchronously lower the ram 11 through connecting rods 17, 57 for cutting a work W. Thus until the cutting edge 13 abuts on the work W on a fixed lower cutting edge 7, the work W is supported on the belt conveyor 35 to be prevented from a dangle caused by its dead weight. The highly accurate and speedily cutting work can be therefore performed.
