Abstract
An improvement in a continuous flexible drive, preferably a chain, broaching machine in which a transmission, preferably a worm-worm gear speed reducer transmission is connected to a driving motor and to a sprocket, or a pair of sprockets, carried by a drive shaft which in turn is connected by chain means to a sprocket or a pair of sprockets on a shaft which drives the chain means of a chain broaching machine. The input unit including the transmission is designed in conformity with the drive end of the broaching machine to permit placement of input drive mechanism in different positions so as to provide freedom in placement of a plurality of broaching machines without interfering with each other.
Claims14
A continuous or chain broaching machine comprising an elongated frame, a fixture drive shaft having fixture drive sprocket means adjacent one end of the frame, an idler shaft having driven sprocket means adjacent the other end of said frame, fixture drive chain means trained over said sprockets, a tunnel extending longitudinally of said frame through which one run of said chain means extends, driven sprocket means on said fixture drive shaft, a separate, self-contained power input assembly having a unitary support structure separate from said elongated frame but connected thereto in a selected position, said assembly comprising motor means, speed reducer means connected to said motor means, said speed reducer means having output sprocket means, the output sprocket means of said speed reducer means being aligned with the driven sprocket means on said fixture drive shaft when said unitary support structure is connected to said broaching machine frame in said selected position, and input chain means connecting the output sprocket means of said speed reducer means to the driven sprocket means on said fixture drive shaft.
A chain broaching machine comprising an elongated frame, a fixture drive shaft adjacent one end of said frame, a fixture driving sprocket means on said fixture drive shaft, an idler shaft adjacent the other end of said frame, sprocket means on said idler shaft, a fixture drive chain means trained over the sprockets, a tunnel extending longitudinally of the frame through which one run of the chain means extends, driven sprocket means on said fixture drive shaft, and a power input assembly for driving said driven sprocket means, said frame comprising a side plate having a horizontal top edge extending for the length of said tunnel, an elongated strip connected to said side plate with an upper edge thereof spaced horizontally from the top edge of said plate to define therewith an elongated trough, an elongated tunnel cover supporting bar connected to the edges of said plate and strip and forming a manifold extending longitudinally of said trough, a connection for supplying coolant to said manifold, and passage means spaced longitudinally of said manifold for connection of lines for leading coolant to broaching means spaced longitudinally within said tunnel.
