Summary of the invention
Purpose of the present invention is exactly the weak point in the background technology, provides a kind of by motor-driven broaching machine.
For achieving the above object, the present invention adopts following technical scheme: a kind of by motor-driven broaching machine, comprise lathe bed, slide carriage and folder cutter hub, folder cutter hub and slide carriage are affixed, slide carriage and lathe bed laterally or longitudinally guiding be connected, the lathe bed upper end is provided with transmission case, the lathe bed front side vertically is respectively equipped with two rhizoid bars, and the screw mandrel upper and lower side is connected with lathe bed by bearing block respectively, its upper end is stretched into respectively in the transmission case, described slide carriage is connected with screw mandrel guiding respectively, and the lathe bed rear side is provided with motor, and it is interior and stretch into screw mandrel that an end is in transmission connection in the transmission case that the power output shaft end of motor vertically stretches into transmission case.
For a kind of optimization of the present invention, the power output shaft end of motor is connected with driving pulley in the transmission case, and screw mandrel stretches into the interior end of transmission case and is connected with driven pulley, and driving pulley is in transmission connection by Timing Belt and driven pulley.
For a kind of optimization of the present invention, described transmission case is hermetically-sealed construction.
For a kind of optimization of the present invention, described slide carriage rear side is connected with screw rod transmission by screw pair respectively.
The present invention compares with background technology, has compact conformation, reasonable, and whole equipment occupation of land space is little; Motor is by toothed belt transmission, thereby driving force is distributed to two rhizoid thick sticks synchronously, and having guaranteed the synchronism of two rhizoid thick sticks, and its driving force loss is little, and environmental protection and energy saving, operating noise are little; The double lead-screw design provides stable pulling force, and the broaching center is arranged at the mid point of double lead-screw line, thereby the protection leading screw has been got rid of again lathe stress and the potential problems such as pulling force skew, and this has improved machining accuracy from the machine stress principle; Transmission case is arranged at lathe bed top, and such design can prevent comprehensively that the intrusion of smear metal and cooling fluid from damaging driver part; The double lead-screw two ends are installed in the upper and lower side of lathe bed, drive stroke overlapping with the broaching stroke, do not need high-base, reduce the lathe total height, make the lathe profile small and exquisite.
