The utility model discloses a simple keyway
processing device which comprises a driving motor, a worm and gear
reducer, a
crank, a connecting rod, a guide sleeve, a pull rod and a base, the guide sleeve and the worm and gear
reducer are fixed on the base, an input shaft of the worm and gear
reducer is connected with the driving motor, and an output shaft of the worm and gear reducer is connected with the
crank. The pull rod is slidably inserted into a guide hole of the guide sleeve, one end of the pull rod is provided with the cutter, the other end of the pull rod is rotatably connected with the
tail end of the connecting rod, and the head end of the connecting rod is connected with an output shaft of the worm and gear reducer through a
crank. The rotary motion of the output shaft of the worm and gear speed reducer is converted into the
linear motion of the pull rod through the crank and the connecting rod, the key groove is machined in the workpiece through the cutter installed on the pull rod, the structure is simple, cost is low, the
machining cost of small-batch parts can be reduced, and the
machining efficiency is improved. And the key groove
machining requirements of small enterprises are met.
