Abstract:
A deflashing apparatus for a friction welding machine,the friction welding machine including:a base;a head stock disposed on the base, having a rotary chuck for holding a first workpiece, and a main shaft assembled therein, the main shaft being capable of quickly stopping; anda carriage disposed on the base, having a fixed chuck for holding a second workpiece so as to be concentric with an axis of the first workpiece, and being capable of advancing and retracting in the direction of the axis by thrust force applying means;the deflashing apparatus comprising:a pair of cutter arms disposed on the carriage of said friction welding machine, having a leading end, being capable of swiveling, and including a press-cutter, the press-cutter joined at the leading end, being dividable into two members and being capable of enveloping the first workpiece;an assistant member disposed on the carriage of said friction welding machine, and holding a stopper, the stopper contacting with an end of the second workpiece; anda bumper fitting disposed on the base of said friction welding machine, and being brought into contact with the assistant member to inhibit the assistant member from retracting;whereby the assistant member is stopped ahead of a retract end of the carriage by a stroke of press-cutting when the fixed chuck is deactivated to release the second workpiece from the chucking and the assistant member and bumper fitting are brought into contact with each other, and thereafter the carriage with the pair of cutter arms disposed thereon is retracted relatively with respect to the assistant member by the stroke of press-cutting to deflash the joint between the first and second workpieces with the press-cutter.
