Title:
摩擦圧接機のばり取り装置
Document Type and Number:
Japanese Patent JP4048290
Kind Code:
B2
Abstract:
A deflashing apparatus is incorporated into a friction welding machine which includes a rotary chuck for chucking a first workpiece, and a carriage having a fixed chuck for chucking a second workpiece and being capable of advancing and retracting in an axial direction. The deflashing apparatus includes a pair of cutter arms, an assistant member, and a bumper fitting. The cutter arms are disposed on the carriage, can swivel, and include a press-cutter joined at the leading end. The press-cutter is dividable into two members, and can envelop the first workpiece. The assistant member is disposed on the carriage, and holds a stopper. The stopper contacts with an end of the second workpiece. The bumper fitting is brought into contact with the assistant member to inhibit the assistant member from retracting. After the first and second workpieces are joined, the rotary chuck releases the first workpiece, and the carriage retracts. In the meantime, the cuter arms swivel to envelop the first workpiece with the press-cutter. When the fixed chuck releases the second workpiece and the assistant member and bumper fitting are brought into contact with each other, the assistant member is stopped ahead of a retract end of the carriage by a stroke of press-cutting. Thereafter, the carriage is retracted by the stroke relatively with respect to the assistant member to deflash the joint between the first and second workpieces with the press-cutter. Thus, the deflashing operation can be completed automatically within the cycle time of the friction welding operation.
