FRICTION SPOT JOINING DEVICE AND FRICTION SPOT JOINING METHOD

A friction spot joining device (1) configured to carry out friction spot joining of a pair of plates (W1, W2) includes an advance-retreat drive (M1) configured to advance and retreat a tool (11) to/from the plates (W1, W2), a rotation drive (M2) configured to rotate the tool (11), and a controller (...

Beschreibung
Zusammenfassung:	A friction spot joining device (1) configured to carry out friction spot joining of a pair of plates (W1, W2) includes an advance-retreat drive (M1) configured to advance and retreat a tool (11) to/from the plates (W1, W2), a rotation drive (M2) configured to rotate the tool (11), and a controller (4) configured to control the advance-retreat drive (M1) and the rotation drive (M2). The controller (4) executes a joining control in which the tool (11) is caused to give pressure to the plates (W1, W2) while the tool (11) is rotated so that the tool (11) is pushed into the plates (W1, W2), and a separating control in which the tool (11) is separated from the plates (W1, W2) when an integrated value (P= I D ×T) calculated using a current value (I D ) of the rotation drive (M2) during the joining control and a driving period of time (T) during the joining control is determined to be reached a target value.
