A replacement device of a processing apparatus includes a gripping device having a single first support member positionally fixed, a first gripping portion provided on the first support member to grip a holder not to rotate in a releasing direction when the processing member is removed from the holder, and a second gripping portion provided on the first support member apart from the first gripping portion to grip the holder not to rotate in a restricting direction when the processing member is attached to the holder, and a holding device having a single movable second support member, plural first holding portions provided on the second support member to respectively accommodate the processing member removed from the holder, and plural second holding portions provided on the second support member apart from the first holding portions to respectively accommodate the processing member that is to be attached to the holder.

Processing apparatus

In a friction stir welding apparatus that can control a penetrating position of a probe with respect to a processing target member to an optimum position at a time of friction stir welding by detecting a wear volume and a tip position of the probe, as a drive mechanism moves down a holder having a coefficient of thermal expansion larger than that of the probe and holding the probe, a detector can freely detect a length of a member including the holder and the probe, and a probe detection mechanism can freely detect a tip length, which is the length of the member of only the probe.

Friction stir welding apparatus

A friction stir welding apparatus includes a displacement detecting device that detects displacement of a welding tool caused by deformation of a fitting jig, at the time of performing friction stir welding in which an arm to which the fitting jig fitted with the welding tool is fixed is moved to move the welding tool with respect to the processing target member. The fitting jig can be deformed more than the arm at the time of performing friction stir welding. The displacement detecting device has a displacement sensor fixed to the welding tool, and a reference member fixed to a fixing portion between the fitting jig and the arm to provide a reference position for detecting the displacement to the displacement sensor.

A friction stir welding apparatus having a new cooling system that can cool a portion required to be cooled accurately and uniformly with a simple configuration, while suppressing unnecessary thermal expansion of a mounting jig includes a holding mechanismhaving a holding membermovable with respect to a processing target member W so as to freely hold the processing target member W, in which the holding memberand a portion of a mounting jigthat can freely face the holding memberbecome paired, and a coolant supply source S that can freely supply a coolant to the paired holding memberand the portion of the mounting jig
