Abstract

The invention discloses a synchronous clamping eccentricity detection device for a circular workpiece. The synchronous clamping eccentricity detection device comprises a detection device body and a clamping-rotating mechanism, the detection device body is arranged on the clamping-rotating mechanism, the clamping-rotating mechanism comprises a cylindrical annular mounting base, a clamping area is formed in an inner cavity of the annular mounting base, and the detection device body is arranged around the center line of the annular mounting base; and the detection device body comprises a slidingpart and a detection part, the sliding part is movably inserted into the cylinder wall of the annular installation base in a penetrating mode, the detection part is fixedly installed on the sliding part, and an alignment mark is arranged on the detection part. According to the synchronous clamping eccentricity detection device for the circular workpiece, after that the cylindrical workpiece to bewelded is fixed, whether the cylindrical workpiece is offset can be determined, a clamping cylinder is adjusted in time, the rotating stability of the cylindrical workpiece during welding is ensured,and the welding quality is improved.

Description

technical field [0001] The invention relates to a detection device, in particular to a circular workpiece synchronous clamping eccentricity detection device. Background technique [0002] Friction stir welding refers to the use of the heat generated by the friction between the high-speed rotating welding tool and the workpiece to locally melt the welded material. When the welding tool moves forward along the welding interface, the plasticized material is under the action of the rotating friction of the welding tool. It flows from the front of the welding tool to the rear, and forms a dense solid-phase weld under the extrusion of the welding tool. When using friction stir welding to weld two cylindrical workpieces to be welded, the ends of the two cylindrical workpieces to be welded should be pressed tightly, and the two cylindrical workpieces to be welded are fixed by a clamping device, and the welding tool Fixed, the welding stirring head extends into the seam from the out...
