The invention discloses a positioning and clamping device for an all-hydraulic-driven numerical-control friction stitch welding machine. The positioning and clamping device comprises two fixed supporting structures arranged in left-right symmetry, and the two fixed supporting structures are fixedly connected through two upper straining beams arranged in front-back symmetry and two lower grid beams arranged in front-back symmetry. The fixed supporting structures stretch across a pipeline, and each fixed supporting structure is provided with an inner side plate and an outer side plate. A clamping mechanism is arranged between every two side plates. Each clamping mechanism comprises arc fixing blocks matched with the pipeline and two clamping arms symmetrically arranged on the two sides of the pipeline, wherein the middle of each clamping arm is connected with a hinge shaft, the lower portion of each clamping arm is provided with an arc claw matched with the pipeline, and the upper end of each clamping arm is driven by a clamping hydraulic cylinder. The arc fixing blocks, the hinge shafts and the clamping hydraulic cylinders of each clamping mechanism are fixedly connected with the corresponding two side plates, and each arc fixing block is arranged above the arc claw of the corresponding clamping arm. The positioning and clamping device is reliable in work performance and good in adaptability.
Description
technical field [0001] The invention relates to a fully hydraulically driven numerical control friction stitch welding machine, in particular to a positioning and clamping device for a fully hydraulically driven numerically controlled friction stitch welding machine.
