Embodiment
[0049] Such as Figure 1-Figure 6 As shown, a planar parallel mechanism device and control method driven by a double five-bar mechanism, its hardware equipment includes a parallel mechanism body part, a detection part and a control part;
[0050] The body part of the parallel mechanism includes two planar five-bar mechanisms, a moving platform 12 and a static platform 1, and the static platform 1 is a square profile seat, which is used as a test bench to support the whole device. The moving platform 12 is divided into two parts, the lower part is a parallelogram platform, wherein two bearing holes are arranged at the upper and lower diagonal positions, and is connected with each driving branch chain through a rotating shaft, and the upper part is an equilateral triangle platform.
[0051]The two planar five-bar mechanisms have the same structure, both including two rigid driven rod body units, and the two rigid driven rod body units have the same structure, both including a ri...
