Embodiment Construction

[0026] The working principle of the planar parallel mechanism, which is the core part of this design, will be introduced in detail below in conjunction with the accompanying drawings.

[0027] As shown in Figure 1, the slider drive parallel mechanism consists of fixed length rods 8, 10, output platform 9, active slider 2, active slider 5, and sliding guide rail 1 to form a planar parallel closed-chain structure. Due to the frame structure, the entire structure is very light in weight.

[0028] Fixed-length rods 8,10, slide blocks 2,5 and output platform 9 hinged therewith, plus a plane parallel mechanism formed by guide rail 1, have good rigidity. One end of the telescopic rod 4 is fixed to the follower slider 3 , and the other end is fixed to the output platform 9 to limit the swinging freedom of the output platform 9 . When the sliders 2 and 5 change positions, the hinge points of the rods 8 and 10 also change accordingly, and the positions and postures of the rods 8 and 10...
