[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4 , a positioning device for a workpiece transportation trolley, comprising a frame body. The frame body includes a pair of first connecting benches 1 and second connecting benches 2 arranged in parallel to each other. A first guiding strip 7 is installed on the first connecting bench 1, and a second guiding strip 8 is installed on the second connecting bench 2. Three pairs of floor supporting members 9 are symmetrically arranged between the first connecting bench 1 and the second connecting bench 2; A pair of parallel first connecting cross beams 3 and second connecting cross beams 4 are connected between one ends of the first connecting bench 1 and the second connecting bench 2. A first cylinder lifting assembly 5 is connected at the central position of the first connecting cross beam 3, and a pair of second cylinder lifting assemblies 6 are symmetrically installed on the inner side surfaces of the first connecting bench 1 and the second connecting bench 2.

[0025] In the above embodiment, the first cylinder lifting assembly 5 includes a first mounting block 501 installed at the center position of the first connecting cross beam 3. A through hole is drilled in the first mounting block 501 to install a first cylinder 502 with a floating joint, and a pair of first linear bearings 503 symmetrically installed on both sides of the first cylinder 502. A first guide shaft 504 is inserted and installed in each first linear bearing 503. A first push plate 505 is installed on the piston head of the first cylinder 502. A first support plate 506 is installed at the lower ends of the two first guide shafts 504 and the first cylinder 502. At both ends of the first push plate 505, a diamond pin 507 and a round pin 508 are installed through holes for assembly and positioning with the positioning holes on the trolley. A support 509 is installed on the outer side surface of the first push plate 505. A pair of shock-absorbing members 510 are symmetrically arranged between the support 509 facing the outer side surface of the first push plate 505. The shock-absorbing members 510 are made of polyurethane material.

[0026] In the above embodiment, the second cylinder lifting assembly 6 includes a second mounting block 601 installed on the side surface of the first connecting bracket 1 or the second connecting bracket 2. A through hole is drilled in the second mounting block 601 to install a second cylinder 602 with a floating joint, and a pair of second linear bearings 603 symmetrically installed on both sides of the second cylinder 602.
