Description

technical field

[0001] The invention relates to a positioning pin, in particular to a hydraulic telescopic positioning pin. technical background

[0002] The traditional positioning device with two pins on one side has both fixed positioning pins and positioning pins that are telescopically realized by the slider crank mechanism. Although the structure of the fixed locating pin is simple, it cannot be telescopic, so that when the workpiece is installed and disassembled, the workpiece needs to be lifted to a certain height, which increases the workload during processing and reduces work efficiency. However, the traditional positioning pin realized by the crank-slider mechanism can realize the free expansion and contraction of the positioning pin, but the structure is complicated, there are too many parts, it is not convenient to process, it is not easy to assemble and shape, and the manufacturing process and assembly cost is high.
