Problems solved by technology

Although the structure of the fixed positioning pin is simple, it cannot be stretched, so that when installing and disassembling the workpiece, the workpiece needs to be lifted to a certain height, which increases the workload during processing and reduces work efficiency.
However, the traditional locating pins that are telescopically realized by the crank slider mechanism can realize the free telescoping of the locating pins, but the structure is complex, there are too many parts, it is inconvenient to process, and it is not easy to assemble and shape, and the manufacturing, processing and assembly costs are high.

Abstract

The invention discloses a hydraulic driving telescopic type positioning pin, which comprises a pin body, a hydraulic cylinder, a telescopic rod, a flat plate cam, a push rod, a roller and a clamp body, wherein the hydraulic cylinder, the push rod and the telescopic rod are arranged on the clamp body, the hydraulic cylinder is connected with one end of the push rod, the flat plate cam is fixedly arranged on the push rod, a spring is sheathed outside the telescopic rod, the roller matched with the flat plate cam is arranged on the telescopic rod and is positioned at the lower end of the spring, and the pin body is arranged on the telescopic rod and is positioned at the upper end of the spring. The hydraulic driving telescopic type positioning pin is used for processing and positioning a box body type workpiece with two holes at one side, the structure is simple, the operation is simple and convenient, and the positioning is reliable.

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. Contents of the invention [0003] Aiming ...
