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.

Embodiment Construction

[0014] A telescoping pin rapid positioning device according to the present invention, see figure 1 : The device includes a hydraulic motor 1, a shaft 5, a cam 8, a push rod 9, a clamp body 4, a pin body 6 and a spring 7; the hydraulic motor 1 is connected to the shaft 5 through a coupling 2. The shaft 5 is arranged on the clamp body 4 through the bearing 3 . The cam 8 is arranged on the shaft 5 via a key 10 . The number of cams can be set as required, and in this embodiment, two cams are arranged on the shaft 5 . The lower end of the push rod 9 is adapted to the shape of the cam 8, and a groove 81 for limiting the movement of the push rod 9 is provided at the central position of the raised part of the cam 8. The groove 81 will stop the push rod 9 at that position. It will only move again under the action of external force. The upper end of the push rod 9 stretches out of the clamp body 4, and the pin body 6 is arranged on the top of the push rod 9; the spring 7 is sleeved o...

Abstract

The invention discloses a telescopic pin fast positioning device, which comprises a hydraulic motor, a shaft, a cam, a push rod, a clamp body, a pin body and a spring, wherein the hydraulic motor is connected with the shaft arranged on the clamp body, the cam is arranged on the shaft, the lower end of the push rod is matched with the cam, the upper end of the push rod extends out of the clamp body, the pin body is arranged at the top end of the push rod, and the spring is sheathed on the push rod and is positioned between the clamp body and the lower end of the push rod. The fast positioning device disclosed by the invention has the advantages that the structure is simple, the operation is convenient, and the labor is saved.

Description

technical field [0001] The invention relates to a positioning device, in particular to a quick positioning device for telescopic pins. Background technique [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 [00...
