Abstract

A positioning device used for connection rods and shell parts. The device comprises a positioning sleeve device, a hydraulic device, an in-sleeve transmission device and a guide pin device. One end of the in-sleeve transmission device is connected with the guide pin device, and the other end of the in-sleeve device penetrates through the positioning sleeve device and is connected with the hydraulic device. The in-sleeve transmission device comprises a pulling rod and a pulling nail, a T-type groove is formed in the end, close to the hydraulic device, on the pulling rod, the pulling nail is arranged in the T-type groove, and the pulling nail is connected with the hydraulic device. The other end of the pulling rod is evenly provided with dovetail inclined concave grooves. The guide pin device comprises a plurality of guide pin sets evenly distributed on the positioning plane. Each guide pin set comprises a guide pin and a positioning screw. A dovetail inclined convex groove is formed in one end of the inner side of each guide pin, and the shape, and the size and the position of each dovetail inclined convex groove correspond to those of the corresponding dovetail inclined concave groove. One end of the inner side of each guide pin extends to the axis of the in-sleeve transmission device. A flat bottom thread is arranged at one end of the outer side of each guide pin. The positioning screws are installed on the flat bottom threads. The positioning device has the advantages that a hydraulic expansion core positioning pin can achieve high-precision positioning, the parts can be easily clamped, and the problem that clamping for ensuring high-precision positioning is difficult is solved.

Description

Technical field [0001] The patent of the present invention relates to a positioning device, especially a precise positioning device for connecting rods and shell parts. Background technique [0002] Pin positioning is often used in connecting rods, reducer housings, transmission housings, clutch housings, intermediate housings and other technological equipment that are positioned by holes. Generally there are round pins and diamond pins, but ordinary round pins and diamond pins are Rely on tolerance to ensure positioning accuracy. When the tolerance is relatively small, the positioning accuracy is relatively high, but it will be difficult to clamp the parts at this time. When the tolerance is relatively large, the part clamping operation is easier, but the positioning accuracy will be reduced accordingly. Especially when the size of the positioning holes of some parts is relatively large, ordinary round pins and diamond pins are used for positioning, it will be difficult to cla...
