Abstract

The invention relates to a positioning tool for welding of a high-pressure oil track support. A high-pressure oil track comprises a main pipe and an upright column support which is arranged in the middle of the main pipe and penetrates through the main pipe; oil atomizer seat holes are respectively formed in two ends of the main pipe; and an upright column through hole is formed in the upright column support. The positioning tool comprises a working table and a main pipe positioning table, wherein the main pipe positioning table is arranged on the working table; a main pipe positioning groove for placing the main pipe is formed in the main pipe positioning table; seat hole positioning pins which are respectively inserted in the oil atomizer seat holes in a matched manner and an upright column positioning pin a which is inserted in a lower opening of the upright column through hole in a matched manner are arranged in the main pipe positioning groove; a support upper positioning assembly capable of moving vertically is further mounted on the working table; and during mounting, the support upper positioning assembly moves downwards, is propped against the high-pressure oil track, and is fixedly placed on the high-pressure oil track in the main pipe positioning groove. Compared with the prior art, the positioning tool has the advantages of good positioning stability, capability of effectively avoiding welding deformation, simplicity in repair and change and the like.

Description

technical field [0001] The invention relates to a positioning tool, in particular to a positioning tool for welding a high-pressure oil rail bracket. Background technique [0002] At present, the spot welding positioning work for the high-pressure fuel rail is usually divided into three parts: the injector seat positioning fixture at both ends, and the fuel rail bracket positioning fixture, and then these three parts are spliced ​​and combined to position the high-pressure fuel rail. The accuracy and efficiency of such a positioning method are affected by many factors, the operation is cumbersome, it is not suitable for mass production, the accuracy is difficult to guarantee, and the clamping is inconvenient. [0003] In addition, because the two sides of the high-pressure fuel rail are not completely symmetrical, the two sides of the high-pressure fuel rail are also slightly different during spot welding. Before spot welding, the high-pressure oil rail is basically symmetr...
