Description

Welding and pressing tool for nozzle shell

Technical Field

The utility model belongs to the technical field of nozzle shell welding, a nozzle shell compresses tightly frock with welding is related to.

Background

It is known in the art that it is particularly important to control the amount of deformation of a fuel rail welded to a nozzle body during the welding process. The existing technology for controlling the deformation amount compresses the end surface of the nozzle shell through a pressure plate to control the deformation amount, and referring to fig. 1, the nozzle shell is compressed through the linear contact of the front end of the pressure plate and the upper end of the nozzle shell. However, in the actual vacuum brazing process, the fuel manifold enters the furnace along with the tool, and after the welding is completed, the manifold is separated from the tool to generate serious deformation, so that the quality of the product is influenced.

Further, the pressing plate is a rectangular pressing plate.

Furthermore, one end of the rectangular pressing plate is provided with a first mounting hole, the other end of the rectangular pressing plate is provided with a second mounting hole, and the first mounting hole and the second mounting hole are respectively provided with threads.

Further, the first fastener adopts a single-end stud, and the single-end stud is matched with the second mounting hole.

Further, the second fastener adopts stud, stud's upper end and first mounting hole looks adaptation, stud's lower extreme and the third mounting hole looks adaptation that the frock bottom plate upper surface set up.

Further, stud's upper end is equipped with the screw thread, and the lower extreme is equipped with down the screw thread, go up the screw thread and the screw thread looks adaptation of first mounting hole, the screw thread looks adaptation of lower screw thread and third mounting hole.

Compared with the prior art, the utility model provides a technical scheme includes following beneficial effect: the line contact between the pressing plate and the upper end face of the nozzle shell is changed into point contact, so that the nozzle shell is pressed reliably and effectively, the welding deformation of the fuel main pipe can be strictly controlled after the fuel main pipe is welded and separated from a tool, and the product quality is ensured.
