Problems solved by technology
When the cooling nozzle is installed, it is fixed on the positioning light hole of the engine block through the positioning pin to ensure the accuracy of its installation position. However, most of the positioning pins are located close to the nozzle spray body, and it is easy to spray oil due to the small cumulative tolerance of the positioning size. The beam cannot hit the part that needs to be cooled; and the general positioning pins are fixed on the nozzle spray body by metal, which is completed by machining, the processing is complicated, the production cost is high, and the accuracy is not easy to guarantee

The invention relates to a piston cooling nozzle, and belongs to the technical field of piston cooling nozzles for diesel engines. The piston cooling nozzle comprises a nozzle spray body, a spray pipeand an annular arm, wherein the annular arm sleeves on the outer side of the nozzle spray body and is integrally formed by adopting plastic injection molding; a positioning pin is arranged under theend part, far away from the nozzle spray body, of the annular arm; and the spray pipe penetrates through the annular arm so as to be connected with the side surface of the nozzle spray body. Accordingto the piston cooling nozzle provided by the invention, the annular arm is integrally formed by adopting injection molding, so that the component quantity of non-functional parts of the nozzle is reduced, the processing difficulty is reduced, the production cost is reduced, the positioning can be carried out conveniently and accurately, and the use reliability of the piston cooling nozzle is improved.
Description
technical field [0001] The invention relates to the technical field of piston cooling nozzles for diesel engines, in particular to a piston cooling nozzle. Background technique [0002] In diesel engine pistons, jets of oil are sprayed through cooling nozzles to cool down the piston temperature. When the cooling nozzle is installed, it is fixed on the positioning light hole of the engine block through the positioning pin to ensure the accuracy of its installation position. However, most of the positioning pins are located close to the nozzle spray body, and it is easy to spray oil due to the small cumulative tolerance of the positioning size. The beam cannot hit the part that needs to be cooled; and the general positioning pins are fixed on the nozzle spray body by metal, which is completed by machining, which is complicated to process, high in production cost, and difficult to guarantee accuracy. Contents of the invention [0003] Aiming at the defects and deficiencies i...
