Description

Technical Field

[0001] The utility model relates to the technical field of composite nozzle positioning tooling, and specifically relates to a positioning tooling for composite nozzle processing. Background Technique

[0002] When the fuel pressure in the oil cavity is higher than a set value, the oil valve opens, and the fuel is ejected through the nozzle cap. The oil valve consists of a valve body, a valve seat and a spring. The rear end of the valve seat is connected to the cavity to form an oil cavity. The cavity is provided with an inlet channel leading to the oil cavity. During the processing of the composite nozzle, it is necessary to clamp and position the nozzle.

[0003] The Chinese patent discloses a positioning device for alloy nozzle processing, with the publication number CN218697628U, which includes a bracket; and a positioning component connected to the bracket for positioning the alloy nozzle; the positioning component includes: a telescopic member penetrating the bracket; a sliding frame fixedly connected to one side of the telescopic member; and a placing plate fixedly connected to the sliding frame; a rotating frame is slidably connected inside the sliding frame; the middle of the rotating frame is rotatably connected to the bracket; a positioning head is fixedly connected to the side of the rotating frame away from the sliding frame; the number of the rotating frames is two groups. By setting the fixing component, the device can further fix the alloy nozzle. In this embodiment, by combining the positioning component and the fixing component, the device can position the alloy nozzle, greatly improving the stability of the alloy nozzle and avoiding the movement of the alloy nozzle during the processing.

[0004] However, it still has the following disadvantages: The device uses two positioning heads to clamp the outer surface of the composite nozzle and two fixing plates to clamp the front and rear end faces of the composite nozzle. However, this clamping method has a strong wrapping property and is not convenient for processing the outer surface of the composite nozzle, greatly reducing the processable area of the composite nozzle. For this reason, we propose a positioning tooling for composite nozzle processing to solve this problem. Content of the Utility Model
