Nozzle component shooting test and calibration machine

Abstract

The invention discloses a target test and calibration special machine for a nozzle assembly and belongs to the technical field of test and calibration equipment for engine parts. The target test and calibration special machine comprises a rack, wherein a nozzle test device is arranged on the rack, the nozzle test device comprises a device body, a positioning surface is arranged on the device body, and a positioning pin and an auxiliary positioning pin are arranged on the positioning surface; a first oil passage communicating with an oil supply system is arranged in the device body, and the positioning pin is provided with a second oil passage communicating with the first oil passage; a pressing head driven by a linear driving device is mounted on the rack in a sliding manner and positioned above the nozzle test device; and a test plate is arranged on the rack and positioned below the nozzle test device, a test hole is formed in the test plate, and an oil cup is arranged below the test hole. The target test and calibration special machine simplifies a test process, is great in universality, can timely adjust the size of a nozzle by a tool when the nozzle assembly is in a pressed state, facilitates a calibration procedure and shortens calibration and test time.

Description

technical field [0001] The invention belongs to the technical field of engine component testing and calibration equipment, and in particular relates to a special machine for testing and calibration of nozzle components. Background technique [0002] Such as figure 1 and figure 2 Commonly shown, an engine nozzle assembly includes a nozzle body 100 and a nozzle 200, the upper and lower surfaces of the nozzle body 100 are flat, and the nozzle body 100 is provided with a positioning hole 300 penetrating from the upper surface to the lower surface and setting An auxiliary positioning hole 400 on one side of the positioning hole 300 . During the manufacturing process of the nozzle assembly, the nozzle body 100 and the nozzle 200 are usually welded together, but the size of the nozzle assembly is easily out of tolerance after welding. Therefore, after welding, it is necessary to perform a target shooting efficiency test. If the target shooting efficiency is lower than If the sp...
