Description

Technical Field

[0002] The fuel manifold assembly is an essential and important part of the fuel delivery system. Since the fuel manifold assembly plays a vital role, the production quality of the fuel manifold assembly is very important.

[0003] The Chinese patent application number: CN201721729078.2 provides a sealing detection device for a fuel pipe. This solution is used for a sealing detection device for a fuel pipe, which matches the structural characteristics of the fuel pipe and effectively seals the opening of the fuel branch pipe. The operation of the push pin is only to make it cooperate with the lifting plug to seal the opening of the fuel branch pipe. The operation is simple and the controllability is strong. It meets the needs of sealing detection for fuel pipes.

[0004] The existing online test of fuel manifold components has certain drawbacks when in use. First, the fuel manifold components need to be positioned when performing strength tests on the online test of the fuel manifold components. The commonly used online test positioning components of the fuel manifold components are less convenient for positioning the fuel manifold components, and certain vibration forces are generated during the detection process, resulting in reduced stability in the positioning of the pipeline components. For this reason, we propose an online testing machine for fuel manifold components. Utility Model Content

[0045] By installing the driving member 103, the driving member 103 is composed of a motor and a screw. When the driving member 103 is started, it can interact with the external sleeve guide block 104 through a threaded action, so that the guide block 104 can drive the support frame 201 to adjust the position. The transmission member 105 is composed of a motor, a screw with opposite threads at the outer end, and a sleeve block. When the driving member 103 is started, it can drive a pair of moving frames 106 at the upper end to move, so that the positioning mechanism 3 at the inner end of the moving frame 106 can be adjusted and positioned according to the fuel main pipe assemblies of different lengths.

At this time, the fuel main pipe assembly to be tested is placed on the inner end of the positioning groove 301.
