Problems solved by technology
However, manual press-fitting cannot guarantee the balance of the press-fitting force, the smoothness of the press-fitting process, the assembly quality cannot be effectively guaranteed, and the assembly efficiency is low, which seriously affects the mass production of fuel manifolds
In particular, the structure of the common fuel pipe connection bolt tightening machine on the market is also relatively complicated.

The invention relates to an assembling tool for a fuel manifold assembly of a direct injection engine in a cylinder. Two avoiding notches are formed in the left side and the right side of the front face of a bottom plate body of a bottom plate respectively. Two cushion blocks are detachably connected to the lower surfaces of two connecting seats respectively and are provided with through holes, and the two connecting seats are provided with matched through holes. A top plate is located above the bottom plate. The upper ends of two pressing rods are connected with the two ends of the top plate respectively, and the lower ends of the two pressing rods penetrate longitudinal through holes in a bottom plate body of the bottom plate respectively to stretch out downwards. The upper ends of two guide rods penetrate longitudinal guide through holes in the top plate respectively to stretch out upwards, and the lower ends of the two guide rods are connected with the bottom plate body of the bottom plate. The upper end of a locating block is connected with the bottom plate body of the bottom plate, and the lower end of the locating block is suspended. A bearing sleeve is connected to the center position of the upper surface of the top plate and is provided with a rotatable bearing. A screw rod penetrates a screw sleeve from top to bottom, and the lower end of the screw rod is connected with the bearing on the bearing sleeve. An upper supporting body of a supporting seat is connected with the bearing sleeve, and a lower supporting body of the supporting seat is connected with the upper surface of the bottom plate body of the bottom plate.
Description
technical field [0001] The invention relates to engine tooling, in particular to an assembly tooling for fuel oil manifold assembly of an in-cylinder direct injection engine. Background technique [0002] In order to ensure more complete fuel combustion, a large number of automobiles have adopted in-cylinder direct injection engines. Usually, in the process of assembling the fuel manifold assembly of an in-cylinder direct injection engine, it is necessary to first install the fuel injector of the fuel manifold assembly to the fuel injection hole of the cylinder head and press it in place, and then tighten the connecting bolts of the fuel manifold; or use The common fuel pipe connecting bolt tightening machine on the market automatically presses the fuel pipe and tightens the fuel pipe connecting bolts at the same time. Due to the special assembly position of the fuel main pipe assembly and the narrow space, and the large volume of the fuel main pipe bolt tightening machine,...
