Assembly technique for supporting plate and supporting rod of fuel oil dispensing pipe and clamp thereof

Abstract

The present invention relates to a support plate and support rod assembling fixture for a fuel oil distributing pipe. The fixture includes a pedestal, an A cushion block, a support rod first pin stop, a first pin, a support rod second pin stop, a B cushion block, a Phi 7 height limit column, an adjustable cushion, a fine adjustable bolt, a poka-yoke ring, a Phi 6.4 height limit column, a guide pillar, a movable pressing board, a linear bearing, a pressing block, an auxiliary hook, an A press head, a press head connecting pole, a B press head and a second pin. The assembling process comprises: respectively putting two first support rods with a diameter of 6.4mm and two second support rods with a diameter of 7mm in the height limit column with an internal bore diameter of Phi6.4 at the two sides and the height limit column with an internal bore diameter of Phi 7 at the middle; putting the support plate on the four support rods, aligning assemble holes on the support plate with the four support rods, starting a press for pressing the support plate and the four support rods in place, pressing the four support rods in place by the A press head and the B press head, and riveting, hoisting the movable pressing board by the auxiliary hook and taking out the product. The present invention has high product quality and high production efficiency.

Description

technical field [0001] The invention relates to an assembly process and fixture for a fuel distribution pipe support plate and a support rod, in particular to an assembly process and a fixture for a fuel distribution pipe support plate and a support rod for an automobile gasoline direct injection engine EA888, belonging to an engine fuel distribution pipe technology field.

[0002] Automotive gasoline direct injection engine EA888 is currently the world's leading gasoline direct injection engine, newly developed by the German Volkswagen Group, equipped with mid-to-high-end cars, the gasoline direct injection fuel rail gets rid of the traditional gasoline engine fuel injection mode, and electronically precisely controls the fuel injection in the cylinder , to maximize the potential of every drop of fuel, to ensure more thorough combustion than other engines in the same period of time, while reducing fuel consumption, it provides more rapid power and environmental protection. Its working pressure is 150Pa, which is the work of ordinary engines The pressure (3.5Pa) is 50 times, and the peak power of 118KW is output under the premise of saving fuel, which is equivalent to the power output by a common engine with a displacement of 2.4L. However, the fuel distribution pipes of this engine are all imported and expensive, and To localize, the assembly of fuel distribution pipe support plate and support rod is the key
