Automatic pressing and welding equipment for automobile low-pressure fuel distributing pipe

Abstract

The invention discloses automatic pressing and welding equipment for an automobile low-pressure fuel distributing pipe. The automatic pressing and welding equipment comprises an automatic pressing and welding equipment body. The automatic pressing and welding equipment body is composed of a clamp, a rotation workbench, a measuring station, a pressing mechanism, a laser welding station and a vibration feeding mechanism. The clamp, the measuring station, the pressing mechanism and the laser welding station are arranged on the upper side of the rotation workbench. An electric control cabinet is arranged on the right side of the automatic pressing and welding equipment body, and a laser main machine is arranged on the right side of the electric control cabinet and connected with a laser head. A water cooling machine is arranged on the right side of the laser main machine. The automatic pressing and welding equipment is high in automation degree, labor force is saved, and the labor cost is reduced; the production efficiency is improved, and the occupied area of the equipment is reduced; the qualification rate of the product quality is improved, and the appearance is more attractive; and data tracing in the product production process is achieved.

Description

technical field [0001] The invention relates to a welding device, in particular to an automatic press-fit welding device for an automobile low-pressure fuel distribution pipe. Background technique [0002] Since the 1960s, with the increasing number of automobiles, the continuous rise of automobile exhaust emissions and fuel consumption has troubled people, forcing people to find a new technology device that can purify automobile exhaust and save fuel. The invention and application of the decades-old carburetor and gasoline injection technology have enabled people to realize this ideal; as early as 1967, the German Bosch company successfully developed the D-type electronically controlled gasoline injection device. On Volkswagen cars; this device uses the pressure inside the intake pipe as a parameter, but compared with the carburetor, it still has the disadvantages of complex structure, high cost, and instability; in response to these shortcomings, Bosch has developed A so-...

[0002] Since the 1960s, with the increasing number of automobiles, the continuous rise of automobile exhaust emissions and fuel consumption has troubled people, forcing people to find a new technology device that can purify automobile exhaust and save fuel. The invention and application of the decades-old carburetor and gasoline injection technology have enabled people to realize this ideal; as early as 1967, the German Bosch company successfully developed the D-type electronically controlled gasoline injection device. On Volkswagen cars; this device uses the pressure inside the intake pipe as a parameter, but compared with the carburetor, it still has the disadvantages of complex structure, high cost, and instability; in response to these shortcomings, Bosch has developed A so-called L-type electronically controlled gasoline injection device, which uses the air flow in the intake pipe as a parameter, can directly determine the intake air volume according to the relationship between the intake air flow and the engine speed, and inject corresponding gasoline accordingly; this device Due to its reasonable design and reliable operation, it is widely used by automobile manufacturing companies in Europe and Japan, and has established the Zou type of electronically controlled fuel injection devices today; since 1979, GM, Ford in the United States, Toyota, Mitsubishi, and Nissan in Japan, etc. Automobile companies have introduced their own electronically controlled gasoline injection devices, especially the promotion of multi-valve engines, which has rapidly popularized and applied electronically controlled injection technology; More than 95% have installed fuel injection devices; from January 1, 1999, only cars with electronically controlled gasoline injection devices can be approved to be sold in the Beijing market

[0003] The fuel distribution pipe in the automobile engine is a mechanical device, also known as the fuel rail or fuel rail, which is an integral part of the air / fuel subsystem in the electronically controlled fuel injection system, installed on the intake manifold, located in the injector At present, when welding the low-pressure fuel distribution pipe, manual welding is generally used, the production efficiency is low, and the equipment occupies a large area; errors are prone to occur due to manual welding, and the data cannot be traced
