Motorcycle fuel tank airtightness detection automation equipment

Abstract

The invention discloses motorcycle fuel tank airtightness detection automation equipment. The equipment comprises a rack, the rack is provided with a positioning tool used for placing a fuel tank workpiece, a first linear driving device is installed above the rack, the driving end of the first linear driving device is provided with a rotary clamping cylinder, an air inlet ring is fixedly connected to the lower end of a cylinder body of the rotary clamping cylinder, a telescopic rod of the rotary clamping cylinder penetrates through an inner hole to be fixedly connected with a pulling and pressing column, and first protruding blocks are arranged on the two sides of the lower end of the pulling and pressing column; and the lower end of the air inlet ring is fixedly connected with an oil port plugging head, and the oil port plugging head is located above the positioning tool and matched with the position of an oil filling port of the fuel tank workpiece. Deformation caused by extrusion of a fuel tank is avoided, space layout is reasonably utilized, the takt time of the whole production line is guaranteed, the structure is simple and compact, the detection cost is low, and convenience and practicability are achieved.

Description

Technical field: [0001] The invention relates to the technical field of air tightness detection, in particular to an automatic equipment for air tightness detection of a motorcycle fuel tank. Background technique: [0002] The shell of the motorcycle fuel tank is formed by stamping, and then welded with other surrounding structures and oil filling ports. Welding defects cannot be ruled out, so leak testing is required. At present, most of the automatic equipment for air tightness detection of motorcycle fuel tanks in China adopts water inspection, that is, manually inflates the fuel tank into water to observe whether there is bubbles, and then takes it out and blows it dry. Plugging is random and inefficient. The tested product needs to be dried before it can be transferred to the next process, which increases the production cost. At the same time, the environment is harsh. After the water test, the fuel tank is easy to rust, which affects the product quality. Human operati...

Problems solved by technology

At present, most of the automatic equipment for air tightness detection of motorcycle fuel tanks in China adopts water inspection, that is, manually inflate the fuel tank into water to see if there is any bubbles, and then take it out and dry it. Plugging is random and inefficient. The tested product needs to be dried before it can be transferred to the next process, which increases the production cost. At the same time, the environment is harsh. After the water test, the fuel tank is easy to rust, which affects the product quality. Human operation is not conducive to mass production, and it is difficult to realize automation and intelligence; so some companies use helium detection, but this detection method has high equipment costs, helium is a consumable, and the detection cost is high, which makes many manufacturers unacceptable ; Therefore, it is necessary to develop a convenient and practical motorcycle fuel tank air tightness detection device
