Fuel tank end cover closing machine

Abstract

The invention relates to the technical field of fuel tanks, and discloses a fuel tank end cover closing machine which comprises a fixed bottom plate. Supporting frames are installed on the two sides of the upper end of the fixed bottom plate, a top plate is installed at the top ends of the supporting frames, a motor plate is installed in the middle of the lower end of the top plate, a fixed plateis installed at the lower end of the motor plate and a power motor is installed at the lower end of the fixed plate. An output shaft at the front end of the power motor is connected with a driving pulley, the outer side of the driving pulley is connected with a driven pulley through a belt, a connecting rod is hinged to the non-circle-center position of the driven pulley, a movable column is hinged to the other end of the connecting rod, closing blocks are connected to the other end of the movable column and slidably arranged in a guide cylinder, and a closing cylinder is mounted in the middleof the guide cylinder. According to the fuel tank end cover closing machine, rapid extrusion closing of the top of an oil supplementing pipe is achieved, rotation of a fuel tank is achieved under theaction of a movable plate, the purpose of uniform closing is further ensured, the two closing blocks adopt the same power source, and the device cost is further reduced.

Description

technical field [0001] The invention relates to the technical field of fuel tanks, in particular to a fuel tank end cover closing machine. Background technique [0002] Fuel tanks, i.e. fuel storage devices, place high demands on corrosion resistance. In double working pressure, it should be sealed when the gauge pressure is at least 0.03MPa. The resulting overpressure must be relieved itself via an orifice or safety valve. Fuel should not flow out of the liquid filling seal cap or pressure equalization device when driving on a curve, on an inclined road or on an impact. The fuel tank must be installed away from the engine to avoid igniting the fuel in the event of a traffic accident.

Problems solved by technology

[0003] In the process of processing the aluminum alloy square fuel tank of automobiles, the closing of the end cap of the fuel tank in the existing domestic technology is generally molded; the problems of this method are: 1. The investment in manufacturing the mold is relatively large, and the existing Mold molding, if the customer's design is changed, the mold must be changed, the cycle is longer, debugging is difficult, and the investment cost is higher; 2. Using the mold molding process, the mold is easy to wear and needs to be repaired. Because the mold used in this process is large, The maintenance cost is high; 3. The mold has a certain hardness after the mold is made, because the hardness of each batch of materials used to make the fuel tank is inconsistent, resulting in inconsistent dimensions of the processed fuel tank end cap product, resulting in the fuel tank end cap in the next process. Difficult to assemble with the box

[0004] Chinese patent (notification number: CN104325039B) discloses a fuel tank end cap closing machine, including an organic base, a workbench arranged on the machine base, and a transverse feed device and a longitudinal feeder are arranged on the machine base above the workbench. The feeding device, the infeed device includes an infeed screw driven by an infeed motor, and the infeed screw is connected with the infeed screw nut seat arranged on the infeed guide rail, The main shaft seat of the closing machine head is installed on the said transverse feed screw nut seat, and the main shaft of the closing machine head is installed on the said main shaft seat of the closing machine head, although this device can realize the effective closing of the end cover opening to a certain extent, However, in actual operation, fast and uniform closing cannot be performed, so further improvement is still needed
