The invention discloses a fuel tank chuck dismounting tool, comprising: a grooved wheel structure and a plurality of claws, the grooved wheel structure includes overlapping fixed disks and a rotating disk, the rotating disk can rotate around the central axis of the fixed disk, and the fixed disk There are a plurality of fixed disk guide grooves extending radially from the circumference of the fixed disk to the central axis of the fixed disk. The rotating disk is provided with a plurality of rotating disk guide grooves intersecting with the fixed disk guide grooves. The claws are arranged in the grooves. Below the wheel structure, and the end of each claw extends below the sheave structure. The front end of the claw is provided with a guide post, which is inserted into the guide groove of the rotating disk and the guide groove of the fixed disk. When the rotating disk rotates around the central axis of the fixed disk, The guide groove of the rotating disk pushes the guide column to move along the direction of the guide groove of the fixed disk. The invention drives the guide column to move along the guide groove of the fixed disk through the guide groove of the rotating disk, so as to open or close all the claws at the same time, so as to realize the rapid disassembly and assembly of the oil tank chuck.
Description
technical field [0001] The invention relates to the technical field related to automobiles, in particular to a fuel tank chuck disassembly tool. Background technique [0002] In order to meet the emission requirements of existing automobiles, the fuel tank and oil pump of the vehicle must be sealed with a chuck type to reduce the leakage of gasoline vapor in the fuel tank. In vehicle testing and vehicle maintenance, it is often necessary to disassemble and assemble the fuel pump, and it is necessary to quickly and easily disassemble and assemble the fuel tank chuck used to fix the fuel pump on the fuel tank. [0003] Such as figure 1 Shown is a schematic diagram of the installation of the fuel tank chuck 7 . An oil pump 9 is arranged in the oil tank 8 , and the oil pump 9 is surrounded by a collar 10 . [0004] The disassembly and assembly of the fuel tank chuck in the prior art requires the use of a hammer and a chisel. Due to the high clamping force of the fuel tank chu...
