The invention discloses a device for disassembling a pump cover of an electric fuel pump of an automobile, which is suitable for disassembling pump covers of various sizes. The device comprises a base body, wherein a driving gear is mounted on the base body; at least two driven gears meshed with the driving gear are distributed uniformly in the circumferential direction of the driving gear and mounted on the base body; each driven gear is connected with a grabbing rod; each grabbing rod comprises a connecting part connected with the corresponding driven gear and a pump cover grabbing part positioned on the outer side of the base body and connected with the connecting part; and the driving gear drives each pump cover grabbing part to move synchronously through each driven gear, so that the distance between each pump cover grabbing part and the axial line of the driving gear still maintains the same. The pump cover grabbing part of each grabbing rod is driven by each driven gear to gradually get close to the driving gear and gradually depart from the driving gear, so that the grabbing rods can form pump disassembling tool of different sizes, and the device is suitable for disassembling the pump covers of different sizes. Adjustment is performed by the gears, so the adjustment precision is high.
Description
technical field [0001] The invention relates to a dismantling device, in particular to a device for dismantling a pump cover of an electric fuel pump of an automobile. Background technique [0002] In the prior art, the pump cover of the automobile electric fuel pump has a special removal tool when it is disassembled. The removal tool generally has a plurality of grab bars, and the pump cover can be separated from the main body of the electric fuel pump through the removal tool. However, the existing disassembly tools can only be used for pump covers of one size, and different sizes of disassembly tools need to be used for disassembly of pump covers of different sizes. And the kind of the pump cover removal tool that most auto repair shops are equipped with is very limited, and this just brings inconvenience to the repair of automobile. Contents of the invention [0003] The technical problem solved by the invention is to provide a device for removing the pump cover of th...
