Description

Electric pile and assembling method Technical Field The application relates to the field of batteries, in particular to a galvanic pile and an assembly method. Background A stack is a core component of a fuel cell system, which is a device that converts hydrogen and oxygen into electric energy through chemical reactions. The stack generally includes first and second end plates disposed opposite each other with a plurality of unit cells disposed therebetween. A screw rod is arranged between the first end plate and the second end plate, one end of the screw rod is fixedly provided with a limiting plate, and the screw rod is matched with a nut. The first end plate and the second end plate are provided with through holes for the screw rod to penetrate. The stack is assembled by placing the first end plate on the table of the press. The cells are then placed in sequence on the first end plate. And then the second end plate is covered on the single battery, and the press is started. The press presses the second end plate, which presses the unit cells toward the first end plate, thereby tightly pressing each unit cell against each other. The second end plate is extruded by the holding press, the screw rod penetrates through the through hole, the nut is screwed into the screw rod, the limiting plate is abutted against one side, far away from the second end plate, of the first end plate, and the nut is abutted against one side, far away from the first end plate, of the second end plate. The press is then closed and the first and second end plates are held tight against each individual motor by the nut, screw and stop plate engagement. With respect to the related art described above, the inventors consider that each stack generally has a plurality of sets of nuts, screws, and limiting plates for locking the first end plate and the second end plate, thereby facilitating the compression of the unit cells by the first end plate and the second end plate. However, when assembling the stack, a plurality of nuts need to be screwed into the screws, thereby reducing the assembling speed of the stack. Disclosure of Invention In order to improve the assembly speed of a galvanic pile, the application provides the galvanic pile and an assembly method. The application provides a galvanic pile and an assembly method, which adopts the following technical scheme: The utility model provides a galvanic pile, includes relative first end plate and the second end plate that sets up, be provided with a plurality of battery cells between first end plate and the second end plate, the week side fixed mounting of first end plate has a plurality of first installation piece, the week side fixed mounting of second end plate has a plurality of second installation piece, first installation piece is provided with the connecting rod, the one end of connecting rod articulates there is the screw rod, the one end fixed mounting that the screw rod was kept away from to the connecting rod has the limiting plate, the screw rod thread cover is equipped with the nut, first through-hole that supplies the connecting rod damping to wear to establish is seted up to first installation piece, the limiting plate supports to paste in one side that the second installation piece was kept away from to first installation piece, the second through-hole that supplies the screw rod to wear to establish is seted up to the second installation piece, one side that the second end plate was kept away from to the second installation piece has been seted up and has been dodged the mouth, dodged mouth and second through-hole intercommunication, dodged the mouth is used for supplying the screw rod to rotate to get into the second through-hole. Through adopting above-mentioned technical scheme, in the in-process of placing single battery in proper order in first end plate, pass first through-hole with connecting rod and screw rod to screw in screw rod part with the nut. And then when the single batteries are stacked, and the second end plate is pressed on the single batteries, the screw rod is rotated, and the screw rod enters the second through hole from the avoiding opening, so that the nut moves to one side of the second end plate away from the first end plate. And when the nut moves to one side of the second end plate away from the first end plate, the nut is rotated again to enable the nut to be tightly abutted against the second mounting block. The nut is screwed into the screw rod when the single batteries are stacked, so that the assembly speed of the electric pile is improved. Optionally, the hinge groove has been seted up to the one end that the connecting rod is close to the screw rod, the one end fixed mounting of screw rod has the hinge piece, the inside axostylus axostyle that is provided with of hinge groove, the tip fixed mounting of axostylus axostyle is in the inside wall of hinge groove, the axostylus axostyle rotates and runs through the hinge piece. Through adop
