The acid extraction tube 1 is used to extend from the acid injection hole on the top surface of a lead-acid battery into the interior to extract acid, and the end face of the acid extraction tube 1 extending into the interior of the lead-acid battery is sealed, and the side surface is provided with an acid absorption side hole 11.

[0030] The precise positioning acid extraction tube punching device of the present application comprises a base 2, one side of the upper surface of the base 2 is provided with a placement area for placing the acid extraction tube 1 to be punched, and the base 2 is also provided with a positioning mechanism 3 for positioning the acid extraction tube 1.

[0031] The positioning mechanism 3 includes a positioning groove 31 provided in the placement area for placing the acid extraction tube 1 to be punched, and a positioning block 32 provided at one end of the positioning groove 31 for abutting against one end of the acid extraction tube 1 to be punched. The positioning groove 31 is horizontally arranged, and has a V-shaped cross section. On the one hand, it can be adapted to the acid extraction tubes 1 of different sizes and thicknesses. On the other hand, after the acid extraction tube 1 is horizontally placed in the positioning groove 31, the bottom surface is suspended to facilitate punching, and at the same time, a space is provided for accommodating the debris dropped during the punching.

[0032] The positioning block 32 is L-shaped as a whole, and includes a horizontal portion 33 and a vertical portion 34. The horizontal portion 33 is used to be fixed to the base 2, and the vertical portion 34 is used to support one end of the acid extraction pipe 1 to be punched. The vertical portion 34 is provided with a positioning column 35 that extends into the acid extraction pipe 1 to be punched when in use.

[0033] In a preferred embodiment, the horizontal portion 33 is provided with a waist-shaped hole 36 axially parallel to the positioning groove 31, and the positioning block 32 is fixed by a bolt 37 passing through the waist-shaped hole 36 and fixed to the base 2. First, the positioning block 32 and the base 2 are designed to be a detachable structure, and positioning columns 35 of different heights and thicknesses can be used as needed to adapt to acid extraction tubes 1 of different specifications. Secondly, through the setting of the waist-shaped hole 36, the distance between the vertical portion 34 and the positioning groove 31 can be adjusted, so that it can be suitable for acid extraction tubes 1 of different lengths, or holes can be punched at different heights of the acid extraction tube 1.

[0034] The precise positioning acid extraction pipe drilling device of the present application further comprises a lifting frame 4, which is escalably arranged on the base 2 through a mounting bracket 5. The lifting frame 4 is provided with a drill bit 41, which is arranged above the placement area on the base 2 for placing the acid extraction pipe 1, and the drill bit 41 is used to drill the acid extraction side hole 11 in the acid extraction pipe 1.
