Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

[0028] Example 1

[0029] See also Figures 1 to 3 As shown, the utility model is a terminal polishing device for a lead-acid battery, comprising a bracket 1 having four support columns, the upper ends of the four support columns being connected to a top plate 101, and the top plate 101 being connected to two telescopic devices 2, which can be a cylinder or an electric push rod.

[0030] like Figure 3 and 4 As shown, the telescopic ends of the two telescopic devices 2 are fixedly connected to a lifting plate 3, the lower surface of the lifting plate 3 is fixedly connected to a motor 301, the upper surface of the lifting plate 3 is rotatably connected to a driving wheel 302 that is transmission-connected to the motor 301, and is rotatably connected to two rotating shafts 4.

[0031] The upper end of the rotating shaft 4 is fixedly connected to a driven wheel 401, and the lower end is fixedly connected to a grinding head 5. The driving wheel 302 and the two driven wheels 401 are connected by a transmission belt, which can be a synchronous belt, for driving the rotating shaft 4 to rotate and grinding the battery terminals through the grinding head 5.

[0032] The grinding head 5 includes an end face brush 501 and two to four brush strips 502 evenly distributed on the circumference of the end face brush 501. A mounting groove can be provided on the side of the end face brush 501, and the upper end of the brush strip 502 is fixed in the mounting groove.

[0033] During polishing, the lifting plate 3 is driven down by the retraction device 2, so that during the rotation of the grinding head 5, the end face of the battery terminal is ground and polished by the end face brush 501, and the circumferential surface of the battery terminal is ground and polished by the brush strip 502, thereby achieving simultaneous grinding and polishing of the end face and circumferential surface of the terminal, ensuring the uniformity of the grinding and polishing of the battery terminal, and effectively improving the overall grinding and polishing effect.

[0034] At the same time, it also includes two fixed plates 102 arranged side by side, and one of the fixed plates 102 is connected to the baffle 103, and the other fixed plate 102 is movably interspersed with three guide rods 108, and is fixedly connected to a positioning plate 104 through the guide rods 108.

[0035] Among them, the bracket 1 can have a bottom plate connected to the lower ends of four support columns, and two fixing plates 102 are fixed on the bottom plate, or the bracket 1 straddles the conveyor line, and the two fixing plates 102 are located on both sides of the conveyor line, so as to fix the position of the battery on the conveyor line.

[0036] Moreover, the middle guide rod 108 among the three guide rods 108 is sleeved with a spring 105 and connected with a handle, which is used to push the positioning plate 104 through the spring 105, so that the positioning plate 104 and the baffle 103 clamp and position the battery.

[0037] Among them, as Figure 1 and 2 shown, the positioning plate 104 is in a C-shaped structure, which is convenient for better positioning the position of the battery 6. By pulling the guide rod 108, the positioning plate 104 is driven to move away from the baffle 103, so that the clamped battery 6 is released, which is convenient for taking out, or directly conveyed and moved by the conveyor line.

[0038] In addition, the baffle 103 is fixedly connected with two guide posts 106 and is movably inserted and connected with the fixing plate 102, and the fixing plate 102 is threadedly connected with a screw rod 107. The screw rod 107 is rotatably connected with the baffle 103, which is used to adjust the position of the baffle 103 by rotating the screw rod 107, so as to position different-sized batteries 6, and make the terminals of the battery 6 always located below the grinding head 5.

[0039] Embodiment 2

[0040] As Figure 4 and 5 shown, on the basis of Embodiment 1, the lifting plate 3 is slidably connected with a slider 303, and the slider 303 is rotatably connected with a tension pulley 304. The lifting plate 3 is slidably connected with two sliding seats 402, and the rotating shaft 4 is rotatably connected to the sliding seats 402.

[0041] Specifically, one side of the lifting plate 3 is turned downwards, and a reinforcing rib is welded between the lower surface of the lifting plate 3 and the side surface of the folding part, which is used to ensure the overall structural strength. The sliding seat 402 is slidably connected to the side surface of the folding part, so as to effectively ensure that the heights of the driving wheel 302 and the driven wheel 401 are the same.

[0042] As Figure 6 shown, by adjusting the position of the sliding seat 402, the terminals of different-sized batteries can be polished, and by adjusting the position of the slider 303, the tension pulley 304 is used to tension the transmission belt, and after adjustment, the sliding seat 402 and the slider 303 can be locked.

[0043] Specifically, the slider 303 and the two slides 402 are distributed in an isosceles triangle, and the slider 303 and the two slides 402 are hinged via a connecting rod 403 to achieve synchronous position adjustment between the slider 303 and the slides 402.

[0044] like Figure 6 As shown by the middle arrow, when the distance between the two terminals of the battery 6 is small, the distance between the two slides 402 is adjusted so that the distance between the two grinding heads 5 is adjusted to correspond to the position of the two terminals of the battery 6. In addition, when the slide 402 moves, the connecting rod 403 drives the slider 303 to move, so that the tensioning wheel 304 can always tension the transmission belt.

[0045] At the same time, the lifting plate 3 is rotatably connected to a screw rod 305, and both slides 402 are fixedly connected to a screw nut that cooperates with the screw rod 305. One end of the screw rod 305 is connected to a crank handle, which is used to synchronously adjust the movement of the two slides 402 toward and away from each other by rotating the screw rod 305. If the screw rod 305 has two sections of mutually opposite threads, the movement of the two slides 402 can be synchronously adjusted by rotating, making the overall adjustment more convenient and accurate.
