[0034] See also Figure 1 and Figure 2As shown, a battery grinder corresponding to a preferred embodiment of the utility model is used to grind a battery 100. The battery grinder comprises: a housing 200, a closed mounting cavity 210 is formed inside, a socket 220 communicating with the mounting cavity 210 is opened on the top of the housing 200; a rotating driving member 300 is fixed in the mounting cavity 210; a grinding wheel 400 is accommodated in the mounting cavity 210 and is correspondingly arranged below the socket 220, and the grinding wheel 400 is transmission-connected with the rotating driving member 300; wherein, the end of the battery 100 can extend from the socket 220 into the mounting cavity 210 and contact the grinding wheel 400.

[0035] The utility model adopts the above structure. When the battery 100 needs to be polished, the operator only needs to insert the battery 100 into the socket 220 and make the welding point at the end of the battery 100 contact with the grinding wheel 400. The rotating drive member 300 can drive the grinding wheel 400 to rotate to polish the welding point. The operator does not need to hold the grinder, which is convenient to operate and has high grinding efficiency. In addition, since the rotating drive member 300 and the grinding wheel 400 are both accommodated in the housing 200, the safety hazard of the operator accidentally touching the rotating drive member 300 and the grinding wheel 400 can be effectively avoided.

[0036] Furthermore, a guide sleeve 500 is fixed in the socket 220, and the inner diameter of the guide sleeve 500 is adapted to the outer diameter of the battery 100. The battery 100 can be inserted to a preset position under the guidance of the guide sleeve 500 to accurately match the grinding wheel 400. Preferably, the guide sleeve 500 is detachably connected to the socket 220, so that the corresponding guide sleeve 500 can be replaced according to the different outer diameters of the battery 100.

[0037] The guide sleeve 500 includes a sleeve body 510, a flange 520 and a fastener (not shown). The sleeve body 510 is inserted into the socket 220, and the sleeve body 510 extends toward the grinding wheel 400 in the vertical direction. There is a non-zero gap between the sleeve body 510 and the grinding wheel 400. The flange 520 is arranged around the outer periphery of the sleeve body 510 and is supported on the top surface of the housing 200. The fastener is specifically a threaded fastener such as a bolt or a screw, and the number is at least one, and it is connected between the flange 520 and the housing 200. In this embodiment, the axial length of the battery 100 is L1, the axial length of the guide sleeve 500 is L2, and the gap between the sleeve body 510 and the grinding wheel 400 is L3, L1>L2+L3, so that after the battery 100 is inserted into the guide sleeve 500, the upper end of the battery 100 can protrude relative to the top of the guide sleeve 500, which is convenient for taking and placing the battery 100.

[0038] Furthermore, the rotary drive member 300 is a rotary motor, the rotation axis of the rotary drive member 300 is perpendicular to the vertical direction, the grinding wheel 400 can specifically be a grinding wheel, and the grinding wheel 400 is coaxially sleeved on the output end of the rotary drive member 300. In this embodiment, in order to facilitate the fixing of the rotary drive member 300, a mounting plate 600 is provided in the mounting cavity 210, the plate surface of the mounting plate 600 is perpendicular to the rotation axis of the rotary drive member 300, and the rotary drive member 300 is fixedly connected to the mounting plate 600.

[0039] Preferably, the mounting plate 600 is suitable for dividing the mounting cavity 210 into a first cavity 211 and a second cavity 212, the rotary drive member 300 is accommodated in the first cavity 211 and fixedly connected to the mounting plate 600, the grinding wheel 400 is accommodated in the second cavity 212, the mounting plate 600 is provided with an opening corresponding to the output end of the rotary drive member 300, the output end of the rotary drive member 300 extends into the second cavity 212 through the opening of the mounting plate 600, and is fixedly connected to the grinding wheel 400. By adopting the above structure, the waste chips polished by the grinding wheel 400 can be blocked to be concentrated in the second cavity 212, so as to facilitate the discharge of the waste chips and avoid the rotary drive member 300 from being damaged by flowing to the rotary drive member 300.

[0040] Furthermore, a handle 700 is provided on the top surface of the housing 200, so as to facilitate the overall movement of the grinder and improve portability. A waste outlet 230 is provided at the position corresponding to the grinding wheel 400 on the bottom surface of the housing 200, and the waste outlet 230 is communicated with the mounting cavity 210. The waste generated by the grinding battery 100 can fall into the waste outlet 230 and flow out of the housing 200. Preferably, in order to facilitate the guidance of the waste to the waste outlet 230, a bucket-shaped collecting trough (not shown) can be provided at the bottom of the second cavity 212, the top of the collecting trough is located below the grinding wheel 400, and covers the entire grinding wheel 400, and the bottom of the collecting trough is communicated with the waste outlet 230. In addition, in order to avoid blocking the waste outlet 230, a plurality of column feet (not shown) can be provided at the bottom of the housing 200, so that there is a certain gap between the bottom surface of the housing 200 and the external bearing surface.

[0041] Furthermore, to facilitate assembly, the casing 200 includes a casing body 240 and a side cover plate 250. The socket 220 and the waste outlet 230 are both formed on the casing body 240. A mounting port 260 is provided on the side of the casing body 240. The rotating drive member 300, the grinding wheel 400 and the mounting plate 600 can all be installed in the mounting cavity 210 through the mounting port 260. The side cover plate 250 is detachably connected to the casing body 240 and is suitable for covering or opening the mounting port 260.

[0042] In addition, the battery grinder also includes a rectifier 800 and a switch 900. The rectifier 800 is fixed on the housing 200. The rectifier 800 can be arranged in the first cavity 211 of the installation cavity 210 or outside the installation cavity 210 as needed. The rectifier 800 is electrically connected to the rotating drive member 300. The rectifier 800 can convert AC power into DC power to provide DC power to the rotating drive member 300, thereby better realizing the speed change of the rotating drive member 300 and being more efficient. The switch 900 is arranged on the top surface of the housing 200. The switch 900 partly extends to the installation cavity 210 and is electrically connected to the rotating drive member 300. The switch 900 can control the start and stop of the rotating drive member 300. Preferably, the switch 900 and the socket 220 are arranged on both sides of the housing 200 to prevent the operator from accidentally touching the switch 900 when grinding the battery 100. In one embodiment, the grinder is connected to a power source via an electrical plug to power the rotating drive member 300. Of course, in other embodiments, the grinder may also be provided with an energy storage structure such as a battery pack to provide electrical energy for the rotating drive member 300 to improve the convenience of the grinder.

[0043] The working process of the battery grinder of the utility model is as follows: the switch member 900 is turned to the open state, and the rotating driving member 300 drives the grinding wheel 400 to rotate; then, one end of the battery 100 is inserted into the guide sleeve 500, and the end of the battery 100 is made to contact with the grinding wheel 400, and the grinding wheel 400 can grind the welding point at the end of the battery 100. During this process, the battery 100 is rotated forward and backward several times to ensure that the welding point is polished flat; then, the battery 100 is pulled out of the guide sleeve 500, and the other end of the battery 100 is inserted into the guide sleeve 500, and the above actions are repeated to grind the other end flat; finally, the polished battery 100 is taken out, and the battery 100 to be polished is put back.

[0044] The above description is only an implementation method of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
