[0025] In the disclosed embodiment, a track block 1021 with a "T"-shaped cross-section is provided on the top of the tensioning frame 102, and the track block 1021 is slidably connected to the inside of the mounting frame 101. This design can limit the movement trajectory of the tensioning frame 102 inside the mounting frame 101, thereby improving the stability of the device.

[0026] In the embodiment of the present disclosure, a tensioning top spring 1023 is sleeved on the outside of the linkage rod, and the two ends of the tensioning top spring 1023 are respectively against the inside of the mounting frame 101 and the side of the track block 1021. In use, the grinding assembly 1 adopts a belt grinding structure to perform grinding operations on the battery steel shell. Under the action of the tensioning top spring 1023, the mounting frame 101 and the tensioning frame 102 are stretched apart, thereby providing a tensioning grinding force for the grinding belt 106 installed on the driven pulley 103 and the outside of the driving pulley 104. Control gears 2021 are provided on both sides of the control shaft 202, and drive gears 1041 are provided on the outside of the drive motor 105 and the driving pulley 104. The drive motor 105 and the driving pulley 104 are respectively engaged with the gear teeth of the control gears 2021 on both sides of the control shaft 202 for transmission. The driving gear 1041 of the wheel 104 is coaxially arranged. When the battery steel shell is being polished, the operating handle 3 is held and the power of the driving motor 105 is turned on. When the driving motor 105 rotates, the driving gear 1041 on the side of the rotating shaft can drive the control shaft 202 to rotate through the control gear 2021 on the same side of the control shaft 202. When the control shaft 202 rotates, the control gear 2021 on the other side can drive the driving pulley 104 to rotate through the driving gear 1041 on the side of the driving pulley 104.

In use, the control component 2 can limit the maximum grinding pressure of the grinding belt 106 on the battery steel shell. When the grinding pressure is applied, the grinding belt 106 will deform and reduce the distance between the driven pulley 103 and the driving pulley 104 (the tensioning frame 102 and the mounting frame 101). When the distance changes, the tensioning top spring 1023 will be compressed and the control rod 1022 will move inside the control groove 2011. When the control rod 1022 moves in the straight groove part of the control groove 2011, the use position of the control seat 201 will not change, which can ensure that the driving gear 1041 and the control gear 2 021 realizes the grinding operation. When the grinding pressure reaches or exceeds the maximum grinding pressure, the control rod 1022 enters the bevel part of the control groove 2011, and the control rod 1022 can drive the control seat 201 to move upward when moving inside the bevel of the control groove 2011, so that the control seat 201 can drive the control shaft 202 to move upward synchronously when moving upward, and the transmission relationship between the driving gear 1041 and the control gear 2021 is released. Then, the grinding belt 106 will not continue to grind, avoiding the damage of the metal steel shell or the tearing of the grinding belt 106 due to excessive grinding pressure. It is stable to use. At the same time, after the excessive grinding pressure is removed, the grinding component 1 and the control component 2 can automatically reset and restore the grinding state under the action of the tensioning top spring 1023, so as to continue the normal grinding operation on the power supply steel shell.

[0028] The specific usage and function of this embodiment are as follows:

[0029] In the present invention, when it is necessary to grind the battery steel shell, after holding the operating handle 3 and turning on the power of the driving motor 105, the grinding belt 106 can be attached to the part that needs to be polished to perform the grinding operation on the battery steel shell. The grinding assembly 1 adopts a belt-type grinding structure to perform the grinding operation on the battery steel shell. Under the action of the tensioning top spring 1023, the mounting frame 101 and the tensioning frame 102 are stretched open, thereby providing a tensioning and grinding force for the grinding belt 106 installed on the driven pulley 103 and the outside of the driving pulley 104. After the power of the driving motor 105 is turned on, the driving gear 1041 on the side of the rotating shaft of the driving motor 105 can pass through the control shaft 202 when the driving motor 105 rotates. The control gear 2021 on the same side drives the control shaft 202 to rotate. When the control shaft 202 rotates, the control gear 2021 on the other side can drive the driving pulley 104 to rotate through the driving gear 1041 on the side of the driving pulley 104. When the driving pulley 104 rotates, it can cooperate with the driven pulley 103 to drive the grinding belt 106 to move. Thereafter, the grinding belt 106 is attached to the part that needs to be polished to perform the grinding operation on the battery steel shell. In the grinding process, the grinding belt 106 can automatically fit and polish according to the external shape of the battery steel shell. The control component 2 can limit the maximum grinding pressure of the grinding belt 106 on the battery steel shell. When the grinding pressure is applied, the grinding belt 106 is used to polish the battery steel shell. The grinding belt 106 will be deformed and reduce the distance between the driven pulley 103 and the driving pulley 104 (tensioning frame 102 and mounting frame 101). When the distance changes, the tensioning top spring 1023 will be compressed and the control rod 1022 will move inside the control groove 2011. When the control rod 1022 moves in the straight groove part of the control groove 2011, the use position of the control seat 201 will not change, which can ensure the stable transmission between the driving gear 1041 and the control gear 2021 to realize the grinding operation. When the grinding pressure reaches or exceeds the maximum grinding pressure, the control rod 1022 enters the oblique groove part of the control groove 2011, and the control rod When 1022 moves inside the inclined groove of the control groove 2011, it can drive the control seat 201 to move upward, so that the control seat 201 can drive the control shaft 202 to move upward synchronously when moving upward, and the transmission relationship between the driving gear 1041 and the control gear 2021 is released. Then, the grinding belt 106 will not continue to grind thereafter, avoiding damage to the metal steel shell or tearing of the grinding belt 106 due to excessive grinding pressure. It is stable to use. At the same time, after the excessive grinding pressure is removed, the grinding component 1 and the control component 2 can automatically reset and restore the grinding state under the action of the tensioning top spring 1023, so as to continue the normal grinding operation on the power supply steel shell.
