[0002] With the continuous prosperity of the new energy storage market, the domestic and foreign energy storage markets are also developing rapidly. During the process of shipping energy storage cabinets from China to foreign countries, they often collide with each other, resulting in surface defects of energy storage cabinets. Therefore, the surface defects need to be polished. The existing polishing mechanism uses bolts to connect the grinding head to the motor, which results in slow disassembly and assembly of the grinding head, affecting the polishing efficiency. Utility Model Content

[0003] In view of the defects of the prior art, the purpose of this application is to provide a grinding mechanism and a grinding device, which can effectively solve the problem of slow assembly and disassembly speed of the grinding head. This purpose is achieved by:

[0004] In a first aspect, the present application provides a grinding mechanism, comprising:

[0005] Mounting frame;

[0007] The grinding head assembly comprises a grinding head body, the grinding head body is provided with a second connecting part, and the first connecting part is magnetically connected to the second connecting part.

[0008] According to the grinding mechanism of the present application, the motor shaft of the drive motor and the grinding head body can be quickly connected by magnetically connecting the first connecting part and the second connecting part, and the motor shaft of the drive motor and the grinding head body can be quickly disassembled by disconnecting the magnetic connection between the first connecting part and the second connecting part, thereby improving the disassembly and assembly speed of the motor shaft of the drive motor and the grinding head body.

[0009] In some other embodiments of the present application, the drive assembly further includes a first connecting member, which is disposed on the end surface of the motor shaft facing the grinding head body, and the first connecting member forms a first connecting portion on at least a portion of the surface of the grinding head body.

[0010] By forming the first connecting part on the first connecting member and connecting the first connecting member to the end face of the motor shaft facing the grinding head body, the formation and position adjustment of the first connecting part are facilitated. At the same time, when the first connecting part is damaged, such as being unable to be magnetically connected to the second connecting part, the first connecting part can be replaced by replacing the first connecting member, thereby replacing a new first connecting part without replacing the motor shaft or the drive motor.

[0011] In some other embodiments of the present application, the grinding head assembly further includes a second connecting member, which is disposed on a side of the grinding head body facing the drive motor, and the second connecting member forms a second connecting portion on at least a portion of the surface facing the first connecting member.

[0012] By forming the second connecting part on the second connecting member and arranging the second connecting member on the side of the grinding head body facing the drive motor, the formation and position adjustment of the second connecting part are facilitated. At the same time, when the second connecting part is damaged, such as being unable to be magnetically connected to the first connecting part, the second connecting member can be replaced to replace the new second connecting part without replacing the grinding head body.

[0013] In some other embodiments of the present application, part of the second connection portion is recessed in a direction away from the first connection portion to form a first installation groove, and at least part of the first connection portion is inserted into the first installation groove.

[0014] By recessing the second connecting part in a direction away from the first connecting part and forming a first installation groove, the first connecting part can be inserted into the first installation groove and magnetically connected to the second connecting part, thereby facilitating the positioning and installation of the first connecting part and the second connecting part, and can reduce the displacement of the first connecting part and the second connecting part in a direction perpendicular to the motor shaft, thereby improving the connection reliability between the first connecting part and the second connecting part.

[0015] In some other embodiments of the present application, the motor shaft is further provided with a first limiting portion, and the grinding head body is further provided with a second limiting portion. The first limiting portion cooperates with the second limiting portion and is used to limit the rotation of the grinding head body around the axis of the motor shaft.

[0016] By matching the first limit portion with the second limit portion, the rotation of the grinding head body around the axis of the motor shaft can be limited, thereby reducing the phenomenon that the rotation speed of the grinding head body is lower than the rotation speed of the motor shaft due to the friction between the grinding head body and the surface to be rubbed, thereby improving the reliability of the grinding mechanism during operation.

[0017] In some other embodiments of the present application, the drive assembly also includes a first limit member, which is sleeved on the outer periphery of the motor shaft, and in a plane perpendicular to the axis of the motor shaft, the projection of at least part of the first limit member exceeds the outer contour of the projection of the first connecting portion, and forms a first limit portion.

[0018] By forming the first limiting portion on the first limiting member and sleeved the first limiting member on the outer periphery of the motor shaft, the formation of the first limiting portion and the adjustment of the position are facilitated. At the same time, when the first limiting portion is damaged, such as being unable to cooperate with the second limiting portion, the first limiting portion can be replaced by replacing the first limiting member without replacing the motor shaft or the drive motor.

[0019] In some other embodiments of the present application, the second limiting portion is arranged around the outer circumference of the second connecting portion and is integrally formed with the second connecting portion.

[0020] By annularly arranging the second limiting portion on the outer periphery of the second connecting portion, the limiting cooperation between the first limiting portion and the second limiting portion is facilitated. At the same time, the second limiting portion and the second connecting portion are integrally formed, which can improve the connection strength between the second limiting portion and the second connecting portion and reduce the displacement of the second limiting portion and the second connecting portion in a direction perpendicular to the motor shaft.

[0021] In some other embodiments of the present application, a second mounting groove is provided on a surface of the second limiting portion facing the first limiting portion, and at least a portion of the first limiting portion is inserted into the second mounting groove.

[0022] By providing a second mounting groove on the surface of the second limiting portion facing the first limiting portion, at least a portion of the first limiting portion can be inserted into the second mounting groove, thereby facilitating the positioning and cooperation of the first limiting portion and the second limiting portion, and reducing the displacement of the first limiting portion and the second limiting portion in a direction perpendicular to the motor shaft, thereby limiting the rotation of the grinding head body around the axis of the motor shaft.

[0023] In some other embodiments of the present application, the second limiting portion is provided with a plurality of protruding ends protruding toward the surface of the first limiting portion, any one of the protruding ends extends to the side of the second connecting portion facing the first connecting portion, a plurality of protruding end spacing rings are arranged on the outer periphery of the second connecting portion, and a second installation groove is formed between any two adjacent protruding ends.

[0024] By extending the protruding end to the side of the second connection part facing the first connection part and forming a second installation groove between any two adjacent protruding ends, the first limiting part is easily inserted into the second installation groove, thereby facilitating the positioning and matching of the first limiting part and the second limiting part.

[0025] In some other embodiments of the present application, there are multiple first limiting portions, and multiple first limiting portion spacing rings are arranged on the outer periphery of the motor shaft. In a plane perpendicular to the axis of the motor shaft, the outer contour size of the first limiting portion gradually increases along the direction of the motor shaft toward the first limiting portion. There are multiple second mounting grooves, and the multiple second mounting grooves are arranged one-to-one and matched with the multiple first limiting portions.

[0026] By gradually increasing the outer contour size of the first limiting portion along the direction of the motor shaft toward the first limiting portion, and arranging and cooperating with multiple second mounting grooves in a one-to-one correspondence with multiple first limiting portions, the shear force between the second limiting portion and the first limiting portion can be reduced when the driving motor drives the grinding head body to rotate, thereby reducing damage to the first limiting portion and the second limiting portion.

[0027] In some other embodiments of the present application, the first connecting part includes a magnet, and the second connecting part includes a magnetizable member that can be magnetically connected to the magnet.

[0028] By setting the first connecting part as a magnet and the second connecting part as a magnetizable part that can be magnetically connected to the magnet, the first connecting part and the second connecting part can be magnetically connected. At the same time, the first connecting part is arranged farther away from the grinding head body than the second connecting part, and the second connecting part is set as a magnetizable part, which can reduce the magnetic connection between the magnetic material that falls during the grinding process and the second connecting part.

[0029] In some other embodiments of the present application, the mounting frame includes a support plate and a fixed frame, the fixed frame is arranged on one side of the support plate and forms a mounting cavity with the support plate, a slide groove is provided on the other side of the support plate away from the fixed frame, the motor seat of the drive motor is arranged in the mounting cavity, the motor shaft of the drive motor passes through the support plate and extends into the slide groove, and the second connecting part is slidably arranged in the slide groove and is magnetically connected to the first connecting part.

[0030] By slidably arranging the second connecting part in the slide groove, during the connection process of the drive assembly and the grinding head assembly, the drive motor can be placed in the installation cavity on one side of the support plate, and the grinding head body can be placed on the other side of the support plate. The second connecting part can be slid in the slide groove to adjust the relative position of the grinding head body and the drive motor, and then the connection between the grinding head body and the drive motor is achieved through the magnetic connection between the first connecting part and the second connecting part.
