[0029] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0030] Reference Figure 1-5A grinding device 100 specially equipped for a composite material box cover T set includes: an electric grinder 101, a sandpaper sheet 102, a connecting shaft 103, a screw rod 104, a limiting plate 105, a mounting shaft 106, a bearing 107, a pressing plate 108, a nut 109 and a fixing member for fixing the bearing 107 to the mounting shaft 106. The connecting shaft 103 is fixedly connected to the output shaft of the electric grinder 101. The screw rod 104 is fixedly connected to the connecting shaft 103. The connecting shaft 103 is located at the upper end of the screw rod 104, and the limiting plate 105 is located at the lower end of the screw rod 104. The limiting plate 105 is fixedly connected to the screw rod 104. The mounting shaft 106 is fixedly connected to the limiting plate 105. The bearing 107 is sleeved on the mounting shaft 106. The pressing plate 108 is sleeved on the screw rod 104. The nut 109 is threadedly connected to the screw rod 104. Tighten the nut 109 , and the nut 109 will fix the pressing plate 108 and the sandpaper sheet 102 to the limiting plate 105 .

[0031] Among them, the pressing plate 108 is located at the upper end of the sandpaper sheet 102, the limiting plate 105 is located at the lower end of the sandpaper sheet 102, and the sandpaper sheet 102 is fixed to the limiting plate 105 by a nut 109. The pressing plate 108 includes a first air avoidance hole, and the first air avoidance hole is for the screw 104 to pass through. A pressure sensor is provided on the pressing plate 108, and the electric grinder 101 includes: a control board, a drive motor and a lithium battery. The pressure sensor is connected to the control board signal. The drive motor is electrically connected to the lithium battery, and the control board is electrically connected to the lithium battery. The pressure sensor can set the pressure value. When the detected pressure is too large or too small, the control board will stop the drive motor, so that the output shaft of the electric grinder 101 stops rotating, so that the sandpaper sheet 102 no longer grinds the composite material box cover 115, preventing the manual operation of different hand-held pressures from causing inconsistent grinding depths, so that the grinding effect is better.

[0032] The fixing member is used to fix the bearing 107 to the installation shaft 106, and includes: a fastening block 110, a transmission column 112, a driving disk 113, and a screw 114. The fastening block 110 is radially slidably connected to the installation shaft 106. Specifically, the installation shaft 106 is provided with a first slide groove 106a extending radially along the installation shaft 106, and the fastening block 110 moves along the first slide groove 106a. The transmission column 112 is fixedly connected to the fastening block 110. There are multiple transmission columns 112, and the multiple transmission columns 112 are equidistantly distributed along the circumferential direction of the installation shaft 106. The driving disk 113 is rotatably connected to the installation shaft 106. The driving disk 113 is provided with a second air avoidance hole, and the second air avoidance hole is for the screw 114 to pass through. The screw 114 is threadedly connected to the installation shaft 106. The driving disk 113 is provided with a guide groove 113a extending radially and axially along the driving disk 113, and the transmission column 112 is located in the guide groove 113a. The driving disk 113 is rotated to drive the transmission column 112 to move through the guide groove 113a, and the fastening block 110 moves along the first slide groove 106a. Therefore, the movement of the transmission column 112 will drive the fastening block 110 to move along the first slide groove 106a. Then, the screw 114 is tightened to fix the driving disk 113 and the mounting shaft 106 to prevent the transmission column 112 from loosening, thereby fixing the inner ring of the bearing 107, which is more convenient for fixing the bearing 107.

[0033] Working process: Tighten the nut 109, and the nut 109 will move the pressure plate 108, thereby fixing the sandpaper 102 and the limit plate 105. Then the electric grinder 101 is positioned through the outer ring of the bearing 107, and then the output shaft of the electric grinder 101 will drive the connecting shaft 103 to rotate, and the rotation of the connecting shaft 103 will drive the screw 104 and the limit plate to rotate, thereby driving the pressure plate 108 and the sandpaper 102 to rotate. At the same time, the outer ring of the bearing 107 will abut against the inner hole of the composite material box cover 115 for positioning, and the outer ring of the bearing 107 will not rotate, and the inner ring of the bearing 107 will rotate together with the installation shaft 106 and the limit plate 105 to avoid wear and damage to the aperture of the composite material box cover 115, and the positioning is prevented by the bearing 107 to prevent the grinding range from exceeding the bonding area of ​​the T sleeve ( Figure 3 A), thereby ensuring the grinding effect.
