[0021] The abrasive dust collecting device for brake pad grinding machine, as shown in Figure 1 and Figure 2 The support frame 1 is in a U-shaped structure fixedly connected by two parallel transverse vertical plates 11 and a longitudinal vertical plate 12. The feeding device 2 is arranged to slide up and down between the two parallel transverse vertical plates 11 through an electric sliding block. The rotating grinding wheel 4 is arranged on the longitudinal vertical plate 12 above the feeding device 2 through a rotating shaft 13. The rotating grinding wheel 4 is fixedly sleeved on the rotating shaft 3, and a dust cover 8 is arranged on the rotating grinding wheel 4 and the rotating shaft 3. The front end face and the rear end face of the dust cover 8 are fixedly connected with the two transverse vertical plates 11, respectively.

[0022] As shown in Figure 3 The feeding device 2 includes a linear drive motor 22 fixed to the left end face of the feeding groove 21, and two limiting columns 211 arranged horizontally at the front end part and the rear end part of the feeding groove 21, respectively. The right end face of the feeding groove 21 is open.

[0023] As shown in Figure 4 The rotating shaft 3 is hollow inside, and the fan blade 7 is fixedly arranged in the hollow cavity of the rotating shaft 3 through a connecting rod. The fan blade 7 can rotate with the rotation of the rotating shaft 3.

[0024] The right end part of the rotating shaft 3 is fixedly connected with the abrasive dust collecting bag 5 through a bearing penetrating through the longitudinal vertical plate 12. The left end part of the rotating shaft 3 is suspended and can be slidingly connected with the dust cover 8 through an annular slide rail. The rotating grinding wheel 4 is fixedly sleeved on the rotating shaft 3 and rotates with the rotation of the rotating shaft 3. The rotating shaft 3 is rotated through the transmission device 6 fixed on the longitudinal vertical plate 12. The transmission motor 61 on the transmission device 6 is fixed on the longitudinal vertical plate 12. The motor shaft of the transmission motor 61 is fixedly connected with the gear 62 penetrating through the longitudinal vertical plate 12. The gear 62 is engaged with the gear teeth on the rotating shaft 3, so that the rotating shaft 3 can rotate under the start of the transmission device 6.

[0025] In use, first, the feeding device 2 is lowered through the electric sliding block, then the brake pads whose inner arc surfaces need to be polished are placed side by side in the material placing groove 21 of the feeding device 2, and the two side end faces of the brake pads are placed below the limiting column 211;

[0026] Then the feeding device 2 is lifted through the electric sliding block, the brake pads are pushed to the front of the rotating grinding wheel 4 through the linear drive motor 22, until the lower end face of the rotating grinding wheel 4 abuts against the inner arc surface of the brake pad, then the transmission motor 61 on the transmission device 6 is started, so that the gear 62 rotates, because the gear teeth 31 on the rotating shaft 3 are engaged with the gear 62, so the rotating shaft 3 can be driven to rotate, and then the rotating grinding wheel 4 on the rotating shaft 3 rotates, that is, the rotating grinding wheel 4 polishes the inner arc surface of the brake pad;

[0027] When the rotating shaft 3 rotates, the fan blade 7 in the rotating shaft 3 rotates, that is, the air outside the rotating shaft 3 is sucked into the rotating shaft 3 until it reaches the grinding dust collecting bag 5, so when the rotating grinding wheel 4 rotates to polish the brake pad to produce grinding dust, the rotation of the fan blade 7 in the rotating shaft 3 can make the grinding dust be sucked into the rotating shaft 3 until it reaches the grinding dust collecting bag 5.

[0028] And the through hole is arranged on the rotating shaft 3, which can increase the grinding dust suction range and reduce the possibility of grinding dust diffusion.
