[0085] More specifically, Figure 1 , Figure 2 and Fig. 9 As shown, in order to make the grinding operation more accurate and effective, the brake disc grinding device also includes a visual mechanism 7, which is arranged on the carrier 1. The visual mechanism 7 performs image recognition on the brake disc 100 to control the rotation angle of the brake disc 100, so as to facilitate the grinding head 621 to extend into the stepped hole 102 for grinding, and the grinding disc 42 to extend into the keyway 101, thereby grinding the keyway 101. Further, the visual mechanism 7 includes a camera and a computer, and the image of the brake disc 100 is captured by the camera, and the image information is transmitted to the computer for image processing to calculate the rotation angle of the brake disc 100, and the control signal is generated by the computer and transmitted to the rotation driver 34, and the brake disc 100 is rotated by the rotation driver 34, so that the grinding head 621 is opposite to the stepped hole 102 on the brake disc 100, or the grinding disc 42 is opposite to the keyway 101, so as to facilitate the subsequent grinding operation, which not only improves the grinding efficiency, but also ensures the quality of the grinding operation. Furthermore, the visual mechanism 7 may also include a photoelectric sensor, an image processing unit, a controller, etc., so as to realize image recognition and rotation angle control of the brake disc 100. That is, the specific structure of the visual mechanism 7 is not limited as long as the above-mentioned functions can be realized.

[0086] Specifically, Fig. 9As shown, the second grinding mechanism 6 also includes an adjusting disk 64 and an adjusting driver 65. The adjusting disk 64 is rotatably connected to the round table 61 and is arranged concentrically with the round table 61. The adjusting disk 64 is provided with a plurality of slide grooves 641, and the plurality of slide grooves 641 are arranged at equal intervals along the circumference of the adjusting disk 64. The grinding member 62 is slidably connected to the round table 61 along the radial direction of the round table 61. The end of the grinding member 62 away from the grinding head 621 is provided with a protruding block 622, and the protruding block 622 extends into the slide groove 641. The output end of the adjusting driver 65 is connected to the adjusting disk 64, and can drive the adjusting disk 64 to rotate. The rotation of the adjusting disk 64 can drive the slide groove 641 to rotate. The groove wall of the slide groove 641 pushes the protruding block 622, and the grinding member 62 can be driven to slide along the radial direction of the adjusting disk 64, so as to adjust the length of the grinding member 62 extending from the round table 61, so that the grinding head 621 can adapt to brake discs 100 of different specifications, so as to facilitate grinding operations and have wider adaptability.

[0087] More specifically, the extension directions of two adjacent slide grooves 641 are set at an angle, and the angles between each two adjacent slide grooves 641 are the same, so as to ensure that the slide grooves 641 can simultaneously push the protruding blocks 622 during the rotation process, thereby achieving the simultaneous sliding of multiple grinding members 62, and extending multiple grinding heads 621 to the same length at the same time to adapt to the grinding of the stepped holes 102. Furthermore, the adjustment driver 65 in this embodiment can adopt a servo motor, a stepping motor or the like, which will not be described in detail here.

[0088] The specific working process of this device is described below:

[0089] Step 1: The brake disc 100 is transported to the clamping station by the lifting and transporting mechanism 2, and the clamping and flipping mechanism 3 clamps and fixes the brake disc 100 and drives the brake disc 100 to flip.

[0090] In the above step one, the slide 22 slides in the vertical direction until the slide 22 is highly flush with the clamping station on the clamping and flipping mechanism 3, and the brake disc 100 is driven to move by the rotation of the roller until the brake disc 100 is placed on the clamping station and maintains a horizontal state; the clamping driver 38 drives the clamping member 37 to abut against the inner circumferential inner wall of the brake disc 100, thereby fixing the brake disc 100 to prevent it from shaking or falling; the turning frame 31 is driven to rotate in the horizontal direction by the flipping driver 32, thereby driving the turntable 33 and the brake disc 100 to achieve a 90-degree flip, so that the brake disc 100 remains in a vertical state.

[0091] Step 2: After the brake disc 100 is kept in a vertical state, the sliding driver 43 drives the grinding disc 42 to extend into the key slot 101 for grinding, and the brake disc 100 is driven to rotate by the rotating driver 34 to complete the grinding operation of the remaining key slots 101.

[0092] In the above step 2, the visual mechanism 7 and the rotating driver 34 cooperate to make the grinding disc 42 just face one of the key slots 101 to ensure the accuracy and precision of the operation. The sliding driver 43 drives the sliding plate 41 to slide in the horizontal direction, thereby driving the grinding disc 42 to extend into the key slot 101. In order for the grinding disc 42 to be able to just extend into the key slot 101, the grinding cylinder drives the grinding disc 42 to grind up and down along the extension direction of the key slot 101, so as to further improve the grinding quality. After the key slot 101 at this location is polished, the sliding driver 43 drives the grinding disc 42 to be pulled out of the key slot 101, and the rotating driver 34 drives the brake disc 100 to rotate to the next key slot 101, and repeats the above actions until all key slots 101 are fully polished.

[0093] Step 3: During the rotation of the brake disc 100 , the rust removal driver 53 drives the laser 52 to rotate so as to remove rust from both sides of the brake disc 100 .

[0094] In the above step three, the brake disc 100 is driven to rotate in a horizontal direction by the rotating driver 34. At the same time, the laser 52 performs rust removal on one side of the brake disc 100. The brake disc 100 rotates and removes rust. After the rust removal on one side of the brake disc 100 is completed, the rust removal driver 53 drives the connecting frame 51 to rotate, thereby driving the laser 52 to rotate in a horizontal direction, thereby performing rust removal on the other side of the brake disc 100, so that the laser 52 can perform laser rust removal on the opposite sides of the brake disc 100, and the operation efficiency is higher.

[0095] Step 4: Control the rotation angle of the brake disc 100 through the visual mechanism 7, and the telescopic driver 63 drives the grinding head 621 to extend into the stepped hole 102 for grinding.

[0096] In the above step four, when the brake disc 100 rotates to the point where the stepped hole 102 is facing the grinding head 621, the visual mechanism 7 stops the rotation of the brake disc 100 by controlling the rotating driver 34, and the telescopic driver 63 drives the table 61 to move toward the brake disc 100 until the grinding head 621 extends into the stepped hole 102 and performs grinding; after the stepped hole 102 at that location is ground, the telescopic driver 63 drives the grinding head 621 to withdraw from the stepped hole 102 to avoid interfering with the rotation of the brake disc 100, and the rotating driver 34 drives the brake disc 100 to rotate in the horizontal direction again. When the visual mechanism 7 identifies the next batch of stepped holes 102 that need to be ground, the rotation of the brake disc 100 is stopped by controlling the rotating driver 34, and the above actions are repeated until all the stepped holes 102 are ground.

[0097] Step 5: The brake disc 100 is driven to flip to the initial state through the clamping and flipping mechanism 3, and the clamping and fixing of the brake disc 100 is released, and the brake disc 100 is transported out of the clamping station through the lifting and transportation mechanism 2.

[0098] It should be noted that the brake disc grinding device of this embodiment reduces the safety hazards such as falling and collision caused by the reciprocating transportation and high-frequency flipping of the brake disc 100. At the same time, the visual mechanism 7 can achieve precise positioning of the brake disc 100, thereby improving the efficiency of the grinding operation.

For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention.
