[0018] The following further describes the present utility model in conjunction with the attached Figures 1-4 drawings:

[0019] A multi-functional integrated gripper for an automotive brake disc, hub bearing and steering knuckle, comprising two mounting plates 4 symmetrically and slidably connected to a slide table 2. The mounting plates 4 are provided with weight-reducing holes. The two mounting plates 4 are respectively fixed on two slide seats, and the slide seats are slidably connected to the slide table 2. Driving nuts with reverse threads are respectively arranged on the two slide seats. The driving nuts are threadedly connected to driving lead screws, and the driving lead screws are connected to a servo motor 3. By setting the reverse driving nuts, the two mounting plates 4 can move simultaneously at a constant rate and in opposite directions. A steering knuckle gripping mechanism, a brake disc gripping mechanism and a hub bearing gripping mechanism are mounted on the mounting plates 4. The slide table 2 is connected to a robot through a connecting flange 1, and the robot drives the whole integrated gripper to move.

[0020] The steering knuckle gripping mechanism includes parallel opening and closing cylinders 5 oppositely arranged at both ends of the mounting plate 4. The output ends of the parallel opening and closing cylinders 5 are connected to oppositely arranged clamping blocks 6, and positioning pins 7 are arranged on the clamping blocks 6. After the servo motor 3 drives the clamping blocks 6 to move in place through the mounting plate 4, the part of the steering knuckle to be clamped is located between the two clamping blocks 6, the positioning pins 7 are aligned with the positioning holes on the steering knuckle, and the parallel opening and closing cylinders 5 drive the two clamping blocks 6 to move relatively to clamp the steering knuckle. At the same time, the positioning pins 7 are inserted into the positioning holes. The gripping action of the steering knuckle is completed, and the robot drives the steering knuckle to move to a predetermined working position through the steering knuckle gripping mechanism.

[0021] The brake disc gripping mechanism includes clamping columns a8. Two clamping columns a8 are arranged on the side of each mounting plate 4. The four clamping columns a8 on the two mounting plates 4 form a rectangle when connected. Before gripping the brake disc, the robot first moves the brake disc gripping mechanism in place. After moving in place, the brake disc is located within the rectangular area surrounded by the four clamping columns a8, and the mounting plate 4 drives the clamping columns a8 to move relatively, and the clamping columns a8 clamp the brake disc from the side.

[0022] The hub bearing gripping mechanism includes a relatively arranged first clamping unit and a relatively arranged second clamping unit:

[0023] The first clamping unit includes a mounting bracket a9 fixed on the mounting plate 4. A clamping column b11 is fixed on the mounting bracket a9. A clamping rod 20 is provided at the end of the clamping column b11. An end cap 13 is provided at the end of the clamping rod 20. A tapered ring 15 is movably sleeved on the clamping rod 20. A spring a14 is sleeved on the clamping rod 20 between the tapered ring 15 and the end cap 13. The diameter of the clamping rod 20 is smaller than that of the clamping column b11. The end face of the clamping column b11 is the limiting end face of the tapered ring 15. When the first clamping unit clamps the hub bearing, the bracket a9 moves towards each other under the drive of the mounting plate 4. The bracket a9 drives the clamping column b11 and the clamping rod 20 to move towards each other. The outer surface of the tapered ring 15 at the end of the clamping rod 20 first contacts the outer edge of the hub bearing. The outer surface guides the hub bearing. The hub bearing moves towards the clamping rod 20 along the outer surface of the tapered ring 15. During the relative movement between the hub bearing and the tapered ring 15, they interact with each other, pushing the tapered ring 15 to compress the spring a14. The elastic force generated by the compression of the spring a14 acts on the hub bearing through the tapered ring 15. The tapered ring 15 cooperates with the limiting end face to laterally clamp the outer edge of the hub bearing, as Figure 2 shown, while the clamping rod 20 longitudinally clamps the hub bearing.

[0024] To prevent the hub bearing from rotating during the installation process, a second clamping unit is provided to restrict the rotation of the hub bearing. The second clamping unit includes a mounting bracket b10 fixed on the mounting plate 4. A rocker arm 17 is rotatably connected to the mounting bracket b10 through a rotating shaft 16. A spring b18 is provided between the rocker arm 17 and the mounting bracket a9. A limiting block 12 for limiting the rocker arm 17 is provided on the mounting bracket a9. A rubber-coated head 19 for increasing friction is provided at the end of the rocker arm 17. The spring b18 pushes the rocker arm 17 to rotate around the rotating shaft 16, so that the rubber-coated head 19 can fully contact and press against the outer edge surface of the hub bearing, thereby preventing the rotation of the hub bearing. The limiting block 12 is used to limit the over-travel rotation of the rocker arm 17, thereby preventing interference with the hub bearing during the clamping process.

[0025] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
