A rotating shaft 2 is rotatably connected to the inner wall of the mounting bracket 1. One end of the rotating shaft 2 located outside the mounting bracket 1 is fixedly connected to a base 3. A clamping mechanism is installed on the outer wall of the base 3. The clamping mechanism includes two relatively moving fixtures 6 arranged on the outer wall of the base 3. On the outer wall of one side of the two fixtures 6 facing the base 3, racks 8 are fixedly connected. A flipping assembly for driving the base 3 to flip is installed on the inner wall of the mounting bracket 1;

[0024] The flipping assembly includes a driving wheel 15 rotatably connected to the inner wall of the mounting bracket 1. One end of the rotating shaft 2 away from the base 3 is fixedly connected to a driven wheel 14. A synchronous belt 16 is installed in cooperation with the outer walls of the driven wheel 14 and the driving wheel 15. A servo motor 17 is also fixedly installed on the inner wall of the mounting bracket 1. The end of the output shaft of the servo motor 17 is fixedly connected to the outer wall of the driving wheel 15.

[0025] A gear 7 is rotatably connected to the outer wall of the middle section of the base 3. The gear 7 is located between the two racks 8 and meshes with the two racks 8.

[0026] An electric cylinder 9 is also fixedly installed on the outer wall of the base 3. The output end of the electric cylinder 9 is fixedly connected to one of the fixtures 6.

[0027] Two sliding rods 4 are fixedly connected to the inner walls on both sides of the base 3. A plurality of sliders 5 are slidably connected to the outer walls of the sliding rods 4. The sliders 5 are fixedly connected to the outer wall of one side of the fixture 6 facing the base 3.

[0028] A sensing unit is also installed on the outer wall of the base 3. The sensing unit includes a position sensor 10 and an attitude sensor 11 installed on the outer wall of the base 3.

[0029] A controller 12 is installed on the inner wall of the mounting bracket 1. Both the position sensor 10 and the attitude sensor 11 are connected to the signal input end of the controller 12 through data lines. Both the servo motor 17 and the electric cylinder 9 are connected to the signal output end of the controller 12 through wires.

[0030] On one outer wall of the mounting bracket 1 away from the base 3, a plurality of through fixing holes 13 are provided, and the plurality of fixing holes 13 are evenly distributed at the four-corner edge positions of the mounting bracket 1.

[0031] The implementation principle of an intelligent flipping fixture in an embodiment of the present application is as follows: During use, first, the mounting bracket 1 is fixedly installed on the processing equipment through a plurality of fixing holes 13. According to the shape and size of the workpiece, the structure and size of the fixture 6 are adjusted. The workpiece is placed between the two fixtures 6, and the clamping mechanism is started through the controller 12. At this time, the electric cylinder 9 is started, and its output end contracts. (Refer to Figure 2 ) It pulls the left fixture 6 inward. At this time, the left fixture 6 pushes the left rack 8 inward. When the left rack 8 moves inward, it will drive the gear 7 meshing with it to rotate. The gear 7 will drive the right rack 8 inward. The right rack 8 will synchronously pull the right fixture 6 inward. In this way, the two fixtures 6 will move synchronously closer to the workpiece and clamp the workpiece between the two fixtures 6;

[0032] The controller 12 receives the processing instruction and automatically adjusts the angle of the base 3 according to the instruction requirements. The flipping assembly is started. The servo motor 17 drives the driving wheel 15 to rotate through its output shaft. When the driving wheel 15 rotates, it synchronously drives the driven wheel 14 to rotate through the synchronous belt 16. The driven wheel 14 drives the base 3 to rotate through the rotating shaft 2, realizing the flipping operation of the workpiece;

[0033] During the flipping process, the position sensor 10 and the attitude sensor 11 in the sensing unit real-time monitor the position and attitude of the workpiece and send the feedback signal to the controller 12. The controller 12 adjusts the motion parameters of the flipping assembly according to the feedback signal, accurately controls the rotation angle of the servo motor 17, ensures that the workpiece can be accurately and smoothly flipped to the specified position. After the flipping is completed, the controller 12 turns off the flipping assembly and releases the workpiece through the clamping mechanism, completing the entire processing process.
