The main innovation of the automatic turnover positioning equipment of the present application is that it includes a clamping assembly, which has two clamping arms capable of stably clamping the wheel hub. The wheel hub is clamped circumferentially by the two clamping arms and then turned over to adjust the processing posture of the wheel hub. A driving member two is also installed on the clamping assembly. During the turnover of the wheel hub, the driving member two is driven to further improve the clamping force between the two clamping arms to prevent the heavy wheel hub from slipping during the turnover.

[0038] Further, the vertical frame is fixed with a screw rod motor assembly 8, which includes a screw rod, a linear guide rail and a servo motor and other parts, the screw rod is provided with a sliding block, the sliding block is fixed with the mounting table 6, the two sides of the mounting table 6 are connected and reinforced with the frame through the linear guide rail, the screw rod rotation can drive the sliding block to move up and down to drive the mounting table 6 to move up and down, and the linear guide rail can increase the stability in the sliding process. The mounting table 6 is fixed with a turnover motor 7, and the clamping assembly 3 is connected to the output shaft of the turnover motor 7 and is driven to turn over by the turnover motor 7. The base 1 of the application is provided with a mounting table 6 which can move up and down in the vertical direction, and the whole clamping assembly 3 is installed on the mounting table 6 and can be driven to move in the vertical direction by the mounting table 6. The design can move vertically upward to avoid collision before the clamping assembly 3 clamps the hub to turn over, which effectively prevents the hub from colliding with the base 1 during turning over. The clamping assembly 3 of the application is directly installed on the output shaft of the turnover motor 7, which is directly driven by the turnover motor 7 with high efficiency and reliable stability.

[0039] Further, the driving member two 5 is a connecting disc 51 and two connecting rods 52, the connecting disc 51 is fixed with the output shaft of the turnover motor 7, the two ends of the two connecting rods 52 are respectively hinged on the opposite two ends of the connecting disc 51, and the other ends of the two connecting rods 52 are respectively hinged with the two clamping arms 31, and the torque of the output shaft of the turnover motor 7 is transmitted to the two clamping arms 31 to improve the clamping force. The driving member two 5 of the application is a connecting disc 51 and two connecting rods 52, the connecting disc 51 is fixedly connected with the end of the output shaft of the turnover motor 7, and the two connecting rods 52 are hinged on the opposite two ends of the connecting disc 51, and then the other ends of the two connecting rods 52 are respectively hinged with the two clamping arms 31. The torque of the output shaft of the turnover motor 7 in the rotating process can be transmitted to the two clamping arms 31 through the connecting rods 52 to give the two clamping arms 31 a mutual tensioning force. The turnover motor 7 pulls the two clamping arms 31 to further clamp during the turnover process to provide greater clamping force to make the heavier hub more stable and reliable during the turnover process. Preferably, the two connecting rods 52 are arranged along the moving path direction of the two clamping arms 31 moving towards each other or away from each other, and the two connecting rods 52 are vertically staggered during the turnover process. The arrangement direction of the two connecting rods 52 is the same as the moving direction of the clamping arm 31, so that the hinged end of the two connecting rods 52 is pulled to the center during the rotation of the connecting disc 51. The other end of the connecting rod 52 will pull the corresponding clamping arm 31 towards the center, so that the two clamping arms 31 on both sides move towards the center, which corresponds to increase the clamping force to cope with the automatic stable turnover of the heavier hub.

[0040] Further, the output shaft of the turnover motor 7 is sleeved with a bearing plate 33. It can be changed that the bearing plate 33 can be sleeved on the output shaft or the front end of the turnover motor 7. In theory, when it is on the output shaft, a bearing is preferably installed to ensure independent rotation of the two and to have a certain load bearing effect. In short, the bearing plate 33 can have a certain supporting relationship with the turnover motor 7 or other components, but needs to remain relatively independent during rotation. The two clamping arms 31 are slidingly connected to the bearing plate 33, and the driving member one 32 is connected between the two clamping arms 31 to drive the two clamping arms 31 to move closer or farther away from each other. The turnover motor 7 of the present application has a sleeving relationship with the bearing plate 33 and does not drive it to rotate. The clamping arms 31 are slidingly connected to the bearing plate 33 and are driven to clamp by the driving member one 32. This design enables the clamping arms 31 to be driven by the connecting rod 52 to rotate the bearing plate 33 as a whole when the output shaft of the turnover motor 7 rotates. This provides greater pulling force to the clamping arms 31 during rotation, thereby clamping the hub for turnover.

[0041] Preferably, the opposite sides of the two clamping arms 31 are each provided with a pad 34, and the side profile of the pad 34 can cooperate with the side of the hub. The two clamping arms 31 of the present application are fixed with pads 34 adapted to the hub. The pad 34 can improve the friction force, making the clamping and turnover process more stable. At the same time, the pad 34 can avoid rigid contact between the clamping arm 31 and the hub, effectively reducing the impact and wear, and improving the yield. Preferably, the driving member one 32 and the driving member two 5 are arranged in an up-down arrangement. The driving member one 32 and the driving member two 5 of the present application are arranged in an up-down staggered arrangement. This can provide corresponding pulling force to the upper end and lower end of the clamping arm 31 to make the clamping arm 31 more stable when it is in contact with the hub, and the force is more evenly distributed, which helps to provide stable clamping and prevents the hub from sliding sideways during turnover, effectively improving safety and stability.

[0042] Further, the feeding station is provided with an inner support clamp 2.
