[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0030] like Figures 1 to 7 As shown, an automated production line for automobile wheel hubs includes a water-cooling tray 1. A first turning machine 2, a second turning machine 3, and a drilling machine 4 are arranged around the water-cooling tray 1. A joint base 5 is provided on the surface of the water-cooling tray 1. A five-axis robotic arm 6 is provided on the joint base 5. A robot connecting plate 7 is provided at the end of the five-axis robotic arm 6. A set of wheel hub gripper assemblies is provided on both sides of the robot connecting plate 7. A feeding roller line 8 and a discharging roller line 9 are provided on the side of the water-cooling tray 1 away from the wheel hub gripper assemblies. A wheel hub positioning assembly is provided between the feeding roller line 8 and the discharging roller line 9.

[0031] In operation, the wheel hub is moved to the designated position via the loading roller conveyor 8. The five-axis robotic arm 6 picks up the wheel hub using the wheel hub gripper assembly and places it onto the wheel hub positioning assembly. The wheel hub positioning assembly performs angular positioning on the wheel hub to be processed. The wheel hub gripper assembly picks up the wheel hub that has completed angular positioning and waits for the protective door of the first turning machine tool 2 to open before placing the wheel hub in. Simultaneously, since there are two sets of wheel hub gripper assemblies, the idle set can pick up another wheel hub that has completed angular positioning, waiting for the wheel hub to be processed by the first turning machine tool 2. After the first machining process is completed, the wheel hub is taken out and placed into the second turning machine 3. The wheel hub with angular positioning completed is placed into the first turning machine 2. The wheel hub with the second machining process is taken out and placed into the drilling machine 4. The wheel hub with the first machining process is taken out and placed into the second turning machine 3. The wheel hub with the drilling process completed is taken out and placed into the unloading roller line 9. The wheel hub with the second machining process completed is taken out and placed into the drilling machine 4. After the drilling is completed, it is also placed into the unloading roller line 9. This process is repeated.

[0032] The design of the loading roller conveyor 8 and unloading roller conveyor 9 allows wheel hubs to enter and leave the production line smoothly and orderly, reducing the time and cost of manual handling. The five-axis robotic arm 6 can perform complex movements in three-dimensional space, precisely gripping, transporting, and positioning the wheel hubs, thereby greatly improving processing efficiency. The first turning machine 2, the second turning machine 3, and the drilling machine 4 are all high-precision equipment, ensuring that all parts of the wheel hub meet design requirements. During processing, the wheel hub positioning assembly ensures that the wheel hub is in the correct position, preventing processing errors caused by positional deviations. The joint base 5 provides stable support for the five-axis robotic arm 6.

[0033] The hub gripper assembly includes a square tube 10, a movable plate 11, an adjusting block 12, and a gripper 13. The square tube 10 is bolted to the robot connecting plate 7. There are two movable plates 11, which are slidably installed on the square tube 10. The adjusting block 12 is adjustablely installed on the movable plate 11. There are two grippers 13, which are bolted to an adjusting block 12.

[0034] The wheel hub gripper assembly can achieve precise gripping and placement of the wheel hub through the coordinated action of the adjusting block 12, the movable plate 11 and the gripper 13. The adjusting assembly can be used to adjust the movable plate 11 to adapt to the gripping needs of wheel hubs of different sizes and weights. The square tube 10 provides support for the movable plate 11 and other components.

[0035] The wheel hub positioning assembly includes an aluminum profile bracket 14, a platform 15 on the top of the aluminum profile bracket 14, a driving helical gear 16 on the platform 15, a guide shaft 17 on the driving helical gear 16, a plurality of driven helical gears 18 around the guide shaft 17, a roller 19 rotatably connected to one side of the driven helical gears 18, a mounting assembly for mounting the roller 19 is provided on the roller 19, and a driving assembly for driving the driving helical gear 16 is provided on the driving helical gear 16.

[0036] The drive assembly provides power to the active helical gear 16, which in turn drives the driven helical gear 18 to rotate, which in turn drives the roller 19 to rotate. The guide shaft 17 guides the hub. The above components work together to provide angular positioning for the hub, allowing the hub gripped by the hub gripper assembly to be processed according to a predetermined program.

[0037] The mounting assembly includes a first fixed base 20, a second fixed base 21, a fixed base pad 22, a support pad 23, and several connecting plates 24. The first fixed base 20 is located at one end of the opposing driven helical gear 18, and the second fixed base 21 is located at one end of the distancing driven helical gear 18. The top bolt of the fixed base pad 22 is fixed to the second fixed base 21, and its bottom bolt is fixed to the platform 15. The top bolt of the support pad 23 is fixed to the first fixed base 20, and its bottom bolt is fixed to the connecting plates 24.

[0038] The first fixed seat 20 and the second fixed seat 21 are respectively located at one end of the driven helical gear 18 facing each other and apart. This design effectively disperses the pressure of the roller 19 and the load it bears, and enhances the stability of the roller 19 installation. The use of the fixed seat pad 22 and the support pad 23 provides additional support, further enhancing the stability of the roller 19 installation.

[0039] The drive assembly includes a geared motor 25, a motor mounting base 26, a rotating drum 27, a rotating shaft 28, and a transition plate 29. The geared motor 25 is located below the platform 15. The bottom of the motor mounting base 26 is bolted to the geared motor 25, and its top is bolted to the rotating drum 27. The rotating drum 27 extends upward to the surface of the platform 15. The top of the transition plate 29 is connected to the drive helical gear 16, and its bottom is connected to the rotating shaft 28. The rotating shaft 28 is located on the surface of the rotating drum 27, and the connecting plate 24 is arranged along the circumference of the rotating drum 27.

[0040] The geared motor 25 provides stable speed and torque output, ensuring that the drive helical gear 16 rotates at the appropriate speed and force. The motor mounting base 26 securely mounts the geared motor 25 below the table 15, while the rotating drum 27 extends upwards onto the surface of the table 15, providing solid support for the rotating shaft 28 and the transition plate 29.

[0041] A protective sheet metal 30 is provided on the surface of the support pad 23; the protective sheet metal 30 can protect the corresponding components.

[0042] A visual positioning component is provided on one side of the aluminum profile bracket 14. The visual positioning component includes a side bracket 31 provided on one side of the aluminum profile bracket 14. A camera fixing sheet metal 32 is provided on the side bracket 31. A laser camera 33 is provided on the camera fixing sheet metal 32. A light source fixing sheet metal 34 is provided on the top of the side bracket 31. A high-definition camera 35 is provided on the surface of the light source fixing sheet metal 34. An open light source 36 is provided at its bottom. A light shield 37 is provided around the open light source 36.

[0043] The laser camera 33 has high-precision measurement and positioning capabilities, and can capture clear images and videos. It can clearly determine whether the wheel hub placed on the wheel hub positioning assembly has completed angular positioning. The open light source 36 provides sufficient illumination for the camera, ensuring the brightness and clarity of the captured image. The open design helps to distribute light evenly and reduce shadows and reflections. The high-definition camera 35, which is fixed to the surface of the light source sheet metal 34, can compensate for the defects of the laser camera 33 from different angles or make up for the blind spots of the laser camera 33, providing more comprehensive monitoring information. The light shield 37 can effectively block external stray light from entering the camera.

[0044] A blower 38 is installed between the first turning machine tool 2 and the second turning machine tool 3; after the turning machine tool has finished processing, the blower 38 can blow away aluminum chips from the wheel center hole and inner rim.

[0045] A thickness measuring machine 39 is installed between the second turning machine 3 and the drilling machine 4; the thickness measuring machine 39 can automatically measure the thickness of the wheel hub, which is beneficial to improving the yield of materials.
