[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] As attached Figure 1 -Attached Figure 8 As shown, an automatic loading and unloading fixture system includes a frame 2, a feeding mechanism 1 is arranged at the rear side of the frame 2, a discharging mechanism 30 is arranged below the feeding mechanism 1, a part of the discharging mechanism 30 is arranged through the frame 2, and there is a gap between the top of the frame 2 and the discharging mechanism 30, and the gap can allow the wheel hub to pass through. A stopper is arranged at the front end of the feeding mechanism 1 to block the wheel hub conveyed by the feeding mechanism 1 and limit it.

[0025] The front side of the feeding mechanism 1 is provided with a mounting seat 9, and a conveying mechanism 10 is installed in the mounting seat 9 through a lifting mechanism 31. The feeding mechanism 1, the discharging mechanism 30 and the conveying mechanism 10 all include a plurality of conveying rollers 32, and the conveying rollers 32 are used to drive the wheel hub to move.

[0026] The upper part of the frame 2 is provided with a chassis 4 through a lateral movement mechanism 3, and a motor 35 is arranged inside the chassis 4. The upper end of the driving shaft of the motor 35 passes through the chassis 4 and is connected to a rotating table 5. A support seat 6 is connected to the middle position of the upper part of the rotating table 5. A lifting mechanism 7 is respectively installed on the front and rear sides of the support seat 6. The lifting mechanism 7 is driven and connected to a clamping mechanism 8. A base 12 is arranged on the side of the frame 2, and a processing table 14 is installed on the base 12 through a moving mechanism 13. A positioning mechanism 15 and a drilling mechanism 16 are also arranged on the base 12.

[0027] The wheel hub to be processed is transported to the rear side of the frame 2 by the feeding mechanism 1. When processing the first wheel hub, the two clamping mechanisms 8 are adjusted to be arranged one in front and one behind. The lifting mechanism 7 controls the clamping mechanism 8 on the rear side to descend, and the wheel hub is clamped by the clamping mechanism 8. The motor 35 controls the rotating table 5 to rotate 90 degrees clockwise. The chassis 4 is then driven by the transverse mechanism 3 to move toward the base 12, so that the clamping mechanism 8 reaches above the processing table 14, and the clamping mechanism 8 on the right side places the wheel hub on the processing table 14. After the placement of the wheel hub is completed, the chassis 4 returns to its original position, and the two clamping mechanisms 8 return to the state of one in front and one behind.

[0028] The processing table 14 is driven to move by the moving mechanism 13, and the processing table 14 first transports the wheel hub to the bottom of the positioning mechanism 15, and the wheel hub is positioned by the positioning mechanism 15. After the positioning is completed, the processing table 14 then transports the wheel hub to the bottom of the drilling mechanism 16, and the wheel hub is drilled by the drilling mechanism 16. After the drilling is completed, the processing table 14 moves to the original position.

[0029] When processing the second wheel hub, the clamping mechanism 8 on the rear side first clamps the wheel hub delivered by the feeding mechanism 1. The motor 35 drives the rotating table 5 to rotate counterclockwise 90 degrees, so that the clamping mechanism 8 holding the wheel hub is on the left, and the empty clamping mechanism 8 is on the right. The transverse mechanism 3 drives the chassis 4 to move toward the base 12, and the empty clamping mechanism 8 reaches above the processing table 14, and the processed wheel hub is clamped by the clamping mechanism 8. Then the transverse mechanism 3 controls the chassis 4 to move away from the base 12 and return to its original position. The motor 35 drives the rotating table 5 to rotate 180 degrees clockwise, so that the clamping mechanism 8 holding the unprocessed wheel hub is on the right, and the wheel hub is first delivered to the processing table 14 to start processing. Since the processing time is long, placing the wheel hub on the processing table 14 first to start processing can reduce the waiting time. No time is wasted in unloading and loading the wheel hub during the processing process. The chassis 4 returns to its original position, and the rotating table 5 rotates 90 degrees counterclockwise, so that the clamping mechanism 8 holding the processed wheel hub reaches above the conveying mechanism 10. The clamping mechanism 8 moves downward, and after being released, the processed wheel hub is placed on the conveying mechanism 10. The lifting mechanism 31 drives the conveying mechanism 10 to descend, so that the conveying mechanism 10 is flush with the discharge mechanism 30 below, and the conveying mechanism 10 and the discharge mechanism 30 are connected, and the conveying mechanism 10 conveys the processed wheel hub to the discharge mechanism 30, and then the discharge mechanism 30 delivers the processed wheel hub.

[0030] A driving mechanism 22 is provided in the middle of the upper part of the processing table 14. The driving mechanism 22 is connected to two movable blocks 23. The two movable blocks 23 are symmetrically arranged relative to the driving mechanism 22. A lifting cylinder is provided on the movable block 23. The lifting cylinder is connected to a rotating motor. The rotating motor is connected to a clamping block 21. The clamping block 21 is driven to rotate by the rotating motor so that a part of the clamping block 21 is located above the wheel hub. The clamping block 21 is then driven to descend by the lifting cylinder so that the clamping block 21 is pressed on the wheel hub, thereby clamping the wheel hub.

[0031] The driving mechanism 22 drives the movable block 23 to move, and can adjust the distance between the two clamping blocks 21, so as to effectively clamp the wheel hubs with different diameters.

[0032] A rubber block is arranged at the bottom of the clamping block 21, and the rubber block can prevent the clamping block 21 from directly contacting the wheel hub, protect the wheel hub, and prevent the wheel hub from being scratched or crushed. A fixed backer 20 is arranged on each of the left and right sides of the driving mechanism 22, and the fixed backer 20 is used to support the wheel hub. The positioning mechanism 15 includes a support frame 17, and a lifting mechanism 18 is arranged on the upper part of the support frame 17. The lifting mechanism 18 is driven and connected to a positioning rod 19. The positioning rod 19 includes an introduction head, a reducing section, and a positioning section arranged in sequence from bottom to top. The introduction head is hemispherical, and the reducing section is a truncated cone structure with a lower end diameter smaller than the upper end diameter. The diameter of the lower end of the reducing section is the same as the diameter of the introduction head, and the diameter of the upper end of the radius section is the same as the diameter of the positioning section. The diameter of the positioning section is set according to the shaft hole of the wheel hub, and is generally designed to be 0.5-1mm smaller than the diameter of the shaft hole of the wheel hub.

[0033] The setting of the guide head facilitates the insertion of the positioning rod 19 into the shaft hole of the wheel hub. The design of the reducing section is used for the positioning rod 19 to adjust the position of the wheel hub by contacting the inner wall of the shaft hole, centering the wheel hub, so that the wheel hub is placed accurately and the subsequent drilling operation can be completed accurately.

[0034] A guide rail 33 is arranged on the side of the support seat 6 where the clamping mechanism 8 is installed. A limit block 34 is slidably arranged on the guide rail 33. The limit block 34 is connected to the clamping mechanism 8, and the lifting mechanism 7 is drivingly connected to the limit block 34.

[0035] The clamping mechanism 8 includes a transverse plate 24, and a telescopic mechanism 25 is arranged on the outer side of the transverse plate 24. The telescopic mechanism 25 includes driving ends respectively located on the left and right sides, and a moving block 26 is connected to the driving end. Two clamping rollers 28 are arranged on the inner side of the moving block 26. The inner side of the moving block 26 is connected to a mounting plate 27 located above and below the clamping roller 28, and the clamping roller 28 is rotatably arranged between the two mounting plates 27.

[0036] A plurality of grooves 29 are formed on the outer periphery of the clamping roller 28. The grooves 29 are arranged along the axial direction of the clamping roller 28. The arrangement of the grooves 29 increases the friction between the clamping roller 28 and the wheel hub, so that the clamping roller 28 can clamp the wheel hub more firmly.

[0037] Two limit mechanisms 11 are respectively arranged on the left and right sides of the conveying mechanism 10. The limit mechanisms 11 are located between the two conveying rollers 32 of the conveying mechanism 10. The limit mechanisms 11 include a hydraulic cylinder 36. The hydraulic cylinder 36 is connected to a support block 37. A support rod 38 is connected to the upper part of the support block 37. The support rod 38 is perpendicular to the support block 37. A limit wheel 39 is rotatably arranged on the support rod 38. After the processed wheel hub is placed on the conveying mechanism 10, the hydraulic cylinder 36 controls the extension of its piston rod, thereby driving the limit wheel 39 to approach the wheel hub. The four limit wheels 39 are pressed against the outer periphery of the wheel hub to fix the wheel hub, thereby preventing the wheel hub from sliding during the lifting and lowering process of the conveying mechanism 10.

[0038] A mounting block 41 is provided in the middle of the driving mechanism 22, and a detection mechanism 40 is installed on the mounting block 41. A mounting cavity 42 is provided inside the mounting block 41, a guide seat 43 is provided at the bottom of the mounting cavity 42, a through hole 44 is provided at the middle of the upper part of the mounting block 41, and the detection mechanism 40 includes a moving sleeve 45 slidably provided in the through hole 44, and the bottom of the moving sleeve 45 is located in the guide seat 43. A retaining ring 46 is connected to the portion of the outer periphery of the moving sleeve 45 located in the mounting cavity 42, and a spring 47 is connected between the retaining ring 46 and the guide seat 43. A trigger block 48 is provided at the portion of the bottom of the mounting cavity 42 located in the guide seat 43, and the trigger block 48 is located below the moving sleeve 45. The movable sleeve 45 is hollow, and the top of the inner circumference of the movable sleeve 45 is connected to a limiting ring 49, and a lifting block 50 is slidably arranged inside the movable sleeve 45. The diameter of the lifting block 50 is larger than the inner diameter of the limiting ring 49 and smaller than the inner diameter of the movable sleeve 45. A protrusion 53 is connected to the upper part of the lifting block 50, and the protrusion 53 is located in the limiting ring 49. A spring 2 51 is connected to the lower part of the lifting block 50, and the lower end of the spring 2 51 is connected to the bottom of the installation cavity 42. A trigger block 2 52 is arranged at the bottom of the installation cavity 42 below the lifting block 50.

[0039] When the wheel hub is placed on the processing table 14, the wheel hub is supported by the fixed backrest 20. The drum of the wheel hub will press on the limit ring 49. The limit ring 49 will drive the lifting block 50 to descend together, and the bottom of the limit ring 49 will contact the trigger block 1 48. The trigger block 1 48 sends a signal to the lifting cylinder and the rotating motor of the control clamp block 21, so that the lifting cylinder and the rotating motor start the control clamp block 21 to rotate and descend, and clamp the wheel hub. The processing table 14 then moves the wheel hub to the bottom of the positioning mechanism 15 for positioning. The clamp block 21 releases the wheel hub, and the lifting mechanism 18 controls the positioning rod 19 to descend, so that the positioning rod 19 is inserted into the axial hole of the wheel hub, and the wheel hub is centered by the positioning rod 19. During the process of the positioning rod 19 descending, it abuts against the upper end surface of the protrusion 53. The positioning rod 19 drives the lifting block 50 to descend through the protrusion 53. When the positioning section of the positioning rod 19 is inserted into the shaft hole of the wheel hub, the lifting block 50 contacts the trigger block 2 52. The trigger block 2 52 sends a signal to the lifting cylinder and the rotating motor of the control clamp block 21, so that the clamp block 21 clamps and fixes the positioned wheel hub. This is to prepare for the subsequent drilling of the wheel hub by the drilling mechanism 16.
