[0031] Reference Figure 1-6 ,

[0032] An automatic feeding mechanism for thread rolling of a ball pin 1, wherein a head 11 and a tail 12 are formed on the ball pin 1, a convex portion 13 is formed at the connection between the head 11 and the tail 12, and a thread rolling wheel 21 and a driven wheel 22 are formed on a thread rolling machine 2. A driving device is provided inside the thread rolling machine 2 for the thread rolling wheel 21 to approach or move away from the driven wheel 22, and the thread rolling wheel 21 can rotate around a fixed axis direction. After approaching the driven wheel 22, the thread rolling wheel 21 can clamp the tail 12 of the ball pin 1 and roll the thread of the tail 12 of the ball pin 1 through its own rotation. The feeding mechanism includes: a supporting structure 3 and a conveying structure 4. The supporting structure 3 is used to form a first abutment member 31 abutting against the tail 12 of the ball pin 1 and a second abutment member 32 abutting against the convex portion 13 of the ball pin 1 at a processing position. The first abutment member 31 is a block structure, and the second abutment member 32 is a plate structure. The first abutment 31 is located below the abutment between the thread rolling wheel 21 and the driven wheel 22, and the thread rolling wheel 21 will not interfere with the first abutment 31 when it approaches the driven wheel 22. The second abutment 32 is installed on the thread rolling machine 2. The conveying structure 4 is used to convey the ball pin 1 to the processing position. The processing position is located at the abutment between the thread rolling wheel 21 and the driven wheel 22. Among them, when the conveying structure 4 conveys the ball pin 1 to the processing position, the second abutment 32 abuts against the convex part 13 of the ball pin 1 to stop the ball pin 1 at the processing position. In the process of conveying the ball pin 1 by the conveying structure 4, the thread rolling wheel 21 gradually approaches the driven wheel 22, and when the ball pin 1 stops at the processing position, the thread rolling wheel 21 and the driven wheel 22 just clamp the tail 12 of the ball pin 1, and at this time, the thread rolling wheel 21 rolls the ball pin 1. A conveying track is also provided below the processing position, and the ball pin 1 after thread rolling can be output along the conveying track. The first abutment 31 is used to support the ball pin 1 along the first direction 312 to prevent the ball pin 1 from deviating downward or falling during the thread rolling process. The second abutment 32 is used to limit the ball pin 1 along the second direction 322 to ensure that the thread rolling wheel 21 can clamp the tail 12 of the ball pin 1 after approaching the driven wheel 22, so that when the thread rolling wheel 21 drives the ball pin 1 to rotate, the length of the tail 12 between the thread rolling wheel 21 and the driven wheel 22 remains unchanged. The first abutment 31 and the second abutment 32 are both detachably connected to the thread rolling machine 2. This arrangement makes it easy for the staff to adjust the thread rolling position of the ball pin 1. The first direction 312 is perpendicular to the second direction 322. Since the end face on the tail 12 on the ball pin 1 is perpendicular to a face on the convex portion 13, refer to the accompanying drawings Figure 6 Therefore, in this embodiment, the first direction 312 and the second direction 322 are vertically arranged so that when the ball stud 1 enters the processing position, it can be clamped by the first abutment member 31 and the second abutment member 32.

[0033] Specifically, a first abutting surface 311 is formed on the first abutting member 31 to abut against the tail portion 12. A sliding surface 313 is formed on the first abutting surface 311 at one end close to the conveying structure 4. The sliding surface 313 is provided to protect the ball stud 1 and prevent the ball stud 1 from colliding with the first abutting member 31 when the ball stud 1 moves from the conveying structure 4 to the processing position. A second abutting surface 321 is formed on the second abutting member 32 to abut against the convex portion 13. The second abutting surface 321 is provided perpendicularly to the first abutting surface 311.

[0034] Specifically, the conveying structure 4 includes: a pushing member 41 and a moving member 42. The pushing member 41 is a hydraulic cylinder or a pneumatic cylinder, and in the present embodiment, it is preferably a pneumatic cylinder. The moving member 42 is a block structure. A discharge groove 421 for placing the ball stud 1 is formed on the moving member 42. The pushing member 41 can push the moving member 42 to move along a preset direction so that the moving member 42 can approach or move away from the processing position. The preset direction in the present embodiment is a direction approaching the processing position or moving away from the processing position. When the moving member 42 approaches the processing position, the pushing member 41 can push the ball stud 1 in the discharge groove 421 to the processing position. A first pushing end 411 and a second pushing end 412 are formed on the pushing member 41. The first pushing end 411 is used to push the ball stud 1 to move in the discharge groove 421. The second pushing end 412 is used to push the moving member 42 to move. The first pushing end 411 and the second pushing end 412 are both rod structures. The first pushing end 411 is connected to the output end 413 on the pushing member 41, and the second pushing end 412 is used to push the moving member 42 to the processing position. The first pushing end 411 is used to push the ball pin 1 located in the discharge groove 421 to the processing position. The staff only needs to turn the tail 12 of the ball pin 1 toward the processing position and place the ball pin 1 in the discharge groove 421, which is simple to operate.

[0035] Specifically, the feeding mechanism further comprises: a guide member 5. The guide member 5 is a block structure. A moving member 42 is installed in the guide member 5, and the moving member 42 is slidably connected to the guide member 5.

[0036] Specifically, a limit member 51 is also provided on the guide member 5. The limit member 51 is a plate structure. The limit member 51 is located above the movable member 42 and is arranged parallel to the movable member 42. The limit member 51 is fixed on the guide member 5, and the distance between the limit member 51 and the discharge groove 421 is slightly larger than the diameter of the head 11 of the ball pin 1. When the ball pin 1 moves from the movable member 42 to the processing position, the force of the first pushing end 411 pushing the ball pin 1 to move is too large, which may cause the ball pin 1 to fly out of the discharge groove 421, so the limit member 51 is provided to prevent the ball pin 1 from flying out.

[0037] Specifically, the conveying structure 4 also includes: a movable component 43 and a control component 44. The movable component 43 is a plate structure. The control structure is a hydraulic cylinder or a pneumatic cylinder, and in this embodiment, it is preferably a pneumatic cylinder. A feeding port 431 for placing the ball pin 1 is formed on the movable component 43. The control component 44 is used to drive the movable component 43 to move above the guide member 5 so that the ball pin 1 located in the feeding port 431 enters the discharge trough 421. The feeding mechanism also includes: a feeding component 6. The feeding component 6 is a vibrating disk. A feeding track 61 connected to the feeding port 431 is formed on the feeding component 6 so that the ball pin 1 located in the feeding component 6 can enter the feeding port 431 in sequence.

[0038] Workflow:

[0039] The staff places the ball pin 1 in the feeding member 6, and the ball pin 1 is sequentially transported to the feeding port 431 through the feeding track 61, and then the movable member 43 is driven to move by the control member 44, so that the ball pin 1 located in the feeding port 431 enters the discharge groove 421, and the second pushing end 412 on the pushing member 41 can push the movable member 42 to move toward the processing position, and then the first pushing end 411 pushes the ball pin 1 located in the discharge groove 421 to Processing position, at this time, the tail 12 of the ball pin 1 will abut against the first abutment surface 311, and the convex portion 13 on the ball pin 1 will abut against the second abutment surface 321. In the process of the conveying structure 4 conveying the ball pin 1, the thread rolling wheel 21 gradually approaches the driven wheel 22, and when the ball pin 1 stops at the processing position, the thread rolling wheel 21 and the driven wheel 22 just clamp the tail 12 of the ball pin 1. At this time, the thread rolling wheel 21 rolls the ball pin 1, and the ball pin 1 after thread rolling is output through the output track.
