DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The technical solution of the present utility model will be further described below through embodiments in conjunction with the drawings.

[0017] Embodiment:

[0018] A thread rolling mechanism for a drill tail thread rolling integrated machine in this embodiment, as Figure 1 shown, includes a feeding guide rail 1, a feeding pusher, a thread rolling wheel 9, an arc-shaped thread rolling plate 10, and a discharging guide rail 18 arranged on an inclined platform. The thread rolling wheel 9 is driven by a first motor. A thread rolling channel 17 is formed between the thread rolling wheel 9 and the arc-shaped thread rolling plate 10. The feeding guide rail 1, the thread rolling channel 17, and the discharging guide rail 18 are connected in sequence. The feeding pusher is arranged between the feeding guide rail and the thread rolling channel.

[0019] The feeding push rod includes a first push rod and a second push rod. The first push rod is used to push the screws to be thread-rolled from the outlet of the feeding guide rail 1 to the inlet of the thread-rolling channel 17, and the second push rod is used to push the screws to be thread-rolled from the inlet of the thread-rolling channel 17 into the thread-rolling channel 17. The first push rod includes a push rod motor 2 and a first rod body 3 driven by the push rod motor. The first push rod is placed on the side of the arc-shaped thread-rolling plate, and the side surface of the first rod body 3 is attached to the end surface of the arc-shaped thread-rolling plate. The second push rod includes a torsion spring rotating shaft 4, a cam 6, a second motor, an extension rod 7 and a second rod body 8. A connector 5 is provided on the torsion spring rotating shaft 4, and a abutting column is arranged below the connector 5. The abutting column is always abutted against the cam 6 under the action of the torsion spring rotating shaft. The first end of the extension rod 7 is rotatably arranged on the connector 5, and the second rod body 8 is fixedly arranged at the second end of the extension rod 7. The second push rod is placed on the side of the thread-rolling wheel. The second rod body 8 is arranged close to the thread-rolling wheel and faces the thread-rolling channel. An arc-shaped notch is provided on the side of the second rod body facing the thread-rolling wheel. The setting of the arc-shaped notch can prevent the second rod body from contacting the thread-rolling wheel during movement. In addition, the second push rod can also adopt the same structure as the first push rod.

[0020] A top cover is provided on the thread-rolling wheel. The top cover includes a fixed part 11 and a movable part 12. An arc-shaped groove is provided at the junction of the movable part 12 and the fixed part. An arc-shaped rack 14 is provided in the arc-shaped groove. A groove is provided near the arc-shaped groove in the fixed part, and a gear 15 matching the arc-shaped rack is arranged in the groove. A screwing part is provided on the gear. A first locking pressing block is also provided on the fixed part, and a part of the first locking pressing block is located on the movable part. The first locking pressing block is used to fix and limit the movable part. When the thread-rolling wheel needs to be replaced, first release the fixation and limitation of the movable part by the first locking pressing block, and then put a wrench on the screwing part to screw the gear 15. Under the action of the gear 15, the movable part rotates, which is convenient for disassembling the movable part and thus convenient for replacing the thread-rolling wheel. In addition, the setting of the gear and the arc-shaped rack can also prevent the movable part from shifting when the thread-rolling wheel rotates.

[0021] The arc-shaped thread-rolling plate 10 is fixedly arranged on the seat body 19. The seat body 19 is provided with an installation groove for arranging the arc-shaped thread-rolling plate on the side facing the thread-rolling wheel 9. A plurality of second locking pressing blocks 16 are also provided on the seat body, and a part of the second locking pressing blocks is located on the arc-shaped thread-rolling plate to fix and limit the arc-shaped thread-rolling plate.

[0022] In the thread-rolling mechanism of the drill tail thread-rolling integrated machine in this embodiment, the feeding guide rail receives the screws to be thread-rolled output from the drill tail mechanism. The screws to be thread-rolled slide along the feeding guide to the junction of the feeding guide rail and the thread-rolling channel. Then, the first push rod moves from the upper right to the lower left to push the screws to be thread-rolled to the inlet of the thread-rolling channel. Then, the second push rod pushes from the upper left to the lower right to push the screws to be measured into the thread-rolling channel. Then, under the action of the thread-rolling wheel, the screws to be thread-rolled move along the thread-rolling channel for thread-rolling. After the thread-rolling is completed, the screws slide along the discharging guide rail into the aggregate box.

[0023] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains may make various modifications or supplements to the described specific embodiments or use similar means for substitution, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
