Detailed implementation manner

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0025] As Figures 1-3 shown, a rolling thread automatic positioning tooling for fasteners includes a mounting plate 1. A first mounting frame 2 is fixedly arranged on the upper surface of the mounting plate 1, and first card slots 3 are respectively arranged on the inner sides of the first mounting frame 2. A bracket 4 is slidably arranged on the outer surface of the first mounting frame 2. Telescopic rods 5 are fixedly arranged on both sides inside the bracket 4. A first spring 6 is arranged around the telescopic rods 5. A first pin 7 is fixedly arranged at the outer end of the telescopic rod 5, and the first pin 7 penetrates through the bracket 4. The lower side of the first pin 7 is provided with an inclined surface. An inner threaded rod 8 is fixedly arranged at the upper end of the bracket 4, and the inner threaded rod 8 penetrates through the bracket 4. A screw 9 is meshed inside the inner threaded rod 8, and clamping blocks 10 are fixedly arranged on the lower end of the screw 9 and the upper surface of the mounting plate 1 respectively. When replacing the fasteners to be processed, the first pin 7 can be directly unlocked and then the bracket 4 can be directly lifted upwards, so as to more quickly unload the processed fasteners, thereby improving the work efficiency. During installation, first slide the bracket 4 downwards and lock it, and then rotate the screw 9 to make the clamping block 10 move downwards, thereby locking the fastener. In this way, the fastener can be quickly fixed without excessive rotation, further improving the work efficiency.

[0026] Further, the lower side of the first pin 7 is provided with an inclined surface to make the downward movement of the bracket 4 faster and more convenient. Because of the inclined surface, it can directly contract inwards when moving downwards.

[0027] Further, through the movement of the bracket 4, when replacing workpieces with large size changes, it is not necessary to rotate the screw 9 too much. After the bracket 4 moves to a suitable position, then rotate the screw 9. At this time, only a small distance needs to be rotated to fix the workpiece.

[0028] As Figures 4-6As shown in the figure, a connecting rod 11 is slidably arranged on one side of the mounting plate 1, and the connecting rod 11 penetrates through the mounting plate 1. One end of the connecting rod 11 located inside the mounting plate 1 is fixedly provided with a first top block 13, and the first top block 13 is trapezoidal. A second spring 12 is fixedly arranged around the connecting rod 11 between the mounting plate 1 and the first top block 13. Both sides of the first top block 13 are slidably provided with second top blocks 14, and the second top blocks 14 are trapezoidal. On the outer sides of the second top blocks 14, second pins 15 are fixedly arranged, and the second pins 15 penetrate through the side surface of the mounting plate 1. A third spring 16 is arranged around the second pins 15, and the third spring 16 is fixedly connected to the second top blocks 14 and the inner surface of the mounting plate 1 respectively. After the clamping is estimated to be completed, the mounting plate 1 is pushed forward to a suitable position and fixed by the second pins 15. After the processing is completed, the connecting rod 11 can be pulled to make the first top block 13 away from the second top block 14, thereby releasing the third spring 16. At this time, the third spring 16 can retract the second pins 15 inward, thereby pulling the mounting plate 1 backward, so that the worker's hands can be kept away from the processing equipment and the worker's hands can be prevented from being injured; a base 17 is arranged below the mounting plate 1, and a chute 18 is opened at the upper end of the base 17. The chute 18 is slidably connected to the mounting plate 1. Clamping grooves 19 are opened on both sides of the chute 18. One end of the base 17 is fixedly provided with a second mounting bracket 20, and threaded holes 21 are opened around the second mounting bracket 20, and the threaded holes 21 penetrate through the second mounting bracket 20. The threaded holes 21 are evenly distributed around the center of the circle. A bolt 22 is arranged inside the threaded holes 21, and a roller 23 is rotatably arranged at one end of the bolt 22 located inside the second mounting bracket 20. When the mounting plate 1 moves to a suitable position, the fastener will pass through the middle of the second mounting bracket 20 and be positioned again by the roller 23, which can further reduce the defective rate of the product and the production cost, and the position of the roller 23 can be changed by rotating the bolt 22 according to different processing requirements, so that the device can adapt to more different processing requirements and workpieces of different shapes.

[0029] Further, the first top block 13 presses against the second top blocks 14 under the action of the second spring 12, thereby pushing the second top blocks 14 outwards on both sides, and further pushing the second pins 15 outwards on both sides, so that the mounting plate 1 can be fixed.

[0030] Working principle: When using this automatic positioning tooling for thread rolling of fasteners, first, when replacing the processed fasteners, the pin 7 can be directly unlocked, and then the bracket 4 can be lifted upward directly to facilitate the faster removal of the processed fasteners, thus improving work efficiency. During installation, first slide the bracket 4 downward and lock it, and then rotate the screw rod 9 to make the clamping block 10 move downward, thereby locking the fastener. In this way, the fastener can be fixed quickly without excessive rotation, further improving work efficiency. Secondly, after the fastener is clamped, push the mounting plate 1 forward to a suitable position and fix it with the pin 2. After processing is completed, pull the connecting rod 11 to make the first top block 13 move away from the second top block 14, thereby releasing the third spring 16. At this time, the third spring 16 can retract the pin 2 inward, thereby pulling the mounting plate 1 backward. This can keep the worker's hands away from the processing equipment and prevent the worker's hands from being injured. Finally, when the mounting plate 1 moves to a suitable position, the fastener will pass through the middle of the mounting bracket 20, and it is positioned again by the roller 23. This can further reduce the defective rate of the product, reduce production costs, and according to different processing requirements, the position of the roller 23 can be changed by rotating the bolt 22, so that the device can adapt to more different processing requirements and workpieces with different shapes. This is the working principle of this automatic positioning tooling for thread rolling of fasteners.
