Detailed Implementation

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] Please see Figures 1-4 This utility model provides a pressing device for screw fastener production, including a housing 1. Two limiting rods 2 are provided at both the upper and lower ends of the housing 1. Each of the upper and lower ends of the housing 1 has a rotating groove 3, located between the two limiting rods 2. A threaded sleeve 4 is rotatably disposed within each of the two rotating grooves 3. A first pulley 5 is provided at one end of the threaded sleeve 4. A screw 6 is threaded into the threaded sleeve 4. A retaining seat 7 is provided at one end of the screw 6, and a limiting plate 8 is provided at the other end of the screw 6. Two support seats 9 are provided at the rear end face of the housing 1. A connecting rod 10 is rotatably disposed on each support seat 9. A second pulley 11 is provided at one end of the connecting rod 10, and the first pulley 5 and the second pulley 11... The pulley 11 is connected via the belt body 12. The limiting plate 8 is slidably connected to the corresponding limiting rod 2 and is sleeved on the two limiting rods 2. The clamping seat 7 is set at the upper and lower ends of the fastener, and the clamping seat 7 is directly driven by the threaded sleeve 4 and the screw 6. It should be noted that the two connecting rods 10 in this design are driven by a dual-axis motor 23. Under the action of the first pulley 5, the second pulley 11 and the belt body 12, the threaded sleeve 4 rotates. With the cooperation of the threaded sleeve 4 and the screw 6, the fastener can avoid poor clamping effect. This design effectively improves clamping stability, enhances fastening effect, reduces maintenance costs, and improves safety and reliability.

[0020] The inner side of the clamping seat 7 is provided with a support pad 13, and the front end face of the clamping seat 7 is provided with a baffle 14, which covers the support pad 13. The support pad 13 can increase the friction between the clamping seat 7 and the screw fastener 25, improve the clamping stability, and can also adapt to screw fasteners 25 of different shapes. The baffle 14 can prevent the screw fastener 25 from sliding out of the clamping seat 7 during the pressing process, further enhancing the safety of the pressing device.

[0021] Secondly, two abutment rings 15 are provided on the outer side of the threaded sleeve 4, and the two abutment rings 15 abut against the inner and outer end faces of the housing 1 respectively. The abutment rings 15 can ensure the stable rotation of the threaded sleeve 4 in the rotating groove 3, and at the same time prevent the threaded sleeve 4 from detaching from the housing 1 during rotation.

[0022] Furthermore, the pressing device for producing screw fasteners 25 also includes a closed door 16 and a baffle plate 17. The end face of the closed door 16 has a through hole 18. The closed door 16 is hinged to the housing 1 and located on the front end face of the housing 1. The baffle plate 17 is fixedly connected to the housing 1 and located on the front end face of the housing 1, and is also located within the through hole 18. The closed door 16 can protect the internal structure of the pressing device and prevent more dust and debris from entering. The baffle plate 17 can further increase the safety of the pressing device and prevent operators from accidentally contacting rotating parts during the pressing process.

[0023] In addition, the pressing device for producing screw fasteners 25 also includes a support plate 19 and a bracket 20. The end face of the support plate 19 is provided with a buffer pad 21. Both sides of the housing 1 have sliding grooves 22. The support plate 19 is slidably connected to the housing 1 and located inside the housing 1. The bracket 20 is fixedly connected to the housing 1 and located below the housing 1. In this design, the support plate 19 is pushed by two electric push rods 24. With the cooperation of the electric push rods 24, the support plate 19 can further fix and press the screw fasteners 25, so that the pressing device can more stably clamp the screw fasteners 25 during the pressing process, preventing them from loosening or falling off. At the same time, the buffer pad 21 can reduce the impact on the screw fasteners 25 during the pressing process and protect them from damage.

[0024] When using this utility model, the screw fastener 25 is placed between the two clamping seats 7, and then the dual-axis motor 23 is started, so that the two output ends of the dual-axis motor 23 drive the corresponding connecting rods 10 clockwise. The threaded sleeve 4 rotates under the action of the first pulley 5, the second pulley 11 and the belt body 12, and the screw 6 pushes the clamping seat 7 to clamp the screw fastener 25 under the action of the limiting rod 2 and the limiting plate 8. Then, the screw fastener 25 is clamped under the action of the supporting pad 13. Then, the two electric push rods 24 are started, so that the supporting plate 19 moves towards the screw fastener 25, so that the buffer pad 21 presses the screw fastener 25. At this time, the screw fastener 25 can be processed.

[0025] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
