Any features such as component models, material names, connection structures, control methods, algorithms, etc. not explicitly described in this technical solution are considered to be common technical features disclosed in the prior art.
[0033] Example 1
[0034] The metal wire clamping device in this embodiment includes a housing 1, a fixed clamping block 4, a first movable clamping block 5, a first electric cylinder 6, a second movable clamping block 7, a third movable clamping block 9, and a second electric cylinder 10. Figure 1 .
[0035] The housing 1 has a central channel 2 for routing wires, through which a metal wire 3 is threaded. A fixed clamping block 4 is located on a first side of the housing 1. A first dynamic clamping block 5 is located on a second side of the housing 1, facing the fixed clamping block 4. The output end of a first electric cylinder 6 is connected to the first dynamic clamping block 5, driving the first dynamic clamping block 5 to engage with the fixed clamping block 4 to tighten and loosen the metal wire 3.
[0036] The second dynamic clamping block 7 is connected to the first side of the housing 1 through a second spring 8 ; the third dynamic clamping block 9 is arranged on the second side of the housing 1 , and the third dynamic clamping block 9 is arranged opposite to the second dynamic clamping block 7 .
[0037] The output end of the second electric cylinder 10 is connected to the third dynamic clamping block 9 , and can drive the third dynamic clamping block 9 to cooperate with the second dynamic clamping block 7 to achieve the clamping and loosening of the metal wire 3 .
[0038] The first dynamic clamping block 5 is connected to the second side of the housing 1 via a first spring 11. A first sliding slot 12 is defined in the first dynamic clamping block 5. A first limiting rod 13 is provided on the third dynamic clamping block 9. One end of the first limiting rod 13 is connected to the third dynamic clamping block 9, and the other end is positioned in the first sliding slot 12. The movable travel distance of the first limiting rod 13 in the first sliding slot 12 is greater than the outer diameter of the first limiting rod 13.
[0039] A second sliding groove 14 is provided in the second movable clamping block 7. A second limiting rod 15 is provided on the fixed clamping block 4. One end of the second limiting rod 15 is connected to the fixed clamping block 4, and the other end of the second limiting rod 15 is positioned in the second sliding groove 14. The movable travel distance of the second limiting rod 15 in the second sliding groove 14 is greater than the outer diameter of the second limiting rod 15.
[0040] The output shaft of the first electric cylinder 6 passes through the middle of the first spring 11 and is connected to the first dynamic clamping block 5 .
[0041] The ends of the fixed clamping block 4 , the first movable clamping block 5 , the second movable clamping block 7 and the third movable clamping block 9 that are in contact with the metal wire 3 are all provided with a rubber layer.
[0042] The working principle of the metal wire clamping device of the utility model is as follows:
[0043] First, the metal wire 3 is passed through the hole 2 in the middle of the housing 1. When the metal wire 3 needs to be clamped, the first electric cylinder 6 is started, and its output end pushes the first movable clamping block 5 to move toward the fixed clamping block 4. During this process, the first movable clamping block 5 is connected to the second side of the housing 1 through the first spring 11. The elasticity of the first spring 11 acts as a buffer to prevent the first movable clamping block 5 from violently colliding with the fixed clamping block 4. At the same time, a first sliding groove 12 is provided in the first movable clamping block 5. One end of the first limiting rod 13 on the third movable clamping block 9 is connected to the third movable clamping block 9, and the other end is placed in the first sliding groove 12. The first limiting rod 13 slides in the first sliding groove 12 to provide guidance and limitation for the movement of the first movable clamping block 5, ensuring that it accurately approaches the fixed clamping block 4 until the first movable clamping block 5 cooperates with the fixed clamping block 4 to achieve preliminary clamping of the metal wire 3.
[0044] At the same time, the second electric cylinder 10 also begins to operate, its output end pushing the third movable clamping block 9 toward the second movable clamping block 7. The second movable clamping block 7 is connected to the first side of the housing 1 via a second spring 8, which also utilizes the spring's elasticity to achieve cushioning. A second sliding groove 14 is provided in the second movable clamping block 7. A second limiting rod 15 on the fixed clamping block 4 has one end connected to the fixed clamping block 4 and the other end positioned in the second sliding groove 14. The second limiting rod 15 slides within the second sliding groove 14, ensuring that the third movable clamping block 9 can accurately move toward and engage with the second movable clamping block 7.
[0045] Ultimately, through the cooperation between the first dynamic clamping block 5 and the fixed clamping block 4, as well as the second dynamic clamping block 7 and the third dynamic clamping block 9, a stable and reliable clamping of the metal wire 3 is achieved. Furthermore, the end of each clamping block that contacts the metal wire 3 is provided with a rubber layer, which increases friction to ensure a secure clamping while also preventing damage to the wire surface.
[0046] The above description of the embodiments is intended to facilitate understanding and use of the utility model by those skilled in the art. Those skilled in the art will readily be able to make various modifications to these embodiments and apply the general principles described herein to other embodiments without requiring inventive effort. Therefore, the utility model is not limited to the above-described embodiments. Improvements and modifications made by those skilled in the art based on the disclosure of this utility model without departing from the scope of this utility model should be within the scope of protection of this utility model.
