Description

Technical Field

[0002] Crimping machines are essential tools for the power industry to crimp conductors during line infrastructure construction and maintenance. Crimping machines are categorized into hydraulic crimping machines, large-tonnage crimping machines (punch presses), insulated terminal crimping machines, split-type crimping pliers, and hand-cranked hydraulic crimping machines. Currently, cable stripping and terminal crimping in the wind power industry are mostly semi-automated. Most commercially available equipment is unsuitable for processing cables for the wind power industry, requiring manual processing. This involves conveying, stripping, and crimping cables, requiring numerous human resources to coordinate and operate. This wastes significant human resources and reduces processing efficiency. Furthermore, existing terminal crimping machines offer suboptimal crimping results for large-square terminals, requiring frequent die changes during the crimping process. Furthermore, the crimped terminals cannot be crimped into the regular hexagonal shape required for large-square cables, resulting in poor crimping results.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0039] The cable unloading mechanism 2, the terminal crimping mechanism 3, the terminal conveying mechanism 4, the cable stripping mechanism 5 and the cable conveying mechanism 7 are sequentially installed on the fixed base 1;

[0040] The cable unloading mechanism 2 and the cable conveying mechanism 7 are both used to convey cables, the cable stripping mechanism 5 is used to strip and cut cables, the terminal conveying mechanism 4 is used to sleeve cylindrical terminals on the stripped cable ends, and the terminal crimping mechanism 3 is used to crimp cylindrical terminals into hexagons.

[0041] In the present invention, the cable is loaded through the cable conveying mechanism 7, the cable stripping mechanism 5 strips and cuts the cable, the terminal crimping mechanism 3 performs crimping, and the cable unloading mechanism 2 completes unloading, thereby realizing a fully automatic crimping process for wind power cables. This process is suitable for automated production scenarios, and the terminal of a hollow cylinder can be crimped into a regular hexagon, which can adapt to the terminal installation requirements of wind power cable applications. The present invention integrates multiple mechanisms and control systems to realize the automated production of the entire process of automatic loading, stripping, cutting, terminal sleeve connection, crimping, and unloading of cables. The present invention has the advantages of high precision, high efficiency, high stability, and low energy consumption, and is suitable for large-scale automated production scenarios, which can significantly improve production efficiency and reduce production costs.

[0042] Furthermore, the terminal crimping mechanism 3 includes a bracket 302, a sliding seat 301, a base 303 and a crimping module;

[0043] The sliding seat 301 is slidably arranged on the bracket 302, and the base 303 is fixedly arranged below the sliding seat 301. The crimping modules are arranged on the opposite side of the base 303 and the sliding seat 301, and a hexagonal hollow part is formed between the two crimping modules for crimping the cylindrical terminal into a hexagon.

[0044] The two crimping modules are symmetrically arranged, and the cable and its terminal are located in the hexagonal hollow part during crimping. During the relative movement of the two crimping modules, the cylindrical terminal is crimped into a hexagonal shape.

[0045] Furthermore, the crimping module includes a first bevel block 305, a second bevel block 306 and a third bevel block 307, one end of the first bevel block 305 is fixedly connected to the middle of the second bevel block 306, one end of the second bevel block 306 is fixedly connected to the middle of the third bevel block 307, and the three bevel blocks are all arranged at an angle, and the inner sides of the three bevel blocks jointly form a notch portion, and the notch portion is trapezoidal. The notch portions of the two crimping modules jointly form a hexagonal hollow portion.

[0046] The inner sides of the three oblique blocks form planes with an angle of 120° to each other, so the notches of the two crimping modules together form two parts of a regular hexagon.

[0047] Furthermore, a groove is provided on one side of the base 303 and the sliding seat 301, and the two crimping modules are respectively provided in the groove;

[0048] One end of the first oblique block 305 away from the second oblique block 306 is rotatably connected to the inner wall of the slot body, one end of the second oblique block 306 away from the third oblique block 307 is fixedly connected to the first spring 310, the first spring 310 is fixedly connected to the first fixed block 311, the first fixed block 311 is fixedly connected to the inner wall of the slot body, the end of the third oblique block 307 is fixedly connected to the second spring 308, the second spring 308 is fixedly connected to the second fixed block 309, and the second fixed block 309 is fixedly connected to the inner wall of the slot body.

[0049] Specifically, the third bevel 307 is spaced apart from the open end of the slot body on one side away from the second bevel 306. During crimping, after the inner sides of the three bevels contact the terminal, the first and second springs are squeezed, and the first bevel 305 rotates slightly. The sliding seat 301 then continues to move downward until the terminal is crimped into a hexagon. The first bevel 305 enables the crimping module to rotate slightly when contacting the terminal, while the first and second springs are used to achieve a reset function. Therefore, during crimping, the rotation of the crimping module can reduce the matching accuracy requirements, and due to the elastic action of the first and second springs, the two crimping modules can adapt to terminals of different diameters, so as to adapt to the crimping of terminals of different sizes.

The top of the claw 21 is rotatably connected to the claw seat 16, and multiple claws 21 are arranged around the piston rod.

[0055] Linear cylinders are conventional, such as hydraulic, pneumatic, and electric cylinders. The top of the claw 21 connects to the main connecting rod 19 and the secondary connecting rod 20. Pins connect the ends of the main and secondary connecting rods 19 and 20 to the claw base 16 and claw 21. The connecting rod 18 rotatably connects to the side of the main connecting rod 19. When the piston rod moves, the power rod 17 moves in the same direction, driving the claw 21 to grip the cable terminal. The claw base 16 can rotate 360 ​​degrees to install the gripped terminal onto the stripped cable.

[0056] In addition, a terminal storage compartment may be provided on the fixed base 1 , which stores a plurality of terminals and is taken out in sequence.

[0057] The manipulator is based on existing technology and may also adopt the following structure: the chassis 9 is fixed on the base 10, the base 10 and the upper arm 11 are directly connected by bolts, and the two are directly controlled by the cylinder 22 and the piston rod 23 to control the movement of the upper arm 11, the upper arm 11 and the arm 14 are controlled by the first cylinder 12 and the first piston rod 13 to control the movement of the arm 14, the arm 14 is connected to the second cylinder 15 and the claw seat 16, the output end of the second cylinder 15 is connected to the piston rod, and the end of the arm 14 is connected to the claw seat 16.

[0058] Furthermore, the cable stripping mechanism 5 includes a gear 24, a first rack 25, a second rack 26, an upper ring cutter 27, an upper fixing member 28, a lower ring cutter 29 and a lower fixing member 30;

[0059] The two sides of the gear 24 are respectively engaged with the first rack 25 and the second rack 26. The first and second racks are both vertically arranged. The first rack 25 is fixedly connected to the upper ring cutter 27 through the upper fixing member 28, and the second rack 26 is fixedly connected to the lower ring cutter 29 through the lower fixing member 30.
