Description

Technical Field

[0001] This utility model relates to the field of cable chain component equipment technology, and more specifically, to an adjustable cable chain clamp. Background Technology

[0002] Cable chains are generally divided into two types: steel cable chains and plastic cable chains. They are widely used in production. Steel cable chains are also called steel-aluminum cable chains, while plastic cable chains are also called engineering nylon cable chains, tank chains, or engineering plastic cable chains. Based on the usage environment and requirements, they are classified as bridge-type cable chains, fully enclosed cable chains, and semi-enclosed cable chains. Cable chains can coordinate with the moving parts of machine tools and mechanical equipment, providing safety protection and guidance. They can extend the service life of protected cables, oil pipes, and air pipes, reduce consumption, and significantly improve the neat and orderly arrangement of cables, oil pipes, and air pipes in machine tools and mechanical equipment, enhancing the overall aesthetic appearance of the equipment. They are suitable for use in CNC machine tools, machining centers, automated machinery and production lines, as well as various machine tools, robots, transportation machinery, measuring instruments, handling devices, and other drive control systems, serving as protective devices for cables, air pipes, oil pipes, and water pipes.

[0003] Currently, cable carriers mostly use dividers to separate cables bundled in different ways. This type of divider structure has the following problems: First, it cannot be adjusted according to the diameter of different cables, and the gap is too large, resulting in poor cable guidance and excessive bending between the horizontal and vertical dividers inside the cable carrier. Second, after long-term use, the horizontal and vertical dividers are prone to relative displacement, resulting in poor stability. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable cable clamp for cable chains. This cable clamp structure can adjust the spacing between the clamp plates, making it suitable for guiding cables of different diameters and reducing excessive bending of the cables. At the same time, it can limit the horizontal and vertical separators, improving the stability of the cable chain during long-term use.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An adjustable cable clamp for a cable chain includes cable chain units, wherein several cable chain units are connected end to end to form a complete cable chain body. A rotating upper cover plate is provided at the upper end of each cable chain unit, and a fixed lower cover plate is provided at the lower end of each cable chain unit. Several vertical and horizontal partition plates are embedded between the rotating upper and lower cover plates. The upper and lower ends of the vertical partition plates are fastened to the sides of the rotating upper and lower cover plates by snap-fit ​​fasteners. Base plates are provided on the front and rear sides at the junction of the vertical and horizontal partition plates. Through holes are machined on the upper end of one side and the lower end of the other side of each base plate, and connecting screws pass through the through holes. The connecting screws are tightened by nuts at both ends to secure the front and rear base plates against the front and rear sides of the vertical partition plates, respectively. The shaft of the connecting screw is inwardly positioned at the upper end of one side and the lower end of the other side of the horizontal partition plate.

[0007] As a further optimization of this solution, an installation plate is welded and fixed outward at the middle position of the outer side of the base plate. Parallel adjusting screws are connected to the upper and lower sides of the installation plate, and several cable clamps at different height positions are installed on the rod of the adjusting screws by means of nuts. The cable passing through the drag chain is clamped between adjacent cable clamps.

[0008] As a further optimization of this solution, the cross-section of the cable clamp is elliptical.

[0009] As a further optimization of this solution, the base plate is staggered vertically within the drag chain area formed by the vertical and horizontal partitions.

[0010] As a further optimization of this solution, the spacing between adjacent cable clamps corresponds to the diameter of the cable passing through.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0012] This invention firstly, by designing a base clamping plate and connecting screw structure, effectively limits the vertical and horizontal partitions inside the cable chain unit, reducing the relative displacement of the vertical and horizontal partitions after prolonged use and improving the overall stability of the cable chain unit. Simultaneously, by designing an mounting plate, adjusting screws, and cable clamping strips, it can adapt to cables of different diameters. By changing the spacing between adjacent cable clamps with nuts, cables passing through the vertical and horizontal partitions are clamped from the front and rear sides, achieving cable guidance and preventing excessive bending of the cables between the vertical and horizontal partitions.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0018] To address the issues that the existing separation structure cannot be adjusted according to the diameter of different cables, has a large gap distance, resulting in poor cable guidance, excessive bending between the horizontal and vertical separators inside the cable chain, and relative displacement and instability between the horizontal and vertical separators after long-term use.

[0019] like Figure 1 As shown, this application includes a cable chain unit 1, wherein several cable chain units 1 are connected end to end to form a cable chain body. A rotating upper cover plate 2 is provided at the upper end between the cable chain units 1 and a fixed lower cover plate 3 is provided at the lower end between the cable chain units 1. Several vertical partition plates 4 and horizontal partition plates 5 are embedded and installed between the rotating upper cover plate 2 and the lower cover plate 3. The upper and lower ends of the vertical partition plates 4 are fastened and fixed to the sides of the rotating upper cover plate 2 and the lower cover plate 3 by buckles.

[0020] like Figure 2 As shown, base plates 7 are provided on both the front and rear sides at the junction of the vertical partition 4 and the horizontal partition 5. The upper end of one side and the lower end of the other side of the surface of the base plate 7 are machined with through holes, and the connecting screw 11 passes through the through holes. The connecting screw 11 is tightened and fixed by the nuts 10 at both ends to fit the front and rear base plates 7 tightly against the front and rear sides of the vertical partition 4 respectively. The rod of the connecting screw 11 is inwardly limited to the upper end of one side and the lower end of the other side of the horizontal partition 5.

[0021] like Figure 3As shown, an installation plate 8 is welded and fixed outward at the middle position of the outer side of the base plate 7. Parallel adjusting screws 9 are connected to the upper and lower sides of the installation plate 8. Several cable clamps 6 at different heights are installed on the rod of the adjusting screw 9 by means of nuts 10. The cable passing through the cable chain is clamped between adjacent cable clamps 6. The cross-section of the cable clamp 6 is elliptical. The base plate 7 is staggered in the vertical and horizontal partitions 5 within the cable chain area. The spacing between adjacent cable clamps 6 corresponds to the diameter of the cable passing through.

[0022] Specifically, the base plate 7 and the connecting screw 11 effectively limit the front-to-back and up-to-down positions of the vertical partition plate 4 and the horizontal partition plate 5 inside the cable chain unit 1, respectively, reducing the relative displacement of the vertical partition plate 4 and the horizontal partition plate 5 after long-term use and improving the overall stability of the cable chain unit 1. At the same time, the mounting plate 8 connects to the structure of the up-and-down adjusting screw 9, which facilitates the adjustment of the height of the cable clamp 6 using the nut 10. It can be adapted to cables of different diameters. By changing the spacing between adjacent cable clamps 6 with the nut 10, the cable passing through the vertical partition plate 4 and the horizontal partition plate 5 is clamped from the front and back sides, realizing the guidance of the cable and avoiding the problem of excessive bending of the cable between the vertical partition plate 4 and the horizontal partition plate 5. The use of an elliptical surface can reduce the friction loss between the cable clamp 6 and the cable, further improving the cable life.
