Description

Technical Field

[0001] The utility model relates to the technical field of flexible cables, in particular to a flexible cable winding mechanism. Background Art

[0002] Flexible cables are widely used in industrial automation to connect various sensors, actuators and controllers. Through the coordination of drag chains, flexible cables can meet the flexible movement requirements in complex environments and ensure the stable operation of the system.

[0003] Existing flexible cables that need to be frequently wound up using CNC slide rails cannot be positioned in the drag chain, resulting in frequent contact and friction between the cable sheaths and the inner wall of the drag chain, causing high wear of the flexible cable sheaths and affecting the service life of the flexible cable. Therefore, a flexible cable winding mechanism is proposed to provide a set of winding mechanisms with good protection and low friction during winding for flexible cables of equipment such as CNC slide rails, thereby improving the service life of the flexible cable and the reliability of the power equipment. Utility Model Content

[0004] In response to the problems in the existing technology, the utility model provides a flexible cable winding mechanism to provide a set of winding mechanisms with good protection and low friction during winding for flexible cables of equipment such as CNC slide rails, thereby improving the service life of flexible cables and the reliability of power equipment.

[0005] The technical solution adopted by the utility model to solve the technical problem is a flexible cable winding mechanism, which includes a drag chain and a positioning mechanism for reducing cable winding friction, wherein at least one positioning mechanism is provided and the positioning mechanism is arranged in a chain compartment of the drag chain;

[0006] The positioning mechanism comprises an upper mounting plate, a lower mounting plate and positioning wheels, wherein the positioning wheels are arranged at equal distances along the bottom of the upper mounting plate and the top of the lower mounting plate.

[0007] By adopting the above technical solution and using a drag chain with a positioning mechanism, a winding mechanism with good protection and low friction during winding is provided for the flexible cables of equipment such as CNC slide rails, thereby improving the service life of the flexible cables and the reliability of the use of power equipment.

[0008] Specifically, support ears are respectively provided on both sides of the positioning wheel, and ends of the support ears are connected to the corresponding upper mounting plate and lower mounting plate.

[0009] Specifically, the positioning wheel is rotatably connected to the support ear via a rotating shaft;

[0010] The positioning wheel includes two groups of nylon wheels and a connecting tube, and the two ends of the connecting tube are respectively connected to the centers of the two groups of nylon wheels.

[0011] By adopting the above technical solution, through the wheel gaps between the upper and lower two groups of nylon wheels, a rolling positioning space is provided for the cable, so that the cable is supported by rolling, and the small frictional force generated during the winding, bending and dragging of the cable can be reduced by the rolling motion, thereby reducing the frictional loss of the cable skin.

[0012] Specifically, a cavity for reducing the weight is arranged inside the nylon wheel.

[0013] By adopting the above technical solution, the weight of the nylon wheel can be reduced, and the operating pressure on the drag chain is relatively low.

[0014] Specifically, corresponding internally threaded mounting blocks are respectively connected to both ends of the bottom of the upper mounting plate and the top of the lower mounting plate, and the internally threaded mounting blocks of the upper mounting plate and the lower mounting plate are connected by a screw rod.

[0015] The beneficial effects of the present utility model:

[0016] Through the drag chain with a positioning mechanism, a winding mechanism with good protection and low friction is realized for the flexible cable of equipment such as a numerical control slide rail during winding, thereby improving the service life of the flexible cable and the reliability of the use of power equipment. Through the setting of the positioning mechanism, it is used to position the use position of the flexible cable that reciprocally winds and bends the flexible cable, avoiding entanglement between cables, and at the same time reducing the friction between the outer skins of the cables, ensuring the stability of the use of the flexible cable, and solving the problem that the flexible cable that needs to frequently perform winding movements, such as a numerical control slide rail, cannot be positioned inside the drag chain, resulting in frequent contact friction between the outer skins of the cables and the inner wall of the drag chain, causing a high wear degree of the outer skin of the flexible cable and affecting the service life of the flexible cable.

[0025] The positioning mechanism 2 includes an upper mounting plate 21, a lower mounting plate 22 and a positioning wheel 24. The positioning wheels 24 are arranged at equal distances along the bottom of the upper mounting plate 21 and the top of the lower mounting plate 22.

[0026] During use, through the drag chain 1 with the positioning mechanism 2, a winding mechanism with good protection and low friction during the winding of the flexible cable for equipment such as a numerical control slide rail is realized, thereby improving the service life of the flexible cable and the reliability of the use of the power equipment.

[0027] In order to reduce the friction force, exemplarily, as Figures 1-3 shown, the present utility model further includes that support ears 23 are respectively arranged on both sides of the positioning wheel 24, and the ends of the support ears 23 are connected to the corresponding upper mounting plate 21 and lower mounting plate 22.

[0028] The positioning wheel 24 is rotatably connected to the support ear 23 through a rotating shaft;

[0029] The positioning wheel 24 includes two groups of nylon wheels 241 and a connecting cylinder 243. The two ends of the connecting cylinder 243 are respectively connected to the centers of the two groups of nylon wheels 241.

[0030] During use, through the wheel gaps between the two groups of upper and lower nylon wheels 241, a rolling positioning space is provided for the cable, so that the cable is supported by rolling, and the small friction force generated during the winding, bending and dragging of the cable can be reduced by the rolling motion, thereby reducing the friction loss of the cable skin.

[0031] The present utility model further includes that a cavity 242 for reducing the weight is arranged inside the nylon wheel 241.

Then, the two ends of the flexible cable are connected to two groups of power control devices and actuating devices that need to be electrically connected. When the equipment is working, the positioning mechanism 2 in the drag chain 1 supports the flexible cable by rolling and positioning, so that the small frictional force generated during the winding, bending and towing of the cable can be reduced by the rolling motion, thereby reducing the frictional loss of the cable skin and reducing the problem of entanglement between the cables.
