Description

Technical Field

[0001] The utility model relates to the field of automation, in particular to a cable clamping mechanism. Background Art

[0002] When manufacturing cables with connectors, it is necessary to first strip the sheath of one end of the cable to expose the internal wires, then insert the wires into the terminals, and then perform subsequent operations such as crimping the terminals. During this process, the multiple strands of wire in the cable will spread out due to the loss of the constraints of the sheath, and not all of them will be inserted into the terminals, reducing the yield rate of the cable.

[0003] The existing cable clamping mechanism is provided with two clamping jaws, one clamping the part holding the wire skin, and the other clamping the wire. After approaching the terminal, the clamping jaw holding the wire is released, so that the wire remains in a constrained state before entering the terminal, thereby reducing the occurrence of the aforementioned problems. However, the clamping space of the two clamping jaws must remain concentric, and the clamping jaws need to be clamped synchronously and released asynchronously. Therefore, this clamping mechanism structure needs to be provided with a linkage device to reduce the number of power sources used and reduce costs. The existing linkage mechanism is a gear and a rack, which makes this type of clamping mechanism have concentric pairs during installation and debugging, which requires multiple debugging to achieve the set effect.

[0027] Figures 1 to 6 A cable clamping mechanism according to an embodiment of the utility model comprises:

[0028] The mounting seat 1 is formed with a first guide groove 11 and a second guide groove 12 for the cable clamping assembly 2 and the wire clamping assembly 3 to move; the two guide grooves are arranged in parallel; the mounting seat 1 is recessed in the area between the two guide grooves to form a rotation groove 13, and the bottom of the rotation groove 13 protrudes upward to form a rotation axis 14;

[0030] The wire clamping assembly 3 includes an upper wire clamping element 31 slidably arranged in the first guide groove 11, a lower wire clamping element 32 slidably arranged in the second guide groove 12, a linkage plate 33 of the wire clamping assembly 3 rotatably mounted on the rotating shaft 14, and a wire clamping driving member 34 driving the upper wire clamping element 31 to slide; oblong connecting holes are provided at both ends of the linkage plate 33 of the wire clamping assembly 3, and the connecting holes cooperate with the linkage shafts correspondingly formed by the upper wire clamping element 31 and the lower wire clamping element 32 to form a variable structure; the wire clamping driving member 34 drives the variable structure to move.

[0031] Optionally, the cable upper clamping element 21 includes a cable upper clamping driving rod 211 and a cable upper clamping claw 212, the cable upper clamping driving rod 211 is arranged at one end of the cable upper clamping driving rod 211, and the cable upper clamping driving rod 211 slides in the first guide groove; the cable lower clamping element 22 includes a cable lower clamping driving rod 221 and a cable lower clamping claw 222, the cable lower clamping driving rod 221 is arranged at one end of the cable lower clamping driving rod 221, and the other end of the cable lower clamping driving rod 221 is connected to the movable end of the cable clamping driving member 24; the cable lower clamping driving rod 221 slides in the second guide groove;

[0032] Furthermore, the upper clamping claw 212 of the cable includes an upper clamping claw 2121 and an upper clamping claw seat 2122, and a spring is provided on the end face of the upper clamping claw 2121, one end of the spring abuts against the upper clamping claw seat 2122, and the other end abuts against the upper clamping claw 2121, and the upper clamping claw 2121 is movably arranged in the upper clamping claw seat 2122, and the spring pushes the upper clamping claw 2121 to extend out of the upper clamping claw seat 2122; the lower clamping claw 222 of the cable includes a lower clamping claw 2221 and a lower clamping claw seat 2222, and a spring is provided on the end face of the lower clamping claw 2221, one end of the spring abuts against the lower clamping claw seat 2222, and the other end abuts against the lower clamping claw 2221, and the lower clamping claw 2221 is movably arranged in the lower clamping claw seat 2222, and the spring pushes the lower clamping claw 2221 to extend out of the lower clamping claw seat 2222.

[0033] The structures and activities of the cable clamping assembly 2 and the wire clamping assembly 3 of the utility model are similar. Therefore, the specific structure and activities of the cable clamping assembly 2 are further described below:

[0034] The cable upper clamping element 21 and the cable lower clamping element 22 are formed into a variable "H"-shaped structure through the cable clamping assembly linkage plate 23. Since the two vertical parts of the H-shaped structure are respectively arranged in the parallel first guide groove 11 and the second guide groove 12, the movement directions of the two clamping elements are parallel or coaxial. It can be seen from the figure that the upper cable clamping claw 212 and the lower cable clamping claw 222 finally move in a coaxial manner to clamp the cable. Of course, the upper and lower clamping claws are formed by setting a toothed structure to form a mechanism that can give way to each other when closed, and the space inside the upper and lower clamping claws is the clamping space of the cable;

[0035] In the process of clamping the cable, after the wire is inserted into the terminal, the external device will have an action of sending the wire in the length direction toward the terminal. At this time, the wire clamping assembly 3 will be loosened, and the cable clamping assembly 2 has limited clamping force on the cable because the upper and lower clamping jaws are movably arranged in the corresponding clamping jaw seats, which makes the above-mentioned cable movement possible. Of course, the cable's mobility is limited, and it is still clamped after the movement;

[0036] Back to the H-shaped variable structure, specifically, the middle sections of the upper cable clamping drive rod 211 and the lower cable clamping drive rod 221 each have a groove, and a vertical rod is erected in the groove. When the vertical rod extends into the oblong holes at both ends of the cable clamping assembly linkage plate 23, it constitutes the necessary connection method of the movable structure. In the prior art, this linkage structure is composed of a combination of gears and racks. Therefore, even if the meshing of the gears and racks is fine, there is still a problem of complex adjustment, because the cable clamping assembly 2 and the wire clamping assembly 3 need to keep the cable in a horizontal state in space. If the traditional gear and rack meshing method is adopted, in order to adjust to the above-mentioned effect, it needs to be disassembled and assembled repeatedly. The linkage structure of the utility model eliminates this debugging process, so that the entire movable structure can find the center by itself. Of course, it is still necessary to fine-tune the clamping center of the wire clamping assembly 3, but only the clamping claws need to be adjusted.

[0037] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0038] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.
