Description

Technical Field

[0001] The invention relates to the technical field of cable stripping equipment, in particular to a cable stripping tool and a stripping machine. Background Art

[0002] A cable is a device for transmitting electric energy or signals, usually composed of several or several groups of wires. From the inside to the outside, the cable includes at least a conductor, a shielding layer and an insulating layer, wherein the shielding layer is generally made of metal, such as aluminum foil, and the insulating layer is made of various rubber materials. During the cable processing, the shielding layer and the insulating layer need to be cut off to achieve the purpose of stripping. However, the current stripping device has a cutter that is fixedly connected to the cutter disc. When the shielding layer is peeled, the aluminum foil is not elastic and is squeezed and deformed, resulting in an irregular surface shape. If the position of the cutter is not adjusted at this time, the aluminum foil may not be peeled properly or the conductor may be damaged during the peeling process, thereby affecting the stripping effect.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0028] It should be understood that, in the description of the present application, the terms "upper", "lower", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. The terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated, that is, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In addition, unless otherwise specified, "multiple" means two or more.

[0029] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0030] like Figure 1-7 As shown, the cable stripping tool 100 provided in some embodiments of the present invention is used for peeling and peeling of the cable 200, and the cable stripping tool 100 includes a moving component and an adaptive tool holder component 3. Specifically, the moving component includes a slide rail 1 and a slider 2, and the slider 2 moves in the slide rail 1 to adjust the distance between the adaptive tool holder component 3 and the cable 200. The adaptive tool holder component 3 can adapt to the peeling and peeling of different material layers inside the cable 200 to ensure a good peeling effect.

[0031] The slide rail is used to be installed on the end surface of the turntable 300. The surface of the slide rail 1 facing away from the turntable 300 has a slide groove 11. In order to prevent the slider 2 from slipping out of the slide groove 11, the width of the opening of the slide groove 11 extending out of the slide rail 1 is smaller than the width of the slide groove 11 itself, and the shape of the slider 2 is adapted to the slide groove 11. The middle part of the turntable 300 is configured to allow the cable 200 to pass through. The middle part of the turntable is provided with an accommodating space along its axial direction to allow the cable 200 to pass through. In addition, in order to ensure the structural stability of the cable 200 during the stripping process, a clamping mechanism is provided in the accommodating space to fix the position of the cable 200. For example, the clamping mechanism uses a finger cylinder.

[0032] The slider 2 is slidably disposed in the slide groove 11, and the slider 2 has a protrusion 21 extending out of the groove, and a stopper 22 is disposed on the side of the protrusion 21. In order to ensure the accuracy of the movement of the slider 2, the slider 2 is driven by a power device, and illustratively, the power device is a cylinder or an oil cylinder or an electric push rod, which is installed at the end of the slide rail 1 through a bracket, and the output end of the cylinder or the oil cylinder or the electric push rod is connected to the slider 2, so as to achieve accurate control of the movement distance of the slider 2 in the slide groove.

[0033] The adaptive tool holder assembly 3 includes a rotating block 31, a rotating pin 32, a blade 33 and a spring 34. The rotating block 31 is rotatably connected to the protruding portion 21 through the rotating pin 32. The blade 33 is installed on the rotating block 31. The end of the blade 33 extending out of the rotating block 31 has a side edge 331 and an inclined main edge 332. Specifically, the end of the main edge 332 close to the side edge 331 is closer to the cable 200 than the end away from the side edge 331. The side of the rotating block 31 abuts against the stopper 22. The function of the stopper 22 is to block the rotating block 31 so that the rotating block 31 can only rotate counterclockwise. The first end of the spring 34 is installed on the protruding portion 21, and the second end of the spring 34 abuts against the end face of the rotating block 31 away from the stopper 22. The function of the spring 34 is that when the rotating block 31 is subjected to force to produce a counterclockwise deflection, the spring 34 can continuously apply elastic force to the rotating block 31.

[0034] like Figure 1 and 4 As shown, in this embodiment, when the turntable 300 rotates clockwise, the side edge 331 of the blade 33 peels the cable 200, and the blade 33 abuts against the block 22 to keep the blade position stable. At this time, the blade is suitable for peeling the insulation layer around; when the turntable 300 rotates counterclockwise, the main edge 332 of the blade 33 peels the cable 200, and the rotating block 31 drives the blade 33 to deflect counterclockwise around the rotating pin 32, so that the spring 34 is compressed, and the spring 34 continuously applies elastic force to the blade 33, which can adapt to the peeling of the shielding layer that is easy to deform, avoid the shielding layer from being completely cut off or damaging the conductor inside the shielding layer, and of course, it can also adapt to the peeling of the insulation layer around. Finally, the peeling and skinning of different material layers inside the cable 200 is achieved to ensure a good skinning effect. In order to achieve a better peeling effect, the installation position of the slide rail 1 on the turntable 300 or the position where the cable 200 is clamped and fixed can be adjusted to meet the peeling position requirements of the main edge 332 or the side edge 331 of the blade 33 for the cable 200.

[0035] It should be noted that the key to overcoming the problem that the shielding layer cannot completely cut off or damages the conductor inside the shielding layer is to adjust the depth of the blade 33 rotating into the shielding layer. According to the thickness of the shielding layer, a spring 34 can be configured to adapt to the thickness of the shielding layer. The elastic force generated by the spring 34 ensures that the depth of the blade 33 rotating into the shielding layer is equal to the thickness of the shielding layer, which can overcome the above problem. Figure 5 As shown, during the actual peeling process, the blade 33 relies on the tip formed by the side edge 331 and the main edge 332 to perform peeling.

[0036] like Figure 2 As shown, in some embodiments, a mounting seat 23 is provided on the side of the protrusion 21 away from the stopper 22, and a mounting groove is provided at the end of the mounting seat 23, and the first end of the spring 34 is installed in the mounting groove. The width of the protrusion 21 is adapted to the width of the opening of the slide groove 11 extending out of the slide rail 1, and the width of the protrusion 21 is smaller than the width of the slider 2, so as to prevent the slider 2 from slipping out of the slide groove 11.

[0037] like Figure 1 As shown, in some embodiments, the adaptive blade holder assembly 3 further includes a cover plate 35, the two sides of which are correspondingly mounted on the stopper 22 and the mounting seat 23, and the cover plate 35 is spaced apart from the blade 33. The cover plate 35 has a protective effect on the blade 33 and the rotating block 31.

[0038] like Figure 2 As shown, in some embodiments, the side of the rotating block 31 away from the stopper has an inwardly recessed receiving groove 313, and the receiving groove 313 is arranged below the spring 34. The protruding portion 21 is also provided with a screw seat 24, and the screw seat 24 is arranged in the receiving groove 313. The outer wall of the screw seat 24 is spaced from the inner wall of the rotating block 31, so that the rotating block 31 has a rotating space. The screw seat 24 is used to install the cover plate 35 by screws, so that both sides of the cover plate 35 can be installed and fixed, ensuring that the installation structure of the cover plate 35 is stable and reliable.

[0039] In some embodiments, the end surface of the rotating block 31 away from the stopper 22 has a stopper 311, and when the turntable 300 rotates clockwise, the stopper 311 abuts against the mounting seat 23; when the turntable 300 rotates counterclockwise, the stopper 311 is separated from the mounting seat 23. The stopper 311 and the stopper 22 can block the two sides of the rotating block 31 to ensure that the position of the rotating block 31 is stable when the turntable 300 rotates clockwise.

[0040] In some embodiments, the slider 2 moves in the slide slot 11 to adjust the distance between the blade 33 and the cable 200. Thus, the rotary cutting depth of the blade 33 on the cable can be adjusted.

[0041] In some embodiments, the rotating block 31 has a slot 312 , and the blade 33 is installed in the slot 312 . The end of the blade 33 away from the main edge 332 is flush with the end surface of the rotating block 31 , so that the blade 33 is easy to install.

[0042] In some embodiments, the blade 33 is fixedly connected to the rotating block 31 by a bolt 333 to maintain a stable installation structure of the blade 33. The end of the blade 33 away from the main edge 332 has a groove 334, and the end of the rotating pin 32 is arranged in the groove 334, which facilitates the positioning of the installation position of the blade 33.

[0043] In some embodiments, the angle between the side blade 331 and the main blade 332 is 30-60°, and the side blade is perpendicular to the surface of the cable 200. At this time, the larger the angle between the side blade 331 and the main blade 332, the wider the contact surface between the main blade 332 and the cable, and the main blade 332 is less likely to wear, but the peeling resistance is large; conversely, the smaller the angle between the side blade 331 and the main blade 332, the narrower the contact surface between the main blade 332 and the cable, and the main blade 332 is more likely to wear, but the peeling resistance is small.

[0044] Some other embodiments of the present invention provide a cable stripping machine, comprising at least two groups of cable stripping cutters 100 provided in some embodiments, and the cable stripping cutters 100 are arranged around the outer circumference of the cable 200 .

[0045] Based on the above structural setting, the cable stripping machine of the present invention can adapt to the surrounding peeling of the easily deformed shielding layer, so as to avoid the shielding layer not being completely cut off or damaging the conductor inside the shielding layer. Finally, the peeling and peeling of different material layers inside the cable 200 can be achieved to ensure a good peeling effect.

[0046] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
