Detailed Description
the present invention is described in detail below with reference to the attached drawings.
As shown in fig. 1 and 2, the present invention provides a cutter assembly mounted on a housing 1 of a cable cutting apparatus for cutting a cable sheath. The cutting blade assembly includes:
A base housing 2 provided on the housing 1;
the cutter is arranged in the base shell 2, extends out of the base shell 2 towards one end of the cable and is attached to the end face of the cable sheath so as to cut the cable sheath; and
and the limiting piece is arranged in the base shell 2 and can move relative to the base shell 2, one end of the limiting piece, facing the cable, extends out of the base shell 2, a position difference exists between the limiting piece and one end, located outside the base shell 2, of the cutter in the axial direction of the cable, and when the cable sheath is cut, one end, located outside the base shell 2, of the limiting piece abuts against the end face of the cable sheath to limit the cutting depth of the cutter. That is, when the cutter cuts the cable sheath, the cutting depth is equal to the value of the position difference between the stopper and the cutter. Because the cutter is when cutting the cable crust, the locating part constantly offsets with the terminal surface of cable crust, therefore no matter how fast the cutting speed that cable cutting device set up, the depth of cut of cutter still is a definite value, can not lead to the depth of cut to increase sharply because of the cutting speed is too fast, leads to appearing because of the too big phenomenon of cutting failure of depth of cut, and the cutting action of supplementary cutter is stable smooth and easy.
As shown in fig. 2, further, the cutter includes:
the knife box 3 is movably arranged in the base shell 2 and can be limited in the base shell 2, one end of the knife box 3 facing the cable extends out of the base shell 2, namely the knife box 3 is partially positioned in the base shell 2 and partially positioned outside the base shell 2, and the whole knife box 3 can move relative to the base shell 2; and
And the cutting knife 4 is arranged at one end of the knife box 3 extending out of the base shell 2, the cutter cuts the cable sheath through the cutting knife 4, and the blade part of the cutting knife 4 is attached to the end surface of the cable sheath at the initial moment of cutting the cable sheath so as to drive the cutting knife 4 to cut the cable when the cable cutting device moves.
In order to facilitate adjustment of the position of the cutting blade 4 with respect to the cable, the blade case 3 in this embodiment is movably disposed in the blade case 3. Referring to fig. 1, a threaded hole 7 with a long strip shape is formed in one end of the knife box 3 located in the base shell 2, an adjusting bolt 8 penetrates through the position, corresponding to the threaded hole 7, of the base shell 2, the adjusting bolt 8 is connected with the threaded hole 7 and can rotate relative to the base shell 2 to drive the knife box 3 to move along the radial direction of the cable, and meanwhile, the knife box 3 can be limited in the base shell 2. That is, the user can adjust the length of the blade case 3 extending out of the base housing 2 by the adjusting bolt 8, thereby adjusting the position of the cutting blades 4 with respect to the cable.
in order to further limit the knife box 3, the knife box 3 is prevented from shifting when cutting cables, which affects the cutting effect, in this embodiment, a strip-shaped hole is further formed in the base housing 2 along the moving direction of the knife box 3, and a first fastening member 9 (in this embodiment, the first fastening member 9 is a fastening screw) is disposed in the strip-shaped hole, and can move along the strip-shaped hole and can be tightly pressed against the limit knife box 3. When the knife box 3 is to be moved, the first fastening piece 9 is rotated to be separated from the knife box 3; when the cable sheath is to be cut horizontally, namely when the cutting surface of the cable sheath is to be always vertical to the axis of the cable, the first fastening piece 9 is rotated after the position of the knife box 3 is adjusted, so that the knife box 3 is tightly pressed against the knife box 3, and the knife box 3 is prevented from moving, so that the cutting surface of the cable sheath is a plane instead of a circular table surface.
Continuing to refer to fig. 2, the limiting member is a top rod 5, and one end of the top rod 5 located in the base housing 2 is connected to the base housing 2 through a spring 6, so that the top rod 5 can move relative to the base housing 2. The base shell 2 is further provided with a second fastening piece 10 (in the embodiment, the second fastening piece 10 is a gripping knob) for abutting to limit the push rod 5.
Furthermore, the cutter assembly provided by the invention not only can horizontally cut the cable (namely, the end surface of the outer skin of the cable is a circular ring surface vertical to the cable after the cable is cut), but also can taper the cable, namely, the end surface of the outer skin of the cable is a circular table surface after the cable is cut. Specifically, one (or more) sliding grooves 11 may be disposed on the housing 1 along the radial direction of the cable, and the base housing 2 is provided with a protrusion 12 (or protrusion) which is located in the sliding groove 11 and can slide along the sliding groove 11, so that the protrusion 12 drives the base housing 2 to move integrally along the sliding groove 11, that is, the cutting blade 4 assembly moves integrally close to or away from the cable along the radial direction of the cable. Meanwhile, the base shell 2 is further provided with a fastener for limiting the position of the base shell 2, namely, the fastener is used for preventing the base shell 2 from moving relative to the shell 1. The fastening member in this embodiment is a third fastening member 13 penetrating the base shell 2, and the third fastening member 13 can abut against the sliding groove 11 to limit the base shell 2 on the housing 1 (in this embodiment, the third fastening member 13 is a gripping knob). When in application:
when the cable sheath is cut (namely, the cable sheath is stripped along the radial direction of the cable, and the end surface of the cable sheath is a circular ring surface vertical to the cable when the cutting is finished), the third fastening piece 13 is tightly pressed against the sliding groove 11 to limit the base shell 2, and meanwhile, the second fastening piece 10 is tightly pressed against the limiting ejector rod 5;
as shown in fig. 3, when the outer skin of the cable is to be obliquely cut, i.e. the cable is to be tapered, the third fastening member 13 releases the limit of the base shell 2, and the second fastening member 10 also releases the limit of the top rod 5, so that the base shell 2 can move relative to the housing 1 in the radial direction of the cable, and the top rod 5 can move relative to the base shell 2 in the radial direction of the cable, so that the end of the top rod located outside the base shell 2 can abut against the cable in real time, and the position of the cutting blade 4 is limited by limiting the position of the base shell 2. That is, when tapering the cable, the user can pull the base housing 2 gradually outward in the radial direction of the cable based on whether the jack 5 abuts against the outer skin of the cable, so that the cutting surface is a circular table. Because the inside of the ejector rod 5 is connected with the base shell 2 through a spring 6, the ejector rod 5 can compress the spring 6 at the initial stage of cutting during the specific implementation, and the spring 6 is gradually reset along with the movement of the base shell 2, so that the ejector rod 5 can be attached to the cable in real time under an undefined state.
As shown in fig. 3, the present invention also discloses a cable cutting device, which comprises a housing 1 and the cutting knife assembly disposed on the housing 1. Wherein, this casing 1 has the through wires hole in order to pass through the through wires hole cover on the cable, and this casing 1 can be relative cable rotation.
The above embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and the scope of the present invention is defined by the claims. Various modifications and equivalents may be made by those skilled in the art within the spirit and scope of the present invention, and such modifications and equivalents should also be considered as falling within the scope of the present invention.
