Description

Technical Field

[0001] This invention relates to the field of cable cutting technology, and in particular to a cable stripping device. Background Technology

[0002] A cable consists of a core made up of multiple insulated conductors or wires twisted together, and an outer sheath to prevent the core from getting damp and to protect it from mechanical damage. Cables can be divided into communication cables and power cables according to their uses. Both communication cables and power cables have multiple protective layers to protect the core, including an outer sheath, steel wire armor, an inner lining, and an insulation layer. Due to the multiple protective layers, the protection of the core is increased, but the maintenance and processing of the cable are also more difficult.

[0003] When cables are put into use, they must be segmented, which involves cutting the cable. Cutting cables is generally very simple and easy to do. However, because the outer side of the cable is cylindrical, the cable often wobbles from side to side when being cut, making it difficult to cut.

[0004] Therefore, some manufacturers have installed automatic cable cutting equipment according to the cable specifications and models. Most of these devices cut the cable sheath along its length. However, this cutting method is prone to irregular cuts due to the shape of the cutter. Since the next processing step after cable stripping remains unchanged, further circumferential cutting of the longitudinally cut cable is necessary to make the cut more regular.

[0005] However, using the two cutting methods in sequence requires changing the cable cutting tools, which inevitably involves moving heavy cables, making the cutting and splicing of cables extremely laborious. Therefore, a more suitable cutting method and cutting device are needed to cut the cables. Summary of the Invention

[0006] In view of this, the present invention aims to provide a cable stripping device, which provides a cable stripping equipment that is easy to operate and has a good stripping effect.

[0007] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0008] A cable stripping device includes a base and further includes:

[0009] The stripping mechanism includes a disc cutter holder with a through hole that is slidably mounted on the base, and a disc cutter that is rotatably mounted on the disc cutter holder. The disc cutter is capable of clamping the cable to be stripped through the through hole and cutting the cable.

[0010] The driving mechanism includes a driving part disposed on the base, the driving part being connected to the disc cutter holder via a first transmission part, and the first transmission part being connected to the disc cutter via a second transmission part;

[0011] Driven by the drive unit, the first transmission unit can drive the disc cutter holder to slide back and forth along the length direction of the base, and can drive the disc cutter to rotate axially around the through hole through the second transmission unit.

[0012] Furthermore, the first transmission unit includes a lead screw rotatably mounted on the base and connected to the drive unit, the lead screw being arranged along the length direction of the base;

[0013] The disc cutter holder is provided with a connecting block with a threaded hole, and the connecting block is threadedly connected to the lead screw.

[0014] Furthermore, the second transmission unit includes a rotating shaft arranged parallel to the lead screw and rotatably mounted on the base, a first gear assembly disposed between the rotating shaft and the lead screw, and a second gear assembly disposed between the rotating shaft and the disc cutter.

[0015] When the drive unit is activated, the lead screw can drive the disc cutter to rotate through the transmission between the first gear assembly and the second gear assembly.

[0016] Furthermore, the disc cutter includes a disc-shaped base rotatably mounted on the disc cutter holder, a clamping assembly mounted on the base, and a stripping blade mounted on the base, with the through hole penetrating the base. The clamping assembly is used to elastically clamp the cable, and the stripping blade is used to cut the cable.

[0017] Furthermore, the clamping assembly has two clamping blocks arranged opposite to each other in the through hole. Each clamping block is connected to the base through an elastic energy storage part. When the two elastic energy storage parts release energy, they can drive the two clamping blocks to move closer to each other and elastically clamp the cable.

[0018] Furthermore, the disc cutter includes a guide assembly disposed on the base, the guide assembly being capable of guiding the two clamping blocks to move radially along the through hole.

[0019] Furthermore, rollers for pressing against the cable are rotatably provided on the opposite sides of both clamping blocks.

[0020] Furthermore, the elastic energy storage part is a spring, and the two ends of the spring are respectively connected to the clamping block and the base.

[0021] Furthermore, the peeling blades are two blades arranged radially opposite each other along the through hole.

[0022] Furthermore, the base is provided with at least one guide rod arranged along its own length, and the disc cutter holder slides on the guide rod. Compared with the prior art, the present invention has the following advantages:

[0023] The cable stripping device of the present invention, through the provision of a first transmission part and a second transmission part, enables the disc cutter to move along the axial direction of the through hole while rotating around the through hole, so that the movement path of the disc cutter presents a spiral shape, thereby enabling the cable to be stripped in a spiral stripping manner.

[0024] Furthermore, by setting the connection between the connecting block and the lead screw to a threaded connection, the connecting block can drive the disc cutter holder to move back and forth along the axis of the lead screw as the lead screw rotates. Through the provided first and second gear assemblies, the drive unit can drive the disc cutter to rotate, thereby facilitating cable cutting.

[0025] In addition, the clamping components installed on the base can clamp the cable to be cut and fix it in place, thereby facilitating the cutting of the cable by the stripper.

[0026] Furthermore, the clamping block, which is set as a roller, can clamp and fix the cable while rotating around the cable, making it convenient for the stripper to perform circumferential or spiral stripping on the cable. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention in light of the specific circumstances.

[0041] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0042] This embodiment relates to a cable stripping device, one exemplary implementation of which is as follows: Figure 1 and combined Figure 2 As shown. Overall, the cable stripping device mainly includes a base 3, a stripping mechanism, and a drive mechanism. The drive mechanism drives the stripping mechanism to slide on the base 3, while the stripping mechanism strips the cable 4.

[0043] Based on the overall design concept described above, in this embodiment, the stripping mechanism, in order to facilitate the spiral cutting of the cable 4, specifically includes a disc cutter holder 11 with a through hole that is slidably mounted on the base 3, and a disc cutter that is rotatably mounted on the disc cutter holder 11. The disc cutter can clamp the cable 4 to be stripped that is inserted in the through hole and cut the cable 4.

[0044] The drive mechanism includes a drive unit mounted on the base 3. The drive unit is connected to the disc cutter holder 11 via a first transmission unit, and the first transmission unit is connected to the disc cutter via a second transmission unit. Under the drive of the drive unit, the first transmission unit can drive the disc cutter holder 11 to slide back and forth along the length of the base 3, and can drive the disc cutter to rotate axially around the through hole via the second transmission unit. Preferably, the drive unit can be a drive motor mounted on the base.

[0045] In detail, the first transmission unit includes a lead screw 211 rotatably mounted on the base 3 and connected to the drive unit. The lead screw 211 is arranged along the length of the base 3. In order to realize the spiral stripping of the cable 4 by the stripping mechanism, in this embodiment, the disc cutter holder 11 is provided with a connecting block 13 with a threaded hole, and the connecting block 13 is threadedly connected to the lead screw 211. With this configuration, as the drive unit drives the lead screw 211 to rotate, the disc cutter holder 11, which is threadedly connected to the lead screw 211, can move back and forth along the axis of the lead screw 211 as the lead screw 211 rotates.

[0046] The second transmission unit includes a rotating shaft 221 rotatably mounted on the base 3 and arranged parallel to the lead screw 211, a first gear assembly 222 disposed between the rotating shaft 221 and the lead screw 211, and a second gear assembly 223 disposed between the rotating shaft 221 and the disc cutter. When the drive unit drives the lead screw 211 to rotate, the lead screw 211 can drive the disc cutter to rotate through the transmission of the first gear assembly 222 and the second gear assembly 223. Regarding the rotation of the disc cutter holder on the disc cutter holder 11, the disc cutter is mounted on the disc cutter holder 11 through a connecting bearing and is meshed with the second gear assembly 223 through a gear ring.

[0047] In practical implementation, the second gear assembly 223 mentioned above is rotatably mounted on the disc cutter holder 11 along its own axis. Furthermore, the second gear assembly 223 is keyed to the rotating shaft 221, and a groove is provided on the rotating shaft 221 to allow the key to slide. In this way, as the disc cutter moves along the axis of the lead screw 211, the rotating shaft 221 can always provide driving force for the rotation in the disc cutter holder, thereby facilitating the disc cutter to cut the cable 4 in a helical stripping manner.

[0048] The disc cutter includes a disc-shaped base 121 rotatably mounted on a disc cutter holder 11, a clamping assembly 122 mounted on the base 121, and a peeling blade 123 mounted on the base 121, with a through hole penetrating the base 121. The clamping assembly 122 is used for elastic clamping. Figure 4 The cable 4 shown is cut by a stripper 123. The arrangement of the stripper 123 on the base 121 and the structural form of the stripper 123 can be found in [reference needed]. Figure 2 and 3 .

[0049] To be more specific, it is still as follows Figure 2 As shown, the clamping assembly 122 has two clamping blocks 1221 arranged opposite each other within the through hole. Each clamping block 1221 is connected to the base 121 via an elastic energy storage section 124. When the two elastic energy storage sections 124 release energy, they can drive the two clamping blocks 1221 to move closer together and elastically clamp the cable 4. Rollers 1222 for pressing against the cable 4 are rotatably provided on the opposite sides of the two clamping blocks 1221. The elastic energy storage section 124 is a spring, and the two ends of the spring are respectively connected to the clamping block 1221 and the base 121. There are two stripping blades 123 arranged radially opposite each other along the through hole.

[0050] In addition, as Figure 3 and Figure 4 As shown, the rotary cutter also includes a guide assembly 125 disposed on the base 121. The guide assembly 125 can guide the two clamping blocks 1221 to move radially along the through hole. The guide assembly 125 includes two guide rods. The guide rods can be disposed on the base 121 in a manner that completely passes through the clamping blocks 1221, or a limiting protrusion can be formed at the end of the guide rod away from the connection with the base 121. Correspondingly, the clamping blocks 1221 are formed with two through holes of different inner diameters as shown in the figure, to prevent the two clamping blocks 1221 from getting too close together and to improve the problem that the guide rods passing through the clamping blocks 1221 may obstruct the passage of the cable 4.

[0051] As configured above, the roller 1222 can press against the cable 4 to fix the cable 4 while rotating the disc cutter, and can also rotate along the circumference of the cable 4, thereby facilitating the disc cutter to spirally strip the cable 4. In specific implementation, when the roller 1222 is installed on the clamping block 1221, it can be set on the clamping block 1221 in a form where the orientation of its own axis is adjustable. This assembly method can be referred to as the assembly method of swivel casters, and will not be described in detail here.

[0052] In addition to the feasible implementation methods described above, in this embodiment, for the movement of the disc tool holder 11 on the base 121, there is an alternative implementation method. Specifically, the structure of the disc tool holder 11 is as follows: Figure 2As shown, a gear capable of rotating along its own axis is connected to the edge of the disc cutter holder 11 via a connecting bearing, along with a motor that drives the gear. This gear meshes with the outer gear ring of the disc cutter. The motor is also mounted on the disc cutter holder 11 and is electrically connected to an external power source. It should be further noted that the power cord connecting the motor to the external power source is routed to the bottom of the base 3 via a cable chain. Furthermore, the gear has an internal thread in its central opening, which is threadedly connected to the lead screw 211 in the aforementioned embodiment (here, the lead screw 211 is fixedly mounted on the base 3 and cannot rotate). Thus, by driving the gear with the motor, the disc cutter can rotate while simultaneously moving along the axial direction of the lead screw 211.

[0053] In accordance with the various embodiments described above, the base 121 is further provided with, for example... Figure 5 The fixing plate 31 shown is used to fix the cable 4 to prevent it from moving along its own axis. This fixing plate 31 also has the clamping part mentioned above, but it is fixed to the base 3 and does not move with the cable 4. Meanwhile, in this embodiment, to enhance the structural strength of the base 3, at least one guide rod, preferably two, is provided on the base 3 along its own length. The blade holder 11 slides on the guide rod, and the fixing plate 31 is fixedly mounted on the guide rod.

[0054] In summary, the cable stripping device of this embodiment, through the provision of a first transmission unit and a second transmission unit, enables the disc cutter to rotate around the through hole while also moving along the axial direction of the through hole, so that the movement path of the disc cutter is helical, thereby enabling the cable 4 to be stripped in a helical stripping manner. By setting the connection between the connecting block 13 and the lead screw 211 as a threaded connection, as the lead screw 211 rotates, the connecting block 13 can drive the disc cutter holder 11 to move back and forth along the axial direction of the lead screw 211. Through the provision of a first gear assembly 222 and a second gear assembly 223, the drive unit can drive the disc cutter to rotate, thereby facilitating the cutting of the cable 4. Through the clamping assembly 122 provided on the base 121, the cable 4 to be cut can be clamped and fixed, thereby facilitating the stripping blade 123 to cut the cable 4. Utilizing the rotation of the roller 1222, while clamping and fixing the cable 4, it can also rotate around the cable 4, thereby facilitating the stripping blade 123 to perform circumferential or helical stripping of the cable 4.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
