Description

Technical Field

[0001] The invention relates to the technical field of wire strippers, in particular to a wire stripper. Background Art

[0002] In the connection between power transmission and electronic equipment, wires and cables play a vital role as the basic carriers of power and information transmission. They are widely used in various power systems, communication networks and household appliances, ensuring efficient energy transfer and stable signal transmission. However, in practical applications, especially in complex line layouts or difficult-to-reach environments, it is often necessary to maintain, repair or upgrade the cables or wires that have been put into use. At this time, it is necessary to strip the insulation layer of the wire to expose the internal conductor part for wiring or detection. It is worth noting that in many scenarios, due to space constraints or equipment operating status requirements, these cables or wires cannot be easily removed. Therefore, on-site stripping operations without interrupting service have become an important requirement.

[0003] At present, there are some wire stripping equipment on the market, which are usually operated manually. The most representative one is the design of lifting the stripping caliper by a long pole. This stripping caliper is designed with a sharp cutting blade. The operator needs to put the caliper on the wire to be stripped first, and then drive the cutting blade to rotate by power. The inclined cutting blade cuts the wire and moves along the axial direction of the wire, thereby cutting the insulation layer and completing the stripping process.

[0004] However, after the stripping caliper is wrapped around the wire, it lacks the design of automatic tightening and loosening. When using it, it is necessary to use additional tools or manual force to ensure that the caliper is wrapped around the wire to avoid slipping or loosening during rotation and cutting. This not only increases the complexity of the operation, but also may affect the accuracy and safety of the stripping. Similarly, after the stripping is completed, the caliper needs to be manually unlocked. The inclined cutting blade makes it difficult to cut off the outer skin, which also requires manual operation. Such manual operation can easily cause operator fatigue and increase the risk of operating errors. Summary of the invention

[0029] Embodiment: A wire stripper, such as Figure 1-Figure 10As shown, it includes a mounting shell 1, a transmission rod 11, a sleeve 12, a first bevel gear 13, a second bevel gear 14, a transmission gear shaft 15, a telescopic component 2, an automatic clamping and placing component 3, a cutting component 4 and a cutting component 5.

The transmission rod 11 is rotatably connected in the sleeve 12, and the upper end of the transmission rod 11 extends into the mounting shell 1 and is fixedly connected to the first bevel gear 13. The transmission gear shaft 15 is rotatably connected in the mounting shell 1, and the front end of the transmission gear shaft 15 is fixedly connected to the second bevel gear 14. The second bevel gear 14 is meshed with the first bevel gear 13, and the second bevel gear 14 and the first bevel gear 13 form a bevel gear set to realize power transmission in the vertical direction. The transmission rod 11 is provided with a telescopic component 2 for adjusting the height of the mounting shell 1, and the mounting shell 1 is provided with an automatic clamping component 3 for automatically tightening and loosening the wire.

[0030] like Figure 1 and Figure 4 As shown, the telescopic assembly 2 includes a spline shaft 21, a fixing screw 22 and an extension tube 23. A spline hole 111 is opened at the bottom of the transmission rod 11. The spline shaft 21 is slidably connected to the transmission rod 11 through the spline hole 111. The spline shaft 21 and the transmission rod 11 are spline-connected, and can slide against each other and rotate synchronously. A hexagonal joint connected to a power source is provided at the bottom of the spline shaft 21. The power source can be a motor or manpower. The hexagonal joint is connected through a motor, or a tool such as a wrench is used to connect the hexagonal joint. The spline shaft 21 is rotated by relying on a longer lever arm. The extension tube 23 is slidably connected to the outside of the sleeve 12. The extension tube 23 is threadedly connected with a fixing screw 22. The fixing screw 22 is squeezed and fitted with the sleeve 12. The bottom of the spline shaft 21 is rotatably connected to the bottom of the extension tube 23, so when the extension tube 23 is moved, the spline shaft 21 will also move with it.

[0031] like Figure 1 As shown, an insulating rubber sleeve 24 is also included, and the extension tube 23 is sleeved with the insulating rubber sleeve 24.

[0032] like Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the automatic clamping assembly 3 includes a triangular block 101, a double-track arc rack 31, a single-track arc rack 32, a wedge block 33, an elastic member 3301, an arc guide rod 34 and an annular reset spring 35. The top of the mounting housing 1 is rotatably connected with the double-track arc rack 31. The double-track arc rack 31 is composed of two arc racks connected in the middle, and the middle is empty. The single-track arc rack 32 is slidably connected in the middle of the double-track arc rack 31. The double-track arc rack 31 is connected with an arc guide rod 34. The single-track arc rack 32 is slidably connected to the arc guide rod 34. The arc guide rod 34 is sleeved with an annular reset spring. Spring 35, one end of the annular return spring 35 is connected to the double-track arc rack 31, and the other end is connected to the single-track arc rack 32. The double-track arc rack 31 and the single-track arc rack 32 are both meshed with the transmission gear shaft 15. An annular slide groove is opened on the mounting shell 1, and a triangular stopper 101 is connected in the slide groove. The end of the single-track arc rack 32 is slidably connected with a wedge block 33. An elastic member 3301 is arranged in the single-track arc rack 32, one end of the elastic member 3301 is connected to the single-track arc rack 32, and the other end is connected to the wedge block 33. The wedge block 33 corresponds to the position of the slide groove, and the wedge block 33 is limitedly matched with the triangular stopper 101.

[0033] like Figure 2 , Figure 3 , Figure 5 , Fig. 9 and Fig.10 As shown, the cutting assembly 4 includes a single-track connecting frame 41, a double-track connecting frame 42, a mounting shaft 43, a torsion spring 44 and a cutting blade 45. The double-track arc rack 31 is connected to the double-track connecting frame 42 on the front side, and the double-track connecting frame 42 is rotatably connected to the mounting housing 1. The single-track arc rack 32 is connected to the single-track connecting frame 41 on the front side, and the single-track connecting frame 41 is slidably connected to the double-track connecting frame 42. When the rear end of the single-track connecting frame 41 rotates with the single-track arc rack 32, it is slidably connected to the double-track arc rack 31 The double-track arc-shaped rack 31 is provided with an arc groove slidably connected thereto to ensure smooth rotation of the single-track connecting frame 41. A mounting shaft 43 is provided on the inner side of the single-track connecting frame 41. A cutting blade 45 is rotatably connected to the mounting shaft 43. The cutting blade 45 is tilted. The mounting shaft 43 can be adjusted and fixed in position, so as to adjust the position of the cutting blade 45 according to the size of the wire, so that the outer skin of the wire cut off during the stripping process is continuous. A torsion spring 44 is connected between the cutting blade 45 and the mounting shaft 43.

[0034] like Figure 2 , Fig. 9 and Fig.10As shown, the cutting assembly 5 includes a pull rope 51, a bending block 52 and a V-shaped cutting block 53. The bending block 52 is rotatably connected to the monorail connecting frame 41. One end of the pull rope 51 is connected to the cutting blade 45, and the other end is connected to the bending block 52. The end of the bending block 52 close to the inner side of the monorail connecting frame 41 is connected to the V-shaped cutting block 53, and the V-shaped cutting block 53 is squeezed and matched with the outer skin of the conductor.

[0035] Before the staff lifts the installation shell 1, they first connect the power source to the spline shaft 21 and turn on the power source. The first bevel gear 13 is driven to rotate through the spline shaft 21 and the transmission rod 11, so that the first bevel gear 13 drives the second bevel gear 14 and the transmission gear shaft 15 meshing therewith to rotate. The transmission gear shaft 15 is used to drive the automatic clamping assembly 3, so that the single-track arc rack 32 overlaps with the double-track arc rack 31. Then, the height of the installation shell 1 is adjusted by the telescopic assembly 2, and the installation shell 1 is lifted. The double-track arc rack 31 is sleeved on the wire. The power source is transmitted through the spline shaft 21 and the transmission rod 11, and the automatic clamping assembly 3 is driven through the first bevel gear 13, the second bevel gear 14 and the transmission gear shaft 15 to complete the sleeve of the wire, and the cutting assembly 4 is driven by the automatic clamping assembly 3 to cut the outer skin of the wire. After the cutting is completed, the cutting assembly 5 cuts the outer skin, and the installation shell 1 is lowered after the wire is released to complete the wire stripping work. And it only needs to control the start and stop of the power source, which reduces the steps of manual operation and automates the stripping process.

[0036] When adjusting the height of the mounting housing 1, first loosen the fixing screw 22, then hold the sleeve 12 with one hand, and pull the extension tube 23 up and down with the other hand. The surface of the extension tube 23 is covered with an insulating rubber sleeve 24. The insulating rubber sleeve 24 increases the friction between the palm and the extension tube 23 and isolates the current. Therefore, when working, hold the insulating rubber sleeve 24 with both hands, and the extension tube 23 drives the spline shaft 21 to move together. Since the transmission rod 11 has a spline hole 111, the spline shaft 21 slides in the transmission rod 11. After the adjustment is completed, release it. Extension tube 23, tighten the fixing screw 22, the fixing screw 22 and the sleeve 12 are squeezed, thereby limiting the position of the extension tube 23 on the sleeve 12, and completing the adjustment of the distance between the installation housing 1 and the bottom of the spline shaft 21. The bottom of the spline shaft 21 can be connected to the motor, or a wrench can be used to clamp the hexagonal connector at the bottom of the spline shaft 21 to ensure that the spline shaft 21 can rotate. The rotation of the spline shaft 21 causes the transmission rod 11 spline-connected thereto to rotate accordingly, ensuring the stability of power transmission. The process of resetting the spline shaft 21 and the extension tube 23 refers to the above steps;

[0037] by Figure 2For reference, when the transmission rod 11 drives the transmission gear shaft 15 to rotate clockwise through the bevel gear set, the double-track arc rack 31 and the single-track arc rack 32 rotate counterclockwise, and the wedge block 33 rotates counterclockwise following the single-track arc rack 32. When the wedge block 33 contacts the triangular block 101, the triangular block 101 restricts the wedge block 33 and the single-track arc rack 32 from continuing to rotate. At this time, the double-track arc rack 31 continues to rotate, and the single-track arc rack 32 slides on the double-track arc rack 31. The arc guide rod 34 inserts into the single-track arc rack. The annular return spring 35 is compressed in the rack 32. When the double-track arc rack 31 and the single-track arc rack 32 overlap, the gap on the front side of the installation housing 1 is large enough. The staff lifts the sleeve 12 and aligns the gap with the wire. After the wire enters the installation housing 1, the power source is controlled to rotate in the opposite direction, so that the double-track arc rack 31 and the single-track arc rack 32 rotate clockwise. At this time, the compressed annular return spring 35 presses against the single-track arc rack 32, and then the transmission gear shaft 15 first drives the double-track arc rack 31 to rotate clockwise, and the arc guide The rod 34 gradually leaves the single-track arc rack 32, and then the annular return spring 35 rebounds, and the arc guide rod 34 pulls the single-track arc rack 32 to rotate. When the single-track arc rack 32 is engaged with the transmission gear shaft 15, the double-track arc rack 31 and the single-track arc rack 32 completely cover the wire, and then rotate clockwise. When the wedge block 33 passes through the triangular stopper 101, the inclined surface of the wedge block 33 contacts the inclined surface of the triangular stopper 101, and the triangular stopper 101 squeezes the wedge block 33 to slide in the single-track arc rack 32, compressing After the elastic member 3301 and the wedge block 33 pass through the triangular stopper 101, the elastic member 3301 rebounds, so that the triangular stopper 101 will not prevent the single-track arc-shaped rack 32 from rotating clockwise, so that the single-track arc-shaped rack 32 can rotate clockwise for a full circle, thereby driving the cutting assembly 4 to complete the long-distance stripping of the wire. After the stripping is completed, the double-track arc-shaped rack 31 and the single-track arc-shaped rack 32 are driven to rotate counterclockwise, and the double-track arc-shaped rack 31 and the single-track arc-shaped rack 32 overlap to form a gap, and the installation housing 1 is removed from the wire;

[0038] When the installation housing 1 forms a gap, the single-track connecting frame 41 and the double-track connecting frame 42 rotate with the single-track arc rack 32 and the double-track arc rack 31 respectively, and the single-track connecting frame 41 slides in the double-track connecting frame 42, so that the single-track connecting frame 41 and the double-track connecting frame 42 overlap and form a gap, which facilitates the wire to enter the installation housing 1. When the single-track connecting frame 41 rotates clockwise following the single-track arc rack 32, the cutting blade 45 is restricted by the internal torsion spring 44 and cannot rotate clockwise around the installation shaft 43, so that the cutting blade 45 follows the single-track connecting frame 41 to rotate around the wire, and the inclined cutting blade 45 will push the mounting housing 1 to move horizontally during the cutting process, so as to continuously cut the wire. After cutting a suitable distance, the double-track arc rack 31 and the single-track arc rack 32 rotate counterclockwise. At this time, the cutting blade 45 contacts the wire, and the wire squeezes the cutting blade 45 to rotate counterclockwise around the mounting shaft 43, twisting the torsion spring 44 to form a gap again. After detaching from the wire, the torsion spring 44 rebounds, and the cutting blade 45 rotates to reset;

[0039] When the monorail connecting frame 41 rotates clockwise, the bending block 52 is attached to the monorail connecting frame 41. When the monorail connecting frame 41 rotates counterclockwise, the cutting blade 45 rotates counterclockwise to pull the pull rope 51, and the pull rope 51 pulls the bending block 52 to rotate counterclockwise. At this time, the V-shaped cutting block 53 at the end of the bending block 52 protrudes from the arc surface inside the monorail connecting frame 41, and cuts off the peeled outer skin of the wire, thereby eliminating the need to manually cut off the outer skin. After the installation shell 1 is separated from the wire, the cutting blade 45 rotates to reset. After the bending block 52 has no tension, when the monorail connecting frame 41 rotates clockwise, it automatically fits the inner arc surface of the monorail connecting frame 41 and is slidably connected to the wire.

[0040] like Figure 4 and Figure 8 As shown, a lubricating pad 6 is also included. The double-track connecting frame 42 is connected with the lubricating pad 6. The lubricating pad 6 is squeezed and matched with the outer side of the single-track connecting frame 41. The lubricating pad 6 can store lubricating oil.

[0041] When the monorail connecting frame 41 is slidably connected with the double-rail connecting frame 42, the outer side of the monorail connecting frame 41 is aligned and squeezed when passing through the lubricating pad 6, and the lubricating oil extruded is smeared on the outer side of the monorail connecting frame 41, and then the lubricating oil can flow to the cutting blade 45, thereby lubricating the cutting blade 45 and ensuring the surface quality of the cutting blade 45.

[0042] like Figure 1 As shown, a lighting lamp 7 is also included, and the mounting housing 1 is mounted with the lighting lamp 7 .

[0043] If the wire is in an area with poor lighting, or the ambient light is poor, the lighting lamp 7 on the top of the installation housing 1 can be turned on before the operation to facilitate the connection between the installation housing 1 and the wire.

[0044] First, by connecting the power source to the spline shaft 21 and starting, the power is transmitted to the transmission rod 11 through the spline shaft 21, and then the transmission gear shaft 15 is driven to start clockwise rotation through the bevel gear set. The transmission gear shaft 15 then drives the double-track arc rack 31 and the single-track arc rack 32 in the automatic clamping assembly 3 to rotate clockwise. The two are overlapped and separated at a specific position through the interaction of the arc guide rod 34, the wedge block 33 and the triangular block 101, forming a gap in the front of the installation shell 1, which is convenient for the installation shell 1 to be set on the wire. When adjusting the height of the installation shell 1, it is adjusted by loosening the fixing screw 22 and sliding the extension tube 23 up and down. The insulating rubber sleeve 24 increases friction and ensures safety, and then tighten the fixing screw 22 to fix the position. Then, the power source is controlled to drive the transmission gear shaft 15 to rotate counterclockwise, and the double-track arc rack 31 and the single-track arc rack 32 rotate clockwise. Through the continuous driving of the transmission gear shaft 15, the automatic clamping assembly 3 closes the gap, and the single-track connecting frame 41 and the double-track connecting frame 42 in the cutting assembly 4 follow, and the cutting blade 45 cuts the outer skin of the wire under the restriction of the torsion spring 44. After reaching the cutting length, the power source drives the transmission rod 11 in the reverse direction, so that the double-track arc rack 31 and the single-track arc rack 32 rotate counterclockwise, thereby restoring the gap and releasing the wire. At the same time, the single-track connecting frame 41 rotates counterclockwise, and the pull rope 51 pulls the bending block 52 to make the V-shaped cutting block 53 protrude and cut off the stripped outer skin, so that the installation shell 1 can be removed from the wire. In addition, the lubricating pad 6 provides lubrication when the single-track connecting frame 41 slides, and the lighting lamp 7 provides auxiliary lighting when the light is insufficient to ensure the smooth progress of the stripping operation.
