Description

Technical Field

[0001] This invention belongs to the field of cable stripping technology, specifically relating to an adaptive cable stripping tool. Background Technology

[0002] In the process of cable splicing, the removal of the insulated conductor sheath, or insulation, is a crucial step in the wire stripping and splicing process. Existing cable stripping methods are divided into manual and automated methods. When manually performing live-line work using insulated boom trucks or platforms, not only do workers directly contact live conductors, increasing safety risks, but the stripping process is also difficult, involves many steps, and is inefficient. Furthermore, the working environment is easily affected by local conditions. Automated stripping is gradually replacing manual methods. An automated stripping structure is described in Chinese Patent Publication No. CN109119946A, entitled "An Electric Cable Stripping Module." During operation, a drive unit rotates the stripping section, achieving a rotary stripping effect relative to the cable. While this type of automated cable stripping structure offers advantages such as high efficiency and low labor intensity, it still presents the following problems: Regarding the drive unit, to ensure radial cable insertion, the main gear needs to be designed as an open-end gear to allow the cable to be inserted into the main gear along its opening and achieve coaxial installation relative to the stripping section. However, during operation, the main gear needs to rotate to drive the stripping section to rotate coaxially. Therefore, an additional drive wheel is required to mesh with the main gear and drive its rotation. In this case, the main gear needs to rotate and also has an opening. This means that when a single drive wheel engages, it may disengage just as it reaches the opening of the main gear, leading to power transmission interruption and ultimately halting the operation. Therefore, existing solutions often employ several drive wheels arranged circumferentially around the main gear and meshing with it individually, ensuring that at least one drive wheel can transmit power to the main gear at any given time. The layout of multiple drive wheels obviously increases the overall assembly volume of the module, making it more complex, the transmission system larger, and the weight heavier, which is not conducive to use in cable stripping applications requiring high-altitude operations. On the other hand, since the insulation is usually made of high-strength polyethylene material, with very large thickness and hardness, the cutter needs not only an appropriate cutting depth but also an angled cutting angle to achieve reliable insulation removal. Existing stripping structures often neglect the adjustment of the cutting angle and focus on controlling the cutting depth, resulting in many examples of vertical cutting, such as the "automatic cable and wire stripping tool" disclosed in Chinese patent document CN202997432U. Obviously, relying solely on the vertical cutting method always presents a significant problem in terms of load-bearing capacity; if the insulation of the cable to be stripped is of high hardness, the cutter may even bend or break, causing many problems in actual operation.Finally, considering the power transmission issue, the current cable stripper uses a separate battery for both the cutting and clamping components, and even the cutting and clamping components use different batteries. The drive module where the opening wheel is located must also have a separate battery. This results in the entire stripper containing multiple battery packs that need to be disassembled, which is not only very inconvenient to install and remove, but also requires multiple charging ports for charging during online charging. This issue urgently needs to be addressed. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an adaptive cable stripping tool that has the advantages of compact structure, light weight and small size, and can achieve continuous operation of the cutting component and clamping component by relying on only a single drive wheel at the drive module.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An adaptive cable stripping tool includes a drive module, an open wheel at the drive module, a rotary module fixed on the open wheel for coaxial rotation around the cable, and a clamping component for centering and clamping the cable and a cutting component for cutting the cable insulation. The tool is characterized in that: a closed chain block is provided at the opening to avoid the cable installation path when open; when the closed chain block closes the opening, the outer edge of the closed chain block and the outer edge of the open wheel together form a circular transmission surface of the drive wheel at the power connection drive source.

[0006] Preferably, the closed chain block is hinged to the opening via an open hinge seat, and the hinge axis of the open hinge seat is parallel to the axis of the open wheel; in the rotation direction of the open wheel during peeling, the opening end of the opening located in this rotation direction is the front groove end, and the open hinge seat is installed at the front groove end.

[0007] Preferably, the open wheel is mounted on a mounting base plate, which includes a front base plate and a rear base plate. After the front base plate and the rear base plate are axially fitted together, they are enclosed by recessed receiving holes located on adjacent surfaces of the front base plate and the rear base plate to form a receiving cavity for receiving the open wheel. The front groove of the front base plate constitutes a contact surface for abutting the closed chain block, thereby pushing the closed chain block to produce a hinged closing action.

[0008] Preferably, the drive source is mounted on the rear base plate, and the drive source includes a single drive wheel driven by a drive motor. The teeth of the drive wheel are engaged with the circular transmission surface formed by the open wheel and the closed chain block.

[0009] Preferably, the other end of the closed chain block relative to the hinge end is the overlapping end. The overlapping end has a two-stage stepped structure, and the stepped surface of the overlapping end is perpendicular to the axis of the open wheel. The opening end of the opening that is used to fit the overlapping end has a stepped structure that matches the shape of the overlapping end.

[0010] Preferably, magnets are arranged at the closed chain block and / or the open wheel and / or the mounting base, so that a magnetic attraction is formed between the closed chain block and the open wheel and / or between the closed chain block and the mounting base.

[0011] Preferably, the drive module further includes a spring connector mounted on the front substrate for electrically connecting the main battery, and a contact patch is arranged on the moving surface of the clamping assembly facing the front substrate; in the cross-section of the vertical cable axis, the spring connector and the contact patch are located on the same circle with the cable axis as the center.

[0012] Preferably, the clamping assembly and the cutting assembly share a set of auxiliary batteries; a Hall sensor that avoids the mounting position of the spring connector is also arranged on the front substrate, and a magnetic block is arranged on the moving surface of the clamping assembly; in the cross-section perpendicular to the cable axis, the Hall sensor and the magnetic block are located on the same circle with the cable axis as the center.

[0013] Preferably, the cutting assembly includes a tool feed holder and a rocker arm hinged to the tool feed holder via a lower hinge seat, the axis of the lower hinge seat being parallel to the cable axis; a tool feed power source is provided at the rear end of the rocker arm for driving the rocker arm to generate a hinged swinging motion around the lower hinge seat; the tool feed power source includes a tool feed screw rotatably fitted to the tool feed holder, the tool feed screw being driven by a tool feed motor to generate a rotary motion; a tool feed slider is threaded onto the tool feed screw, a locating pin is horizontally protruding at the tool feed slider, and an oblong hole with the hole's length direction parallel to the length direction of the rocker arm is arranged at the rear end of the rocker arm, the locating pin passing through the oblong hole to form a sliding guide fit; the front end of the rocker arm constitutes a peeling end for mounting the tool.

[0014] Preferably, the clamping assembly includes a mounting frame fixed to the open wheel, a bidirectional lead screw in a simple beam-like rotatable configuration at the mounting frame, one end of the bidirectional lead screw being connected to a clamping motor via a gear set; a set of clamping blocks are threaded onto two threaded sections of the bidirectional lead screw; a guide rod in a simple beam-like configuration is provided at the mounting frame, the axis of the guide rod being parallel to the bidirectional lead screw, and a slide rail guiding engagement is formed between the clamping blocks and the guide rod; the clamping openings of both sets of clamping blocks are V-grooves shaped to facilitate cable centering.

[0015] The beneficial effects of this invention are as follows:

[0016] 1) Based on the above solution, this invention, grounded in a cable stripping system, incorporates a closed chain block, similar to a filler block, at the opening of the open wheel. By changing the opening and closing states of the closed chain block, the open and closed states of the opening can be adjusted online. When the opening is open, the cable can be inserted normally; when the opening is closed by the closed chain block, the open wheel and the closed chain block form a complete circle, facilitating the driving wheel's rotation. Due to this complete circle structure, taking gear meshing as an example, it essentially becomes a simple full-circumferential meshing between the driving wheel and the complete circle structure. Therefore, the problem of tooth disengagement inherent in traditional open wheels is eliminated, and even a single driving wheel can achieve reliable continuous drive throughout the entire process. The overall structure is also simpler, lighter, and more compact.

[0017] 2) As mentioned above, the closed chain block can be inserted later, such as by using a robotic arm or manual assistance from above; alternatively, it can be guided by a sliding groove, where the closed chain block is installed at one end of the opening of the open wheel. In the open state, the closed chain block is hidden at that end, while in the closed state, it slides directly along the groove to the other end, thus achieving a closing effect. This invention provides the simplest operating method, namely, using a hinged connection to achieve bridging.

[0018] 3) Furthermore, when hinged, the open hinge seat is located at the front groove end of the opening. That is, when the opening wheel rotates, it can automatically press the closing chain block to the other end of the opening by relying on the side components such as the mounting base plate, thereby completing the automatic closing action. The operation efficiency is higher and the usage process is more convenient and flexible. Of course, the active closing process of the closing chain block can also be completed by manual or robotic arm and other methods.

[0019] 4) Furthermore, to prevent the closed chain block from wobbling during the movement of the invention when it is opened, magnets can be placed on the closed chain block, the open wheel, and even the mounting base. When the open wheel is opened, the two magnets or the magnet and the iron block attract each other, preventing the closed chain block from wobbling. Of course, the above structure also ensures that the closed chain block will not be thrown off when rotating in the closed state, achieving multiple benefits.

[0020] 5) As mentioned above, this invention can achieve full power transmission using a minimum of one drive wheel; of course, using more drive wheels regardless of cost will not affect power transmission, only lower the cost-effectiveness. The structure of this invention is lighter and more compact, and can be driven by a single drive wheel, which is one of the highlights of this invention.

[0021] 6) For the engagement relationship between the circular structure formed by the open wheel and the closed chain block and the drive wheel, gear meshing is the most preferred method. Of course, other power transmission methods such as infinite friction or even rack and pinion transmission can also be used. In other words, the type of drive source should be selected according to the site conditions, so as not to affect the power transmission effect of the aforementioned circular structure as the driven wheel.

[0022] 7) This invention abandons the traditional vertical feed method and instead adopts a swing arm driven by a feed power source, in conjunction with a lower hinge seat, to achieve a swing-type feed effect for the tool. In actual operation, the cutting edge of the tool does not contact the cable. After the cable is clamped, the tool retracts under the swing action of the swing arm, driven by the feed power source, until the cutting edge contacts the cable, achieving online feed operation. Even during stripping, the feed power source can be controlled to further increase the feed depth according to the site conditions. This means that the online swing-type adjustment function of the feed depth can be realized in real time according to the current feed depth, thereby achieving a stable cutting effect on the cable insulation. It has the advantages of compact structure and flexible and convenient use.

[0023] Furthermore, the feed power source can be a cam-driven method, a linear stroke drive method, etc.; specifically, a linear stroke drive can be driven by a piston cylinder, a crank-slider mechanism, or various other drive structures. This invention preferably employs a lead screw-slider mechanism, which utilizes the self-locking property of the lead screw-slider mechanism to achieve adjustment of the feed amount and ensure a constant cutting edge position after adjustment, thus guaranteeing cutting quality. In addition, the lead screw-slider mechanism, the rocker arm, and even the lower hinge seat and feed post together form a triangular stabilization system, greatly improving the load-bearing capacity of the entire device and further ensuring stable cutting.

[0024] 8) Based on the above structure, this invention also provides a specific clamping assembly. The clamping assembly uses a guide rod as a guide element and a bidirectional lead screw as a power element, thereby achieving the mutual facing and separating movements of the two sets of clamping blocks. When the two sets of clamping blocks move towards each other, their V-shaped clamps ensure the cable is gripped and centered. Similarly, when the two sets of clamping blocks separate, the cable can be released simultaneously, making it very convenient to use. Furthermore, thanks to the gear set, the auxiliary battery and clamping motor can be moved to the side, making the entire assembly more compact and effectively improving its portability and operability.

[0047] For ease of understanding, this section combines... Figure 1-17 The specific structure and operation of the present invention are further described below:

[0048] like Figure 1-2 As shown, in actual assembly, the present invention is composed of a drive module 10 and a rotary module driven by the driven module 10 to perform clamping and circumferential cutting actions around cable a. The rotary module is further subdivided into a cutting component 20 and a clamping component 30, thereby achieving the effect of online stripping of the insulation at cable a.

[0049] During operation, the machine has two power supply modules: a main battery 15 and a secondary battery. The cutting assembly 20 and the clamping assembly 30 are powered by the secondary battery, while the drive module 10 is powered by the main battery 15. Both batteries can be designed as pluggable, detachable structures. When the rotary module moves to a specific position, the drive module 10 can charge the secondary battery at the rotary module.

[0050] More specifically as follows:

[0051] I. Drive Module 10

[0052] Taking gear meshing as an example, specifically the outer edges of the open wheel 13, the closed chain block 14, and the drive wheel 12b, all having toothed structures, and the various components forming gear meshing, the following detailed embodiment will be described:

[0053] Under the above premise, such as Figure 2-4 and Figure 11As shown, in this invention, a closed chain block 14 is hingedly mounted at the opening 13a of the open wheel 13 via an open hinge seat 14a. The closed chain block 14 can freely open and close around the open hinge seat 14a in the non-working state; in such a state... Figure 1-5 In the open state shown, cable a can be inserted into the space left inside the opening wheel 13, i.e., the slot of the opening 13a. After cable a is inserted into the slot of the opening 13a, the closing chain block 14 can be closed manually or by other active means such as a robotic arm. If the closing chain block 14 is not closed, during operation of this invention, the closing chain block 14 will be automatically pushed and closed by the mounting base 11 or other side-mounted components. The overlapping end 14b of the closing chain block 14 is magnetically attached to the opening wheel 13 or the mounting base 11 to ensure that it will not fall off during operation.

[0054] In reality, because power transmission lines are generally high above the ground, during lifting operations, the cable stripper is placed on cable a, making it difficult for a person to reach it and thus hindering the easy closure of the closing chain block 14. And because of this... Figure 2 The rear substrate 11b and front substrate 11a form a receiving cavity, thereby clamping the opening wheel 13 in the middle. At this time, the protruding part of the opening wheel 13, namely the arc-shaped protrusion 13b, can fit with the corresponding guide rings at the receiving countersunk holes of the rear substrate 11b and the front substrate 11a, so that the opening wheel 13 can rotate freely between the two substrates. Therefore, in the design, the pressing action of the mounting substrate 11 of the opening wheel 13 and the closing chain block 14 can be used to push the closing chain block 14 to close the opening 13a. In other words, when the closing chain block 14 is closed by the mounting substrate 11, the front substrate 11a can be used to push the closing chain block 14 located on the action path to produce a hinge action, thereby realizing the closing process. Preferably, a rounded corner can even be left at the initial contact point between the front substrate 11a and the closing chain block 14, so that when the closing chain block 14 moves to the position of the rounded corner, it is quickly squeezed to close the opening 13a.

[0055] When the closed chain block 14 is opened, to prevent it from wobbling during the movement of the cable stripper and affecting its movement to the working position, magnets can be provided on the closed chain block 14, the open wheel 13, and even the mounting base plate 11. When the open wheel 13 is open, the two magnets or the magnet and the iron block attract each other, preventing the closed chain block 14 from wobbling. At the same time, due to the presence of the magnets, the closed chain block 14 will not be thrown off when rotating in the closed state.

[0056] like Figure 3-4 As shown, the drive source 12 includes a drive motor 12a. The drive motor 12a reduces the speed through a reducer and then transmits the power to the drive wheel 12b. The drive wheel 12b outputs the power by engaging with the open wheel 13.

[0057] Furthermore, such as Figure 3-4 As shown, the present invention also arranges a spring connector 17 electrically connected to the main battery 15 on the front substrate 11a. When the spring connector 17 contacts the contact patch on the clamping assembly 30, it can charge the clamping assembly 30, eliminating the need to replace multiple battery sets; similarly, it can also provide online high-altitude power replenishment for the cutting assembly 20 or direct charging via a single charging port when idle. Of course, in the case of the present invention, it can be used for direct charging via a charging connector, or continuous operation can be achieved by replacing the main battery 15. When the work is finished, the present invention can also be used as follows: Figure 4 and Figure 10 The Hall sensor 16 shown senses the position of the magnetic block on the clamping assembly 30, enabling automatic reset and recharging. The entire operation is controlled by a microcontroller. Furthermore, the circuit board can be custom-shaped to fit the internal space of the housing, meeting both usability and aesthetic requirements.

[0058] II. Cutting assembly 20

[0059] like Figure 1-2 , Figure 5-10 and Figure 12-14 As shown, the specific implementation structure of the cutting assembly 20 includes a feed post 21 as the main carrier, on which a feed power source 24, a swing arm 23, and a cutting tool 25 are mounted. During operation, the cutting tool 25 is mounted at the front end of the swing arm 23, and the rear end is hinged to the feed power source 24. The middle section of the swing arm 23 is hinged to the feed post 21 via a lower hinge seat 22. Thus, driven by the feed power source 24, the swing arm 23 swings, thereby achieving the following... Figure 10 and Figure 14 The cutter 25 shown demonstrates the fit and even cutting-in effect of the cable a relative to it.

[0060] Furthermore, the feed power source 24 includes a feed motor 24b, a feed screw 24a, and a feed slider 24c. The feed screw 24a is simply supported in a beam shape and rotates on the feed holder 21, and the feed slider 24c is fitted onto the feed screw 24a. The output shaft of the feed motor 24b is connected to the feed screw 24a via a coupling. During operation, the feed motor 24b causes the feed slider 24c to perform a linear reciprocating motion; as the feed slider 24c reciprocates, the locating pins 24d on both sides of the feed slider 24c engage with the oblong holes 23a, allowing it to... Figure 13-14 The drive lever 23 shown generates a swinging motion.

[0061] exist Figure 14 In the middle, the limit switch 26 is installed on the feed holder 21 or at the lower hinge seat 22. When the positioning pin 24d on the feed slider 24c moves to the designated position, the positioning pin 24d triggers the limit switch 26, and the feed motor 24b stops working. At the same time, below the lower hinge seat 22, it is possible to... Figure 12and Figure 14 The mounting base for the cutting sensors shown contains several built-in cutting sensors 27. These sensors can detect the size of cable a, and the feed rate of the tool 25 can be controlled based on the corresponding cable specifications. Alternatively, the distance between cable a and the tool 25 can be detected, and the feed rate of the tool 25 can be controlled by analyzing the data from the cutting sensors 27, thus achieving online adjustment of the feed rate for cables a of different sizes.

[0062] Of course, in Figure 1-2 In the structure shown, the present invention also includes a light shield 28 to provide shielding and protection.

[0063] III. Clamping Components 30

[0064] Figure 2-3 and Figure 15-17 The document discloses an embodiment diagram of the corresponding clamping component 30.

[0065] In the design, the clamping assembly 30 is fixed to the open wheel 13 of the drive module 10. The open wheel 13 can rotate at one end of the drive module 10, thereby driving the clamping assembly 30 and the clamping assembly 30 to rotate together. The clamping assembly 30 can fix the entire machine to the cable a with the clamping block 34. The clamping block 34 has a C-shaped structure, which can automatically center itself and thus adapt to cables of different sizes. In addition, the clamping block 34 is provided with a guide groove, and the rotation of the clamping block 34 enables the entire machine to achieve automatic feeding movement along the axial direction of the cable a.

[0066] More specifically, during operation, the clamping motor connects to the gear set 33 via a reducer, which independently transmits power to the bidirectional lead screw 32. Furthermore, the gear set 33 includes three sets of power gears that mesh with each other to achieve power transmission while ensuring a compact overall size. The arrangement of the power gears is as follows... Figure 15-17 As shown. The bidirectional lead screw 32 has two symmetrical threads, which enable the two sets of clamping blocks 34 to move close to each other and away from each other along the axial direction of the bidirectional lead screw 32.

[0067] Furthermore, when the clamping block 34 moves to its maximum position, a photoelectric switch can be triggered, stopping the clamping motor and creating a limit. The entire clamping assembly 30 can be connected to the rotating connecting block via a rotating side plate; the rotating side plate and the rotating connecting block together form a mounting bracket 31 that can be fixed to the open wheel 13.

[0068] During assembly, the cutting assembly 20 and the clamping assembly 30 can be connected together by adjusting the lateral pads, so that when the clamping block 34 moves, it can drive the cutting assembly 20 to move as a whole, ensuring that the cutting assembly 20 and the clamping block 34 are in a relatively stationary state. The guide rod 35 is used to guide the travel path of the two sets of clamping blocks 34.

[0069] During operation, the two sets of clamping blocks 34 can utilize the guide ribs on the V-groove surface at the clamping port to enable the entire machine to move along the cable axis during movement, thereby achieving the axial stripping effect.

[0070] As a whole component, the actual working process of this invention is as follows:

[0071] S1) Initial state is Figure 5 As shown, at this time, the opening 13a of the open wheel 13 naturally faces downward.

[0072] S2) Insert the cable into the opening 13a, such as Figure 6 As shown.

[0073] S3) such as Figure 7 As shown, the closed chain block 14 is closed, at which point the closed chain block 14 magnetically attracts and closes the opening 13a of the open wheel 13; subsequently, as... Figure 8 As shown, clamping blocks 34 begin to move in opposite directions and clamp cable a.

[0074] S4) Figure 9 In the middle, the tool 25 begins to move gradually until it reaches the cutting position.

[0075] S5) as Figure 10 As shown, the open wheel 13 starts to move and drives the rotary module to rotate, and the cutter 25 starts to cut the insulation.

[0076] S6) After the cutting is completed, the tool 25 cuts off the chips; then, each moving part returns to its initial position, and the tool 25 returns to its initial position; then, the closed chain block 14 opens, the clamping block 34 resets, and the stripped cable can be taken out, completing the entire stripping process of cable a.
