Description

Technical Field

[0001] This invention belongs to the technical field of cable stripping devices, specifically relating to an adjustable limiting device and a stripping method for assisting wire strippers. Background Technology

[0002] Before connecting and using cables, the outer sheath of the cable ends needs to be stripped. In existing technology, wire strippers are typically used to directly strip the cable ends. However, these wire strippers only limit the radial direction of the cable (by limiting the cable diameter through locating holes), but do not limit the axial length. The stripped length at the cable ends is usually determined visually by the operator. However, the stripped length often varies for different cable specifications, and in high-precision wiring environments, the accuracy of the stripped length is crucial. Relying on visual inspection for stripping can lead to insufficient or redundant stripped sections at the cable ends.

[0003] Therefore, in order to address the problem that existing handheld wire strippers cannot accurately strip cables of various specifications at once to meet their respective stripping length requirements, this invention discloses an adjustable limiting device and a stripping method to assist wire strippers in stripping. Summary of the Invention

[0004] This invention discloses an adjustable limiting device and a stripping method for assisting wire strippers in stripping wires. It can precisely strip several cables of different specifications at one time according to their respective stripping length requirements, which not only improves the stripping efficiency of cables, but also ensures the accuracy of the stripping length requirements.

[0005] This invention is achieved through the following technical solution: An adjustable limiting device for assisting wire strippers in stripping wires includes a support frame with a U-shaped opening. Several cable limiting grooves of different specifications are linearly arranged on the lower side of the U-shaped opening. A limiting slider is slidably installed inside each cable limiting groove. A linear drive device is provided between the bottom of the limiting slider and the bottom of the cable limiting groove, driving the limiting slider to slide along the cable limiting groove. A limiting abutment is provided at the first end of the limiting slider, and a guide moving part is provided at the second end of the limiting slider. The end face of the limiting abutment abuts against the end of the cable, and the guide moving part is slidably connected to the cable limiting groove.

[0006] To better realize the present invention, the first end of the cable limiting groove is provided with a U-shaped groove, the second end of the cable limiting groove is provided with a support groove, the linear drive device is disposed inside the support groove, the limiting abutment part is slidably disposed inside the U-shaped groove, and the width of the U-shaped groove is set to correspond to the cable diameter; the guide moving part is slidably disposed inside the support groove, and the guide moving part is connected to the drive end of the linear drive device.

[0007] To better realize the present invention, the first end of the limiting slider is provided with a first support block, the second end of the limiting slider is provided with a second support block, the first support block is slidably connected to the U-shaped groove, the second support block is slidably connected to the support groove, and one side of the second support block is connected to the driving end of the linear drive device.

[0008] To better realize the present invention, the linear drive device further includes a screw, a first limiting hole is provided at one end of the support groove near the U-shaped groove, a limiting bracket is fitted at the other end of the support groove away from the U-shaped groove, a second limiting hole is provided on the limiting bracket, a first end of the screw is rotatably connected to the first limiting hole, and a second end of the screw is rotatably connected to the second limiting hole.

[0009] To better realize the present invention, a slot is further formed between the second ends of adjacent limiting sliders, and a locking block corresponding to the slot is provided on the side of the limiting bracket near the limiting slider.

[0010] To better realize the present invention, the second end of the screw extends to the outside of the second limiting hole, and a slot is provided on the end face of the second end of the screw.

[0011] To better realize the present invention, a rod-shaped linear displacement sensor is further provided inside the support groove, and one end of the rod-shaped linear displacement sensor is connected to one side of the second support block.

[0012] To better realize the present invention, the support frame is further provided with a threaded connection hole, which is connected to the wire stripper by a connecting bolt.

[0013] An adjustable limit stripping method for assisting wire strippers includes the following steps: Step 1: Fix the wire stripper to one side of the support frame, so that the stripping blade of the wire stripper is aligned with the cable limiting groove; Step 2: After passing the cable end through the limiting hole on the wire stripper, insert it into the cable limiting groove of the corresponding specification so that the cable end abuts against the limiting abutment part of the limiting slider.

Step 4: After locking the limit slider, use wire strippers to strip the cable. After the cable is stripped, use a linear drive device to drive the limit slider to slide back and reset.

[0014] Compared with the prior art, the present invention has the following advantages and beneficial effects: This invention features cable limiting grooves of varying widths on the lower side of the U-shaped opening of a support frame, corresponding to different cable diameters.

[0017] Example 1: This embodiment discloses an adjustable limiting device for assisting wire strippers in stripping wires, such as... Figures 1-3As shown, the device includes a support frame 1 with a U-shaped opening. Several cable limiting grooves 2 of different specifications are linearly arranged on the lower side of the U-shaped opening. Limiting sliders 3 are slidably installed inside the cable limiting grooves 2. A linear drive device 4 is provided between the bottom of the limiting slider 3 and the bottom of the cable limiting groove 2. The linear drive device 4 drives the limiting slider 3 to slide along the cable limiting groove 2. A limiting abutment is provided at the first end of the limiting slider 3, and a guide moving part is provided at the second end of the limiting slider 3. The end face of the limiting abutment abuts against the end of the cable, and the guide moving part is slidably connected to the cable limiting groove 2.

[0018] The cable limiting groove 2 is used to axially limit cables of corresponding specifications. The cable end is inserted into the cable limiting groove 2, so that the cable end abuts against the end face of the limiting slider 3, thereby achieving axial limiting of the cable. Simultaneously, the linear drive drill 4 drives the limiting slider 3 to slide along the cable limiting groove 2, thereby pushing the cable end to adjust the length of the cable end inserted into the cable limiting groove 2, thus adjusting the cable stripping length. After different specifications of cables have been adjusted according to their respective stripping length requirements, the outer sheath of the cable can be stripped using wire strippers. By setting different specifications of cable limiting grooves 2, and simultaneously using the linear drive device 4 to drive the limiting slider 3 at different positions to move different strokes, several cables of different specifications can be stripped at once.

[0019] Furthermore, such as Figure 3 As shown, the first end of the cable limiting groove 2 is provided with a U-shaped groove 21, and the second end of the cable limiting groove 2 is provided with a support groove 22. The linear drive device 4 is disposed inside the support groove 22. The limiting abutment part is slidably disposed inside the U-shaped groove 21, and the width of the U-shaped groove 21 corresponds to the cable diameter. The guide moving part is slidably disposed inside the support groove 22, and the guide moving part is connected to the drive end of the linear drive device 4. Figure 4 As shown, the first end of the limiting slider 3 is provided with a first support block 31, and the second end of the limiting slider 3 is provided with a second support block 32. The first support block 31 is slidably connected to the U-shaped groove 21, and the second support block 32 is slidably connected to the support groove 22. One side of the second support block 32 is connected to the driving end of the linear drive device 4.

[0020] The linear drive device 4 drives the second support block 32 to slide inside the support groove 22, which in turn drives the first support block 31 at the other end to slide inside the U-shaped groove 21. By pushing the end of the first support block 31 against the end of the cable, the depth of the cable into the U-shaped groove 21 is adjusted, that is, the stripping length of the cable is adjusted.

[0021] Furthermore, such as Figure 5 As shown, the linear drive device 4 includes a screw. A first limiting hole is provided at one end of the support groove 22 near the U-shaped groove 21. A limiting bracket 5 is fitted at the end of the support groove 22 away from the U-shaped groove 21. A second limiting hole is provided on the limiting bracket 5. The first end of the screw is rotatably connected to the first limiting hole, and the second end of the screw is rotatably connected to the second limiting hole. The second end of the screw extends outside the second limiting hole, and a slot 41 is provided on the end face of the second end of the screw.

[0022] Rotating the slot 41 with a flathead screwdriver causes the screw to rotate. The screw engages with the threaded hole at the bottom of the second support block 32, causing the second support block 32 to slide along the support groove 22. This ultimately causes the first support block 31 to slide along the U-shaped groove 21, pushing the end of the cable. After the screw stops rotating, a self-locking structure between the threads prevents the screw from continuing to rotate, thus locking the limit slider 3.

[0023] Furthermore, such as Figure 6 As shown, a groove is formed between the second ends of adjacent limiting sliders 3, and a locking block 51 corresponding to the groove is provided on the side of the limiting bracket 5 near the limiting slider 3. Through the engagement between the groove and the locking block 51, the limiting bracket 5 can be quickly installed on the second end of the screw.

[0024] Furthermore, a rod-shaped linear displacement sensor is installed inside the support groove 22, with one end of the rod-shaped linear displacement sensor connected to one side of the second support block 32. When the second support block 32 moves, it drives the measuring rod of the rod-shaped linear displacement sensor to move, thereby accurately reading the movement stroke of the cable end inside the U-shaped groove 21 through the rod-shaped linear displacement sensor, and thus accurately adjusting the stripping length of the cable.

[0025] Furthermore, the support frame 1 is provided with a threaded connection hole 11, which is connected to the wire stripper by a connecting bolt.

[0026] An adjustable limit stripping method for assisting wire strippers includes the following steps: Step 1: Fix the wire stripper to one side of the support frame 1, so that the stripping mouth of the wire stripper is aligned with the cable limiting groove 2. Step 2: After passing the cable end through the limiting hole on the wire stripper, insert it into the cable limiting groove 2 of the corresponding specification, so that the cable end abuts against the limiting abutment part of the limiting slider 3. Step 3: According to the required stripping length of different specifications of cables, the linear drive device 4 drives the limiting slider 3 to slide within the cable limiting groove 2 to limit the required stripping length of the cable in the cable limiting groove 2. Step 4: After locking the limit slider 3, the cable is stripped using wire strippers. After the cable is stripped, the limit slider 3 is driven to slide back to its original position by the linear drive device 4.

[0027] The rest of this embodiment is the same as that of Embodiment 1, so it will not be described again.

[0028] Example 2: This embodiment discloses an adjustable limiting device for assisting wire strippers in stripping wires. The contact plane of the support frame 1 matches and fits the shape of the wire stripper. Six sets of cable limiting grooves 2 are linearly arranged on the lower side of the U-shaped opening on the support frame 1. The width of the U-shaped groove 21 at the first end of the six sets of cable limiting grooves 2 corresponds to six types of cables with specifications of 16, 18, 20, 22, 24 and 26 respectively. A limiting slider 3 is slidably fitted inside each cable limiting groove 2.

[0029] By cooperating with the screw and threaded hole at the bottom of the limiting slider 3, the second support block 32 at the second end of the limiting slider 3 can slide along the support groove 22 when the screw is rotated, thereby causing the first support block 31 at the first end of the limiting slider 3 to slide along the U-shaped groove 21. The cable end inserted into the U-shaped groove 21 is pushed by the first support block 31, thereby limiting and adjusting the stripping length of the cable.

[0030] The rest of this embodiment is the same as that of Embodiment 1, so it will not be described again.

[0031] The above are preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
