Description

Technical Field

[0001] The utility model relates to the technical field of cable sample preparation and peeling, in particular to an automatic end peeling device for cable sample preparation. Background Art

[0002] Cables are used to transmit electrical energy, signals, or data and are widely used in various fields, including power generation, communications, and electronic equipment. Cables can be classified into various types based on their purpose, structure, and material. During cable production, testing, research, and development, it is often necessary to prepare and process cable samples according to specific requirements and standards. This process is called cable sampling. The purpose of cable sampling is to conduct quality inspections, performance tests, and other experiments.

[0003] In the preparation of cable samples, an automatic end peeling device is required to remove the insulation layer or sheath layer of the cable sample to expose the internal conductor for further quality inspection, performance test or experiment. The working method of the existing automatic end peeling device for cable sample preparation is: first, place the cable sample to be peeled on the upper part of the operating table, and then fix the cable sample. After fixing the cable, adjust the tool position of the peeling device according to the specifications of the cable and the length to be peeled. Then, the tool begins to cut into the insulation layer of the cable sample, thereby completing the peeling operation of the cable sample.

[0004] Although the existing peeling device can complete the cable peeling operation, the fixing method is relatively simple and can only fix cables of the same specifications. It cannot adapt to cables of different specifications. As a result, if cables of various specifications need to be processed, different peeling devices must be used, or the clamps must be replaced frequently, which increases the workload and complexity and reduces the practicality of the automatic end peeling device for cable sample preparation.

The auxiliary wheels 15 are provided to facilitate the movement of the cable. The upper two sides of the mounting plate 5 are fixedly connected to a cross bar 11, and the two rotating plates 10 are rotatably connected to the outside of the two cross bars 11. The right side of the outside of the operating table 2 is fixedly connected to a mounting block 19, and the inside of the mounting block 19 is fixedly connected on both sides. The second electric push rod 20, the output ends of the two second electric push rods 20 are fixedly connected to a U-shaped block 21, the middle of the two U-shaped blocks 21 are installed with an arc cutter 22, and the interior of the two U-shaped blocks 21 is provided with a replacement component 25, the replacement component 25 is used to replace the arc cutter, the upper part of the mounting plate 5 is provided with a slide groove 9, the slider 8 is slidably connected to the inside of the slide groove 9, the upper part of the mounting plate 5 is fixedly connected to the mounting bracket 16, and the first electric push rod 17 is fixedly connected to the middle of the mounting bracket 16. 7 The output end is fixedly connected with a push plate 18. By starting the first electric push rod 17 and moving the push plate 18 fixed at the output end, the cable is moved. The front side of the mounting block 19 is fixedly connected with a scale plate 23. By setting the scale plate 23, the scale plate 23 provides clear scale marks, which can intuitively display the moving distance of the cable. The right side of the upper part of the operating table 2 is slidably connected with a collection box 3. The collection box 3 is convenient for collecting the peeled cable sheath. The two sides of the collection box 3 are fixedly connected with handles 4. The collection box 3 is convenient for moving.

[0027] Specifically, when fixing cables of different sizes, first, place the cable sample in the middle of the two arc-shaped clamping plates 14, then start the cylinder 6. The start of the cylinder 6 causes the moving block 7 at its output end to start to retract. During the retraction of the moving block 7, it drives the rotating plates 10 connected to the rotation on both sides of the outside to move together. Since the rotating plate 10 is connected to the two cross bars 11 through rotation, the retraction of the moving block 7 will cause the rotating plate 10 to rotate outside the two cross bars 11. While the two rotating plates 10 rotate, the two clamping blocks 13 connected to the top rotation will also move relative to each other outside the protrusion 12 as the rotating plate 10 rotates. When the two clamping blocks 13 move relative to each other, they drive the two arc-shaped clamping plates 14 fixed on the upper part to move relative to each other. The relative movement of the two arc-shaped clamping plates 14 will further drive the auxiliary wheels 15 installed inside to move relative to each other. These auxiliary wheels 15 are installed inside the arc-shaped clamping plates 14, which can be used for With flexible contact with the outer surface of the cable, as the arc-shaped clamping plate 14 and the auxiliary wheel 15 move, the auxiliary wheels 15 on both sides fit tightly against the outer surface of the cable, thereby completing the fixation of cables of different sizes and adapting to cables of different diameters and types. There is no need to frequently replace equipment or clamps, which improves the practicality of the device. When peeling the cable end, by starting the first electric push rod 17, the first electric push rod 17 moves with the push plate 18 fixed at the output end, and the push plate 18 moves to push the cable to move. With the cooperation of the auxiliary wheel 15, the cable passes through the middle of the mounting block 19. When the end of the cable leaks out, by starting the two second electric push rods 20, the two second electric push rods 20 move relative to each other with the two U-shaped blocks 21 fixed at the output end. The relative movement of the two U-shaped blocks 21 drives the two internally installed arc-shaped cutters 22 to move relative to each other. The operation of peeling the cable end can be completed by the relative movement of the two arc-shaped cutters 22.

[0028] Reference Figure 4 and Figure 5, the replacement component 25 includes a fixing rod 2501, which is fixedly connected to the inside of the U-shaped block 21. The U-shaped block 21 is provided to facilitate fixing the fixing rod 2501. Sliding blocks 2502 are slidably connected to both sides of the outside of the fixing rod 2501. The fixing rod 2501 plays a guiding role for the two sliding blocks 2502. Reset springs 2504 are provided on the outside of the two sliding blocks 2502. The two reset springs 2504 are sleeved on the outside of the fixing rod 2501. The main function of the reset spring 2504 is to provide a return force. When the external force pushes the sliding block 2502 to move, the reset spring 2504 will automatically bounce the sliding block 2502 back to its initial position when the external force disappears. The upper parts of the two sliding blocks 2502 are fixedly connected with handles 2503. By providing two handles 2503, it is convenient to During the use of the operator, the two sliding blocks 2502 are fixedly connected to the right side of the outside with an L-shaped rod 2505, and a first through hole 24 is provided inside the U-shaped block 21. The two handles 2503 are slidably connected to the inside of the first through hole 24. The first through hole 24 is provided to facilitate the movement of the handle 2503. Second through holes 26 are provided on both sides of the inside of the U-shaped block 21. The two L-shaped rods 2505 are slidably connected to the inside of the two second through holes 26. The second through holes 26 are provided to facilitate the movement of the L-shaped rods 2505. Sockets 27 are provided on both sides of the inside of the arc cutter 22. The two L-shaped rods 2505 are plugged into the two sockets 27, which improves the connection stability between the L-shaped rod 2505 and the arc cutter 22. After the L-shaped rod 2505 is inserted into the socket 27, it can effectively prevent the tool from shaking or loosening during use.

[0029] Specifically, when the curved cutter 22 needs to be replaced, the operator first needs to move the handles 2503 to both sides. The movement of the two handles 2503 drives the two sliding blocks 2502 fixed at the lower part thereof to slide toward the two sides of the fixed rod 2501. As the two sliding blocks 2502 move, the two return springs 2504 externally sleeved on both sides of the fixed rod 2501 are squeezed outward by the sliding blocks 2502, which causes the return springs 2504 to be deformed under the force. As the sliding blocks 2502 continue to move, they drive the two L-shaped plug rods 2505 fixed on the right side of the outside to move synchronously. The movement of the L-shaped plug rods 2505 causes them to gradually disengage from the inside of the insertion hole 27 of the curved cutter 22, releasing the fixing and limiting effect of the L-shaped plug rods 2505 on the curved cutter 22. At this time, the curved cutter 22 will no longer be fixed and can be removed from the U-shaped block 2 1, and after taking out the old curved cutter 22, when installing the new curved cutter 22, the new curved cutter 22 is placed in the middle of the U-shaped block 21, so that the sockets 27 on both sides of the curved cutter 22 are aligned with the two L-shaped rods 2505. After confirming that the position is correct, the operator releases the two grips 2503. At this time, the elastic potential energy accumulated by the two reset springs 2504 during the previous squeezing begins to be released, generating a reaction force, pushing the two sliding blocks 2502 back to the initial position. Under the action of the reset springs 2504, the two L-shaped rods 2505 are pushed into the sockets 27 of the curved cutter 22, and the curved cutter 22 is firmly fixed on the U-shaped block 21 again, so that the operator can quickly replace the tool, ensure that the curved cutter 22 always remains sharp, ensure the accuracy and quality of cable stripping, and ensure the consistency of the stripping effect.

[0030] Working principle: when it is necessary to fix cable samples of different sizes, first, place the cable sample in the middle of the two arc-shaped clamping plates 14, and then, start the cylinder 6, the cylinder 6 causes the moving block 7 fixed at the output end to retract, and the moving block 7 retracts and causes the rotating plates 10 connected on both sides to rotate on the outside of the two cross bars 11, and when the two rotating plates 10 rotate, the two clamping blocks 13 connected on the top to move relative to each other on the outside of the protrusion 12, and when the two clamping blocks 13 move relative to each other, the two arc-shaped clamping plates 14 fixed on the upper part move relative to each other, and the two arc-shaped clamping plates 14 move relative to each other, causing the auxiliary wheels 15 installed inside to move relative to each other, and the auxiliary wheels 15 on both sides contact the outside of the cable to complete the fixing of cables of different sizes, so that the device is convenient for fixing cables of different sizes, so that the device can adapt to cables of different diameters and types, without the need to frequently replace equipment or clamps, thereby improving the practicality of the device, and then, when it is necessary to replace the arc-shaped cutter 22, first, move the handles 2503 to both sides, and the two handles 2503 move the two fixed at the lower part The sliding blocks 2502 move toward the sides of the fixed rod 2501. When the two sliding blocks 2502 move, they squeeze the two return springs 2504 on both sides of the fixed rod 2501, causing the two return springs 2504 to deform under the force. Then, when the two sliding blocks 2502 move, they move the two L-shaped rods 2505 fixed on the right side of the outside synchronously, so that the two L-shaped rods 2505 are separated from the inside of the two insertion holes 27, thereby releasing the limit on the arc cutter 22, so that the arc cutter 22 can be removed from the U-shaped block 21. 2505 , and then, after releasing the two handles 2503, the two L-shaped rods 2505 are inserted into the two sockets 27 under the reaction force of the two reset springs 2504. This makes it easy to replace the curved cutter 22 of the peeling device, ensure that the curved cutter 22 always remains sharp, ensure the accuracy and quality of cable peeling, and ensure the best peeling effect.
