[0001] This utility model relates to the field of cable testing and inspection technology, specifically a robotic cable winding and torsion testing device. Background Technology

[0002] The robot cable winding and torsion test device is a device specifically designed to test the performance of robot cables under winding and torsion conditions. It is of great significance for ensuring the quality and performance of robot cables and promoting the development of robot technology.

[0003] Chinese patent publication number CN211292400U discloses a cable winding torsion test device. This prior art directly controls the operation of a stepper motor to drive the cable to twist during the test, and at the same time uses a proximity sensor to detect and count the number of twists of the cable, achieving good test results.

[0004] When the above-mentioned equipment performs a winding and torsion test on the cable, it directly clamps the cable. During the torsion test, the surface of the cable will deform to a certain extent as it twists, making the clamping position unstable. This may cause the clamped cable to loosen, thus interrupting the winding and torsion test. This not only affects the accuracy of the test data but also the testing efficiency of the equipment. Optimization and improvement are needed. Utility Model Content

[0005] The purpose of this invention is to provide a robotic cable winding and torsion testing device to solve the problem mentioned in the background art that the cable may be interrupted during the torsion test due to insufficient clamping, which affects the test efficiency.

[0007] The positioning and reinforcement component includes a twisting end clamp, which is connected to one side of the connecting frame and has a U-shaped groove inside. A clamping plate is provided on one side of the twisting end clamp. The positioning and reinforcement component is used for positioning and reinforcement of the test cable. The protection component includes a limiting slide frame, which is located in front of the top of the supporting base plate and has a protective plate at its top. The protection component is used for front-end protection during the test.

[0008] Preferably, both the upper and lower ends of the twisting end clamping block are connected to sliding connecting plates, and the inner side of the sliding connecting plate is connected to a sliding snap block.

[0012] Preferably, a slide rail is provided on the other side of the top of the support base plate, and a positioning slider is slidably connected to the top of the slide rail.

[0013] Preferably, one end of the positioning slider is connected to a telescopic rod, and one end of the telescopic rod is connected to a positioning clamp.

[0014] Preferably, a rubber pad is connected to the bottom end of the protective plate, and a side baffle is connected to the outer side of the protective plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention increases the fixing area of ​​the cable by bending the cable end through the U-shaped groove during positioning and clamping, and then stably clamping the two horizontally protruding sections of the cable. The bending also reduces the contact friction between the cable and the twisted end clamping block, thereby improving the stability of the cable fixing and ensuring the testing efficiency of the equipment.

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0025] like Figure 1 - Figure 4 As shown, this application provides a robot cable winding and torsion testing device, including: a support base plate 1, a connecting frame 2 is provided on one side of the top of the support base plate 1, and a servo motor 3 is connected to one end of the connecting frame 2;

[0026] Specifically, such as Figure 1 As shown, a slide rail 14 is provided on the other side of the top of the support base plate 1, and a positioning slider 15 is slidably connected to the top of the slide rail 14. One end of the positioning slider 15 is connected to a telescopic rod 16, and one end of the telescopic rod 16 is connected to a positioning clamping block 17. The positioning slider 15 is slidably positioned at the top of the slide rail 14, and then the positioning clamping block 17 is pushed by the telescopic rod 16 to adjust the position, so as to achieve the effect of clamping and positioning.

[0027] The positioning and reinforcement assembly includes a twisting end clamp 4, which is connected to one side of the connecting frame 2. The twisting end clamp 4 has a U-shaped groove 5 inside and a clamping plate 9 on one side. The positioning and reinforcement assembly is used for positioning and reinforcement of the test cable.

[0028] Specifically, such as Figure 2As shown, both the upper and lower ends of the twisting end clamping block 4 are connected to sliding connecting plates 6, and the inner side of the sliding connecting plate 6 is connected to a sliding snap block 7. The clamping plate 9 is connected to the inner side of the sliding snap block 7, and one side of the clamping plate 9 is connected to a positioning block 8. The sliding snap block 7 drives the clamping plate 9 to slide inside the sliding connecting plate 6. The groove inside the clamping plate 9 fits the cable and squeezes and positions it, achieving a stable clamping effect.

[0029] Specifically, such as Figure 3 As shown, a rotating top block 11 is connected to the inner side of the connecting frame 2. One end of the rotating top block 11 is connected to the rotating end of the servo motor 3. After the top block on the outer side of the rotating top block 11 rotates once, it will squeeze the elastic pressing plate 13 once, so as to achieve the effect of top counting.

[0030] Specifically, such as Figure 3 As shown, the top of the connecting frame 2 is connected to an adjustment frame 10, and the top of the adjustment frame 10 is connected to a display screen 12. An elastic compression plate 13 is connected to the inner side of the adjustment frame 10. The elastic compression plate 13 can move up and down inside the adjustment frame 10. The number of contactes is counted and displayed on the display screen 12.

[0031] The protective component includes a limiting slide frame 18, which is located at the top front of the support base plate 1, and a protective plate 19 is provided at the top of the limiting slide frame 18. The protective component is used for front-end protection during the test.

[0032] Specifically, such as Figure 4 As shown, a rubber pad 20 is connected to the bottom end of the protective plate 19, and a side baffle 21 is connected to the outer side of the protective plate 19. The protective plate 19 connected to the side baffle 21 can restrict the sliding inside the limiting slide frame 18, and the inner side can improve the stability of the equipment after movement by the squeezing of the rubber pad 20.

[0033] In this embodiment: when positioning and clamping the cable, the end of the cable is bent and passed through the U-shaped groove 5, and then the two horizontally protruding sections of the cable are stably clamped, thereby increasing the fixing area of ​​the cable when it is fixed. The bending setting also reduces the contact friction between the cable and the twisted end clamping block 4, thereby improving the stability of the cable when it is fixed and avoiding affecting the accuracy of the test data. During the experiment, the cable may fall off at one end under the action of torque. At this time, the transparent acrylic protective plate 19 that can be slidably adjusted is used to protect the front end of the worker.

[0034] The specific solution is as follows: When conducting a winding and twisting experiment on a robot cable, the cable is first cut to a suitable length, and then the end is inserted into the U-shaped groove 5 inside the twisting end clamp 4, allowing the end of the cable to be bent. At this time, the sliding snap block 7 drives the clamp 9 to slide inside the sliding connecting plate 6. The groove inside the clamp 9 fits the cable and squeezes and positions it, achieving a stable clamping effect. One end of the positioning clamp 17 is also provided with the same fixing structure. Then, the protective plate 19 is slid to the front of the operator for protection. The protective plate 19 has a certain positioning function through the squeezing of the rubber pad 20. After preparation, the servo motor 3 drives the rotating top block 11 and the cable to twist. The telescopic rod 16 moves in conjunction with the positioning clamp 17 to adapt to the cable twisting test adjustment. Then, after the top block outside the rotating top block 11 rotates once, it will squeeze the elastic squeezing plate 13 once. The elastic squeezing plate 13 can move up and down inside the adjustment frame 10. The number of contact is counted and displayed on the display screen 12 to intuitively display the experimental data.
