Description

Technical Field

[0001] This utility model relates to the field of cable processing technology, and in particular to a hydraulic cable cutting device for a vision positioning robot. Background Technology

[0002] Cables are a general term for optical cables, electrical cables, and various other types of cables. They are widely used in various fields of modern society. Their structure consists of a conductor, an insulation layer, a shielding layer, and a sheath layer. They are characterized by high power transmission, high voltage level, and good insulation performance, and are mainly used for power transmission and distribution in power systems.

[0003] The main function of a cable cutting device is to cut cables. Whether in construction scenarios in the power and communication industries or in the field of waste cable recycling, cables are the objects of cable cutting devices. Depending on the material, diameter, and quantity of the cables, cable cutting devices need to have corresponding cutting capabilities and adaptability to ensure that they can complete the cutting task efficiently and accurately.

[0004] Visual positioning robots with hydraulic cable cutting capabilities can achieve high-precision cable cutting, with operating speeds far exceeding manual operation, significantly improving work efficiency. However, bent or tangled cables make it difficult for the vision system to accurately determine their direction and endpoint positions. Furthermore, irregular cable placement, such as tilting or suspension, poses challenges to positioning, leading to discrepancies between visual positioning results and actual conditions. Existing technology involves designing specialized cable fixing devices to secure the cable before cutting, ensuring its stable position and posture. However, in practice, the fixing devices need to be adjusted according to different cable conditions and work requirements. The adjustment mechanisms of these devices are often inflexible or inconvenient, making quick and accurate adjustments difficult. For example, adjusting the angle of the fixing device requires loosening multiple screws for manual adjustment, followed by retightening, a complex process that makes it difficult to guarantee adjustment accuracy.

[0038] Working principle: First, the cable is placed in the clamping block 16. The electric push rod 6 pushes the U-shaped block 7 to move. The U-shaped block 7 drives the turntable 9 on the front side of the connecting block 8 to rotate. The turntable 9 causes the six sliding columns 12 to slide simultaneously in the first slide groove 11. A slider 14 is fixed on the right side of the sliding column 12. Because of the rotation of the turntable 9, the six sliders 14 slide simultaneously in the third slide groove 15 in the disc 10. A clamping block 16 is fixed on the right side of the slider 14. By sliding the clamping block 16 inward simultaneously, it can adaptively adjust according to the different shapes and sizes of the cable, so that the cable is fixed before cutting, ensuring its position and posture are stable.

[0039] The motor 201 inside the base plate 1 is started. The motor 201 drives the rotating shaft 202 to rotate. The rotating shaft 202 drives the two bevel gears 203 to rotate. The bevel gears 203 synchronously drive the threaded rod 205 on the left bevel gear 204 to rotate on the limiting block 206 in the slide groove 17. The threaded rod 205 drives the threaded block 207 to rotate. Since the threaded block 207 is fixed on both sides of the bracket 208, the bracket 208 moves left and right under the action of the threaded block 207. When it is necessary to cut the cable at different positions, the cutter 210 at the output end of the hydraulic rod 209 is moved by the bracket 208, which can quickly move the cutting cutter 210 to the target position.
