Abstract
Description
Technical Field
[0001] This utility model relates to the field of robot connection cable technology, specifically a robot connection cable protection and reinforcement device. Background Technology
[0002] The primary function of industrial robot connectors is to provide power and data transmission, ensuring the normal operation of all components. Power connectors transmit power to critical components such as drive motors, sensors, and controllers, guaranteeing the robot's smooth operation. Data transmission connectors carry control signals and data, ensuring the robot's control system accurately receives and executes instructions, and relays data collected by sensors to the processing unit. Industrial robots perform complex movements such as rotation, extension, and transport during tasks. Therefore, the connectors must not only support power and data transmission but also withstand the tension, bending, and torsion caused by mechanical movement.
[0003] The above-mentioned utility model has the following problems:
[0004] 1. In the existing technology, the connection cable of the industrial robot needs to be bent constantly under the complex movement of the industrial robot. The connection cable of the existing technology has poor anti-bending effect, and there is no good protection effect when the connection cable of the industrial robot is collided.
[0005] Therefore, those skilled in the art have provided a robot connection line protection and reinforcement device to solve the problems mentioned in the background art. Utility Model Content
[0006] The purpose of this invention is to provide a robot connection cable protection and reinforcement device to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A robot connection cable protection and reinforcement device includes a fixed base, a connecting bending member, and an outer protective tube. A first rotating bearing is fixedly connected to the outer side of one end of the connecting bending member, and a base threaded connector is rotatably connected to the outer side of the first rotating bearing. The base threaded connector and the fixed base are threadedly connected to each other.
[0009] As a further embodiment of this utility model: a second rotating bearing is fixedly connected to the outer ends of both ends of the outer protective tube, and a threaded ring is rotatably connected to the outer ends of both sets of second rotating bearings.
[0010] As a further improvement of this utility model: the upper and lower ends of the inner sidewall of the outer protective tube are fixedly connected with tough rubber parts, and one end of each set of tough rubber parts is fixedly connected to the inner protective tube for threading.
[0011] As a further improvement of this utility model: the outer walls on both sides of the inner protective tube for threading are fixedly connected with fixing blocks at equal distances, and a tough spring is fixedly connected between the two sets of close fixing blocks.
[0012] As a further improvement of this utility model: the resilience spring is in the extended state by default, and the other end of the connecting bending component is fixedly connected with a threaded sleeve. The threaded sleeve and the threaded ring are threadedly connected to each other, and multiple sets of heat dissipation holes are opened on the surface of the connecting bending component.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model, by incorporating an outer protective tube, connecting bending components, and multiple sets of heat dissipation holes, effectively prevents the connecting cable from being damaged by bending, stretching, and torsion during the complex movements of industrial robots. Simultaneously, the heat dissipation holes effectively reduce temperature, preventing damage to the connecting cable due to overheating, thereby extending the cable's service life.
[0015] 2. Through the first and second rotating bearings, the outer protective tube can rotate flexibly as the robot moves, thereby avoiding the binding of the connecting wire and the protective tube due to the robot's movement, effectively improving the system's adaptability, and enabling the connecting wire and the protective tube to flexibly follow the robot's complex movements, reducing friction and damage during the movement process.
[0016] 3. This utility model, through the combination of a resilient rubber component and a resilient spring, effectively limits the bending angle of the connecting wire, reducing the mechanical stress borne by the connecting wire during frequent bending. The resilient spring can automatically restore its shape when the connecting wire is bent, reducing the risk of damage caused by excessive bending, while providing additional support to ensure the durability of the outer protective tube and the connecting wire.
[0017] 4. This utility model, through its threaded connection design, allows for quick and easy installation and disassembly of components such as the fixed base, threaded sleeve, and threaded ring, reducing maintenance time and costs. The threaded connection ensures the protective device is securely installed, guaranteeing the stability of the robot's connection cable during long-term use. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example 1
[0024] Reference Figure 1 , 2 This embodiment provides a robot connection line protection and reinforcement device, including a fixed base 1, a connecting bending member 2, and an outer protective tube 3. A first rotating bearing 4 is fixedly connected to the outer side of one end of the connecting bending member 2. A base threaded connector 5 is rotatably connected to the outer side of the first rotating bearing 4, and the base threaded connector 5 and the fixed base 1 are threadedly connected to each other. A second rotating bearing 8 is fixedly connected to the outer side of both ends of the outer protective tube 3. A threaded ring 7 is rotatably connected to the outer side of both sets of second rotating bearings 8. A threaded sleeve 6 is fixedly connected to the other end of the connecting bending member 2. The threaded sleeve 6 and the threaded ring 7 are threadedly connected to each other. Multiple sets of heat dissipation holes 13 are opened on the surface of the connecting bending member 2.
[0025] When the staff needs to use this utility model, the fixed base 1 is threaded onto both ends of the robot's output line. Then, the two sets of base threaded connectors 5 at one end of the two sets of connecting bending parts 2 are threaded onto the fixed base 1. The robot connection line is passed through the inner protective tube 10 inside the outer protective tube 4. The robot connection line is then passed through the connecting bending parts 2 for connection. The threaded rings 7 at both ends of the outer protective tube 3 are respectively inserted into the threaded sleeves 6 of the two sets of connecting bending parts 2 for connection. When the robot moves, the first rotating bearing 4 and the second rotating bearing 8 rotate with the robot's movement, so that the outer protective tube 3 can rotate flexibly with the robot's movement, thereby avoiding the binding of the connection line and the protective tube due to the robot's movement, reducing friction and damage during the movement. Multiple sets of heat dissipation holes 13 are opened on the surface of the connecting bending parts 2. The heat dissipation holes 13 can dissipate heat and cool down the connection line inside the inner protective tube, preventing the connection line temperature from being too high.
[0026] Example 2
[0027] Reference Figure 1 , 2 3. This embodiment is based on the previous embodiment, but differs from the previous embodiment in that the upper and lower ends of the inner sidewall of the outer protective tube 3 are fixedly connected with tough rubber parts 9, one end of each set of tough rubber parts 9 is fixedly connected to the inner protective tube 10 for threading, the outer sidewalls on both sides of the inner protective tube 10 for threading are fixedly connected with fixing blocks 11 at equal distances, and a tough spring 12 is fixedly connected between each set of two close fixing blocks 11. The tough spring 12 is in the spring-stretched state by default.
[0028] When the robot performs a task, it needs to continuously perform complex movements. The robot drives the connecting cable to bend, which in turn drives the inner protective tube 10 to bend. When the inner protective tube 10 drives the outer protective tube 3 to bend, it causes the tough spring 12 to deform. The tough spring 12 (which can recover its deformation after bending) reduces the bending angle of the inner protective tube 10 and the outer protective tube 3, thereby reducing the bending angle of the connecting cable. At the same time, the tough rubber component 9 provides a certain degree of toughness support and connects the outer protective tube 3 to the inner protective tube 10 on the inside. When an external object impacts the connecting cable, it provides cushioning. The combination of the inner protective tube 10 and the outer protective tube 3, along with the tough rubber component 9 and the tough spring 12, further enhances the protective effect. It not only protects the connecting cable but also avoids damage to the robot's connecting cable from external physical collisions, improving the safety and reliability of the robot's connecting cable.
