Description

Technical Field

[0001] The utility model relates to the technology of the field of industrial robots, in particular to an industrial robot wire harness adapter component. Background Art

[0002] Industrial robots are multi-joint manipulators or multi-degree-of-freedom machine devices widely used in the industrial field. They have a certain degree of automation and can rely on their own power and control capabilities to achieve various industrial processing and manufacturing functions. Industrial robots are widely used in various industrial fields such as electronics, logistics, and chemicals. Industrial robots are composed of three major parts and six subsystems. The three major parts are the mechanical part, the sensor part, and the control part. The six subsystems can be divided into the mechanical structure system, the drive system, the perception system, the robot-environment interaction system, the human-computer interaction system, and the control system. Therefore, a large number of wiring harnesses will be used inside the industrial robot, and the wiring harnesses between different components need to be connected through adapters.

[0003] In existing robots, after different wiring harnesses are connected, an adapter is formed, and the wiring harnesses on both sides of the adapter are fixed by external limiters. During the operation of the robot, it will rotate. At this time, the wiring harness will not only cause rotational friction with the external fixing parts, which is easy to damage the wiring harness, but also the adapter will become loose due to the rotation of the wiring harness, resulting in poor contact and affecting the stability of the wiring harness connection. Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

[0028] Please refer to Figures 1 to 4 as shown, which shows the specific structure of a preferred embodiment of the present utility model, including a body 10, a fixed wire clamp 20, a limiting member 30, and a fixing member 40.

[0029] The body 10 has an accommodating cavity 101 penetrating through both ends of the body, and installation grooves 102 are integrally recessed inward at both open ends of the accommodating cavity 101; the accommodating cavity 101 is used to accommodate the adapter between two wire harnesses. In other embodiments, resin glue can be poured into the accommodating cavity 101 to improve the sealing and waterproof performance at the wire harness adapter. In this embodiment, external threads 11 are provided on the outer side walls at both ends of the body 10. The body 10 is made of plastic material.

[0030] The fixing wire clamp 20 is provided in two sets. Each fixing wire clamp 20 is rotatably arranged in the corresponding installation groove 102, and the inner end of the fixing wire clamp 20 contacts the inner end side wall of the installation groove 102. A fixing hole 201 that cooperates with the external wire harness 50 penetrates through the fixing wire clamp 20, so that the external wire harness 50 can pass through the fixing hole 201 and extend into the accommodation cavity 101 to realize the connection with other wire harnesses. At the same time, the wire harness 50 is fixed through the fixing hole 201. With the rotation of the fixing wire clamp 20, sliding friction between the wire harness 50 and the fixing hole 201 is prevented. In this embodiment, the fixing hole 201 in one of the fixing wire clamps 20 is provided singly, and the fixing holes 201 in the other fixing wire clamp 20 are provided in multiple numbers. Similarly, the number of fixing holes 201 in each fixing wire clamp 20 can also be other numbers set according to actual situations.

[0031] The limiting member 30 is provided in two sets. Each limiting member 30 is arranged in the corresponding installation groove 102. The outer end of the limiting member 30 contacts and limits the outer end of the corresponding fixing wire clamp 20. The limiting member 30 is used to limit the outer end of the fixing wire clamp 20, so as to prevent the fixing wire clamp 20 from falling off the installation groove 102. In this embodiment, the limiting member 30 includes a main body 31 and elastic arms 32 integrally extending outward from the outer end of the main body 31. The elastic arms 32 are multiple and arranged at intervals in a ring shape. A limiting portion 33 that cooperates with the outer end of the fixing wire clamp 20 is integrally formed by bending the outer ends of the elastic arms 32. The arrangement of the elastic arms 32 is used to facilitate the assembly process of the limiting member 30 and the fixing wire clamp 20. The main body 31 is clamped between the inner side wall of the installation groove 102 and the outer side wall of the fixing wire clamp 20, and the limiting portion 33 wraps around the outer end of the fixing wire clamp 20 from the outside to the inside.

[0032] The fixing member 40 is provided in two sets. The two fixing members 40 are respectively fixedly installed at both ends of the main body 10 and limit the outer ends of the two limiting members 30. The fixing holes 201 in the fixing wire clamp 20 are exposed outside the outer ends of the corresponding fixing members 40. In this embodiment, internal threads 41 that cooperate with the external threads 11 are provided in the two fixing members 40. The two fixing members 40 are both fixedly installed at both ends of the main body 10 by screwing. In other embodiments, the fixing member 40 can also be fixedly installed at both ends of the main body 10 by buckling or other means. The two fixing members 40 are also made of plastic material, which not only improves the overall insulation performance, but also the screwing structure of the plastic material can improve the sealing performance and waterproof performance at the screwing connection. A plurality of anti-slip portions 42 arranged at equal angles are integrally protruded outward from the outer side wall of the fixing member 40. The anti-slip portions 42 are used to facilitate the installation and disassembly process between the fixing member 40 and the main body 10.

[0033] The design focus of the present utility model lies in that: there is a receiving cavity penetrating through both ends of the body inside the body, and mounting grooves are integrally recessed inward at the two open ends of the receiving cavity. The fixed wire clamp is rotatably arranged in the corresponding mounting groove, and a fixing hole for cooperating with an external wire harness penetrates through the fixed wire clamp. Through the fixation between the fixing hole and the external wire harness, when the robot drives the wire harness to rotate during operation, the fixed wire clamp can be driven to rotate simultaneously by the wire harness, thereby preventing mutual friction between the wire harness and the fixed wire clamp, avoiding wear of the wire harness. At the same time, the simultaneous rotation between the two fixed wire clamps can prevent the adapter located inside the receiving cavity from being subjected to torsional force, avoiding the situation of looseness and poor contact at the adapter, and ensuring the stability of the wire harness connection.

[0034] The above is only a preferred embodiment of the present utility model, and does not impose any limitation on the technical scope of the present utility model. Therefore, any minor modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
