Description

Technical Field

[0001] The present invention relates to the technical field of aluminum profiles, and particularly relates to a fixture for detecting a conductive busbar. Background Art

[0002] The power system is an energy source commonly used in people's lives. The conduction of electric power is usually carried out through conductive metals. Generally, high-voltage electric power is conducted using aluminum materials. Aluminum profiles can save costs and have sufficient production capacity to handle most high-voltage conduction scenarios. In the field of electric power conduction, busbars are used to converge multiple conductive lines. The busbars are generally formed by hot melting aluminum profiles and then are cut and polished to form finished products. Before being put into use, the busbars need to undergo various inspections to ensure their quality. The shape of the busbars is usually long. During the inspection process, the busbars are generally placed on a conveyor belt for inspection. Since the busbars have a certain weight, people generally suspend the busbars for transportation and inspection. Since the busbars are made of aluminum materials, when clamping the busbars, too strong a clamping force may cause deformation of the busbars, affecting the quality of the busbars.

[0018] Embodiment

[0019] Please refer to Figure 1 - Figure 2 , the present invention provides a fixture for detecting a conductive busbar, including a mounting arm 1 and a force arm assembly 2 hinged to the mounting arm 1. Two sets of force arm assemblies 2 can be retracted towards each other at intervals to clamp an object. An adsorption assembly 3 facing the other force arm assembly 2 is provided on each set of force arm assemblies 2. The mounting arm 1 is connected with a driving mechanism 4 that can drive the two sets of force arm assemblies 2 to change the interval. When the two sets of force arm assemblies 2 clamp an object, the adsorption assembly 3 can slide relative to the force arm assembly 2 and buffer the clamping force; in this solution, the two force arm assemblies 2 can retract towards each other or increase the interval between them to handle the clamping of an object. During the clamping process, the force arm assemblies 2 will approach each other, and the adsorption assembly 3 on the force arm assemblies 2 will first contact the object and adsorb the object during the clamping process, and the clamping force of the force arms will not damage the object. The adsorption assembly 3 can improve the adsorption capacity of the whole device, and still be able to achieve the clamping effect on the object in cooperation with the clamping capacity; further, during the process of releasing the force arm assembly 2, the adsorption assembly 3 can reduce the adsorption capacity during the process of releasing the force arm assembly 2, thus facilitating the user to take the object.

[0020] In a specific embodiment, referring to Figure 1 、 Figure 2, the lever arm assembly 2 includes a connecting member 21 and a clamping member 22. One end of the clamping member 22 is hinged to the mounting arm 1 through at least two connecting members 21, and the distances between the hinge points of each connecting member 21 with the mounting arm 1 and the clamping member 22 are equal. In this solution, each clamping member 22 is connected to two connecting members 21, which can form a quadrilateral connection. The minimum number of connecting members 21 is two, and the types of connecting members 21 of the two sets of lever arm assemblies 2 are the same, which can ensure the consistency of the two clamping members 22 when clamping an object.

[0021] In a specific embodiment, refer to Figure 1 , Figure 2 , the adsorption assembly 3 includes a hollow branch pipe 31 and a suction cup 32. One end of the branch pipe 31 facing the other set of lever arms is connected to a disc body 33. The center of the suction cup 32 is connected to a hose 35. The hose 35 passes from one end of the disc body 33 connected to the branch pipe 31 to the other end of the branch pipe 31. A bolt 34 is threadedly connected to the side of the branch pipe 31 and penetrates into the branch pipe 31. One end of the bolt 34 located inside the branch pipe 31 is connected to a plug body 341 and squeezes the hose 35 to seal one end of the hose 35. In this solution, the entire adsorption assembly 3 has a buffering effect. When the two clamping members 22 clamp an object, the adsorption assembly 3 will first contact the object. At this time, the suction cup 32 can abut against the object. During the continuous retraction process, the suction cup 32 will also abut against the disc body 33, squeeze the air inside the suction cup 32, and adsorb the object.

[0022] In a specific embodiment, refer to Figure 1 , Figure 2 , a hollow groove 221 is provided in the middle of the clamping member 22, and connecting ears 222 are provided on both sides of the clamping member 22. The branch pipe 31 passes through the hollow groove 221. A guide rod 331 penetrating the connecting ear 222 is connected to one side of the disc body 33 facing the branch pipe 31. An elastic member 36 is sleeved on the guide rod 331, and both ends of the elastic member 36 abut against the connecting ear 222 and the disc body 33 respectively. In this solution, for the above solution, the guide rod 331 provides a guiding effect for the branch pipe 31, and the branch pipe 31 can slide laterally relative to the clamping member 22. When clamping an object, the branch pipe 31 can slide in a direction away from the suction cup 32 and squeeze the elastic member 36. The elastic member 36 is a spring, and the elastic member 36 can provide a buffering effect for the suction cup 32 to squeeze the object.

[0023] In a specific embodiment, refer to Figure 1 , Figure 2, slots 311 communicating with the inside of the branch pipe 31 are provided on both the upper and lower surfaces of the branch pipe 31. A roller 37 is rotatably installed in the empty slot 221. The two rollers 37 are embedded in the slots 311 to squeeze and block the hose 35. The hose 35 is provided with side holes 351, and the side holes 351 are located in the area of the slots 311. In this solution, between the clamped objects, the side holes 351 are located between the roller 37 and the suction cup 32 of a single force arm assembly 2. During the process of clamping an object, since the branch pipe 31 will slide relative to the clamping member 22, its roller 37 will continuously approach the side holes 351 until the side holes 351 are located on the side of the roller 37 away from the suction cup 32. At this time, the suction cup 32 only has an opening at the center of the end, which can provide a stable suction force for the suction cup 32. When it is necessary to release the object, the roller 37 will continuously move to the side of the side holes 351 away from the suction cup 32. At this time, the suction cup 32 will release the injected air through the side holes 351 and does not have a suction effect, thereby achieving the effect of releasing the object.

[0024] In a specific embodiment, referring to Figure 1 , Figure 2 , the driving mechanism 4 includes a solenoid valve 41 and a rack 42. The mounting arm 1 is provided with a cavity 11 with an opening facing downwards. The rack 42 is slidably installed in the cavity 11. One end of the connecting member 21 close to the rack 42, which is hinged to the mounting arm 1, is provided with a tooth key 211 arranged in an arc. The tooth key 211 meshes with the rack 42. The solenoid valve 41 is installed above the cavity 11 and penetrates into the cavity 11 to adsorb the rack 42. A spring 12 is installed in the cavity 11, and both ends of the spring 12 abut against the rack 42 and the solenoid valve 41 respectively. In this solution, the force arm assembly 2 is controlled by the solenoid valve 41. When the solenoid valve 41 operates, the solenoid valve 41 can attract the rack 42 to move upwards. The movement of the rack 42 will drive the tooth key 211 at the end of the connecting member 21 to rotate, and then the connecting member 21 will swing, enabling the clamping members 22 to approach each other. Conversely, they will move away from each other.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
