Abstract
Description
Technical Field
[0001] This utility model relates to the field of robotic arm technology, specifically to a robotic arm robot equipped with a length adjustment component. Background Technology
[0002] In today's highly automated and intelligent industrial production environment, robotic arms play a crucial role as important automated equipment. They are capable of performing various complex, precise, and repetitive tasks, such as assembly, welding, handling, and painting, which greatly improves production efficiency and quality while reducing the intensity of manual labor and lowering production costs.
[0003] The design principles of robotic arms are mainly based on the combination of bionics and mechanical engineering. By simulating the structure and movement of the human arm, they achieve multi-degree-of-freedom and flexible operation. Traditional robotic arms typically consist of a base, upper arm, forearm, wrist, and end effector. Each part is connected by joints, which are equipped with drive devices (such as motors, hydraulic cylinders, or pneumatic cylinders) and transmission mechanisms (such as gears, chains, or belts) to achieve rotation, extension, and other movements.
[0004] In traditional robotic arm designs, the length is usually fixed, making it difficult to adjust on-site once manufactured. While this design simplifies the mechanical structure and control system, it introduces numerous inconveniences in practical applications. For example, in confined spaces, an excessively long robotic arm may be unable to reach or operate flexibly; conversely, in situations requiring long-distance transport, the arm's length may be insufficient to reach the target location.
[0005] Therefore, to address the above problems, the applicant needs to design a robotic arm robot equipped with a length adjustment component to solve the problem. Utility Model Content
[0006] The purpose of this invention is to provide a robotic arm equipped with a length adjustment component to solve the problems mentioned in the background section.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a robotic arm robot equipped with a length adjustment component, including a base,
[0008] It also includes: a base disposed above the base, and a first rotating sleeve fixedly disposed on the base, a fixed arm rotatably disposed inside the first rotating sleeve, and a second rotating sleeve rotatably disposed at the end of the fixed arm away from the first rotating sleeve, a connecting member rotatably disposed inside the second rotating sleeve, and a telescopic rod fixedly disposed on one side of the connecting member, a rotating block rotatably disposed at the end of the telescopic rod away from the connecting member, and a connecting arm disposed on the rotating block, and a robot arm disposed on the connecting arm, and the robot arm is used to clamp the workpiece;
[0009] An adjustment mechanism is located below the telescopic rod and is used to control the length of the telescopic rod. The adjustment mechanism includes a hydraulic cylinder, one end of which is fixedly fitted with a fixing sleeve, which is fixedly connected to the output end of the telescopic rod.
[0010] Furthermore, the hydraulic cylinder is fixedly connected to an oil pipe for oil flow, and the end of the oil pipe away from the hydraulic cylinder is connected to a storage tank, which is fixedly connected to the base.
[0011] Through the above structural design, the storage tank can easily supply oil to the hydraulic cylinder through oil pipelines, which facilitates the circulation of oil within the hydraulic cylinder, thereby driving the output rod of the hydraulic cylinder to reciprocate.
[0012] Furthermore, an oil inlet pipe is fixedly installed on the storage tank, and a movable cover is rotatably installed on the oil inlet pipe. A sealing plug is installed inside the movable cover, and the sealing plug is used to block the oil inlet pipe.
[0013] The above structural design allows for easy supply of oil to the storage tank via the oil inlet pipe, and the movable cover and sealing plug facilitate opening or closing of the oil inlet pipe, ensuring high safety.
[0014] Furthermore, a locking component is fixedly installed on the storage box, and a locking block is fixedly installed on the movable cover. The locking block and the locking component cooperate to close the movable cover and the oil inlet pipe and lock them together.
[0015] The above structural design allows for easy locking of the oil inlet pipe and movable cover by cooperating with the locking component and locking block, thereby improving the sealing performance between the oil inlet pipe and movable cover.
[0016] Furthermore, the locking component includes a connecting block that is fixedly connected to the storage box, and a fixing shell is fixedly provided on the connecting block. A sliding rod is provided on the inner side of the fixing shell, and a movable handle is provided on the sliding rod. A locking sleeve is provided on the movable handle, and the locking sleeve is adapted to the locking block.
[0017] Through the above structural design, the movable handle can be rotated by external force to easily loosen the locking sleeve, thereby facilitating the separation of the locking sleeve from the locking block and making it easier to open the movable cover. The operation is convenient and labor-saving.
[0018] Furthermore, a support rod is provided inside the fixed shell, and a limiting component is provided on the support rod. The limiting component cooperates with the movable handle to lock the locking sleeve.
[0019] Through the above structural design, the limiting component makes it easy for the locking sleeve to securely lock the locking block.
[0020] Furthermore, a fixed seat is fixedly installed on the hydraulic cylinder, and the fixed seat is fixedly connected to the connecting piece.
[0021] The above structural design utilizes a fixed base to easily support the hydraulic cylinder, thereby improving the stability and robustness of the hydraulic cylinder during use.
[0022] Compared with the prior art, the beneficial effects of this utility model are: the robotic arm robot equipped with a length adjustment component is easy to adjust its length using a hydraulic cylinder, and has a wide range of applications. The specific details are as follows:
[0023] When in use, this robotic arm equipped with a length adjustment component grips a workpiece and adjusts its working position using a first rotating sleeve, a fixed arm, a second rotating sleeve, a connector, a rotating block, and a connecting arm. When the target working position of the robotic arm needs to be adjusted, the hydraulic cylinder is activated. The hydraulic cylinder pushes the fixed sleeve to move, which in turn moves the telescopic rod. The movement of the telescopic rod facilitates the adjustment of the total working length of the rotating block and the connecting arm, thereby adjusting the working length of the robotic arm and improving its applicability.
[0024] When the robotic arm equipped with a length adjustment component needs to add oil to the hydraulic cylinder, external force is used to pull the movable handle. The movement of the movable handle will release the connection between the locking sleeve and the locking block, making it easier to open the movable cover. The opening of the movable cover will facilitate the supply of oil to the storage tank. The oil will enter the hydraulic cylinder through the oil pipeline, which will facilitate the stable use of the hydraulic cylinder and improve work efficiency. Attached Figure Description

A connecting member 14 is rotatably disposed inside the second rotating sleeve 13, and a telescopic rod 15 is fixedly disposed on one side of the connecting member 14. The end of the telescopic rod 15 away from the connecting member 14 rotates... A rotating block 16 is provided, and a connecting arm 17 is provided on the rotating block 16. A robot arm 18 is provided on the connecting arm 17 and is used to clamp the workpiece. An adjustment mechanism 2 is provided below the telescopic rod 15 and is used to control the length of the telescopic rod 15. The adjustment mechanism 2 includes a hydraulic cylinder 20.

A fixing seat 29 is fixedly provided on the hydraulic cylinder 20 and is fixedly connected to the connecting piece 14.
[0033] With the above structural design, during use, the robot arm 18 clamps the workpiece and adjusts the working position of the robot arm 18 using the first rotating sleeve 11, fixed arm 12, second rotating sleeve 13, connector 14, rotating block 16 and connecting arm 17. When it is necessary to adjust the target working position of the robot arm 18, the hydraulic cylinder 20 is activated. The hydraulic cylinder 20 will push the fixed sleeve 21 to move, and the fixed sleeve 21 will drive the telescopic rod 15 to move. The movement of the telescopic rod 15 will facilitate the adjustment of the total working length of the rotating block 16 and the connecting arm 17, thereby adjusting the working length of the robot arm 18 and improving the applicability of the robot arm.
[0034] A hydraulic cylinder 20 is fixedly connected to an oil pipe 22 for oil flow. The end of the oil pipe 22 furthest from the hydraulic cylinder 20 is connected to a storage tank 23, which is fixedly connected to the base 1. An oil inlet pipe 24 is fixedly installed on the storage tank 23, and a movable cover 25 is rotatably mounted on the oil inlet pipe 24. A sealing plug 27 is installed inside the movable cover 25 to block the oil inlet pipe 24. A locking component 28 is fixedly installed on the storage tank 23, and a locking block 26 is fixedly installed on the movable cover 25.

Opening the movable cover 25 will facilitate the supply of oil to the storage tank 23. The oil will enter the hydraulic cylinder 20 through the oil pipe 22, facilitating the stable operation of the hydraulic cylinder 20. During use, the robotic arm 18 clamps the workpiece and adjusts the working position of the robotic arm 18 using the first rotating sleeve 11, the fixed arm 12, the second rotating sleeve 13, the connecting piece 14, the rotating block 16, and the connecting arm 17.
