Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, and in particular to a liftable robotic arm. Background Technology

[0002] In actual on-site inspection and operation scenarios, staff need to grasp and position various workpieces to complete inspection or processing operations. However, the existing operation mode has obvious shortcomings—workpiece grasping is inconvenient and cannot be effectively fixed. On the one hand, without dedicated auxiliary equipment, staff may need to manually move and adjust workpieces. For workpieces that are heavy or irregularly shaped, the grasping process is time-consuming and laborious, with poor operational flexibility, which directly affects the smoothness of the operation process. On the other hand, the inability to stably fix the workpiece will lead to problems such as workpiece displacement and shaking in subsequent inspection or processing stages. Utility Model Content

[0003] The purpose of this utility model is to provide a liftable robotic arm that solves the problem that when there is a lack of dedicated auxiliary equipment, workers may need to manually move and adjust workpieces. For workpieces that are heavy or irregularly shaped, the grasping process is time-consuming and laborious, and the operation is not flexible, which directly affects the smoothness of the work process.

[0004] To achieve the above objectives, this utility model provides a liftable robotic arm, including a fixed base, a control assembly, and a gripping assembly. The control assembly includes a bearing base, a main rod, a motor base, a drive motor, and a lead screw. The bearing base is fixedly connected to the fixed base and located on top of the fixed base. The main rod is fixedly connected to the bearing base and located on top of the bearing base. The motor base is fixedly connected to the main rod and located on top of the main rod. The drive motor is fixedly connected to the motor base and located on top of the motor base. The lead screw is connected to the drive motor and passes through the motor base and the bearing base. The gripping assembly is connected to the main rod.

[0005] The control component further includes two protective covers, which are connected to the bearing base and the motor base respectively, and are located in the middle of the bearing base and the motor base respectively.

[0006] The gripping assembly includes a movable seat, a limiting rod, and an arm retraction seat. The movable seat is slidably connected to the main rod and is located between the main rod and the lead screw. There are multiple limiting rods, each of which is fixedly connected to the movable seat and passes through the main rod. The arm retraction seat is rotatably connected to the limiting rod and is located on the outside of the main rod.

[0007] The gripping assembly further includes a rotating seat and a locking arm. The rotating seat is fixedly connected to the arm retraction seat and is located outside the arm retraction seat. The locking arm is rotatably connected to the rotating seat and is located outside the rotating seat.

[0008] The gripping assembly further includes a rear arm, a forearm, a claw, and a locking bolt. The rear arm is rotatably connected to the arm retraction seat and is located outside the arm retraction seat. The forearm is rotatably connected to the rear arm and is located outside the rear arm. The claw is connected to the forearm and is located outside the forearm. The locking bolt is rotatably connected to the claw and passes through the claw.

[0009] This utility model discloses a height-adjustable robotic arm. The fixed base provides support for the device, the bearing base provides support and rotation for the lead screw, the main rod provides limiting for the moving seat and the arm retraction seat, and the motor base provides support for the drive motor. The drive motor controls the lead screw, and the lead screw controls the moving seat. In use, the drive motor rotates, causing the lead screw to rotate, which in turn causes the moving seat and the arm retraction seat to move up and down along the main rod. This facilitates control of the height position of the gripping component and solves the problem that when there is a lack of dedicated auxiliary equipment, workers may need to manually handle and adjust workpieces. For heavy or irregularly shaped workpieces, the gripping process is time-consuming and laborious, with poor operational flexibility, directly affecting the smoothness of the work process.
