Description

Technical Field

[0001] This utility model relates to the field of arc-shaped robotic arms, and in particular to an arc-shaped telescopic robotic arm. Background Technology

[0002] Airships, as lighter-than-air aircraft, are widely used in air transport, reconnaissance, scientific research, and entertainment due to their high efficiency, energy saving, and ability to carry large quantities of cargo. During the use and maintenance of airships, the outer membrane (i.e., the airship's shell material) needs frequent folding, unfolding, or maintenance. To improve efficiency and protect the integrity of the airship membrane, the development of specialized folding equipment is particularly important, and telescopic robotic arms are widely used in this process.

[0003] However, existing robotic arms mostly employ linear motion or simple multi-joint motion methods. When faced with high-precision, curved paths, the mismatch between the folding paths often leads to low work efficiency. Furthermore, the disassembly and replacement of the robotic gripper typically involves bolt fixation, making the disassembly and replacement process complex and further reducing efficiency. To address these issues, those skilled in the art have proposed an arc-shaped telescopic robotic arm to solve these problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an arc-shaped telescopic robotic arm, which aims to improve the problem that existing robotic arms mostly use linear motion or simple multi-joint motion, and often have low work efficiency due to mismatched folding paths when facing high-precision, arc-shaped paths.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an arc-shaped telescopic robotic arm, comprising a mounting block, a telescopic mechanism being provided on the top of the mounting block, a disassembly mechanism being provided at the end of the telescopic mechanism away from the mounting block, and a clamping mechanism being provided outside the disassembly mechanism;

[0006] The telescopic mechanism includes an arc-shaped block one, one end of which is fixedly connected to the outside of the mounting block. A first motor is installed inside the arc-shaped block one, and a drive gear is fixedly connected to the output end of the first motor. The end of the drive gear away from the first motor is rotatably connected to the inner wall of the arc-shaped block one. An arc-shaped block two is rotatably connected to the inner wall of the arc-shaped block one, and a rack is installed on the outside of the arc-shaped block two.

[0007] Furthermore, the disassembly mechanism includes a fixing block, which is installed at one end of the arc-shaped block two. A movable slider is slidably connected inside the fixing block. A pull rod is fixedly connected to one end of the movable slider. Two locking blocks are slidably connected inside the fixing block. A connecting rope is provided inside the fixing block, with one end fixedly connected to the outside of the movable slider. The two ends of the connecting rope away from the movable slider are fixedly connected to the outside of the two locking blocks. Two springs are installed inside the fixing block.

[0008] Furthermore, the clamping mechanism includes a mounting base, the outside of which is slidably connected to the inside of a fixed block. A second motor is mounted on the outside of the mounting base, and a main gear is fixedly connected to the output end of the second motor. A secondary gear is rotatably connected to the outside of the mounting base, and a half gear is rotatably connected to the outside of the mounting base. One end of the secondary gear is rotatably connected to a clamping block one, and one end of the half gear is rotatably connected to a clamping block two. The main gear is externally meshed with the outside of the secondary gear.

[0009] Furthermore, the rack is externally meshed with the drive gear, and the auxiliary gear is externally meshed with the half gear.

[0010] Furthermore, one end of the spring is fixedly connected to the outside of the locking block, and the end of the spring away from the locking block is fixedly connected to the inner wall of the fixing block.

[0011] Furthermore, the fixing block is internally fixedly connected to two positioning rods, and the positioning rods have grooves on their outer surfaces, with the connecting rope disposed in the grooves of the positioning rods.

[0012] Furthermore, a connecting block is rotatably connected to the outside of the mounting base, and the end of the connecting block away from the mounting base is rotatably connected to the outside of the clamping block two.

[0013] Furthermore, the bottom of the mounting base has two slots, and one end of the locking block is slidably connected to the inner wall of the slot.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the first motor inside the arc-shaped block one drives the drive gear to rotate, thereby driving the arc-shaped block two to extend and retract. This improves the flexibility and stability of the robotic arm, solves the problems of insufficient clamping force and poor adaptability in the prior art, and has higher adaptability and operating precision.

[0016] 2. In this utility model, by pulling the pull rod to move the sliding block, the connecting rope is subjected to tension. Combined with the limiting effect of the positioning rod, the locking block is moved out of the slot. This improves the ease and efficiency of operation, solves the problems of complicated replacement and difficult disassembly in the prior art, and enhances the adaptability and work efficiency of the robotic arm.

The drive gear 205 is used to transmit the power of the first motor 202. The end of the drive gear 205 away from the first motor 202 is rotatably connected to the inner wall of the arc-shaped block 201. An arc-shaped block 203 is rotatably connected to the inner wall of the arc-shaped block 201. The arc-shaped block 203 is used for extension. A rack 204 is installed on the outside of the arc-shaped block 203. The rack 204 is used to mesh with the drive gear 205 to realize the telescopic action of the robotic arm. The rack 204 is externally meshed and connected to the outside of the drive gear 205. The secondary gear 404 is externally meshed and connected to the outside of the half gear 409.

[0026] Reference Figure 1 and Figure 4The disassembly mechanism 3 includes a fixed block 301, which is installed at one end of the arc-shaped block 203. A movable slider 302 is slidably connected inside the fixed block 301, driving the connecting rope 304 to move. A pull rod 303 is fixedly connected to one end of the movable slider 302, transmitting external force and driving the movable slider 302 to move. Two locking blocks 306 are slidably connected inside the fixed block 301, used to hold or release the object during disassembly. A connecting rope 304 is installed inside the fixed block 301, with one end fixedly connected to the outside of the movable slider 302. The two ends of the connecting rope 304 away from the movable slider 302 are fixedly connected to the outside of the two locking blocks 306. The connecting rope 304 is used to coordinate the two... The locking block 306 moves. Two springs 307 are installed inside the fixing block 301.

This gear, through meshing with the rack 204, drives the arc-shaped block 203 to move along the arc trajectory, thereby adjusting the length of the robotic arm. This allows the robotic arm to adapt to different task requirements. The second motor 402 drives the main gear 403, which, in conjunction with the meshing of the auxiliary gear 404 and the half gear 409, transmits power to the clamping blocks 405 and 406. Under the limiting action of the connecting block 408 and the connecting block 407, the clamping of the target object is completed.

[0028] When the clamping mechanism 4 needs to be replaced, the pull rod 303 is pulled to move the sliding block 302, thereby causing the connecting rope 304 to be under tension. With the limiting effect of the positioning rod 305, the locking block 306 is pulled out of the slot 308. The spring 307 is used to generate a rebound force when the pull rod 303 is released, thereby facilitating the installation and disassembly steps.
