Description

Technical Field

[0001] This utility model relates to the field of robot joint connection technology, and in particular to a carbon fiber robot joint connection device that can be quickly assembled and disassembled. Background Technology

[0002] With the development of robotics technology, carbon fiber composite materials are widely used in load-bearing components such as robot arms and support structures due to their advantages such as high specific strength, high specific modulus, lightweight, and corrosion resistance.

[0003] Existing carbon fiber robots typically use bolts or pneumatic quick-change tool trays to connect joints. However, bolts are cumbersome to install and remove, time-consuming, and labor-intensive, resulting in low replacement efficiency. While pneumatic quick-change tool trays can be used for rapid replacement, they require power to be applied for fixation and must be removed before power is cut off, making it difficult to ensure installation stability.

[0004] Therefore, a quick-assembly carbon fiber robot joint connection device has been developed that allows for rapid and convenient assembly and disassembly of the connecting arm while ensuring the stability of the connecting arm installation. Utility Model Content

[0005] To overcome the shortcomings of existing carbon fiber robots, where joints are typically connected using bolts or pneumatic quick-change tool trays, resulting in cumbersome assembly and disassembly and difficulty in ensuring installation stability, this invention provides a quick-assembly and disassembly carbon fiber robot joint connection device that enables rapid and convenient assembly and disassembly of the connecting arm while ensuring the stability of the connecting arm installation.

[0006] Technical solution: A quick-assembly and disassembly carbon fiber robot joint connection device includes a robotic arm, a connecting arm, a rotary joint, a fixing component, and a locking component. The robotic arm has a rotary joint on its right side, and the connecting arm is snapped onto the rotary joint. A fixing component for mutual connection and fixation is provided between the rotary joint and the connecting arm. The connecting arm has a locking component that can further lock the rotary joint.

[0007] Furthermore, it is particularly preferred that the fixing component includes a mounting sleeve, a connecting sleeve, a worm, a worm wheel, a rotating disk, and a limiting frame. The mounting sleeve is connected to the rotating joint, the connecting sleeve is rotatably connected to the connecting arm, the worm is rotatably connected to the upper side of the rotating joint, the rotating disk is rotatably connected to the mounting sleeve, the worm wheel is connected to the rotating disk and meshes with the worm, and the limiting frame is slidably connected between the upper and lower parts of the rotating disk and the mounting sleeve, and the limiting frame is engaged with the connecting sleeve.

[0008] Furthermore, it is particularly preferred that the worm gear is equipped with a knob.

[0009] Furthermore, it is particularly preferred that the locking assembly includes a rotating frame, a gear ring, a guide rod, a rack, a telescopic spring, and a limiting block. The rotating frame is connected to the middle of the connecting sleeve, and the rotating frame is rotatably connected to the connecting arm. The gear ring is rotatably connected to the rotating frame. Guide rods are connected to the left sides of both the front and rear parts of the connecting arm. A rack is slidably connected to each guide rod. The racks mesh with the gear rings. A telescopic spring is connected between each rack and the connected guide rod. A limiting block is connected to each rack, and the limiting block engages with the rotating joint.

[0010] In addition, it is particularly preferred that a limiting block is provided on the lower side of each guide rod.

[0011] Furthermore, it is particularly preferred that a torsion spring is included, with the gear ring and the rotating frame connected by a torsion spring.

[0012] The beneficial effects are as follows: 1. By rotating the connecting sleeve, the connecting sleeve is inserted into the mounting sleeve, connecting the connecting arm with the rotating joint. Then, the worm is rotated, and the worm meshes with the worm wheel, driving the rotating disk to rotate, causing the limiting frame to move inward and engage with the connecting sleeve, locking the connecting sleeve and the mounting sleeve, thus achieving the effect of quick and convenient installation of the connecting arm.

[0013] 2. As the connecting sleeve of this utility model rotates, it drives the rotating frame to rotate, causing the gear ring to rotate and mesh with the rack, pushing the rack to move outward along the guide rod. The telescopic spring is stretched, causing the limiting block to move outward and engage with the rotating joint, further fixing the connecting arm and the rotating joint, thus ensuring the stability of the connecting arm installation.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] A quick-assembly and disassembly carbon fiber robot joint connection device, such as Figures 1-6 As shown, it includes a robotic arm 1, a connecting arm 2, a rotary joint 3, a fixing component, and a locking component. The robotic arm 1 has a rotary joint 3 on its right side, and the connecting arm 2 is snapped onto the rotary joint 3. A fixing component is provided between the rotary joint 3 and the connecting arm 2, and a locking component is provided on the connecting arm 2.

[0023] like Figure 1 , Figure 2 and Figure 4 As shown, the fixing assembly includes a mounting sleeve 4, a connecting sleeve 5, a worm gear 6, a worm wheel 7, a rotating disk 8, and a limiting frame 9. The mounting sleeve 4 is connected to the rotating joint 3, the connecting sleeve 5 is rotatably connected to the connecting arm 2, the worm gear 6 is rotatably connected to the upper side of the rotating joint 3, and the worm gear 6 is provided with a knob for easy gripping and rotation. The rotating disk 8 is rotatably connected to the mounting sleeve 4, the worm wheel 7 is connected to the rotating disk 8, and the worm wheel 7 meshes with the worm gear 6. The upper and lower parts of the rotating disk 8 are slidably connected to the mounting sleeve 4 with the limiting frame 9, and the limiting frame 9 is engaged with the connecting sleeve 5.

[0024] like Figure 2 , Figure 5 and Figure 6As shown, the locking assembly includes a rotating frame 10, a gear ring 11, a torsion spring 12, a guide rod 13, a rack 14, a telescopic spring 15, and a limiting block 16. The rotating frame 10 is connected to the middle of the connecting sleeve 5. The rotating frame 10 is rotatably connected to the connecting arm 2. The gear ring 11 is rotatably connected to the rotating frame 10. The torsion spring 12 is connected between the gear ring 11 and the rotating frame 10. The left sides of both the front and rear parts of the connecting arm 2 are connected to the guide rods 13. The racks 14 are slidably connected to the guide rods 13. The lower side of each guide rod 13 is provided with a limiting block to limit the movement range of the racks 14. The racks 14 mesh with the gear ring 11. The telescopic spring 15 is connected between each rack 14 and the connected guide rod 13. The limiting block 16 is connected to each rack 14. The limiting block 16 is engaged with the rotating joint 3.

[0025] When using this utility model, firstly connect the connecting arm 2 with the robotic arm 1, insert the connecting arm 2 into the rotary joint 3, then rotate the connecting sleeve 5 so that the connecting sleeve 5 is snapped into the mounting sleeve 4, connecting the connecting arm 2 with the rotary joint 3. After that, rotate the worm 6, and the worm 6 meshes with the worm wheel 7, driving the rotating disk 8 to rotate, causing the limiting frame 9 to move inward and engage with the connecting sleeve 5, locking the connecting sleeve 5 and the mounting sleeve 4. The worm 6 and the worm wheel 7 self-lock, thus enabling the quick and convenient installation of the connecting arm 2. As the connecting sleeve 5 rotates, it drives the rotating frame 10 to rotate, causing the gear ring 11 to rotate and mesh with the rack 14, pushing the rack 14 to move outward along the guide rod 13. The telescopic spring 15 is stretched, causing the limiting block 16 to move outward and engage with the rotating joint 3, further fixing the connecting arm 2 and the rotating joint 3, thereby ensuring the installation stability of the connecting arm 2. Since the connecting sleeve 5 rotates a large range, when the connecting sleeve 5 continues to rotate, it drives the rotating frame 10 to continue rotating. At this time, the torsion spring 12 deforms, so that the gear ring 11 no longer rotates with it. When it is necessary to disassemble the connecting arm 2, rotate the worm gear 6 to disengage the limiting frame 9 from the connecting sleeve 5, and then rotate the connecting sleeve 5 to disengage the connecting sleeve 5 from the mounting sleeve 4. At this time, the rotating frame 10 rotates back to its original position, the torsion spring 12 returns to its original position, and the telescopic spring 15 rebounds, causing the limiting block 16 to disengage from the rotating joint 3. The connecting arm 2 can then be removed, thus enabling quick and convenient disassembly of the connecting arm 2 and improving replacement efficiency.
