Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, specifically a lightweight robotic arm for industrial robots. Background Technology

[0002] Lightweight industrial robot arms are a new type of robot arm developed to address the problems of traditional industrial robot arms, such as large weight, high energy consumption, and limited mobility. Through optimized structural design and the use of new materials, they reduce the weight of the robot arm as much as possible while meeting the precision and load-bearing capacity requirements of industrial production tasks.

[0003] Existing robotic arm installation and disassembly technologies have many shortcomings. During installation, the process is cumbersome and complex, requiring the use of various tools to precisely tighten multiple bolts, which consumes a lot of time and effort and results in low installation efficiency. Disassembly is equally difficult, requiring not only the loosening of a large number of bolts but also special tools or specific methods, making it difficult to complete the disassembly and assembly quickly. Therefore, a lightweight robotic arm for industrial robots is proposed. Utility Model Content

[0033] The adjusting column 14 is installed inside the fixed ring 12 by threaded connection, and the pressure plate 20 is rotatably installed at the lower end of the adjusting column 14.

[0034] Please see Figure 2 and Figure 4The lower end of the pressure plate 20 is provided with six limiting protrusions 21 evenly distributed along the ring, and the upper end surface of the insertion plate 3 is provided with six limiting holes 7 evenly distributed along the ring. The limiting protrusions 21 and the limiting holes 7 are matched and the limiting protrusions 21 and the limiting holes 7 are combined to limit the position.

[0035] Please see Figure 2 , Figure 3 and Figure 4 An adjustment plate 15 is provided at the upper end of the adjustment column 14, and the adjustment plate 15 is fixedly connected to the adjustment column 14.

[0036] Please see Figure 2 , Figure 3 and Figure 4 The upper end of the adjusting plate 15 is equipped with four top shells 17 evenly distributed along the ring, and the top shells 17 are fixedly connected to the adjusting plate 15.

[0037] Please see Figure 2 , Figure 3 and Figure 4 The top shell 17 has a slide bar 18 installed inside, and the slide bar 18 is slidably connected to the top shell 17. A magnet block 19 is fixedly installed on the outside of the slide bar 18 near the top shell 17, and the magnet block 19 is magnetically connected to the top shell 17.

This method completes the quick installation of the robotic arm. When disassembling, rotate the adjusting plate 15 in the opposite direction to raise the pressure plate 20 and then slide the insertion plate 3 outward to move the robotic arm out.
