Description

Technical Field

[0001] The present invention relates to the technical field of mechanical arms, and in particular to a mechanical arm for mechanical manufacturing. Background Art

[0002] With the rapid development of modern manufacturing, the demand for automated and intelligent equipment in the field of mechanical manufacturing is increasing. As a key equipment in the automated production line, the stability and flexibility of the performance of the robotic arm directly affect the production efficiency and product quality. Traditional robotic arm designs often have problems such as complex structure, insufficient flexibility, poor support stability, and limited ability to adapt to complex environments, which makes it difficult to meet the needs of modern manufacturing for efficient and precise operations.

[0003] In the prior art, the support structure of the robot arm usually adopts a fixed connection method, which limits the free movement and flexible operation of the robot arm in multi-dimensional space. In addition, the transmission system of the traditional robot arm mostly adopts a single gear transmission or chain transmission, which is not only inefficient but also easy to wear, resulting in a limited service life of the robot arm. At the same time, when dealing with complex working environments, existing robot arms often lack sufficient buffering and guiding mechanisms and are easily damaged by collisions or obstacles.

[0004] In order to solve the above problems, the industry has begun to explore new robot arm designs. Among them, a mechanical manufacturing robot arm with multiple degrees of freedom, high flexibility and strong stability has become a research hotspot. This robot arm uses complex rotation connections and transmission mechanisms to achieve free movement and precise operation in multi-dimensional space. At the same time, by introducing sensors and intelligent control systems, the robot arm can sense environmental changes in real time and make adaptive adjustments as needed.

[0005] However, despite the significant performance improvements of these new robotic arms, they still face some challenges in practical applications. For example, how to improve the support stability of the robotic arm while ensuring its flexibility; how to ensure the smooth operation of the robotic arm and reduce the failure rate in complex working environments; and how to reduce the production cost of the robotic arm to make it more adaptable to the needs of large-scale industrial production.

When the limiting rod 307 abuts against the inner wall of the fixed rod 301, the limiting rod 307 no longer moves. The sliding rod 301 drives the slider 304 to move toward the direction of the spring 1 303. The spring 1 303 is squeezed and contracted. When the limiting rod 307 reaches the position of the limiting hole 1, the limiting rod 307 enters the limiting hole 1, the sliding rod 301 stops sliding, and the left support assembly 30 provides axial support force for the rotating cross column 19.

[0062] When the motor 37 drives the rotating cross column 19 to rotate leftward, the right supporting assembly 13 provides an axial supporting force for the rotating cross column 19 .

[0063] The rotating cross column 19 can rotate on the transmission box, thereby driving the installation caliper 20 to rotate, realizing the effect of changing the angle of the installation caliper 20, so that the operating manipulator 21 can perform specific work on multiple positions. The transmission box 5 supports the limit bracket 22, and the limit bracket 22 supports the support bracket 23. At the same time, the support bracket 23 is used to support the rotating cross column 19, and the support bracket 23 can slide on the rotating cross column 19, thereby changing the position on the rotating cross column 19 to adjust the support center of gravity of the support bracket 23 on the rotating cross column 19. During adjustment, the electric telescopic rod 24 can work and retract, thereby driving the support bracket 23 to slide. The auxiliary hydraulic rod 25 can be extended and retracted when working, and can be extended and retracted according to the support card platform 23, so as to always support the support card platform 23. The limit slide bar 26 slides on the support card platform 23, and the support card platform 23 is supported by the limit slide bar 26. At the same time, the limit spring 27 set can be extended and retracted with the support card platform 23, and the limit spring 27 can be against the support card platform 23, thereby supporting one side of the bottom of the support card platform 23 to ensure the stability of the support card platform 23 after moving. The concave rotating rod 28 and the convex rotating rod 29 are mutually The concave rotating rod 28 can rotate along with the rotating crank arm 4, and the transmission box 5 can make the convex rotating rod 29 rotate on the concave rotating rod 28 after the rotation of the transmission box 5. When the convex rotating rod 29 rotates on the concave rotating rod 28, the auxiliary telescopic cylinder 30 starts to work, so that the telescopic length of the auxiliary telescopic cylinder 30 just maintains the distance generated by the angle formed by the convex rotating rod 29 and the concave rotating rod 28. The convex rotating rod 29 and the concave rotating rod 28 support the rotating bracket 3 and the transmission box 5, thereby further improving the working stability of the robot arm. The auxiliary cartridge 31 supports the extrusion telescopic rod 32, and the extrusion telescopic rod 32 can slide inside the auxiliary cartridge 31. Four auxiliary cartridges 31 and the extrusion telescopic rod 32 are provided to support the four corners of the support base 1 and increase the guide surface. A compression spring 33 is sleeved inside the auxiliary cartridge 31. When the support base 1 encounters an obstacle during movement, the guide wheel 35 will contact the obstacle. As the force after contact continues to increase, the guide wheel 35 and the U-shaped block 34 will continue to squeeze the extrusion telescopic rod 32. The compression spring 33 is further compressed, which can buffer the extrusion telescopic rod 32, the guide wheel 35 and the U-shaped block 34, thereby realizing the function of buffering and guiding when the support base 1 moves, and further improving the adaptability of the work.
