Description

technical field [0001] The invention belongs to the technical field of aluminum alloy casting, and in particular relates to a low-pressure casting process for an aluminum alloy metal mold of a collaborative robot arm. Background technique [0002] In the past two years, collaborative robots have developed rapidly. Because the application of collaborative robots can reduce production costs, improve labor efficiency and the overall flexibility of the production system, they have been gradually applied to many precision industries such as automobiles, 3C, and IT electronics industries, especially for small parts. assembly applications. [0003] The collaborative robot arm cannot shake during high-speed motion, which is the key to achieving high-speed and smooth motion performance. At the same time, the collaborative robot arm is very slender but carries a large load, so even if it is installed in a small space for use, it can make the robot The possibility of the arm colliding...
