Aluminum alloy metal mold low-pressure casting technological method for collaborative robot arm

Abstract

The invention discloses an aluminum alloy metal mold low-pressure casting technological method for a collaborative robot arm. The method comprises the following steps of 1, three-dimensional modelingof the arm; 2, design of a casting technological scheme; 3, mold flow analysis; 4, design of a metal mold low-pressure casting mold and an arm inner chamber hot box mold; 5, manufacturing of the metalmold low-pressure casting mold and the arm inner chamber hot box mold; 6, manufacturing of an arm inner chamber film-coated sand core, and surface coating; 7, sand blasting and paint spraying of themetal mold low-pressure casting mold; 8, smelting and feeding of a metal mold low-pressure casting alloy; 9, mounting of the sand core through metal mold low-pressure casting; 10, pouring of metal mold low-pressure casting castings; and 11, heat treatment of the metal mold low-pressure casting castings. The collaborative robot arm manufactured through the method has the beneficial effects of beingsmall in weight, high in rigidity, high in inner chamber precision and attractive and delicate in outer surface.

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...

Problems solved by technology

[0004] Traditional industrial robot arms are generally produced by sand mold or gravity casting, but the shortcomings of the sand mold casting process and the gravity casting process itself have always restricted the mass production of this advanced high-precision collaborative robot arm.
