Embodiment Construction

[0015] A manufacturing process of a robot joint, including the following manufacturing process steps: a. Material preparation: selecting raw and auxiliary materials for casting, melting in an electric furnace, and online monitoring of molten iron composition by a furnace thermal analyzer and a spectrometer;

[0016] b. Casting of robot joint castings: adopt the external hot-shooting core expansion process, and inlay and form cold iron on the isolated hot nodes of the castings, and set reinforcing ribs 1 on the suspended two sides of the robot joint castings, such as figure 2 As shown, a process boss 2 is added to the pressing point of machining. After the core is assembled, the pouring, cooling, and sand separation of the casting are realized by the fully automatic horizontal parting molding line, as shown in image 3 As shown, the reinforcing rib 1 of this process is removed with a cutting machine after the casting is tempered (at a temperature of 500°-550°) for 1.5-2 hours. ...

Abstract

The invention discloses a manufacturing method of robot joints with high-strength thin wall and high accuracy, which adopts a mode that expanding model and expanding core. Casting hot node embedding contoured chill and process strengthening rib, process lug boss and machine tooling are respectively provided with rough machining and finish machining pressing force, thereby increasing the casting accuracy of the joints, and improving the casting stress deformation and the machining pressing deformation. The quality of the joints reaches the international advanced level. The manufacturing process is stable and reliable, has high efficiency, lowers the cost, realizes the product localization, and replaces the import.

Description

Technical field [0001] The invention relates to a manufacturing process of a robot joint. Background technique [0002] With the development of science and technology, robots are widely used in medical, military, machinery, automobile and other industries. In the machinery and automobile industries, a robot not only needs precise positioning accuracy but also must have sufficient load-bearing capacity for specific objects, so the manufacture of important parts in the robot-joints must meet the requirements of high strength, thin wall and high precision . Due to various factors such as casting stress deformation and machining compression deformation of high-strength thin-walled and high-precision joints, there are still technical difficulties in domestic joint manufacturing, and they still have to be imported. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies, a manufacturing process for high-strength thin-walled and high-precision r...
