Abstract
The invention discloses a process for removing the oxidation layer of a bowl-shaped titanium alloy casting based on a robot. The equipment used in the process includes a base, a robot, a force control sensor, an electric spindle mounting seat, an electric spindle, and a tool. This process uses a force control sensor to control the contact force between the tool and the surface of the workpiece, so that the robot will grind a trace on the surface of the workpiece when it moves according to the specified path. After that, each time it completes the path, it will offset a certain distance in the same direction to obtain smoothness. s surface. Finally, every time a surface of a certain width is polished, the workpiece is rotated for a small arc, so that the oxide layer on the surface of the entire bowl-shaped workpiece can be removed and a better surface roughness can be obtained. The invention can realize the technical problem of automatic grinding of the oxide layer on the surface of the bowl-shaped titanium alloy casting, greatly improves the grinding efficiency of the bowl-shaped titanium alloy casting, and can ensure the roughness of the workpiece surface after grinding and the consistency of the processed surface, making the bowl-shaped titanium alloy casting The titanium alloy casting process is more perfect.
Description
technical field [0001] The invention belongs to the field of machine processing, and relates to a part surface processing technology, in particular to a robot-based process for deoxidizing a bowl-shaped titanium alloy casting. Background technique [0002] Titanium alloy has high specific strength and good heat and corrosion resistance. It is a light-weight high-temperature structural material and has been widely used in military fields such as aviation, navigation, chemical industry, and weaponry. Net-shaped structural parts reduce production costs, and the application ratio accounts for more than 90%. A certain titanium alloy casting part, similar to a bowl, is one of the main processes in the processing of titanium alloy parts. Since titanium alloy is a difficult-to-machine material, there are small operating space, irregular processing surface and large processing area in the processing process. These problems have seriously restricted the grinding efficiency and surfac...
