Abstract
The invention discloses a process for removing the oxidation layer of a bowl-shaped titanium alloy casting based on a robot. Equipment adopted in the process comprises a base, the robot, a force control sensor, an electric spindle mounting seat, an electric spindle and a tool. The process is characterized in that the force control sensor is used for controlling the contact force between the tool and the surface of a workpiece so that the robot can grind a trace on the surface of the workpiece when the robot moves according to a specified path, the robot deviates towards the same direction by acertain distance every time when the robot finishes walking along the path, and then a smooth surface is obtained; and finally, the workpiece is rotated by a small section of radian every time when the surface is ground by a certain width so that the oxidation layer on the surface of the whole bowl-shaped workpiece can be removed, and then the good surface roughness can be obtained. According tothe process for removing the oxidation layer of the bowl-shaped titanium alloy casting based on the robot, the automatic grinding technological problem of the oxidation layer on the surface of the bowl-shaped titanium alloy casting can be solved, so that the grinding efficiency of the bowl-shaped titanium alloy casting is greatly improved; and the roughness of the surface of the ground workpiece and the consistency of the machined surface can be ensured, so that the process of the bowl-shaped titanium alloy casting is more complete.
Description
technical field [0001] The invention belongs to the field of machine processing, relates to a part surface processing technology, and in particular relates to a robot-based bowl-shaped titanium alloy casting process for removing oxide layers. Background technique [0002] Titanium alloy has high specific strength and good heat and corrosion resistance. It is a lightweight high-temperature structural material. It has been widely used in military fields such as aviation, navigation, chemical industry, and weaponry. Net 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 during processing. These problems seriously restrict the grinding efficiency and surface quali...
