Abstract
The invention discloses an industrial-robot-based polishing system and technology for a bowl-shaped inner cambered surface of an annular titanium alloy casting. The industrial-robot-based polishing system for the bowl-shaped inner cambered surface of the annular titanium alloy casting is composed of an installation base, a robot, a force control sensor, an electric spindle installation seat, an electric spindle and an ER extension rod. The polishing technology comprises the steps of rough polishing, half-fine polishing and fine polishing, in the polishing process, force control is combined with hand-imitating polishing, and the bowl-shaped inner cambered surface of the annular titanium alloy casting can be polished to a high surface quality through the steps. By the adoption of the industrial-robot-based polishing system and technology for the bowl-shaped inner cambered surface of the annular titanium alloy casting, the polishing efficiency of the bowl-shaped inner cambered surface ofthe annular titanium alloy casting can be greatly improved, the surface roughness and the consistency of the polished surfaces of the polished workpieces can be guaranteed, and the polishing technology for the bowl-shaped inner cambered surface of the annular titanium alloy casting can be more complete.
Description
technical field [0001] The invention belongs to the field of mechanical processing, and relates to a polishing system and a process, in particular to a polishing system and process for a bowl-shaped inner arc surface of a titanium alloy annular casting based on an industrial robot. 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%. The polishing of the bowl-shaped inner arc surface of titanium alloy annular casting is one of the main processes in the processing of titanium alloy parts. Since titanium alloy is a difficult-to-machine material, the shape of the bowl-shaped inner arc surface is arc-shaped and the area is large. Large cutting force, hi...
