Multi-freedom-degree controllable spray painting robot

The invention discloses a multi-freedom-degree controllable spray painting robot which comprises a waist lifting mechanism, a shoulder lifting mechanism, an elbow swing mechanism, a spray gun swing mechanism, a machine frame and a swing platform. The machine frame is arranged on the swing platform. A main motor can be arranged on the machine frame and control swinging of a first driving rod, a second driving rod, a third driving rod and a spray gun base, and accordingly the waist lifting mechanism, the shoulder lifting mechanism, the elbow swing mechanism and the spray gun swing mechanism are driven to swing at a working space. The rods can be made into light rods, mechanism dynamics performance is good, performance is stable, reliability is good, the high-speed high-accuracy spray painting requirements can be met, working space is large, flexibility is high, control is convenient, machining is easy, working is reliable, and the multi-freedom-degree controllable spray painting robot is suitable for small-scale common spray painting work and large-scale or heavy structure spray painting work.
