4. The method of using a paint spraying apparatus for producing a gearbox body according to claim 1, comprising the steps of:
s1, arranging a gearbox housing between two shaft posts (31310), clamping and fixing the gearbox housing by using a rubber pier (322), then starting a paint spraying head (314) to spray paint to the gearbox housing, starting a driving motor (3134) in the process to drive a movable ring (3133) to rotate along an arc support (312), driving a gear ring (31312) on the movable ring (3133) to drive a fluted disc (31311) and the shaft posts (31310) on a movable seat (3136) to rotate, driving the clamped gearbox housing to horizontally rotate along a rocker (321), enabling the clamped gearbox housing to be fully exposed under the paint spraying head (314), enabling a rotating fluted disc (31311) to climb in along a gear ring (31312) on a fixed ring (3132), driving the movable seat (3136) to circumferentially revolve along the fixed ring (3132), the movable ring (3133) and a circular edge (3138), and enabling the paint spraying position to be three-dimensionally changed by continuously changing the angular position of the gearbox, so that paint spraying effect is good;
s2, after the paint liquid is sprayed onto the gearbox shell, the top and the bottom of the gearbox shell are alternated due to the vertical rotation of the gearbox shell, so that the paint liquid flowing downwards along the surface of the gearbox shell can be switched to an upper position to be uniform, the paint liquid is prevented from accumulating thick at the lower side of the gearbox shell, the upper side paint surface is thinned, meanwhile, the rocker (321) drives the clamped gearbox shell to horizontally rotate, the paint liquid can be uniformly flowed on the ring surface of the gearbox shell when the gearbox shell vertically rotates to be horizontal, and uneven side paint surfaces caused by the fact that the paint liquid is deflected to one side can be effectively avoided;
s3, after the paint spraying of the gearbox shell on the equipment is finished, a left conveyor belt (1) is started to convey the gearbox shell to be painted to a position of a differential ring painting assembly (3), the gearbox shell is conveyed between two relatively inclined rocking bars (321) and a rubber pier (322) by using a lifting machine or other measures, then the left rocking bar (321) is pushed to deflect into the equipment along a shaft column (31310), at the moment, a gap between the left rocking bars (321) and the rubber pier (322) is continuously closed, the gearbox shell is clamped and fixed, the rocking bars (321) and the rubber pier (322) in the original part deflect to the right, and the gearbox shell with the paint sprayed between the rubber piers (322) is loosened, so that a lever structure is realized by using the non-painted gearbox shell and the painted gearbox shell to be matched with the two groups of rocking bars (321), and the clamping and the loosening of the gearbox shell can be finished by only a small amount of force applied by an operator through the mutual balance of the gearbox shells on two sides;
s4, after the paint spraying of the gearbox shell fed into the left side is finished, the gearbox shell is fed into the right conveyor belt (2) to be operated reversely.
