Detailed Description
A spray gun of a robot suitable for casting single crystal as shown in figure 1 is installed by the following steps:
step 1) coating uniform lubricating grease on a pressing group 7, screwing the lubricating grease into a cavity of a piston 5 of a gun body 8, using a torque wrench, and adjusting the torque to be 6 N.m-7 N.m;
step 2), sleeving the sealing ring 3 into a groove on the periphery of the piston 5;
step 3) screwing the head of the gun core 6 into the concave surface of the piston 5, so that the head of the gun core 6 extends out of the convex surface of the piston 5, partial threads are left to be unscrewed, and the length of the unscrewed thread section is 0.1 +/-0.02 mm;
step 4), connecting the locking nut 4 to the head of a gun core 6 extending out of the convex surface of the piston 5 through threads to obtain a piston 5 assembly;
step 5), inserting the piston 5 assembly from the center of the pressing group 7, and enabling the gun core 6 to extend out of the other end of the gun body 8;
step 6) screwing the gun nozzle 9 into the front end of the gun body 8, simultaneously propping against the piston 5 by fingers to prevent the position displacement of the piston 5, when the fingers feel the pressure transmitted from the gun nozzle 9 through the gun core 6, loosening the fingers, and reversely rotating the gun nozzle 91-1.5 circles;
step 7), taking out the piston 5 assembly, and rotating the locking nut 4 to lock the gun core 6 and the piston 5;
step 8) uniformly coating lubricating grease on the periphery of the sealing ring 3 and then filling the sealing ring into the gun body 8 again
