A drain valve automatic capping device and valve cap assembly method

Abstract

The invention discloses an automatic drain valve deck screwing device which comprises a rack, a lifting mechanism arranged on the rack, an automatic deck feeding mechanism and a fixed valve body horizontal-moving mechanism. A deck screwing mechanism capable of moving up and down is arranged on the lifting mechanism and comprises a deck screwing motor and a valve deck sleeve connected with the deck screwing motor. The automatic deck feeding mechanism comprises a valve deck holding shaft and an ejecting cylinder used for ejecting out the valve deck holding shaft. A valve deck is fed into the valve deck sleeve through the ejecting cylinder, and driven by the deck screwing motor to rotate so as to be assembled with a valve body. The automatic drain valve deck screwing device further comprises a controller used for controlling operation of all cylinders and the motor. According to the automatic drain valve deck screwing device, since the valve deck and the valve body are automatically transported and installed, the assembling efficiency is greatly improved, the assembling precision and the product percent of pass are high, and the automatic drain valve deck screwing device can be widely used in the field of assembling of valve decks and valve bodies.

Description

technical field [0001] The invention relates to the field of special equipment for installing valve body screw caps, in particular to an automatic cap screwing device for drain valves. Background technique [0002] At present, in the same industry in China, the capping process in the assembly process of the washing machine drain valve is manually operated. It has been found that a mechanical device that can replace manual operation is found. The manual operation method is: the operator grasps the valve body with one hand, and the other Screw on the valve cap with one hand first, then tighten the cap tightly with a wrench. In the long-term production practice, three problems need to be solved: one is that the labor intensity of the workers is high, and they are prone to fatigue and irritability due to repeated actions for a long time; The phenomenon of wrong wire (the wire teeth are not aligned), resulting in water leakage; the third is that the degree of tightening of the v...
