S10: watch cover dress upset arm and press from both sides and get assembly arm: at the turntable assembly position 5 (6 positions in total, the storage position at the position 4 and the empty position at the position 6), after the meter cover, the gasket and the lens are detected to be assembled, the overturning mechanical arm clamps the meter cover and overturns, and the clamping assembly mechanical arm clamps the meter cover on the overturning arm and assembles the meter cover on the speed chain station No. 3.

S11: a pre-tightening mechanism: and conveying the copper shell part to the No. 4 station by the speed multiplying chain No. 3 station tooling plate, detecting downwards by a pre-tightening machine, executing pre-tightening action with set pre-tightening action, and screwing the watch cover onto the copper shell (not screwing).

S12: the tightening mechanism: a speed chain 4 station tooling plate transports the water meter to a 5 station, a tightening machine meter taking mechanical arm clamps the water meter and puts the water meter to a tightening machine positioning tool, the tightening machine downwards probes and tightens a meter cover, the tightening force reaches a set torque, a shifting cylinder pushes the water meter to a manual meter taking position, and a person takes the water meter away.

The above description is only a preferred embodiment of the present disclosure and is not intended to limit the present disclosure, and various modifications and changes may be made to the present disclosure by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present disclosure should be included in the protection scope of the present disclosure.
