After the assembly is completed, the cylinder assembly drives the movable seat to move upward to separate the rotating head cover from the upper half, and the assembly efficiency is high, the assembly quality is good, and the degree of automation is high.

[0006] Preferably, the cylinder assembly includes a cylinder, a joint, a backing plate and a connecting seat, wherein the connecting seat is fixed on the top of the motor mounting seat, the cylinder is vertically mounted on the top plate in the longitudinal direction, and the telescopic shaft of the cylinder passes through the top plate and extends downward, the top of the joint is connected to the telescopic shaft of the cylinder, and the bottom of the joint is connected to the connecting seat.

It can realize the automatic alignment assembly of the upper and lower components of the pneumatic diaphragm valve, and has high assembly efficiency and good assembly quality. In actual work, it is only necessary to place the lower component of the pneumatic diaphragm valve on the clamp limit seat, and then place the upper component on the lower component, start the device, and the cylinder assembly drives the movable seat to move downward so that the rotating head cover contacts the upper component. At the same time, the rotating drive motor drives the rotating head cover to rotate through the reduction box, and the rotating head cover descends while rotating, so that the upper component can be quickly and stably screwed into the lower component, and the complete assembly of the pneumatic diaphragm valve is realized.
