Valve body assembly tool

The invention discloses a valve body assembling tool which comprises a supporting mechanism, a plunger positioning floating mechanism and a locking mechanism, the supporting mechanism is used for supporting a valve body and is matched with the plunger positioning floating mechanism to jointly position the valve body, and the plunger positioning floating mechanism is used for positioning the position of the valve body on the supporting mechanism. And the locking mechanism is used for locking the plunger positioning floating mechanism. The valve body assembling tool has the beneficial effects that the valve body is supported through the supporting mechanism, the valve body is precisely positioned through the plunger positioning floating mechanism, and therefore automatic assembling of the valve rod is completed; therefore, after the valve rod is assembled, the supporting mechanism and the plunger positioning floating mechanism are used for precisely positioning the valve rod, namely the valve body can be precis
