Sealing ring one-by-one conveying mechanism for assembling water pump

Abstract

The invention discloses a sealing ring one-by-one conveying mechanism for assembling a water pump. The sealing ring one-by-one conveying mechanism comprises a bottom plate and a top plate, a lifting frame is pressed against the bottom plate, an annular transmission belt is inserted into the lifting frame, a connecting block is fixed to the transmission belt in inserted and sleeved modes, the connecting block is fixed to the lifting frame, an upper belt wheel and a lower belt wheel are inserted into the upper end and the lower end of the transmission belt correspondingly, and the upper belt wheel and the lower belt wheel are fixed to an upper fulcrum shaft and a lower fulcrum shaft in inserted and sleeving modes respectively; and the outer end of the upper fulcrum shaft extends out of a side supporting plate and is fixedly provided with a transmission gear in inserted and sleeved modes, one side of the transmission gear meshes with an adjusting gear, an annular groove is formed in the side supporting plate, a stepped hole is formed in the position, on one side of a main shaft, of the adjusting gear and comprises a threaded hole and a connecting hole, a stud is connected into the threaded hole in a threaded mode, a handle is formed at one end of the stud, a limiting block is formed at the other end of the stud, and a plurality of limiting holes are formed in the annular groove. The sealing ring one-by-one conveying mechanism can be matched with a bearing jig of sealing rings, and the sealing rings can be conveniently taken out from the upper end of the bearing jig.

Description

technical field [0001] The invention relates to the technical field of water pumps, in particular to a one-by-one delivery mechanism for sealing rings used for assembling water pumps. Background technique [0002] Pump products are one of the important general-purpose mechanical products in various fields of the national economy, and centrifugal pumps are widely used for their high efficiency and large flow characteristics. At present, there are generally multiple seals in the centrifugal pump. The seal mainly adopts the seal ring. The seal ring includes a ring-shaped rubber gasket. There are several bolt holes formed on the rubber gasket. The inner ring of the rubber gasket is formed with a circular rubber ring sleeve. The rubber ring is inserted and sleeved on the load-bearing jig provided with the insertion rod by stacking. The load-bearing jig is composed of an X-shaped support plate at the bottom and insertion rods fixed at both ends of the support plate. The length of...

Problems solved by technology

However, when assembling the centrifugal pump, it is necessary to take out the sealing ring from the carrying fixture. The sealing ring on the top of the carrying fixture is convenient to take out from the carrying fixture, but when the sealing ring on the upper part of the carrying fixture is used up, it needs to be removed from the carrying fixture Take out the sealing ring from the bottom. It is more laborious to take the sealing ring from the bottom of the bearing fixture (because the insertion rod is long, the sealing ring needs to be separated from the insertion rod before it can be taken out)
