Material, and often occurring since bearing shell and base aperture are bad to neutrality in the cold charge presses watt process, and by bearing shell
The phenomenon of pressure break damage.
The content of the invention
In view of this, the utility model is intended to propose submersible electric pump Internal hole positioning type last item bricklayer for deeper bearing shell hole
Tool, with solve to during deeper pedestal bearing shell pore pressure dress bearing shell because of bearing shell pressure break phenomenon that Disalignment produces.
To reach above-mentioned purpose, what the technical solution of the utility model was realized in：
The bricklayer of submersible electric pump Internal hole positioning type last item has, including cylindric press fitting bar, which includes compression bar
Location division and the bearing shell location division of compression bar location division one end connection, the compression bar location division and bearing shell location division are coaxially disposed,
The endoporus aperture that face bearing shell mounting hole opens up in compression bar location division diameter and submersible electric pump is correspondingly arranged, compression bar positioning
Minister's degree is set more than the submersible electric pump interior hole length, bearing shell location division diameter and Pad radius to be pressed.
Further, transition part is equipped between the compression bar location division and bearing shell location division, transition part is cylindric, transition part
Diameter is between compression bar location division and bearing shell location division diameter.
Further, bearing shell location division length and bearing shell width to be pressed are correspondingly arranged.
Further, the compression bar location division is being equipped with protection portion away from one end of setting bearing shell location division.
Further, the protection portion is cylindric that the protection portion and compression bar location division are coaxially disposed, and the protection portion is straight
Footpath is less than compression bar location division diameter.
Relative to the prior art, submersible electric pump Internal hole positioning type last item bricklayer tool described in the utility model has following excellent
Gesture：
In submersible electric pump Internal hole positioning type last item bricklayer tool described in the utility model, compression bar location division and bearing shell location division
It is coaxially disposed, the endoporus aperture of compression bar location division diameter and bearing shell pedestal is correspondingly arranged, and bearing shell location division diameter and treats Fitted Axles
Watt internal diameter is correspondingly arranged, therefore when being pressed, be make use of the guidance quality of pedestal endoporus itself, ensured compression bar location division movement straight line
Property, thereby ensure that bearing shell and bearing shell mounting hole to be pressed to neutrality, is avoided because bearing shell to be pressed and bearing shell mounting hole are to neutrality
The generation of bearing shell pressure break phenomenon caused by poor.
