Abstract

The utility model relates to a housing processing tool provided with a stator. The housing processing tool comprises an expansion core, an expansion sleeve, the stator and a processed housing, wherein the expansion sleeve comprises a fixing part and a working part; a through hole is formed in the center of the expansion sleeve; the expansion core penetrates through the through hole to be connected with the expansion sleeve; the stator is nested at the working part of the expansion sleeve; the processed housing is nested outside the stator; and the expansion sleeve and the expansion core relatively rotate. According to the housing processing tool, firstly, the stator is nested in the housing, then, a seam allowance is processed after the inner circle of the stator is positioned, and the processed seam allowance in the housing cannot deform due to the fact that the housing is supported by an outer circle of the stator, so that the circular degree and the axial coaxiality of the seam allowance of the housing provided with the stator are guaranteed, the qualified rate is increased after a water pump is assembled, noise is reduced, clamping and scraping of an impeller and the pump body are avoided, and the use reliability of a product is improved.

Description

A kind of casing processing tool with stator

Technical field

The utility model relates to water pump and manufactures field, particularly relates to a kind of casing processing tool with stator.

Background technology

With casing stator, be the critical component of water pump product, its seam cylindrical directly affects reliability and the overall mass of product on the axiality of axis.Gently cause impeller scraping, noise to increase, heavy cannot startup, impeller and the pump housing block, thereby motor damage cannot be worked.Traditional processing technology is to be pressed into stator after casing processing, and casing processing is with casing internal diameter location, and is pressed into after stator, and circularity and axiality with its stator inner circle of casing stator just cannot guarantee.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of casing processing tool with stator, for guaranteeing circularity with casing stator seam and the axiality to axis, after water pump assembling, qualification rate improves, reducing noise, and avoided the stuck of impeller and the pump housing and scraping, improved the reliability that product is used.

The utility model solves the technical scheme that its technical problem adopts: a kind of casing processing tool with stator is provided, comprise the core that rises, ringfeder, stator and processed casing, described ringfeder comprises fixed part and operate portions, its center location arrangements has a through hole, the described core that rises is connected with ringfeder through through hole, described stator sleeve is connected on the operate portions of ringfeder, and described processed casing is socketed in stator outside, and described ringfeder and the core that rises relatively rotate.

The fixed part bilateral symmetry of described ringfeder is provided with screw and is connected with base.

An inclined hole groove is arranged at described ringfeder bottom, and there is a hole slot described inclined hole groove inside, and bearing is equipped with in described hole slot inside.

It is cylindrical that the described core that rises is ladder, and there is a taper hole groove the described core one end of rising, in described taper hole groove, is connected with top, is socketed with bearing, and is connected with the hydraulic mechanism of base inside on the described core that rises without one end of taper hole groove.

Between described stator one side and the fixed part of ringfeder, locating bar is installed.

beneficial effect

The utility model relates to a kind of casing processing tool with stator, first in casing, be inserted in stator, then with the technique of processing seam behind stator inner circle location, because casing is subject to the support of stator cylindrical, processing back cabinet seam can not be out of shape, thereby guarantee circularity with casing stator seam and the axiality to axis, after water pump assembling, qualification rate improves, reducing noise, and avoided the stuck of impeller and the pump housing and scraping, improved the reliability that product is used.
