Impeller pressing fixture

Abstract

The invention relates to an impeller pressing fixture, which comprises a main cylinder, a rack body, an upper fixture and a lower fixture, wherein the main cylinder is installed on the upper part of the rack body; the upper fixture comprises a connecting plate, a first positioning plate, a gland nut, a plug screw, a first spring, a pressure head, a core print, a second spring, a first steel ball, an upper limited post and a second steel ball; the lower fixture comprises a platen, a first limited post, a stand post, a screw, a positioning sleeve, a fixture body, a top core, a central spindle, a polyurethane elastomer, a first ash damper, a wedged pad iron side plate, a base plate, a second positioning plate, a bottom plate, wedged pad iron, a second connecting rod, a bracket, an auxiliary cylinder, a guide post, a guide sleeve, a second ash damper, a second limited post and a pad post. The impeller pressing fixture has the advantages of reliable clamping mode, good stability, high automation degree, convenience in operation, manpower saving and the like, an impeller can be quickly assembled, assembling efficiency is improved, damage to a water pump bearing by impact force can be avoided, and the water pump bearing can be prevented from dislocating and falling so as to guarantee that impeller assembling and processing can be successfully carried out.

Description

technical field [0001] The invention relates to the field of automobile clamps, in particular to a clamp for impeller pressing. Background technique [0002] The impeller refers to the disc equipped with moving blades, which is an integral part of the impulsive steam turbine rotor. It also refers to the general term for the wheel disc and the rotating blades installed on it. After the impeller is processed, it must be pressed into a specific position of the water pump through a specific fixture or method. [0003] Chinese patent application publication CN101408202A discloses a water pump impeller press-fitting device and its press-fitting method. The water pump impeller press-fitting device has a support plate, and it is characterized in that four guide columns are arranged on the support plate, and each guide column A support spring is set on the outside of the guide column, and a positioning plate is set on the guide column. The support spring is located between the supp...
