Abstract

The invention provides a double-sealed rear oil seal tool, and belongs to the technical field of tools. The double-face sealing rear oil seal tool comprises a tool assembly and a buffering assembly. An impact part is fixed to one side of a press-fitting part, a circular groove is formed in the other side of the press-fitting part, a transition fillet is formed in the edge of the circular groove, and a limiting ring sleeve is concentrically fixed to the bottom of the circular groove; one end of a first elastic part is connected with a sliding sleeve, and the other end of the first elastic part is fixedly connected with the impact part; and oil seal after double-face sealing is arranged at the head of the press-fitting part, the impact part is fixed to one side of the press-fitting part, then the impact part is beaten through a steel hammer, the limiting ring sleeve is used for limiting, and the press-fitting part can be obtained after beating in place; the edge of the circular groove is provided with the transition fillet, so that the transition fillet is increased, stress is dispersed, and the service life is prolonged; and the circular groove is formed in the other side of the press-fitting part, the limiting ring sleeve is concentrically fixed to the bottom of the circular groove, and the outer diameter of the limiting ring sleeve is matched with the inner diameter of the oil seal.

Description

technical field [0001] The invention relates to the technical field of tooling, in particular to a double-sided sealed rear oil seal tooling. Background technique [0002] Currently, various proposals have been made regarding engine oil seals for automobiles. As an oil seal used in an engine, the oil seal has a sealing lip made of an elastomer composition consisting of acrylic rubber (ACM), fluororubber ( FKM), nitrile rubber (NBR), urethane rubber (U), silicone rubber, hydrogenated nitrile rubber and their blends and other elastomers and silicic acid compounds; [0003] Conventional engine oil seals are single-sided seals. After installation, the oil seals are single-sided sealed oil seals. Now they are changed to double-sided seals. The original manual oil seal installation tool is not suitable for double-sided sealed oil seals. The impact generated by the impact on the hand-held part is easy to injure the hand, and there is a potential safety hazard. Contents of the in...
