Seal ring installation device and method

Abstract

The invention relates to the technical field of press fitting, and discloses a seal ring installation device. The seal ring installation device includes an installation main body, a height regulatingunit and a lock nut, a seal ring can be arranged in a seal ring installing groove in a press fitting mode through the installation main body, and the periphery surface of the installation main body isprovided with an external thread; the height regulating unit is located below the installation main body, the height regulating unit includes a regulating sleeve, and a thread of the regulating sleeve is connected to the periphery surface of the installation main body; and a thread of the lock nut is connected to the periphery surface of the installation main body, and the end face of one end ofthe lock nut abuts against the end face of one end of the regulating sleeve. The height of the seal ring installation device can be regulated through the height regulating unit to be matched with sealring installing grooves with various heights, and the installing operations of the seal rings with various heights can be achieved. The invention further discloses an installation method adopting theseal ring installation device, a plurality of seal rings can be stored at a time, and continuous, multiple and ceaseless installing operations can be achieved.

Description

technical field [0001] The invention relates to the technical field of press-fitting, in particular to a sealing ring installation device and installation method. Background technique [0002] In order to ensure the normal operation of the engine, it is necessary to prevent oil leakage from the cylinder head, so it is necessary to install an O-ring at the bottom hole of the injector of the cylinder head, which requires high requirements for the installation and operation of the seal ring. However, the sealing ring groove is located inside the bottom hole of the injector, and due to the position limitation, the installation operation of the sealing ring is difficult and the efficiency is low. [0003] The existing sealing ring installation device uses a shift fork to perform circular motion along the annular gap, and dials the sealing ring into the annular groove of the cylinder head, which can eliminate the phenomenon that the sealing ring does not completely enter the annul...

AI Technical Summary

Problems solved by technology

However, the height of this kind of sealing ring installation device cannot be adjusted, and it is difficult to realize the installation operation of different heights. In addition, this kind of sealing ring installation device can only install one sealing ring at a time. After each installation, the sealing ring needs to be taken again for installation. more laborious

[0004] Therefore, it is necessary to propose a sealing ring installation device and an installation method to solve the problem that the installation height of the existing sealing ring installation device cannot be adjusted
