Abstract

The invention provides a tool and a method for pressing a dustproof oil seal in a blind hole of a steering gear. The tool comprises a vertically arranged pressing shaft, the upper end of the pressingshaft is movably sleeved with a connecting plate, the lower end of the pressing shaft is movably sleeved with and slidably fit with a sealing sliding sleeve, and a sealing device is arranged at a lower end port of the sealing sliding sleeve; the middle of the pressing shaft is movably sleeved with a compression spring, and two ends of the compression spring abut against the pressing shaft and thesealing sliding sleeve respectively; a guide device is fixedly arranged on the pressing shaft, and is located below the connecting plate, and the pressing shaft and the sealing sliding sleeve are linked with the guide device in the vertical direction; an accommodating groove is formed in a lower end face of the pressing shaft, and an air exhaust channel communicating with the accommodating grooveis arranged in the pressing shaft. The sealing sliding sleeve is matched with the pressing shaft, so that the blind hole is subjected to negative pressure pumping, and then the dustproof oil seal is installed in the blind hole, the structure is simple, and operation is convenient; and by pressing of the dustproof oil seal in the blind hole, pressing is convenient, deviation is less likely to occur, and the dustproof oil seal is prevented from rebounding.

Description

technical field [0001] The invention relates to the technical field of automobile power steering gears, in particular to a tooling and a method for press-fitting a dustproof oil seal into a blind hole of the steering gear. Background technique [0002] In the structure of the recirculating ball steering gear, the function of the dust-proof oil seal is to prevent external foreign matter from entering the steering gear, thereby causing corrosion to the sealing part. In order to facilitate the detection of the leakage performance of the steering gear during the test, the dust-proof oil seal is usually installed at the end after the steering gear has passed the test. If the installation is not in place, the dustproof effect will be invalid. Contents of the invention [0003] Aiming at the problems in the prior art, the present invention provides a tool and method for press-fitting a dustproof oil seal into a blind hole of a steering gear. [0004] A tool for press-fitting a ...
