Tool and method for assembling shock absorber

Abstract

The invention discloses a tool and a method for assembling a shock absorber. The tool comprises a guiding sleeve and a centering locking component which is used for coaxially communicating a barrel of the shock absorber with the guiding sleeve and connecting the barrel of the shock absorber with the guiding sleeve in a sealed manner; the tool further comprises a press head which is used for pushing a piston component and an oil seal assembly of the shock absorber to axially move along the inside of the guiding sleeve and enabling the piston component and the oil seal assembly to be press-fitted in the barrel finally; and a gas inflation hole for introducing gas and an oil injection hole for injecting hole are formed in the guiding sleeve. Air in a liquid chamber of the barrel of the product can be exhausted in the assembling process, the indication idle stroke can be eliminated, the performance of the product can be improved, the structure of the product can be optimized, the machining difficulty of parts can be reduced, the machining efficiency can be improved, meanwhile, the product is not required to be circulated back and forth, and the transport cost is reduced while the production cycle is shortened.

Description

technical field [0001] The invention relates to the field of shock absorber assembly, in particular to a shock absorber assembly tool and an assembly method thereof. Background technique [0002] Existing automobile shock absorbers with gas compensation, when assembling, the inflation and oil injection assembly processes are all carried out manually. Press the guide seat and install the retaining ring. After this series of oil injection procedures are completed, open a hole on the oil storage tank cover to inflate, and finally seal it with rivets. The disadvantage of this method is that the air in the liquid chamber of the cylinder cannot be exhausted, and the dynamometer diagram shows that there is a void, which affects the product performance, and makes the final product complex in structure, with many parts, long production cycle, and high transportation and turnover costs. [0003] Therefore, it is necessary to improve the existing assembly method of the shock absorber....
