Problems solved by technology

[0003] Although the entire assembly work is simple, the flatness of the rear oil seal cannot be detected after assembly. The unqualified flatness of the rear oil seal is one of the reasons affecting the oil leakage of the rear oil seal of the engine. In addition, the pressing force of the rear oil seal cannot be monitored. If the rear oil seal Insufficient interference with the rear oil seal seat will cause the rear oil seal to break out

Abstract

The invention discloses an oil seal press-fitting device. The oil seal press-fitting device comprises a workbench used for allowing a workpiece to be contained, an oil seal pressing head capable of moving up and down is arranged above the workbench, an inserting connection port is arranged on the oil seal pressing head and is used for allowing an oil seal to be installed, a positioning block capable of moving up and down is arranged below the workbench, and the axis line of the oil seal pressing head, the axis line of the positioning block and the axis line of an oil seal hole of the workpiececoincide; the oil seal press-fitting device further comprises a plane detection mechanism and a conveying mechanism, wherein the plane detection mechanism is located above the workbench and is used for detecting the flatness of the oil seal, and the conveying mechanism is used for conveying the workpiece to the position below the plane detection mechanism. According to the oil seal press-fittingdevice, the press-fitting force and the stroke of the oil seal can be monitored in real time, moreover, the flatness of the oil seal after press-fitting can be detected, the press fitting quality of the oil seal is ensured, and the faults of oil seal oil leakage and oil seal loosening are avoided, and the situation of a large amount of cost caused by reworking of an engine is avoided.

Description

technical field [0001] The invention relates to the technical field of oil seal press-fitting, more specifically, it relates to an oil seal press-fitting device. Background technique [0002] During the diesel engine assembly process, the rear oil seal process requirement of the crankshaft is generally to seal the crankshaft rear oil on the rear oil seal seat in advance, and then assemble the rear oil seal seat and the rear oil seal on the crankshaft during the engine assembly. The existing crankshaft rear oil seal assembly process is mainly to manually adopt the iron bell and the rear oil seal assembly tool and assemble it by manual hammering. The specific process operation is: manually place the crankshaft rear oil seal in the installation hole of the rear oil seal, and adjust the The rear oil seal is coaxial with the rear oil seal seat, then lightly tap the outer ring of the rear oil seal with an iron bell to make the rear oil seal enter the rear oil seal seat, and finall...
