Abstract

The invention discloses an engine crankshaft oil seal press-fitting tool, belongs to the field of crankshaft press-fitting, and solves the problem that traditional crankshaft oil seal press-fitting ishigh in labor intensity and low in efficiency. The engine crankshaft oil seal press-fitting tool comprises a pressure head and a positioning sleeve arranged in a split manner, wherein a mounting basefor mounting a crankshaft oil seal is arranged at one end of the pressure head; a press-fitting surface is formed between the mounting base and the pressure head; a guiding annular surface, an oblique annular surface and a positioning annular surface are sequentially arranged on the outer surface of the positioning sleeve in the axial direction of the positioning sleeve; the diameter of the guiding annular surface is less than the internal diameter of the axle hole of an oil seal seat; the diameter of the positioning annular surface is matched with the diameter of a crankshaft large head; anda positioning shaft matched with the axle hole of the crankshaft large head is arranged in the center of the positioning sleeve on one side of the positioning annular surface. The invention further discloses an engine crankshaft oil seal press-fitting method. The engine crankshaft oil seal press-fitting tool and method can effectively lower the labor intensity and improve the working efficiency while meeting the oil seal sealing requirement.

Description

technical field [0001] The invention relates to the field of crankshaft oil seal press-fitting, more specifically, it relates to an engine crankshaft oil seal press-fit tooling and method. Background technique [0002] Crankshaft oil seal press-fitting is an essential process in the engine assembly process. Improper crankshaft oil seal press-fitting will cause problems such as oil seal failure and engine oil leakage. For the press-fitting of the crankshaft oil seal, the traditional operation method is to manually squeeze the oil seal seat into the oil seal seat, and then put the oil seal seat on the big head of the crankshaft to complete the installation of the crankshaft oil seal. The traditional crankshaft oil seal installation method is labor-intensive and has low work efficiency, which is difficult to meet the rapid development needs of enterprises. Contents of the invention [0003] The technical problem to be solved by the present invention is to address the above-m...
