Abstract

The invention discloses an oil seal pressing mechanism for a vehicle crankshaft. The mechanism comprises a crankshaft; an oil seal mounting shaft is formed at one end of the crankshaft; a center hole is formed in the upper end surface of the oil seal mounting shaft; the upper end surface of the oil seal mounting shaft butts against a conical positioning base; a conical dowel pin is formed on the lower end surface of the positioning base, and is inserted in the center hole of the oil seal mounting shaft; a pressing table is formed on the upper end surface of the positioning base; the lower end surface of the oil seal mounting shaft butts against a similarly C-shaped limiting bracket; upwards vertical screw rods are formed at four corners of the limiting bracket; insertion grooves are formed in the inner sides of the screw rods; 1 / 4 circular pressing rings are inserted in the insertion grooves; arc racks extending up and down are formed in the side walls of the pressing rings in the insertion grooves, and are engaged with adjusting gears; and pressing rods are formed on the side walls of the pressing rings opposite to the arc racks. The mechanism can conveniently and quickly mount an oil seal at a large end of the crankshaft, and can prevent damage of the oil seal.

Description

Technical field: [0001] The invention relates to the technical field of automobiles, in particular to an oil seal pressing-in mechanism for an automobile crankshaft. Background technique: [0002] The crankshaft is an important part of the alcohol engine. The rear oil seal of some BT models is embedded in the flywheel housing and the big end of the crankshaft (ie figure 1 In the oil seal installation shaft 11) in the installation and leak repair, if there is no suitable installation device, the oil seal is knocked in only by impact force, and the oil seal is easily deformed after being subjected to unilateral impact force, which will damage the sealing rubber , causing the oil seal to be damaged and scrapped. [0003] In view of the above-mentioned defects, the designer actively researches and innovates, in order to create a new type of structure for the oil seal press-in mechanism of the automobile crankshaft, so that it has more industrial utilization value.
