Claims

[Scope of utility model registration request]

□ Main and sub arms connected so that their lower ends can be opened and closed in a vertical plane, a pair of upper and lower receiving rolls attached to the lower end of the main arm, and a pair of upper and lower receiving rolls attached to the sub arm facing the both receiving rolls. In a crankshaft pin deep roll device in which a roll unit including a push roll is installed at each pin city bank of the crankshaft, when the corresponding pin part comes into contact with the pair of upper and lower receiving rolls 1 and 2, the pin part Each main arm 5 is provided with an upper hook 3 that substantially engages with the upper hook 3, and a lower slope 4 capable of guiding a pin portion into the upper hook, and when both the main and sub arms are opened, the upper hook or the lower slope is connected to the lifter 6. The upper end of each main arm 5 is suspended and supported by a balancer 8 attached to the machine frame 7 so as to intersect with the locus of the crank motion pin part that is pushed up, and the lower end of the main arm is cranked relative to the machine frame. A sliding coupling mechanism 9, 10 is provided between the upper part of the main arm and the machine frame so that each pin of the crankshaft engages with the hook 3 of the corresponding roll unit, or when the phthalo is in the raised position. ,
A deep roll device for a crankshaft pin portion, characterized in that a rotation drive device to which the crack shaft is connected is attached to the mechanism 7.
