Claims

[Scope of utility model registration request]

It is equipped with a drive unit that moves forward and backward toward the front jig stand that holds the crankshaft, and also has a processing unit that performs super-finishing on the pins, journals, and other parts of the crankshaft.Multiple processing heads can be moved freely on rails. and a portion of the rail located in front of the drive unit is constituted by a movable rail that moves forward and backward along with the drive unit, and any one of these machining heads is selectively moved to the movable rail. The machining head is moved forward together with the drive unit to perform super finishing machining on the crankshaft, and each of the machining units is configured to be hydraulically actuated by a hydraulic motor, hydraulic cylinder, or other hydraulic actuator. Furthermore, each processing head is provided with a hydraulic pump that supplies pressure oil to the hydraulic actuator, and a coupling on the rear side that is connected to an oil tank and a drive shaft provided on the front side of the drive unit to transmit power to the hydraulic pump. At the same time, each processing head is equipped with an air-operated control unit that controls the operation of each processing unit, and each processing head is equipped with an air-operated control unit that controls the operation of each processing unit, and each processing head is connected to an air supply port provided on the front side of the drive unit. A crankshaft super finishing device characterized by supplying air through an air joint on the back of a processing head.
