摘要： [Problems]A gripping method for a turbocharger housing and a work gripping device that can accurately grip an inner diameter using a reference for shape during casting when processing.[Means for Solving Problems]In a gripping method of a turbocharger housing W, an end surface Y of a large diameter hole 22 facing a small diameter hole 25 is used for positioning in an axial direction. The inner diameter of the large diameter hole 22 is then gripped. A work gripping device 1 includes a cylindrical body 2, a plunger 3 that moves back and forth along an axial direction of the body 2, a jaw 4 that moves in a radial direction of the body 2 in tandem with the plunger 3, and a pusher 6 that presses the work W in a direction away from the body 2 in accompaniment with movement of the plunger 3. The jaw 4 includes a gripping surface 24 that grips the work W and a contact surface 5 that projects in an outward radial direction from an end edge of the gripping surface 24 away from the body 2. The pusher 6 presses the work W to the contact surface 5 and the work W is gripped.

摘要： A gripping method for a turbocharger housing used to process a turbocharger housing formed by casting, includes a scroll formed in a spiral shape from an axial center, and a large diameter hole and a small diameter hole provided along an axial direction of the scroll with space therebetween, such as to face each other. After positioning of the turbocharger housing is performed using an end surface of the large diameter hole facing the small diameter hole as a reference surface for positioning in the axial direction, an inner diameter of the large diameter hole is gripped.
