    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 jaw chuck provided with an inner sleevelike housing which, at its forward end, is provided with radially extending T-shaped slots which slidably accommodate the jaw carriers. The inner housing is totally surrounded and fixedly connected to an outer sleevelike housing which overlaps the outer ends of the slots. A push-type activator is disposed adjacent the rearward end of the inner housing and is axially slidable relative thereto. This activator includes wedges which project axially forwardly and are slidably and wedgably engaged with the jaw carriers for effecting radial displacement thereof. The wedges have the outer peripheries thereof axially slidably supported on the inner periphery of the outer housing.

    摘要： The invention provides a chuck including a plurality of jaws (8), each of which is fixed to the forward end of a jaw carrier arm (5), said arm (5) being borne by a pivot joint (6) mounted on the body (1) of the chuck and the rotation of which imparts to the jaw (8) an essentially radial movement, said rotation being controlled by radially displacing a sliding member (4) pushing a truncated sphere (10) housed between said sliding member (4) and a recess provided in the arm (5) to the rear of said pivot joint (6). Furthermore, said truncated sphere (10) is capable of sliding over the plane surface of contact with the sliding member (4), said jaw carrier arm (5) then sliding in the pivot joint (6) in an essentially axial direction, while being drawn rearwards by a return spring (7). Application to the clamping of a piece while pressing it axially against its stops.
