Title:
TWO-DIMENSIONAL TILTING CAP
Document Type and Number:
Japanese Patent JP2007307648
Kind Code:
A
Abstract:

To obtain a cap tilting in a two-dimensional direction, which is attached to a vice to be used for holding a work, manufactured easily, thinned down, and excellent in durability at the time a holding reaction force in a lateral direction is applied thereon repeatedly.

A truncated semispherical body 2 having its truncated surface as a work holding surface 6 and a mounting base body 1 are provided. Between this truncated semispherical body 2 and the mounting base body 1, an uneven spherical surface having the spherical center of the truncated semispherical body 2 as its center is provided, and it is face-contacted in a freely slidable manner. That enables the tilting of the work holding surface 6 in this two-dimensional tilting cap. The recessed portion 5 of the spherical surface forming the recessed spherical surface is formed on the top of a supporting protrusion 4 protruded inside the mounting base body 1, and a semispherical protrusion 7 forming the protruded spherical surface is protruded in the center on the opposite side of the holding surface of the truncated semispherical body 2.
