摘要:
The invention relates to a device for receiving a workpiece in a bearing device for rotatably mounting the workpiece about a bearing axis (L) associated with a workpiece bearing surface. The device comprises a bearing pedestal (14) including a bearing element (1) which has two concavely cylindrical bearing surfaces (5, 6) that lie next to one another in the same bearing plane and symmetrically to a plane of symmetry containing the bearing axis (L), the cylinder radii of the cylindrical bearing surfaces being greater than the radius of the workpiece bearing surface for which the bearing device is intended, wherein the cylinder axes of the two bearing surfaces (5, 6) are parallel to the bearing axis (L) and have a distance between each other.

Apparatus for clamping a piece, includes a frame portion adapted to be fastened to a base, a fastening clamp fitted to foe frame portion having first and second jaw components on the opposite sides and a wedge member fitted therebetween, fixing stopper. The piece is adapted to be clamped between the first jaw component of the fastening damp and the fixing stopper. An arrangement is disposed between the second jaw component of foe fastening clamp and the fixing stopper, functionally connecting these to each other, for moving the fixing stopper by way of the fastening clamp. In addition, the apparatus is related to a fastening device, a method and a system for clamping a piece as well as a fastening clamp for a fastening device.

The invention relates to a device (1) and a method, comprising a workpiece-receiving portion (2) for receiving a workpiece (28) to be mechanically machined. At least one vibrating device (9) is connected to the workpiece-receiving portion (2), and the vibrating device (9) causes the workpiece-receiving portion (2) to vibrate, the vibration of the workpiece-receiving portion (2) having a frequency that is lower than the frequency of ultrasound. The vibrating device (9) has a vibrating body (8) to which a compensating mass (7) that vibrates in the opposite direction is associated.

A transfer apparatus for permitting ease of movement of a workpiece across an operating surface of a table where the table includes a plurality of slots. Mounted within each slot is a rail member. Mounted within each rail member is a plurality of rolling members. The rail member is to be vertically movable within its respective slot so as to have the rolling members be totally confined within the rail member or have the rolling members protrude from the upper surface of the rail member. The rail member includes a plurality of pistons which are mounted within cylinders. Air pressure is to be supplied to each of the cylinders which is to cause the rail member to be moved vertically in an upward direction and cause the rolling members to protrude above the working surface of the table so that a workpiece can be completely supported by the rolling members and be spaced from the working surface of the table.
摘要:
A propeller positioning device comprises a table mount comprising a base member of substantially cylindrical configuration having an under surface substantially perpendicular to the axis thereof and an upper surface transverse to the axis thereof. A table has a substantially planar upper surface, an under surface and a substantially cylindrical support member coaxially affixed to the under surface thereof and having a substantially planar under surface transverse to the axis thereof. A rotating device rotatably mounts the support member on the base member in a manner whereby the under surface of the support member rests on the upper surface of the base member and the support member is rotatable about an axis of rotation perpendicular to the under surface of the support member and the upper surface of the base member so that the table assumes different inclinations corresponding to the rotation of the support member on the base member. A spindle for accommodating a propeller is affixed to the upper surface of the table and extends perpendicularly therefrom and coaxially with the support member.
