Abstract: A vibration absorber includes a screw, a displacement adjustment member, a first spring, a second spring, a mass block, a casing, a cover and a connector. The displacement adjustment member is engaged with the screw. The mass block is located between the first spring and the second spring, wherein the mass block respectively connects the first spring and the second spring on both sides and the screw passes through the mass block. The casing encloses the screw, the displacement adjustment member, the first spring, the second spring and the mass block. The cover covers one opening of the casing. The connector covers the other opening of the casing. The first spring is located between the mass block and the displacement adjustment member and connects respectively the mass block and the displacement adjustment member. The coefficients of elasticity of both the first spring and the second spring are both non-linear.

Abstract: A clamping device includes a first holder and a second holder. The first holder includes a first abutting member and a driving member. The driving member is coupled to the first abutting member. The second holder includes a second abutting member. The first abutting member and the second abutting member are oppositely disposed and spaced apart from each other to receive a workpiece. The driving member is coupled to the first abutting member to drive the first abutting member to move in a direction toward the second abutting member to clamp the workpiece between the first abutting member and the second abutting member.

Abstract: A fixture for a thin-walled workpiece includes two clamping devices. Each of the clamping devices has a metal carrier and a damper. The metal carrier has a carrying portion and a supporting portion, where the supporting portion has a stair portion having a plane surface and a standing surface with a slope. The damper has a metal clamping portion and a damping portion. One end of the metal clamping portion is formed as an inclined surface. The damping portion has at least two elastic layers and at least one metal layer, which are laminated in an interlacing arrangement with the same slope of the inclined surface. One of the elastic layers is disposed to connect the inclined surface. The end of the metal clamping portion connecting the elastic layer is located on the stair portion, while the opposite end of the metal clamping portion protrudes out of the supporting portion.
