The application discloses an assembled self-resetting energy dissipation bridge block, which comprises a block, wherein the block is connected to the outrigger of the cap beam on both sides through prestressed reinforcement, a damper is connected between the side surface of the block and the side surface of the cap beam body, a rubber pad is connected to the upper part of the side surface of the block, and the rubber pad is arranged on the side surface of the beam body above the cap beam. The assembled block is used to replace the fixed block, the block is arranged at the outrigger of the cap beam, the block and the outrigger of the cap beam are connected through the prestressed reinforcement, a disc spring is arranged at the top end anchoring position of the prestressed reinforcement, the tensioning of the prestressed reinforcement is realized, the installation stability of the block is ensured, the lower part of the side surface of the block is connected to the cap beam body through the U-shaped damper, and the rubber pad is arranged on the upper part of the side surface of the block. The transverse displacement of the block is effectively reduced, the damper can drive the block to reset, the residual deformation caused by vibration is reduced, the impact of the upper beam body structure on the block is buffered, and the self-resetting capacity of the whole anti-seismic block system is improved.

This application provides a fixture and method for clamping and machining thin-walled welded parts, relating to the field of fixture and tooling technology. The fixture includes a base mechanism, a central positioning mechanism, an angular positioning structure, an auxiliary support mechanism, and a clamping mechanism. The base mechanism uses a disc and multiple circumferentially arranged elongated plates to form a support surface; the central positioning mechanism mates with the positioning inner hole of the part to achieve central positioning; the angular positioning structure mates with the angular hole of the part to achieve angular positioning; the auxiliary support mechanism is set for each lug to be machined, using V-shaped supports and lateral limiting components to provide auxiliary support and limit the lugs to be machined; the clamping mechanism clamps the part to the clamping reference surface. This solution can improve the clamping stability, positioning accuracy, and local rigidity during machining of thin-walled welded parts, reduce vibration and lateral displacement of the lugs to be machined, and reduce the risk of cracking at the weld joint.
