Abstract

An inertia friction welding clamping mechanism for a front drum of an engine adopts a clamping structure way of combining a mechanical and hydraulic system with low-temperature grease expanding mechanism; a tailstock clamp is used for clamping a processed part and adopts a mechanical clamping structure with an inner cone and an outer cone; in order to enhance the welding reliability, an elastic half ring is adopted at the part welding part to tighten the processed part to enhance the strength to control the part welding deformation; and a main shaft clamp adopts a low-temperature grease expanding mechanism, seals a sealing structure applying an O-shaped seal ring and a semi-circular arc-shaped seal rubber ring accordingly, and is meshed with equipment coil circuit connector correspondingly. The friction welding clamping mechanism improves the rotor connector quality and the production efficiency remarkably, ensures the processing precision of the part and the service life of the friction welding clamping mechanism, reduces the manufacturing cost of the tool, improves the tool using reliability, and meets the production filed and process requirements.

Description

technical field [0001] The invention relates to the technical field of structural design and application of inertial friction welding fixtures, and in particular provides a clamping mechanism for inertial friction welding of an engine front drum. Background technique [0002] The process of inertia friction welding is to accelerate the main shaft with flywheel and parts to the required speed, and then under the action of welding pressure, push the parts on the non-rotating tailstock to the parts on the main shaft to make them contact and generate friction. As the process progresses, the spindle speed is continuously reduced, converting the kinetic energy stored in the flywheel into thermal energy, which heats the welding surface. As the temperature rises, the welding surface continuously produces adhesion and shearing. When the welding surface is heated to a plastic state and the adhesion strength of the entire welding surface is greater than the shearing strength, the spind...
