Abstract

The invention discloses a novel linear friction welding device. The device comprises a base and a supporting frame. The supporting frame is movably arranged on the upper end face of the base, a vibration mechanism, a dual-cam mechanism and a feeding mechanism are included, during welding, through the vibration mechanism, a workpiece to be welded is driven to do up and down reciprocated type motion, the dual-cam mechanism drives a workpiece to be welded to do left and right reciprocated type motion, the feeding mechanism drives the two welded workpieces to oppositely move, and the welding process is finished. The up and down vibration amplitude of the workpieces to be welded is adjusted through a planetary phase conversion mechanism, relative rest of the workpieces to be welded can be achieved, mismatch appearing in the workpieces to be welded after emergency stop can be avoided, and the dual-cam structure is adopted for driving the workpiece to be welded to do left and right reciprocated motion.

Description

technical field

[0001] The invention relates to the technical field of welding devices, in particular to a novel linear friction welding device. Background technique

[0002] Linear friction welding Linear friction welding technology, as a new, high-quality, efficient and environmentally friendly solid-phase connection technology, has achieved great success in the manufacture and maintenance of aero-engine blisks. As a welding method with great potential application prospects, the reason why it has not been widely used after nearly 20 years of development is that the equipment of linear friction welding machine is expensive, and with the increase of reciprocating motion frequency, the energy consumed increases sharply, and the external The requirements for the installation are extremely high. Contents of the invention

[0003] The problem to be solved by the present invention is to provide a new type of linear friction welding device, which changes the amplitude of the up...
