Problems solved by technology

[0003] At present, friction welding usually uses a special friction welding machine, which occupies a large area and has high cost. For fields that require machine tool processing, a special friction welding machine is also required when friction welding is involved, resulting in high cost and workpieces. After welding, the welding machine needs to be transferred to the machine tool, which increases the clamping times of the workpiece and easily reduces the precision of the workpiece processing

Abstract

The invention discloses a method for performing friction welding by utilizing a machine tool, and relates to the field of machine tool equipment. The method aims to solve the problem that the occupiedspace of traditional friction welding is large. According to the technical scheme, the method comprises the following steps that S1, all shafts go back to original points, and two to-be-welded partsare clamped on the main shaft and the auxiliary shaft correspondingly; S2, the main shaft rotates, and meanwhile, the auxiliary shaft is rotated and locked; S3, the auxiliary shaft is moved and positioned, and an auxiliary table drives a pushing block to move to be in contact with the pushing plate; S4, the auxiliary shaft and a tool turret move at the same time and drive the to-be-welded parts tomove to a mutual contact state, and friction heating is achieved; and S5, the rotating speed of the main shaft is reduced to be zero, a first three-jaw chuck loosens the workpiece, and meanwhile, theauxiliary shaft drives the workpiece to return. The method for performing friction welding by utilizing the machine tool has the advantage of less workpiece clamping frequency.

Description

technical field [0001] The invention relates to the technical field of machine tools, in particular to a machine tool and a friction welding method using the machine tool. Background technique [0002] Friction welding is a solid-state welding method. The friction welding machine uses frictional heat as the heat source to generate heat on the friction surfaces of the two weldments through mechanical friction movement and axial pressure, thereby heating the friction surfaces of the two weldments. to plastic deformation, and then use plastic deformation to firmly connect two weldments of the same material or dissimilar materials. [0003] At present, friction welding usually uses a special friction welding machine, which occupies a large area and has high cost. For fields that require machine tool processing, a special friction welding machine is also required when friction welding is involved, resulting in high cost and workpieces. After welding, the welding machine needs to...
