Embodiment Construction

[0039] Such as figure 1 As shown, a friction welding axial deformation accuracy control process is characterized by:

[0040] (1) Automatic measurement of the axial dimensional accuracy of the rotating workpiece 1 and the moving workpiece 2: input the axial dimensions of the rotating workpiece 1 and the moving workpiece 2 of standard size into the friction welding control system 9, and the rotating workpiece 1 of the standard size is clamped in The rotating piece fixture 3.2, the moving workpiece 2 is clamped in the moving piece fixture 4.2, and the welding loading mechanism 5 pushes the moving slide system 4.1, the moving piece fixture 4.2 and the moving workpiece 2 to walk in the direction of the rotating workpiece 1 until the rotating workpiece 1 and the moving workpiece 2 close contact, the displacement sensor 7 records the position data after the close contact between the rotating workpiece 1 and the moving workpiece 2, and transmits the position data to the friction weld...

Abstract

The invention relates to a friction welding axial deformation precision control process. The friction welding axial deformation precision control process includes a rotating workpiece 1, a moving workpiece 2, a spindle system 3.1, a rotating member fixture 3.2, a moving sliding table system 4.1, a moving member fixture 4.2, a welding loading mechanism 5, a lathe bed 10.1, a guide rail moving pair10.2, a power-driven system 11, a hydraulic system and connecting line 12, a torque sensor 6, a displacement sensor 7, a pressure sensor 8 and a friction welding control system 9. Based on friction torque jump / axial welding pressure jump determination conditions, the problem of automatic measurement of workpiece axial dimensional precision in the welding preparation process and the problem of accurate compensation of the spacing generated by the rotating workpiece and the moving workpiece in the welding process are solved, the accurate control over the axial shortening amount of the friction welding is realized, and the axial dimensional precision of an axial friction welding workpiece and the quality of friction welding products are improved.

Description

technical field [0001] The invention relates to a technique for controlling the accuracy of friction welding axial deformation. Background technique [0002] Continuous drive friction welding and inertia friction welding, as two typical friction welding processes, have technical advantages such as high quality, high efficiency, greenness, energy saving, and are suitable for connecting heterogeneous materials. They are widely used in aerospace, automobiles, construction machinery, chemical, Power electronics and other engineering fields. In the friction welding process, the workpieces to be welded rub against each other under the action of axial welding pressure to generate welding heat, and the high-temperature plastic metal at the welding interface is extruded out of the welding interface under the action of welding pressure to form welding flash, making the axis of the welded workpiece The length is shortened, and the axial deformation is the axial shortening of the workp...
