Force-temperature double-control magnetic suspension workbench for stirring friction welding and control method thereof

Abstract

The invention discloses a force-temperature double-control magnetic suspension workbench for stirring friction welding. The force-temperature double-control magnetic suspension workbench comprises a bottom support, an electromagnetic movable frame, a workbench and a stirring head. The bottom support is supported on a machine tool, the electromagnetic movable frame movably sleeves the bottom support, an electromagnet can attract the bottom support to generate suspension force to drive the electromagnetic movable frame to slide up and down relative to the bottom support so as to support the workbench, and the stirring head is arranged at the top of the workbench and can slide along a welding seam of a part to be welded. Magnetism generated by the electromagnet can attract the bottom support,suspension force is generated, the workbench is supported, mechanical friction, contact abrasion and lubrication are avoided, and the crawling problem in the mechanical transmission process is thoroughly eliminated. The invention further provides a control method of the force-temperature double-control magnetic suspension workbench for stirring friction welding.

Description

technical field [0001] The invention relates to the field of friction stir welding, in particular to a friction stir welding force-temperature dual-control magnetic levitation workbench and a control method for the friction stir welding force-temperature double-control magnetic levitation workbench. Background technique [0002] As a solid phase joining process, friction stir welding is widely used in the joining of aluminum alloys, magnesium alloys and other metals. Friction welding is a method of using the heat generated by the mutual movement and friction of the workpiece ends to make the ends reach a thermoplastic state, and then quickly upset to complete the welding. Friction welding can easily join the same or dissimilar materials, including metals, some metal matrix composites, ceramics and plastics. The friction welding method has been used in the manufacturing industry for more than 40 years. Due to its high productivity and good quality, it has been widely used in...

Problems solved by technology

The friction welding method has been used in the manufacturing industry for more than 40 years. Due to its high productivity and good quality, it has been widely used in engineering applications. However, the welding objects are mainly rotary parts. Although other forms of friction welding technology have emerged to overcome the The limitation of the geometry of the welded workpiece may increase productivity, but in the welding process, the heat generated by friction is not easy to control, and due to factors such as flash and thermal deformation of the material, the quality of the weld is not uniform during the welding process
