Abstract

The invention discloses portable no-key-hole friction stir spot welding equipment with a self-holding function. The equipment mainly consists of a power motor, a transmission mechanism, a welding mechanism, a servo mechanism, a brake, a shell and an armrest frame. The transmission mechanism consists of a shaft gear pair and a main shaft, and is connected with the power motor through a sleeve coupling. The servo mechanism consists of a servo motor and a spiral transmission device; the transmission mechanism is associated with the servo mechanism through an angular contact ball bearing; and the tail end is connected with the welding mechanism through a thread. The equipment is high in flexibility and portability, has the self-holding function in the welding process to deal with the welding demands of various workpiece shapes and various welding positions, largely reduces the requirements on operator physical ability and operation technology, improves the equipment welding stability, and facilitates to improve the welding quality and the production efficiency.

Description

technical field [0001] The invention belongs to the field of spot welding connection technology, in particular to a portable keyhole-less friction stir spot welding equipment with a self-supporting function. Background technique [0002] With the increasingly severe energy and environmental problems, the lightweight of vehicles has become an urgent requirement in the manufacturing fields of automobiles and aerospace. Therefore, aluminum alloys and magnesium alloys, which are representative of lightweight materials, are widely used in the manufacturing industry. Resistance spot welding is a key connection technology in industrial manufacturing processes and also meets the requirements of lightweight manufacturing. However, the resistance spot welding of aluminum alloys, especially high-strength aluminum alloys, faces some difficulties: first, metallurgical defects such as pores and thermal cracks are prone to appear in the joints, which significantly reduces the quality of th...
