Abstract

The invention discloses a riveting tool, and belongs to the technical field of machining. The riveting tool comprises an upper fixed plate and a lower fixed plate. Guide pillars are used for supporting between the upper fixed plate and the lower fixed plate. A supporting plate is further arranged between the upper fixed plate and the lower fixed plate. The supporting plate is supported on the lower fixed plate through a plurality of screws which are evenly distributed, and the screws can slide up and down in mounting holes of the lower fixed plate. A plurality of heading ends are arranged on the lower plane of the upper fixed plate. According to the technical scheme, stamping and heading forming can be performed on the ends of rivets through the heading end structure in the riveting process, so that the rivet heads and connecting pieces are compressed and fixed; stress is even, the phenomenon that the connecting pieces are staggered, and individual rivets are loosened without riveting can be avoided, the effect of improving riveting reliability is achieved, and connecting and fastening quality of riveted products is improved to a great extent.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and relates to an assembly connection auxiliary tool in mechanical processing, in particular to a riveting tool. Background technique [0002] Riveting is a traditional connection method. With the development of science and technology, although it has been replaced by welding and other technologies in some fields, it is not suitable for certain metal structures that are subject to severe shock and vibration, connections of heterosexual metals, and aluminum alloys. It still plays an irreplaceable role in metal connections with poor welding performance. For example, brake shoes for wind power and high-speed trains use riveting to connect the brake pads and steel backs. However, these riveting methods are connected by a plurality of rivets evenly distributed, how to ensure uniform fastening force of all rivets to parts has become a difficult problem in multi-rivet connection. For thi...
