Pressing rivet stud surface polishing device

Abstract

The invention relates to the technical field of mechanical parts, and discloses a pressing rivet stud surface polishing device. The pressing rivet stud surface polishing device comprises a working table and a stud main body. A first vertical column and a second vertical column are fixedly connected with the two sides of the top of the working table correspondingly, a first motor is fixedly connected with the position, on one side of the second vertical column, of the top of the working table, and an output shaft of the first motor is fixedly connected with a threaded rod through a coupler; anda first bearing is fixedly connected with one side of the second vertical column, a second bearing is fixedly connected with one side of the first vertical column, and one end of the threaded rod penetrates through the first bearing and is fixedly connected to the axis of the second bearing in an inserted mode. According to the pressing rivet stud surface polishing device, the threaded rod can conduct positive and negative rotation through arrangement of automatic positive and negative rotation of the first motor, finally a polishing machine is driven to move to polish the stud main body through a threaded pipe, so that the problems that a polishing error is prone to being generated, and the polishing efficiency is reduced when polishing is conducted manually are effectively solved, and using is convenient for people.

Description

technical field [0001] The invention relates to the technical field of mechanical parts, in particular to a surface grinding device for a pressure riveting stud. Background technique [0002] Riveting studs, also known as rivet studs or studs, are a kind of fasteners used in sheet metal, thin plates, chassis, and cabinets. Riveting studs have a hexagonal shape at one end and a cylindrical shape at the other end. There is an undercut in the middle of the side and the cylinder, and its inner shape is an internal thread. Press the hexagonal head into the preset hole of the thin plate through a press (the diameter of the preset hole is generally slightly larger than the outer diameter of the riveting stud cylinder) The periphery of the hole is plastically deformed, and the deformed part is squeezed into the relief groove of the rivet stud, so that the rivet stud is riveted on the thin plate, thereby forming an effectively fixed internal thread on the thin plate.
