Pressing rivet stud surface polishing device

Abstract

The invention relates to the technical field of mechanical parts, and discloses a riveting stud surface grinding device, which includes a workbench and a stud main body. The two sides of the top of the workbench are respectively fixedly connected with a first column and a second column. The top of the workbench is fixedly connected with a first motor on one side of the second column, the output shaft of the first motor is fixedly connected with a threaded rod through a coupling, and one side of the second column is fixedly connected with a first bearing A second bearing is fixedly connected to one side of the first column, and one end of the threaded rod passes through the first bearing and is fixedly inserted into the axis of the second bearing. The surface grinding device for pressure riveting studs can make the threaded rods rotate forwards and reverses through the setting of automatic forward and reverse rotation of the first motor, and finally the threaded pipe drives the grinding machine to move to grind the main body of the studs, thus effectively solving the problem of artificial Grinding is easy to produce the problems of grinding errors and reduced grinding efficiency, which is convenient for people to use.

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.
