Screw head table

Some electronic products need to install some plastic parts or protective sleeves for components on the PCB, which need to be fixed by screws. The function of the fixture is to locate the PCB and the required installation parts, and increase the work efficiency. The existing screw fixture is inconvenient According to the needs of the site, the positioning station of the screw can be changed, the accurate positioning of the screw is difficult and the clamping effect of the workpiece is poor. A screw jig is proposed.

In actual use, the rivet rod body 3-2 is passed through the riveting plate 6 and the riveting plate 7, and the rivet dome head 3-1 is placed in the mold cavity 1-1, and the cover mold 2 is driven by the riveting machine to impact the rivet rod body 3-2. Because the center of the cover mold 2 is provided with a cavity 2-1 that matches the shape of the rivet dome 3-3, the end of the rivet rod 3-2 will form the rivet dome 3-3. However, due to the rivet When the riveting machine is impacted and vibrated, a large amount of oxide slag 4 will be generated, and the oxide slag 4 will slide down the surface of the cavity 1-1 to the bottom of the cavity 1-1 and accumulate. At this time, the temperature of the rivet is very high and the plasticity is very good. The hardness is extremely low and it is easy to form. Therefore, the accumulated oxide slag 4 squeezes the surface of the rivet dome 3-1 and the bottom surface of the cavity 1-1 to form pits, and causes wear on the bottom surface of the cavity, not only It affects the riveting quality, riveting strength and appearance quality of the rivet, and also affects the quality of the rivet die, resulting in economic losses.

Gaskets are mechanical components used for cooperation between two objects, which play a role in preventing pressure, corrosion and leakage of pipes from natural thermal expansion and contraction between two objects. By using the gasket in conjunction with the bolt and nut, the gasket can increase the contact area between the bolt and nut and the metal parts, and play the role of buffering and shock absorption to prevent the thread from loosening.
