With the development of the economy, automobiles have become an indispensable means of transportation in people's lives, and the production, sales and after-sales services of automobiles have also developed rapidly. Automobile wheels and steel rings are an important part of auto parts and are also related to The use of the car is safe. The connection between the car wheel and the steel ring is realized by bolts, so the bolts and nuts need to have good fixation.
shaft card assembling device, comprising two struts, the same fixing plate is welded on the side of the two struts that are close to each other, the top of the fixing plate is symmetrically fixed with a motor, and the output shafts of the two motors are welded with * a bevel gear;
All-aluminum blind rivet The body of the rivet is also made of high-quality aluminum wire, which is beautiful and durable after riveting and will never rust: Compared with ordinary blind rivets, rivets have lower riveting strength and are suitable for connectors with relatively soft materials. . Split Stainless Steel Rivet: This rivet is a high-tension, corrosion-resistant choice. Round head rivets are mainly used in riveting occasions subject to large lateral loads, and are the most widely used. Flat cone head rivets are often used in riveting occasions with strong corrosion such as ship hulls, boiler water tanks, etc.
M4 grounding screw used to fix the grounding wire on household appliances and other equipment, the stud is cylindrical, and the thread is perpendicular to the end (section) surface. However, the screw holes on the equipment all have tapping guide grooves for sinking and guiding due to the manufacturing process requirements. When fixing the ground wire, if the screw is not positioned accurately (the screw is inclined), the screw is pressed down hard, which is easy to cause the screw and the screw. The screw hole bites the teeth, and after biting the teeth, it is easy to cause the screw to loosen or fall off, posing a safety hazard.
The spring washer can prevent loosening and increase the pre-tightening force, while the flat washer does not have this function. It can be used to increase the tightening contact area, prevent the friction between the bolt and the workpiece, and protect the surface of the connector to prevent bolts. The surface of the workpiece is scratched when the nut is tightened. However, for some important connections, such as places that rely mainly on compression to generate frictional force to transmit power, spring pads cannot be used, and the rigidity of the connection is reduced, which is prone to accidents. Spring washers can be omitted. When the strength of the connected parts is low, use flat washers or flange bolts to increase the contact area. When there is vibration, pulse, and the temperature of the medium fluctuates greatly, spring washers must be used.
