Choice of fastening methods
1.Principles for selecting fastening methods
(1) The selected fastening method should comply with the characteristics and performance of the fastener to ensure the fastening performance of the fastener.
(2) The fastening method should be simple, reliable, and easy to inspect, and the required tools and accessories should be easily available.
(3) The repeatability of the fastening performance of the fastening method should meet the expected maintenance requirements.
2.Common types of fastening methods
(1) Fastening: Fastening is a commonly used fastening method and can be achieved using hand tools, machine tools or machining equipment.
(2) Plug and pull: This method uses the sealing effect of plug and pull to tighten the components under the design pressure.
(3) Welding: Welding is a fastening method that uses a heat source to fuse two or more components together.
(4) Riveting: Riveting refers to the use of rivets, screws, nuts or bolts to fasten components by hammering, pressing or mechanical tightening.
(5) Bonding: Bonding is a fastening method that uses adhesive to bond two or more components together.
Tools selection
1.Principles for selecting tools
(1) The tools selected should ensure the fastening quality and achieve the required torque value of the fastener.
(2) The material of the tool should be able to withstand the required force and increase the service life of the fastener.
(3) Tools should simplify operation, reduce labor intensity, and improve work efficiency.
2.Commonly used tools
(1) Wrench: A tool used to tighten, remove and adjust bolts, nuts and fasteners.
(2) Hammer: A tool used to tighten rivets, nuts, and bolts. It can be used to adjust the pressure of fasteners.
(3) Pliers: Used to remove, install and adjust nuts, bolts and fasteners. Many pliers have multiple interchangeable jaws to meet different usage requirements.
(4) Wrench: A tool used for welding, locking and adjusting fasteners. It can be used for rapid assembly of fasteners and adjusting bolt pressure.
(5) Tapping tools: used to tighten bolts, nuts, and fasteners, and can fine-tune and accurately tighten fasteners.
In recent years, fastening methods and tools have continued to emerge. Integrated nails and nail guns emerged as new fastening tools. With their easy operation, high safety, and strong stability, they quickly occupied the market and became the most popular fastening tools at present.
