Service HotlineAn elastic cylindrical pin assembling device, the assembling device includes an adapter handle, a punching needle, an elastic piece, a fixed sleeve and a telescopic sleeve, the adapter handle and the fixed sleeve are fixedly connected, and the punching needle is inserted into the adapter handle and fixed Inside the sleeve and its upper end is pressed against the adapter handle, the lower end of the punch needle is also inserted into the fixed sleeve and moves relative to the fixed sleeve in the up and down direction when the adapter handle pushes it to move up and down, the fixed sleeve A reset spring is also set between the punch and the punch, the lower end of the fixing sleeve has an insertion hole for the elastic cylinder pin, that is, a working cavity, and the lower end of the punch needle is also provided with a push fit for the upper end of the elastic cylinder pin. the positioning boss. When the elastic cylindrical pin assembling device is used, after assembling an elastic cylindrical pin, the elastic cylindrical pin needs to be re-installed into the fixed sleeve, which cannot realize continuous assembly and has low assembly efficiency.
With the continuous improvement of automation technology, human participation in the production process is gradually decreasing, especially in the processing of some small parts, the manual processing efficiency and accuracy are low. Whether the screws can be stably picked up and installed automatically is of great help to improve automated production.
With the rapid development of China's automobile industry, the requirements of body assembly process are constantly improving. Riveting has the characteristics of short process cycle, low noise and low energy consumption, and is widely used in automobile bodies. In the automobile industry, due to the complexity of the body sheet metal structure, there are many cavities, and the riveting tools in some positions will interfere with the structure. Many assembly points cannot use the traditional two-way loading riveting technology, so single-sided riveting is used instead. craft.
At present, the convex washers with traditional structures on the market have unreasonable designs and complex structures, and are inconvenient to install and disassemble. After long-term use, they are prone to fracture and deformation due to poor toughness, resulting in short service life and requiring regular downtime for maintenance, affecting assembly. The working efficiency and safety of its equipment are also poor in terms of wear resistance, corrosion resistance, and high temperature resistance. Regular replacement and maintenance also increase the economic cost of production. Therefore, the convex gasket of the existing structure can no longer meet the existing mechanical requirements. The high standard use requirements of assembly auxiliary parts are urgently needed to be solved at present.
There are many names for screws in the scope of application. Everyone may have different names. Some people call them screws, some people call them screws, some people call them standard parts, and some people call them fasteners. Although there are so many names, but the meaning is the same, they are all screws. A screw is a generic term for a fastener. The principle of the screw is to use the physical and mathematical principles of the oblique circular rotation of the object and the friction force to gradually tighten the tool of the utensil. Screws are indispensable in daily life and industrial production, so screws are also known as the rice of industry. The scope of application of screws includes: electronic products, mechanical products, digital products, electrical equipment, electromechanical mechanical products. Ships, vehicles, hydraulic engineering, and even chemical experiments also use screws. There are many types of screws, whether it is a very small screw for glasses or a large screw for large heavy electrical engineering. The accuracy of screws is usually 6g (class 2, the American standard IFI is 2A teeth), and the rough screws used in construction projects are 1g. Screws are widely used, so the screw market is large, resulting in more manufacturers producing screws. When buyers choose a professional screw manufacturer, they need to understand some professional basic knowledge of screws, such as screw classification standard specification and American screw specification table.
