In the process of locking screws for products with automatic screw locking machines, there are only three traditional screw supply mechanisms for automatic screw locking machines: 1. Magnet suction screw supply; 2. Vacuum suction screw; 5 Blow air to supply screws. The above three methods all require remote screw supply, resulting in slow screw supply speed, low efficiency, and high manufacturing costs. To this end, we propose an automatic locking screw machine that can directly supply screws.

A screw is a common threaded connection component mainly used to fix a part to the connection body. When it is necessary to connect, use a screw to pass through the hole on the connected part and screw the external thread on the screw into the connecting body to tighten it; When disconnecting the connection, unscrew the screws from the connection body to separate the connected parts from the connection body. The existing tools commonly used for screw disassembly are generally Adjustable spanner, open-end wrench, box wrench, socket wrench, Hex key, slotted screwdriver, cross screwdriver, etc., and one screw can only be disassembled with one or a class of tools; When the types of tools are not complete, it is difficult to complete the screw disassembly and assembly work, and the screw disassembly and assembly work is greatly limited by the tools.

Pins, also known as pins, have a simple structure and are easy to assemble and disassemble. They are widely used in various fixed connections. Pins are mainly used to fix the relative position between two parts, also used to connect parts, and can transmit a certain load. Currently, pins in the market are generally prone to loosening and falling off.

Special shaped screws are generally used in mining machinery, bridges, automobiles, automobiles, boiler steel structures, suspension towers, large-scale steel structures, large buildings, etc. However, the special-shaped screws used in the assembly of the automobile and electronic industries with previous structures are not easy to install and disassemble, and are easy to deform after long-term use. The high temperature, poor corrosion resistance and short life require regular inspection, which affects the use efficiency. Sleeper track fixing screws belong to the field of fixed connectors of Railway track. The fixed screws of the sleeper guide rail currently used have poor sealing and rust resistance due to their structural characteristics. They require rust prevention maintenance every year, wasting a lot of manpower and materials, and posing a threat to the safety of railway transportation. Guangdong Yueluo Hardware Industry Co., Ltd. provides sleeper guide rail fixing screws with simple structure, convenient processing, low rusting resistance, and excellent durability to address the shortcomings of existing sleeper guide rail fixing screws. Guangdong Yueluo Hardware Industry Co., Ltd. is composed of nuts, nuts, and screws. The hexagonal cylindrical nut and cylindrical threaded cover are integrated, and the screws are processed into nuts and fixed on the railway sleeper threaded rod. The thread length is less than the height of the nut. During installation, the rust proof oil pressure is first applied to the nut for fixation. After fixation, the nut of the sleeper guide rail fixing screw seals the sleeper screw, spring washer, and washer together to prevent external rainwater, acid, alkali, and oil from corroding the screw, maintaining a certain strength of the screw.

To sum up, a Rivet nut provided by Guangdong Screw includes a flange shaped nut body 1 and a folding adhesive layer 5. The folding adhesive layer 5 is coated on the outer wall surface of the bending part and the deformation part 3. After the Rivet nut is riveted, the folding adhesive layer 5 is filled in the connection between the nut body 1 and the sheet metal plate 6, which can enhance the connection strength of the nut and the sheet metal plate 6, and improve the torsional resistance of the Rivet nut, Prevent the Rivet nut from rotating with the bolt when the bolt is assembled with the Rivet nut; The evenly distributed groove can make the metal plate at the edge of the mounting hole of the sheet metal part 6 partially embedded into the groove due to deformation during riveting, improve the torsional resistance of the Rivet nut, increase the bonding area of the fold adhesive layer 5, and further strengthen the connection strength between the nut and the sheet metal part 6; Automotive edge folding adhesive can mix with the oil on the surface of the white body without affecting its oil surface bonding strength, and can withstand various process conditions during the production process of the body.
