Service HotlineCombination bolts refer to a bolt with a spring washer and a flat washer, which are combined by rubbing teeth. Before the combination bolt is used, the bolt, the spring washer and the flat washer are generally combined by a specific machine. The combined production line mainly includes the processes of feeding, discharging, feeding, charging, screwing and tightening. The existing combined bolt production equipment mainly transmits the bolts to each process through the conveyor belt, and finally completes the combined assembly. The machines in each process are scattered and the space is occupied. The vibrating plate feeding generally puts the bolt head up, and its bolts, spring washers, etc. After the flat pad is assembled, the fixation is poor, and it is easy to fall off during the assembly process.
Nuts are parts that tightly connect mechanical equipment. Through the inner threads, nuts and bolts of the same specification can be connected together. For example, M4-P0.7 nuts can only be connected with M4-P0.7 series bolts (in the nut). Among them, M4 means the inner diameter of the nut is about 4mm, and 0.7 means that the distance between the two threads is 0.7mm); the same is true for American products, for example, a 1/4-20 nut can only be matched with a 1/4-20 screw ( A 1/4 finger nut has an inner diameter of about 0.25 inches, and 20 fingers have 20 teeth in each inch).
In response to the above situation, Yueluo uses various methods to fasten the locked nuts and bolts in actual operation, such as super glue, electric welding, secondary reinforcement by perforation, etc., but there is still no way to get it right Solve the phenomenon that the nut is loose and displaced.
The round nut is often used with the round nut with a stop washer. When assembling, insert the inner tongue of the washer into the groove on the shaft, and insert the outer tongue of the washer into the groove of the round nut, and the nut will be locked; loose. Often used as the axial fixation of rolling bearings. Round nut with thread size of M10×1～M200×3. The thread specification D=M16×1.5, the material is 45 steel, the groove or all heat treatment hardness HRC35～45, the marking of the surface oxidation round nut: nut GB/T 812-88 M16×1.5.
The anti-rotation T-bolt includes a screw rod and a head. An anti-rotation protrusion is designed at the connection between the head and the screw. The cross-section of the anti-rotation protrusion is a square corner with the screw radius as the side length. One anti-rotation protruding shoot can be designed, or two can be designed. In order to ensure the uniform force of the bolt, two are designed.
