Ordinary snap-type retaining rings have ears on their structure, which cause interference with the inner parts. If the ears are not provided, it is very troublesome to disassemble. For the very demanding aerospace field, ordinary snap rings cannot meet their requirements.
As we all know, bolt and nut kits are commonly used fastening parts, but when ordinary bolt fasteners are used in a large number of parts, because the nuts and bolts are engaged by threads, manual or machine tightening is required, and during installation, It is easy to slip, and the bolts need to be operated in both directions, and a pair of bolts and nuts cannot be installed quickly, which reduces the installation efficiency.
The automatic screw-removing device includes a manipulator and a screw-removing mechanism arranged on the manipulator, and the electric batch can drive the bit to rotate to remove the screws. Therefore, the above-mentioned automatic screw removal device can automatically remove the screws, which improves the removal efficiency and reduces the production cost. At the same time, the above-mentioned automatic screw removal device determines the coordinates of the screw through the visual recognition unit, which improves the degree of screw positioning, thereby improving the yield of the screw removal. The above-mentioned screw removal method can realize the automatic removal of the screw, and adsorb the screw through the bit head and drive the screw away from the workpiece.
Riveting nut tool is a special installation tool for riveting nut, including pneumatic riveting nut and electric riveting nut. Pneumatic riveting nut tool has the advantages of fast speed and large pulling force, but it is difficult to rotate into and unscrew the riveted nut. The rotating blade of the moving motor is frequently used or in a slightly dusty working environment, it will suddenly get stuck and not work, there is a great hidden danger of motor crash, and the torque of the air motor is small due to the limitation of the volume, although the riveting pulling force can be done to larger defects, but the volume also increases.
