Production of cross recessed round head three combination screw three in one screw round head combination screw 3/4

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.

1. For the lock ring of the anti-dropping nut, snap the ring into the lock, tighten the lock claw, and the lock claw is fastened into the thread. The lock claw does not have thread characteristics, and it is difficult for the nut to be threaded during the vibration process of the machine. If it fails, the locking claw acts as a tightening nut, but it does not have the problem of loosening itself like the locking nut.

Standardized mechanical parts for fastening connections. Standard fasteners mainly include bolts, studs, screws, set screws, nuts, washers and rivets. There are many structural types of bolts, and most of the heads are hexagonal. For bolts subjected to shock, vibration or variable load, in order to increase flexibility, the polished rod part is made into thin sections or hollows. The seat end of the stud is screwed into the threaded hole of the connected piece, and the nut used at the nut end is similar to the bolt nut. The structure of the screw is basically the same as that of the bolt, but the shape of the head is various to adapt to different assembly spaces, tightening degrees and connection appearances. Set screws have different head and tip shapes to accommodate different levels of tightening. Nuts are also available in a variety of styles, with hexagons being the most widely used.

The retaining ring is an industrial accessory that can function as support, buffering, braking, height adjustment and angle adjustment. The inner diameter of the retaining ring for the shaft is slightly smaller than the diameter of the assembly shaft. When the retaining ring for the hole is selected, the outer diameter of the retaining ring is slightly larger than the diameter of the assembly circular hole. The retaining ring mainly plays the role of axial fixation. The surface plus the retaining ring is fixed with a high degree of centering.
