The commonly used tools for fixing screws on the surface of the workpiece are electric screwdrivers and manual screwdrivers. Both of these screwdrivers manually attach the screws to the bits of the electric screwdriver or manual screwdriver, and then fix the screws on the surface of the workpiece. The screwdriver is inefficient in fixing the screw, and cannot accurately locate the screw fixing point.
rivet is a nail-shaped object used to join two parts or components with a through hole and a cap on one end. In riveting, the riveted parts are connected by their own deformation or interference. There are many types of rivets, and they are informal, commonly used are R-type rivets, fan rivets, blind rivets, blind rivets, tree rivets, semi-circular head, flat head, semi-hollow rivets, solid rivets, countersunk head rivets, blind rivets, hollow rivets Rivets, these usually use their own deformation to connect the riveted parts. Generally less than 8 mm with cold riveting, larger than this size with hot riveting. But there are exceptions. For example, the nameplate on some locks is riveted by the interference between the rivet and the lock body hole.
The traveling plate can be driven by the traveling cylinder to move from the lower end of the circlip sleeve rod to the lower ends of the two probes of the circlip tightening mechanism; after the two probes tighten the circlip, the traveling plate can be moved in the traveling cylinder. The tightening mechanism moves down under the drive of the lifting cylinder, the probe installs the tightened circlip in the workpiece, and then retracts the probe upward.
One of the steps in the screw production and processing process is to slot the screw head to facilitate the use of a screwdriver when tightening or loosening the screw. Generally, companies use manual sorting, and then use the cutting knife to slot the front end screws through the track, which is inefficient, and because the screws are not fixed, the cutting knife may easily fly out or break the blade during cutting. It is a safety problem, and after cutting, the screw head has rough workmanship and burrs, which is easy to hurt the hand.
