Guiding device

The invention relates to a guiding device, in particular to a screw guiding device for an automatic screw machine.

In the production process, fasteners such as screws are often used to complete the assembly of equipment, parts, etc. In order to improve the assembly efficiency, an automatic screw machine has recently been used instead of the manual clamping screw. The automatic screw machine generally has a screw guiding device, which can prevent the screw from falling during the assembly process on the one hand, and can adjust the angle of the screw to make the axis coincide with the axis of the screw bit, so that the screw machine is more accurate. The ground is screwed into the workpiece.

A screw guiding device for an automatic screw machine comprises a sleeve, two claw blocks, two springs and a guiding cylinder. The sleeve is connected to the power unit of the automatic screw machine for the screw drill to pass. After the two claw pieces are fastened, the lower end forms a circular through hole, and the upper ends of the two claw pieces are respectively elastically connected to the sleeve through a spring, and after the two claw pieces are connected with the sleeve, the circular ends formed by the lower ends of the two claw pieces are formed. The bore is in communication with the central bore of the sleeve and is coaxial. The guide cylinder is connected to the sleeve from the side wall of the sleeve and is disposed obliquely with respect to the sleeve. The screw can be placed from the guide barrel and automatically fall from the central hole of the sleeve into the circular through hole of the two claw block. At this point, the drill bit can be inserted into the circular through hole of the two claw block from the sleeve and contact with the screw therein. When the drill bit continues to move downward, the upper end of the two claw block can be urged to compress the spring, thereby making the two claw block The lower end is opened to screw the screw into the workpiece.

The screw guiding device is mainly arranged and conveyed by the guiding cylinder, and is suitable for the screw whose screw length is much larger than the diameter of the screw head. If the diameter of the screw head and the length of the screw are small or roughly equal, the screw is easily turned over in the guide cylinder, and the accurate alignment of the screw cannot be achieved.

In view of the above, it is necessary to provide a guiding device that prevents the screw from turning over.
