Mobile and modular drill apparatus, components thereof, and methods of use
An apparatus providing a platform for installing screws can include a cart with wheels, an assembly rail system mounted to the cart, and a screw assembly mounted to the assembly rail system. The screw assembly can include a screw feeding device, a screw guide tube, and a screwing device such as a drill that rotates a drive shaft that engages a screw received from the screw guide tube. The screw feeding device can include a screw rack that holds screws, and a magnetic grip that moves a screw from the screw rack to a screw feeding tube that is connected to the screw guide tube. The screw guide tube can include bristles for centering a screw received from the screw feeding tube. The apparatus can include a computer control system that operates the screwing device and the screw feeding device.
1. A screw feeding device, comprising:
a screw feeding tube;
a screw rack for holding a plurality of screws; and
a solenoid to release a single screw from the screw rack;
a magnetic grip that moves a single screw from the screw rack to the screw feeding tube.
2. The screw feeding device of claim 1 , wherein the screw feeding tube has a first opening dimensioned to receive the single screw,
wherein the first opening comprises a screw slot along the longitudinal axis of the screw feeding tube.
3. The screw feeding device of claim 1 , further comprising:
a screw guide bracket to support and guide the single screw towards the magnetic grip; and
an air piston to advance the single screw through the screw guide bracket.
4. The screw feeding device of claim 3 , further comprising:
a rotatable rod, wherein the magnetic grip is mounted on the rotatable rod; and
a screw feeding motor coupled to the rotatable rod.
5. The screw feeding device of claim 4 , wherein actuating the screw feeding motor rotates the rotatable rod until the single screw is passed through the first opening and dropped into the screw feeding tube.
6. The screw feeding device of claim 1 , comprising:
a magnetic grip that moves a single screw from the screw rack to the screw feeding tube.
7. The screw assembly of claim 6 , further comprising:
a screw guide tube having a side aperture connected to a second opening of the screw feeding tube of the screw feeding device, the second opening located near a bottom end of the screw feeding tube,
wherein the lower portion of the screw guide tube comprises a plurality of bristles for centering the received screw within the screw guide tube, each bristle of the plurality of bristles projecting from an interior surface of the screw guide tube inwardly towards the center of the screw guide tube, the plurality of bristles providing support to hold the received screw while the screwing device drives the received screw through the hole at the proximal end of the screw guide tube.
8. An apparatus, comprising:
a cart with wheels;
an assembly rail system mounted to the cart; and
a screw assembly, the screw assembly comprising:
a screw feeding device, the screw feeding device comprising:
a screw feeding tube;
a screw rack for holding a plurality of screws; and,
a solenoid to release a single screw from the screw rack.
9. The apparatus of claim 8 , wherein the assembly rail system is dimensioned to support a plurality of screw assemblies, each one of the screw assemblies comprising the screw assembly, the screw assemblies configured to be removably and slidably mounted to the assembly rail system, whereby a predetermined distance between each one of the screw assemblies is adjustable, and whereby the apparatus drills a set of screws into the workpiece.
10. The apparatus of claim 8 , wherein the wheels are motorized.
11. The apparatus of claim 8 , wherein the screw assembly further comprises a pneumatic drive that provides a force to drill the received screw into the workpiece.
12. The apparatus of claim 11 , furthering comprising:
a compressor that enables the force to move the pneumatic drive, wherein the compressor further enables an opposite force to return the draft shaft to a rest position.
13. The apparatus of claim 11 , wherein the screw assembly further comprises a plurality of limit stops, wherein a limit stop of plurality of limit stops disengages the screwing device or the pneumatic drive.
14. The apparatus of claim 11 , further comprising:
a computer control system that operates the screwing device, the screw feeding device, the pneumatic drive or a combination thereof.
15. The apparatus of claim 14 , wherein the computer control system comprises:
a memory that stores instructions; and
a processor that executes the stored instructions to perform operations, the operations comprising:
activating the screw feeding device to feed the single screw to the screw guide tube.
16. The apparatus of claim 15 , wherein the operation further comprise activating the screwing device to rotate the drive shaft.
17. The apparatus of claim 15 , wherein the operation further comprise activating the pneumatic drive to drill the received screw into the workpiece based on a distance from a prior screw insertion.
18. The apparatus of claim 15 , wherein the operations are based on user input via an operator control.
19. The apparatus of claim 8 , further comprising a visual indicator.
20. The apparatus of claim 8 , further comprising a foot pedal.
