Vacuum embedded bit for screw drivers
View Patent ↗An apparatus for driving fasteners includes a rotatable bit having a bit tip mateable with a fastener, a vacuum source, and a rotatable sleeve having an outlet in communication with the vacuum source. The bit may be press fit within the sleeve such that the bit and the sleeve are rotatable together. Aspects of a method of rotating a fastener with a apparatus for driving fasteners, the apparatus for driving fasteners having a rotatable bit having a bit tip, and a rotatable sleeve having an outlet, wherein the bit is press fit within the sleeve such that the bit and the sleeve are rotatable together, the method including providing a vacuum to the outlet of the sleeve, engaging the bit tip and the sleeve with the head of the screw with assistance from the vacuum, and rotating the bit, thereby rotating the sleeve and the fastener.
1. An apparatus for driving fasteners comprising:
a vacuum source;
a vacuum block having an inlet port;
a driver;
a rotatable bit having a first portion coupled with the driver and a second portion having a bit tip mateable with a fastener;
a rotatable sleeve having a first portion, wherein the first portion of the rotatable bit is press fit within the first portion of the rotatable sleeve; and
a vacuum channel formed between a second portion of the rotatable sleeve and the second portion of the rotatable bit, wherein the rotatable sleeve further comprises an opening in communication with the vacuum source and with the vacuum channel;
wherein the first portion of the rotatable sleeve is rotatably coupled with the vacuum block;
wherein the second portion of the rotatable sleeve defines an outlet in communication with the vacuum source through the vacuum channel, the opening and the inlet port providing a vacuum to engage the fastener to the outlet;
wherein the bit tip extends out of the outlet of the rotatable sleeve.
2. The apparatus of claim 1 , wherein the vacuum block has a vacuum input line in communication with the outlet of the rotatable sleeve and the vacuum source.
3. The apparatus of claim 2 , further comprising one or more bearings surrounding the rotatable sleeve, wherein the vacuum block is coupled to the rotatable sleeve via the one or more bearings.
4. The apparatus of claim 1 , wherein the vacuum channel extends from the opening to the outlet.
5. The apparatus of claim 1 , wherein the rotatable sleeve is operable with a fastener having a head diameter substantially equal to an outer diameter of the rotatable sleeve.
6. The apparatus of claim 5 , wherein the outer diameter of the rotatable sleeve is from about 2.0 mm to about 4.0 mm.
7. A method of rotating a fastener with an apparatus for driving fasteners, the apparatus comprising a rotatable bit having a bit tip, and a rotatable sleeve having an outlet, wherein the bit is press fit within the rotatable sleeve such that the bit and the rotatable sleeve are rotatable together, the method comprising:
providing a vacuum source, a vacuum block having an inlet port, and a driver, wherein the rotatable bit has a first portion and the rotatable sleeve has a first portion coupled with the driver, wherein the first portion of the rotatable bit is press fit within the first portion of the rotatable sleeve;
forming a vacuum channel between a second portion of the rotatable sleeve and a second portion of the rotatable bit, wherein the rotatable sleeve further comprises an opening in communication with the vacuum source and with the vacuum channel, wherein the first portion of the rotatable sleeve is rotatably coupled with the vacuum block and the second portion of the rotatable sleeve defines the outlet in communication with the vacuum;
providing a vacuum to the outlet of the rotatable sleeve through the vacuum channel, the opening and the inlet port;
engaging the bit tip and the outlet of the rotatable sleeve to a head of the fastener with assistance from the vacuum, wherein the bit tip extends out of the outlet of the sleeve; and
rotating the bit, thereby rotating the rotatable sleeve and the fastener.
8. The method of claim 7 , wherein the vacuum is provided to the outlet of the rotatable sleeve by the vacuum block through a vacuum input line.
9. The method of claim 8 , wherein the driver is coupled to the vacuum block.
10. The method of claim 8 , wherein the apparatus further comprises one or more bearings surrounding the rotatable sleeve, and wherein the vacuum block is coupled to the rotatable sleeve via the one or more bearings.
11. The method of claim 7 , wherein the channel extends from the opening to the outlet.
12. The method claim 7 , wherein an outer diameter of the rotatable sleeve is substantially equal to a diameter of a head of the fastener.
13. The method of claim 12 , where the outer diameter of the rotatable sleeve is from about 2.0 mm to about 4.0 mm.
