Guide mechanism of gun drill of vertical numerical control drilling machine

Abstract

The invention discloses a guide mechanism of a gun drill of a vertical numerical control drilling machine. The guide mechanism comprises a spindle frame, a guide sleeve assembly slidably connected with the spindle frame and a driving device used for driving the guide sleeve assembly to slide along the spindle frame. The driving device is fixedly connected to the spindle frame. The guide sleeve assembly comprises a sliding seat, a guide sleeve support fixedly connected to the bottom of the sliding seat and a metal guide sleeve fixed to the guide sleeve support. The side, close to the spindle frame, of the sliding seat is provided with at least two guide rails. At least two sliding blocks are arranged on each guide rail. The sliding blocks are fixedly connected with the spindle frame. The middle portion of the metal guide sleeve is provided with a through hole matched with the gun drill. The guide mechanism can conduct accurate guiding and positioning on the gun drill of the vertical numerical control drilling machine while the gun drill conducts deep hole drilling.

AI Technical Summary

Benefits of technology

This new design improves upon existing designs by adding guides onto the slide-seat assembly instead of just one single slot. These guards help prevent errors caused when attaching the tooling directly to the machine's main frames without affecting their overall performance. Additionally, these improvements allow the entire mechanism to have greater stiffness while still allowing accurate movement between different parts within the system. Overall, this technology enhances precision and durability in machining operations such as drills and wire bonders.

Problems solved by technology

This patents discusses two technical problem addressed during machining operations involving deep holes that require accurate or consistency drills due to their instability caused by movement over uneven surfaces such as rocks. Current techniques involve fixing the part afterward while still performing deep hole processes can result in imprecise results if there are any deviations from this initial set point.
