Abstract
Description
- US Provisional Application No. 62/385,537 filed on Sep. 9, 2016
- Not Applicable
- Not Applicable
- The present invention relates, generally, to a high-speed micro drill attached to an articulating guide tube for work in constrained areas. Specifically, the present invention consists of an articulating guide tube, rubber tubing, a high-speed drill attachment and various drill bits and related attachments for grinding, blending, drilling, polishing and cutting materials in constricted spaces and areas otherwise inaccessible using conventional drills.
- Visual inspection, specifically Remote Visual inspection (RVI), as it relates to Nondestructive Testing (NDT), is a field long dominated by borescopes (of which video scopes and fiberscopes are a part) where distance, cumbersome angles and poor lighting preclude direct visual inspection of critical spaces for aberrations and imperfections that may affect the functionality of various mechanical devices. Moreover, while these areas may be accessible via direct inspection, the process is usually destructive, cost-prohibitive, time-inefficient (or a combination thereof) or in some other way wholly impractical.
- Clearly, while these mechanical devices tend to be on a larger scale in terms of both size and value, the functional aspects of dismantling machines and mechanisms for direct inspection on the size and order of aircraft engines, large steam, gas and wind turbines, electric generators and process piping (oil and gas and otherwise) is not only difficult and costly but otherwise untenable.
- Yet, inspection of the inner working components of such large machinery constitutes merely the diagnostic function of baseline inspections, outage planning, pre-commissioning, post-overhaul, unit troubleshooting and warranty inspections. Once discovered, minor and intermediate structural issues reach the same fate as major issues in that, once discovered, these defects must be made accessible through dismantling of the occluding portions of the machine in order to reach and repair the found imperfection(s). Just as visual inspection has the aforementioned physical and financial costs, so too does the restoration of integral parts through disassemblage and repair.
- The ability to correct found defects and aberrations that can readily lead to structural weaknesses and systems failures is a practical aspect of inspection (and the present invention) that has heretofore eluded inspection professionals. Although detection through various devices (i.e. rigid, flexible, and video-assisted borescopes) has long been a mainstay in the inspection field, correction of detected flaws and imperfections has not. The present invention, therefore seeks to remedy this deficiency.
- Thus, there is a long-felt but significant and un-met need in the art for an industrial high speed micro drill and method for use that aids inspection professionals in repairing damaged and flawed sections and areas of large machinery including engines, turbines, generators and piping, both investigational or remedial purposes, that is novel, practical and useful. The present invention satisfies this long-standing need in the art.
- The present invention provides a device (and method for use) that is intended to be an easy to use, as well as easily accessible and manipulated, device that facilitates the correction of detected flaws and materials weaknesses prior to a subsequent system failure or a cascading, multiple systems failures that could prove dangerous and costly, both temporally and financially. Advantages of the present invention include, but are not limited to, preservation of the integrity of the mechanical device being inspected, decreased time for minor and intermediate repairs, reduced cost for minor and intermediate repairs, and the ability to accomplish both in situ visual inspection and repair simultaneously.
- In a preferred embodiment, the present invention provides a device comprising a means to grind, blend, drill, polish and cut materials in areas that are constrained or otherwise spatially inaccessible. As Shown in
FIG. 1 , the industrial high speed micro drill that is thepresent invention 11 constitutes a means to accomplish required remedial repairing tasks which encompasses the parts including, but not limited to, (1) a high speeddrill head assembly 15, which is reversibly coupled to a combination (2) articulatingguide tube 19 and wholly encompassed (3)rubber tubing 21 that is made to run within the articulatingguide tube 19 and is structured and designed to provide pneumatic pressure to the high speeddrill head assembly 15 and (4) various drill bit attachments (not shown) that serve to allow for the present invention's functionality. Moreover,FIG. 1 further depicts one representation of anarticulation control unit 25 that is required for the manipulation and proper control and functioning of the present invention. Here, thearticulation control unit 25 is represented with 2 control knobs (27 and 29) which work singly and in combination to allow the drill bit to be operated in both X and Y planes (i.e. up, down and side to side) and to be discreetly placed in the desired area and position. And while thearticulation control unit 25 is a manually derived depiction, it is well observed, and within the spirit and the scope of the invention, to have an electronic controlling mechanism without detracting from the utility of the present invention. -
