Drilling and Splitting Device with Coaxial Tool Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional devices for drilling and splitting solid materials face challenges such as large maneuvering space requirements, high leverage forces, and inefficient handling due to the need for rotating working heads and lateral displacement of tools, which complicates the process and increases operational difficulties.
Innovation Solution
The device features a drilling axis that remains stationary relative to the carriage carrier, allowing the drill to be retracted and the splitting device to be moved coaxially into the borehole, minimizing dynamic leverage forces through linear movement and separate feed devices for drilling and splitting, with optional elastic elements and position centering to enhance stability and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the drill protrudes perpendicularly from the holding plate and the holding plate is rotated 180° to insert the splitting tool, then the drilling and splitting operations can be performed alternately, but a large maneuvering space is required during rotation which is not always available
Solution Approach 1:
The device is segmented into a drilling device and a splitting device that are spatially separated and can be independently positioned. The drilling device remains in its drilling position while the splitting device can be moved to the borehole location, eliminating the need for rotating the entire holding plate and reducing maneuvering space requirements.
Solution Approach 2:
The splitting device is moved from a rotational positioning mechanism to a linearly displaceable mechanism along the drilling axis. This dimensional change from rotational to linear movement allows the splitting tool to be inserted into the borehole without requiring large lateral maneuvering space, while still achieving alternating operations between drilling and splitting.
2Ease of operation
If the drill is several meters long and the plate is laterally displaced, then the drill can be retracted and the splitting tool can be positioned, but high leverage forces occur due to forces of inertia and moments of inertia
Solution Approach 1:
Instead of laterally displacing the entire plate with the long drill attached, the invention keeps the drilling device stationary and moves only the splitting device to the borehole. This inversion of the movement approach eliminates the high leverage forces that would act on a laterally displaced plate with a long drill, as the drill remains fixed and only the lighter splitting device is moved.
Solution Approach 2:
The splitting device is extracted from the lateral displacement mechanism and positioned independently at the borehole location. This allows the drill to remain stationary and fixed, eliminating the inertial and moment forces that would be generated by laterally moving a long drill, while still enabling the splitting operation to be performed.
3Adaptability or versatility
If the working head and drilling device are rotated to change from drilling to splitting, then tool functionality can be changed, but the working head and drilling device must be rotated which complicates handling
Solution Approach 1:
The device employs dynamic positioning where the splitting device can be independently moved to and from the borehole location as needed. This dynamic arrangement allows the system to switch between drilling and splitting modes by simply positioning the appropriate tool at the work location, rather than rotating the entire working head, thereby simplifying handling and improving operational flexibility.
