Problem
The oil supply tank in existing drilling devices is prone to damage during transportation and use, necessitating easy replacement and secure connection to the oil supply passage.
Innovation Solution
A drilling device design featuring a removably fixed oil supply tank positioned between the tool body and the fixing member, with a tubular slide unit allowing vertical displacement for easy attachment and secure fixation, and a pressurized air supply unit to prevent damage by aligning and connecting the oil and air supply lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the oil supply tank is disposed in a space between the electromagnetic fixing member and the cutting edge drive unit, then the tank is less likely to be damaged by collision, but the tank cannot be easily replaced and connected to the oil supply passage
Solution Approach 1:
The drilling device is divided into separable modules: the tool body can be detached from the column, and the oil supply tank is independently mounted on the tool body. This segmentation allows the tank to be positioned in a protected location while maintaining easy replaceability through modular assembly and disassembly.
Solution Approach 2:
The tool body is designed to be dynamically movable along the column, enabling it to shift position to accommodate the attachment and detachment of the oil supply tank. This dynamic positioning capability facilitates easy replacement while maintaining the tank's protected position during operation.
2Reliability
If the oil supply tank is made with lateral protuberances for connection, then the connection to oil supply passage is secured, but the tank becomes more susceptible to damage during transportation and use
Solution Approach 1:
The connection structures (protrusions and recesses) are integrated into the tank body in a nested manner, where connection elements are embedded within the tank structure rather than protruding outward. This nesting approach maintains secure connection capability while minimizing external protrusions that could cause damage during handling.
Solution Approach 2:
The connection features are merged with the tank body structure itself, combining the functional elements for secure attachment with the tank's structural design. This integration eliminates separate protruding components while maintaining reliable connection to the oil supply passage.
3Ease of operation
If the tool body is displaced upward to facilitate tank attachment, then the tank can be easily connected, but the tank may collide with surrounding objects during the movement process
Solution Approach 1:
The tool body is pre-positioned in an upper displaced state before tank attachment occurs. This preliminary positioning creates sufficient clearance and space for the tank to be safely attached without requiring movement during the connection process, thereby eliminating collision risks.
Solution Approach 2:
The column serves as an intermediary guide structure that enables controlled movement of the tool body. By providing a defined sliding path, the column mediates the movement process to prevent unintended collisions with surrounding objects while facilitating the necessary displacement for tank attachment.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy replacement and secure connection of the oil supply tank, reducing damage risk and avoiding issues like pump blockage and freezing, while ensuring continuous cutting oil supply to the tool.
Implementation Method 1
The pressurized air supply unit has a pressurized air supply passage for supplying pressurized air to the oil supply tank. The pressurized air outlet is directed downward toward the fixing member. The oil supply tank has a pressurized air inlet directed upward and communicated with the pressurized air outlet. The oil supply tank receives pressurized air from the pressurized air supply unit to pressurize the inside of the oil supply tank so that cutting oil is discharged from the cutting oil outlet
Implementation Method 2
a fixing member configured to be removably fixed to a workpiece by means of an electromagnet

AI summary
A drilling device having an oil supply tank disposed at a position where the oil supply tank is less likely to collide with surrounding objects. This device includes a fixing member (12) fixed to a workpiece, a column (14) extending upward from the fixing member, a tubular slide unit (16) that is slidable along the column, a tool body (18) disposed on the tubular slide unit, and an oil supply tank (20) provided between the tool body and the fixing member and removably fixed to the tubular slide unit. The tool body is provided with a cutting oil supply passage having a cutting oil inlet (109) disposed toward the fixing member, while the oil supply tank is provided with a cutting oil outlet disposed upward. The tool body is displaced upward on the column and the oil supply tank is moved close to the tool body from the lower side of the tool body, whereby the cutting oil outlet of the oil supply tank is connected to the cutting oil inlet of the tool body.
