Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional pneumatic drill driving device is used, then feed operation can be applied in tool axis direction, but the device structure becomes complex
Solution Approach 1:
The invention extracts and separates the feed operation function from the rotation driving function. The cylinder mechanism is designed to independently provide feed force to the tool rotation driving device, while the rotation is provided by a separate motor. This separation allows feed control without requiring complex integrated mechanisms, thereby reducing overall device complexity while maintaining feed operation capability.
Solution Approach 2:
The cylinder mechanism serves multiple functions: it positions the tool rotation driving device in the tool axis direction, provides feed force during drilling, and can be integrated with the positioning mechanism. This multi-functionality reduces the need for separate dedicated components, simplifying the overall device structure while maintaining operational capabilities.
2Measurement precision
If complex hydraulic systems are used for feed control, then precise feed operation is achieved, but device structure becomes more complex
Solution Approach 1:
The invention replaces complex hydraulic systems with a simpler pneumatic cylinder mechanism. The cylinder uses pneumatic pressure to generate feed force and control tool advancement. This substitution maintains precise feed control capability while significantly reducing device complexity by eliminating hydraulic fluid systems, pumps, and associated control mechanisms.
Solution Approach 2:
The invention uses pneumatic principles through the cylinder mechanism to achieve controlled feed operation. Compressed air is used to drive the piston, which in turn moves the tool rotation driving device along the tool axis. This pneumatic approach provides smooth, controllable feed motion without the complexity of hydraulic systems, achieving precise feed control with a simpler structure.

AI summary
A tool feeding mechanism for a tool driving device includes a cylinder mechanism, a positioning mechanism, and a holding mechanism. The cylinder mechanism moves a tool rotation driving device to hold and rotate a tool, in a tool axis direction on an exterior of a cylinder tube using power of a piston. The positioning mechanism is connected to the cylinder tube side of the cylinder mechanism either directly or indirectly in order to position the cylinder mechanism relative to a workpiece. The holding mechanism holds the tool rotation driving device such that the power of the piston in the cylinder mechanism is transmitted to the tool rotation driving device.
