Cutting Tool Cartridge Adjustment Plate Recess Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cutting tools with cartridge adjustment mechanisms face limitations in adjustment range, manufacturing cost, and stability during machining due to complex tapered shims and thin plate displacement issues.
Innovation Solution
A cutting tool design featuring a cartridge mounting part with a recessed area for an adjustment plate, allowing for larger adjustment range and reduced manufacturing costs, with a flat surface for radial rake definition and through holes for secure fastening, ensuring stable cartridge positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a tapered shim is used to adjust the cartridge position, then fine adjustment can be achieved, but the adjustment range is limited and requires operating the adjustment bolt many times for large adjustments
Solution Approach 1:
The adjustment mechanism is segmented into multiple thin plates (adjustment plates) with different thicknesses. Instead of using a single tapered shim that requires repeated small adjustments, the invention divides the adjustment range into discrete segments represented by different plate thicknesses, allowing operators to quickly achieve both fine and coarse adjustments by selecting and installing the appropriate plate.
2Ease of operation
If a tapered shim with complex shape and screw hole machining is used, then cartridge position adjustment is enabled, but manufacturing cost increases
Solution Approach 1:
The adjustment function is extracted from the tool body structure. Instead of machining complex screw holes and tapered shims into the tool body, the invention uses separate, simple adjustment plates that can be independently manufactured and installed. This extraction simplifies the tool body manufacturing while maintaining full adjustment functionality.
Solution Approach 2:
The adjustment plates are designed as simple, inexpensive components that can be easily manufactured and replaced. Rather than investing in complex, expensive tool body modifications, the invention uses simple plates that serve the adjustment purpose effectively and can be replaced if needed without affecting the tool body.
3Measurement precision
If multiple thin plates are sandwiched between the cartridge and body for position adjustment, then fine adjustment can be realized, but the thin plates may become displaced or dislodged during machining
Solution Approach 1:
The adjustment plates are nested within a dedicated recessed part of the cartridge mounting structure. This nesting provides mechanical containment and support for the thin plates during machining operations, preventing them from becoming displaced or dislodged while maintaining the precision adjustment capability.
