Cutting Tool Holding Mechanism Vertical Locking Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting tool holding mechanisms for road milling machines are complex in design, have lower mechanical strength, and require time-consuming and costly tool changes due to parallel reaction forces and intricate assembly requirements.
Innovation Solution
A cutting tool holding mechanism featuring a base with abutting and receiving bores, a handle with positioning surfaces, and a locking assembly with a packing ring, locking screw, and guiding bolt, allowing for easy assembly, increased mechanical strength, and efficient tool changes by aligning the locking assembly's central axis with the vertical direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the cutting tool holding mechanism is made by several components (base, clamping portion, handle), then the assembly can be coordinated to fit together, but the mechanical strength is lower
Solution Approach 1:
The patent merges the base and clamping portion into a single integrated component. The clamping portion is formed as an extension of the base, eliminating the need for separate assembly of these two parts. This integration significantly enhances the mechanical strength and structural integrity of the cutting tool holding mechanism while simplifying the overall assembly process.
2Force
If screws are inserted into the cutting tool holding mechanism along the horizontal direction, then the clamping force is sufficient, but the separating operation is affected by other cutting tool holding mechanisms
Solution Approach 1:
The patent inverts the traditional screw insertion direction from horizontal to vertical. The screw is inserted vertically from the top of the base, perpendicular to the handling surface, rather than horizontally as in conventional designs. This inversion allows the screw to pass through the base and secure the handling without being interfered with by adjacent cutting tool holding mechanisms, thereby facilitating easier separation and tool changes.
3Force
If the connecting surface between the base and clamping portion is parallel to the horizontal direction, then the supporting force is sufficient, but the design becomes complex and manufacturing cost increases
Solution Approach 1:
The patent merges the base and clamping portion into a single monolithic component, eliminating the connecting surface between them. The clamping portion is formed as an integral extension of the base, which not only simplifies the design and reduces manufacturing complexity but also enhances the structural strength by eliminating potential weak points at the joint interface.
4Reliability
If the cutting tool holding mechanism is firmly secured, then the cutting tool is securely held, but the assembly and separation time increases
Solution Approach 1:
The patent segments the cutting tool holding mechanism into distinct functional components: the base, the handling (cutting tool), and the locking assembly. This segmentation allows for independent assembly and disassembly of these components through a simple vertical screw operation, maintaining secure holding during operation while enabling rapid tool changes by loosening and removing the screw.

AI summary
A cutting tool holding mechanism includes a base, a handle and a locking assembly. The base includes an abutting portion, a receiving bore, at least one limiting bore and at least one limiting hole. The limiting hole is disposed at the base and communicated with the limiting bore. The handle abutted against the base includes a sleeved portion and a plurality of positioning surfaces. The locking assembly includes a packing ring, a locking screw, a locking member and a guiding bolt. The locking member received inside the limiting bore includes a screwed hole and a guiding groove. The guiding groove disposed at one side of the locking member and is aligned with the limiting hole when the locking member is disposed inside the limiting bore. The guiding bolt is disposed in the limiting hole and is abutted against the guiding groove to inhibit the locking member from rotating.
