Cutting Tool Insert Pocket With Tapered Groove for Easy Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting tools face difficulties in mounting and removing cutting inserts due to reduced tool diameter for small-diameter hole machining, making operations cumbersome and prone to insert dropping.
Innovation Solution
A body and cutting tool design featuring an insert pocket with a lower jaw part, upper jaw part, and a housing groove part, allowing resilient sandwiching of the cutting insert, and a screw hole positioned to avoid overlap with the upper jaw part, with a tilted central axis for enhanced thread count and stable fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the tool diameter is reduced for small-diameter hole machining, then the cutting tool can perform hole machining for smaller holes, but the mounting and removal operations of the cutting insert become difficult and the insert may drop during operations
Solution Approach 1:
The housing groove part is designed with a tapered configuration where the groove width on the leading end side is narrower than the groove width on the rear end side. This allows the cutting insert to be automatically held and positioned within the insert pocket without requiring manual grasping, enabling the structure to serve itself during mounting and removal operations
Solution Approach 2:
The solution transitions from a two-dimensional planar mounting surface to a three-dimensional tapered housing groove structure. The tapered configuration adds a dimensional aspect that enables automatic insertion and holding of the cutting insert, eliminating the need for hand grasping even in reduced-diameter tools
2Reliability
If the cutting insert is held with one hand and screwed with the other hand during mounting, then the insert can be securely fastened, but the operation becomes cumbersome and difficult when tool diameter is reduced
Solution Approach 1:
The tapered housing groove part enables the cutting insert to be automatically guided and held in position during mounting, eliminating the need for manual grasping. The structure itself performs the holding function that would otherwise require manual intervention
Solution Approach 2:
The insert pocket is segmented into distinct functional parts: the lower jaw part with screw hole, the upper jaw part, and the tapered housing groove part between them. This segmentation allows each part to perform its specific function independently, with the housing groove part handling positioning and holding while the screw provides fastening

AI summary
The present disclosure provides a body comprising an insert pocket into which a cutting insert is mounted, the insert pocket including: a lower jaw part having a screw hole; an upper jaw part that is arranged apart from the lower jaw part; and a housing groove part into which the cutting insert is inserted, the housing groove part being formed between the lower jaw part and the upper jaw part, wherein the housing groove part is formed such that a groove width on a leading end side is narrower than a groove width on a rear end side
