Blade Disc Tool Magazine Layout Without Manipulator Tool Change
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blade disc machining centers require complex and costly manipulators for tool changing, which increase manufacturing costs, occupy space, and complicate the tool changing process, making it difficult to achieve high-precision and high-efficiency machining due to the angled swing head and non-coincident tool and spindle axes.
Innovation Solution
A blade disc machining center tool magazine and method utilizing a T1 linear axis, T2 axis rotation assembly, and A axis rotation assembly to facilitate tool changing without manipulators, enabling tool grabbing and releasing through single-axis cooperation of the Z, Y, and T1 axes, with the swing head axis parallel to the tool disc plane.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a manipulator is added for tool changing, then tool changing capability is achieved, but manufacturing cost increases and space is occupied
Solution Approach 1:
The patent extracts the tool changing function from the manipulator and integrates it into the machine tool's existing structure. The tool magazine is built into the machine tool body, and tool changing is achieved through coordinated movement of existing axes (T1 linear axis, T2 rotation assembly, A axis rotation assembly) rather than requiring a separate manipulator system.
Solution Approach 2:
The patent merges the tool changing mechanism with the machine tool's existing structural components. The T2 axis rotation assembly and A axis rotation assembly are integrated into the machine tool's coordinate system, and tool changing is achieved through the coordinated action of these existing assemblies rather than adding a separate manipulator system.
2Ease of operation
If a manipulator is used for tool changing, then tool changing can be achieved, but the installation position and posture requirements become complex
Solution Approach 1:
The patent makes the machine tool's existing axes (T1, T2, A axis) serve dual functions: both machining operations and tool changing operations. The T2 axis rotation assembly and A axis rotation assembly are designed to perform both cutting operations and tool magazine operations, eliminating the need for separate manipulator installation requirements.
3Ease of operation
If the tool axis, spindle axis, and manipulator grasping tool axis are made parallel or coincident, then tool changing cooperation with angled swing head is achieved, but tool changing control becomes complex and cumbersome
Solution Approach 1:
Instead of making the manipulator adapt to the angled swing head configuration, the patent inverts the approach by having the tool magazine and tool changing mechanism adapt to the machine tool's existing coordinate system. The T2 axis rotation assembly and A axis rotation assembly are configured to work with the angled swing head's natural orientation, reversing the conventional approach and simplifying control logic.

AI summary
A blade disc machining center tool magazine including a T2 axis rotation assembly; and an A axis rotation assembly, wherein the T2 axis rotation assembly can move along a T1 axis, and when an axis of a swing head is parallel to a plane where a tool disc is located, or is in the plane where the tool disc is located, the axis of the swing head is parallel to or coincides with a linear axis of the tool disc. A blade disc machining center tool changing method does not require the use of complex equipment such as manipulators. A tool changing process can be completely implemented by relying on the mutual cooperation of a Z axis, a Y axis and the T1 axis of a machine tool.
