Solution Overview
Problem
Conventional CNC dual-spindle machining centers face issues with large size, high installation costs, and excessive inertia weight due to the need for multiple servo driver units and a single spindle head slide seat that integrates both spindles, affecting precision and acceleration.
Innovation Solution
A CNC dual-spindle transmission device with a linear rail assembly, two independently mounted slide seats, and separate power units for each spindle, allowing for minimal linear rail usage and independent movement, reducing machine size and weight distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If two servo driver units are used to drive two spindles independently, then machining precision and acceleration are improved, but device complexity and installation cost increase
Solution Approach 1:
The patent divides the spindle drive system into two independent parts: a first spindle drive mechanism with its own servo motor and transmission components, and a second spindle drive mechanism with its own servo motor and transmission components. Each spindle is independently driven, allowing separate control and optimization of machining precision for each spindle while maintaining manageable complexity through modular design.
2Device complexity
If a single spindle head slide seat integrates both spindles, then device complexity is reduced, but inertia weight increases affecting precision and acceleration
Solution Approach 1:
The patent separates the spindles into different slide seats: the first spindle is mounted on a first slide seat, and the second spindle is mounted on a second slide seat. This segmentation distributes the weight across separate moving components, reducing the inertia weight of each individual slide seat compared to a single integrated seat carrying both spindles, thereby improving acceleration and precision.
3Ease of operation
If two servo driver units with four linear rails are installed, then independent spindle control is achieved, but machine size and material cost increase
Solution Approach 1:
The patent arranges the first and second slide seats and their associated linear rails in a spatial configuration that optimizes space utilization. By positioning the slide seats and rails in specific dimensional arrangements, the system achieves independent spindle control while minimizing the overall footprint and occupied area of the machine structure.
