Wood Component Machining with Single Actuator Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machines for machining wood or similar component parts, such as door and window frames, are complex and expensive due to the need for multiple actuating devices for each clamp.
Innovation Solution
A machining method utilizing a U-shaped bed with manual or actuated sliding cross members and a bridge-mounted machining head, where clamps are operated by a single actuating cylinder, eliminating the need for individual actuating devices for each clamp, and incorporating a feed device with belt conveyors and a grip-and-carry assembly for efficient part transfer and machining.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple actuating devices are used for each clamp to enable independent operation, then the clamping and machining operation is more flexible and reliable, but the device complexity and cost increase significantly
Solution Approach 1:
The patent merges multiple actuating devices into a single actuating device that controls multiple clamps simultaneously. The actuating device includes a single actuator that moves a carriage along the bridge, and the carriage carries multiple clamps that are actuated in unison. This combining approach reduces the number of actuators from multiple to one, simplifying the machine structure while maintaining the ability to clamp and machine multiple workpieces simultaneously, thus resolving the contradiction between reliability and device complexity.
2Ease of operation
If individual actuating devices are provided for each clamp to enable independent movement, then the machining flexibility and precision are improved, but the manufacturing cost and device complexity increase
Solution Approach 1:
The patent combines multiple individually actuated clamps into a single actuated carriage assembly. The carriage is mounted on the bridge and carries multiple clamps that can be positioned independently along the bridge length. A single actuator moves the entire carriage assembly, reducing the number of actuators needed while maintaining the flexibility to machine multiple workpieces at different positions simultaneously. This approach lowers manufacturing costs while preserving operational flexibility.
3Productivity
If multiple clamps with individual actuating devices are used to machine both sides of component parts, then the productivity and machining efficiency are enhanced, but the device complexity and expense increase
Solution Approach 1:
The patent merges multiple clamps into a single carriage assembly that is actuated by one actuator. The carriage can carry multiple clamps at different positions along the bridge, allowing simultaneous clamping and machining of multiple workpieces. The single actuator moves the entire carriage assembly, enabling coordinated operation of all clamps. This merging strategy maintains high productivity by processing multiple parts simultaneously while reducing actuating system complexity from multiple independent actuators to a single actuator controlling a multi-clamp carriage.
