Multi-Drill Driving Assembly for Synchronous Hole Drilling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drilling machines can only perform a single drilling operation at a time, limiting production efficiency and increasing costs due to the inability to meet the requirements of improved production efficiency and reduced production costs in modern production lines.
Innovation Solution
A multi-axis drilling device with a multi-layer base structure and a driving assembly that allows multiple drills to be actuated synchronously, featuring a transmission shaft, bearing base, and gear system to rotate and position multiple drills simultaneously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single drill is used in a conventional drilling machine, then the device complexity is low, but the productivity is low because only a single hole can be formed under a single operation
Solution Approach 1:
Multiple drills are combined into a single drill set that operates together under one base structure. The drill set includes multiple drill bodies arranged in specific positions, all driven by a common driving assembly, merging multiple drilling functions into one integrated unit that can drill multiple holes simultaneously
Solution Approach 2:
The base structure serves multiple functions: it provides structural support, houses the driving assembly, contains cooling channels for temperature control, and positions multiple drills. The driving assembly universally drives all drills in the set through a shared transmission mechanism, reducing the need for separate driving devices for each drill
2Productivity
If multiple drills are used to increase productivity, then the production efficiency is improved, but the number of driving devices increases leading to higher costs
Solution Approach 1:
Multiple drilling functions are merged into a single driving assembly that controls all drills through a shared transmission system. The driving assembly includes a motor, transmission shaft, and gear mechanism that distributes power to all drills in the set, eliminating the need for multiple independent driving devices
Solution Approach 2:
The driving assembly performs multiple functions: it generates rotational power, transmits it through the transmission shaft, distributes it via gears to multiple drills, and maintains synchronized rotation of all drills. This universal driving mechanism replaces what would traditionally require multiple separate motors and control systems
