Fastener Driver Pin-Rack Lubrication for Reduced Wear
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fastener driving machines lack a mechanism for lubricating pins and racks, leading to wear and tear, requiring frequent manual lubrication which is complex and inefficient.
Innovation Solution
Incorporation of a lubricant feeding mechanism that impregnates and feeds lubricant to the pins and racks, ensuring continuous lubrication and reducing abrasion over time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual lubrication is performed frequently to reduce wear of pins and racks, then the reliability is improved, but the ease of operation deteriorates due to complex maintenance procedures
Solution Approach 1:
The lubricant feeding mechanism enables the pins and racks to be lubricated automatically during operation without requiring manual intervention. The mechanism feeds lubricant to the engaging portions of the pins and racks that repeatedly engage with each other, allowing the system to maintain itself and eliminate complex maintenance procedures while ensuring continuous lubrication for reduced wear.
2Ease of operation
If a lubricant feeding mechanism is incorporated to automate lubrication, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The lubricant feeding mechanism is integrated into the existing pin and rack engagement system. The mechanism combines the lubrication function with the mechanical engagement structure, where the lubricant is fed to the engaging portions of the pins and racks that repeatedly engage with each other. This merging approach adds the lubrication function without creating a completely separate complex subsystem.

Function Achieved in This Case
The solution enhances maintainability and product lifetime by maintaining lubrication of pins and racks over a long period, reducing the need for frequent manual lubrication and minimizing wear, thus improving the machine's operational efficiency and longevity.
Implementation Method 1
a lubricant feeding mechanism configured to feed lubricant to the hitting member and the engaging member

AI summary
A fastener driving machine provided with a mechanism to lubricate pins or racks is realized. A fastener driving machine includes a driver blade, pins, and a lubricant feeding mechanism. The driver blade can reciprocate in a first direction and a second direction opposite to each other, and hits a fastener when the driver blade moves in the first direction. The pins respectively engage with racks provided on the driver blade to move the driver blade in the second direction. The lubricant feeding mechanism supplies lubricant to the racks and the pins.
