Scroll Saw Abrasive Belt Clamp Holder for Cut-and-Grind Machining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scroll saws require multiple tools and processes for cutting and grinding, leading to increased machining time and labor intensity due to the need for separate tools and ineffective dust management, which poses health risks from sawdust dispersion.
Innovation Solution
An abrasive belt clamp holder for scroll saws that integrates a pin-free saw blade with an abrasive belt, featuring a driving mechanism and air draft assembly for dust collection, allowing for simultaneous cutting and grinding without tool changes and reducing labor intensity through efficient dust management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single-function clamp holder is used to clamp pin-free saw blades, then the saw blade can be securely held for cutting, but the workpiece must be removed and the clamp holder replaced with an abrasive belt for grinding, extending machining time
Solution Approach 1:
The clamp holder is designed to perform multiple functions: it can clamp pin-free saw blades for cutting operations and also hold abrasive belts for grinding operations. This is achieved by providing a clamp holder body with a clamp hole for receiving the saw blade, and simultaneously incorporating an abrasive belt groove and abrasive belt fixing components (fixing bolts, fixing plates) that allow the same clamp holder structure to secure abrasive belts. This multi-functional design eliminates the need to replace the clamp holder between cutting and grinding operations, thereby reducing machining time and improving productivity
2Ease of operation
If electric jigsaws are used for cutting and grinding, then the saw can be pulled up and down for cutting, but sawdust builds up on the sawpath requiring the operator to keep blowing to remove sawdust, increasing labor intensity and health risks
Solution Approach 1:
The patent converts the harmful sawdust byproduct into a manageable situation by incorporating a dust collection system. The system includes a dust collection port positioned to capture sawdust at its source, a dust collection bag connected to the port, and a dust removal pump that actively sucks sawdust through the collection port into the bag. This transforms the harmful dispersed sawdust into collected and contained material, eliminating the need for operators to manually blow away sawdust and reducing health risks while lowering labor intensity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables scroll saws to cut and grind workpieces more efficiently, reducing machining time and labor intensity by integrating abrasive belt functionality and effectively collecting sawdust, thereby improving the machining environment and reducing health risks.
Implementation Method 1
an air draft assembly is provided in the collecting housing and the driving mechanism drives the air draft assembly to work by means of the transmission mechanism
