Compression Line Spring Grinding with Adjustable Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional grinding apparatuses for compression line springs require precise alignment and setting of support blocks to stably fix the springs, making them difficult to manufacture, use, and maintain.
Innovation Solution
The apparatus and method involve adjustable chain conveyors with V-shaped support blocks that can accommodate misalignment, allowing for stable fixation of compression line springs without precise alignment, using adjustable distances and heights to ensure proper seating and grinding of the springs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two support blocks are disposed at upper and lower positions facing each other to fix compression line springs, then the springs can be fixed in place, but precise alignment of the support blocks is required which makes the apparatus difficult to manufacture, use, and maintain
Solution Approach 1:
The lower support block is made movable in the vertical direction, allowing it to automatically adjust its position to accommodate variations in spring dimensions and alignment tolerances. This dynamic adjustment capability enables reliable fixation without requiring precise initial alignment of the support blocks, thereby resolving the contradiction between stable fixation and ease of manufacture
Solution Approach 2:
The invention changes the positional parameter of the lower support block by making it vertically movable. This parameter change allows the support block to adapt to different spring sizes and alignment conditions, achieving stable fixation while eliminating the need for precise alignment during apparatus setup and operation
2Stability of the object's composition
If V-shaped depressions are formed in support blocks to stabilize coil springs, then the springs can be stably supported, but accurate alignment of the two supports is still required
Solution Approach 1:
The lower support block's vertical movability provides dynamic adaptation to alignment variations, allowing the V-shaped depression to maintain proper engagement with the spring regardless of initial alignment conditions. This eliminates the need for complex alignment settings while preserving the stabilizing effect of the V-shaped depression
3Reliability
If support blocks are precisely processed and set for accurate alignment, then stable fixation of springs is achieved, but the apparatus becomes difficult to manufacture and maintain
Solution Approach 1:
The movable lower support block compensates for wear and dimensional variations that occur during apparatus use and aging. This dynamic adjustment capability maintains stable fixation performance without requiring complex recalibration or realignment procedures, thereby improving ease of repair and maintenance while preserving reliable spring fixation

AI summary
Disclosed herein is an apparatus for grinding a compression line spring. The apparatus includes a lower chain conveyor (100), an upper chain conveyor (200), and grinding units (300). The lower chain conveyor includes chain units each having first support blocks (115) for supporting compression line springs. The upper chain conveyor includes chain units each having second support blocks (215) for compressing downward upper portions of the compression line springs and thus supporting the compression line springs. The grinding units grind seat surfaces formed on opposite ends of the compression line springs that are moved by the upper and lower chain conveyors. A V-shaped depression (115a) is formed in each first support block so that each of the compression line springs is seated onto the corresponding V-shaped depression. A lower surface (215a) of the second support block that compresses the compression line springs has a planar structure.
