Abstract

See full text

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.
