Claims

[Scope of utility model registration request]

A work table 2 is rotatably supported in a predetermined direction, and has a plurality of spring holding holes 4 arranged at equal intervals on its outer periphery for holding a coil spring 86 to be ground, and a lower part of the work table 2. a spring mounting surface 32 on which the lower end of the coil spring 86 is placed; and a coil spring arranged to sandwich the work table 2 so as to be opposite to the movement path of each spring holding hole 4. A pair of upper and lower surface grindstones 58 for grinding.
70, an overlong spring detection device 6 located behind the grindstone 58.70 and detecting an overlong spring larger than a predetermined spring height in the spring holding hole 4;
A drive device drives the pair of upper and lower surface grindstones 58, 70 by a predetermined amount in a direction toward each other based on the detection signal of the overlong spring detection device 6, and detects the level of the polishing surface of the lower surface grindstone 70, The polished surface is the spring mounting surface 32
A level sensor 82 outputs a detection signal when the grinding wheel is located at substantially the same level as the grinding wheel 58, and a means for preventing the lower grinding wheel 70 from being driven in the direction of the upper grinding wheel 58 based on the output signal of the level sensor 82. Automatic grinding wheel position correction device for spring grinding machines.
