Cylindrical helical spring characteristic measuring device - has scale between spring and short end of lever which is connected to weighing and support blades

摘要

The device includes a micrometer and a lever transmission mechanism. A scale (3) is arranged between the short end of one lever and the spring. The lever (2) has a weighing blade (4) and support blade (5). The long arm of the lever has a tip which matches the tip of an indicator. The weighing blade moves in prismatic slots in a bearing (18). The scale is attached to a measurement table (7) with two mutually perpendicularly radial slots (7'). Movable supports (8) can be fixed in the slots in positions corresp. to the outer spring dia. USE/ADVANTAGE - E.g. for measuring springs for use in factories and laboratories. Simplified construction.
