Tool, system and method for the screwing of helical compression springs to a screw plate spring

摘要

The arrangement has two tools (1) comprising respective cylindrical tool bodies (2). The tool bodies comprise a transit (3) for receiving a cylindrical arbor (5). The transit is arranged concentric to a rotational axis (7) around which one tool rotates opposite to another tool. A claw (12) is formed adjacent to the transit at an end surface (9), for clamping an end of a helical compression spring. The claw comprises a projection in a rotational direction. The arbor partially exhibits a constant cross-section. The spring is fitted on an outer surface of the arbor with small clearance. Independent claims are also included for the following: (1) a system for fastening a helical compression spring to a helical plate spring (2) a method for fastening a helical compression spring to a helical plate spring.
