Crimping tool for use in robot, has tensile spring whose elastic effect is removed when nut contacts sliding support, and load cell provided in bottom part of blind hole that is formed on support

摘要

The tool has an outer panel plate (2) whose edge is provided with an inner panel plate (3). A roller (4) is mounted on a sliding support (5) and a head part (6) of a robot. A tensile spring (10) is connected to the support, and controlled by a spindle (12) and a nut (13). The spindle is rotated by a servomotor (14) and connected to the head part of the robot. The nut is moved by varying the length of the spring. A load cell (20) is provided in a bottom part of a blind hole (11) that is formed on the support. The elastic effect of the spring is removed when the nut contacts the support.
