Description

A pull head spring piece rewinding and unwinding correction device

Technical Field

The utility model relates to the technical field of slider springs, in particular to a slider spring reeling and unreeling deviation correction device.

Background Art

The pull head spring usually refers to a small metal part in some electronic or mechanical equipment. It is usually made of spring steel or other materials with good elasticity. It is mainly used to assist the switch action of the equipment or fix certain parts. When processing the pull head spring, the pull head spring retracting and unreeling correction device will be used;

For example, Chinese patent CN217201050U discloses a pull head spring sheet winding and unwinding correction device. The device cooperates with a worm and a half gear. When the spring sheet coil is wound and unwound at a large tilt angle, the worm is driven to rotate by shaking the handle, and the worm drives the balance support plate to adjust the tilt. After tilting to a suitable position, if the pull head spring sheet still tilts a little, it can be fine-tuned by adjusting the butterfly nut installed on the fine-tuning block to balance the coil.

However, there are certain defects in this patent. When the coil is offset, the operator needs to adjust the balance support plate according to the offset angle. The operator needs to make repeated adjustments during the process. At the same time, the operator also needs to observe the equipment all the time, which is time-consuming and labor-intensive.
