Description

Technical Field

[0001] The present application relates to the technical field of hairspring welding, and in particular to a welding tool for instrument hairsprings. Background Art

[0002] Instrument hairspring welding jigs are usually used in the manufacturing and repair of micro-instruments or precision instruments. These instruments require a high degree of accuracy and reliability. The jig must provide sufficient stability to ensure that the position of the hairspring does not shift during the welding process. Accurate position control is key because the position of the hairspring has a direct impact on the performance and accuracy of the instrument. Sometimes, the welding position may need to be fine-tuned, so the jig may need to provide a certain degree of adjustability to allow for fine adjustments.

In order to ensure uniform welding of the welding point, it is necessary to control the position change of the welding needle. For this reason, an instrument hairspring welding tool is needed to solve the existing deficiencies. Utility Model Content
