Clamping balance lockable regulator pin fine tuning mechanism

Abstract

The invention discloses a clamping balance lockable regulator pin fine tuning mechanism including a balance cock, a hairspring outer pile, a hairspring, an antivibrator, a balance, and an regulator pin mechanism, the balance cock is fixed on the movement of a mechanical watch, the inner end of the spring is connected at the balance shaft, the regulator pin mechanism includes an regulator pin body, a hairspring clamp, an regulator pin connecting rod, and a fine tuning screw with a big cap and a small eccentric shaft, the hairspring outer pile, the regulator pin body, and the regulator pin connecting rod sleeve the balance cock via the antivibrator, the hairspring penetrates into the hairspring clamp, the outer end of the hairspring is fixedly connected with the hairspring outer pile, and the hairspring clamp is composed of a hairspring fixed lock flap and a hairspring movable lock flap. The hairspring outer pile and the regulator pin can be fixed and also are convenient to adjust, the hairspring and the hairspring clamp are firmly clamped, so that the rapid coarse registration adjustment and fine registration adjustment of the regulator pin position can be facilitated, the structure is reasonable, and the efficiency for watch time-travelling accuracy adjustment and calibration is improved.

Description

Technical field [0001] The invention relates to the technical field of mechanical watches with card degrees, in particular to a fine-adjusting mechanism for locking fast and slow needles of a card degree balance wheel. Background technique [0002] The adjustment mechanism of the balance wheel of a mechanical watch with card degree is composed of movable outer stakes and fast and slow needles. Because the outer stakes and fast and slow needles cannot be fixed, they are often caused by external force factors such as knocks and bumps during use: (1) External stakes Displacement occurs, causing the watch to have an isochronous error, causing a deflection phenomenon; (2) The speed needle produces displacement, which changes the length of the hairspring that is effectively used, and the watch moves faster or slower. In addition, the speed needle of the balance wheel adjustment mechanism of the mechanical watch with card degree is convenient for adjustment. There is a certain gap betwe...

[0002] The travel time adjustment mechanism of the balance wheel of a mechanical watch with a card is composed of a movable outer stake and a fast and slow needle. Since the outer stake and the fast and slow needle cannot be fixed, it is often caused by external factors such as bumps and bumps during use: (1) The external stake Displacement occurs, which causes the isochronous error of the watch to cause deflection; (2) The displacement of the fast and slow hands causes the length of the hairspring to be effectively used to change, and the watch travels faster or slower

In addition, in order to facilitate the adjustment of the speed needle of the balance wheel travel time adjustment mechanism of the mechanical watch with card, there is a certain gap between the hairspring and the speed needle clip, which causes the hairspring to sometimes stick to the inner clip, sometimes to the outer clip, or just stick to the outer clip during the vibration process. Attach one side of the clip, or not attach the clip, so that the actual working length of the balance spring changes at any time, resulting in unstable vibration cycle of the balance wheel, resulting in inaccurate travel time of the watch
