Description

Technical Field

[0001] The utility model relates to the technical field of watch repair tools, in particular to a movement coaxial regulator for mechanical watches. Background Art

[0002] The speed adjustment of the mechanical automatic movement is achieved by changing the inertia and friction of the balance wheel. Specifically, the speed needle changes the inertia by adjusting the effective length and weight of the balance wheel, thereby adjusting the running speed of the movement; while the adjustment screw on the balance wheel can change the friction of the balance wheel, thereby further fine-tuning the speed of the movement.

[0003] The operator adjusts the counterweight screw with the help of a coaxial regulator. When the counterweight screw is tightened toward the center, the moment of inertia J of the balance wheel decreases, the vibration period decreases, and the meter runs faster. On the contrary, when the counterweight screw is adjusted in the opposite direction, the moment of inertia J of the balance wheel increases, the vibration period increases, and the meter runs slower. The existing coaxial regulator generally includes a handle, a weight plate, an indicator plate, and an adjustment cutter head. The handle, the indicator plate, and the adjustment cutter head are fixedly connected and arranged in sequence, and the weight plate rotates with the handle. The measurement scale on the weight plate remains unchanged. The measurement scale is used as a reference to determine the rotation angle of the indicator plate and the adjustment cutter head, thereby quantitatively adjusting the speed of the movement.

[0004] However, the existing coaxial converter has the following problems: 1. The stability of the weight plate is poor. During operation, the measuring scale is prone to shaking, and the operation remains unchanged; 2. The weight screws on different types of movement balance wheels have different models and specifications, and different adjustment heads are required to adjust the speed. The model and size of the sleeve hole of the adjustment head of the existing coaxial converter are fixed, and the applicability is low; 3. The components of the existing coaxial converter are mostly assembled from plastic parts, and the molding accuracy is low, resulting in the concentricity of the weight plate and the indicator plate, and the adjustment error of the coaxial converter is large. Therefore, it is necessary to improve it. Utility Model Content
