Balance spring pushing device

Abstract

The invention discloses a balance spring pushing device which comprises a workbench, wherein a sliding plate component is arranged on the workbench and is used for loading a balance spring and transmitting the balance spring for a short distance; in a transmission process, the balance spring is put on a moving plate on the sliding plate component; the balance spring is transferred and loaded by horizontally moving the moving plate on a guide rail. The transferring loading manner is stable and firm; the vibration is small in the transferring loading process; the transmission of precise small parts is met; a pushing component arranged on the upper part of the sliding plate component is used for driving the moving plate to transfer and load; the pushing component is slowly driven by a stepping motor, so that the moving plate is moved at constant speed in a moving process and is stable and firm; buffering components arranged at the two ends between the slide rails have a buffering function and are used for buffering and damping the moving plate when the moving plate reciprocates to a terminal point and is about to stop; the vibration is reduced when the moving plate is stopped; the vibration of the balance spring in the moving plate is reduced; the abrasion of the balance spring is reduced.

Description

technical field [0001] The invention relates to a watch processing auxiliary mechanism, in particular to a hairspring pushing device. Background technique [0002] The hairspring is one of the main parts that determine the vibration frequency in the movement of the watch. It is a very thin spring, usually made of steel, coiled around the balance wheel. The change in the effective length of the hairspring determines the moment of inertia and the amplitude period of the balance wheel, and the hairspring is one of the factors that affect the accuracy of travel time. The Archimedes spiral coil spring made of metal filaments through cold rolling, winding and shaping is an elastic element that can generate reaction torque. The hairspring and the balance wheel form a vibration system to obtain a certain vibration period to achieve the purpose of accurate timing. After the hairspring is produced, it needs to be assembled precisely. During the assembly process, the cooperation of v...

Problems solved by technology

After the hairspring is produced, it needs to be assembled precisely. During the assembly process, the cooperation of various staff is required, and the hairspring needs to be transferred to the hands of each staff by short-distance precision transfer equipment. The current transfer equipment The load capacity is small, relatively rough, and cannot meet the demand
