Automatic plate pushing device of balance springs

Abstract

The invention discloses an automatic plate pushing device of balance springs. The automatic plate pushing device comprises a workbench, wherein a sliding plate assembly is arranged on the workbench and is used for placing of the balance springs and short-distance transmission of the balance springs; during transmission, the balance springs are placed on a moving plate on the sliding plate assembly; the balance springs are moved through horizontal motion of the moving plate on guide rails; the moving manner is quite stable; during the moving process, the vibration is low, and transmission of precise small parts is met; a pushing assembly arranged at the upper part of the sliding plate assembly is used for pushing the moving plate to move; the pushing assembly enables the moving plate to maintain constant-speed motion during moving through gentle driving of a stepping motor, and moving is quite stable; a storage group arranged on the moving plate is provided with a plurality of storage grooves used for placing the balance springs, a plurality of balance springs can be moved at a time, and the device is convenient and efficient; and during the transmission process, high pressure springs arranged between supporting rods and slide rails have a buffer function, vibration generated by the moving plate during reciprocating motion is reduced by the high pressure springs, and the stableness degree of operation of the device is improved.

Description

technical field [0001] The invention relates to an auxiliary mechanism for watch processing, in particular to a hairspring automatic pushing plate 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,...
