A tool for disassembling and assembling a balance wheel shaft

Abstract

The invention provides a tool for disassembling and assembling a balance wheel shaft, which includes a machine base, a reversing component, an impact component and an operating component. The machine base includes a bearing platform and a positioning sleeve, the positioning sleeve is arranged above the bearing platform, and the positioning sleeve is connected with the bearing platform through a connecting arm. The reversing assembly includes an outer sleeve and an inner sleeve. The height of the outer sleeve is adjustable inside the positioning sleeve, the inner sleeve is rotatably arranged inside the outer sleeve, and the inner side wall of the adjustment section of the inner sleeve is provided with There are multiple helical grooves. The impact assembly includes a connecting piece and a punch, and the punch is detachably arranged on the bottom surface of the connecting piece. The operating assembly includes an impact hammer and a guide plunger, the impact hammer can be raised and lowered inside the inner sleeve, and the guide plunger is telescopically arranged inside the installation hole on the side wall of the impact hammer. The tool for disassembling and assembling the balance wheel shaft according to the invention can make the balance wheel shaft bear the impact force evenly during the disassembling and assembling process, thereby reducing the operation difficulty of the staff.

Description

technical field [0001] The invention belongs to the field of watch parts processing equipment, and particularly relates to a tool for disassembling and assembling a balance wheel shaft. Background technique [0002] The balance wheel hairspring system is the core component inside the watch movement. When working, the compression and relaxation of the hairspring will drive the balance wheel to rotate and oscillate. while walking. [0003] In order to reduce the frictional resistance of the rotation of the balance wheel, both ends of the common balance wheel shaft are provided with shaft tips with small diameters. However, with the growth of the movement cycle, the small tip of the balance shaft will inevitably wear out. When the movement is subjected to severe vibration, the tip of the balance shaft may be bent or broken. After the tip of the balance wheel is damaged, the rotation and oscillation period of the balance wheel will be affected, which will affect the accuracy o...

Problems solved by technology

However, the multiple rotations of the balance wheel cannot guarantee a uniform rotation angle, so it still cannot ensure the uniform distribution of the impact force

In addition, when using a hammer to strike the punch for many times in a row, the impact point of the hammer may also deviate from the axis of the punch, which will aggravate the uneven distribution of the impact force, which will further affect the follow-up of the balance wheel. Effect
