Tool for disassembling and assembling balance wheel shaft

Abstract

The invention provides a tool for disassembling and assembling a balance wheel shaft. The tool comprises a machine base, a reversing assembly, an impact assembly and an operation assembly. The machine base comprises a bearing table and a positioning sleeve, the positioning sleeve is arranged above the bearing table, and the positioning sleeve is connected with the bearing table through a connecting arm. The reversing assembly comprises an outer sleeve and an inner sleeve, the outer sleeve is arranged in the positioning sleeve in a height-adjustable mode, the inner sleeve is rotatably arranged in the outer sleeve, and a plurality of spiral grooves are formed in the inner side wall of an adjusting section of the inner sleeve. The impact assembly comprises a connecting piece and a punch, and the punch is detachably arranged on the bottom face of the connecting piece. The operation assembly comprises an impact hammer and a guide plunger, the impact hammer is arranged in the inner sleeve in a liftable mode, and the guide plunger is arranged in a mounting hole in the side wall of the impact hammer in a telescopic mode. According to the tool for disassembling and assembling the balance wheel shaft, the balance wheel shaft can evenly bear impact force in the disassembling and assembling process, and therefore the operation difficulty of workers is lowered.

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
