Problems solved by technology
[0002] In the prior art, there are unreasonable dimensional parameters of the movement stop seconds column assembled on the watch, and the movement stop seconds column tends to loosen after long-term use. At the same time, the movement processed by the prior art does not stop. The second column is often prone to machining accuracy that does not meet the requirements, so it is necessary to improve

Abstract
The invention discloses a method for machining a watch movement second stop column, and relates to the field of watch part machining. A second column body overall of an integrated structure is included and comprises a first second column and a second second column, and a transition shaft is connected between the lower end of the first second column and the upper end of the second second column. The first second column comprises a first circular truncated cone, a first column body, a second column body and a second circular truncated cone which are sequentially connected from top to bottom. The second second column comprises a third circular truncated cone, a third column, a fourth column and a fourth circular truncated cone which are sequentially connected from top to bottom. A dimension parameter of the watch movement second stop column is reasonable in setting, the watch movement second stop column can be accurately mounted on a mechanical watch, the watch movement second stop column machined through the method is high in product yield, the product yield can reach 90%, and therefore the method needs to be improved.
Description
technical field [0001] The invention relates to the field of watch parts processing, in particular to a method for processing a stop seconds column of a watch movement. Background technique [0002] In the prior art, there are unreasonable dimensional parameters of the movement stop seconds column assembled on the watch, and the movement stop seconds column tends to loosen after long-term use. At the same time, the movement processed by the prior art does not stop. The second column is often prone to machining accuracy that does not meet the requirements, so it is necessary to improve it. Contents of the invention [0003] The object of the present invention is to provide a method for processing the stop seconds column of a watch movement in order to overcome the disadvantages of the background technology. [0004] In order to achieve the above object, the technical solution of the present invention is: a method for processing the stop seconds column of a watch movement, ...
