Problems solved by technology

At present, by returning to consumers to understand the experimental data in the actual wearing process, not only the data collection cycle is long, but also affected by consumers' different wearing habits and wearing environments, the experimental data provided are not professional and reliable enough, and there is no regularity. Can not meet the research on the wear of each system of the movement

Embodiment 1

[0043] In this embodiment, a method for quickly detecting the fatigue resistance of a mechanical watch spring comprises the following steps:

[0044] 1) Before the test, perform a performance test on the movement. The test item is the continuation of the movement time of the movement. The movement is fully loaded and compared with the standard timepiece. Record the start time of the movement at this time, which is March. At 15 o'clock in the afternoon on the 15th, place the movement still, without any vibration or shaking, and carry out the actual movement on the surface. When the movement stops, compare it with the standard timepiece and record the stop time at this time. It is at 9 o'clock in the morning on March 17th, calculate the time difference before and after, and get the continuous travel time data T of the movement 0 for 42 hours.

[0045] 2) In step 1), the meaning of continuation of travel time is: when the mainspring is fully wound and fully relaxed, the stored e...

Embodiment 2

[0057] In this embodiment: a method for quickly detecting the fatigue resistance of a mechanical watch clockwork, comprising the following steps:

[0058] 1) Before the test, conduct a performance test on the movement. The test item is the continuation of the movement time of the movement. The movement is fully loaded and compared with the standard timepiece. Record the start time of the movement at this time, which is April. At 15:00 p.m. on the 3rd, place the movement still, without any vibration or shaking, and carry out the real movement of the position on the surface. When the movement stops, compare it with the standard timepiece and record the stop time at this time. It is 12 o'clock in the morning of April 05th, calculate the time difference before and after, and get the continuous travel time data T of the movement 0 for 45 hours.

[0059] 2) In step 1), the meaning of continuous travel time is: when the mainspring is fully wound and fully relaxed, the stored energy ...

Abstract

The invention provides a method for rapidly detecting fatigue resistance of a mechanical watch spring. The method comprises the following steps: Step 1, performance of a movement is detected before the test; Step 2, according to measured continued travel time data, it is roughly calculated that the spring operates for 1-20 years, and number of times of tightening the spring until the spring is completely loosened is calculated; Step 3, on the precondition of not damaging the movement part, the mechanical watch spring device is dismantled; Step 4, by a torsionmeter, the spring device is rapidly wound up and quickly releases energy, and torsion value of tightening the spring is recorded; and Step 5, when the spring fast-travel time reaches 1-20 years, the spring device is installed, and a performance test is carried out so as to obtain performance change data after fast-travel of the spring. By the method, a long travel test of the mechanical watch spring is carried out, and fatigue wear phenomenon caused by repeated tightening of the spring during the actual use process is simulated. Therefore, whether the spring is stable during a long-term use process is judged rapidly. The method is used for verify long-term travel reliability of a spring prepared from a new material.

Description

technical field [0001] The invention relates to the technical field of watch testing in the light industry manufacturing industry, in particular to a method for quickly testing the fatigue resistance of a mechanical watch spring. Background technique [0002] The operating mechanism of a mechanical watch can be divided into six parts: the winding needle system, the prime mover system, the transmission system, the escapement system, the balance spring and the pointer system. Among them, the three systems of prime mover system, transmission system and balance spring all have certain fatigue and wear phenomena when they run for a long time. At present, there is no reliable detection method to quickly detect each system in the mechanical movement. Reliability and approximate service life after travel time. At present, by returning to consumers to understand the experimental data in the actual wearing process, not only the data collection cycle is long, but also affected by cons...
