Problems solved by technology
In this mass production situation, the traditional measuring instrument has a complex structure, the test speed is very slow, and the stiffness of the standard coil spring will change with the length of time it is used, so there cannot be a unified standard for the measurement data, often The curves measured by the same spring on different measuring instruments will have differences, which will affect the accuracy of the performance analysis of the spring

The invention discloses a tester for the moment of a mainspring; the tester comprises a mechanical part and an electric part, wherein the mechanical part is used for finishing transmission and fixation functions; the electric part is used for controlling the winding number and angle of a stepping motor, collecting the output moment of a sensor in real time and realizing the printing of a moment curve; the tester for the moment of the mainspring avoids the shortcoming of the traditional tester for the moment of the mainspring and can carry out full-automatic testing on the performance of the mainspring and measure a performance curve of the mainspring rapidly, stably and accurately, thereby completely changing the traditional measurement mode which is realized by using the physical elastic deformation and having very important significance for the detection of the mainspring and the performance of the mainspring by clock production manufactures.
Description
technical field [0001] The invention relates to the technical field of clocks and watches, in particular to a spring torque tester. Background technique [0002] The mainspring is the energy source of a mechanical watch, and its quality directly affects the travel time accuracy of the watch. For springs, it is generally required to have small volume, large torque, small torque drop, fatigue resistance, strong anti-magnetic properties and good corrosion resistance. In the production of clocks and watches, it is necessary to measure the torque curve of the mainspring, which is the most direct expression of the performance of the mainspring. [0003] In related manufacturers such as springs and clocks and watches, it is necessary to measure the torque curve of the spring. The traditional measurement method is to compare the stiffness of the spring with the standard coil spring. In this mass production situation, due to the complex structure of traditional measuring instrument...
