Description

Technical Field

[0001] The utility model relates to the field of button production, in particular to a rotor oiling device. Background Art

[0002] In the production process of precision push button micro switches, the production and assembly process of certain parts of the buttons requires the surface of the workpiece to be oiled for subsequent operations.

[0003] In the case of Figure 3 The workpiece shown includes a rotor and a reed. When the reed is oiled, the oiling nozzle needs to rotate around the rotor axis to make a circular motion. Because the reed itself has elastic deformation characteristics, the reed will be deformed and pressed down during the oiling operation, and the oil sprayed from the oil nozzle is difficult to completely cover the contact point at the end of the reed. Since the three reeds are arranged in a ring array and integrally formed on the same metal sheet, there is a hole for oiling in the center of the oiling nozzle. Therefore, each rotor needs to be oiled three times. The method of using an oiling nozzle to oil the reeds one by one is too inefficient. And due to the small size of the rotor and the spring, it is difficult for the oiling nozzle to approach the reed, and the oiling effect is poor.

[0004] Therefore, an oiling device capable of simultaneously oiling three reeds is proposed, so as to improve the oiling effect and efficiency. Utility Model Content
