Switch mechanism automatic pin pressing device and switch mechanism running-in device using same

Abstract

The invention relates to the field of special equipment for manufacturing a switch mechanism, in particular to a switch mechanism automatic pin pressing device and a switch mechanism running-in deviceusing the same. The switch mechanism automatic pin pressing device comprises a base, wherein a fixing structure for fixing the switch mechanism and a pin pressing mechanism are arranged on the base,and the pin pressing mechanism is provided with a pushing end for pushing a roll pin; and a protective piece is arranged on the base, and the protective piece is provided with an inner concave wall. When the pin is pressed by the switching mechanism, the switch mechanism is fixed on the base through the fixing structure, the pin pressing mechanism on the base pushes the roll pin to a pin hole in amanual opening and closing operating shaft through the pushing end, the pushing end exerts a certain pushing force on the manual opening and closing operating shaft through the roll pin, and the inner concave wall of the protective piece arranged on the base makes contact with the outer wall of the manual opening and closing operating shaft, so that the protective piece provides a supporting force opposite to the pushing force for the manual opening and closing operating shaft, and the stress of the operating shaft is more uniform without being deformed by stress.

Description

technical field [0001] The invention relates to the field of special equipment for manufacturing switch mechanisms, in particular to an automatic pin-pressing device for a switch mechanism and a running-in device for a switch mechanism using the device. Background technique [0002] The existing switch mechanism is equipped with a manual opening and closing operation shaft, and the end of the manual opening and closing operation shaft extends out of the switch mechanism. In order to facilitate the use of the operating handle to apply force to the manual opening and closing operation shaft to For the operation of manual opening and closing, the end of the manual opening and closing operation shaft protruding from the surface of the switch mechanism is set into a cylindrical structure, and two corresponding pin holes are opened in the radial direction of the cylindrical structure. Roll pin installed. When manual opening and closing is required, use the operating handle to ope...

AI Technical Summary

Problems solved by technology

[0004] If the above spring pin automatic pressing device is applied to the pin pressing operation of the switch mechanism, there is a technical problem, specifically: since the manual opening and closing operation shaft of the switch mechanism protrudes from the surface of the switch mechanism, the rolling pin is pressed When it enters the pin hole of the manual opening and closing operation shaft, it will generate a thrust force on the manual opening and closing operation shaft. If the thrust is too large, it will deform the manual opening and closing operation shaft, which will affect the manufacturing accuracy and quality of the switch mechanism. and the effect of using
