Abstract
Description
Technical Field
[0001] The utility model relates to the field of switch product assembly, in particular to a reed-type micro switch fine adjustment device, which is mainly used for accurately adjusting the deformation amount of the micro switch reed after installation. Background Art
[0002] Micro switches have the characteristics of small electrical contact spacing, fast action, and high sensitivity, and are widely used in aerospace, instrumentation and other fields. Micro switches are mainly composed of buttons, rocker arms, supports, housings, contacts, reeds, etc. Among them, reed assembly is the key difficulty of micro switches. Due to the small size and high precision of micro switch components, the reed is particularly prone to plastic deformation or the deformation degree is too small during the assembly process, resulting in the contact pressure of the moving contact not meeting the design expectations. The contact pressure of the moving contact is provided by the deformation of the reed. Currently, the deformation of the reed is adjusted based on manual experience. When manually adjusting the reed, the deformation is difficult to control, resulting in poor consistency in the action characteristic parameters of the micro switch. Utility Model Content

The bearing is assembled into the bracket, and the bracket and the adjustment device are fixed to the base plate by screws. The shaft of the differential head passes through the bearing hole and is fixed to the bracket. One end of the coupling clamps the shaft on the differential head, and the other end clamps the adjustment screw of the micro switch adjustment device. Rotating the screw on the differential head drives the adjustment screw on the adjustment device to move simultaneously. The differential head is provided with a display screen, which can directly display the displacement and accurately control the moving distance of the adjustment screw on the adjustment device, thereby achieving the purpose of accurately controlling the deformation amount of the reed.
