Description

Technical Field

[0001] This utility model relates to the field of movement processing technology, and in particular to a riveting device for pressure gauge movements. Background Technology

[0002] The pressure gauge movement is the core transmission component that enables pressure signal conversion and pointer indication. It typically consists of the movement body, gear set, pointer shaft, and connecting parts. These parts are assembled and fixed using riveting to ensure structural stability and accuracy during transmission. Riveting is a critical process in the production and assembly of the pressure gauge movement. The procedure involves first placing the movement parts in their designed positions, then applying axial pressure to the pre-set riveting points using a riveting device. This causes plastic deformation of the riveting components (such as rivets and rivets), thus securing the disparate parts together. When riveting the central column, pointer, and other components, the movement needs to be calibrated to ensure no displacement of the parts during riveting and to achieve reliable riveting through stable pressure output.

[0003] Existing riveting devices for pressure gauge movements have insufficient centering and calibration capabilities when precisely clamping the movement. They cannot quickly and conveniently center and fix the movement, resulting in poor clamping convenience and accuracy. Manual operation errors can easily lead to misalignment of the riveting points between the riveted parts and the movement, affecting riveting accuracy. Furthermore, the synchronous movement of the riveted parts is inconvenient, further compromising both accuracy and ease of operation. The inability to effectively control the synchronous centering movement of the riveted components further impacts riveting accuracy and operational efficiency. Therefore, we propose a riveting device for pressure gauge movements to address these issues. Utility Model Content
