Description

Technical Field

[0001] The utility model relates to the technical field of sealing diaphragm quality detection equipment, in particular to a positioning fixture for sealing diaphragm surface quality detection. Background Art

[0002] Diaphragm seals have two main tasks: separation of measuring instruments and process media, and transmission of pressure to the measuring instrument. When the process media should not come into contact with the pressure-bearing parts of the measuring instrument, diaphragm seals (also called chemical seals or remote seals) are used for pressure measurement. The process side of the diaphragm is isolated by a flexible diaphragm. The internal space between the diaphragm and the pressure measuring instrument is completely filled with system filling fluid. However, existing sealing diaphragm quality inspection equipment has some shortcomings, such as:

[0003] Publication No.: CN1115227C discloses a clamping device, which includes a substantially C-shaped frame, preferably with a long inner arm distance, and the frame uses its free side arm end to clamp a tool such as a riveting, bonding or welding component. The clamp includes a truss or frame, which includes inner and outer C-shaped frames and a plurality of oblique supports connecting them. The frame and the oblique supports are arranged into a plurality of interconnected triangular parts, and the connection points thereof are designed as connectors or joints; the outer C-shaped frame is designed to bear only thrust. Since the edge of the device is a circular structure, during the quality inspection process, due to the small force-bearing area of ​​the clamping claw structure, only a small area of ​​the diaphragm can be fixed, and the soft nature of the rubber material can cause the diaphragm to deform and shift, making it difficult to place it accurately.
