Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to an auxiliary clamp for detecting vulcanized diaphragms. Background Art

[0002] The vulcanized diaphragm is a metal part with a circular center. The vulcanized rubber extends to the periphery of the metal part to form a circular thin sheet with an arc surface, which is similar to a disc-shaped structure. The vulcanized diaphragm after production has requirements not only for its temperature, composition and hardness, but also for whether the diaphragm surface has scratches, bubbles and cracks. The scratches and cracks on the diaphragm surface are difficult to observe under normal circumstances and usually need to be stretched to observe or detect them.

[0003] For example, the utility model patent with announcement number CN206420640U discloses an auxiliary fixture for testing vulcanized diaphragms. When performing a tensile test on a vulcanized diaphragm, the fixture places the vulcanized diaphragm in a positioning hole of a diaphragm plate, and the thickness of the diaphragm is greater than the thickness of the positioning hole. Then, a lower pressure plate presses down on the top of the diaphragm, and a cylinder on the side drives the diaphragm plate to move parallely, thereby stretching the vulcanized diaphragm. The operator can observe whether the vulcanized diaphragm has defects from the top.

[0004] However, when the device stretches the vulcanized diaphragm, because there is a lower pressure plate pressing it from above, when the cylinder drives the diaphragm plate to move backward, the lower pressure plate presses the upper half of the diaphragm, and the lower part of the diaphragm is in the positioning hole. During stretching, the upper part of the diaphragm may be stationary, and when the lower part moves with the diaphragm plate, if the moving distance is long, the lower part of the diaphragm will slip away from the positioning hole, thereby affecting subsequent diaphragm detection and observation. Utility Model Content

[0005] The utility model provides an auxiliary clamp for detecting a vulcanized diaphragm, which solves the problem in the prior art that the diaphragm may be separated from a positioning hole when the diaphragm is stretched.

[0006] The technical solution of the utility model is as follows:

[0016] In summary, the fixture can extrude and block the vulcanized diaphragm when it is stretched through the mutual cooperation between the workbench, stretching assembly, placement plate, mounting plate, extrusion assembly and blocking assembly, thereby preventing the vulcanized diaphragm from separating from the placement plate during the stretching process.
