Description

Technical Field

[0001] The present application relates to the technical field of fasteners, and in particular to a tensile testing device for fastener processing. Background Art

[0002] Fasteners are a type of mechanical parts used for fastening and connection and are extremely widely used. Fasteners are widely used in a wide range of industries, including energy, electronics, electrical appliances, machinery, chemicals, metallurgy, molds, hydraulics, etc. Various fasteners can be seen on various machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, chemicals, instruments and supplies, etc. They are the most widely used mechanical basic parts.

[0003] For example, a Chinese utility model patent with publication number "CN217981066U" discloses a tensile testing device for fastener processing. The utility model can store fasteners that need to be tested through a storage plate, and the sliding between the storage plate and the workbench makes it easy for users to take them out. The baffle can be opened by a hinge, so that the inside of the device can be cleaned and maintained, so that the device does not need to spend extra time to disassemble it when cleaning or repairing. The elastic force of the reset spring enables the adjustment block to clamp the fastener on the side plate, so that the device can automatically position and clamp the fastener. At the same time, the elasticity of the reset spring enables the device to be adjusted according to the size of the fastener, thereby improving the flexibility of the device structure. The hydraulic rod can drive the cross plate to rise and fall, so that the device automatically stretches the fastener.

[0004] The above patent can be applied to fasteners of different sizes, but the device clamps the fasteners by the elastic force of the spring and the clamp used by the device is rectangular, which makes it difficult to effectively clamp the fasteners. When the device is used, the fasteners may easily fall off the device, affecting the tensile test. Utility Model Content
