Description

Technical Field

[0001] This utility model relates to the field of oil filter elements, and in particular to a device for measuring the pull-out force of oil filter end caps and bodies. Background Technology

[0002] In the production process of oil filters, the end cap and the body are usually connected by bonding or other methods. If the pull-out force is insufficient, the pressure and vibration of the oil during engine operation may cause the end cap to separate from the body, resulting in oil leakage and ineffective oil filtration, which in turn affects the normal operation of the engine. In the existing technology, pull claws are often used to fix the end cap and body when measuring the pull-out force. However, pull claws are not suitable for some oil filters with special structures. When measuring the pull-out force, the filter element is prone to displacement and shaking, resulting in inaccurate pull-out force values ​​that cannot truly reflect the actual pull-out force between the end cap and the body, thus affecting the reliability and accuracy of the measurement results.

[0003] Therefore, it is necessary to propose a device for measuring the pull-out force of the oil filter end cap and body to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a pull-out force measuring device for oil filter end caps and bodies, in order to solve the problem that when using pull claws to measure the pull-out force of some oil filters with special structures, the filter element is prone to displacement and shaking, resulting in inaccurate measured pull-out force values.
