Description

Technical Field

[0001] This utility model relates to the field of filter element processing technology, and in particular to a fixture for filter element processing. Background Technology

[0002] As a key component with filtration and purification functions, filter elements are widely used in many fields such as gas-liquid separation, solid-liquid separation, exhaust dust filtration, and environmental protection. In industries such as machinery, electronics, petroleum, chemical, and transportation, filter elements made of different materials, such as stainless steel, copper, titanium, Hastelloy, and plastic, play a vital role.

[0003] After the filter element is manufactured, its coaxiality needs to be strictly controlled to ensure installation stability and achieve precise matching between the filter element and the housing. However, coaxiality detection and control currently face many challenges in filter element production. The commonly used process involves a fully separate welding process for the filter paper and end caps. During the downward pressing welding process, slight misalignments can easily occur, causing the centers of the upper and lower end caps to deviate, resulting in coaxiality deviations. This not only affects the installation accuracy of the filter element and reduces product quality, but may also lead to problems such as leakage and poor filtration during use, increasing production and maintenance costs.

[0004] To address the aforementioned issues, some companies have attempted to use traditional fixtures. However, these fixtures are often complex in structure, inconvenient to operate, and have limited calibration accuracy, failing to meet the demands of modern, efficient, and high-precision production. Therefore, it is necessary to design a fixture for filter element processing. Summary of the Invention

[0005] This utility model provides a fixture for filter element processing to solve the problem in the prior art where the centers of the upper and lower end caps are not aligned due to welding misalignment, which affects the processing accuracy of the filter element. It enables precise positioning and fixing of the end caps and filter paper to ensure the coaxiality of the centers of the upper and lower end caps of the filter element, thereby improving the processing accuracy of the filter element.
