Description

TECHNICAL FIELD

[0001] The utility model relates to filter cartridge fixing equipment technical field, specifically is a filter cartridge fixing frock. BACKGROUND

[0002] Filter cartridges play a crucial role in the filtration process of marine fuel and industrial oil. With increasing global concerns about environmental protection and energy efficiency, the design and manufacturing technology of filter cartridges are continuously advancing to meet higher performance and reliability requirements. Traditional machining processes usually place the workpiece flat on the machine tool workbench and fix it with a pressing plate and bolts. Although this method can complete the machining task to some extent, it has many shortcomings in actual operation.

[0003] Firstly, the shape of the filter cartridge is cylindrical, which makes it extremely difficult to ensure straightness when clamping the workpiece on the flat plate. Due to the center of gravity and shape characteristics of the workpiece, the traditional fixing method often causes displacement of the workpiece during machining, thereby affecting the machining accuracy. This lack of accuracy not only leads to a decrease in the filtration performance of the filter cartridge, but also affects the overall system efficiency, increasing the cost of subsequent maintenance and replacement.

[0004] Secondly, the traditional clamping method is prone to causing pressure marks on the surface of the workpiece. Due to the use of a pressing plate and bolts for fixing, the pressure applied to the surface of the workpiece is often uneven, causing deformation or scratches on the workpiece during the fixing process. This surface damage not only affects the appearance of the filter cartridge, but also may affect its sealing performance and durability in actual application, thereby reducing the overall quality of the product.

[0005] To solve the above problems, a new frock clamping system has been introduced in modern machining processes. INVENTION CONTENTS
