[0002] The main function of a motor filter is to protect the motor, ensure its normal operation, and extend its service life. Specifically, this can be divided into the following aspects: 1. Filtering impurities: Preventing dust, fibers, particles, and other debris from entering the motor, avoiding these impurities from adhering to key components such as windings and bearings, and preventing component wear or performance degradation; 2. Protecting core components: Reducing the erosion of the motor's internal structure by impurities, such as preventing dust from causing aging of the winding insulation layer, reducing the risk of short circuits, overheating, and other faults; 3. Maintaining heat dissipation efficiency: Keeping the motor's interior clean, ensuring the normal operation of the heat dissipation system (such as fans and heat sinks), avoiding the accumulation of impurities affecting heat dissipation, and preventing motor damage due to overheating.

[0003] Existing motor protective filters are generally manufactured using a stamping process, which has the main drawback of low millimeter-level machining precision, making them unsuitable for high-precision protective products. Therefore, we propose a high-precision protective process structure to solve the above problems. Utility Model Content

[0028] Example 1 like Figures 1-6 As shown, a high-precision protective process structure includes a lifting mechanism 1, a base 2, and a top seat 3. The lifting mechanism 1 is located above the top seat 3, and the top seat 3 is located above the base 2. A riveting assembly 5 is provided between the base 2 and the top seat 3. Guide assemblies 7 are symmetrically distributed on both sides of the riveting assembly 5. A positioning component 4 is adjustablely provided on the base 2. The lifting mechanism 1 uses a hydraulic press. The top seat 3 is positioned above the base 2. A riveting assembly 5 is installed between the base 2 and the top seat 3. Guide components 7 are symmetrically distributed on both sides of the riveting assembly 5. An adjustable positioning component 4 is installed on the base 2. In actual operation, the filter screen 9 is placed on the workpiece 8. The filter screen 9 is made of 0.5mm thick SUS304 stainless steel plate and is made using an etching process with a hole diameter of 0.65mm and a hole spacing of 0.95mm. Then, the workpiece 8 is placed on the riveting assembly 5. In component 5, the riveting component 5 is pressed down by the hydraulic press, so that the riveting component 5 rivets the filter screen 9 to the workpiece 8. This process structure can firmly fix the filter screen 9 to the workpiece 8. When the workpiece 8 with the filter screen 9 is subsequently installed on the motor, it can achieve high-precision protection and greatly improve the protection and ventilation and heat dissipation of the motor, so that the motor can cool down quickly. At the same time, the guide component 7 assists in the riveting work of the riveting component 5, and the positioning component 4 precisely controls the pressing height of the riveting component 5 when riveting.

[0029] Example 2 like Figure 1 , Figure 5As shown, the riveting assembly 5 also includes a mold base 51 and a mold handle 52. The mold handle 52 and the mold base 51 are on the same longitudinal axis. A riveting head 520 is provided on the mold handle 52.

The workpiece 8 is placed on the mold base 51, and the lifting mechanism 1 is controlled to press down. When the lifting mechanism 1 presses down, the lifting mechanism 1 uses a hydraulic press, and the mold handle 52 also presses down. The mold handle 52 contacts the workpiece 8 through the riveting head 520 at the bottom of the mold handle 52 to complete the riveting work. like Figure 4 , Figure 5 As shown, the guide assembly 7 includes a guide sleeve 72 and a guide rod 71. The guide rod 71 is telescopically inserted into the guide sleeve 72. This guiding method is more precise and avoids the riveting assembly 5 from twisting during riveting work, thereby improving the working accuracy of the riveting assembly 5. like Figure 4 As shown, at least one positioning component 4 is provided.

This is the basis for ensuring that the top seat 3 and the mold handle 52 can be reset after the riveting work is completed. like Figure 1As shown, the mold base 51 is fixed to the base 2 by screws, and the mold handle 52 is fixed to the top seat 3 by screws. The mold base 51 and the mold handle 52 can be replaced to accommodate different sizes of workpieces 8 and filter screens 9 for riveting.

[0030] Working principle: such as Figures 1-6 As shown, filter screen 9 is placed on workpiece 8. Filter screen 9 is made of 0.5mm thick SUS304 stainless steel plate and is made by etching process with a hole diameter of 0.65mm and a hole spacing of 0.95mm. Then, workpiece 8 is placed in riveting assembly 5. The riveting assembly 5 is pressed by lifting mechanism 1 so that the riveting assembly 5 rivets filter screen 9 to workpiece 8. This process structure can firmly fix filter screen 9 to workpiece 8. When workpiece 8 with filter screen 9 is installed on motor in the future, it can achieve high-precision protection and greatly improve the protection and ventilation and heat dissipation function of motor, so that motor can cool down quickly. At the same time, guide assembly 7 assists in the riveting work of riveting assembly 5.
