[0021] A sealing sleeve 44 is fixedly installed in the middle position of the push plate 4. The sealing sleeve 44 is made of elastic wear-resistant rubber. A sleeve hole 45 is provided at the center position of the sealing sleeve 44. The inner wall of the sleeve hole 45 is slidably connected to the surface of the support column 34. The sealing sleeve 44 has the function of sealing and damping. An air avoidance hole 52 is opened at the center position of one end of the positioning block 5. One end of the air avoidance hole 52 is fixedly connected to a feed hole 53. One end of the feed hole 53 is fixedly connected to a threaded hole 54. The inner wall of the threaded hole 54 is threadedly connected to the external thread 36. The air avoidance hole 52 can prevent the positioning block 5 from colliding with the punch 12, and at the same time facilitate the punching waste to enter the positioning block 5. The feed hole 53 is trumpet-shaped to prevent the waste from accumulating in the positioning block 5 and facilitate the waste to be discharged downward.

[0022] A groove 33 is formed on the inner wall of the mounting groove 32, and the inner wall of the groove 33 is fixedly connected to one end of the spring 43. The number of the grooves 33 is the same as the number of the springs 43, and the grooves 33 can locate the supporting position of the spring 43. A center hole 14 is formed on the surface of the machine table 13, and a collecting bucket 18 is placed at the bottom of the machine table 13. The opening of the collecting bucket 18 is coaxial with the center hole 14, and the collecting bucket 18 can collect punching waste.

[0023] An arc-shaped portion 51 is provided at one end of the positioning block 5. The arc of the arc-shaped portion 51 is the same as the curvature of the inner wall of one end of the filter housing body 6. The arc-shaped portion 51 can not only prevent the filter housing body 6 from shaking horizontally, but also prevent one end of the filter housing body 6 from being deformed during punching. A slide groove 15 is provided on the surface of the machine table 13. The cross-sectional shape of the slide groove 15 is T-shaped. The slide groove 15 facilitates the sliding of one end of the bolt 17 and prevents one end of the bolt 17 from moving upward, thereby facilitating the positioning of the pressure plate 16.

[0024] A punching method of a filter housing processing punching device of the present invention is characterized by: P1. First, place the positioning mechanism 2 on the surface of the machine table 13 and make it coaxial with the center hole 14. When it is necessary to position the filter housing body 6 of different sizes, the positioning block 5 of the corresponding size can be assembled; P2. Then, insert one end of the bolt 17 into the slide groove 15 and move it in the direction of the positioning mechanism 2, so that the pressing plate 16 sleeved on the surface of the bolt 17 moves to contact the surface of the positioning seat 3. At this time, the positioning seat 3 can move horizontally on the surface of the machine table 13; P3, then start the punching device body 1 to control the punching block 11 to move slowly downward, so that the punch 12 moves downward to contact and position with the end surface of the positioning block 5, so that the positioning block 5 and the punch 12 are coaxial, and at the same time, the positioning seat 3 is driven to translate and adjust the position on the surface of the machine table 13; P4. Then, the positioned positioning mechanism 2 is locked by the bolt 17 and the pressing plate 16. The nut of the bolt 17 is rotated clockwise by a wrench, so that the pressing plate 16 clamps the positioning seat 3. P5. Then, the punching block 11 is controlled to move upward and reset, and the filter housing body 6 to be punched is placed on one end of the positioning block 5 for positioning. At the same time, the bottom of the filter housing body 6 contacts the surface of the push plate 4. Since the push plate 4 protrudes from the surface of the positioning seat 3, the top inner wall of the filter housing body 6 does not fit the top of the positioning block 5, leaving a gap. P6. Then operate the punching device body 1 to start punching; P7, at this time, the punch block 11 moves downward to drive the punch 12 to quickly move downward to punch the filter housing body 6, and the punching blade will be inserted into the air-avoiding hole 52; P8. The waste generated during punching enters the feeding hole 53 through the avoidance hole 52, and one end of the support column 34 is connected to the threaded hole 54, so that the feeding hole 35 is the same as the feeding hole 53, and then the waste passes downward through the feeding hole 35 and the center hole 14 in turn and falls into the collection bucket 18; P9. When punching holes at the same time, the punch 12 presses the filter housing body 6 downward, and the filter housing body 6 presses the push plate 4 downward. The push plate 4 moves downward so that the limit plate 41 presses the spring 43 downward, and the spring 43 is squeezed to generate a compressive elastic force; P10. After punching is completed, the punch 12 moves upward and resets. At this time, the spring 43 releases the elastic force, which resets the push plate 4 and pushes the filter housing body 6 upward, so that the inner wall of the filter housing body 6 will not fit and squeeze the top of the positioning block 5, making it easy to remove. Then the staff removes it, replaces the filter housing body 6 to be punched, and continues the punching work.

[0025] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
