[0037] Meanwhile, the positioning plate 2 of this tooling is detachably installed on the frame 1, and the positioning plate 2 is supported by the horizontal adjustment mechanism 4 and the vertical adjustment mechanism 5. In actual use, different positioning plates 2 can be replaced to position the mounting bracket 6 according to different models of filter assemblies. It is suitable for the assembly of mounting brackets for different air filter assemblies, with a wider range of applications and stronger versatility.

[0038] Preferably, a support rod 8 is provided on the frame 1, which is mounted in the middle of the frame 1. A groove 9 with a cross-section that is wider on the inside and narrower on the outside is provided on the support rod 8.

[0040] Preferably, the positioning assembly includes two pairs of positioning posts 14 arranged at both ends of the positioning plate 2. Each pair of positioning posts 14 consists of two posts 14. The distance between the two pairs of positioning posts 14 is equal to the relative distance between the two mounting brackets 6 on the air filter 7. This ensures that after the two mounting brackets 6 are positioned on the positioning plate 2, the relative distance between them is equal to the relative distance between the two mounting brackets 6 on the air filter 7 after the air filter assembly is assembled, thereby ensuring installation accuracy. The distance between the two positioning posts 14 in each pair is equal to the distance between the two bolt holes of the mounting bracket 6, ensuring that the positioning posts 14 can be aligned with the bolt holes of the mounting bracket 6 to achieve positioning installation. Furthermore, the positioning posts 14 are detachably mounted on the positioning plate 2, such as by threaded connection to the positioning plate 2, or the positioning posts 14 are stepped cylindrical pins that are inserted into the positioning plate 2 by a pin engagement, facilitating the replacement of positioning posts 14 of different diameters and making use more convenient. In other embodiments, the positioning component may also be a groove on the positioning plate 2 that is adapted to the width of the mounting bracket 6, thereby determining the relative distance between the two mounting brackets 6.

[0041] Preferably, the clamping assembly includes a corner cylinder 15 and a pressure block 16. The corner cylinders 15 are mounted in pairs on the support seats 3 on both sides of the mounting bracket 6, that is, each mounting bracket 6 corresponds to four corner cylinders 15.

The vertical rod 18 is vertically mounted on the frame 1, and the horizontal rod 19 is vertically mounted on top of the vertical rod 18. The end of the horizontal rod 19 is used to contact the end face of the air filter 7 to limit the movement of the air filter 7. In other embodiments, the end limiting assembly 17 can also be an L-shaped rod that extends to the end of the air filter 7 to form a limit.

[0043] Preferably, the vertical rod 18 is slidably connected to the frame 1, and the horizontal rod 19 is slidably connected to the vertical rod 18.

A fastening nut is slidably installed in the groove 9, and a fastening screw 11 is movably inserted into the frame 1. The fastening screw 11 passes through the frame 1, the groove 9, and is threadedly connected to the fastening nut. Both the vertical rod 18 and the horizontal rod 19 are slidably installed and locked by the fastening screw 11. In practical applications, the height of the vertical rod 18 and the extension length of the horizontal rod 19 can be adjusted to ensure that the horizontal rod 19 can contact the end face of the air filter 7 to form a limit, so as to be suitable for the positioning of different air filters 7.

[0044] Preferably, the positioning plate 2 is also provided with a model code 20, and each positioning plate 2 is provided with a different model code 20 to facilitate identification by staff.

[0045] Preferably, a side limiting component 21 for positioning the side of the air filter 7 is also provided on the frame 1 on one side of the positioning plate 2 to prevent the air filter 7 from rotating during assembly and further improve the assembly accuracy. The structure of the side limiting component 21 is the same as that of the end limiting component 17, that is, the side limiting component 21 also includes a vertical rod 18 and a horizontal rod 19. The side limiting component 21 contacts the outer wall of the air filter 7 to form a positioning. At the same time, the vertical rod 18 and the horizontal rod 19 are also slidingly installed structures and are locked by fastening screws 11. In practical applications, the height of the vertical rod 18 and the extension length of the horizontal rod 19 can be adjusted to ensure that the horizontal rod 19 can contact the side of the air filter 7 to form a limit, so as to be suitable for the positioning of different air filters 7.

[0046] An air filter assembly mounting bracket assembly method according to this embodiment includes the following steps:

[0047] S1: Adjust the relative positions of the multiple support seats 3, then place the positioning plate 2 on top of the multiple support seats 3, use the multiple support seats 3 to support the four corners of the bottom of the positioning plate 2, and then fasten the positioning plate 2 to the frame 1. Specifically, after the positioning plate 2 is placed, move the fastening screw 11 along the opening slot 10 of the positioning plate 2 so that the fastening screw 11 is inserted into the opening slot 10, and finally tighten the fastening screw 11 to achieve the fastening of the positioning plate 2.

[0048] S2: Adjust the distance between the end face of the end limiting component 17 and the positioning component to the distance between the mounting bracket 6 and the end face of the air filter 7. Specifically, adjust the horizontal rod 19 of the end limiting component 17 to move horizontally so that the distance between the end face of the horizontal rod 19 and the center of the positioning post 14 of the positioning component is equal to the distance between the mounting bracket 6 and the end face of the air filter 7.

[0049] S3: Position the two mounting brackets 6 on the positioning plate 2 using the positioning assembly, and determine the relative distance between the two mounting brackets 6. Specifically, align the two bolt holes of the mounting bracket 6 with the two positioning posts of the pair of positioning posts 14 of the positioning assembly, and then lower the mounting bracket 6 onto the positioning plate 2.

[0050] S4: The two mounting brackets 6 are pressed onto the positioning plate 2 using the clamping assembly to achieve the fastening of the mounting brackets 6. Specifically, multiple corner cylinders 15 are activated to work simultaneously. The corner cylinders 15 rotate towards one side of the mounting bracket 6, driving the pressure block 16 to rotate and press down to press and fix the mounting bracket 6.

[0051] S5: Place the air filter 7 into the two mounting brackets 6 and make the end of the air filter 7 fit tightly against the end face of the end limiting component 17 to determine the axial position of the two mounting brackets 6 relative to the air filter 7.

[0052] S6: Tighten the locking nut corresponding to the mounting bracket 6 with a wrench to fix the mounting bracket 6 on the air filter 7, thus completing the assembly of the air filter assembly mounting bracket.

[0053] In step S5, after the air filter 7 is placed, the horizontal rod 19 of the side limiting assembly 21 is adjusted so that its end face contacts the outer wall of the air filter 7 to form a limit, allowing the air filter 7 to rotate and further improving the assembly accuracy.

[0054] Example 2

[0055] See Figures 5-7 This is another specific embodiment of the present invention. This embodiment is basically the same as embodiment 1, except that a lifting assembly 22 for lifting the assembled air filter assembly is provided on the frame 1 on both sides of the positioning plate 2. The lifting assembly 22 includes an electric push rod 23, a U-shaped frame 24 and a roller 25. The electric push rod 23 is fixedly connected to the frame 1 through a support frame 26. The height of the electric push rod 23 is below the horizontal symmetry plane of the air filter 7 and above the positioning plate 2, ensuring that the air filter 7 can be lifted when the roller 25 pushes the air filter 7. The closed end of the U-shaped frame 24 is connected to the output end of the electric push rod 23. Both ends of the roller 25 are rotatably connected to the open end of the U-shaped frame 24. The air filter assembly is lifted by using the rotatable roller 25, which reduces the friction between the roller 25 and the air filter 7, thereby protecting the air filter 7.

[0056] An air filter assembly mounting bracket assembly method according to this embodiment includes the following steps:

[0057] S1: Adjust the relative positions of the multiple support seats 3, then place the positioning plate 2 on top of the multiple support seats 3, use the multiple support seats 3 to support the four corners of the bottom of the positioning plate 2, and then fasten the positioning plate 2 to the frame 1. Specifically, after the positioning plate 2 is placed, move the fastening screw 11 along the opening slot 10 of the positioning plate 2 so that the fastening screw 11 is inserted into the opening slot 10, and finally tighten the fastening screw 11 to achieve the fastening of the positioning plate 2.

[0058] S2: Adjust the distance between the end face of the end limiting component 17 and the positioning component to the distance between the mounting bracket 6 and the end face of the air filter 7. Specifically, adjust the horizontal rod 19 of the end limiting component 17 to move horizontally so that the distance between the end face of the horizontal rod 19 and the center of the positioning post 14 of the positioning component is equal to the distance between the mounting bracket 6 and the end face of the air filter 7.

[0059] S3: Position the two mounting brackets 6 on the positioning plate 2 using the positioning assembly, and determine the relative distance between the two mounting brackets 6. Specifically, align the two bolt holes of the mounting bracket 6 with the two positioning posts of the pair of positioning posts 14 of the positioning assembly, and then lower the mounting bracket 6 onto the positioning plate 2.

[0060] S4: The two mounting brackets 6 are pressed onto the positioning plate 2 using the clamping assembly to achieve the fastening of the mounting brackets 6. Specifically, multiple corner cylinders 15 are activated to work simultaneously. The corner cylinders 15 rotate towards one side of the mounting bracket 6, driving the pressure block 16 to rotate and press down to press and fix the mounting bracket 6.

[0061] S5: Place the air filter 7 into the two mounting brackets 6 and make the end of the air filter 7 fit tightly against the end face of the end limiting component 17 to determine the axial position of the two mounting brackets 6 relative to the air filter 7.

[0062] S6: Tighten the locking nut corresponding to the mounting bracket 6 with a wrench to fix the mounting bracket 6 on the air filter 7, and complete the assembly of the air filter assembly mounting bracket;

[0063] S7: Multiple corner cylinders 15 reset simultaneously, then the electric push rod 23 is activated, driving the roller 25 to move towards the air filter 7 until the roller 25 contacts the air filter 7. The roller 25 continues to move and rotates on its own, lifting the air filter 7, so that the staff can remove the air unit.

[0064] In this embodiment, after the air filter assembly mounting bracket is assembled, the lifting component 22 can be used to lift the air filter 7, so that the mounting bracket 6 is detached from the positioning component. This makes it easier for workers to remove the air filter assembly and avoids the problem of the mounting bracket 6 being displaced by the impact of the positioning column 14 when workers directly pull the air filter 7, thus further ensuring the assembly accuracy.

[0065] Preferably, both ends of the roller 25 are provided with rotating shafts 27, which are rotatably connected to the U-shaped frame 24 via bearings. Both the rotating shafts 27 and the roller 25 are hollow structures and are connected to each other. One of the rotating shafts 27 passes through the U-shaped frame 24 and is connected to an air inlet pipe 28 via a sealed bearing. The air inlet pipe 28 is connected to the rotating shaft 27 and to an air pump. Multiple air jet holes 29 are provided on the outer wall of the roller 25. During the lifting of the air filter 7, the air pump injects high-pressure gas into the roller 25 through the air inlet pipe 28 and the rotating shaft 27. The high-pressure gas is then ejected through the air jet holes 29 to blow away impurities and dust from the surface of the air filter and the positioning plate 2, so as not to affect the assembly accuracy. It also facilitates the separation of the roller 25 from the air filter 7, further facilitating the removal of the air filter assembly.

[0066] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of the present invention, and these will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
