[0012] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0013] like Figures 1 to 4 As shown in the figure, the filter auxiliary fixing and installation mechanism provided in this embodiment of the utility model includes a workpiece 1, a fixing mechanism 2 and a height adjustment mechanism 3; In one specific embodiment, the workpiece 1 is a cylindrical filter, the fixing mechanism 2 is the core clamping component, located at the top of the entire mechanism, directly contacting and clamping the workpiece 1; the height adjustment mechanism 3 is located below the fixing mechanism 2, providing it with vertical support and adjusting its overall height. In a specific embodiment, to reduce the shaking of workpiece 1 and implement fixed clamping, this utility model is provided with a fixing mechanism 2. The fixing mechanism 2 includes a drive rod 4, a transmission disk 5, a jaw 6, a disk body 7, a sealing disk 8, and a bolt 9. The disk body 7 is the basic frame of the fixing mechanism 2, and is a disc-shaped structure with a through hole in the center for workpiece 1 to pass through. Multiple radially evenly distributed guide rails 11 are machined on the end face of the disk body 7. The jaw 6 is installed by a slider at its bottom engaging with the guide rails 11 on the disk body 7, so that each jaw 6 can slide independently radially along the guide rail 11. The transmission disk 5 is rotatably disposed inside the disk body 7. An Archimedean spiral groove is machined on the side near the jaw 6, and circular involute gear teeth are machined on the other side. The tail of the jaw 6 engages with the Archimedean spiral groove through a connecting member, which is a bolt 9 or a pin. The disk body 7 has openings... The drive rod 4 passes through the drive hole 10. One end of the drive rod 4 is provided with a helical gear that meshes with the gear teeth on the back of the transmission disk 5. The sealing disk 8 is fixedly connected to the disk body 7 by bolts 9, which serves to seal and prevent dust and protect the internal mechanism. The jaws 6 are also provided with jaws 12 that directly contact the workpiece 1. By changing the jaws 12 of different shapes, the contact surface and friction with the workpiece 1 can be further increased, which can effectively protect the surface of the workpiece 1 and provide a stronger clamping force. When the operator rotates the drive rod 4, the drive rod 4 meshes with the gear teeth on the back of the transmission disk 5 through the gear at its end, which drives the transmission disk 5 to rotate. When the Archimedean spiral groove on the front of the transmission disk 5 rotates, it uses its special spiral characteristics to push the jaws 6 that cooperate with it, thereby forcing all the jaws 6 to move synchronously and equidistantly towards the center or outward along the guide rail 11 to clamp filters of different diameters. In one specific embodiment, to adjust the working height of the fixing mechanism 2, this utility model provides a height adjustment mechanism 3. The height adjustment mechanism 3 includes a support block 13, telescopic legs 14, a gear mechanism 15, and an adjustment switch 16. The support block 13 is fixedly connected to the disk 7 of the fixing mechanism 2 above, serving as a base for height adjustment. Two telescopic legs 14 are installed on the surface of the support block 13 away from the fixing mechanism 2. The telescopic legs 14 are movably connected to the support block 13, and their height is adjusted through the internal gear mechanism 15. The two telescopic legs 14 are connected to the gears in the gear mechanism 15 via a rotating shaft 17. An adjustment switch 16 is fixedly connected to the outside of one end of the rotating shaft 17 and the telescopic leg 14. Rotating the adjustment switch 16 drives the entire gear mechanism 15 to move. The adjustment switch 16 includes a rotating shaft 17, a gear mechanism 18, and a braking mechanism. The braking mechanism includes a brake pawl 19 and a brake gear 20. The driven wheel in the gear mechanism 18 is coaxially connected to the gear in the gear tooth mechanism 15 via the rotating shaft 17, and the driving wheel in the gear mechanism 18 is coaxially connected to the brake gear 20. The brake pawl 19 and the brake gear 20 can mesh. When the height needs to be adjusted, the operator rotates the adjustment switch 16. Through the transmission of the rotating shaft 17 and the gear mechanism 18, the gear tooth mechanism 15 is driven to move, thereby synchronously controlling all telescopic legs 14 to extend or retract, achieving smooth lifting and lowering of the entire mechanism. When the desired height is reached, the brake pawl 19 engages with the tooth groove of the brake gear 20 under the action of a spring, effectively preventing the telescopic legs 14 from accidentally retracting under the weight of the equipment or external force, ensuring the stability of the working height. The working process of this utility model is as follows: The working process of a filter auxiliary fixing installation mechanism is divided into a clamping and fixing stage, a height adjustment stage, and a locking completion stage; Clamping and fixing stage: After placing the workpiece 1, the operator starts to rotate the drive rod 4. The helical gear at the end of the drive rod 4 rotates accordingly, and drives the involute gear teeth on the back of the transmission disk 5 that meshes with it, so that the transmission disk 5 rotates in the disk body 7. During the rotation, the Archimedean spiral groove on the front of the transmission disk 5 pushes the connecting part at the tail of the chuck 6 that it cooperates with, forcing all the chucks 6 to overcome the friction and slide synchronously and smoothly towards the center along the radially distributed guide rails 11 on the disk body 7. Finally, the jaws 12 on all the chucks 6 together hold the outer wall of the workpiece 1, completing the radial and firm clamping. Height adjustment stage: After radial clamping is completed, the operator rotates the adjustment switch 16 of the height adjustment mechanism 3. Power is transmitted to the gear mechanism 18 through the rotating shaft 17, which drives the gear tooth mechanism 15 connected to it to move. This precisely controls the two telescopic legs 14 to extend or retract synchronously, thereby smoothly lifting or lowering the entire fixing mechanism 2 and the workpiece 1 it holds until the precise installation height is reached. Locking completion stage: After the workpiece 1 is adjusted to the predetermined height, the operator quickly engages the brake pawl 19 into the tooth groove of the brake gear 20 to form a mechanical self-lock, which effectively prevents the telescopic leg 14 from retracting unexpectedly under the weight of the equipment or external vibration. The above-disclosed embodiments are merely specific examples of this utility model. However, the embodiments of this utility model are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
