Description

Technical Field

[0001] The utility model belongs to the field of mechanical equipment maintenance, and particularly relates to a disassembly and assembly tool for an adjustable air compressor filter element. Background Technique

[0002] In industrial production, compressed air, as an important power source and process medium, its purity directly affects production efficiency and product quality. AtlasCopco, as a well-known air compressor manufacturer, its supporting compressed air filters play a key role in ensuring the quality of compressed air. These filters effectively remove impurities such as moisture, oil mist, and dust in compressed air through precision filter elements built-in, ensuring that the compressed air supplied to the production line meets high-standard requirements.

[0003] However, limited by actual production conditions, there are significant deficiencies and challenges in the process of replacing the filter element. First of all, limited by the space conditions of the equipment installation environment, especially for those industrial sites with compact spaces, the traditional method of replacing the filter element often relies on manual operation. Due to the lack of special disassembly and installation tools, operators have to rely on their hands to tighten or loosen the filter element. This method not only has a large labor intensity but also low efficiency; more seriously, in a limited space, it is difficult to ensure uniform force application by hand, which easily causes components such as positioning rods to be deformed or even damaged under non-uniform stress, thereby affecting the overall performance of the filter and the safety of the equipment.

[0004] Secondly, replacing the filter element by hand also brings the risk of damage to the filter element itself. As the core component of the filter, the surface and internal structure of the filter element are crucial for the filtering effect. In the absence of professional tool assistance, the functional parts of the filter element are likely to come into contact with the operator's hands or other non-professional tools during the installation process, resulting in scratches, depressions on the surface of the filter element or damage to the internal structure, thus significantly reducing the filtering efficiency and service life and affecting the final quality of compressed air.

[0005] Therefore, in summary, how to provide a special disassembly and assembly tool for the air compressor filter element to solve the problems such as potential safety hazards, low efficiency, and easy damage of the filter element during manual operation, so as to improve production efficiency and reduce maintenance costs is a technical problem urgently to be solved in this field.

[0007] To solve the above problems and achieve the above objectives, the utility model adopts the following technical solutions:

[0008] An adjustable disassembly and assembly tool for the air compressor filter element, comprising:

[0009] A handle (1), the handle (1) being a cylindrical rod-shaped structure;

[0010] A connecting rod (2), one end of the connecting rod (2) being connected to the handle (1) and the other end being connected to a workbench (3);

[0011] A workbench (3), the workbench (3) being an overall cylindrical structure;

[0012] Fixed teeth (4), the fixed teeth (4) being fixedly connected below the workbench (3);

[0013] A worm gear mechanism (5), the worm gear mechanism (5) being detachably connected to the workbench (3);

[0014] A movable tooth mechanism (6), the movable tooth mechanism (6) being an overall "T"-shaped structure, and the movable tooth mechanism (6) being detachably connected to the workbench (3).

[0015] As a preferred solution of the present utility model, on the workbench (3):

[0016] There is a worm gear groove (31), the worm gear groove (31) being a rectangular structure with two central holes on the inner side, corresponding one by one to the locking part (33);

[0017] There is a sliding groove (32), the bottom of the sliding groove (32) being rectangular, and the side surface penetrating through one end of the workbench (3) opposite to the fixed teeth (4) to open a hole, the shape of the hole corresponding one by one to the movable tooth mechanism (6);

[0018] There is a locking part (33), the locking part (33) being located above the sliding groove (32), being a hollow cylinder with internal threads.

[0019] As a preferred solution of the present utility model, the fixed teeth (4) are an overall cylindrical structure, and the inner side surface is a serrated structure.

[0020] As a preferred solution of the present utility model, the worm gear mechanism (5) comprises:

[0021] A worm gear shaft (51), the worm gear shaft (51) being an overall cylindrical structure, one end having threads, and the threaded end having a "slotted crosshead", and the worm gear shaft (51) sequentially passing through the locking part (33), the worm gear (52) and the central hole in the worm gear groove (31), and being detachably connected to the workbench (3);

[0022] A worm gear (52), the thread profile of the worm gear (52) is arc-shaped, and there is an inclined angle at the top. The worm gear (52) is detachably connected to the workbench (3) through a worm shaft (51) and can rotate around the worm shaft (51).

[0023] As a preferred embodiment of the present invention, the movable tooth mechanism (6) includes:

[0024] A worm (61), the worm (61) is a cylindrical structure as a whole, and there is a tooth part at the upper end;

[0025] A movable tooth (62), the movable tooth (62) is fixedly connected to the lower part of the worm (61) through a circular rod.

[0026] As a preferred embodiment of the present invention, the movable tooth mechanism (6) is installed through the opening of the chute (32). The tooth part of the movable tooth (62) meshes with the worm gear (52) and can move in the chute (32). When the worm gear (52) is rotated, the worm gear (52) can drive the movable tooth mechanism (6) to move towards or away from the fixed tooth (4).

[0027] The working principle of the present invention is as follows: The overall structure of the disassembly and assembly tool provides an operating torque through the handle (1), and the connecting rod (2) transmits the torque to the workbench (3) to ensure the stability of the whole tool during operation. The workbench (3) is the core component, integrating key structures such as a worm gear groove (31), a chute (32) and a locking part (33), providing a basis for the installation and function realization of the worm gear mechanism (5) and the movable tooth mechanism (6).

[0028] When disassembling the filter element (72), put the fixed tooth (4) of the disassembly and assembly tool into one of the holes of the filter element (72) of the filter (7), and rotate the worm gear (52). Due to the meshing action between the worm gear (52) and the worm (61), the rotation of the worm gear (52) will drive the worm (61) and the connected movable tooth (62) to move along the chute (32) towards the fixed tooth (4). When moving to an appropriate distance, put the movable tooth (62) into the hole of the other symmetrically arranged filter element (72); further, continue to rotate the worm gear (52). As the movable tooth (62) approaches, the serrated structure of its tooth part and the serrated structure of the fixed tooth (4) form a clamping force to firmly clamp the filter element (72); at this time, the operator can rotate the handle (1), and through the self-locking characteristic of the worm and worm gear and the clamping force of the fixed tooth (4) and the movable tooth mechanism (6), easily loosen and remove the filter element; after moving the filter element (72) to the designated placement position, rotate the worm gear (52) in the reverse direction to make the movable tooth mechanism (6) move away from the fixed tooth (4), and release the filter element (72) to complete the disassembly process.

[0029] When installing the filter element (72), the operator first places the filter element (72) on the positioning rod in the specified groove of the filter (7), puts the fixed teeth (4) of the disassembly and assembly tool into one of the holes of the filter element (72) of the filter (7), and rotates the worm gear (52). Due to the meshing of the worm gear (52) and the worm (61), the rotation of the worm gear (52) will drive the worm (61) and the connected movable teeth (62) to move along the chute (32) towards the direction of the fixed teeth (4). When moving to an appropriate distance, the movable teeth (62) are placed into the hole of the other symmetrically arranged filter element (72); continue to rotate the worm gear (52). As the movable teeth (62) approach, the serrated structure of its tooth part and the serrated structure of the fixed teeth (4) form a clamping force to firmly clamp the filter element (72); further, rotate the handle (1) to screw the filter element tightly until it is installed in place, and then rotate the worm gear (52) in the reverse direction to make the movable tooth mechanism (6) move away from the fixed teeth (4), release the filter element, and complete the installation.

[0064] Further, as Figure 4 shown, the movable tooth mechanism 6 is installed through the opening of the chute 32.

When the worm gear 52 rotates, the worm gear 52 can drive the movable tooth mechanism 6 to move towards or away from the fixed tooth 4.

[0065] In summary, a more specific embodiment of the present invention is as follows:

[0066] First, the worm gear shaft 51 is sequentially installed through the central holes of the locking part 33, the worm gear 52, and the worm gear groove 31. Then, the "slotted" part on the worm gear shaft 51 is rotated by a screwdriver, and the worm gear 52 is fixed in the worm gear groove 31 of the workbench 3 by using the threaded worm gear shaft 51 to ensure that it can rotate smoothly. Subsequently, the movable tooth mechanism 6 is installed through the opening of the chute 32, so that the tooth part of the movable tooth mechanism 6 meshes with the arc-shaped thread profile of the worm gear 52, completing the assembly of the tool. At this time, the movable tooth mechanism 6 can move freely within the chute 32, but is restricted by the worm gear and worm drive mechanism.

[0067] When disassembling the filter element 72, the fixed tooth 4 of the disassembly and assembly tool is placed into one of the holes of the filter element 72 of the filter 7. The worm gear 52 is rotated. Due to the meshing effect between the worm gear 52 and the worm 61, the rotation of the worm gear 52 will drive the worm 61 and the connected movable tooth 62 to move along the chute 32 towards the fixed tooth 4. When moving to an appropriate distance, the movable tooth 62 is placed into the hole of the other symmetrically arranged filter element 72. Further, the worm gear 52 is continuously rotated. As the movable tooth 62 approaches, the serrated structure of its tooth part and the serrated structure of the fixed tooth 4 form a clamping force to firmly clamp the filter element 72. At this time, the operator can rotate the handle 1, and through the self-locking characteristic of the worm gear and worm and the clamping force of the fixed tooth 4 and the movable tooth mechanism 6, the filter element can be easily loosened and removed. After moving the filter element 72 to the designated placement position, the worm gear 52 is rotated in the reverse direction to move the movable tooth mechanism 6 away from the fixed tooth 4, releasing the filter element 72 to complete the disassembly process.

[0068] When installing the filter element 72, the operator first places the filter element 72 on the positioning rod in the designated slot of the filter 7. The fixed tooth 4 of the disassembly and assembly tool is placed into one of the holes of the filter element 72 of the filter 7. The worm gear 52 is rotated. Due to the meshing effect between the worm gear 52 and the worm 61, the rotation of the worm gear 52 will drive the worm 61 and the connected movable tooth 62 to move along the chute 32 towards the fixed tooth 4. When moving to an appropriate distance, the movable tooth 62 is placed into the hole of the other symmetrically arranged filter element 72. The worm gear 52 is continuously rotated. As the movable tooth 62 approaches, the serrated structure of its tooth part and the serrated structure of the fixed tooth 4 form a clamping force to firmly clamp the filter element 72. Further, the handle 1 is rotated to screw the filter element tightly until it is installed in place. Subsequently, the worm gear 52 is rotated in the reverse direction to move the movable tooth mechanism 6 away from the fixed tooth 4, releasing the filter element to complete the installation.
