Description

Technical Field

[0001] This application relates to the field of mechanical assembly tool technology, and in particular to an online convenient cylinder tightening tool. Background Technology

[0002] In the field of mechanical assembly, cylindrical workpieces are often assembled with matching filter head workpieces via threaded connections. In such assembly scenarios, the main workpiece is the cylindrical body, and the separate workpiece is the filter head. The cylindrical body needs to be precisely and without damage screwed onto the filter head. Since ordinary pipe wrenches cannot meet the operational requirements of cylindrical bodies with large diameters, tooling is often used to complete the installation of the cylindrical body and filter head.

[0003] The original tightening process involved the operator placing a tooling strap on the cylinder, locking it with a buckle, and then manually pulling the strap to lock the cylinder in place. This process was inconvenient, and the process of putting on the tooling strap and locking the buckle was time-consuming, severely impacting assembly efficiency. Furthermore, this operation required the operator to apply significant pulling force continuously, resulting in high labor intensity and manpower consumption. Additionally, since both the cylinder and the filter head were made of aluminum, a relatively soft material, the workpieces were easily damaged, and the manual force was difficult to control precisely, easily leading to biting or crushing, causing damage to the workpiece surface or threads.

[0004] Some tightening processes involve directly fitting a clamp-like tightening tool onto the cylinder and locking it in place. Then, a power tool is used to drive the clamp-like tightening tool to rotate, which in turn rotates the cylinder to install the filter head. While this process reduces labor costs and improves assembly efficiency to some extent, the large contact area between the clamp-like tightening tool and the cylinder increases the likelihood of damage to the cylinder's surface. Summary of the Invention

[0005] In order to achieve efficient tightening and assembly of the cylinder and filter head, and to reduce the damage to the cylinder caused by the tightening tool, this application provides an online convenient cylinder tightening tool.

[0006] The online convenient cylinder tightening tool provided in this application adopts the following technical solution: An online convenient cylinder tightening tool includes a flipping component, on which a driven wheel and a drive wheel are connected. At least two driven wheels are provided. The flipping component can flip to make the drive wheel and the driven wheel abut against the cylinder. When the centers of the drive wheel and all the driven wheels are concentric, the drive wheel and all the driven wheels together clamp the cylinder. The drive wheel is connected to a drive component, which is used to connect to a power tool and drive the drive wheel to rotate through the power tool. The driven wheel rotates under the drive of the drive wheel, so that the drive wheel and the driven wheel together drive the cylinder to rotate.

[0007] By adopting the above technical solution, the centers of the drive wheel and at least two driven wheels are concentric, realizing multi-point clamping of the cylinder. Compared with traditional clamping tools, the contact area with the cylinder is greatly reduced, fundamentally reducing the risk of pressure and scratches on the surface of the aluminum cylinder. At the same time, with the help of power tools, the drive wheel is driven to rotate through the drive component, and the driven wheels rotate synchronously with the cylinder. The speed and torque are precisely controlled by the power tools, significantly improving assembly efficiency.

[0008] Optionally, the flipping component includes a first clamp and a second clamp, one end of the first clamp and the second clamp are hinged together, and the other end of the first clamp and the second clamp are detachably connected; There are two driven wheels, both of which are rotatably connected to the second clamp, and the drive wheel is rotatably connected to the first clamp.

[0009] By adopting the above technical solution, the first clamp and the second clamp adopt a flip structure with one end hinged and the other end detachably connected. During installation, the clamp can be opened first and then fastened to tighten the cylinder, avoiding the damage caused by hard friction between the traditional tool and the cylinder when directly applied, and greatly reducing the possibility of scratching the cylinder. The two driven wheels and one drive wheel form a three-point clamping support structure, which ensures the coaxiality and stability of the cylinder when clamping it, while using the fewest rollers to simplify the structure. The three-point positioning principle is used to prevent the cylinder from shifting during the rotation and tightening process, further ensuring the assembly accuracy.

[0010] Optionally, the first clamp has a first receiving groove, the second clamp has a second receiving groove, the drive wheel is located in the first receiving groove, and the driven wheel is located in the second receiving groove.

[0011] By adopting the above technical solution, the first receiving groove of the first clamp and the second receiving groove of the second clamp not only provide precise installation space for the drive wheel and the driven wheel, ensuring that the wheel does not interfere with the clamp body when rotating, but also reduce the redundant material of the clamp without weakening the structural strength of the clamp and ensuring the overall stability of the device, thus achieving a lightweight design of the tool.

[0012] Optionally, the driving component includes a first drive shaft, one end of which has a connecting groove for connecting to a power tool. A first bevel gear is bolted to the end of the first drive shaft away from the connecting groove, and the first bevel gear and the first drive shaft are coaxially fixed. A second bevel gear is coaxially fixed to the drive wheel, and the first bevel gear meshes with the second bevel gear.

[0013] By adopting the above technical solution, the meshing of the first bevel gear and the second bevel gear achieves a 90° turn in the driving direction, converting the axial power of the first drive shaft into the radial rotational power of the drive wheel. This allows the power tool connection end to face the operator's front, avoiding a conflict between the tool's direction and the operator's line of sight. The operator can work conveniently without adjusting their stance, reducing the difficulty of operation. At the same time, the bevel gear transmission has high precision and low power loss, ensuring stable drive wheel speed and further guaranteeing the smoothness of the cylinder tightening process.

[0014] Optionally, the first clamp is connected to a mounting shell, a first bearing is provided inside the mounting shell, the first drive shaft passes through the first bearing, and a first fixing sleeve is rotatably connected to the end of the first drive shaft away from the first bevel gear, and the first fixing sleeve is fixedly connected to the mounting shell. The first clamp is provided with a second bearing. The second bearing and the drive wheel are connected together by a second drive shaft. One end of the second drive shaft is coaxially bolted to a second bevel gear. The end of the second drive shaft away from the second bevel gear is rotatably connected to a second fixing sleeve. The second fixing sleeve is fixedly connected to the first clamp.

[0015] By adopting the above technical solution, the first fixed sleeve inside the housing cooperates with the first bevel gear to radially and axially position the first drive shaft; the second bearing inside the first clamp cooperates with the second fixed sleeve to double fix the second drive shaft, which not only prevents the drive shaft from slipping or shaking when rotating at high speed, ensuring the accuracy of bevel gear meshing, avoiding transmission jamming or wear of parts caused by shaft misalignment, but also reduces friction between the shaft and the fixed structure, extending the tool's service life. At the same time, this connection method facilitates the disassembly and maintenance of bearings, drive shafts and other parts in the later stage.

[0016] Optionally, a base is included, the height of which is higher than the height of the filter head, so that the cylinder can be inserted into the base. A through groove is provided in the base, the through groove is in the shape of annular steps, and the inner diameter of the upper step surface of the through groove is smaller than the inner diameter of the lower step surface of the through groove.

[0017] By adopting the above technical solution, the height of the base is higher than that of the filter head, allowing the cylinder to be smoothly inserted into the base; the lower stepped surface of the annular stepped groove has a larger inner diameter, which can initially accommodate and position the filter head, preventing the filter head from shifting during assembly; the upper stepped surface has a smaller inner diameter, which can accurately guide and limit the lower part of the cylinder, ensuring that the cylinder and the filter head remain coaxial in the initial stage of assembly, reducing the difficulty of thread connection or thread damage caused by misalignment, and laying the foundation for subsequent precise tightening and positioning.

[0018] Optionally, the top of the base is provided with a first support rod and a second support rod. There are two first support rods, and the two first support rods are fixedly connected to the base. The end of the first support rod away from the base is fixedly connected to the first clamp. A limiting support is provided on the base, and the second support rod is hinged to the limiting support. The limiting support is used to restrict the second support rod from rotating in the direction of the axis closer to the base. A limiting groove is opened at the bottom of the second clamp, and the end of the second support rod away from the base abuts in the limiting groove. The limiting groove is used to restrict the second support rod from rotating in the direction of the axis away from the base, so that the second support rod is always in a vertical state during operation, thus supporting the second clamp.

[0019] By adopting the above technical solution, the two fixedly connected first support rods provide stable vertical support for the first clamp, preventing the first clamp from tilting due to force during operation; the second support rod is hinged to the limiting support, and can be flipped away from the axis of the base when the second clamp is opened and closed, providing installation clearance space for the second clamp and avoiding obstruction of clamp fastening; during operation, the end of the second support rod away from the base abuts against the limiting groove of the second clamp, and the limiting support and the limiting groove together limit the second support rod, so that the second support rod always remains in a vertical state, providing stable support for the second clamp, ensuring that the entire flipping component is structurally stable when clamping the cylinder to rotate, and avoiding damage to the cylinder due to uneven force caused by clamp displacement.

[0020] Optionally, a fixing rod is included, with a first fixing plate fixedly connected to the bottom of the fixing rod. A plurality of first sliding pieces are slidably disposed on the first fixing plate, and a first guide post is disposed on the first sliding piece. A first rotating sleeve is sleeved on the fixing rod, and a first rotating disk and a second fixing disk are fixedly connected to the first rotating sleeve. A plurality of first arc-shaped grooves are formed on the first rotating disk. The first rotating disk is located below the second fixing disk, and the first fixing disk is located below the first rotating disk. The first guide post passes through the first arc-shaped grooves, so that when the first rotating disk rotates, it can drive the first sliding piece to extend out of the first fixing disk. A second rotating sleeve is fitted onto the first rotating sleeve, and a second rotating disk is fixedly connected to the second rotating sleeve. A plurality of second sliding pieces are slidably arranged on the second rotating disk, and a second guide post is provided on the second sliding piece. A plurality of second arc-shaped grooves are opened on the second rotating disk. The second fixed disk is located above the second rotating disk, and the second guide post passes through the second arc-shaped groove, so that when the second rotating disk rotates, it can drive the second sliding piece to extend out of the second fixed disk.

[0021] By adopting the above technical solution, rotating the first rotating sleeve drives the first rotating disk to rotate. Through the cooperation of the first arc-shaped groove and the first guide post, the first sliding plate is driven to extend from the first fixed disk and abut against the inner wall of the filter head. Rotating the second rotating sleeve drives the second rotating disk to rotate. Through the cooperation of the second arc-shaped groove and the second guide post, the second sliding plate is driven to extend from the second fixed disk and abut against the inner wall of the cylinder. The cooperation of the two can correct the axis of the filter head and the cylinder, ensuring that the two are completely concentric. This avoids the problems of thread seizing and workpiece damage caused by insufficient concentricity from the root, and further improves the assembly accuracy and pass rate.

[0022] Optionally, the drive wheel, the driven wheel, and the end of the slide away from the fixed rod are all coated with rubber.

[0023] By adopting the above technical solution, when the drive wheel, driven wheel, and sliding vane come into contact with the aluminum cylinder and filter head, hard collisions and scratches between metals can be avoided, effectively protecting the integrity of the workpiece surface; at the same time, the rubber coating can increase the coefficient of friction between the drive wheel and driven wheel and the cylinder, ensuring that the drive wheel can stably drive the cylinder to rotate when it rotates, avoiding slippage, and taking into account both protection and transmission stability.

[0024] Optionally, the driving wheel and the driven wheel are of the same size, and the ratio of the diameter of the driving wheel and the driven wheel to the diameter of the cylinder is 4:1.

[0025] By adopting the above technical solution, the drive wheel and driven wheel are designed to be the same size, ensuring that they rotate synchronously when driving the cylinder. The diameter ratio of the drive wheel, driven wheel and cylinder is 4:1. This ratio setting can realize speed reduction transmission, converting the high speed of the power tool into the low speed and high torque required for cylinder tightening. This can not only meet the tightening torque requirements of the threaded connection between the cylinder and the filter head, but also avoid over-tightening or thread stripping caused by excessive speed, thus improving the controllability and reliability of the tightening process.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. By forming a multi-point clamping structure with the drive wheel and at least two driven wheels concentrically, the contact area with the aluminum cylinder is significantly reduced, avoiding surface damage caused by the large-area contact of traditional clamps; at the same time, the rubber-coated design of the drive wheel, driven wheels and sliding vane ends can isolate direct metal contact and prevent scratches on the cylinder; in addition, the concentricity correction function of the fixing rod and sliding vane can force the filter head to be aligned with the cylinder axis, fundamentally avoiding the thread seizing problem caused by insufficient concentricity, protecting the integrity of the workpiece in all aspects, and realizing non-destructive assembly of the workpiece; 2. By using power tools to drive the wheel to rotate via a drive component, the laborious operation of manually pulling the tooling belt is replaced. There is no need to spend time setting up the tooling belt and tightening the buckle, which significantly shortens the operation time. Moreover, power tools can precisely control the speed and torque, eliminating the need for operators to continuously apply pulling force. This reduces labor consumption and avoids assembly problems caused by uneven manual operation, further improving assembly efficiency and stability, and reducing labor intensity. 3. The three-point clamping and positioning of the drive wheel and two driven wheels ensures the coaxiality of the cylinder during clamping and prevents cylinder displacement during rotation and tightening. The stepped through groove of the base can perform preliminary positioning of the filter head and precise guidance of the cylinder, providing a coaxial foundation for initial assembly. With the cooperation of multiple structures, the difficulty of thread connection and the probability of damage are effectively reduced, the assembly qualification rate is greatly improved, and high assembly accuracy is guaranteed. 4. The flipping mechanism adopts a structure where the first and second clamps are hinged at one end and detachable at the other. During installation, the clamps can be opened first and then the cylinder can be fastened, avoiding the hard friction of directly fitting traditional tools, making operation more convenient. The bevel gear transmission enables 90° rotation of the drive direction, so that the connecting end of the power tool faces the operator, allowing operation without adjusting the stance. At the same time, the support rod provides stable support for the clamps, and the fixing sleeve and bearings position the drive shaft, ensuring that the tool does not slip or tilt during operation. The structure is stable and reliable, optimizing the tool's ease of operation and working stability.

[0027] 5. The first and second sliding vanes can be adjusted in length by rotating the sleeve to abut the filter head and the cylinder respectively, achieving concentricity between them; the equal-sized design of the drive wheel and driven wheel ensures synchronous transmission between the two, avoiding uneven force distribution on the cylinder due to differences in wheel diameter; and the 4:1 diameter ratio of the drive wheel, driven wheel and cylinder can convert the high speed of the power tool into low speed and high torque, which not only meets the tightening torque required for threaded connections, but also prevents over-tightening or thread stripping caused by excessive speed, ensuring that the tightening process is controllable and meets the standards, and enhancing tool compatibility and tightening controllability.

[0036] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0037] Example 1 This application discloses an online convenient cylinder tightening tool.

[0038] like Figures 1 to 3 An online convenient cylinder tightening tool includes a flipping component 1, which includes a first clamp 11 and a second clamp 12. One end of the first clamp 11 and the second clamp 12 are hinged to a hinge plate 14. The ends of the first clamp 11 and the second clamp 12 away from the hinge plate 14 are detachably connected. In this embodiment, the first clamp 11 and the second clamp 12 are connected by a wing nut 13.

[0039] The first clamp 11 has a first receiving groove 111, in which a drive wheel 21 is installed. The drive wheel 21 is rotatably connected to the first clamp 11. The second clamp 12 has two second receiving grooves 121, in which a driven wheel 22 is installed. The driven wheel 22 is rotatably connected to the second clamp 12. The circumference of the drive wheel 21 and the driven wheel 22 is coated with rubber, which protects the cylinder and increases the coefficient of friction between the drive wheel 21 and the driven wheel 22 and the cylinder, facilitating their synchronous rotation. The drive wheel 21 and the driven wheel 22 are of the same size, and the diameter ratio of the drive wheel 21 to the cylinder is 4:1, which realizes speed reduction transmission and avoids over-tightening or thread stripping caused by excessive speed.

[0040] When the second clamp 12 and the first clamp 11 are flipped and fixed by the wing nut 13, the centers of the three rollers, namely the drive wheel 21 and the two driven wheels 22, are concentric. The three rollers press against the cylinder together, achieving three-point clamping of the cylinder. While maintaining normal clamping function, the contact area with the cylinder is reduced, the wear of the tightening tool on the cylinder is reduced, and the cylinder is protected.

[0041] like Figure 4 The first clamp 11 is connected to the mounting shell 4. The first clamp 11 and the mounting shell 4 are both provided with a driving component 3. The driving component 3 is used to connect with the driving wheel 21 and drive the cylinder to rotate through the driving wheel 21 so that the cylinder is installed with the filter head.

[0042] The mounting housing 4 has a first receiving groove 111, and there are two first receiving grooves 111. Each first receiving groove 111 contains a first bearing 41. The first clamp 11 has a second receiving groove 121, and there are two second receiving grooves 121. Each second receiving groove 121 contains a second bearing 112. The drive component 3 includes a first drive shaft 31 and a second drive shaft 32. The first drive shaft 31 passes through all the first bearings 41. One end of the first drive shaft 31 has a connecting groove 311 for connecting with a power tool, so that the power tool drives the first drive shaft 31 to rotate. The end of the first drive shaft 31 away from the connecting groove 311 is bolted to a first bevel gear 33. The second drive shaft 32 passes through all the second bearings 112. The end of the second drive shaft 32 adjacent to the first bevel gear 33 is bolted to a second bevel gear 34. The first bevel gear 33 and the second bevel gear 34 mesh to transmit power. By driving the first drive shaft 31, the rotation of the drive wheel 21 can be controlled to drive the cylinder to rotate, realizing the efficient installation of the cylinder and the filter head, while also having a compact structure and transmission stability. The meshing transmission of the first bevel gear 33 and the second bevel gear 34 changes the driving direction of the power tool, allowing the operator to operate from the front to install the cylinder and filter head, thus improving the ease of operation.

[0043] A first fixing sleeve 42 is fixedly connected to the mounting housing 4. A first annular groove 312 is opened at one end of the first drive shaft 31 adjacent to the connecting groove 311. The first fixing sleeve 42 is disposed in the first annular groove 312, so that the first fixing sleeve 42 and the first drive shaft 31 are rotatably connected. The first fixing sleeve 42 is used to limit the first drive shaft 31 and prevent it from slipping. A second fixing sleeve 113 is fixedly connected to the first clamp 11. A second annular groove 321 is opened at one end of the second drive shaft 32 away from the second bevel gear 34. The second fixing sleeve 113 is disposed in the second annular groove 321, so that the second fixing sleeve 113 and the second drive shaft 32 are rotatably connected. The second fixing sleeve 113 is used to limit the second drive shaft 32 and prevent it from slipping.

[0044] The implementation principle of this application embodiment is as follows: open the first clamp 11 and the second clamp 12, put them on the cylinder, and lock them with the wing nut 13. At this time, the drive wheel 21 and the two driven wheels 22 jointly press against the cylinder to clamp the cylinder.

[0045] After aligning the power tool with the connecting slot 311, start the power tool. The torque is transmitted sequentially through the first drive shaft 31, the first bevel gear 33, the second bevel gear 34, and the second drive shaft 32 to the drive wheel 21. The drive wheel 21 drives the cylinder and the driven wheel 22 to rotate synchronously for installation.

[0046] The meshing transmission of the first bevel gear 33 and the second bevel gear 34 changes the direction of the first drive shaft 31, allowing the operator to use a power tool to connect to the connecting groove 311 from the front and drive the first drive shaft 31.

[0047] After installation, remove the power tool, open the wing nut 13, flip the first clamp 11 and the second clamp 12 open, and remove them from the cylinder to complete the installation.

[0048] The multi-point clamping structure formed by the drive wheel 21 and at least two driven wheels 22 with the same center significantly reduces the contact area with the aluminum cylinder, avoiding surface damage caused by the large-area contact of traditional clamps; at the same time, the rubber-coated design of the drive wheel 21 and driven wheels 22 can isolate direct metal contact and prevent scratches on the cylinder. By using a power tool to drive the drive wheel 21 to rotate via the drive component 3, the laborious operation of manually pulling the tooling belt is replaced. This eliminates the need to spend time setting up the tooling belt and tightening the buckle, significantly shortening the operation time. Furthermore, the power tool can precisely control the speed and torque, eliminating the need for operators to continuously apply pulling force. This reduces labor consumption and avoids assembly problems caused by uneven manual operation, further improving assembly efficiency and stability, thus increasing assembly efficiency and reducing labor intensity.

[0049] Example 2 The difference between this embodiment and Embodiment 1 is that, as Figure 5 and Figure 6 The system includes a base 5, which has a through groove 51 inside. Both the through groove 51 and the outer wall of the base 5 are stepped. The outer diameter of the upper stepped surface of the outer wall of the base 5 is smaller than the outer diameter of the lower stepped surface of the outer wall of the base 5. The inner diameter of the upper stepped surface of the through groove 51 is smaller than the inner diameter of the lower stepped surface of the through groove 51. This allows the base 5 to have better support while also providing initial fixation for the filter head and initial guidance for the cylinder, enabling the cylinder to be inserted into the base 5. This allows for initial calibration of the filter head and cylinder, facilitating the installation of the filter head and cylinder.

[0050] The base 5 is provided with a first support rod 52 and a second support rod 53. There are two first support rods 52. The two first support rods 52 and the second support rod 53 are all located on the top surface of the base 5 and are arranged at equal intervals along the top surface of the base 5. One end of the two first support rods 52 is fixedly connected to the top surface of the base 5, and the end of the first support rod 52 away from the base 5 is fixedly connected to the bottom surface of the first clamp 11. The base 5 is also fixedly connected to a limiting support 54. One end of the second support rod 53 is hinged to the limiting support 54. The limiting support 54 restricts the rotation angle of the second support rod 53, so that the end away from the limiting support 54 can only rotate 90° from a vertical position to the side away from the axis of the base 5. A limiting groove 122 is opened at the bottom of the second clamp 12. The limiting groove 122 corresponds to the position of the second support rod 53. The limiting groove 122 extends from the center of the bottom surface of the second clamp 12 to the axis of the second clamp 12. The second support rod 53 is away from the limiting support 54. One end of the second support rod 53 abuts against the limiting groove 122, which restricts the rotation angle of the second support rod 53. This prevents the end of the second support rod 53 from rotating away from the axis of the second clamp 12 when it abuts against the limiting groove 122. At the same time, under the combined action of the limiting support 54, the second support rod 53 cannot rotate when it is in working condition, and always remains vertical, providing stable support for the second clamp 12 on the basis of the base 5.

[0051] like Figure 7 The system includes a fixed rod 61, with a first fixed plate 62 fixedly connected to the bottom of the fixed rod 61. A first rotating sleeve 63 is fitted onto the fixed rod 61 and is rotatably connected to the fixed rod 61. A first rotating disk 64 and a second fixed disk 65 are fixedly connected to the first rotating sleeve 63. The first rotating disk 64 is located at the bottom of the first rotating sleeve 63 and above the first fixed disk 62, and the first rotating disk 64 and the first fixed disk 62 are slidably connected. The second fixed disk 65 is located above the first rotating disk 64. A second rotating sleeve 66 is fitted onto the first rotating sleeve 63 and is rotatably connected to the first rotating sleeve 63. A second rotating disk 67 is fixedly connected to the second rotating sleeve 66 and is located above the second fixed disk 65, and the second rotating disk 67 and the second fixed disk 65 are slidably connected. The top of the fixed rod 61, the first rotating sleeve 63, and the second rotating sleeve 66 are all provided with grooved knobs, which are convenient for operators to rotate by hand; The first rotating disk 64 has three first arc-shaped grooves 641, which are equidistantly arranged on the first rotating disk 64, with one end of each groove near the center of the first rotating disk 64 and the other end near the circumference of the first rotating disk 64; the second rotating disk 67 has three second arc-shaped grooves 671, which are equidistantly arranged on the second rotating disk 67, with one end of each groove near the center of the second rotating disk 67 and the other end near the circumference of the second rotating disk 67. A first sliding piece 621 is slidably disposed on the first fixed disk 62. The number of first sliding pieces 621 is equal to the number of first arc-shaped grooves 641 and they correspond one-to-one. A first guide post 6211 is disposed on the first sliding piece 621. The first guide post 6211 passes through the first arc-shaped groove 641, so that the first fixed disk 62 and the first rotating disk 64 are slidably connected. A second sliding piece 651 is slidably disposed on the second fixed disk 65. The number of second sliding pieces 651 is equal to the number of second arc-shaped grooves 671 and they correspond one-to-one. A second guide post 6511 is disposed on the second sliding piece 651. The second guide post 6511 passes through the second arc-shaped groove 671, so that the second fixed disk 65 and the second rotating disk 67 are slidably connected. The rotation of the first rotating sleeve 63 can control the rotation of the first rotating disk 64. At the same time, the cooperation of the first guide post 6211 and the first arc groove 641 causes the first sliding plate 621 to be pushed outward to abut the inner wall of the filter head. Rotating the second rotating sleeve 66 can drive the second rotating disk 67 to rotate, causing the second sliding plate 651 to be pushed outward to abut the inner wall of the cylinder, so that the cylinder and the filter head are concentric.

[0052] The implementation principle of Example 2 is as follows: When installing the filter head and the cylinder, the base 5 is first placed on the filter head to initially position the filter head. Then, the cylinder is inserted into the base 5, and the base 5 initially guides the cylinder to facilitate the installation of the cylinder and the filter head. At this time, the second support rod 53 and the second clamp 12 are both away from the cylinder. After the cylinder is inserted into the base 5, the second support rod 53 is flipped to make it vertical, and then the second clamp 12 is flipped to abut against the second support rod 53.

[0053] The first clamp 11 and the second clamp 12 are locked by the wing nut 13. At this time, the drive wheel 21 and the two driven wheels 22 press against the cylinder together to clamp the cylinder.

[0054] The movable fixing rod 61 is placed into the cylinder. First, the first rotating sleeve 63 is rotated. At this time, the first fixing plate 62 is fixed and the first rotating plate 64 rotates synchronously with the first rotating sleeve 63. Under the action of the first arc groove 641, the first guide post 6211 pushes the first sliding plate 621 outward. At this time, the three first sliding plates 621 unfold at the same time and abut against the inner wall of the filter head, so that the fixing rod 61 is concentric with the filter head. After the first sliding vane 621 abuts against the inner wall of the filter head, the second rotating sleeve 66 rotates. At this time, the first rotating sleeve 63 and the second fixed plate 65 are fixed and do not move. The second rotating plate 67 rotates synchronously with the second rotating sleeve 66. Under the action of the second arc groove 671, the second guide post 6511 pushes the second sliding vane 651 to slide outward. At this time, the three second sliding vanes 651 unfold at the same time and abut against the inner wall of the cylinder, so that the cylinder and the fixed rod 61 are concentric.

[0055] After the filter head, cylinder and fixing rod 61 are concentric, the second rotating sleeve 66 and the first rotating sleeve 63 are rotated in opposite directions to retract the second sliding plate 651 and the first sliding plate 621, and the fixing rod 61 is taken out from the sleeve.

[0056] After aligning the power tool with the connecting slot 311, start the power tool. The torque is transmitted sequentially through the first drive shaft 31, the first bevel gear 33, the second bevel gear 34, and the second drive shaft 32 to the drive wheel 21. The drive wheel 21 drives the cylinder and the driven wheel 22 to rotate synchronously for installation.

[0057] The meshing transmission of the first bevel gear 33 and the second bevel gear 34 changes the direction of the first drive shaft 31, allowing the operator to use a power tool to connect to the connecting groove 311 from the front and drive the first drive shaft 31.

[0058] After installation, remove the power tool, open the wing nut 13, flip the second clamp 12 to open it, then flip the second support rod 53 outwards and remove the base 5 from the filter head to complete the installation.

[0059] Rotating the first rotating sleeve 63 drives the first rotating disk 64 to rotate. Through the cooperation of the first arc-shaped groove 641 and the first guide post 6211, the first sliding vane 621 is driven to extend from the first fixed disk 62 and abut against the inner wall of the filter head. Rotating the second rotating sleeve 66 drives the second rotating disk 67 to rotate. Through the cooperation of the second arc-shaped groove 671 and the second guide post 6511, the second sliding vane 651 is driven to extend from the second fixed disk 65 and abut against the inner wall of the cylinder. The cooperation of the two can correct the axis of the filter head and the cylinder, ensuring that the two are completely concentric. This avoids the problems of thread seizing and workpiece damage caused by insufficient concentricity, and further improves the assembly accuracy and pass rate.

[0060] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
