Abstract
Description
Technical Field
[0001] This application relates to the field of machine tool spindle cleaning technology, and in particular to a spindle internal and external cleaner. Background Technology
[0002] Spindle cleaners are commonly used for cleaning and maintaining machine tool spindles. For example, Chinese patent application number 2022230293054 discloses a spindle internal and external cleaning rod, which includes an integrally formed cleaning body and a connecting body. The cleaning body includes a longitudinal body and a transverse body. The surfaces of the longitudinal body and the transverse body are provided with multiple arc-shaped grooves. Cylindrical cleaning cotton is embedded in the grooves to clean the dirt in the inner hole and the outer end face of the spindle at the same time.
[0003] When there is a lot of dirt on the spindle, the cleaning cotton on the spindle cleaner will stick to most of the dirt, resulting in a thick layer of dirt on the cleaning cotton. This reduces the scraping effect of the cleaning cotton and makes it difficult to continue cleaning the dirt on the spindle. Summary of the Invention
[0004] To improve the cleaning effect of the spindle, this application provides a spindle internal and external cleaner.
[0005] This application provides a spindle internal and external cleaner, which adopts the following technical solution:
[0006] A spindle internal and external cleaner includes a tapered tube, a handle, strip-shaped sponges, a spiral sponge, a first mounting component, and a second mounting component. An end ring is coaxially fixed to the large end of the outer circumference of the tapered tube. Multiple strip-shaped sponges are evenly distributed along the circumference of the end ring, with their length direction inclined to the radial direction of the end ring. The spiral sponge is coaxially arranged with the tapered tube, and a spiral groove is provided on the outer circumference of the tapered tube. The spiral groove has a semi-circular cross-section, and the spiral sponge is embedded within the spiral groove. The spiral sponge is detachably fixed to the tapered tube via the first mounting component. The handle is fixed to the large end of the tapered tube.
[0007] By adopting the above technical solution, and by setting up spiral sponges and strip sponges, during the rotation of the handle tube, not only can the dirt in the inner hole and outer end face of the main shaft be scraped off, but the rotating spiral sponge can also carry the dirt in the inner hole of the main shaft away from the inner hole along the main shaft axis. That is, some dirt in the inner hole of the main shaft is adhered to by the spiral sponge, while some dirt is pushed out of the inner hole by the spiral sponge, thereby reducing the thickness of dirt on the spiral sponge and improving the cleaning effect. The rotating strip sponge can push the dirt on the outer end face of the main shaft radially to the axis of the main shaft. That is, the dirt pushed by the spiral sponge and strip sponge will be collected for unified collection.
[0008] Secondly, by setting up the first and second mounting components, the replacement and maintenance of the spiral sponge and the strip sponge can be facilitated.
[0009] Optionally, the first mounting component is provided in multiple parts and arranged at intervals along the spiral path of the spiral sponge. The first mounting component includes a first bolt and a pressure plate. The surface of the spiral sponge is provided with a first groove. The pressure plate is located in the first groove. The first bolt passes through the pressure plate and is threadedly connected to the tapered pipe. The screw head of the first bolt presses against the pressure plate.
[0010] By adopting the above technical solution and setting the first bolt and pressure plate, not only can detachable installation be achieved, but the spiral sponge can also be fixed in the spiral groove by pressing, which has strong stability and makes the spiral sponge less likely to be detached from the spiral groove due to the friction of the spindle inner hole.
[0011] Optionally, the first mounting component includes a rubber rope and a rope clamp. The spiral sponge has a through hole along its own spiral path, the rubber rope passes through the through hole, and both ends of the rubber rope are located in the inner cavity of the tapered tube. The two ends of the rubber rope overlap, and the rope clamp is used to fix the overlap of the rubber rope, so that the rubber rope is taut. An arc-shaped gasket is slidably connected in the spiral groove along its own spiral path, and the arc-shaped gasket is located between the spiral sponge and the groove wall of the spiral groove.
[0012] By adopting the above technical solution, during installation, a rubber rope is threaded through a spiral sponge, and then the spiral sponge is embedded in the spiral groove. At this time, both ends of the rubber rope are placed in the inner cavity of the conical tube. Then, the rubber rope is stretched taut, so that the two ends of the rubber rope overlap. Then, the overlapping part of the rubber rope is fixed with a rope clamp. Because the rubber rope is taut, the elasticity of the rubber rope will be applied to the spiral sponge, making the spiral sponge more tightly embedded in the spiral groove, thereby improving the anti-detachment property of the spiral sponge.
[0013] Secondly, the force of the spiral sponge fitting into the spiral groove is more uniform, reducing the occurrence of local exposure of the spiral sponge and making the fit between the spiral sponge and the inner hole of the main shaft more uniform.
[0014] By setting arc-shaped shims, the exposed height of local parts of the spiral sponge can be adjusted, so that the exposed height of each part of the spiral sponge is consistent, so that the spiral sponge fits more evenly with the inner hole of the spindle.
[0015] Optionally, the middle part of the rubber rope is designated as a spiral part, and the end of the rubber rope is designated as a connecting part. A spring is fixed inside the spiral part, and the through hole is spiral-shaped, with the spiral part passing through the through hole. The rope clip is used to fix the overlapping part of the two connecting parts of the rubber rope, and the spring is stretched and drives the spiral sponge to stretch along its own spiral path.
[0016] By adopting the above technical solution, through the cooperation of the perforation and the spiral part, when the rubber rope is stretched, the spiral part applies a stretching force to the spiral sponge along its own spiral path, causing the spiral sponge to stretch. This reduces the occurrence of radial stretching and displacement of the spiral sponge under the action of external friction, thereby improving the stability of the dirt scraping effect.
[0017] Optionally, it also includes an air extraction structure, which includes a conical filter screen and an air extraction pipe. An annular scale storage groove is provided at the connection between the conical pipe and the end ring. The inner wall of the large end of the conical pipe is provided with a conical surface. The groove wall of the scale storage groove has multiple air extraction holes that communicate with the conical surface. The conical filter screen is fixedly connected to the handle tube, and the handle tube is detachably connected to the conical pipe. The mesh surface of the conical filter screen is attached to the conical surface, and the air extraction pipe communicates with the inner cavity of the handle tube.
[0018] By employing the above technical solution, the rotating spiral sponge and strip sponge respectively push the dirt from the inner hole and outer end face of the main shaft into the dirt collection tank. The suction pipe applies negative pressure to the dirt collection tank, causing the dirt in the tank to be adsorbed onto the conical filter screen (drier dirt is more easily collected by negative pressure), thus uniformly collecting the dirt and reducing the falling and scattering of the pushed dirt. Furthermore, the real-time negative pressure within the dirt collection tank ensures that the pushed dirt is collected promptly, thereby reducing the scraping pressure of the spiral and strip sponges and improving the cleaning effect.
[0019] Secondly, after collection is complete, the handle can be removed to clean the dirt on the conical filter screen, which is quite convenient.
[0020] Optionally, an end cap is rotatably connected to the end of the handle tube away from the conical tube. An air inlet pipe passes through the axis of the end cap and through the axis of the conical filter screen. An air extraction pipe is fixed to the end cap. An annular air extraction chamber is formed between the inner circumferential surface of the handle tube and the outer circumferential surface of the air inlet pipe. The air extraction pipe communicates with the scale storage tank by passing through the air extraction chamber, the mesh of the conical filter screen, and the air extraction hole in sequence.
[0021] By adopting the above technical solution, and by setting up an air intake pipe, external air will sequentially pass through the air intake pipe, the inner cavity of the conical tube, and the gap between the outer circumference of the conical tube and the inner hole of the main shaft to enter the scale storage tank. During the gas flow along this path, the scale pushed by the spiral sponge will be carried to improve the scale collection effect and cleaning effect.
[0022] Secondly, external air can also enter the scale storage tank through the gap between the end ring and the outer end face of the main shaft. During the gas flow along this path, the dirt pushed by the strip sponge will be carried to improve the dirt collection and cleaning effect.
[0023] Optionally, a reciprocating drive structure is also included, comprising a guide member, a fixed tube, a slide rod, a first bevel gear, a second bevel gear, a third bevel gear, a fourth bevel gear, a first driving wheel, a first friction wheel, a second driving wheel, and a second friction wheel. The guide member is installed inside the conical tube and guides the connecting part so that the length direction of the connecting part is parallel to the axial direction of the conical tube. The fixed tube is coaxially arranged with the handle tube, and the handle tube is rotatably arranged relative to the fixed tube. The first bevel gear and the second bevel gear are both coaxially rotatably connected to the fixed tube, and the tooth surfaces of the first bevel gear and the second bevel gear are arranged opposite to each other. The slide rod slides through the fixed tube, and the surface of the fixed tube has a long... The slide has a strip-shaped hole, and a sliding rod is fixed with an anti-rotation block. The anti-rotation block slides and engages with the slide hole. The inner holes of the first and second bevel gears are each provided with multiple circumferentially evenly arranged anti-rotation grooves. The anti-rotation block is used to engage with one of the anti-rotation grooves. The third bevel gear, the fourth bevel gear, the first friction wheel, and the second friction wheel are all rotatably connected to the inner wall of the tapered tube. The third bevel gear meshes with the first bevel gear, and the fourth bevel gear meshes with the second bevel gear. The first driving wheel is coaxially fixed with the third bevel gear, and the second driving wheel is coaxially fixed with the fourth bevel gear. The wheel surface of the first friction wheel and the wheel surface of the first driving wheel jointly clamp the connecting part, and the wheel surface of the second friction wheel and the wheel surface of the second driving wheel jointly clamp the connecting part.
[0024] By adopting the above technical solution, when the handle is rotated, the fixed tube remains stationary, while the handle and the tapered tube rotate relative to the fixed tube. The third and fourth bevel gears revolve around the axis of the fixed tube. When the anti-rotation block engages with the anti-rotation groove of the first bevel gear, the anti-rotation block does not engage with the anti-rotation groove of the second bevel gear. The first bevel gear is relatively fixed to the fixed tube, while the second bevel gear is relatively movable to the fixed tube. Therefore, the third bevel gear has rotational power while revolving, while the fourth bevel gear has no rotational power while revolving. The torque of the third bevel gear is transmitted to the first driving wheel, which drives the connecting part to move forward, thereby driving the spiral sponge as a whole to move forward along its own spiral path.
[0025] When the anti-rotation block engages with the anti-rotation groove of the second bevel gear, the anti-rotation block does not engage with the anti-rotation groove of the first bevel gear. The second bevel gear is relatively fixed to the fixed tube, while the first bevel gear is relatively movable to the fixed tube. Therefore, the fourth bevel gear has rotational power while revolving, while the third bevel gear has no rotational power while revolving. The torque of the fourth bevel gear is transmitted to the second driving wheel, which drives the connecting part to move in the opposite direction, thereby driving the spiral sponge as a whole to move in the opposite direction along its own spiral path.
[0026] As can be seen from the above, during the rotation of the handle tube, the anti-rotation block on the reciprocating sliding rod engages with the anti-rotation grooves of the first and second bevel gears in sequence, thereby driving the spiral sponge to move back and forth a small distance along its own spiral path, making the movement direction of the spiral sponge relative to the inner hole of the main shaft more diverse and the cleaning effect stronger.
[0027] Optionally, the second mounting component includes a pressure strip and a second bolt. The surface of the strip-shaped sponge has a second groove extending along its length. The pressure strip is embedded in the second groove. A vertical plate is bent into a long side of the pressure strip. The vertical plate abuts against one side wall of the second groove. Two second bolts pass through both ends of the pressure strip and are threadedly connected to the end ring.
[0028] By adopting the above technical solution and setting the second bolt and pressure strip, not only can detachable installation be achieved, but the strip sponge can also be fixed to the end ring by pressing, which has strong stability and makes the strip sponge less likely to be detached from the end ring due to friction from the outer end face of the spindle.
[0029] Optionally, the thickness of the strip-shaped sponge gradually increases along the rotation direction of the end ring.
[0030] By adopting the above technical solution, firstly, it can reduce the occurrence of excessive friction caused by the large contact area between the strip sponge and the outer end face of the spindle. Secondly, the different thicknesses of the strip sponge result in different scraping effects on the outer end face of the spindle, thus achieving layer-by-layer scraping of dirt. That is, thicker dirt will be pushed and thinned by the thinner parts of the strip sponge, while thinner dirt will be wiped off and adhered by the thinner parts of the strip sponge, thereby taking into account both the pushing and scraping / adhesion effects on the dirt on the outer end face of the spindle.
[0031] Optionally, both the groove edge of the second groove and the surface edge of the strip-shaped sponge have chamfers.
[0032] In summary, this application includes at least one of the following beneficial technical effects:
[0033] By incorporating spiral and strip-shaped sponges, during the rotation of the handle, not only can dirt be scraped off from the inner bore and outer end face of the spindle, but the rotating spiral sponge can also carry dirt away from the inner bore of the spindle along the spindle axis. That is, some dirt in the inner bore of the spindle is adhered to by the spiral sponge, while some dirt is pushed out of the inner bore by the spiral sponge, thereby reducing the thickness of dirt on the spiral sponge and improving the cleaning effect. The rotating strip-shaped sponge can push dirt on the outer end face of the spindle radially to the spindle axis. In other words, the dirt pushed by the spiral and strip sponges will be collected for unified collection.
[0034] By setting a taut rubber rope, the elasticity of the rubber rope will be applied to the spiral sponge, making the spiral sponge more tightly embedded in the spiral groove, thereby improving the anti-loosening property of the spiral sponge. In addition, the force of the spiral sponge adhering to the spiral groove is more uniform, reducing the occurrence of local exposure of the spiral sponge, and making the fit between the spiral sponge and the inner hole of the main shaft more uniform.
[0035] The rotating spiral and strip-shaped sponges push the dirt from the inner hole and outer end face of the main shaft into the dirt collection tank, respectively. The suction pipe applies negative pressure to the tank, causing the dirt to be adsorbed onto the conical filter screen (drier dirt is more easily collected by the negative pressure). This unified collection of dirt reduces the amount of dirt that falls and scatters. Furthermore, the real-time negative pressure within the tank ensures timely collection of the pushed dirt, reducing the scraping pressure from the spiral and strip-shaped sponges and thus improving cleaning efficiency.
[0036] During the rotation of the handle, the anti-rotation block on the reciprocating sliding rod engages with the anti-rotation grooves of the first and second bevel gears in sequence, thereby driving the spiral sponge to move back and forth a small distance along its own spiral path. This makes the movement direction of the spiral sponge relative to the inner hole of the main shaft more diverse and the cleaning effect stronger. Attached Figure Description

[0049] The following is in conjunction with the appendix Figure 1-11 This application will be described in further detail.
[0050] Example 1 discloses a spindle internal and external cleaner. (Refer to...) Figure 1 and Figure 2 (The direction of the arrow in the figure is the rotation direction of the handle tube 12). The spindle internal and external cleaner includes a tapered tube 1, a handle tube 12, a strip-shaped sponge 3, a spiral sponge 2, a first mounting component, and a second mounting component. The large end of the outer circumference of the tapered tube 1 is coaxially fixed with an end ring 11 (the end with the larger diameter of the tapered tube 1 is the large end, and the end with the smaller diameter of the tapered tube 1 is the small end). The handle tube 12 is coaxially fixed to the large end of the tapered tube 1 and is used for the operator to hold.
[0051] Strip-shaped sponges 3 are disposed on the end face of the end ring 11. Multiple strip-shaped sponges 3 are disposed, and each strip-shaped sponge 3 is evenly distributed around the end ring 11. The length direction of the strip-shaped sponges 3 is inclined to the radial direction of the end ring 11. The thickness of the strip-shaped sponges 3 gradually increases along the rotation direction of the end ring 11. In other embodiments, the thickness of each part of the strip-shaped sponge 3 can be the same. The strip-shaped sponges 3 can be fixed by adhesive bonding.
[0052] To facilitate subsequent replacement of the strip-shaped sponge 3, in this embodiment, the strip-shaped sponge 3 is detachably fixed to the end face of the end ring 11 by the second mounting component, specifically, as follows: Figure 3 As shown, the second mounting component includes a pressure strip 32 and a second bolt 34. A second groove 31 is formed through the surface of the strip-shaped sponge 3 along its own length direction. The pressure strip 32 is embedded in the second groove 31. A vertical plate 33 is formed by bending one long side of the pressure strip 32. The vertical plate 33 abuts against one side wall of the second groove 31. Two second bolts 34 pass through both ends of the pressure strip 32 respectively. The second bolts 34 are threadedly connected to the end ring 11, and the screw heads of the second bolts 34 abut against the pressure strip 32.
[0053] By setting the second bolt 34 and pressure strip 32, not only can detachable installation be achieved, but the strip sponge 3 can also be fixed to the end ring 11 by pressing, which has strong stability and makes the strip sponge 3 less likely to be detached from the end ring 11 due to friction force on the outer end face of the spindle.
[0054] Furthermore, in other embodiments, chamfers are provided at the edge of the groove 31 and the surface edge of the strip sponge 3 to reduce the occurrence of sponge edge breakage.
[0055] like Figure 1 , Figure 4 As shown, the outer circumferential surface of the tapered tube 1 is provided with a spiral groove 101. The cross-section of the spiral groove 101 is semi-circular. The spiral sponge 2 is coaxially arranged with the tapered tube 1. Part of the structure of the spiral sponge 2 is embedded in the spiral groove 101. The spiral sponge 2 is detachably and fixedly connected to the tapered tube 1 through the first mounting member. Specifically, there are multiple first mounting members, and each first mounting member is arranged at intervals along the spiral path of the spiral sponge 2. That is, the spiral sponge 2 is fixed at multiple points through multiple first mounting members.
[0056] The first mounting component includes a first bolt 23 and a pressure plate 22. The surface of the spiral sponge 2 is provided with a first groove 21. The pressure plate 22 is located in the first groove 21. The first bolt 23 passes through the pressure plate 22 and is threadedly connected to the tapered tube 1. The head of the first bolt 23 presses against the pressure plate 22.
[0057] By setting the first bolt 23 and the pressure plate 22, not only can detachable installation be achieved, but the spiral sponge 2 can also be fixed in the spiral groove 101 by pressing, which has strong stability and makes the spiral sponge 2 less likely to be detached from the spiral groove 101 by the friction of the spindle inner hole.
[0058] The implementation principle of Example 1 is as follows: The tapered tube 1 is inserted into the inner hole of the spindle, the spiral sponge 2 is placed against the inner hole of the spindle, and the strip sponge 3 is placed against the outer end face of the spindle. Then, the handle tube 12 is rotated to drive the end ring 11 and the tapered tube 1 to rotate. During the rotation of the handle tube 12, the spiral sponge 2 and the strip sponge 3 can not only scrape off the dirt in the inner hole and the outer end face of the spindle, but also the rotating spiral sponge 2 can carry the dirt in the inner hole of the spindle away from the inner hole of the spindle along the spindle axis. That is, part of the dirt in the inner hole of the spindle is adhered to by the spiral sponge 2, while part of the dirt is pushed out of the inner hole of the spindle by the spiral sponge 2, thereby reducing the thickness of dirt on the spiral sponge 2 and thus improving the cleaning effect.
[0059] The rotating strip-shaped sponge 3 can push the dirt on the outer end face of the main shaft radially to the center of the main shaft. That is, the dirt pushed by the spiral sponge 2 and the strip-shaped sponge 3 will be collected for unified collection. A collection dish can also be placed below the collection point for easy transfer after collection.
[0060] Secondly, by setting varying thicknesses in different parts of the strip sponge 3, the different thicknesses of the different parts of the strip sponge 3 result in different scraping effects on the outer end face of the spindle, thus achieving layer-by-layer scraping of dirt. That is, thicker dirt will be pushed and thinned by the thinner parts of the strip sponge 3, while thinner dirt will be wiped off and adhered by the thinner parts of the strip sponge 3, thereby taking into account both the pushing and scraping / adhesion effects on the outer end face of the spindle.
[0061] Example 2 differs from Example 1 in that, as Figure 5 , Figure 6 As shown, the first mounting component includes a rubber rope 51 and a rope clamp 52. The spiral sponge 2 has a through hole 20 along its own spiral path. The rubber rope 51 passes through the through hole 20. The two ends of the rubber rope 51 pass through the through holes opened in the tapered tube 1 and enter the inner cavity of the tapered tube 1. The two ends of the rubber rope 51 overlap. The rope clamp 52 is used to fix the overlap of the rubber rope 51 so that the rubber rope 51 forms a closed loop.
[0062] During installation, the rubber rope 51 is threaded through the spiral sponge 2, and then the spiral sponge 2 is embedded in the spiral groove 101. At this time, the spiral sponge 2 needs to be manually stretched to ensure that the spiral sponge 2 is evenly wound on the conical tube 1. Then, the two ends of the rubber rope 51 are respectively passed through the two through holes and placed in the inner cavity of the conical tube 1. Then, the rubber rope 51 is stretched taut, and the two ends of the rubber rope 51 are overlapped. Then, the overlapped part of the rubber rope 51 is fixed with the rope clamp 52. As the rubber rope 51 is taut, the elasticity of the rubber rope 51 will be applied to the spiral sponge 2, making the spiral sponge 2 more tightly embedded in the spiral groove 101, thereby improving the anti-detachment property of the spiral sponge 2.
[0063] Secondly, the force of the spiral sponge 2 fitting into the spiral groove 101 is more uniform, reducing the occurrence of local exposure of the spiral sponge 2, and making the fit between the spiral sponge 2 and the inner hole of the main shaft more uniform.
[0064] If the exposed surface of the spiral sponge 2 is uneven, an arc-shaped shim 102 can be placed inside the spiral groove 101. The arc-shaped shim 102 slides and connects with the spiral groove 101 along its spiral path. The arc-shaped shim 102 can be moved between the spiral sponge 2 and the groove wall of the spiral groove 101 to adjust the exposed size of the spiral sponge 2, making the exposed height of each part of the spiral sponge 2 consistent, thus ensuring a more uniform fit between the spiral sponge 2 and the inner hole of the spindle. If the exposed surface of the spiral sponge 2 is uniform, the arc-shaped shim 102 is not needed.
[0065] Example 3 differs from Example 2 in that, as Figure 7 As shown, the middle part of the rubber rope 51 is designated as a spiral part 511, and the end of the rubber rope 51 is designated as a connecting part 512. A spring (not shown in the figure) is fixed inside the spiral part 511, that is, when the rubber rope 51 is stretched, it will drive the spring to stretch as well.
[0066] The perforations 20 of the spiral sponge 2 are spiral-shaped, and the spiral part 511 passes through the perforations 20. That is, the spiral part 511 can apply axial limiting to the spiral sponge 2 along the spiral path direction of the spiral sponge 2.
[0067] The connecting parts 512 are integrally formed and have multiple interlocking protrusions 513.
[0068] During installation, the rubber rope 51 is threaded through the spiral sponge 2, and then the spiral sponge 2 is embedded in the spiral groove 101. This ensures that the spiral sponge 2 is evenly wound around the tapered tube 1. Then, the connecting part 512 of the rubber rope 51 is passed through the two through holes and placed in the inner cavity of the tapered tube 1. Then, the rubber rope 51 is stretched and tightened, and the spiral part 511 and the spring are stretched to apply a stretching force to the spiral sponge 2 along its own spiral path, so that the spiral sponge 2 is stretched along its own spiral path. Then, the two connecting parts 512 of the rubber rope 51 are overlapped, and the interlocking protrusions 513 of the two connecting parts 512 are interlocked. Then, the overlapping part of the rubber rope 51 is fixed by the rope clamp head 52.
[0069] Because the spiral sponge 2 has a large degree of stretching, it can reduce the occurrence of radial stretching and displacement of the spiral sponge 2 under the action of external friction, thereby improving the stability of the dirt scraping effect.
[0070] Example 4 differs from Example 3 in that, as Figure 8 , Figure 9 , Figure 10As shown, the spindle internal and external cleaner also includes a reciprocating drive structure, which includes a guide, a fixed tube 61, a slide rod 62, a first bevel gear 77, a second bevel gear 78, a third bevel gear 75, a fourth bevel gear 76, a first drive wheel 71, a first friction wheel 72, a second drive wheel 73, and a second friction wheel 74.
[0071] The guide is a guide rod 63, which is fixed in the inner cavity of the tapered tube 1. The guide rod 63 is perpendicular to the axis of the tapered tube 1. The connecting part 512 passes through the through hole and then goes around the guide rod 63. That is, the guide rod 63 changes the extension direction of the connecting part 512, so that the connecting part 512 can be parallel to the axis of the tapered tube 1 (the connecting part 512 and the axis of the tapered tube 1 are not collinear).
[0072] The tapered tube 1 is provided with a first rod 65, a second rod 651, a third rod 64 and a fourth rod 641. The first rod 65, the second rod 651, the third rod 64 and the fourth rod 641 are all perpendicular to the guide rod 63. The first rod 65, the second rod 651, the third rod 64 and the fourth rod 641 are all rotatably connected to the tapered tube 1.
[0073] The first rod 65 and the second rod 651 are located directly above the third rod 64 and the fourth rod 641. The first rod 65 and the second rod 651 are symmetrically arranged with the connecting part 512 as the center, and the third rod 64 and the fourth rod 641 are symmetrically arranged with the connecting part 512 as the center.
[0074] The first driving wheel 71 and the third bevel gear 75 are both coaxially and fixedly connected to the first rod 65. The first friction wheel 72 is coaxially and fixedly connected to the second rod 651, and the wheel surface of the first friction wheel 72 and the wheel surface of the first driving wheel 71 together clamp the connecting part 512.
[0075] The second driving wheel 73 and the fourth bevel gear 76 are both coaxially and fixedly connected to the third rod 64. The second friction wheel 74 is coaxially and fixedly connected to the fourth rod 641, and the wheel surface of the second friction wheel 74 and the wheel surface of the second driving wheel 73 together clamp the connecting part 512.
[0076] The fixed tube 61 is coaxially arranged with the tapered tube 1, and the handle tube 12 is rotatably arranged relative to the fixed tube 61. Specifically, a plate 121 is fixed inside the handle tube 12, the fixed tube 61 passes through the plate 121, and the fixed tube 61 is rotatably connected to the plate 121. One end of the fixed tube 61 is located inside the tapered tube 1, and the other end of the fixed tube 61 is located outside the handle tube 12.
[0077] The first bevel gear 77 and the second bevel gear 78 are both rotatably connected to the fixed tube 61 on the same axis, and the tooth surfaces of the first bevel gear 77 and the second bevel gear 78 are arranged opposite to each other. In order to reduce the occurrence of axial slippage of the first bevel gear and the second bevel gear 78 relative to the fixed tube 61, an anti-detachment ring 611 can be provided on the outer circumferential surface of the fixed tube 61.
[0078] The fourth bevel gear 76 meshes with the second bevel gear 78, the first driving gear 71 is coaxially fixed with the third bevel gear 75, and the second driving gear 73 is coaxially fixed with the fourth bevel gear 76.
[0079] The slide rod 62 is slidably inserted through the fixed tube 61. The surface of the fixed tube 61 is provided with an elongated sliding hole 612. The slide rod 62 is fixed with an anti-rotation block 621. The anti-rotation block 621 and the sliding hole 612 slide and cooperate, thereby realizing the axial sliding of the slide rod 62 and the fixed tube 61. The fixed tube 61 can also restrict the rotation of the slide rod 62.
[0080] The inner holes of the first bevel gear 77 and the second bevel gear 78 are provided with multiple circumferentially evenly arranged anti-rotation grooves 70. The anti-rotation grooves 70 are arranged to pass through the first bevel gear 77 and the second bevel gear 78 along the axial direction. The anti-rotation block 621 is used to insert and cooperate with one of the anti-rotation grooves 70.
[0081] When the handle 12 is rotated in one direction to clean the inner hole and outer end face of the spindle, the fixed tube 61 remains stationary (the operator can hold the fixed tube 61 with one hand to ensure that it does not rotate). The handle 12 and the tapered tube 1 rotate relative to the fixed tube 61. The third bevel gear 75 and the fourth bevel gear 76 revolve around the axis of the fixed tube 61. By sliding the slide rod 62, the anti-rotation block 621 engages with the anti-rotation groove 70 of the first bevel gear 77 (the anti-rotation block 621 does not engage with the anti-rotation groove 70 of the second bevel gear 78). At this time, the first bevel gear 77 is relatively fixed to the fixed tube 61, and the second bevel gear 78 is relatively movable to the fixed tube 61. Therefore, the third bevel gear 75 has rotational power while revolving, while the fourth bevel gear 76 does not have rotational power while revolving. The torque of the third bevel gear 75 is transmitted to the first drive wheel 71, which drives the connecting part 512 to move forward, thereby driving the spiral sponge 2 as a whole to move forward along its own spiral path.
[0082] By sliding the slide bar 62, the anti-rotation block 621 engages with the anti-rotation groove 70 of the second bevel gear 78 (the anti-rotation block 621 does not engage with the anti-rotation groove 70 of the first bevel gear 77). At this time, the second bevel gear 78 is relatively fixed to the fixed tube 61, and the first bevel gear 77 is relatively movable to the fixed tube 61. Therefore, the fourth bevel gear 76 has rotational power while revolving, while the third bevel gear 75 has no rotational power while revolving. The torque of the fourth bevel gear 76 is transmitted to the second driving wheel 73, which drives the connecting part 512 to move in the opposite direction, thereby driving the spiral sponge 2 as a whole to move in the opposite direction along its own spiral path.
[0083] As can be seen from the above, during the rotation of the handle tube 12, the anti-rotation block 621 on the reciprocating sliding rod 62 engages with the anti-rotation groove 70 of the first bevel gear 77 and the second bevel gear 78 in sequence, so as to drive the spiral sponge 2 to move back and forth a small distance along its own spiral path, making the movement direction of the spiral sponge 2 relative to the inner hole of the main shaft more diverse and the cleaning effect stronger.
[0084] Example 5: The spindle internal and external cleaner also includes an air extraction structure, which can also be used in Examples 1-4. Figure 11 As shown (arrows in the figure indicate airflow direction), the air extraction structure includes a conical filter screen 82 and an air extraction pipe 81. An annular scale storage tank 10 is provided at the connection between the conical pipe 1 and the end ring 11. The inner wall of the large end of the conical pipe 1 is provided with a conical surface. The tank wall of the scale storage tank 10 has multiple air extraction holes 100 that connect to the conical surface.
[0085] The handle tube 12 and the conical tube 1 are detachably connected by a flange connection. The conical filter screen 82 is fixedly connected to the handle tube 12, and the mesh surface of the conical filter screen 82 is attached to the conical surface.
[0086] The conical filter screen 82 is fixed with a circular plate 85, which separates the inner cavity of the conical tube 1 and the inner cavity of the handle tube 12.
[0087] An end cap 122 is rotatably connected to the end of the handle tube 12 away from the conical tube 1. An air inlet pipe 83 is provided at the axis of the end cap 122 and passes through the axis of the circular plate 85. The air inlet pipe 83 allows the inner cavity of the conical tube 1 to communicate with the external atmosphere.
[0088] The suction pipe 81 is fixed to the end cap 122. The inner circumferential surface of the handle 12 and the outer circumferential surface of the air inlet pipe 83 form an annular suction chamber 30. The suction pipe 81 passes through the suction chamber 30, the mesh of the conical filter screen 82, and the suction hole 100 in sequence to communicate with the scale storage tank 10. One end of the suction pipe 81 is connected to a suction pump (not shown in the figure).
[0089] The rotating spiral sponge 2 and strip sponge 3 push the dirt in the inner hole and outer end face of the main shaft into the dirt storage tank 10, respectively. The air extraction pipe 81 extracts air, and the external air will enter the dirt storage tank 10 through the air inlet pipe 83, the inner cavity of the conical tube 1, and the gap between the outer circumference of the conical tube 1 and the inner hole of the main shaft. During the gas flow along this path, the dirt pushed by the spiral sponge 2 will be carried into the dirt storage tank 10. The dirt in the dirt storage tank 10 is adsorbed on the conical filter screen 82 (the drier dirt is more easily carried by the airflow), that is, the dirt is collected uniformly to reduce the falling and scattering of the pushed dirt.
[0090] At the same time, external air can also enter the scale storage tank 10 through the gap between the end ring 11 and the outer end face of the spindle. During the gas flow along this path, the dirt pushed by the strip sponge 3 will be carried into the scale storage tank 10.
[0091] After collection, the handle 12 can be removed to clean the dirt on the conical filter screen 82.
[0092] In summary, the suction structure can create a stable airflow, which allows the pushed dirt to be collected more quickly and efficiently into the dirt storage tank 10, thereby reducing the scraping pressure of the spiral sponge 2 and the strip sponge 3 and improving the cleaning effect.
[0093] 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.
