Technical Field

[0001] The present application relates to the technical field of machine tool spindle cleaning, and in particular to an internal and external cleaner of a spindle. Background Art

[0002] Spindle cleaners are commonly used for cleaning and maintenance of machine tool spindles. For example, Chinese patent application number 2022230293054 discloses an internal and external spindle cleaning rod, including an integrally formed cleaning body and a connecting body; the cleaning body includes a longitudinal body and a transverse surface, and the surfaces of the longitudinal body and the transverse surface are provided with a plurality of arc-shaped grooves, and cylindrical cleaning cotton is embedded in the grooves to clean dirt on the inner hole and the external 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, causing the dirt on the cleaning cotton to be thicker, reducing the scraping effect of the cleaning cotton, and making it difficult to continue cleaning the dirt on the spindle. Summary of the invention

[0004] In order to improve the cleaning effect of the spindle, the present application provides a spindle internal and external cleaner.

[0005] The present application provides a spindle internal and external cleaner, which adopts the following technical solution: A spindle internal and external cleaner comprises a tapered tube, a handle tube, a strip sponge, a spiral sponge, a first mounting member and a second mounting member, wherein an end ring is coaxially fixed to the large end of the outer circumference of the tapered tube, the strip sponge is detachably fixed to the end face of the end ring by the second mounting member, a plurality of strip sponges are provided and each strip sponge is evenly arranged along the circumference of the end ring, and the length direction of the strip sponge is inclined to the radial direction of the end ring; the spiral sponge is coaxially arranged with the tapered tube, a spiral groove is provided on the outer circumference of the tapered tube, the cross section of the spiral groove is semicircular, the spiral sponge is embedded in the spiral groove, and the spiral sponge is detachably fixedly connected to the tapered tube by the first mounting member; the handle tube is fixed to the large end of the tapered tube.

[0006] By adopting the above technical scheme, by arranging a spiral sponge and a strip sponge, in the process of rotating the handle tube, not only can the dirt on the inner hole and the 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 of the main shaft along the axial direction of the main shaft, that is, part of the dirt in the inner hole of the main shaft is adhered by the spiral sponge, and part of the dirt is pushed by the spiral sponge and moved out of the inner hole of the main shaft, thereby reducing the thickness of the 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 along the radial direction of the main shaft to the axial center position of the main shaft, that is, the dirt pushed by the spiral sponge and the strip sponge will be gathered for unified collection.

[0007] Secondly, the first mounting member and the second mounting member are provided to facilitate replacement and maintenance of the spiral sponge and the strip sponge.

[0008] Optionally, the first mounting member is provided in plurality and arranged at intervals along the spiral path of the spiral sponge, the first mounting member comprises a first bolt and a pressing plate, the surface of the spiral sponge is provided with a first groove, the pressing plate is located in the first groove, the first bolt passes through the pressing plate and is threadably connected to the tapered tube, and the screw head of the first bolt is pressed against the pressing plate.

[0009] By adopting the above technical solution, by setting the first bolt and the pressing plate, not only can the 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 not easily separated from the spiral groove due to the friction force of the inner hole of the main shaft.

[0010] Optionally, the first mounting member includes a rubber rope and a rope clamp, the spiral sponge is penetrated with a through hole along the direction of its own spiral path, the rubber rope passes through the through hole, both ends of the rubber rope are located in the inner cavity of the conical tube, the two ends of the rubber rope are overlapped, the rope clamp is used to fix the overlapping part of the rubber rope, and the rubber rope is tightened; 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.

[0011] By adopting the above technical solution, during installation, the rubber rope is passed through the 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 tapered tube, and then the rubber rope is stretched and tightened so that the two ends of the rubber rope are overlapped, and then the overlapping part of the rubber rope is fixed with a rope clamp. As the rubber rope is tightened, the elastic force of the rubber rope will be applied to the spiral sponge, so that the spiral sponge is more tightly embedded in the spiral groove, thereby improving the anti-slip property of the spiral sponge.

[0012] Secondly, the overall force of the spiral sponge fitting in the spiral groove is more uniform, which reduces the occurrence of local exposure of the spiral sponge and makes the spiral sponge fit more evenly with the inner hole of the main shaft.

[0013] By providing an arc-shaped gasket, the exposed height of a local position 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 main shaft.

[0014] Optionally, the middle part of the rubber rope is set as a spiral part, and the end of the rubber rope is set as a connecting part. A spring is fixed in the spiral part, and the through hole is spiral, and the spiral part passes through the through hole; the rope clamp is used to fix the overlapping parts of the two connecting parts of the rubber rope, and the spring stretches and drives the spiral sponge to stretch along its own spiral path.

[0015] 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 exerts a force on the spiral sponge to stretch along its own spiral path, so that the spiral sponge is stretched, thereby reducing the radial stretching deviation of the spiral sponge under the action of external friction, thereby improving the stability of the dirt scraping effect.

[0016] Optionally, it also includes an exhaust structure, which includes a conical filter screen and an exhaust pipe, an annular scale storage groove is provided at the connection between the conical tube and the end ring, the inner wall of the large port of the conical tube is provided with a conical surface, and the groove wall of the scale storage groove is penetrated by multiple exhaust holes connected to the conical surface, the conical filter screen is fixedly connected to the handle tube, and the handle tube and the conical tube are detachably connected, the mesh surface of the conical filter screen is attached to the conical surface, and the exhaust pipe is connected to the inner cavity of the handle tube.

[0017] By adopting the above technical solution, the rotating spiral sponge and strip sponge push the dirt on the inner hole and outer end surface of the main shaft into the dirt storage tank respectively, and the air suction pipe applies negative pressure to the dirt storage tank, so that the dirt in the dirt storage tank is adsorbed on the conical filter net (drier dirt is more easily collected by negative pressure), that is, the dirt is collected uniformly to reduce the falling and scattering of the pushed dirt. In addition, there is real-time negative pressure in the dirt storage tank, so that the pushed dirt can be collected in time, thereby reducing the scraping pressure of the spiral sponge and strip sponge, and thus improving the cleaning effect.

[0018] Secondly, after the collection is completed, the handle tube can be removed to clean the dirt on the conical filter screen, which is more convenient.

[0019] Optionally, the end of the handle tube away from the conical tube is rotatably connected to an end cap, an air inlet pipe is passed through the axis of the end cap, and the air inlet pipe passes through the axis of the conical filter; the exhaust pipe is passed through and fixed to the end cap, and an annular exhaust cavity is formed between the inner circumference of the handle tube and the outer circumference of the air inlet pipe, and the exhaust pipe is connected to the scale storage tank through the exhaust cavity, the mesh of the conical filter, and the exhaust holes in sequence.

[0020] By adopting the above technical solution and setting up an air intake pipe, external air will enter the scale storage tank through the air intake pipe, the inner cavity of the tapered tube, the gap between the outer peripheral surface of the tapered tube and the inner hole of the main shaft in sequence. The gas flow on this path will carry the dirt pushed by the spiral sponge to improve the dirt collection and cleaning effects.

[0021] Secondly, external air can also enter the dirt storage tank through the gap between the end ring and the outer end face of the main shaft. The gas flow on this path will carry the dirt pushed by the strip sponge to improve the dirt collection and cleaning effects.

[0022] Optionally, it also includes a reciprocating drive structure, which includes a guide, a fixed tube, a sliding 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 is installed in the inner cavity of the tapered tube, and the guide is used to guide the connecting part so that the length direction of the connecting part is parallel to the axial direction of the tapered 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 with the fixed tube, and the tooth surfaces of the first bevel gear and the second bevel gear are arranged opposite to each other, the sliding rod is slidably penetrated into the fixed tube, and a long The strip-shaped sliding hole and the sliding rod are fixed with a rotation-stop block, the rotation-stop block slides with the sliding hole, the inner holes of the first bevel gear and the second bevel gear are each provided with a plurality of rotation-stop grooves evenly arranged circumferentially, and the rotation-stop block is used to plug and cooperate with one of the rotation-stop grooves; the third bevel gear, the fourth bevel gear, the first friction wheel and the second friction wheel are all rotationally connected to the inner wall of the tapered tube, the third bevel gear is meshed with the first bevel gear, the fourth bevel gear is meshed with the second bevel gear, the first driving wheel is coaxially fixed with the third bevel gear, 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.

[0023] By adopting the above technical solution, when the handle tube is rotated, the fixed tube remains stationary, the handle tube and the conical tube rotate relative to the fixed tube, the third bevel gear and the fourth bevel gear revolve around the axis of the fixed tube, and when the anti-rotation block cooperates with the anti-rotation groove of the first bevel gear, the anti-rotation block does not cooperate with the anti-rotation groove of the second bevel gear, the first bevel gear and the fixed tube are relatively fixed, and the second bevel gear and the fixed tube are relatively movable. Therefore, the third bevel gear has self-rotation power while revolving, while the fourth bevel gear has no self-rotation power while revolving, and the torque of the third bevel gear is transmitted to the first driving wheel, and the first driving wheel drives the connecting part to move forward, thereby driving the spiral sponge as a whole to move forward along its own spiral path direction.

[0024] When the anti-rotation block cooperates with the anti-rotation groove of the second bevel gear, the anti-rotation block does not cooperate with the anti-rotation groove of the first bevel gear, the second bevel gear is relatively fixed to the fixed tube, and the first bevel gear is relatively movable to the fixed tube. Therefore, the fourth bevel gear has self-rotation power while revolving, while the third bevel gear has no self-rotation power while revolving, and the torque of the fourth bevel gear is transmitted to the second driving wheel, and the second driving wheel 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.

[0025] From the above, it can be seen that during the rotation of the handle tube, through the reciprocating sliding slide rod, the anti-rotation block thereon cooperates with the anti-rotation grooves of the first bevel gear and the second bevel gear in turn, so as to drive the spiral sponge as a whole to reciprocate a small distance along its own spiral path direction, so that the movement direction of the spiral sponge relative to the inner hole of the main shaft is more diverse and the cleaning effect is stronger.

[0026] Optionally, the second mounting member includes a pressure strip and a second bolt, the surface of the strip sponge is penetrated by a second groove along its length direction, the pressure strip is embedded in the second groove, a long side edge of the pressure strip is bent to form a vertical plate, the vertical plate is pressed against one side groove wall of the second groove, and two second bolts respectively pass through the two ends of the pressure strip and are threadedly connected to the end ring.

[0027] By adopting the above technical solution, by setting the second bolt and the pressure strip, not only can the 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 not easily separated from the end ring due to the friction force of the outer end face of the main shaft.

[0028] Optionally, the thickness of the strip sponge gradually increases along the rotation direction of the end ring.

[0029] By adopting the above technical scheme, on the one hand, the situation where the friction force is too large due to the large contact area between the strip sponge and the outer end face of the main shaft can be reduced; on the other hand, the thickness of each part of the strip sponge is different, and the scraping effect of each part on the outer end face of the main shaft is different, so as to scrape the dirt layer by layer, that is, the thicker dirt will be pushed and thinned by the thinner thickness part of the strip sponge, while the thinner dirt will be wiped and adhered by the thinner thickness part of the strip sponge, thereby taking into account the pushing and scraping effects of the dirt on the outer end face of the main shaft.

[0030] Optionally, the notch edge of the second groove and the surface edge of the strip sponge are both chamfered.

[0031] In summary, the present application includes at least one of the following beneficial technical effects: By arranging the spiral sponge and the strip sponge, in the process of rotating the handle tube, not only can the dirt on the inner hole and the outer end face of the main shaft be scraped off, but the rotating spiral sponge can also carry the dirt on the inner hole of the main shaft away from the inner hole of the main shaft along the axial direction of the main shaft, that is, part of the dirt on the inner hole of the main shaft is adhered by the spiral sponge, and part of the dirt is pushed by the spiral sponge and moved out of the inner hole of the main shaft, thereby reducing the thickness of the dirt on the spiral sponge, thereby improving the cleaning effect; the rotating strip sponge can push the dirt on the outer end face of the main shaft along the radial direction of the main shaft to the axial center position of the main shaft, that is, the dirt pushed by the spiral sponge and the strip sponge will be gathered for unified collection; By setting a taut rubber rope, the elastic force of the rubber rope will be applied to the spiral sponge, so that the spiral sponge is more tightly embedded in the spiral groove, thereby improving the anti-slip property of the spiral sponge, and the force of the spiral sponge fitting the spiral groove more evenly, reducing the occurrence of partial exposure of the spiral sponge, and making the spiral sponge fit more evenly with the inner hole of the main shaft; The rotating spiral sponge and strip sponge push the dirt on the inner hole and outer end face of the main shaft into the dirt storage tank, and the air extraction pipe applies negative pressure to the dirt storage tank, so that the dirt in the dirt storage tank is adsorbed on the conical filter net (drier dirt is more easily collected by negative pressure), that is, the dirt is collected uniformly to reduce the falling and scattering of the pushed dirt. In addition, there is real-time negative pressure in the dirt storage tank, so that the pushed dirt can be collected in time, thereby reducing the scraping pressure of the spiral sponge and strip sponge, thereby improving the cleaning effect; During the rotation of the handle tube, the anti-rotation block on the reciprocating sliding slide rod cooperates with the anti-rotation grooves of the first bevel gear and the second bevel gear in turn to drive the spiral sponge as a whole to move back and forth a short distance along its own spiral path direction, so that the movement direction of the spiral sponge relative to the inner hole of the main shaft is more diverse and the cleaning effect is stronger.

DETAILED DESCRIPTION

[0044] The following is combined with Figure 1-11 This application is described in further detail.

[0045] Embodiment 1, Embodiment 1 discloses a spindle internal and external cleaner. 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 conical tube 1, a handle tube 12, a strip sponge 3, a spiral sponge 2, a first mounting part and a second mounting part, wherein an end ring 11 is coaxially fixed to the large end of the outer circumference of the conical tube 1 (the end of the conical tube 1 with a larger diameter is the large end, and the end of the conical tube 1 with a smaller diameter is the small end), and the handle tube 12 is coaxially fixed to the large end of the conical tube 1, and the handle tube 12 is used for the operator to hold.

[0046] The strip sponge 3 is arranged on the end surface of the end ring 11. There are multiple strip sponges 3, and each strip sponge 3 is evenly arranged along the circumference of the end ring 11. The length direction of the strip sponge 3 is inclined to the radial direction of the end ring 11. The thickness of the strip sponge 3 gradually increases along the rotation direction of the end ring 11. In other embodiments, the thickness of each part of the strip sponge 3 can be consistent, and the strip sponge 3 can be fixed by bonding.

[0047] In order to facilitate the subsequent replacement of the strip sponge 3, in this embodiment, the strip sponge 3 is detachably fixed to the end surface of the end ring 11 by a second mounting member, specifically, as follows: Figure 3 As shown, the second mounting member includes a pressure strip 32 and a second bolt 34. The surface of the strip sponge 3 is penetrated by a second groove 31 along its length direction. The pressure strip 32 is embedded in the second groove 31. One long side of the pressure strip 32 is bent to form a vertical plate 33. The vertical plate 33 is pressed against a side groove wall of the second groove 31. Two second bolts 34 pass through the two 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 are pressed against the pressure strip 32.

[0048] By setting the second bolt 34 and the pressure strip 32, not only can the 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 not easily separated from the end ring 11 due to the friction force of the outer end surface of the main shaft.

[0049] Furthermore, in other embodiments, chamfers are provided at the notch edges of the second groove 31 and the surface edges of the strip sponge 3 to reduce the occurrence of sponge edge breakage.

[0050] like Figure 1 , Figure 4 As shown, a spiral groove 101 is provided on the outer circumferential surface of the conical tube 1, and the cross-section of the spiral groove 101 is semicircular. The spiral sponge 2 is coaxially arranged with the conical tube 1, and a part of the structure of the spiral sponge 2 is embedded in the spiral groove 101, and the spiral sponge 2 is detachably fixedly connected with the conical tube 1 through a first mounting member. Specifically, a plurality of first mounting members are provided, and each first mounting member is arranged at intervals along the spiral path of the spiral sponge 2, that is, multi-point fixation of the spiral sponge 2 is achieved through a plurality of first mounting members.

[0051] The first mounting member includes a first bolt 23 and a pressing plate 22 . A first groove 21 is provided on the surface of the spiral sponge 2 . The pressing plate 22 is located in the first groove 21 . The first bolt 23 passes through the pressing plate 22 and is threadedly connected to the conical tube 1 . The screw head of the first bolt 23 presses against the pressing plate 22 .

[0052] By providing the first bolt 23 and the pressing plate 22, not only can the 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 it difficult for the spiral sponge 2 to be separated from the spiral groove 101 due to the friction force of the inner hole of the main shaft.

[0053] The implementation principle of Example 1 is as follows: insert the conical tube 1 into the inner hole of the main shaft, the spiral sponge 2 rests on the inner hole of the main shaft, and the strip sponge 3 rests on the outer end face of the main shaft, and then rotate the handle tube 12 to drive the end ring 11 and the conical tube 1 to rotate. In the process of rotating the handle tube 12, the spiral sponge 2 and the strip sponge 3 can not only scrape off the dirt on the inner hole and the outer end face of the main shaft, but also the rotating spiral sponge 2 can also carry the dirt in the inner hole of the main shaft away from the inner hole of the main shaft along the axial direction of the main shaft, that is, part of the dirt in the inner hole of the main shaft is adhered to the spiral sponge 2, and part of the dirt is pushed by the spiral sponge 2 and moved out of the inner hole of the main shaft, thereby reducing the dirt thickness on the spiral sponge 2 and thus improving the cleaning effect.

[0054] The rotating strip sponge 3 can push the dirt on the outer end surface of the main shaft along the main shaft radial direction to the axial center position of the main shaft, that is, the dirt pushed by the spiral sponge 2 and the strip sponge 3 will be gathered together for unified collection, and a collection dish can be placed under the gathering point for transportation after collection.

[0055] Secondly, by setting the thickness of each part of the strip sponge 3 to change, due to the different thicknesses of each part of the strip sponge 3, the scraping effects of parts with different thicknesses on the outer end face of the main shaft are different, so as to achieve layer-by-layer scraping of dirt, that is, thicker dirt will be pushed and thinned by the thinner thickness part of the strip sponge 3, while thinner dirt will be wiped off and adhered by the thinner thickness part of the strip sponge 3, thereby taking into account both the pushing and scraping effects of dirt on the outer end face of the main shaft.

[0056] Embodiment 2, embodiment 2 is different from embodiment 1 in that, Figure 5 , Figure 6 As shown, the first mounting member includes a rubber rope 51 and a rope clamp 52. The spiral sponge 2 is penetrated with a through hole 20 along its own spiral path direction. The rubber rope 51 passes through the through hole 20. The two ends of the rubber rope 51 respectively pass through the through holes opened in the conical tube 1 and enter the inner cavity of the conical tube 1. The two ends of the rubber rope 51 are overlapped. The rope clamp 52 is used to fix the overlapping part of the rubber rope 51 so that the rubber rope 51 forms a closed loop.

[0057] During installation, the rubber rope 51 is passed 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 stretched manually to ensure that the spiral sponge 2 is evenly wound around the conical tube 1, and 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, and then the rubber rope 51 is stretched and tightened, and the two ends of the rubber rope 51 are overlapped, and then the rope clamp 52 is used to fix the overlapping part of the rubber rope 51. Since the rubber rope 51 is tightened, the elastic force of the rubber rope 51 will be applied to the spiral sponge 2, so that the spiral sponge 2 is more tightly embedded in the spiral groove 101, thereby improving the anti-slip property of the spiral sponge 2.

[0058] Secondly, the force of the entire spiral sponge 2 fitting in the spiral groove 101 is more uniform, which reduces the occurrence of partial exposure of the spiral sponge 2, and makes the spiral sponge 2 fit more uniformly with the inner hole of the main shaft.

[0059] If the exposed surface of the spiral sponge 2 is uneven, an arc-shaped gasket 102 can be placed in the spiral groove 101. The arc-shaped gasket 102 is connected to the spiral groove 101 by sliding along the spiral path of the spiral groove 101. The arc-shaped gasket 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 so that the exposed height of each part of the spiral sponge 2 is consistent, thereby making the fit between the spiral sponge 2 and the inner hole of the main shaft more uniform. If the exposed surface of the spiral sponge 2 is uniform, the arc-shaped gasket 102 is not needed.

[0060] Embodiment 3, embodiment 3 is different from embodiment 2 in that, Figure 7 As shown, the middle part of the rubber rope 51 is set as the spiral part 511, and the end of the rubber rope 51 is set as the connecting part 512. A spring (not shown in the figure) is fixed in the spiral part 511, that is, when the rubber rope 51 is stretched, the spring will be stretched together.

[0061] The through hole 20 of the spiral sponge 2 is spiral, and the spiral portion 511 passes through the through hole 20 , that is, the spiral portion 511 can impose axial limitation on the spiral sponge 2 along the spiral path direction of the spiral sponge 2 .

[0062] The connecting portion 512 is integrally formed with a plurality of engaging protrusions 513 .

[0063] During installation, the rubber rope 51 is passed through the spiral sponge 2, and then the spiral sponge 2 is embedded in the spiral groove 101, which ensures that the spiral sponge 2 is evenly wound around the conical tube 1, and then the connecting parts 512 of the rubber rope 51 are respectively passed through the two through holes and placed in the inner cavity of the conical tube 1, and 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, and then the two connecting parts 512 of the rubber rope 51 are overlapped, and the bite protrusions 513 of the two connecting parts 512 are bite-engaged, and then the rope clamp 52 is used to fix the overlapping part of the rubber rope 51.

[0064] Since the spiral sponge 2 has a greater degree of stretching, the radial stretching deviation of the spiral sponge 2 due to the external friction force can be reduced, thereby improving the stability of the dirt scraping effect.

[0065] Embodiment 4, embodiment 4 is different from embodiment 3 in that, Figure 8 , Fig. 9 , Fig.10As shown, the spindle inner and outer 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 driving wheel 71, a first friction wheel 72, a second driving wheel 73 and a second friction wheel 74.

[0066] The guide member 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 portion 512 passes through the through hole and then bypasses the guide rod 63, that is, the guide rod 63 changes the extension direction of the connecting portion 512, so that the connecting portion 512 can be parallel to the axis of the tapered tube 1 (the connecting portion 512 is not colinear with the axis of the tapered tube 1).

[0067] A first rod 65, a second rod 651, a third rod 64 and a fourth rod 641 are provided in the conical tube 1. 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 conical tube 1.

[0068] 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 portion 512 as the center. The third rod 64 and the fourth rod 641 are symmetrically arranged with the connecting portion 512 as the center.

[0069] The first driving wheel 71 and the third bevel gear 75 are both coaxially fixedly connected to the first rod body 65 , the first friction wheel 72 is coaxially fixedly connected to the second rod body 651 , and the wheel surface of the first friction wheel 72 and the wheel surface of the first driving wheel 71 jointly clamp the connecting portion 512 .

[0070] The second driving wheel 73 and the fourth bevel gear 76 are both coaxially fixedly connected to the third rod 64 , the second friction wheel 74 is coaxially 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 clamp the connecting portion 512 together.

[0071] The fixed tube 61 is coaxially arranged with the conical tube 1, and the handle tube 12 is rotatably arranged relative to the fixed tube 61. Specifically, a plate body 121 is fixed in the handle tube 12, the fixed tube 61 passes through the plate body 121, and the fixed tube 61 is rotatably connected to the plate body 121. One end of the fixed tube 61 is located in the conical tube 1, and the other end of the fixed tube 61 is located on the outside of the handle tube 12.

[0072] The first bevel gear 77 and the second bevel gear 78 are both coaxially rotatably connected to the fixed tube 61, 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 axial slippage of the first bevel gear 78 and the second bevel gear 78 relative to the fixed tube 61, a stop ring 611 can be provided on the outer peripheral surface of the fixed tube 61.

[0073] The fourth bevel gear 76 is meshed with the second bevel gear 78 , the first driving wheel 71 is coaxially fixed with the third bevel gear 75 , and the second driving wheel 73 is coaxially fixed with the fourth bevel gear 76 .

[0074] The slide rod 62 is slidably inserted into the fixed tube 61. A long sliding hole 612 is opened on the surface of the fixed tube 61. A rotation-stop block 621 is fixed to the slide rod 62. The rotation-stop block 621 slides and cooperates with the sliding hole 612 to realize axial sliding of the slide rod 62 and the fixed tube 61, and the fixed tube 61 can also limit the rotation of the slide rod 62.

[0075] The inner holes of the first bevel gear 77 and the second bevel gear 78 are both provided with a plurality of anti-rotation grooves 70 evenly arranged around the circumference. The anti-rotation grooves 70 are arranged to penetrate the first bevel gear 77 and the second bevel gear 78 axially. The anti-rotation block 621 is used to be plugged into and cooperated with one of the anti-rotation grooves 70 .

[0076] When the handle tube 12 is rotated unidirectionally to clean the inner hole and outer end surface of the main shaft, the fixed tube 61 remains stationary (the operator can hold the fixed tube 61 with one hand to ensure that the fixed tube 61 does not rotate), the handle tube 12 and the conical tube 1 rotate relative to the fixed tube 61, and 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 cooperates with the anti-rotation groove 70 of the first bevel gear 77 (the anti-rotation block 621 does not cooperate 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 self-rotation power while revolving, while the fourth bevel gear 76 has no self-rotation power while revolving, and the torque of the third bevel gear 75 is transmitted to the first driving wheel 71, and the first driving wheel 71 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 direction.

[0077] By sliding the slide rod 62, the anti-rotation block 621 is matched with the anti-rotation groove 70 of the second bevel gear 78 (the anti-rotation block 621 is not matched 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 with the fixed tube 61. Therefore, the fourth bevel gear 76 has self-rotation power while revolving, while the third bevel gear 75 has no self-rotation power while revolving. The torque of the fourth bevel gear 76 is transmitted to the second driving wheel 73, and the second driving wheel 73 drives the connecting part 512 to move in the reverse direction, thereby driving the spiral sponge 2 as a whole to move in the reverse direction along its own spiral path.

[0078] From the above, it can be seen that during the rotation of the handle tube 12, through the reciprocating sliding slide rod 62, the anti-rotation block 621 thereon cooperates with the anti-rotation groove 70 of the first bevel gear 77 and the second bevel gear 78 in turn, so as to drive the spiral sponge 2 as a whole to reciprocate a small distance along its own spiral path direction, so that the movement direction of the spiral sponge 2 relative to the inner hole of the main shaft is more diverse and the cleaning effect is stronger.

[0079] In embodiment 5, the spindle internal and external cleaner further comprises an air extraction structure, which can also be used in embodiments 1-4. Fig.11 As shown (the arrow in the figure indicates the direction of air flow), the exhaust structure includes a conical filter screen 82 and an exhaust pipe 81, an annular scale storage tank 10 is provided at the connection between the conical tube 1 and the end ring 11, and the inner wall of the large end of the conical tube 1 is provided with a conical surface, and the wall of the scale storage tank 10 is penetrated by multiple exhaust holes 100 connected to the conical surface.

[0080] The handle tube 12 is detachably connected to the tapered tube 1 through a flange connection, and the tapered filter screen 82 is fixedly connected to the handle tube 12 , and the mesh surface of the tapered filter screen 82 is in contact with the tapered surface.

[0081] A circular plate 85 is fixed to the conical filter screen 82 , and the circular plate 85 separates the inner cavity of the conical tube 1 and the inner cavity of the handle tube 12 .

[0082] The end of the handle tube 12 away from the conical tube 1 is rotatably connected to the end cover 122, and an air inlet pipe 83 is passed through the axis of the end cover 122, and the air inlet pipe 83 passes through the axis of the circular plate 85, so that the inner cavity of the conical tube 1 is connected to the external atmosphere.

[0083] The exhaust pipe 81 is passed through and fixed to the end cover 122, and an annular exhaust cavity 30 is formed between the inner circumference of the handle tube 12 and the outer circumference of the air inlet pipe 83. The exhaust pipe 81 is connected to the scale storage tank 10 through the exhaust cavity 30, the mesh of the conical filter screen 82, and the exhaust hole 100 in sequence. One end of the exhaust pipe 81 is connected to an air suction pump (not shown in the figure).

[0084] The rotating spiral sponge 2 and strip sponge 3 push the dirt on the inner hole and outer end surface of the main shaft into the scale storage tank 10 respectively, and the exhaust pipe 81 performs exhaust, and the external air will enter the scale storage tank 10 through the air inlet pipe 83, the inner cavity of the tapered tube 1, and the gap between the outer peripheral surface of the tapered tube 1 and the inner hole of the main shaft in sequence. The gas flow on this path will carry the dirt pushed by the spiral sponge 2, so that the dirt enters the scale storage tank 10, and the dirt in the scale storage tank 10 is adsorbed on the conical filter screen 82 (wherein 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.

[0085] 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 surface of the main shaft. The gas flow on this path will carry the dirt pushed by the strip sponge 3 and make the dirt enter the scale storage tank 10.

[0086] After the collection is completed, the handle tube 12 can be removed to clean the dirt on the conical filter screen 82.

[0087] In summary, the air extraction structure can form a stable movement of the airflow, so that the pushed dirt is collected more quickly and timely and concentratedly into the scale storage tank 10, thereby reducing the scraping pressure of the spiral sponge 2 and the strip sponge 3, thereby improving the cleaning effect.

[0088] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
