The illustrative embodiments and descriptions of the present utility model are only used to explain the present utility model and are not used to limit the present utility model.

[0043] Embodiment

[0044] As Figures 2 to 10 shown, the present utility model includes a pump body 3, a telescopic unit is provided on the pump body 3, a fixed block 11 is provided at the movable end of the telescopic unit, a first cavity, a second cavity and a third cavity are provided in the fixed block 11, the first cavity is communicated with the third cavity through a first connection hole 41, and the second cavity is communicated with the third cavity through a second connection hole 42; a movable rod 10 is provided in the first cavity, a grinding unit 9 is provided on the movable rod 10, an expansion member 33 communicated with the third cavity through an air pipe 34 is provided in the grinding unit 9, a connecting rod 30 is provided at the top of the grinding unit 9, one end of the connecting rod 30 is connected to the expansion member 33, and a first grinding disc 29 is provided at the other end; a movable block 44 is provided in the second cavity, and the movable block 44 is connected to the movable rod 10 through a cross bar 46; an air inlet hole is provided on the fixed block 11, the air inlet hole communicates the third cavity with the pump body 3, an adjusting block 40 is provided in the third cavity, and a third connection hole is provided on the adjusting block 40, and the third connection hole is used to communicate with one of the first connection hole 41 or the second connection hole 42.

[0045] For the prior art in the case of Figure 1When the stepped coupling workpiece 6 shown is polished, the traditional polishing device cannot well polish the stepped surface of the workpiece 6, and the traditional manual polishing method is quite laborious. Therefore, in this technical solution, a pump body 3 is provided. When the pump body 3 works, it can output gas with a certain pressure. A telescopic unit is provided on the pump body 3. When the telescopic unit works, it can move in the vertical direction, so as to adjust the height of the polishing unit 9 in the vertical direction, and then polish the outer surface of the workpiece 6 one by one. When polishing the workpiece 6, first place the workpiece 6 upright and ensure that the stepped surface of the workpiece 6 is facing down. This placement can ensure that during the polishing of the workpiece 6, the iron filings generated by polishing will not accumulate at the steps of the workpiece 6, improving the polishing quality of the workpiece 6.

[0046] After the placement of the workpiece 6 is completed, the pressure gas is conveyed into the third cavity of the fixed block 11 by the provided pump body 3. Since in the initial state, the third connection hole on the adjusting block 40 in the third cavity is in communication with the first connection hole 41, therefore, the pressure gas entering the third cavity can enter the first cavity through the first connection hole 41, thereby pushing the moving rod 10 in the first cavity to drive the polishing unit 9 to move towards the outer surface of the workpiece 6, and finally making the polishing unit 9 closely attached to the outer surface of the workpiece 6. Therefore, when the workpiece 6 rotates in the horizontal direction, in cooperation with the telescopic unit, the outer surface of the workpiece 6 can be effectively polished.

[0047] During the polishing process, when the telescopic unit drives the polishing unit 9 to gradually move upwards, when the first polishing disc 29 on the polishing unit 9 contacts the stepped surface of the workpiece 6, the first polishing disc 29 can polish the stepped surface and remove the burrs on the stepped surface. As the telescopic unit continues to move the polishing unit 9 upwards, the stepped surface of the workpiece 6 squeezes the first polishing disc 29. Under the action of the connecting rod 30, the expansion member 33 in the polishing unit 9 can be squeezed, so that the expansion member 33 is squeezed. When the expansion member 33 is squeezed, the gas inside it will be transferred to the third cavity through the air pipe 34, pushing the adjusting block 40 in the third cavity to move. During the movement of the provided adjusting block 40, the third connection hole is gradually disconnected from the first connection hole 41, and the third connection hole is connected to the second connection hole 42. At this time, the gas conveyed by the pump body 3 into the third cavity will enter the second cavity through the second connection hole 42, pushing the moving block 44 in the second cavity to move away from the moving rod 10. During the movement of the moving block 44, under the action of the cross bar 46, the moving rod 10 is pulled back, thus realizing the automatic adjustment of the position of the polishing unit 9 at the steps.

[0048] After the first grinding disc 29 on the grinding unit 9 completely moves away from the step of the workpiece 6, after the extrusion of the first grinding disc 29 by the step of the workpiece 6 is removed, the provided expansion member 33 gradually recovers its deformation. During the process of recovering its deformation, the expansion member 33 pushes the connecting rod 30 to protrude from the grinding unit 9 again, so that the side wall of the first grinding disc 29 fits on the outer surface above the step surface of the workpiece 6; at the same time, during the process of recovering its deformation, the expansion member 33 generates a certain negative pressure, attracting the adjusting block 40 located in the third cavity to move back again, disconnecting the connection between the third connection hole and the second connection hole 42, so that the third connection hole is reconnected to the first connection hole 41. Therefore, at this time, the pressurized gas introduced into the third cavity will enter the first cavity again through the first connection hole 41, and cooperate with the telescopic unit to make the grinding unit 9 closely adhere to the outer surface above the step surface of the workpiece 6, and grind the outer surface of this section of the workpiece 6.

[0049] The telescopic unit includes a fixed cylinder 4 and a vertical rod 12. One end of the fixed cylinder 4 is fixed to the top of the pump body 3, and the other end is sleeved on the vertical rod 12. The outer diameter of the vertical rod 12 is the same as the inner diameter of the fixed cylinder 4, and the top of the vertical rod 12 is connected to the fixed block 11; the pump body 3 is internally connected to the fixed cylinder 4.

[0050] In this embodiment, in order to be able to adjust the height of the fixed block 11 in the vertical direction, so as to ensure that the grinding unit 9 can grind the outer surface of the vertically placed workpiece 6 one by one, a fixed cylinder 4 is provided on the top of the pump body 3. A vertical rod 12 with the same inner diameter as the fixed cylinder 4 is provided in the fixed cylinder 4, and the inside of the fixed cylinder 4 is connected to the pump body 3. When the pump body 3 conveys a certain amount of pressurized gas into the fixed cylinder 4, the pressurized gas entering the fixed cylinder 4 can push the vertical rod 12 to move upward under the action of air pressure, thereby realizing the adjustment of the height of the fixed block 11.

[0051] In another embodiment, the provided telescopic unit is a cylinder or a hydraulic cylinder.

[0052] The inner diameter of the adjusting block 40 is the same as the inner diameter of the third cavity. A notch communicating with the air inlet hole is provided on one side of the adjusting block 40. The third connection hole is located on the other side of the adjusting block 40, and the third connection hole communicates with the notch; a second elastic member 39 is also provided in the third cavity. The second elastic member 39 is connected to one end of the adjusting block 40, and the second elastic member 39 is used to pull the adjusting block 40 to connect the third connection hole with the first connection hole 41.

[0053] In the present embodiment, in order to ensure that the third connecting hole on the adjusting block 40 can be connected with the first connecting hole 41 or the second connecting hole 42, a notch is provided on the circumferential side wall of the adjusting block 40 of the cylindrical structure, and a sealed space is formed between the notch and the inner wall of the third cavity, and the sealed space is connected to the air inlet connected to the pump body 3, so that the pressurized gas generated by the pump body 3 can enter the notch through the air inlet.

[0054] In the initial state, the set adjusting block 40 pulls the third connecting hole on the adjusting block 40 and the first connecting hole 41 to be in a connected state under the action of the second elastic member 39. At this time, when the pump body 3 is used to transport gas to the notch of the adjusting block 40, the gas entering the notch passes through the third connecting hole and the first connecting hole 41 one by one and enters the first cavity of the fixed block 11. The pressurized gas entering the first cavity acts on the end of the movable rod 10 located in the first cavity, thereby pushing the movable rod 10 to extend out of the fixed block 11, and finally makes the grinding unit 9 contact the surface of the workpiece 6, and the outer wall of the workpiece 6 is ground by the grinding unit 9.

[0055] When the telescopic unit drives the first grinding disc 29 on the grinding unit 9 to move to contact the step surface of the workpiece 6, as the step surface continuously squeezes the first grinding disc 29, the expansion member 33 is squeezed, so that the gas inside the expansion member 33 is squeezed into the third cavity provided with the second elastic member 39, thereby pushing the adjustment block 40 in the third cavity to move. During the movement of the adjustment block 40, the first connecting hole 41 and the third connecting hole that were originally in a connected state are staggered, and the third connecting hole is connected with the second connecting hole 42. In this way, the gas entering the notch of the pump body 3 will enter the second cavity of the fixed block 11 through the second connecting hole 42, pushing the movable block 44 located in the second cavity to move. During the movement, the movable block 44 uses the cross bar 46 to pull the movable rod 10 back, to ensure that the grinding unit 9 on the movable rod 10 can smoothly pass through the step of the workpiece 6.

[0056] The fixed block 11 is also provided with a pressure relief hole connected to the third cavity. In order to ensure that the adjustment block 40 in the third cavity can move smoothly in the third cavity, the third connecting hole is connected with the second connecting hole 42. Therefore, a pressure relief hole is provided so that when the adjustment block 40 moves, the air between the moving end of the adjustment block 40 and the third cavity can be discharged through the pressure relief hole.

[0057] The grinding unit 9 includes a connecting head 32 and a second grinding disc 31. One end of the connecting head 32 is connected to the movable rod 10, and the other end is connected to the second grinding disc 31. An installation cavity is provided inside the connecting head 32. One end of the expansion member 33 is fixed in the installation cavity, and the other end is connected to the connecting rod 30. A third elastic member is further provided inside the expansion member 33, and the third elastic member is distributed along the axial direction of the connecting rod 30.

[0058] In this embodiment, in order to ensure that the provided grinding unit 9 can effectively grind the outer surface of the workpiece 6, a second grinding disc 31 is provided on the connecting head 32 connected to the movable rod 10. The provided second grinding disc 31 is perpendicular to the first grinding disc 29 in space. That is, the provided second grinding disc 31 is used to grind the circumferential side wall of the vertically placed workpiece 6, and the provided first grinding disc 29 is used to grind the stepped surface of the workpiece 6, ensuring that the outer wall of the workpiece 6 can be effectively ground.

[0059] In order to ensure that the expansion member 33 can quickly recover its deformation after the first grinding disc 29 is removed from the extrusion of the stepped surface of the workpiece 6, a third elastic member is provided inside the expansion member 33. The elastic force generated by the third elastic member can support the expansion member 33 to quickly recover its deformation.

[0060] In order to ensure that the expansion member 33 can expand and contract linearly, the expansion member 33 is preferably a corrugated pipe with closed ends at both ends. The provided air pipe 34 is communicated with the inside of the corrugated pipe. Therefore, when the corrugated pipe is extruded by the connecting rod 30, the gas inside it can be transferred to the third cavity through the air pipe 34, pushing the regulating block 40 in the third cavity to move.

[0061] A pull rope is further provided inside the air pipe 34. One end of the pull rope is connected to the regulating block 40, and the other end is connected to the movable end of the expansion member 33.

[0062] In this way, when the movable end of the expansion member 33 recovers its deformation, it can quickly pull the regulating block 40 back under the action of the pull rope.

[0063] The fixed block 11 is further provided with a first exhaust hole and a second exhaust hole. The first exhaust hole is communicated with the first cavity, the second exhaust hole is communicated with the second cavity, and first air valves 43 are provided in both the first exhaust hole and the second exhaust hole.

[0064] In this embodiment, the function of the cross bar 46 is to ensure that when the movable block 44 moves in the second cavity, the cross bar 46 can pull the movable rod 10 back. In this embodiment, in order to ensure that the movable rod 10 or the movable block 44 can retract smoothly, a first exhaust hole and a second exhaust hole are respectively provided on the fixed block 11. When gas is delivered into the first cavity to make the movable rod 10 extend out of the fixed block 11, the first air valve 43 in the first exhaust hole is closed, and the first air valve 43 in the second exhaust hole is opened. In this way, during the process of the cross bar 46 pulling the movable block 44 back, the air in the second cavity will be discharged through the first air valve 43; and when gas is introduced into the second cavity, the first air valve 43 in the second exhaust hole is closed, and the first air valve 43 in the first exhaust hole is opened. When the movable block 44 moves in the second cavity and the cross bar 46 pulls the movable rod 10 back, the gas in the first cavity can be discharged through the first exhaust hole.

[0065] A third exhaust hole 45 is further provided on the fixed block 11, and the third exhaust hole 45 communicates with the second cavity.

[0066] In order to ensure that the movable block 44 can move smoothly in the second cavity, a third exhaust hole 45 is provided.

[0067] It further includes a base 1 and a processing table 8, and the pump body 3 is fixed on the base 1; a support column 5 and a rotating mechanism 2 are further provided on the base 1. The support column 5 is used to connect with the bottom of the processing table 8, and the vertical rod 12 vertically penetrates the processing table 8; a rotating shaft 14 is provided at the output end of the rotating mechanism 2, a groove is provided at the top of the rotating shaft 14, and a first telescopic tube 24 with both ends being closed structures is provided in the groove. The top of the first telescopic tube 24 is further provided with a lifting rod 22, the lifting rod 22 vertically penetrates the processing table 8, and a clamping member 13 for clamping the workpiece 6 is provided at the top of the lifting rod 22.

[0068] When clamping the workpiece 6 with the clamping tooling in the prior art, most clamping toolings act on the outer wall of the workpiece 6, which causes the place where the workpiece 6 is clamped to be unable to be polished. Therefore, the clamping member 13 is designed in this embodiment. In order to ensure that the clamped workpiece 6 can automatically rotate on the horizontal plane, so as to cooperate with the polishing unit 9 to realize the polishing of the outer surface of the workpiece 6, the rotating mechanism 2 is provided. The rotating mechanism 2 is a motor. The workpiece 6 to be polished is fixed on the clamping member 13 by using the clamping member 13 on the rotating mechanism 2. In this way, when the rotating mechanism 2 works, it drives the clamping member 13 to rotate, thereby realizing the rotation of the workpiece 6, and cooperating with the first polishing disc 29 and the second polishing disc 31, the outer wall of the workpiece 6 can be polished.

[0069] Meanwhile, in this embodiment, in order to ensure that the workpiece 6 can be placed upright on the clamping member 13, the workpiece 6 to be polished is placed upright on the processing table 8, and the top of the processing table 8 is used to position the workpiece 6 to avoid the workpiece 6 being in a skewed state. However, this causes the bottom surface of the workpiece 6 to contact the upper surface of the processing table 8. When the workpiece 6 starts to rotate under the action of the rotating mechanism 2, the processing table 8 will cause wear on the bottom surface of the workpiece 6, affecting the quality of the product. Therefore, in this embodiment, a first telescopic tube 24 and a lifting rod 22 are further provided in the rotating shaft 14. After the workpiece 6 is clamped by the clamping member 13, the first telescopic tube 24 is used to push the lifting rod 22 to move upward a small distance, avoiding the contact between the bottom of the workpiece 6 and the top of the processing table 8, so as to ensure that the workpiece 6 will not be worn by the processing table 8 during the rotation process.

[0070] A guide groove 26 is further provided on the inner wall of the groove, and a guide block 25 connected to the side wall of the lifting rod 22 is provided in the guide groove 26.

[0071] In this embodiment, in order to ensure that the lifting rod 22 located in the groove of the rotating shaft 14 can not only move in the vertical direction but also rotate with the rotating shaft 14, a guide groove 26 is provided in the groove of the rotating shaft 14, and a guide block 25 is provided on the side wall of the lifting rod 22. Under the combined action of the guide block 25 and the guide groove 26, it is ensured that the lifting rod 22 can rotate synchronously with the rotating shaft 14 at any position in the groove.

[0072] The clamping member 13 includes a turntable 19, a driving gear 21, a plurality of driven gears 20 and a plurality of inner support rods 17. A fifth cavity is provided inside the turntable 19, the driving gear 21 is located in the fifth cavity, and the driving gear 21 is sleeved on the lifting rod 22; a movable shaft 18 with the same number as the number of the driven gears 20 is further provided in the fifth cavity, the lengths of the movable shafts 18 increase one by one, the driven gears 20 are sleeved on the respective movable shafts 18, and the driven gears 20 are all meshed with the driving gear 21; one end of the movable shaft 18 is rotatably connected to the turntable 19, and the other side extends outside the turntable 19, and the inner support rod 17 is connected to the side wall of the movable shaft 18 outside the turntable 19.

[0073] In this embodiment, in order to ensure that the provided clamping member 13 can clamp the inner wall of the workpiece 6, a driving gear 21 and a plurality of driven gears 20 are provided on the turntable 19. After the rotating mechanism 2 drives the lifting rod 22 to rotate, the lifting rod 22 drives the driving gear 21 to rotate. When the driving gear 21 rotates, it will drive each driven gear 20 to rotate. When the driven gear 20 rotates, it will drive the movable shaft 18 to rotate, and further make the inner support rod 17 on the side wall of the movable shaft 18 rotate towards the inner wall of the workpiece 6, and finally make the inner support rod 17 tightly press on the inner wall of the workpiece 6 to fix the workpiece 6 on the turntable 19.

[0074] In this embodiment, in order to avoid interference between the inner support rods 17 at the same height, the lengths of the respective movable shafts 18 are all different, thus ensuring that the respective inner support rods 17 are at different heights in the vertical direction.

[0075] A sphere 16 is further provided at the clamping end of the inner support rod 17, and the provided sphere 16 can play a certain protective role on the inner wall of the workpiece 6.

[0076] A circular groove is further provided at the top of the processing table 8. A second expansion tube 7 is provided in the circular groove. The second expansion tube 7 is connected to the pump body 3 through a hose. One end of the second expansion tube 7 is connected to the inner wall of the circular groove, and a clamping plate 15 is provided at the other end.

[0077] In this embodiment, in order to ensure that when the inner support rod 17 of the clamping member 13 clamps the workpiece 6, the workpiece 6 of the type with a relatively high center of gravity does not fall over, a second expansion tube 7 and a clamping plate 15 are further provided on the processing table 8. After the workpiece 6 is placed upright in the circular groove of the processing table 8, pressurized gas is introduced into the second expansion tube 7 by the pump body 3. Since the provided second expansion tube 7 is a corrugated tube, it can expand and stretch along its axial direction, thereby pushing the clamping plate 15 to clamp the bottom port of the workpiece 6, avoiding the workpiece 6 with a relatively high center of gravity from falling over when the clamping member 13 clamps the workpiece 6.

[0078] A first elastic member is further provided in the second expansion tube 7. The first elastic member is distributed along the axial direction of the second expansion tube 7. The provided first elastic member can pull the second expansion tube 7 to quickly retract, thereby transferring the gas in the second expansion tube 7 to the first expansion tube 24.

[0079] A convex portion is further provided at the center of the circular groove of the processing table 8. A cavity 28 is provided inside the convex portion. The lifting rod 22 vertically penetrates the convex portion, and a part of the lifting rod 22 is located inside the cavity 28; a first conduit 27 is further provided inside the lifting rod 22. One end of the first conduit 27 extends into the first expansion tube 24, and the other end communicates with the cavity 28; the second expansion tubes 7 all communicate with the cavity 28 through a second conduit, and a second air valve is provided in the second conduit.

[0080] After clamping the workpiece 6 with the clamping plate 15, start the rotating mechanism 2. Under the action of the rotating shaft 14, drive the lifting rod 22 to rotate synchronously, so that the inner support rod 17 presses tightly against the inner wall of the workpiece 6, fixing the workpiece 6 on the turntable 19. Then open the second air valve in the second conduit, so that the gas in the second telescopic tube 7 can be transferred into the cavity 28. After that, the gas in the cavity 28 enters the first telescopic tube 24 through the first conduit 27, causing the first telescopic tube 24 to expand in the vertical direction, increasing the height of the lifting rod 22. Furthermore, the workpiece 6 fixed on the turntable 19 can be lifted a small distance on the processing table 8, removing the contact between the processing table 8 and the bottom of the workpiece 6. The turntable 19 drives the workpiece 6 to continue rotating under the continuous rotation of the lifting rod 22, cooperating with the grinding unit 9 to grind the outer surface of the workpiece 6.

[0081] A positioning groove is also provided at the top of the convex portion, and a positioning ball 23 matching the positioning groove is provided at the bottom of the turntable 19. The positioning ball 23 can be inserted into the positioning groove.

[0082] When driving the driving gear 21 to rotate during the rotation of the lifting rod 22, in order to prevent the turntable 19 from rotating synchronously, resulting in the inner support rod 17 being unable to effectively support the inner wall of the workpiece 6, a positioning groove is provided on the convex portion, and a positioning ball 23 is provided at the bottom of the turntable 19. In the initial state, before the lifting rod 22 is lifted, the positioning ball 23 at the bottom of the turntable 19 is located in the positioning groove of the convex portion. In this way, when the lifting rod 22 rotates, the turntable 19 cannot rotate synchronously, thus ensuring that the lifting rod 22 can effectively drive the rotation of the driving gear 21, expand each inner support rod 17 one by one and act on the inner wall of the workpiece 6 to realize the clamping of the workpiece 6; when the clamping of the workpiece 6 is completed, open the second air valve, so that the gas in the second telescopic tube 7 is transferred into the first telescopic tube 24. After lifting the lifting rod 22, the lifting rod 22 moves the positioning ball 23 at the bottom of the turntable 19 out of the positioning groove. At this time, during the rotation of the lifting rod 22, it will drive the turntable 19 to rotate synchronously, and then drive the workpiece 6 to rotate together.

[0083] The above specific implementation manners have further detailed the purpose, technical solutions and beneficial effects of the present invention. It should be understood that the above are only the specific implementation manners of the present invention and are not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
