Description

Technical Field

[0001] The invention relates to the technical field of exhaust pipe processing, in particular to a polishing device used for exhaust pipe processing. Background Art

[0002] Exhaust pipe polishing is a method of surface treatment for automobile exhaust pipes. Usually, automobile exhaust pipes are made of stainless steel or chrome materials, and because exhaust pipes are generally of an irregular shape, the polishing of exhaust pipes is more difficult. Therefore, the polishing of exhaust pipes currently requires the use of a bending pipe polishing machine.

[0003] At present, the general working process of the pipe bending polishing machine is as follows: first, one end of the exhaust pipe is manually inserted into the pipe bending polishing machine, and the exhaust pipe is located between the upper and lower sanding belts in the polishing machine. The polishing machine is started to drive the sanding belt to rotate, thereby polishing the surface of the exhaust pipe. During this process, it is necessary to manually control the other end of the exhaust pipe at all times and push the exhaust pipe to move, especially when the polishing reaches the special-shaped bend. At this time, it is necessary to manually use clever force to offset the exhaust pipe so that the special-shaped part of the exhaust pipe can pass through the sanding belt smoothly. If you are not careful, the surface of the exhaust pipe may be easily scratched. This operation method not only requires the operator to have certain technical experience, but also greatly restricts the efficiency of polishing. Summary of the invention

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] like Figure 1 As shown, the present invention provides a technical solution: a polishing device for exhaust pipe processing, comprising a horizontally placed polishing table 1, first slide grooves 2 are provided on both sides of the polishing table 1, a fixed seat 3 is movably provided in the first slide groove 2, a fixing bolt for positioning is provided on the fixed seat 3, and a clamping mechanism 4 with an adjustable opening size is provided on the fixed seat 3.

[0038] like Figure 6-7 As shown, the clamping mechanism 4 is used to fix the exhaust pipe a. The clamping mechanism 4 includes a rod body 41. A servo motor 42 with a self-locking function is arranged inside the rod body 41. A rotatable driving gear 43 is installed at the output end of the servo motor 42. The driving gear 43 is located on the outside of the rod body 41, and a plurality of groups of rotatable clamps 44 are also arranged on the rod body 41.

[0039] like Figure 6-7As shown, the clamp 44 is located outside the driving gear 43, and the side of the clamp 44 close to the driving gear 43 is circular, and the circular side is provided with a row of teeth 441, and the teeth 441 mesh with the driving gear 43. Figure 6 When the servo motor 42 rotates clockwise, it can drive the four sets of clamps 44 to rotate counterclockwise, so that the four sets of clamps 44 stretch outward and then clamp on the inner wall of the exhaust pipe. Conversely, when the servo motor 42 rotates counterclockwise, it will drive the clamps 44 to rotate clockwise, thereby driving the clamps 44 to retract inward, thereby loosening the exhaust pipe and facilitating the removal of the exhaust pipe. This clamping mechanism 4 can be used to clamp exhaust pipes of different pipe opening sizes and has strong adaptability.

[0040] like Figure 6 As shown, the number of the clamps 44 is at least three, and four are provided in the present application, and the side of the clamp 44 away from the driving gear 43 is a clamping portion, and the clamping portion is in an arc shape.

[0041] like Figure 1 As shown, the polishing table 1 is also provided with a grid mesh plate 5 for discharging waste and two sets of second slide grooves 6. A rotatable first screw rod 7 is arranged in the second slide groove 6. The first screw rod 7 is driven by an external first motor 8. A horizontally slidable machine base 9 is installed between the first screw rods 7 by threaded cooperation.

[0042] like Figure 1-2 and Figure 8 As shown, a second slide groove 10 is provided on the top of the machine base 9, and a rotatable second screw rod 11 is arranged in the second slide groove 10. The second screw rod 11 is driven by an external second motor 12. A traveling frame 13 which can slide back and forth is installed on the second screw rod 11 by threaded cooperation. An angle plate (not shown in the figure) can be arranged at the bottom of the traveling frame 13 to grasp the deflection angle of the polishing cover 15. A third motor 14 (with a self-locking function, which can fix the current deflection angle) is arranged in the middle of the traveling frame 13. A rotatable polishing cover 15 is installed at the output end of the third motor 14, and a groove body 151 is arranged at the lower part of the polishing cover 15.

[0043] like Figure 2 , 8 As shown, the bottom of the walking frame 13 is circular, and a fourth slide groove 31 is provided at the bottom of the walking frame 13. A T-shaped slide shaft 32 is provided at the top of the polishing cover 15. The T-shaped slide shaft 32 can be slidably arranged in the fourth slide groove 31. The significance of this design is that the weight of the polishing cover 15 can be borne by the T-shaped slide shaft 32, thereby reducing the load pressure of the third motor 14.

[0044] like Figure 3 As shown, a rotatable grinding wheel 16 is disposed at the bottom of the inner cavity of the polishing cover 15 , a polishing groove 161 is opened in the middle of the grinding wheel 16 , and the polishing groove 161 is concentrically disposed with the groove body 151 .

[0045] like Figure 4 As shown, the polishing cover 15 is also provided with a rotatable first gear set 17 and a second gear set 19, the first gear set 17 is meshed with the second gear set 19, the first gear set 17 is connected to the grinding wheel 16 through a first belt 18, a rotatable sleeve 20 is provided in the middle of the grinding wheel 16, and the second gear set 19 is connected to the sleeve 20 through a second belt 21.

[0046] like Figure 5 As shown, a group of rotatable pulleys 22 are respectively provided on the upper and lower sides of the grinding wheel 16, and a polishing belt 24 is transmission-connected between each group of pulleys 22. It should be noted that, regarding the spacing between the polishing belts 24 on the upper and lower sides, one of the pulleys 22 in each group is transmission-connected to the sleeve 20 through a third belt 23.

[0047] like Figure 4 As shown, a plurality of limit wheels 33 are provided on one side of the grinding wheel 16, and the plurality of limit wheels 33 are used to limit the second belt 21 and the third belt 23 respectively. The purpose of providing the limit wheels 33 is to ensure that the second belt 21 and the third belt 23 are always kept in a taut state.

[0048] like Figure 3 As shown, it also includes a dust suction component, which includes a dust collector 26 and a dust suction pipe 27 located on one side of the polishing cover 15. The dust suction pipe 27 is annular in shape, and the dust suction pipe 27 is concentrically arranged with the groove body 151. By turning on the vacuum cleaner 26, the dust and debris generated during the polishing process can be absorbed through the dust suction pipe 27.

[0049] like Figure 1 , 8 As shown, it also includes a cleaning component, which includes a water tank 28 and a high-pressure pump 29 located on the top of the machine base 9. The water outlet of the high-pressure pump 29 is connected to a high-pressure atomizing nozzle 30 through a water pipe. The high-pressure atomizing nozzle 30 is installed on the machine base 9 and close to the side of the polishing belt 24. When the high-pressure pump 29 is turned on, the water in the water tank 28 is sprayed out through the high-pressure atomizing nozzle 30, thereby absorbing the escaped dust.

[0050] As another embodiment, we can also directly set the high-pressure atomizing nozzle 30 on the tank body 151, so that the dust can be directly absorbed and flushed away from the discharge port 25 by high pressure.

[0051] like Figure 5 As shown, water-absorbing bristles 34 are provided on the inner edge of the groove body 151 and on the side away from the dust suction pipe 27. The purpose of providing the water-absorbing bristles 34 is to wipe off the residual water on the surface of the discharge pipe.

[0052] like Figure 4As shown, a discharge port 25 is provided at the bottom of the polishing cover 15 , and waste materials are discharged through the discharge port 25 .

[0053] Meanwhile, the contents not described in detail in this specification belong to the prior art known to the professional and technical personnel in this field.

[0054] When in use, first place the exhaust pipe (labeled a in the figure, the same below) on the grid mesh plate 5, and pass the exhaust pipe through the polishing groove 161. At this time, the surface of the exhaust pipe is pressed against the polishing belts 24 on the upper and lower sides to prepare for subsequent polishing.

[0055] Then it is necessary to fix the exhaust pipe on the clamping mechanisms 4 on both sides of the polishing table 1. According to the specific length of the exhaust pipe, the distance between the clamping mechanisms 4 is first adjusted so that the clamping mechanisms 4 can contact the inner wall of the exhaust pipe and can be clamped, and then the clamping mechanisms 4 are fixed in the current position by fixing bolts.

[0056] Then turn on the servo motor 42 to drive the driving gear 43 to rotate, and then the driving gear 43 can drive multiple clamps 44 on the periphery to rotate (turn outward), so that the multiple clamps 44 are firmly pressed against the inner wall of the exhaust pipe, thereby completing the fixation of the exhaust pipe, avoiding vibration and deviation of the exhaust pipe during the subsequent polishing process, and then avoiding scratches on the exhaust pipe.

[0057] Then, the first gear set 17 is driven to rotate by an external motor, and then the grinding wheel 16 is driven to rotate by the first belt 18, thereby driving the polishing belt 24 to perform a circular motion on the surface of the exhaust pipe to achieve the purpose of all-round polishing of the exhaust pipe.

[0058] Then, the first gear set 17 drives the second gear set 19 to rotate (in the opposite direction to increase the relative polishing speed), thereby driving the sleeve 20 to rotate with the help of the second belt 21, and then driving the pulley 22 to rotate through the third belt 23, and finally driving the polishing belts 24 on the upper and lower sides to rotate, thereby performing a full-scale polishing operation on the surface of the exhaust pipe.

[0059] During the polishing process, the polishing belt 24 needs to adjust its posture at any time to adapt to the current angle of the exhaust pipe. At this time, the third motor 14 is turned on to drive the entire polishing cover 15 to deflect, thereby driving the polishing belt 24 to deflect to adapt to the current polishing angle of the exhaust pipe. When the angle is adjusted, the first motor 8 and the second motor 12 are turned on respectively. By controlling the rotation speed of the first motor 8 and the second motor 12, the feed amount of the machine base 9 in the horizontal direction is controlled, so that the polishing belt 24 can move smoothly on the surface of the exhaust pipe in a facing posture and achieve polishing, thereby improving the polishing efficiency.

[0060] In summary, the polishing device for exhaust pipe processing replaces the traditional method of relying on manual control of the exhaust pipe by setting up an automatic feeding and conveying mechanism for the exhaust pipe. The automatic feeding and conveying mechanism can automatically adjust its own posture according to the specific shape of the exhaust pipe, thereby ensuring that during the entire polishing process, the polishing mechanism always maintains a parallel posture facing the exhaust pipe, so that various special-shaped turns on the exhaust pipe can be smoothly polished, greatly improving the polishing efficiency.

[0061] It should be noted that the electrical components appearing in this article are all connected to the external main controller and 220V or 380V mains electricity, and the main controller can be a conventional known device for controlling computers, etc. Its control principle, internal structure and control switch mode are all conventional means of the prior art, which are directly quoted here without further elaboration. In this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
