DETAILED DESCRIPTION

[0033] 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.

[0034] like Figures 1 to 8 As shown, the present invention provides a stabilizing device for copper tube processing, comprising a bottom plate 1, and further comprising:

[0035] A grinding assembly 2, which is fixed on the top of the bottom plate 1, one end of which is used for grinding the copper tube flaring, and the other end of which is used for grinding the outside of the copper tube;

[0036] The stabilizing assembly 4 is arranged at both ends of the top of the bottom plate 1 and located on both sides of the grinding assembly 2, and the stabilizing assembly 4 and the grinding assembly 2 are kept level;

[0037] A cleaning component 3, which is fixed on the top of the bottom plate 1 and sleeved on the outside of the grinding component 2 to collect dust generated by grinding the copper tube;

[0038] The grinding assembly 2 includes a transmission wheel 21 mounted on the top of the bottom plate 1. The outside of the transmission wheel 21 is connected to the driving device through a transmission belt 24. An inner grinding wheel 23 and an outer grinding wheel 26 are fixed on both sides of the transmission wheel 21. The outer annular array of the inner grinding wheel 23 has a grinding sandpaper 1 25, and the inner wall annular array of the outer grinding wheel 26 has a grinding sandpaper 2 27. The outer diameter of the inner grinding wheel 23 gradually increases from the inside of the pipe mouth to the outside.

[0039] The stabilizing assembly 4 includes a fixing plate 46 fixed to the top of the bottom plate 1, a guide block 47 is fixed to the top of the fixing plate 46, a support frame 45 is slidably engaged with the top of the guide block 47, two stabilizing frames 41 for stabilizing the copper tube are arranged on the support frame 45, and protrusions 48 for limiting the support frame 45 are arranged at both ends of the top of the guide block 47. The two stabilizing frames 41 are hinged and one of the stabilizing frames 41 is fixedly connected to the support frame 45. The inner walls of one end of the two stabilizing frames 41 are respectively provided with arc guide grooves 42, and the depth of the arc guide grooves 42 changes from deep to shallow. Stabilizing pads 43 made of rubber material are respectively arranged inside the arc guide grooves 42, and the inner walls of the stabilizing pads 43 are uneven, and the other ends of the two stabilizing frames 41 are connected with springs 44.

[0040] The air pressure generated by the cleaning component 3 pushes the other end of the stabilizing frame 41 to stretch the spring 44. Since the spring 44 and the two stabilizing frames 41 are connected in a ball-shaft manner, the stabilizing frame 41 can rotate normally. The openings at one end of the two stabilizing frames 41 gradually increase, and the two copper tubes that need to be connected can be placed at one end of the stabilizing frame 41, and the inner wall of the stabilizing pad 43 is in contact with the outside of the copper tube. The other end of the stabilizing frame 41 is released and reset by the spring 44, and the copper tube is clamped and fixed by the two stabilizing frames 41.

[0041] The copper tube is fixed in two stabilizing components 4, and the air pressure generated by the cleaning component 3 pushes the two support frames 45 to move relative to each other along the surface of the guide block 47. During the movement, the driving device and the transmission belt 24 drive the transmission wheel 21, the grinding sandpaper 1 25, the inner grinding wheel 23, the outer grinding wheel 26 and the grinding sandpaper 2 27 to rotate. At the same time, the sheathed copper tube is gradually sheathed inside the outer grinding wheel 26, and the copper tube that needs to be expanded is gradually sheathed outside the grinding sandpaper 1 25. During the copper tube sheathing process, the outer part of the sheathed copper tube is polished by the grinding sandpaper 27, and the copper tube that needs to be expanded pushes the two support frames 45 and the two copper tubes to move relative to each other along the surface of the guide block 47 under the action of the cleaning component 3, and is gradually sheathed outside the inner grinding wheel 23. The purpose of expanding the opening is achieved. In this process, the inner wall is polished by the grinding sandpaper 25. During the grinding process, the mesh number of the grinding sandpaper 27 and the inner grinding wheel 23 is gradually increased, so that the effect of copper tube grinding is better. Since the inner grinding wheel 23 and the outer grinding wheel 26 continuously rotate to grind and expand the copper tube, the copper tube generates a rotating force in the same direction, and the outer part of the copper tube contacts the inner wall of the stabilizing pad 43. The copper tube will drive the stabilizing pad 43 to move along the circular arc guide groove 42. Since the depth of the circular arc guide groove 42 gradually becomes shallower, the stabilizing pad 43 gradually protrudes from the inner wall of the stabilizing frame 41, thereby reducing the inner diameter of one end of the stabilizing frame 41, increasing the squeezing force on the copper tube, and thus preventing the copper tube from rotating during the grinding process to affect the effect of copper tube grinding;

[0042] It is explained here that the inner grinding wheel 23 and the outer grinding wheel 26 can be replaced according to the diameter of the copper tube, so that they can meet the needs of processing different copper tubes.

[0043] The present application also includes: after the copper tube butt-end processing is completed, the grinding component 2 and the stabilizing component 4 are separated and kept horizontal, and then the two stabilizing components 4 are pushed to move in the same direction so that the two copper tubes are butt-jointed, and welding processing can be performed, while ensuring the stability of the copper tube welding, thereby ensuring the quality of the welding.

[0044] like Figure 2 , Figure 3 and Figure 5 As shown, the inner diameter of the outer grinding wheel 26 decreases from the pipe mouth to the inside, and the mesh numbers of the grinding sandpaper 1 25 and the grinding sandpaper 2 27 gradually increase from the outer end to the opposite end.

[0045] The outer diameter of one end of the inner grinding wheel 23 is larger than the inner diameter of the outer grinding wheel 26 , the outer diameter of the other end of the inner grinding wheel 23 is smaller than the inner diameter of the copper tube, and the inner diameter of one end of the outer grinding wheel 26 is larger than the outer diameter of the copper tube.

[0046] The two copper tubes to be butted are fixed on the two stabilizing components 4 respectively, and the air pressure generated by the cleaning component 3 pushes the two stabilizing components 4 and the copper tubes to move relative to each other, so that the copper tube at one end is sleeved on the outside of the inner grinding wheel 23, and the inner grinding wheel 23 is used to expand the opening to avoid the expansion diameter being too large or too small, which affects the butt connection of the copper tubes. At the same time, the inner wall of the copper tube is polished by the grinding sandpaper 25 outside the inner grinding wheel 23. During the polishing process, the copper tube is gradually sleeved on the outside of the inner grinding wheel 23, and the inner wall is polished from coarse to fine by the grinding sandpaper 25, thereby improving the polishing effect of the copper tube. The other copper tube enters the inner part of the outer grinding wheel 26 through one end of the outer grinding wheel 26, and the outer periphery is polished by the grinding sandpaper 27 to improve the stability of the copper tube butt connection.

[0047] like Figure 2 , Figure 6-Figure 8 As shown, two connecting rings 221 are sleeved at both ends of the outer periphery of the transmission wheel 21, a gathering pipe 222 is connected between the two connecting rings 221, and a cleaning hole 22 is opened in an annular array outside the transmission wheel 21;

[0048] The transmission belt 24 is sleeved on the outside of the transmission wheel 21 , and the transmission belt 24 blocks half of the cleaning holes 22 on the periphery of the transmission wheel 21 , while the gathering pipe 222 is connected to the inside of the transmission wheel 21 through the other half of the cleaning holes 22 .

[0049] The cleaning assembly 3 includes a collection box 31 fixedly mounted on the top of the bottom plate 1, the collection box 31 is connected to the collection pipe 222, a diversion box 32 is fixedly mounted on the top of the collection box 31, and a fan 33 is fixedly mounted on the side of the diversion box 32;

[0050] The air inlet of the fan 33 is connected to the collecting box 31, and the air outlet of the fan 33 is connected to the diverter box 32;

[0051] The grinding assembly 2 further includes a stabilizing rod 211 movably mounted in the middle of the transmission wheel 21, and blocking blocks 212 of the same specifications are movably mounted at both ends of the stabilizing rod 211;

[0052] The inner wall of the transmission wheel 21 is provided with through grooves in an annular manner on both sides, and the outer ends of the through grooves are kept level with the inner walls of the inner grinding wheel 23 and the outer grinding wheel 26;

[0053] The copper tube is sleeved outside the inner grinding wheel 23, and a blocking block 212 at one end contacts the inner wall of the copper tube. The two blocking blocks 212 are replaced according to the inner diameter of the copper tube.

[0054] A copper tube is sleeved inside the outer grinding wheel 26, and the block 212 at the other end contacts the inner wall of the copper tube to block the copper tube, and one end of the copper tube coincides with the through groove, thereby preventing the copper tube from contacting the side of the transmission wheel 21, and the outer grinding wheel 26 drives the grinding sandpaper 27 to rotate to grind the outer periphery of the copper tube, and the other end of the copper tube is sleeved outside the inner grinding wheel 23 and the block 212 at one end blocks the inner wall of the copper tube, and the inner wall is polished by the grinding sandpaper 25. During the grinding process, the fan 33 is used to extract air from the collection box 31, the gathering pipe 222 and the inside of the transmission wheel 21, and the transmission belt 24 drives the transmission wheel 2 During the rotation, the transmission belt 24 always blocks half of the cleaning hole 22, the connecting ring 221 is movably sleeved on the outside of the transmission wheel 21, the gathering pipe 222 is always connected with the inside of the transmission wheel 21 through the other half of the cleaning hole 22, and the two blocking blocks 212 respectively block the inner walls of the two pipes. At this time, the gas enters the inner grinding wheel 23 and the transmission wheel 21 through the gap between the grinding sandpaper 1 25, and the gas at the other end will pass through the gap between the grinding sandpaper 2 27 and enter the transmission wheel 21 through the through groove. The gas will carry dust generated by the grinding of the copper tube during the process of entering, and the dust will be sucked into the collection box 31 for storage and regular cleaning.

[0055] like Figure 1 and Figure 3 As shown, two ends of the diverter box 32 are respectively connected with butt-joint pipes 34 , and the other end of the butt-joint pipe 34 is corrugated and connected to the support frame 45 .

[0056] Air is sucked from the collection box 31 through the fan 33 and injected into the diversion box 32, and then enters the two docking tubes 34 respectively. The pressure in the docking tubes 34 gradually increases, pushing the two support frames 45 to move relative to each other along the surface of the guide block 47, and driving the copper tube sleeve to be disposed outside the grinding assembly 2 for processing.

[0057] The working principle and use process of the present invention:

[0058] By pushing the stabilizing frame 41 to stretch the spring 44, the spring 44 is connected between the two stabilizing frames 41 through the ball shaft, so that the stabilizing frame 41 can rotate normally, and the opening at one end of the two stabilizing frames 41 is gradually enlarged, so that the two copper tubes that need to be butted can be placed on one end of the stabilizing frame 41, and the inner wall of the stabilizing pad 43 is in contact with the outside of the copper tube, and the spring 44 at the other end of the stabilizing frame 41 is released to reset, so that the two stabilizing frames 41 can clamp and fix the copper tube, and the air is sucked from the collecting box 31 by the fan 33 and injected into the inside of the shunt box 32, and enters the two butt joint pipes 34 respectively, and the pressure in the butt joint pipes 34 gradually increases, pushing the two support frames 45 to move relative to each other along the surface of the guide block 47;

[0059] The driving belt 24 is driven by the driving device to drive the driving wheel 21, the grinding sandpaper 1 25, the inner grinding wheel 23, the outer grinding wheel 26 and the grinding sandpaper 2 27 to rotate, and the sheathed copper tube is gradually sheathed inside the outer grinding wheel 26, and the copper tube that needs to be expanded is gradually sheathed outside the grinding sandpaper 1 25. During the sheathing process of the sheathed copper tube, the outside of the sheathed copper tube is polished by the grinding sandpaper 27, and the copper tube that needs to be expanded is gradually sheathed outside the inner grinding wheel 23 under the action of the cleaning component 3 to achieve the purpose of expansion. In this process, the inner wall is polished by the grinding sandpaper 1 25, and the grinding sandpaper is polished during the grinding process. The mesh numbers of the second sandpaper 27 and the grinding sandpaper 25 are gradually increased, so that the grinding effect of the copper tube is better. Since the inner grinding wheel 23 and the outer grinding wheel 26 continuously rotate to grind and expand the copper tube, the copper tube generates a rotation force in the same direction, and the outer part of the copper tube contacts the inner wall of the stabilizing pad 43. The copper tube will drive the stabilizing pad 43 to move along the circular arc guide groove 42. Since the depth of the circular arc guide groove 42 gradually becomes shallower, the stabilizing pad 43 gradually protrudes from the inner wall of the stabilizing frame 41, thereby reducing the inner diameter of one end of the stabilizing frame 41, increasing the squeezing force on the copper tube, and thus preventing the copper tube from rotating during the grinding process;

[0060] During the copper tube grinding process, air is extracted from the collection box 31, the gathering pipe 222 and the transmission wheel 21 through the fan 33. When the transmission belt 24 drives the transmission wheel 21 to rotate, the transmission belt 24 always blocks half of the cleaning holes 22. The connecting ring 221 is movably sleeved on the outside of the transmission wheel 21. The gathering pipe 222 is always connected with the inside of the transmission wheel 21 through the other half of the cleaning holes 22. The two blocking blocks 212 respectively block the inner walls of the two pipes. At this time, the gas enters the inner grinding wheel 23 and the transmission wheel 21 through the gap between the grinding sandpaper 1 25, and the gas at the other end will pass through the gap between the grinding sandpaper 27 and penetrate the through groove into the transmission wheel 21. The gas will carry dust generated by the copper tube grinding during the entry process. The dust will be extracted into the collection box 31 for storage and cleaned regularly.
