[0033] When in use, the metal tube is placed on the support seat 25, and then the metal tube is clamped and fixed by multiple clamping plates 2. The metal tube is protected by the rubber pad 30 provided on the clamping plate 2 during clamping to prevent the clamping plate 2 from causing wear to the metal tube during the clamping process. After the metal tube is clamped and fixed, the connecting plate 5 and the grinding block 6 on the connecting plate 5 are moved to the metal tube port through the linkage assembly. Since the connecting plates 5 and the grinding blocks 6 are provided at both ends of the metal tube, the ports at both ends of the metal tube can be polished at the same time, and the polishing efficiency is high. Before polishing, the position of the grinding block 6 can be adjusted to adapt to metal tubes of different diameters. The matching degree is high; and during grinding, the port is ground by multiple grinding blocks 6, and the multiple first suction holes 8, multiple second suction holes 9 and multiple third suction holes 10 set on the connecting plate 5 can timely suck away the waste chips generated during grinding, and the multiple first suction holes 8 can suck away the waste chips between the grinding block 6 and the port, and the multiple second suction holes 9 and multiple third suction holes 10 can suck away the waste chips between the connecting plate 5 and the grinding block 6, so that the waste chips at multiple positions can be cleaned, and the waste chips are prevented from causing wear to the metal pipe port and the waste chips are prevented from flying around, thereby realizing the cleaning and collection of the waste chips and improving the grinding quality of the metal pipe.

[0034] Specifically, refer to Figure 4 As shown, a dust suction pipe 11 is provided on the first block 4, and a second block 12 is provided at one end of the dust suction pipe 11 extending out of the first block 4.

A second hollow tube 15 is slidably provided in the first hollow tube 14, and one end of the second hollow tube 15 is connected to the first cavity 7 in the connecting plate 5.

[0035] When cleaning waste chips, the waste chips enter the first cavity 7 through multiple first suction holes 8, multiple second suction holes 9 and multiple third suction holes 10, and then enter the second cavity 13 through the second hollow tube 15 and the first hollow tube 14, and then the waste chips are cleaned and collected through the dust suction pipe 11; in this solution, the shape, size and arrangement density of the multiple first suction holes 8, multiple second suction holes 9 and multiple third suction holes 10 are set according to actual conditions, and this solution does not impose too many restrictions.

[0036] Specifically, refer to Figure 4 As shown, a boss 16 is provided outside the first hollow tube 14 , and a first spring 17 is provided outside the second hollow tube 15 between the boss 16 and the connecting plate 5 .

[0037] When the connecting plate 5 and the grinding block 6 move, the second hollow tube 15 is driven to move, and at the same time the first spring 17 is extended and contracted. The first spring 17 exerts a thrust on the connecting plate 5, so that the connecting plate 5 is always close to the inner wall of the metal tube during the grinding process, making it easier for the grinding block 6 to grind the end of the metal tube.

[0038] Specifically, refer to Figure 5 、 Figure 8 As shown, the linkage assembly includes a guide rod 18 symmetrically arranged on the support frame 3, a support plate 19 is slidably arranged on the guide rod 18, a ring plate 20 is rotatably arranged inside the support plate, the ring plate 20 is arranged on the outer circular surface of the dust suction pipe 11, and a cylinder 39 is arranged on the inner side of the support seat 25, and the output end of the cylinder 39 is connected to the support plate 19.

[0039] Start the cylinder 39. When the cylinder 39 is working, it drives the support plate 19 to move on the guide rod 18, and then drives the ring plate 20 and the dust suction pipe 11 to move together, and then drives the connecting plate 5 and the grinding block 6 to move, so that the grinding block 6 is located at the end of the metal pipe to realize the adjustment function; among them, the cylinder 39 is a prior art and will not be elaborated in detail in this solution.

When the transmission belt 23 rotates, it drives the first transmission wheel 21 to rotate, and then drives the dust suction pipe 11 to rotate, thereby driving the first block 4, the second block 12, multiple connecting plates 5 and multiple grinding blocks 6 to rotate at the same time. The metal pipe port is ground by the rotating multiple grinding blocks 6, which effectively improves the grinding efficiency of the metal pipe.

[0042] Specifically, refer to Figure 9 As shown, an annular cavity 26 is provided in the support seat 25, and a plurality of through cavities 27 connected with the annular cavity 26 are provided in the support seat 25.

[0043] When clamping and fixing, the air holes enter the annular cavity 26 and then enter the multiple through cavities 27, causing the pressure in the multiple through cavities 27 to increase, thereby pushing the multiple slides 28 and the clamping plates 2 on the slides 28 to move together, thereby achieving clamping and fixing of the metal tube; among them, the second spring 29 has the function of resetting the clamping plate 2.

[0044] Specifically, refer to Figure 9As shown, a third cavity 31 communicating with the annular cavity 26 is provided in the support seat 25 , an air pipe 32 is provided on the support seat 25 , a suction pump 33 is provided on the upper end surface of the support seat 25 , and the output end of the suction pump 33 is connected to the air pipe 32 .

[0045] Start the suction pump 33. When the suction pump 33 is working, the external gas enters the third cavity 31 through the air pipe 32, and then enters the multiple through cavities 27 through the annular cavity 26, so that the pressure in the multiple through cavities 27 becomes larger, thereby pushing the multiple slides 28 and the clamping plates 2 on the slides 28 to move together, thereby clamping and fixing the metal pipe; among them, the suction pump 33 is a prior art and will not be elaborated in detail in this solution.

[0046] Specifically, refer to Figure 3 、 Figure 8 As shown, a collecting box 34 is provided on the lower end face of the support frame 3, and a detachable inner box 35 is slidingly provided in the collecting box 34.

A suction pump 37 is provided on the lower end face of the support frame 3, and the suction pump 37 is connected to the collecting box 34 through a short pipe 38.

[0047] Start the suction pump 37. When the suction pump 37 is working, the waste chips enter the first cavity 7 through multiple first suction holes 8, multiple second suction holes 9 and multiple third suction holes 10, and then enter the second cavity 13 through the second hollow tube 15 and the first hollow tube 14. Then, the waste chips are sucked into the inner box 35 of the collection box 34 through the dust suction pipe 11 and the connecting pipe 36, completing the cleaning and collection of the waste chips. Subsequently, the inner box 35 can be disassembled and the waste chips therein can be cleaned. After cleaning, the inner box 35 can be reinstalled into the collection box 34 for subsequent use. The suction pump 37 is a prior art and will not be elaborated in detail in this solution.

[0048] Specifically, refer to Figure 4 As shown, an electronic telescopic rod 43 is provided on the first block 4 , and the output end of the electronic telescopic rod 43 is connected to the connecting plate 5 .

[0049] During adjustment, the electronic telescopic rod 43 is activated.

When the curved surface 44 on the connecting plate 5 contacts the inner wall of the metal pipe, it indicates that the connecting plate 5 and the grinding block 6 have been adjusted to the appropriate position, so that the device can grind metal pipes of different diameters. Among them, the electronic telescopic rod 43 is existing technology and will not be elaborated in detail in this solution.

[0050] Specifically, refer to Figure 3As shown, a first transmission rod 24 and a second transmission rod 40 are rotatably arranged in the base 1, a square rod 41 is arranged on the end surface of the second transmission rod 40, and the other end of the square rod 41 is slidingly connected to the first transmission rod 24, one of the second transmission wheels 22 is connected to the outer circular surface of the first transmission rod 24, and the other second transmission wheel 22 is connected to the outer circular surface of the second transmission rod 40, and a motor 42 is arranged in the base 1, and the output end of the motor 42 is connected to the first transmission rod 24.
