[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] Two symmetrically distributed drive components 7 are fixedly installed on the left and right sides of the upper end of the base 1.

At the same time, the drive component 7 can also push the processed metal pipe forward, thereby realizing the loading and unloading operations of the metal pipe without manual operation;

[0034] A clamping assembly 8 is fixedly installed on the front side of the middle part of the upper end of the base 1. The clamping assembly 8 can cooperate with the driving assembly 7 to clamp metal pipes of different sizes. When the clamping assembly 8 clamps the metal pipe, it will not affect the rotation and grinding of the metal pipe.

[0035] A material storage component 9 is fixedly installed in the middle of the lower end of the base 1, and a friction component 10 is fixedly installed on the left side of the upper front end of the base 1. The friction component 10 can be pressed on the surface of metal pipes of different sizes, and then the surface of the metal pipe is rubbed to drive the metal pipe to rotate, thereby improving the versatility of the device;

[0036] A sharpening knife 11 is fixedly connected to the front right side of the upper end of the base 1, a guide groove 2 12 is opened on the left and right sides of the upper end of the base 1, and a guide groove 3 13 is opened on the left and right sides of the upper end of the base 1, and the two guide grooves 3 13 are respectively located on the inner side of the guide groove 2 12 on the same side.

[0037] Embodiment 2: Based on Embodiment 1, this embodiment is for achieving the purpose of supporting the inner walls of metal tubes with different inner diameters.

[0038] For details, see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The feeding assembly 6 includes a connecting plate 61 fixedly connected to the middle part of the rear side of the upper end of the base 1, the connecting plate 61 is located on the front side of the mounting platform 3, a connecting rod 62 is rotatably connected to the middle part of the front end of the connecting plate 61, a reciprocating threaded rod 63 is fixedly connected to the front end of the connecting rod 62, and a guide rod 64 is fixedly connected to the upper and lower parts of the front end of the connecting plate 61, and the two guide rods 64 are respectively located on the upper and lower sides of the connecting rod 62, and a support assembly 65 is slidably installed on the outer surfaces of the two guide rods 64.

[0039] Furthermore, the support assembly 65 includes a hollow cylinder 651, the inner surface of the hollow cylinder 651 is threadedly connected to the outer surface of the reciprocating threaded rod 1 63, the upper and lower sides of the middle part of the front end of the hollow cylinder 651 are provided with a limit groove 652 that penetrates the hollow cylinder 651, and the two guide rods 64 are slidably connected to the inner cavities of the two limit grooves 652 respectively, and the left and right sides of the outer surface of the hollow cylinder 651 are provided with a cylindrical groove 653, and the inner surfaces of the two cylindrical grooves 653 are slidably connected with a guide column 1 654, and the two guide columns 1 654 are fixedly connected at one end located on the outside with an arc The two curved plates 1 655 and the hollow cylinder 651 are both fixedly connected with a spring 1 656 on one side close to each other. The two springs 1 656 are respectively located on the outside of the guide column 1 654 on the same side. The outer surfaces of the two curved plates 1 655 are both rotatably connected with a plurality of ball bearings 1 657 distributed in a matrix. The left and right sides of the front end of the hollow cylinder 651 are both fixedly connected with a curved plate 2 658. The front surfaces of the two curved plates 2 658 are both fixedly connected with a curved spring piece 659. The outer surfaces of the two curved plates 2 658 are slidably connected with a ring 650.

[0040] The inner wall of the metal tube is inserted from the outside of the two arc plates 655. During the insertion process, the two arc spring pieces 659 are squeezed and contracted by the inside of the metal tube until the front edge of the metal tube is aligned with the front edge of the hollow tube 651. When the metal tube is inserted, the plurality of balls 657 rotatably connected on the surfaces of the two arc plates 655 rotate along the insertion direction, and the two arc plates 655 squeeze the corresponding guide posts 654 inward according to the different inner diameters of the inner wall of the metal tube. Then, the guide posts 654 on the same side slide into the cylindrical grooves 653 on the same side. At the same time, the arc plates 655 on the same side squeeze and contract the springs 656 on the same side. The springs 656 on both sides continuously release pressure to the outside, so that the arc plates 655 on both sides always fit the inner wall of the metal tube with the plurality of balls 657 rotatably connected on their surfaces.

[0041] When the pipeline needs to be driven to move forward and backward in the future, when the connecting rod 62 rotates, the connecting rod 62 can drive the reciprocating threaded rod 1 63 fixed thereto to rotate, and the inner surface of the hollow cylinder 651 is threadedly connected to the outer surface of the reciprocating threaded rod 1 63, and the two guide rods 64 are respectively slidably connected to the two limiting grooves 652 opened at the front end of the hollow cylinder 651. Therefore, the two guide rods 64 play a role of limiting and guiding under the action of the two limiting grooves 652, and the arc-shaped spring piece 659 can push the front end of the metal pipe, so as to push the metal pipe backward. When the metal pipe needs to be taken out in the future, it is only necessary to push the circular ring 650 slidably connected to the surfaces of the two arc plates 2 658 backward, so that the circular ring 650 squeezes and contracts the arc-shaped spring piece 659 and no longer resists the front end of the metal pipe, and then the metal pipe can be taken out.

[0042] Therefore, the feed assembly 6 provided in this solution can support the inner wall of the metal tube, and can also drive the metal tube to move forward without affecting the normal processing rotation of the metal tube.

[0043] Embodiment 3: Based on Embodiment 2, this embodiment is for the purpose of assisting in fixing and centering the metal tube during processing.

[0044] For details, see Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 and Fig.10 The two driving components 7 include two threaded hole columns 71 fixedly connected to the left side of the upper end of the base 1. The two threaded hole columns 71 are respectively located at the front and rear sides of the guide groove 12 on the same side. The inner surfaces of the two threaded hole columns 71 are connected to a reciprocating threaded rod 72 for rotation together. The front end of the reciprocating threaded rod 72 is fixedly connected to a bevel gear 73. The outer surface of the reciprocating threaded rod 72 is threadedly connected to a pusher component 74.

[0045] Furthermore, the clamping assembly 8 includes two hollow rods 81 fixedly connected to the front of the upper end of the base 1, the two hollow rods 81 are symmetrically distributed on the left and right, the outer surfaces of the two hollow rods 81 are rotatably connected to the reciprocating threaded rods 3 82, the ends of the two reciprocating threaded rods 3 82 that are away from each other are fixedly connected to the bevel gear 2 83, the outer surfaces of the two reciprocating threaded rods 3 82 are threadedly connected to the hollow threaded cylinders 84, the lower parts of the outer surfaces of the two hollow threaded cylinders 84 are provided with guide grooves 1 85, the upper end of the base 1 is fixedly connected to two rectangular rods 86 that are symmetrically distributed on the left and right, the upper ends of the two rectangular rods 86 are respectively slidably connected to the inner cavities of the guide grooves 1 85 on the same side, and the ends of the two hollow threaded cylinders 84 that are close to each other are fixedly connected to the arc plate 3 87. Three circular holes distributed in a linear array are opened at the front and rear parts of the side where the two arc plates three 87 are close to each other. The inner surfaces of the six circular holes on the same side are slidably connected with guide pillars two 88. An arc plate four 89 is provided on the side where the two arc plates three 87 are close to each other. The six guide pillars two 88 on the same side are respectively fixedly connected with the arc plates four 89 on the same side. The arc plates four 89 on the same side and the side where the arc plates three 87 are close to each other are commonly fixedly connected with six springs two 80. The six springs two 80 on the same side are respectively located on the outside of the guide pillars two 88 on the same side. A plurality of ball bearings two 801 are rotatably connected in a matrix distribution on the side where the two arc plates four 89 are close to each other. The bevel gear two 83 on the same side is meshed with the bevel gear one 73 on the same side.

[0046] Furthermore, the rear ends of the connecting rod 62 and the two reciprocating threaded rods 72 are fixedly connected with transmission rods, and the outer surfaces of the three transmission rods are connected through pulleys and belt transmissions. The transmission rod located at the rear end of the connecting rod 62 passes through the connecting plate 61 and is fixedly connected to the front end of the motor 4 through a coupling.

[0047] It can be seen from the above that the rear end of the connecting rod 62 and the rear end of the two reciprocating threaded rods 72 are fixedly connected with a transmission rod, and the outer surfaces of the three transmission rods are connected by pulleys and belt transmission. The transmission rod located at the rear end of the connecting rod 62 passes through the connecting plate 61 and is fixedly connected to the front end of the motor 4 through a coupling. Therefore, when the motor 4 is started, under the action of the pulley and belt transmission connection, the connecting rod 62 and the two reciprocating threaded rods 72 can be rotated at the same time, and when the two reciprocating threaded rods 72 rotate, the two reciprocating threaded rods 72 will drive the bevel gear 73 fixedly connected thereto to rotate, and it can be seen from the above that the bevel gear 73 on the same side is meshed with the bevel gear 83 on the same side, so when the bevel gear 73 on both sides rotates, the bevel gears 83 on both sides can be driven to rotate at the same time;

[0048] When the bevel gears 83 on both sides rotate, the bevel gears 83 on both sides can drive the reciprocating threaded rods 82 fixedly connected thereto to rotate in the inner cavities of the corresponding hollow rods 81. Since the hollow threaded cylinder 84 on the same side is threadedly connected to the reciprocating threaded rods 82 on the same side, and the rectangular rod 86 is slidably connected to the guide grooves 85 provided at the lower part of the outer surface of the hollow threaded cylinder 84, it plays a role of limiting. As a result, when the reciprocating threaded rods 82 on both sides rotate, the hollow threaded cylinders 84 on both sides move inward at the same time, and then the hollow threaded cylinders 84 on both sides drive the arc plates 87 fixedly connected thereto to move inward at the same time. In the process of the arc plates 87 on both sides moving inward at the same time, the arc plates 89 on both sides are It will gradually fit to the outer wall of the metal tube. During the fitting process, the arc plate 4 89 on the same side will directly squeeze the spring 2 80 and the guide column 2 88 on the same side, so that the spring 2 80 on the same side will shrink and the guide column 2 88 will slide outward from the circular hole on the same side. However, after being compressed, the spring 2 80 on the same side will always release the pressure inward, so that the arc plate 4 89 will always fit to the outer wall of the metal tube. When the metal tube moves forward and backward, since the inner surfaces of the arc plates 4 89 on both sides are rotatably connected with a plurality of ball bearings 2 801, the normal movement of the metal tube during processing will not be affected. Moreover, under the clamping action of the arc plates 4 89 on both sides, the metal tube can be kept in the middle position to avoid deviation during the initial processing.

[0049] The effects of the two reciprocating threaded rods 72 shown in the figure are for reference only, and the actual appearance and shape are adjusted according to production requirements;

[0055] According to the second embodiment, after the metal tube is inserted, the support plate 102 can be lifted, and then the support plate 102 can be loosened, so that the support plate 102 drives the lower side of the friction roller 105 to always fit the surface of the metal tube under the force of the contraction of the arc spring 103, and then the motor 2 106 is started, so that the output end of the motor 2 106 drives the friction roller 105 fixedly connected thereto to rotate through the coupling, so that the friction roller 105 continuously rubs the surface of the metal tube, driving the metal tube to rotate;

[0056] When the metal pipe rotates and moves forward and backward, the cutting depth of the grinding knife 11 can be adjusted to achieve the desired grinding effect.

[0057] When the two reciprocating threaded rods 72 rotate, the threaded ring 741 on the same side is threadedly connected to the reciprocating threaded rod 72 on the same side, and the limiting plate 744 on the same side is slidably connected to the inner surface of the guide groove 12 on the same side, and the limiting plate 1 743 on the same side is slidably connected to the inner surface of the guide groove 13 on the same side. Therefore, when the two reciprocating threaded rods 72 rotate, the guide groove 12 and the guide groove 13 on the same side play a role of limiting and guiding. Then, the threaded ring 741 on the same side will drive the threaded ring 741 to move forward, so that the two push plates 742 move forward at the same time, touch the rear end of the metal pipe, and push the metal pipe out.

[0058] As can be seen from the above, the left and right ends of the push plate 95 are fixedly connected to the L-shaped rod 745 on the same side, and the L-shaped rod 745 on the same side is slidably connected to the inner surface of the slide groove 94 on the same side. Therefore, when the second limit plate 744 moves forward and backward with the threaded ring 741, the second limit plate 744 will drive the L-shaped rod 745 fixed thereto to move forward and backward at the same time, so that the two L-shaped rods 745 slide in the inner cavity of the slide groove 94 on the same side and drive the push plate 95 to slide on the upper end of the bottom plate 92. When the push plate 95 moves forward, the debris generated during grinding will be pushed forward, and when it moves backward, the debris will be pushed backward;

[0059] Therefore, it is sufficient to place a storage box for receiving the debris on the front and rear sides of the lower end of the bottom plate 92;

[0060] The grinding knife 11 mentioned above is a conventional setting in the prior art, which only needs to meet the grinding of the metal pipe and can be adjusted according to the grinding depth. Its specific installation method and shape characteristics can be adjusted according to actual production needs, so this solution will not be elaborated in detail;

[0061] The elastic force of the two springs 1 656 and the six springs 2 80 mentioned above is greater than the resistance of the grinding knife 11 to the workpiece during processing, and the grinding process only removes a thin layer of the pipeline surface and does not exert a large resistance on the pipeline, so the pipeline will not deviate during processing.

[0062] It should be noted that the specific installation method of the motor 1 4 and the motor 2 106 used in the present invention, the circuit connection method and the control method are all conventional designs and will not be elaborated in detail in the present invention.
