[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0031] Reference Figures 1 to 6 , which is the first embodiment of the present invention, provides a metal pipe welding method, by which the metal pipe can be polished immediately after welding is completed, thereby improving work efficiency.

[0032] First, clamp the metal pipe fittings, and then grind them after the metal pipe fittings are clamped. During the grinding process, the welding point can be cooled and waste chips can be collected; The surface of the metal pipe can be clamped by using the clamping mechanism 200. After welding, the metal pipe can be flipped over by the flipping assembly and then polished. During the polishing process, the welding part of the metal pipe can be cooled by using the pushing component 403.

[0033] Specifically, it is first clamped by the clamping mechanism 200 and then polished by the polishing assembly 301. During the polishing process, the temperature of the welding part of the metal pipe can be reduced.

[0034] Furthermore, the metal pipe is first clamped by the clamping mechanism 200, and then a rotational force is applied to the metal pipe by the main clamping wheel 203d, so that the metal pipe can be rotated during the welding process. After the welding of the metal pipe is completed, it can be flipped. After flipping, the metal pipe can be polished by the polishing component 301 and the welding point can be cooled during the polishing process.

[0035] It should be noted that the main clamping wheel 203d is electrically controlled and is used to rotate when welding metal pipes.

[0036] Reference Figures 1 to 4 6 is a second embodiment of the present invention, which provides a clamping mechanism 200 and a grinding mechanism 300 to enable the metal pipe to be ground after welding.

[0037] The clamping mechanism 200 is arranged on the right side of the main body 101, and the clamping mechanism 200 includes an output component 201, and two flip components 202 are arranged on the surface of the output component 201, and two clamping components 203 are arranged on the surfaces of the two flip components 202; the output component 201 includes a first fixed seat 201a, a first motor 201b and an output rod 201c, the left side of the first fixed seat 201a is fixedly installed on the right side of the main body 101, the outer surface of the first motor 201b is fixedly installed on the inner wall of the first fixed seat 201a, the right side of the output rod 201c is transmission-connected to the output end of the first motor 201b, and the left side of the output rod 201c penetrates into the interior of the main body 101.

[0038] Specifically, the surface of the metal pipe can be clamped before welding, and the metal pipe can be flipped by a flip assembly after welding.

[0039] Furthermore, when the metal pipe is placed on the surface of the arc rod 203e, the triangular plate 203c can be squeezed. After the triangular plate 203c is squeezed, the two clamping rods 203f can be driven to flip in opposite directions using the rotating column 203h. During the flipping process of the two clamping rods 203f, they are opened and torque is applied to the torsion spring 203i at the same time. Then a staff member pushes the metal pipe to the opposite side of the two clamping rods 203f, and then the metal pipe can be clamped by releasing the torsion spring 203i.

[0040] The grinding mechanism 300 is arranged on the front side of the main body 101, and the grinding mechanism 300 includes a grinding assembly 301. The opposite side of the grinding assembly 301 is provided with a rotating component 302; the grinding assembly 301 includes a fixed frame 301a, a main fixed plate 301b, a main grinding ring 301c, a water hole 301d, a discharge hole 301e and an auxiliary grinding ring 301f. The rear side of the fixed frame 301a is fixedly installed on the front side of the main body 101, the outer side of the main fixed plate 301b is the inner wall of the fixed frame 301a, the main grinding ring 301c is arranged on the top of the main fixed plate 301b, the water hole 301d is opened inside the main grinding ring 301c, the discharge hole 301e is opened inside the main fixed plate 301b, and the auxiliary grinding ring 301f is arranged on the rear side of the main grinding ring 301c.

[0041] Specifically, after the metal pipe is turned over, the welding position thereof can be polished by the transportation of the second motor 302c.

[0042] Furthermore, after the metal pipe is turned over, the arc rod 203e can be used to squeeze the auxiliary clamping ring 302h. After the auxiliary clamping ring 302h is squeezed, the spring 302m can be given a squeezing force to move to the right. While the auxiliary clamping ring 302h is squeezed, the arc rod 203e can use the travel rod 302l to move on the surface of the travel groove 302k, so that the metal pipe is released from the clamp and falls on the top of the main fixing plate 301b and the auxiliary fixing plate 302a. When the metal pipe falls on the top of the main fixing plate 301b and the auxiliary fixing plate 302a, the first motor Rotation in the direction of 201b can reset the clamping assembly, so that the metal pipe can be clamped again by the rebound force of the spring 302m, and then the staff can use the controller to start the second motor 302c. The operation of the second motor 302c can drive the main pulley 302e to rotate by using the belt to drive the secondary pulley 302f, and the rotation of the secondary pulley 302f can drive the metal pipe to rotate. Since the surface of the metal pipe fits with the main grinding ring 301c and the secondary grinding ring 301f, the metal pipe can be polished during its rotation.

[0043] It should be noted that the auxiliary grinding ring 301f and the auxiliary clamping ring 302h move synchronously.

[0044] Reference Figure 1 , 3 5 is a third embodiment of the present invention, which provides a collection mechanism 400 to collect waste chips and cool the grinding area when grinding metal hangers.

[0045] The collecting mechanism 400 is arranged on the front side of the grinding mechanism 300, and the collecting mechanism 400 includes a collecting component 401. The bottom of the collecting component 401 is provided with a knocking component 402 and a pushing component 403. The collecting component 401 includes a collecting box 401a, a pull-out plate 401b, two pull-out grooves 401c, two pull-out rods 401d and a filter 401e. The collecting box 401a is arranged inside the fixed frame 301a and is located at the bottom of the main fixed plate 301b. The right side of the pull-out plate 401b is arranged on the left side of the collecting box 401a. The two pull-out grooves 401c are both opened on the inner wall of the collecting box 401a. The surfaces of the two pull-out rods 401d are slidably connected to the surfaces of the two pull-out grooves 401c. The left sides of the two pull-out rods 401d are fixedly installed on the right side of the pull-out plate 401b, and the opposite side of the filter 401e is fixedly installed on the opposite side of the two pull-out rods 401d.

[0046] Specifically, during the grinding process of the metal pipe, the water pipe 403f can be used to cool it down, and the waste chips generated during the grinding can be collected by the collection component 401.

[0047] Furthermore, during the rotation of the second motor 302c, the main gear 302d can be used to drive the sub-gear to rotate at the same time, and the rotation of the sub-gear can drive the push rod 403a to move, and when the push rod 403a moves, the L-shaped toothed plate 403c can be driven to move. Since the L-shaped toothed plate 403c is meshed with the first gear 402d, the L-shaped toothed plate 403c can drive the first gear 402d to rotate when it moves, and the rotation of the first gear 402d can make the knocking rod 402e knock on the concave plate 402a, and when the concave plate 402a is knocked, the knocking column 402c is used to knock on the filter screen 401e, so that the waste debris is knocked and vibrates on the surface of the filter screen 401e, causing the water source to flow out, and during the movement of the push rod 403a, the push plate 403e can also be driven to move, and the water source can be pushed to the inside of the water pipe 403f for spraying through the movement of the push plate 403e.

[0048] The remaining structure is the same as that of Example 2.

[0049] Reference Figures 1 to 6 , which is the fourth embodiment of the present invention. This embodiment is different from the third embodiment in that: this embodiment provides a metal pipe welding device.

[0050] When using the device, the metal pipe is first placed on the surface of the arc rod 203e to squeeze the triangular plate 203c. After the triangular plate 203c is squeezed, the two clamping rods 203f can be driven to flip in opposite directions using the rotating column 203h. During the flipping process of the two clamping rods 203f, they are opened and the torsion spring 203i is applied with torque. Then, a worker pushes the metal pipe to the opposite side of the two clamping rods 203f. Then, the metal pipe can be clamped by releasing the torsion spring 203i. After the clamping is completed, welding is performed. After welding is completed, the metal pipe is turned over by rotating the first motor 201b in the direction of rotation. After the metal pipe is turned over, the arc rod 203e can be used to squeeze the auxiliary clamping ring 302h. After the auxiliary clamping ring 302h is squeezed, the spring 302m can be given an extrusion force to move rightward. While the auxiliary clamping ring 302h is squeezed, the arc rod 203e can use the travel rod 302l to move on the surface of the travel groove 302k, so that the metal pipe is released from the clamp and falls on the top of the main fixing plate 301b and the auxiliary fixing plate 302a. When the metal pipe falls onto the top of the main fixing plate 301b and the auxiliary fixing plate 302a, the reverse rotation of the first motor 201b can reset the clamping component 203, so that the metal pipe can be clamped again by the rebound force of the spring 302m, and then the staff can start the second motor 302c by using the controller, and the operation of the second motor 302c can drive the main pulley 302e to rotate by using the belt to drive the auxiliary pulley 302f, and the rotation of the auxiliary pulley 302f can drive the metal pipe to rotate. 01c and the auxiliary grinding ring 301f are fitted together, so that the metal pipe can be ground during its rotation. During the rotation of the second motor 302c, the main gear 302d can be used to drive the auxiliary gear 302d-1 to rotate, and the rotation of the auxiliary gear 302d-1 can drive the push rod 403a to move. When the push rod 403a moves, the L-shaped toothed plate 403c can be driven to move. Since the L-shaped toothed plate 403c is meshed with the first gear 402d, the L-shaped toothed plate 403c can drive the first gear 40 2d rotates, and the rotation of the first gear 402d can make the knocking rod 402e knock on the concave plate 402a, and when the concave plate 402a is knocked, the knocking column 402c is used to knock on the filter screen 401e, so that the waste chips are vibrated on the surface of the filter screen 401e after being knocked, so that the water source flows out, and in the process of the movement of the pushing rod 403a, the pushing plate 403e can also be driven to move, and the water source can be pushed to the inside of the water pipe 403f for spraying through the movement of the pushing plate 403e, so as to spray water to cool the polished part of the metal pipe.

[0051] In summary: the concave plate 402a and the isolation plate 403d are both plates that can be used for flowing water.
