DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-5 A construction pipe welding device comprises a frame 1, a pair of movable blocks 3 are slidably connected to the top of the frame 1 through a guide groove 2, a fastener 4 for fixing the pipe is provided on the top of the movable block 3, and a control unit 5 and a welding frame 6 are provided next to the guide groove 2, a welding gun 61 is provided in the welding frame 6, an electric push rod is fixedly installed on the top of the inner wall of the welding frame 6, the output end of the electric push rod is fixedly connected to the welding gun 61, and the height of the welding gun 61 is changed by the electric push rod to facilitate welding.

[0025] The fastener 4 further includes a driving member 7 for driving the pipe to rotate, and a grinding assembly 8 for grinding the pipe is provided on the top of the frame 1.

[0026] Furthermore, a first motor 11 is fixedly installed on the side of the frame 1, the first motor 11 is electrically connected to the control unit 5, and its shaft end passes through the frame 1 and is fixedly connected to a double-headed screw rod 12 in the guide groove 2, and a pair of movable blocks 3 are respectively threadedly connected to the two ends of the double-headed screw rod 12. The first motor 11 drives the double-headed screw rod 12 to rotate, so that the pair of movable blocks 3 can move toward or away from each other, so that the pipe can be unloaded and loaded.

[0027] Furthermore, the fastener 4 includes a pair of support plates 41 fixedly installed on the top of the movable block 3, and the end faces of the pair of support plates 41 are rotatably connected to an air expansion shaft 43 through a connecting seat 42. The air expansion shaft 43 can press against the inner wall of the pipe. The air circuit of the air expansion shaft 43 is connected to an external air compressor. The air expansion shaft 43 is used to press against the inner wall of the pipe to achieve a fixing effect, which can prevent the pipe from moving during welding.

[0028] In more detail, a distance sensor 9 is fixedly mounted on the end surface of the support plate 41, and the distance sensor 9 is electrically connected to the control unit 5. A pair of gas expansion shafts 43 are provided with a recessed portion and a raised portion 44 at the facing ends thereof, respectively, and the raised portion 44 can be inserted into the recessed portion.

[0029] It is worth mentioning that when the protrusion 44 is inserted into the recessed portion, a pair of the gas expansion shafts 43 are fixed together, and then the second motor 71 is used to drive one of the gas expansion shafts 43, so that the two gas expansion shafts 43 can rotate at the same time. The advantage is that the rotation speed of a pair of pipes can be controlled to ensure stable welding, and the pipes can be driven to rotate to cooperate with the welding gun 61 for welding. In addition, the distance sensor 9 is used to determine whether a pair of pipes are in contact with each other or with the grinding wheel 87, and then the control unit 5 stops the rotation of the first motor 11.

[0030] In general, the driving member 7 includes a second motor 71 fixedly installed on the top of one of the movable blocks 3, the second motor 71 is electrically connected to the control unit 5, one end of the connecting seat 42 passes through the support plate 41 and is fixedly connected to the axial end of the second motor 71, and the second motor 71 cooperates with the connecting seat 42 to drive the pipe to rotate for welding.

[0031] In addition, the grinding assembly 8 includes a base 81, the top of the frame 1 is located between a pair of the air expansion shafts 43 and the base 81 is fixedly installed, and a cylinder 82 is fixedly installed on one side of the base 81, and a push block 83 is fixedly installed on the shaft end of the cylinder 82, and the push block 83 is slidably connected in the base 81.

[0032] Finally, an inclined groove 84 is provided at the top of the other side of the base 81, and a transverse plate 85 is rotatably connected to the top of the push block 83. Both sides of the transverse plate 85 are slidably connected in the inclined groove 84. A dual-axis motor 86 is fixedly installed on the end surface of the transverse plate 85, and grinding wheels 87 are fixedly installed on the two axis ends of the dual-axis motor 86. The grinding wheel 87 can grind the end surface and surface of the pipe.

[0033] It should be noted here that the push block 83 and the cross plate 85 are rotationally connected via a rotating shaft, and the cross plate 85 and the inclined groove 84 are slidingly connected via a round rod. The rotating shaft and the round rod are not concentric, and the height of the round rod is slightly lower than the rotating shaft, so that the cross plate 85 rotates upward when pushed by the push block 83.

[0034] It is worth mentioning that the grinding assembly 8 is arranged below the welding gun 61, that is, between a pair of the air expansion shafts 43. Before welding, the end faces and surfaces of a pair of pipes are ground by the grinding assembly 8. When preparing for welding, the axial end of the cylinder 82 contracts to drive the push block 83 to move backward. The push block 83 will also drive the cross plate 85 to move while moving. However, the cross plate 85 is constrained by the inclined groove 84 and will drive the dual-axis motor 86 to flip when moving, thereby freeing up operating space for the welding gun 61 to perform welding.

[0035] It should be supplemented that a grinding plate 871 is provided on the inner side surface of the grinding wheel 87, and a plurality of grooves 872 are arranged in a circular array on the inner wall. A grinding block 873 is slidably connected in the groove 872, and a spring 874 is fixedly connected between the groove 872 and the grinding block 873. The grinding plate 871 can contact the end of the pipe that needs to be polished, and the grinding block 873 can be pressed against the outer periphery of the pipe under the action of the spring 874, and then the pipe is polished under the drive of the dual-axis motor 86.

[0036] In addition, considering the existence of the protrusion 44 and the recessed portion, there is a certain distance between the grinding wheel 87 and the grinding plate 871, and an avoidance groove is opened at the center point of the grinding plate 871, and the avoidance groove is used to accommodate the protrusion 44 and the recessed portion.

[0037] Working method: When working, the pipe is sleeved on a pair of air expansion shafts 43, and the convex blocks on the air expansion shafts 43 are pressed against the inner wall of the pipe, and then the first motor 11 drives the double-headed screw 12 to drive a pair of movable blocks 3 to move toward each other. When the ends of a pair of pipes collide with the grinding wheel 87, the distance sensor 9 sends an electrical signal to the control unit 5 and then the first motor 11 stops rotating, and then the double-axis motor 86 drives the grinding wheel 87 to grind the pipe;

[0038] After grinding is completed, the dual-axis motor 86 stops rotating, and then drives the first motor 11 to reverse so that a pair of movable blocks 3 move away from the moving pipe and separate from the grinding wheel 87. Then, the axial end of the cylinder 82 contracts and drives the push block 83 to move backward. The push block 83 will also drive the cross plate 85 to move while moving, but the cross plate 85 is constrained by the inclined groove 84 and will drive the dual-axis motor 86 to flip when moving. Finally, the first motor 11 rotates again to drive a pair of movable blocks 3 to move toward each other, and the protrusion 44 is inserted into the recessed part to make a pair of pipes collide, and welding is performed under the action of the welding gun 61.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
