A positioning push plate 37 is slidably sleeved on the outer ring of the supporting crossbar 36, and a second spring 35 is fixedly installed between the positioning push plate 37 and the positioning base frame 34. The guiding inclined plates in the square holes inside the workbench 38 are located on both sides of the screw rod 30, so as to prevent welding slag from falling on the screw rod 30;

[0043] When the fifth gear 32 rotates, it can drive the second rack 33 to move toward one end close to the workbench 38 , so that the alignment push plate 37 can fit with the pipe 3 .

[0044] The bottom end of the displacement cross frame 9 is threadedly sleeved on the outer ring of the screw rod 30, the first rack 8 is meshed with the side end of the fifth gear 32 close to the workbench 38, the outer cover 18 is fixedly installed inside the support back frame 26, and the outer cover 18 is located above the winding wheel 20, the support back frame 26 is fixedly installed at the top rear end of the workbench 38, the end of the rubber roller 24 away from the first drive motor 25 is connected to the fourth gear 19, the second gear 16 is away from the side end center of the grinding wheel 14 and connected to the end opposite to the winding wheel 20, the tooth distribution angle of the first gear 15 is 270°, the fourth gear 19 is meshed with the third gear 17, and the fourth gear 19 is meshed with the third gear 17. A gear 15 is meshed with the second gear 16, the thickness of the first rack 8 and the second rack 33 are both at least 2 cm, the first rack 8 is meshed with the upper side end of the fifth gear 32, the second rack 33 is meshed with the lower front end of the fifth gear 32, the thickness of the fifth gear 32 is at least 5 cm, the front end of the second rack 33 is fixedly installed with a key, and the bottom rear end of the extended side frame 31 is provided with a slot, the top rear end of the workbench 38 is provided with a square hole, and a guide inclined plate is installed inside the square hole, the bottom end of the push plate 23 is fitted with the inner bottom end of the support back frame 26, and a rotating disk is rotatably installed on the opposite side end of the positioning push plate 37.

[0045] The working principle of Example 1 is as follows: when in use, first place the two pipes 3 on the workbench 38, then start the second drive motor 29 to drive the screw rod 30 to rotate, and thread the displacement cross frame 9 on the screw rod 30, so that when the screw rod 30 rotates, it can drive the displacement cross frame 9 to move toward one end close to the supporting back frame 26. At the same time, when the displacement cross frame 9 moves, it can drive the first rack 8 to pass through the fifth gear 32, thereby driving the fifth gear 32 to rotate. When the fifth gear 32 rotates, it can drive the second rack 33 to move toward one end close to the workbench 38, and the key at the front end of the second rack 33 slides in the slot at the rear end of the bottom of the extension side frame 31, so that the second rack 33 can be ensured to move in a straight line.

[0046] When the second rack 33 moves, it can drive the positioning base frame 34 and the alignment push plate 37 to move at the same time. When the alignment push plate 37 is moving, it can contact the end of the pipe 3, so that the two alignment push plates 37 can squeeze the pipe 3 to the top center of the workbench 38 until the two pipes 3 fit together to facilitate welding. Subsequently, if the displacement cross frame 9 needs to continue to move toward the rear end, it can drive the positioning base frame 34 to move continuously. The second spring 35 is installed between the positioning base frame 34 and the alignment push plate 37, so that when the first rack 8 drives the roller 6 to push the pipe 3 to contact the rubber roller 24, the second rack 33 can be continuously displaced.

[0047] When the pipe 3 is pushed to contact the rubber roller 24, the pipe 3 can also contact the grinding wheel 14. Subsequently, the welding device 2 can be started to weld the two pipes 3. At the same time, the first drive motor 25 can be started to drive the rubber roller 24 to rotate. The rubber roller 24 is fitted with the pipe 3, so that the pipe 3 can be driven to rotate. The pipe 3 is fitted with the rubber roller 24 and the roller 6 respectively, so that the rubber roller 24 can smoothly drive the pipe 3 to rotate, which is convenient for the welding device 2 to perform annular welding on the pipe 3. When the pipe 3 drives the weld to contact the grinding wheel 14, the rubber roller 24 rotates, which can drive the fourth gear 19 to rotate, and the fourth gear 19 can drive the third gear 17 to rotate, so that the third gear 17 can drive the grinding wheel 14 to rotate, so that the grinding wheel 14 can grind off the welding slag on the pipe 3.

[0048] The transmission ratio of the fourth gear 19 and the third gear 17 is 1:10, so that the grinding wheel 14 can be driven to rotate quickly, thereby improving the grinding efficiency of the grinding wheel 14. At the same time, the square hole at the rear end of the top of the workbench 38 is aligned with the front end of the grinding wheel 14, so that the welding slag can fall into the inside of the square hole, and a guide ramp is installed inside the square hole, so that the guide ramp can guide the welding slag to both sides to prevent the welding slag from directly contacting the screw rod 30. At the same time, when the third gear 17 rotates, it can also drive the first gear 15 to rotate, and when the first gear 15 rotates, it can drive the second gear 16 and the winding wheel 20 to rotate. When the winding wheel 20 rotates, the connecting rope 22 can be pulled to drive the push plate 23 to move toward the front end, and the bottom end of the push plate 23 is in contact with the inner bottom end of the support back frame 26, so that when the push plate 23 moves toward the front end, the welding slag accumulated at the inner bottom end of the support back frame 26 can be pushed toward the front end.

[0049] When the first gear 15 rotates 270°, the winding wheel 20 can be driven to pull the connecting rope 22 to drive the push plate 23 to move to the front end to the limit position, so that the welding slag at the bottom end of the inner side of the support frame 26 can fall into the square hole at the rear end of the top of the workbench 38. Subsequently, when the first gear 15 rotates 270°, the first gear 15 loses engagement with the second gear 16, and the elasticity of the first spring 28 drives the push plate 23 to quickly reset to the rear end, so that the push plate 23 can push the welding slag at the bottom end of the inner side of the support frame 26 again. When the push plate 23 is reset, the connecting rope 22 can be pulled to The winding wheel 20 rotates and resets to complete the work of quickly cleaning and diverting the welding slag. Subsequently, when the welding of the two pipes 3 is completed, the welding equipment 2 and the first drive motor 25 can be turned off, and then the second drive motor 29 can be started to drive the screw rod 30 to rotate in the opposite direction, thereby displacing the cross frame 9 to reset to the front end, so that the first rack 8 can pass through the fifth gear 32 again, thereby driving the second rack 33 to move to the end away from the workbench 38, and then the positioning push plate 37 can release the pipe 3, and the roller 6 can be out of contact with the pipe 3, so that the user can take out the welded pipe 3 to complete the work.

[0050] Example 2

[0051] On the basis of Example 1, Fig.10 As shown, the workbench 38 further includes a guide base frame 39 and a collecting cavity 40 . The guide base frame 39 is symmetrically fixedly mounted at the bottom rear end of the workbench 38 , and the collecting cavity 40 is slidably plugged into the guide base frame 39 .

[0052] When implementing this embodiment, the collecting chamber 40 is vertically aligned with the square hole inside the workbench 38, so that the collecting chamber 40 can receive the fallen welding slag, thereby avoiding the accumulation of welding slag at the welding site and facilitating the unified collection and treatment of the welding slag. Subsequently, the collecting chamber 40 can be pulled to the rear end so that the user can pour out the welding slag inside the collecting chamber 40. Subsequently, the collecting chamber 40 is placed on the inner bottom end of the guide base 39, and the collecting chamber 40 is pushed toward the inside of the workbench 38. By fitting the two ends of the collecting chamber 40 with the inner ends of the guide base 39, it is possible to ensure that the collecting chamber 40 moves in a straight line, which facilitates the collection chamber 40 to move in a straight line toward the inside of the workbench 38, thereby improving the docking accuracy between the collecting chamber 40 and the square hole, and completing the collection of welding slag.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
