The synchronization component includes at least two through slots 47 running through the No. 2 three-jaw chuck 59. A plug rod 26 is provided through each of the through slots 47. One end of the plug rod 26 is inserted into the socket 46 opened on the No. 1 three-jaw chuck 25. A ball 38 is fixed to the other end of the plug rod 26. A baffle 37 is fixed on the plug rod 26. A No. 1 spring 36 is connected between the baffle 37 and the No. 2 three-jaw chuck 59. A guide ring 32 is fixedly mounted on one side of the bracket 31. The guide ring 32 is provided with a proximal end surface 33 and a distal end surface 35. The proximal end surface 33 and the distal end surface 35 are connected by two inclined surfaces 34. Each of the balls 38 is against the guide ring 32.

[0028] A welding gun 22 is mounted between the No. 1 three-jaw chuck 25 and the No. 2 three-jaw chuck 59. The welding gun 22 is positioned by a welding gun holder 50. The welding gun holder 50 can be used to adjust the position of the welding gun 22 to align with different welding points to accommodate engine oil pipe ends and engine oil pipes of different sizes. The welding gun holder 50 is mounted on a crossbar 15. The position of the welding gun holder 50 on the crossbar 15 can be manually adjusted. The crossbar 15 is fixedly mounted on a bracket 14, and the bracket 14 is fixed to the chassis 12.

[0029] The position of the distal end surface 35 corresponds to the position of the welding gun 22. When the No. 1 three-jaw chuck 25 drives the No. 2 three-jaw chuck 59 to rotate, each of the balls 38 moves along the guide ring 32. The balls 38 move outward along the inclined surface 34 until they abut against the distal end surface 35, which drives the insertion rod 26 at the welding gun 22 to move outward without blocking the operation of the welding gun 22.

[0030] Since the No. 1 three-jaw chuck 25 and the No. 2 three-jaw chuck 59 clamp and rotate together, there is no need to spot weld the engine oil pipe and the engine oil pipe end. They can be directly welded by the welding gun 22 during the rotation process, which can reduce the user's work and ensure the welding quality.

[0031] A pressure component 60 is also provided on the frame 11, and the pressure component 60 includes a slide groove 27 fixed to the frame 11, a slideway 28 is provided in the slide groove 27, a slider 57 is slidably installed in the slideway 28, and the slider 57 is fixed to the inner wall of one side of the slideway 28 by a No. 2 spring 29. A connecting rod 53 is fixed on the slider 57, a lever 52 is fixed on one side of the connecting rod 53, and a support plate 39 is fixed on the other side of the slider 57. An inserting plate 40 is slidably installed on the support plate 39, and a locking structure is provided between the support plate 39 and the inserting plate 40, and the locking structure includes a slot 55 provided on one side of the support plate 39, the inserting plate 40 is slidably provided in the slot 55, and limiting holes 43 are evenly provided on the support plate 39, and a matching hole 61 corresponding to one of the limiting holes 43 is provided on the inserting plate 40, which passes through The matching hole 61 is provided with a bolt 45 and one of the limiting holes 43. The bolt 45 is threadedly matched with a nut 44, and the support plate 39 and the plug plate 40 are locked by the bolt 45. Different limiting holes 43 are replaced to correspond to the matching holes 61, so as to adjust the length of the plug plate 40 extending out of the slot 55; a spring groove 56 is provided on one side of the plug plate 40, and a No. 3 spring 54 is fixed in the spring groove 56. A connecting piece 41 that is slidably connected to the spring groove 56 is fixed on one side of the No. 3 spring 54, and a shift lever 42 is fixed on the connecting piece 41. The shift lever 42 is used to resist the protruding part of the engine oil pipe, and the deformation of the No. 3 spring 54 provides a compressive force to the engine oil pipe and the engine oil pipe end, so that the engine oil pipe and the engine oil pipe end can be tightly fitted at the initial stage of welding to ensure the welding quality;

[0032] The second spring 29 is reset, driving the gear lever 42 to separate from the engine oil pipe. At this time, the partially welded engine oil pipe and the engine oil pipe end continue to move and be welded, and the connecting piece 41 and the gear lever 42 are reset.

[0033] It should be noted that the No. 1 three-jaw chuck 25 and the No. 2 three-jaw chuck 59 are both conventional three-jaw chuck structures. By adjusting the upper jaws, they can adapt to engine oil pipes and engine oil pipe ends of different diameters. The adjustment method is generally manual.

[0034] It should be noted that a control terminal is integrated in the chassis 12 to control the operation of the motor 13 .

[0035] Directions:

[0036] When in use, manually place the end of the engine oil pipe into the No. 1 three-jaw chuck 25 for adjustment and clamping, insert the engine oil pipe into the No. 2 three-jaw chuck 59 and align it with the end of the engine oil pipe, manually pull out the shift lever 42 to press against the protruding part of the engine oil pipe, and provide the engine oil pipe and the end of the engine oil pipe with a compressive force through the deformation of the No. 3 spring 54. After completion, adjust the No. 2 three-jaw chuck 59 to clamp the engine oil pipe as well;

[0037] The welding gun holder 50 is manually adjusted so that the welding gun 22 is aligned with the welding position, and the motor 13 is started. The motor 13 drives the turntable 24 to rotate, and the No. 1 three-jaw chuck 25 rotates along with the turntable 24. When the No. 1 three-jaw chuck 25 drives the No. 2 three-jaw chuck 59 to rotate, each of the spheres 38 moves along the guide ring 32. The spheres 38 move outward along the inclined surface 34 until they abut against the distal end surface 35, which drives the insertion rod 26 at the welding gun 22 to move outward so as not to block the operation of the welding gun 22.

[0038] After the No. 1 three-jaw chuck 25 rotates, it drives the push rod 51 to rotate. The push rod 51 pushes the shift rod 52, causing the slider 57 to move and the No. 2 spring 29 to be compressed. At this time, the welding gun 22 performs preliminary welding on the engine oil pipe and the end of the engine oil pipe. After welding a part, the slider 57 cannot move, the push rod 51 twists and separates from the shift rod 52, and the No. 2 spring 29 resets, driving the shift rod 42 to separate from the engine oil pipe. At this time, the partially welded engine oil pipe and the end of the engine oil pipe continue to move and be welded, and the connecting piece 41 and the shift rod 42 reset;

[0039] The turntable 24 stops after rotating one circle, completing the welding operation, and the welded product is manually removed.

[0040] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those skilled in the art to understand and implement the present invention. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications made in accordance with the spirit of the present invention are intended to be covered by the scope of protection of the present invention.
