Detailed Implementation
[0023] The technical solution of this utility model will be clearly and completely described below with reference to specific implementation schemes. However, those skilled in the art should understand that the implementation schemes described below are only for illustrating this utility model and should not be regarded as limiting the scope of this utility model. Based on the implementation schemes in this utility model, all other implementation schemes obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0024] This invention utilizes tungsten inert gas (TIG) welding to weld shock absorber housing components. TIG welding eliminates spatter and produces less smoke and dust. Compared to resistance welding, which generates sparks and electromagnetic interference during the welding process, TIG welding is more environmentally friendly and offers higher welding strength and stability.
[0025] In this invention, the electric arc heat is concentrated, allowing for precise control of welding heat input. The welding heat-affected zone is narrow, and no slag or spatter is produced during the welding process. The weld surface is relatively smooth, and there is no smoke or dust during the welding process. The molten pool is easy to control, resulting in high weld quality. Welding parameters can be precisely controlled, making it easy to achieve full automation of welding quality.
[0026] This invention reduces weld slag formation, improves weld strength and weld purity, and reduces electromagnetic interference and welding sparks. It also reduces the heat-affected zone and the degree of deformation of the welded parts. The system is equipped with an automatic feeding device, reducing labor costs.
[0027] like Figures 1-5 As shown, according to an embodiment of the present invention, a tungsten inert gas (TIG) welding system 100 for a shock absorber housing assembly 200 is provided. The shock absorber housing assembly 200 includes a tubular portion 201 and a square portion 202 to be welded to the tubular portion 201. The TIG welding system 100 includes a housing 10, a positioning mechanism 20, a feeding mechanism 30, and two TIG welding mechanisms 40.
[0028] The housing 10 includes a base 11, a frame 12, and a lift door 13 mounted on the frame 12.
[0029] The positioning mechanism 20 is mounted on the base 11. The positioning mechanism 20 is used to clamp the tubular part 201 and to make the end of the tubular part 201 to be welded face the inside of the frame 12.
[0030] The feeding mechanism 30 is used to clamp the square part 202 and move it to place it on the tubular part 201.
[0031] The tungsten inert gas (TIG) welding mechanism 40 is mounted on the base 11. The welding torch 46 on the TIG welding mechanism 40 can move to the tubular part 201 and the square part 202 to complete the welding.
[0032] It should be noted that the tungsten inert gas welding system 100 in this utility model is an automated device with a CNC panel and an intelligent control system.
[0033] In this utility model, the lifting door 13 needs to be lowered before welding. The lifting door 13 is used to separate the welding joint between the tubular part 201 and the square part 202, thus protecting the operator.
[0034] In some embodiments, the positioning mechanism 20 includes a connecting seat 21, a first abutting portion 22, a clamping portion 23, and a second abutting portion 24. The connecting seat 21 is disposed on the base 11. The first abutting portion 22 is disposed at one end of the connecting seat 21 and has a cylindrical member 221 abutting against the tubular portion 201, with at least a portion of the cylindrical member 221 located inside the tubular portion 201. The clamping portion 23 is disposed at the other end of the connecting seat 21 and clamps the tubular portion 201. The second abutting portion 24 is disposed at the other end of the connecting seat 21 and is located behind the clamping portion 23. The second abutting portion 24 has an abutting protrusion 241 abutting against the end face of the tubular portion 201.
[0035] It is understandable that a cylindrical member 221 is provided on the first contact portion 22, and at least a portion of the cylindrical member 221 is located inside the tubular portion 201, which helps to prevent the tubular portion 201 from rotating.
[0036] In some embodiments, there are three abutment protrusions 241, which are evenly distributed along the circumferential direction.
[0037] Understandably, setting three abutment protrusions 241 helps improve the positioning stability of the tubular part 201.
[0038] In some embodiments, the feeding mechanism 30 includes a first mounting bracket 31, a material frame 36, a first horizontal servo guide rail 32, a first connecting part 33, a first lifting assembly 34, and a robotic gripper 35. The first mounting bracket 31 is disposed on the base 11 and located behind the positioning mechanism 20. The first horizontal servo guide rail 32 is in the same direction as the positioning mechanism 20 and is disposed on the first mounting bracket 31. The first connecting part 33 is used to connect the first lifting assembly 34 and the first horizontal servo guide rail 32, and the first connecting part 33 drives the first lifting assembly 34 to move on the first horizontal servo guide rail 32. The robotic gripper 35 is disposed at the lower end of the first lifting assembly 34. The material frame 36 is disposed on the base 11 and located behind the positioning mechanism 20. The material frame 36 is used to hold the square part 202. The robotic gripper 35 is used to grip the square part 202 in the material frame 36 and move it to place it on the tubular part 201.
[0039] In some embodiments, the tungsten inert gas (TIG) welding mechanism 40 includes a second mounting bracket 41, a second horizontal servo rail 42, a second connecting portion 43, and a third horizontal servo rail 44. The second mounting bracket 41 is disposed on the base 11 and located on one side of the positioning mechanism 20. The second horizontal servo rail 42 is orthogonal to the positioning mechanism 20 and disposed on the second mounting bracket 41. The second connecting portion 43 is used to connect the third horizontal servo rail 44 and the second horizontal servo rail 42. The third horizontal servo rail 44 is in the same direction as the positioning mechanism 20. The second connecting portion 43 drives the third horizontal servo rail 44 to move on the second horizontal servo rail 42. The welding torch 46 is disposed on the third horizontal servo rail 44.
[0040] In some embodiments, the tungsten inert gas welding mechanism 40 further includes a fine-tuning mechanism 45, which includes a mounting base 451. The mounting base 451 is movably mounted on a third horizontal servo guide rail 44. A rotating column 452 is provided at the front end of the mounting base 451, and a welding torch 46 is mounted on the rotating column 452.
[0041] In some embodiments, the bottom of the rotating column 452 has a square base, and the top of the rotating column 452 has a clamping end.
[0042] Understandably, the square base at the bottom of the rotating column 452 helps to increase the force-bearing area and improve the stability of the fine-tuning mechanism 45.
[0043] In some embodiments, a scale is provided around the circumference of the square base.
[0044] Understandably, the design of the scale further improves the precision of fine-tuning.
