Description

Technical Field

[0001] This utility model relates to the field of welding machine transfer technology, specifically to a portable traction component for a gas shielded welding machine used for steel component processing. Background Technology

[0002] Gas shielded welding machines, also known as gas-shielded welding machines, are arc welding machines that use gas as a medium to simultaneously protect the electric arc and the welding area. During the welding process, the gas shielded welding machine continuously delivers gas through a nozzle, forming a localized gas protective layer around the arc. This keeps the electrode tip, molten droplets, and molten pool metal within the protective gas shield, thus isolating them from air, ensuring the stability of the welding process, and obtaining high-quality welds. Portable traction components allow for easier movement and transfer of the gas shielded welding machine between different work sites, improving its portability and flexibility. This is particularly important for the steel component processing industry, which requires welding operations at multiple construction sites or in different locations.

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1

[0027] like Figures 1-4 As shown, this embodiment proposes a portable traction assembly for a gas shielded welding machine for steel component processing, including a frame 1, a support plate 2 fixedly connected to the top left side of the frame 1, a platform 3 provided on the top of the frame 1, an adjustment mechanism 4 provided between the support plate 2 and the platform 3, a connecting rod 5 fixedly connected to the top of the frame 1 and located between the support plate 2 and the platform 3, an oiling mechanism 6 provided on the top of the support plate 2, and multiple sets of limiting mechanisms 7 provided inside the platform 3;

[0028] The adjustment mechanism 4 includes a motor 41 and two L-shaped plates 43. The bottom of the motor 41 is fixedly connected to the top of the frame 1, and the bottom of the L-shaped plates 43 is fixedly connected to the top of the support plate 2. A lead screw 44 is fixedly connected to the output end of the motor 41, and a threaded sleeve 45 is threadedly connected to the outer circumference of the lead screw 44. A guide rod 42 is fixedly connected to the bottom of one of the L-shaped plates 43. The bottom of the guide rod 42 is fixedly connected to the top of the frame 1, and a slider 46 is slidably connected to the outer side of the guide rod 42. A connecting frame 47 is fixedly connected between the threaded sleeve 45 and the slider 46. The right side of the connecting frame 47 is fixedly connected to the left side of the storage platform 3.

[0029] The oiling mechanism 6 includes a sleeve 61, an oil storage tank 62, and an extrusion block 63. The outer side of the sleeve 61 is fixedly connected to the front side of the front L-shaped plate 43, and the right side of the sleeve 61 is fixedly connected to the left side of the front L-shaped plate 43. The rear side of the extrusion block 63 is fixedly connected to the front side of the threaded sleeve 45. A push rod 64 is slidably connected inside the sleeve 61. A piston 65 is fixedly connected to the left side of the push rod 64, and a roller 66 is installed on the right side of the push rod 64. Two springs 67 are installed inside the sleeve 61. An oil extraction pipe 68 is fixedly connected to the left side of the sleeve 61. The end of the oil extraction pipe 68 away from the sleeve 61 is fixedly connected to the outside of the oil storage tank 62. A delivery pipe 69 is fixedly connected to the top of the sleeve 61. The end of the delivery pipe 69 away from the sleeve 61 is fixedly connected to the right side of the front L-shaped plate 43.

[0030] The purpose of this setup is to provide a starting motor 41 to drive the lead screw 44 to rotate when height adjustment is required. The rotation of the lead screw 44 drives the threaded sleeve 45 to move, which, in conjunction with the slider 46, drives the connecting frame 47 to move synchronously, thereby moving the platform 3. Once the desired position is reached, the motor 41 can be turned off. To prevent the lead screw 44 from jamming during long-term use, the starting motor 41 drives the lead screw 44 to rotate, which in turn drives the threaded sleeve 45 to move. The movement of the threaded sleeve 45 drives the abutment block to move upward synchronously. When the pressing block 63 and the roller 66 abut, the abutment block drives the push rod 64, which pushes the piston 65. The piston 65 pulls the spring 67, causing the spring 67 to generate elastic force. When pushed, the lubricating oil inside the sleeve 61 is squeezed. At this time, the one-way valve 610 on the delivery pipe 69 automatically opens, allowing the lubricating oil to be sprayed from the delivery pipe 69 to the outer periphery of the lead screw 44. As the lead screw 44 rotates and under the action of gravity, the lubricating oil will fall and wet the entire lead screw 44. Then, the inner side of the threaded sleeve 45 will contact the outer side of the lead screw 44, thereby wetting the inner side of the threaded sleeve 45. When the squeezing block 63 does not abut against the roller 66, the one-way valve 610 on the oil extraction pipe 68 automatically opens, and the spring 67 pulls the piston 65 to reset. At the same time, the piston 65 draws out the lubricating oil inside the oil storage tank 62 through the oil extraction pipe 68 and delivers it to the inside of the sleeve 61. After adding an appropriate amount of lubricating oil, the motor 41 can be turned off, and the oiling mechanism 6 stops running.

[0031] Preferably, the top of the lead screw 44 is rotatably connected to the bottom of the L-shaped plate 43, and the inner side of the connecting frame 47 is slidably connected to the outer side of the connecting rod 5. The purpose of this arrangement is that the rotatable connection between the lead screw 44 and the L-shaped plate 43 allows the lead screw 44 to rotate stably, while also limiting the threaded sleeve 45. The slidable connection between the connecting frame 47 and the connecting rod 5 allows the connecting frame to drive the platform 3 to slide more stably.

[0032] Preferably, one end of spring 67 is fixedly connected to the inner wall of sleeve 61, and the other end of spring 67 is fixedly connected to the outside of piston 65. The purpose of this arrangement is that spring 67 provides elastic force for piston reset.

[0033] Preferably, the piston 65 is slidably connected to the inner side of the sleeve 61, and the roller 66 abuts against the extrusion block 63. The purpose of this arrangement is that the piston 65 and the sleeve 61 are slidably connected so that the piston 61 can slide more stably. When the inclined surface of the extrusion block 63 abuts against the roller 66, the lubricating oil can be intermittently squeezed into the delivery pipe 69.

[0034] Preferably, a one-way valve 610 is provided on the outside of both the delivery pipe 69 and the oil extraction pipe 68. The purpose of this arrangement is that the one-way valve 610 on the delivery pipe 69 allows lubricating oil to flow out but not in, and the one-way valve 610 on the oil extraction pipe 68 allows lubricating oil to flow into but not out of the oil extraction pipe 68.

[0035] Example 2

[0036] like Figure 3 and Figure 5 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes a limiting mechanism 7 including a mounting frame 71. The outer side of the mounting frame 71 is fixedly connected to the inner side of the shelf 3. A moving rod 72 is slidably connected inside the mounting frame 71. A baffle 73 is fixedly connected to the left side of the moving rod 72. A limiting plate 74 is fixedly connected to the right side of the baffle 73. A spring 75 is provided inside the mounting frame 71.

[0037] The purpose of this design is that, during use, the welding machine is placed between the four limiting plates 74. Under the action of the second spring 7575, the baffle 73 is pushed outward, and then the moving rod 72 drives the limiting plates 74 to limit the welding machine. At the same time, it provides a buffer function for the welding machine during transportation, so as to avoid the welding machine shaking during transportation, which could cause collisions or friction between parts and thus damage the welding machine.

[0038] Preferably, one end of the second spring 75 is fixedly connected to the inner wall of the mounting frame 71, and the other end of the second spring 75 is fixedly connected to the outer side of the baffle 73. The outer side of the baffle 73 is slidably connected to the inside of the mounting frame 71. The purpose of this arrangement is that the second spring 75 provides elastic force for the baffle 73 to reset, and at the same time provides buffering for the welding machine during transportation. The slidable connection between the baffle 73 and the mounting frame 71 allows the baffle 73 to slide stably.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
