Description

Technical Field

[0001] The invention belongs to the technical field of electric welding machine supporting devices, and in particular relates to a portable overlapping structure of a secondary bottom line of an electric welding machine. Background Art

[0002] At present, as a traditional basic industry, the steel industry is limited by its own characteristics and it is difficult to manage the site according to the 6S standard. However, with the needs of industrial development in recent years, high-quality development requires the entire industry to upgrade. What cannot be ignored is that the steel industry must quickly get rid of the old appearance of "dirty, messy and poor", and gradually promote clean production and standardized operations. The current steel industry generally has habits such as non-standard welding operations, habitual or unconscious violations of regulations.

[0003] After searching, Chinese patent CN212257739U proposes a simple electric welding machine secondary wire and weldment overlap device, including a bakelite board, one end of the bakelite board is fixedly connected to a strong magnet through a first screw, and the other end of the bakelite board is provided with a second screw with a copper head, and the copper head and the strong magnet are located on the same side of the bakelite board, which can improve on-site welding efficiency, promote production, ensure safe production, and reduce corresponding production costs.

[0004] However, in actual use of the above-mentioned prior art, it is found that the magnetic block will inevitably be affected and generate heat during welding. When the temperature of the magnetic block increases, the magnetism will gradually decay, and the fixing effect will also be weakened accordingly. At this time, if the connecting line is accidentally touched, the magnetic block will fall off from the welded part. At this time, it is difficult for the operator to find it, and the detached secondary line and the welded object cannot be connected in time, which is very likely to cause accidents.

[0011] In the above technical solution, further, a plurality of second plug rods are inserted and slidably connected to the top of the mounting block, a same pressing handle is fixedly connected to the tops of the plurality of second plug rods, and a second spring is sleeved on the outside of the second plug rods.

[0012] In the above technical solution, further, the bottom of the pressing handle is fixedly connected with a plurality of spring pieces distributed in a circular array, and the spring pieces are made of metal material, and the bottoms of the plurality of spring pieces distributed in a circular array are commonly fixedly connected with a contact block, and an impact groove is provided at the bottom of the contact block.

[0013] In the above technical solution, further, a temperature insulation ring is sleeved on the outer wall of the mounting block.

[0014] In the above technical solution, further, the connecting assembly includes a fixed cylinder fixedly connected between the two connecting frames, a hollow cylinder is arranged inside the fixed cylinder, a first connecting rod is slidably connected and inserted through the inside of the hollow cylinder, and the first connecting rod is fixedly connected to the bottom of the outer wall of the wiring rod, a movable block slidably connected to the inside of the hollow cylinder is fixedly connected to the bottom of the first connecting rod, a fourth spring is fixedly installed between the movable block and the top of the inner wall of the hollow cylinder, a second connecting rod is inserted and slidably connected to the bottom of the movable block, and the second connecting rod is fixedly connected and inserted through the bottom of the outer wall of the hollow cylinder, a movable ball is fixedly connected to the bottom of the second connecting rod, a support plate is fixedly connected to the bottom of the fixed cylinder, a movable ball sleeve is fixedly connected to the top of the support plate, and the movable ball is rotatably installed inside the movable ball sleeve, a first baffle is fixedly connected to the bottom of the support plate, third plug rods are inserted and slidably connected to both sides of the outer wall of the first baffle, the bottoms of the two third plug rods are fixedly connected to the same second baffle, a third spring is sleeved on the outside of the third plug rod, and a copper contact head is fixedly connected to the bottom of the second baffle.

[0015] In the above technical solution, further, a tensioning belt is fixedly connected between the fixed cylinder and the hollow cylinder.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] By providing two first magnetic blocks, the two first magnetic blocks are respectively placed on both sides of the connection component and are far away from each other. During welding, it is only necessary to fix them to one side edge of the welded object, so that one of the first magnetic blocks is far away from the welding area. Then, even if the magnetism of the first magnetic block close to the welding area begins to decay due to the high temperature, the other first magnetic block can still maintain a strong magnetism to firmly fix the connection component on the welded object, thereby solving the problem that the magnetic block is easily separated from the welded object in the prior art.

[0018] By setting a number of small second magnetic blocks, compared with setting a whole block, on the one hand, the size of the first magnetic block is reduced, and it will be more difficult for it to contact the temperature from the welding area. On the other hand, the second magnetic block far away from the welding area is blocked by other second magnetic blocks together with the first magnetic block, and the environment in which it is located has sufficient temperature isolation blocking conditions, so that sufficient magnetism can be maintained so that the corresponding fixed component can still maintain the fixing effect. This design enables the fixed component to still maintain the magnetism of at least one second magnetic block during long-term welding work, and then form symmetry with another fixed component to make the contact between the connection component and the welded object more stable. By setting the impact ball, the second magnetic block is stored in the movable groove by the pulling force of the first spring when not in use, avoiding it from being exposed to the outside and attracting a large amount of metal debris;

[0019] After the second magnetic block loses its magnetism, it will be pulled by the first spring, and in the process, the impact ball will be driven to hit the contact block, thereby generating a sound to remind the operator that one of the second magnetic blocks has lost its magnetism, and the fixing effect of other second magnetic blocks should be checked. When multiple second magnetic blocks lose their magnetism at the same time, they will be pulled by the first spring together, so that multiple impact balls will hit the contact block in succession at the same time, and the tone will be significantly increased, which has a functional increase in reminder. At the same time, the metal shrapnel will not only buffer the impact of the impact after being hit, but also generate sound itself to enhance the reminder effect;

[0020] By providing a hollow cylinder and a movable ball, the copper contact head, the fixed cylinder and the fixed component are connected as a whole and are not affected by the connecting wire. Compared with the prior art, it is less likely to loosen and has a more stable contact with the welded object. When the connecting wire is contacted and pulls the first connecting rod, the movable block moves inside the hollow cylinder to offset the backward pulling force to a certain extent, and the movable ball rotates inside the movable ball sleeve to offset the force of the connecting wire flipping in other directions to a certain extent. Even if the connecting wire is accidentally touched during welding, such as tripping or pushing, it will not affect the fixing effect of the fixing component under a certain force, thereby greatly improving its overall stability and preventing it from falling during use.

DETAILED DESCRIPTION

[0028] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 1-Figure 6The portable overlapping structure of the secondary bottom line of an electric welding machine shown in the figure comprises a connecting rod 1, a fixing member 2 is arranged on the outer wall of the connecting rod 1, a connecting assembly 3 is arranged at the bottom of the connecting rod 1, both sides of the connecting assembly 3 are fixedly connected with a connecting frame 4, one end of the connecting frame 4 is provided with a fixing assembly 5, the fixing assembly 5 is used to fix the connecting assembly 3 on the surface of the welding object, the fixing assembly 5 comprises a mounting block 6 fixedly connected to one end of the outer wall of the connecting frame 4, the bottom of the mounting block 6 is fixedly connected with a first magnetic block 7, by arranging two first magnetic blocks 7, the two first magnetic blocks 7 are respectively placed on both sides of the connecting assembly 3 and are far away from each other, in the welding work, it only needs to be fixed to one side edge of the welding object, so that one of the first magnetic blocks 7 is away from the welding area, and then even if the first magnetic block 7 close to the welding area begins to decay due to the magnetism contained in the high temperature, the other first magnetic block 7 can still maintain a strong magnetism to firmly fix the connecting assembly 3 on the welding object, thereby solving the problem that the magnetic block is easily detached from the welding object in the prior art.

[0030] The bottom of the mounting block 6 is provided with evenly distributed movable grooves 10, and the second magnetic block 8 is slidably installed inside the movable groove 10. The top of the second magnetic block 8 is fixedly connected with a first plug rod 11, and the first plug rod 11 is slidably connected and inserted through the top of the mounting block 6. The outside of the first plug rod 11 is sleeved with a first spring 12, and the end of the first plug rod 11 is fixedly connected with an impact ball 13. By setting a plurality of small second magnetic blocks 8, compared with the whole block setting, on the one hand, the size of the first magnetic block 7 is reduced, and it will be more difficult for it to contact the temperature from the welding area, and on the other hand, the second magnetic block 8 away from the welding area The other second magnetic blocks 8 together with the first magnetic block 7 are blocked, and the environment in which they are located has sufficient insulation temperature blocking conditions, so that sufficient magnetism can be maintained so that the corresponding fixing component 5 can still maintain the fixing effect. This design enables the fixing component 5 to still maintain the magnetism of at least one second magnetic block 8 during long-term welding work, and then form symmetry with another fixing component 5 to make the contact between the connecting component 3 and the welded object more stable. By setting the impact ball 13, the second magnetic block 8 is stored in the movable groove 10 by the pulling force of the first spring 12 when not in use, avoiding it from being exposed to the outside and attracting a large amount of metal debris.

[0031] A plurality of second plug rods 15 are inserted and slidably connected to the top of the mounting block 6, and a same pressing handle 33 is fixedly connected to the top of the plurality of second plug rods 15. A second spring 14 is sleeved on the outside of the second plug rods 15. Pressing the pressing handle 33 can contact all the impact balls 13 and drive them to descend synchronously, thereby exposing the second magnetic block 8 originally housed in the movable groove 10 to the outside. This design significantly simplifies the operation process of driving out the second magnetic block 8.

[0032] The bottom of the pressing handle 33 is fixedly connected with a plurality of spring pieces 16 distributed in a plurality of circular arrays, and the spring pieces 16 are set to a metal material. The bottom of the plurality of spring pieces 16 distributed in a circular array is commonly fixedly connected with a contact block 17, and a collision groove 18 is provided at the bottom of the contact block 17. After the second magnetic block 8 loses its magnetism, it will be pulled by the first spring 12, and in the process, the collision ball 13 will be driven to hit the contact block 17, thereby generating a sound to remind the operator that one of the second magnetic blocks 8 has lost its magnetism and the fixing effect of other second magnetic blocks 8 should be checked. When multiple second magnetic blocks 8 lose their magnetism at the same time, they will be pulled by the first spring 12 together, so that multiple collision balls 13 will hit the contact block 17 in succession at the same time, and the tone will be significantly increased, which has an increase in the reminder function. At the same time, the metal spring piece 16 will not only buffer the impact of the impact after being hit, but also produce a sound to enhance the reminder effect.

[0033] A thermal insulation ring 9 is sleeved on the outer wall of the mounting block 6 . This design can reduce excessive heat absorption by the first magnetic block 7 and the second magnetic block 8 .

[0034] The connecting assembly 3 is used to connect the welding object and the wiring rod 1. The connecting assembly 3 includes a fixed cylinder 19 fixedly connected between two connecting frames 4. A hollow cylinder 21 is arranged inside the fixed cylinder 19. A first connecting rod 20 is slidably connected and inserted inside the hollow cylinder 21, and the first connecting rod 20 is fixedly connected to the bottom of the outer wall of the wiring rod 1. The bottom of the first connecting rod 20 is fixedly connected to a movable block 27 slidably connected to the inside of the hollow cylinder 21. A fourth spring 34 is fixedly installed between the movable block 27 and the top of the inner wall of the hollow cylinder 21. A second connecting rod 29 is inserted and slidably connected at the bottom of the movable block 27, and the second connecting rod 29 is fixedly connected and inserted through the bottom of the outer wall of the hollow cylinder 21. A movable ball 30 is fixedly connected to the bottom of the second connecting rod 29. A support plate 32 is fixedly connected to the bottom of the fixed cylinder 19. A movable ball sleeve 31 is fixedly connected to the top of the support plate 32. The movable ball 30 is rotatably installed inside the movable ball sleeve 31. The bottom of the support plate 32 is fixedly connected to the first baffle plate 22. A third plug rod 23 is inserted through and slidably connected on both sides of the outer wall. The bottom of the two third plug rods 23 is fixedly connected to the same second baffle 25. The third plug rod 23 is sleeved with a third spring 24 on the outside. The bottom of the second baffle 25 is fixedly connected to a copper contact head 26. During use, by arranging the hollow cylinder 21 and the movable ball 30, the copper contact head 26 and the fixed cylinder 19 are connected as a whole with the fixed component 5, and are not affected by the connecting line. Compared with the prior art, it is less likely to loosen and the contact with the welded object is more stable. When the connecting line is contacted and the first connecting rod 20 is pulled, the movable block 27 moves inside the hollow cylinder 21 to offset the backward pulling force to a certain extent, and the movable ball 30 rotates inside the movable ball sleeve 31 to offset the force of the connecting line flipping in other directions to a certain extent, so that even if the connecting line is accidentally touched during welding, such as tripping or pushing, it will not affect the fixing effect of the fixing component 5 under a certain force, thereby greatly improving its overall stability and not easy to fall during use.

[0035] A tension belt 28 is fixedly connected between the fixed cylinder 19 and the hollow cylinder 21. During the rotation of the movable ball 30 inside the movable ball sleeve 31, the tension belt 28 can provide elastic resistance to buffer its turning force on the one hand, and on the other hand, after the second connecting rod 29 loses its force, it can use its own elasticity to quickly center the hollow cylinder 21.

[0036] Working principle:

[0037] By providing two first magnetic blocks 7, the two first magnetic blocks 7 are respectively placed on both sides of the connecting component 3 and are far away from each other. During welding, it is only necessary to fix them to one side edge of the welded object, so that one of the first magnetic blocks 7 is far away from the welding area. Then, even if the magnetism of the first magnetic block 7 close to the welding area begins to decay due to the high temperature, the other first magnetic block 7 can still maintain a strong magnetism to firmly fix the connecting component 3 on the welded object, thereby solving the problem that the magnetic block is easily separated from the welded object in the prior art.

[0038] By setting a number of small second magnetic blocks 8, compared with the whole block setting, on the one hand, the size of the first magnetic block 7 is reduced, and it will be more difficult for it to contact the temperature from the welding area. On the other hand, the second magnetic block 8 far away from the welding area is blocked by other second magnetic blocks 8 together with the first magnetic block 7, and the environment in which it is located has sufficient insulation temperature blocking conditions, so that sufficient magnetism can be maintained so that the corresponding fixing component 5 can still maintain the fixing effect. This design enables the fixing component 5 to still maintain the magnetism of at least one second magnetic block 8 during long-term welding work, and then it can form symmetry with another fixing component 5 to make the contact between the connecting component 3 and the welded object more stable. By setting the impact ball 13, the second magnetic block 8 is stored in the movable groove 10 by the pulling force of the first spring 12 when not in use, avoiding it from being exposed to the outside and attracting a large amount of metal debris;

[0039] After the second magnetic block 8 loses its magnetism, it will be pulled by the first spring 12, and in the process, the impact ball 13 will be driven to hit the contact block 17, thereby generating a sound to remind the operator that one of the second magnetic blocks 8 has lost its magnetism, and the fixing effect of other second magnetic blocks 8 should be checked. When multiple second magnetic blocks 8 lose their magnetism at the same time, they will be pulled by the first spring 12 together, so that multiple impact balls 13 will hit the contact block 17 in succession at the same time, and the tone will be significantly increased, which has a functional increase in reminder. At the same time, the metal spring piece 16 will not only buffer the impact of the impact after being hit, but also generate sound to enhance the reminder effect.

[0040] By providing the hollow cylinder 21 and the movable ball 30, the copper contact head 26 and the fixed cylinder 19 are connected as a whole with the fixed component 5, and are not affected by the connecting wire. Compared with the prior art, they are less likely to loosen and have more stable contact with the welded object. When the connecting wire is contacted and pulls the first connecting rod 20, the movable block 27 moves inside the hollow cylinder 21 to offset the backward pulling force to a certain extent, and the movable ball 30 rotates inside the movable ball sleeve 31 to offset the force of the connecting wire flipping in other directions to a certain extent, so that even if the connecting wire is accidentally touched during welding, such as tripping or pushing, it will not affect the fixing effect of the fixed component 5 under a certain force, thereby greatly improving its overall stability and preventing it from falling during use.
