Background Art

Auxiliary welding devices for new energy vehicle chassis accessories generally refer to auxiliary equipment or devices used in the welding process of new energy vehicle chassis parts. These devices are generally designed to improve welding quality, efficiency and the safety of the working environment.

After searching, a Chinese patent with announcement number CN206632576U discloses a chassis welding auxiliary device, which includes a supporting device, a fixing device and a lifting device. The supporting device includes a supporting frame and a fixing frame, and the supporting frame is fixedly connected through the fixing frame. The fixing device includes a rotating shaft and a fixed disk, and the fixed disk is fixedly connected to the rotating shaft. The lifting device includes a motor, a lifting frame and a pulley block, and the pulley block is connected by a belt, and the pulley block is fixedly connected to the lifting frame, and the motor is connected to the lifting frame through a driving wheel. The above scheme can weld chassis of different heights, can adjust the position of the chassis to be welded, which is convenient for the staff to weld, and can rotate the chassis to facilitate the welding of different components. However, the above scheme still has the following shortcomings when it is actually used:

The automotive parts welding auxiliary device proposed in the above scheme cannot stably clamp special-shaped automotive parts, which causes the parts to shake easily due to unstable clamping during welding. If the parts shake during welding, the welding point will be unstable or the weld quality will be uneven, which may affect the welding strength and connection quality, and may even cause welding defects such as incomplete fusion or porosity, thereby affecting the service life and safety of the parts. In addition, shaking parts will not only affect the welding quality, but also increase the risk of injury to the operator. Unstable parts may cause unexpected sparks or poor contact of the welding tools, causing personal injury. Secondly, because shaking parts require additional adjustments and repeated operations, this will increase the welding cycle time and production costs. The inability to stably clamp the parts may also increase the downtime of the production line, further reducing production efficiency.

The present invention has the following beneficial effects:

1. By setting up the placement structure, the slide bar of the device has telescopic characteristics and can adapt to automobile chassis accessories of different shapes and sizes. This flexibility allows the device to be widely used in different welding tasks. Regardless of the shape of the chassis accessories, it can provide stable support and positioning. The staff only needs to place the chassis accessories on the slide bar, and the device can automatically adjust and fix the position, which simplifies the operation process, reduces the workload of operators, and improves work efficiency. Since the chassis accessories remain stable during welding and will not shake or move, the precise alignment of the welding joint and the quality of the weld can be ensured, which is especially important for parts such as automobile chassis that require high welding accuracy;

2. By setting the wire and the electrorheological fluid, the electrorheological fluid in the sealing tube is solidified by energizing the wire, thereby increasing the stability of the slide seat and the slide rod. In this way, during the welding process, the device can effectively fix the position of the slide rod, ensuring the accurate positioning and stability of the chassis accessories. Since the slide rod and the slide seat are fixed under the action of the electrorheological fluid, the chassis accessories will not cause the displacement or inaccuracy of the welding joint due to movement or shaking during the welding process, which further ensures the consistency and high level of welding quality;

3. Through the design of the suction piece and the exhaust hood, the device can effectively extract the fume generated during the welding process, including welding fumes and gas emissions, thereby preventing these harmful substances from spreading into the working environment and protecting the health of the workers. In addition, the fume absorption structure introduces the extracted fume into the water tank, and through the action of water, effectively captures and precipitates smoke and solid particles. The large surface area and chemical properties of water enable it to effectively dissolve and absorb gaseous pollutants and volatile organic compounds, such as carbon monoxide. The box design that integrates the fume absorption and purification functions not only makes the welding process cleaner and safer, but also improves the work efficiency and comfort of the workers, and reduces the operation interference and suspension time caused by fume and welding slag;

4. The mobile frame is pulled by the traction line to enable the slag cleaning seat to move along the top surface of the lifting plate. During the movement, the slag cleaning seat fits the top surface of the lifting plate, pushes the welding slag on the top surface toward one end of the lifting plate, and makes the welding slag fall from one end of the lifting plate onto the welding table. In this way, the welding slag generated during the welding process can be cleaned in time. The automatic welding slag cleaning mechanism reduces the need for manual intervention, making the welding operation more continuous and efficient. Compared with manual welding slag cleaning, this automated slag cleaning device reduces the dependence on staff, thereby improving overall work efficiency and safety;

5. The slag cleaning seat can generate vibrations by driving the coordinated movement of the trigger assembly and the actuator assembly through the rotation of the eccentric wheel. This vibration helps to effectively push away the welding slag adhering to the top surface of the lifting plate, ensuring that the welding slag can be completely detached from the lifting plate, ensuring the cleaning effect of the welding slag. By regularly and thoroughly cleaning the welding slag, the lifting plate and welding equipment can be effectively protected from wear and damage caused by the accumulation of welding slag, thus extending the service life of the equipment.

6. The flue gas absorption structure and the traction structure are driven by the same motor. The power distribution of the motor is controlled by the control structure. There is no need to set up multiple power sources. The integrated drive system makes the equipment design more concise. No additional power source or complex mechanical structure is required. The same motor is used to drive two different functional modules. The working process can be adjusted and managed through a unified control structure, which simplifies the operation process, reduces the learning cost of operators, and improves the overall operation efficiency and accuracy of the equipment.

7. The welding slag generated during the welding process is pushed by the slag cleaning seat and falls from the top of the lifting plate into the welding slag collection space on the welding table. This process utilizes the grid plate on the top of the welding table. The welding slag can fall into the collection space through the gap on the grid plate and then slide into the detachable collection drawer. This design effectively collects and stores the welding slag generated during the welding process. The collection drawer design makes the cleaning operation of the welding slag very convenient. The staff can easily take out the collection drawer regularly to remove the accumulated welding slag, which is convenient to operate.

In this case, the top ends of the plurality of slide bars 53 in contact with the automobile chassis accessory can jointly form a placement area adapted to the shape of the automobile chassis accessory, which enables the position of the automobile chassis accessory to be fixed. When the staff welds the automobile chassis accessory, the automobile chassis accessory will not shake, thereby ensuring the welding effect. The retractable characteristics of the plurality of retractable parts enable the placement structure to position automobile chassis accessories of different shapes, and has strong adaptability.

Furthermore, each sealing cylinder 51 is filled with electrorheological fluid, and each sealing cylinder 51 is provided with a wire 56, and a plurality of wires 56 form a series connection circuit. When the automobile chassis parts are placed on the placement structure, after the automobile chassis parts reach a stable state, the staff energizes the plurality of wires 56 at the same time. When the plurality of wires 56 are energized, the electrorheological fluid in the plurality of sealing cylinders 51 can be "cured", that is, the viscosity of the electrorheological fluid in the plurality of sealing cylinders 51 can be greatly increased, thereby fixing the positions of the plurality of slide seats 52, and the positions of the plurality of slide bars 53 can also be fixed. This design can ensure the position stability of the plurality of slide bars 53, thereby ensuring To prove the positioning effect of the plurality of slide bars 53 on the chassis accessories of the automobile, it should be noted that the specific principle of the electrorheological fluid is a prior art, which will not be described in detail here. In addition, a power supply for supplying power to the plurality of wires 56 is provided on the welding table 1, and a control switch is also installed on the power supply to facilitate the staff to control the on and off of the current in the plurality of wires 56. This part is also a prior art and is not an innovative part of the technical solution, which will not be described in detail here. In addition, a plurality of through holes 55 are provided on each slide seat 52. During the movement of the slide seat 52, the electrorheological fluid can flow through the plurality of through holes 55. The design of the through holes 55 is conducive to the movement of the slide seat 52 in the sealing cylinder 51.

In addition, the box body 2 is also provided with a fume absorption structure and a slag cleaning structure. The fume absorption structure is used to absorb the fume generated during welding, and the slag cleaning structure is used to clean the welding slag generated during welding. For the fume absorption structure, when welding, the staff starts the motor 83. When the motor 83 is running, it can drive the driving rod 84 to rotate, so that the driving rod 84 drives the suction member 85 to rotate. The suction member 85 is composed of a plurality of axial flow blades. When the suction member 85 rotates, it can perform a suction action, and extract air through the suction pipe 86, the metal bellows 81 and the suction hood 87. Therefore, the staff can align the suction hood 87 with the welding position of the automobile chassis accessories, and use the fume absorption structure to extract the fume generated during welding. The setting of the metal bellows 81 facilitates the staff to flexibly adjust the position of the suction hood 87. Furthermore, the interior of the box body 2 is also provided with a fume purification structure. The fume extracted by the fume absorption structure The smoke is discharged through the air inlet pipe 92, and water flow is accumulated in the water tank 91. The end of the air inlet pipe 92 away from the air pump 82 is immersed in the water. Therefore, the smoke discharged through the air inlet pipe 92 can enter the water and then escape from the water in the form of bubbles. In this process, the water flow can effectively capture and precipitate most of the smoke and solid particles. This is because the water flow can provide a large surface area, so that the solid particles suspended in the smoke settle when they come into contact with the water, thereby significantly reducing the particle concentration in the smoke. In addition, water can absorb gaseous pollutants and some volatile organic compounds in the smoke. In water, these compounds may dissolve or be surrounded and removed by water molecules through physical adsorption. In particular, for some gaseous pollutants that are easily soluble in water, such as carbon monoxide, water can effectively absorb them. Therefore, the smoke passing through the water flow can be purified and then discharged from the box body 2 through the exhaust pipe 93;

As for the slag cleaning structure, when welding the automobile chassis accessories, the plurality of slide bars 53 respectively pass through the plurality of through holes on the lifting plate 3. At this time, the lifting plate 3 is set on the top of the plurality of sealing cylinders 51. The welding slag generated during the welding process will fall on the surface of the lifting plate 3. After the welding work is completed, the staff removes the automobile chassis accessories from the placement structure, and then pulls up the lifting plate 3 until the lifting plate 3 moves to the top of the plurality of slide bars 53. During the movement of the lifting plate 3, the two guide frames 61 and the two guide blocks 62 limit the movement of the lifting plate 3 to ensure the stability of the lifting plate 3 during the movement. When the lifting plate 3 moves to the top of the plurality of slide bars 53, the two guide blocks 62 move to the top of the two guide frames 61 respectively. At this time, the two magnetic plates 63 will contact with the two magnetic blocks 64 and be adsorbed together with the two magnetic blocks 64. The two magnetic plates 63 and the two magnetic blocks 64 fix the position of the lifting plate 3.

When the fume absorption structure absorbs fume, the drive sleeve 112 is separated from the gear 103. When the drive rod 84 rotates, the drive sleeve 112 can be driven to rotate through the two blocks 113 and the two bayonet holes 114. Since the drive sleeve 112 is separated from the gear 103, the drive sleeve 112 will not drive the gear 103 to rotate. When cleaning the welding slag scattered on the lifting plate 3,

The staff opens the door panel on the vacuum cylinder 82, and then rotates the threaded sleeve 111. When the threaded sleeve 111 rotates, it can move on the driving rod 84, and push the driving sleeve 112 upward through the spring 116, so that the driving sleeve 112 is inserted into the inner ring of the gear 103, and the plug block 115 is inserted into the slot 117 on the gear 103. In this case, the driving sleeve 112 can drive the gear 103 to rotate through the plug block 115 and the slot 117. When the gear 103 rotates, it can also drive the gear 2 105 meshing with it to rotate, which makes the rotating shaft 104 rotate. When the rotating shaft 104 rotates, it can drive the winding wheel 106 to rotate, and the winding wheel 106 is used to reel the traction line 107. When the traction line 107 is wound around the winding wheel 106, one end of the traction line 107 can pull the movable frame 71 to move, so that the movable frame 71 moves from one end of the lifting plate 3 toward the other end of the lifting plate 3. Since the bottom surface of the slag cleaning seat 76 is in contact with the top surface of the lifting plate 3, the slag cleaning seat 76 can push the welding slag on the top surface of the lifting plate 3 toward one end of the lifting plate 3 during the movement of the movable frame 71, and make the welding slag fall onto the welding table 1 through one end of the lifting plate 3;

Furthermore, the auxiliary welding device is also provided with a trigger assembly and an execution assembly. When the driving rod 84 rotates, it can drive the eccentric wheel 121 to rotate. During the rotation process, the eccentric wheel 121 can continuously squeeze the connecting rod 124 in the trigger assembly. When the eccentric wheel 121 squeezes the connecting rod 124 in the trigger assembly, the connecting rod 124 in the trigger assembly can drive the corresponding sliding plug 123 to move, so that the air inside the outer cylinder 122 in the trigger assembly enters the outer cylinder 122 in the execution assembly through the connecting pipe 126, so that the sliding plug 123 in the execution assembly and the corresponding connecting rod 124 move. When the eccentric wheel 121 and the connecting rod 124 in the trigger assembly are connected, the connecting rod 124 in the trigger assembly can be driven to move. When the rod 124 is separated, the sliding plug 123 in the trigger assembly will be reset under the action of the corresponding spring three 125. At this time, the sliding plug 123 in the trigger assembly can extract the air inside the outer cylinder 122 in the actuator assembly, and the sliding plug 123 and the corresponding connecting rod 124 in the actuator assembly will also be reset under the action of the corresponding spring three 125. Based on the above process, with the rotation of the eccentric wheel 121, under the cooperation of the trigger assembly and the actuator assembly, the slag cleaning seat 76 can vibrate, and the vibrating slag cleaning seat 76 can push the welding slag adhered to the top surface of the lifting plate 3 away from the surface of the lifting plate 3, which is conducive to the welding slag falling off the lifting plate 3, thereby ensuring the cleaning effect of the slag cleaning structure on the welding slag;

A welding slag collection space is provided on the welding table 1. A grid plate is fixed on the top surface of the welding table 1. A detachable collection drawer is provided at the bottom of the welding table 1. When the slag cleaning seat 76 pushes the welding slag from the lifting plate 3, the welding slag can fall into the welding slag collection space on the welding table 1 through the gap on the grid plate, and finally slide into the collection drawer, which collects the welding slag. The staff only needs to clean the welding slag in the collection drawer regularly, which is convenient to operate.

The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
