Description

Technical Field

[0001] The invention relates to the technical field of welding, and in particular to a welding system for a front support of an axle air suspension. Background Art

[0002] Suspension, also known as suspension, is the general term for all force-transmitting connecting devices between the frame and the axle of a semi-trailer. It is used to transmit the force and torque acting between the wheels and the frame, buffer the impact force transmitted to the frame or body by the road surface, and reduce the vibration caused thereby, so as to ensure that the car can run smoothly. Among them, air suspension is also called airbag suspension. Its most notable feature is the airbag-type air spring. Compared with other suspensions, the air suspension has better buffering force, which can effectively protect the goods and improve driving comfort. It is currently mainly used in the transportation of precision instruments and hazardous chemicals. The front support in the air suspension is an indispensable and important component in the suspension system. As a load-bearing part, it bears different forms of force fed back to the body under various working conditions and different road surfaces, and transfers the mass of the whole vehicle from the frame to the suspension system. At the same time, it is also necessary to transfer the driving force and driving resistance to the body. The quality is directly related to the safety, stability and carrying capacity of the whole vehicle. At present, most of such components on the market are welded parts.

[0003] During the production process of the front support of the air suspension, it is necessary to weld components such as reinforcing ribs, connecting bent plates and connecting seats on the main board. The shapes of various components are irregular, and it is difficult for traditional fixtures to stably clamp the components. At the same time, manual welding is used, and the welding stability and accuracy are difficult to control, which depends on the technical level and experience of the welders. The laser automatic welding method can ensure the welding accuracy, but when clamping the workpiece, since welding uses high temperature to melt the welding material to connect the weld, the workbench and fixture place and clamp the workpiece for a long time, which will cause thermal deformation, affecting the welding accuracy of the front support. The various components are welded on the main board in turn. The main board is heated more, and the size may change in the early and late stages of welding, resulting in a decrease in the welding accuracy of the later welded components. Therefore, we propose an axle air suspension front support welding system, which can cool the workbench, fixture and workpiece during the welding process to reduce their thermal deformation and ensure welding accuracy.

[0046] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] like Figures 1 to 7 As shown, this embodiment proposes an axle air suspension front support welding system, including a frame 1, a workbench 2, a welding robot arm 3 and a clamping robot arm 4, and also includes a cooling bin 5, a water cooler 6 and an air cooling mechanism. Compared with the axle air suspension front support welding equipment in the prior art, the present invention realizes automatic welding of the front support through the rotation of the clamping robot arm 4, the welding robot arm 3 and the workbench 2, and at the same time, cold water is transported to the interior of the cooling bin 5 through the water cooler 6, and the vacuum pump 101 supplies air to the interior of the cooling bin 5, so that the cold air is blown to the workbench 2 and the workpiece through the air cooling pipe 102, thereby reducing the deformation of the workbench 2 and the workpiece and ensuring the welding accuracy. At the same time, the air cooling pipe 102 blows air to the workbench 2, and the collection box 201 sucks air to the workbench 2, so that the welding slag passes through the collection box 201 and enters the interior of the temporary storage box 202 for collection, and the welding slag can be cleaned, thereby further improving the welding quality.

[0048] like Figures 1 to 6As shown, the cooling bin 5 is arranged on the frame 1, the workbench 2 is rotatably arranged on the top of the cooling bin 5, an installation cavity is arranged inside the cooling bin 5, a motor 7 is arranged inside the installation cavity, the center of the workbench 2 is arranged at the output end of the motor 7, to ensure the stability of the workbench 2 when rotating, a support seat 8 is arranged at the bottom of the workbench 2, and a ball 9 is rotatably arranged at the bottom of the support seat 8, and the ball 9 is in contact with the top of the cooling bin 5. A clamping mechanism is arranged on the workbench 2. For example, flat-nose pliers can be used to clamp the mainboard of the front support on the workbench 2. The motor 7 can drive the workbench 2 to rotate, and the angle of the mainboard can be adjusted to clamp the mechanical arm 4. A clamp is provided at the end, and a welding head and a wire feeding mechanism are provided at the end of the welding robot arm 3. The ends of the clamping robot arm 4 and the welding robot arm 3 can move freely and are equipped with visual sensors. The clamping robot arm 4 clamps the component to be welded and presses it against the appropriate position of the main board. The welding robot arm 3 welds the weld between the component to be welded and the main board. The clamping robot arm 4 and the welding robot arm 3 are prior arts known in the art and will not be elaborated here. When the motor 7 drives the workbench 2 to rotate, the support seat 8 and the ball 9 stably support the workbench 2. At the same time, the rotation of the ball 9 can reduce the resistance to the rotation of the workbench 2.

[0049] like Figure 1 and Figure 4 As shown, the water cooler 6 is arranged inside the frame 1, and the water inlet and the water outlet of the water cooler 6 are connected with the cooling bin 5, and are used to transport cold water to the inside of the cooling bin 5. The water cooler 6 can produce cold water and transport the cold water to the inside of the cooling bin 5. The connection position between the water inlet of the water cooler 6 and the cooling bin 5 is in the upper middle position of the cooling bin 5, and the water level in the cooling bin 5 is also in the upper middle position. The inside of the cooling bin 5 can be cooled by cold water, and the low temperature generated in the cooling bin 5 can be transmitted to the workbench 2 to cool the workbench 2.

[0050] like Figure 1 and Figure 4As shown, the air cooling mechanism uses the cold air inside the cooling chamber 5 to cool the workbench 2 and the workpiece. The air cooling mechanism includes a vacuum pump 101 and an air cooling pipe 102. The vacuum pump 101 is arranged inside the frame 1. The vacuum pump 101 is connected to the cooling chamber 5 through an air supply pipe 308. The air cooling pipe 102 is connected to the cooling chamber 5. The air cooling pipe 102 is connected to a plurality of nozzles 103. The nozzles 103 face the workbench 2. The vacuum pump 101 supplies air to the interior of the cooling chamber 5 through the air supply pipe 308. The air outlet of the air supply pipe 308 extends into the interior of the cold water. The air enters the interior of the cold water and fills the cold water. The cold air is formed by the contact between the clamps 102 and the workbench 2, and the cold air is blown toward the workbench 2 through the air cooling pipe 102 and the nozzle 103, so as to cool the workbench 2, the mainboard clamped on the workbench 2, the clamping robot arm 4 and the workpiece clamped thereon, thereby reducing the deformation of the workpiece and the workbench 2 under the high temperature of welding, thereby ensuring the welding accuracy. In order to cool the clamp on the clamping robot arm 4, an air cooler 10 is provided on the clamping robot arm 4, and the air cooler 10 blows air toward the position where the clamping robot arm 4 clamps the workpiece, thereby assisting in cooling the clamp on the clamping robot arm 4 and the workpiece, thereby further reducing the deformation of the workpiece.

[0051] like Figures 1 to 4 As shown, in order to clean the welding slag generated by welding, it also includes a welding slag collecting component, which includes a collecting box 201 and a temporary storage box 202. The collecting box 201 is arranged on a side of the cooling chamber 5 away from the air cooling pipe 102. The collecting box 201 is provided with a collecting port, and the temporary storage box 202 is arranged inside the frame 1. The temporary storage box 202 is connected with the collecting box 201 through the collecting pipe, and the temporary storage box 202 is connected with the exhaust port of the vacuum pump 101. A dustproof net is provided at the connection position between the vacuum pump 101 and the temporary storage box 202 to prevent dust from entering the vacuum pump 101. The vacuum pump 101 sucks air into the temporary storage box 202 to evacuate the interior of the temporary storage box 202, thereby generating suction at the collecting box 201, and cooperating with the air cooling pipe 102 to form an airflow, thereby reducing dust and impurities at the welding position, and at the same time, the welding slag on the workbench 2 is sucked into the collection box 201 and enters the temporary storage box 202 for collection, and the welding slag in the temporary storage box 202 can be cleaned regularly.

[0052] like Figures 4 to 5As shown, in order to improve the effect of cleaning welding slag, a boosting mechanism is also included, which includes a boosting chamber 301, a movable plate 302, an air inlet pipe 303 and an air outlet pipe 304. The boosting chamber 301 is arranged inside the frame 1, and the movable plate 302 is movably arranged inside the boosting chamber 301. The movable plate 302 and the boosting chamber 301 are in sealed sliding cooperation. An electric cylinder 305 is arranged on the frame 1, and a driving plate 306 is arranged at the output end of the electric cylinder 305. The movable plate 302 is connected to the driving plate 306 through a driving shaft. Two air inlet pipes 303 are arranged on both sides of the boosting chamber 301, and a one-way valve 307 is arranged on the air inlet pipe 303. The two air inlet pipes 303 are connected to the outside world. Two air outlet pipes 304 are arranged on both sides of the boosting chamber 301. A one-way valve 307 is provided on the air outlet pipe 304. The two air outlet pipes 304 are connected to the air supply pipe 308. The electric cylinder 305 can drive the movable plate 302 to move back and forth inside the pressurized chamber 301. When the movable plate 302 moves to one side, the pressure on the side of the moving direction of the movable plate 302 increases, and the air on this side is discharged through the one-way valve 307 and the air outlet pipe 304 and enters the interior of the air supply pipe 308, thereby increasing the air pressure in the cooling chamber 5 from the air supply pipe 308, increasing the blowing force of the air cooling pipe 102, and improving the cleaning effect. The pressure on the side away from the moving direction of the movable plate 302 is reduced, and the outside air is sucked in through the one-way valve 307 and the air inlet pipe 303 to supplement the air in the pressurized chamber 301, thereby realizing continuous air supply to the inside of the air supply pipe 308 and ensuring the blowing intensity of the air cooling pipe 102.

[0053] like Figures 4 to 5As shown, in order to reduce the influence of moisture on welding, a dewatering component is also included, and the dewatering component includes a dewatering box 401 and a water-absorbing sponge 402. The dewatering box 401 is arranged on the cooling bin 5, and the bottom of the dewatering box 401 is connected with the cooling bin 5 through a plurality of through holes. The water-absorbing sponge 402 is arranged inside the dewatering box 401. The air enters the interior of the cooling bin 5 and is cooled by cold water. Then the cold wind enters the interior of the dewatering box 401. The water-absorbing sponge 402 absorbs the moisture in the cold wind to prevent the moisture from being blown to the welding position and affecting the welding. At the same time, in order to ensure the water absorption effect of the water-absorbing sponge 402, an extrusion plate 403 is movably arranged inside the dewatering box 401. The extrusion plate 403 is connected to the cooling bin 5 by a connecting rod and a driving rod. The movable plate 306 is connected, and the extrusion plate 403 is in contact with the side of the water-absorbing sponge 402 away from the through hole. When the electric cylinder 305 drives the movable plate 302 to move back and forth inside the boosting chamber 301, it also drives the extrusion plate 403 to move back and forth inside the dewatering tank 401. The extrusion plate 403 squeezes the water-absorbing sponge 402 during the movement toward the cooling chamber 5, squeezes the water inside the water-absorbing sponge 402, and the water flows back to the inside of the cooling chamber 5 through the through hole, reducing the waste of water resources. At the same time, the water absorption effect of the water-absorbing sponge 402 is ensured, and the water is prevented from being discharged through the air-cooling pipe 102. The height of the through hole is higher than the water surface in the cooling chamber 5, thereby preventing cold water from directly entering the inside of the dewatering tank 401.

[0054] The working principle or use process of the axle air suspension front support welding system is as follows:

[0055] First, clamp the mainboard on the workbench 2, clamp the parts to be welded by the clamping robot 4 and place them in the welding position, and move the welding robot 3 to the welding position for automatic welding. During the welding process, the water cooler delivers cold water to the inside of the cooling bin 5, and at the same time, the vacuum pump 101 delivers air to the inside of the cooling bin 5. The cold air is cooled by the cold water, and the cold air is blown to the workbench 2 and the workpiece through the air cooling pipe 102 to cool them. At the same time, the vacuum pump 101 sucks air into the temporary storage box 202 and the collection box 201 to suck the welding slag and dust into the temporary storage box 2 02's internal collection, during this process, the electric cylinder 305 drives the driving plate 306 to move, thereby driving the squeezing plate 403 and the moving plate 302 to move back and forth, the water-absorbing sponge 402 absorbs the moisture in the cold air, and the squeezing plate 403 squeezes the moisture inside the water-absorbing sponge 402 and flows it back to the interior of the cooling bin 5, the moving plate 302 moves back and forth, sucks air into the interior of the boosting bin 301, and at the same time sends the air inside the boosting bin 301 into the air supply pipe 308 and the interior of the cooling bin 5, thereby increasing the blowing force of the air-cooling pipe 102 and ensuring the cleaning effect.

[0056] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
