Description

Integrated intelligent vehicle frame welding platform and its welding method Technical Field

[0001] This invention relates to the field of welding technology, and in particular to an integrated intelligent vehicle frame welding platform and a welding method for the integrated intelligent vehicle frame welding platform. Background Technology

[0002] In industries such as automotive and construction machinery, the chassis, as the core load-bearing structure, directly affects the safety and reliability of the product through its welding quality. Currently, the welding of large chassis mostly utilizes automated arc welding platforms, which control the welding torch movement through multi-axis linkage to achieve continuous and efficient welding operations. However, in actual welding processes, several key technical challenges still exist that affect welding quality and efficiency, hindering further improvements in welding technology. First, the welding process itself is a strong thermo-mechanical coupling process. The rapid movement of the arc heat source and the dynamic changes in the molten pool can induce harmful, "bell-ringing" vibrations in the chassis structure at specific frequencies. This structural vibration not only interferes with the precise alignment of the welding torch, causing weld trajectory deviation, but also causes violent fluctuations in the molten pool, resulting in defects such as poor weld formation, porosity, and slag inclusions. Second, the stability of the welding arc is another crucial factor in ensuring welding quality. Maintaining a constant arc length (i.e., the distance between the welding nozzle and the workpiece) is essential. However, under the action of welding thermal cycling, the weld and its near-weld zone metal undergo thermal expansion and contraction, causing momentary bulges or depressions on the surface of the welded area, thereby altering the arc length. Fluctuations in arc length directly affect arc heat power and droplet transfer, and in severe cases can lead to arc breakage, undercut, or burn-through.

[0003] Therefore, we propose an integrated intelligent vehicle frame welding platform and its welding method to solve this problem. Summary of the Invention

[0012] This invention also provides a welding method for an integrated intelligent vehicle frame welding platform, applied to the aforementioned integrated intelligent vehicle frame welding platform, comprising the following steps: S1: placing the vehicle frame to be welded on the top of the groove frame; starting the second motors on both sides to drive the second sliding plate and the chamfer plate to move towards each other, thereby laterally positioning the left and right sides of the vehicle frame; then starting the first motors on both sides to drive the first lead screw to rotate, causing the clamping plates on both sides to move down, completing the vertical positioning of the top of the vehicle frame; after positioning, starting the fourth motor to drive the third lead screw to rotate, causing the T-plate and the connecting plate to reciprocate longitudinally; simultaneously starting the third motor to drive the fourth lead screw to rotate, causing the arc frame to reciprocate laterally; then connecting the power supply interface and the wire feeder. Welding wire is fed by a wire feeder and an electric arc is generated. The arc acts on the frame through the welding nozzle, thus completing multi-directional welding operations. S2: During welding, the frame will generate harmful vibrations at a specific frequency, similar to the sound of a bell. This vibration is transmitted to the mass blocks on both sides. Under the synergistic action of the thin and thick springs, the mass blocks move up and down with the vibration, driving the slotted column to move synchronously. Through the guiding action of the inclined arc groove inside the vertical plate, the up and down movement of the slotted column is converted into the longitudinal reciprocating motion of the vertical plate, which in turn drives the semi-arc plate and ratchet to move in the same direction. When the two ratchets move backward, they drive the corresponding pinion to rotate. When they move forward, under the action of the second spring, the ratchet and pinion disengage, and the pinion stops rotating. As the mass blocks continue to resonate... The pinion rotates intermittently and at varying speeds according to the vibration intensity; this rotation further drives the large gear to rotate, thus converting the vertical motion energy generated by the vibration into rotational kinetic energy, which is stored in the larger flywheel to provide energy reserves for subsequent vibration damping; S3: The vertical rotation of the first bevel gear drives the second bevel gear and the horizontal shaft to rotate laterally, which in turn drives the disk and the eccentric cam to rotate; the rotation of the eccentric cam pushes the damping top plate upward, so that it abuts against the bottom of the frame, thereby counteracting the downward vibration force; considering that there is a response delay in the damping top plate in the early stage of vibration, the angle of the eccentric cam needs to be adjusted according to the standard thickness of the frame before welding to shorten the initial distance between the damping top plate and the frame, thereby compensating for the lag in mechanical energy conversion. To improve vibration damping and welding quality; when welding a thicker frame, the vibration intensity increases, the flywheel speed increases accordingly, and the horizontal shaft and centrifugal frame rotate faster; under the action of centrifugal force, the third springs on both sides and the connecting rods move closer to each other, so that the eccentric cams on both sides gradually move closer while rotating; since the bottom of the vibration damping top plate is arc-shaped, the approach of the eccentric cams further shortens the distance between the vibration damping top plate and the frame, thereby realizing adaptive adjustment of the vibration damping compensation amount according to the vibration intensity, significantly improving the stability of the welding process; S4: The increase in surface temperature of the weld during welding may cause material bulging, shortening the arc length and affecting the welding quality; therefore, low expansion metal sheets of tile alloy and high expansion metal sheets of nickel alloy are used to respond to temperature;When the temperature is too high, the nickel alloy high-expansion metal sheet bends downwards, causing the return frame and the second toothed plate to move downwards. This, in turn, through the main gear transmission, causes the first toothed plate and the fillet plate to move the welding nozzle upwards, increasing the distance between the welding nozzle and the frame, maintaining a constant arc length, and avoiding welding defects caused by distance changes. Simultaneously, as the second toothed plate moves upwards, the fourth spring pushes the inverted convex plate and the inner plate away from each other, thereby moving the resistance block, reducing the resistance value of the first power supply, increasing the output power of the cooling tube, and accelerating the cooling of the weld surface. This prompts the nickel alloy high-expansion metal sheet to quickly return to its initial state, reducing unnecessary displacement of the welding nozzle, further ensuring arc length stability, and ultimately improving the reliability of the welding process and overall work efficiency.

[0013] Compared with existing technologies, this invention provides an integrated intelligent vehicle frame welding platform and its welding method, which has the following beneficial effects: 1. Harmful vibrations generated during welding are collected by a mass block and then collected by a flywheel, which acts as a force to counteract the vibrations, reducing the impact of vibrations on welding quality; 2. The centrifugal frame causes the eccentric cam to move to one side as the vibration frequency increases, reducing the distance between the vibration damping plate and the workpiece, eliminating the energy lag caused by the mechanical structure, and better counteracting each vibration; 3. The thermal deformation equal arc structure allows for real-time adjustment of the arc length between the workpiece according to the temperature of the welding surface, while accelerating the cooling of the welding surface to quickly restore it to the equal arc distance, improving welding quality while reducing the labor intensity of workers.

[0014] This invention is rationally designed. The integrated intelligent vehicle frame welding platform and its welding method, through a resonant energy conversion mechanism, can recover the mechanical energy of the vehicle frame's vertical vibration and convert it into rotational kinetic energy for active vibration suppression control without external power supply, effectively reducing energy costs. The active vibration suppression mechanism can offset harmful vibrations generated during welding in real time, significantly reducing the negative impact of vibration on weld quality. The hot deformation arc structure reliably maintains the welding arc length as constant as possible by dynamically adjusting the welding nozzle height, thereby improving weld formation quality and process stability.

[0025] This invention also provides a welding method for an integrated intelligent vehicle frame welding platform, applied to the aforementioned integrated intelligent vehicle frame welding platform, comprising the following steps: S1: placing the vehicle frame to be welded on the top of the groove frame 16; starting the second motors 29 on both sides to drive the second sliding plate 26 and the chamfer plate 2 to move towards each other, thereby laterally positioning the left and right sides of the vehicle frame; then starting the first motors 22 on both sides to drive the first lead screw 21 to rotate, causing the clamping plates 210 on both sides to move down, completing the vertical positioning of the top of the vehicle frame; after positioning, starting the fourth motor 131 to drive the third lead screw 31 to rotate, causing the T-plate 3 and the connecting plate 14 to reciprocate longitudinally; simultaneously starting the third motor 34 to drive the fourth lead screw 33 to rotate, causing the arc frame 8 to reciprocate laterally; Next, the power supply interface 831 and wire feeder 832 are connected. The wire feeder 832 delivers welding wire and generates an electric arc. The electric arc acts on the frame through the welding nozzle 834, thereby completing the multi-directional welding operation. S2: During the welding process, the frame will generate harmful vibrations at a specific frequency similar to striking a bell. This vibration is transmitted to the mass blocks 44 on both sides. The mass blocks 44 move up and down with the vibration under the synergistic action of the thin spring 42 and the thick spring 43, and drive the slot column 441 to move synchronously. Through the guiding action of the inclined arc groove 411 inside the vertical plate 47, the up and down movement of the slot column 441 is converted into the longitudinal reciprocating motion of the vertical plate 47, which in turn drives the semi-arc plate 5 and the ratchet 52 to move in the same direction. When the two ratchet 52 move backward, they will drive the corresponding pinion 57 to rotate. When they move forward, they will drive the corresponding pinion 57 to rotate. During operation, under the action of the second spring 55, the ratchet 52 disengages from the pinion 57, and the pinion 57 stops rotating. As the mass block 44 continues to resonate, the pinion 57 rotates intermittently and at varying speeds according to the vibration intensity. This rotation further drives the large gear 59 to rotate, thereby converting the vertical motion energy generated by the vibration into rotational kinetic energy, which is stored in the larger flywheel 510, providing energy reserves for subsequent vibration suppression. S3: The vertical rotation of the first bevel gear 581 drives the second bevel gear 63 and the horizontal shaft 62 to rotate laterally, which in turn drives the disk 74 and the eccentric cam 61 to rotate. The rotation of the eccentric cam 61 pushes the vibration suppression top plate 17 upward, so that it abuts against the bottom of the frame, thereby counteracting the downward vibration force. Considering the initial vibration suppression top plate... Plate 17 exhibits a response delay, requiring adjustment of the eccentric cam 61 angle based on the standard frame thickness before welding to shorten the initial distance between the vibration damping plate 17 and the frame. This compensates for the lag in mechanical energy conversion, improving vibration damping effect and welding quality. When welding a thicker frame later, the vibration intensity increases, and the flywheel 510 speed increases accordingly, driving the transverse shaft 62 and centrifugal frame 7 to rotate faster. Under centrifugal force, the third springs 75 and connecting rods 72 on both sides move closer together, causing the eccentric cams 61 on both sides to gradually approach each other while rotating. Since the bottom of the vibration damping plate 17 is arc-shaped, the approach of the eccentric cams 61 further shortens the distance between the vibration damping plate 17 and the frame, thereby achieving adaptive adjustment of the vibration damping compensation amount according to the vibration intensity, significantly improving the stability of the welding process.S4: During welding, an increase in weld surface temperature may cause material bulging, shortening the arc length and affecting weld quality. Therefore, a low-expansion metal sheet 843 made of nickel alloy and a high-expansion metal sheet 842 of nickel alloy are used to respond to temperature changes. When the temperature is too high, the high-expansion metal sheet 842 of nickel alloy bends downwards, causing the return frame 844 and the second toothed plate 854 to move downwards. This, in turn, is transmitted through the main gear 853, causing the first toothed plate 851 and the fillet plate 85 to move the welding nozzle 834 upwards, thereby increasing the distance between the welding nozzle 834 and the frame and maintaining a constant arc length. This avoids welding defects caused by changes in distance. Simultaneously, when the second toothed plate 854 moves upward, under the action of the fourth spring 826, it pushes the inverted convex plate 825 away from the inner plate 824, thereby moving the resistor block 827, reducing the resistance value of the first power supply 822, increasing the output power of the cooling tube 821, and accelerating the cooling of the weld surface. This prompts the nickel alloy high-expansion metal sheet 842 to quickly return to its initial state, reducing unnecessary displacement of the welding nozzle 834, further ensuring the stability of the arc length, and ultimately improving the reliability of the welding process and overall work efficiency.

[0026] In this embodiment, during the specific implementation process, the frame to be welded is placed on top of the groove frame 16. The second motors 29 on both sides are activated, driving the second sliding plate 26 and the chamfered plate 2 to move towards each other, thereby laterally positioning the left and right sides of the frame. Then, the first motors 22 on both sides are activated, driving the first lead screw 21 to rotate, causing the clamping plates 210 on both sides to move downwards, completing the vertical positioning of the top of the frame. After positioning, the fourth motor 131 is activated, driving the third lead screw 31 to rotate, causing the I-plate 3 and the connecting plate 14 to reciprocate longitudinally. Simultaneously, the third motor 34 is activated, driving the fourth lead screw 33 to rotate, causing the arc frame 8 to reciprocate laterally. Next, the power interface 831 and the wire feeder 832 are connected. The wire feeder 832 delivers welding wire and generates an electric arc, which acts on the frame through the welding nozzle 834, thereby completing the multi-directional welding operation. During the welding process, the frame will generate harmful vibrations at a specific frequency, similar to the sound of a bell. The vibration is transmitted to the two mass blocks 44 on both sides. Under the synergistic action of the thin spring 42 and the thick spring 43, the mass blocks 44 move up and down with the vibration, driving the slotted column 441 to move synchronously. Through the guiding action of the inclined arc groove 411 inside the vertical plate 47, the up and down movement of the slotted column 441 is converted into the longitudinal reciprocating motion of the vertical plate 47, which in turn drives the semi-arc plate 5 and the ratchet 52 to move in the same direction. When the two ratchet 52 move backward, they drive the corresponding pinion 57 to rotate; when they move forward, under the action of the second spring 55, the ratchet 52 disengages from the pinion 57, and the pinion 57 stops rotating. As the mass blocks 44 continue to resonate, the pinion 57 rotates intermittently and at varying speeds according to the vibration intensity. This rotation further drives the large gear 59 to rotate, thereby converting the up and down motion energy generated by the vibration into rotational kinetic energy, which is stored in the larger flywheel 510, providing energy reserves for subsequent vibration suppression. Subsequently, the vertical rotation of the first bevel gear 581 drives the second bevel gear 63 and the horizontal shaft 62 to rotate laterally, which in turn drives the disc 74 and the eccentric cam 61 to rotate. The rotation of the eccentric cam 61 pushes the vibration damping top plate 17 upward, so that it abuts against the bottom of the frame, thereby counteracting the downward vibration force. Considering that the vibration damping top plate 17 has a response delay in the early stage of vibration, the angle of the eccentric cam 61 needs to be adjusted according to the standard thickness of the frame before welding to shorten the initial distance between the vibration damping top plate 17 and the frame, thereby compensating for the lag in mechanical energy conversion and improving the vibration damping effect and welding quality. When welding a thicker frame later, the vibration intensity increases, and the speed of the flywheel 510 increases accordingly, driving the horizontal shaft 62 and the centrifugal frame 7 to rotate faster. Under the action of centrifugal force, the third springs 75 on both sides and the connecting rod 72 move closer to each other, so that the eccentric cams 61 on both sides gradually move closer together while rotating. Because the bottom of the vibration damping top plate 17 is arc-shaped, the proximity of the eccentric cam 61 further shortens the distance between the vibration damping top plate 17 and the frame, thereby enabling adaptive adjustment of the vibration damping compensation amount according to the vibration intensity and significantly improving the stability of the welding process. In addition, the increased surface temperature of the weld during welding may cause material bulging, shortening the arc length and affecting the welding quality.To address this, a low-expansion metal sheet 843 of alloy and a high-expansion metal sheet 842 of nickel alloy are used to respond to temperature changes. When the temperature is too high, the high-expansion metal sheet 842 of nickel alloy bends downward, causing the return frame 844 and the second toothed plate 854 to move downward. This, in turn, is transmitted through the main gear 853, causing the first toothed plate 851 and the rounded corner plate 85 to move the welding nozzle 834 upward, thereby increasing the distance between the welding nozzle 834 and the frame, maintaining a constant arc length, and avoiding welding defects caused by changes in distance. Simultaneously, when the second toothed plate 854 moves upward, under the action of the fourth spring 826, it pushes the inverted protrusion plate 825 and the inner plate 824 away from each other, thereby causing the resistor block 827 to move, reducing the resistance value of the first power supply 822, increasing the output power of the cooling tube 821, and accelerating the cooling of the weld surface. This prompts the nickel alloy high-expansion metal sheet 842 to quickly return to its initial state, reducing unnecessary displacement of the welding nozzle 834, further ensuring the stability of the arc length, and ultimately improving the reliability of the welding process and overall work efficiency. Through the resonant energy conversion mechanism, the mechanical energy of the frame's vertical vibration can be recovered and converted into rotational kinetic energy for active vibration suppression control without external power supply, effectively reducing energy costs. The active vibration suppression mechanism can offset the harmful vibrations generated during the welding process in real time, significantly reducing the negative impact of vibration on weld quality. The hot deformation arc structure reliably maintains a constant welding arc length by dynamically adjusting the welding nozzle height, thereby improving weld formation quality and process stability.

8. A welding method for an integrated intelligent vehicle frame welding platform, applied to the integrated intelligent vehicle frame welding platform as described in claim 7, characterized in that, Includes the following steps: S1: Place the frame to be welded on top of the groove frame; start the second motors on both sides to drive the second sliding plate and the chamfer plate to move towards each other, thereby laterally positioning the left and right sides of the frame; then start the first motors on both sides to drive the first lead screw to rotate, causing the clamping plates on both sides to move down, completing the vertical positioning of the top of the frame; after positioning, start the fourth motor to drive the third lead screw to rotate, causing the T-plate and the connecting plate to reciprocate longitudinally; at the same time, start the third motor to drive the fourth lead screw to rotate, causing the arc frame to reciprocate laterally; then connect the power interface and the wire feeder, and the wire feeder delivers welding wire and generates an arc, which acts on the frame through the welding nozzle, thereby completing the multi-directional welding operation; S2: During the welding process, the frame will produce a specific frequency similar to the sounding of a bell. Harmful vibrations are transmitted to the mass blocks on both sides. These mass blocks, under the combined action of the thin and thick springs, move up and down with the vibrations, causing the slotted column to move synchronously. Guided by the inclined arc groove inside the vertical plate, the up-and-down motion of the slotted column is converted into the longitudinal reciprocating motion of the vertical plate, which in turn drives the semi-arc plate and ratchet to move in the same direction. When the two ratchets move backward, they drive the corresponding pinion to rotate. When they move forward, under the action of the second spring, the ratchet disengages from the pinion, and the pinion stops rotating. As the mass blocks continue to resonate, the pinion rotates intermittently and at varying speeds according to the vibration intensity. This rotation further drives the large gear to rotate, thus converting the up-and-down motion energy generated by the vibrations into rotational kinetic energy, which is stored in the larger flywheel. Provides energy reserves for subsequent vibration damping; S3: The vertical rotation of the first bevel gear drives the second bevel gear and the horizontal shaft to rotate laterally, which in turn drives the disc and the eccentric cam to rotate; the rotation of the eccentric cam pushes the damping top plate to move upward, so that it abuts against the bottom of the frame, thereby counteracting the downward vibration force; considering that the damping top plate has a response delay in the early stage of vibration, the angle of the eccentric cam needs to be adjusted according to the standard thickness of the frame before welding to shorten the initial distance between the damping top plate and the frame, so as to compensate for the lag in mechanical energy conversion and improve the damping effect and welding quality; when welding a thicker frame laterally, the vibration intensity increases, the flywheel speed increases accordingly, and drives the horizontal shaft and the centrifugal frame to rotate faster; under the action of centrifugal force, the third springs on both sides and the connecting rods move closer to each other, so that the eccentric cams on both sides rotate simultaneously As the vibration damping top plate gradually approaches, the approach of the eccentric cam further shortens the distance between the vibration damping top plate and the frame, thereby achieving adaptive adjustment of the vibration damping compensation amount according to the vibration intensity, significantly improving the stability of the welding process; S4: During welding, the surface temperature of the weld may rise, causing the material to bulge, shortening the arc length, and affecting the welding quality; To address this, a low-expansion metal sheet of nickel alloy and a high-expansion metal sheet of nickel alloy are used to respond to the temperature; When the temperature is too high, the high-expansion metal sheet of nickel alloy bends downward, causing the return frame and the second toothed plate to move downward, and then through the main gear transmission, the first toothed plate and the rounded corner plate drive the welding nozzle upward, thereby increasing the distance between the welding nozzle and the frame, maintaining a constant arc length, and avoiding welding defects caused by changes in distance;Simultaneously, as the second toothed plate moves upward, the fourth spring pushes the inverted convex plate away from the inner plate, thereby causing the resistor block to move, reducing the resistance value of the first power supply, increasing the output power of the cooling tube, and accelerating the cooling of the weld surface. This prompts the nickel alloy high-expansion metal sheet to quickly return to its initial state, reducing unnecessary displacement of the welding nozzle, further ensuring the stability of the arc length, and ultimately improving the reliability of the welding process and overall work efficiency.
