Description

Technical Field

[0001] The present invention relates to the technical field of automobile manufacturing, and in particular to a vehicle frame assembly welding error prevention device. Background Art

[0002] Frame assembly welding is a key process in the automobile manufacturing process, which connects the various components that make up the frame assembly, such as longitudinal beams, cross beams, connecting plates, etc., into an integral structure through welding. The frame assembly is the core load-bearing component of the automobile, equivalent to the "skeleton" of the vehicle. It needs to support major components such as the engine, gearbox, and body, and withstand various loads during driving, such as traction, braking force, bumps and impacts, etc. Therefore, the structural strength, rigidity and stability of the frame assembly are directly related to the driving safety, handling performance and service life of the vehicle.

[0003] In the field of automobile manufacturing, the frame assembly is the core load-bearing part of the entire vehicle, and its welding quality directly determines the safety and service life of the vehicle. Currently, there are three major technical pain points in the welding of the frame assembly: First, the front and back welding requires manual release of the fixation and flipping of the workpiece. Frequent clamping causes the welding reference to shift, resulting in cumulative errors. Moreover, the welding surface is prone to cracks or deformation due to collision during flipping, and the qualified rate is low. Second, the spatter impurities and smoke generated during the welding process adhere to the surface of the workpiece. If not cleaned in time, it will cause defects such as cold welds and slag inclusions in the secondary welding. The traditional manual cleaning method is time-consuming and accounts for a high proportion of time, which seriously affects production efficiency. Third, welding quality inspections are mostly post-spot checks, and it is difficult to detect weld defects in real time. Once problems occur in batches, the rework cost is extremely high, causing huge economic losses to automobile manufacturers. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the existing technology has the disadvantages of large turning and clamping errors, untimely cleaning affecting welding quality, and insufficient real-time detection. For this reason, we propose a frame assembly welding error prevention device.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical solution: a frame assembly welding error prevention device, comprising a base, a table top fixedly connected to the interior of the base, mounting plates fixedly connected to both sides of the base, two circular frames arranged between the two mounting plates, an inner lining plate fixedly connected between the two circular frames, a wind plate commonly installed on the tops of the two mounting plates, and a detection device arranged on the top of the base;

[0006] A lifting and rotating mechanism is installed inside the mounting plate. The lifting and rotating mechanism enables the circular frame to move upward and then flip 180 degrees to flip the welding surface of the inner lining plate fixed to the frame assembly, and reduces welding residues on the surface of the frame assembly through the effect of gravity during flipping and tilting.

[0007] A wind cleaning mechanism, the wind cleaning mechanism being in transmission connection with the lifting and rotating mechanism, so that when the lifting and rotating mechanism moves up and down, the wind plate is driven to repeatedly deflect to generate wind force, thereby cooling the surface of the frame assembly inside the inner lining plate by wind force, and blowing away dirt on the surface of the frame assembly by wind force;

[0008] The mobile detection mechanism is connected to the wind cleaning mechanism in a transmission manner so that when the frame assembly to which the inner lining plate is fixed is raised and lowered, the detection device is driven to be raised and lowered synchronously. At the same time, the detection device moves horizontally when it rises, so as to move horizontally along the side of the frame assembly for real-time detection.

[0009] Preferably, the lifting and rotating mechanism:

[0010] The top of the gear train is fixedly provided with a toothed plate, and the toothed plate is fixedly provided with a toothed plate, and the toothed plate is fixedly provided with a toothed plate at the bottom.

[0011] Preferably, the wind cleaning mechanism includes:

[0012] The trough plate has two ends fixedly connected to the self-retractable rod, and the trough plate is slidably connected to the surface of the raised block. The top of the trough plate is fixedly connected to a bracket plate, and a tooth groove is provided on one side of the bracket plate. The top of the mounting plate is fixedly connected to an extension rod, and a cylinder is rotatably connected between the two extension rods through an axle rod. The bottom of the cylinder is fixedly connected to the wind plate, and both sides of the cylinder are rotatably connected to a connecting rod through the extension plate. The front end of the extension rod is rotatably connected to the third gear, and the other end of the connecting rod is rotatably connected to the surface of the third gear through a rotating shaft, and the surface of the third gear is meshed with the tooth groove.

[0013] Preferably, the movement detection mechanism includes:

[0014] A long rod, one side of the base is fixedly connected to two high and low plates, the two high and low plates are of different heights, the two ends of the long rod are fixedly connected to the top of the two high and low plates, the surface of the long rod is slidably connected to a slider, the bottom of the slider is fixedly connected to the detection device, the top of the slider is fixedly connected to a rope chain, the top of the rope chain is fixedly connected to the bracket plate, and a pulley is installed on the top of the high and low plates.

[0015] Preferably, a controller is installed on the surface of the mounting plate, and a plurality of hydraulic rods are installed inside the inner lining plate, and the output ends of the hydraulic rods are fixedly connected to clamping plates.

[0016] Preferably, there are two slides, both of which are installed on the same side of the two circular frames, and the slides deflect 180 degrees when moving along the top of the U-shaped rod.

[0017] Preferably, the long rod is installed at an angle, the slider and the detection device have a certain gravity, and there is a certain distance between the initial position of the detection device and the high and low plates.

[0018] Preferably, the deflection amplitude of the wind plate is about 90° to 120°.

[0019] Technical effects and advantages of the present invention:

[0020] In the present invention, the automatic flipping of the frame assembly is achieved through the lifting and rotating mechanism, and the front and back welding can be completed without releasing the fixation. The mechanism first raises the frame assembly to a safe height, and then achieves a stable flip of 180 degrees through gear engagement and track sliding, avoiding damage to the welds and clamping errors caused by manual flipping. During the flipping process, the cooperation of the U-shaped rod and the slide plate always provides stable support, ensuring that the frame assembly is accurately reset to the welding surface after flipping, which not only solves the interference problem with the workbench during direct flipping, but also ensures the horizontality of the welding surface, significantly improving the consistency and accuracy of the front and back welding.

[0021] In the present invention, the wind cleaning mechanism is linked with the lifting and rotating mechanism to achieve synchronous cleaning and cooling during the welding process. The wind plate is deflected significantly through gear transmission and the connecting rod to form a strong airflow to sweep the surface of the frame assembly. When the frame assembly flips and rises to the position near the wind plate, the inclination angle and the wind force work together to efficiently remove welding impurities and smoke, avoiding the adhesion of impurities that affects the quality of secondary welding. At the same time, the airflow can quickly reduce the temperature of the welding area and prevent high-temperature deformation, which not only improves the working environment, but also ensures the processing accuracy of the frame assembly and reduces the subsequent cleaning process.

[0022] In the present invention, the mobile detection mechanism realizes real-time monitoring of welding quality. The detection device is linked to the wind cleaning mechanism through a rope chain. It rises and falls synchronously with the frame assembly and moves horizontally along the inclined long rod to complete a comprehensive scan of the welding surface. This design uses gravity to automatically reset without the need for additional power. It ensures that the detection range covers the entire welding surface and detects weld defects in time through a real-time feedback mechanism. The detection results are directly transmitted to the controller, which is convenient for the operator to quickly process, effectively avoiding the flow of unqualified products into the next process, reducing the rework rate, and improving the stability of production quality.

[0023] In the present invention, through the multi-mechanism linkage design, the integrated operation of "fixing - welding - detection - flipping - cleaning" is realized. The combination of hydraulic rods and splints can be adapted to different types of frame assemblies, enhancing the versatility of the equipment. Each transmission component adopts wear-resistant materials and precise guide structure to ensure long-term stability and life. Compared with the traditional step-by-step operation mode, this device reduces the manual intervention link and greatly shortens the welding cycle. At the same time, through the error-proof detection and automatic cleaning functions, it significantly improves the welding qualification rate, reduces production costs, and improves the large-scale production efficiency of automobile frame assemblies.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0032] Reference Figure 1 - Figure 6 As shown, the present invention provides a technical solution: a vehicle frame assembly welding error prevention device, comprising a base 1, a table top 2 fixedly connected to the interior of the base 1, mounting plates 3 fixedly connected to both sides of the base 1, two circular frames 4 provided between the two mounting plates 3, an inner lining plate 5 fixedly connected between the two circular frames 4, a wind plate 6 installed on the top of the two mounting plates 3, and a detection device 7 provided on the top of the base 1;

[0033] A lifting and rotating mechanism is installed inside the mounting plate 3, the wind cleaning mechanism is transmission-connected to the lifting and rotating mechanism, and the moving detection mechanism is transmission-connected to the wind cleaning mechanism.

[0034] Reference Figure 1 - Figure 5 As shown, in this embodiment: lifting and rotating mechanism:

[0035] Motor 8, motor 8 is installed at the bottom of one side of the mounting plate 3, and a first gear 9 is installed on the top and bottom of one side of the mounting plate 3. The output end of the motor 8 is fixedly connected to the first gear 9 at the bottom, and a tooth chain 10 is installed between the two first gears 9. The surface of the tooth chain 10 is fixedly connected to a raised column 11, and the surface of the raised column 11 is rotatably connected to a sleeve 12. Both sides of the sleeve 12 are fixedly connected to a self-telescopic rod 13, and the top of the sleeve 12 is fixedly connected to a raised block 14. One side of the sleeve 12 is rotatably connected to a second gear 15 through a rotating shaft, and the surface of the second gear 15 is fixedly connected to one side of the circular frame 4. The top of the base 1 is fixedly connected to a first slide bar 16 on all sides, one end of the telescopic rod 13 is slidably connected to the surface of the first slide bar 16, and two second slide bars 17 are fixedly connected to both sides of the base 1. The surface of the second slide bar 17 is slidably connected to a U-shaped rod 18, and one side of the round frame 4 is fixedly connected to a slide plate 19. The slide plate 19 is slidably connected to the surface of the U-shaped rod 18. The surface of the mounting plate 3 is fixedly connected to a U-shaped plate 20. The surface of the second gear 15 is meshed with the top of the inner diameter of the U-shaped plate 20. The frame assembly to be welded is neatly docked by the staff and placed on the top of the desktop 2 and fixed by the hydraulic rod 34. After that, the frame assembly is welded by the mechanical welding arm provided outside the device or manually. After the top surface of the frame assembly is welded, the bottom surface of the frame assembly needs to be welded. At this time, the staff starts the motor 8 to drive the first gear 9 to run. The rotation of the first gear 9 drives the tooth chain 10 to rotate clockwise, so that the raised column 11 follows the rotation of the tooth chain 10 and performs a circular movement of rising and falling. When the raised column 11 follows the rotation of the tooth chain 10 counterclockwise, the sleeve 12 is lifted upward, so that the sleeve 12 moves upward, and the self-telescopic rod 13 follows the sleeve 12 to rise and fall and slides along the surface of the first slide bar 16. At the same time, the tooth chain When the top and bottom of the raised column 11 move in a semicircular direction, the sleeve 12 will move leftward or rightward respectively. During this process, the sleeve 12 will also move along the semicircular direction following the raised column 11. At the same time, the telescopic rod 13 itself will extend and retract, automatically adjusting the position of the sleeve 12 supported by the first slide bars 16 on both sides when it moves left and right. When the sleeve 12 moves horizontally, it will also drive the second gear 15 and the circular frame 4 to move synchronously. The slide plate 19 is sleeved on the surface of the U-shaped rod 18, so that the U-shaped rod 18 will also slide along the surface of the second slide bar 17 to adjust its own position following the horizontal movement of the sleeve 12.

[0036] When the sleeve 12 is in a straight rise, the sleeve 12 drives the second gear 15 and the circular frame 4 to move upward synchronously, so that the slide plate 19 slides upward along the surface of the U-shaped rod 18. When the raised column 11 follows the toothed chain 10 to rotate to the top semicircle and continues to rotate, the sleeve 12 will follow the top track of the toothed chain 10 to move in a semicircular manner. At this time, the sleeve 12 is supported by the self-telescopic rod 13 sliding on the surface of the first slide bar 16 on both sides. Since the second gear 15 has followed the sleeve 12 to move to the top area of ​​the U-shaped plate 20 at this time, when the sleeve 12 moves in a semicircular manner along the top track of the toothed chain 10, the second gear 15 will also move synchronously, which makes the second gear 15 move synchronously when the circular frame 4 moves to the top position. The second gear 15 will be meshed with the U-shaped plate 20, and the semicircular movement of the second gear 15 will mesh with the U-shaped plate 20, causing the second gear 15 to rotate. The slide plate 19 will also move to the top semicircle of the U-shaped rod 18, and the second gear 15 will rotate 180 degrees to drive the circular frame 4 and the inner lining plate 5 to turn over synchronously. Then, the slide plate 19 will slide semicircularly along the top of the U-shaped plate 20, always supporting one end of the circular frame 4. After the circular frame 4 and the inner lining plate 5 are turned over 180 degrees, the slide plate 19 will slide from one side of the U-shaped rod 18 to the other side. At this time, the circular frame 4 and the inner lining plate 5 have been deflected 180 degrees, and the top surface of the frame assembly inside the inner lining plate 5 has rotated to the bottom, and the inner lining plate 5 will be in a position away from the desktop 2.

[0037] After that, the motor 8 continues to run, causing the circular frame 4 and the inner lining plate 5 to descend linearly, and the inner lining plate 5 is moved to the surface of the table top 2. Then, the staff welds the bottom surface of the frame assembly inside the inner lining plate 5 to complete the welding work of the top and bottom surfaces of the frame assembly. Finally, the motor 8 runs in the reverse direction, causing the circular frame 4 to rise and then deflect in the reverse direction to reset the slide plate 19 to the other side of the U-shaped rod 18, so that the frame assembly is flipped to the initial position. The welded frame assembly is then taken out of the inner lining plate 5, completing the welding work on the front and back sides of the frame assembly. After that, a new frame assembly is placed in and the above operations are carried out.

[0038] After the top welding of the frame assembly is completed by fixing the frame assembly with the inner lining plate 5, it is first raised away from the table top 2 to the top position of the mounting plate 3, and then the inner lining plate 5 is turned 180 degrees, so that when the frame assembly is turned over during the welding process, the front and back of the frame assembly can be turned over without releasing the fixing clamping mechanism, thereby avoiding damage to the top welding part of the frame assembly due to improper operation or manual movement when turning over after releasing the fixing of the frame assembly, and also reducing errors caused by frequent clamping. In addition, the process of first rising away from the table top 2 and then turning and descending is adopted to avoid the frame assembly directly passing through the center axis. The rotation is hindered by the table top 2, avoiding the welding inconvenience caused by the height impact of the central axis rotation on the frame assembly welding, wherein the initial position of the frame assembly inner lining plate 5 is always located at the center of the frame assembly, so that after the frame assembly is placed on the surface of the table top 2, it is clamped and fixed by the inner lining plate 5 and then flipped and lowered. The bottom surface after flipping will also be supported by the table top 2, avoiding the bottom of the frame assembly hanging in the air after welding and flipping, and deformation due to force during welding, making it more convenient to flip the front and back sides of the frame assembly for welding, reducing the adverse effects caused by flipping the front and back sides of the frame assembly during welding.

[0039] Reference Figure 1 - Figure 5 As shown, in this embodiment: the wind cleaning mechanism includes:

[0040] The slot plate 21 has two ends fixedly connected to the self-telescopic rod 13, the slot plate 21 is slidably connected to the surface of the raised block 14, the top of the slot plate 21 is fixedly connected to the bracket plate 22, one side of the bracket plate 22 is provided with a tooth groove 23, the top of the mounting plate 3 is fixedly connected to the extension rod 24, the two extension rods 24 are rotatably connected to the cylinder 25 through the shaft, the bottom of the cylinder 25 is fixedly connected to the wind plate 6, both sides of the cylinder 25 are rotatably connected to the connecting rod 26 through the extension plate, the front end of the extension rod 24 is rotatably connected to the third gear 27, and the other end of the connecting rod 26 is connected to the first gear 27. The surfaces of the three gears 27 are connected by rotating shafts, and the surface of the third gear 27 is meshed with the tooth groove 23. When the sleeve 12 moves up or down in a straight line following the raised column 11, the self-telescopic rod 13 will follow the sleeve 12 and move up or down along the surface of the first slide bar 16. The self-telescopic rod 13 is divided into two sections and can be retracted by itself. When the sleeve 12 moves left and right, the self-telescopic rod 13 itself will adjust the distance between itself and the sleeve 12, and the slot plate 21 is fixed to one end of the self-telescopic rod 13, which makes only the self-telescopic rod 13 fixed with the sleeve 12 move along the other end. The self-telescopic rod 13 slides to adjust the spacing, which makes the self-telescopic rod 13 drive the slot plate 21 and the bracket plate 22 to move synchronously when the sleeve 12 rises or falls. The tooth groove 23 is engaged with the third gear 27, so that the bracket plate 22 will drive the third gear 27 to rotate when it moves up and down. The rotation of the third gear 27 drives the connecting rod 26 to move repeatedly, so that the connecting rod 26 can pull the cylinder 25 to drive the wind plate 6 to deflect repeatedly, which is beneficial to the plane of the wind plate 6 to generate wind force when it deflects, blowing downward the dirt and impurities generated during welding on the surface of the frame assembly. At the same time, the frame As the assembly gradually moves upward and approaches the wind plate 6, the frame assembly will flip over. At this time, the frame assembly is closest to the wind outlet of the wind plate 6, and the frame assembly will also be in a vertical state after deflection. During this process, the dust on the surface of the frame assembly is more easily affected by the wind force and its own inclination angle and falls off, thereby making the surface of the frame assembly after welding cleaner, avoiding the influence of dust on the welding surface on the other side after the frame assembly is turned over for welding, and reducing the deviation and quality influence of welding residue on the welding gap of the frame assembly, thereby significantly improving the welding quality of the welding surface after flipping.

[0041] Reference Figure 1 、 Figure 5 and Figure 6 As shown, in this embodiment: the mobile detection mechanism includes:

[0042] The long rod 28 and one side of the base 1 are fixedly connected to two high and low plates 29, and the two high and low plates 29 are of different heights. The two ends of the long rod 28 are fixedly connected to the top of the two high and low plates 29. The surface of the long rod 28 is slidably connected with a slider 30. The bottom of the slider 30 is fixedly connected to the detection device 7. The top of the slider 30 is fixedly connected to a rope chain 31. The top of the rope chain 31 is fixedly connected to the bracket plate 22. A pulley 32 is installed on the top of the high and low plates 29. When the bracket plate 22 is driven upward by the sleeve 12, the bracket plate 22 will pull the rope chain 31 to move upward with the pulley 32 as the turning point, which makes the rope chain 31 move upward. Pull the slider 30 and the detection device 7 upward on the surface of the long rod 28, and the inner lining plate 5 will also rise synchronously at this time. When the detection device 7 and the slider 30 slide obliquely along the long rod 28, not only the height of the detection device 7 rises synchronously with the inner lining plate 5, but also the detection device 7 moves horizontally and scans along the top of the inner lining plate 5, so that the detection device 7 scans the entire top surface of the welded frame assembly horizontally. The detection device 7 scans and analyzes the welded joints of the welded frame assembly through the detection device 7 to ensure that the defects of the weld can be detected after the frame assembly completes single-side welding. The device 7 can detect defects in time, and the top of the frame assembly in the inner lining plate 5 can be fully inspected by the lateral movement of the detection device 7. Once a welding defect is found, the detection device 7 will immediately send a signal to the controller 33, and the controller 33 will immediately start the alarm mechanism to remind the operator to pay attention. At the same time, the detection device 7 can also accurately record the defect position, providing accurate guidance for subsequent repair work. This design not only greatly improves the detection efficiency, but also ensures the welding quality of the frame assembly, effectively avoiding quality problems caused by welding defects. In addition, the lateral scanning process of the detection device 7 is smooth and continuous, and will not damage the vehicle. In addition, after the frame assembly is spliced ​​and fixed, the device first performs a comprehensive scan of the spliced ​​frame assembly through the transverse movement of the detection device 7 to avoid the model error of the spliced ​​frame assembly, so that the wrongly spliced ​​frame assembly components can be discovered in time before welding, effectively preventing welding errors caused by component model mismatch, further improving production efficiency and product quality, and allowing operators to complete the welding and detection of the frame assembly more easily and efficiently during use, providing strong technical support for the production of the frame assembly.

[0043] Reference Figure 1 and Figure 6As shown, in this embodiment: a controller 33 is installed on the surface of the mounting plate 3, and a plurality of hydraulic rods 34 are installed inside the inner lining plate 5. The output end of the hydraulic rod 34 is fixedly connected to the clamping plate 35. The operation state of the entire device is controlled by the controller 33 as the control terminal. When the frame assembly is placed inside the inner lining plate 5, the plurality of hydraulic rods 34 are started to operate, so that the hydraulic rods 34 extend and push the clamping plate 35 to clamp and fix the frame assembly on all sides, firmly restricting the frame assembly inside the inner lining plate 5, and making the welds of the frame assembly accurately butted, avoiding erroneous displacement during welding, so as to It achieves the clamping and limiting effect on frame assemblies of different models. At the same time, the material of the splint 35 has good elasticity and wear resistance, and can adapt to frame assemblies of different sizes and shapes, ensuring that the clamping process is both stable and does not cause damage to the surface of the frame assembly. After the clamping is completed, the controller 33 will receive feedback signals from all hydraulic rods 34 and splints 35 to confirm that the frame assembly has been correctly fixed, and then start the subsequent scanning and welding procedures. The design of this series of actions fully considers the convenience and accuracy of operation, greatly improving the automation level and production efficiency of frame assembly welding.

[0044] Reference Figure 2 and Figure 4 As shown, in this embodiment: there are two slides 19, both of which are installed on the same side of the two circular frames 4. The slides 19 deflect 180 degrees when moving along the top of the U-shaped rod 18. Since the inner lining plate 5 of the device flips in a one-way direction of 180 degrees, it needs to be deflected 180 degrees in the opposite direction when it is reset to the initial position. This makes the two slides 19 always on one side of the circular frame 4, and the sliding and U-shaped rod 18 surface form a strong support for the circular frame 4 and the inner lining plate 5. During the deflection process, through the precise mechanical structure design, it is ensured that the slides 19 can move smoothly and accurately along the top of the U-shaped rod 18 without jamming or offset. In addition, the contact surface between the slide 19 and the U-shaped rod 18 is made of wear-resistant material, which effectively extends the service life and reduces the noise caused by friction. This design not only enhances the stability and reliability of the device, but also improves the safety during operation, ensuring that the staff will not be injured due to device failure during the welding process. At the same time, the precise positioning and strong support of the slide 19 provide a strong guarantee for the precise docking of the frame assembly during the welding process, further improving the welding quality and efficiency.

[0045] Reference Figure 1 and Figure 6As shown, in this embodiment: the long rod 28 is installed at an angle, the slider 30 and the detection device 7 have a certain gravity, and there is a certain distance between the initial position of the detection device 7 and the high and low plates 29. The long rod 28 is installed at an angle, not only can the detection device 7 be lifted and moved laterally through the long rod 28, but also when the bracket plate 22 is lowered, the gravity of the detection device 7 and the slider 30 can pull the rope chain 31 downward, so that the slider 30 slides to the bottom along the surface of the long rod 28. At this time, there is still a certain distance between the slider 30 and the high and low plates 29. distance, thereby avoiding the collision between the detection device 7 and the slider 30 and the high and low plates 29 when they descend, which may cause the detection device 7 to be damaged by the impact force, and prepare for the next welding operation. At the same time, this design also cleverly utilizes the effect of gravity, and the slider 30 can be automatically lowered and reset without an additional power source, which greatly reduces energy consumption and cost. In addition, the inclination angle of the long rod 28 is precisely calculated to ensure the stability and smoothness of the detection device 7 and the slider 30 during movement, and avoid the jamming or shaking caused by improper angles.

[0046] Reference Figure 1 、 Figure 2 and Figure 5 As shown, in this embodiment: the deflection amplitude of the wind plate 6 is about 90° to 120°, and high-intensity wind force is generated by the large-scale repeated deflection of the wind plate 6. The high-intensity wind force can effectively blow away the smoke and harmful gases generated during the welding process, provide operators with a fresher working environment, and reduce the occurrence of occupational diseases. At the same time, this wind force can also cool the welding area to a certain extent, prevent weld deformation or material performance degradation caused by high temperature, and ensure welding quality. In addition, the large-scale repeated deflection design of the wind plate 6 not only enhances the wind effect and improves the cleaning effect of the frame assembly, but also increases the flexibility and applicability of the device, so that it can adapt to the welding needs of frame assemblies of different shapes and sizes.
