Description

Technical Field

[0001] This invention relates to the field of chassis flipping and welding technology, and in particular to a high-stability welding device for automobile chassis. Background Technology

[0002] After the chassis components are flipped over, the welding equipment can weld the front and back sides in layers to improve the uniformity of weld quality. Moreover, after flipping, operators do not need to bend over or look up to perform difficult welding, thus reducing labor intensity.

[0003] Patent CN221065043U relates to a motorcycle frame flipping and welding device, including a support base plate, a flipping assembly, and a clamping assembly. A side plate is fixedly installed on the top of the support base plate. This motorcycle frame flipping and welding device, through the coordinated use of a drive motor, a rotating rod, a rotating shaft, a pulley, and a lifting platform, can flip the motorcycle frame during the welding process. This eliminates the need for manual disassembly and reassembly of the motorcycle frame, reducing worker workload and saving time, thus improving welding efficiency. Furthermore, the lifting platform and electric push rod allow for raising and lowering of the motorcycle frame, reducing the need for workers to lift it during clamping, lowering their workload, and avoiding difficulties in adjusting the motorcycle frame while clamping.

[0004] In the aforementioned patent, flipping the motorcycle frame reduces the workload of workers, saves time, and improves welding efficiency. However, it is difficult to prevent accidental contact with the limit frame, which could cause the flipping frame to shake and misalign the welding equipment with the weld line. Furthermore, if the chassis component becomes loose and slips during the flipping process, the flipping frame will impact the slipping chassis component due to inertia. Failure to flip the chassis component too quickly can increase the possibility of inertial displacement or falling. In addition, manual handling and loading are not only extremely labor-intensive and time-consuming, but also difficult to adapt to the pace of mass production. Therefore, it is necessary to design a high-stability welding device for automotive chassis to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-stability welding device for automobile chassis.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A high-stability welding device for automotive chassis includes a welding table and welding equipment, and a tilting assembly. The welding equipment is located on the left side of the welding table. A welding frame is fixedly installed on the front and rear walls of the welding table. A square hole is opened on the top of the welding table, and a tilting frame is rotatably installed on the inner wall of the square hole. A clamp is provided on the top of the tilting frame. The tilting assembly includes a detection hole, an elastic telescopic rod, a limiting frame, an elastic telescopic frame, a limiting plate, a limiting groove, a detection frame, and a stop ring. The detection hole is opened on the top of the tilting frame. The elastic telescopic rod is fixedly installed on the inner wall of the welding table. The limiting frame is fixedly installed on the free end of the elastic telescopic rod. The elastic telescopic frame is fixedly installed on the inner wall of the welding table. The limiting plate is slidably installed on the top of the welding table. The limiting groove is opened on the left side of the limiting plate. The detection frame is slidably installed on the inner wall of the detection hole. The stop ring is fixedly installed on the inner wall of the square hole. The detection frame moves towards the stop ring and contacts the stop ring. The stop ring contacts the detection frame, thereby limiting the detection frame and the tilting frame and pausing the tilting process.

[0007] As a preferred technical solution of the present invention, a flipping roller is rotatably installed on the right side of the flipping frame. The flipping roller can reduce the friction when the flipping frame contacts the elastic telescopic frame. The limiting frame contacts the flipping roller. The bottom left side of the limiting frame is set as an inclined surface. The limiting plate moves backward so that the limiting groove aligns with the limiting frame.

[0008] As a preferred embodiment of the present invention, the probe frame is in contact with the stop ring, and a spring is provided between the probe frame and the flipping frame to support the probe frame. The right side of the elastic telescopic frame is set as an inclined surface.

[0009] As a preferred embodiment of the present invention, the stop ring is used to limit the rotation of the flipping frame, the limiting frame is used to support the flipping frame and improve the stability of welding, the flipping frame passes through the front side of the welding table, and a second spring is provided between the limiting plate and the welding table, which can support the limiting plate.

[0010] As a preferred embodiment of the present invention, it further includes a speed limiting component and a feeding component. The speed limiting component is used to limit the rotational speed of the tilting frame, and the feeding component is used to reduce the feeding intensity. The speed limiting component includes a speed limiting frame, a speed limiting frame, a speed limiting plate, a one-way plate, a one-way rod, a rubber block, and a telescopic spring rod. The speed limiting plate slowly moves to the right, causing the speed limiting frame and the tilting frame to rotate slowly. The slow rotation of the tilting frame drives the chassis assembly to tilt slowly. The speed limiting frame is fixedly installed on the circumferential surface of the tilting frame. The speed limiting frame is fixedly installed on the inner wall of the square hole. The speed limiting plate is slidably installed on the inner wall of the speed limiting frame. The one-way plate is rotatably installed on the inner wall of the speed limiting plate. The one-way rod is fixedly installed on the top of the speed limiting plate. The rubber block is fixedly installed on the top of the inner wall of the speed limiting frame. The telescopic spring rod is disposed inside the speed limiting frame. As a preferred embodiment of the present invention, the left side of the speed limiter is set as an inclined surface. By setting the left side of the speed limiter as an inclined surface, the frictional force when the speed limiter contacts the speed limiter frame can be reduced. The speed limiter frame contacts the speed limiter, the one-way bar contacts the one-way plate, and a torsion spring is provided between the one-way plate and the speed limiter.

[0011] As a preferred embodiment of the present invention, the free end of the telescopic spring rod is fixedly connected to the speed limiter plate, the end of the speed limiter frame away from the flipping frame is set as an arc surface, the speed limiter frame contacts the speed limiter plate, and the one-way plate will not squeeze the rubber block when it moves to the left to reset, so that the one-way plate and the speed limiter plate can be quickly reset.

[0012] As a preferred embodiment of the present invention, the feeding assembly includes a feeding rod, an elastic telescopic block, a rack plate, a gear, a grooved ring, and a square plate. When the chassis assembly passes through the feeding rod, it contacts and squeezes the feeding rod, causing it to rotate. The rotation of the feeding rod pulls the chassis assembly, thereby reducing the intensity of manual feeding. The feeding rod is rotatably mounted on the inner wall of the welding frame. The elastic telescopic block is fixedly mounted on the rear side of the welding table. The rack plate is fixedly mounted on the free end of the elastic telescopic block. The gear is rotatably mounted on the circumferential surface of the feeding rod. The grooved ring is fixedly mounted on the circumferential surface of the feeding rod. The square plate is fixedly mounted on the top of the welding table.

[0013] As a preferred embodiment of the present invention, the rack plate meshes with the gear, the front side of the rack plate is set as an inclined surface, the square plate is elastic, the square plate abuts against the grooved ring, the grooved ring shakes and drives the feeding rod to shake, thereby shaking off the waste material adhering to the circumference of the feeding rod, and at the same time the welding table contacts the rotating feeding rod and scrapes off the waste material on the circumference of the feeding rod.

[0014] The present invention has the following beneficial effects: 1. This invention, by pushing the limiting frame to the right, causes the limiting frame to disengage from the flipping roller and release the limiting effect on the flipping frame. The secondary limiting effect of the limiting plate can prevent accidental collisions that could cause the flipping frame to loosen, thereby ensuring that the chassis assembly is fixed in posture, making the welding torch trajectory and weld seam precisely aligned, and reducing welding size deviation. If the chassis assembly slips during flipping, the stop ring contacts the detection frame, thereby limiting the detection frame and the flipping frame and pausing the flipping process. Timely pausing of the flipping can prevent the slipping chassis assembly from causing secondary impact with the flipping frame, thereby reducing chassis assembly deformation or weld seam cracking, making minor damage to the chassis assembly repairable, reducing direct scrap losses and avoiding complete scrapping of the chassis assembly.

[0015] 2. In this invention, the speed limiter plate moves slowly to the right, causing the speed limiter frame and the tilting frame to rotate slowly. The slow rotation of the tilting frame drives the chassis assembly to tilt slowly. The slow tilting of the chassis assembly can avoid inertial offset caused by excessively fast tilting, ensuring accurate positioning of the chassis assembly and improving the consistency of weld quality.

[0016] 3. In this invention, the one-way plate will not squeeze the rubber block when it moves to the left to reset, so that the one-way plate and the speed limiter can be reset quickly. After the speed limiter is quickly reset, it can accurately return to its initial position. During continuous flipping operation, the speed limiter frame can fit with the inclined surface of the speed limiter in time, avoiding speed control delay or flipping jamming due to reset deviation.

[0017] 4. In this invention, when the chassis assembly passes through the feeding rod, it will contact and squeeze the feeding rod to generate rotation. The rotation of the feeding rod will pull the chassis assembly, thereby reducing the intensity of manual feeding. The feeding rod achieves rotational traction by squeezing the chassis assembly with its own weight, thereby reducing high-intensity operations such as bending over and exerting force. Moreover, the traction process is stable and controllable, further avoiding deviation during manual feeding.

[0018] 5. In this invention, the vibration of the groove ring causes the feeding rod to vibrate, thereby shaking off the waste material adhering to the circumference of the feeding rod. At the same time, the welding table contacts the rotating feeding rod and scrapes off the waste material from the circumference of the feeding rod, preventing excessive waste material from falling onto the chassis welding surface or the tilting frame positioning surface. This can avoid slag inclusions in the weld seams of the chassis components, thereby ensuring the stable quality of the chassis component weld seams. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] Reference Figure 1-7 One embodiment of the present invention is: a high-stability welding device for automobile chassis, comprising a welding table 1 and welding equipment, and further comprising a flipping assembly. The welding equipment is disposed on the left side of the welding table 1. Welding frames 2 are fixedly installed on the front and rear walls of the welding table 1. A square hole 3 is opened on the top of the welding table 1. A flipping frame 4 is rotatably installed on the inner wall of the square hole 3. A clamp 5 is provided on the top of the flipping frame 4. The flipping assembly comprises a detection hole 6, an elastic telescopic rod 7, a limiting frame 8, an elastic telescopic frame 9, a limiting plate 10, a limiting groove 11, a detection frame 12, and a stop ring 13. The detection hole 6 is opened on the top of the flipping frame 4, and the elastic telescopic rod... 7 is fixedly installed on the inner wall of welding table 1, limit frame 8 is fixedly installed on the free end of elastic telescopic rod 7, elastic telescopic frame 9 is fixedly installed on the inner wall of welding table 1, limit plate 10 is slidably installed on the top of welding table 1, limit groove 11 is opened on the left side of limit plate 10, probe frame 12 is slidably installed on the inner wall of probe hole 6, and stop ring 13 is fixedly installed on the inner wall of square hole 3. Timely pausing of the flipping can prevent the sliding chassis component from causing secondary impact with the flipping frame 4, thereby reducing the deformation of chassis component or cracking of weld, making minor damage to chassis component repairable, reducing direct scrap loss and avoiding complete scrapping of chassis component.

[0023] A tilting roller is rotatably installed on the right side of the tilting frame 4. The tilting roller can reduce the friction when the tilting frame 4 contacts the elastic telescopic frame 9. The limiting frame 8 contacts the tilting roller. The bottom left side of the limiting frame 8 is set as an inclined surface. The limiting plate 10 moves backward so that the limiting groove 11 is aligned with the limiting frame 8. The secondary limiting of the limiting plate 10 can prevent accidental collision that causes the tilting frame 4 to loosen, thereby ensuring that the chassis component posture is fixed so that the welding equipment and the weld are accurately aligned and the welding size deviation is reduced.

[0024] The detector frame 12 contacts the stop ring 13. A spring is provided between the detector frame 12 and the flipping frame 4. The spring can support the detector frame 12. The right side of the elastic telescopic frame 9 is set as an inclined surface.

[0025] The stop ring 13 is used to limit the rotation of the flipping frame 4, and the limit frame 8 is used to support the flipping frame 4 to improve the stability of welding. The flipping frame 4 passes through the front side of the welding table 1. A second spring is provided between the limit plate 10 and the welding table 1, and the limit plate 10 can be supported by the second spring.

[0026] During operation: The car chassis assembly to be welded is placed on top of the tilting frame 4. When the chassis assembly is placed on top of the tilting frame 4, it will contact the probe frame 12 and squeeze the probe frame 12. The probe frame 12 moves downward under the pressure of the chassis assembly. The downward movement of the probe frame 12 will pull the spring 1. The spring 1 will deform and store force under the pull of the probe frame 12. At the same time, the downward movement of the probe frame 12 will disengage from the contact with the stop ring 13. After the probe frame 12 disengages from the contact with the stop ring 13, the tilting frame 4 can be rotated. A linear motor is provided on the left side of the clamp 5 and the output end of the linear motor is fixedly connected to the clamp 5. The operation of the linear motor drives the clamp 5 to move to the left side and contact the chassis assembly and fix the chassis assembly. After the chassis assembly is fixed by the clamp 5, the welding equipment will perform welding operations on the chassis assembly. After the top welding of the chassis components is completed, push the limiting plate 10 to move rearward. This movement compresses the second spring, causing it to deform and store force. Simultaneously, the rearward movement of the limiting plate 10 aligns the limiting groove 11 with the limiting frame 8. Once aligned, push the limiting frame 8 to move to the right. This movement disengages the limiting frame 8 from the tilting roller and releases its restriction on the tilting frame 4. After the tilting frame 4 is released from restriction, rotate the tilting frame. 4. The front side drives the clamp 5 and the chassis assembly to rotate clockwise. The clockwise rotation of the flipping frame 4 will drive the flipping roller to rotate. The rotating flipping roller will contact the inclined surface of the elastic telescopic frame 9 and squeeze the elastic telescopic frame 9. The elastic telescopic frame 9 is squeezed and moves to the left and stores force. After the flipping roller continues to rotate and disengages from the contact with the elastic telescopic frame 9, the elastic telescopic frame 9 moves to the right and resets under its own elastic force. The elastic telescopic frame 9 moves to the right and resets to restore the limit on the flipping frame 4, thereby completing the flipping of the chassis assembly. After the chassis assembly is flipped, the welding equipment continues to weld the bottom of the chassis assembly. If the chassis assembly slips during the flipping process, it will cause the chassis assembly to detach from the contact with the detection frame 12. After the chassis assembly detaches from the contact with the detection frame 12, the detection frame 12 moves towards the stop ring 13 under the elastic force of the spring. The detection frame 12 moves towards the stop ring 13 and contacts the stop ring 13. The stop ring 13 contacts the detection frame 12, thereby limiting the detection frame 12 and the flipping frame 4 and pausing the flipping process.

[0027] Reference Figure 1-7 Based on the above embodiments, another embodiment of the present invention further includes a speed limiting component and a feeding component. The speed limiting component is used to limit the rotational speed of the tilting frame 4, and the feeding component is used to reduce the feeding intensity. The speed limiting component includes a speed limiting frame 141, a speed limiting frame 142, a speed limiting plate 143, a one-way plate 144, a one-way rod 145, a rubber block 146, and a telescopic spring rod 147. The speed limiting frame 141 is fixedly installed on the circumferential surface of the tilting frame 4, the speed limiting frame 142 is fixedly installed on the inner wall of the square hole 3, the speed limiting plate 143 is slidably installed on the inner wall of the speed limiting frame 142, the one-way plate 144 is rotatably installed on the inner wall of the speed limiting plate 143, the one-way rod 145 is fixedly installed on the top of the speed limiting plate 143, the rubber block 146 is fixedly installed on the top of the inner wall of the speed limiting frame 142, and the telescopic spring rod 147 is disposed inside the speed limiting frame 142. The slow tilting of the chassis assembly can avoid inertial offset caused by excessively fast tilting, ensuring accurate positioning of the chassis assembly and improving the consistency of weld quality.

[0028] The left side of the speed limiter 143 is set as an inclined surface. By setting the left side of the speed limiter 143 as an inclined surface, the friction between the speed limiter 143 and the speed limiter frame 141 can be reduced. The speed limiter frame 141 contacts the speed limiter 143, the one-way bar 145 contacts the one-way plate 144, and a torsion spring is provided between the one-way plate 144 and the speed limiter 143.

[0029] The free end of the telescopic spring rod 147 is fixedly connected to the speed limiter plate 143. The end of the speed limiter frame 141 away from the flipping frame 4 is set as an arc surface. The speed limiter frame 141 contacts the speed limiter plate 143. When the one-way plate 144 moves to the left to reset, it will not squeeze the rubber block 146, so that the one-way plate 144 and the speed limiter plate 143 can be reset quickly. After the speed limiter plate 143 is quickly reset, it can accurately return to the initial position. During continuous flipping operation, the speed limiter frame 141 can fit with the inclined surface of the speed limiter plate 143 in time, avoiding speed control delay or flipping jamming due to reset deviation.

[0030] The feeding assembly includes a feeding rod 151, an elastic telescopic block 152, a rack plate 153, a gear 154, a grooved ring 155, and a square plate 156. The feeding rod 151 is rotatably mounted on the inner wall of the welding frame 2. The elastic telescopic block 152 is fixedly mounted on the rear side of the welding table 1. The rack plate 153 is fixedly mounted on the free end of the elastic telescopic block 152. The gear 154 is rotatably mounted on the circumferential surface of the feeding rod 151. The grooved ring 155 is fixedly mounted on the circumferential surface of the feeding rod 151. The square plate 156 is fixedly mounted on the top of the welding table 1. The feeding rod 151 achieves rotational traction by squeezing under the weight of the chassis assembly, thereby reducing high-intensity operations such as bending over and exerting force. Moreover, the traction process is stable and controllable, further avoiding deviation during manual feeding.

[0031] The rack plate 153 meshes with the gear 154. The front side of the rack plate 153 is set as an inclined surface. The square plate 156 is elastic. The square plate 156 abuts against the grooved ring 155. The grooved ring 155 vibrates, causing the feeding rod 151 to vibrate, thereby shaking off the waste material adhering to the circumference of the feeding rod 151. At the same time, the welding table 1 contacts the rotating feeding rod 151 and scrapes off the waste material on the circumference of the feeding rod 151, preventing too much waste material from falling onto the chassis welding surface or the positioning surface of the tilting frame 4. This can avoid slag inclusions in the weld of the chassis assembly, thereby ensuring the stable quality of the chassis assembly weld.

[0032] During operation, the clockwise rotation of the tilting frame 4 will cause the speed limiter frame 141 to rotate. The rotation of the speed limiter frame 141 will contact the inclined surface of the speed limiter plate 143 and squeeze the speed limiter plate 143. The speed limiter plate 143 will move to the right due to the squeeze of the speed limiter frame 141. The movement of the speed limiter plate 143 to the right will squeeze the free end of the telescopic spring rod 147. The free end of the telescopic spring rod 147 will retract and store force due to the squeeze of the speed limiter plate 143. At the same time, the movement of the speed limiter plate 143 to the right will drive the one-way plate 144 to move to the right. When the one-way plate 144 moves to the right, it will contact the rubber block 146 and compress the rubber block 146 to produce a slow deformation. The slow deformation of the rubber block 146 causes the one-way plate 144 and the speed limiter plate 143 to move slowly to the right. The slow movement of the speed limiter plate 143 to the right causes the speed limiter frame 141 and the tilting frame 4 to rotate slowly. The slow rotation of the tilting frame 4 drives the chassis assembly to tilt slowly. When the speed limiter frame 141 continues to rotate, it will contact the speed limiter plate 143. After the speed limiter plate 143 is out of contact with the speed limiter frame 141, the speed limiter plate 143 moves to the left to reset under the elastic force of the telescopic spring rod 147. The speed limiter plate 143 moving to the left to reset drives the one-way plate 144 to move to the left to reset. At this time, the one-way plate 144 is not limited by the one-way lever 145 and can rotate to the right. When the one-way plate 144 moves to the left to reset, the rotation generated when the one-way plate 144 contacts the rubber block 146 will not squeeze the rubber block 146. When the one-way plate 144 moves to the left to reset, it will not squeeze the rubber block 146, so that the one-way plate 144 and the speed limiter plate 143 can be quickly reset.

[0033] When the speed limiter 143 moves to the right, it will contact the inclined surface of the rack plate 153 and squeeze the rack plate 153. The rack plate 153 moves backward under the squeeze of the speed limiter 143. The rack plate 153 moves backward and squeezes the gear 154. The gear 154 rotates under the squeeze of the rack plate 153. The rotation of the gear 154 drives the feeding rod 151 to rotate. The rotation of the feeding rod 151 drives the grooved ring 155 to rotate. The rotation of the grooved ring 155 squeezes the square plate 156. The square plate 156 deforms and vibrates under the squeeze of the grooved ring 155. The vibration of the square plate 156 causes the grooved ring 155 to vibrate. The vibration of the groove ring 155 causes the feeding rod 151 to vibrate, thereby shaking off the waste material adhering to the circumference of the feeding rod 151. At the same time, the rotation of the feeding rod 151 will contact the welding table 1. The welding table 1 contacts the rotating feeding rod 151 and scrapes off the waste material on the circumference of the feeding rod 151. When the car chassis component to be welded is placed on top of the tilting frame 4. The chassis assembly is fed through the loading rod 151 from the rear side of the welding station 1. When the chassis assembly passes through the loading rod 151, it will contact the loading rod 151 and squeeze the loading rod 151 to generate rotation. The rotation of the loading rod 151 will pull the chassis assembly, thereby reducing the intensity of manual loading.

[0034] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
