[0043] The utility model will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0044] Please see Figure 1-4 A vehicle frame welding frame according to an embodiment of the present invention includes: a base 1; a processing frame 2, disposed on the base 1, for providing welding operation space; a placement platform 4, movably disposed at the top of the base 1, for supporting a vehicle frame 5; a first limiting member 6, disposed on the placement platform 4, for initially positioning the vehicle frame 5 and aligning the clamping side of the vehicle frame 5 with the two sides of the processing frame 2; second limiting members 10, paired and movably disposed on both sides of the processing frame 2, for engaging and clamping the corresponding sides of the vehicle frame 5 from below after the vehicle frame 5 is lifted; a first driving device, disposed on the processing frame 2, for driving the second limiting members 10 to move horizontally to engage or separate from the vehicle frame 5; and a lifting device, disposed on the base 1 and connected to the placement platform 4, for driving the placement platform 4 and its loads thereon... The frame 5 is raised and lowered to facilitate the transfer of the frame 5 from the placement platform 4 to the second limiting member 10; the tilting drive device is connected to the second limiting member 10 and is used to drive the clamped and fixed frame 5 to rotate around the horizontal axis; the controller 3 is located on one side of the processing frame 2 and is electrically connected to the first limiting member 6, the second limiting member 10, the first drive device, the lifting device and the tilting drive device; specifically, the controller 3 has a built-in central processing unit and a signal transceiver module, which can receive the signals fed back by the sensors on each component, and send action signals to each drive device according to the preset program or the operator's instructions, so as to realize the automated control of the entire welding frame operation process. At the same time, the controller 3 is equipped with operation buttons and a display screen, which makes it convenient for the operator to set parameters, start and stop the equipment and observe the equipment operation status.

[0045] The first limiting component 6 includes a slide groove 601 opened at the top of the placement platform 4, a first motor 602, a bidirectional lead screw 603, a slider 604, and a first limiting plate 605. The first motor 602 is fixedly installed in the slide groove 601, and its output shaft is connected to the bidirectional lead screw 603. Each of the two threaded sections of the bidirectional lead screw 603 is threaded with a slider 604, and the slider 604 is slidably adapted to the slide groove 601. A first limiting plate 605 is fixedly installed at the top of each slider 604, and the two first limiting plates 605 are arranged opposite to each other. Specifically, the slide groove 601 is opened along the length direction of the placement platform 4, and its two ends are provided with limiting blocks to prevent the slider 604 from sliding out. The two ends of the bidirectional lead screw 603 are rotatably connected to the inner wall of the slide groove 601 through bearings to ensure smooth rotation of the lead screw. The inner side wall of the first limiting plate 605 is provided with a rubber buffer layer to avoid scratching the surface of the frame 5 during the positioning process.

[0046] A first pressure sensor 606 is provided on each of the two opposing first limiting plates 605. Specifically, the first pressure sensor 606 is embedded in the inner rubber buffer layer of the first limiting plate 605, and its sensing surface is flush with the surface of the buffer layer. When the first limiting plate 605 clamps and positions the frame 5, the sensor can detect the clamping pressure in real time. When the pressure reaches the preset threshold, the first pressure sensor 606 transmits the signal to the controller 3, and the controller 3 then controls the first motor 602 to stop running, thereby achieving accurate and stable initial positioning of the frame 5.

[0047] The first driving device includes a first electric telescopic rod 7; at least one first electric telescopic rod 7 is provided on each side of the processing frame 2, and the telescopic end of the first electric telescopic rod 7 faces the inside of the processing frame 2; specifically, mounting seats are fixed on the columns on both sides of the processing frame 2, and the first electric telescopic rod 7 is fixed to the mounting seats by bolts, with its axis aligned with the width direction of the processing frame 2. Each first electric telescopic rod 7 is equipped with an independent control line connected to the controller 3 to ensure that the telescopic rods on both sides can move synchronously, and can also be adjusted individually according to actual needs to adapt to the clamping requirements of different sized frame frames 5.

[0048] The flipping drive device includes a second motor 8 and a connecting plate 9. The second motor 8 is fixedly mounted on the telescopic end of the first electric telescopic rod 7. The connecting plate 9 is fixedly connected to the output shaft of the second motor 8, and the second limiting member 10 is fixedly mounted on the connecting plate 9. Specifically, the second motor 8 is a servo motor with braking function, and its housing is fixedly connected to the telescopic end of the first electric telescopic rod 7 through a flange. The connecting plate 9 is made of high-strength alloy plate, one end of which is connected to the output shaft of the second motor 8 through a key and locked by a nut. The other end has multiple threaded holes for detachable connection with the second limiting member 10, which facilitates later maintenance and replacement.

[0049] At least two second limiting members 10 are provided on each connecting plate 9. Specifically, the two second limiting members 10 are evenly distributed along the length of the connecting plate 9, and their spacing matches the force points on the side of the frame 5 to ensure that the clamping force on the frame 5 is balanced and to prevent the frame 5 from deforming due to uneven force during the flipping process. When it is necessary to weld frame 5 of different specifications, the adaptation can be achieved by replacing the connecting plates 9 with different spacings or adjusting the installation position of the second limiting members 10 on the connecting plate 9.

[0050] The second limiting member 10 includes a limiting frame 1001, a second electric telescopic rod 1002, and a second limiting plate 1004. The limiting frame 1001 is U-shaped with its opening facing upward, used to support and accommodate the side of the frame 5 from below. The second electric telescopic rod 1002 is disposed on one side plate of the limiting frame 1001. The second limiting plate 1004 is slidably disposed within the limiting frame 1001 and connected to the telescopic end of the second electric telescopic rod 1002. The second limiting plate 1004 is connected to the limiting frame 1001. The other side plate of 01 forms a clamping space; specifically, the inner wall of the limiting frame 1001 is provided with a guide groove, and the two sides of the second limiting plate 1004 are provided with guide blocks that are adapted to the guide groove, so as to ensure that the second limiting plate 1004 slides smoothly in the limiting frame 1001. The bottom of the limiting frame 1001 is provided with reinforcing ribs to improve its load-bearing capacity. The side of the second limiting plate 1004 facing the clamping space is provided with anti-slip texture to enhance the friction with the side of the frame 5 and improve the clamping stability.

[0051] A second pressure sensor 1003 is provided between the telescopic end of the second electric telescopic rod 1002 and the second limiting plate 1004. Specifically, when the second electric telescopic rod 1002 pushes the second limiting plate 1004 to clamp the frame 5, the second pressure sensor 1003 collects clamping pressure data in real time and transmits it to the controller 3. The controller 3 compares the pressure data with a preset safe pressure range. When the pressure reaches the preset value, it controls the second electric telescopic rod 1002 to stop telescopicating. If the pressure exceeds the safe range, it issues an alarm signal and controls the telescopic rod to retract in the opposite direction to prevent damage to the frame 5 due to excessive clamping.

[0052] The lifting device is a third electric telescopic rod 11, with its fixed end set on the base 1 and its telescopic end fixedly connected to the bottom of the placement platform 4. Specifically, the third electric telescopic rod 11 is set along the length of the base 1 to ensure that the placement platform 4 runs smoothly during the lifting process. At the same time, the third electric telescopic rod 10 is equipped with a stroke sensor to provide real-time feedback on the lifting position of the placement platform 4 and transmit the signal to the controller 3 to achieve precise positioning.

[0053] The working principle of this utility model patent for a vehicle frame welding frame is as follows: First, the vehicle frame 5 is placed on the placement platform 4. The controller 3 activates the first limiting component 6, and the first motor 602 drives the bidirectional lead screw 603 to rotate, causing the slider 604 to drive the first limiting plate 605 to initially position the vehicle frame 5. When the first pressure sensor 606 detects that the pressure reaches a preset threshold, the first motor 602 stops. Subsequently, the controller 3 controls the third electric telescopic rod 11 to raise the placement platform 4, and at the same time activates the first electric telescopic rod 7 of the first drive device, pushing the second limiting component 10 to move to both sides of the vehicle frame 5, until the limiting frame... After aligning 1001 with the side of the frame 5, the third electric telescopic rod 11 descends, and the frame 5 falls into the limiting frame 1001. The second electric telescopic rod 1002 pushes the second limiting plate 1004 to clamp the frame 5. After the second pressure sensor 1003 detects that the pressure reaches the standard, the second electric telescopic rod 1002 stops. During welding, the second motor 8 can drive the connecting plate 9 to rotate the frame 5. The stroke sensor provides real-time feedback on the position information of the third electric telescopic rod 11 to ensure accurate lifting. Throughout the process, the controller 3 coordinates the operation of each component based on the signals from each sensor. After welding is completed, each component is reset in the reverse order.

[0054] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
