[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example

[0023] Please see Figures 1-4 The present invention provides the following technical solution: a welding clamping fixture for an automobile seat frame, comprising a base plate 1, a controller 6 disposed on the left side of the base plate 1, two slot frames 2 fixedly connected to the upper surface of the base plate 1, a sliding column 7 slidably connected inside each slot frame 2, a first electric push rod 8 disposed inside each slot frame 2, the telescopic end of each first electric push rod 8 being fixedly connected to the bottom end of the sliding column 7, a rotating collar 11 disposed above each sliding column 7, a second electric push rod 12 fixedly connected to the inner wall of the inner ring of each rotating collar 11, a clamping plate 13 fixedly connected to the telescopic end of each second electric push rod 12, a serrated ring 18 fixedly connected to the outer surface of the inner ring of each rotating collar 11, a brake motor 15 disposed above each rotating collar 11, a gear 17 fixedly connected to the power output end of each brake motor 15, and each gear 17 meshing with the serrated ring 18;

[0024] In this embodiment, the controller 6 adopts a programmable logic controller (PLC), which is a digital computing and operating electronic system designed specifically for industrial environments. It stores user instructions through a programmable memory and can realize automated control of machinery or production processes during production. Meanwhile, the brake motor 15 is a special motor that can quickly generate braking torque when the power is off, so that the motor shaft stops rotating and remains stationary. The rotating collar 11 adopts an inner and outer ring structure design.

[0025] Specifically, two sets of fixing pins 3 are provided on the top of the base plate 1. The bottom end of each fixing pin 3 passes through the base plate 1 and extends to the bottom of the base plate 1. In this embodiment, by cooperating with the reserved positioning holes of the fixing pins 3 on the production line floor or workbench, the base plate 1 can be firmly locked in the preset position, preventing the tooling from shifting or shaking when subjected to clamping force, welding impact force or equipment vibration, providing a stable foundation support for the entire tooling system, and ensuring that the positioning accuracy of each component is not affected during the welding process.

[0026] Specifically, a mounting plate 5 is fixedly connected to the right side of the controller 6. The right side of the mounting plate 5 is fixedly connected to the left side of the base plate 1. In this embodiment, the controller 6 is stably assembled on the side of the base plate 1 through the rigid connection structure of the mounting plate 5. This ensures that the relative position of the controller 6 and the tooling body is fixed, which facilitates the orderly connection of the circuit with various electric push rods, motors and other actuators. It also allows the operator to conveniently observe the equipment status and adjust the parameters within a safe operating range, while avoiding direct contact of welding spatter with the controller 6 and causing damage.

[0027] Specifically, each slot frame 2 has a reinforcing frame 4 fixedly connected to its outer surface, and the bottom surface of each reinforcing frame 4 is fixedly connected to the upper surface of the base plate 1. In this embodiment, the reinforcing frame 4 forms a stable support structure, which enhances the connection strength between the slot frame 2 and the base plate 1. When the sliding column 7 moves up and down in the slot frame 2 or bears the clamping load, it can effectively disperse the lateral force and torque on the slot frame 2, prevent the slot frame 2 from tilting or deforming due to long-term stress, and extend the service life of the tooling.

[0028] Specifically, each first electric push rod 8 is fixedly connected to a fixing ring 9 at its bottom end. The bottom surface of each fixing ring 9 is fixedly connected to the inner bottom wall of the slot frame 2. In this embodiment, the bottom end of the first electric push rod 8 is firmly fixed inside the slot frame 2 by the fixing ring 9, ensuring that the electric push rod will not move or shake when it drives the sliding column 7 to extend and retract, so that the thrust can be stably transmitted to the sliding column 7, ensuring the smoothness and accuracy of height adjustment, and avoiding adjustment errors or equipment failures caused by loose connections.

[0029] Specifically, a connecting frame 10 is fixedly connected to the outer surface of the outer ring of each rotating collar 11, and the bottom surface of each connecting frame 10 is fixedly connected to the top of the sliding column 7. In this embodiment, the connecting frame 10 realizes the rigid connection between the rotating collar 11 and the sliding column 7, so that the height adjustment movement of the sliding column 7 can be synchronously transmitted to the rotating collar 11 and the clamping structure. At the same time, it provides a stable support foundation for the rotating collar 11, ensuring that the overall structure will not shift when it rotates under the drive of the brake motor 15, thus ensuring the accuracy of angle adjustment.

[0030] Specifically, each connecting frame 10 has a fixed base 16 fixedly connected to its upper surface, and the upper surface of each fixed base 16 is fixedly connected to the bottom surface of the brake motor 15. In this embodiment, the brake motor 15 is stably installed on the connecting frame 10 by the fixed base 16, so that the motor output shaft and the gear 17 and the sawtooth ring 18 maintain a precise meshing position, ensuring efficient and stable power transmission, while avoiding loosening of the connection due to vibration during motor operation, and ensuring the response accuracy and reliability of angle adjustment.

[0031] Specifically, protective pads 14 are fixedly connected to the sides of the two clamping plates 13 that are close to each other. Each protective pad 14 is made of silicone. In this embodiment, the silicone protective pads 14 directly contact the surface of the seat frame. By utilizing the elastic deformation properties of silicone, the friction during clamping can be increased to prevent the frame from slipping during welding. It can also buffer the impact of clamping force on the surface of the frame, avoiding damage such as indentations and scratches caused by rigid contact. At the same time, silicone has the properties of high temperature resistance and wear resistance, which can adapt to the welding operation environment and extend the service life of the protective structure.

[0032] The working principle and usage process of this utility model are as follows: First, the base plate 1 is installed on the production line floor or workbench using the fixing pin 3 to ensure the overall stability of the fixture. Then, the condition of each component must be carefully checked to confirm that the protective pad 14 is undamaged, the connecting frame 10 and the sliding column 7 are securely connected, and the program parameters of the controller 6 are accurate. When it is necessary to clamp or loosen the seat frame, the second electric push rod 12 receives a signal from the controller 6 and drives the clamping plate 13 to move. Simultaneously, the protective pad 14 provides flexible clamping to prevent damage to the frame surface. When the first electric push rod 8 is working, it can push the sliding column 7 up and down along the slot frame 2, thereby adjusting the height of the clamping structure. Meanwhile, when the brake motor 15 is running, it... The meshing transmission between gear 17 and sawtooth ring 18 drives the rotating collar 11 to rotate, thereby achieving angle adjustment. After power failure, the current angle can be stably locked. After completing the preliminary preparation, the operator places the skeleton to be welded between the two clamping plates 13 and starts the second electric push rod 12 through the controller 6 to clamp the skeleton with the clamping plates 13. If the height needs to be adjusted, the controller 6 controls the extension and retraction of the first electric push rod 8 to allow the sliding column 7 to lift the skeleton to the appropriate position. If the angle needs to be adjusted, the brake motor 15 is started. After the skeleton rotates to the required angle, the motor is turned off. The whole process relies on automated control to accurately complete clamping, height and angle adjustment, which significantly improves the convenience and stability of welding operations.

[0033] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
