[0003] However, traditional devices may not be able to quickly brake the equipment when encountering emergencies such as equipment failure and operational errors, resulting in personal injury and equipment damage. For example, when a welding machine loses control or the weld rotates abnormally, there is no simple and direct way to quickly stop the equipment, leaving operators in a relatively passive state when facing danger. Summary of the invention

[0011] The clamping assembly includes a clamping turntable, a rotation groove is opened in the middle of the upper end of the main body plate, a fixed toothed disc is fixedly connected to the edge of the upper end of the inner wall of the rotation groove, a rotating toothed disc is fixedly connected to the lower end of the clamping turntable, and a second clamping plate is rotatably connected to one side of the lower surface of the clamping turntable;

[0012] Through the above technical scheme, when an accident occurs in the device, the user hides behind the baffle and pulls the corresponding out-of-control pull ring. If the pull ring corresponding to the connecting plate is pulled, since the first card plate is rotatably connected with the connecting plate, the pull ring will drive the first card plate to rotate, and its outer wall will be stuck with the second threaded rod and the groove corresponding to the inner wall of the connecting plate. Similarly, if the pull ring corresponding to the movable plate is pulled, the first card plate will rotate accordingly, and its outer wall will be stuck with the first threaded rod and the groove corresponding to the movable plate. If the pull ring corresponding to the main plate is pulled, since the second card plate is rotatably connected with the clamping turntable, the pull ring will drive the second card plate to rotate, and the outer wall of the second card plate will be stuck with the groove corresponding to the rotating gear plate and the fixed gear plate. This braking method is simple and direct, with high reliability, and can quickly stop the equipment at a critical moment.

[0018] Through the above technical solution, the second clamping plate does not affect the movement of various components during normal operation, but can play a braking role in an emergency. The sliding cooperation between the auxiliary sliding rod and the rotating groove ensures the stability of the clamping turntable during rotation, makes the angle adjustment more precise, and prevents shaking or displacement during rotation, thereby ensuring the position of the welded part after angle adjustment, which is beneficial to improving welding quality.

[0020] Through the above technical solution, the protective shell provides good protection for the fourth servo motor, prevents the motor from being damaged by the outside world, extends the service life of the motor, and ensures the reliability of the entire device.

[0021] Preferably, the upper end of the clamping turntable is fixedly connected with a clamping plate all around, the inner wall of the clamping plate at one end away from the center of the clamping turntable is fixedly connected with a third servo motor, the inner wall of the clamping plate is slidably connected with a positioning slide, the output end of the third servo motor is fixedly connected with a third threaded rod, the inner wall of the positioning slide is threadedly connected with the outer wall of the third threaded rod, and the outer wall of the positioning slide at one end away from the third threaded rod is fixedly connected with a clamping block;

[0024] Through the above technical scheme, the emergency brake trigger system composed of the pull ring, connecting rope, connecting ring and fixed ring is simple and effective. In an emergency, the operator can easily pull the pull ring and transmit force through the connecting rope to rotate the clamping plate to achieve braking. The placement plate provides a stable placement position for the pull ring, which is convenient for the operator to quickly find and operate, thereby improving the response speed of emergency braking and ensuring the safety of personnel and equipment.

When the pull ring is not pulled, the spring force ensures the stability of the device and prevents the card plate from accidentally triggering braking due to factors such as vibration. At the same time, after emergency braking, it is also convenient for the card plate to quickly return to its initial state after troubleshooting, thereby reducing the downtime of the equipment.

[0062] The upper end of the clamping turntable 1001 is fixedly connected with a clamping plate 1002 on all sides, and the inner wall of the clamping plate 1002 is fixedly connected to one end away from the center of the clamping turntable 1001 with a third servo motor 1003. The inner wall of the clamping plate 1002 is slidably connected with a positioning slide 1006. The output end of the third servo motor 1003 is fixedly connected with a third threaded rod 1004. The inner wall of the positioning slide 1006 is threadedly connected with the outer wall of the third threaded rod 1004.

The emergency brake trigger system composed of the pull ring 8, the connecting rope 11, the connecting ring 12 and the fixed ring 13 is simple and effective. In an emergency, the operator can easily pull the pull ring 8 and transmit force through the connecting rope 11 to rotate the card plate to achieve braking. The placement plate 7 provides a stable placement position for the pull ring 8, which is convenient for the operator to quickly find and operate, thereby improving the response speed of emergency braking and ensuring the safety of personnel and equipment.

[0063] The lower end of the first clamping plate 14 away from the fixed ring 13 is fixedly connected with a second positioning spring 18, and the lower ends of the two second positioning springs 18 are respectively fixedly connected to the inner walls of the movable plate 201 and the connecting plate 601, and the two ends of one side of the second clamping plate 15 are fixedly connected with the first positioning spring 16, and the side of the first positioning spring 16 away from the second clamping plate 15 is fixedly connected to the outer wall of the fixed gear disk 102.

When the pull ring 8 is not pulled, the spring force ensures the stability of the device to prevent the clamping plate from accidentally triggering braking due to factors such as vibration. At the same time, after emergency braking, it is also convenient for the clamping plate to quickly return to its initial state after troubleshooting, thereby reducing the downtime of the equipment.

[0064] Working principle: The user places the weldment to be welded on the clamping turntable 1001, ensuring that the weldment is placed in a suitable position to facilitate subsequent clamping operations. Then, the external controller is used to start the third servo motor 1003, and the speed and rotation direction of the third servo motor 1003 are adjusted by the controller to make the clamping block 1005 move slowly and steadily until the weldment is firmly clamped. During the clamping process, the weldment can be ensured to be clamped in the correct position and posture by visual observation or with the help of some auxiliary measuring tools. Then, the electric telescopic rod 302 is started by the controller, and the telescopic length of the electric telescopic rod 302 is controlled according to the height of the weldment and the initial position of the welding machine 205, so that the connecting plate 601 drives the entire welding machine 205 to move to a suitable height, so that the welding head of the welding machine 205 is close to the welding part of the weldment. In this process, some height measuring tools or scale marks set on the device can be used to assist in determining the height. After that, the second servo motor 603 and the first servo motor 202 are started by the controller, and according to the coordinate position of the welding point on the weldment, The rotation of the two servo motors is controlled separately so that the welding machine 205 moves precisely to the top of the welding point on the horizontal plane. This process can be achieved through a pre-programmed path or a manually operated controller. At the same time, the displacement sensor set on the device or the coordinate reference system set on the workbench can be used to assist in positioning. After the welding machine 205 reaches the top of the welding point, the welding machine 205 is started to start welding. During the welding process, if the angle of the welded part needs to be adjusted, the fourth servo motor 104 can be started through the controller so that the clamping turntable 1001 drives the welded part to rotate to a suitable angle to ensure the welding quality. During the operation of the device, if an unexpected situation occurs, the operator must quickly hide behind the baffle 4 and pull the corresponding pull ring 8 according to the out-of-control component. For example, if the welding machine 205 loses control during the horizontal movement, it is judged that the movement related to the moving plate 201 or the connecting plate 601 is out of control, and the corresponding pull ring 8 is pulled to make the device emergency brake to avoid danger. After emergency braking, the device must be fully inspected to eliminate the cause of the fault and ensure that the device can operate normally when it is started again.
