Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically a welding machine tracking device. Background Technology

[0002] Currently, most automated welding machines on the market consist of a robotic arm or multi-axis motion components that hold the welding machine in place. The worker manually mounts the parts to be welded onto a fixed fixture. The worker then operates the robotic arm to begin welding, and the machine follows a fixed trajectory and parameters to begin welding. Automated welding offers significant improvements over purely manual welding, greatly enhancing quality, speed, aesthetics, and cost-effectiveness.

[0003] However, several problems exist in the welding process. In existing technologies, during conventional workpiece welding, the welding machine's sensors typically need to scan the weld seam before welding and then track it in real time during the welding process using the pre-scanned data. However, this approach has several significant issues: first, the pre-scanning step increases the complexity of the workflow; second, pre-scanning cannot handle unexpected situations that occur during welding, such as workpiece displacement or deformation; and third, the intense arc light, high temperatures, and fumes generated during welding may interfere with the normal operation of the sensors, affecting measurement accuracy and stability. Therefore, it is necessary to develop a tracking device that can simultaneously scan and weld during the welding process to improve welding efficiency and quality. Utility Model Content

The controller 8 is electrically connected to the ultrasonic sensor 5 and the drive component 4. The controller 8, the ultrasonic sensor 5 and the control method are all prior art.

[0025] The workpiece to be welded is placed on the welding table 2. The controller 8 starts the drive assembly 4 to drive the welding frame 3 to move laterally from right to left. The ultrasonic sensor 5 scans the weld seam first and transmits the corresponding welding trajectory to the controller 8. The controller 8 controls the drive assembly 4 to drive the clamped welding head 6 to perform welding work along the weld seam trajectory. At the same time, an isolation component 7 is set between the welding head 6 and the ultrasonic sensor 5 to shield the strong arc light, high temperature and dust generated during welding, ensuring the normal scanning of the ultrasonic sensor 5. Thus, the ultrasonic sensor 5 scans synchronously during the welding process, avoiding the pre-scanning step and simplifying the operation process. This device can cope with sudden situations during the welding process, such as workpiece displacement or deformation, and adjust the welding trajectory in real time to ensure the stability and consistency of the welding process.

The horizontal block 41 is located behind the welding table 2. A movable groove 42 is opened laterally on the upper side of the horizontal block 41. A threaded rod 43 is inserted into the movable groove 42 and rotates laterally. A connecting rod 31 is vertically fixed on the lower side of the welding frame 3. A limiting slider 32 is provided at the lower end of the connecting rod 31, which extends into the movable groove 42 and is slidably connected to it. The threaded rod 43 passes through the limiting slider 32 and is threadedly connected to it. A servo motor 44 (existing technology) is provided on the upper side of the workbench 1 on the left side corresponding to the horizontal block 41, which can drive the threaded rod 43 to rotate in both directions.

[0027] The servo motor 44 rotates in both forward and reverse directions, thereby driving the threaded rod 43 to rotate, which in turn drives the limit slider 32, which is threadedly connected to it, to move laterally within the movable groove 42.

[0028] Further details can be found here. Figure 1-4 A rodless cylinder 33 is horizontally and longitudinally arranged on the right side of the welding frame 3 corresponding to the welding head 6. The welding head 6 is fixedly arranged on the right side of the piston block of the rodless cylinder 33. Clamping blocks 34 are symmetrically arranged on the right side of the piston block of the rodless cylinder 33. One clamping block 34 is fixedly connected to the piston block, and the other clamping block 34 can slide back and forth on the piston block. A clamping groove matching the welding head 6 is opened on the opposite side of the two clamping blocks 34. A rotating rod 35 is provided on the side wall of one of the clamping blocks 34, which can drive the two clamping blocks 34 to move closer or further away from each other.

[0029] The welding head 6 is moved horizontally and longitudinally by the rodless cylinder 33, and the welding workpiece is moved laterally by the drive component 4. This enables welding work with complex trajectories. At the same time, two clamping blocks 34 are set to facilitate clamping by the welding table 2, and the height of the welding head 6 can be adjusted according to the welding environment.

[0031] By setting spring 74, the support plate 72 always abuts against the workpiece to be welded during the welding process. In conjunction with roller 73, the support plate 72 can slide smoothly on the workpiece to be welded when the welding frame 3 moves laterally.
