Description
Technical Field
[0001] This invention relates to the field of welding technology, and more specifically, to a plasma arc welding apparatus for building baffles. Background Technology
[0002] In the manufacturing of metal components for building retaining walls, welding is one of the key processes. Currently, for welding metal blocks of building retaining walls in complex spatial locations or with precision assembly, an automated solution combining multi-axis robotic arms and vision imaging systems is commonly used. This solution uses an imaging device for precise positioning before the robotic arm performs the welding operation. While this technology achieves a high degree of automation and welding accuracy, its system structure is complex, involving high-precision robotic arms, vision sensors, and complex calibration and trajectory planning procedures, resulting in high overall equipment costs. Furthermore, the time-consuming initial positioning and path planning processes affect the work cycle and production efficiency. Therefore, the industry urgently needs a new type of metal welding device for building retaining walls that can simplify the system structure, reduce equipment costs, and improve work efficiency while ensuring welding quality.

A second spring 25 is fixedly connected between each set of beveled pins 24 and the plug-in block 23. A second connecting rod 22 is fixedly connected to the upper end of the square block 21, and the second connecting rod 22 is connected to the rail. The slide groove 15 is slidably connected, and four sets of support legs 2 are fixedly connected to the lower end of the base plate 1; the cylinder 8 can control the left and right movement of the sliding block 12 through the extension and retraction of the telescopic rod 11. The sliding block 12 drives the square block 21 to move left and right. When the second connecting rod 22 contacts the displacement inclined plate 10, it will drive the second connecting rod 22 to move back and forth in the track slide groove 15 under the action of the inclined surface (when moving, it will press the limiting clamp 16, the limiting clamp 16 will retract into the sliding block 12, and the main gear 19 will rotate when passing the rack 3).
[0026] The upper end of the base plate 1 is provided with a first track groove 4, and a material drop groove 5 is provided on one side of the first track groove 4. A limiting frame 7 is fixedly connected to the upper end of the base plate 1, and the limiting frame 7 corresponds to the position of the material drop groove 5. A second track groove 6 is provided on the base plate 1, and the connecting frame 13 is slidably connected to the second track groove 6. The limiting frame 7 is used to limit the leftward movement trajectory of the combination of the first workpiece 29 and the second workpiece 33.
[0027] The upper end of the base plate 1 is fixedly connected to a dropping frame 26, and the dropping frame 26 is located directly above the first track groove 4. The dropping frame 26 is provided with a first dropping hole 27, and multiple sets of first workpieces 29 are installed in the first dropping hole 27. The dropping frame 26 is provided with a second dropping hole 28, and multiple sets of second workpieces 33 are installed in the second dropping hole 28.
[0028] The first workpiece 29 has a pin groove 30 on its front side, and the pin groove 30 is adapted to the plug block 23. The first workpiece 29 has four sets of positioning pins 32 on its rear side, and a boss 31 on its rear side.

[0030] by Figure 1 The state is the basic view. During actual operation, multiple sets of first workpieces 29 and second workpieces 33 are firstly placed into the first discharge hole 27 and the second discharge hole 28, respectively. One set of first workpieces 29 and second workpieces 33 then falls onto the first track groove 4. The initial position of the device is as follows: Figure 14 (From a rear view) As shown, cylinder 8 is activated. Cylinder 8 controls the left and right movement of sliding block 12 through the extension and retraction of telescopic rod 11. Sliding block 12 drives square block 21 to move left and right. When the second connecting rod 22 contacts the displacement inclined plate 10, it will be driven by the inclined plane to move back and forth in the track groove 15 (when moving, it will press the limiting clamp 16, which will retract into the sliding block 12. Under the elastic force of the first spring 18, the limiting clamp 16 will protrude outward, which can restrict the movement of the second connecting rod 22 in the track groove 15 without external force, so that it is kept at the front end or the back end of the track groove 15). The entire device is in the following state. Figures 12-13 - Figure 14-Figure 1 - Figure 12 The sequential cyclical motion is as follows; In the device Figure 12 State of motion to Figure 13 In the state, the telescopic rod 11 extends, the sliding block 12 moves to the right, and the main gear 19 will rotate once when it passes the rack 3, driving the plug block 23 to rotate 360 degrees. Then the plug block 23 is inserted into the pin groove 30 of the first workpiece 29 on the first track groove 4 (not fully inserted, the inclined pin 24 retracts into the plug block 23 under the action of the inclined surface). In the device Figure 13 State of motion to Figure 14 In the state, the telescopic rod 11 continues to extend, the sliding block 12 moves to the right, and under the obstruction of the inclined surface of the right displacement plate 10, the second connecting rod 22 moves from front to back. While moving to the right, the plug block 23 pushes the first workpiece 29 backward, so that the first workpiece 29 and the second workpiece 33 are combined. When the plug block 23 is inserted into the end of the pin slot 30, the inclined pin 24 will pop out. In the device Figure 14 State of motion to Figure 1In the state, the telescopic rod 11 retracts, the sliding block 12 moves to the left, and the main gear 19 will rotate once when it passes the rack 3, thereby driving the combination of the first workpiece 29 and the second workpiece 33 to rotate once through the plug block 23 (the limit frame 7 restricts the forward and backward movement of the combination of the first workpiece 29 and the second workpiece 33, and cooperates with the inclined pin 24 to restrict the displacement of the combination of the first workpiece 29 and the second workpiece 33, thereby driving the combination to rotate). At the same time, the plasma arc welder 14 will start during the rotation to weld the joint between the boss 31 and the snap-fit groove 34. In the device Figure 1 State of motion to Figure 12 In the state, the telescopic rod 11 continues to retract, the sliding block 12 moves to the left, and under the obstruction of the inclined surface of the left-side displacement plate 10, the second connecting rod 22 moves from back to front. During this process, the plug block 23 and the inclined pin 24 disengage from the pin groove 30, and the first workpiece 29 and the second workpiece 33 assembly, which have been welded, fall from the material drop chute 5 to complete the unloading.
[0031] In conclusion, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
