[0002] To protect the art display support metal block, a wear-resistant and corrosion-resistant outer layer is wrapped around the parts that are often worn and corroded. This outer shell is usually formed by bending sheet metal. First, the welds need to be welded, and then socketing (interference fit) is carried out; the existing welding devices are not convenient for assembling and welding workpieces that require interference fit. For workpieces that require interference fit assembly, since welding and assembly are separate, the workpieces have cooled down during assembly, which is not convenient for the assembly of the workpieces. Summary of the Invention

[0003] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a plasma arc welding machine for an art display support block. The technical problem to be solved by the present invention is: the existing welding devices are not convenient for assembling and welding workpieces that require interference fit. For workpieces that require interference fit assembly, since welding and assembly are separate, the workpieces have cooled down during assembly, which is not convenient for the assembly of the workpieces.

[0004] To achieve the above object, the present invention provides the following technical solution: A plasma arc welding machine for an art display support block, including a workbench. An L-shaped chute is provided at the upper end of the workbench, and a T-shaped chute is provided at the upper end of the workbench. A first working station is provided at the T-shaped connection of the T-shaped chute. A second working station is provided at the rear side of the first working station. A blanking hole is provided at the front side of the first working station. A limiting frame is fixedly connected to the upper end of the workbench. A fixed through hole is provided on one side of the limiting frame. A first fixing plate is fixedly connected to the upper end of the L-shaped chute. A cylinder is fixedly connected to one side of the first fixing plate. A telescopic rod extends from one side of the cylinder. One end of the telescopic rod is fixedly connected to a main sliding block, and the main sliding block is slidably buckled with the L-shaped chute. A second beveled movable block is slidably buckled in the main sliding block. The bevel of the second beveled movable block faces right. A fourth spring is fixedly connected between the second beveled movable block and the main sliding block. A second fixing plate is fixedly connected to the upper end of the T-shaped chute. A second spring is fixedly connected to one side of the second fixing plate. One end of the second spring is fixedly connected to an impact sliding block, and the impact sliding block is slidably buckled with the T-shaped chute. A first beveled movable block is slidably buckled in the impact sliding block. A third spring is fixedly connected between the first beveled movable block and the impact sliding block. An L-shaped connecting rod is fixedly connected to the upper end of the first beveled movable block. A plasma arc welding gun is provided on the main sliding block. A beveled stop block is fixedly connected to the upper end of the workbench.

[0005] In a preferred embodiment, a connecting plate is connected through the limiting frame. A pushing plate is fixedly connected to the front end of the connecting plate, and the pushing plate is slidably buckled with the limiting frame. A first sliding plate is fixedly connected to the rear end of the connecting plate, and the first sliding plate is slidably buckled with the limiting frame. Two groups of first springs are fixedly connected between the first sliding plate and the limiting frame, and the first springs and the connecting plate are higher than the fixed through holes.

[0006] In a preferred embodiment, a second blanking frame is fixedly connected to the upper end of the limiting frame, and the second blanking frame is located above the T-shaped sliding groove. A plurality of groups of second workpieces are contained in the second blanking frame. A first blanking frame is fixedly connected to the upper end of the limiting frame, and the first blanking frame is located directly above the second working station. A plurality of groups of first workpieces are contained in the first blanking frame.

[0007] In a preferred embodiment, a plurality of support legs are fixedly connected to the lower end of the workbench.

[0008] Technical effects and advantages of the present invention:

[0009] 1. The air cylinder can drive the telescopic rod to expand and contract, thereby driving the main sliding block to move left and right. The main sliding block drives the second beveled movable block to move left and right. When the right-angled surface of the second beveled movable block contacts the right-angled surface of the first beveled movable block (when the main sliding block moves left, Figures 4 - 5 process), the second beveled movable block can drive the first beveled movable block to move left, thereby driving the impact slider to move left. Until the first beveled movable block contacts the beveled stop block, the first beveled movable block moves forward under the action of the bevel (the third spring is compressed, Figures 5 - 6 process). The first beveled movable block drives the L-shaped connecting rod to move forward and press the first sliding plate. When the first sliding plate is pressed, it can drive the pushing plate to move forward through the connecting plate, and push the first workpiece at the second working station to the first working station (the combination of the first workpiece and the second workpiece welded at the original first working station is pushed to the blanking hole by the first workpiece and leaks down); when the bevel of the second beveled movable block contacts the bevel of the first beveled movable block ( Figures 7 - 8 process), due to the elastic coefficient of the fourth spring being much smaller than that of the third spring, the second beveled movable block will compress the fourth spring, and the third spring does not contract; this device can realize the automatic feeding and assembly of the first workpiece and the second workpiece, automatically weld the gaps of the second workpiece, and discharge the welded and assembled workpieces. The welding and socketing are carried out continuously before and after, effectively utilizing the thermal expansion and contraction of the waste heat of the workpiece welding, and more conveniently completing the assembly of the first workpiece and the second workpiece.

Detailed implementation manners

[0021] By Figures 1 - 9, the present invention provides a plasma arc welding machine for an art display support block, including a workbench 1. There is an L-shaped chute 2 at the upper end of the workbench 1, and a T-shaped chute 3 at the upper end of the workbench 1. A first station 5 is provided at the T-shaped connection of the T-shaped chute 3. A second station 31 is provided at the rear side of the first station 5, and a blanking hole 30 is provided at the front side of the first station 5. A limiting frame 4 is fixedly connected to the upper end of the workbench 1. A fixed through hole 12 is provided on one side of the limiting frame 4. A first fixing plate 19 is fixedly connected to the upper end of the L-shaped chute 2. A cylinder 6 is fixedly connected to one side of the first fixing plate 19. A telescopic rod 7 extends from one side of the cylinder 6. One end of the telescopic rod 7 is fixedly connected to a main sliding block 8, and the main sliding block 8 is slidably buckled with the L-shaped chute 2. A second beveled movable block 29 is slidably buckled in the main sliding block 8. The bevel of the second beveled movable block 29 faces right. A fourth spring 27 is fixedly connected between the second beveled movable block 29 and the main sliding block 8. A second fixing plate 24 is fixedly connected to the upper end of the T-shaped chute 3. A second spring 25 is fixedly connected to one side of the second fixing plate 24. One end of the second spring 25 is fixedly connected to an impact sliding block 9, and the impact sliding block 9 is slidably buckled with the T-shaped chute 3. A first beveled movable block 10 is slidably buckled in the impact sliding block 9. The bevel of the first beveled movable block 10 faces left. A third spring 26 is fixedly connected between the first beveled movable block 10 and the impact sliding block 9. An L-shaped connecting rod 11 is fixedly connected to the upper end of the first beveled movable block 10. A plasma arc welding gun 28 is provided on the main sliding block 8. A beveled stop block 23 is fixedly connected to the upper end of the workbench 1 ( Figure 10 as shown, the bevel faces right); the cylinder 6 can drive the telescopic rod 7 to extend and retract, thereby driving the main sliding block 8 to move left and right. The main sliding block 8 drives the second beveled movable block 29 to move left and right. When the right-angle surface of the second beveled movable block 29 contacts the right-angle surface of the first beveled movable block 10 (when the main sliding block 8 moves left, Figures 4 - 5 process), the second beveled movable block 29 can drive the first beveled movable block 10 to move left, thereby driving the impact sliding block 9 to move left. Until the first beveled movable block 10 contacts the beveled stop block 23, the first beveled movable block 10 moves forward under the action of the bevel (the third spring 26 is compressed, Figures 5 - 6 process), and the first beveled movable block 10 drives the L-shaped connecting rod 11 to move forward to press the first sliding plate 13; when the bevel of the second beveled movable block 29 contacts the bevel of the first beveled movable block 10 ( Figures 7 - 8 process), since the elastic coefficient of the fourth spring 27 is much smaller than that of the third spring 26, the second beveled movable block 29 will compress the fourth spring 27, and the third spring 26 will not contract.

[0022] A connecting plate 14 is connected through the limiting frame 4. A pushing plate 15 is fixedly connected to the front end of the connecting plate 14, and the pushing plate 15 is slidably and snap-connected to the limiting frame 4. A first sliding plate 13 is fixedly connected to the rear end of the connecting plate 14, and the first sliding plate 13 is slidably and snap-connected to the limiting frame 4. Two groups of first springs 16 are fixedly connected between the first sliding plate 13 and the limiting frame 4, and the first springs 16 and the connecting plate 14 are higher than the fixed through hole 12 (ensuring that the main sliding block 8 can penetrate below the connecting plate 14 without being blocked under normal conditions); the first sliding plate 13 can be pressed by the L-shaped connecting rod 11. When the first sliding plate 13 is pressed, it can drive the pushing plate 15 to move forward through the connecting plate 14, and push the first workpiece 17 at the second station 31 to the first station 5 (the combination of the first workpiece 17 and the second workpiece 18 welded at the original first station 5 is pushed by the first workpiece 17 to the blanking hole 30 and leaks down).

[0023] A second blanking frame 22 is fixedly connected to the upper end of the limiting frame 4, and the second blanking frame 22 is located above the T-shaped sliding groove 3. Multiple groups of second workpieces 18 are contained in the second blanking frame 22; the second workpiece 18 is a frame structure bent from sheet metal (subsequent seams need to be welded); a first blanking frame 21 is fixedly connected to the upper end of the limiting frame 4, and the first blanking frame 21 is located directly above the second station 31. Multiple groups of first workpieces 17 are contained in the first blanking frame 21 ( Figure 9 the density of the left side of the first workpiece 17 is relatively high, and the center of gravity is located on the left side of the first workpiece 17, and it will not tilt when being pushed).

[0024] Multiple groups of support legs 20 are fixedly connected to the lower end of the workbench 1.

[0025] During specific operation, in the initial state as Figure 4 shown, taking Figure 4 as the reference view, first, multiple groups of first workpieces 17 are loaded into the first blanking frame 21, multiple groups of second workpieces 18 are added to the second blanking frame 22. One group of first workpieces 17 falls onto the second station 31, and the second workpiece 18 cannot fall due to the block of the impact slider 9 (during normal operation, a cover plate will be installed on the impact slider 9. For the convenience of observing the internal structure, it is not drawn in the figure). The air cylinder 6 is started, which can drive the telescopic rod 7 to expand and contract, thereby driving the main sliding block 8 to move left and right. The main sliding block 8 drives the second beveled movable block 29 to move left and right. When the right-angle surface of the second beveled movable block 29 contacts the right-angle surface of the first beveled movable block 10 (when the main sliding block 8 moves left, Figures 4 - 5 process), the second beveled movable block 29 can drive the first beveled movable block 10 to move left, thereby driving the impact slider 9 to move left. Until the first beveled movable block 10 contacts the beveled stop block 23, the first beveled movable block 10 moves forward under the action of the inclined surface (the third spring 26 is compressed, Figures 5 - 6Process), the first beveled movable block 10 drives the L-shaped connecting rod 11 to move forward and press the first sliding plate 13; when the bevel of the second beveled movable block 29 contacts the bevel of the first beveled movable block 10 ( Figures 7 - 8 Process), since the elastic coefficient of the fourth spring 27 is much smaller than that of the third spring 26, the second beveled movable block 29 will compress the fourth spring 27, and the third spring 26 will not contract. The specific process is as follows;

[0026] First, the air cylinder 6 starts and drives the telescopic rod 7 to contract ( Figures 4 - 5 Process), the right-angled surface of the second beveled movable block 29 contacts the right-angled surface of the first beveled movable block 10. The second beveled movable block 29 can drive the first beveled movable block 10 to move leftward, thereby driving the impact slider 9 to move leftward. When the impact slider 9 leaves directly below the second blanking frame 22, a group of second workpieces 18 fall onto the T-shaped chute 3. Subsequently, the plasma arc welding gun 28 moves to the seam of the second workpiece 18, and the plasma arc welding gun 28 starts to weld the seam of the second workpiece 18 (the plasma arc welding gun 28 stops immediately after welding is completed);

[0027] Subsequently, the air cylinder 6 continues to drive the telescopic rod 7 to contract ( Figures 5 - 6 Process), the first beveled movable block 10 contacts the beveled stop block 23. The first beveled movable block 10 moves forward under the action of the bevel. The first beveled movable block 10 pushes the first sliding plate 13 forward through the L-shaped connecting rod 11. The first sliding plate 13 drives the push plate 15 to move forward through the connecting plate 14, and pushes the first workpiece 17 at the second station 31 to the first station 5 (the combined body of the first workpiece 17 and the second workpiece 18 welded at the original first station 5 is pushed by the first workpiece 17 to the blanking hole 30 and leaks down); when the first beveled movable block 10 and the second beveled movable block 29 are separated, under the action of the elastic force of the second spring 25, the impact slider 9 will impact the second workpiece 18, so that the second workpiece 18 is clamped onto the first workpiece 17 at the first station 5 (the first workpiece 17 and the second workpiece 18 are in interference fit. Using the thermal expansion and contraction generated by the heat during welding, it is easier for the second workpiece 18 to be clamped onto the first workpiece 17. An assembly chamfer for easy assembly is provided on the left side of the first workpiece 17); when the first beveled movable block 10 moves to the right side of the second beveled movable block 29, the first beveled movable block 10 returns to its original position under the action of the elastic force of the third spring 26, and the first sliding plate 13 also returns to its original position under the action of the elastic force of the first spring 16. A new group of first workpieces 17 fall onto the second station 31;

[0028] Subsequently, the air cylinder 6 drives the telescopic rod 7 to extend. When the bevel of the second beveled movable block 29 contacts the bevel of the first beveled movable block 10, the second beveled movable block 29 will compress the fourth spring 27 and retract into the main slider 8 for avoidance ( Figures 6 - 7 Process), and finally return to Figure 4The initial state shown; Repeating the above operations can complete the automatic loading and assembly of the first workpiece 17 and the second workpiece 18, and automatically perform seam welding on the second workpiece 18.

[0029] Finally: The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
