Description

Technical Field

[0001] This invention relates to the field of welding technology, and more specifically, to a plasma arc welding machine for an art display support block. Background Technology

[0002] To protect the supporting metal blocks of the art display, wear-resistant and corrosion-resistant outer layers are wrapped around areas that are frequently worn and corroded. This outer shell is usually made of sheet metal bent into shape, requiring welding of the seams before fitting (interference fit). Existing welding equipment is not convenient for assembling and welding workpieces that require interference fit. Since welding and assembly are separate processes, the workpieces have already cooled down during assembly, making assembly inconvenient. Summary of the Invention

[0003] In order to overcome the above-mentioned defects of the prior art, the embodiments of the present invention provide an art display support block plasma arc welding machine. The technical problem to be solved by the present invention is that the existing welding device is not convenient for assembling and welding workpieces that require interference fit. Since welding and assembly are separate, the workpiece has cooled down during assembly, which is inconvenient for workpiece assembly.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a plasma arc welding machine for art display support blocks, comprising a worktable, an L-shaped groove at the upper end of the worktable, a T-shaped groove at the upper end of the worktable, a first station at the T-shaped connection of the T-shaped groove, a second station at the rear of the first station, a material dropping hole at the front of the first station, a limiting frame fixedly connected to the upper end of the worktable, a fixing through hole on one side of the limiting frame, a first fixing plate fixedly connected to the upper end of the L-shaped groove, a cylinder fixedly connected to one side of the first fixing plate, and a cylinder on one side of the cylinder. An extension telescopic rod is provided, with a main sliding block fixedly connected to one end of the telescopic rod. The main sliding block is connected to an L-shaped slide groove via a sliding buckle. A second inclined movable block is connected to the main sliding block via a sliding buckle, with the inclined surface of the second movable block facing to the right. A fourth spring is fixedly connected between the second movable block and the main sliding block. A second fixed plate is fixedly connected to the upper end of the T-shaped slide groove. A second spring is fixedly connected to one side of the second fixed plate. An impact slider is fixedly connected to one end of the second spring, and the impact slider is connected to the T-shaped slide groove via a sliding buckle. A first inclined movable block is connected to the impact slider via a sliding buckle. A third spring is fixedly connected between the first inclined movable block and the impact slider. An L-shaped connecting rod is fixedly connected to the upper end of the first inclined movable block. A plasma arc welding gun is provided on the main sliding block. A inclined stop block is fixedly connected to the upper end of the worktable.

[0005] In a preferred embodiment, a connecting plate is connected through the limiting frame. A push plate is fixedly connected to the front end of the connecting plate and is slidably snapped to the limiting frame. A first sliding plate is fixedly connected to the rear end of the connecting plate and is slidably snapped to the limiting frame. Two sets 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 hole.

[0006] In a preferred embodiment, a second unloading frame is fixedly connected to the upper end of the limiting frame, and the second unloading frame is located above the T-shaped chute. The second unloading frame contains multiple sets of second workpieces. A first unloading frame is fixedly connected to the upper end of the limiting frame, and the first unloading frame is located directly above the second station. The first unloading frame contains multiple sets of first workpieces.

[0007] In a preferred embodiment, the lower end of the workbench is fixedly connected to multiple sets of support legs.

[0008] The technical effects and advantages of this invention are as follows:

[0009] 1. The cylinder can drive the telescopic rod to extend and retract, thereby causing the main sliding block to move left and right. The main sliding block causes the second inclined movable block to move left and right. When the right-angled surface of the second inclined movable block contacts the right-angled surface of the first inclined movable block (the main sliding block moves to the left), Figures 4-5 (Process), the second inclined movable block can drive the first inclined movable block to move to the left, thereby driving the impact slider to move to the left, until the first inclined movable block contacts the inclined stop block, and then the first inclined movable block moves forward under the action of the inclined plane (the third spring is compressed, Figures 5-6 (Process), the first inclined 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 push plate to move forward through the connecting plate, pushing the first workpiece at the second station to the first station (the combination of the first workpiece and the second workpiece that was originally welded at the first station is pushed to the drop hole by the first workpiece and falls down); when the inclined surface of the second inclined movable block contacts the inclined surface of the first inclined movable block ( Figures 7-8 (Process) Since the elastic coefficient of the fourth spring is much smaller than that of the third spring, the second inclined movable block will compress the fourth spring, while the third spring will not contract; the device can realize the automatic feeding and assembly of the first and second workpieces, automatically weld the gap of the second workpiece, and unload the workpiece after welding and assembly. Welding and fitting are carried out continuously before and after, effectively utilizing the thermal expansion and contraction of the residual heat of the workpiece welding, making it easier to complete the assembly of the first and second workpieces.

[0021] Depend on Figures 1-9This invention provides a plasma arc welding machine for art display support blocks, including a worktable 1. An L-shaped groove 2 and a T-shaped groove 3 are provided on the upper end of the worktable 1. A first station 5 is provided at the T-shaped connection of the T-shaped groove 3. A second station 31 is provided behind the first station 5. A material drop hole 30 is provided on the front side of the first station 5. A limit frame 4 is fixedly connected to the upper end of the worktable 1. A fixed through hole 12 is provided on one side of the limit frame 4. A first fixing plate 19 is fixedly connected to the upper end of the L-shaped groove 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. A main sliding block 8 is fixedly connected to one end of the telescopic rod 7, and the main sliding block 8 is slidably engaged with the L-shaped groove 2. A second inclined movable part is slidably engaged within the main sliding block 8. Block 29, the second inclined movable block 29 with the inclined surface facing right, the second inclined movable block 29 and the main sliding block 8 are fixedly connected by a fourth spring 27, the upper end of the T-shaped slide 3 is fixedly connected by a second fixed plate 24, one side of the second fixed plate 24 is fixedly connected by a second spring 25, one end of the second spring 25 is fixedly connected by an impact slider 9, and the impact slider 9 is slidably connected to the T-shaped slide 3, the impact slider 9 is slidably connected by a first inclined movable block 10 with the inclined surface facing left, the first inclined movable block 10 and the impact slider 9 are fixedly connected by a third spring 26, the upper end of the first inclined movable block 10 is fixedly connected by an L-shaped connecting rod 11, the main sliding block 8 is equipped with a plasma arc welding gun 28, and the upper end of the worktable 1 is fixedly connected by an inclined stop block 23 ( Figure 10 (The inclined surface shown is to the right); 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 inclined movable block 29 to move left and right. When the right-angled surface of the second inclined movable block 29 contacts the right-angled surface of the first inclined movable block 10 (the main sliding block 8 moves to the left), Figures 4-5 (Process), the second inclined movable block 29 can drive the first inclined movable block 10 to move to the left, thereby driving the impact slider 9 to move to the left, until the first inclined movable block 10 contacts the inclined stop block 23, and then the first inclined movable block 10 moves forward under the action of the inclined surface (the third spring 26 is compressed, Figures 5-6 (Process), the first inclined movable block 10 drives the L-shaped connecting rod 11 to move forward and press the first sliding plate 13; when the inclined surface of the second inclined movable block 29 contacts the inclined surface of the first inclined movable block 10 ( Figures 7-8 (In the process), since the elastic coefficient of the fourth spring 27 is much smaller than that of the third spring 26, the second inclined movable block 29 will compress the fourth spring 27, while the third spring 26 will not contract.

[0022] A connecting plate 14 is connected through the limiting frame 4. A push plate 15 is fixedly connected to the front end of the connecting plate 14, and the push plate 15 is slidably snapped 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 snapped to the limiting frame 4. Two sets of first springs 16 are fixedly connected between the first sliding plate 13 and the limiting frame 4. The first springs 16 and the connecting plate 14 are higher than the fixed through hole 12 (to ensure that the main sliding block 8 can penetrate deep into the bottom of 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 push plate 15 forward through the connecting plate 14, pushing 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 that was originally welded at the first station 5 is pushed to the drop hole 30 by the first workpiece 17 and falls down).

[0023] The upper end of the limiting frame 4 is fixedly connected to a second unloading frame 22, and the second unloading frame 22 is located above the T-shaped chute 3. The second unloading frame 22 contains multiple sets of second workpieces 18. The second workpiece 18 is a frame structure formed by bending sheet metal (the subsequent seam needs to be welded). The upper end of the limiting frame 4 is fixedly connected to a first unloading frame 21, and the first unloading frame 21 is located directly above the second station 31. The first unloading frame 21 contains multiple sets of first workpieces 17. Figure 9 The left side of the first workpiece 17 has a higher density, and its center of gravity is located on the left side of the first workpiece 17, so it will not tilt when pushed.

[0024] The lower end of the workbench 1 is fixedly connected to multiple sets of support legs 20.

[0025] In actual work, the initial state is as follows: Figure 4 As shown, with Figure 4 For the reference view, firstly, multiple sets of first workpieces 17 are loaded into the first unloading frame 21, and multiple sets of second workpieces 18 are added into the second unloading frame 22. One set of first workpieces 17 falls onto the second station 31. The second workpieces 18 cannot fall due to the obstruction of the impact slider 9 (in normal operation, a cover plate is installed on the impact slider 9, which is not shown in the figure for easy observation of the internal structure). The cylinder 6 is activated, which drives 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 inclined movable block 29 to move left and right. When the right-angled surface of the second inclined movable block 29 contacts the right-angled surface of the first inclined movable block 10 (the main sliding block 8 moves to the left), Figures 4-5 (Process), the second inclined movable block 29 can drive the first inclined movable block 10 to move to the left, thereby driving the impact slider 9 to move to the left, until the first inclined movable block 10 contacts the inclined stop block 23, and then the first inclined movable block 10 moves forward under the action of the inclined surface (the third spring 26 is compressed, Figures 5-6(Process), the first inclined movable block 10 drives the L-shaped connecting rod 11 to move forward and press the first sliding plate 13; when the inclined surface of the second inclined movable block 29 contacts the inclined surface of the first inclined 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 inclined movable block 29 will compress the fourth spring 27, while the third spring 26 will not contract. The specific process is as follows:

[0026] First, cylinder 6 starts, causing telescopic rod 7 to retract. Figures 4-5 (Process), the right-angled surface of the second inclined movable block 29 contacts the right-angled surface of the first inclined movable block 10. The second inclined movable block 29 can drive the first inclined movable block 10 to move to the left, thereby driving the impact slider 9 to move to the left. When the impact slider 9 leaves directly below the second drop frame 22, a set of second workpieces 18 fall onto the T-shaped chute 3. Then the plasma arc welding gun 28 moves to the joint of the second workpiece 18 and starts welding the joint of the second workpiece 18 (the plasma arc welding gun 28 stops immediately after welding is completed).

[0027] Subsequently, cylinder 6 continues to drive telescopic rod 7 to retract. Figures 5-6 (Process) The first inclined movable block 10 contacts the inclined stop block 23. The first inclined movable block 10 moves forward under the action of the inclined surface. The first inclined 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 forward through the connecting plate 14, pushing 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, which were originally welded at the first station 5, is pushed by the first workpiece 17 to the drop hole 30 and falls down). When the first inclined movable block 10 and the second inclined movable block 29 separate, under the action of the elastic force of the second spring 25, they impact the sliding plate 15. Block 9 will impact the second workpiece 18, causing the second workpiece 18 to engage with the first workpiece 17 on the first station 5 (the first workpiece 17 and the second workpiece 18 are interference fits, and the thermal expansion and contraction generated by the residual heat during welding makes it easier for the second workpiece 18 to engage with the first workpiece 17; the left side of the first workpiece 17 is provided with an assembly chamfer for easy assembly); when the first inclined movable block 10 moves to the right side of the second inclined movable block 29, the first inclined movable block 10 returns to its original position under the elastic force of the third spring 26, and the first sliding plate 13 also returns to its original position under the elastic force of the first spring 16, and a new set of first workpieces 17 falls onto the second station 31.

[0028] Subsequently, cylinder 6 drives telescopic rod 7 to extend. When the inclined surface of the second inclined movable block 29 contacts the inclined surface of the first inclined movable block 10, the second inclined movable block 29 will compress the fourth spring 27 and retract into the main sliding block 8 to avoid contact. Figures 6-7 (process), finally returning to Figure 4The initial state shown; repeating the above operation can complete the automatic feeding and assembly of the first workpiece 17 and the second workpiece 18, and automatically weld the seam of the second workpiece 18.

[0029] 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.
