Detailed Description of the Invention

[0023] According to Figures 1-9 , the present invention provides a welding device for a low-density high-strength steel test block, including a bottom plate 1. Four groups of first support legs 2 are fixedly connected to the upper end of the bottom plate 1. A track frame 3 is fixedly connected to the upper ends of the first support legs 2. A feeding mechanism 31 is arranged below the track frame 3. A welding mechanism 30 is arranged in the track frame 3. The welding mechanism 30 includes a pushing block 16, and the pushing block 16 is slidably connected to the track frame 3. Two groups of first rotating seats 20 are fixedly connected to the upper end of the pushing block 16. Two groups of second rotating seats 22 are fixedly connected to the upper end of the track frame 3. One end of each group of second rotating seats 22 is rotatably connected to a second rotating rod 23. A first rotating rod 21 is rotatably connected between each group of second rotating rods 23 and the first rotating seats 20. A welding torch 10 is fixedly connected to one side of each group of second rotating rods 23. A cylinder 15 is fixedly connected to one side of the track frame 3. A telescopic rod 14 extends from one end of the cylinder 15, and the telescopic rod 14 is fixedly connected to the pushing block 16. The cylinder 15 can control the telescopic rod 14 to extend or shorten, driving the pushing block 16 to move left and right. The left and right movement of the pushing block 16 can drive the second rotating rod 23 to rotate around the second rotating seat 22 through the first rotating seat 20 and the first rotating rod 21.

[0024] Two groups of first opening grooves 4 are arranged on the track frame 3. Two groups of second opening grooves 29 are arranged on the pushing block 16, and the first opening grooves 4, the second opening grooves 29, and the first rotating rods 21 are adapted to each other (which can be intuitively reflected by Figure 4 and Figure 6 and Figure 9 ); the first opening grooves 4 and the second opening grooves 29 facilitate the rotation of the first rotating rods 21 and avoid interference.

[0025] The feeding mechanism 31 includes two groups of extending frames 9, and the two groups of extending frames 9 are fixedly connected to the track frame 3. One end of each of the two groups of extending frames 9 is fixedly connected to an end baffle 11. A beveled platform 18 is arranged between the two groups of extending frames 9. Steps are arranged on the beveled platform 18. The side of the beveled platform 18 close to the track frame 3 is a bevel. A fixed connecting rod 25 is fixedly connected to the lower end of the beveled platform 18. A fixing plate 27 is fixedly connected to the lower end of the fixed connecting rod 25. A second spring 26 is fixedly connected to the upper end of the fixing plate 27. An L-shaped sliding plate 12 is fixedly connected to the upper end of the second spring 26, and the fixed connecting rod 25 penetrates through the L-shaped sliding plate 12. A track groove 28 is arranged on the track frame 3, and the L-shaped sliding plate 12 is slidably buckled with the track groove 28. A first spring 13 is fixedly connected to one side of the L-shaped sliding plate 12, and the first spring 13 is fixedly connected to the inner wall of the track frame 3. When the pushing block 16 moves to the right, it will push the L-shaped sliding plate 12 to compress the first spring 13. The L-shaped sliding plate 12 drives the fixed connecting rod 25 to move to the right, and the beveled platform 18 moves downward under the action of its bevel surface ( Figure 5On the right side of the inclined platform 18, there is an inclined surface. As the L-shaped slide plate 12 moves to the right, after the inclined surface of the inclined platform 18 contacts the lower surface of the track frame 3, the inclined platform 18 will move downward, the second spring 26 will be stretched, the inclined platform 18 will disengage from between the two sets of extension frames 9, the inclined platform 18 will continue to move to the right, and will disengage from the two sets of extension frames 9, and the combination of the first workpiece 7 and the second workpiece 8 on the inclined platform 18 will fall out. Figure 5 On the right side of the inclined platform 18, there is an inclined surface. After the inclined surface of the inclined platform 18 contacts the lower surface of the track frame 3, the inclined platform 18 will move downward. As the L-shaped slide plate 12 moves to the right, it will drive the inclined platform 18 to continue moving to the right, and the inclined platform 18 will completely move away from below the extension frame 9. At this time, the combination of the first workpiece 7 and the second workpiece 8 will fall out.

[0026] At the upper end of the inner wall of the track frame 3, two sets of limit strips 24 are fixedly connected. On one side of the pushing block 16, there is a blanking limit groove 19, and the distance between the two sets of limit strips 24 is equal to the width of the blanking limit groove 19. At the upper end of the bottom plate 1, two sets of second support legs 5 are fixedly connected. Between the two sets of second support legs 5, a blanking frame 6 is fixedly connected, and the blanking frame 6 is adapted to the blanking limit groove 19. Inside the blanking frame 6, there are multiple sets of first workpieces 7, and the height of the blanking limit groove 19 and the sum of the depths of the two sets of limit strips 24 are exactly equal to the height of one set of first workpieces 7 (ensuring that each time the pushing block 16 passes below the blanking frame 6, only one set of first workpieces 7 can be pushed). When the blanking limit groove 19 passes directly below the blanking frame 6, one set of first workpieces 7 will fall between the two sets of limit strips 24, and the width of the blanking limit groove 19 is equal to that of the first workpiece 7.

[0027] On each set of extension frames 9, there is an arc-shaped notch groove 17, and the arc-shaped notch groove 17 is located on the movement track of the welding torch 10. On one side of each arc-shaped notch groove 17, there is a cleaning brush 32; when the welding torch 10 passes by the cleaning brush 32, the cleaning brush 32 can clean the muzzle of the welding torch 10; on the upper end of the inclined platform 18, the second workpiece 8 is placed.

[0028] This device is used for welding low-density high-strength steel test blocks, and this device is placed on the workbench ( Figure 8 ).

[0029] During specific operation, first, the manipulator places the second workpiece 8 on the inclined platform 18, and adds multiple sets of first workpieces 7 into the blanking frame 6, so as to Figure 1The state shown is the initial state and the basic view. At this time, the blanking limit groove 19 just moves to directly below the blanking frame 6. A set of first workpieces 7 in the blanking frame 6 fall into the space between two sets of limiting bars 24 through the blanking limit groove 19. The air cylinder 15 controls the telescopic rod 14 to extend, driving the pushing block 16 to move leftward. The pushing block 16 pushes the first workpiece 7 that has fallen between the two sets of limiting bars 24 to move leftward to be combined with the second workpiece 8. The first workpiece 7 and the second workpiece 8 are in interference fit. The pushing block 16 provides pressure to combine the first workpiece 7 and the second workpiece 8. When the pushing block 16 moves leftward, it will also drive the second rotating rod 23 to rotate clockwise around the second rotating seat 22 through the first rotating rod 21. After the combination of the first workpiece 7 and the second workpiece 8 is completed, the air cylinder 15 moves in the reverse direction, and the pushing block 16 moves rightward. During this process, the pushing block 16 will drive the second rotating rod 23 to rotate counterclockwise through the first rotating rod 21. The welding torch 10 can weld the gaps on the front and back sides of the first workpiece 7 and the second workpiece 8 (there are mating relationships between the upper and lower sides of the first workpiece 7 and the second workpiece 8 and other parts, so welding is not performed to prevent the weld seam from affecting the fit). After welding is completed, the welding torch 10 stops immediately. When the welding torch 10 passes through the cleaning brush 32, the cleaning brush 32 can clean the muzzle of the welding torch 10 and remove the welding slag on the muzzle of the welding torch 10. When moving to Figure 1 the state shown, a set of first workpieces 7 fall into the space between two sets of limiting bars 24 through the blanking limit groove 19. At the same time, the pushing block 16 contacts the L-shaped sliding plate 12. If the pushing block 16 continues to move rightward, it will push the L-shaped sliding plate 12 to compress the first spring 13. The L-shaped sliding plate 12 drives the fixed connecting rod 25 to move rightward. The inclined surface platform 18 moves downward under the action of its inclined surface, and the second spring 26 is stretched. The inclined surface platform 18 disengages from between the two sets of extension frames 9. The inclined surface platform 18 continues to move rightward and moves away from directly below the two sets of extension frames 9. The combination of the two sets of first workpieces 7 and the second workpiece 8 on the inclined surface platform 18 will fall ([ Figure 5 there is an inclined surface on the right side of the inclined surface platform 18 in . When the inclined surface of the inclined surface platform 18 contacts the lower surface of the track frame 3, it will cause the inclined surface platform 18 to move downward. As the L-shaped sliding plate 12 moves rightward, it will drive the inclined surface platform 18 to continue moving rightward, and the inclined surface platform 18 will completely move away from below the extension frame 9. At this time, the combination of the first workpiece 7 and the second workpiece 8 will fall. ) (If the combination of the first workpiece 7 and the second workpiece 8 does not fall from directly below the two sets of extension frames 9, it means that the welding deformation amount does not meet the welding quality requirements, and the welded product is a defective product, thus realizing the function of welding deformation inspection). Subsequently, the air cylinder 15 starts in the forward direction, controls the telescopic rod 14 to extend, and returns to Figure 1 the initial state shown. The inclined surface platform 18 returns between the two sets of extension frames 9 again, and the manipulator places a new second workpiece 8 on the inclined surface platform 18.

[0030] Finally, the above are only the preferred embodiments of the present invention and are not intended 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.
