[0024] Depend on Figures 1-13This invention provides a welding device for asphalt concrete mixing components, including a workbench 4. A V-shaped mounting plate 6 is fixedly connected to the upper end of the workbench 4. A cylinder 28 is fixedly connected to the front side of the V-shaped mounting plate 6. A telescopic rod 22 extends from the rear side of the cylinder 28. A front push plate 23 is fixedly connected to the rear end of the telescopic rod 22. A first mounting groove 24 is provided on the left side of the front push plate 23. A first spring 25 is fixedly connected to one side of the inner wall of the first mounting groove 24. A first sliding rod 12 is fixedly connected to one end of the first spring 25. A first inclined block 13 is fixedly connected to one end of the first sliding rod 12. A first clamping plate 14 is fixedly connected to the rear side of the first inclined block 13. A first mounting rod 15 is fixedly connected to the upper end of the first clamping plate 14. A first welding torch 16 is fixedly connected to the upper end of the first mounting rod 15. A second mounting groove 26 is provided on the right side of the front push plate 23. A second spring 27 is fixedly connected to one side of the inner wall of the second mounting groove 26. One end of 27 is fixedly connected to a second sliding rod 17, one end of the second sliding rod 17 is fixedly connected to a second inclined block 18, the rear side of the second inclined block 18 is fixedly connected to a second clamping plate 19, the upper end of the second clamping plate 19 is fixedly connected to a second mounting rod 20, and the upper end of the second mounting rod 20 is fixedly connected to a second welding torch 21; the cylinder 28 drives the front push plate 23 to extend and retract through the telescopic rod 22. When the telescopic rod 22 retracts, under the action of the inclined surface of the V-shaped mounting plate 6, the first inclined block 13 and the second inclined block 18 will move closer to each other, the first sliding rod 12 and the second sliding rod 17 respectively compress the first spring 25 and the second spring 27 and retract into the first mounting groove 24 and the second mounting groove 26, the first clamping plate 14 and the second clamping plate 19 move closer to each other, and similarly the first mounting rod 15 and the second mounting rod 20 move closer to each other. When the telescopic rod 22 extends, under the action of the inclined surface of the V-shaped mounting plate 6 and the elastic force of the first spring 25 and the second spring 27, the first clamping plate 14 and the second clamping plate 19 move away from each other.
[0025] The upper end of the workbench 4 is provided with a first slide groove 10, and the left and right sides of the first slide groove 10 are provided with second slide grooves 11.
[0026] The upper end of the workbench 4 is fixedly connected to a dropping frame 7. The dropping frame 7 is provided with a first dropping hole 8, which is located directly above the first slide 10. Multiple sets of first workpieces 1 are installed in the first dropping hole 8. Second dropping holes 9 are provided on both the left and right sides of the first dropping hole 8, which are located directly above the second slide 11. Multiple sets of second workpieces 3 are installed in the second dropping holes 9.
[0027] The first workpiece 1 is provided with two sets of transverse welds 2, and the lower end of the workbench 4 is fixedly connected with four sets of support legs 5.
[0028] In actual operation, the initial state of the device is as follows: Figure 9 and Figure 10 As shown, multiple sets of first workpieces 1 are added into the first discharge hole 8, with the bottom set of first workpieces 1 falling onto the first slide groove 10. Multiple sets of second workpieces 3 are added into the two sets of second discharge holes 9, with the bottom set of second workpieces 3 falling onto the second slide groove 11. The cylinder 28 is activated, and the cylinder 28 drives the front push plate 23 to extend and retract via the telescopic rod 22. When the telescopic rod 22 retracts, under the action of the inclined surface of the V-shaped mounting plate 6, the first inclined block 13 and the second inclined block 18 will move closer to each other. The first slide rod 12 and the second slide rod 17 respectively compress the first spring 25 and the second spring 27 and retract into the first mounting groove 24 and the second mounting groove 26. Figure 8 When the first spring 25 and the second spring 27 are in a compressed state, the first clamping plate 14 and the second clamping plate 19 move closer to each other. Similarly, the first mounting rod 15 and the second mounting rod 20 move closer to each other. When the telescopic rod 22 extends, under the action of the inclined surface of the V-shaped mounting plate 6 and in conjunction with the elastic force of the first spring 25 and the second spring 27, the first clamping plate 14 and the second clamping plate 19 move away from each other, and the device proceeds according to... Figures 10-11 - Figures 12-13 - Figure 10 The sequential cyclical motion is as follows;
[0029] When the device is Figure 10 The state shown moves to Figure 11 In the state shown, the telescopic rod 22 retracts, causing the front push plate 23 to move forward, and the first clamping plate 14 and the second clamping plate 19 move obliquely and approach each other. The first clamping plate 14 and the second clamping plate 19 respectively push a set of second workpieces 3 to insert into the first workpiece 1.
[0030] When the device is Figure 11 The state shown moves to Figure 12 In the indicated state, the telescopic rod 22 extends, causing the front push plate 23 to move to the rear. The first clamping plate 14 and the second clamping plate 19 move obliquely and move away from each other. The front push plate 23 pushes back until it just contacts the first workpiece 1. The first clamping plate 14 and the second clamping plate 19 move away from below the two sets of second drop holes 9 respectively, and the new second workpiece 3 falls onto the second slide groove 11.
[0031] When the device is Figure 12 The state shown moves to Figure 13In the indicated state, the telescopic rod 22 continues to extend, causing the front push plate 23 to continue moving backward, pushing the first workpiece 1 to move backward one position. The first clamping plate 14 and the second clamping plate 19 continue to move obliquely and move away from each other, causing the first mounting rod 15 and the second mounting rod 20 to move obliquely and move away from each other, thereby causing the first welding torch 16 and the second welding torch 21 to move in the opposite direction to the first slide groove 10. The welding is started when the first welding torch 16 and the second welding torch 21 pass directly above the transverse weld 2 below them, and the second workpiece 3 and the first workpiece 1 are welded (during this process, the first workpiece 1 is pushed from front to back by the front push plate 23, and the first welding torch 16 and the second welding torch 21 are moved backward in sync with the front push plate 23, that is, the first welding torch 16 and the second welding torch 21 only move to the left and right sides relative to the first workpiece 1 pushed directly below them). The welding stops immediately after completion.
[0032] When the device is Figure 13 The state shown moves to Figure 10 In the state shown, the telescopic rod 22 retracts, causing the front push plate 23 to move forward. During this process, the first workpiece 1 will separate from the front push plate 23. The first clamping plate 14 and the second clamping plate 19 move obliquely and approach each other, causing the first welding gun 16 and the second welding gun 21 to move obliquely and approach each other. The first welding gun 16 and the second welding gun 21 start to weld the weld between the two sets of first workpieces 1.
[0033] Repeat the above operation twenty times as one cycle. Twenty first workpieces 1 are welded together to form one part. In the first four cycles, the first welding torch 16 and the second welding torch 21 are not activated (in these four cycles, the first workpiece 1 has not yet been assembled directly below the first welding torch 16 and the second welding torch 21).
[0034] 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.
