DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] See also Figure 1 and Figure 2 As shown, a laser welding device for processing water conservancy gates includes four legs 1, the upper ends of the four legs 1 are commonly fixedly connected to a transport component 2, the upper right end of the transport component 2 is fixedly connected to a material discharge component 2 5, the left side of the material discharge component 2 5 is fixedly connected to two symmetrically arranged material discharge components 1 4, the bottom end of the transport component 2 is fixedly connected to a welding component 6, and the rear left side of the transport component 2 is fixedly connected to a control platform 3.

[0034] During the implementation of this device, the operator is first required to adjust the internal parameters of the control platform 3 according to the actual situation, and further the operator is required to add an appropriate amount of welding fixing plates to the inner cavities of the two blanking components 4. At this time, the operator can insert two gate columns that need to be welded from the right side of the device. At this time, the transport component 2 will drive the two gate columns that need to be welded to move intermittently. During the intermittent movement, the components inside the blanking component 4 can make the reinforcement plates attached to the welded columns through the previous cooperation, so that the welding component 6 will be controlled by the control platform 3 to weld the columns. After the welding is completed, the next reinforcement plate will be welded. After all the welding is completed, the two columns will resist the internal structure of the blanking component 2 5, so that another welded part in the inner cavity of the blanking component 2 5 will fall, so that the welding component 6 can weld it. After the welding is completed, the transport component 2 will rotate in the opposite direction to push out the door frame after the welding is completed;

[0035] It should be further explained that the control platform 3 in this solution is a very mature prior art. In this solution, only its control function is used, and its working principle and circuit connection are not elaborated in detail.

[0036] Furthermore, by setting the transport component 2 to move the welded parts in an intermittent manner during the transportation of the welded parts, it cooperates with the unloading component 4, so that the operator can make adjustments according to the actual welding requirements, and the operator can adjust the transportation path of the welded parts under different welding requirements, thereby realizing diversified operation requirements and improving the applicability of the system.

[0037] See also Figure 3 , Figure 8 and Fig. 9As shown, the welding assembly 6 includes a servo motor 61, the upper end of the servo motor 61 is fixedly connected to the middle of the bottom end of the transport assembly 2, the output end of the servo motor 61 is fixedly connected to the pumping assembly 62 through a coupling, the front and rear sides of the inner surface of the pumping assembly 62 are slidably connected to sliding members 64, the outer surfaces of the two sliding members 64 are slidably connected to two fixing rings 63, the upper ends of the four fixing rings 63 are fixedly connected to the bottom end of the transport assembly 2, the upper ends of the two sliding members 64 are fixedly connected to the laser welding arms 65, the pumping assembly 62 includes a shell four 621, the upper end of the shell four 621 is fixedly connected to the bottom end of the transport assembly 2, the inner surface of the shell four 621 is slidably connected to a sliding plate 622, the output end of the servo motor 61 is fixedly connected to a threaded rod 623 through a coupling, the right end of the threaded rod 623 is rotatably connected to an oil leakage plate 625, the side where the oil leakage plate 625 and the sliding plate 622 are close to each other is commonly fixedly connected to a sealing folding tube 624, and the right end of the shell four 621 is fixedly connected to an oil storage tank 626.

[0038] In the present implementation process, the control platform 3 will control the servo motor 61 to rotate. During the rotation of the servo motor 61, the coupling at the output end will drive the fixedly connected threaded rod 623 to rotate. During the rotation of the threaded rod 623, the sliding plate 622 can be moved to the right by cooperating with the sliding plate 622, thereby pushing the internal hydraulic oil to flow from the gap of the oil leakage plate 625 into the inner cavity of the oil storage tank 626, so that the sliding members 64 are separated from each other. Similarly, during welding, the threaded rod 623 itself can rotate, so that the two sliding members 64 can be brought close to each other, so that the laser welding arm 65 fixedly connected to the upper part of the side where the two sliding members 64 are separated from each other can weld the welded parts.

[0039] Furthermore, by setting two laser welding arms 65 to cooperate with the hydraulic oil in the oil storage tank 626, the two laser welding arms 65 can be brought close to each other as required during welding, and then the gate frame reinforcement sheet is welded under the control of the control platform 3, thereby accurately controlling the entire welding process, reducing human operation errors, reducing welding quality problems caused by human operation errors, and ensuring welding consistency and reliability;

[0040] It should be further explained that the servo motor 61 and the laser welding arm 65 mentioned above are conventional settings in the prior art. In this solution, the servo motor 61 and the laser welding arm 65 are both controlled by the control platform 3, and their working principles and circuit connections are not elaborated in detail here;

[0041] See also Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the blanking component 4 includes a shell 41, a matching component 43 is fixedly connected to the upper end of the shell 41, a pushing component 42 is slidably connected to the inner surface of the shell 41, and the pushing component 42 includes an adjustment plate 421, and two matching rods 422 are slidably connected to the rear of the adjustment plate 421. The middle part of the side of the two matching rods 422 close to each other is jointly rotated and connected with a fixed block 423, and the right sides of the two matching rods 422 are jointly slidably connected with a mounting plate 424, and a blanking plate 425 is fixedly connected to the upper end of the front side of the adjustment plate 421. The matching component 43 includes the shell 421, and the rear part of the adjustment plate 421 is slidably connected to the two matching rods 422. 31, the bottom end of the second shell 431 is fixedly connected to the upper end of the first shell 41, a pull rod 432 is slidably connected to the left side of the inner cavity of the second shell 431, a push plate 434 is fixedly connected to the right end of the pull rod 432, a spring 1 433 is fixedly connected to the left side of the push plate 434, the other end of the spring 1 433 is fixedly connected to the left wall of the inner cavity of the second shell 431, a plurality of reinforcing plates 435 are slidably connected to the right side of the push plate 434, an electromagnet is provided at the front end of the mounting plate 424, the front end of the adjusting plate 421 is inclined, and the side of the blanking plate 425 close to the reinforcing plate 435 is inclined.

[0042] During the implementation of this solution, the operator first needs to add an appropriate amount of reinforcing plates 435 to the inner cavity of the second shell 431. When adding, the operator first needs to pull the pull rod 432 that is slidably connected on the left side, and then the pull rod 432 will drive the push plate 434 to move to the left during the sliding process, thereby squeezing the spring 1 433. After the operator has added an appropriate amount of reinforcing plates 435, the pull rod 432 can be released. Furthermore, the spring 1 433 will drive several reinforcing plates 435 to move to the right through its own rebound. At the same time, after the front end of the adjustment plate 421 is welded, when it touches the reinforcing plate 435, it will move backward due to the inclined setting of the front end. While the adjustment plate 421 moves backward, the blanking plate 425 fixedly connected at the upper end will isolate the reinforcing plate 435 of the inner cavity of the second shell 431. While isolating, several The gap between the reinforcing plates 435 increases, and the reinforcing plate 435 on the right side can be pushed to fall to the upper part of the mounting plate 424, so that the mounting plate 424 can push the reinforcing plate 435 to be close to the welding column. Further, when the adjustment plate 421 is retracted, the middle part of the matching rod 422 is rotatably connected with the fixing block 423, so that the mounting plate 424 at the other end can be pushed forward. During the advancement process, the control platform 3 will control the electromagnet set at the front end of the mounting plate 424, and then adsorb the reinforcing plate 435, so that the reinforcing plate 435 can be close to the surface of the welding column. After further welding is completed, the control platform 3 will release the control of the electromagnet set at the front part of the mounting plate 424, so that the transport component 2 drives the welded part to move, and then the adjustment plate 421 is retracted, so as to weld the next reinforcing plate 435.

[0043] It should be further explained that an electric rotating rod is provided at the rotation connection between the fixing block 423 and the matching rod 422, so that the adjustment plate 421 can drive the mounting plate 424 to reset after contacting the reinforcement plate 435;

[0044] Furthermore, the electromagnet and the electric rotating rod mentioned above are conventional settings in the prior art. In this solution, the electromagnet only utilizes the function of adsorbing the reinforcement plate 435, and its working principle is not described in detail. The electric rotating rod only needs to rotate according to the actual situation in this solution. Similarly, its working principle is not described in detail.

[0045] See also Fig.10 As shown, the transport assembly 2 includes a support plate 21, the upper end of the support plate 21 is fixedly connected to two fixed plates 23, the sides of the two fixed plates 23 close to each other are rotatably connected to two rotating rods 24, the front and rear sides of the two rotating rods 24 are fixedly connected to rubber wheels, and the two rubber wheels on the same side are closely attached to the gate column 22, a double-axis motor 26 is fixedly connected to the middle part of the support plate 21, the front and rear sides of the double-axis motor 26 both penetrate the sides of the two fixed plates 23 close to each other on the same side and extend to the sides of the two fixed plates 23 away from each other, matching grooves 27 are provided on the front and rear sides of the upper end of the support plate 21, a number of auxiliary wheels are rotatably connected to the inner surfaces of the two matching grooves 27, the ends of the two fixed plates 23 close to each other are rotatably connected to two matching wheels 28, the two rotating rods 24 and the front and rear sides of the double-axis motor 26 and the outer surfaces of the two matching wheels 28 on the same side are commonly wound with a transmission belt 25, and the left sides of the two fixed plates 23 are commonly fixedly connected to a matching plate 29.

[0046] During the specific implementation of this solution, when the operator uses it for the first time, he first needs to insert the two gate columns 22 flush from the left side of the device, and then the dual-axis motor 26 controlled by the control platform 3 will be started, and the two gate columns 22 will be adjusted to be aligned through the control of the control platform 3. Further, when it is necessary to weld the reinforcement plate 435 to the outer surface of the gate column 22, the dual-axis motor 26 will drive the transmission belt 25 to rotate through the output ends at the front and rear ends. During the rotation of the transmission belt 25, it will drive the rotating rods 24 wound around the left and right sides to rotate. During the rotation of the two rotating rods 24, the rubber wheels fixedly connected at the front and rear ends are abutted against the inner surface of the gate column 22, so that the gate column 22 can be moved forward and backward during welding, which is convenient for the operator to adjust the front and rear according to the actual situation. Further, when the two gate columns 22 are welded, when they move to the leftmost side of the device, the two springs 258 fixedly connected to the left side of the matching plate 29 will be extended, so that the blanking component 25 can perform secondary blanking, so that the left sides of the two gate columns 22 can be welded at the same time to form a door frame.

[0047] Furthermore, the dual-axis motor 26 mentioned above is a very mature technical means in the prior art. In this solution, only its function of outputting left and right rotation is utilized, and its working principle and circuit connection are not elaborated in detail.

[0048] See also Fig.11 As shown, the unloading component 2 5 includes two connecting blocks 51, the upper ends of the two connecting blocks 51 are commonly fixedly connected to the outer shell 3 52, the middle part of the outer shell 3 52 is slidably connected to a partition 53, the left side of the partition 53 is rotatably connected to two rotating rods 2 54, the middle parts of the two rotating rods 2 54 are commonly rotatably connected to a fixed plate 2 55, the bottoms of the two rotating rods 2 54 are slidably connected to a discharge rod 56, the left end of the discharge rod 56 is fixedly connected to a matching plate 2 57, the left side of the matching plate 2 57 is fixedly connected to two springs 2 58, the two springs 2 58 are symmetrically arranged, and the right ends of the two springs 2 58 are fixedly connected to the left end of the matching plate 1 29.

[0049] In the present implementation process, when the two gate columns 22 move to the leftmost side of the device, the two springs 2 58 will extend, thereby causing the matching plate 2 57 to move to the left, and in the process of the matching plate 2 57 moving to the left, the two discharge rods 56 will be driven to move to the left, and in the process of the two discharge rods 56 moving, the limit of the welding part 2 in the inner cavity of the shell 3 52 will be released, so that the welding part 2 will fall to the upper end of the support plate 21. At this time, the operator only needs to use his hands to assist the welding of the welding part 2. Further, when the two discharge rods 56 move During the movement, due to the sliding connection with the fixed plate 2 55, the partition 53 can be moved to the right, thereby limiting the welding component 2 inside the shell 3 52, so that the welding component 2 in the middle of the side where the bottom of the partition 53 and the two discharge rods 56 are close to each other can fall off, and at the same time, the remaining welding components 2 on the inner surface of the shell 3 52 can be prevented from being pressed on the upper part of the fallen welding component 2. After further welding is completed, the dual-axis motor 26 will rotate in the opposite direction, thereby driving the welded door frame to leave the device, and the operator can then transport it to the next step.
