[0016] Compared with the prior art, it has the following beneficial effects:

[0017] 1. In the present invention, the steel plate to be processed is positioned and clamped by a clamping assembly, and at the same time, the welding positions of the two steel plates are calibrated inside a closed frame according to the welding positions of the steel plates to be processed, so as to improve the welding accuracy of the steel plates. After the welding positions of the steel plates to be processed are calibrated by the clamping assembly, the inclination angle of the steel plates to be processed is controlled to make the steel plates to be processed in an inclined state, and the steel plates to be processed are automatically welded by cooperating with the welding assembly arranged on the top of the closed frame. The welding positions of the steel plates to be processed are obtained by an industrial CCD camera arranged above the inside of the closed frame, and the coordinate values ​​of the welding areas are obtained by using analysis software, and the coordinate value parameters are input into the controller of the welding assembly, so as to control the welding assembly to realize automatic welding processing of the steel plates to be processed, thereby solving the problems of low welding efficiency and high labor intensity in the prior art of welding the steel plates to be processed by manual welding after the steel plates to be processed are fixed and limited.

[0018] 2. In the present invention, the cleaning component is used to clean impurities in the welding area of ​​the steel plate to be processed before welding, so as to prevent impurities in the welding area from affecting the welding accuracy. At the same time, the cleaning component is also used to absorb the welding smoke of the steel plate during the welding process, and the cleaning component can also be used to preheat the welding area of ​​the steel plate before welding, thereby greatly improving the subsequent welding processing accuracy of the steel plate.

[0019] 3. When welding steel plates, the position of the welding gun is adjusted according to the position of the welding area. By pre-inputting the working path of the welding gun, the welding gun can complete automatic welding of the steel plate according to the path parameters without manual auxiliary operation. On the one hand, it avoids harm to the health of humans during the steel plate welding process, and on the other hand, it can also improve the welding stability of the steel plate to a certain extent, thereby ensuring the welding accuracy of the steel plate.

[0020] 4. By controlling the movable block at the rear side to move downward, the rotating blocks on both sides of the connecting frame rotate inside the movable blocks on the front and rear sides respectively, so that the connecting frame is tilted inside the closed frame. At this time, the two steel plates to be processed are in a tilted state with the front side higher than the rear side. The welding gun in the welding assembly is used to automatically weld the two steel plates. Since the steel plates are in a tilted state, the welding slag generated during the welding process will fall along the steel plates to the bottom of the closed frame to prevent the welding slag from adhering to the steel plates and then cooling and shaping, which will affect the quality of the welded steel plates. After the steel plates are welded, the leftmost clamp is used to send the welded steel plates through the right material guide port to the conveyor frame on the right. The conveyor frame is used to automatically discharge the steel plates after welding, without the need for manual auxiliary unloading, thereby realizing automatic continuous welding of the steel plates, and greatly improving the welding efficiency of the steel plates.

[0021] 5. Before the welding process of the steel plate is carried out, the present invention uses a cleaning brush to clean the impurities on the surface of the steel plate. At this time, the cleaning liquid is sent into the interior of the air guide port through the material guide interface and the material guide tube. After the impurities on the surface of the steel plate are cleaned, hot air is introduced into the interior of the air guide port through the material guide interface and the material guide tube to preheat the welding area on the surface of the steel plate. Finally, when the steel plate is welded with a welding gun, the cleaning frame is controlled to be on one side of the welding gun, and the smoke generated during the welding process is extracted by using the material guide interface and the material guide tube. This can not only greatly improve the surface welding accuracy of the steel plate, but also improve the environmental protection of the welding processing combination machine tool, and reduce the pollution of the welding process to the environment around the machine tool.

[0032] See also Figures 1 to 7 As shown, a steel plate processing combined machine tool capable of realizing automatic welding comprises a closed frame 1 and a conveying frame 2. The conveying frames 2 are fixedly arranged on the left and right sides of the closed frame 1, and the left and right sides of the closed frame 1 are also provided with material guide openings 3. The material guide openings 3 on the left and right sides realize automatic feeding and unloading operations inside the closed frame 1, which solves the problem that the steel plate needs to be manually loaded and unloaded during the processing, which increases the labor intensity and reduces the efficiency of steel plate processing;

[0033] The bottom of the inner wall of the two material guide ports 3 is rotatably provided with a material guide roller 4, and the upper part of the inside of the two material guide ports 3 is provided with a closed baffle 5 which slides up and down through an electric push rod. After the steel plate to be processed is fed into the interior of the closed frame 1, the closed baffle 5 inside the two material guide ports 3 is controlled to move downward, and the two closed baffles 5 are used to control the closing of the material guide ports 3 on the left and right sides of the closed frame 1, so as to prevent the smoke generated during the welding process of the steel plate from escaping from the interior of the closed frame 1, thereby improving the environmental protection of the processing combination machine tool when in use.

[0034] Furthermore, a clamping assembly is provided inside the closed frame 1, and a welding assembly is provided above the closed frame 1. The steel plate to be processed is positioned and clamped by the clamping assembly. At the same time, the welding positions of the two steel plates are calibrated inside the closed frame 1 according to the welding positions of the steel plates to be processed, so as to improve the welding accuracy of the steel plates. After the docking calibration of the welding positions of the steel plates to be processed is completed by the clamping assembly, the inclination angle of the steel plates to be processed is controlled so that the steel plates to be processed are in an inclined state, and the steel plates to be processed are automatically welded by cooperating with the welding assembly provided on the top of the closed frame 1. The welding position of the steel plate to be processed is obtained by an industrial CCD camera provided above the closed frame 1, and the coordinate value of the welding area is obtained by using analysis software, and the coordinate value parameters are input into the controller of the welding assembly, so as to control the welding assembly to realize automatic welding processing of the steel plate to be processed, which solves the problems of low welding efficiency and high labor intensity in the prior art of fixing and limiting the steel plates to be processed and then welding the steel plates to be processed by manual welding.

[0035] Furthermore, a cleaning component is provided above the interior of the closed frame 1, through which the impurities in the welding area of ​​the steel plate to be processed are cleaned before welding, so as to prevent the impurities in the welding area from affecting the welding accuracy. At the same time, the cleaning component is also used to absorb the welding smoke of the steel plate during the welding process, and the cleaning component can also be used to preheat the welding area of ​​the steel plate before welding, thereby greatly improving the subsequent welding processing accuracy of the steel plate.

[0036] Furthermore, the welding assembly includes a rotating seat 8, a driving arm 9, an electric telescopic arm 10 and a welding gun 11. An electric slide 6 is fixedly arranged on the rear side of the top of the inner wall of the closed frame 1, and a sliding block 7 is slidably arranged at the bottom of the electric slide 6. A rotating seat 8 is rotatably arranged at the bottom of the sliding block 7, and the rotating seat 8 is driven to rotate by a motor arranged on one side of the sliding block 7. A driving arm 9 is rotatably arranged at the bottom of the rotating seat 8 through an electric rotator, and an electric telescopic arm 10 is rotatably arranged at the bottom of the driving arm 9 through an electric rotator. A welding gun 11 is rotatably arranged at one end of the electric telescopic arm 10, and a motor for driving the welding gun 11 to rotate is also arranged inside the electric telescopic arm 10.

[0037] It should be noted that the welding assembly is driven by the electric slide 6 to slide left and right inside the closed frame 1, and the multi-angle operation of the welding gun 11 is realized in conjunction with the rotating seat 8, the driving arm 9 and the electric telescopic arm 10. When welding the steel plate, the position of the welding gun 11 is adjusted according to the position of the welding area. By pre-inputting the working path of the welding gun 11, the welding gun 11 can complete the automatic welding of the steel plate according to the path parameters without manual auxiliary operation. On the one hand, it avoids the harm to the health of humans during the steel plate welding process. On the other hand, it can also improve the welding stability of the steel plate to a certain extent, thereby ensuring the welding accuracy of the steel plate.

[0038] Embodiment 2:

[0039] Further, the material clamping assembly includes a connecting frame 18 and a limiting clamp block 20, the front and rear sides of the inner wall of the closed frame 1 are fixedly provided with an electric slide 2 12, and the opposite sides of the two electric slides 12 are slidably provided with four sliding frames 14, the upper and lower parts of the front and rear sides of the inner wall of the closed frame 1 are fixedly provided with limiting frames 13, and one side of the sliding frame 14 is respectively slidably connected with the inside of the two limiting frames 13 at the upper and lower parts, and the two limiting frames 13 are used to further improve the stability of the sliding frame 14 during the sliding process;

[0040] The two sliding frames 14 opposite to each other on the front and rear sides are configured as a group of clamping parts, and a total of four groups of clamping parts are arranged between the two electric slides 12. The opposite sides of the two sliding frames 14 in one group of clamping parts are fixedly provided with electric slides 3 15, and the opposite sides of the two electric slides 3 15 are slidably provided with two movable blocks 16, the opposite surfaces of the two movable blocks 16 located on the front and rear sides are rotatably provided with rotating blocks 17, and a connecting frame 18 is fixedly arranged between the opposite sides of the two rotating blocks 17, two connecting frames 18 are symmetrically arranged between the two sliding frames 14, and the opposite sides of the two connecting frames 18 are fixedly provided with electric slides 4 19, and the front and rear sides of the surface of the electric slide 4 19 are slidably provided with limit clamps 20.

[0041] It should be noted that when the steel plate is being processed by the automated welding process, the steel plate to be processed is transported to the left side of the closed frame 1 by the conveying frame 2 on the left. At this time, the closed baffle 5 inside the left material guide port 3 is controlled to fall down, so that the right side of the steel plate to be processed is in contact with the side of the closed baffle 5 on the left. The closed baffle 5 is used to straighten the steel plate entering the closed frame 1. Then, the closed baffle 5 on the left is controlled to be lifted upward, and the steel plate is sent into the closed frame 1 by the conveying frame 2 on the left. At this time, the four groups of clamps inside the closed frame 1 are controlled to move to the leftmost side of the closed frame 1 under the drive of the electric slide 2 12. The right side of the steel plate entering the closed frame 1 is clamped by the rightmost clamping piece, and the upper and lower movable blocks 16 are controlled by the electric slide 3 15 to move relatively. Driven by the upper and lower movable blocks 16, the upper and lower connecting frames 18 clamp the upper and lower sides of the right side of the steel plate. At the same time, the electric slide 4 19 arranged on the opposite side of the two connecting frames 18 controls the front and rear limit clamping blocks 20 to clamp and fix the front and rear sides of the steel plate. At this point, the right side of the steel plate is clamped and positioned, and the rightmost clamping piece is controlled to move to the right side of the closed frame 1. After the left side of the steel plate is pulled to the second set of clamping pieces on the right side, the steel plate is clamped and positioned. The left side of the steel plate is clamped and fixed in the same manner by the second set of clamps on the right side, thus completing the clamping and positioning of the first steel plate. The second steel plate is clamped and positioned in the same manner by the two sets of clamps on the left side. The two opposite sides of the two steel plates are brought into contact under the control of the electric slide 12. Then, the movable block 16 at the rear side is controlled to move downward. At this time, the rotating blocks 17 on both sides of the connecting frame 18 rotate inside the movable blocks 16 on the front and rear sides respectively, so that the connecting frame 18 is tilted inside the closed frame 1. At this time, the two steel plates to be processed are in a tilted state with the front side higher than the rear side, and the welding gun 11 in the welding assembly is used. The two steel plates are automatically welded. Since the steel plates are in an inclined state, the welding slag generated during the welding process will fall along the steel plates to the bottom of the closed frame 1 to prevent the welding slag from adhering to the steel plates and being shaped after cooling, which would affect the quality of the welded steel plates. After the welding of the steel plates is completed, the leftmost clamp is used to send the welded steel plates through the right material guide port 3 to the right conveyor frame 2. The conveyor frame 2 is used to automatically discharge the steel plates after the welding process. There is no need for manual auxiliary unloading, so that the automatic continuous welding of the steel plates is realized, which greatly improves the welding efficiency of the steel plates.

[0045] It should be noted that before the welding process of the steel plate is carried out, the electric slide 5 21 controls the sliding block 22 to move left and right, and at the same time, the steering motor 24 and the servo electric cylinder 25 are used to adjust the position of the cleaning frame 26, so that the cleaning brush 27 at the bottom of the cleaning frame 26 is in contact with the upper surface of the steel plate, and the cleaning frame 26 is controlled to slide on the surface of the steel plate, and the impurities on the surface of the steel plate are cleaned by the cleaning brush 27. At this time, the cleaning liquid is sent into the interior of the air guide port 28 through the material guide interface 31 and the material guide pipe 29 to complete the impurities on the surface of the steel plate. After cleaning, hot air is introduced into the air guide port 28 through the material guide interface 31 and the material guide pipe 29 to preheat the welding area on the surface of the steel plate. Finally, when the steel plate is welded using the welding gun 11, the cleaning frame 26 is controlled to be on one side of the welding gun 11, and the smoke generated during the welding process is extracted using the material guide interface 31 and the material guide pipe 29. This can not only greatly improve the surface welding accuracy of the steel plate, but also improve the environmental protection of the welding processing combination machine tool and reduce the pollution of the welding process to the environment around the machine tool.
