DETAILED DESCRIPTION

[0031] 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.

[0032] Embodiment 1, as Figure 1 As shown, an automated welding production line for iron tower components comprises an operating table 1, a fixing mechanism 2 is symmetrically slidably connected to the upper end of the operating table 1, a transmission mechanism 6 is fixedly connected to the middle of the upper end of the operating table 1, a feeding mechanism 7 is slidably connected to the rear side of the upper end of the operating table 1, a positioning mechanism 5 is symmetrically fixedly connected to the middle of the upper end of the operating table 1, a welding mechanism 4 is fixedly connected to the middle of the upper end of the operating table 1, and a rotating mechanism 3 is symmetrically arranged at the lower part of the welding mechanism 4.

[0033] When the cut and polished angle steel is welded by the device, the two fixing mechanisms 2 are first activated, and the cut and polished angle steel is placed on the upper part of the two fixing mechanisms 2 through the cooperation of the automatic loading device in the prior art, and then the two fixing mechanisms 2 drive the angle steel to be welded to move toward each other. During the movement, the angle steels on the left and right sides are rotated 30° toward the direction close to the unloading mechanism 7 through cooperation, and then the two positioning mechanisms 5 cooperate with the two fixing mechanisms 2. When the angle steel reaches the welding position, it automatically stops moving, and then the two angle steels are welded through the cooperation of the welding mechanism 4. After the welding is completed, the welding mechanism 4 cooperates with the two rotating mechanisms 3 to first automatically release the lock of the two fixing mechanisms 2 on the angle steel, and then the welding mechanism 4 cooperates with the unloading mechanism 7 to push the welded workpiece out for unloading, and then the two fixing mechanisms 2 can be reset, and then welding can be performed again.

[0034] See also Figure 2 and Figure 3 A motor 11 is fixedly connected to the middle part of the lower end of the operating table 1, and the output end of the motor 11 passes through the lower end of the horizontal part of the operating table 1 and extends to the upper end of the horizontal part of the operating table 1. A guide rail 12 is symmetrically fixedly connected to the middle part of the upper end of the operating table 1, a friction plate 13 is symmetrically fixedly connected to the rear side of the upper end of the operating table 1, a guide rail 14 is fixedly connected to the rear side of the middle part of the upper end of the operating table 1, and a receiving plate 15 is fixedly connected to the middle part of the upper end of the operating table 1. Limiting grooves 121 are provided on the upper ends of the two guide rails 12, and rectangular guide rods 122 are fixedly connected to the middle of one side of the two guide rails 12 close to each other.

[0035] Specifically, the two guide rails 12 cooperate to limit the movement of the two fixing mechanisms 2 to prevent deviation during the movement. At the same time, the two friction plates 13 cooperate with the two fixing mechanisms 2 to adjust the direction of the fixed angle steel.

[0036] During the operation of this embodiment, through the cooperation between the welding mechanism 4 and the rotating mechanism 3, the lock of the angle steel can be quickly released, and the welded workpiece can be pushed for unloading, thereby shortening the production cycle. At the same time, the cooperation between the friction plate 13 and the fixing mechanism 2 can adjust the angle during the movement of the angle steel, which can flexibly cope with the welding tasks of various tower components and improve the flexibility of production.

[0037] Embodiment 2: Based on Embodiment 1, this embodiment is designed to achieve the effect of pushing the workpiece out during the resetting of the welding head 43 after welding.

[0038] See also Figure 4The fixing mechanism 2 includes T-shaped blocks 21 which are respectively slidably connected to the inner surfaces of the two limiting grooves 121, the upper ends of the two T-shaped blocks 21 are commonly fixedly connected with a rectangular block 22, the upper ends of the rectangular blocks 22 are symmetrically fixedly connected with a round rod 23, the upper ends of the two round rods 23 are commonly slidably connected with a disc 24, the middle part of the upper end of the disc 24 is fixedly connected with an electric permanent magnetic suction cup 25, and the side of the electric permanent magnetic suction cup 25 close to the friction plate 13 is electrically connected with a power-on button 26.

[0039] The above-mentioned permanent magnetic suction cup 25 is a conventional design in the prior art. Its principle is that when a positive current pulse is passed through, a magnetic field will be generated around it. When a reverse current pulse is passed through it, it is in a demagnetized and relaxed state, and the workpiece can be removed smoothly. At the same time, the power-on button 26 is a button for controlling the passage of positive and reverse current pulses into the permanent magnetic suction cup 25. Similarly, the power-on button 26 is connected to an external power supply.

[0040] Specifically, when preparing to weld two angle steels, first press the power-on button 26 once to make the electric permanent magnetic suction cup 25 as a whole have strong magnetism, and then place the cut and polished angle steel on the upper end of the electric permanent magnetic suction cup 25 through the picking device in the prior art, and then use the disc 24 to cooperate with the round rod 23 and the two T-shaped blocks 21 to move the two angle steels toward each other.

[0041] See also Figure 5 The transmission mechanism 6 includes a rotating shaft 61 fixedly connected to the output end of the motor 11, a gear 1 62 is fixedly connected to the outer surface of the rotating shaft 61, and a rack 1 63 is symmetrically meshed on the outer surface of the gear 1 62.

[0042] Specifically, when the angle steel is placed on the upper end of the permanent magnetic chuck 25, the motor 11 is excited, and then the output end of the motor 11 drives the shaft 61 to rotate, and then drives the gear 1 62 to rotate, and then the two racks 1 63 move toward each other.

[0043] See also Figure 6 A slide groove 632 is provided on the side of the two racks 63 away from each other, and the inner surfaces of the two slide grooves 632 are slidably connected to the matching rectangular guide rods 122 respectively. Two limit blocks 631 are fixedly connected to the upper ends of the two racks 63, and the two limit blocks 631 on the same side are tightly attached to the rectangular block 22.

[0044] Furthermore, when the two racks 1 63 are driven to move toward one side close to each other along the rectangular guide rod 122, the two limit blocks 631 on the same side cooperate to clamp the rectangular block 22, so that the rectangular block 22 is driven to move in the same direction as the rack 1 63. When the rectangular block 22 is driven to move, the two T-shaped blocks 21 slide in the same direction along the inner surface of the limit groove 121, and at the same time, the two round rods 23, the disc 24 and the permanent magnetic chuck 25 are driven to move in the same direction.

[0045] Furthermore, in the process of rack 1 63 driving the electric permanent magnetic suction cup 25 and the angle steel to move toward the middle through two limit blocks 631, when the outer surface of the disc 24 contacts the front end of the friction plate 13 on the same side, the disc 24 continues to be driven to move, and then through the cooperation of the friction plate 13, the disc 24 drives the electric permanent magnetic suction cup 25, the power button 26 and the angle steel to rotate 30° to the rear side, and then the disc 24 disengages from the front side of the friction plate 13, and the angle steel maintains the rotated state and is driven to continue to move toward the middle.

[0046] See also Fig. 9 The positioning mechanism 5 includes an L-shaped plate 51 fixedly connected to the upper end of the operating table 1, a plurality of springs 52 are fixedly connected to one side of the horizontal part of the L-shaped plate 51, a plurality of springs 52 are fixedly connected to a transverse plate 53, and a sensor 511 is fixedly connected to one side of the horizontal part of the L-shaped plate 51.

[0047] The sensor 511 mentioned above is of conventional design in the prior art. When it is touched, the collected information is connected to an external processing system to control the operation of the motor 11.

[0048] Specifically, when the rack 63 drives the rectangular block 22 to move toward the middle, when the rectangular block 22 moves to be close to one side of the cross plate 53, the rectangular block 22 continues to move, and then pushes the cross plate 53 in the same direction, so that the plurality of springs 52 are compressed until the plurality of springs 52 are compressed to the shortest point. At this time, one end of the cross plate 53 close to the L-shaped plate 51 contacts the sensor 511. At this time, the sensor 511 receives the information and transmits the information to the processing system in the prior art, which immediately stops the motor 11. At this time, the angle steels at the upper ends of the two electro-permanent magnetic suction cups 25 are just located above the receiving plate 15, and the two angle steels are close to each other.

[0049] See also Figure 7 The welding mechanism 4 includes a hydraulic cylinder 41 fixedly connected to the middle part of the upper end of the operating table 1, a push plate 42 is fixedly connected to the output end of the hydraulic cylinder 41, a welding head 43 is fixedly connected to the lower end of the push plate 42, a rack 421 is fixedly connected to the rear sides of the left and right ends of the push plate 42, and a slide rod 422 is fixedly connected to the rear end of the push plate 42.

[0050] When the two angle steels are driven to move toward the middle, the hydraulic cylinder 41 is activated, so that its output end pushes the push plate 42 downward, thereby driving the welding head 43 to move downward. The push plate 42 drives the two racks 421 and the slide bar 422 to move in the same direction during the movement. When the output end of the hydraulic cylinder 41 pushes the welding head 43 down to a suitable position, it stops moving.

[0051] Then, the welding head 43 is activated to weld the two angle steels at the upper end of the receiving plate 15 .

[0052] See also Figure 8The rotating mechanism 3 includes a roller 1 31 rotatably connected to the upper end of the operating table 1, a gear 2 32 is fixedly connected to the middle of the outer surface of the roller 1 31, the gear 2 32 can mesh with the matching rack 2 421, and a roller 2 33 is transmission-connected to the front side of the outer surface of the roller 1 31, a circular plate 34 is fixedly connected to the lower end of the roller 2 33, a pressure plate 35 is fixedly connected to one side of the upper end of the circular plate 34, and the lower end of the circular plate 34 is rotatably connected to the upper end of the operating table 1.

[0053] The above-mentioned transfer roller 1 31 and the transfer roller 2 33 are meshed and driven by a bevel gear set in the prior art. When the transfer roller 1 31 is driven to rotate, the transfer roller 2 33 rotates at the same time.

[0054] Furthermore, when the push plate 42 pushes the welding head 43 to descend in preparation for welding, the two racks 421 engage with the gear 2 32 when descending, thereby causing the gear 2 32 to rotate, thereby causing the roller 1 31 to rotate, and then the roller 2 33 to rotate, and further, it will drive the circular plate 34 to rotate in the same direction, and then the pressure plate 35 will rotate to the rear side.

[0055] When welding is completed, the hydraulic cylinder 41 is stimulated so that its output end drives the push plate 42 and the welding head 43 to move upward, and then the rack 2 421 cooperates to reverse the gear 2 32, thereby causing the roller 2 33 and the circular plate 34 to rotate in the opposite direction, and then the pressure plate 35 rotates to the front side. During the rotation process, the pressure plate 35 presses the power button 26 once, thereby demagnetizing the electro-permanent magnetic suction cup 25 and releasing the lock on the diagonal steel.

[0056] See also Fig.10 The unloading mechanism 7 includes a rectangular slider 71 slidably connected to the outer surface of the guide rail 14, a triangular push block 72 is fixedly connected to the front end of the rectangular slider 71, an inclined groove 74 is opened at the left end of the rectangular slider 71, and the inner surface of the inclined groove 74 is slidably connected to the outer surface of the slide rod 422.

[0057] Furthermore, when the push plate 42 pushes the welding head 43 downward, the slide bar 422 slides along the inner surface of the inclined groove 74, thereby driving the rectangular slide block 71 to move backward along the outer surface of the guide rail 14, thereby driving the triangular push block 72 to move in the same direction;

[0058] When welding is completed, the slide bar 422 is driven upward by the push plate 42. At this time, the rack 2 421 cooperates with the gear 2 32 to release the lock of the electric permanent magnetic suction cup 25 on the angle steel, and then cooperates with the slide bar 422 through the inclined groove 74 to make the rectangular slider 71 and the triangular push block 72 move forward along the guide rail 14. During the forward movement of the triangular push block 72, the welded angle steel workpiece is gradually lifted upward, and then the welded workpiece automatically slides down for unloading, and then the two electric permanent magnetic suction cups 25 and the disc 24 are reset by the motor 11 for the next welding.

[0059] Therefore, this solution can accurately control the adsorption and release of the angle steel through the cooperation of the electric permanent magnetic suction cup 25, avoiding the displacement or deformation of the angle steel during the welding process. At the same time, the disc 24 and the friction plate 13 cooperate to adjust the angle during the movement of the angle steel, and can accurately control the angle change of the angle steel during the movement process, ensuring that the angle steel reaches a predetermined angle before welding. At the same time, the automated angle adjustment reduces manual intervention and downtime, and improves the overall efficiency of the production line. The design of the triangular push block 72 allows the angle steel workpiece to slide automatically after welding, reducing the time for manual unloading and further improving production efficiency. The automated welding production line reduces manual operation and reduces the risk of work-related accidents.

[0060] It should be noted that the specific installation method, circuit connection method and control method of the motor 11 and the hydraulic cylinder 41 used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0061] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected.
