Description

Technical Field

[0001] The present application relates to the field of welding technology, and in particular to an automated device for positioning, cutting and welding an inclined web member. Background Art

[0002] Diagonal braces are a common component in steel structures. They are usually used to connect primary beams and secondary beams, transfer horizontal loads, and provide overall stability to the structure. The geometry of diagonal braces is usually inclined to adapt to the geometric layout and load path of the structure.

[0003] The processing of diagonal web members includes steps such as material cutting, bending, end processing and welding. Each process is relatively independent and lacks an integrated continuous process. Whether it is welded by manual welding or welding equipment (such as the patent number CN111618464B "A kind of diagonal web-free assembled welding equipment"), the diagonal web must be accurately cut before welding. The cutting and welding processes are independent, and the transmission of materials between different processes takes a long time, which affects the production efficiency and the coordination between processes. In addition, during the welding process, since the rods are fixed and cannot be moved, manual operation is still relied on in most cases. Manual welding is difficult to perform long-term overhead welding and vertical welding, and the thermal deformation generated during the welding process will also affect the welding accuracy. At present, some welding equipment uses robotic arms for automated operations. Although the accuracy is improved, the purchase and maintenance costs of the robotic arms are high, the control programming is complex, and the load capacity is limited, which limits its application in long-term production.

DETAILED DESCRIPTION

[0027] The embodiment of the present application provides an automated equipment for positioning, cutting and welding of diagonal web members, thereby solving the technical problems of the inconsistency of the cutting and welding processes in the traditional diagonal web processing and the difficulty in ensuring the accuracy of manual welding, thereby achieving the technical effect of improving the processing efficiency and welding accuracy of the diagonal web members.

[0028] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 The embodiment of the present application provides an automated device for positioning, cutting and welding of oblique web rods, the device comprising: a control console 100, an arc protection cover 200, a discharge table 300, a buffer dropper 400, a special machine body 500 and a welding power source 600.

[0029] The control console is used to control the equipment.

[0030] Specifically, the control console 100 is the main interface for the operator to interact with the automated equipment for positioning, cutting and welding of diagonal web members, and can be laid out according to the actual situation on site. The control console 100 usually has input devices such as buttons, knobs, and touch screens, and the operator inputs various control instructions through these input devices to start, stop or adjust the operation of the equipment. The control console 100 receives the operator's input through the internal PLC (programmable logic controller) and converts it into a signal that the machine can understand, which is transmitted to the various execution components of the equipment via cables or wirelessly, such as the jump grabbing module 510, the centering positioning module 520, the welding module 560, etc.

[0031] The arc protection cover 200 is used to protect the processing process.

[0032] Specifically, the arc light generated during the welding process contains a large amount of ultraviolet and infrared rays, which are harmful to human skin and eyes, and long-term exposure may cause burns or other health problems. The arc protection cover 200 surrounds the welding area to prevent welding arc radiation and isolate smoke to protect the safety of operators and the surrounding environment.

[0033] like Figure 2 As shown, the discharge table 300 includes a conveying frame 310, a first angle seat 320, a proximity switch bracket 330, a first oblique web member 340 and a baffle 350, the first angle seat 320 is symmetrically fixed to the top of the square tube of the conveying frame 310, the baffle 350 is fixed to the inner side of the first angle seat 320, the first oblique web member 340 is placed on the upper surface of the conveying frame 310, and the proximity switch bracket 330 is fixed to one end of the conveying frame 310.

[0034] Furthermore, the conveying rack 310 described in the embodiment of the present application includes three groups of bottom square tubes, wherein the three groups of bottom square tubes are arranged at an inclination of 15° from high to low, and the proximity switch bracket 330 is fixed to the top of the bottom square tube with the lowest height, and the proximity switch bracket 330 is used to place the proximity switch contactor.

[0035] Specifically, the conveyor frame 310 is the main supporting structure of the discharge table 300, which is used to carry and convey the diagonal rods. The conveyor frame 310 is composed of three groups of bottom square tubes with gradually changing heights. These square tubes are arranged according to a certain height difference to form a 15° inclined surface. Gravity is used to assist the movement of the diagonal rods, so that the diagonal rods can slide naturally or be pushed to the next station during the conveying process. The first angle seat 320 and the baffle 350 are symmetrically fixed on both sides of the top of each square tube of the conveyor frame 310 by bolt connection to maintain the balance and stability of the structure. A proximity switch bracket 330 is fixed at the top of the bottom square tube with the lowest height of the conveyor frame 310, that is, at the position where the conveyor frame 310 and the special machine body 500 are partially docked. A proximity switch contactor is fixed on the proximity switch bracket 330. The proximity switch contactor is used to detect the position or state of the diagonal rods to control the conveying process.

[0036] The first oblique belly rod 340 is an oblique belly rod to be processed, which is placed on the upper surface of the conveying rack 310 and waits to be conveyed to the next processing link. When the first oblique belly rod 340 is placed on the conveying rack 310, due to the inclined arrangement of the bottom square tube, the oblique belly rod will slide along the conveying rack 310 under the action of gravity. The discharge table 300 can place twenty-five rods at a time, and these rods restrict each other from moving. The rear rod pushes the front rod to move, and at the same time improves the transportation efficiency of the rods. The baffles 350 on both sides play an auxiliary role in the whole process, guiding or restricting the movement of the oblique belly rod, ensuring that the oblique belly rod maintains the correct position during the transmission process and does not deviate from the transmission path. When the oblique belly rod slides to the position of the proximity switch, the proximity switch will be triggered and send a signal to the control system. When the control system detects that the next process, that is, the special machine body 500 can allow new rods to enter, the gate is opened to allow the rods to enter the next process. Through the above process, the rods can enter the discharge area automatically after processing to reduce manual operation and improve the overall processing efficiency.

[0037] Exemplarily, when the rod slides to the position close to the switch, if the number of rods inside the special machine body 500 reaches the upper limit of five processing rods, the contactor will not transmit an open command, allowing the remaining rods to continue to stay on the conveyor rack 310 waiting for the previous process. If the processing of some rods has been completed inside the special machine body 500, the contactor will transmit an open command to allow the rods on the conveyor rack 310 to slide into the bracket 517 of the special machine body 500, thereby completing the entire discharge process.

[0038] like Figure 3As shown, the buffer-type dropper 400 includes a base 410, a buffer block 420, a pin 430, a second angle seat 440, a threaded rod 450 and a spring 460. The second angle seat 440 is fixed to one end of the base 410, the buffer block 420 is connected to the second angle seat 440 through the pin 430, the threaded rod 450 is symmetrically fixed to both ends of the base 410, and the spring 460 is fixedly connected to the threaded rod 450.

[0039] Specifically, the base 410 provides basic support for the entire buffer-type dropper 400 to ensure structural stability. The buffer block 420 mainly plays a buffering role. Through its material and design, it absorbs the impact force during material dropping, reduces noise and vibration, and protects materials and equipment. The buffer block 420 is connected by a pin 430 and a second angle seat 440, allowing the buffer block 420 to swing within a certain range during impact, thereby increasing the buffering effect. The second angle seat 440 is used to position and support the buffer block 420. The spring 460 provides elastic support to further enhance the buffering effect and ensure that the material falls smoothly. The threaded rod 450 is symmetrically fixed at both ends of the base 410 and is fixedly connected to the spring 460 for fixing the spring 460. At the same time, the threaded structure allows the preload force of the spring 460 to be adjusted to meet the buffering requirements of different materials.

[0040] When there is no rod, the buffer block 420 is in the initial position and fits with the front end of the angle seat. When the rod is processed and transported out of the special machine body 500, it first contacts the buffer block 420. The rod is forced to move 180° circumferentially. After the buffer block 420 is forced, it swings through the pin 430 and compresses the spring 460. The spring 460 begins to stretch so that the buffer block 420 starts to move slowly circumferentially, so that the circumferential movement speed of the rod is controlled, significantly reducing the vibration and noise caused by the impact of the material, and avoiding unnecessary damage to the rod due to the excessive falling speed. After the rod leaves, the buffer block 420 and the spring 460 are no longer stressed and return to the initial state. By adjusting the preload of the spring 460 on the threaded rod 450, the stiffness of the buffer system can be changed to adapt to rods of different weights and shapes, ensuring the smoothness and safety of the blanking process.

[0041] Through the above-mentioned specific structure, the buffer type blanking device 400 effectively reduces the impact of the oblique belly rod during the blanking process, thereby protecting the equipment and the finished product.

[0042] like Figure 4As shown, the special machine body 500 includes a jump grabbing module 510, a centering and positioning module 520, a boring and milling cutting module 530, a casting platform 540, a process inspection module 550 and a welding module 560. The jump grabbing module 510 is used to move the oblique belly lever, the casting platform 540 is used to support the special machine body 500, the boring and milling cutting module 530 and the welding module 560 are symmetrically fixed at one end of the casting platform 540, the process inspection module 550 is fixed to the casting platform 540 by bolt connection, and the centering and positioning module 520 and the boring and milling cutting module 530 are correspondingly fixed at both ends of the casting platform 540.

[0043] Specifically, the jump grabbing module 510 is responsible for the movement of the diagonal lever and is the key to connecting various processing units, ensuring the efficient flow of the rod in the processing flow. The centering and positioning module 520 is used to accurately adjust the position of the diagonal lever to ensure the positioning accuracy before cutting. The boring and milling cutting module 530 performs cutting processing of the diagonal lever, including boring of holes and milling of surfaces, to achieve high-precision cutting processing. The casting platform 540 is the basic support of the entire special machine body 500, carrying each module to ensure the stability of the entire processing process. The process inspection module 550 is fixed to the casting platform 540 by bolts, and is used to perform quality inspection during the processing to ensure that the processing accuracy of each link meets the standards. The welding module 560 is symmetrically fixed to one end of the casting platform 540 with the boring and milling cutting module 530, and is responsible for the welding of the diagonal lever.

[0044] After the rod enters the special machine body 500, it is moved to each functional area by the jump grabbing module 510, and first enters the centering and positioning module 520 to perform initial positioning and fixing before cutting. After fixing, it can enter the boring and milling cutting module 530 to start cutting the two ends of the rod. After cutting is completed, it enters the process inspection module 550 to complete the initial positioning and fixing before welding, and finally enters the welding module 560 to perform the final welding work. The special machine body 500 realizes the fully automatic processing of the oblique belly lever from raw materials to finished products through the efficient collaborative work of the above modules. After the rod is processed, it enters the buffer dropper 400.

[0045] The welding power source 600 is used to provide electrical energy to the welding module 560 of the equipment. Two welding power sources 600 are provided to meet the power demand of the welding module 560 .

[0046] Further, such as Figure 5As shown, the jump grasping module 510 of the embodiment of the present application includes: a motor 511, a first motor shaft 512, a second motor shaft 513, a third motor shaft 514, a swing arm 515, a shaft 516, a bracket 517 and a third angle seat 518, the bracket 517 and the swing arm 515 are connected to the first motor shaft 512 or the second motor shaft 513, the third motor shaft 514 through the shaft 516, and are fixed in the reserved hole of the third angle seat 518, and the motor 511 is connected to the first motor shaft 512 through a synchronous belt.

[0047] Specifically, the motor 511 is the power source of the entire jump grabbing module 510, providing power through rotation to drive the movement of the entire module. The first motor shaft 512, the second motor shaft 513, and the third motor shaft 514 are the output shafts of the motor 511, which are connected to the motor 511 through a synchronous belt or other transmission methods, and the rotational power of the motor 511 is transmitted to the swing arm 515 and the bracket 517. The swing arm 515 is a component used to realize the grabbing action in the jump grabbing module 510. It is connected to the motor shaft through a connecting shaft 516, and swings under the drive of the motor 511, thereby realizing the action of grabbing and releasing the oblique belly rod. The shaft 516 is used to connect the swing arm 515 and the bracket 517, and transmits the power of the motor shaft to the swing arm 515 and the bracket 517. The bracket 517 is used to support and fix the rod. The third corner seat 518 is the fixing point of the entire jump grab module 510, and it fixes the bracket 517 and the swing arm 515 in the appropriate position through the reserved holes.

[0048] After the motor 511 is powered on, the first motor shaft 512 starts to rotate through the synchronous belt. The movement of the first motor shaft 512 enables the swing arm 515 and the bracket 517 connected by the shaft to perform a full circle of 360°, thereby moving the rod on the bracket 517 to the predetermined position of each processing step. When the predetermined position is reached, the proximity switch on the proximity switch bracket 330 will control the motor 511 to stop power supply, and the swing arm 515 and the bracket 517 will also stop moving, so that the rod reaches the predetermined position.

[0049] By jumping and grabbing the module 510, the rods fed from the material discharging table 300 can be sent to the predetermined position before each processing step through the grooves left on the bracket 517, thereby realizing the transfer of the rods between the modules of the special machine body 500.

[0050] Further, such as Figure 6As shown, the centering and positioning module 520 of the embodiment of the present application includes a linear slide rail 521, a first slide plate 522, a centering angle seat 523, a first V-shaped positioning block 524, a centering clamping cylinder 525, a reference stop block 526 and a positioning stop block 527. The first slide plate 522 slides on the upper surface of the linear slide rail 521, the first slide plate 522 is fixed to one side of the centering angle seat 523, the reference stop block 526 is fixed to the top of the centering angle seat 523, the positioning stop block 527 is fixed to the running direction end of the centering clamping cylinder 525, and the first V-shaped positioning block 524 is fixed to the surface of the centering angle seat 523.

[0051] Specifically, the linear slide 521 provides a guide path for the first slide 522 to ensure smooth movement during the positioning process. The first slide 522 slides on the linear slide 521, carrying the centering angle seat 523 to achieve horizontal movement. The centering angle seat 523 is the core component of the positioning module, on which the first V-shaped positioning block 524 and the reference block 526 are carried. The first V-shaped positioning block 524 is used for the preliminary positioning of the rod, and its V-shaped design can adapt to the shape of the rod and provide stable support. The positioning block 527 is fixed to the running direction end of the centering clamping cylinder 525, directly contacts the rod, and is driven by the centering clamping cylinder 525 to achieve precise clamping of the rod. The reference block 526 cooperates with the positioning block 527 to complete the final positioning of the rod.

[0052] The rod is placed on the first V-shaped positioning blocks 524 at both ends of the centering angle seat 523 to initially fix the position. The first slide plate 522 moves horizontally toward the rod on the linear slide rail 521 to ensure close contact between the V-shaped positioning block and the rod. The centering clamping cylinder 525 is started to push the positioning block 527 to move toward the reference block 526 until the two blocks contact the rod and apply appropriate pressure to complete precise centering and positioning. Before the rod enters the boring and milling cutting module 530, the centering and positioning module 520 performs centering correction on the rod to be processed to ensure the stability of the rod and the accuracy of the rod position.

[0053] Further, such as Figure 7As shown, the boring and milling cutting module 530 of the present application embodiment includes a spindle motor 531, a spindle 532, a second oblique web member 533, a slide motor 534, a slide rail 535, a slide base 536, a slide 537, a first travel switch 538, a photoelectric sensor 539, a positioning fixture 5310, a centering vise 5311 and a cutter disc 5312, wherein the slide rail 535 is fixed to the upper surface of the slide base 536, the slide 537 slides on the surface of the slide rail 535, and the slide motor 534 is connected to the slide 537. The spindle 532 is fixed to the side of the slide 537, the spindle motor 531 is connected to the spindle 532, the centering vise 5311 is fixed to the casting platform 540, the positioning fixture 5310 is connected to the centering vise 5311 by bolts, the second oblique web rod 533 is placed in the positioning fixture 5310, the tool disc 5312 is symmetrically fixed to the two ends of the spindle 532, and the first travel switch 538 and the photoelectric sensor 539 are fixed to the slide 537.

[0054] Specifically, the spindle motor 531 is connected to the spindle 532, driving the spindle 532 to rotate at high speed, driving the cutter disc 5312 to perform cutting operations. The slide motor 534 drives the slide 537 to move along the slide rail 535 to achieve horizontal positioning and movement of the spindle 532 and the cutter disc 5312. The centering vise 5311 is fixed on the casting platform 540 and is used to accurately clamp and position the rod. The positioning fixture 5310 is connected to the centering vise 5311 by bolts, which is suitable for rods of different sizes to ensure stable clamping. The second oblique belly rod 533 is a rod to be cut and is placed in the positioning fixture 5310. The cutter disc 5312 is symmetrically fixed at both ends of the spindle 532 and is equipped with a customized tool modified from the A45.02 standard milling cutter disc 5312 for cutting. The first travel switch 538 and the photoelectric sensor 539 are used to monitor the position of the slide 537 and the state of the rod to ensure accurate processing.

[0055] After the rod is aligned and positioned, it is first placed on the positioning fixture 5310, and the slide motor 534 is started to push the slide 537 with the main shaft 532 to start moving the rod axially toward the rod position. When the photoelectric sensor 539 detects that the second oblique web rod 533 is in place, it sends a signal to control the pneumatic control device of the centering vise 5311 to open the clamp body of the centering vise 5311, so that the rod enters the slot. After the rod enters the slot, the photoelectric sensor 539 sends a signal again to control the clamp body to contract, clamp the rod, and complete the positioning and fixing.

[0056] After the fixation is completed, the spindle motor 531 starts, driving the front end cutter disc 5312 of the spindle 532 to rotate at high speed, ready for cutting. The slide motor 534 drives the slide 537, and the spindle 532 and the cutter disc 5312 move horizontally along the axial direction of the rod to accurately cut the second oblique belly rod 533. The cutter disc 5312 is customized according to the pipe diameter and chamfer size of the workpiece, and the blade uses the Yaken ADMX170508R-XM universal standard blade to complete the same level cutting of different rods. The unified tool can replace the blade without changing the cutting parameters, ensuring the stability of the cutting process.

[0057] Through the coordinated work of the above components, the boring and milling cutting module 530 can process rods of different sizes and different groove requirements, thereby achieving efficient and precise processing of different inclined-web rods and improving the accuracy of the cutting process.

[0058] Further, such as Figure 8 As shown, the process inspection module 550 of the embodiment of the present application includes a support plate 551, a second slide plate 552, an inspection angle seat 553, a detection block 554, an inspection cylinder 555, a displacement sensor 556, and a second V-shaped positioning block 557.

[0059] Specifically, the support plate 551 is fixed to the casting platform 540 by bolts, providing a solid foundation for the entire process inspection module 550. The second slide plate 552 slides on the support plate 551 to achieve lateral translation and complete the preliminary positioning of the rod. The inspection angle seat 553 is fixed on the second slide plate 552 as a fixed part of the inspection module, supporting and fixing other inspection components, and carrying a second V-shaped positioning block 557, a detection block 554, an inspection cylinder 555 and a displacement sensor 556. The detection block 554 is connected to the inspection cylinder 555, and the inspection cylinder 555 drives the detection block 554 to move to achieve precise alignment and contact. The displacement sensor 556 monitors the relative position between the detection block 554 and the rod to determine the position of the rod. The second V-shaped positioning block 557 is used for positioning support of the rod.

[0060] After the rod is grooved, the second slide plate 552 moves horizontally on the support plate 551 to roughly position the rod. At this time, the rod is placed on the second V-shaped positioning block 557, and the inspection cylinder 555 is started to push the detection block 554 to move toward the rod until the detection block 554 contacts the rod. During the movement of the detection block 554, the displacement sensor 556 receives the position signal of the rod, and determines whether the rod meets the position requirements before welding based on the signal of the displacement sensor 556. After the inspection is completed, the rod can proceed to the next step of welding.

[0061] After the groove cutting of the rod is completed, the process inspection module 550 repositions the rod to start the next welding work, realizing automatic inspection of the rod after processing and ensuring the positioning accuracy before welding.

[0062] Further, such as Fig. 9 As shown, the welding module 560 of the embodiment of the present application includes a servo motor 561, a push rod 562, a reducer 563, a welding oscillating welder 564, a cylinder 565, a welding gun 566, a second stroke switch 567, a welding positioning seat 568, a roller clamp 569, a clamp cylinder 5610, an inductive proximity switch 5611, a welding angle seat 5612 and a connecting piece 5613, wherein the welding angle seat 5612 is fixed to the casting platform 540, the welding positioning seat 568 is fixed to the casting platform 540 by bolts, the clamp cylinder 5610 is fixed to the upper surface of the welding positioning seat 568, and the roller clamp 569 is vertically fixed to the side of the clamp cylinder 5610. The inductive proximity switch 5611 is fixed on the welding angle seat 5612, the servo motor 561 is connected to the push rod 562 of the welding angle seat 5612 through the connecting piece 5613, the push rod 562 is fixed to one side of the welding angle seat 5612, the reducer 563 is fixed to the welding angle seat 5612, the second travel switch 567 is fixed to the welding angle seat 5612 through a connecting plate, the welding oscillating welder 564 and the welding gun 566 are fixed to the welding angle seat 5612 through a connecting block, the cylinder 565 is connected to the welding gun 566, and the cylinder 565 is fixed to the upper surface of the welding angle seat 5612.

[0063] Furthermore, two rollers are symmetrically arranged at both ends of the roller clamp in the welding module 560 of the embodiment of the present application.

[0064] The servo motor 561 is the power source of the welding module 560, and is used to drive the push rod 562 and the welding angle seat 5612 to perform linear motion along the axial direction of the rod. The push rod 562 connects the servo motor 561 and the welding angle seat 5612, transmits the power of the servo motor 561, and moves the welding angle seat 5612. The reducer 563 is used to reduce the speed of the servo motor 561 and increase the torque so as to more accurately control the movement of the welding angle seat 5612. The welding oscillator 564 is used to control the swing of the welding gun 566 to achieve weld tracking during the welding process. The cylinder 565 is used to push the welding gun 566 to move longitudinally so as to perform welding at different welding positions. The welding gun 566 is a tool for welding operations, which is used to generate a welding heat source, melt and connect metals. The second travel switch 567 is used to detect the position of the welding angle seat 5612 in the axial direction of the rod, and when the predetermined welding position is reached, the welding angle seat 5612 stops moving. The welding positioning seat 568 is fixed on the casting platform 540 to provide support for the clamping cylinder 5610. The roller clamp 569 is used to clamp the diagonal web rod to ensure stability during welding. The clamping cylinder 5610 is used to drive the opening and closing of the roller clamp 569 to clamp or release the rod. The inductive proximity switch 5611 is used to detect the longitudinal position of the welding gun 566, and when the predetermined welding position is reached, the movement of the welding gun 566 is stopped. The welding angle seat 5612 is the main supporting structure of the welding module 560, fixed on the casting platform 540, and supports other welding components. The connector 5613 is used to connect the servo motor 561 and the push rod 562 to transmit power.

[0065] Before starting the welding operation, the rod is first placed at the roller clamp 569 of the welding positioning seat 568. There are rollers at both ends of the clamp. During the placement of the rod, the rod slowly enters until the positioning is completed through the sliding of the roller and the cooperation of the clamp cylinder 5610. Then, the servo motor 561 is started, and the welding angle seat 5612 is pushed to move linearly along the axial direction of the rod through the connecting piece 5613 and the push rod 562 until the second stroke switch 567 detects that the welding angle seat 5612 reaches the predetermined position, at which time the welding angle seat 5612 stops moving. The cylinder 565 pushes the welding gun 566 and the welding oscillator 564 to move longitudinally until the inductive proximity switch 5611 receives a signal indicating that the welding gun 566 has reached the predetermined welding position, at which time the longitudinal movement stops. The welding gun 566 starts the welding operation, and the welding oscillator 564 adjusts the swing of the welding gun 566 as needed to achieve a uniform weld.

[0066] Through the above process, the welding module 560 realizes automatic positioning, clamping and welding of the rod to cope with different rod lengths and welding position requirements, and ensure welding quality and welding stability.
