Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of steel component displacement welding fixture, and particularly relates to a steel structure component displacement welding fixture. BACKGROUND

[0002] At present, the displacement operation for welding reinforcing ribs of large H-shaped steel components in the industry mainly adopts collaborative operation of double displacement machines. First, the hoisting equipment is used to hoist the H-shaped steel component to be processed to two independently arranged displacement machines. The clamping mechanism of the displacement machine is used to firmly clamp and fix the two ends or specified support points of the H-shaped steel component, so as to ensure that the component does not move during welding. After the welding of the reinforcing ribs on one side of the H-shaped steel component is completed, the two displacement machines are driven to rotate the H-shaped steel component around the preset axis synchronously by the control system, so as to realize the turning of the component and facilitate the welding of the reinforcing ribs on the other side.

[0003] Since the two displacement machines are independent driving units, there are inherent differences in the response characteristics of their mechanical transmission systems and control systems, and high-precision synchronous control algorithms are required to realize collaborative action. However, in actual working conditions, affected by factors such as load fluctuation, mechanical wear, and electrical signal delay, it is easy to cause the two displacement machines to move out of sync. Once the synchronization deviation exceeds the allowable range, not only will additional torque or shear force be generated on the H-shaped steel component, but also the displacement machine clamping mechanism will be overloaded, the transmission components will be stuck or even broken, which will significantly reduce the service life of the equipment and increase the frequency of downtime maintenance. In the prior art, a single larger power displacement machine can also be used to complete the fixing and displacement work independently, but the overall manufacturing cost of the equipment will increase dramatically, which is difficult to apply to small and medium-sized processing enterprises or production scenes with limited space.

[0004] Therefore, there is an urgent need for a steel structure component displacement welding fixture that can ensure the synchronization of H-shaped steel component displacement while reducing equipment investment and maintenance costs. SUMMARY

[0027] The following is in conjunction with the appendix Figure 1 -Appendix Figure 9 This application will now be described in further detail.

[0028] Please refer to the following: Figure 1 and Figure 2 A displacement welding fixture for steel structure components, used in conjunction with external welding equipment, such as... Figure 9 As shown. The fixture includes a base 1, a sliding mechanism 2 on the base 1, three mounting seats 3 evenly distributed front and back on the sliding mechanism 2, a displacement traction mechanism 4 on the middle mounting seat 3, and a clamping rotation mechanism 5 on both the front and back mounting seats 3.

[0029] In actual operation, the sliding mechanism 2 cooperates with the clamping and rotating mechanism 5 to fix the two ends of the H-beam steel component 14 in the center. While supporting the H-beam steel component 14, it can rotate the H-beam steel component 14. Then, when welding is required, the displacement traction mechanism 4 can easily complete the flipping and repositioning of the H-beam steel component 14.

[0030] See Figure 1 and Figure 2, the sliding mechanism 2 includes a slide rail 21 fixedly arranged on the base 1, a double-head screw 22 is rotationally arranged on the slide rail 21, the front and rear two mounting seats 3 are both threadedly connected with the double-head screw 22 through slide sleeves, and the two slide sleeves are opposite in the thread direction, a motor one (not shown in the figure) is fixedly arranged on the slide rail 21, an output shaft of the motor one is fixedly connected with one end of the double-head screw 22, and two guide rods one symmetrically arranged on the base 1 are slidably connected with the left and right two mounting seats 3, and the middle mounting seat 3 is fixedly connected with the slide rail 21. The double-head screw 22 is driven to rotate by the motor one, and the two slide sleeves drive the front and rear two mounting seats 3 to move close to each other.

[0031] Referring to Figure 1 and Figure 5-8 In order to reduce the driving force required by the displacement traction mechanism 4 when driving the H-shaped steel member 14 to overturn and displace while ensuring the welding stability of the H-shaped steel member 14, the clamping rotating mechanism 5 includes a support seat 51 fixedly arranged on the corresponding mounting seat 3, a rotating disc 52 is rotationally arranged on the opposite side of each of the two support seats 51, a locking assembly 53 is arranged on the support seat 51 to lock the rotating disc 52, a clamping disc 54 is fixedly connected with the opposite side of each of the two rotating discs 52 through a plurality of connecting columns, two clamping seats 55 symmetrically arranged above and below are slidably arranged on the opposite sides of each of the two clamping discs 54, the front and rear two clamping seats 55 located at the lower side are fixedly arranged on the side close to each other and used to support the outer extension end 12 of the H-shaped steel member 14, side limiting blocks 56 are slidably arranged on the left and right ends of the clamping seat 55, and a driving assembly three 57 is arranged on the clamping disc 54 and used to drive the corresponding clamping seat 55 and side limiting block 56 to move.

[0032] In specific work, the H-shaped steel member 14 (composed of two vertical flange plates and a horizontal web plate fixed between the two flange plates) is placed horizontally between the front and rear clamping discs 54 by external hoisting and transporting equipment, and the front and rear ends of the web plate of the H-shaped steel member 14 are placed on the outer extension ends 12 of the corresponding clamping seats 55, then the front and rear mounting seats 3 drive the front and rear support seats 51 to move close to each other under the drive of the double-headed screw rod 22, thereby driving the front and rear clamping discs 54 to move close to each other, and simultaneously driving the assembly three 57 to drive the upper and lower clamping seats 55 on the same clamping disc 54 to move close to each other and abut against the upper and lower surfaces of one end of the web plate of the H-shaped steel member 14, and the assembly three 57 also synchronously drives the left and right side limiting blocks 56 on the clamping seat 55 to move away from each other and abut against the inner side walls of the flange plates of the H-shaped steel member 14, so that the front and rear ends of the H-shaped steel member 14 abut against the surfaces of the two clamping discs 54 respectively, and the upper and lower sides of the front and rear ends of the web plate of the H-shaped steel member 14 are limited by the corresponding upper and lower clamping seats 55, and the inner sides of the left and right flange plates of the H-shaped steel member 14 are limited by the corresponding side limiting blocks 56, so that the H-shaped steel member 14 is finally centered and fixed between the front and rear clamping discs 54, at this time, the H-shaped steel member 14 as a whole can rotate together with the clamping disc 54 and the rotating disc 52, and is locked by the locking assembly 53. When welding, the H-shaped steel member 14 is further clamped and fixed by the displacement traction mechanism 4 to ensure the stability during welding.

[0033] When it is necessary to overturn and displace the H-shaped steel member 14, it is only necessary to first release the rotation locking of the clamping disc 54 by the locking assembly 53, and then overturn and displace the H-shaped steel member 14 by the displacement traction mechanism 4. Since the H-shaped steel member 14 as a whole is clamped and fixed by the two clamping discs 54, and the weight of the H-shaped steel member 14 is supported by the clamping disc 54, when the H-shaped steel member 14 is overturned and displaced, the welding stability can be ensured when the H-shaped steel member 14 is welded, and at the same time, the stable and rapid displacement of the H-shaped steel member 14 can be completed by an independent single displacement traction mechanism without increasing the traction power of the displacement traction mechanism 4, thereby reducing the equipment use cost.

[0034] Referring to Figure 6 , the side of the rotating disc 52 close to the corresponding support seat 51 is provided with a plurality of locking holes 9 uniformly distributed along the circumferential direction thereof, the locking assembly 53 comprises a locking pin 531 slidingly arranged on the left and right sides of the support seat 51, one end of the locking pin 531 is slidingly inserted into the corresponding locking hole 9, the other end of the locking pin 531 is fixedly provided with a ferromagnetic magnetic attraction plate 532, and the surface of the locking pin 531 is sleeved with a spring 533, both ends of the spring 533 are fixedly connected with the magnetic attraction plate 532 and the support seat 51 respectively, and a power electromagnetic suction disc 534 is fixedly arranged on the side wall of the support seat 51.

[0035] In normal state, the electromagnetic chuck 534 is powered off, the locking pin 531 is inserted into the locking hole 9 on the surface of the corresponding rotating disc 52 under the action of the natural recovery of the spring I 533, and the rotating disc 52 is positioned.

[0036] When the position changing traction mechanism 4 needs to traction the H-shaped steel member 14 to overturn and change position, the electromagnetic chuck 534 is powered on, the locking pin 531 is driven by the magnetic plate 532 to move away from the corresponding rotating disc 52, so that the locking pin 531 is separated from the corresponding locking hole 9, at this time the spring I 533 is in a compressed state, the rotating disc 52 is unlocked, and the clamping disc 54 can rotate.

[0037] It should be particularly pointed out that after the locking pin 531 is inserted into the locking hole 9 to position the rotating disc 52, although there is a small angular wobble error in the locked state, the position changing traction mechanism 4 will further lock the H-shaped steel member 14 in the subsequent welding process to eliminate the error.

[0038] Referring to Figure 5 , Figure 7 and Figure 8 , the surface of the clamping disc 54 is provided with a through hole, and two left-right symmetrical guide columns I 6 are fixedly arranged in the through hole. Two upper and lower sliding blocks 7 are movably sleeved on the two guide columns I 6, and the corresponding left and right sliding blocks 7 are fixedly connected with the corresponding clamping seat 55. The upper and lower ends of the guide column I 6 are further sleeved with a spring II 8, and the two ends of the spring II 8 are fixedly connected with the corresponding sliding block 7 and the inner wall of the through hole. The upper and lower clamping seats 55 on the same clamping disc 54 can slide up and down along the guide column I 6 under the driving of the driving assembly III 57 and the cooperation of the spring II 8.

[0039] Referring to Figure 7 , the side of each of the two clamping seats 55 away from each other is provided with two left-right symmetrical sliding grooves II, and the side limiting block 56 is slidably connected with the corresponding sliding groove II through a guide block 10, and a spring III 11 is fixedly arranged between one side of the guide block 10 and the inner wall of the corresponding sliding groove II. The side limiting block 56 can slide left and right along the corresponding sliding groove II through the guide block 10. In work, the driving assembly III 57 can drive the left and right side limiting blocks 56 on the same clamping seat 55 to slide left and right along the corresponding sliding groove II in cooperation with the spring III 11. When the guide block 10 moves to the inner wall of the sliding groove II in the corresponding sliding groove II, the guide block 10 moves to the limit distance, at this time the distance between the left and right side limiting blocks 56 on the clamping seat 55 is the distance between the inner side walls of the two flange plates of the H-shaped steel member 14 to be machined, and the two side limiting blocks 56 abut on the inner side walls of the two flange plates of the H-shaped steel member 14 to position the H-shaped steel member 14. And the surface of the side limiting block 56 in contact with the inner side wall of the flange plate of the H-shaped steel member 14 is rollingly provided with a plurality of rolling balls to reduce the friction when the two slide relative to each other.

[0040] Referring to Figure 5 , Figure 7 and Figure 8 , the driving assembly three 57 comprises a double-headed screw two 571 rotatably arranged in the through hole, two driving bases 572 with opposite screw directions threadedly connected on the double-headed screw two 571, and a driving plate 573 fixedly arranged on the driving base 572. The driving plate 573 is arranged as an inclined surface one near both ends of the corresponding two side limiting blocks 56, and the side limiting block 56 is arranged as an inclined surface two matching the inclined surface one near the side corresponding to the driving plate 573. A rotating shaft 574 is rotatably arranged on the side of the clamping disc 54 near the rotating disc 52 through the upper and lower two ear plates two, the lower end of the rotating shaft 574 is in transmission connection with the lower end of the double-headed screw two 571 through a gear set 575, and a motor three is also fixedly arranged on the side of the clamping disc 54 near the rotating disc 52. The output shaft of the motor three is fixedly connected with the upper end of the corresponding rotating shaft 574. The mutually far sides of the upper and lower corresponding two driving plates 573 in the same clamping disc 54 are slidably inserted with two left and right symmetrical guide columns two 13, and the guide column two 13 is fixedly connected with the corresponding clamping block 55 through the ear plate three.

[0041] In specific work, the double-headed screw two 571 is controlled to rotate through the motor three, so that the upper and lower two driving bases 572 drive the corresponding driving plates 573 to move close to each other. The upper and lower driving plates 573 move close to each other, so that the two end inclined surfaces one of the driving plate 573 abut against the inclined surfaces two of the corresponding left and right two side limiting blocks 56, thereby driving the left and right two side limiting blocks 56 on the same clamping block 55 to move away from each other. When the two side limiting blocks 56 are limited to slide to the limit position, the side limiting block 56 abuts against the inner side wall of the flange plate of the H-shaped steel member 14, and then the driving plate 573 continuously applies pressure to the side plate limiting block. At this time, the pressure is transmitted to the corresponding clamping block 55 through the side plate limiting block, and the upper and lower two clamping blocks 55 on the same clamping disc 54 are driven to move close to each other until the two clamping blocks 55 abut against the upper and lower sides of the web of the H-shaped steel member 14. At this time, the H-shaped steel member 14 is in the center position of the clamping disc 54, and the front and rear ends of the H-shaped steel member 14 are fixedly positioned and limited in all directions.

[0042] It should be particularly pointed out that the angles, roughness and hardness of the inclined surface one and the inclined surface two in the scheme are precisely calculated and designed by the personnel in the technical field, and force sensors are arranged at the corresponding contact points to confirm that the abutment is in place. At the same time, the spring one 533, the spring two 8 and the spring three 11 in the scheme are all made of high-performance materials, which can meet the cooperation between the structures in the scheme, and will be regularly maintained and replaced.

[0043] Referring to Figure 1 , Figure 3 and Figure 4, the displacement traction mechanism 4 includes a fixed seat 41 arranged above the corresponding mounting seat 3 and adjustable in height, the left and right sides of the intermediate mounting seat 3 are both fixedly provided with an electric push rod 46, the telescopic end of the electric push rod 46 is fixedly connected with the corresponding side wall of the fixed seat 41, a half-tooth ring 43 is rotationally arranged on the fixed seat 41 through a driving assembly one 42, and two clamping jaws 45 which are symmetrical and relatively slidable are arranged in the half-tooth ring 43 through a driving assembly two 44.

[0044] In specific work, before welding processing, the height of the half-tooth ring 43 is adjusted through the electric push rod 46, so that the central axis of the half-tooth ring 43 is in the same position as the central axes of the two clamping discs 54, and it is ensured that the half-tooth ring 43 does not interfere with the rotating disc 52 when rotating the H-shaped steel member 14. Then during processing, after the H-shaped steel member 14 is fixed between the two clamping discs 54, the two clamping jaws 45 are controlled to be close to each other and clamped on the outer side walls of the two flange plates of the H-shaped steel member 14 through the driving assembly two 44, so as to further fix the H-shaped steel member 14, and then the reinforcing ribs are welded on the H-shaped steel member 14 through the external welding equipment. When it is necessary to overturn and displace the H-shaped steel member 14, the locking assembly 53 releases the locking of the clamping disc 54, the half-tooth ring 43 drives the H-shaped steel member 14 to rotate forward by 90° through the driving assembly one 42, the locking assembly 53 locks the clamping disc 54 again, the two clamping jaws 45 are separated from the H-shaped steel member 14, the half-tooth ring 43 is driven to rotate reversely by 180° through the driving assembly one 42, so that the two clamping jaws 45 are rotated to the other side of the H-shaped steel member 14, and the two clamping jaws 45 are clamped on the outer side walls of the two flange plates of the H-shaped steel member 14 again. At this time, the locking assembly 53 releases the locking of the clamping disc 54, and drives the half-tooth ring 43 to rotate forward by 90° through the driving assembly one 42 to complete the overturning and displacement of the H-shaped steel member 14, and then the locking assembly 53 locks the clamping disc 54 again. The welding processing is performed on the other side of the H-shaped steel member 14.

[0045] Referring to Figure 3 and Figure 4 , the upper side of the fixed seat 41 is provided with a rotating groove, the driving assembly one 42 includes four transmission gears which are rotationally arranged in the rotating groove through connecting shafts, the half-tooth ring 43 is meshed with the four transmission gears, the same end of the four connecting shafts is movably extended to the outside of the fixed seat 41 and is commonly connected through a chain wheel set, a motor two (not shown in the figure) is fixedly arranged on the side of the fixed seat 41 away from the chain wheel set, and the output shaft of the motor two is fixedly connected with one end of one of the connecting shafts. One of the transmission gears is driven to rotate through the motor two, all the transmission gears are rotated through the chain wheel set, and the half-tooth ring 43 is driven to rotate through the transmission gear rotation, so as to control the H-shaped steel member 14 to overturn through the clamping jaw 45.

[0046] It needs to be specially pointed out that when the half tooth ring 43 is rotated to a certain angle and is completely separated from two transmission gears, because the four transmission gears are connected through the sprocket set, the four transmission gears keep synchronous rotation at all times, and when the half tooth ring 43 is reset in reverse rotation, the half tooth ring 43 can be stably clamped and engaged with the separated transmission gears.

[0047] Referring to Figure 3 and Figure 4 The driving assembly two 44 comprises a connecting plate 441 fixedly arranged in the inside of the half tooth ring 43, the connecting plate 441 is provided with a sliding groove one, the sliding groove one is fixedly provided with a guide rod two, the lower side of the two clamping jaws 45 is slidably connected with the guide rod two, the lower middle of the connecting plate 441 is fixedly provided with a double-shaft motor 442, the two output shafts of the double-shaft motor 442 are fixedly connected with one-way screws 443, the two one-way screws 443 are opposite in screw direction, the one-way screw 443 is threadedly connected with the corresponding clamping jaw 45, and the one-way screw 443 is rotationally connected with the connecting plate 441 through an ear plate one at the end away from the double-shaft motor 442. The two one-way screws 443 are driven to rotate simultaneously by the double-shaft motor 442, so that the two clamping jaws 45 are driven to move close to each other to clamp and fix the outer side walls of the two flange plates of the H-shaped steel member 14.

[0048] The steel structure member displacement welding clamp comprises a driving displacement traction mechanism 4 and two driven opposite clamping rotation mechanisms 5. The design utilizes the opposite clamping rotation mechanism 5 to realize automatic centering and all-direction stable clamping of the workpiece, and significantly improves the stability and precision of the welding process. Meanwhile, by distributing the main weight of the H-shaped steel member 14 workpiece on the driven opposite clamping rotation mechanism 5, the power requirement of the core driving unit is greatly reduced, thereby effectively reducing the equipment manufacturing cost and energy consumption on the premise of ensuring excellent performance. Compared with the traditional scheme of two standard independent displacement machines working cooperatively or the scheme of one super-power displacement machine working independently, the scheme avoids the problems of poor synchronism and additional stress caused by the use of double standard independent displacement machines, and avoids the problems of high equipment investment cost and difficult post-maintenance caused by the use of one super-power independent displacement machine.
