Description

Technical Field

[0001] The invention relates to the technical field of bracket welding, in particular to a welding device for a tractor bracket component. Background Art

[0002] Currently in the field of welding of tractor bracket components, common welding devices often have many problems when welding a bracket body composed of I-beams and steel beams.

The above welding device is usually unable to flexibly adapt to the welding requirements of bracket bodies of different sizes, and it is difficult to accurately clamp and position the I-beams and steel beams, resulting in low welding accuracy. During the clamping process, the automatic centering and deviation correction functions cannot be realized, and additional equipment or manual adjustment is required, which increases the complexity and time cost of the operation. The lack of automatic spacing adjustment function cannot ensure that the I-beams in different types of brackets can always fit tightly with the ends of the steel beams, affecting the welding quality and reducing work efficiency.

DETAILED DESCRIPTION

[0033] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] like Figure 1-12The tractor bracket component welding device shown is used for welding a bracket body 3 composed of an I-beam 1 and a steel beam 2, wherein the steel beam 2 is vertically arranged at both ends of the I-beam 1, and the welding device includes a frame 4, a turning frame 5, a clamping mechanism 6, a spacing adjustment mechanism 7, a turning mechanism 8 and a pushing mechanism 9, wherein the turning frame 5 is rotatably arranged on the frame 4, the turning mechanism 8 is arranged on the side wall of the frame 4 and the output end is transmission-connected with the turning frame 5, the turning mechanism 8 is provided with two rotating disks 10 that rotate synchronously with the turning frame 5, and the rotating disk 10 is vertically installed on the side wall of the frame 4, and the clamping mechanism 6 includes a steel material mounting frame 11 arranged on the turning frame 5, a clamping assembly and a pushing mechanism 9 arranged on the rotating disk 10. A clamping drive assembly is transmission-connected to the clamping assembly, three steel mounting frames 11 are provided and are respectively located at the center and both sides of the turning frame 5, the steel mounting frame 11 located at the center of the turning frame 5 is fixedly connected to the turning frame 5, the steel mounting frames 11 located on both sides of the turning frame 5 are slidably connected to the turning frame 5, the spacing adjustment assembly includes a threaded sliding seat 12 which is slidably arranged on the turning frame 5 and transmission-connected to the steel mounting frames 11 on both sides, and a rotating drive assembly which is installed on the rotating disk 10 and transmission-connected to the threaded sliding seat 12, two groups of pushing mechanisms 9 for pushing the steel beam 2 are provided and are respectively installed on two rotating disks 10, and welding robots are provided at both ends of the side of the frame 4.

[0035] When the equipment is performing welding operations, it is necessary to clamp the transversely arranged I-beam 1 on the steel mounting frame 11 through the clamping mechanism 6, and install the steel beam 2 on the output end of the pushing mechanism 9. When the spacing adjustment mechanism 7 is working, it drives the steel mounting frames 11 located on both sides of the flip frame 5 to move toward or oppositely, thereby adjusting the distance between the steel mounting frames 11 at the center position, adapting to the welding clamping work of different bracket bodies 3, and ensuring that the I-beam 1 can fit with the end of the steel beam 2, so as to facilitate the subsequent precise welding work. The output of the rotary drive component drives the threaded sliding seat 12 to move longitudinally (consistent with the length direction of the steel beam 2), thereby driving the steel mounting frame 11 fixedly connected to the threaded sliding seat 12 to move synchronously, thereby realizing the adjustable spacing function. After the spacing adjustment is completed, the clamping mechanism 6 is driven to clamp the I-beam 1. The position of the clamped I-beam 1 in the longitudinal direction (consistent with the length direction of the steel beam 2) is determined. Since the direction of the I-beam 1 in the transverse direction (consistent with the length direction of the I-beam 1) is not accurate enough during the placement process, when the pushing mechanisms 9 at both ends synchronously push the steel beam 2 to the I-beam 1, the position of the I-beam 1 in the transverse direction can be automatically adjusted, thereby realizing the automatic centering function, and no additional equipment is required for adjustment. The flipping mechanism 8 is used to drive the flip frame 5 to realize the flipping function, and the rotating disk 10 that flips synchronously with the flip frame 5 can install the driving sources in the clamping drive assembly, the rotating drive assembly and the pushing mechanism 9 outside the flip frame 5, which can realize convenient installation and maintenance functions, reduce the number of driving sources, and enable the equipment to better realize the clamping function. The rotating disk 10 can rotate synchronously with the flip frame 5, which ensures that the driving sources installed on the rotating disk 10 can achieve relative stillness with the flip frame 5, and can still achieve accurate driving function after the flip frame 5 flips the angle. In the initial state, the welding robot can weld the top welding point of the steel beam 2 and the I-beam 1. At this time, the connection state of the steel beam 2 and the I-beam 1 is initially realized. The turning frame 5 turns ninety degrees. At this time, welding operations can be performed on the side and bottom of the connection between the steel beam 2 and the I-beam 1, realizing a firm and precise welding operation.

[0036] Each steel mounting frame 11 is provided with a plurality of groups of clamping assemblies, and a plurality of clamping positions are provided on the steel mounting frame 11 along its length direction, and each clamping position is symmetrically provided with two groups of clamping assemblies along the vertical center plane of the steel mounting frame 11. The clamping assembly includes a clamping plate 13, a downward pressure driving member, a clamping roller 14 and a fixed connecting frame 15. A central sliding groove 16 is opened at the center of the steel mounting frame 11 along the length direction of the I-beam 1. The output end of the clamping driving assembly passes through the central sliding groove 16 and is transmission-connected with the clamping plate 13 in the clamping assembly. The clamping roller 14 is vertically arranged, and the clamping roller 14 is rotatably mounted on the fixed connecting frame 15. The fixed connecting frame 15 is fixedly mounted on the side of the clamping plate 13 close to the I-beam 1, and the downward pressure driving member is elastically connected to the side of the clamping plate 13 close to the I-beam 1.

[0037] In the present device, the clamping drive assembly on each steel material mounting frame 11 can work synchronously under the drive of the clamping drive assembly, and the clamping drive assembly drives the first linear push rod 21 to slide in the central sliding groove 16 along the horizontal direction. The movement of the first linear push rod 21 drives the clamping plate 13 connected thereto to move. When the clamping plate 13 approaches the I-beam 1, the clamping roller 14 fixed on the clamping plate 13 clamps the I-beam 1. The clamping roller 14 can ensure that the I-beam 1 can still be adjusted in the horizontal direction while being clamped in the longitudinal direction. When the two steel beams 2 synchronously approach the center and contact the two ends of the I-beam 1, the I-beam 1 can be automatically corrected in the center. Through multiple clamping points and symmetrically arranged clamping assemblies, the I-beam 1 can be clamped more stably, ensuring that the position of the I-beam 1 will not be offset during the welding process, thereby improving the accuracy and quality of welding. At the same time, this clamping method can adapt to I-beams 1 of different sizes, thereby improving the versatility and applicability of the device.

[0038] The downward pressure driving component includes a conical roller 17, an elastic mounting frame 18, a first spring 19 and a pressure detection sensor 20. The elastic mounting frame 18 is slidably set on the clamping plate 13, and the pressure detection sensor 20 is fixedly installed on the clamping plate 13. The conical roller 17 is vertically rotatably installed on the elastic mounting frame 18. The diameter of the conical roller 17 gradually decreases from top to bottom. The first spring 19 is horizontally set, one end of the first spring 19 is fixedly connected to the elastic mounting frame 18, and the other end of the first spring 19 is fixedly connected to the clamping plate 13.

[0039] During the clamping process, when the I-beam 1 contacts the tapered roller 17, the I-beam 1 will push the tapered roller 17. Since the tapered roller 17 is mounted on the elastic mounting frame 18, the elastic mounting frame 18 will slide on the clamping plate 13 and compress the first spring 19. At the same time, the pressure detection sensor 20 will detect the pressure change. When the device is clamping, the I-beam 1 first hits the tapered roller 17, and then hits the clamping roller 14 after the first spring 19 is compressed. The pressure detection sensor 20 can detect the force. When the tapered roller 17 hits the top of the I-beam 1, due to its inclined direction, it will generate downward pressure on the I-beam 1 when clamping inward. This downward pressure can firmly press the I-beam 1 on the steel mounting frame 11, thereby improving the clamping effect on the I-beam 1 and ensuring welding accuracy.

[0040] The clamping drive assembly includes a first linear push rod 21, a first hinged rod 22, a horizontal sliding block 23 and a first pushing device. Three first linear push rods 21 are respectively horizontally slidably arranged in the central sliding grooves 16 of the three steel mounting frames 11. The first pushing device is transmission-connected to the three first linear push rods 21. The first hinged rod 22 and the horizontal sliding block 23 are each provided with a plurality of groups and correspond one-to-one to the plurality of groups of clamping assemblies. One end of the first hinged rod 22 is hinged to the side wall of the first linear push rod 21, and the other end of the first hinged rod 22 is hinged to the horizontal sliding block 23. The horizontal sliding block 23 is fixedly connected to the clamping plate 13. A horizontal sliding groove 24 for the horizontal sliding block 23 to slide is provided on the steel mounting frame 11. The length direction of the horizontal sliding groove 24 is perpendicular to the length direction of the I-beam 1. The steel mounting frame 11 is also provided with a first avoidance groove 25 for avoiding the first hinged rod 22.

[0041] The first pushing device includes a first linear drive 26, a split push plate 27, a first transmission plate 28, a telescopic rod 29 and a second spring 30. The first linear drive 26 is fixedly mounted on one of the rotating disks 10. The output end of the first linear drive 26 is fixedly connected to the first transmission plate 28. Three split push plates 27 are provided and are transmission-connected to three steel mounting frames 11. The split push plate 27 is slidably arranged on the first transmission plate 28. The split push plate 27 is fixedly connected to the corresponding first linear push rod 21. Three telescopic rods 29 and a second spring 30 are provided and are respectively arranged on the three steel mounting frames 11. One end of the telescopic rod 29 is fixedly connected to the first linear push rod 21, and the other end of the telescopic rod 29 is connected to one end of the flip plate close to the rotating disk 10. The second spring 30 is sleeved on the telescopic rod 29 and both ends of the second spring 30 are fixedly connected to both ends of the telescopic rod 29.

[0042] The first linear driver 26 drives the first transmission plate 28 to move, and then pushes the split push plate 27 to move through the first transmission plate 28. The arrangement of the split push plate 27 and the first transmission plate 28 can facilitate the first transmission plate 28 and the split push plate 27 to maintain a transmission relationship when the two steel mounting frames 11 are adjusted in spacing. The movement of the split push plate 27 drives the first linear push rod 21 fixedly connected thereto to slide in the central sliding groove 16 of the steel mounting frame 11. The sliding of the first linear push rod 21 drives the horizontal sliding block 23 to slide in the horizontal sliding groove 24 through the first hinged rod 22, thereby realizing the movement of the clamping plate 13 and completing the clamping action of the I-beam 1. The first linear driver 26 in the first pushing device drives the first transmission plate 28 to move, and through the coordinated action of the split push plate 27, the first linear push rod 21, the first hinged rod 22 and the horizontal sliding block 23, the clamping drive function is realized, thereby accurately clamping the I-beam 1. At the same time, the telescopic rod 29 and the second spring 30 play a role of buffering and resetting, ensuring the stability and reliability of the clamping action.

[0043] By centrally driving multiple first linear push rods 21 through the first push device, the synchronization and consistency of the clamping action are achieved, and the I-beam 1 can be clamped more efficiently. The transmission coordination between the various components is precise, which can ensure the uniform distribution of the clamping force, further improve the clamping stability of the I-beam 1, thereby ensuring the accuracy of the position of the I-beam 1 during the welding process and improving the welding quality. Moreover, the setting of the telescopic rod 29 and the second spring 30 enables the clamping action to have a certain elastic buffer, avoiding damage to the I-beam 1 due to excessive clamping force. This structure is compact, easy to maintain and control, can adapt to the needs of clamping the I-beam 1 under different working conditions, and enhances the versatility and reliability of the device.

[0044] The rotary drive assembly includes a first rotary driver 31, a driving shaft 32, a transmission mounting frame 33, a driving bevel gear 34, a driven bevel gear 35 and a driven threaded rod 36. The first rotary driver 31 is fixedly mounted on the rotating disk 10. The driving shaft 32 is coaxially arranged on the rotating disk 10. The output end of the first rotary driver 31 is fixedly connected to the driving shaft 32. The transmission mounting frame 33, the driving bevel gear 34, the driven bevel gear 35 and the driven threaded rod 36 are each provided with a plurality of threaded sliding seats 12 and the driven threaded rod 36. The threaded sliding seats 12 correspond to the driven threaded rod 36 one by one. The sliding seat 12 is threadedly connected to the driven threaded rod 36, the transmission mounting frame 33 is fixedly mounted on the steel mounting frame 11, the driving shaft 32 is rotatably set on the transmission mounting frame 33, the driving bevel gear 34 is fixedly connected to the driving shaft 32, the axial direction of the driven threaded rod 36 is perpendicular to the axial direction of the driving shaft 32, and the driven threaded rods 36 are symmetrically arranged along the vertical plane of the steel mounting frame 11 at the center, the driven bevel gear 35 is rotatably mounted on the transmission mounting frame 33, and the driven bevel gear 35 is fixedly mounted on the end of the driven threaded rod 36.

[0045] When the rotary drive assembly is working, the first rotary driver 31 drives the driving shaft 32 to rotate, and the driving bevel gear 34 on the driving shaft 32 rotates accordingly. The rotation of the driving bevel gear 34 drives the driven bevel gear 35 meshing therewith to rotate, thereby rotating the driven threaded rod 36. The rotation of the driven threaded rod 36 drives the threaded sliding seat 12 threadedly connected therewith to move, thereby realizing the spacing adjustment of the steel mounting frame 11. The two driven bevel gears 35 mesh with the same driving bevel gear 34, and the two driven bevel gears 35 are coaxial. At this time, when the driving bevel gear 34 rotates, the two driven bevel gears 35 rotate in opposite directions, thereby driving the two driven threaded rods 36 connected therewith to rotate in opposite directions, so that the threaded sliding seat 12 threaded therewith moves in opposite directions, thereby realizing the spacing adjustment function. It can adapt to the welding requirements of the bracket body 3 of different sizes, and improves the versatility and flexibility of the device. The transmission process is stable and reliable, with high precision, which ensures the fitting accuracy of the steel beam 2 and the end of the I-beam 1 during welding, thereby improving the welding quality. At the same time, this transmission structure is compact, occupies little space, and is easy to install and maintain.

[0046] The spacing adjustment mechanism 7 also includes a synchronous fixing column 37, a horizontal limit frame 38 and a transmission seat 39. Each steel mounting frame 11 is provided with a synchronous fixing column 37 on both sides along its length direction. The horizontal limit frame 38 is fixedly installed on both sides of the flip frame 5. The length direction of the horizontal limit frame 38 is consistent with the length direction of the steel beam 2. The end of the synchronous fixing column 37 is slidably set on the horizontal limit frame 38. The transmission seat 39 is slidably set on the synchronous fixing column 37 along the length direction of the synchronous fixing column 37. The transmission seat 39 is transmission-connected to the pushing mechanism 9.

[0047] The synchronous fixing column 37 slides on the horizontal limit frame 38 as the steel mounting frame 11 moves, playing a guiding and limiting role. The transmission seat 39 slides along the synchronous fixing column 37 and is connected to the pushing mechanism 9 in transmission, so as to achieve the coordination of the pushing action and the spacing adjustment. The cooperation between the synchronous fixing column 37 and the horizontal limit frame 38 ensures the stability and linearity of the spacing adjustment of the steel mounting frame 11, and avoids deviation and shaking during the adjustment process. The sliding transmission of the transmission seat 39 enables the pushing mechanism 9 to accurately push the steel beam 2 to the I-beam 1, thereby improving the accuracy and efficiency of welding. This structure is simple and reliable, easy to maintain, can adapt to frequent spacing adjustment operations, and enhances the durability and stability of the device.

[0048] The pushing mechanism 9 includes a pushing plate 40, a second linear driver 41, a second linear pushing rod 42, a linear pushing frame 43, a vertical baffle 44, a first limit baffle 45, a second limit baffle 46, a V-shaped contraction baffle 47, a horizontal pressure plate 48, a third spring 49, a vertical slide bar 50, a second hinged rod 51, a third hinged rod 52, a first hinged column 53, a second hinged column 54 and a retraction baffle 55. The second linear driver 41 is fixedly mounted on the rotating disk 10, and the pushing plate 40 is horizontally arranged on the flip frame 5. The length direction of the pushing plate 40 is consistent with the length direction of the steel beam 2, and the displacement direction of the pushing plate 40 is consistent with the length direction of the I-beam 1. The transmission seat 39 is slidably connected to the pushing plate 40, and the sliding direction of the transmission seat 39 is consistent with the length direction of the steel beam 2. The first limit baffle 45 is fixedly mounted on the top of the linear pushing frame 43, and the linear pushing frame 43 and the pushing plate 40 are connected. Sliding connection, second limit plates that limit the sliding of the linear pushing frame 43 are installed on both sides of the top of the pushing plate 40, the output end of the second linear driver 41 is fixedly connected to the second linear pushing rod 42, one end of the second linear pushing rod 42 is hinged to the second hinged rod 51, the other end of the second linear pushing rod 42 is hinged to the third hinged rod 52 through the first hinge column 53, the other end of the third hinged rod 52 is fixedly connected to the second hinge column 54, the second hinge column 54 is fixedly connected to the retraction baffle 55, the horizontal pressure plate 48 is horizontally arranged between the pushing plate 40 and the linear pushing frame 43, the horizontal pressure plate 48 and the linear pushing frame 43 are slidably connected through the vertical sliding rod 50, the third spring 49 is sleeved on the vertical sliding rod 50, the two ends of the third spring 49 are respectively fixedly connected to the horizontal pressure plate 48 and the linear pushing frame 43, and the V-shaped contraction baffle 47 is fixedly installed on the side of the flip frame 5 close to the rotating disk 10.

[0049] In the first step, the steel beam 2 is inserted from the side of the frame 4 and placed on the push plate 40 stably. In the second step, before pushing forward, it is retracted backward. This action drives the retraction baffle 55 to flip 90 degrees, against the side wall of the steel beam 2, and prompts the steel beam 2 to retreat. In this process, the two ends of the steel beam 2 will be limited by the symmetrically arranged V-shaped shrink baffles 47, thereby realizing the automatic centering process of the steel beam 2. Moreover, since the steel beam 2 is not clamped at this time, the steel beam 2 can be longitudinally displaced to automatically complete the deviation correction and centering operation. In the third step, it starts to push forward. The push plate 40 is driven by the second limit baffle 46 and moves synchronously with the linear push frame 43. At this time, the second linear push rod 42 drives the second hinged rod 51 and the third hinged rod 52 to deflect. When the third hinged rod 52 deflects, it drives the second hinged column 54 fixedly connected thereto to deflect synchronously, so that the retraction baffle 55 flips 90 degrees to ensure that it is in a horizontal state, which is convenient for subsequent welding and blanking operations. At the same time, the first hinged column 53 is displaced downward under the action of the second hinged rod 51 and the third hinged rod 52, and contacts the horizontal pressure plate 48, so that the horizontal pressure plate 48 overcomes the elastic force of the third spring 49 and displaces downward, and the steel beam 2 under the horizontal pressure plate 48 is firmly pressed against the pushing plate 40, thereby realizing the clamping function and providing stable conditions for subsequent welding work.

[0050] This transmission design makes the pushing mechanism 9 move coherently and accurately. Through the coordinated action of various components, such as the second linear drive 41, the linear pushing frame 43, the retracting baffle 55, the horizontal pressing plate 48, etc., a series of actions such as accurate pushing, centering, and clamping of the steel beam 2 are achieved. The flip design of the retracting baffle 55 not only achieves the centering of the steel beam 2 but also does not affect the subsequent horizontal placement. The cooperation between the horizontal pressing plate 48 and the spring provides a reliable clamping force when clamping is required, and has a certain flexibility when clamping is not required.

[0051] This carefully designed step-by-step pushing and center clamping method greatly improves the automatic centering and deviation correction capabilities of the steel beam 2 during the pushing process, significantly enhances the accuracy of the docking between the steel beam 2 and the I-beam 1 before welding, and effectively improves the welding quality. The clever coordination of the retraction baffle 55 and the V-shaped shrinkage baffle 47 successfully realizes the efficient automatic positioning of the steel beam 2, greatly reduces the tedious steps of manual adjustment, and effectively improves work efficiency. The clamping function of the horizontal pressure plate 48 effectively ensures the stability of the steel beam 2 during welding, avoids possible displacement during the welding process, and further ensures high-quality welding results. The entire process shows a high level of automation, with simple and smooth operation, which greatly improves the practical value and operational reliability of the device.

[0052] A plurality of evenly distributed supporting and abutting balls 56 are disposed on the surface of the steel material mounting frame 11 .

[0053] The design of the supporting and resisting balls 56 can ensure that the I-beam 1 can move and slide smoothly when it needs to be centered and corrected after being clamped.

[0054] The flipping mechanism 8 also includes a second rotation driver 57, a rotation support cylinder 58, a ring gear 59, a driving gear 60, a semi-arc sliding ring 61 and a limit fixing block 62. The second rotation driver 57 is fixedly mounted on the outer wall of the frame 4, the driving gear 60 is axially connected to the frame 4, the output end of the second rotation driver 57 is fixedly connected to the driving gear 60, the rotation support cylinder 58 is rotatably mounted on the frame 4, the rotation support cylinder 58 is coaxially arranged with the transmission shaft, the rotation support cylinder 58 is fixedly connected to the flipping frame 5, the ring gear 59 is fixedly mounted on the outer wall of the rotation support cylinder 58, the driving gear 60 is meshed with the ring gear 59, the semi-arc sliding ring 61 is fixedly connected to the flipping frame 5, the limit fixing block 62 is fixedly mounted on the frame 4, and the flipping frame 5 is slidably connected to the frame 4 via the semi-arc sliding ring 61 and the limit fixing block 62.

[0055] The second rotary driver 57 drives the driving gear 60 to rotate, and the ring gear 59 meshing with the driving gear 60 drives the rotating support cylinder 58 to rotate, so that the turning frame 5 fixedly connected to the rotating support cylinder 58 can turn over. The semi-arc sliding ring 61, under the restriction of the limit fixing block 62, ensures that the turning frame 5 turns over smoothly and accurately.

It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
