Description

Technical Field

[0001] This utility model relates to the field of H-beam processing technology, specifically to an automatic spot welding H-beam assembly machine. Background Technology

[0002] H-beams are steel beams with an H-shaped cross-section, possessing advantages such as bending resistance and high strength. They are used for load-bearing in buildings. H-beams consist of two parts: a central web and two side flanges. They are produced by welding the web and side flanges together. An assembly machine is a common steel structure processing equipment, mainly used to assist in the welding of steel components. When welding H-beams, the web and flanges need to be assembled. Transmission rollers are used to drive the horizontal plates, and cylinder assemblies are used to press and stabilize the vertical plates. Finally, manual welding is performed.

[0003] In the prior art, such as the H-beam assembly machine in patent number CN221047688U, there is a drive box. A worktable is provided on the upper surface of the drive box. Mounting frames are provided on both sides above the worktable. A positioning component is provided inside the mounting frame. The positioning component includes a rotating wheel set inside the mounting frame. A driven gear is provided on the outer surface of the rotating wheel. A positioning groove is opened in the center of the rotating wheel. Telescopic push rods are provided on the inner walls of the positioning groove. A clamping plate is provided at the output end of the telescopic push rod. A drive frame is provided on one side of the mounting frame. A motor is provided on one side of the drive frame. A drive gear is provided at the output end of the motor. The drive gear is set inside the drive frame and meshes with the driven gear.

[0004] While the aforementioned patent can fix and clamp H-beams, some problems still exist. Using multiple clamping plates to fix and clamp the H-beams makes it difficult to move them, thus requiring multiple repositioning of the welding position, which undoubtedly increases the difficulty of welding the H-beams. At the same time, using clamping plates makes it difficult to align the multiple steel plates on the H-beams, which may affect the welding effect. Therefore, this utility model provides an automatic spot welding H-beam assembly machine. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an automatic spot welding H-beam assembly machine. It solves the problem that using multiple clamping plates to fix and hold H-beams makes it difficult to move them, thus requiring multiple repositioning of the welding position, which undoubtedly increases the difficulty of welding H-beams.

[0008] The limiting assembly includes two sliding mounting plates and two horizontal plates. A set of limiting rollers is rotatably mounted on the top of the sliding mounting plates. A set of connecting rods is fixedly mounted on the outer wall of the horizontal plates. A C-shaped plate is fixedly mounted on one end of the outer wall of the connecting rods.

[0014] Beneficial effects

[0015] This utility model provides an automatic spot welding H-beam assembly machine. Compared with the prior art, it has the following advantages:

[0016] 1. This automatic spot welding H-beam assembly machine places the H-beam on top of the bottom conveyor roller. Then, a first electric push rod drives the upper conveyor roller downwards until a certain pressure is applied to the upper steel plate, allowing the steel plates on the H-beam to fit tightly together. At this point, the first motor starts, driving a rotating rod to rotate. The sliding strip on the rotating rod engages with a sliding bevel gear, causing the sliding bevel gear to rotate. Simultaneously, the rotating rod also causes a second bevel gear to rotate, thus enabling the two first bevel gears to mesh and drive each other. Through the transmission of the sprocket and chain assembly, the upper and lower sets of conveyor rollers can rotate in opposite directions, achieving the conveying of the H-beam. Therefore, it eliminates the need for multiple movements of the welding position; only the position of the H-beam needs to be moved to complete the welding, reducing the welding difficulty and improving welding efficiency.

[0017] 2. This automatic spot welding H-beam assembly machine uses a second motor to drive a bidirectional screw, which is threadedly connected to two sliding mounting plates. This allows the two sliding mounting plates to move towards or away from each other, driving the limiting rollers to limit the two flanges of the H-beam. A second electric push rod pushes a horizontal plate, and the connecting rod and C-shaped plate on the horizontal plate drive the limiting wheel to move, limiting the web of the H-beam. This makes it easier to align the multiple steel plates on the H-beam, ensuring accurate positioning of each component, thus guaranteeing welding quality and improving the overall quality of the H-beam. Furthermore, because the limiting rollers and limiting wheels can rotate, the limiting action does not affect the movement of the H-beam on the conveyor rollers. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides two technical solutions:

[0027] Figures 1-6 The first embodiment is shown: an automatic spot welding H-beam assembly machine, including a mounting frame 1, a clamping and conveying assembly 3 is provided on the inner wall of the mounting frame 1, and limit components 4 are provided on both sides of the outer wall of the clamping and conveying assembly 3.

[0028] The clamping and conveying assembly 3 includes two mounting frames 31. A set of conveying rollers 32 are rotatably mounted on the inner wall of the mounting frame 31. One end of the outer wall of the set of conveying rollers 32 passes through the outer wall of the mounting frame 31 and is provided with a sprocket and chain assembly 33. The other end of the outer wall of one of the set of conveying rollers 32 passes through the outer wall of the mounting frame 31 and is fixedly mounted with a first bevel gear 34. The two first bevel gears 34 are respectively meshed with a second bevel gear 37 and a sliding bevel gear 38.

[0029] The limiting assembly 4 includes two sliding mounting plates 43 and two horizontal plates 46. A set of limiting rollers 44 are rotatably mounted on the top of the sliding mounting plate 43. A set of connecting rods 47 are fixedly mounted on the outer wall of the horizontal plate 46. A C-shaped plate 48 is fixedly mounted on one end of the outer wall of the connecting rod 47. A limiting wheel 49 is rotatably mounted on the inner wall of the C-shaped plate 48.

[0030] A rotating rod 35 is rotatably mounted on the inner wall of the mounting frame 1. Two slide bars 36 are fixedly mounted on the outer wall of the rotating rod 35. The rotating rod 35 and the two slide bars 36 are slidably connected to the sliding bevel gear 38, so that the sliding bevel gear 38 can slide on the surfaces of the rotating rod 35 and the slide bars 36. Due to the setting of the slide bars 36, when the rotating rod 35 rotates, it can drive the sliding bevel gear 38 to rotate together. A connecting plate 39 is rotatably mounted on the outer wall of the sliding bevel gear 38. The connecting plate 39 can drive the sliding bevel gear 38 to move. One side of the outer wall of the connecting plate 39 is fixedly connected to the mounting bracket 31. The second bevel gear 37 is fixedly connected to the rotating rod 35.

[0031] A first motor 310 is fixedly mounted on the top of the mounting frame 1. The output end of the first motor 310 passes through the inner wall of the mounting frame 1 and is fixedly connected to one end of the outer wall of the rotating rod 35. The first motor 310 can drive the rotating rod 35 to rotate. Figure 3 It can be seen that because the sliding bevel gear 38 and the second bevel gear 37 mesh with the two first bevel gears 34 in different ways, the two first bevel gears 34 will rotate in opposite directions. The top of the mounting frame 1 is fixedly mounted with a first electric push rod 2. One of the two mounting brackets 31 is fixedly connected to the output end of the first electric push rod 2. The first electric push rod 2 can drive the upper mounting bracket 31 to move, so that the upper conveying roller 32 can contact the steel plate. One of the two mounting brackets 31 is fixedly connected to the bottom of the inner wall of the mounting frame 1.

[0032] Figures 1-6 The second embodiment is shown. The main difference from the first embodiment is that the limiting component 4 also includes a housing 41. A bidirectional screw 42 is rotatably mounted on the inner wall of the housing 41. The outer wall of the bidirectional screw 42 is threadedly connected to two sliding mounting plates 43. The housing 41 is fixedly mounted in the inner wall of a mounting bracket 31.

[0033] A second motor 410 is fixedly mounted on the outer wall of one of the two mounting brackets 31. The output shaft of the second motor 410 passes through the inner wall of the housing 41 and is fixedly connected to one end of the outer wall of the bidirectional screw 42. Second electric push rods 45 are fixedly mounted on both sides of the inner wall of the mounting frame 1. The output shafts of the two second electric push rods 45 are fixedly connected to the two horizontal plates 46.

[0034] Welding devices 5 are fixedly installed on both sides of the inner wall of the mounting frame 1. The welding devices 5 are existing technology and are usually composed of an electric slide rail and a welding gun. The electric slide rail can drive the welding gun to move, so as to weld the gaps at different joints of the H-beam. A set of limiting rollers 44 are staggered with a set of conveying rollers 32 to avoid collision between the limiting rollers 44 and the conveying rollers 32 when they move. A set of limiting rollers 44 are staggered with a set of connecting rods 47 to avoid collision between the connecting rods 47 and the limiting rollers 44. One end of the outer wall of a set of conveying rollers 32 is connected by a sprocket and chain group 33. The sprocket and chain group 33 is existing technology and is composed of multiple sprockets and chains. When one conveying roller 32 rotates, the sprockets and chains can cooperate to make a set of conveying rollers 32 rotate simultaneously. Since the conveying rollers 32 can contact the steel plate, the rotation of the conveying rollers 32 can drive the steel plate to move.

[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0036] During operation, one flange of the H-beam is first placed on top of the bottom conveyor roller 32, and then the web is placed on top of this flange. At the same time, two second electric push rods 45 are activated, pushing the cross plate 46 to move. The connecting rod 47 and C-shaped plate 48 on the cross plate 46 drive the limiting wheel 49 to move, so that the limiting wheel 49 contacts the web surface, limiting the web of the H-beam. Then, another flange is placed on top of the web. At this time, the second motor 410 is activated, driving the bidirectional screw 42 to rotate. The bidirectional screw 42 is threadedly connected to two sliding mounting plates 43, making... The two sliding mounting plates 43 move towards or away from each other, driving the limiting rollers 44 to limit the two flanges of the H-beam, aligning them. The first electric push rod 2 then drives the upper conveying roller 32 downwards until a certain pressure is applied to the upper steel plate, ensuring the plates on the H-beam fit tightly together. At this point, the first motor 310 starts, driving the rotating rod 35 to rotate. The sliding strip 36 on the rotating rod 35 engages with the sliding bevel gear 38, causing the sliding bevel gear 38 to rotate. Simultaneously, the rotating rod 35 causes the second bevel gear 37 to rotate, thus meshing and transmitting power between the two first bevel gears 34. Through the transmission of the sprocket and chain assembly 33, the upper and lower conveying rollers 32 can rotate in opposite directions, achieving the conveying of the H-beam. This eliminates the need for multiple movements of the welding position; only the position of the H-beam needs to be moved to complete the welding, reducing the welding difficulty and improving efficiency. When the H-beam reaches the welding device 5, the joints can be welded.
