Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to an automatic welding device for H-shaped steel. Background Art

[0002] H-shaped steel is an economical and efficient profile with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the English letter "H". Since all parts of H-shaped steel are arranged at right angles, H-shaped steel has the advantages of strong bending resistance, simple construction, cost saving and light structure weight in all directions. It has been widely used. Welding: also known as fusion welding, melting welding, is a manufacturing process and technology for joining metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. Welding achieves the purpose of joining through the following three ways: fusion welding, pressure welding and brazing. There are many sources of energy for modern welding, including gas flame, arc, laser, electron beam, friction and ultrasonic. The existing steel welding is generally manual welding or welding by machine in the factory. H-shaped steel has a complex shape. It is generally manual welding when welding outside. Long-term welding is more laborious and troublesome. Workers are tired after long-term work, which will make manual welding unstable, thus affecting the welding quality.

[0003] The prior art, such as announcement number CN219402948U, provides an automatic welding device for H-beam production, including a telescopic bracket, wherein the bottom of the telescopic bracket is respectively connected to a support rod and a suspension rod, the bottom end of the support plate is connected to a mounting plate, the bottom of the mounting rod is connected to a roller through a directional bracket, the bottom end of the suspension rod is connected to a cross bar, the bottom of one end of the cross bar is connected to a welding gun through an adjusting bracket, the bottom of the other end of the cross bar is connected to a rotating motor through a connecting rod, and the bottom of the rotating motor is connected to a traction power wheel through a rotating shaft. The utility model has a simple structure and is easy to use. It can automatically adapt to the size of the H-beam after adjustment, and can move on the H-beam to perform welding operations. It has a small size, strong practicality, and low cost. The symmetrically arranged structure can ensure higher stability during welding, and welding processing can be performed on both sides of the H-beam at the same time, which greatly improves the processing efficiency.

[0004] In this solution, the telescopic bracket is stretched to both sides and automatically retracted inward after stretching, so that the traction power wheel can fit tightly on the two side surfaces of the H-beam, and the device is placed on the H-beam with the support rod, and then the traction power wheel is used to drive the device to move on the H-beam. However, during the storage and transportation of steel, if the steel is subjected to external forces such as collision and extrusion, the surface may become uneven. For example, during the loading and unloading process, collisions between steels or collisions with other hard objects may cause the H-beam to become concave or convex, which may cause the welding gun to shake when the power wheel rolls on the surface of the steel, thereby affecting the welding quality. In view of this, we propose an automatic welding device for H-beams. Utility Model Content

[0005] The utility model aims to provide an automatic welding device for H-shaped steel, which solves the problem that the welding quality is affected by the insufficient stability of the welding gun.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] An automatic welding device for H-shaped steel comprises a steel material, a welding mechanism is arranged inside the steel material, and an adjustment mechanism is arranged on the top of the steel material;

[0008] The welding mechanism includes two support plates, which are arranged on both sides of the steel material, and the support plates are fixedly connected to two bonding plates through right-angle brackets. An inclined plate is arranged between the bonding plates, and the two ends of the inclined plate are respectively slidably connected to the slideways opened on the corresponding bonding plates. The inner wall of the inclined plate is fixedly connected to an electric telescopic rod, and the telescopic end of the electric telescopic rod is fixedly connected to a welding gun.

[0009] Preferably, the two bonding plates on the right-angle bracket are vertical, and the angles between the two bonding plates and the welding gun are consistent.

[0010] Preferably, a plurality of groups of balls are fixedly connected to one side of the bonding plate corresponding to the steel material and are evenly distributed on the surface of the bonding plate.

[0011] Preferably, a lead screw is rotatably connected to the position between the right-angle brackets at both ends of the support plate, a sleeve is threadedly connected to the outer wall of the lead screw, and the sleeve is fixedly connected to the inclined plate, and a first servo motor for driving the lead screw to rotate is fixedly connected to the right-angle bracket.

[0012] Preferably, the adjustment mechanism includes a support frame, which is placed on the top of the steel material, and slides are slidably connected to both sides of the inner wall of the support frame through limit grooves, and multiple sliding rods are slidably connected to the inner walls of the two slides, and the sliding rods are fixedly connected to the support plates at corresponding positions.

[0013] Preferably, the slide bars are evenly distributed on the inner wall of the slide plate, and a stopper is fixedly connected to the top of the slide bar.

[0014] Preferably, the inner wall of the support frame is rotatably connected to a bidirectional threaded rod, and the outer wall of the support frame is fixedly connected to a second servo motor for driving the bidirectional threaded rod to rotate. The bidirectional threaded rod is driven to rotate by starting the second servo motor, and is relatively limited with the slide plate through a limiting groove. When the bidirectional threaded rod rotates, the support plate is driven to unfold.

[0015] By means of the above technical solution, the utility model provides an automatic welding device for H-beams, which has at least the following beneficial effects:

[0016] 1. The utility model uses two bonding plates to press against the inner wall of the steel material, so that the bonding plates and the steel material are always in a parallel state, thereby ensuring the stability of the welding gun during welding and avoiding the problem of the welding effect being affected by the shaking of the welding gun in the comparative solution.

[0017] 2. When welding is required, the utility model places the support frame on the top of the steel material. Since the support plate is slidably connected to the slide plate by a sliding rod, the support plate will automatically sink due to its own gravity when the support frame is placed. At this time, the second servo motor is started to drive the two-way threaded rod to rotate, and the limit groove and the slide plate are relatively limited, so that when the two-way threaded rod rotates, the support plate can be driven to unfold, so that the fitting plates on both sides of the support plate are against the inner wall of the steel material, so as to facilitate the positioning of the welding position and to adapt to steel materials of different sizes.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] An automatic welding device for H-beam, such as Figure 1 - Figure 4 As shown, it includes a steel material 1, a welding mechanism 2 is arranged inside the steel material 1, an adjusting mechanism 3 is arranged on the top of the steel material 1, the welding mechanism 2 includes two support plates 21, the two support plates 21 are arranged on both sides inside the steel material 1, and the support plates 21 are fixedly connected with two bonding plates 23 through right-angle brackets 22, an inclined plate 26 is arranged between the bonding plates 23, and the two ends of the inclined plate 26 are respectively slidably connected with the slideways 25 opened on the corresponding bonding plates 23, an electric telescopic rod 27 is fixedly connected to the inner wall of the inclined plate 26, and a welding gun 28 is fixedly connected to the telescopic end of the electric telescopic rod 27, the two bonding plates 23 on the right-angle bracket 22 are in a vertical position relationship, and the angles between the two bonding plates 23 and the welding gun 28 are consistent, and a plurality of groups of balls 24 are fixedly connected to one side of the bonding plate 23 corresponding to the steel material 1, and are evenly distributed on the surface of the bonding plate 23.

[0027] In this embodiment, two bonding plates 23 are pressed against the inner wall of the steel material 1 so that the bonding plates 23 and the steel material 1 are always in a parallel state, thereby ensuring the stability of the welding gun 28 during welding and avoiding the problem of the welding effect being affected by the shaking of the welding gun 28 in the comparative solution.

[0028] Example 2

[0029] like Figure 3 , Figure 4As shown, a lead screw 29 is rotatably connected to the position between the right-angle brackets 22 at both ends of the support plate 21, a sleeve 291 is threadedly connected to the outer wall of the lead screw 29, and the sleeve 291 is fixedly connected to the inclined plate 26, and a first servo motor 292 for driving the lead screw 29 to rotate is fixedly connected to the right-angle bracket 22.

[0030] In this embodiment, the first servo motor 292 is started to drive the screw 29 to rotate, and relative limiting is performed through the limiting relationship between the inclined plate 26 and the slide 25, so that when the screw 29 rotates, it will drive the inclined plate 26 connected to the sliding sleeve 291 to slide in the slide 25, so as to facilitate the welding gun 28 to weld the joint at a uniform speed.

[0031] Example 3

[0032] like Figure 1 , Figure 2 As shown, the adjustment mechanism 3 includes a support frame 31, which is placed on the top of the steel material 1. Both sides of the inner wall of the support frame 31 are slidably connected with slide plates 35 through limit grooves 33. The inner walls of the two slide plates 35 are slidably connected with multiple slide rods 36, and the slide rods 36 are fixedly connected to the support plates 21 at corresponding positions. The slide rods 36 are evenly distributed on the inner walls of the slide plates 35. A stopper 37 is fixedly connected to the top of the slide rods 36. The inner wall of the support frame 31 is rotatably connected with a bidirectional threaded rod 32, and the outer wall of the support frame 31 is fixedly connected with a second servo motor 34 for driving the bidirectional threaded rod 32 to rotate.

[0033] In this embodiment, when welding is required, the support frame 31 is placed on the top of the steel 1. Since the support plate 21 is slidably connected to the slide plate 35 by the slide rod 36, the support plate 21 will automatically sink due to its own gravity when the support frame 31 is placed. At this time, the second servo motor 34 is started to drive the bidirectional threaded rod 32 to rotate, and the limit groove 33 and the slide plate 35 are relatively limited, so that when the bidirectional threaded rod 32 rotates, it can drive the support plate 21 to unfold, so that the bonding plates 23 on both sides of the support plate 21 are against the inner wall of the steel 1, so as to facilitate the positioning of the welding position, so as to facilitate the adaptation to steels 1 of different sizes.

[0034] When the automatic welding device for H-shaped steel of the utility model is in use, the support frame 31 is placed on the top of the steel material 1. Since the support plate 21 is slidably connected to the slide plate 35 by the sliding rod 36, the support plate 21 will automatically sink due to its own gravity when the support frame 31 is placed. At this time, the two-way threaded rod 32 is driven to rotate by starting the second servo motor 34, and the limit groove 33 and the slide plate 35 are relatively limited. When the two-way threaded rod 32 rotates, the support plate 21 can be driven to expand, so that the bonding plates 23 on both sides of the support plate 21 are against the inner wall of the steel material 1, so as to facilitate the positioning of the welding position, and then the first servo motor 292 is started to drive the lead screw 29 to rotate, and the inclined plate 26 and the slideway 25 are relatively limited by the limiting relationship, so that when the lead screw 29 rotates, the inclined plate 26 connected to the sliding sleeve 291 is driven to slide in the slideway 25, so as to facilitate the welding gun 28 to weld the joint seam at a uniform speed.
