Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a welding device for an assembling machine and an assembling machine. Background Art

[0002] The production process of H-beam includes cutting, assembly, correction, shot blasting and other processes. Among them, the assembly process needs to be realized with the help of H-beam automatic assembly machine.

[0003] The working principle of the H-beam automatic assembly machine is as follows: First, the cutting machine unloads the material and hoists the flattened steel plates (upper wing plate, lower wing plate, and web plate) onto the input roller of the assembly machine. After that, the three sets of clamping devices of the assembly machine initially clamp and position the upper wing plate, lower wing plate, and web plate. Next, the input roller inputs the workpiece into the main machine, and the main machine adjusts the reference dimensions of the upper wing plate, lower wing plate, and web plate, accurately positions and centers the workpiece, and then performs positioning spot welding. After that, the spot-welded H-beam is removed from the assembly machine by a crane and enters the next process.

[0004] However, in the automatic assembly machine for H-beams, the relevant automatic spot welding device is fixed on the machine base of the assembly machine and cannot move along the assembly direction. When spot welding the workpiece, it is necessary to stop after assembling the workpiece for a period of time, complete the spot welding action of the workpiece through the automatic spot welding device, and then continue to assemble. In this welding method, in order to realize the assembly of H-beams, multiple pauses are required to complete the spot welding action, which wastes time and seriously reduces the assembly efficiency of H-beams.

[0027] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are 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.

[0028] In one embodiment of the present invention, a welding device for an assembly machine and an assembly machine are provided. The welding device can be installed on the assembly machine. During the welding process of the workpiece, the welding assembly in the welding device can move synchronously with the workpiece, and the spot welding action can be completed without stopping the workpiece, which can improve production efficiency. Figure 1 and Figure 2 The welding device for an assembling machine and the assembling machine in this embodiment are further described.

[0029] Specifically, if Figure 1 and Figure 2As shown, the welding device for the assembly machine in this embodiment includes: a first moving component 1, a second moving component 2 and a welding component 3.

[0030] Among them, the first movable component 1 is used to be installed to the assembly machine; the second movable component 2 is connected to the first movable component 1, and the first movable component 1 can drive the second movable component 2 to move along the first direction; the welding component 3 is used to weld the workpiece, the welding component 3 is connected to the second movable component 2, and the second movable component 2 can drive the welding component 3 to move along the second direction, and the second direction is perpendicular to the first direction.

[0031] Exemplarily, the first movable component 1 can be installed on the assembly machine with the aid of bolts and other structures, and can be fixed to the side of the workpiece, while making the first direction the moving direction for assembling the workpiece, and the second direction being the direction perpendicular to the workpiece assembly. Thus, the first movable component 1 can drive the second movable component 2 to move along the direction of workpiece assembly, and the second movable component 2 can drive the welding component 3 to move toward the direction where the workpiece is located.

[0032] In actual production, when H-shaped steel needs to be welded, the relevant workpiece can be placed on the assembly machine, and the rollers on the assembly machine will drive the workpiece to move along the assembly direction. During its movement, for the welding device, the second moving component 2 will drive the welding component 3 to move toward the workpiece, so that the welding component 3 can contact the workpiece and weld it. At the same time, the first moving component 1 can drive the second moving component 2 to move synchronously with the workpiece along the assembly direction, so that the welding component 3 has sufficient contact time to weld the workpiece.

[0033] Therefore, with the help of the welding device in this embodiment, when the H-beam workpiece is welded on the assembly machine, the workpiece does not need to stop and can maintain the assembly working state, which can save waiting time and improve the assembly production efficiency.

[0034] In one embodiment, Figure 1 and Figure 2 As shown, the first moving assembly 1 may include: a first mounting seat 11 , a first sliding seat 12 , a first screw rod and a first driving motor 13 .

[0035] Among them, the first slide 12 is arranged on the first mounting seat 11, the first screw rod extends along the first direction and is rotatably arranged on the first mounting seat 11, the first slide 12 is threadedly connected to the first screw rod, the first drive motor 13 is arranged on the first mounting seat 11 and can drive the first screw rod to rotate, and the second moving component 2 is connected to the first slide 12.

[0036] Specifically, the first mounting seat 11 can be made of metal material, and the first mounting seat 11 can be fixedly mounted on the assembly machine by means of bolts and other structures. The first mounting seat 11 has a track extending along the first direction, and the first slide 12 is arranged in the track of the first mounting seat 11. After the welding device is fixedly mounted on the assembly machine, the first slide 12 can move along the assembly direction of the workpiece in the track.

[0037] As an implementation method, the first mounting seat 11 includes two parallel and spaced limiting plates, a track extending along the first direction is formed between the two limiting plates, and the first slide seat 12 is arranged between the two limiting plates, and the two ends of the first slide seat 12 are respectively abutted against the two limiting blocks. Thus, the first slide seat 12 can move along the first direction on the first mounting seat 11.

[0038] The first screw rod is extended along the first direction, the first slide seat 12 is provided with a threaded hole, the first screw rod is threadedly connected to the threaded hole of the first slide seat 12, and the first drive motor 13 is connected to the first screw rod and can drive the first screw rod to rotate.

[0039] In actual use, the first drive motor 13 can be connected to the control device of the assembly machine by signal. In the process of driving the roller of the assembly machine to rotate, the control device can send a control signal to the first drive motor 13, so that the first drive motor 13 drives the first screw to rotate, so that the first slide 12 can move synchronously with the workpiece on the roller, thereby ensuring that the second moving component 2 and the welding component 3 can move synchronously with the workpiece.

[0040] In one embodiment, Figure 1 and Figure 2 As shown, the second moving assembly 2 includes: a second mounting seat 21 , a second sliding seat 22 and a driving cylinder 23 .

The output end of the driving cylinder 23 is connected to the second slide 22, and the driving cylinder 23 can drive the second slide 22 to move back and forth in the second direction.

[0043] In actual use, after the workpiece is placed on the roller of the assembly machine, the driving cylinder 23 in the second moving assembly 2 can drive the second slide 22 to move toward the workpiece, so that the welding assembly 3 can reach the welding point, thereby ensuring that the welding assembly 3 can perform welding processing on the workpiece. Moreover, in the process of the roller of the assembly machine driving the workpiece to move, the first moving assembly 1 can drive the second moving assembly 2 to move synchronously with the workpiece, so that the welding assembly 3 can also move synchronously with the workpiece, thereby ensuring that the welding assembly 3 can continue to weld the workpiece. After the welding process is completed, the driving cylinder 23 in the second moving assembly 2 can drive the second slide 22 away from the workpiece, so that the welding assembly 3 can leave the welding point in time, and then the first moving assembly 1 drives the second moving assembly 2 back to the initial position, so as to facilitate the subsequent welding process of other welding points of the workpiece.

[0044] Furthermore, in order to avoid positional deviation of the second slide 22 during movement and ensure welding accuracy, Figure 1 and Figure 2 As shown, a slide groove is provided at the bottom of the second slide seat 22 , and a slide rail 24 extending along the second direction is provided at the second mounting seat 21 . The slide groove can move along the extending direction of the slide rail 24 .

[0045] Exemplarily, the slide rail 24 on the second mounting seat 21 can be constructed as a flange structure protruding outward and extending along the second direction, and the slide groove at the bottom of the second slide seat 22 can be a groove structure recessed inward and extending along the second direction. The slide rail 24 is clamped in the slide groove, and the cross-section of the slide groove is adapted to the cross-section of the slide rail.

[0046] Therefore, in actual use, when the driving cylinder 23 drives the second slide 22 to move, the second slide 22 can move along the extension direction of the slide rail 24 without positional deviation.

[0047] Further, in order to achieve effective installation, in a specific embodiment, as Figure 1 and Figure 2 As shown, the second mounting base 21 includes a mounting bracket 25, a horizontal plate 26 and a vertical plate 27.

[0048] Exemplarily, the mounting bracket 25 can be fixedly connected to the first slide 12 of the first moving assembly 1 by means of bolts or other structures, the horizontal plate 26 is fixedly connected to the mounting bracket 25, the length direction of the horizontal plate 26 is extended along the second direction, the slide rail 24 for limiting the movement of the second slide 22 is arranged on the horizontal plate 26, and the second slide 22 is slidably connected to the horizontal plate 26. The vertical plate 27 is fixedly connected to one end of the horizontal plate 26 in the length direction close to the first moving assembly 1, the driving cylinder 23 is connected to the side of the vertical plate 27 away from the second slide 22, and the output end of the driving cylinder 23 is connected to the second slide 22 through the vertical plate 27.

[0049] Furthermore, in this embodiment, the welding assembly 3 includes: a first adjusting mechanism 31, a second adjusting mechanism 32 and a welding mechanism 33, the first adjusting mechanism 31 is connected to the second movable assembly 2, the second adjusting mechanism 32 is connected to the first adjusting mechanism 31, the welding mechanism 33 is arranged on the second adjusting mechanism 32, the first adjusting mechanism 31 can adjust the position of the second adjusting mechanism 32 in the third direction, the second adjusting mechanism 32 can adjust the position of the welding mechanism 33 in the fourth direction, and the third direction and the fourth direction are perpendicular to each other.

[0050] Exemplarily, the third direction and the fourth direction are both perpendicular to the first direction, that is, the plane where the third direction and the fourth direction are located is perpendicular to the first direction.

[0051] In the present embodiment, the welding mechanism 33 can perform welding processing on the workpiece.

[0052] It can be understood that in the actual production process, H-beams of different sizes may be welded on the assembly machine. H-beams of different sizes have different welding points. In order to achieve welding of H-beams of various sizes, in this embodiment, after the welding device is fixedly installed on the assembly machine, the position of the welding mechanism 33 relative to the workpiece can be adjusted in advance according to the welding requirements through the first adjustment mechanism 31 and the second adjustment mechanism 32.

[0053] In this embodiment, a worker can manually adjust the position of the welding mechanism 33 through the first adjustment mechanism 31 and the second adjustment mechanism 32 .

[0054] To achieve manual adjustment, in one embodiment, Figure 1 and Figure 2 As shown, the first adjustment mechanism 31 may include: a first fixing seat, a first screw rod, a first support rod, a first adjustment seat and a first rotating disk 34 .

[0055] Among them, the first fixed seat is fixedly connected to the second moving component, the first screw is rotatably arranged on the first fixed seat, the first support rod is arranged in parallel and spaced apart on the side of the first screw and fixed on the first fixed seat, the first turntable 34 is fixedly connected to the first screw, the first adjustment seat has a first threaded hole and a first positioning hole, the first screw is threadedly connected to the first threaded hole, the first support rod is inserted in the first positioning hole, and the second adjustment mechanism 32 is connected to the first adjustment seat.

[0056] Specifically, the first fixed seat can be fixedly connected to the second slide seat 22 of the second moving assembly 2 by means of bolts or other structures. For example, the first fixed seat can be fixedly connected to the second slide seat 22 by means of a right-angle plate.

[0057] The first screw extends along the third direction and is rotatably arranged on the first fixing seat. The first support rod extends along the third direction and is arranged on the side of the first screw. For example, there may be two first support rods, which are respectively arranged on both sides of the first screw.

[0058] The first screw rod is threadedly connected to the first threaded hole of the first adjustment seat, the first support rod is inserted into the first positioning hole of the first adjustment seat, and the first rotating disk 34 is connected to the end of the first screw rod.

[0059] Therefore, when the first turntable 34 drives the first screw to rotate, the first adjustment seat can be moved along the length direction of the first screw, and the second adjustment mechanism 32 can also be moved along the third direction.

[0060] Similarly, if Figure 1 and Figure 2 As shown, the second adjustment mechanism 32 includes: a second fixing seat, a second screw rod, a second support rod, a second adjustment seat and a second turntable 35 .

In the process of the second turntable 35 driving the second screw rod to rotate, the second adjustment seat can be moved along the length direction of the second screw rod, and the welding mechanism 33 can also be moved along the fourth direction at this time.

[0063] Therefore, after the first moving assembly 1 is fixedly mounted on the assembly machine, the position of the welding mechanism 33 can be manually adjusted with the help of the first turntable 34 and the second turntable 35, so that the welding mechanism 33 can reach the welding position more accurately.

[0064] Furthermore, if Figure 1 and Figure 2 As shown, the welding mechanism 33 includes a welding chuck 36 and a welding gun 37 . The welding chuck 36 is fixedly disposed on the second adjustment mechanism 32 , and the welding gun 37 is fixed on the welding chuck 36 .

[0065] As an implementation method, one end of the welding chuck 36 is configured as a stud, which can pass through the second adjustment seat of the second adjustment mechanism 32 and be threadedly connected to the nut, thereby, the welding chuck 36 can be fixed to the second adjustment seat by means of the nut.
