Description

Technical Field

[0001] This utility model relates to the field of stirrup welding technology, and in particular to an automatic welding equipment for stirrups of variable diameter beams. Background Technology

[0002] In municipal road and bridge construction, variable-diameter beams are a commonly used structural component. To improve construction efficiency, the structural components and internal reinforcing steel cages of variable-diameter beams are usually prefabricated. When fabricating the bottom and web steel cages of variable-diameter beams, the arranged bottom and web stirrups need to be welded into a three-in-one combined stirrup. External longitudinal bars are welded to the outside of the combined stirrup, and internal longitudinal bars are welded to the inside of the combined stirrup, thus forming the integral steel cage for the bottom and web of the variable-diameter beam.

[0003] In traditional construction operations, when fabricating combined stirrups for the bottom and web of a variable-diameter beam, workers typically need to hold down the bottom and web stirrups with one hand while manually welding them with a welding tool using the other. However, during the welding process, workers need to continuously manually press down on the bottom and web stirrups, which is not only laborious but also results in low welding efficiency. Utility Model Content

[0004] In view of the above problems, this utility model provides an automatic welding equipment for stirrups of variable diameter beams.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:

[0006] An automatic welding device for stirrups of variable diameter beams is provided, used to weld and fix the bottom plate stirrups and two web plate stirrups into a three-in-one combined stirrup. The bottom plate stirrups overlap the same ends of the two web plate stirrups. The device includes a mounting base with workstations for installing the bottom plate stirrups and two web plate stirrups. Multiple baffles are spaced along the outer side of the workstations on the mounting base for contacting the outer walls of the bottom plate / web plate stirrups.

[0011] Furthermore, a pressure plate is provided at the junction of the bottom plate stirrups and the web plate stirrups on the mounting plate to cooperate with the stop bar to clamp the bottom plate stirrups and the web plate stirrups. The pressure plate is slidably disposed on the mounting plate along the length direction of the corresponding web plate stirrup. A third cylinder is provided on the mounting plate to drive the pressure plate to move.

[0012] The beneficial effects of this utility model are as follows: Workers can install the base plate stirrups and two web plate stirrups at the work station, with both ends of the base plate stirrups overlapping the same end of each of the two web plate stirrups. The positions of the base plate stirrups and the two web plate stirrups can be positioned using a baffle; the clamping assembly can be moved upwards by a drive mechanism to clamp and fix the base plate stirrups and web plate stirrups; then, the robotic arm can be activated to automatically weld multiple contact points between the base plate stirrups and the web plate stirrups, thus reducing the labor intensity of workers and improving welding efficiency.

[0019] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0020] This application discloses an automatic welding device for stirrups of variable diameter beams, referring to... Figure 1 , Figure 2 and Figure 3 The system includes a mounting base 1, which has a workstation for installing the bottom plate stirrups 9 and two web plate stirrups 10. Multiple baffles 11 are spaced along the outer side of the workstations on the mounting base 1 to contact the outer walls of the bottom plate stirrups 9 and web plate stirrups 10. Mounting plates 2 are vertically slidably mounted on the mounting base 1 below both the bottom plate stirrups 9 and web plate stirrups 10. A driving component is mounted on the mounting base 1 to move the mounting plates 2. The mounting plates 2 are equipped with clamping components for holding and fixing the bottom plate stirrups 9 and web plate stirrups 10. A robotic arm 4 is located on the outer side of the mounting base 1, and a welding fixture 41 is mounted on the movable end of the robotic arm 4.

[0021] In this embodiment, the worker can install the bottom plate stirrup 9 and two web plate stirrups 10 at the work station, wherein the two ends of the bottom plate stirrup 9 overlap the same end of the two web plate stirrups 10. The position of the bottom plate stirrup 9 and the two web plate stirrups 10 can be positioned by the baffle 11. The clamping assembly can be moved upward by the driving component to clamp and fix the bottom plate stirrup 9 and the web plate stirrups 10. Then, the robotic arm 4 is activated, so that the welding tool 41 can automatically weld multiple parts of the bottom plate stirrup 9 and the web plate stirrups 10 that are in contact with each other. Compared with the traditional welding method, the automatic welding equipment for variable diameter beam stirrups of this application eliminates the need for workers to laboriously press the bottom plate stirrup 9 and the web plate stirrups 10, which has the effect of reducing the labor intensity of workers and improving welding efficiency.

[0022] Specifically, the driving component includes a first cylinder 3. The mounting base 1 has channels below the bottom plate stirrups 9 and the web plate stirrups 10 for vertically raising and lowering the mounting plate 2. The first cylinder 3 is located on the bottom wall of the channel, and the piston rod of the first cylinder 3 is vertically upward and bolted to the corresponding mounting plate 2.

[0023] Reference Figure 4 and Figure 5 The clamping assembly uses a finger cylinder 5, which includes a finger cylinder body 51 and two clamping blocks 52 that are slidably disposed on the top of the finger cylinder body 51. The finger cylinder body 51 is disposed on the mounting plate 2 and located inside the bottom plate stirrup 9 / web plate stirrup 10. The two clamping blocks 52 are slidably disposed on the top of the finger cylinder body 51 along the width direction of the bottom plate stirrup 9 / web plate stirrup 10. The sides of the two clamping blocks 52 that are far apart from each other are respectively in contact with the inner sidewalls of the two long sides of the bottom plate stirrup 9 / web plate stirrup 10.

[0024] In this embodiment, the upward movement of the mounting plate 2 allows the two clamping blocks 52 of the finger cylinder 5 to enter the inner side of the bottom plate stirrup 9 / web plate stirrup 10. Then, the finger cylinder 5 is activated and the two clamping blocks 52 are moved away from each other, so that they abut against the inner sidewalls of the two long sides of the bottom plate stirrup 9 / web plate stirrup 10, thereby achieving the purpose of clamping and fixing the bottom plate stirrup 9 / web plate stirrup 10.

[0025] To facilitate the placement of the bottom plate stirrups 9 and the web plate stirrups 10, the side of the baffle 11 that contacts the bottom plate stirrups 9 / web plate stirrups 10 has a first chamfer on its top. To facilitate the insertion of the clamping block 52 into the inside of the bottom plate stirrups 9 / web plate stirrups 10, the top of the clamping block 52 has a second chamfer at both ends parallel to the long side of the bottom plate stirrups 9 / web plate stirrups 10.

[0026] Furthermore, a pressing assembly 6 for pressing down and fixing the bottom plate stirrups 9 and the web plate stirrups 10 is installed on the mounting base 1. The pressing assembly 6 includes a pressing rod 61 that rotates and is mounted on the mounting base 1, and a second cylinder 62 for driving the pressing rod 61 to rotate.

One end of the pressing rod 61 is bolted to the piston rod of the second cylinder 62, and the outer wall of the other end of the pressing rod 61 is in movable contact with the bottom plate stirrups 9.

[0027] In this embodiment, the piston rod of the second cylinder 62 can be driven to extend out of the cylinder body, thereby driving the pressure rod 61 to rotate, so that the pressure rod 61 can abut against the top of the bottom plate stirrup 9, which improves the installation stability of the bottom plate stirrup 9 and the web plate stirrup 10 on the mounting base 1.

[0028] Furthermore, a pressure plate 7 is provided on the mounting plate 2 at the junction of the bottom plate stirrup 9 and the web plate stirrup 10, for cooperating with the stop bar to clamp the bottom plate stirrup 9 and the web plate stirrup 10. The pressure plate 7 is slidably disposed on the mounting plate 2 along the length direction of the corresponding web plate stirrup 10, and a third cylinder 8 is installed on the mounting plate 2 for driving the pressure plate 7 to move.

[0029] In this embodiment, the pressure plate 7 can be slid and abut against the inner sidewalls of the bottom plate stirrup 9 and the web plate stirrup 10 by the third cylinder 8, so as to cooperate with the baffle 11 to clamp the bottom plate stirrup 9 and the web plate stirrup 10, thereby further improving the installation stability of the bottom plate stirrup 9 and the web plate stirrup 10 on the mounting base 1.

[0030] The implementation principle of the automatic welding equipment for variable diameter beam stirrups in this application embodiment is as follows: The operator can install the bottom plate stirrup 9 and two web plate stirrups 10 at the work station, wherein the two ends of the bottom plate stirrup 9 overlap the same end of the two web plate stirrups 10.
