Description

Technical Field

[0001] The utility model relates to the technical field of profile processing equipment, and particularly relates to a tooling for vertical butt welding of thick plates. Background Technique

[0002] When a ship is under sectional construction, it is necessary to perform butt welding on plates. Ordinary thin plates are usually welded in a flat laying manner. However, when the plate thickness exceeds 30 mm, if the flat laying method is still used for welding, the welding efficiency is low and the welding quality is uneven. To solve the above problems, a vertical bracket for thick plate butt welding is currently made to perform vertical automatic welding on thick plates. However, the current vertical bracket can only weld plates with a fixed thickness and cannot be applied to plates with different thicknesses. At the same time, when two plates are butt-jointed, a traveling crane is required for hoisting and displacement, which is not only inconvenient to operate but also the butt-joint accuracy is not satisfactory.

[0003] Therefore, it is necessary to provide a tooling for vertical butt welding of thick plates to solve the above technical problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a tooling for vertical butt welding of thick plates to solve the deficiencies existing in the prior art, which can meet the vertical butt welding of thick plates with different thicknesses, improve the butt-joint accuracy, and reduce the difficulty of horizontal movement of thick plates.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A tooling for vertical butt welding of thick plates includes two groups of support structures and a cross beam connecting the two groups of support structures. The support structure includes a group of symmetrically arranged support frames. The support frame includes a base. A linear guide rail is provided on the top surface of the base. A triangular frame is provided on the linear guide rail. A plurality of rolling members are evenly distributed on the front end surface of the triangular frame. The rolling member includes a universal ball bracket fixed to the front end surface of the triangular frame and a rolling ball rotatably connected to the universal ball bracket. The rear end of the triangular frame is connected with a driving device. The triangular frame reciprocates along the linear guide rail under the drive of the driving device. A horizontal movement device is provided between the two groups of support structures. Both ends of the horizontal movement device are respectively located at the bottom between the two groups of support frames. The horizontal movement device includes a horizontal movement groove. Active rollers are provided at both ends of the horizontal movement groove. A motor is provided in the base. The output shaft of the motor is fixedly connected to the active roller and drives the active roller to rotate. A plurality of driven rollers are provided in the horizontal movement groove between the two active rollers.

[0007] Preferably, the driving device is a hydraulic cylinder. One end of the hydraulic cylinder is connected to the triangular frame, and the other end is connected to the base.

[0008] Preferably, a guiding groove is provided at the top of the triangular frame.

[0009] Preferably, the rolling elements are evenly distributed from top to bottom in a matrix structure on the front end face of the tripod.

[0010] Compared with the prior art, the utility model has the following advantages:

[0011] 1. By arranging a plurality of rolling elements in an array on the front end face of the tripod, when the plate is hoisted from above the tooling between the two support frames, the friction between the plate and the front end face of the tripod is sliding friction, making the insertion of the plate smoother. At the same time, when the transverse movement device is started, the plate can also move horizontally smoothly.

[0012] 2. By installing a linear guide rail and a driving device on the base, the tripod can reciprocate on the base, so that the distance between the two tripods can be adjusted according to the thickness of the plate, which is applicable to plates of different thicknesses.

[0013] 3. By placing the plate on the transverse movement device, the distance of the left-right horizontal movement of the plate can be accurately controlled, improving the docking accuracy. Description of the Drawings

[0023] As Figures 1 to 4 shown, a tooling for vertical butt welding of thick plates includes two groups of support structures and a cross beam 1 connecting the two groups of support structures. The support structure includes a group of symmetrically arranged support frames. The support frame includes a base 2. A linear guide rail 3 is provided on the top surface of the base. A triangular frame 4 is installed on the linear guide rail. Twelve rolling elements 5 are evenly distributed on the front end surface of the triangular frame from top to bottom. The twelve rolling elements are arranged in a matrix structure. The rolling element includes a universal ball bracket 501 welded and fixed to the front end surface of the triangular frame, and a rolling ball 502 rotatably connected to the universal ball bracket. The rear end of the triangular frame is connected with a driving device 6. The driving device is a hydraulic cylinder. One end of the hydraulic cylinder is connected with the triangular frame, and the other end is connected with the base. The triangular frame reciprocates along the linear guide rail under the drive of the driving device. A guiding groove 7 for conveniently inserting a plate is provided at the top of the triangular frame. A transverse movement device is installed between the two groups of support structures. The two ends of the transverse movement device are respectively located at the bottom between the two groups of support frames. The transverse movement device includes a transverse movement groove 8. Active rollers 9 are provided at both ends of the transverse movement groove. A motor 10 is installed inside the base.

[0024] As Figure 5As shown in the figure, the principle and usage method of a tooling for vertical butt welding of thick plates: Place multiple sets of toolings on the same straight line and weld them to the embedded parts on the factory floor to ensure the straightness of subsequent spliced plates. Start the hydraulic cylinders on each base, initially adjust the distance between two opposite tripods according to the thickness of the plate to be processed, use a crane to lift the plate 12, hoist the plate above the tooling, and insert the plate between two opposite tripods along the guiding groove opened at the top of the tripods. Start the hydraulic cylinders on each base again to make the front faces of the four tripods tightly abut against both sides of the plate. At the same time, the bottom of the plate falls onto the rollers of the transverse movement device. For the same toolings arranged on the side of this tooling, repeat the above steps to complete the insertion and installation of the corresponding plate. At this time, start the driving rollers of the transverse movement device to make the plate move horizontally, so that two plates to be butt welded are accurately aligned until the distance between the butt ends of the two plates meets the welding requirements. Stop the transverse movement device and start vertical automatic welding of the two plates.
