Technical Field

[0001] This utility model relates to the field of welding, specifically to welding equipment. Background Technology

[0002] A cylindrical component is fixedly connected to an end cap via welding. During welding, the cylindrical component and end cap need to be axially joined together, and their positions determined. Then, a welding torch is used to weld the joint between the cylindrical component and the end cap. Circumferential welding of the joint requires rotating the welding torch 360 degrees relative to the cylindrical component. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a device structure for welding two cylindrical parts, which facilitates the welding of two cylindrical parts by workers.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A structure for a cylindrical component welding device, comprising a bed portion and a welding torch portion, wherein the welding torch portion is mounted on a vertical support of the bed portion, the bed portion includes a spindle box and a movable housing, the movable housing is connected to a horizontal first cylinder, and under the drive of the horizontal first cylinder, the movable housing can move away from or close to the spindle box, the spindle of the spindle box is connected to a rotating cover, the movable housing is provided with an auxiliary cover, the rotating cover and the auxiliary cover are symmetrically arranged on the left and right, the movable housing is connected to a bottom support plate, the bottom support plate is located between the spindle box and the movable housing, and the bottom support plate is provided with a pair of support frames capable of supporting the cylindrical component.

[0005] According to the above technical solution, the end cap is fitted into the rotating cover, and the tail end of the horizontally lying cylindrical component is fitted into the auxiliary cover. The cylindrical body is supported by a pair of support frames. Driven by the horizontal first cylinder, the movable housing moves towards the main shaft box, and the cylindrical component and end cap are joined together. The main shaft rotates, driving the end cap and cylindrical component to rotate synchronously, and the welding torch of the welding torch part welds the joint between the end cap and the cylindrical component. After the end cap and cylindrical component have rotated one revolution, the welding is completed.

[0006] A horizontal auxiliary shaft is installed inside the movable housing. An auxiliary cover is pivotally connected to one end of the horizontal auxiliary shaft, and the other end of the horizontal auxiliary shaft is connected to a horizontal second cylinder, which is mounted on the side wall of the movable housing. Driven by the horizontal first cylinder, the movable housing moves towards the main spindle box, and the cylindrical component is joined to the end cover. Subsequently, the horizontal second cylinder drives the horizontal auxiliary shaft to move axially, causing the auxiliary cover to push the cylindrical component towards the end cover, thereby tightly joining the end cover and the cylindrical component together, ensuring that the end cover and the cylindrical component rotate synchronously when the main spindle rotates.

[0007] The bottom of the bottom support plate is equipped with a roller at one end, and the other end of the bottom support plate is hinged to the movable housing. The roller contacts the bottom plate of the bed. The bottom support plate moves along the bottom plate of the bed with the movable housing.

[0008] The support frame is equipped with pulleys that contact the cylindrical component. As the end cap rotates, the cylindrical component rotates on the pulleys, which helps to reduce friction.

[0009] The welding torch assembly includes a connector fixedly connected to the lateral translation plate, an adjustment assembly fixedly connected to the connector, and a welding torch mounted on the adjustment assembly. The lateral translation plate is movably fitted onto the crossbeam of the vertical support. A horizontal guide rail is provided on the crossbeam, and the lateral translation plate is movably mounted on the crossbeam via a slider that engages with the horizontal guide rail, thus allowing the welding torch to move laterally. The adjustment assembly can adjust the height, angle, and position of the welding torch.

[0010] The adjustment assembly includes a horizontal longitudinal adjustment module, a horizontal lateral adjustment module, and a rotation module. Both the horizontal longitudinal adjustment module and the horizontal lateral adjustment module adopt a lead screw mechanism and share a lead screw nut block. The horizontal longitudinal adjustment module is fixedly connected to the connecting piece, and the rotation module is connected to the horizontal lateral adjustment module through an L-shaped component.

[0011] The rotating module includes a left clamping block and a right clamping block. A cylindrical component is fixedly connected to the right clamping block. One end of the cylindrical component has a threaded hole. A first fastening bolt fits into the connecting hole of the L component and is screwed into the threaded hole of the cylindrical component. The left clamping block and the right clamping block are connected together by a second fastening bolt.

[0012] The welding torch connector is held by the left and right clamping blocks, and the welding torch is fixed on the welding torch connector.

[0013] The horizontal longitudinal adjustment module has a first knob for driving the lead screw, and the horizontal transverse adjustment module has a second knob for driving the lead screw. The worker adjusts the horizontal longitudinal and transverse positions of the welding torch using the first and second knobs. Loosening the first fastening bolt allows the welding torch to swing left and right until a suitable position is reached, at which point the first fastening bolt is tightened. Loosening the second fastening bolt de-clamps the welding torch, allowing the left and right clamps to release it, thus adjusting the torch's height and enabling it to rotate back and forth. Once the desired position is achieved, the second fastening bolt is tightened.

[0014] The welding torch is connected to a filter, and the filter is connected to a pair of support bars. The pair of support bars are welded to a fixing component. The fixing component has a through hole, which fits tightly onto the welding torch.

[0015] This invention provides convenience for workers to weld end caps and cylindrical parts, which helps to improve welding efficiency and welding quality. Attached Figure Description
