Description

Technical Field

[0001] The utility model relates to the technical field of non-standard welding equipment, in particular to a vertical seam welding workstation for a cylinder body. Background Technique

[0002] In aerospace engineering, for the welding of large-diameter and thin-walled cylinders, such as rocket bodies, etc., usually the strip materials are butt-welded end to end to form short cylinder segments, and then several cylinder segments are butt-jointed in sequence for circumferential seam welding, and finally a large cylinder is formed. When welding into short cylinder segments, longitudinal welding is required, and the weld length is long. The appearance quality requirements for the front side of the weld are: no spatter, no perforation, no porosity, no crack, and no serious oxidation. When the workpieces surrounded into a cylinder segment are welded, a weld requires the mutual cooperation of multiple personnel and auxiliary tooling from hoisting alignment to completion of welding, with a complex process, low efficiency, and unstable welding quality. And currently, there is no fixture for cylindrical workpieces. When cylindrical workpieces are welded, the tension is large. Without being clamped by a specific fixture, problems such as welding misalignment are likely to occur during welding. Content of the Utility Model

[0003] Based on this, in view of the above problems, it is necessary to provide a vertical seam welding workstation for a cylinder body.

[0004] A vertical seam welding workstation for a cylinder body includes a collapse table, a plurality of guiding roller columns and a longitudinal seam welding main machine. The plurality of guiding roller columns are vertically arranged at intervals on the collapse table and enclose a circle. The workpiece is placed on the guiding roller columns. The longitudinal seam welding main machine is arranged on the side of the collapse table, and the working part of the longitudinal seam welding main machine faces the longitudinal seam gap of the workpiece. The guiding roller columns include supporting wheels, follower roller columns, a fine-tuning support platform and a clamp seat. The clamp seat has an upper opening, and the supporting wheels are movably installed inside the upper end of the clamp seat. Two follower roller columns are connected to the side of the clamp seat, and the follower roller columns are arranged on both sides of the supporting wheels. The fine-tuning support platform is installed on the collapse table, and its output end is connected to the clamp seat to adjust the height of the clamp seat.

[0005] Preferably, the number of the guiding roller columns is nine.

[0006] Preferably, the clamp seat is rotatable.

[0007] Preferably, the side of the collapse table is provided with a step.

[0008] Preferably, the longitudinal seam welding main machine includes a main machine body, a clamping frame and a transverse moving platform. The transverse moving platform is installed inside the collapse table, the clamping frame is installed on the output end of the transverse moving platform, the main machine body is installed on the side of the collapse table, and an avoidance groove is provided on the side of the collapse table. The clamping frame penetrates through the avoidance groove, and the transverse moving platform drives the clamping frame to approach or move away from the main machine body.

[0009] The advantages of the present utility model are as follows: The supporting wheel is adopted as the specific support for the workpiece. When the workpiece rotates, the rolling friction occurs between the wheel surface of the supporting wheel and the workpiece, reducing the resistance during the rotation of the workpiece. The follower roller is in rolling friction contact with the inner and outer surfaces of the workpiece, reducing the resistance during the rotation of the workpiece. The fine-tuning support platform can adjust the height of the clamp seat, so that the apex of each supporting wheel can contact the lower edge of the workpiece, ensuring the balance of the workpiece.

When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manner.

[0014] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0015] Such as Figures 1-2As shown in the figure, a vertical seam welding workstation for a cylinder body includes a collapse platform 1, several guiding roller columns 2 and a longitudinal seam welding main machine 3. The several guiding roller columns 2 are vertically and spacedly arranged on the collapse platform 1 and enclose a circle. The workpiece 100 is placed on the guiding roller columns 2. The longitudinal seam welding main machine 3 is arranged on the side of the collapse platform 1, and the working part of the longitudinal seam welding main machine 3 faces the longitudinal seam gap of the workpiece 100. The guiding roller column 2 includes a support wheel 21, a follower roller column 22, a fine adjustment support platform 23 and a clamp seat 24. The upper end of the clamp seat 24 is open, and the support wheel 21 is movably installed inside the upper end of the clamp seat 24. Two follower roller columns 22 are connected to the side of the clamp seat 24, and the follower roller columns 22 are arranged on both sides of the support wheel 21. The fine adjustment support platform 23 is installed on the collapse platform 1, and its output end is connected to the clamp seat 24 to adjust the height of the clamp seat 24. Specifically, in this embodiment, the collapse platform 1 serves as a base, and several guiding roller columns 2 are vertically installed on the collapse platform 1 for clamping the workpiece 100. The workpiece 100 is in a cylindrical shape. By clamping with the guiding roller columns 2, the curling tension of the workpiece can be overcome, so that it remains circular and maintains the vertical state of the workpiece 100 to prevent it from tipping over. Specifically, we use a hoisting method to place the workpiece 100 on several guiding roller columns 2. When placing, the position of the workpiece 100 to be welded may not be aligned with the longitudinal seam welding main machine 2. At this time, the workpiece 100 needs to be rotated. We use the support wheel 21 as the support of the workpiece 100. When the workpiece 100 rotates, it has a rolling friction with the wheel surface of the support wheel 21, reducing the resistance when the workpiece rotates. The two follower roller columns 22 are movably inserted into the open end of the clamp seat 24 and have rolling friction contact with the inner and outer surfaces of the workpiece 100, further reducing the resistance when the workpiece 100 rotates. The fine adjustment support platform 23 adopts a threaded structure to adjust the height of the clamp seat 24 so that the apex of the support wheel 21 in each guiding roller column 2 can contact the lower edge of the workpiece 100 to ensure uniform support force.

[0016] Specifically, in this embodiment, the number of the guiding roller columns 2 is nine. In other embodiments, the number of guiding roller columns 2 can also be set according to the diameter of the workpiece 100.

[0017] Specifically, the clamp seat 24 is rotatable so that the orientation of the follower roller columns 22 can be rotated to match the clamping of the workpiece 100 and avoid jamming during clamping.

[0018] As Figure 1 shown, a step 11 is arranged on the side of the collapse platform 1 to facilitate the operator to step onto the collapse platform 1 to inspect the workpiece 100.

[0019] As Figure 1As shown in the figure, the longitudinal seam welding machine 3 includes a main body 31 of the machine, a clamping frame 32 and a transverse moving platform 33. The transverse moving platform 33 is installed in the collapse platform 1. The clamping frame 32 is installed at the output end of the transverse moving platform 33. The main body 31 of the machine is installed at the edge of the collapse platform 1. An avoidance groove 12 is provided at the edge of the collapse platform 1. The clamping frame 32 penetrates through the avoidance groove 12. The transverse moving platform 33 drives the clamping frame 32 to approach or move away from the main body 31 of the machine. Specifically, in this embodiment, the transverse moving platform 33 can adopt a lead screw assembly to drive the clamping frame 32 to horizontally displace. When the clamping frame 32 moves closer to the main body 31 of the machine cup, the two cooperate to press the longitudinal seam position of the workpiece 100. After pressing, the misalignment amount at the seam position shall not exceed ±0.1 mm to ensure the welding accuracy of the main body 31 of the machine for the workpiece 100. In this embodiment, the main body 31 of the machine adopts a laser welding machine, and a weld monitoring system is equipped in the main body 31 of the machine to facilitate viewing the seam assembly situation and the trajectory deviation situation.

[0020] The above embodiments only represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
