Description

Technical Field

[0001] The utility model relates to the technical field of thin film gauge welding, in particular to a tooling fixture for thin film gauge welding. Background Art

[0002] Chinese patent number "CN115846869A" discloses a fully automatic film gauge welding machine, which includes a driving mechanism, a rotating mechanism, a clamping mechanism and a welding mechanism. The rotating mechanism is connected to the work platform through a mounting seat, and the rotating mechanism is rotatably connected to the mounting seat. The rotating mechanism is connected to the output end of the driving mechanism through a transmission structure. The rotating mechanisms are two and move synchronously. One end of the rotating mechanism is relatively arranged as an installation area for installing the clamping mechanism; the welding end of the welding mechanism is placed between the clamping mechanisms, and is used to weld the film gauge and the joint placed between the clamping mechanisms. The height position of the welding mechanism is adjustable to achieve multi-angle welding; during the welding process, automatic welding is adopted, and there is no need to manually rotate the film gauge and the joint. The film gauge joint can be welded in all directions with high efficiency, avoiding problems caused by manual welding.

[0003] This device can be used for the production of thin film gauges. It does not require manual rotation of the thin film gauge and the joint, and can perform all-round welding of the thin film gauge tube joint, which is highly efficient. However, the device is clamped and fixed on the left and right sides, which is inconvenient for loading, and the thin film gauge and the joint need to be clamped separately. The thin film gauge and the joint need to rotate synchronously, which is easy to misalign. At the same time, the position of the welded head needs to be adjusted before welding, which affects the welding efficiency. Therefore, improvements are proposed. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art, which exist in that the left and right clamping fixation makes loading inconvenient, and the film gauge and the joint need to be clamped separately, and the film gauge and the joint need to rotate synchronously, which is easy to be misaligned. At the same time, the position of the welded head needs to be adjusted before welding, which affects the welding efficiency. A tooling fixture for film gauge welding is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:
