Description

Technical Field

[0001] The utility model relates to the technical field of bellows clamping, in particular to a bellows welding clamping jig. Background Art

[0002] When welding the bellows, it is necessary to ensure the stability of the bellows during the welding process, which requires a device to clamp the bellows. The existing technology fixes the bellows through a fixed bracket. Since the fixed bracket makes the bellows have a larger range of movement on the bracket, the fixing effect is not good and it will affect the welding when the bellows are butt-jointed.

[0003] The existing patent (publication number: CN215630094U) proposes a metal corrugated pipe fixing bracket, including a fixed steel ring, a top fixed steel bar and a connecting rod fixed steel bar. The lower end of the metal corrugated pipe is sleeved with a fixed steel ring, and the fixed steel ring is fixed to the bottom steel bar of the foundation through the connecting rod fixed steel bar. The upper end of the metal corrugated pipe is clamped and fixed with the top fixed steel bar, and the top fixed steel bar is connected and fixed to the surface steel bar of the foundation.

[0004] The above-mentioned fixed bracket adopts a technical solution to solve the problem of fixing the corrugated pipe. The upper end of the metal corrugated pipe is clamped and fixed with a top fixing steel bar. The top fixing steel bar is connected and fixed to the surface steel bar of the foundation. The metal corrugated pipe is fixed using this bracket. The metal corrugated pipe does not need to be welded and fixed. The problem with this solution is that although it can also solve the problem of fixing the corrugated pipe, it will affect the welding of the corrugated pipe when it is connected. Therefore, we propose a corrugated pipe welding clamping fixture to solve the above problem. Utility Model Content

[0005] The utility model provides a bellows welding clamping jig, which solves the current technical problems of poor bellows fixing effect and inconvenience in welding when the bellows are butt-jointed.

[0006] In order to solve the above-mentioned technical problems, the utility model provides a bellows welding clamping jig, comprising two symmetrically arranged clamping assemblies, one of the two clamping assemblies being provided with a bellows body, and the other of the two clamping assemblies being aligned and spliced ​​with one of the two clamping assemblies so that the corrugated groove on the bellows body forms a clamping arrangement with the two clamping assemblies, so that the bellows body is fixed in the clamping space formed by the two clamping assemblies.

[0007] Preferably, one end of the two clamping assemblies is also fixed with a symmetrically arranged mounting assembly, and the two symmetrically arranged mounting assemblies are inserted into the mounting ports on the welding machine.

The installation components are restricted and fixed by the installation ports of the welding machine, so that the aligned and assembled clamping components will not be separated, thereby fixing the corrugated pipe body in the clamping space formed by the two clamping components.

[0009] Preferably, the clamping assembly comprises a clamping half-cylinder, one end of which is fixed with a clamping card formed with the corrugated groove, and one end of the clamping half-cylinder away from the clamping card is fixed with a fixing seat fixed with the mounting assembly.

[0010] The above technical solution is adopted: the clamping assembly includes a clamping half-cylinder, one end of the clamping half-cylinder is fixed with a clamping card that forms a clamp with the corrugated groove, and the end of the clamping half-cylinder away from the clamping card is fixed with a fixing seat fixed to the mounting assembly, so that the clamping assembly can be fixed on the mounting assembly.

[0011] Preferably, the mounting assembly comprises a mounting half-cylinder, one end of which is provided with a mounting groove cooperating with a fixing seat, and one end of the mounting half-cylinder away from the mounting groove is provided with a receiving groove required for the movement of the bellows body.

[0012] The above technical solution is adopted: the installation component includes an installation half-cylinder, one end of the installation half-cylinder is provided with an installation groove matching with the fixed seat, and the end of the installation half-cylinder away from the installation groove is provided with a receiving groove required for the movement of the bellows body, so that the bellows body part can be moved and adjusted in the receiving groove.

[0013] Preferably, the receiving grooves of the two mounting components together form a flat-topped cone-shaped structure.

[0014] The above technical solution is adopted: the receiving grooves of the two installation components together form a flat-top cone-shaped structure, which facilitates the movable adjustment of the bellows body part and also facilitates the fixation of the bellows body.

[0015] Preferably, the size of the clamping plates in the two clamping assemblies is matched to the size of the corrugated groove, and the clamping space formed by the clamping half-cylinders in the two clamping assemblies is the same size as the corrugated pipe body.

[0016] The above technical solution is adopted: by adapting the size of the clamping plates in the two clamping components to the size of the corrugated grooves, the clamping space formed by the clamping half-cylinders in the two clamping components is the same size as the bellows body, so that the bellows body will no longer shake in the clamping space formed by the clamping components.

[0017] Preferably, the fixing seats in the two clamping assemblies are fixed in the mounting grooves of the two mounting assemblies.

[0018] By adopting the above technical solution, the fixing seats in the two clamping assemblies are fixed in the mounting grooves of the two mounting assemblies, so that the clamping assemblies are firmly fixed on the mounting assemblies.

In actual use, the corrugated grooves on the bellows body are clamped by the clamping clamps in the clamping components, so that the bellows is restricted and fixed in the two clamping components. At the same time, when the two bellows bodies are butt-welded, the length of the leaked part of the bellows body in the two clamping components can be conveniently adjusted to facilitate the butt welding of the two bellows bodies. The operation is simple, convenient and practical, and the clamping is firm.

In the utility model, a mounting assembly is provided, and the mounting assembly is aligned and assembled and then clamped on the mounting port on the welding machine, so that the clamping assembly fixed on the mounting assembly will not separate after assembly, further ensuring the firmness and stability of the clamping.
