Description

Technical Field

[0001] The utility model belongs to the technical field, and particularly relates to a positioning tooling for welding copper-plated aluminum pipe joints. Background Art

[0002] Aluminum metal has good ductility, excellent electrical and thermal conductivity, and corrosion resistance, so it is widely used as a material for various workpieces. However, aluminum parts also have some deficiencies. For example, they have poor metal fatigue. When the amplitude given by the outside world is large, they are prone to deformation and cannot return to their original state. Usually, people will plate copper on aluminum parts to solve this problem. In the field of refrigeration technology, most of the pipes used in refrigeration equipment are copper pipes, but the production cost of copper pipes is huge.

[0003] In the production of air-conditioning pipelines, since some air-conditioning pipelines need to be bent at two places, during specific production, two bent pipelines are welded. In order to ensure the alignment of the welding joints of copper-plated aluminum pipe joints, the pipelines need to be fixed at this time. Some fix the pipelines by pressing with threaded rods. This structure requires rotating the threaded rods before and after welding, which is rather inconvenient. Therefore, a positioning tooling for welding copper-plated aluminum pipe joints is needed, which can position the alignment of copper-plated aluminum pipes by means of quick clamping, so as to ensure the stability of pipeline alignment and improve the convenience of positioning. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a positioning tooling for welding copper-plated aluminum pipe joints, which positions the alignment of copper-plated aluminum pipes by means of quick clamping, so as to ensure the stability of pipeline alignment and improve the convenience of positioning, and solve the technical problems put forward in the above background art.

[0005] The technical solution of the utility model to solve the above technical problems is as follows: A positioning tooling for welding copper-plated aluminum pipe joints, which includes a welding table: Two symmetrically arranged vertical plates are fixedly installed on the top of the welding table, and a carrier table is fixedly installed on the top of the two vertical plates together. A copper-plated aluminum pipe is clamped inside the carrier table. A side plate is welded on the surface of the vertical plate. A cross plate is fixedly installed on the top of the carrier table. A rotating rod is rotatably connected to the top of the cross plate through a rotating shaft. A slide rail is fixedly installed on the top of the cross plate through a bolt. A sliding seat is slidably installed on the surface of the slide rail. A moving plate is fixedly installed on the top of the sliding seat. A clamping plate is welded on the top of the moving plate. A clamping block is fixedly installed on the surface of the clamping plate through a bolt. A connecting rod is arranged above the cross plate. An electric telescopic rod is fixedly installed on the top of the cross plate through a bolt.

[0006] Preferably, a pull rod pressing part is installed on the surface of the side plate.

[0007] Preferably, the output end of the electric telescopic rod is fixedly connected to the moving plate.

[0008] Preferably, the clamping block is an arc-shaped block, and a cushion block is pasted on the inner wall of the clamping block. The cushion block is a rubber pad.

[0009] Preferably, both ends of the connecting rod are rotatably connected to the rotating rod and the moving plate through a rotating shaft respectively.

[0010] 1. The beneficial effects of the present utility model are as follows: By the movement of the moving plate to drive the clamping plate to close to the copper-plated aluminum pipe, the clamping plate clamps and positions the copper-plated aluminum pipe through the clamping block, and the alignment of the copper-plated aluminum pipe can be positioned by a quick clamping method, so as to ensure the stability of the pipeline alignment and improve the positioning convenience.

[0011] 2. Through the setting of the pull rod pressing member, the position of the copper-plated aluminum pipe is pressed and fixed, thereby improving the stability of the copper-plated aluminum pipe during fixing and avoiding the situation that the copper-plated aluminum pipe moves during welding.

[0012] 3. Through the setting of the cushion block, the inner wall of the clamping block is cushioned to avoid the situation that the latter is damaged by extrusion when the clamping block directly contacts the copper-plated aluminum pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Embodiment 2:

[0024] Figures 1-4 Show a positioning tooling for welding of copper - plated aluminum pipe joints according to an embodiment of the present utility model, which includes a welding table 1. On the top of the welding table 1, two symmetrically arranged vertical plates 2 are fixedly installed. On the top of the two vertical plates 2, a carrier table 3 is fixedly installed together. A copper - plated aluminum pipe 4 is engaged in the inner wall of the carrier table 3. A side plate 5 is welded on the surface of the vertical plate 2. On the top of the carrier table 3, a cross - plate 7 is fixedly installed. On the top of the cross - plate 7, a rotating rod 8 is rotatably connected through a rotating shaft.
