Description

Technical Field

[0001] The utility model relates to an air-cooling tool for a friction stir welding fixture. Background Art

[0002] Friction stir welding (FSW) is a solid-state welding process used to join two metal parts without melting the metal. It was invented by the Cambridge Welding Institute (TWI) in the UK in 1991. FSW is particularly useful for joining high-strength aerospace alloys and other materials that are difficult to weld using traditional welding techniques. In FSW, a hard material rotating tool (usually tungsten carbide) is inserted into the two metal parts to be joined. The tool then moves along the joining line, generating friction heat that softens the metal without melting it. The softened metal is stirred together by the rotating tool to form a solid joint. The welding heat can easily cause product deformation during the die casting welding process. After retrieval, the flexible tooling fixture for friction stir welding of special-shaped components (CN201510182845.1) is provided with an upper pressure mechanism A on the left end of the frame, a side pressure mechanism and an upper pressure mechanism B on the right end, a positioning body and an adaptive lower support mechanism are provided in the middle of the frame, the positioning body is close to the left end of the frame, the special-shaped component is positioned by the positioning body and the adaptive lower support mechanism, and is fixed by the upper pressure mechanism A, the upper pressure mechanism B and the side pressure mechanism. However, the air blowing positions of the above-mentioned friction stir welding are all at the machine end. The welding process moves with the machine tool spindle and cannot be aligned with the position where heat needs to be generated. The product has high heat and large deformation after welding, and needs to be reshaped afterwards, which affects work efficiency.

[0003] In view of the above-mentioned defects, the designers have actively carried out research and innovation in order to create a new structure of stir friction welding fixture air-cooled tooling to make it more valuable for industrial use. Utility Model Content

[0007] Preferably, in the air-cooled tooling of the friction stir welding fixture, the first clamping assembly includes a first fixed seat, the first fixed seat is connected to a first hydraulic cylinder, the first hydraulic cylinder is connected to a first hydraulic connecting plate, and the first hydraulic connecting plate is connected to a first clamping column.

[0010] Preferably, in the air-cooled tooling of the friction stir welding fixture, the connecting plate is provided with an adjustment hole, and the adjustment hole is connected to the hydraulic joint connecting seat through an adjustment bolt.

[0011] By means of the above solution, the utility model has at least the following advantages:

[0012] The utility model can realize the clamping of the product through the first clamping component, the second clamping component and the third clamping component, and at the same time realize the rapid heat dissipation problem during product processing by docking the cooling joint at the water-cooled heat dissipation joint of the product, thereby improving the flatness of the product, making the product consistent, eliminating the need for post-welding shaping, and improving production efficiency.
