Description

Technical Field

[0001] The invention relates to the field of friction welding processing, and in particular to a friction welding processing jig. Background Art

[0002] Friction welding refers to a welding method that uses the heat generated by the friction between the contact surfaces of the workpieces as a heat source to cause the workpieces to undergo plastic deformation under pressure. It has been increasingly widely used in new technology and traditional industrial sectors such as aerospace, automobiles, and machinery manufacturing.

[0003] With the rise of new energy vehicles, structures different from traditional fuel vehicles have emerged. New energy vehicles with intelligent driving are more popular. Intelligent driving requires chips with higher computing power to meet the needs of new energy vehicles to handle complex traffic conditions. After running for a long time, the chip generates a lot of heat and needs to be cooled. Manufacturers set up a water cooling system on the outer shell that wraps the chip to reduce the temperature generated by the chip.

[0004] When the water cooling system is manufactured, a cavity is opened on the outer shell, and the cavity is covered by a cover plate, leaving a liquid inlet and a liquid outlet for water circulation. The outer shell and the cover plate need to be welded together to prevent water in the cavity from flowing out. The welding mechanism needs to continuously move and weld at the connection between the outer shell and the cover plate. Since both the outer shell and the cover plate need to be fixed during welding, in order to avoid interference, the manufacturer chooses to vertically fix the cover plate through a fixing device. The fixing device needs to be adjusted one by one during production, resulting in low production efficiency.

[0005] Therefore, it is necessary to develop a friction welding tool to solve the above problems. Utility Model Content
