[0002] The vibration force in the vibration friction welding process has an important influence on the quality of the welded joint. Excessive vibration force may lead to unstable joint quality. The introduction of a shock absorbing device can effectively reduce the impact of vibration force on the welded joint and improve the welding quality. Therefore, it is necessary to design a vibration head of a vibration friction welding machine with a vibration absorbing device.

[0003] To this end, the patent with publication number CN213166916U discloses the technical field of plastic welding machines, specifically a vibration head of a vibration friction welding machine with a vibration reduction device, including a mounting seat, a vibration reduction mechanism and a vibration module, wherein the mounting seats are arranged in two parallel positions, and each mounting seat is provided with two groups of stacked vibration reduction mechanisms, and each vibration module is provided with two parallel electromagnet seats, and the two electromagnet seats are respectively arranged on the vibration isolation chlorine rubber blocks on the two mounting seats, and electromagnets are arranged on the two electromagnet seats, and a vibration base plate is arranged between the two electromagnet seats, and both ends of the vibration base plate are provided with vibration armatures, and vibration springs are arranged on both sides of the vibration base plate, and multiple waist-shaped holes with equal width on the side of the vibration spring are changed to equidistantly distributed elliptical through holes, so that the spacing between the two adjacent elliptical through holes is changed from equal width to a roughly small gradual width, thereby reducing the rigidity of the vibration spring and enhancing the vibration frequency of the vibration head;

[0004] Although the vibration head of the vibration friction welding machine with a vibration reduction device has a good shock-absorbing effect when in use, it is inconvenient to quickly replace the vibration head due to the great damage to the vibration head caused by friction welding. Therefore, it is necessary to design a vibration head that is easy to disassemble and replace. Utility Model Content
