[0025] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments:

[0026] As Figures 1-3 shown, the present utility model provides a vibration friction welding tooling, including a lower die carrier 1 and an upper die carrier 2. The upper die carrier 2 is arranged above the lower die carrier 1. The top of the lower die carrier 1 is fixedly connected with a lower die block 3. The bottom end of the upper die carrier 2 is provided with a rotating module 4. The left side of the lower die block 3 is fixedly connected with a cooling mechanism 5. The rotating module 4 includes a rotating frame 41. The rotating frame 41 is rotatably connected to the front side of the bottom of the upper die carrier 2. The bottom of the rotating frame 41 is fixedly connected with an upper die block 42. A sliding groove one is opened in the middle of the bottom end of the upper die carrier 2. The front side of the inner wall of the sliding groove one is fixedly connected with a first motor 43. The output shaft of the first motor 43 is fixedly connected with a transmission screw 44. The outer surface of the transmission screw 44 is threadedly connected with a threaded slider 45. The threaded slider 45 is slidably connected inside the sliding groove one and the bottom is fixedly connected with a connecting ear plate 46. The bottom of the connecting ear plate 46 is movably connected with a rotating push plate 47. The front end of the rotating push plate 47 is movably connected with the center of the top of the rotating frame 41. Both the left and right sides of the front end of the rotating push plate 47 are fixedly connected with a transmission wheel 48. The lower part of the outer surface of the transmission wheel 48 is meshed and connected with a transmission tooth plate 49. A sliding groove two is opened in the rear side of the upper die block 42. The bottom end of the transmission tooth plate 49 penetrates to the inside of the sliding groove two. The bottom ends of the two transmission tooth plates 49 are fixedly connected with a U-shaped pulling plate 410. The U-shaped pulling plate 410 is slidably connected inside the sliding groove two. The middle part of the front side of the U-shaped pulling plate 410 is fixedly connected with a tightening spring 411. The front end of the tightening spring 411 is fixedly connected with a limit top plate 412. The limit top plate 412 is slidably connected inside the sliding groove two. The front end of the limit top plate 412 is fixedly connected with a semi-circular top block 413. The front end of the semi-circular top block 413 penetrates to the inner wall of the upper die block 42;

[0027] When picking up and placing the workpieces for vibration friction welding, by starting the first motor 43, the driving screw 44 can drive the threaded slider 45 to slide inside the first sliding groove, so that the connecting ear plate 46 and the rotating push plate 47 can push the rotating frame 41 to rotate, thereby tilting the upper module 42, which facilitates the picking up and placing of the workpieces. At the same time, by tightening the limiting top plate 412 with the tightening spring 411, the semi-circular top block 413 can tightly fix the workpiece, avoiding the dropping of the workpiece. At the same time, when the rotating frame 41 rotates back, the rotation of the rotating push plate 47 can drive the transmission wheel 48 to rotate. Thus, through the engagement with the transmission tooth plate 49, the transmission tooth plate 49 can slide and pull the U-shaped pull plate 410, thereby squeezing the tightening spring 411, making the tightening force of the semi-circular top block 413 on the workpiece greater, resulting in a better fixing effect on the workpiece and facilitating the vibration friction welding process of the workpiece.

[0028] As Figures 4-5 shown, the present utility model provides a vibration friction welding tooling. The cooling mechanism 5 includes an air inlet box 51, which is fixedly connected to the left side of the lower module 3. The right end of the air inlet box 51 is fixedly connected with a connecting pipe 52, and the right end of the connecting pipe 52 is fixedly connected with an annular flow ring 53. An installation groove is formed inside the lower module 3, and the annular flow ring 53 is fixedly connected inside the installation groove. The top of the outer surface of the annular flow ring 53 is fixedly connected with a plurality of air blowing pipes 54. The top ends of the air blowing pipes 54 penetrate to the top of the lower module 3. The top end of the inner surface of the air blowing pipe 54 is fixedly connected with a first dust-proof net 55. The middle of the inner surface of the air inlet box 51 is fixedly connected with a cross bracket 57. The middle of the cross bracket 57 is fixedly connected with a second motor 58. The output shaft of the second motor 58 is fixedly connected with a connecting shaft 59. The outer surface of the connecting shaft 59 is fixedly connected with a guide fan 510. The left side of the inner surface of the air inlet box 51 is fixedly connected with a second dust-proof net 56. The left end of the connecting shaft 59 penetrates to the left side of the second dust-proof net 56, and the upper and lower sides of the outer surface are fixedly connected with rotating plates 511. The right side of the rotating plate 511 is fixedly connected with a brush 512, and the brush 512 is arranged on the left side of the second dust-proof net 56;

[0029] After the workpiece is completed with vibration friction welding, by starting the second motor 58, the connecting shaft 59 can drive the guide fan 510 to rotate, enabling air to enter the inside of the air inlet box 51. The dust in the air can be filtered through the second dust-proof net 56. While the connecting shaft 59 is rotating, the brush 512 can be driven to rotate through the rotating plate 511, and the dust on the second dust-proof net 56 can be cleaned. Then, the air will flow inside the annular flow ring 53 under the transportation of the connecting pipe 52 and then be blown out from the air blowing pipes 54, which can cool the welding part of the workpiece by air cooling, making it more convenient to take out the welded workpiece and facilitating the use of the vibration friction welding tooling.

[0030] The working principle of the vibration friction welding tooling will be specifically described below.

[0031] As Figures 1-5 shown, when using the vibration friction welding tooling, the tooling can be installed in the friction welding equipment through the lower die holder 1 and the upper die holder 2. By starting the first motor 43, the driving screw 44 can drive the threaded slider 45 to slide, so that the rotating push plate 47 can push the rotating frame 41 and the upper die block 42 to tilt and rotate, which facilitates placing the workpiece into the upper die block 42. At the same time, the workpiece can be tightly fixed by the semi-circular top block 413. When the rotating frame 41 rotates back, the rotating push plate 47 can drive the transmission wheel 48 to rotate, and then the U-shaped pull plate 410 can be pulled through the transmission toothed plate 49, and the top spring 411 can be pressed against the semi-circular top block 413, making the fixing effect of the workpiece better and avoiding the dropping of the workpiece. After that, starting the friction welding equipment can perform vibration friction welding processing on the workpiece. After the workpiece is completed with vibration friction welding, by starting the second motor 58, the connecting shaft 59 can drive the guide fan 510 to rotate, so that air can enter the inside of the air inlet box 51 and, under the transportation of the connecting pipe 52, can circulate inside the annular circulation ring 53 and then be blown out from the air blowing pipe 54, which can perform air cooling on the welding part of the workpiece, making it more convenient to take out the welded workpiece and facilitating the use of the vibration friction welding tooling.

[0032] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
