[0004] Although the existing light alloy seamless welding equipment can achieve seamless welding by induction or friction welding, it is limited by the use of light alloys. It is often used as a bracket and shaft parts of mechanical structures. The characteristics of such workpieces are that they are relatively slender and are easy to bend or deform during processing. In addition, it is difficult to drive the workpiece to rotate at a high speed and apply pressure when performing continuous drive friction welding to fix the workpieces, so it is inconvenient to use;

[0005] Based on the above-mentioned problems, we found that it is difficult for the existing light alloy processing and welding devices to avoid the above problems at the same time. Therefore, we proposed a light alloy seamless welding equipment that can effectively fix and drive slender workpieces, make their welding levels relatively close, and facilitate applying pressure for processing. Summary of the invention

[0006] The purpose of the present invention is to provide an existing light alloy seamless welding device and a method of using the same, which has the advantages of being able to effectively fix and drive slender workpieces, making their welding levels relatively close, and facilitating pressure application for processing.

[0007] The above technical objectives of the present invention are achieved through the following technical solutions: a light alloy seamless welding device, comprising a driving frame and a pressure frame, the pressure frame is bolted to the right side of the driving frame, the inner side of the driving frame is rotatably connected with a fixing assembly, the top of the pressure frame is bolted with a bracket, the top of the bracket is provided with a guide frame and an auxiliary frame, the inner side of the guide frame is movably connected with two active blocks, the inner side of the auxiliary frame is slidably connected with two driven blocks, the tops of the active blocks and the driven blocks are both bolted with clamping claws, the outer side of the guide frame is bolted with a cross frame, the side of the cross frame away from the guide frame is bolted with the auxiliary frame, the right side of the pressure frame is bolted with a hydraulic cylinder, and the telescopic end of the hydraulic cylinder is in contact with the right auxiliary frame;

When the welding is completed and needs to be disassembled, the reset spring can be reset by loosening the adjusting sleeve to reset the reset spring and push the fixing block to reset. When the right end material is fixed, the active block is driven to move along the guide frame. At this time, the front and rear clamps on the top thereof are The claws are close to each other and cross, and contact the material and fix it, and the driven block connected to the active block will also slide along the auxiliary frame for auxiliary clamping support. Because the clamping claws are set to be arc-shaped, the axial position of the fixed shaft parts should be close to the axial position of the material fixed by the fixed component. During processing, the driving motor drives the sleeve to rotate at high speed on the inner side of the driving frame through the driving gear. At the same time, the hydraulic cylinder presses the auxiliary frame on the right side. Because the auxiliary frame and the guide frame are connected by a cross frame, the entire guide frame and the structure on the top of the auxiliary frame and the material fixed by it will also move together, and at the same time, the inner material is pressed against the end face of the material rotating at high speed on the inner side of the fixed component for friction welding.

[0011] The present invention is further configured as follows: a bearing is bolted to the inner side of the driving frame, and the inner side of the bearing is rotatably connected to the sleeve.

At this time, the driven block (8) connected to the active block (7) will also slide along the auxiliary frame (6) for auxiliary clamping; S3. The driving motor (13) drives the sleeve (301) through the driving gear (14) to rotate at high speed along the bearing (15) on the inner side of the driving frame (1), and at the same time, the hydraulic cylinder (11) presses against the right auxiliary frame (6). Since the auxiliary frame (6) and the guide frame (5) are connected by the cross frame (10), the entire guide frame (5) and the structure on the top of the auxiliary frame (6) and the material fixed thereon will also move together, and at the same time, the inner material is pressed against the end face of the material rotating at high speed on the inner side of the fixing component (3) to perform friction welding.
