This invention relates to the field of welding technology, and provides a through-type friction stir welding apparatus and method suitable for different plate thicknesses. The through-type friction stir welding apparatus includes a long needle stirring tool, a backing block, a limiting platform, a clamp, a positioning platform, and a worktable. The long needle stirring tool is mounted on a friction stir welding machine. The backing block is disposed on a limiting groove on the limiting platform. The positioning platform is disposed on both sides of the limiting platform, and the clamp is disposed on the positioning platform. This invention utilizes a through-type friction stir welding technology with a long needle stirring tool and a backing block, which can completely eliminate the potential risks of incomplete penetration and weak bonding at the weld root. By using a backing block made of the same material as the workpiece being welded, no material loss occurs during the through-type welding process, thus eliminating defects at the start of the through-type friction stir weld.

This utility model discloses an adjustable connecting plate. The main body of the connecting plate is connected to the sliding structure on both sides of the cabinet through the first connecting part and the second connecting part on both sides. The extension length of the first connecting part and the second connecting part can be adjusted by the adjustment structure. After the first connecting plate and the second connecting plate are fastened together, they form a sliding groove to guide the sliding of the first rack and the second rack. The first connecting plate and the second connecting plate can be clamped and locked by tightening the fastening screw, thereby achieving the purpose of fixing the connecting parts on both sides. The main body of the connecting plate can be extended and adjusted independently according to the size of the cabinet without on-site cutting, which reduces the requirements for assembly and simplifies the on-site installation process.

This utility model relates to the technical field of cotton candy equipment, specifically disclosing an integrated drive device for a motor and a furnace head main shaft. The device includes a support base on which a brushless motor is mounted. A hollow motor shaft is installed inside the brushless motor, and a sugar feeding pipe is installed inside the motor shaft.
