Through-type friction stir welding apparatus and method applicable to different plate thicknesses
PendingCN122077161AEliminate incomplete penetrationeliminate riskNon-electric welding apparatusMechanical engineeringFriction stir welding
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.

An integrated drive device for motor and furnace head spindle
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. A furnace head is mounted at the upper end of the motor shaft and the sugar feeding pipe, enabling the motor shaft, sugar feeding pipe, and furnace head to rotate synchronously. This integrated drive device integrates the motor shaft of the brushless motor with the furnace head, eliminating the need for traditional drive wheels, driven wheels, and belt drive structures. By directly connecting the motor shaft of the brushless motor to the furnace head, the size of the furnace head is reduced, resulting in a simpler overall structure, lower maintenance costs, and simpler assembly requirements.
