Detailed Description
The utility model provides special welding equipment convenient for a flange protective sleeve, which comprises an argon arc welding machine 6, an automatic wire feeder 4, a rack 7, a three-axis sliding table 5, an alarm 8, a sliding baffle 9, a main shaft three-jaw chuck 1 and an auxiliary three-jaw chuck 2, wherein the three-axis sliding table is arranged on the rack; the automatic welding machine is characterized by further comprising a PLC controller for controlling the three-axis sliding table 5, the main shaft three-jaw chuck 1, the argon arc welding machine 6 and the automatic wire feeder 4 to cooperate with automatic welding.
Wherein the frame 7 is used for supporting and accommodating all equipment components. And the three-axis sliding table 5 is used for adjusting the position of a welding spot according to an input instruction of the PLC 3. The argon arc welding machine 6 is used for providing welding electrical conditions, and the argon arc welding machine 6 is controlled by the PLC 7 to be turned on or turned off according to welding requirements. The three-axis gripping disk 1 rotates the welded parts according to the instructions of the PLC controller, so that different positions of the parts are welded, and the three-axis gripping disk is particularly suitable for cylindrical thermocouple sensors.
The three-axis turntable comprises a drive means 11 comprising a drive motor and a transmission gear. The PLC controls the three-axis turntable 1 to rotate by controlling the driving motor 12.
The three-jaw chuck 1 of main shaft and vice three-jaw chuck 2 are fixed by the welding part jointly, and three-jaw chuck 2 is rotatory along with three-jaw chuck 1 of main shaft, and vice three-jaw chuck 2 cooperates with lower extreme two-way guide rail 13 for various big or small protective casings of clamping prevent to weld the postdeformation during the welding. And the secondary three-jaw chuck (2) can slide along the bidirectional guide rail 13 to expose the welding part in the sheath pipe.
The PLC 3 system has a plurality of welding modes and processes for the flange protective sleeve, including a manual mode, a repair welding mode and an automatic mode; the welding process comprises the following steps: the method comprises three steps of A point welding, B continuous spot welding and C continuous fusion welding, the ABC process can be used sequentially in a connected mode, the A-B-C-AB-AC-BC-ABC has 7 welding modes, and welding program programming and archiving can be carried out according to the welding modes and the processes.
