Two reinforcing bolts 331 are threadedly connected to the supporting plate 33, and the two reinforcing bolts 331 correspond to the supporting light shaft 32 and the mounting groove hole 332 respectively. The reinforcing bolt 331 corresponding to the supporting light shaft 32 is threadedly connected to one side of the supporting plate 33, and the screw rod of the reinforcing bolt 331 penetrates into the supporting plate 33 and abuts against the supporting light shaft 32, thereby fixing the supporting plate 33 on the supporting light shaft 32.

[0080] Referring to Figure 1 , Figure 5 and Figure 6 In the embodiment, the power supply port 112 is arranged on the partition plate I 11 below the fixed plate 61. The high-frequency power supply 131 is installed in the energy area 13, and the power supply end of the high-frequency power supply 131 extends to the power compartment 142 through the power supply port 112 and is electrically connected with the vertical coaxial transformer 88 through a cable. The ordinary power supply is also installed in the energy area 13, and is electrically connected with the vertical motor 64, the front-rear motor 73, the left-right motor 80 and the driving motor 25.

[0081] In the embodiment, the control panel for controlling the operation of the auxiliary supporting cylinder 27, the driving motor 25, the vertical motor 64, the front-rear motor 73, the left-right motor 80 and the high-frequency power supply 131 in the box body 1 is arranged on the front side plate of the box body 1, and the display screen for displaying the operation state of the auxiliary supporting cylinder 27, the driving motor 25, the vertical motor 64, the front-rear motor 73, the left-right motor 80 and the high-frequency power supply 131 in the box body 1 and the position information detected by the position sensor 90 is arranged above the control panel.

[0082] In this embodiment, the worker inserts the mounting base of the workpiece to be welded into the workpiece mounting hole 31 of the machining turntable 22, and then fastens the tubular part of the workpiece to be welded to the support plate 33 on the optical axis by the reinforcing bolt 331. Then the control drive motor 25 is operated to drive the cam divider 21 to rotate the machining turntable 22 by 180°, and then the support optical shaft 32 with the workpiece to be welded is moved to the welding area of the welding port 111. Then the operation of the vertical motor 64, the front and rear motor 73 and the left and right motor 80 is controlled to adjust the position of the electromagnetic induction welding head 4, so that the helical center at the end of the electromagnetic induction welding head 4 corresponds to the axial direction of the tubular part of the workpiece to be welded. Then the auxiliary supporting cylinder 27 below the workpiece to be welded is started, the output shaft of the auxiliary supporting cylinder 27 extends out of the auxiliary supporting hole 26 and enters the corresponding workpiece mounting hole 31 to push the mounting base of the workpiece to be welded to rise until the tubular part of the workpiece to be welded is inserted into the inner hole of the mounting base. At this time, if the connecting part between the tubular part of the workpiece to be welded and the mounting base is not in the welding area of the electromagnetic induction welding head 4, the electromagnetic induction welding head 4 is moved to the welding position of the workpiece to be welded by controlling the vertical motor 64. Then the coaxial transformer 88 is powered by the high-frequency power supply 131, and the electromagnetic induction welding head 4 with a helical end heats the welding position of the workpiece to be welded by the coaxial transformer 88, so that the solder in the mounting base of the workpiece to be welded melts and fully contacts the tubular part of the workpiece to be welded, and the welding of the workpiece mounting base and the workpiece tubular part is realized.

[0083] After the workpiece is welded, the output shaft of the auxiliary supporting cylinder 27 is controlled to descend and return to the initial state, and then the electromagnetic induction welding head 4 is moved below the mounting base of the workpiece to separate the electromagnetic induction welding head 4 from the workpiece. Then the cam divider 21 is driven by the drive motor 25 to rotate the machining turntable 22 by 180°, so that the welded workpiece is moved to the machining bin 141 bin opening, and then the worker dismounts the welded workpiece from the corresponding support plate 33 to complete the production of the workpiece.

[0084] During the whole welding process of the workpiece, the worker only needs to install the workpiece to be welded in the corresponding work station, and then controls the operation of each operating part, so that manual welding of the workpiece is not needed, which not only greatly reduces the labor amount, but also avoids direct contact between the worker and the electromagnetic induction welding head 4, so that the safety is higher. At the same time, since the movement of the electromagnetic induction welding head 4 is mechanical operation, the stability during welding is better, so that the welding quality of the workpiece is higher. In addition, during the welding process, the temperature probe 51 can monitor the welding area in real time, and the worker can clearly understand the temperature during welding through the temperature control display 52, so that it is easier to control the welding quality by the welding temperature, and the welding quality is avoided to be reduced due to too high or too low temperature during welding.

After the two workpieces at the welding port 111 are welded, the electromagnetic induction welding head 4 at the welding port 111 can weld the workpieces that have not been welded after the machining turntable 22 is driven to rotate 180° by the driving motor 25 through the cam divider 21, thereby accelerating the welding of the workpieces and greatly improving the welding efficiency of the workpieces.

[0104] S8: After the welding of the workpiece to be welded is completed, the output shaft of the auxiliary supporting cylinder 27 corresponding to the welding interface 111 is controlled to retract until the output shaft of the auxiliary supporting cylinder 27 is completely retracted into the corresponding auxiliary supporting hole 26.

[0105] S9: Adjust the position of the electromagnetic induction welding head 4 by controlling the operation of the vertical motor 64, the front and rear motor 73 and the left and right motor 80, so that the workpiece to be welded is separated from the welding area of the electromagnetic induction welding head 4.

[0106] S10: after the electromagnetic induction welding head 4 is separated from the workpiece to be welded, the driving motor 25 is started, the driving motor 25 drives the machining turntable 22 to rotate 180° through the cam divider 21, and then the driving motor 25 is turned off. At this time, the workpiece after welding is moved to the warehouse opening of the machining warehouse 141, and the workpiece mounting hole 31 provided with the workpiece to be welded is moved to above the auxiliary supporting hole 26 corresponding to the welding port 111 and corresponds to it.

[0107] S11: the reinforcing bolt 331 for fastening the workpiece is loosened and moved to the warehouse opening of the machining warehouse 141, and the workpiece after welding is taken off from the supporting plate 33.

[0108] S12: repeat steps S3-S11 until the welding of the same batch of workpieces is completed.

In the whole welding process, the worker only needs to complete the installation of the workpiece to be welded, the disassembly of the workpiece after welding, and the control of the operation of each power component and cylinder, so that the labor intensity is low and the safety is high.
