[0037] Principle and operation process

When the servo motor 51 is started, the pipe fittings clamped by the fixture can be controlled to move toward or away from the welding machine 2 at the same time, so that automatic heating of the HVAC pipe can be realized; an electric cylinder 9 is set to be connected to the slide seat 4, and the fixture can be cooperated with to control the electric cylinder 9 to move the pipe fittings to be connected to the welding machine 2 when heating is required, and to control the pipe fittings to leave the welding machine 2 when connection is required, so that the pipe fittings can be automatically connected after heating, and the fixture can also adjust the connection angle before heating, and the automatic connection ensures the accuracy of the connection angle; a flexible anti-skid layer is set on the inner surface of the limit clamp 8, which can not only play an anti-skid role, but also better protect the pipe fittings from deformation or rupture when subjected to force.

[0039] When in use, first put the pipe fitting between the two limit clamps 8, adjust the angle and position, and by turning the torque wrench 811, turn the nut 81 to push it in the direction close to the limit clamp 8, the limit clamp 8 clamps the pipe fitting, and then the electric cylinder 9 is started, and the slide seat 4 is pushed and pulled, and the slide seat 4 slides in the slide rail 3 to control the center of the pipe fitting to reach the position coaxial with the first welding head 21 and the second welding head 22.

After the heating is completed, the servo motor reverses to control the pipe fitting to leave the first welding head 21 and the second welding head 22, and then the electric cylinder 9 is quickly started to push the slide seat 4 away from the welding machine. Then the servo motor 51 is started again to control the pipe fittings on the two fixtures to move closer to the center at the same time to complete the connection operation. The whole process only requires manual fixing of the pipe fitting to complete the automatic heating and connection operations. At the same time, by determining and fixing the angle in advance, the accuracy of the angle after welding can also be well guaranteed.
