[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-5 , the present invention provides a technical solution:

[0025] An automatic circular welding structure of a welding machine, which consists of a welding machine 1 and a turntable 6. The welding machine 1 is a rotatable structure with upper and lower parts, including an upper part welding machine main body 101 and a lower part welding head 102. On the front side of the rotatable upper part of the welding machine, there is a three-axis linear guide rail assembly 2, which keeps the posture of the upper part of the welding machine unchanged all the time, so that the wire harness of the welding machine will not be twisted and damaged. On one side of the rotatable upper part of the welding machine 1, there is a pneumatic rotary joint 3, which enables the pneumatic device on the turntable to work during rotation, facilitating the installation of devices such as cylinder grippers on the turntable. The lower surface of the pneumatic rotary joint 3 is connected to the mounting seat 11 of the welding machine 1, which can install and fix the welding machine on the turntable. The upper end surface of the mounting seat 11 is connected to a screw rod adjusting device 4, which has a position display and can conveniently adjust the relative distance between the welding machine and the product, improving the adjustability of the device. The lower end of the mounting seat 11 is connected to both sides of the welding head of the rotatable lower part of the welding machine 1, enabling the welding head to remain relatively stationary when the turntable rotates. On both sides of the lower end surface of the mounting seat 11, there are linear guide rails 12, which enable the mounting seat to be radially adjustable on the turntable. The lower surface of the screw rod adjusting device 4 is connected to the turntable for basic fixation. The lower end surface of the linear guide rail 12 is provided with a turntable 6. The lower surface of the turntable 6 is provided with a turntable support seat welding box 10, which provides support for the rotation of the turntable and also provides a relatively enclosed space for welding, facilitating light shielding and cleaning of waste gas. On the outer circle of the turntable 6, there is a large synchronous pulley 7. On the outer circle of the large synchronous pulley 7, there is a synchronous belt connecting a small synchronous pulley 8. The upper end of the small synchronous pulley 8 is connected to a servo motor 5, which is convenient for controlling and adjusting the rotation speed. The lower end of the servo motor 5 is provided with a mounting bracket 9, which can adjust the position of the motor to tension the synchronous belt.

[0026] Working principle and usage process of the present invention: After the present invention is installed, first, the position of the servo motor can be adjusted by adjusting the mounting bracket 9 to tension the synchronous belt. Then, the product to be processed is placed and fixed at the center position of the turntable 6. Subsequently, the relative position between the welding head 102 and the processed product is precisely adjusted by the adjusting screw device 4 to ensure the welding effect. When the servo motor 5 is working, the turntable 6 rotates uniformly through the synchronous pulley drive. The attitude of the upper part of the welding device body 101 on the welding device 1 is kept unchanged when the turntable 6 rotates by relying on the three-axis linear guide rail assembly 2. The number of rotations of the screw on the rotating turntable 6 is detected by the proximity switch arranged between the three-axis linear guide rail assembly 2 and the turntable 6. Relying on the pneumatic rotary joint 3 arranged between the mounting seat 11 and the welding device 1, the pneumatic device on the turntable can work during rotation, which is convenient for installing cylinders or clamping jaws on the turntable to center and clamp the product in the center. The turntable support seat welding box 10 provides support for the continuous rotation of the turntable 6 during work, enabling welding in a closed cavity to reduce light pollution and waste gas leakage. When performing circular welding, the product to be processed passes from below the turntable support seat welding box 10 to the center welding position of the turntable 6 through the table surface of this structure. The welding device 1 starts to work and stops working after rotating one circle. This automatic circular welding structure of the welding device is simple, convenient to operate, and has better efficiency than the traditional method.
