The welding machine body 2 is installed on the front end surface of the electric slider 11 through a connecting frame. A bottom plate 12 is arranged on the upper end surface of the base 1. A fixing groove is opened on the upper end surface of the bottom plate 12. An adjusting lead screw 13 is rotatably installed in the fixing groove through a bearing. The left and right symmetric thread directions of the adjusting lead screw 13 are opposite. First sliders are screwed on the left and right symmetric outer side walls of the adjusting lead screw 13. An outer ring sleeve 14 is installed on the upper end surface of the first slider. A limiting ring 15 is rotatably installed at the inner end of the outer ring sleeve 14 through a bearing. A head is installed on the right end surface of the limiting ring 15. A plurality of slots are opened on the outer side wall of the head along its circumferential direction. A spring rod 16 is installed on the upper end surface of the first slider. A plug rod 17 is installed on the upper end surface of the spring rod 16. The plug rod 17 is arranged in the slot. The electric slider 11 is a linear guide slider structure, and the device is controlled to move linearly by driving the lead screw to rotate by a motor. During operation, the materials are respectively inserted into the limiting ring 15 for fixing. The adjusting lead screw 13 is rotated to drive the outer ring sleeve 14 to move inwards, so that the materials are extruded, thereby further fixing the outer ends of the materials. The electric slider 11 is started to drive the welding machine body 2 to move downwards, so as to weld the joints of the materials. The plug rod 17 is inserted into the head to limit the limiting ring 15. The spring rod 16 is pulled down to drive the lower ring to rotate, which is convenient for welding the whole circle of the materials, without the need to remove the materials and reposition and install them, improving the work efficiency and avoiding accidents.

[0020] An adjusting groove is opened on the upper end surface of the base 1. A first lead screw 18 is rotatably installed on the left end surface of the adjusting groove through a bearing.

The bottom plate 12 is installed on the upper end surface of the adjusting slider. During operation, by rotating the handle, the first lead screw 18 is driven to rotate, which is convenient for driving the bottom plate 12 to move left and right, so that different positions of the materials can be welded.

[0021] A connecting plate is installed on the outer side wall of the insertion rod 17, and a first chuck 19 is installed at the bottom of the connecting plate. A bottom post 21 is arranged below the first chuck 19, and a limiting groove is formed on the upper end surface of the bottom post 21. During operation, when the spring rod 16 is pulled downwards, the first chuck 19 is clamped in the limiting groove, thereby positioning the spring rod 16 and further improving the stability of the device.

[0022] The inner end of the limiting ring 15 is installed with a fixture body 23 in a clamping manner through a second chuck 22. An L-shaped rod is installed on the front side end surface of the bottom plate 12, and a glass plate 24 is installed on the upper end surface of the L-shaped rod. During operation, the structure of the fixture body 23 is adopted, which is convenient for replacement according to the diameter specification of the material. The glass plate 24 can prevent the waste generated during welding from splashing, thereby avoiding harm to the front-side staff.

[0023] During specific operation, the materials are respectively inserted into the limiting ring 15 for fixation. The adjusting lead screw 13 is rotated to drive the outer ring sleeve 14 to move inwards, so that the materials are extruded, thereby further fixing the outer side ends of the materials. The electric slider 11 is started to drive the welding machine body 2 to move downwards, thereby welding the joints of the materials. The insertion rod 17 is inserted into the end head to limit the limiting ring 15. The spring rod 16 is pulled downwards to drive the lower ring to rotate, which is convenient for welding the entire circumference of the material. There is no need to remove the material and reposition and install it, improving the work efficiency and avoiding accidents.
