Above the support ring 1, there are two fixedly connected handles 8, which are respectively arranged on the left and right sides of the rotating seat 2. The inner surface of the support ring 1 is rotatably connected to the rotating seat 2. The rotating seat 2 and the support ring 1 are rotatably connected to each other through an internal annular chute. There is a certain frictional force between the rotation of the rotating seat 2 and the support ring 1. An opening 3 is provided above the rotating seat 2. An adjusting component 4 is arranged on the inner surface of the opening 3. The adjusting component 4 includes a slider 401. The left and right sides of the slider 401 are slidably connected to slide rails 402. The number of the slide rails 402 is two, and the slide rails 402 are fixedly connected to the inner surface of the opening 3. The adjusting component 4 further includes a support piece 403. The support piece 403 is fixedly connected to the upper part of the rotating seat 2. A screw rod 404 is rotatably connected to the front of the support piece 403. The screw rod 404 threadedly penetrates through the front of the slider 401. A welding component 5 is arranged below the slider 401. The welding component 5 includes an electric push rod 501. The electric push rod 501 is fixedly connected to the lower part of the slider 401. A welding device 502 is fixedly connected to the lower end of the electric push rod 501. The welding device 502 is used for laser spot welding of the annular workpiece, which is a prior art. The welding component 5 further includes a lamp 503. The lamp 503 is used for illuminating the inside of the annular workpiece to facilitate finding the gap for welding. The lamp 503 is fixedly installed below the slider 401. A clamping component 6 is arranged on the outer surface of the support ring 1.

[0024] When the above-mentioned device is in specific use, first fix the support ring 1 at the edge of the annular workpiece through the clamping assembly 6, so that the electric push rod 501 and the welding device 502 extend into the annular workpiece. At this time, illuminate the inside of the annular workpiece through the lamp 503 to facilitate finding the gap for welding. Drive the slider 401 to slide in the opening 3 by rotating the screw rod 404, so that the welding device 502 fits against the inner wall of the annular workpiece. Drive the welding device 502 to the position of the gap by the electric push rod 501. At this time, perform laser spot welding on the gap at the inner wall of the annular workpiece through the welding device 502. Rotate the rotating seat 2 to rotate it on the inner surface of the support ring 1 to drive the welding device 502 to rotate one circle on the inner wall of the annular workpiece, so as to weld the annular gap inside the annular workpiece.

[0025] Embodiment 2

[0026] See Figures 1-4 , on the basis of Embodiment 1, the clamping assembly 6 includes a sliding bar 601, the sliding bar 601 is fixedly connected to the outer surface of the support ring 1, a sliding seat 602 is movably sleeved on the outer surface of the sliding bar 601, a sliding rod 603 is fixedly connected above the sliding seat 602, and a clamping plate 604 is fixedly connected to the surface of the sliding seat 602 facing the support ring 1. The number of the clamping assemblies 6 is two groups, which are symmetrically arranged on the left and right sides of the support ring 1 respectively. A rotating assembly 7 is arranged above the clamping assembly 6. The rotating assembly 7 includes a turntable 701, the turntable 701 is threadedly sleeved on the outer surface of the support ring 1, an arc-shaped groove 702 is opened above the turntable 701, and the inner surface of the arc-shaped groove 702 is slidably connected to the sliding rod 603.

[0027] When the above-mentioned device is in specific use, when it is necessary to fix the support ring 1 at the edge of the annular workpiece, first place the support ring 1 above the edge of the annular workpiece so that the annular workpiece is located between the two clamping plates 604. At this time, rotate the turntable 701 to press the inner wall of the arc-shaped groove 702 against the sliding seat 602, thereby driving the sliding seat 602 to slide on the sliding bar 601. The sliding seat 602 will drive the clamping plate 604 to clamp the annular workpiece. Since the turntable 701 and the support ring 1 are threadedly connected, the self-locking property of the thread can make the clamping plate 604 clamp the annular workpiece, achieving the effect of facilitating fixation.
