The clamping ring 4 is a broken annular structure and is connected to the outer flap 16 at both ends. The moving block 6 passes through the guide hole 5 and extends to the lower end and is connected to the clamping ring 4.

[0030] A plurality of cylinders 13 are installed at the lower end of the mounting plate 1 corresponding to the inner ring side of the clamping ring 4, and a support rod 22 is installed at the output end of the cylinder 13, and the support rod 22 is fixedly connected to the inner ring side of the clamping ring 4;

When the two ends of the clamping ring 4 overlap, the positioning clip 19 contacts the elastic strip 21.

[0032] See also Figure 1-Figure 4 and Figure 7 As shown, when welding the turbine guide, the fixture is first placed on the welding processing table, and then the turbine guide to be welded is placed between the clamping rods 8 above the mounting plate 1. According to the welding impeller position of the turbine guide, the clamping rod 8 is selected to be initially fixed on the turbine guide in a propping or clamping manner;

[0033] When the clamping rod 8 is fixed on the turbine guide by the expansion method: at this time, the cylinder 19 is started, and the cylinder 19 drives the connecting rod 11 to swing through the pin seat 10. During the swinging process of the connecting rod 11, the unloading rod 12 is driven to swing, and the unloading rod 12 abuts against the V-shaped groove 20 on the clamping ring 4. At the same time, the positioning clamp 19 is clamped in the gap of the elastic strip 21. When the unloading rod 12 swings, the clamping ring 4 is fixed by the positioning clamp 19 and the elastic tightening of the clamping ring 4. The unloading rod 12 expands the clamping ring 4 outward, that is, the clamping ring 4 drives the clamping rod 8 on the outside to expand outward, so as to realize the expansion and fixation of the turbine guide and perform welding;

[0034] When the clamping method is selected to fix the clamping rod 8 on the turbine guide, the clamping ring 4 is initially fixed by locking the locking bolt 15 through the outward flap 16. At this time, the outer side of the clamping ring 4 is in contact with the turbine guide, and the cylinder 2 13 is started. After the cylinder 2 13 is started, the support rod 22 is driven to extend inward, and the loose clamping ring 4 is driven to expand inward, that is, the clamping ring 4 will drive the clamping rod 8 on the outside to shrink inward, so as to clamp and fix the turbine guide and perform welding.

[0035] It is important to note here: Please refer to Figure 1 - Figure 3 and Figure 4 As shown, according to the distribution position of the impeller of the turbine guide device to be welded, before welding, the number and distribution position of the clamping rods 8 will be determined first. The specific operation is to install the clamping rods 8 in the sockets 17 on the clamp seat 7 so that the clamping rods 8 present different installation positions and match the distribution position of the impeller of the turbine guide device to be welded, thereby achieving adaptive installation and facilitating the smooth progress of the welding process.

[0036] The clamp seat 7 is provided with evenly distributed insertion holes 17, and the clamp seat 7 is connected to the clamp rod 8 through the insertion holes 17, and the inner and outer ring sides of the plurality of clamp rods 8 extend to the inner and outer sides of the clamp seat 7 and form a circle;

[0037] A plurality of bolts 14 are installed at the lower end of the inner side of the mounting plate 1 corresponding to the clamping ring 4. A stabilizing rod 18 is installed at the end of the bolt 14 extending to the lower side of the clamping ring 4. The stabilizing rod 18 abuts against the clamping ring 4. A locking bolt 15 is installed on the locking seat 3. The locking bolt 15 passes through the locking seat 3 and is connected to the outer flap 16.

[0038] See also Figure 2 , Figure 5As shown, it should be noted that: in the process of opening or clamping the turbine guide, in order to improve the stability of clamping or opening, the stabilizing rod 18 is driven to move up and down by the bolt 14. When the stabilizing rod 18 moves downward, it is in close contact with the clamping ring 4 and is pressed and fixed. After the clamping ring 4 completes the above-mentioned opening or clamping, the stabilizing rod 18 is used to limit the position to avoid looseness during the clamping process.

[0039] The working principle of the utility model is as follows:

[0040] Reference Figure 1 - Figure 7 According to the impeller distribution position of the turbine guide device to be welded, before welding, the number and distribution position of the clamping rods 8 will be determined first. The specific operation is to install the clamping rods 8 in the sockets 17 on the clamping seat 7 so that the clamping rods 8 present different installation positions and match the impeller distribution position of the turbine guide device to be welded, so as to achieve adaptive installation;

[0041] First, the clamp is placed on the welding processing table, and then the turbine guide to be welded is placed between the clamping rods 8 above the mounting plate 1. According to the welding impeller position of the turbine guide, the clamping rod 8 is selected to be initially fixed on the turbine guide in a stretched or clamped manner; when the stretched manner is selected to fix the clamping rod 8 on the turbine guide: at this time, the cylinder 19 is started, and the cylinder 19 drives the connecting rod 11 to swing through the pin seat 10. During the swinging process of the connecting rod 11, the unloading rod 12 is driven to swing, and the unloading rod 12 abuts against the V-shaped groove 20 on the clamping ring 4. At the same time, the positioning clamp 19 is clamped in the gap of the elastic strip 21. When the unloading rod 12 swings, the clamping ring 4 is fixed by the positioning clamp 19 and the elastic tightening of the clamping ring 4. The unloading rod 12 expands the clamping ring 4 outward, that is, the clamping ring 4 will drive the clamping rod 8 on the outside to expand outward, so as to realize the spreading and fixing of the turbine guide for welding;

[0042] When the clamping method is selected to fix the clamp rod 8 on the turbine guide, the clamping ring 4 is initially fixed by locking the locking bolt 15 through the outer flap 16. At this time, the outer side of the clamping ring 4 is in contact with the turbine guide, and the cylinder 2 13 is started. After the cylinder 2 13 is started, the support rod 22 is driven to extend inward, and the loose clamping ring 4 is driven to expand inward, that is, the clamping ring 4 will drive the clamping rod 8 on the outside to contract inward, so as to clamp and fix the turbine guide, and then perform welding;

[0043] In summary: the welding fixture can select the clamping method according to the impeller distribution position and number of the turbine guide device to be welded, and can achieve stable clamping to ensure the normal progress of welding, avoiding the situation where the position of the turbine guide device needs to be constantly changed during welding, affecting the welding process efficiency.
