[0044] In this embodiment of the utility model, when in use, by setting a positioning band 7 on the side of the support block 2 and arraying sliding positioning blocks 8 on the surface of the positioning band 7, and with the cooperation of the fixed positioning block 13 on the top of the support block 2 and the right-side winding structure, the positioning band 7 is quickly tightened, and the sliding positioning block 8 and the fixed positioning block 13 increase the friction between the elastic fastening structure at their inner ends and the bellows body 3 as the positioning band 7 tightens, thereby quickly positioning the bellows body 3, making it less prone to movement, and facilitating the welding of flanges at both ends of the bellows body 3.

[0045] like Figure 2 and Figure 3 As shown, in a preferred embodiment of the present invention, the pre-support structure includes a first top plate 5 and an inclined block 4. The first top plate 5 and the inclined block 4 are arranged in an array from bottom to top between adjacent support blocks 2, and an arc spring 6 is arranged in an array between the first top plate 5 and the inclined block 4.

[0046] In this embodiment of the utility model, when in use, the corrugated pipe body 3 is placed on the support block 2, and the fixing and positioning block 13 at the top of the support block 2 enters the concave groove of the corrugated pipe body 3, and the left side of the corrugated pipe body 3 abuts against the top of the first top plate 5.

[0047] By setting a pre-support structure, the corrugated pipe body 3 can be pre-supported, so that the corrugated pipe body 3 is in a suspended state, which makes it easier for the positioning belt 7 to fit and fix the corrugated pipe body 3.

[0048] like Figure 1 , Figure 3 and Figure 5 As shown, in a preferred embodiment of the present invention, the winding structure includes an electric winding rod 15 and a locking block 17. The electric winding rod 15 is located on the right side of the support block 2, and a groove 16 is provided on the side of the electric winding rod 15.

[0050] By setting up a winding structure, the positioning belt 7 can be kept taut quickly during use, and the sliding positioning block 8 and the fixed positioning block 13 increase the friction between their inner ends and the bellows body 3 as the positioning belt 7 is taut, thereby enabling rapid positioning of the bellows body 3.

[0051] like Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment of the present invention, the elastic fastening structure includes an elastic airbag top block 9, an inflatable airbag 10, and a top material 12. A movable groove 18 is provided in the middle of the sliding positioning block 8 and the fixed positioning block 13. The elastic airbag top block 9 is fixedly installed at the top of the movable groove 18, the inflatable airbag 10 is fixedly installed in the middle of the movable groove 18 and is fixedly connected to the elastic airbag top block 9, the top material 12 is provided at the bottom of the inflatable airbag 10, and a spring 11 is provided between the top material 12 and the fixed positioning block 13.

[0052] In this embodiment of the utility model, when the elastic airbag top block 9 and the fixed positioning block 13 are working, the elastic airbag top block 9 will first abut against the inner side of the concave groove on the surface of the bellows body 3, and the expansion airbag 10 will expand, driving the top material 12 to overcome the elasticity of the spring 11, so that the surface of the elastic airbag top block 9 abuts against and is fixed to the surface of the bellows body 3.

[0053] By setting an elastic fastening structure, the elastic airbag top block 9 increases the friction between the elastic airbag top block 9 and the bellows body 3 under the rebound of the spring 11 and the inflated airbag 10. This allows for quick positioning of the bellows body 3, making it less prone to movement and facilitating the welding of flanges at both ends of the bellows body 3.

[0054] like Figure 3 and Figure 5 As shown, in a preferred embodiment of the present invention, a plug 14 is fixedly installed on the right end of the support block 2, and the positioning belt 7 is movably inserted into the middle of the plug 14.

[0055] In this embodiment of the utility model, when in use, an insert block 14 is fixedly installed on the right end of the support block 2, and the positioning belt 7 is movably inserted into the middle of the insert block 14, thereby facilitating the positioning belt 7 to fix the position of the corrugated pipe body 3.

[0056] like Figure 1 , Figure 2 and Figure 3 As shown, in a preferred embodiment of the present invention, the surface of the corrugated pipe body 3 is provided with concave patterns, and the width values ​​of the sliding positioning block 8 and the fixed positioning block 13 are both equal to the width values ​​of the concave patterns on the surface of the corrugated pipe body 3.

[0057] In this embodiment of the present invention, when in use, the surface of the corrugated pipe body 3 is provided with concave patterns, and the width values ​​of the sliding positioning block 8 and the fixed positioning block 13 are both equal to the width value of the corrugated pipe body 3, thereby facilitating the insertion of the sliding positioning block 8 and the fixed positioning block 13 into the concave patterns of the corrugated pipe body 3.

[0058] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment of the present invention, the outer side of the sliding positioning block 8 is arc-shaped, and the positioning band 7 passes through the outer end of the sliding positioning block 8.

[0059] In this embodiment of the invention, when in use, the outer side of the sliding positioning block 8 is set to an arc shape, and the positioning band 7 passes through the outer end of the sliding positioning block 8, thereby facilitating the adjustment of the position and number of the sliding positioning blocks 8.

[0060] The present invention provides a high-precision welding bellows positioning device in the above embodiments. When in use, the bellows body 3 is placed on the support block 2, and the fixing positioning block 13 at the top of the support block 2 enters the concave groove of the bellows body 3.

[0061] This allows the left side of the corrugated pipe body 3 to abut against the top of the first top plate 5, and under the action of the arc spring 6, the first top plate 5 can pre-support the corrugated pipe body 3, so that the corrugated pipe body 3 is in a suspended state, which facilitates the positioning belt 7 to fit and fix the corrugated pipe body 3.

[0062] When fixing the corrugated pipe body 3 with the positioning belt 7, by pulling the positioning belt 7 on the left side of the support block 2, the sliding positioning block 8 on the surface of the positioning belt 7 can be placed in the corresponding groove of the corrugated pipe body 3. Then, one end of the positioning belt 7 is passed through the middle of the insert block 14 and fixed in the groove 16 on the surface of the electric winding rod 15 with the locking block 17. Then, the electric winding rod 15 is started, so that the excess part of the positioning belt 7 is wrapped around the surface of the electric winding rod 15, so that the positioning belt 7 is in a taut state.

[0063] At the same time, as the positioning belt 7 tightens, the sliding positioning block 8 on the surface of the positioning belt 7 and the elastic airbag top block 9 at the inner end of the fixed positioning block 13 increase the friction with the bellows body 3, thereby quickly positioning the bellows body 3, making it less prone to movement, and thus facilitating the welding of flanges at both ends of the bellows body 3.

[0064] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
