It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details.

Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0040] Example 1

[0041] To improve welding quality and reduce welding defects, see [link / reference] Figures 1-3 This embodiment provides a welding positioning device for a stirrer blade assembly, including a base 1, a main positioning component 2, and an auxiliary positioning component 3; the main positioning component 2 and the auxiliary positioning component 3 are both fixed on the base 1; the included angle α between the main positioning component 2 and the base 1 is equal to the included angle β between the blade 41 and the reinforcing rib 42 in the assembly to be installed 4; the auxiliary positioning component 3 is provided at both ends along the length direction of the base 1.

[0042] It should be noted that the base 1 is used to support the main positioning component 2 and the auxiliary positioning component 3, that is, it serves as a welding platform; see [link / reference] Figure 1 , Figure 2 , Figure 4The main positioning component 2 is mainly used to position the reinforcing rib 42 in the component 4 to be welded and installed, so that the triangular web plate 43 connected to the reinforcing rib 42 can be stably welded to the blade 41; the auxiliary positioning component 3 is used to fix the blade 41 to the base 1, to prevent the blade 41 from moving during the welding process, to improve the welding accuracy and welding quality, to reduce the probability of welding defects (such as porosity and cracks), and thus to improve the overall performance and service life of the agitator.

[0043] It should be noted that the included angle α is determined based on the included angle β.

[0044] In the specific implementation process, the main positioning component 2 includes a first support component 21, a second support component 22, and a positioning module 23; the first support component 21 and the second support component 22 are located on the same side of the base 1 and are arranged in parallel; one side of the positioning module 23 is rotatably connected to the first support component 21 and the second support component 22 through a first locking component 5, and the other side of the positioning module 23 abuts against the base 1; the included angle between one side of the positioning module 23 and the upper surface of the base 1 is α.

[0045] For example, refer to Figures 1-3 The first support member 21 and the second support member 22 together rotatably connect one side of the positioning module 23 to the base 1, while the other side of the positioning module 23 abuts against the upper surface of the base 1 when the device is not working, and abuts against the upper surface of the blade 41 when the device is working.

[0046] For example, the reinforcing ribs 42 on both sides of the positioning module 23 may be of different sizes; the first locking member 5 is a pin with a nut, so that the pin passes through the first support member 21, the positioning module 23 and the second support member 22 at the same time and is locked by the nut. At this time, the positioning module 23 can rotate along the pin, so that the angle between the positioning module 23 and the base 1 can change.

[0047] Further, see Figures 1-5 The height of the first support member 21 is greater than the height of the second support member 22, and the first support member 21 and the second support member 22 have the same structure. It can be seen that the first support member 21 and the second support member 22 have a height difference, meaning that the positioning module 23 is positioned with a slope after being placed behind the first support member 21 and the second support member 22.

[0048] For example, see Figure 7The first support member 21 includes a vertical plate 211 and an inclined plate 212. The vertical plate 211 is vertically fixed to the base 1, and the bottom end face of the inclined plate 212 is inclinedly fixed to the top end face of the vertical plate 211. It should be noted that the second support member 22 also includes a vertical plate 211 and an inclined plate 212, but the difference is that the vertical plate 211 in the first support member 21 and the vertical plate 211 in the second support member 22 have a height difference; for example, the height of the vertical plate 211 in the first support member 21 is greater than the height of the vertical plate 211 in the second support member 22. However, it should be noted that the top ends of both the vertical plate 211 in the first support member 21 and the vertical plate 211 in the second support member 22 are horizontal to the base plate. The inclined plate 212 in the first support member 21 and the inclined plate 212 in the second support member 22 are arranged parallel to each other.

[0049] To enhance the strength of the first support member 21 and the second support member 22, a connecting stiffener 24 is also provided in both members to simultaneously connect them. For example, the connecting stiffener 24 vertically connects the vertical plate 211 in the first support member 21 to the vertical plate 211 in the second support member 22. This allows the longitudinal cross-section of the first support member 21, the second support member 22, and the connecting stiffener 24 to be trapezoidal.

[0050] In the specific implementation process, see Figure 3 At least two through holes 231 are provided at intervals along the length direction of the positioning module 23. The through holes 231 penetrate along the width direction of the positioning module 23, so that the through holes 421 on the reinforcing rib 42 in the component to be installed 4 can be quickly aligned with the through holes 231 on the positioning module 23, so as to determine the position of the triangular web 43 and the blade 41 and then carry out subsequent effective welding, which can also improve the welding accuracy.

[0051] For example, see Figure 1 To further improve the accurate positioning between the reinforcing rib 42 and the blade 41 in the component to be installed 4, and to improve the stability during the welding process, the positioning module 23 is provided with a second locking member 6 that is adapted to and connected to the through hole 231. The second locking member 6 has a guiding function and can lock the reinforcing rib 42 to the positioning module 23. For example, the second locking member 6 has the same structure as the first locking member 5.

[0052] For example, the positioning module 23 is a hollow cuboid structure, and a trapezoidal support block 232 is provided on one bottom surface of the cuboid structure. When the positioning module 23 is working, the two bottom edges of the trapezoidal support block 232 are simultaneously perpendicular to the upper surface of the blade 41, that is, the trapezoidal support 232 abuts against the upper surface of the blade 41.

[0053] In the specific implementation process, see Figures 1-5The auxiliary positioning component 3 includes positioning clamps 31, and at least two positioning clamps 31 are provided and symmetrically arranged on both sides along the length direction of the base 1. For example, four positioning clamps 31 are provided, two on each side along the length direction of the blade 41 and symmetrically arranged, so as to fix opposite sides of the blade 41 at the same time, thereby improving the stability of the blade 41.

[0054] Furthermore, the auxiliary positioning component 3 also includes angle support components 32, of which at least two are provided and arranged on both sides along the length direction of the base 1; the angle support components 32 support the blade 41 to be parallel to the base 1. For example, four angle support components 32 are provided, one at each of the four corners of the blade 41, so that the blade 41 is parallel to the base 1 while supporting the inclined side of the blade 41, further enhancing the stability of the blade 41 on the base 1.

[0055] It should be noted that, see Figure 6 The angle support 32 includes a first support block 321 and a second support block 322; the bottoms of the first support block 321 and the second support block 322 are both vertically fixed to the upper end face of the base 1; one vertical side of the second support block 322 is perpendicular to the side wall of the first support block 321, and the first support block 321 and the second support block 322 respectively support the horizontal side and the inclined side of the blade 41 on the same side.

[0056] Furthermore, the first support block 321 has an opening 3211 at one end facing the base 1 (it should be noted that the opening 3211 faces the center of the base 1), and the longitudinal section of the opening 3211 is L-shaped. The horizontal side of the L-shape extends to the bottom of the blade 41 to enhance the support stability of the blade 41. The vertical side of the L-shape can be used to block the blade 41 so as to firmly place the blade 41 in the angle support member 32 around the blade 41. The second support block 322 has a slope A at the top to fit the edge of the blade 41.

[0057] This utility model is implemented as follows:

[0058] The positioning module 23 is rotated and lifted along the side where the first support member 21 and the second support member 22 are located, so that the blade 41 in the component to be installed 4 is placed on the base 1, and is positioned on the base 1 by the auxiliary positioning member 3, so that the four corners of the blade 41 respectively overlap the angle support member 32. The angle support member 32 supports the blade 41 on the one hand, and prevents the blade 41 from shifting during the welding process on the other hand; while the positioning clamp 31 realizes the initial positioning of the blade 41 on the base 1.

[0059] Then rotate the positioning module 23 so that the side of the positioning module 23 away from the first support member 21 is placed on the upper end face of the blade 41; then, place the reinforcing ribs 42 on both sides of the positioning module 23 in the width direction, so that the through holes 421 on the reinforcing ribs 42 correspond to the through holes 231 on the positioning module 23. Since the positioning module 23 is provided with a second locking member 6 (pin, nut), the spool can be pulled out to pass through the reinforcing rib 42 on one side and then through the positioning module 23 and the reinforcing rib 42 on the other side, so as to achieve the purpose of simultaneously and quickly aligning and connecting the positioning module 23 and the reinforcing ribs 42 on both sides of the positioning module 23. Finally, use the nut to lock it to position the reinforcing rib 42 and the positioning module 23, thereby realizing the positioning of the triangular web 43 (it should be noted that the triangular web 43 and the reinforcing rib 42 are an integral structure) and the blade 41, which facilitates the subsequent welding of the weld seam a between the blade 41 and the triangular web 43 and the weld seam b between the reinforcing rib 42 and the blade 41.

[0060] After welding is completed, the second locking component 6 and the positioning clamp 31 can be removed.
