[0048] Example:

[0049] See also Figure 6 In the prior art and this embodiment, the steam box inner container includes a vertical cylinder 100 and a panel 200. Figure 1 and Figure 2The panel 200 has an opening in the middle, and the front edge of the panel 200 at the edge of the opening is sunken to form a step, and the edge of the step extends toward the front of the panel 200 to form a flange 201, and the flange 201 and the step form a sealing groove 202, which is used to install a sealing ring. Figure 3 and Figure 4 A boss 203 is formed on the back of the panel 200 at the location of the sealing groove 202. Figure 5 The vertical tube 100 is in the shape of a rectangular parallelepiped as a whole and is open at both ends. The vertical tube 100 is composed of four panels, one of which is an outer convex panel 101. Figure 6 and Figure 7 One end of the vertical tube 100 is inserted into the opening in the middle of the panel 200. When the outer wall of the vertical tube 100 is fitted with the flange 201 and the end face of the vertical tube 100 and the side edge of the flange 201 are in the same plane, the outer wall of the vertical tube 100 and the flange 201 can be welded together with high welding quality.

[0050] In order to improve the welding quality, the present embodiment provides a steamer liner welding positioning device to position the vertical tube 100 and the panel 200 during the welding process.

[0051] See also Figure 11-Figure 15 The steamer liner welding positioning device comprises a base plate 1, a positioning liner 2, a first supporting member 3, a first movable bracket 4 and a flattening member 5.

[0052] See Fig.11 , Fig.13 and Fig.15 , the positioning liner 2 is mounted on the substrate 1. The positioning liner 2 includes a column 21, a protrusion 22 arranged on the outer wall of the column 21, and a support rib 23 arranged at the end of the column 21. The axis of the column 21 is perpendicular to the substrate 1, and the column 21 is generally in the shape of a rectangular parallelepiped. There are four protrusions 22 and they are respectively arranged on the four side edges of the column 21. The support rib 23 is located at the lower end of the column 21 and between the substrate 1 and the column 21. First, the vertical tube 100 can be sleeved on the outside of the column 21, and the vertical tube 100 and the column 21 are coaxially arranged, wherein the inner wall of the vertical tube 100 and the outer wall of the column 21 are arranged at intervals to allow the four protrusions 22 to respectively abut the inner walls of the four corners of the vertical tube 100, so that the vertical tube 100 can obtain radial positioning on the substrate 1, and the lower end face of the vertical tube 100 is supported on the support rib 23, thereby the vertical tube 100 obtains axial support.

[0053] After the stand tube 100 is stably positioned on the substrate 1, the panel 200 can be sleeved onto the upper end of the stand tube 100 so that the upper end of the stand tube 100 is located at the middle opening of the panel 200. Fig.13 and Fig.14There are four first support members 3 and they are arranged in sequence along the circumference of the vertical tube 100. The first support members 3 are installed on the base plate 1 and have a relatively fixed spacing with the base plate 1 in the axial direction of the vertical tube 100. Accordingly, after the panel 200 is sleeved on the upper end of the vertical tube 100, it can obtain support along the axial direction of the vertical tube 100, so that the panel 200 can stay on the upper end of the vertical tube 100. The first support member 3 supports the panel 200 at the boss 203.

[0054] See also Fig. 9 and Fig.14 In this embodiment, the axial direction of the vertical tube 100 is the third direction, the first direction and the second direction are both parallel to the substrate 1, and the first direction, the second direction and the third direction are perpendicular to each other. In some other embodiments, the first direction and the second direction may also be in a non-perpendicular state. Among them, a fourth push-pull device 13 is provided on the substrate 1, and the fourth push-pull device 13 may be a cylinder or an electric push rod. The fourth push-pull device 13 can be extended and retracted along the second direction, and the first support member 3 arranged opposite to the outer convex plate 101 can be installed on the fourth push-pull device 13 to allow the first support member 3 to move along the second direction on the substrate 1, and then support the boss 203 on the basis of avoiding the outer convex plate 101. Since the support is a weak positioning effect, the upper end face of the vertical tube 100 and the top side edge of the flange 201 cannot be in the same plane at this time.

[0055] See also Figure 8 and Figure 10-12A third push-pull device 12 is provided on the substrate 1, and the third push-pull device 12 is transmitted to the first movable bracket 4, and the third push-pull device 12 independently controls the first movable bracket 4 to slide along the first direction on the substrate 1. A first lifting device 41 is provided on the first movable bracket 4, and the flattening member 5 is installed at the lower end of the first lifting device 41, and the flattening member 5 is driven by the first lifting device 41 to move along the third direction on the first movable bracket 4. The first lifting device 41 can also be a cylinder or an electric push rod. After the panel 200 obtains the support of the first support member 3, the third push-pull device 12 controls the first movable bracket 4 to move along the first direction, so that the flattening member 5 moves to the top of the upper end face of the vertical tube 100 and the top side edge of the flange 201. At this time, the upper end face of the vertical tube 100 and the top side edge of the flange 201 are opposite to the flattening member 5 in the third direction, and the flattening member 5 can move in the third direction, thereby squeezing and flattening the upper end face of the vertical tube 100 and the top side edge of the flange 201 at the same time, so that the upper end face of the vertical tube 100 and the top side of the flange 201 are in the same plane. After the flattening action is completed, the flattening member 5 rises again along the third direction to leave the upper end face of the vertical tube 100 and the top side edge of the flange 201, and then performs high-quality laser welding on the upper end face of the vertical tube 100 and the top side edge of the flange 201. During the welding process or before the welding action, the first movable bracket 4 can move in the first direction to move the flattening member 5 further away from the vertical tube 100 and the panel 200 to avoid interfering with the welding action.

[0056] In order to further improve the welding quality, it is necessary to maintain a close fit between the outer wall of the vertical tube 100 and the flange 201 during the welding process.

[0057] To this end, the steam box liner welding positioning device also includes radial positioning ribs 6, a lifting plate 7 and a second movable bracket 8. Figure 8-Figure 12, a second push-pull device 11 is provided on the substrate 1, and the second push-pull device 11 is transmitted to the second movable bracket 8. The second push-pull device 11 independently controls the second movable bracket 8 to move in the first direction, and the first movable bracket 4 and the second movable bracket 8 move independently in the first direction. A second lifting device 81 is installed on the second movable bracket 8, and the lifting plate 7 is installed on the second lifting device 81. The second lifting device 81 can drive the lifting plate 7 to move along the third direction on the second movable bracket 8. The radial positioning rib 6 is installed on the lifting plate 7, so the radial positioning rib 6 can at least move along the first direction and the third direction. After lifting, the flattening member 5 can avoid the radial positioning rib 6 in the horizontal direction to allow the radial positioning rib 6 to move in the first direction, so that the radial positioning rib 6 and the sealing groove 202 are opposite in the third direction, and the subsequent radial positioning rib 6 enters the sealing groove 202 through the movement in the third direction, thereby playing a positioning effect on the panel 200 along the radial direction of the vertical tube 100, so as to reduce the gap between the outer wall of the vertical tube 100 and the flange 201 during the welding process. When the radial positioning rib 6 stays at the sealing groove 202 , the projection of the radial positioning rib 6 in the third direction needs to avoid the flattening member 5 to prevent the radial positioning rib 6 from interfering with the lifting and lowering action of the flattening member 5 .

[0058] See also Fig. 9 Further preferably, a first push-pull device 72 is installed on the lifting plate 7, and the radial positioning rib 6 is installed on the first push-pull device 72. After entering the sealing groove 202, the radial positioning rib 6 can generate a pressure on the flange 201 along the radial direction of the vertical tube 100, so that the flange 201 can better fit with the outer wall of the vertical tube 100, thereby reducing the gap between the outer wall of the vertical tube 100 and the flange 201.

[0059] In addition, in this embodiment, there are at least two radial positioning ribs 6, which are arranged in sequence along the circumference of the vertical tube 100. When at least two radial positioning ribs 6 simultaneously squeeze the flange 201 radially along the vertical tube 100, it is easier to balance the force on the flange 201, thereby reducing the occurrence of the top edge of the flange 201 being misaligned with the upper end face of the vertical tube 100 due to uneven force during welding.

[0060] In this embodiment, a clearance opening 71 is provided in the middle of the lifting plate 7, and the radial positioning rib 6 passes through the clearance opening 71. A portion of the radial positioning rib 6 is located above the lifting plate 7, and a portion is located below the lifting plate 7. The radial positioning rib 6 is located at the edge of the clearance opening 71. The second movable bracket 8 can slide along the first direction to make the projections of the upper end surface of the vertical tube 100 and the sealing groove 202 in the third direction fall into the clearance opening 71, so as to allow the radial positioning rib 6 to enter the sealing groove 202 along the third direction. Since the radial positioning rib 6 is located at the edge of the clearance opening 71, the radial positioning rib 6 will not block the top side edge of the flange 201 and the upper end surface of the vertical tube 100 when moving along the third direction, so the radial positioning rib 6 will not interfere with the welding process when radially positioning the flange 201.

[0061] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
