Description

Technical Field

[0001] The invention relates to the technical field of welding tooling, and in particular to an H-shaped support block welding flip tooling. Background Art

[0002] The boiler is usually connected to multiple groups of serpentine heat pipes for heat dissipation. The serpentine heat pipes can be supported and fixed by H-shaped brackets. Figure 2 As shown, the H-shaped bracket is assembled by a first tube body 71 , a second tube body 72 and a web 73 , and welded into an H shape. Therefore, the parts to be welded of the H-shaped bracket include the first tube body 71 , the second tube body 72 and the web 73 .

[0003] Before welding, the first tube body 71, the second tube body 72 and the web 73 need to be fixed in appropriate positions and positioned until one side of the welded part is welded. In the prior art, manual positioning is mostly used, and the manual positioning is rough and inconsistent, and it is impossible to ensure that the welded part is always fixed in the appropriate position during the welding process. Therefore, the welding of the welded part is difficult, the production efficiency is low, and the production cost is high. The existing tooling fixtures cannot meet the processing and production needs of the welded part, and cannot effectively expose the welded part of the welded part, making welding difficult.

[0004] In addition, the welded part needs to be double-sided welded, that is, both sides of the welded part need to be welded, so as to improve the connection strength between the tube body and the web, improve the stress performance of the weld and the weld area, and thus improve the fatigue resistance of the welded part of the welded part. Specifically, after welding one side of the welded part, the worker needs to flip the welded part to weld the other side. It is difficult to manually flip the welded part, and improper placement during the flipping process can easily cause dimensional changes. Summary of the invention

[0005] The technical problem to be solved by the present invention is that the existing tooling has the problem of great difficulty in welding the parts to be welded on the H-shaped support block.

[0010] Optionally, the width of the avoidance window is greater than the width of the web, and the length of the avoidance window is greater than the length of the web. With the above solution, the avoidance window is suitable for completely exposing the to-be-welded portion of the to-be-welded piece when the first surface of the flip plate faces oppositely to the first surface of the workbench.

With the above solution, the workpiece to be welded is fixed on the flip plate during welding through the cooperation of the limit block, the first clamping block and the second clamping block.

[0020] Optionally, a first arc-shaped groove is formed on the first clamping block, and the first arc-shaped groove is suitable for clamping the side wall of the first tube body away from the web during welding;

[0046] In the description of this embodiment, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "provided with", "set", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this embodiment can be understood according to specific circumstances.

[0047] The present application discloses an H-shaped support block welding flip tool, which is suitable for installing the welded parts of the H-shaped support block. Figure 1 As shown, the H-shaped support block to be welded includes a first tube body 71, a second tube body 72 and a web 73. Figure 2 As shown, the H-shaped support block welding flip tool includes a workbench 1, a flip plate 2, a positioning component 3 and a support block 4.

[0048] See also Figure 2 , Figure 5 and Figure 6As shown, the flip plate 2 is rotatably connected to the first surface of the workbench 1. A through avoidance window 21 is provided on the flip plate 2. The position of the avoidance window 21 matches the position of the web 73 when the welded part is fixed on the flip plate 2. The positioning assembly 3 is arranged on the first surface of the flip plate 2. The positioning assembly 3 is suitable for fixing the welded part on the flip plate 2 during the welding process. The support block 4 is fixed on the first surface of the workbench 1. The support block 4 is suitable for supporting the web 73 when the first surface of the flip plate 2 and the first surface of the workbench 1 face the same direction.

[0049] The web 73 has a first surface and a second surface that are opposite to each other. In this embodiment, when the welded parts are fixed on the flip plate 2 , the first surface of the web 73 and the first surface of the flip plate 2 face the same direction.

[0050] The number of the support blocks 4 includes but is not limited to one or two. When the number of the support blocks 4 is only one, the support block 4 is only suitable for supporting the web 73 when the first surface of the flip plate 2 faces the same direction as the first surface of the workbench 1. When the number of the support blocks 4 is two and the two support blocks 4 are spaced apart along the width direction of the web 73, one support block 4 is suitable for supporting the second surface of the web 73 when the first surface of the flip plate 2 faces the same direction as the first surface of the workbench 1, and the other support block 4 is suitable for supporting the first surface of the web 73 when the first surface of the flip plate 2 faces the opposite direction to the first surface of the workbench 1.

[0051] In this embodiment, the number of the support block 4 is one. When the first surface of the flip plate 2 and the first surface of the workbench 1 face the same direction (such as Figure 5-6 ), the support block 4 is placed in the avoidance window 21, and the first surface of the support block 4 protrudes from the first surface of the flip plate 2 to support the second surface of the web 73. When the first surface of the flip plate 2 faces the opposite direction to the first surface of the workbench 1 (as shown in FIG. Figure 7 As shown), the support block 4 is separated from the avoidance window 21, and the avoidance window 21 exposes the seam to be welded between the second surface of the web 73 and the two tubes.

[0052] Furthermore, the width of the avoidance window 21 is greater than the width of the web 73, and the length of the avoidance window 21 is greater than the length of the web 73, so that the avoidance window 21 completely exposes the seam to be welded between the second surface of the web 73 and the two pipe bodies. When the first surface of the flip plate 2 faces the opposite direction to the first surface of the workbench 1, the worker can weld the seam to be welded between the second surface of the web 73 and the two pipe bodies through the avoidance window 21, reducing the difficulty of welding.

[0053] See also Figure 5 and Figure 7As shown, in order to ensure that the flip plate 2 flips smoothly and is still stably set on the first surface of the workbench 1 after flipping, the H-shaped support block welding flip tool also includes an articulated connector 5 and a support column 6. The first surface of the workbench 1 is provided with an articulated connector 5. The flip plate 2 is rotatably connected to the workbench 1 through the articulated connector 5. The support column 6 is provided on the flip plate 2. The support column 6 is suitable for supporting the flip plate 2 on the first surface of the workbench 1.

[0054] Furthermore, the axis of the support column 6 is perpendicular to the flip plate 2 , so that the support column 6 stably supports the flip plate 2 on the first surface of the workbench 1 .

[0055] Further, there are several support columns 6. There are several hinged connectors 5. Several support columns 6 are respectively arranged on the first surface of the flip plate 2 and the second surface opposite to the first surface, or the middle parts of several support columns 6 are assembled on the flip plate 2.

[0056] In this embodiment, the number of articulated connectors 5 and support columns 6 are the same, and their positions correspond one to one. Specifically, the flip plate 2 has a first side surface, a second side surface opposite to the first side surface, and a third side surface perpendicular to the first side surface. The articulated connector 5 is disposed on the second side surface of the flip plate 2. A plurality of articulated connectors 5 are spaced apart along the length direction of the web 73. The support column 6 is disposed close to the first side surface of the flip plate 2. The middle portion of the support column 6 is assembled on the flip plate 2, and both ends of the support column 6 extend to the outside of the flip plate 2. When the first surface of the flip plate 2 is oriented in the same direction as the first surface of the workbench 1 (such as Figure 5-6 As shown in FIG. 1 , one end of the support column 6 contacts the workbench 1, thereby providing effective support for the flip plate 2. When the first surface of the flip plate 2 faces the opposite direction to the first surface of the workbench 1 (as shown in FIG. 1 ), one end of the support column 6 contacts the workbench 1, thereby providing effective support for the flip plate 2. Figure 7 As shown), the other end of the support column 6 is in contact with the workbench 1, thereby providing effective support for the flip plate 2.

[0057] Furthermore, the support column 6 is a screw rod, and the middle part of the support column 6 is threadedly connected to the flip plate 2, so that the support column 6 is easy to repair and replace.

[0058] See also Figure 2 and Figure 5 As shown, the positioning assembly 3 is distributed on the periphery of the avoidance window 21. Specifically, the positioning assembly 3 includes a limit block 31, a first clamp block 32 and a second clamp block 33. The limit block 31 is arranged on the first surface of the flip plate 2. The limit block 31 is suitable for limiting one end of the welded part during the welding process. The first clamp block 32 is arranged on the first surface of the flip plate 2. The first clamp block 32 is suitable for clamping the side wall of the first tube body 71 during the welding process. The second clamp block 33 is arranged on the first surface of the flip plate 2. The second clamp block 33 is suitable for clamping the side wall of the second tube body 72 during the welding process.

[0059] The first clamping block 32 is provided with a first arc-shaped groove 324. The first arc-shaped groove 324 is suitable for clamping the side wall of the first tube body 71 away from the web 73 during welding. The second clamping block 33 is provided with a second arc-shaped groove 331. The second arc-shaped groove 331 is suitable for clamping the side wall of the second tube body 72 away from the web 73 during welding.

[0060] Furthermore, the number of support columns 6 is several, and the number of hinged connectors 5 is several.

[0061] In this embodiment, the limit block 31 is disposed near the third side surface of the flip plate 2. The number of the first clamping blocks 32 and the second clamping blocks 33 are the same, and the positions correspond one to one. A plurality of first clamping blocks 32 are disposed near the first side surface of the flip plate 2 and are spaced apart along the length direction of the web 73. The second clamping blocks 33 are disposed near the second side surface of the flip plate 2.

[0062] Furthermore, the spacing between the first clamp block 32 and the second clamp block 33 is adjustable so as to adapt to the webs 73 of different widths. The cooperation between the first clamp block 32 and the second clamp block 33 includes the following two modes: Mode 1, one of the clamp blocks is a fixed clamp block and the other clamp block is a movable clamp block; Mode 2, both clamp blocks are movable clamp blocks.

[0063] In this embodiment, the first clamp block 32 is a movable clamp block, and the second clamp block 33 is a fixed clamp block. Figure 2 and Figure 3 As shown, the first clamp block 32 includes a clamp block body 321, an adjusting screw 322 and a bracket 323. The clamp block body 321 is suitable for clamping the side wall of the first tube body 71 during welding. The first arc-shaped groove 324 is provided on the clamp block body 321. The adjusting screw 322 extends along the width direction of the web 73. The first end of the adjusting screw 322 is rotatably connected to an end of the clamp block body 321 away from the web 73. The bracket 323 is fixed on the first surface of the flip plate 2. The second end of the adjusting screw 322 is threadedly connected to the bracket 323 and extends to the outside of the bracket 323. The second clamp block 33 is fixed on the first surface of the flip plate 2.

[0064] For further information, see Figure 4 As shown, the adjusting screw 322 is rotatably assembled on the clamping block body 321 through a bolt.

[0065] Furthermore, in order to facilitate the rotation of the adjusting screw 322 , a handle is fixed to the end surface of the second end of the adjusting screw 322 .

[0066] Furthermore, in order to make the clamp body 321 move more smoothly, the distance between the clamp body 321 and the flip plate 2 is 0.5mm-1.5mm. The clamp body 321 does not contact the first surface of the flip plate 2, effectively avoiding friction between the clamp body 321 and the flip plate 2.

[0067] Preferably, the distance between the clamping block body 321 and the flip plate 2 is 1 mm.

[0068] In this embodiment, the specific working principle of the present invention is as follows:

[0069] Flip the flip plate 2 so that the first surface of the flip plate 2 faces the same direction as the first surface of the workbench 1;

[0070] Place the web 73 on the first surface of the support block 4, and then place the first tube 71 and the second tube 72 in the first arc groove 324 and the second arc groove 331 respectively, so that the first tube 71 and the second tube 72 are distributed on both sides of the web 73;

[0071] The adjusting screw 322 is rotated, and the first end of the adjusting screw 322 drives the first clamping block 32 to move along the width direction of the web 73, thereby adjusting the distance between the first clamping block 32 and the second clamping block 33, so that the two sides of the web 73 are closely attached to the side walls of the first tube body 71 and the second tube body 72 (such as Figure 5 wherein, during the rotation of the adjusting screw 322, the first arc-shaped groove 324 of the clamping block body 321 is always clamped on the side wall of the first tube body 71, and the clamping block body 321 is restricted by the first tube body 71, so the clamping block body 321 will not rotate with the adjusting screw 322.

[0072] The staff welds the first surface of the web 73 and the seam to be welded between the two tubes;

[0073] After welding is completed, the flip plate 2 is flipped over so that the first surface of the flip plate 2 faces opposite to the first surface of the workbench 1; at this time, the support block 4 and the avoidance window 21 are in a separated state, and the avoidance window 21 completely exposes the welded joint between the second surface of the web 73 and the two tubes (such as Figure 7 shown);

[0074] The staff welds the seam between the second surface of the web 73 and the two tube bodies;

[0075] After welding is completed, flip the flip plate 2 so that the first surface of the flip plate 2 faces the same direction as the first surface of the workbench 1; then rotate the adjusting screw 322 to adjust the distance between the first clamping block 32 and the second clamping block 33 so that the staff can remove the welded H-shaped bracket from the flip plate 2.

[0076] In general, the H-type support block welding flip tool provided in the present application effectively fixes the parts to be welded through the cooperation of the workbench, flip platform, positioning assembly and support block, thereby reducing the welding difficulty of the parts to be welded and improving production efficiency; by providing the first arc-shaped groove and the second arc-shaped groove, the first tube body and the second tube body are effectively clamped, reducing the difficulty of fixing the position of the first tube body and the second tube body; by adjusting the distance between the first clamp block and the second clamp block, it can adapt to webs of different widths.

[0077] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
