Description

Technical Field

[0001] This utility model relates to the field of rocket propellant tank technology, and in particular to a tooling for hand-held resistance welding of rocket propellant tank stringers and reinforcing plates. Background Technology

[0002] Rocket propellant tanks are crucial components of launch vehicles. They not only store and transport propellant but also serve as the main load-bearing structure, providing reliable structural support. Therefore, during the production of rocket propellant tanks, it is common practice to weld stringers onto them to enhance their overall load-bearing capacity.

[0003] Stringers are typically made by bending stainless steel plates with a thickness of 0.5mm-1.5mm. Therefore, stringers with different cross-sectional dimensions after bending will have different bending section moduli, resulting in different bending performance. The length of the stringer also affects its bending performance. Generally, among two stringers of the same material and length but different cross-sectional dimensions, the stringer with the thicker cross-section will have a relatively larger bending section modulus and thus better bending performance. Conversely, among two stringers of the same material and cross-sectional dimensions but different lengths, the shorter stringer will have relatively better bending performance.

[0004] When the stringers are welded to different locations on the rocket propellant tank, the load on each location will vary because the load on different locations on the propellant tank is different. When the load on a certain location on the stringer exceeds the stringer's maximum load capacity, the stringer will deform or break at that location, leading to serious consequences.

[0005] Currently, the solution to the above problems is to have operators hand-hold resistance welding pliers to weld at locations on the stringers that bear the greatest load, thereby increasing the stringers' load-bearing capacity at those locations and preventing deformation or breakage. Traditional hand-held resistance welding pliers are suspended from a fixed bracket above the welding machine via a pull-wire spring balancer, and the operator controls the welding position and actions by holding the handle of the pliers.

[0006] However, when operators weld reinforcing plates onto the stringers using handheld resistance welding pliers, the weight of the pliers significantly increases their workload and leads to faster fatigue, thus increasing labor costs and reducing welding efficiency. Furthermore, because the handheld resistance welding pliers are suspended on spring ropes and can swing freely, it is inconvenient for operators to position the electrode arm correctly on the stringers, easily resulting in weld misalignment and compromising the weld quality between the stringers and reinforcing plates.

[0007] Therefore, how to reduce the labor cost of welding stringers and reinforcing plates, while increasing welding efficiency and avoiding welding misalignment, and thus ensuring a good welding effect between stringers and reinforcing plates, has become an urgent problem to be solved.

[0054] Unless otherwise specified, in this invention, the connection between the support beams can be made by any connection method known in the art, such as welding, and is not particularly limited herein.

[0055] Unless otherwise specified, in this invention, the support beams can be made of metal materials known in the art, such as stainless steel or carbon steel, and are not specifically limited herein.

[0056] Unless otherwise specified, in this invention, the support beams can all be rectangular (square) structures, and the edges of the support beams are chamfered. All of the above are prior art known in the art and will not be elaborated upon further.

[0057] In this utility model, the handheld welding clamp 23, the stringer 24, and the reinforcing plate 25 are all prior art known in the art, and will not be described in detail here.

[0058] This utility model provides a tooling for hand-held resistance welding of rocket propellant tank stringers and reinforcing plates. The tooling includes at least a support mechanism and an installation mechanism, wherein:

[0059] The support mechanism includes a second support beam 2, on which a first support beam 1 is mounted.

[0060] In this embodiment, refer to Figure 1 or Figure 2 The first support beam 1 and the second support beam 2 are set perpendicularly.

[0061] Furthermore, referring to Figure 1 or Figure 2 There can be two first support beams 1, and the two first support beams 1 are respectively installed at both ends of the second support beam 2. For example, the two first support beams 1 can be arranged parallel to each other, thereby bringing a more balanced support effect to this tooling.

[0062] In this embodiment, refer to Figure 1 or Figure 2 The connection between the second support beam 2 and the first support beam 1 is located at the center of the first support beam 1.

[0063] According to one embodiment of the present invention, referring to Figure 1 or Figure 2A fifth support beam 5 is mounted on the top of the second support beam 2. A mounting mechanism is installed on the fifth support beam 5, and the mounting mechanism is used to mount a handheld welding clamp 23. A sixth support beam 7 is mounted on the top of the fifth support beam 5, and the stringer 24 is placed on the sixth support beam 7. (Refer to...) Figure 11 The reinforcing plate 25 is placed at the position where the stringer 24 needs to be reinforced.

[0064] In this embodiment, refer to Figure 1 or Figure 2 The fifth support beam 5 is installed vertically at the top of the second support beam 2, that is, the fifth support beam 5 is set perpendicular to the second support beam 2.

[0065] In this embodiment, refer to Figure 1 or Figure 2 The sixth support beam 7 is set perpendicular to the fifth support beam 5 and parallel to the second support beam 2.

[0066] In this embodiment, refer to Figure 1 or Figure 2 A reinforcing rib is provided at the connection between the fifth support beam 5 and the second support beam 2. The reinforcing rib can be a right-angled triangle structure, and the two right-angled sides of the reinforcing rib can be welded to the side wall of the fifth support beam 5 and the top of the second support beam 2 respectively (the welding method is known in the art).

[0067] In this embodiment, by setting reinforcing ribs, the connection stability between the fifth support beam 5 and the second support beam 2 can be improved, thereby improving the overall stability of the tooling.

[0068] Furthermore, referring to Figure 1 or Figure 2 There can be two fifth support beams 5, and the two fifth support beams 5 are symmetrically arranged with respect to the center position of the second support beam 2. The two fifth support beams 5 are arranged in parallel, and the two mounting mechanisms installed on the two fifth support beams 5 are arranged correspondingly (i.e., relative to each other). Among them, the two sixth support beams 7 installed at the top of the two fifth support beams 5 are arranged in parallel, and there is a gap between the two sixth support beams 7.

[0069] In this embodiment, the length of the gap between the two sixth support beams 7 is greater than the width of the electrode below the handheld welding clamp 23, so as to ensure that the electrode below the handheld welding clamp 23 can contact the bottom end of the stringer 24 through the gap between the two sixth support beams 7.

[0070] In this embodiment, refer to Figure 8-9 and Figure 11 When the handheld welding clamp 23 is mounted on the mounting mechanism (refer to...) Figure 8 or Figure 9The electrodes of the hand-held welding clamp 23 are set to correspond to the positions of the stringer 24 that need to be reinforced, so as to weld the stringer 24 and the reinforcing plate 25.

[0071] When there are two sixth support beams 7, the gap between the two sixth support beams 7 allows for proper installation of the hand-held welding clamp 23 on the mounting mechanism (see reference). Figure 8 or Figure 9 The electrode below the hand-held welding clamp 23 can contact the bottom end of the stringer 24 through the gap between the two sixth support beams 7 for welding the stringer 24 and the reinforcing plate 25.

[0072] According to one embodiment of the present invention, referring to Figure 1 or Figure 2 Several casters 10 are installed at the bottom end of the first support beam 1.

[0073] In this embodiment, the connection between the caster wheel 10 and the first support beam 1 can be a method known in the art, such as welding, and is not particularly limited here.

[0074] In this embodiment, refer to Figure 1 or Figure 2 Each first support beam 1 can be equipped with two casters 10 at its bottom end, and the two casters 10 can be arranged at both ends of the bottom of the first support beam 1 in sequence, so as to bring a more balanced support effect to this fixture.

[0075] In this embodiment, the universal wheels 10 make it easier to move the tooling.

[0076] According to one embodiment of the present invention, referring to Figure 1 or Figure 2 A first lead screw 11 is threadedly connected to the second support beam 2 along the vertical direction (i.e., perpendicular to the second support beam 2), and a brake block 12 is installed at the bottom end of the first lead screw 11.

[0077] In this embodiment, refer to Figure 1 or Figure 2 The first lead screw 11 can be installed at the center of the second support beam 2.

[0078] In this embodiment, refer to Figure 1 or Figure 2The first lead screw 11 can pass entirely through the second support beam 2 and be threaded onto the second support beam 2, thereby being installed on the second support beam 2. For example, a first lead screw through hole is opened in the second support beam 2 in the vertical direction, and a nut adapted to the first lead screw 11 is welded at each end of the first lead screw through hole (i.e., the top and bottom ends of the second support beam 2), and both nuts are set corresponding to the first lead screw through hole, thereby threading the first lead screw 11 to the second support beam 2 through these two nuts.

[0079] In this embodiment, refer to Figure 1 or Figure 2 The first lead screw 11 is set parallel to the fifth support beam 5.

[0080] In this embodiment, the connection between the first lead screw 11 and the brake block 12 can be a method known in the art, such as welding, and is not particularly limited here.

[0081] In addition, the connection between the first lead screw 11 and the brake block 12 can also be a threaded connection, that is, the first lead screw 11 is directly connected to the brake block 12 through its own thread.

[0082] In this embodiment, refer to Figure 1 or Figure 2 The brake block 12 can be a cylindrical structure.

[0083] In this embodiment, when welding work is required using this fixture, after moving the fixture to the designated position via the caster wheel 10, the first lead screw 11 can be turned downwards until the brake block 12 contacts the ground. This ensures the stability of the fixture during operation and prevents it from moving during welding work.

[0084] Furthermore, an anti-slip layer can be fixedly installed at the bottom of the brake block 12 to further improve the braking performance of the brake block 12 and better ensure the stability of this tooling during operation. The anti-slip layer can be made of materials known in the art, such as rubber or silicone, which can increase friction, and is not particularly limited here.

[0085] Furthermore, the first lead screw 11 and the brake block 12 not only provide a braking effect for this tooling, but also further improve the stability of the tooling support. For example, when the handheld welding clamp 23 is mounted on this tooling for welding work, the first lead screw 11 and the brake block 12 can also provide support for the middle part of the second support beam 2, thus providing better support for this tooling and further improving the stability of the tooling support.

[0086] According to one embodiment of the present invention, referring to Figure 2 or Figure 9 A C-shaped beam 8 is provided between the two fifth support beams 5. The two ends of the C-shaped beam 8 are connected to the side walls of the two fifth support beams 5 by two bolts (connection methods known in the art).

[0087] In this embodiment, refer to Figure 2 The C-shaped beam 8 can be a structure with two 90-degree angles.

[0088] In this embodiment, refer to Figure 2 The C-shaped beam 8 can be installed at the end of the fifth support beam 5 near the sixth support beam 7, that is, the C-shaped beam 8 can be installed... Figure 2 The fifth support beam 5 is located relatively high up.

[0089] In this embodiment, refer to Figure 2 The two short beams of the C-shaped beam 8 (i.e., the beams connected to the fifth support beam 5) are set perpendicular to the fifth support beam 5, while the long beam of the C-shaped beam 8 (i.e., the beam connected to the two short beams) is set parallel to the second support beam 2.

[0090] In this embodiment, the C-beam 8 facilitates the movement of the tooling. For example, when the tooling needs to be moved, the operator can use the C-beam 8 to push or pull the tooling (e.g., by holding the C-beam 8 to push or pull the tooling), thus making the tooling easier to move.

[0091] Furthermore, when the handheld welding clamp 23 is installed on the mounting mechanism on the fifth support beam 5, refer to Figure 8 The handheld welding clamp 23 will cause the two fifth support beams 5 to slightly deform towards each other due to its own weight. The C-shaped beam 8 provides support for the two fifth support beams 5, thereby greatly reducing the deformation of the fifth support beams 5 and ensuring the good support effect of this fixture.

[0092] According to one embodiment of the present invention, referring to Figure 1 or Figure 2 , Figure 8 or Figure 9 The top of each of the two sixth support beams 7 is equipped with a guide groove 9. The guide groove 9 has the same length as the sixth support beam 7 and is arranged parallel to the sixth support beam 7. The guide groove 9 is adapted to the shape of the stringer 24 and is used to place the stringer 24.

[0093] In this embodiment, refer to Figure 7 The vertical section of the guide groove 9 can be a concave structure, and the stringer 24 can be placed in the groove of the concave structure of the guide groove 9.

[0094] In this embodiment, the guide groove 9 can be connected to the sixth support beam 7 in a manner known in the art, such as by bolts.

[0095] In this embodiment, the guide groove 9 can be made of nylon material known in the art.

[0096] According to one embodiment of the present invention, referring to Figure 1 or Figure 2 Each first support beam 1 has a third support beam 3 installed at its top, and the third support beam 3 is connected to the bottom end of the sixth support beam 7.

[0097] In this embodiment, refer to Figure 1 or Figure 2 The third support beam 3 can be installed at the center of the first support beam 1 and vertically set at the top of the first support beam 1 (i.e., perpendicular to the first support beam 1 and parallel to the fifth support beam 5).

[0098] In this embodiment, the support effect of this tooling can be further improved by setting the third support beam 3.

[0099] According to one embodiment of the present invention, referring to Figure 1 or Figure 2 A connecting beam 6 is provided between the third support beam 3 and the fifth support beam 5. The connecting beam 6 can be a cuboid structure. The two ends of the connecting beam 6 can be connected to the third support beam 3 and the fifth support beam 5 respectively by welding.

[0100] In this embodiment, refer to Figure 1 or Figure 2 The connecting beam 6 can be set parallel to the second support beam 2.

[0101] In this embodiment, refer to Figure 1 or Figure 2 The connecting beam 6 can be set near the middle of the third support beam 3 or the fifth support beam 5.

[0102] In this embodiment, the supporting effect of this tooling can be further improved by setting the connecting beam 6.

[0103] According to one embodiment of the present invention, referring to Figure 1 or Figure 2 A fourth support beam 4 is provided between the third support beam 3 and the first support beam 1. The two ends of the fourth support beam 4 are connected to the side wall of the third support beam 3 and the top of the first support beam 1, respectively.

[0104] In this embodiment, refer to Figure 1 or Figure 2The number of fourth support beams 4 between each third support beam 3 and the first support beam 1 can be two, and they are symmetrically arranged on both sides of the third support beam 3 with the third support beam 3 as the axis of symmetry.

[0105] In this embodiment, refer to Figure 1 or Figure 2 The fourth support beam 4, the third support beam 3, and the first support beam 1 will form a triangular structure, which can further improve the support effect of this tooling.

[0106] According to one embodiment of the present invention, referring to Figure 4 The installation mechanism includes a connecting block 18 installed on the fifth support beam 5.

[0107] In this embodiment, refer to Figure 4 The connecting block 18 can be a U-shaped structure, and the groove of the U-shaped connecting block 18 can be the same width as the fifth support beam 5 and thus be installed on the fifth support beam 5. The connection method between the connecting block 18 and the fifth support beam 5 can be a method known in the art, such as welding.

[0108] According to one embodiment of the present invention, referring to Figure 4 The connecting block 18 is threaded with a second lead screw 19 that is parallel to the fifth support beam 5.

[0109] In this embodiment, refer to Figure 4 The second lead screw 19 can pass through the connecting block 18 as a whole and be threaded into the connecting block 18, thereby connecting with the connecting block 18.

[0110] According to one embodiment of the present invention, referring to Figure 4-6 The upper limit of the side wall of the fifth support beam 5 is slidably installed with a first support block 13. The two first support blocks 13 installed on the two fifth support beams 5 are correspondingly set (i.e., relative to each other). The bottom end of the first support block 13 abuts against the top end of the second lead screw 19.

[0111] In this embodiment, refer to Figure 5 or Figure 6 The first support block 13 can be an L-shaped structure, and the bending angle can be ninety degrees.

[0112] In this embodiment, refer to Figure 5 or Figure 6 For ease of description, the vertical part of the first support block 13 after bending is called the vertical first support block, and the horizontal part of the first support block 13 after bending is called the horizontal first support block.

[0113] In this embodiment, refer to Figure 4The side wall of the first vertical support block is slidably connected to the side wall of the fifth support beam 5.

[0114] Preferably, refer to Figure 4-6 A second oblong hole 20 is provided on the first support block 13 (i.e., on the vertical first support block), and the second oblong hole 20 is arranged parallel to the second lead screw 19. A second limiting bolt 22 is threaded onto the fifth support beam 5. The threaded rod of the second limiting bolt 22 is located inside the second oblong hole 20 and slides in engagement with the inner wall of the second oblong hole 20. The bolt head of the second limiting bolt 22 slides in engagement with the end of the first support block 13 away from the fifth support beam 5. The first support block 13 is limited and slidably connected to the fifth support beam 5 through the second limiting bolt 22 and the second oblong hole 20, thereby realizing the limited and slidable connection between the first support block 13 and the fifth support beam 5.

[0115] In this embodiment, refer to Figure 4 The number of second limiting bolts 22 can be two, which can further improve the stability of the limiting sliding connection between the first support block 13 and the fifth support beam 5.

After the adjustment is completed, tighten the second limiting bolt 22 to re-fix the first support block 13 and the fifth support beam 5.

[0133] Next, loosen the first limiting bolt 21, adjust the horizontal position of the second support block 14, and after adjustment, retighten the first limiting bolt 21 to re-fix the second support block 14 and the first support block 13.

[0134] Next, refer to Figure 10 The handheld welding clamp 23 is placed on the second support block 14, and a pressure block 15 is installed on the second support block 14 to fix the handheld welding clamp 23. When the handheld welding clamp 23 is installed on this fixture, the second lead screws 19 located on both sides can be turned simultaneously to adjust the height of the handheld welding clamp 23.

[0135] Next, refer to Figure 10 The side fixing bolts 16 are screwed into the second support block 14 and the side fixing bolts 16 are made to abut against the handheld welding clamp 23, thereby further fixing the handheld welding clamp 23.

[0136] Finally, refer to Figure 8 , Figure 9 or Figure 11Place the stringer 24 on the guide groove 9, and then place the reinforcing plate 25 on the stringer 24. After placement, press the bottom end of the stringer 24 and the top end of the reinforcing plate 25 with the upper and lower electrodes of the hand-held welding clamp 23 to complete the welding of the stringer 24 and the reinforcing plate 25. When it is necessary to weld the reinforcing plate 25 to different positions on the stringer 24, simply slide the stringer 24 within the guide groove 9 to weld the reinforcing plate 25 to different positions on the stringer 24. Therefore, the welding process is convenient and quick, improving welding efficiency.
