Description

Technical Field

[0001] This utility model relates to the field of shipbuilding and repair technology, specifically to a pipe welding positioning fixture used in shipbuilding and repair. Background Technology

[0002] In the shipbuilding and repair industry, the installation and welding of piping systems are crucial processes. Ship piping is typically long, requiring the connection and welding of multiple sections on-site. To ensure uniform and reliable weld quality, all-position welding is usually necessary for pipe welding operations in shipbuilding and repair. Currently, the commonly used welding method involves operators moving around a fixed pipe. This method has significant drawbacks: welding is inconvenient and inefficient, requiring operators to constantly adjust their position and welding posture to complete the welding of the entire pipe. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pipe welding positioning fixture for ship repair and construction, so as to solve the technical problems of inconvenient and inefficient pipe welding operations in ship repair and construction.

[0004] To solve the above-mentioned technical problems, this utility model provides a pipe welding positioning fixture for ship repair and construction, comprising: Base; The movable seat and the fixed seat are slidably connected to the base in the left and right direction. The fixed seat is fixedly connected to the base and located on the right side of the movable seat. Both the movable seat and the fixed seat have through holes in the left and right direction and the two through holes are coaxially arranged. Two clamping components are rotatably connected in the through holes of the movable base and the fixed base, respectively. Both clamping components are provided with mounting slots for clamping the pipes. The positions of the two mounting slots correspond to each other so that the two clamped pipes are coaxially arranged. The drive assembly and the transmission assembly drive the two clamping assemblies to rotate synchronously through the transmission assembly. Fixing components are used to secure the movable base to the base.

[0005] With the above structure, the pipe welding positioning fixture for ship repair and construction of this utility model has the following advantages: the two pipes to be welded are fixed in two clamping components respectively, and then the sliding seat is slid to make the two pipes contact and the fixing component is used to fix the sliding seat to the base. After the operator welds a section in the circumferential direction, the driving component drives the two clamping components to rotate through the transmission component, which drives the two pipes to rotate so that the unwelded part faces the operator. The operator does not need to adjust his own position and welding posture, making the operation more convenient and improving the welding efficiency. Moreover, the two pipes are made to contact by the sliding seat after the pipes are installed, ensuring that the two pipes are in contact and making the operation more convenient.

[0006] As an improvement, the clamping assembly includes a mounting base, a fixing block, and a first fixing bolt. The mounting base is rotatably connected to the through hole, and the mounting groove is located in the mounting base and extends through the mounting base in the left-right direction. The fixing block is slidably connected to the mounting groove in the vertical direction. The first fixing bolt is threaded onto the mounting base, and the lower end of the first fixing bolt is rotatably connected to the fixing block. By rotating the first fixing bolt, the pipeline is clamped between the fixing block and the bottom of the mounting groove. With this structure, through the cooperation of the mounting base, the fixing block, and the first fixing bolt, a simple and convenient clamping solution is provided. Rotating the first fixing bolt drives the fixing block to move up and down, thereby firmly pressing the pipeline against the bottom of the mounting groove, realizing the rapid clamping and loosening of the pipeline. Moreover, the clamping force is adjustable, which can effectively prevent the pipeline from slipping or shifting during rotary welding, ensuring the stability of the welding process.

[0007] As an improvement, both the bottom of the mounting groove and the bottom of the fixing block have two symmetrically arranged inclined surfaces along the front-back direction. The distance between the upper ends of the two inclined surfaces at the bottom of the mounting groove is greater than the distance between the lower ends, and the distance between the lower ends of the two inclined surfaces at the bottom of the fixing block is greater than the distance between the upper ends. With this structure, by setting the bottom of the mounting groove and the bottom of the fixing block as symmetrical inclined surfaces, the clamping component can adaptively clamp circular pipes of different diameters. When the first fixing bolt is tightened, the fixing block presses down, and its inclined surface and the inclined surface at the bottom of the mounting groove together form a gradually narrowing wedge-shaped space, which can fit well against the outer circle of the pipe, thereby increasing the contact area, improving the stability and reliability of clamping, and effectively preventing the pipe from being deformed or rotated under pressure.

[0008] As an improvement, each inclined surface is connected to a rubber pad; with this structure, the addition of rubber pads on the inclined surfaces further enhances the clamping effect. On the one hand, the rubber pads increase the friction with the pipe surface, further preventing slippage; on the other hand, their soft texture can protect the pipe surface from being pinched or scratched.

[0009] As an improvement, the transmission assembly includes a telescopic rod, two first gears, and two second gears. The drive assembly includes a drive motor connected to the base. The two ends of the telescopic rod are rotatably mounted on a movable seat and a fixed seat, respectively. The telescopic rod is equipped with two first gears. A portion of the mounting seat protrudes outside the through hole and is equipped with a second gear that meshes with the first gears. The drive motor drives the telescopic rod to rotate. With this structure, the transmission scheme is compact and precise. The gear meshing ensures that power is efficiently and synchronously transmitted to the two mounting seats, thereby driving the two pipes to rotate precisely and synchronously, avoiding the problem of asynchronous welding. The design of the telescopic rod cleverly combines the transmission with the sliding adjustment function of the movable seat, allowing the transmission link to remain effectively connected when the movable seat is adjusted.

[0010] As an improvement, both the movable seat and the fixed seat are connected to connecting seats. The telescopic rod includes an outer rod and an inner rod. The outer rod is rotatably connected to the connecting seat on the movable seat, and the inner rod is rotatably connected to the connecting seat on the fixed seat. The inner rod is slidably connected inside the outer rod. The inner wall of the outer rod is provided with a limiting groove, and the outer wall of the inner rod is provided with a protrusion that is slidably connected inside the limiting groove. With this structure, it is ensured that while the inner rod extends and retracts relative to the outer rod to adapt to the position change of the movable seat, the torque can be effectively transmitted from the inner rod to the outer rod. This avoids transmission failure caused by relative rotation between the inner and outer rods, and ensures the reliability and stability of power transmission.

[0011] As an improvement, the inner wall of the outer rod is provided with two limiting grooves along the circumference, and the outer wall of the inner rod is provided with two protrusions along the circumference. With this structure, by setting two symmetrical limiting grooves and protrusions, the force on the telescopic rod is more balanced, effectively preventing jamming or uneven wear that may occur due to single-point force, and further improving the smoothness of the transmission process and the service life of the telescopic rod.

[0012] As an improvement, the fixing component includes two limiting blocks and two second fixing bolts. The two limiting blocks are spaced apart on the base, and the movable seat is slidably connected between the two limiting blocks. Each limiting block has a through groove arranged in the left-right direction. The two second fixing bolts pass through the two through grooves and are threadedly connected to the movable seat. With this structure, the movable seat can be easily locked after being adjusted to the correct position by using the two limiting blocks with through grooves and the second fixing bolts. Tightening the second fixing bolts will firmly fix the movable seat on the base. The structure is simple and easy to operate, ensuring the rigidity of the entire tooling system during welding and avoiding the impact of the movable seat displacement on the welding accuracy.

Both the movable seat 2 and the fixed seat 3 have through holes 4 in the left-right direction, and the two through holes 4 are coaxially arranged. It should be noted that the left-right direction in this utility model is the length direction of the base 1, and the front-back direction is the width direction of the base 1.

[0019] The fixing component 8 is used to fix the movable base 2 to the base 1, such as... Figure 1 As shown, the fixing component 8 includes two limiting blocks 81 and two second fixing bolts 82. The two limiting blocks 81 are spaced apart on the base 1 in the front and back direction. The movable seat 2 is slidably connected between the two limiting blocks 81.

The two second fixing bolts 82 pass through the two through grooves 14 respectively and are threadedly connected to the movable seat 2.

[0020] Two clamping components 5 are rotatably connected to the through holes 4 of the movable base 2 and the fixed base 3, respectively. Each clamping component 5 is provided with a mounting groove 6 for clamping the pipes. The positions of the two mounting grooves 6 correspond to each other, ensuring that the two clamped pipes are coaxially arranged. Specifically, as shown... Figure 1 and Figure 3 As shown, the clamping assembly 5 includes a mounting base 51, a fixing block 52, and a first fixing bolt 53. The mounting base 51 is rotatably connected to the through hole 4. The mounting groove 6 is located in the mounting base 51 and extends through the mounting base 51 in the left-right direction. The fixing block 52 is slidably connected to the mounting groove 6 in the vertical direction. The first fixing bolt 53 is threadedly connected to the mounting base 51, and the lower end of the first fixing bolt 53 is rotatably connected to the fixing block 52. By rotating the first fixing bolt 53, the pipeline is clamped between the fixing block 52 and the bottom of the mounting groove 6.

[0021] like Figure 3 As shown, the bottom of the mounting groove 6 and the bottom of the fixing block 52 are both two inclined surfaces symmetrically arranged in the front-back direction. The distance between the upper ends of the two inclined surfaces at the bottom of the mounting groove 6 is greater than the distance between the lower ends, and the distance between the lower ends of the two inclined surfaces at the bottom of the fixing block 52 is greater than the distance between the upper ends. The two inclined surfaces of the mounting groove 6 of one mounting base 51 are coplanar with the two inclined surfaces of the mounting groove 6 of the other mounting base 51, thereby achieving the centering installation of the pipeline. In addition, a rubber pad 9 is connected to each inclined surface.

[0022] The drive assembly drives the two clamping assemblies 5 to rotate synchronously via the transmission assembly 7, such as... Figure 1 As shown, the transmission assembly 7 includes a telescopic rod 71, two first gears 72 and two second gears 73. The drive assembly includes a drive motor 10 connected to the base 1. The two ends of the telescopic rod 71 are rotatably mounted on the movable seat 2 and the fixed seat 3, respectively. The telescopic rod 71 is provided with two first gears 72. A part of the mounting seat 51 is exposed outside the through hole 4 and is provided with a second gear 73 that meshes with the first gears 72. The drive motor 10 drives the telescopic rod 71 to rotate.

[0023] Both the movable seat 2 and the fixed seat 3 are connected to a connecting seat 11. The connecting seat 11 can be integrally formed with the movable seat 2 and the fixed seat 3 or fixedly connected by bolts. The telescopic rod 71 includes an outer rod 711 and an inner rod 712. The outer rod 711 is rotatably connected to the connecting seat 11 on the movable seat 2, and the inner rod 712 is rotatably connected to the connecting seat 11 on the fixed seat 3. The inner rod 712 is slidably connected to the outer rod 711. The inner wall of the outer rod 711 is provided with a limiting groove 12, and the outer wall of the inner rod 712 is provided with a protrusion 13 slidably connected to the limiting groove 12. In this embodiment, the inner wall of the outer rod 711 is provided with two limiting grooves 12 along the circumference, and the outer wall of the inner rod 712 is provided with two protrusions 13 along the circumference. The limiting groove 12 can be either penetrating through the outer wall of the outer rod 711 or not penetrating through the outer wall of the outer rod 711. In this embodiment, the limiting groove 12 penetrates through the outer wall of the outer rod 711.

[0024] The two pipes to be welded are fixed in the two clamping components 5 respectively. Then, the sliding seat 2 is slid to make the two pipes contact and the fixing component 8 is used to fix the sliding seat 2 to the base 1. After the operator welds a section in the circumferential direction, the driving component drives the two clamping components 5 to rotate through the transmission component 7, which drives the two pipes to rotate so that the unwelded part faces the operator. The operator does not need to adjust his own position and welding posture, making the operation more convenient and improving the welding efficiency. Moreover, the two pipes are made to contact by the sliding seat 2 after the pipes are installed, ensuring that the two pipes are in contact and making the operation more convenient.
