Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, specifically to a structural support rod clamping fixture for shipbuilding. Background Technology

[0002] With the rapid development of the shipbuilding industry, assembly and construction methods are constantly being updated. However, the traditional method of using profile welding for temporary fixation has significant drawbacks. This method requires welding profiles to the assembled parts, and after construction, the profiles need to be cut, and the welded areas need to be ground and repainted. The operation process is cumbersome and inefficient. In addition, the profiles have low reusability and poor adjustability, making it difficult to adapt to the fixation requirements of parts of different sizes or shapes, resulting in increased construction costs, extended construction periods, and increased operational difficulty. These problems have made the demand for more efficient, flexible, and reusable fixation fixtures increasingly urgent.

[0003] Chinese Patent Publication No. CN222371462U discloses a tooling for a structural support rod clamp. This device uses clamps at both ends of the support rod to fix assembled parts. The clamp body has a U-shaped mounting groove, and the movable part can slide along the side wall to clamp or release the parts. When the movable part is pressed down, its inclined driving surface pushes the pin backward to compress the spring; after release, the spring returns to its original position, causing the pin to engage with the locking groove of the movable part and lock its position. The support rod adopts a three-section threaded structure, and the length of the sleeves at both ends can be adjusted synchronously by rotating the central handle to adapt to different spacing requirements. The connecting device uses a rotatable locking ring, allowing the clamp to be flexibly adjusted in angle. However, this device mainly uses the movable part and the pin to clamp the workpiece. The side wall of the movable part has slots for the pin to be inserted. When there are more slots, the adjustability of the movable part increases but the stability decreases. When there are fewer slots, the adjustability of the movable part decreases but the stability increases. Therefore, this fixing method has significant limitations.

[0004] Therefore, the present invention aims to provide a structural support rod clamping fixture for shipbuilding to solve the above problems. Utility Model Content

[0005] To address the aforementioned problems, a structural support rod clamping fixture for shipbuilding is provided. This fixture employs a clamping structure with clamps connected to both ends of the support rod. The clamp body features a movable through groove and a threaded adjustment mechanism. Rotating the handle drives the threaded rod, which in turn moves the abutment block linearly. Four corner limit rods, engaging with slots, prevent rotation, achieving stable clamping. This solves the problem of significant limitations in existing fixing methods.

[0006] To address the problems of existing technologies, this utility model provides a structural support rod clamping fixture for shipbuilding, including a support rod. Connecting devices are provided at both ends of the support rod, and a clamp is provided at the other end of each connecting device. The clamp includes a clamp body with a movable through groove. A threaded through hole is provided on the side wall of the movable through groove, and a threaded rod is threadedly connected to the threaded through hole. An abutment block is installed at the bottom of the threaded rod, and limiting rods are provided at the four corners of the abutment block. A limiting slot adapted to the limiting rod is provided on the clamp body. A limiting block is provided at the end of the limiting rod away from the abutment block, and a through hole for the threaded rod to pass through is provided on the limiting block. A rotating handle is provided at the end of the threaded rod away from the abutment block.

[0007] Preferably, the chuck body is covered with a reinforcing plate to enhance its strength.

[0008] Preferably, a gasket is installed at the end of the movable through slot away from the threaded through hole.

[0009] Preferably, the limiting block has several threaded holes at equal angles around the through hole, and the rotating handle has a through hole that matches the threaded holes; when the abutment block presses against the workpiece, the bolt is passed through the through hole and screwed into the threaded hole to fix the position of the abutment block.

[0010] Preferably, the support rod includes a first connecting rod and a second connecting rod. The end of the first connecting rod away from the clamp is provided with a mounting slot, and the end of the second connecting rod away from the clamp is provided with a mounting insert adapted to the mounting slot. The mounting insert is provided with a plurality of fixing slots, and the side wall of the mounting slot is provided with a through groove adapted to the fixing slot.

[0011] Preferably, the side wall of the mounting slot is provided with a guide groove, and the side wall of the mounting rod is provided with a guide block adapted to the guide groove; when the mounting rod is inserted into the mounting slot, the guide block is inserted into the guide groove.

[0012] Preferably, an extension component is provided between the first connecting rod and the second connecting rod. One end of the extension component is provided with a mounting rod adapted to the mounting slot, and the other end of the extension component is provided with a mounting slot adapted to the mounting rod.

[0013] Preferably, after the bolt passes through the through groove and the fixing slot, the bolt position is fixed by a nut.

[0014] The advantages of this utility model compared to the prior art are:

[0015] 1. In this utility model, the continuous linear movement of the abutment block is achieved through the cooperative design of the threaded rod and the limiting rod, which solves the problems of limited adjustability or insufficient limiting effect of traditional pin-type chucks. The limiting rods distributed at the four corners and the limiting slots form a double constraint, which not only prevents the abutment block from rotating, but also ensures that the clamping force is transmitted vertically, thereby improving clamping stability and accuracy.

[0016] 2. In this utility model, the support rod adopts a modular plug-in structure. Multi-level length adjustment is achieved through the cooperation of the mounting slot, plug rod, and guide block, solving the problem of poor adaptability of traditional fixed-length support rods. The bolt locking mechanism of the fixed slot and the through slot, combined with the axial alignment function of the guide slot, ensures both adjustment flexibility and enhanced connection rigidity, making it suitable for the clamping needs of complex spatial structures in shipbuilding.

[0017] 3. In this utility model, the combined design of the reinforcing plate, the washer, and the bolt-nut locking structure effectively disperses the clamping load and suppresses the impact of vibration. The reinforcing plate enhances the deformation resistance of the chuck, the washer buffers the impact at the end, and the bolt locks the threaded rod to prevent backing. The three components work together to solve the defects of traditional clamps that are prone to loosening and wear under dynamic working conditions, significantly improving the reliability and service life of the tooling.

[0025] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0026] Reference Figures 1-6 As shown: A structural support rod fixture for shipbuilding includes a support rod 1. Connecting devices 2 are provided at both ends of the support rod 1. A chuck 3 is provided at the other end of each connecting device 2. The chuck 3 includes a chuck body 4. A movable through groove 5 is provided on the chuck body 4. A threaded through hole 6 is provided on the side wall of the movable through groove 5. A threaded rod 7 is threadedly connected to the threaded through hole 6. An abutment block 8 is installed at the bottom of the threaded rod 7. Limiting rods 9 are provided at the four corners of the abutment block 8. A limiting slot 10 adapted to the limiting rod 9 is provided on the chuck body 4. A limiting block 11 is provided at the end of the limiting rod 9 away from the abutment block 8. A through hole for the threaded rod 7 to pass through is provided on the limiting block 11. A rotating handle 12 is provided at the end of the threaded rod 7 away from the abutment block 8.

[0027] In the prior art, the chuck 3 relies on the cooperation of a pin and a movable block to clamp the workpiece. The movable block has slots for the pin to be inserted, and the slots are equidistant. However, too many slots will weaken the pin's limiting effect, while too few slots will weaken the adjustability of the movable block. To solve this problem, in this application, the support rod 1 serves as the main frame and is connected to the chuck 3 through the connecting devices 2 at both ends, thereby transferring the clamping function to the target workpiece. The movable through slot 5 on the chuck body 4 provides space for the linear movement of the abutment block 8. When the operator rotates the rotating handle 12 at the end of the threaded rod 7, the threaded rod 7 undergoes axial displacement in the threaded through hole 6 on the side wall of the chuck body 4. At this time, the abutment block 8, which is fixed to the bottom of the threaded rod 7, can only translate along the direction of the limiting slot 10 under the constraint of the limiting rod 9, avoiding the problem of the abutment block 8 rotating due to the rotation of the threaded rod 7.

[0028] The design of the limiting rod 9 and the limiting slot 10 ensures the stability of the clamping process. The limiting rods 9, distributed at the four corners, form a double limiting structure through the limiting blocks 11 at their ends. This not only restricts the movement trajectory of the abutment block 8 but also allows the threaded rod 7 to pass freely through the through hole, achieving effective force transmission. As the threaded rod 7 advances, the abutment block 8 gradually presses against the workpiece surface, achieving clamping and fixation through friction and contact pressure. The connecting device 2 plays a role in force distribution and support during this process, enabling the chuck 3 to adapt to different installation angles or workpiece shapes, ultimately achieving reliable clamping of complex structures in shipbuilding.

[0029] Reference Figure 2 and Figure 3 As shown: The clamp body 4 is wrapped with a reinforcing plate 13 to enhance the strength of the clamp body 4.

[0030] The reinforcing plate 13 is wrapped around the outside of the chuck body 4 and fixed by welding or bolts to form a composite structure. Its core function is to improve the overall rigidity and deformation resistance of the chuck body 4. During the clamping process, when the threaded rod 7 applies pressure by rotating the handle 12, the chuck body 4 needs to withstand the reaction force from the abutment block 8 and the reaction load from the workpiece. By covering the key stress areas of the chuck body 4, the reinforcing plate 13 disperses local stress concentration and avoids deformation or cracking of the chuck body 4 due to high-intensity clamping or long-term use.

[0031] Reference Figure 2 and Figure 3 As shown: A gasket 14 is installed at the end of the movable through groove 5 away from the threaded through hole 6.

[0032] The gasket 14 is fixed to the end of the movable through groove 5 away from the threaded through hole 6. Its core function is to buffer the impact on the workpiece when it is fixed.

[0033] Reference Figure 2 and Figure 3 As shown: The periphery of the through hole of the limiting block 11 is provided with a plurality of threaded holes 15 at equal angles, and the rotating handle 12 is provided with a through hole that matches the threaded holes 15.

[0034] When the abutment block 8 presses against the workpiece, the bolt is passed through the through hole and screwed into the threaded hole 15 to fix the position of the abutment block 8.

[0035] The threaded holes 15, evenly distributed around the through hole of the limiting block 11, are aligned with the corresponding through holes on the rotating handle 12. After the abutment block 8 is tightened and presses the workpiece by the threaded rod 7, the operator passes the bolt through the through hole of the rotating handle 12 and screws it into the threaded hole 15 of the limiting block 11, thus achieving a rigid connection between the threaded rod 7 and the limiting block 11. This design, through the engagement of the bolt and the threaded hole 15, instantly locks the originally freely rotating threaded rod 7, eliminating the risk of accidental retraction of the threaded rod 7 due to external vibration or workpiece reaction force, thereby maintaining a constant clamping force.

[0036] Reference Figures 1-6 As shown: The support rod 1 includes a first connecting rod 16 and a second connecting rod 17. The end of the first connecting rod 16 away from the clamp 3 is provided with a mounting slot 18. The end of the second connecting rod 17 away from the clamp 3 is provided with a mounting insert 19 that is adapted to the mounting slot 18. The mounting insert 19 is provided with a plurality of fixing slots 20. The side wall of the mounting slot 18 is provided with a through groove 21 that is adapted to the fixing slot 20.

[0037] The first connecting rod 16 and the second connecting rod 17 are length-adjustable through the cooperation of the mounting slot 18 and the mounting rod 19: the mounting rod 19 at the end of the second connecting rod 17 is inserted into the mounting slot 18 of the first connecting rod 16 to form a sliding pair, allowing the overall length of the support rod 1 to be flexibly extended and retracted according to clamping requirements. Several fixed slots 20 spaced apart on the mounting rod 19 and the through groove 21 on the side wall of the mounting slot 18 form a position locking channel. When adjusted to the target length, the operator can rigidly connect the first connecting rod 16 and the second connecting rod 17 by inserting a pin or bolt through the through groove 21 and the corresponding fixed slot 20, preventing the support rod 1 from sliding relative to each other when under force.

[0038] Reference Figures 4-6 As shown: The mounting slot 18 has a guide groove 22 on its side wall, and the mounting rod 19 has a guide block 23 on its side wall that is adapted to the guide groove 22;

[0039] When the mounting rod 19 is inserted into the mounting slot 18, the guide block 23 is inserted into the guide groove 22.

[0040] The guide groove 22 on the side wall of the mounting slot 18 and the guide block 23 on the side wall of the mounting rod 19 form a complementary contour match. When the mounting rod 19 is inserted into the mounting slot 18, the guide block 23 slides in along the path of the guide groove 22, forcibly guiding the mounting block to axially align with the mounting slot 18. This eliminates the need for manual angle adjustment and ensures that the mounting rod 19 always moves along the preset trajectory during insertion. This avoids scratches on the inner wall of the mounting slot 18 or jamming of the mounting block due to skew, significantly improving assembly efficiency.

[0041] Reference Figures 4-6 As shown: An extension component 24 is provided between the first connecting rod 16 and the second connecting rod 17. One end of the extension component 24 is provided with a mounting rod 19 that is adapted to the mounting slot 18, and the other end of the extension component 24 is provided with a mounting slot 18 that is adapted to the mounting rod 19.

[0042] When the support rod 1 needs to be further extended, the operator inserts the mounting rod 19 of the extension component 24 into the mounting slot 18 of the first connecting rod 16, and at the same time inserts the mounting rod 19 of the second connecting rod 17 into the mounting slot 18 at the other end of the extension component 24, so as to achieve a stepped extension of the total length of the support rod 1 through multi-level insertion.

[0043] Reference Figures 4-6 As shown: After the bolt passes through the through groove 21 and the fixing slot 20, the bolt position is fixed by the nut.

[0044] After the first connecting rod 16 and the second connecting rod 17 are adjusted to the target length through the mounting slot 18 and the mounting rod 19, the bolts pass through the through groove 21 on the side wall of the first connecting rod 16 and the reserved hole in the fixing slot 20 of the second connecting rod 17 in sequence, and finally the two connecting rods are pressed and fixed by tightening the nut.

[0045] Working principle: The support rod 1 serves as the main frame, with both ends connected to the chuck 3 via connecting devices 2. The chuck body 4 has a movable through groove 5, and the threaded rod 7 passes through the threaded through hole 6 on the side wall and is fixed to the abutment block 8 at the bottom. When the operator rotates the rotating handle 12 at the end of the threaded rod 7, the threaded rod 7 drives the abutment block 8 to move linearly along the movable through groove 5. The limiting rods 9 at the four corners of the abutment block 8 are inserted into the limiting slots 10 of the chuck body 4, and the rotation is restricted by the limiting blocks 11, ensuring that the abutment block 8 only moves in a straight line, thereby pressing the workpiece surface to achieve clamping. The connecting device 2 transmits the clamping force to the support rod 1 and adapts to different workpiece angles.

[0046] The reinforcing plate 13 encasing the main body 4 enhances overall rigidity through a composite structure, dispersing the reaction force generated during clamping and preventing deformation of the main body. The gasket 14 installed at the end of the movable through-slot 5 uses elastic or wear-resistant material to buffer the impact when the abutment block 8 moves to its limit position, reducing metal wear and noise. Threaded holes 15 are equally angled around the through hole of the limiting block 11, corresponding to the through hole of the rotating handle 12. After the abutment block 8 clamps the workpiece, a bolt is inserted and screwed into the threaded hole 15 to lock the threaded rod 7 in position, preventing vibration from causing the clamp to loosen.

[0047] The support rod 1 consists of a first connecting rod 16 and a second connecting rod 17. Its length is adjusted by interlocking with the mounting slot 18 and the mounting rod 19. The fixing slot 20 on the mounting rod 19 is aligned with the through groove 21 on the side wall of the mounting slot 18, and a fixing element is inserted to lock the length. The guide groove 22 on the side wall of the mounting slot 18 cooperates with the guide block 23 on the mounting rod 19 to ensure axial alignment during insertion and prevent misalignment or jamming. An extension component 24 can be inserted between the first and second connecting rods 17. This component has mounting slots 18 and mounting rods 19 at both ends, further extending the support rod 1 through multi-stage interlocking. After the bolt passes through the through groove 21 and the fixing slot 20, the connecting rod is tightened by a nut. The shear resistance of the bolt and the preload of the nut maintain a rigid connection, resisting clamping loads and vibrations.

[0048] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
