Description

Technical Field

[0001] The utility model relates to the technical field of rigging, in particular to a bending limit mechanism for rigging processing. Background Technique

[0002] A rigging is a device used for connecting, fixing, and bearing loads, and is widely used in fields such as construction, transportation, ships, mines, etc. Its shapes and sizes are diverse, including hooks, rings, eyebolts, wire rope clips, etc. Bending processing can not only change the shape of the rigging to adapt to different usage requirements, but also improve the structural strength of the rigging.

[0003] During the bending process of rigging, stability is a key factor. If the rigging moves or slides during the bending process, it will lead to inaccurate bending angles, affecting the quality and safety of the final product. Therefore, during the bending process, a limit mechanism is needed to fix the rigging to ensure its stability and accuracy during processing. Currently, there are some obvious defects in the existing bending limit mechanisms for rigging processing on the market. For example, many existing limit mechanisms use split-type fixation. This method only "holds" the rigging, and the fixation is not firm enough, easily loosening during the processing, resulting in the displacement of the rigging and affecting the bending accuracy.

[0004] Therefore, there is an urgent need for a bending limit mechanism for rigging processing to solve the technical defects mentioned in the above technology. Content of the Utility Model

[0005] The purpose of the utility model is to provide a bending limit mechanism for rigging processing to solve the problems of loose limitation and rigging movement during processing mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A bending limit mechanism for rigging processing, including a bottom plate and a limit seat. A set of limit seats are arranged on the left and right sides of the top of the bottom plate. A through groove is opened in the limit seat. A straight groove is opened at the top of the clamping side of the limit seat. Two sets of movable blocks are respectively embedded in the limit seat. The movable blocks are embedded in the through groove. A convex block is integrally arranged at the top of the movable block. The convex block is embedded in the straight groove. The limit seat and the movable block form a movable connection. Side grooves are respectively opened on the inner side walls of the movable blocks. A moving block is arranged between the two movable blocks on the same side. Convex steps are respectively processed on the surface of the moving block close to the movable block. The convex steps are embedded in the side grooves for movement. A set of motor seats are arranged on both sides of the top of the bottom plate.

[0007] Preferably, drive motors are respectively fixedly connected to the motor seats. The output shafts of the drive motors are fixedly connected with linear screws. Inner grooves are respectively opened in the moving blocks. Threaded sleeves are respectively sleeved on the outer parts of the linear screws. The threaded sleeves are welded to the other side of the moving block.

[0008] Preferably, fixing holes are respectively formed in the limiting seats, and fixing bolts are fixedly connected between the motor bases and the limiting seats.

[0009] Preferably, the cross section of the movable block is a right trapezoid, and the cross section of the moving block is an isosceles trapezoid.

[0010] Preferably, limiting blocks are fixedly connected to the clamping sides of the movable blocks, and angle bolts and side bolts are fixedly connected between the limiting blocks and the movable blocks.

[0011] Preferably, a set of adjusting rods are fixedly connected to the front and rear ends of the bottom plate respectively. Sleeve is sleeved outside the adjusting rod, connecting frames are welded at the sleeves, the other ends of the connecting frames are welded to the limiting seats, adjusting holes are formed in the adjusting rods, and locking bolts are fixedly connected between the adjusting holes and the sleeves respectively.

[0012] Preferably, there are multiple groups of the adjusting holes, and the adjusting holes are arranged at equal intervals in the adjusting rods.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: The bending limiting mechanism for rigging processing not only realizes more precise and rigorous limiting, avoids the movement of the rigging during processing, realizes the need not to fix manually, improves the bending precision, reduces the manual error, but also realizes the adaptation to riggings of different sizes, and has highly flexible adjustability;

[0014] (1) By providing a driving motor, a linear screw, a moving block, a convex step, a movable block, a side groove, and a straight groove, the limiting mechanism takes the bottom plate as the installation table surface. When clamping the rigging, the driving motor drives the linear screw to rotate, thereby pushing the threaded sleeve to horizontally move towards the clamping side, that is, the central position of the bottom plate, thereby driving the moving block to move. When the moving block moves, the convex steps at both ends of its outer wall tightly abut against the side grooves on the inner wall of the movable block, pushing the two groups of side grooves to open outwards. Due to the limitation of the straight groove, the movable block can only move linearly, thereby opening the two groups of limiting blocks. When the threaded sleeve retracts, the movable block moves back under the pulling of the moving block, and the two limiting blocks on the same side clamp the rigging. Thus, through the fixation of the rigging by the four groups of limiting blocks, more precise and rigorous limiting is realized, and the movement of the rigging during processing is avoided;

[0015] (2) By providing a driving motor, a linear screw, a threaded sleeve, and a moving block, the device drives the linear screw to rotate through the driving motor, and the movement of the threaded sleeve drives the moving block to move back and forth, thereby realizing the limiting of the rigging. By controlling the rotation speed of the driving motor, a fine micro-movement distance can be realized, and better clamping effect can also be achieved for riggings with smaller sizes. There is no need to fix manually, the bending precision is improved, and the manual error is reduced;

[0016] (3) By setting up the finite position seats, connecting frames, adjusting rods, limit type blocks, side bolts, and locking bolts, both groups of finite position seats are fixed to the adjusting rods through the connecting frames. If dealing with riggings of different sizes, the locking bolts can be unlocked to move the positions of the finite position seats. Moreover, the limit type blocks can also be disassembled from the movable blocks through the side bolts and corner bolts, facilitating the replacement of different limit type blocks, thus adapting to riggings of different sizes and having highly flexible adjustability.

Detailed Embodiment

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1: Please refer to Figures 1-4, A bending limit mechanism for rigging processing, including a bottom plate 1 and a limit seat 6. On the top of the bottom plate 1, a set of limit seats 6 are arranged on each of the left and right sides. A through groove 21 is opened in the limit seat 6, and a straight groove 16 is opened at the top of the clamping side of the limit seat 6. Two sets of movable blocks 13 are respectively embedded in the limit seat 6. The movable blocks 13 are embedded in the through groove 21. A convex block 17 is integrally arranged on the top of the movable block 13. The convex block 17 is embedded in the straight groove 16. The limit seat 6 and the movable block 13 form a movable connection. Side grooves 20 are respectively opened on the inner side walls of the movable blocks 13. A moving block 23 is arranged between the two movable blocks 13 on the same side. Convex steps 19 are respectively machined on the surfaces of the moving block 23 close to the movable blocks 13. The convex steps 19 are embedded in the side grooves 20 for movement. A set of motor seats 8 are arranged on each of the two sides at the top of the bottom plate 1. The cross section of the movable block 13 is a right trapezoid, and the cross section of the moving block 23 is an isosceles trapezoid;

[0024] Specifically, as Figure 1 , Figure 2 and Figure 4 shown, the limit mechanism uses the bottom plate 1 as the installation tabletop. When clamping the rigging, the driving motor 9 drives the linear screw 10 to rotate, thereby pushing the threaded sleeve 11 to move horizontally towards the clamping side, that is, the center position of the bottom plate 1, thereby driving the moving block 23 to move. When the moving block 23 moves, the convex steps 19 at both ends of its outer wall tightly abut against the side grooves 20 on the inner wall of the movable block 13, pushing the two side grooves 20 to open outwards. Due to the limitation of the straight groove 16, the movable block 13 can only move in a straight line, thereby opening the two limit blocks 15. When the threaded sleeve 11 retracts, the movable block 13 moves back under the pull of the moving block 23, and the two limit blocks 15 on the same side clamp the rigging, thereby fixing the rigging through the four limit blocks 15.

[0025] Embodiment 2: Driving motors 9 are respectively fixedly connected to the motor seats 8. The output shafts of the driving motors 9 are fixedly connected with linear screws 10. Inner grooves 12 are respectively opened in the moving blocks 23. Threaded sleeves 11 are respectively sleeved on the outer parts of the linear screws 10. The threaded sleeves 11 are welded to the other side of the moving blocks 23;

[0026] Specifically, as Figure 1 and Figure 4 shown, the device drives the linear screw 10 to rotate through the driving motor 9, and the movement of the threaded sleeve 11 drives the moving block 23 to move back and forth, thereby realizing the limitation of the rigging. By controlling the rotation speed of the driving motor 9, a fine micro-movement distance can be achieved.

[0027] Embodiment 3: Fixing holes 7 are respectively formed in the limit seats 6. Fixing bolts 22 are respectively and fixedly connected between the motor seats 8 and the limit seats 6. Limiting blocks 15 are fixedly connected to the clamping sides of the movable blocks 13. Angle bolts 18 and side bolts 14 are fixedly connected between the limiting blocks 15 and the movable blocks 13. A set of adjusting rods 2 are fixedly arranged at the front and rear ends of the bottom plate 1. Sleeve 4 are sleeved outside the adjusting rods 2. Connecting frames 5 are welded at the positions of the sleeves 4. The other ends of the connecting frames 5 are welded to the limit seats 6. Adjusting holes 24 are formed in the adjusting rods 2. Locking bolts 3 are respectively and fixedly connected between the adjusting holes 24 and the sleeves 4. Multiple groups of adjusting holes 24 are provided, and the adjusting holes 24 are arranged at equal intervals in the adjusting rods 2;

[0028] Specifically, as Figure 1 and Figure 2 shown, both groups of limit seats 6 are fixed to the adjusting rods 2 through the connecting frames 5. If riggings of different sizes are to be clamped, the locking bolts 3 can be unlocked to move the positions of the limit seats 6, and the limiting blocks 15 can also be disassembled from the movable blocks 13 through the side bolts 14 and the angle bolts 18.

[0029] Working principle: The limiting mechanism uses the bottom plate 1 as the installation tabletop. When clamping a rigging, the driving motor 9 drives the linear screw rod 10 to rotate, thereby pushing the threaded sleeve 11 to horizontally move towards the clamping side, that is, the center position of the bottom plate 1, so as to drive the movable block 23 to move. When the movable block 23 moves, the convex steps 19 at both ends of its outer wall tightly abut against the side grooves 20 on the inner wall of the movable block 13, pushing the two groups of side grooves 20 to open outwards. Due to the limitation of the straight grooves 16, the movable block 13 can only move linearly, so as to open the two groups of limiting blocks 15. When the threaded sleeve 11 retracts, the movable block 13 moves back under the pull of the movable block 23, and the two limiting blocks 15 on the same side clamp the rigging, so as to fix the rigging through the four groups of limiting blocks 15.
