Description

Technical Field

[0001] This invention relates to the field of metal material processing technology, and in particular to a cutting clamp for hardware rigging. Background Technology

[0002] Rigging refers to the force-bearing tools used to move objects between lifting machinery and the object being lifted, as well as the force-bearing components used to stabilize spatial structures. Steel cables belong to the metal rigging category of hardware rigging. They are made of multiple strands of metal wire twisted together. The length needs to be adjusted according to actual usage requirements. Steel cables are cut into sections using appropriate cutting devices, and clamps are required to hold them during cutting.

[0003] An automatic clamp for rigging cutting, application number CN201922380773.8, describes a base box with a carrier plate fixedly connected to the left side of its back. A reduction motor is fixedly connected to the top of the carrier plate, and a disc is fixedly connected to the output end of the reduction motor inside the base box. A connecting plate is movably connected to the bottom of the disc's front side. A bearing is movably connected to the back of the base box's inner wall via a rotating shaft, and a rotating plate is fixedly connected to the left side of the bearing. This patent solves the problem of existing rigging cutting clamps lacking automatic clamping function by using a base box, carrier plate, reduction motor, disc, connecting plate, bearing, rotating plate, transmission plate, transmission rod, slide rod, slip ring, lifting frame, lifting plate, vertical rod, pressure plate, fixed platform, and cutting device body in a coordinated manner. This automatic clamp for rigging cutting has the advantage of automatic clamping, saving users a significant amount of time and improving the efficiency of rigging processing. However, it only clamps one end of the rigging, which makes the cutting section unstable during cutting, thus affecting the accuracy of the cut and potentially damaging the cutting edge. Furthermore, the use of plate-shaped clamps for clamping makes the clamping unstable. Summary of the Invention

Each of the multiple fixed cylinders has a rotating rod rotatably passing through it. Each of the multiple rotating rods is fixedly connected to the multiple one-way screws.

[0008] Furthermore, a protective component is installed on the base. The protective component includes a mounting groove on the base, in which a protective plate is placed. A movable cavity is formed on the base, and a second spring is fixedly connected to the inner wall of the movable cavity.

The actuating rod is fixedly connected to the second locking block. A second locking groove is formed on the side wall of the protective plate, and the second locking block and the second locking groove are matched.

[0009] Furthermore, the fixing assembly includes a working cavity on the base, a bidirectional screw is rotatably connected to the inner wall of the working cavity, two movable plates are slidably connected inside the working cavity, the bidirectional screw is threaded through the two movable plates, a clamping block is fixedly connected to each of the two movable plates, the two clamping blocks slidably pass through the base, two fixing grooves are opened on the side wall of the base, the two clamping blocks are respectively matched with the two fixing grooves, and a connecting rod is rotatably passed through the base, the connecting rod is fixedly connected to the bidirectional screw.

[0010] Furthermore, a plurality of connecting blocks are fixedly connected to the side wall of the base, and a fixing bolt slides through each of the plurality of connecting blocks.

This allows the device to stably clamp rigging of different sizes, thus improving the practicality of the device.

[0014] 2. During processing, the motor starts working, causing the clamping ring to rotate. This rotation of the clamped rigging allows for adjustment of the contact position between the rigging and the cutting tool, thus adjusting the direction of force at the cutting point and distributing the cutting force over a wider area. This prevents damage to the rigging or cutting tool due to single-point overload.

Detailed Implementation

[0019] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figures 1-8 As shown, this embodiment of the invention proposes a cutting fixture for hardware rigging, comprising: Base 1 has two placement slots 2. Two fixing components are installed on base 1. A base 3 is placed in each of the two placement slots 2. A fixing ring 4 is fixedly connected to each of the two bases 3. A rotating ring 5 is rotatably connected to each of the two fixing rings 4. A clamping ring 6 is installed on each of the two rotating rings 5. Multiple limiting slots 7 are formed on each of the two rotating rings 5. Multiple limiting blocks 8 are fixedly connected to each of the two clamping rings 6. Each limiting slot 7 corresponds one-to-one with each limiting block 8. Limiting components are installed on each of the two rotating rings 5. The limiting components include those formed on the rotating rings 5. The moving groove 9 is fixedly connected to the inner wall of the moving groove 9. A first spring 10 is fixedly connected to the first spring 10. A first locking block 11 is fixedly connected to the first spring 10. The first locking block 11 is slidably connected in the moving groove 9. The locking end of the first locking block 11 slides through the rotating ring 5. A first locking groove is opened on one of the limiting blocks 8. The first locking block 11 and the first locking groove match. A toggle rod is slidably connected in the moving groove 9. The toggle rod is fixedly connected to the first locking block 11. Limiting bolts 12 slide through multiple limiting blocks 8. Multiple limiting bolts 12 are threadedly connected to the rotating ring 5. According to the size of the rigging, select a clamping ring 6 with a suitable inner diameter, align the limiting block 8 on the clamping ring 6 with the limiting groove 7, and then insert the limiting block 8. The limiting block 8 will contact the first locking block 11, and the first locking block 11 will be subjected to force, causing the first spring 10 to contract. When the first locking block 11 is aligned with the first locking groove, the first spring 10 will return to its original position, and the first locking block 11 will move into the first locking groove, thus fixing the limiting block 8. This temporarily limits the clamping ring 6 to the rotating ring 5. Then, the user uses the limiting bolt 12 to fix the clamping ring 6 and the rotating ring 5. By setting two clamping rings 6, the two ends of the rigging are clamped, achieving stable clamping of the rigging. Furthermore, the detachable clamping ring 6 allows the user to easily replace clamping rings 6 with different inner diameter sizes, thereby enabling the device to stably clamp rigging of different sizes and improving the practicality of the device.

[0021] like Figure 3 As shown, a rotating assembly is installed on one of the bases 3. The rotating assembly includes a motor 13 fixedly installed on the base 3, a rotating gear 14 rotatably connected to the base 3, the rotating end of the motor 13 fixedly connected to the rotating gear 14, a toothed ring 15 fixedly connected to the side wall of the rotating ring 5, the rotating gear 14 and the toothed ring 15 meshing with each other, a protective cover fixedly connected to the fixed ring 4, a rotating opening on the protective cover, the rotating gear 14 located in the rotating opening, and clamping assemblies installed on both clamping rings 6. The disc cutter cutting device 30 processes the rigging. During cutting, the motor 13 starts working, and under the transmission of the rotating gear 14 and the gear ring 15, the clamping ring 6 rotates. The rotation of the clamped rigging can be adjusted. By rotating, the contact position between the rigging and the cutting tool of the disc cutter cutting device 30 can be adjusted, and the force direction at the cutting point can be adjusted so that the cutting force is distributed to a wider area, avoiding single-point overload and damage to the rigging or the cutting tool.

[0022] like Figure 4 As shown, the clamping assembly includes multiple fixed cylinders 16 that are fixedly connected to both sides of the clamping ring 6. Each fixed cylinder 16 has a sliding rod 17 slidably connected inside it. Each fixed cylinder 16 has a one-way screw 18 rotatably connected to its inner wall. Each one-way screw 18 is threadedly connected to the sliding rod 17. Each sliding rod 17 has an arc-shaped clamping plate 19 fixedly connected to it. Each fixed cylinder 16 has a rotating rod that rotatably passes through it. Each rotating rod is fixedly connected to the one-way screw 18. The user passes the rigging through the clamping ring 6, and then turns the knob 32 to rotate the one-way screw 18, so that the arc-shaped clamping plate 19 can clamp and fix the rigging.

[0023] like Figure 1 and Figure 5 As shown, a protective assembly is installed on the base 1. The protective assembly includes a mounting groove 20 on the base 1, a protective plate 21 placed in the mounting groove 20, and an observation window fixedly connected to the protective plate 21. The observation window allows the user to observe the rigging cutting situation. A protective shell 33 is fixedly connected to the side wall of the base 3. The protective shell 33 matches the motor 13 and can protect the motor 13 from damage caused by external interference. A moving cavity is opened on the base 1. A second spring 22 is fixedly connected to the inner wall of the moving cavity. A second locking block 23 is slidably connected in the moving cavity. The second spring 22 is fixedly connected to the second locking block 23. The second locking block 23 slides through the base 1. A toggle groove is opened in the inner wall of the moving cavity. A toggle rod is slidably connected in the toggle groove. The toggle rod is fixedly connected to the second locking block 23. A second locking groove is opened on the side wall of the protective plate 21. The user inserts the protective plate 21 into the mounting slot 20, and the second locking block 23 cooperates with the second locking slot to fix the protective plate 21. By using the detachable protective plate 21, the protective plate 21 can block the sparks and flying chips generated during cutting, thereby improving the safety of cutting and processing.

[0024] like Figure 1 and Figure 5As shown, the first locking block 11 and the second locking block 23 are both wedge-shaped. The second locking block 23 matches the second locking slot. The fixing assembly includes a working cavity 24 on the base 1. A bidirectional screw 25 is rotatably connected to the inner wall of the working cavity 24. Two movable plates 26 are slidably connected inside the working cavity 24. The bidirectional screw 25 is threaded through the two movable plates 26. A clamping block 27 is fixedly connected to each of the two movable plates 26. The two clamping blocks 27 are slidably connected through the base 1. Two fixing slots are opened on the side wall of the base 3. The two clamping blocks 27 are respectively matched with the two fixing slots. A connecting rod is rotatably connected through the base 1. The connecting rod is fixedly connected to the bidirectional screw 25. A handle 31 is fixedly connected to the connecting rod. The handle 31 facilitates the user to rotate the connecting rod. A knob 32 is fixedly connected to the rotating rod. The knob 32 facilitates the user to rotate the rotating rod, improving the portability of the device. The base 1 is fixed to the processing table using the fixing bolt 29. Then, the user places the base 3 in the placement slot 2, rotates the handle 31, and the bidirectional screw 25 rotates, so that the two moving plates 26 slide in the working cavity 24. The two clamping blocks 27 can clamp and fix the base 3, thus completing the fixation of the base 3. By setting the detachable base 3, it is convenient for the user to move the device, which improves the portability of the device.

[0025] like Figure 1 As shown, multiple connecting blocks 28 are fixedly connected to the side wall of the base 1, and fixing bolts 29 slide through each of the multiple connecting blocks 28. A processing table is installed on the base 1, and the multiple fixing bolts 29 are threaded onto the processing table. A disc cutter cutting device 30 is installed on the processing table. The disc cutter cutting device 30 is existing technology. The disc cutter cutting device 30 mainly consists of a high-speed rotating disc-shaped blade, a drive device, a transmission shaft, a clamping mechanism, and a control device. Its cutting principle is based on the high-speed rotation of the blade driven by the drive device. Cutting is achieved by the shearing force or cutting force generated when the sharp cutting edge contacts the material. It will not be described in detail here.

[0026] The detailed working process of this invention is as follows: The base 1 is fixed to the processing table using fixing bolts 29. Then, the user places the base 3 in the placement slot 2, rotates the handle 31, and the double-ended screw 25 rotates, causing the two moving plates 26 to slide within the working cavity 24. The two clamping blocks 27 then clamp and fix the base 3, completing the fixation of the base 3. The detachable base 3 facilitates user handling of the device, improving its portability. Next, according to the size of the rigging, a clamping ring 6 with a suitable inner diameter is selected, and the limiting block 8 on the clamping ring 6 is aligned with the limiting groove 7. When the limiting block 8 is inserted, it contacts the first locking block 11. The first locking block 11 is then subjected to force, causing the first spring 10 to contract. When the first locking block 11 is aligned with the first slot, the first spring 10 returns to its original position, and the first locking block 11 moves into the first slot, thus fixing the limiting block 8. This temporarily limits the clamping ring 6 to the rotating ring 5. The user then uses the limiting bolt 12 to secure the clamping ring 6 and the rotating ring 5. By setting two clamping rings 6, both ends of the rigging are clamped, achieving stable clamping of the rigging. Furthermore, a detachable clamping ring 6 is provided, allowing users to easily replace clamping rings 6 with different inner diameters. This enables the device to stably clamp rigging of different sizes, improving its practicality. The user then passes the rigging through the clamping ring 6 and rotates the knob 32, causing the one-way screw 18 to rotate. The arc-shaped clamping plate 19 then clamps and fixes the rigging. The user then inserts the protective plate 21 into the mounting slot 20. The second locking block 23 engages with the second locking slot to fix the protective plate 21. The detachable protective plate 21 provides protection. Plate 21 can block sparks and flying chips generated during cutting, thereby improving the safety of cutting. Subsequently, the disc cutter cutting device 30 processes the rigging. During cutting, motor 13 starts to work. Under the transmission of rotating gear 14 and gear ring 15, clamping ring 6 rotates, which can adjust the rotation of the clamped rigging. By rotating, the contact position between the rigging and the cutting tool of the disc cutter cutting device 30 can be adjusted, and the force direction at the cutting point can be adjusted, so that the cutting force is distributed to a wider area, avoiding single-point overload and damage to the rigging or cutting tool.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
