Description

Technical Field

[0001] This utility model relates to the field of cable processing equipment technology, and in particular to a pneumatic fixing clamp for thin cables. Background Technology

[0002] Currently, cable clamps are widely used in the processing or testing of cables. Traditional devices are usually equipped with cable clamping parts to clamp the cable, thereby fixing the cable and preventing it from falling off and affecting the operation of the corresponding device.

[0003] Related technology can be found in Chinese Patent No. CN222563440U, which discloses a cable clamp for power wiring. The clamp includes a housing with cable grooves at both the top and bottom. Outer baffles are integrally formed on the inner sides of both the top and bottom of the housing. A pull rod is slidably mounted on the outer baffle, and a clamping plate is fixedly mounted on the inner end of the pull rod. An inner baffle is fixedly mounted on the pull rod, and a spring is provided between the outer and inner baffles. Two pull rods on the same side are fixedly connected to uprights at their outer ends, and hand rings are fixedly mounted on the uprights. This application provides a cable clamp for power wiring. By pulling the hand ring, the clamping plate moves outward, inserting the cable into the cable groove. The spring's deformation characteristic allows the clamping plate to move inward. The clamping plate and the cable groove work together to clamp the cable, enabling the clamping of cables of different diameters within the cable groove.

[0004] Regarding the aforementioned technologies, when the device clamps the cable, the two side baffles are smooth surfaces, resulting in low friction between the baffles and the cable. This makes it easy for the device to loosen the clamping of the cable, which can lead to the cable detaching from the device and affect the clamping effect. Utility Model Content

[0005] To improve the gripping effect of the device on thin cables, this application provides a pneumatic clamp for thin cables.

[0006] This application provides a pneumatic fixing clamp for thin cables, which adopts the following technical solution:

[0007] A pneumatic clamp for fixing thin cables includes two opposing clamping blocks, with a support portion between the clamping blocks. The support portion has a groove along its own length. Each clamping block has a movable block at its lower end. The movable block is inserted into the groove and moves along the length of the groove. The support portion is provided with a driving component for driving the movable block to move along the groove. Each clamping block has a fixed block on its side that is close to each other, and the surface of the fixed block is covered with a PU pad.

[0008] By adopting the above technical solution, the support part supports the clamping block while the driving component drives the moving block to move along the slide groove. When the moving block moves, it drives the clamping block to move, thereby causing the clamping block to move the two fixed blocks closer or further apart, so as to clamp or release the cable. The PU pad is made of soft material, which covers the entire cable when clamping it, increasing the contact area between the clamp and the cable, which helps to reduce the probability of cable breakage and detachment, and improves the clamping effect of the clamp.

[0009] Optionally, each clamping block includes an upper assembly and a middle assembly, and the upper assembly and the middle assembly are detachably connected by bolts. The fixing block is connected to the upper assembly, and the middle assembly and the moving block are detachably connected by bolts.

[0010] By adopting the above technical solution, operators can disassemble and assemble the clamping block by removing the bolts, which facilitates the combination of upper and lower assemblies of different sizes with the moving block to meet different work needs and improve the convenience of the device's operation.

[0011] Optionally, the upper assembly blocks extend in a direction that brings them closer together along the length of the slide groove, and when the two upper assemblies approach each other, a gap is left between the two middle assemblies for cables to pass through.

[0012] By adopting the above technical solution, after the processing is completed, the two clamping blocks separate, and the cable can be moved down into the gap between the two intermediate assemblies, which helps to improve the efficiency of cable disassembly.

[0013] Optionally, a trapezoidal block is fixed on the side of the fixing block near the corresponding upper assembly. The upper assembly has an assembly groove adapted to the trapezoidal block on the side near the trapezoidal block. The trapezoidal block is inserted into the assembly groove and fits against the inner wall of the assembly groove. The upper assembly is provided with a positioning element for fixing the trapezoidal block.

[0014] By adopting the above technical solution, the trapezoidal block is inserted into the assembly groove and slides along the length of the assembly groove. The assembly groove guides and limits the trapezoidal block, and the positioning component positions the fixed block by positioning the trapezoidal block, which helps to improve the stability of the device operation.

[0015] Optionally, the positioning element includes an elastic element and a positioning block. The upper assembly body has a fixing groove that communicates with the assembly groove. The fixing groove is set perpendicular to the trapezoidal block in the horizontal direction. The positioning block is located in the fixing groove and moves closer to or away from the trapezoidal block along the length of the fixing groove. The elastic element is placed in the fixing groove. In its natural state, the elastic element pushes the positioning block closer to the trapezoidal block. The trapezoidal block has a positioning hole that matches the positioning block on the side away from the PU pad. When the positioning block is inserted into the positioning hole, it fits against the inner wall of the positioning hole.

[0016] By adopting the above technical solution, the fixing groove supports and limits the elastic element. The elastic element pushes the positioning block along the fixing groove toward the trapezoidal block and inserts it into the positioning hole to fix and limit the trapezoidal block, thereby fixing and limiting the fixing block and PU pad, which helps to improve the stability of the device operation.

[0017] Optionally, the positioning block is spherical, and a limiting plate is provided on the side of the upper assembly near the fixing block. The limiting plate has a circular hole that is directly opposite to the fixing groove. The diameter of the circular hole is not greater than the maximum diameter of the positioning block. In the natural state of the elastic element, one side of the positioning hole passes through the circular hole and protrudes outward.

[0018] By adopting the above technical solution, the limiting plate limits the lateral displacement of the steel ball, reducing the probability of the fixing block falling out of the fixing groove.

[0019] Optionally, a plurality of screws are provided between the limiting plate and the upper assembly, and the screws pass through the limiting plate and are threadedly connected to the limiting plate.

[0020] By adopting the above technical solution, the limiting plate is connected to the upper assembly by screws, which helps to improve the stability and reliability of the device structure.

[0021] Optionally, the upper surfaces on both sides of the support portion along the width direction are inclined surfaces.

[0022] By adopting the above technical solution, the inclined plane reduces the probability of damage caused by the cable coming into contact with the support, which helps to improve the safety of the device operation.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. While the support unit supports the clamping block, the driving component drives the moving block to move along the slide groove. When the moving block moves, it drives the clamping block to move, which in turn causes the clamping block to move the two fixed blocks closer or further apart, so as to clamp or release the cable. The PU pad is made of soft material, which covers the entire cable when clamping it, increasing the contact area between the clamp and the cable, which helps to reduce the probability of cable breakage and detachment, and improves the clamping effect of the clamp.

[0025] 2. Operators can disassemble and assemble the clamping blocks by removing the bolts, which makes it easy to combine upper and lower assemblies of different sizes with the moving blocks to meet different work needs and improve the convenience of the device's operation.

[0026] 3. After the processing is completed, the two clamping blocks separate, and the cable can be moved down into the gap between the two intermediate assemblies, which helps to improve the efficiency of cable disassembly. Attached Figure Description

[0031] The present application will be further described in detail below with reference to all the accompanying drawings.

[0032] This application discloses a pneumatic clamp for fixing thin cables. Example

[0033] Reference Figure 1 A pneumatic clamp for securing thin cables includes a support portion 1 and two clamping blocks 2. A groove 12 is formed on the upper surface of the support portion 1 along its length. A drive component 11 is installed inside the support portion 1. The drive component 11 can be a gripper cylinder, with its two output ends located within and at opposite ends of the groove 12. When the gripper cylinder operates, it drives the two output ends to move closer or further apart along the groove 12. The gripper cylinder is existing technology and will not be described in detail here.

[0034] Reference Figure 1 The clamping block 2 includes an upper assembly 23 and a middle assembly 24. The upper assembly 23 is located above the middle assembly 24. The upper assembly 23 and the middle assembly 24 are detachably connected by bolts. Movable blocks 25 are detachably connected to the lower end of the middle assembly 24. The movable blocks 25 are all located within the slide groove 12 and are respectively connected to the two output ends of the gripper cylinder. The gripper cylinder drives the movable blocks 25 to slide laterally through the output ends. When the movable blocks 25 move, they cause the two clamping blocks 2 to move closer or further apart. The cable passes between the two clamping blocks 2, and the two clamping blocks 2 cooperate to clamp or remove the cable. Operators can replace different upper assemblies 23 and middle assemblies 24 to adapt to different work requirements, which improves the ease of operation of the device.

[0035] Reference Figure 1The two upper assemblies 23 extend from bottom to top in a direction that approaches each other. When the two upper assemblies 23 approach each other, there is a gap between the two middle assemblies 24. When the two upper assemblies 23 move away from each other, the cable can be moved down between the two middle assemblies 24 so that the cable passes through the gap between the two middle assemblies 24, which facilitates cable disassembly and helps to improve the efficiency of cable disassembly.

[0036] Reference Figure 1 and Figure 2 Each of the upper assemblies 23 has a fixing block 21 installed on one side where they are close to each other. The outer surface of each fixing block 21 is covered with a PU pad 211. The cable passes between the two PU pads 211. When the two upper assemblies 23 approach each other, they cause the two fixing blocks 21 to approach each other and clamp the cable through the PU pads 211. The PU pads 211 increase the contact area between the fixing blocks 21 and the cable, allowing the fixing blocks 21 to better clamp the cable. Furthermore, the control structure of the gripper cylinder is located at the bottom, allowing the operator to control the gripper cylinder by stepping on it. This ensures that the fixing blocks 21 continuously clamp the cable, reducing the probability of the cable falling off or breaking, and improving the clamping effect of the device on the cable.

[0037] Reference Figure 1 and Figure 2 A trapezoidal block 22 is fixed on the side of the fixing block 21 near the upper assembly 23. An assembly groove 231 is opened on the side of the upper assembly 23 near the trapezoidal block 22 along the width direction of the upper assembly 23. The cross-section of the assembly groove 231 is trapezoidal and matches the size of the trapezoidal block 22. The trapezoidal block 22 is inserted into the assembly groove 231 and slides along the length direction of the assembly groove 231. The assembly groove 231 guides and limits the fixing block 21 through the trapezoidal block 22, which helps to improve the convenience of installing and disassembling the fixing block 21.

[0038] Reference Figure 1 and Figure 2The upper assembly 23 has a horizontally extending fixing groove 233 on the side near the trapezoidal block 22, and the fixing groove 233 is perpendicular to the end face of the trapezoidal block 22. A positioning element 234 for fixing the trapezoidal block 22 is fixedly installed on the side of the upper assembly 23 near the fixing block 21. The positioning element 234 includes an elastic element 2341 and a positioning block 2342. The elastic element 2341 can be a spring. Both the spring and the positioning block 2342 are located within the fixing groove 233. The positioning block 2342 is located on the side of the spring away from the upper assembly 23 and is in contact with the spring. The positioning block 2342 is spherical. In the initial state, the spring pushes the positioning block 2342 away from the fixing groove 233. The trapezoidal block 22 has a positioning hole 221 that matches the positioning block 2342 on the side near the upper assembly 23. In the working state, one end of the positioning block 2342 is located in the positioning hole 221 and the other end is located in the fixing groove 233 to fix the trapezoidal block 22, thereby fixing and limiting the fixing block 21, which helps to improve the stability of the device.

[0039] Reference Figure 2 and Figure 3 A limiting plate 232 is installed on the side of the upper assembly 23 near the trapezoidal block 22. The limiting plate 232 has screws that pass through it and the upper assembly 23 and are threadedly connected to it, thus fixing the limiting plate 232. The limiting plate 232 has a transversely lateral opening 2321 that matches the positioning block 2342. The circular hole 2321 is directly opposite the positioning hole 221 and the fixing groove 233. Under the pushing action of a spring, the positioning block 2342 passes through the circular hole 2321 and is inserted into the positioning hole 221. The diameter of the circular hole 2321 is smaller than the maximum diameter of the positioning block 2342, which helps reduce the probability of the fixing block 21 falling out of the fixing groove 233 and improves the stability of the device structure.

[0040] Reference Figure 1 The upper surfaces of both sides of the support part 1 along the width direction are inclined surfaces, and the direction of inclination of the inclined surfaces is the direction of cable disassembly. This reduces the probability of damage caused by the cable contacting the sides of the support part 1 during installation and removal, and helps to improve the safety of the device operation.

[0041] The implementation principle of the pneumatic fixing clamp for thin cables in this application embodiment is as follows: the gripper cylinder drives the moving block 25 to move along the length direction of the slide groove 12 through the output end, thereby causing the two clamping blocks 2 to move closer or further away from each other. The cable passes through the middle of the two fixing blocks 21. The PU pad 211 increases the contact area between the fixing block 21 and the cable, reduces the probability of the cable falling off or breaking, improves the clamping effect of the clamp, and helps to improve the stability of the device operation.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
