Description

Technical Field

[0001] This utility model relates to the field of cable processing technology, specifically to a twisting machine with an adjustable clamp position. Background Technology

[0002] Whether it's connecting wires inside electronic devices or bundling and securing cables in large electrical equipment, twisting machines are key equipment for ensuring the standardized and stable installation of cables.

[0003] However, traditional twisting machines have fixed clamp positions and twisting interface positions during design and use, making it impossible to flexibly change the angle between the clamp and the twisting interface. This angle has a crucial impact on the twisting effect, directly determining the tightness of the twist.

[0004] In actual production, the ideal twisting tightness and density vary depending on the material and diameter of the cable. However, traditional twisting machines lack the ability to adjust the angle between the clamp and the twisting interface. To achieve the desired twisting effect, the only solution is often to increase the rotation speed. However, this approach has significant drawbacks. On the one hand, increasing the rotation speed increases the complexity of operation and makes it extremely inconvenient to use. On the other hand, excessively high rotation speeds subject the cable to greater torsional forces, greatly increasing the risk of cable breakage. If the cable breaks during the twisting process, it not only leads to material waste and increased production costs but also affects production progress and reduces production efficiency. Therefore, a twisting machine with adjustable clamp position is proposed. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a twisting machine with an adjustable clamp position. It has the advantages of flexibly adjusting the clamp position to change the angle between the clamp and the twisting interface and controlling the tightness of the twist. It solves the problems of traditional twisting machines where the clamp position is fixed and the angle between the clamp and the twisting interface cannot be changed. The twisting effect can only be adjusted by increasing the speed, which leads to complicated operation, easy cable breakage, increased cost, and reduced production efficiency.

[0007] (II) Technical Solution

[0008] To achieve the aforementioned goal of flexibly adjusting the position of the clamp, thereby changing the angle between the clamp and the twisting interface and controlling the tightness of the twist, this utility model provides the following technical solution:

[0009] An adjustable clamp position twisting machine includes a base, on the upper end of which the twisting machine body and a fixed bracket are fixedly installed. A screw is rotatably arranged on the side of the fixed bracket away from the twisting machine, and the other end of the screw is fixedly connected to a motor that is fixed to the base by a pad.

[0010] The twisting axis of the twisting machine is the same as the axis of the screw and the motor.

[0011] The screw is provided with a movable component, which includes a sleeve, a mounting block, a connecting rod, and a cable reel;

[0012] A clamp assembly is fixedly installed on the connecting rod. The clamp assembly includes a guide box, a slider, a roller, and a screw.

[0013] The first screw has a one-way thread, and the second screw has a two-way thread.

[0014] The preferred technical solution of this utility model is that the sleeve is threadedly connected to the screw, and a plurality of mounting blocks are provided and are circularly distributed about the thread axis. The two ends of the connecting rod on the side closer to the twisting machine body are respectively hinged to the mounting block and the fixed bracket, and the two ends of the connecting rod on the side away from the twisting machine body are respectively hinged to the mounting block and the sleeve.

[0015] A preferred embodiment of this invention is that each mounting block is rotatably connected to a cable reel, and all the connecting rods are of the same size.

[0016] The preferred technical solution of this utility model is that the clamp assembly is installed on the connecting rod near the body of the twisting machine, and at least two sets of clamp assemblies are installed on each connecting rod.

[0017] A preferred embodiment of this invention is that the hinge rotation planes of the connecting rod, the sleeve, the mounting block, and the fixed bracket all intersect with the axis of the screw.

[0018] The preferred technical solution of this utility model is that the guide box and the connecting rod are fixedly installed, and two sliders are slidably arranged in each guide box, and a roller is rotatably connected to the upper end of each slider.

[0019] The preferred technical solution of this utility model is that the second screw is rotatably connected to the guide box and threadedly connected to the first slider and the second slider, and the threaded connections of the first slider and the second slider are in opposite directions.

[0020] (III) Beneficial Effects

[0021] Compared with the prior art, this utility model provides a twisting machine with an adjustable clamp position, which has the following advantages:

[0022] This adjustable clamp position twisting machine uses a motor to drive a screw to rotate, which in turn moves a sleeve along the screw. This causes the connecting rod to rotate at the hinge point of the fixed bracket, changing the cable angle between the clamp assembly and the twisting machine body. This allows for control over the tightness of the twist, avoiding the drawback of traditional twisting machines that can only adjust the twisting effect by increasing the speed. It also reduces the risk of cable breakage and improves production efficiency and product quality.

[0023] This adjustable clamp twisting machine uses two sliders, one with opposite threaded connections, inside a guide box. Rotating screw two allows the two sliders to slide in opposite directions within the guide box, clamping the cable in conjunction with rollers. This not only allows for adjustment of the clamping force according to different cables but also ensures clamping stability. Furthermore, multiple clamping assemblies can operate on multiple cables simultaneously, greatly improving the equipment's flexibility and processing efficiency. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] Please see Figure 1-4 A twisting machine with an adjustable clamp position includes a base 1, on which a twisting machine body 2 and a fixed bracket 4 are fixedly mounted. A screw 5 is rotatably mounted on the side of the fixed bracket 4 away from the twisting machine, and the other end of the screw 5 is fixedly connected to a motor 3 fixed to the base 1 via a pad 31. The twisting axis of the twisting machine is coaxial with the axis of the screw 5 and the axis of the motor 3.

[0033] A movable component 6 is provided on screw 5, which includes a sleeve 61, a mounting block 62, a connecting rod 63, and a cable reel 64. A chuck assembly 7 is fixedly mounted on the connecting rod 63, which includes a guide box 71, a slider 72, a roller 73, and screw 74. Screw 5 has a unidirectional thread, while screw 74 has a bidirectional thread.

[0034] It should be noted that the unidirectional thread design of screw 5 allows the sleeve 61 to move linearly in one direction when screw 5 rotates, thereby driving the movable component 6 to move and adjust the position of the chuck. The bidirectional thread design of screw 74, on the other hand, is designed to allow sliders 721 and 722 to slide in opposite directions within the guide box 71, thus adjusting the clamping force. These different thread designs are carefully designed according to the functional requirements of each part of the equipment, fully leveraging the equipment's performance advantages.

[0035] It should be further explained that the cable of the device is wound and stored on the cable reel 64, and then passes through the clamp assembly 7 in sequence, finally connecting to the twisting machine body 2 for twisting. Both the twisting machine and the motor 3 are powered by an external power source.

[0036] In this embodiment, the sleeve 61 is threadedly connected to the screw 5, and the mounting blocks 62 are provided in a plurality of circularly distributed about the axis of the screw 5. The two ends of the connecting rod 63 on the side closer to the twisting machine body 2 are respectively hinged to the mounting block 62 and the fixed bracket 4, and the two ends of the connecting rod 63 on the side farther away from the twisting machine body 2 are respectively hinged to the mounting block 62 and the sleeve 61.

[0037] It should be noted that this hinged design allows the sleeve 61 to move linearly along the screw 5 when the screw 5 rotates under the drive of the motor 3. Due to the hinged effect of the connecting rod 63, the mounting block 62 and the entire movable assembly 6 will move, thereby enabling flexible adjustment of the position of the clamp assembly 7 and changing the angle between the clamp and the twisted cable interface to adapt to the twisting requirements of different cables.

[0038] In this embodiment, each mounting block 62 is rotatably connected to a cable reel 64, and all connecting rods 63 are the same size.

[0039] It should be noted that the cable reel 64 is used to store cables and moves together with the connecting rod 63. This prevents the cable between the clamp assembly 7 and the cable reel 64 from being torn off during the rotation of the connecting rod 63.

[0040] It should be further explained that the connecting rods 63 of the same size ensure the consistency and stability of the moving components 6 during the movement, reducing problems such as movement incoordination and inaccurate adjustment of the clamp position that may be caused by size differences.

[0041] In this embodiment, the clamp assembly 7 is installed on the connecting rod 63 near the twisting machine body 2, and at least two sets of clamp assemblies 7 are installed on each connecting rod 63.

[0042] It should be noted that this design allows the equipment to clamp and twist multiple cables simultaneously, greatly improving production efficiency and meeting the needs of large-scale production.

[0043] In this embodiment, the hinge rotation planes of the connecting rod 63, the sleeve 61, the mounting block 62, and the fixed bracket 4 all intersect with the axis of the screw 5.

[0044] It should be noted that this design is intended to ensure that when the screw 5 rotates and drives the sleeve 61 to move, the connecting rod 63 can rotate stably around the hinge point, thereby accurately changing the position and angle of the chuck assembly 7. If the hinge rotation plane does not intersect with the axis of the screw 5, it may cause the connecting rod 63 to deviate or wobble during movement, affecting the adjustment accuracy of the chuck position and the twisting effect.

[0045] In this embodiment, the guide box 71 and the connecting rod 63 are fixedly installed. Two sliders 72 are slidably arranged in each guide box 71, and each slider 72 is rotatably connected to a roller 73 at its upper end.

[0046] It should be noted that the guide box 71 provides a stable motion track for the slider 72, ensuring that the slider 72 can slide along a straight line.

[0047] It should be further explained that the roller 73 rotatably connected to the upper end of the slider 72 is used to clamp the cable. The rotation of the roller 73 can reduce the friction of the cable during the clamping process, avoid damage to the cable surface, and straighten the cable to facilitate subsequent twisting operations.

[0048] In this embodiment, screw 74 is rotatably connected to guide box 71 and threadedly connected to slider 721 and slider 722. The threaded connections of slider 721 and slider 722 are in opposite directions.

[0049] It should be noted that when the screw 74 is rotated, the two sliders 72 will slide in opposite directions in the guide box 71 due to the opposite direction of the threaded connection, thereby adjusting the clamping force of the cable and meeting the clamping requirements of different cables.

[0050] In summary, this adjustable clamp position twisting machine, driven by motor 3, rotates screw 5, causing sleeve 61 to move along screw 5, which in turn causes connecting rod 63 to rotate at the hinge point of fixed bracket 4. This changes the cable angle between clamp assembly 7 and twisting machine body 2, thereby controlling the tightness of the twist. This avoids the drawback of traditional twisting machines that can only adjust the twisting effect by increasing the speed, reduces the risk of cable breakage, and improves production efficiency and product quality.

[0051] This adjustable clamp twisting machine uses two sliders 721 with opposite threaded connections, 721 and 7222, located within a guide box 71. Rotating the screw 74 causes the two sliders 722 to slide in opposite directions within the guide box 71, working in conjunction with rollers 73 to clamp the cable. This not only allows for adjustment of the clamping force according to different cables but also ensures clamping stability. Furthermore, multiple clamp assemblies 70 can operate on multiple cables simultaneously, greatly improving the equipment's flexibility and processing efficiency.

[0052] Working principle: The cable is wound onto the cable reel 64, and then passes through the clamp assembly 7 before connecting to the twisting machine body 2. The motor 3 is started, driving the screw 5 to rotate. Since the sleeve 61 is threaded to the screw 5, it moves linearly along the screw 5 under the action of the unidirectional thread. Because the connecting rod 63 is hinged at both ends to the mounting block 62, the fixed bracket 4, and the sleeve 61 respectively, when the sleeve 61 moves, the hinge action of the connecting rod 63 drives the mounting block 62 and the entire movable assembly 6 to move, thereby changing the position and angle of the clamp assembly 7. This adjusts the angle between the clamp and the twisting interface to adapt to the twisting requirements of different cables.

[0053] When adjusting the cable clamping force, rotate screw 74. Because screw 74 has a bidirectional thread and is threadedly connected to sliders 721 and 722, with the threads of the two sliders 72 connected in opposite directions, the two sliders 72 will slide in opposite directions within the guide box 71, thereby changing the clamping force on the cable. The rotation of roller 73 reduces cable clamping friction, preventing cable damage and straightening the cable. The equipment can clamp and twist multiple cables simultaneously, meeting the needs of large-scale production and improving production efficiency and product quality.

[0054] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
