Description

Technical Field

[0001] This invention relates to the field of machining equipment technology, specifically to a five-axis swing head and its anti-tangle mechanism. Background Technology

[0002] The five-axis swivel head is one of the core components of high-end CNC machine tools. By enabling the tool itself to have the ability to "swivel" and "rotate", it achieves efficient, high-precision, one-time machining of complex spatial curved surface parts, and is a representative of advanced manufacturing capabilities.

[0003] Patent publication number CN116038359B discloses a servo AC bidirectional five-axis oscillating head, including a ram end seat, an oscillating head support assembly, and an electric spindle. A C-axis assembly is rotatably mounted in the central hole of the ram end seat. A pair of C-axis drive motors are disposed at the upper end of the ram end seat, each C-axis drive motor simultaneously driving the C-axis assembly to rotate via a corresponding C-axis gear transmission mechanism. The upper end of the oscillating head support assembly is fixedly connected to the lower end of the C-axis assembly. A pair of A-axis drive motors are installed inside the oscillating head support assembly, and an electric spindle support is rotatably mounted at the lower end of the oscillating head support assembly. An electric spindle for mounting milling tools is fixedly mounted in the electric spindle support. Each A-axis drive motor simultaneously drives the electric spindle support to rotate via a corresponding A-axis gear transmission mechanism. This invention has a reasonable structural design, ensuring the accuracy of the swing angle drive while possessing a large driving torque, good dynamic performance, and relatively fast swing speed. The above solution uses a clamp-type brake to lock and position the swing angle of the electric spindle in the vertical plane.

[0004] Patent publication number CN119282784B discloses an electrically driven five-axis oscillating head, including an oscillating head assembly. The oscillating head assembly includes a housing 1, a housing 2 bolted to one outer wall of housing 1, and a housing 3 bolted to the other outer wall of housing 1. When adjusting the direction of the oscillating head, the invention can operate the second drive motor to start, causing the lead screw to move the piston plate, which then retracts to the side of the storage tank. Subsequently, due to the action of the support spring, the connecting cylinder slides inside the slide cylinder, causing the locking block inside the slide cylinder to engage with the fixed cylinder, connecting the fixed cylinder to the connecting end. When the first drive motor is operated to adjust the direction of the mounting box, the movement of the transmission shaft causes the connecting end to rotate through the connecting cylinder, rotating the mounting box around housing 1, thus rotating the rotating end. This achieves the purpose of oscillating head movement with a single drive element, reducing the size and cost of the oscillating head. The above solution also offers the advantage of rapid installation.

[0005] To ensure accurate positioning of the five-axis swing head and prevent inertia, appropriate braking components are configured. However, existing braking structures are generally friction-based, such as clamps or disc brakes, which are prone to frictional wear and inaccurate braking time or speed. This necessitates quick stops, requiring the rotating shaft to bear greater strength, increasing its size and consequently raising manufacturing and operating costs. Alternatively, to improve swing head efficiency and reduce overall size, the number of connecting wires cannot be reduced. The transmission wires are usually fixed using cable ties or cable organizers, but the wires are still in direct contact. Their smooth surfaces are prone to tangling when rotating with the shaft. Furthermore, during maintenance, these components need to be cut, making them inconvenient for repeated use. As a result, the wire positioning structure is too rudimentary and has poor fixing effect.

[0006] Therefore, a five-axis swing head and its anti-tangle mechanism are proposed to solve the problems mentioned above. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a five-axis swing head and its anti-tangle mechanism, which can solve problems such as the need for the rotating shaft to bear greater strength, resulting in a larger size, higher manufacturing and usage costs, the need to cut cable ties and other components, inconvenience for repeated use, and an overly rudimentary wire harness positioning structure with poor fixing effect.

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0038] Please see Figure 1 - Figure 4 A five-axis sway head in this embodiment includes a five-axis sway head body 1 and a braking mechanism 4 disposed on one side of the five-axis sway head body 1 for braking support.

[0039] The main body 1 of the five-axis swing head is equipped with a rotating shaft 2 for main shaft transmission. One end of the rotating shaft 2 is equipped with a brake connecting plate 3. The brake connecting plate 3 is equipped with a brake protrusion 301 on the end face near the brake mechanism 4. The brake mechanism 4 includes a brake support plate 401 and a brake protrusion 402 that are in contact with the brake connecting plate 3 for braking. An air brake chamber 404 is opened inside the brake support plate 401 near the brake connecting plate 3. The air brake chamber 404 is connected to the outside. Air brake chambers 404 are provided on both sides of the brake support plate 401. A push head 405 is tightly installed on the inner wall of the air brake chamber 404. A rotating frame 407 is provided below the push head 405.

[0040] The five-axis sway head body 1 is a transmission five-axis sway head mechanism. The corresponding driving method and setting method inside are well known to those skilled in the art. Therefore, they are not described in detail in this embodiment. The braking mechanism 4 in this application can be set on one or both sides according to the single-arm or double-arm five-axis sway head. The position of the braking mechanism 4 is not limited to a certain axis. It can be set on one side of different axes according to the driving method of different models of products. It can be set on one side of a certain axis or on one side of multiple axes. The specific position and quantity can be reasonably determined according to the different models of the five-axis sway head. The specific installation method only needs to satisfy the horizontal movement of the braking support plate 401 inside the braking mechanism 4 to a fixed position. This installation method is a conventional processing method in the mechanical field. Therefore, it is not limited here.

[0041] First, the pusher head 405 slides tightly inside the air brake chamber 404, achieving a connection similar to that of a piston and piston cylinder. Gas is filled into the area formed between the conical portion of the pusher head 405 and the air brake chamber 404, sealing the entire air brake chamber 404 to ensure no air leakage under normal conditions. Therefore, when the brake support plate 401 is pushed towards the brake connecting plate 3, the rotating brake connecting plate 3 causes the brake protrusion 301 to contact the side of the brake bracket 402, pushing the brake bracket 402 in the direction of rotation of the brake connecting plate 3. This causes the brake bracket 402 to push the pusher head 405 into the air brake chamber 404. At this time, supported by the gas inside the air brake chamber 404, the movement of the pusher head 405 is resisted, thus preventing movement. The area between the air brake chamber 404 and the conical surface of the pusher head 405 gradually decreases, keeping the total amount of gas inside the air brake chamber 404 constant while reducing the volume at this point, thus increasing the pressure. This increases the gas resistance on the pusher head 405, providing a gradually increasing resistance effect for the braking protrusion 301. This causes the braking protrusion 301, the braking connecting disc 3, and the deceleration of one side of the swing head to gradually slow down, effectively preventing the braking connecting disc 3 from suddenly decelerating to a stop during movement. This avoids situations where the bearing or support structure needs excessive strength, or where the connecting parts break during emergency stops. Compared to existing friction braking or the use of interlocking structures, this reduces material wear and the impact of emergency stops, enabling the swing head in the five-axis swing head body 1 to achieve gradual braking with simple equipment materials.

[0042] After the gyroscope head is brought to a stop, the brake support plate 401 is reset and moved without affecting the subsequent movement of the gyroscope head. The movement of the brake support plate 401 can be achieved by a linear drive source such as a telescopic motor or cylinder, and then it is fixed on one side of the five-axis gyroscope head body 1. Corresponding limiting grooves are set directly between the brake support plate 401 and the outer protective shell, so that the brake support plate 401 can only move back and forth in a single direction. It is similar to setting a protrusion on the outer periphery of the brake support plate 401 and a groove inside the protective shell, so that the protrusion slides in the groove, thereby limiting the brake support plate 401 and preventing it from rotating, thus improving its strength during braking. The specific structure of this part can be set according to different equipment types. Its one-way limiting structure is a conventional technical means, so it is not limited here.

[0043] By setting brake support plates 401 and air brake chambers 404 of the same specifications on both sides of the sliding groove 403, the swing head and rotating shaft 2 can be equally limited and supported in different rotation directions, achieving the effect of bidirectional limiting. When the push head 405 on one side is pulled, the volume of gas between it and the corresponding air brake chamber 404 increases, which reduces the gas pressure. This ensures that when the side is pushed and squeezed again, the gas can move with gradually increasing pressure, ensuring that it can always move with gradually increasing braking strength, thus improving the stability and accuracy of the brake support mechanism 4.

[0044] Please see Figure 3 and Figure 4 The air brake chamber 404 has an upper rectangular and lower conical structure. The lower half of the air brake chamber 404 is a combination of three rectangular channels. The rectangular channel in the middle is perpendicular to the rectangular channels on both sides that are staggered. The rectangular channel at the bottom is connected to the outside. An air injection hole 412 is provided on the inner wall of the upper half of the air brake chamber 404. The air injection hole 412 is connected to the outer side of the brake support plate 401.

[0045] A sliding groove 403 is provided between the two air brake chambers 404. The sliding groove 403 extends out of one side of the brake support plate 401. The push head 405 is slidably disposed inside the sliding groove 403. The sliding groove 403 is connected to the inside of the air brake chamber 404. The push head 405 is fixedly connected to both sides of the sliding groove 403. A shaft is provided between the push head 405 and the brake protrusion 402 to slide and seal with the baffle between the sliding groove 403 and the air brake chamber 404.

[0046] A push rod 406 is fixedly connected to the lower middle part of the push head 405. The push rod 406 is located above one side of the rotating frame 407. The rotating frame 407 is rotatably set inside the central rectangular channel via a rotating shaft. A spring 408 is fixedly connected to the side of the rotating frame 407 opposite to the push rod 406. A strong magnet 409 and a sealing plug 410 are fixedly connected to the lower surface of one half of the rotating frame 407. The sealing plug 410 is located inside the air brake chamber 404. A magnet that is magnetically connected to the strong magnet 409 is set on the lowest rectangular channel. The sealing plug 410 is sealed and inserted into the lower rectangular channel. A vent head 411 is set in the lower rectangular channel.

[0047] First, the overall size of the braking protrusion 301 is larger than that of the braking protrusion 402, ensuring that the braking protrusion 301 can always push the braking protrusion 402 to move when it rotates in an arc. Furthermore, the contact part between the braking protrusion 402 and the braking protrusion 301 can be treated with chamfering, rounding, etc. The specific treatment method is to grind the structure itself, which is a conventional technical means and will not be described in detail here.

[0048] The lower half of the braking protrusion 402 is slightly narrower than the sliding groove 403. When the sliding groove 403 is pushed, it drives the push head 405 and push rod 406 to move synchronously, causing the push rod 406 to gradually move until it contacts the rotating frame 407. Then, the rotating frame 407 is pressed, causing the spring 408 to contract and the powerful magnet 409 and sealing plug 410 to move upward, releasing the seal between the braking support plate 401 and the lowermost rectangular channel. At this time, the compressed gas is discharged to the outside through the rectangular channel and the vent 411, achieving the effect of depressurizing the gas inside the air brake chamber 404. This prevents the gas intensity from continuously increasing during continuous compression, which could cause the braking protrusion 402 to rebound. At this time, the depressurization is achieved, thus achieving the effect of depressurizing the braking support. After the connecting disc 3 is about to stop, and after the braking operation is completed, the braking support disc 401 is removed from the braking range, and the braking protrusion 402 is no longer pushed and is in a pressure-free state. At this time, under the compression and energy storage of the spring 408 and the magnetic attraction of the strong magnet 409, the rotating frame 407 is pushed, pushing the push rod 406 to move in the opposite direction, so that the push head 405 and the braking protrusion 402 are pushed at the same time. Then, the air injection hole 412 is connected to the external air supply equipment to fill the air brake chamber 404 with air. As the gas in the air brake chamber 404 gradually increases, it gradually pushes the braking protrusion 402 to reset. Under the structural limit in the air brake chamber 404, the braking protrusion 402 is pushed to the initial position for the next braking support.

[0049] Among them, the shaft between the pusher 405 and the brake protrusion 402 and the inner flange structure of the air brake chamber 404 are sliding seals to ensure the sealing state of the gas environment. Under the sealing support of the pusher 405 and the air brake chamber 404, and the sealing support of the sealing plug 410, the gas sealing inside the air brake chamber 404 is stable, thereby ensuring that the gas inside can be stably compressed when under pressure and ensuring the stability of the buffer.

[0050] The rotating frame 407 has stepped sides that are not on the same horizontal plane. Supported by the rotating shaft, it is rotatably installed inside the air brake chamber 404. The spring 408 is a strong spring to ensure that the rotating frame 407 can stably push the push rod 406 to move when it is reversed and reset. A corresponding magnetic attraction structure is set in the rectangular channel at the bottom so that the strong magnet 409 can magnetically attract it. This serves two purposes: first, it provides attraction pull for the movement of the rotating frame 407 on this side; second, it provides support for the sealing of the sealing plug 410. The rectangular channel here is equipped with a sealing mechanism that matches the sealing plug 410. It can be a plug-in seal combined with the sealing plug. After the strong magnet 409 is magnetically attracted, it can also prevent the spring 408 from shaking. In the event that the spring 408 shakes, the attraction of the strong magnet 409 can also ensure the accurate sealing position of the sealing plug 410.

[0051] The air injection port 412 is connected to the external air supply device. Since the brake support plate 401 itself moves horizontally in one direction, there will be no rotation problem, which will not affect the stability of the connection between the air injection port 412 and the external air supply device. This part of the air supply connection can be connected to the external air supply device through a pipeline, and the air supply equipment can be selected from existing equipment and is not limited here.

[0052] The braking protrusion 402 provides resistance to the braking protrusion 301. The braking gas intensity can be adjusted by adjusting the gas intensity inside the air brake chamber 404, adjusting the length of the push rod 406 and the push head 405 to adjust the moving distance, and adjusting the moving distance of the braking protrusion 402. This adjustment method and the final corresponding intensity setting can be tested and adjusted according to different specifications of five-axis swing heads. This testing and adjustment method is well-known technology in the field. The time and intensity of air injection into the air brake chamber 404 through the air injection hole 412 can be automatically controlled by existing system logic and adjusted according to the simulation before the product is officially used to ensure the stability of this part. The specific operation method is well-known technology in the field and will not be described in detail here.

[0053] Based on the position of the air injection hole 412, a spring 408 of appropriate strength is set so that when the push rod 406 and the push head 405 spring back to their original position, the air injection hole 412 can be leaked out, ensuring stable air injection. With the support of the gas in the air brake chamber 404 on the other side, it can prevent the braking protrusion 402 and the push head 405 from colliding with the inner wall of the air brake chamber 404 due to excessive spring force of the spring 408, ensuring its stability and safety during reset movement. Here, a spring 408 of appropriate strength can be selected through simulation. Example

[0054] Please see Figure 5 - Figure 8 In this embodiment, an anti-tangle mechanism includes a covering mechanism 5, which is disposed at the wire harness connection point of the five-axis swing head body 1.

[0055] The covering mechanism 5 includes a covering pad 501 for overall positioning, a positioning frame 504 for individual positioning, and a first fastening band 502 and a second fastening band 503 for continuous locking. The positioning frames 504 located inside the covering pad 501 are used in pairs symmetrically, and the positioning frames 504 located outside the covering pad 501 are used in a single horizontal array.

[0056] First, insert the wire harness between the two positioning frames 504. Then, insert the first fastening band 502 into the positioning frames 504 in sequence to limit the wire harness between the positioning frames 504, the first fastening band 502 and the covering pad 501. By pulling the first fastening band 502 in sequence, the individual wire harness can be fastened and limited. Alternatively, the first fastening band 502 can be inserted into the positioning frames 504 in sequence first, leaving space for the wire harness to be inserted between the two positioning frames 504.

[0057] By first connecting the first fastening band 502 on the same vertical column to the first positioning frame 504, then placing the wire harness between the two positioning frames 504 in the first group, and then pulling the first fastening band 502 to connect it to the positioning frame 504 on the other side of the group, and then operating the positioning frame 504 and the first fastening band 502 on the same side of the wire harness in sequence, and then repeating the operation on the next wire harness, the effect of sequential positioning of multiple limit positions is achieved. In addition, when fixing, it also has the function of isolating adjacent wire harnesses, thus preventing the wire harness from being misaligned and twisted due to the rotation of the device.

[0058] After fixing the wire harness in sequence, the covering pad 501 is rolled up to make it coiled up. Then, with the cooperation of the second fastening band 503 on the outside and the positioning frame 504, the two ends of the covering pad 501 are pulled and fastened from the outside, forming a double fastening effect on the inside and outside of the covering pad 501, further preventing the wire harness from getting tangled.

[0059] Depending on the number of wire harnesses to be secured, appropriate specifications of covering pads 501 and a corresponding number of first fastening straps 502 can be selected to lock single-strand, two-strand, and multi-strand wire harnesses. When a connector is used for a single-strand wire harness and the connector needs to be protected and positioned, the wire harnesses on both sides can be internally positioned after the connector is installed and then fastened from the outside. Compared with the traditional plastic collar heat fusion method, it has the effect of convenient use and reduces the required equipment, thus enabling the device of this application to be used in a variety of specifications.

[0060] The entire covering mechanism 5 can be made of flexible materials, such as plastic, while possessing a certain tensile strength, ensuring its tensile strength while allowing it to be deformed and used.

[0061] Please see Figure 7 and Figure 10 The positioning frame 504 is provided with positioning small teeth 5041 and positioning large teeth 5042 for limiting support. The positioning small teeth 5041 and positioning large teeth 5042 are distributed in a staggered and symmetrical manner.

[0062] First, the overall volume of the positioning small tooth 5041 is smaller than that of the positioning large tooth 5042, and the overall volume of the fastening small tooth 5021 is smaller than that of the fastening large tooth 5022. The fastening small tooth 5021 works in conjunction with the positioning small tooth 5041, and the fastening large tooth 5022 works in conjunction with the positioning large tooth 5042. The initial contact positions of the positioning small tooth 5041 and the fastening small tooth 5021 are both arc-shaped inclined surfaces. Due to their flexible structure, they can undergo directional deformation and move to the other side of the positioning small tooth 5041. Then, under the contact limitation of the vertical surface of the positioning small tooth 5041 and the vertical surface of the fastening small tooth 5021, the strength of their structure creates a positioning and limiting effect, preventing the first fastening band 502 from moving back and unlocking. The initial contact positions of the positioning tooth 5042 and the fastening tooth 5022 are both arc-shaped inclined surfaces. Based on the flexibility of their structure, they can guide deformation, causing the fastening tooth 5022 to move to the other side of the positioning tooth 5042. Then, under the contact limitation of the vertical surface of the other side of the positioning tooth 5042 and the vertical surface of the other side of the fastening tooth 5021, and based on the strength of their structure, they produce a positioning restriction effect, preventing the first fastening band 502 from moving back and unlocking. This provides a double limiting effect for the first fastening band 502. Furthermore, based on the inconsistent size of their corresponding limiting structures, they have deformation space during winding and compression without affecting their limiting strength, preventing the locking position from easily breaking when deformation occurs due to the consistent size of both sides.

[0063] Secondly, the second fastening band 503 has the same overall structure as the outer side of the first fastening band 502, both of which are provided with corresponding fastening small teeth 5021 and fastening large teeth 5022. The fastening small teeth 5021 and fastening large teeth 5022 are also symmetrically staggered. The fastening small teeth 5021 and fastening large teeth 5022 themselves are evenly distributed in an array to ensure their compatibility.

[0064] Please see Figure 7 and Figure 10 One end of the first fastening band 502 is provided with a positioning component 506 for fixing;

[0065] The positioning component 506 includes an auxiliary frame 5061 and a positioning bolt 5068. A first fastening band 502 passes through the auxiliary frame 5061. The auxiliary frame 5061 is provided with auxiliary small teeth 5062 and auxiliary large teeth 5063 that are symmetrically staggered. The first fastening band 502 is provided with a number of fastening small teeth 5021 and fastening large teeth 5022 evenly on both sides. The auxiliary small teeth 5062 are used for positioning the fastening small teeth 5021, and the auxiliary large teeth 5063 are used for positioning the fastening large teeth 5022.

[0066] A rotating ring 5065 is fixedly sleeved on the outer side of the lower end shaft of the auxiliary frame 5061. A rotating head 5064 is fixedly connected to the upper end of the positioning bolt 5068. A rotating groove 5066 for limiting the rotation of the rotating ring 5065 is provided inside the rotating head 5064. A positioning pad 5067 passes through the positioning bolt 5068. The positioning pad 5067 is located between the lower surface of the rotating head 5064 and the upper surface of the second fastening band 503.

[0067] First, the first fastening band 502 and the positioning bolt 5068 are uniformly and symmetrically thinned at the penetration position and adapted to the specifications of the lower surface of the positioning pad 5067. The lower surface of the positioning pad 5067 has a circular groove and an arc-shaped groove through the outer side, forming a rectangular and circular connecting groove, which provides a corresponding limiting effect for the first fastening band 502 and provides a fixed-point connection effect for the first fastening band 502. One end of the second fastening band 503 is also treated in the same way and can be connected to the positioning bolt 5068 accordingly.

[0068] With the corresponding support of the auxiliary small tooth 5062 and the auxiliary large tooth 5063 within the auxiliary frame 5061, and with the overall volume of the auxiliary small tooth 5062 being larger than that of the auxiliary large tooth 5063, a support effect equivalent to that of the positioning frame 504 is formed. This provides double-sided unidirectional limiting for both the first fastening band 502 and the second fastening band 503, preventing the first fastening band 502 and the second fastening band 503 from moving and slipping in the opposite direction.

[0069] The positioning component 506 and the positioning bolt 5068 can be installed on the same side or different sides of the covering pad 501 along with the first fastening band 502. When installed on the same side, they are positioned inside the rolled covering pad 501. When installed on different sides, they are positioned on the outside of the rolled covering pad 501, where the extended first fastening band 502 is positioned. The second fastening band 503 is installed on the same side as the positioning component 506 and the positioning bolt 5068 to ensure the stability of the fastening limit.

[0070] Then, the positioning pad 5067 and the first fastening band 502 are connected through the positioning bolt 5068 and then fastened and limited by the positioning bolt 5068. By rotating the rotating head 5064, the positioning pad 5067 and the first fastening band 502 are adapted and positioned. Then, by continuously rotating the rotating head 5064, the positioning pad 5067 and the first fastening band 502 are fastened and limited, so as to achieve the effect of positioning the first fastening band 502. Under the sliding support of the rotating ring 5065 and the rotating groove 5066, it is ensured that the rotating head 5064 and the auxiliary frame 5061 can rotate relative to each other without affecting the fastening rotation of the positioning bolt 5068 and the angle adjustment of the auxiliary frame 5061.

[0071] The positioning component 506 is positioned at one end of the first fastening band 502 and the second fastening band 503 when they are stationary. At this time, that end of the first fastening band 502 or the second fastening band 503 is positioned. When equipment maintenance is required, the wiring harness needs to be untied, and the positioning pin 5068 is moved out by reversing the rotating head 5064, contacting the first fastening band 502 or the second fastening band 503 in its positioned state. At this time, the other end of the first fastening band 502 or the second fastening band 503 may be inserted and limited by the auxiliary frame 5061. Then, simply pull the unpositioned first fastening band 502 or the second fastening band 503. One end of the fastening strap 503 causes the first fastening strap 502 or the second fastening strap 503 to move toward the side that is not restricted, until the first fastening strap 502 or the second fastening strap 503 is completely disengaged from the positioning frame 504 or the auxiliary frame 5061, thereby achieving the effect of releasing the restriction on the entire wire harness or covering pad 501. At this point, it is only necessary to pull out the first fastening strap 502 or the second fastening strap 503, without cutting it. Compared with the use of limiting components such as transmission cable ties, plastic film, and plastic tubes, it has the effect of being reusable and cost-saving, and the bundling and positioning state is more aesthetically pleasing and reasonable.

[0072] Please see Figure 5 Several first fastening bands 502 located inside the covering pad 501 are arranged in an inclined array. Several positioning frames 504 located at the same inclination are grouped together, and multiple groups of positioning frames 504 are arranged in a vertical array. Positioning frames 504 located at the same vertical position are used for locking the same wire harness.

[0073] Several positioning frames 504 located on the outside of the covering pad 501 are arranged in a horizontal equidistant array. Several positioning frames 504 located on the same horizontal array line form a group. The outer surfaces of the outer sides of the covering pad 501 are provided with a second fastening band 503 and a positioning frame 504 at opposite ends.

[0074] By setting multiple sets of positioning frames 504 to an inclined state, after being rolled up, the multiple sets of positioning frames 504 are distributed in a three-dimensional spiral shape, with the internal positioning frames 504 located on different horizontal planes, preventing them from piling up on the same horizontal plane and causing the overall diameter to become too bulky. The second fastening band 503 is also used in an inclined state, which can increase its contact area with the wire harness, thereby increasing its fastening strength to the wire harness. With the setting of multiple sets of inclined positioning frames 504 and the first fastening band 502, the overall fastening strength of the device is improved.

[0075] Multiple equidistant positioning frames 504 provide positioning for the fastening of the second fastening band 503, ensuring uniformity of fastening and providing stable fastening strength for both ends of the outer side of the covering pad 501, preventing slippage and detachment on both sides. Based on the arrangement of the positioning frames 504 on the outer side of the covering mechanism 5 and the second fastening band 503, the covering pad 501 can simultaneously achieve the effect of end edge fastening when fastening two strands or a small number of wires, preventing slippage on both sides. When covering and protecting a single-strand connector, positioning and fastening can also be performed simultaneously. At the same time, it is convenient to pull out the second fastening band 503 for reuse, achieving the effect of reusability.

[0076] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0077] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
