Description

Technical Field

[0001] The present invention relates to the technical field of positioning and punching of armbands, and more particularly to an automatic punching device for an armband and shoulder badge with positioning function. Background Art

[0002] Automatic punching equipment for epaulettes and armbands is widely used in apparel manufacturing and uniform accessories. This is particularly true for epaulettes and armbands made of metal or synthetic fiber materials, which require precise holes for subsequent installation of connectors. This equipment uses laser drilling technology to automate the positioning and punching process, automatically adjusting the hole spacing and diameter based on a preset template, reducing manual error and meeting standardized production requirements. It can be applied to large-scale uniform production to ensure product dimensional accuracy and consistency.

[0003] Especially for multi-layered metal epaulettes and armbands, during the laser drilling process, the high temperature of the laser will cause the material to partially melt and then solidify, forming a hardened layer or a carbonized layer in the hole wall, resulting in rough hole walls, affecting the subsequent fastener connection strength. In the existing technology, a switching module or a coupling structure is usually used to integrate a mechanical drill bit for secondary trimming to remove the hardened layer and burrs in the wall, restore the smoothness of the hole wall and ensure uniform force. The drill bit can be rotated immediately after laser drilling to perform cutting. Although this design reduces the process time, it is easy to cause mis-touch or base point offset during the reciprocating switching process, resulting in inaccurate processing positioning or poor coordination, and it is difficult to completely eliminate the influence of the carbonized layer.

[0004] Its main drawback is the mutual interference of highly integrated modules. When laser drilling and mechanical drill bits are placed on a single component, factors generated when a single module is working, such as high temperature of the laser or mechanical vibration of the rotating drill bit, will be transmitted to the other module, causing thermal deformation or vibration displacement, seriously affecting the accuracy of coordinated cooperation. Fundamentally, the contradiction that existing technologies cannot solve is that the coupling of the physical space of the modules limits the performance of independent functions, and the error of the switching mechanism itself aggravates the problem of inconsistent base points. This defect will lead to unstable processing quality, inaccurate installation of connectors and other consequences. Summary of the Invention

[0019] Compared with the prior art, the above technical solution provided by the present invention has at least the following beneficial effects:

[0020] (1) This solution eliminates physical interference between modules and improves drilling accuracy and coordination efficiency through the coaxial laser drilling and hole wall processing mechanisms. In order to solve the base point offset problem caused by the coupling of laser drilling and mechanical drill bits in the background technology, a U-shaped placement frame and a multi-axis servo robot arm are used to place the laser drilling head on the upper side of the epaulette and the hole wall processing mechanism on the lower side. The first linear servo motor is used to ensure that the two work coaxially and independently, without the need for module switching or displacement, thus avoiding thermal deformation and vibration transmission. This not only solves the coordination error caused by spatial coupling in the existing technology, but also ensures the positioning consistency of drilling and trimming, significantly improving the stability of processing quality, and is particularly suitable for the precision drilling needs of metal or synthetic fiber epaulettes.

[0021] (2) Through the coordination of the rotary hole wall processing mechanism and the gas-liquid supply unit, efficient cleaning and dynamic cooling of the hole wall hardening layer are achieved. Different from the single trimming method of the traditional mechanical drill bit, the configured hole wall processing mechanism integrates the fillet cleaning unit and the resettable embedded grinding airbag. Driven by the servo motor, the rotating cover unit drives the double-sided fillet sleeve to scrape the carbonized layer of the hole wall. At the same time, the embedded air duct blows away debris or adsorbed residues through the two-way air duct generated by the guide vane. During the working process, the resettable embedded grinding airbag expands and fits the hole wall after inflation, performs secondary liquid distribution grinding, and covers the spray cooling lubricant through the atomizing spray port. The dynamic combination solves the hole wall hardening problem caused by the high temperature of the laser, avoids the positioning error of the secondary trimming, and at the same time, the air duct cooling reduces the heat impact and improves the hole wall smoothness and the installation strength of the connector.

[0022] (3) By integrating the purification collection unit with the air duct circulation system, the processing environment is further optimized and the equipment sustainability is improved. To address the interference problem of smoke and debris generated by laser drilling, an inclined bottom plate and a purification collection unit are configured at the bottom of the hole wall processing mechanism. The activated carbon cavity adsorbs smoke, and the inclined guide plate collects debris. The air duct system controls the wind direction through the guide vanes of the gas-liquid supply unit. In the adsorption mode, the drilling area is cooled and the oil mist is purified to ensure that the active surface of the laser drilling head is clear. During operation, the design also supports adsorption purification close to the smoke source to reduce energy consumption. Compared with existing technologies, this integrated solution organically combines drilling, trimming and waste management, reduces maintenance frequency, improves processing stability and environmental protection, and is particularly suitable for the automation needs of large-scale epaulette production.

[0046] The following describes in detail, with reference to the accompanying drawings and specific embodiments, a positioning-based automatic punching device for shoulder and armbands provided by the present invention. It is also noted that, for the sake of completeness, the following embodiments are best and preferred embodiments, and those skilled in the art may employ alternative implementations for known techniques. Furthermore, the accompanying drawings are provided solely for the purpose of illustrating the embodiments in greater detail and are not intended to limit the present invention.

[0047] like Figures 1 to 13 As shown, an embodiment of the present invention provides an automatic punching device for epaulettes and armbands with positioning, comprising a U-shaped placement frame 1 and a multi-axis servo robotic arm 4. Servo crawler groups 2 are arranged on both sides of the upper surface of the U-shaped placement frame 1 for conveying epaulettes, and multi-axis servo clamping arms 3 for clamping the epaulettes conveyed into place are fixedly installed on both sides of the U-shaped placement frame 1. The multi-axis servo robotic arm 4 is arranged at the opposite ends of the U-shaped placement frame 1, and two upper and lower groups of first linear servo motors 5 are fixedly installed on the output end. The first linear servo motor 5 on the upper side of the multi-axis servo robotic arm 4 is located on the upper side of the U-shaped placement frame 1 as a whole, and a laser drilling head 6 is fixedly installed on the output end. The first linear servo motor 5 on the lower side of the multi-axis servo robotic arm 4 is located on the lower side of the U-shaped placement frame 1 as a whole, and a hole wall processing mechanism 7 is fixedly installed on the output end, and the laser drilling head 6 and the hole wall processing mechanism 7 are coaxial up and down;

[0048] The hole wall processing mechanism 7 includes a cylindrical cover 71 and a servo motor 73 fixedly installed at the center of the bottom of the cylindrical cover 71. The top of the cylindrical cover 71 is correspondingly provided with a rotating cover unit 10 to rotate along with the rotation of the output end of the servo motor 73.

[0049] Among them, the rotating cover unit 10 includes a cylindrical sleeve cover 101, and an axial light feedback module 103 corresponding to the upper and lower parts of the laser drilling head 6 and a second linear servo motor 106 located on the radius end of the cylindrical sleeve cover 101 are arranged at the center position of the upper surface of the cylindrical sleeve cover 101. A rounded corner cleaning unit 11 for scraping the hole wall is provided at the output end of the second linear servo motor 106.

[0050] In order to solve the problem of coordinated interference between the laser module and the mechanical drill module in the existing epaulette and armband laser drilling equipment caused by physical space coupling, and the core contradiction of inaccurate secondary trimming positioning caused by this, the above-mentioned technical solution is now adopted to solve the problem. The above-mentioned technical solution is mainly composed of a U-shaped placement frame 1, a servo crawler group 2, a multi-axis servo clamping arm 3, a multi-axis servo mechanical arm 4, a first linear servo motor 5, a laser drilling head 6, and a hole wall processing mechanism 7. The U-shaped placement frame 1, the servo crawler group 2, and the multi-axis servo clamping arm 3 constitute the epaulette and armband conveying end of the device. During operation, the servo crawler group 2 on both sides of the U-shaped placement frame 1 performs synchronous conveying through the control program of the servo group, and conveys the epaulette and armband placed on its surface to the specified position, and then the multi-axis servo clamping arm 3 on both sides contracts inward, and presses the epaulette and armband through one end of the soft rubber head to ensure that the epaulette and armband will not move or shake during subsequent processing. The entire structure is a conventional configuration for conveying components in the existing technology. The configured axial optical feedback module 103 is a conventional photosensitive module. During operation, it detects laser light directed at its surface and provides feedback to the laser drilling head 6, enabling the system to determine in real time whether the laser drilling head 6 has penetrated the surface of the target epaulette or armband, ensuring the thoroughness of the laser drilling head 6's drilling. The configured multi-axis servo robotic arm 4 is structurally identical to the multi-axis servo clamping arm 3, both of which are conventional robotic arm structures capable of moving on a multi-axis output end. Controlled by a servo program, they are positioned at opposite ends of the U-shaped mounting frame 1 and are used to adjust the position of the first linear servo motor 5 at its output end on the epaulette or armband. The configured laser drilling head 6 is a conventional device for laser engraving and drilling. The first linear servo motor 5, located at the output end of the multi-axis servo robotic arm 4, comprises two relatively independent structures, one above and one below, controlling the vertical movement of the output end device. This ensures that the upper and lower mechanisms operate coaxially while maintaining mutual non-interference.

[0051] Among them, the hole wall processing mechanism 7 serving as the collaborative end mainly includes a cylindrical cover 71 and a servo motor 73. During operation, the rotating cover unit 10 is driven by the output end of the servo motor 73 to rotate on the top of the cylindrical cover 71. During the rotation, on the one hand, an air duct is generated to assist the laser drilling head 6 to work, and on the other hand, the rounded corner cleaning unit 11 is controlled to scrape and clean the hole wall. Under the premise of the coaxial and non-interference working of the upper and lower mechanisms, the collaborative interference problem caused by the physical space coupling between the laser module and the mechanical drill head module in the existing epaulette and armband laser drilling equipment can be effectively solved.

[0052] like Figures 1 to 13 As shown, the rounded corner cleaning unit 11 includes a bilateral rounded corner sleeve block 111, the outer edge of the bilateral rounded corner sleeve block 111 is a rounded arc edge, and the two side ends of the rounded arc edge are fixedly connected with a cut rounded edge 112, and the inner sides of the bilateral rounded corner sleeve 111 are provided with embedded air ducts 113, and the embedded air duct 113 on each side is respectively communicated with the cut rounded edge 112 on the same side, and the cut corner of the cut rounded edge 112 is tangent to the inner wall of the embedded air duct 113 to guide the air without obstruction.

[0053] Among them, the configured rounded corner cleaning unit 11 is a special-shaped grinding block, which is different from the grinding rotor in the prior art. The overall structure is a T-shaped scraper block with a rounded arc edge on the outer side, and a cutting rounded corner edge 112 is fixedly connected to both sides of the rounded corner edge of the bilateral rounded corner sleeve 111. During the working process, the impurities and the solidified layer on the buckle wall are scraped off through the cutting rounded corner edges 112 on both sides, and the internal sides of the bilateral rounded corner sleeve 111 are provided with embedded air ducts 113, and the embedded air ducts 113 are used to transport air to the cutting rounded corner edges 112 on both sides, and the air ducts not only refer to the outward blowing air ducts, but also refer to the reverse adsorption air ducts.

[0054] like Figures 1 to 13 As shown, the interior of the cylindrical cover 71 is configured with a gas-liquid supply unit 8 for providing air to the embedded air duct 113, and the gas-liquid supply unit 8 includes a liquid storage cylindrical tank 81 fixedly mounted on the output end of the servo motor 73, and a plurality of air guide vanes 83 are fixedly mounted on the outer circumferential surface of the liquid storage cylindrical tank 81, and an outer open-shaped air collecting hood 104 is fixedly mounted at the center position of the inner bottom circle of the cylindrical sleeve cover 101, and a first dual-channel duct 1011 is connected to the outer open-shaped air collecting hood 104 through the axial light feedback module 103 at the center position of the upper surface of the cylindrical sleeve cover 101, and the protruding end of the first dual-channel duct 1011 is connected to the double-sided rounded sleeve block 111 to supply the air duct, and a plurality of leakage holes are opened on the surface of the cylindrical sleeve cover 101 to cooperate with the reverse rotation of the air guide vanes 83 to absorb debris on the surface, and a removable side cover 74 is installed on the side wall of the cylindrical cover 71.

[0055] The gas-liquid supply unit 8 has two functions. First, the liquid storage cylinder 81 rotates within the cylindrical cover 71 through the drive control of the servo motor 73 output terminal, using several air guide vanes 83 on the outer surface of the liquid storage cylinder 81. This drives the outer air guide vanes 83 to rotate, and the clockwise and counterclockwise rotations control the wind direction within the cylindrical cover 71. The cylindrical cover 101 is movably mounted on the top of the cylindrical cover 71 and rotates synchronously with the rotation of the liquid storage cylinder 81.

[0056] like Figures 1 to 13 As shown, the fillet cleaning unit 11 also includes a reserved opening 114 opened at the middle position inside the bilateral fillet sleeve 111, and an embedded clamping block 115 is fixedly installed in the reserved opening 114, and a resettable embedded polishing airbag 116 that can extend toward the outer arc edge of the bilateral fillet sleeve 111 is fixedly installed in the embedded clamping block 115, and a plurality of atomizing spray ports 117 are fixedly installed on the outer protruding surface of the resettable embedded polishing airbag 116, an electric-controlled pump is arranged at the center position of the upper surface of the liquid storage cylinder 81, and an upward-extending sealing joint 84 is fixedly installed on the output end of the electric-controlled pump, an inner axial liquid guide tube 105 fixedly connected to the sealing joint 84 is fixedly installed at the inner center position of the externally open air collecting hood 104, and a second dual-channel conduit 12 is separately connected to the outer side of the embedded clamping block 115.

[0057] The resettable inline polishing airbag 116 is a conventional airbag structure capable of expanding outward when inflated. When the internal gas is sucked out, it returns to its original state, i.e., retracts into the interior of the reserved sleeve 114. After the resettable inline polishing airbag 116 is inflated and expanded, the outer polishing coating protrudes outward to adhere to the surface to be processed for secondary processing. The configured externally open air collecting hood 104 and the inner axial liquid guide tube 105 are integrally formed, forming a double-layered hollow conduit structure. The inner axial liquid guide tube 105 at the inner axial end is used, on the one hand, to guide liquid outward to assist in the injection and polishing of the polished convex surface of the resettable inline polishing airbag 116. On the other hand, the inner axial liquid guide tube 105 at the inner axial end also serves as a connecting frame, connecting the liquid storage cylinder 81 and the cylindrical sleeve cover 101 vertically, and transferring the driving force generated by the output end of the servo motor 73 to the cylindrical sleeve cover 101.

[0058] like Figures 1 to 13As shown, the inflation end of the resettable embedded polishing airbag 116 is provided with a separate inflation connector, and several atomizing spray ports 117 on the resettable embedded polishing airbag 116 are connected in series through a single conduit, and the second dual-channel conduit 12 includes a main channel conduit 121 connected to the inflation connector of the resettable embedded polishing airbag 116, and several skeleton-type separating rings 122 are fixedly installed on the inner wall of the main channel conduit 121, and a secondary channel conduit 123 is fixedly installed inside the main channel conduit 121 through the skeleton-type separating ring 122, and the secondary channel conduit 123 is connected to a single conduit connected in series with several atomizing spray ports 117, and several reserved leaks 124 are opened in a circular manner on the skeleton-type separating ring 122.

[0059] Among them, the configured resettable embedded polishing airbag 116 is provided with a separate inflation connector for connecting to control its inflation state, and several atomizing spray ports 117 arranged on the resettable embedded polishing airbag 116 are connected in series through a single conduit. It only needs to be connected to the single conduit to supply liquid to each atomizing spray port 117. The inflation connector for controlling its inflation state and the two ends of each atomizing spray port 117 in series do not affect each other and work independently. The configured second dual-channel conduit 12 has the same structure as the first dual-channel conduit 1011, and both are double-layer cavity conduits.

[0060] like Figures 1 to 13 As shown, a limiting groove 108 is provided on the surface of the cylindrical sleeve cover 101 at a position on the upper side of the second linear servo motor 106, and a card cover 107 is fixedly installed on the output end of the second linear servo motor 106, and a ring block 109 that slides and is stuck in the limiting groove 108 is fixedly installed on the upper surface of the card cover 107, and a cavity rod 1010 is fixedly installed on the upper surface of the ring block 109, and the double-sided rounded corner block 111 is fixedly installed on the upper side of the cavity rod 1010, and the cavity of the cavity rod 1010 is communicated with the embedded air duct 113 on the double-sided rounded corner block 111, and a movable cover is fixedly installed at the bottom edge position of the cylindrical sleeve cover 101 with a sealing groove edge 102 on the upper side of the cylindrical cover 71, and a sealed liquid replenishment inlet 82 is fixedly installed on the side of the liquid storage cylinder tank 81.

[0061] The second linear servo motor 106 has the same structure as the first linear servo motor 5, and is a conventional structure capable of servo movement at a linear output end. It controls the output end's card cover 107, which moves back and forth along a limiting slot 108, extending outward from the center of the cylindrical sleeve cover 101. The extension length is controlled by a servo program. In actual operation, the fillet cleaning unit 11 is required to fit closely against the inner wall of the buckle. The sidewall of the cylindrical cover 71 is equipped with a removable side cover 74, which allows for replenishment of liquid into the sealed refill port 82 of the liquid storage cylinder 81.

[0062] like Figures 1 to 13 As shown, the structure of the first dual-channel duct 1011 is the same as that of the second dual-channel duct 12, and the first dual-channel duct 1011 is provided with a duct with the same function as the main channel duct 121 to fill the air duct generated at the position of the external open-shaped wind collecting hood 104 into the cavity of the cavity rod 1010, and into the main channel duct 121 of the second dual-channel duct 12, and an electric control valve is provided at the position of the main channel duct 121 of the second dual-channel duct 12 to select whether to fill the air duct into the resettable embedded polishing airbag 116; the first dual-channel duct 1011 is provided with a duct with the same function as the secondary channel duct 123 to be connected to the inner axial liquid guide tube 105, and to communicate with the secondary channel duct 123 in the second dual-channel duct 12.

[0063] The structure of the first dual-channel conduit 1011 is the same as that of the second dual-channel conduit 12, and the specific connection states are as follows:

[0064] The outer open-shaped wind collecting hood 104 and the inner axial liquid guide tube 105 are an integrated structure. The cavity formed between the outer open-shaped wind collecting hood 104 and the inner axial liquid guide tube 105 is used to guide the air duct generated inside the cylindrical hood 71, and the first dual-channel duct 1011 is equipped with a duct with the same function as the main channel duct 121 to fill the air duct generated at the position of the outer open-shaped wind collecting hood 104 into the cavity of the cavity rod 1010, that is, the air duct is transported through the cavity formed between the main channel duct 121 and the secondary channel duct 123 configured in the first dual-channel duct 1011, and the inner axial liquid guide tube 105 is used to transport liquid. The first dual-channel duct 1011 is equipped with a duct with the same function as the secondary channel duct 123 to be connected to the inner axial liquid guide tube 105 to transfer and transport the reagent in the liquid storage cylindrical tank 81, and communicate with the secondary channel duct 123 in the second dual-channel duct 12. As for the second dual-channel duct 12, the main channel duct 121 of the second dual-channel duct 12 is connected to the inflation joint of the resettable embedded polishing airbag 116, and the other side is exposed to the inner cavity of the cavity rod 1010. Because the duct with the same function as the main channel duct 121 configured in the first dual-channel duct 1011 will fill the air duct into the cavity of the cavity rod 1010, the main channel duct 121 side of the second dual-channel duct 12 can also use the air duct, and the secondary channel duct 123 of the second dual-channel duct 12 is connected to a single duct of several atomizing spray ports 117 connected in series, and the other side is connected to the secondary channel duct 123 in the first dual-channel duct 1011, supplying the transported liquid to the atomizing spray port 117.

[0065] like Figures 1 to 13 As shown, an inclined bottom plate 72 is fixedly installed on the inner bottom of the cylindrical cover 71. The inclined bottom plate 72 and the cylindrical cover 71 are an integral structure, and the inclined bottom plate 72 as a whole is an inclined surface structure inclined from the center end of the cylindrical cover 71 to the outer edge, and a screw groove 76 is fixedly installed on the outer inclined end of the inclined bottom plate 72. The surface of the screw groove 76 is circumferentially provided with a plurality of leaks 75, and the bottom of the screw groove 76 is provided with a purification collection unit 9.

[0066] like Figures 1 to 13 As shown, the purification collection unit 9 includes a circular sleeve 91, and a sealing ring edge 92 is fixedly installed on the upper surface of the circular sleeve 91. The circular sleeve 91 is rotatably installed on the bottom of the screw groove 76 through the sealing ring edge 92. An inclined guide plate 93 is fixedly connected to the middle position of the interior of the circular sleeve 91, and the interior of the circular sleeve 91 is divided into two upper and lower cavities by the inclined guide plate 93.

[0067] like Figures 1 to 13As shown, the cavity on the upper side of the inclined guide plate 93 is used to collect debris, and the cavity on the lower side of the inclined guide plate 93 is used to place activated carbon, and the side walls of the upper and lower cavities separated by the inclined guide plate 93 are fixedly installed with unloading and feeding sealing ports 95, and a plurality of air leakage ports 94 are opened on the surface of the inclined guide plate 93.

[0068] Among them, the configured purification and collection unit 9 cooperates with the inclined bottom plate 72 at the bottom of the cylindrical cover 71 to work. The servo motor 73 controls the rotation of the liquid storage cylindrical tank 81 at the output end to generate a reverse air duct, so that the surface of the cylindrical sleeve cover 101 produces an adsorption air duct, and the debris remaining on the upper surface of the cylindrical sleeve cover 101 will be sucked into the interior of the cylindrical cover 71. The internal debris sucked into the cylindrical cover 71 falls into the annular sleeve 91 of the purification and collection unit 9 through the inclined bottom plate 72 and the leakage 75 on the side wall of the inclined bottom plate 72, and is stored in the cavity on the upper side of the oblique guide plate 93 of the annular sleeve 91. The activated carbon stored in the cavity on the lower side of the annular sleeve 91 oblique guide plate 93 can absorb the smoke generated when the laser drilling head 6 punches the epaulettes during the process of generating the adsorption air duct inside the cylindrical cover 71. In the process of absorbing the smoke, the first linear servo motor 5 can also be cooperated with to lift the hole wall processing mechanism 7 as a whole to be close to the smoke generating end. In the process of purifying the smoke by the activated carbon in the cavity on the lower side of the oblique guide plate 93, the debris in the cavity on the upper side of the annular sleeve 91 oblique guide plate 93 can also be synchronously purified to facilitate subsequent processing. On the other hand, when close to During the adsorption process at the smoke generating end, the air duct can also drive the rounded corner cleaning unit 11 at one end of the cavity rod 1010 on the upper side of the rotating cover unit 10 to generate an adsorption air duct. By simply controlling the cavity rod 1010 to be located outside through the second linear servo motor 106, the oil mist can also be adsorbed outside the processing end. The adsorption process can effectively remove the interference of the oil mist on the laser drilling head 6, ensuring the clarity of the active end surface of the laser drilling head 6 during the drilling process. The air duct is also used to effectively cool the inner wall of the hole, further ensuring stability for subsequent processing. The configured purification collection unit 9 is entirely detachable and has a circular ring structure, which does not interfere with the normal operation of the servo motor 73.

[0069] The specific working principle of the configured rounded corner cleaning unit 11 is as follows:

[0070] First, after fixing the epaulettes to be processed on the U-shaped placement rack 1 according to the above operations, the laser drilling head 6 at the output end of the multi-axis servo robot arm 4 is aligned with the punching end through the servo control program to perform laser drilling. During the drilling process, the first linear servo motor 5 on the lower side enables the purification collection unit 9 to cooperate with the rotating gas-liquid supply unit 8 to generate an adsorption air duct to cool and purify the area.

[0071] Then, through the servo control of the second linear servo motor 106, the card cover 107 at the output end drives the cavity rod 1010 on the ring block 109 to move precisely in the limiting slide groove 108, and the fillet cleaning unit 11 outside the cavity rod 1010 is attached to the inner wall of the hole. At this time, the servo motor 73 is turned on again. Different from the difference in generating the adsorption air duct mentioned above, the reverse rotation at this time generates an outward blowing air duct. The air duct enters the fillet cleaning unit 11 through the first dual-channel duct 1011. On the one hand, it is poured into the resettable embedded polishing airbag 116 to make the resettable embedded polishing airbag 116 expand and expand, protruding the polishing coating on the outer surface outward. On the other hand, it is poured into the embedded air ducts 113 on both sides of the bilateral fillet sleeve 111, so that the scraping ends on both sides can also synchronously blow away the residual debris in the area.

[0072] Then, after the initial treatment is completed, the fillet cleaning unit 11 is moved away by the second linear servo motor 106, so that the fillet cleaning unit 11 is at a distance from the inner wall of the hole. At this time, the pump on the upper side of the liquid storage cylinder 81 is turned on, and the liquid in the liquid storage cylinder 81 is transported to the atomizing spray port 117 through the conduit. The atomizing spray port 117 then sprays the inner wall of the hole 360 ​​degrees. The configured liquid is a cooling lubricating liquid in the prior art. After the spraying, the resettable embedded polishing airbag 116 is protruded outward, and the second linear servo motor 106 is used to make the resettable embedded polishing airbag 116 stick to the inner wall of the hole. The servo motor 73 is used to control the rotation of the gas-liquid supply unit 8, and the 360-degree rotation of the secondary liquid distribution cleaning is carried out synchronously. During this process, the air duct can continue to be generated from the position of the embedded air duct 113 by the rotation of the guide vane 83 to quickly dry out the residual liquid.
