Description

Technical Field

[0001] This invention relates to the field of special glass drilling technology, specifically a drilling device for special glass processing. Background Technology

[0002] Specialty glasses, such as high-strength tempered glass, high-hardness bulletproof glass, brittle optical glass, ultra-thin display glass, composite laminated glass, and microcrystalline glass, are widely used in high-tech fields such as aerospace, high-end buildings, optical instruments, electronic information, and security protection due to their excellent physical and chemical properties (such as high strength, high hardness, high light transmittance, and specific electrical or thermal properties). In these applications, high-precision, high-quality drilling is often required for special glass to complete installation, connection, ventilation, or functional integration. Existing drilling devices, such as the tempered glass processing anti-crack drilling device disclosed in CN218314446U, include an operating table and an anti-crack component. The operating table has bases installed on both sides of its lower end, and a support rod is fixed near the edge of the upper end of the operating table. The anti-crack component for preventing cracking during tempered glass drilling is located inside the support rod, and the anti-crack component includes a fixed rod, a groove, a slider, a fixed frame, a pneumatic rod, a fixed ring, a water pipe, and a drill bit. The fixed rod has a groove inside, and a slider is connected inside the groove. The lower end of the slider is fixed with a fixed frame. This tempered glass processing drilling device, designed to prevent breakage, utilizes multiple components working together to not only prevent tempered glass from shattering during processing and endangering workers' health, but also facilitates adjustment of the drilling position while preventing breakage, improving the equipment's versatility. Furthermore, it has the ability to fix the tempered glass in place, ensuring a secure position and thus enhancing drilling accuracy. The existing drilling devices still have the following problems in actual use: 1. During drilling, the friction between the drill bit and the glass generates a large amount of heat. The sudden increase in local temperature can easily cause the glass to crack due to thermal stress. Existing technologies mostly use external spraying or manual pouring of coolant, which has problems such as uneven cooling, serious waste of water resources, and environmental pollution and difficulty in recycling when coolant mixes with glass fragments. 2. Drilling feed pressure often relies on manual adjustment by workers' experience or simple mechanical control, making precise quantification impossible. Excessive pressure can directly crush the glass, especially when the drill is about to penetrate; insufficient pressure can lead to slippage, low efficiency, or failure to form a hole. This uncertainty affects the consistency of processing quality and yield. 3. Drilling produces tiny glass shards that fly everywhere, making cleanup tedious and posing safety hazards. The entire process often requires multiple manual interventions, from positioning and drilling to cleaning, resulting in low levels of automation and integration, which impacts production efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a drilling device for special glass processing to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a drilling device for special glass processing, comprising a steel frame, a base, a water tank, and a support. The base is disposed below the steel frame, and the water tank and support are fixed on the base. A lifting mechanism is installed on the water tank, and a cooling mechanism is installed on the support. A mounting box is fixed on the support, and a second cylinder is fixed inside the mounting box. A movable box is fixed to the output end of the second cylinder, and an adjusting mechanism is installed inside the movable box. The adjusting mechanism includes a mounting plate disposed inside the movable box, and a mounting plate with a fixed upper side. A buffer pad is provided. A motor is fixed to the underside of the mounting plate. A rotating shaft is fixed to the output end of the motor. A lever is connected to a bearing on the rotating shaft, and a torsion spring connects the lever to the rotating shaft. A limit rod for limiting the unidirectional rotation of the lever is also fixed on the rotating shaft. A drilling mechanism is installed at the lower end of the rotating shaft. The mounting plate and the threaded rod connected to the bearing on the movable box are threaded together. A spiral spring connects the threaded rod to the movable box. A disc is fixed to the lower end of the threaded rod. Vertical rods are fixed at equal angles on the disc, and the vertical rods are slidably connected to the lever.

[0005] Preferably, the upper surface of the steel frame is evenly equipped with casters for glass movement, and a collection box is provided on the lower side of the steel frame. The rolling action of the casters can facilitate the movement of the glass, thereby providing a basic guarantee for the drilling of the glass.

[0006] Preferably, the lifting mechanism includes a first cylinder fixed on the water tank, and a support platform is fixed to the output end of the first cylinder. Rubber strips are evenly fixed on the support platform, and a movable sleeve that is slidably connected to the water tank is fixed to the lower end of the support platform. Through the action of the first cylinder, the position of the support platform can be adjusted. Combined with the friction between the rubber strips and the glass, the glass can be positioned to prevent the glass from sliding.

[0007] Preferably, a filter plate is fixed obliquely on the movable sleeve, and the end of the filter plate is located above the collection box. Through the action of the filter plate, the glass fragments can be separated from the cooling water, so as to realize the recycling of the cooling water.

[0008] Preferably, the cooling mechanism includes a water pump fixed on a water tank, and the water pump is connected to a water guide rod through a conduit. The water guide rod is connected to a water distribution ring to deliver water. Meanwhile, nozzles are evenly installed on the inner side of the water distribution ring, and the central axis of the nozzles coincides with the central axis of the drill. Through the above structure, a cooling effect can be achieved when drilling glass, which can reduce the wear of the drill and prevent the glass from cracking due to high temperature.

[0009] Preferably, a rubber pad is fixed to the lower end of the water distribution ring, and the lower end surface of the rubber pad is higher than the upper end surface of the caster wheel. Through the action of the rubber pad, the overflow of cooling water can be effectively prevented, so as to ensure the normal recycling of cooling water.

[0010] Preferably, a self-locking mechanism is fixed on the threaded rod. The self-locking mechanism includes a ratchet fixed to the upper end of the threaded rod, and the ratchet engages with a pawl. The pawl is rotatably connected to a crossbar, and a torsion spring is fixed between the crossbar and the pawl. Through the engagement of the ratchet and the pawl, the unidirectional rotation of the threaded rod can be limited.

[0011] Preferably, the crossbar and the fixed plate are slidably connected, and the fixed plate is fixed on the movable box. A first spring is fixed between the crossbar and the fixed plate, and a first magnet is also fixed on the crossbar. The first magnet and the second magnet form a magnetic attraction, and the second magnet is fixed on the second cylinder. Through the magnetic attraction between the first magnet and the second magnet, the ratchet and the pawl can be separated to ensure the normal operation of the device. Combined with the elasticity of the first spring, it can provide a basic force for the automatic reset of the pawl.

[0012] Preferably, the drilling mechanism includes a cylinder fixed to the lower end of the rotating shaft, and a slide rod is slidably connected to the cylinder. A detachable drill is installed at the lower end of the slide rod. The normal drilling of the glass can be ensured by the action of the drill.

[0013] Preferably, one end of the slide rod is fixed to one end of the second spring, and the other end of the second spring is fixed to the pressure sensor. The pressure sensor is fixed inside the cylinder. Through the action of the pressure sensor, the pressure generated by the initial punch on the glass can be detected, thereby effectively preventing the glass from breaking due to excessive pressure.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This special glass processing drilling device achieves initial friction positioning by driving the support platform and rubber strip upward with the first cylinder. The continued upward movement presses the glass tightly against the rubber pad at the lower end of the cooling ring, forming a secondary positioning. This not only ensures that the glass is securely fixed and prevents displacement during processing, but also creates a local sealed area for the cooling water, improving cooling efficiency and preventing water overflow. 2. This special glass processing drilling device, through the combination of spring and pressure sensor installed in the drilling mechanism, can detect the pressure applied by the drill bit to the glass in real time and accurately. It can also be linked with the second cylinder through the control system (not shown in the figure, such as PLC) to ensure that the pressure is always within the preset safety window (such as 0.18MPa~0.30MPa), which fundamentally avoids glass breakage caused by uncontrolled pressure. It is particularly suitable for the precision processing of thin glass or irregularly shaped glass. 3. This special glass processing drilling device, through an adjustment mechanism consisting of a motor-driven lever, vertical rod, and threaded rod, converts rotary motion into precise, intermittent, minute linear downward movement (0.2mm-0.5mm each time). This intermittent feed progressive drilling method, compared with traditional continuous feed, effectively reduces the single cutting force, lowers the instantaneous stress of the glass, makes the drilling process smoother, the hole wall smoother, and significantly improves drilling quality and accuracy. 4. This special glass processing drilling device features a self-locking mechanism that reliably locks the threaded rod during drilling via ratchet and pawl, preventing it from retracting under spring pressure. This ensures the stability and cumulative accuracy of each micro-feed. After drilling is completed, the cylinder retracts and automatically releases the self-locking mechanism via magnetic attraction. Under the action of the spiral spring, the drill bit assembly is driven to quickly reset. The entire process requires no manual intervention, exhibiting a high degree of automation and intelligence, thus improving the continuity and efficiency of operations. 5. This special glass processing drilling device features a cooling mechanism that uses ring-shaped nozzles to precisely and evenly spray cooling water onto the contact point between the drill bit and the glass. This results in high cooling efficiency and concentrated water usage. An inclined filter plate filters the cooling water and returns it to the water tank for reuse, while glass fragments are separated and collected in a collection box. This achieves the recycling of cooling water, conserves water resources, maintains a clean working environment, and meets the requirements of green production. Attached Figure Description

[0017] 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.

[0018] Please see Figures 1-7This invention provides a technical solution: a drilling device for special glass processing, comprising a steel frame 1, a base 2, a water tank 3, and a support 5. The base 2 is disposed below the steel frame 1, and the water tank 3 and support 5 are fixed on the base 2. A lifting mechanism 4 is installed on the water tank 3, and a cooling mechanism 6 is installed on the support 5. A mounting box 7 is fixed on the support 5, and a second cylinder 8 is fixed inside the mounting box 7. A movable box 9 is fixed to the output end of the second cylinder 8, and an adjusting mechanism 10 is installed inside the movable box 9. The adjusting mechanism 10 includes a mounting plate 1001 disposed inside the movable box 9, a buffer pad 1002 fixed to the upper side of the mounting plate 1001, and a motor 1003 fixed to the lower side of the mounting plate 1001. The output end of the motor 1003... A rotating shaft 1004 is fixed, and a lever 1005 is connected to the rotating shaft 1004 by a bearing. A torsion spring is connected between the lever 1005 and the rotating shaft 1004. A limiting rod 1006 is also fixed on the rotating shaft 1004 to limit the unidirectional rotation of the lever 1005. A drilling mechanism 12 is installed at the lower end of the rotating shaft 1004. The mounting plate 1001 is threadedly connected to the threaded rod 1007 on the movable box 9. A spiral spring 1008 is connected between the threaded rod 1007 and the movable box 9. A disc 1009 is fixed at the lower end of the threaded rod 1007. A vertical rod 1010 is fixed at equal angles on the disc 1009. The vertical rod 1010 is slidably connected to the lever 1005.

[0019] The upper surface of the steel frame 1 is evenly equipped with casters 101 for glass movement, and a collection box 102 is provided on the lower side of the steel frame 1; the lifting mechanism 4 includes a first cylinder 401 fixed to the water tank 3, and a support platform 402 is fixed to the output end of the first cylinder 401, and rubber strips 403 are evenly fixed on the support platform 402, while a movable sleeve 404 that is slidably connected to the water tank 3 is fixed to the lower end of the support platform 402; a filter plate 405 is obliquely fixed on the movable sleeve 404, and the end of the filter plate 405 is... Located above the collection box 102; the cooling mechanism 6 includes a water pump 601 fixed on the water tank 3, and the water pump 601 is connected to the water guide rod 602 through a conduit, and the water guide rod 602 is connected to the water distribution ring 603 to deliver water. At the same time, nozzles 604 are evenly installed on the inner side of the water distribution ring 603, and the central axis of the nozzles 604 coincides with the central axis of the punch 1205; a rubber pad 605 is fixed at the lower end of the water distribution ring 603, and the lower end surface of the rubber pad 605 is higher than the upper end surface of the universal wheel 101. When using this special glass processing drilling device, such as Figures 1-7As shown, the glass to be drilled is first placed on the caster 101. At this time, the first cylinder 401 is in the retracted state, so that the rubber strip 403 is not in contact with the glass. Through the rolling action between the caster 101 and the glass, the position of the glass can be easily adjusted to determine the drilling position. After the glass position is adjusted, the first cylinder 401 is activated, thereby driving the support 402 and the rubber strip 403 to move upward. When the rubber strip 403 contacts the glass, the friction between the rubber strip 403 and the glass can achieve a single-stage positioning of the glass. At this point, the first cylinder 401 continues to extend, thereby driving the support platform 402, rubber strip 403 and glass to continue to move upward until the upper surface of the glass contacts and seals with the rubber pad 605. This can achieve secondary positioning of the glass and ensure stability in subsequent glass processing. After the glass is fixed, the water pump 601 starts to send the cooling water in the water tank 3 into the water guide rod 602. The cooling water enters the water distribution ring 603 through the water guide rod 602 and is sprayed out through the nozzle 604, which can cool the glass drilling and prevent the glass from breaking due to excessive temperature. The punching mechanism 12 includes a cylinder 1201 fixed to the lower end of the rotating shaft 1004, and a slide rod 1202 slidably connected to the cylinder 1201. A detachable punch 1205 is installed at the lower end of the slide rod 1202. The slide rod 1202 is fixed to one end of a second spring 1203, and the other end of the second spring 1203 is fixed to a pressure sensor 1204. The pressure sensor 1204 is fixed inside the cylinder 1201. After the glass is fixed, as follows Figures 1-7As shown, at this time, the second cylinder 8 extends, causing the movable box 9, adjusting mechanism 10, self-locking mechanism 11, and drilling mechanism 12 to move downwards. When the drill 1205 contacts the upper end of the glass, the drill 1205 is limited. At this time, the second cylinder 8 continues to extend, causing the drill 1205 to move relative to the cylinder 1201 under force, thereby causing the second spring 1203 to contract under force. With the help of the pressure sensor 1204, the pressure generated by the drill 1205 on the glass can be detected (taking 5mm thick glass as an example, its drilling pressure is 0.18MPa~0.30MPa), avoiding the problem of the glass breaking due to excessive pressure from the drill 1205. After the adjustment is completed, the second cylinder 8 stops extending, and the motor 1003 drives the rotating shaft 1004, cylinder 1201, slide rod 1202, and drill 1205 to rotate clockwise. The rotating shaft 1004 rotates clockwise, simultaneously driving the lever 1005 to rotate. When the lever 1005 contacts and slides with the vertical rod 1010, the limiting rod 1006 prevents the lever 1005 from swinging, causing the disc 1009 and threaded rod 1007 to rotate under force. Combined with the threaded connection between the threaded rod 1007 and the mounting plate 1001, the mounting plate 1001, rotating shaft 1004, cylinder 1201, and drill 1205 are forced to move downward by 0.2mm-0.5mm. When the lever 1005 separates from the vertical rod 1010, the mounting plate 1001, rotating shaft 1004, and cylinder 1201 remain stationary. Based on the above principle, the mounting plate 1001 can be moved downward intermittently, allowing the drill 1205 to perform a progressive drilling action on the glass. A self-locking mechanism 11 is fixed on the threaded rod 1007. The self-locking mechanism 11 includes a ratchet 1101 fixed on the upper end of the threaded rod 1007, and the ratchet 1101 cooperates with the pawl 1102. The pawl 1102 is rotatably connected to the crossbar 1103. At the same time, a torsion spring is fixed between the crossbar 1103 and the pawl 1102. The crossbar 1103 is slidably connected to the fixed plate 1104. The fixed plate 1104 is fixed on the movable box 9. A first spring 1105 is fixed between the crossbar 1103 and the fixed plate 1104. At the same time, a first magnet 1106 is also fixed on the crossbar 1103. The first magnet 1106 and the second magnet 1107 form a magnetic attraction result. The second magnet 1107 is fixed on the second cylinder 8. When the second cylinder 8 extends, as Figures 1-7As shown, at this time, the moving box 9 moves down, causing the ratchet 1101, pawl 1102, and first magnet 1106 to move down. When the first magnet 1106 separates from the second magnet 1107, the pawl 1102 moves towards the ratchet 1101 under the elastic action of the first spring 1105, until the ratchet 1101 and pawl 1102 engage with each other. During the processing, when the lever 1005 contacts and slides with the vertical rod 1010, causing the threaded rod 1007 to rotate, the ratchet 1101 is simultaneously rotated. When the lever 1005 separates from the vertical rod 1010, the pawl 1102 limits the ratchet 1101, preventing the threaded rod 1007 from resetting due to the elastic reversal of the spiral spring 1008. This provides a basic guarantee for the intermittent and stable downward movement of the mounting plate 1001, thus enabling the glass to... Progressive drilling provides a basic guarantee. After drilling is completed, the device can be reset by retracting the second cylinder 8. During the process of the second cylinder 8 retracting and moving the movable box 9 upward, when the first magnet 1106 and the second magnet 1107 are attracted and fixed, the first spring 1105 is compressed, causing the pawl 1102 to separate from the ratchet 1101, thereby releasing the limiting effect of the threaded rod 1007. The threaded rod 1007 is then reversed and reset under the elastic action of the spiral spring 1008, thereby automatically resetting the mounting plate 1001, the rotating shaft 1004, and the cylinder 1201 for the next processing. After the glass drilling is completed, the glass fragments fall onto the filter plate 405 and are collected in the collection box 102 by the guiding action of the inclined filter plate 405. This is the working principle of the drilling device for special glass processing.
