Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, and in particular to a tooling for positioning glass drilling holes. Background Technology

[0002] Glass drilling is a technique that uses specialized equipment and processes to create holes of a specific diameter on the surface of glass. During the drilling process, diamond drill bits are used in conjunction with water cooling to drill holes that meet the required precision on the glass panel while avoiding glass breakage and chipping. Because glass is brittle and hard, it is very easy to cause positional deviations or even breakage during drilling, making glass drilling positioning fixtures a key component of the drilling process.

[0003] Glass drilling positioning fixtures can accurately determine the drilling position. Through a precisely designed laser-assisted positioning, clamping mechanism and guiding device, the glass is accurately fixed in the preset drilling position, effectively solving the problems of brittle and easily damaged glass material and high drilling accuracy requirements, and significantly improving drilling efficiency and processing quality.

[0004] Although the glass drilling positioning fixture can ensure the stability of the drilling process, the positioning fixture in the device is designed for glass of specific size and shape. When processing glass of different specifications, it cannot be accurately adapted, and the fixture needs to be redesigned or replaced, which increases production costs and production preparation time. The existing solution is to design movable positioning blocks or telescopic clamps. By adjusting the position and size of the positioning blocks or clamps, the processing needs of glass of different sizes and shapes can be adapted. However, adjustable fixtures will introduce new errors during the adjustment process, and their adjustment range is also limited. They still cannot be well adapted to glass of special specifications or complex shapes. Utility Model Content

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by starting the hydraulic pump, the piston of the hydraulic cylinder moves down, causing the fixing plate to move down synchronously. Then, the electric push rod is started so that the vacuum suction cup can be pressed tightly against the glass.

When the balancer detects an abnormality, the position of the inertial mass block is adjusted by starting the motor, thereby adjusting the center of gravity of the damping base. This effectively improves the accuracy of glass positioning and processing stability, reduces the risk of glass breakage, and improves processing efficiency. Attached Figure Description

[0032] 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.

[0033] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a glass drilling positioning fixture, including a base plate 1 and a top plate 2. A processing groove 4 is formed on the top of the base plate 1, serving as the drilling position for the glass. A hydraulic cylinder 5 is fixedly connected to the top of the top plate 2, enabling the drilling machine to move up and down. A fixing plate 6 is fixedly connected to the bottom of the hydraulic cylinder 5, providing space for the drilling machine and electric push rods 7. Two electric push rods 7 are fixedly connected to the bottom of the fixing plate 6, enabling the vacuum suction cup 10 to move up and down. Both electric push rods 7 are fixedly connected to universal joints 8 at their bottom ends. Universal joints 8 facilitate the vacuum suction cup 10 to adapt to irregularly shaped glass. Fixed cylinders 9 are fixedly connected to the bottom ends of both universal joints 8, protecting the electric one-way valves 14. Vacuum suction cups 10 are fixedly connected to the bottom ends of both fixed cylinders 9, allowing the vacuum suction cups 10 to adsorb and fix the glass. Two electric one-way valves 14 are fixedly connected to the top of the outer walls of both vacuum suction cups 10, allowing the air between the vacuum suction cups 10 and the glass to be... For extraction and insertion, air supply pipes 15 are connected to the left and right adjacent sides of the two fixed cylinders 9, allowing air to enter between the vacuum suction cup 10 and the glass. An oil supply assembly is installed at the top of the top plate 2, a gear transmission assembly is installed on the inner wall of the processing groove 4, and an air extraction assembly is installed at the top of the top plate 2. A stabilizing mechanism 3 is installed on the inner wall of the processing groove 4 to maintain stable positioning during glass drilling. The oil supply assembly includes an oil tank 16 for storing hydraulic oil, and the bottom of the oil tank 16 is fixedly connected to the top left side of the top plate 2. A hydraulic pump 17 is fixedly connected to the rear top of the top plate 2. The hydraulic pump 17 sends the hydraulic oil in the oil tank 16 into the hydraulic cylinder 5. The air extraction assembly includes an air storage tank 11, which is used to store air. The bottom of the air storage tank 11 is fixedly connected to the top right side of the top plate 2. An air pump 12 is fixedly connected to the top right side of the top plate 2. The air pump 12 extracts the air between the vacuum suction cup 10 and the glass. The left end of the air pump 12 is connected to a vacuum hose 13, which guides the extracted air so that the extracted air is stored in the air storage tank 11.

[0034] Specifically, the glass to be drilled is placed in the processing groove 4 of the base plate 1. The hydraulic pump 17 is started, allowing hydraulic oil to enter the hydraulic cylinder 5 from the oil tank 16 through the pipe, pushing the piston of the hydraulic cylinder 5 downward. The fixing plate 6 also moves downward. The electric push rod 7 is started, making the vacuum suction cup 10 fit tightly against the glass surface. The air pump 12 is turned on, and the air between the vacuum suction cup 10 and the glass is extracted through the vacuum hose 13. The two electric one-way valves 14 ensure that the air flows in one direction. As the air is extracted, a vacuum is formed between the vacuum suction cup 10 and the glass, adsorbing the glass onto the vacuum suction cup 10, thus achieving the initial fixation of the glass. After drilling is completed, the drilling machine is turned off, and the air pump 12 is turned off. The electric one-way valve 14 is opened, allowing air to enter between the vacuum suction cup 10 and the glass, so that the vacuum suction cup 10 is detached from the glass. Then, the electric push rod 7 is shortened, causing the vacuum suction cup 10 to completely separate from the glass. The hydraulic pump 17 is started, causing the piston of the hydraulic cylinder 5 to rise, causing the fixing plate 6 to rise and detach from the glass surface.

[0035] Reference Figure 2 , Figure 5 and Figure 6 The stabilizing mechanism 3 includes a damping base 301. The outer wall of the damping base 301 is slidably connected to the inner wall of the processing groove 4. Multiple support columns 302 are fixedly connected to the top of the damping base 301. These support columns 302 support the glass plate, and each support column 302 has a silicone anti-slip pad 303 fixedly connected to its top. The silicone anti-slip pad 303 increases friction and reduces vibration to a certain extent. Ball screws 304 are rotatably connected to the front and rear sides of the inner wall of the damping base 301. The ball screws 304 guide the movement of the inertial mass block 305. The outer walls of both ball screws 304 are threadedly connected to the inertial mass block 305. 05 Adjust the balance of the damping base 301. A balancer 306 is fixedly connected to the bottom right side of the damping base 301. The balancer 306 can detect the balance of the damping base 301. The gear transmission assembly includes two motors 307. The two motors 307 provide power for the movement of the inertial mass block 305. The tops of the two motors 307 are fixedly connected to the top of the inner wall of the damping base 301. The output ends of the two motors 307 are fixedly connected to gear 1 308. The outer right ends of the two ball screws 304 are fixedly connected to gear 2 309. Gear 1 308 and gear 2 309 are used to transmit the power of the motors 307 to the ball screws 304.

[0036] Specifically, the glass to be drilled is placed in the processing groove 4 of the base plate 1, so that the silicone anti-slip pad 303 initially contacts the bottom of the glass, providing a certain friction to prevent the glass from sliding over a large area. The balancer 306 monitors the balance of the damping base 301 in real time, and then the glass is positioned by the vacuum suction cup 10. Before starting the drilling machine, the two motors 307 start working. The gear 1 308 at the output end of the motor 307 meshes with the gear 2 309 on the ball screw 304, driving the ball screw 304 to rotate, so that the ball screw 304 rotates. 04 The threaded inertial mass block 305 moves axially along the lead screw. The balancer 306 continuously monitors the balance of the damping base 301. The drilling machine is started to drill the glass. During the drilling process, based on the detection results of the balancer 306, the movement distance and direction of the inertial mass block 305 are precisely controlled by adjusting the speed and direction of the motor 307, so that the damping base 301 maintains dynamic balance. The support column 302 and the silicone anti-slip pad 303 provide stable support for the glass, reducing the impact of vibration on drilling accuracy and glass integrity.

[0037] Reference Figure 1 , Figure 2 and Figure 3 Two telescopic guide rods 19 are fixedly connected to the top of the fixed plate 6. The two telescopic guide rods 19 provide guidance for the drilling device. Limiting blocks 20 are fixedly connected to the top of each of the two telescopic guide rods 19. The limiting blocks 20 are used to limit the movement of the telescopic guide rods 19. Two guide grooves 311 are opened on the top of the inner wall of the damping base 301. Guide posts 310 are fixedly connected to the top of each of the two inertial mass blocks 305. Through the sliding connection between the two guide grooves 311 and the guide posts 310, the movement of the inertial mass blocks 305 can be more precise and smooth. Two ventilation grooves 18 are opened on the outer wall of each of the two fixed cylinders 9. The internal dimensions of the multiple ventilation grooves 18 are all in line with the external dimensions of the vacuum hose 13 and the two gas delivery pipes 15. The multiple ventilation grooves 18 are used to allow the vacuum hose 13 and the gas delivery pipes 15 to pass through the fixed cylinders 9.

[0038] Specifically, when the hydraulic pump 17 causes the hydraulic cylinder 5 to push the fixed plate 6 downward, the telescopic guide rod 19 at the top of the fixed plate 6 extends synchronously, providing guidance for the vertical movement of the drilling device, ensuring that the drilling device moves smoothly downward along a straight line, and avoiding deviation that affects drilling accuracy. The limiting block 20 at the top of the telescopic guide rod 19 can prevent the telescopic guide rod 19 from moving excessively, preventing the drilling device from exceeding its safe stroke. When the motor 307 drives the gear 308, gear 309 and ball screw 304 to rotate, the inertial mass block 305 moves axially. The guide post 310 at the top slides in the guide groove 311 at the top of the inner wall of the damping base 301, reducing the shaking and friction of the inertial mass block 305 during movement, thereby adjusting the center of gravity of the damping base 301 more efficiently and maintaining the balance of the device. When the air pump 12 uses the vacuum hose 13 to draw air from the vacuum suction cup 10 and introduces air through the air supply pipe 15, the ventilation groove 18 provides a fixed and smooth channel for the vacuum hose 13 and the air supply pipe 15, preventing the pipe from loosening and affecting the vacuum adsorption and release effect, and ensuring the stable transmission of air in the pipe.

[0039] Working principle: The glass to be drilled is placed in the processing groove 4 of the base plate 1, so that the glass has a stable initial position during the drilling process. The hydraulic pump 17 is started, and hydraulic oil enters the hydraulic cylinder 5 from the oil tank 16 through the pipeline, pushing the piston of the hydraulic cylinder 5 to move downward. Since the piston of the hydraulic cylinder 5 is connected to the fixed plate 6, the fixed plate 6 moves downward with the movement of the piston. When the fixed plate 6 moves downward to a certain position, the electric push rod 7 is started, so that the vacuum suction cup 10 is tightly attached to the glass surface, which increases the adaptability of the tooling to glass of different shapes and sizes. The air pump 12 is turned on, and the air pump 12 connects the vacuum suction cup 10 to the glass through the vacuum hose 13. The air between the vacuum cups is extracted, and the two electric one-way valves 14 ensure that the air flows in one direction. As the air is extracted, a vacuum is formed between the vacuum cup 10 and the glass. Atmospheric pressure is used to adsorb the glass onto the vacuum cup 10, achieving the initial fixation of the glass. Then, the drilling machine is started to drill holes in the glass. After the drilling is completed, the drilling machine is turned off, the air pump 12 is turned off, and the electric one-way valve 14 is opened to allow air to enter between the vacuum cup 10 and the glass, so that the vacuum cup 10 is detached from the glass. Next, the electric push rod 7 is started to drive the vacuum cup 10 to completely separate from the glass. Finally, the hydraulic pump 17 is started to detach the fixing plate 6 from the glass surface.

[0040] Furthermore, when the glass is placed in the processing tank 4, the silicone anti-slip pad 303 contacts the bottom of the glass due to surface friction, limiting the glass's large-scale horizontal sliding through friction and achieving pre-positioning. Simultaneously, the balancer 306 monitors the balance state of the damping base 301 in real time. After the vacuum suction cup 10 fixes the glass, the motor 307 drives the gear 1 308 to rotate, transmitting power to the ball screw 304 through the gear 2 309, causing the ball screw 304 to rotate. At the same time, the inertial mass block 305 moves axially. By changing the distribution of the mass block, the center of gravity position of the damping base 301 is actively adjusted, achieving initial balance calibration. During drilling, the glass vibrates due to the cutting force of the drill bit, causing the damping base 301 to become unbalanced. When the vibration on one side intensifies, the motor 307 rotates the ball screw 304, causing the inertial mass block 305 to move in the corresponding direction, adjusting the center of gravity position of the damping base 301, counteracting the vibration energy, and maintaining the balance of the base.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
