Description

Technical Field

[0001] This utility model relates to the field of deep hole drilling, and in particular to a portable, self-guided, clean BTA deep hole drilling equipment. Background Technology

[0002] Deep hole drilling presents numerous challenges that severely restrict its development and application. First, the depth-to-diameter ratio of the drilled hole is typically greater than five, resulting in excessively large cantilever arms on the tool holder and extremely weak tool rigidity. This makes the hole prone to deviation during machining, making it difficult to guarantee machining accuracy. Second, during deep hole drilling, the tool is in a semi-enclosed state inside the deep hole, making it difficult for the cutting fluid to reach the cutting zone smoothly. This leads to poor tool heat dissipation and accelerated wear, increasing tool costs and affecting machining efficiency and quality. Furthermore, the chips generated during deep hole drilling are difficult to remove from the tool's chip flutes. Increased friction between the chips and the hole wall can clog the chip flutes, further increasing drilling torque and reducing machining efficiency and quality.

[0003] Existing deep hole machining technologies each have their advantages and disadvantages. Gun drills, due to the presence of chip grooves in the V-shaped tool holder, have weak rigidity, making it impossible to use large feed rates and resulting in low drilling efficiency. Jet-suction drills use a double-tube chip removal system, which leads to a complex tool and tool holder structure, reduced tool strength and chip removal cross-section, and a greater tendency to cause chip clogging when machining small holes. Although the DF system improves chip removal efficiency by adding a negative pressure chip extractor, it has poor versatility for various hole diameters. BTA drills, which have become the mainstream deep hole machining technology, use a single-layer circular tube as the tool holder, which has good rigidity and a large chip removal cross-section. High-pressure cutting fluid is used to remove chips from the annular gap between the hole wall and the drill rod to the cutting zone. Furthermore, the tool uses a combination of tooth cutting and guide bar pressing to achieve a balance between tangential and radial forces during drilling, ensuring the tool's self-centering and self-guiding.

[0004] However, BTA deep hole drilling equipment has obvious shortcomings. It is a special-purpose machine tool, and due to the requirements of hole depth processing, the machine bed is large and expensive, which increases the procurement and operating costs of enterprises. In addition, the drilling process requires the use of oily cutting fluid containing sulfur and phosphorus extreme pressure additives, which seriously pollutes the processing environment and endangers the health of operators.

[0005] Therefore, it is necessary to provide a portable, clean, self-guided BTA deep hole drilling equipment to solve the above-mentioned technical problems. Utility Model Content

[0025] Intelligent operation lowers the barrier to entry: The integrated control system, combined with a PLC control module and a touch screen interface, supports one-click parameter setting, simplifies the operation process, and allows non-professionals to get started quickly, reducing training costs and time, improving equipment applicability and production efficiency, and making it suitable for enterprises of different sizes and diverse processing needs.

[0026] Highly adaptable and covering a variety of processing needs: It can precisely control parameters such as feed rate and rotation speed according to material characteristics and processing depth. It is suitable for deep hole processing of complex materials such as high-strength alloys and titanium alloys, as well as conventional materials such as carbon steel and stainless steel. With its portability, it can quickly respond to processing needs in scenarios such as on-site maintenance and customized small-batch production, thereby improving production efficiency and flexibility.

[0027] Cost reduction and efficiency improvement, and optimization of cost structure: Convenience enables equipment to be put into production quickly and reduces downtime; Precision and efficiency improve production efficiency; Vortex tube chip removal device eliminates the need for cutting fluid, reducing the cost of cutting fluid procurement, storage and disposal, and optimizing the production cost structure.

[0028] Safe and reliable, reducing operational risks: Reduces the use of cutting fluid, avoiding safety accidents such as slips and fires caused by cutting fluid leakage or evaporation.

[0047] A control panel 26 is mounted on the surface of the outer casing 27.

[0048] The first helical gear 9 and the second helical gear 10 are provided with gear protective covers 19.

[0049] The top of the outer casing 27 is connected to a first handle 25 and a second handle 28 on both sides.

[0050] The worktable base 5 is the supporting foundation of the entire drilling platform. The slide table 3 moves forward and backward precisely on the guide rail of the base. The slide table 3 is connected to the spindle screw 4. The feed motor 1 drives the right side of the spindle screw 4. The top of the slide table 3 is connected to the motor support frame 12 by hexagonal bolts. The top of the motor support frame 12 is connected to the spindle motor 11 by hexagonal bolts. The first helical gear 9 and the drill rod clamp 20 are fixed at the left and right ends of the motor support frame, respectively. The second helical gear 10 is fixed to the left side of the spindle motor 11 by a key. The first helical gear 9 and the second helical gear 10 drive the drill rod clamp 20 to rotate through gear transmission. The drill rod 13 is clamped at the right end of the drill rod clamp 20. The drill rod 13 passes through the gas storage box 15 and connects to the staggered tooth BTA drill bit 18.

[0051] The high-pressure cold air supply device includes a vortex tube 16, a gas storage box 15, an air inlet pipe 21, and an exhaust pipe 22. The gas storage box 15 has a first sealing ring 14 and a second sealing ring 17 fixed in the through holes on the left and right sides. The cold air inlet 23 of the vortex tube 16 is fixed at the interface on the top of the gas storage box 15. The air inlet pipe 21 is connected to an external air pump, and the exhaust pipe 22 is connected to a hose to discharge high-temperature gas.

[0052] The workpiece clamping device mainly consists of an electromagnetic chuck 24, which is fixed on a gas storage box 15. The electromagnetic chuck 24 and the gas storage box 15 are fixed to the platform of the right support plate 6 by hexagonal bolts.

[0053] The worktable base 5 is the core support component of the entire equipment, providing a stable foundation for the drilling platform. The base design takes into account both structural robustness and the platform's portability, making it suitable for portable operation. The slide 2 is mounted on the base via precise guide rails, enabling precise forward and backward movements to ensure stability and high precision during the drilling process. The slide 3, in conjunction with the spindle screw 4, forms the main feed system of the platform. The spindle screw 4 is driven by the feed motor 1, which is mounted on the left side of the spindle screw 4. Through precise control, the feed system operates efficiently.

[0054] To ensure the structural stability and efficient power transmission of the drilling equipment, the top of the slide table 6 is connected to the motor support frame 12 via hexagon socket bolts. The top of the motor support frame 12 is connected to the spindle motor 11 via hexagon socket bolts. The spindle motor 11 has the advantages of high efficiency, stability, and low noise, and can provide reliable power support. The left and right ends of the motor support frame 12 are respectively fixed with the first helical gear 9 and the drill rod clamp 20. Through the connection of these components, the power of the motor can be effectively transmitted to the drill rod clamp 20, causing it to rotate under the action of gear transmission. The left side of the spindle motor 11 is fixed with the second helical gear 10 via a key connection. These two helical gears drive the drill rod clamp 20 together through the gear transmission system, ensuring the precise rotation of the drill rod clamp.

[0055] The drill rod 13 is firmly clamped at the right end of the drill rod chuck 20. The drill rod 13 passes through the gas storage box 15 and is finally connected to the staggered tooth BTA drill bit 18. The staggered tooth BTA drill bit and the drill rod are connected by a rectangular thread, which significantly improves the replacement efficiency. Compared with the single tooth BTA drill bit, the staggered tooth BTA drill bit adopts a multi-tooth staggered distribution design, which effectively controls the width of the chips during the cutting process and achieves a good chip breaking effect. At the same time, the rake face of each tooth is also equipped with a chip breaking platform structure, which assists chip breaking by increasing the bending deformation of the chips. This design not only optimizes the chip breaking and chip breaking capabilities, but also greatly improves the chip removal efficiency of BTA deep hole drilling, providing higher stability and machining quality for deep hole machining.

[0056] To effectively remove chips during the drilling process and keep the equipment clean, the high-pressure cold air supply device plays a crucial role as an important component of the equipment. The vortex tube 16 and the gas storage box 15 together constitute this device. The first sealing ring 14 and the second sealing ring 17 are fixed to the through holes on the left and right sides of the gas storage box 15, respectively, to ensure the airflow sealing and the high efficiency of the chip removal process. The cold air outlet 23 of the vortex tube 16 is fixed at the interface on the top of the gas storage box 15. The high-pressure cold air flow can effectively reduce the temperature of the drilling area and reduce the thermal expansion caused by high temperature. At the same time, the high-pressure gas is used to remove chips. The air inlet pipe 21 is connected to an external air pump to provide the required compressed gas, and the exhaust pipe 22 is connected to a hose to discharge the high-temperature gas, ensuring effective control of the drilling area temperature and smooth chip removal.

[0057] For workpiece fixation, the equipment uses an electromagnetic chuck 24 as the main clamping device. The electromagnetic chuck 24 is fixed to the right support plate 6 of the platform by an internal hex bolt and a gas storage box 15. The suction force can be adjusted as needed to achieve rapid and firm adsorption of the workpiece. Considering the different shapes of the workpieces being processed, the workpiece clamping device of this utility model can also install common clamps such as three-jaw chucks and bench vises on the electromagnetic chuck 24. The electromagnetic chuck 24 can adjust the suction force according to the size and shape of the workpiece to ensure that the workpiece remains stable during drilling and avoids affecting the drilling accuracy due to workpiece loosening.

[0058] like Figure 5As shown, the high-pressure cold air supply device consists of a vortex tube and a gas storage tank. The vortex tube is a simple yet efficient energy separation device, mainly composed of a nozzle, a vortex chamber, a separation orifice plate, and pipes at both the hot and cold ends. Its working principle is that compressed and cooled gas enters the nozzle, expands and accelerates to the speed of sound in the nozzle, and is injected into the vortex chamber tangentially, forming a free vortex. The rotational angular velocity of the free vortex is greater closer to the center. Due to the difference in angular velocity, friction is generated between the layers of the free vortex. The airflow in the central part has the largest angular velocity. The result of friction is that energy is transferred to the outer layer of airflow with a lower angular velocity. The airflow in the central layer loses energy, has low kinetic energy, and its speed and temperature decrease. It is drawn out from one end through the orifice plate in the center of the vortex tube to obtain the cold airflow required for cooling. The airflow in the outer layer gains momentum and its kinetic energy increases. At the same time, it rubs against the turbine tube wall, converting some of the kinetic energy into heat energy, which is drawn out from the other end of the vortex tube through a control valve to form a hot airflow.

[0059] In practical applications, the distribution of hot and cold airflow can be optimized by adjusting the fluid ratio within the pipe, thereby achieving the best cooling or heating effect. High-pressure gas first expands and accelerates through the nozzle, then enters the vortex chamber and rotates at extremely high speeds, reaching 1.0 × 10⁻⁶. 6 In RPM (Rotating Perm Gas) vortex tubes, high-speed airflow rotates along the tube wall, causing friction with the wall and a rapid increase in gas temperature. This hot airflow is discharged from the hot end of the tube, where its temperature is higher than that of the original compressed gas. Simultaneously, some gas flows back along the centerline of the tube, forming a recirculating airflow. This recirculating airflow interacts with the vortex of the outer airflow, continuously exchanging heat and causing the airflow temperature to gradually decrease, eventually forming a cold airflow, which is then discharged from the cold end of the tube. This process is known as the "vortex effect".
