Description

Technical Field

[0001] The present invention relates to the field of deep hole drilling, and in particular to a portable self-guided BTA deep hole drilling equipment with cleaning function. Background Art

[0002] Under the background of the booming development of scientific and technological innovation and manufacturing in China, the importance of precision deep hole processing technology has become increasingly prominent in multiple fields. Whether it is in major strategic fields such as weapons, aerospace, and energy equipment, or in civilian fields such as medical devices, hydraulic cylinders, mold cooling holes, engine cooling oil holes, automobile crankshaft lubricating oil holes, and fuel injectors, the demand for deep hole processing shows a sharp upward trend.

[0003] However, there are many difficulties in deep hole drilling, which seriously restrict its development and application. First of all, the depth-diameter ratio of the processed hole is usually greater than five, which makes the tool holder cantilever of the deep hole processing tool too large and the tool rigidity extremely weak. During the processing, the hole is extremely prone to deviation, and it is difficult to ensure the processing accuracy. Secondly, when deep hole drilling, the tool is in a semi-closed state inside the deep hole, and it is very difficult for the cutting fluid to reach the cutting area smoothly, resulting in difficult tool heat dissipation and accelerated wear speed. This not only increases the tool cost, but also affects the processing efficiency and quality. Moreover, the chips generated by deep hole drilling are difficult to discharge from the chip flute of the tool. The friction between the chips and the hole wall is intensified, and the chip flute will be blocked, which will further increase the drilling torque and reduce the processing efficiency and quality.

[0004] Existing deep hole processing technologies have their own advantages and disadvantages. The gun drill has weak rigidity due to the existence of the V-shaped chip flute on the tool holder, and it cannot adopt large feed processing, so the drilling efficiency is relatively low. The ejector drill uses a double-tube chip removal for the tool rod, and the tool and tool rod structures are complex. The tool strength and chip removal cross-section are reduced, and chip jamming is more likely to occur during small hole processing. Although the DF system improves the chip removal efficiency by adding a negative pressure chip extractor, its versatility for the hole diameter processing range is relatively poor. Although the BTA drill has become the mainstream deep hole processing technology at present, it uses a single-layer round tube as the tool rod, which has good rigidity and a large chip removal cross-section. The high-pressure cutting fluid reaches the cutting area through the circular gap between the hole wall and the drill rod to take away the chips. Moreover, the tool uses a composite processing of tooth cutting and guide strip ironing, achieving the balance of the drilling tangential force and radial force, and ensuring the self-centering and self-guidance of the tool.

[0005] However, the BTA deep hole drilling equipment has obvious deficiencies. It belongs to a special machine tool. Affected by the requirements of deep hole processing, the bed body is huge and expensive, increasing the procurement cost and use cost of enterprises. Moreover, during the drilling process, an oily cutting fluid containing sulfur and phosphorus extreme pressure additives needs to be used, which seriously pollutes the processing environment and endangers the physical health of operating workers.

[0006] Therefore, it is necessary to provide a portable self-guided BTA deep hole drilling equipment with cleaning function to solve the above technical problems. Summary of the Invention

The exhaust pipe 22 is connected to the top end of the cold air inlet 23. The air inlet pipe 21 is connected to one side of the cold air inlet 23. The vortex tube 16 is connected to one end of the exhaust pipe 22;

[0047] The staggered tooth BTA drill bit 18 is arranged on one side of the gas energy storage tank 15.

[0048] One side of the right support plate 6 is provided with a bearing end cover 7.

[0049] The control panel 26 is installed on the surface of the housing 27.

[0050] The gear protection cover 19 is arranged on the surfaces of the first helical gear 9 and the second helical gear 10.

[0051] Both sides of the top of the housing 27 are connected with a first handle 25 and a second handle 28.

[0052] The workbench base 5 is the supporting foundation of the entire drilling platform. The slide 3 moves forward and backward accurately on the guide rail of the base. The slide 3 is matched with the spindle screw 4 and is driven by the feed motor 1 on the right side of the spindle screw 4. The top of the slide 3 is connected to the motor support frame 12 through the hexagon socket bolts. The top of the motor support frame 12 is connected to the spindle motor 11 through the hexagon socket bolts. The first bevel gear 9 and the drill rod clamp 20 are respectively fixed at the left and right ends of the motor support frame. The second bevel gear 10 is fixed on the left side of the spindle motor 11 through a key connection. The first bevel gear 9 and the second bevel gear 10 drive the drill rod clamp 20 to rotate through gear transmission. The right end of the drill rod clamp 20 is clamped with a drill rod 13, and the drill rod 13 passes through the gas energy storage box 15 to connect the staggered tooth BTA drill bit 18.

[0053] The high-pressure cold air supply device includes a vortex tube 16, a gas energy storage box 15, an air inlet pipe 21 and an exhaust pipe 22. 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 energy storage box 15. The cold air outlet 23 of the vortex tube 16 is fixed at the interface on the top of the gas energy 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.

[0054] The workpiece clamping device mainly consists of an electromagnetic chuck 24, which is fixed on the gas energy storage box 15. The electromagnetic chuck 24 and the gas energy storage box 15 are fixed on the platform of the right support plate 6 by hexagon socket bolts.

[0055] The workbench base 5 is the core supporting part of the entire equipment, providing a stable foundation for the drilling platform. The design of the base takes into account both the sturdiness of the structure and the lightness of the platform, making it suitable for portable operation. The slide 2 is installed on the base through precise guide rails, which can achieve precise forward and backward movement, ensuring stability and high precision during the drilling process. The slide 3 cooperates with the spindle screw 4 to form the main feed system of the platform. The drive of the spindle screw 4 is provided by the feed motor 1, which is installed on the left side of the spindle screw 4. The efficient operation of the feed system is achieved through precise control.

[0056] In order to ensure the structural stability of the drilling equipment and the high efficiency of power transmission, the top of the slide 6 is connected to the motor support frame 12 by a hexagon socket bolt, and the top of the motor support frame 12 is connected to the spindle motor 11 by a hexagon socket bolt. 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 a first bevel gear 9 and a 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, so that it rotates under the action of gear transmission. The left side of the spindle motor 11 is fixed with a second bevel gear 10 by a key connection. The two bevel gears jointly drive the drill rod clamp 20 through a gear transmission system to ensure the precise rotation of the drill rod clamp.

[0057] The right end of the drill pipe clamp 20 firmly holds the drill pipe 13. The drill pipe 13 passes through the gas energy storage tank 15 and is finally connected to the staggered-tooth BTA drill bit 18. The staggered-tooth BTA drill bit is connected to the drill pipe through a rectangular thread, significantly improving the replacement efficiency. Compared with the single-tooth BTA drill bit, the staggered-tooth BTA drill bit adopts a design with multiple cutting teeth staggered in distribution, effectively controlling the width of the chip during cutting and achieving a good chip-breaking effect. At the same time, the rake face of each cutting tooth is also equipped with a chip-breaking platform structure, which assists in chip breaking by increasing the bending deformation of the chip. This design not only optimizes the chip-breaking and chip-control capabilities but also greatly improves the chip evacuation efficiency of BTA deep-hole drilling, providing higher stability and machining quality for deep-hole machining.

[0058]

[0058] To effectively remove the chips during drilling and keep the equipment clean, the high-pressure cold air supply device plays a key role as an important part of the equipment. The vortex tube 16 and the gas energy storage tank 15 together constitute this device. The through holes on the left and right sides of the gas energy storage tank 15 are respectively fixed with the first sealing ring 14 and the second sealing ring 17 to ensure the airtightness of the air flow and the efficiency of the chip evacuation process. The cold air outlet 23 of the vortex tube 16 is fixed at the interface on the top of the gas energy storage tank 15. The high-pressure cold air flow can effectively reduce the temperature in the drilling area, reduce the thermal expansion phenomenon caused by high temperature, and at the same time use the high-pressure gas to discharge the chips. The 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 the effective control of the temperature in the drilling area and the smooth discharge of the chips.

[0059]

[0059] In terms of 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 through internal hexagonal bolts and the gas energy storage tank 15, and can adjust the suction force as needed to achieve rapid and firm adsorption of the workpiece. Considering the different shapes of the workpieces to be machined, the workpiece clamping device of the present invention can also install common fixtures 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 the stability of the workpiece during drilling and avoid affecting the drilling accuracy due to workpiece loosening.

[0060] As Figure 5As shown in the figure, the high-pressure cold air supply device is composed of a vortex tube and a gas energy storage tank. The vortex tube is a simple and efficient energy separation device, mainly composed of a nozzle, a vortex chamber, a separation orifice plate, and pipelines at both the cold and hot ends. Its working principle is that the gas compressed and cooled to room temperature enters the nozzle, expands and accelerates to the speed of sound in the nozzle, and then injects into the vortex chamber from the tangential direction to form a free vortex. The rotational angular velocity of the free vortex is greater closer to the center. Due to different angular velocities, friction is generated between the layers of the free vortex. The air flow angular velocity in the central part is the largest, and the friction result is that energy is transferred to the outer air flow with a lower angular velocity. The air flow in the central layer loses energy, has low kinetic energy, reduced speed, and reduced temperature, and is led out from one end through the orifice plate in the center of the vortex tube to obtain the cold air flow required for refrigeration. While the air flow in the outer part obtains momentum and increases in kinetic energy, and at the same time, it also frictions with the turbine tube wall, converting part of the kinetic energy into heat energy, which is led out from the other end of the vortex tube through a control valve to form a hot air flow.

[0061] In practical applications, the cold and hot distribution of the air flow can be optimized by adjusting the fluid ratio in the pipeline, so as to achieve the best refrigeration or heating effect. The high-pressure gas first expands and accelerates through the nozzle, enters the vortex chamber and rotates at an extremely high speed. The rotational speed can reach 1.0×10 6 RPM. When the high-speed air flow rotates along the pipe wall, it frictions with the pipe wall, resulting in a rapid increase in the gas temperature. This part of the hot air flow is discharged from the hot end of the vortex tube, and its temperature is higher than that of the original compressed gas. At the same time, part of the gas flows back along the pipeline center line to form a return air flow. This part of the air flow has a reverse effect on the vortex of the outer air flow and continuously conducts heat exchange, causing the air flow temperature to gradually decrease, and finally forming a cold air flow, which is discharged from the cold end of the vortex tube. This process is called the "vortex effect".
