Description

Technical Field

[0001] This invention belongs to the field of workpiece turning, specifically a turning device for producing chisels for hydraulic breakers. Background Technology

[0002] A hydraulic breaker is a hydraulic impact device installed on construction machinery such as excavators. Commonly known as a "crash gun," it is used to efficiently break hard materials such as rocks and concrete. The chisel is its core vulnerable component. As a force transmission rod, the front end directly impacts the material to be broken. It is made of high-strength alloy steel through forging, heat treatment, and precision machining. It must have extremely high impact toughness, wear resistance, and fatigue resistance. Its quality directly determines the breaking efficiency and service life.

[0003] The machining of the drill rod begins with cutting the alloy steel bar into blanks, which are then forged after being heated by medium frequency to optimize the internal fiber structure. Subsequently, quenching and tempering heat treatments are performed to obtain high hardness and toughness. The machining stage mainly involves rough and finish turning of the outer diameter, turning of the rod head contour, grooving, and threading using a CNC lathe.

[0004] Traditional chisel turning equipment often uses CNC machine tools for processing. However, traditional CNC machine tools generally use complex and precise equipment such as robotic arms to control the loading and unloading of chisels. However, the loading and unloading process of robotic arms not only requires a precise control system and high investment costs, but also the robotic arm is prone to friction with the parts in the lathe when it extends into the processing area, affecting the entire production process. Moreover, once the mechanical equipment malfunctions, it can not only damage the lathe, but also cause the entire production process to stop, which has a significant impact on the entire production process.

[0005] Therefore, the present invention provides a device for turning drill rods for producing hydraulic breakers. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a machining table for producing chisel rods for hydraulic breakers, which includes a machining table with an adjustable tilt angle. A sealing plate is fixedly connected to one side of the machining table. A machining cavity is provided inside the machining table. A movable turret is provided inside the machining cavity. The turret includes a rotatable docking plate. Multiple turning tool holders and two locking rings are fixedly connected to the outside of the docking plate. A first spindle is installed on the inner wall of one side of the machining table. A movable second spindle is provided inside the machining cavity. Electric chucks are fixedly connected to the drive ends of both the first and second spindles. A feed pipe for providing chisel rods is fixedly connected through the sealing plate. This setup not only enables highly efficient chisel turning, but also allows for rapid and stable transfer of the chisel under gravity by adjusting the tilt of the machining table. Compared to traditional methods using robotic arms, this is not only more convenient and cost-effective, but also keeps the entire equipment clean and tidy. It eliminates the risk of parts collisions that can occur during material handling by robotic arms, and the gravity-guided chisel transport process is stable and reliable, significantly reducing the risk of misalignment and mechanical failures, thus improving the equipment's operational stability.

[0008] Preferably, an arc-shaped drive disk is fixedly connected to the bottom of the processing table, and a support base is provided below the drive disk. The bottom of the drive disk is slidably engaged with the top of the support base, and a drive component for moving the drive disk is fixedly connected to the top of the support base. During operation, the drive disk is moved by the drive component on the top of the support base. In conjunction with the arc shape of the drive disk, the entire processing table is tilted, thereby completing the function of guiding the chisel transfer by gravity. The drive component can be a combination of electric gears and cleats. Electric gears are fixedly connected to both ends of the top of the drive disk, and a groove is cut in the bottom of the drive disk, and cleats that mesh with the electric gears are installed. As the electric gears rotate, the entire drive disk is moved. Different drive components can also be used, as long as the processing table is tilted at a certain angle.

[0009] Preferably, two sets of lead screw and nut mechanisms are fixedly connected to the ground inside the machining table. An electric slide rail for translating the turret is installed at the bottom of the turret. The moving ends of the two lead screw and nut mechanisms are fixedly connected to the electric slide rail and the second spindle table, respectively. During operation, the lead screw and nut mechanisms control the electric slide rail to translate, and the electric slide rail in turn controls the entire turret to translate. At the same time, the docking plate can rotate, so that the turning tool holder and locking ring outside the docking plate can be moved to any position to complete the turning machining and receiving of the chisel.

[0010] Preferably, the second spindle table consists of a bottom support platform and an upper deflection platform, which are rotatably connected by a hinge. A winding platform is fixedly connected inside the upper deflection platform, and a steel cable fixed to the top of the bottom support platform is wound around the outside of the winding platform. During operation, to facilitate the transfer of the finished drill rod, after the drill rod is processed, the winding platform slowly releases the steel cable. Since the second spindle table is tilted outward, when the upper part of the upper deflection platform loses tension, it will rotate outward until it is in contact with the outside of the bottom support platform. At this time, the electric chuck is released, and the drill rod will fall directly in the tilting direction. Since the upper deflection platform has deviated from the axis of the first spindle table during this rotation, the finished drill rod falls outside the processing table, which is convenient for recovery and will not affect the internal environment of the processing cavity. After recovery, the winding platform is activated to recover the steel cable and pull the upper deflection platform back into position. A positioning lock is also installed between the upper deflection platform and the bottom support platform to ensure that the two are fixed and stable.

[0011] Preferably, a recycling cover is fixed to the front end of the processing table, a discharge port is opened on one side of the recycling cover, a recycling rail is fixed to the front end of the processing table, an observation window is also fixed to the front end of the processing table, and a power table for driving the first spindle table is fixed to one side of the processing table. During operation, after the upper deflection table rotates, it will move the chisel into the recycling cover. The released chisel passes through the discharge port and falls into the recycling rail, sliding outward along the recycling rail to facilitate the recycling of finished products.

[0012] Preferably, the turret includes a power base, and a servo motor is fixedly connected inside the power base. The output end of the servo motor is fixedly connected to the docking plate. The locking ring is arranged in a through-type configuration, and multiple adjustable arms capable of translation are installed on the inner ring of the locking ring. During operation, the docking plate is precisely rotated by the servo motor to ensure that the drill bit can be transported smoothly and that the turning tool table can be moved to the required position. When the drill bit enters the locking ring, the multiple adjustable arms are activated to move towards the center, which can fix the drill bit and facilitate the transfer of the drill bit to the first spindle table.

[0013] Preferably, the front end of the feed tube is provided with a movable ring capable of translation, and the front end of the movable ring is provided with multiple positioning arms capable of translation. During operation, a number of chisel roughs can be placed in the feed tube and blocked by the multiple positioning arms. When a chisel is needed, the positioning arms are moved, and the chisel slides under the action of gravity. The positioning arms rub the chisel from the side to assist in the stable movement of the chisel. At the same time, the adjusting arm in the locking ring provides assistance. With the assistance of two sets of clamping parts, and the positioning arm itself being able to translate, the chisel can be adjusted to the required position and fixed by clamping and releasing, which facilitates the subsequent docking process between the chisel and the first spindle table.

[0014] Preferably, a positioning ring is fixedly connected to the rear end of the feed pipe, and an inner ring tube is slidably engaged inside the feed pipe. The length of the inner ring tube is the same as the length of the feed pipe, and the outer diameter of the inner ring tube is smaller than the inner diameter of the feed pipe. During operation, when it is necessary to process drill rods of different diameters, the inner ring tube can be fixed in the feed pipe to reduce its own inner diameter, so that the drill rod of the corresponding diameter can be adapted to enter the feed pipe for transportation, ensuring the sliding stability of the drill rod and ensuring the smooth docking process. After the inner ring tube is fixed, the positioning ring is used to fix the inner ring tube to ensure the connection stability.

[0015] Preferably, the outer side of the feed pipe is provided with multiple slots, and the outer side of the moving ring is fixedly connected with multiple drive platforms. The drive end of the drive platform is located inside the slot and is in contact with the slot. During operation, the end of the drive platform can be provided with an electric wheel that is in contact with the slot. The entire moving ring is controlled to move by driving the electric wheel. With the fixing of the positioning arm, the function of adjusting the position of the drill rod is completed.

[0016] Preferably, the bottom surface of the processing table is provided with two sets of telescopic baffles. The telescopic baffles are located above the lead screw and nut mechanism and are respectively attached to the bottom surface of the electric slide rail and the bottom support table. A chip discharge port is opened on the bottom side of the processing table near the power table. During operation, the telescopic baffles are arranged in multiple layers. Using the position of the electric slide rail and the second spindle table, the bottom lead screw and nut mechanism is always hidden below, reducing the impact of processing chips on the equipment. Because the processing table is tilted, the chips generated during processing and the cooling water will be concentrated at the bottom chip discharge port, which facilitates the discharge of chips.

[0017] The beneficial effects of this invention are as follows: 1. The present invention discloses a chisel turning device for producing hydraulic breakers. By adjusting the tilt of the processing table, the chisel transportation and transfer process is completed quickly and stably under the action of gravity. Compared with traditional transfer methods such as using robotic arms, it is not only more convenient to operate and less expensive, but also makes the entire equipment simple and clean. It eliminates the accidental collision of parts that may occur during the feeding and unloading process of robotic arms. At the same time, the process of guiding the chisel transportation by gravity is stable and reliable, which greatly reduces the installation misalignment and mechanical failure caused by mechanical failure, and improves the operational stability of the equipment.

[0018] 2. The chisel turning device for producing hydraulic breakers described in this invention facilitates the transfer of finished chisels. After the chisel is processed, the winding table slowly releases the steel cable. Since the second spindle table is tilted outwards, when the upper deflector loses tension, it will rotate outwards until it is in contact with the outer side of the bottom support table. At this time, the electric chuck is released, and the chisel will fall directly in the tilting direction. Since the upper deflector has deviated from the axis of the first spindle table during this rotation, the finished chisel falls off the outer side of the processing table, which is convenient for recovery and will not affect the internal environment of the processing chamber. After recovery, the winding table is activated to retrieve the steel cable and pull the upper deflector back into place. A positioning bolt is also installed between the upper deflector and the bottom support table to ensure their stability. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 6As shown in the embodiment of the present invention, a chisel turning device for producing hydraulic breakers includes a machining table 1 with an adjustable tilt angle. A sealing plate 2 is fixedly connected to one side of the machining table. The machining table 1 has a machining cavity inside. A movable turret 12 is provided inside the machining cavity of the machining table 1. The turret 12 includes a rotatable docking plate 16. Multiple turning tool holders 18 and two locking rings 19 are fixedly connected to the outer side of the docking plate 16. A first spindle table 14 is installed on the inner wall of one side of the machining table 1. A movable second spindle table 11 is provided inside the machining cavity. Electric chucks 24 are fixedly connected to the driving ends of both the first spindle table 14 and the second spindle table 11. A feed pipe 9 for providing chisels is fixedly connected through the sealing plate 2. The forged and heat-treated drill rod blank is placed into the feed pipe 9. The entire machining table 1 is tilted, and the feed pipe 9 is located at its highest point outside the machining table 1. Under the action of gravity, the drill rod blank slides downward and moves into the machining cavity. The docking plate 16 is rotated by the turret 12, moving the locking ring 19 to be flush with the feed pipe 9. The end of the feed pipe 9 is equipped with an opening and closing valve to control the release of the drill rod. After release, the drill rod enters the locking ring 19 and is fixed. At the same time, the docking plate 16 is rotated, rotating the locking ring 19 to be aligned with the first spindle table 14, controlling the entire turret 12 to move closer to the first spindle. The first spindle table 14 is used to fix the chisel rod to the electric chuck 24. After fixing, the turret 12 is moved away, and the first spindle table 14 controls the chisel rod to rotate, while simultaneously controlling the mating plate 16 to rotate, so that the required turning tool table 18 is rotated close to the chisel rod. Different types of turning tools are installed at the ends of different turning tool tables 18 for roughing and finishing the chisel rod. During the fixing of the first spindle table 14, the main focus is on machining the head and front surface of the chisel rod. Before the machining is finished, the electric chuck 24 of the second spindle table 11 is controlled to rotate at the same speed as the electric chuck 24 of the first spindle table 14. When the first half of the chisel rod is... After partial machining is completed, the second spindle table 11 is moved to align with the first spindle table 14. While keeping the two electric chucks 24 relatively stationary, the chisel is hinged. Then, the second spindle table 11 is retracted, and simultaneously the turret 12 is moved, allowing the cutting tool at the end of the turning tool holder 18 to contact the rear end of the chisel for machining. This allows for turning the rear surface of the chisel and machining grooves such as threaded slots for fixing at the rear end. After machining is complete, the second spindle table 11 stops and moves outward, offsetting the axial position of the first spindle table 14. At this point, the second spindle table 11 is released from its fixed position, allowing the chisel to slide outward under gravity. The drill bit can be retrieved at the sliding position. This design not only enables efficient drill bit turning, but also allows for rapid and stable transfer of the drill bit under gravity by adjusting the tilt of the machining table 1. Compared to traditional transfer methods using robotic arms, this is not only more convenient and cost-effective, but also keeps the entire equipment clean and tidy. It eliminates the possibility of accidental collisions between parts during material feeding and unloading by robotic arms. Furthermore, the gravity-guided drill bit transport process is stable and reliable, greatly reducing the risk of installation misalignment and mechanical failures caused by mechanical malfunctions, and improving the operational stability of the equipment.

[0023] An arc-shaped drive disk 6 is fixedly connected to the bottom of the processing table 1. A support base 7 is provided below the drive disk 6. The bottom of the drive disk 6 is slidably engaged with the top of the support base 7. A drive component for moving the drive disk 6 is fixedly connected to the top of the support base 7. During operation, the drive plate 6 is moved by the drive component on the top of the support base 7. With the arc-shaped setting of the drive plate 6, the entire processing table 1 is tilted, thereby completing the function of guiding the chisel transfer by gravity. The drive component can be a combination of electric gear and cleaver. The top two ends of the drive plate 6 are fixed with electric gears, and the bottom of the drive plate 6 is slotted and fitted with cleavers that mesh with the electric gears. As the electric gears rotate, the entire drive plate 6 is moved. Different drive components can also be used, as long as the processing table 1 is tilted at a certain angle.

[0024] The machining table 1 has two sets of lead screw and nut mechanisms fixed to the ground inside. The bottom of the turret 12 is equipped with an electric slide rail 15 for the turret 12 to move. The moving ends of the two lead screw and nut mechanisms are fixed to the electric slide rail 15 and the second spindle table 11, respectively. During operation, the electric slide rail 15 is controlled to move horizontally via the lead screw and nut mechanism. The electric slide rail 15 then controls the entire turret 12 to move horizontally. At the same time, the docking plate 16 can rotate. In this way, the turning tool table 18 and the locking ring 19 outside the docking plate 16 can move to any position to complete the turning process and receive the chisel.

[0025] The second spindle stage 11 consists of a bottom support stage 21 and an upper deflection stage 22. The bottom support stage 21 and the upper deflection stage 22 are rotatably connected by a hinge. A winding stage 23 is fixedly connected inside the upper deflection stage 22, and a steel cable fixedly connected to the top of the bottom support stage 21 is wound on the outside of the winding stage 23. During operation, to facilitate the transfer of the finished drill rod, after the drill rod is processed, the winding table 23 slowly releases the steel cable. Since the second spindle table 11 is tilted outward, when the upper deflection table 22 loses tension, it will rotate outward until it is in contact with the outer side of the bottom support table 21. At this time, the electric chuck 24 is released, and the drill rod will fall directly in the tilting direction. Since the upper deflection table 22 has deviated from the axis of the first spindle table 14 during this rotation, the finished drill rod falls to a position slightly outside the processing table 1, which is convenient for retrieval and will not affect the internal environment of the processing chamber. After retrieval, the winding table 23 is activated to retrieve the steel cable and pull the upper deflection table 22 back into position. A positioning bolt is also installed between the upper deflection table 22 and the bottom support table 21 to ensure that the two are fixed and stable.

[0026] The front end of the processing table 1 is fixedly connected to a recycling cover 5, and a discharge port is opened on one side of the recycling cover 5. The front end of the processing table 1 is fixedly connected to a recycling rail 8, and the front end of the processing table 1 is also fixedly connected to an observation window 4. A power table 3 for driving the first spindle table 14 is fixedly connected to one side of the processing table 1. During operation, the upper deflector 22 rotates and moves the drill rod into the recycling hood 5. The released drill rod passes through the discharge port and falls into the recycling rail 8, sliding outward along the recycling rail 8 to facilitate the recycling of finished products.

[0027] The turret 12 includes a power base 17, a servo motor is fixedly connected inside the power base 17, the output end of the servo motor is fixedly connected to the docking plate 16, the locking ring 19 is arranged in a front-to-back through manner, and multiple adjusting arms 20 capable of translation are installed on the inner ring of the locking ring 19. During operation, the servo motor controls the precise rotation of the docking plate 16 to ensure smooth transport of the drill rod and that the turning table 18 can be moved to the required position. When the drill rod enters the locking ring 19, multiple adjusting arms 20 are activated to move towards the center, which can fix the drill rod and facilitate its transfer to the first spindle table 14.

[0028] The front end of the feed pipe 9 is provided with a movable ring 28 that can be translated, and the front end of the movable ring 28 is provided with a plurality of positioning arms 29 that can be translated. During operation, a number of rough chisels can be placed in the feed pipe 9 and blocked by multiple positioning arms 29. When a chisel is needed, the positioning arms 29 are moved and the chisel slides under the action of gravity. The positioning arms 29 rub the chisel from the side to assist in the stable movement of the chisel. At the same time, the adjusting arm 20 in the locking ring 19 provides assistance. With the assistance of two sets of clamping parts, and the positioning arm 29 itself can move horizontally, the chisel can be adjusted to the required position and fixed by clamping and releasing, which facilitates the subsequent docking process between the chisel and the first spindle table 14.

[0029] The rear end of the feed pipe 9 is fixedly connected to a positioning ring 10, and an inner ring tube 25 is slidably engaged inside the feed pipe 9. The length of the inner ring tube 25 is the same as the length of the feed pipe 9, and the outer diameter of the inner ring tube 25 is smaller than the inner diameter of the feed pipe 9. During operation, when it is necessary to process drill rods of different diameters, the inner ring tube 25 can be fixed in the feed tube 9 to reduce its inner diameter, so that the drill rod of the corresponding diameter can be adapted to enter the feed tube 9 for transportation, ensuring the sliding stability of the drill rod and ensuring the smooth docking process; after the inner ring tube 25 is fixed, the positioning ring 10 is used to fix the inner ring tube 25 to ensure the connection stability.

[0030] The feed pipe 9 has multiple slots 26 on its outer side, and multiple drive platforms 27 are fixedly connected to the outer side of the moving ring 28. The drive end of the drive platform 27 is located inside the slot 26 and is in transmission contact with the slot 26. During operation, the end of the drive table 27 can be equipped with an electric wheel that fits into the slot 26. Driven by the electric wheel, the entire moving ring 28 is moved. With the fixation of the positioning arm 29, the function of adjusting the position of the drill rod is completed.

[0031] The bottom surface of the processing table 1 is provided with two sets of telescopic baffles 13. The telescopic baffles 13 are located above the lead screw nut mechanism and are respectively attached to the bottom surface of the electric slide rail 15 and the bottom support table 21. The bottom of the processing table 1 near the power table 3 is provided with a chip discharge port 30. During operation, the telescopic baffle 13 is multi-layered. Using the positions of the electric slide rail 15 and the second spindle table 11, the bottom lead screw nut mechanism is always hidden below, reducing the impact of machining chips on the equipment. Because the machining table 1 is tilted, the machining chips and cooling water are concentrated at the bottom chip discharge port 30, which facilitates the discharge of chips.

[0032] During operation, the forged and heat-treated drill rod blank is placed into the feed pipe 9. The entire machining table 1 is tilted, and after tilting, the feed pipe 9 is located at its highest point outside the machining table 1. Under the action of gravity, the drill rod blank slides downward and moves into the machining cavity. The docking plate 16 is rotated by the turret 12, moving the locking ring 19 to be flush with the feed pipe 9. An opening and closing valve is provided at the end of the feed pipe 9 to control the release of the drill rod. After release, the drill rod enters the locking ring 19 and is fixed. At the same time, the docking plate 16 rotates, rotating the locking ring 19 to be aligned with the first spindle table 14, controlling the entire turret 12 to move closer to the first spindle table 14. A first spindle table 14 is used to fix the chisel rod to the electric chuck 24. After fixing, the turret 12 is moved away, and the first spindle table 14 controls the chisel rod to rotate, while simultaneously controlling the mating plate 16 to rotate, so that the required turning tool table 18 is rotated close to the chisel rod. Different types of turning tools are installed at the ends of different turning tool tables 18 for roughing and finishing the chisel rod. During the fixing of the first spindle table 14, the main focus is on machining the head and front surface of the chisel rod. Before the machining is finished, the electric chuck 24 of the second spindle table 11 is controlled to rotate at the same speed as the electric chuck 24 of the first spindle table 14. When the chisel rod... After the first part of the machining is completed, the second spindle table 11 is moved to align with the first spindle table 14. While keeping the two electric chucks 24 relatively stationary, the chisel is hinged. Then, the second spindle table 11 is retracted, and the turret 12 is moved simultaneously, allowing the cutting tool at the end of the turning tool holder 18 to contact the rear end of the chisel for machining. This allows for turning the rear surface of the chisel and machining grooves such as threaded slots for fixing the chisel. After machining is complete, the second spindle table 11 stops and moves outward, offsetting the axis position of the first spindle table 14. At this point, the second spindle table 11 is released from its fixed position, allowing the chisel to slide outward under gravity. Simply retract the drill bit at the sliding position. This setup not only enables efficient drill bit turning, but also allows for rapid and stable transfer of the drill bit under gravity by adjusting the tilt of the machining table 1. Compared to traditional transfer methods using robotic arms, this is not only more convenient and cost-effective, but also keeps the entire equipment internally simple and tidy. It eliminates the possibility of accidental collisions between parts during material feeding and unloading by robotic arms. Furthermore, the gravity-guided drill bit transport process is stable and reliable, significantly reducing installation misalignment and mechanical failures caused by mechanical malfunctions, and improving the operational stability of the equipment.

[0033] The drive plate 6 is moved by the drive component at the top of the support base 7. With the arc shape of the drive plate 6, the entire processing table 1 is tilted, thus completing the function of guiding the chisel transfer by gravity. The drive component can be a combination of electric gear and cleaver. The electric gear is fixed to both ends of the top of the drive plate 6. A groove is made at the bottom of the drive plate 6 and a cleaver that meshes with the electric gear is installed. As the electric gear rotates, the entire drive plate 6 is moved. Different drive components can also be used, as long as the processing table 1 is tilted at a certain angle.

[0034] The electric slide rail 15 is controlled to move by the lead screw and nut mechanism, and the electric slide rail 15 in turn controls the entire turret 12 to move. At the same time, the docking plate 16 can rotate. In this way, the turning tool table 18 and the locking ring 19 outside the docking plate 16 can be moved to any position to complete the turning process and receive the chisel.

[0035] To facilitate the transfer of the finished drill rod, after the drill rod is processed, the winding table 23 slowly releases the steel cable. Since the second spindle table 11 is tilted outward, when the upper deflector table 22 loses tension, it will rotate outward until it is in contact with the outer side of the bottom support table 21. At this time, the electric chuck 24 is released, and the drill rod will fall directly in the tilting direction. Since the upper deflector table 22 has deviated from the axis of the first spindle table 14 during this rotation, the finished drill rod falls to a position slightly outside the processing table 1, which is convenient for retrieval and will not affect the internal environment of the processing chamber. After retrieval, the winding table 23 is activated to retrieve the steel cable and pull the upper deflector table 22 back into position. A positioning bolt is also installed between the upper deflector table 22 and the bottom support table 21 to ensure that the two are fixed and stable.

[0036] After the upper deflection table 22 rotates, it will move the drill rod to the recycling hood 5. The released drill rod passes through the discharge port and falls into the recycling rail 8, sliding outward along the recycling rail 8 to facilitate the recycling of finished products.

[0037] The servo motor controls the precise rotation of the docking plate 16 to ensure smooth transport of the drill rod and allows the turning table 18 to move to the required position. Once the drill rod enters the locking ring 19, multiple adjusting arms 20 are activated to move towards the center, which can fix the drill rod and facilitate its transfer to the first spindle table 14.

[0038] A number of rough chisels can be placed in the feed pipe 9 and blocked by multiple positioning arms 29. When a chisel is needed, the positioning arms 29 are moved and the chisel slides under the action of gravity. The positioning arms 29 rub the chisel from the side to assist in the stable movement of the chisel. At the same time, the adjusting arm 20 in the locking ring 19 provides assistance. With the assistance of two sets of clamping parts, and the positioning arm 29 itself can move horizontally, the chisel can be adjusted to the required position and fixed by clamping and releasing, which facilitates the subsequent docking process between the chisel and the first spindle table 14.

[0039] When it is necessary to process drill rods of different diameters, the inner ring tube 25 can be fixed in the feed tube 9 to reduce its inner diameter, so that the drill rod of the corresponding diameter can be adapted to enter the feed tube 9 for transportation, ensuring the sliding stability of the drill rod and ensuring the smooth docking process; after the inner ring tube 25 is fixed, the positioning ring 10 is used to fix the inner ring tube 25 to ensure the connection stability.

[0040] The end of the drive table 27 may be equipped with an electric wheel that fits into the slot 26. Driven by the electric wheel, the entire moving ring 28 is moved. With the fixation of the positioning arm 29, the function of adjusting the position of the drill rod is completed.

[0041] The telescopic baffle 13 is multi-layered. Using the positions of the electric slide rail 15 and the second spindle table 11, the bottom lead screw nut mechanism is always hidden below, reducing the impact of machining chips on the equipment. Because the machining table 1 is tilted, the machining chips and cooling water are concentrated at the bottom chip discharge port 30, which facilitates the discharge of chips.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
