Description

Technical Field

[0001] This invention relates to the field of deep hole drilling and boring machine technology, and more particularly to a chip removal structure for a deep hole drilling and boring machine. Background Technology

[0002] Deep hole drilling and boring machines are used to machine deep holes with a diameter-to-length (D / L) ratio of 1:6 or higher, such as deep holes in components like gun barrels, cannon barrels, and machine tool spindles. Deep hole drilling machines that rotate the workpiece (or rotate both the workpiece and the cutting tool simultaneously) are similar to horizontal lathes. There are general-purpose, special-purpose, and modified versions of ordinary lathes. For ease of cooling and chip removal, deep hole drilling machines are typically horizontally oriented. The main parameter of a deep hole drilling machine is its maximum drilling depth.

[0003] In the operation of deep hole drilling and boring machines, the conventional chip removal method is mostly external chip removal. Chips are removed through the gap between the drill rod and the workpiece. The drill rod of external chip removal is designed with a V-groove. During machining, high-pressure coolant pushes the chips along the groove to the outside of the hole to achieve chip removal. However, in the process of external chip removal, the chips need to be discharged through the gap between the drill rod and the workpiece. If the chip shape is irregular, the size is too large, or the cooling and lubrication conditions are not good, the chips may rub against the machined surface during the discharge process, resulting in scratches and affecting the machining quality.

[0004] Therefore, a chip removal structure for deep hole drilling and boring machines is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a chip removal structure for a deep hole drilling and boring machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a chip removal structure for a deep hole drilling and boring machine, comprising a drilling and boring machine bed and a drive assembly mounted on the drilling and boring machine bed, wherein a drill rod is provided on the drive assembly, a drill bit is fixedly connected to the drill rod, a workpiece is placed on the drilling and boring machine bed, and a chip removal assembly is provided on the drilling and boring machine bed for discharging metal chips generated during drilling, the chip removal assembly includes a mounting table, an annular gap for discharging cutting fluid into the cutting area is provided between the drill rod and the mounting table, and a discharge groove is formed in the drill rod for discharging drilling chips.

[0007] Preferably, an inlet pipe for discharging cutting fluid is fixedly installed in the mounting platform, and a bushing is fixedly installed in the mounting platform, with the end of the workpiece fitting against the bushing.

[0008] Preferably, the drill bit has several arc-shaped openings for the entry of cutting fluid, the interior of the drill bit is hollow, and the inner cavity of the drill bit is connected to the discharge groove.

[0009] Preferably, the drill rod is provided with an anti-clogging component, which is used to prevent metal debris from clogging the discharge chute and to clear blockages when they occur. The anti-clogging component includes a liquid storage tank fixedly installed on the drive assembly. The drill rod has a plurality of liquid inlet channels, and the end of each liquid inlet channel has a conical liquid outlet.

[0010] Preferably, a cylinder is fixedly installed on the liquid storage tank, and a push plate for applying pressure to the cutting fluid is fixedly connected to the cylinder, and the push plate is slidably connected inside the liquid storage tank.

[0011] Preferably, the liquid storage tank is rotatably connected to the drill rod, the liquid inlet tank is in communication with the interior of the liquid storage tank, and a one-way valve is fixedly installed in the liquid inlet tank.

[0012] Preferably, the tail end of the drill rod is provided with a collection assembly for collecting and separating metal chips and cutting fluid. The collection assembly includes an isolation cylinder fixedly installed on the drive assembly, a conical filter cylinder fixedly connected in the isolation cylinder, a conical guide block provided in the conical filter cylinder, and a discharge pipe rotatably connected to the drill rod for discharging the mixture of metal chips and cutting fluid into the isolation cylinder, and the discharge pipe is fixedly connected to the isolation cylinder.

[0013] Preferably, the bottom end of the conical filter cylinder is fixedly connected to a collection filter cylinder for storing metal scrap, and a conical block is slidably connected in the collection filter cylinder.

[0014] Preferably, an electric push rod is fixedly installed in the conical guide block, and a squeezing plate is fixedly installed on the electric push rod. The squeezing plate is used to move downward to squeeze and collect metal debris in the filter cartridge and reduce its volume.

[0015] Preferably, a bracket is fixedly connected to the collecting filter cartridge, and a telescopic rod is fixedly installed on the bracket. The telescopic rod is fixedly connected to the conical block, and a spring is fixedly installed in the telescopic rod. A separation cover is fixedly connected to the collecting filter cartridge.

[0016] The beneficial effects of this invention are: 1. This invention, by setting up a chip removal component, allows external cutting fluid to enter the cutting area through the annular gap and the arc-shaped opening on the drill bit during drilling of the workpiece. While lubricating and cooling the cutting area, it can also carry away the metal chips generated in the cutting area and flush them into the discharge groove inside the drill rod, and then discharge them through the discharge groove. The entire device allows the metal chips to be discharged from inside the drill rod, thereby avoiding the situation of scratching the drill hole by discharging them through the gap between the drill rod and the drill hole.

[0017] 2. In this invention, when the discharge trough discharges metal scraps through the anti-clogging component, some long, filamentous scraps will get stuck in the discharge trough. The cylinder pushes the push plate, allowing the cutting fluid in the reservoir to rush out of the one-way valve and into the inlet tank. The fluid is then sprayed out along the inner wall of the discharge trough through the conical nozzle, thereby impacting the filamentous metal scraps stuck in the discharge trough. This breaks the adhesion between the filamentous scraps and the inner wall of the drill rod, allowing them to gain kinetic energy and escape from the stuck position. This prevents the filamentous metal scraps from remaining in the discharge trough and causing blockage due to their inability to be discharged stably.

[0018] 3. By setting up a collection component, the present invention enables the mixture of metal scrap and cutting fluid to be discharged outward by the discharge trough. The mixture is evenly discharged onto the conical filter cylinder by the conical guide block, so that the conical filter cylinder can fully exert its filtration capacity to filter and separate the metal scrap. The cutting fluid slides down and is collected after passing through the conical filter cylinder. The metal scrap slides into the collection filter cylinder and is squeezed into shape and reduced in volume under the action of the extrusion plate before being automatically discharged downward, which is convenient for subsequent collection and storage.

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0023] It should be noted that, unless otherwise defined, the technical or scientific terms used in this invention should have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0024] like Figures 1 to 8As shown in the figure, a specific embodiment of the present invention provides a chip removal structure for a deep hole drilling and boring machine, including a drilling and boring machine bed 1 and a drive assembly 2 disposed on the drilling and boring machine bed 1. A drill rod 3 is disposed on the drive assembly 2, and a drill bit 4 is fixedly connected to the drill rod 3. A workpiece 5 is placed on the drilling and boring machine bed 1. The drive assembly 2 is prior art and can drive the drill rod 3 and the drill bit 4 to rotate, and push the drill rod 3 to move. A chip removal assembly is disposed on the drilling and boring machine bed 1. The chip removal assembly is used to discharge metal chips generated when the drill bit 4 drills. By setting the chip removal assembly, it can... The chip removal assembly is used to discharge metal chips generated by the drill bit 4 when drilling deep holes. The discharge is achieved through the inside of the drill rod 3, replacing the method of discharge through the gap between the drill rod 3 and the workpiece 5. This prevents the metal chips from scratching the workpiece 5. The chip removal assembly is used to discharge metal chips generated by the drill bit 4 when drilling. The chip removal assembly includes a mounting platform 6. An annular gap 7 for discharging cutting fluid into the cutting area is provided between the drill rod 3 and the mounting platform 6. A discharge groove 8 is provided in the drill rod 3 for discharging drilling chips.

[0025] The drill rod 3 is equipped with an anti-clogging component, which is used to prevent metal chips from clogging the discharge trough 8 and to clear blockages when they occur. When the drill bit 4 drills, the metal chips produced are of different sizes and are mixed with some long filamentous chips. During the chip removal process of the chip removal component, the long filamentous chips are large in size and elastic. When the cutting fluid pressure inside the drill rod 3 is insufficient, they are easy to get stuck in the inner cavity of the drill rod 3, thus forming a blockage. By setting the anti-clogging component, the long filamentous chips can be cleared in time to prevent them from clogging the drill rod 3. The anti-clogging component includes a liquid storage tank 9 fixedly installed on the drive assembly 2. The drill rod 3 has several liquid inlet grooves 10, and the end of the liquid inlet groove 10 has a conical liquid outlet 11.

[0026] The tail of the drill rod 3 is equipped with a collection component, which is used to collect and separate metal chips and cutting fluid. After the mixture of cutting fluid and metal chips generated during drilling is discharged outward, the collection component can collect the mixture and separate the two, thereby facilitating the recycling of metal chips and cutting fluid, so that the cutting fluid can be reused in subsequent processes. The collection component includes an isolation cylinder 12 fixedly installed on the drive assembly 2, a conical filter cylinder 13 fixedly connected in the isolation cylinder 12, and a conical guide block 14 provided in the conical filter cylinder 13.

[0027] like Figures 1 to 5As shown, specifically, an inlet pipe 15 for discharging cutting fluid is fixedly installed in the mounting platform 6. A bushing 16 is fixedly installed in the mounting platform 6, and the end of the workpiece 5 is in contact with the bushing 16. The drill bit 4 has several arc-shaped openings 17 for the entry of cutting fluid. The inside of the drill bit 4 is hollow, and the inner cavity of the drill bit 4 is connected to the discharge groove 8. When drilling the workpiece 5, the workpiece 5 is placed on the bed 1 of the drilling and boring machine and fixed so that the end of the workpiece 5 is in close contact with the bushing 16, maintaining a seal between the two. The drive assembly 2 drives the drill rod 3 and the drill bit 4 to rotate and drill the workpiece 5. During the drilling process, external cutting fluid is drawn from the outside by the pump body and other components and injected into the inlet pipe 15. The cutting fluid entering the inlet pipe 15 flows into the annular gap 7. The gap between the drill rod 3 and the mounting table 6 is an annular gap 7. At the same time, when the drill rod 3 drills the workpiece 5, the gap between the drill rod 3 and the hole wall is also an annular gap 7. At the right end of the annular gap 7, the drill rod 3 and the mounting table 6 are slidably connected and kept in close contact. As the cutting fluid continuously enters the annular gap 7, the cutting fluid gradually enters the cutting area at the end of the drill bit 4 through the arc-shaped opening 17 on the drill bit 4. The cutting fluid lubricates and cools the cutting area. As the cutting fluid continues to enter, it will be discharged into the interior of the drill bit 4. During the process of the cutting fluid being discharged from the cutting area of ​​the drill bit 4, it can wash away the metal chips generated during drilling, so that the mixture between the cutting fluid and the metal chips is discharged together into the discharge groove 8 in the drill rod 3 and discharged outward.

[0028] like Figures 1 to 7As shown, specifically, a cylinder 18 is fixedly installed on the reservoir 9, and a push plate 19 for applying pressure to the cutting fluid is fixedly connected to the cylinder 18. The push plate 19 is slidably connected inside the reservoir 9. The reservoir 9 is rotatably connected to the drill rod 3. The inlet channel 10 is connected to the inside of the reservoir 9, and a one-way valve 20 is fixedly installed in the inlet channel 10. In order to prevent the discharge channel 8 inside the drill rod 3 from being blocked by the clump of metal wire, cutting fluid is continuously injected into the reservoir 9 during the drilling process. At the same time, the amount of cutting fluid injected is monitored in real time. The process of injecting cutting fluid and monitoring the injection amount can be achieved by existing technology, and will not be described in detail here. When the cutting fluid in the reservoir 9 is about to be full, drilling and the discharge of cutting fluid into the inlet pipe 15 are stopped. Simultaneously, the cylinder 18 is activated to push the push plate 19 to move in the liquid storage tank 9. The push plate 19 pushes the cutting fluid in the liquid storage tank 9 and applies pressure to it. As the pressure increases, the cutting fluid breaks through the one-way valve 20 and gradually enters the liquid inlet tank 10. After flowing through the liquid inlet tank 10, the cutting fluid is sprayed outward through the conical liquid outlet 11. The cutting fluid sprayed outward from the conical liquid outlet 11 has a strong impact force. Its spray direction is along the inner wall of the discharge tank 8. Therefore, by spraying cutting fluid with a strong impact force, it can impact the metal wire-like debris stuck in the discharge tank 8, thereby breaking the adhesion between the wire-like debris and the inner wall of the drill rod 3, allowing it to gain kinetic energy and get out of the stuck position, preventing the metal wire-like debris from always staying in the discharge tank 8 and being unable to be stably discharged outward, thus causing blockage.

[0029] After the cutting fluid impacts the metal wire-like debris and clears and prevents blockage in the discharge trough 8, the drive cylinder 18 causes the push plate 19 to move and reset, the one-way valve 20 closes, and cutting fluid is injected into the storage tank 9 again to prepare for the next blockage prevention and clearing operation. At the same time, cutting fluid is injected into the inlet pipe 15 again to continue drilling.

[0030] like Figure 5 , Figure 6 and Figure 8As shown, specifically, a discharge pipe 21 for discharging a mixture of metal shavings and cutting fluid into the isolation cylinder 12 is rotatably connected to the drill rod 3, and the discharge pipe 21 is fixedly connected to the isolation cylinder 12. During the above process, the mixture of metal shavings and cutting fluid generated during drilling or unclogging is discharged through the discharge trough 8 to the discharge pipe 21, and then discharged through the discharge pipe 21 to the bottom isolation cylinder 12. In practical applications, the diameter of the bend in the discharge pipe 21 can be set larger to facilitate the discharge of the mixture of metal shavings and cutting fluid. A collection filter cylinder 22 for storing metal shavings is fixedly connected to the bottom of the conical filter cylinder 13. A conical block 23 is slidably connected in the collection filter cylinder 22, and a separation hood 29 is fixedly connected to the collection filter cylinder 22. After being discharged through the discharge pipe 21, the mixture of metal shavings and cutting fluid falls onto the conical guide block 14 and then slides and diffuses outwards, subsequently falling onto the conical filter cylinder 13 for filtration and separation. The guide block 14 allows the mixture of metal chips and cutting fluid to diffuse and slide, flowing evenly around the conical filter cartridge 13, preventing blockage at any point and maximizing the filtration capacity of the conical filter cartridge 13. The fluid then slides gradually from the periphery of the conical filter cartridge 13 towards the center. The cutting fluid in the mixture flows downward through the channel between the separation cover 29 and the isolation cylinder 12 after passing through the conical filter cartridge 13. Simultaneously, a cutting fluid recovery device is installed at the bottom of the conical filter cartridge 13 to collect the fluid. The metal chips filtered by the conical filter cartridge 13 slide to the center and fall into the collection filter cartridge 22 for storage. Meanwhile, some of the cutting fluid that falls into the collection filter cartridge 22 and adheres to the metal chips gradually seeps downward in the collection filter cartridge 22. Under the action of the conical block 23, the cutting fluid slides outward and is discharged through the filter holes on the collection filter cartridge 22, and can also be collected and reused.

[0031] An electric push rod 24 is fixedly installed in the conical guide block 14, and an extrusion plate 25 is fixedly installed on the electric push rod 24. The extrusion plate 25 is used to move downward to extrude and compress the metal debris in the collection filter cylinder 22, reducing its volume. A bracket 26 is fixedly connected to the collection filter cylinder 22, and a telescopic rod 27 is fixedly installed on the bracket 26. The telescopic rod 27 is fixedly connected to the conical block 23, and a spring 28 is fixedly installed in the telescopic rod 27. As the collection filter cylinder 22 gradually collects metal debris, the electric push rod 24 is activated to push the extrusion plate 25 downward, causing it to move downward. The extrusion plate 25 gradually approaches the metal debris in the collection filter cylinder 22 and applies pressure to it. Since the spring 28 exerts a force on the conical block 23 through the telescopic rod 27 and can maintain the stability of the conical block 23, the extrusion plate 25 can compress and shape the metal debris during the extrusion process, reducing the volume of larger debris and filamentous debris, making it easier to store later. After the volume of the metal debris has decreased and can no longer shrink, the extrusion plate 25... 5. After the continuously applied pressure gradually overcomes the force exerted by the spring 28 on the conical block 23, the spring 28 and the telescopic rod 27 gradually contract, and the conical block 23 moves downward until the bottom part of the conical block 23 disengages from the collecting filter cylinder 22. At this point, the conical block 23 no longer obstructs the metal debris stored in the collecting filter cylinder 22, and the metal debris slides outward and falls through the gap between the conical surface of the conical block 23 and the collecting filter cylinder 22. The compressed metal debris then flows downward through the inner cavity of the separation cover 29. The metal scrap and cutting fluid mixture is separated and collected by a collection device at the bottom. After the metal scrap in the collection filter cartridge 22 is recovered, the electric push rod 24 is reversed to move the extrusion plate 25 upward and reset. At this time, the conical block 23 is pushed upward by the telescopic rod 27 under the reaction force of the spring 28 and re-enters the collection filter cartridge 22, forming a seal at the bottom of the collection filter cartridge 22, which facilitates the subsequent collection of metal scrap by the collection filter cartridge 22.
