Description

Technical Field

[0001] This invention relates to the field of equipment manufacturing technology, specifically a precision machining equipment suitable for deep cavity castings or deep hole castings. Background Technology

[0002] In the field of equipment manufacturing, castings with deep cavities and deep holes are core basic parts for industries such as hydraulics, engineering machinery, and energy equipment. The precision machining of the inner holes of such parts generally relies on deep hole drilling and boring equipment. Due to the large overhang length and high length-to-diameter ratio of the drill rod during deep hole machining, radial chatter and axial runout are easily generated when the drill rod rotates at high speed, which directly affects the shape and position accuracy of the hole and the surface quality of the inner wall.

[0003] Currently, the industry typically adds a follower or guide sleeve structure to the outside of the drill rod to provide radial support for the drill rod through bushings and other structures, thereby improving the rigidity of the drill rod and suppressing machining chatter. However, the installation process of the guide sleeve is relatively cumbersome. When using drill rods of different specifications, the guide sleeve needs to be manually disassembled and replaced. In addition, the ribbon-like chips generated during machining are easy to wrap around and adhere to the outer surface of the drill rod, which can cause problems such as scratches on the drill rod surface, wear of the guide sleeve, and decreased spindle positioning accuracy. Summary of the Invention

[0004] To address the above problems, the present invention provides the following technical solution: A finishing device suitable for deep cavity castings or deep hole castings includes a deep hole drilling and boring machine.

[0005] In the above technical solution, the reciprocating scraping assembly includes positioning rods disposed at the bottom of both sides of the inclined pusher. A removal toothed plate is fixedly connected to the bottom of the positioning rods. A limiting sleeve is installed at the bottom of the removal toothed plate. A Z-shaped square column is slidably connected inside the limiting sleeve. The limiting sleeve is slidably connected to the surface of the Z-shaped square column. The left side of the Z-shaped square column is installed on the right side of the U-shaped plate.

[0006] In the above technical solution, the adjustment assembly includes an electric push rod fixedly installed inside the cage on the front and rear sides. The output end of the electric push rod extends to the left side of the cage and is fixedly installed with a ring plate. The ring plate is sleeved on the surface of the slide rod. An inclined plate is fixedly installed on the right side of the ring plate. The surface of the inclined plate is in contact with the surface of the inclined square column. Connecting blocks are fixedly installed on the left side of the U-shaped plate and the left side of the cage. A tension spring is fixedly installed on the surface of the connecting block.

[0007] In the above technical solution, the cooling booster spray chip removal component includes a booster housing fixedly installed on the right side of the U-shaped plate, an inlet pipe connected to the rear side of the booster housing, a booster blade fixedly installed on the surface of the drive shaft, the booster blade being located inside the booster housing, and a spray duct connected to the right side of the booster housing.

[0008] In the above technical solution, the jet-assisted chip removal component includes an air storage housing fixedly installed on the right side of the U-shaped plate. The air storage housing is located in front of the pressurization housing. A fan blade is fixedly installed on the surface of the drive shaft. The fan blade is located inside the air storage housing. An air guide pipe is connected to the right side of the air storage housing. An air curtain protective ring is fixedly installed on the right side of the retainer. A telescopic pipe is connected to the surface of the air guide pipe. The front end of the telescopic pipe is connected to the air curtain protective ring.

[0009] In the above technical solution, a stabilizing plate is fixedly installed on the surface of both the injection duct and the air duct, and the left side of the stabilizing plate is fixedly installed on the right side of the U-shaped plate.

[0010] In the above technical solution, an arc-shaped protective plate is provided on the top of the inclined push wheel, and the surface of the arc-shaped protective plate is fixedly installed on the surface of the U-shaped plate.

[0011] In the above technical solution, a limiting block is fixedly installed on the surface of the inclined plate, and a reinforcing ring is fixedly installed on the right side of the ring plate, with the surface of the reinforcing ring fixedly connected to the surface of the inclined plate.

[0012] In the above technical solution, a filter sleeve is fixedly installed on the left side of the surface of the gas storage shell, and the air inlet of the gas storage shell is located inside the filter sleeve.

[0013] In the above technical solution, buffer pads are fixedly installed on the front and rear sides of the right side of the retainer. The buffer pads are sleeved on the surface of the slide rod and are located on the right side of the electric push rod.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention uses an electric push rod to move the ring plate to the right along the slide rod, which drives the inclined plate to push the inclined square column radially forward, so that the clamping roller is in contact with the drill rod surface to complete the centering support. The rotation of the drill rod drives the clamping roller and the transmission shaft to rotate synchronously through friction, which drives the inclined push wheel to drive the reciprocating scraping component to reciprocate along the Z-shaped square column axial direction, so that the removal tooth plate continuously scrapes the chips wrapped around the drill rod surface, effectively improving the chip removal efficiency and drill rod operation stability in deep hole machining.

[0015] Furthermore, when the drill rod rotates and drives the drive shaft to rotate synchronously, the booster blades fixed on the surface of the drive shaft rotate at high speed inside the booster housing along with the drive shaft. The cutting fluid continuously enters the booster housing through the inlet pipe. After the booster blades perform centrifugal work to complete secondary pressurization, it is directionally delivered to the bottom of the deep hole cavity through the injection conduit. The high-pressure cutting fluid carries the chips and is quickly discharged along the chip removal channel, effectively increasing the chip flushing velocity at the bottom of the deep hole and solving the problems of large pressure loss along the hole and chip accumulation at the bottom of the hole in deep holes with large length-to-diameter ratios.

[0016] Furthermore, when the drill rod rotates and drives the drive shaft to rotate synchronously, the fan blades fixed to the surface of the drive shaft rotate at high speed inside the air storage shell, drawing in outside air and generating high-pressure airflow. The airflow is then transported to the air curtain protection ring through the air guide pipe and the telescopic pipe in sequence. Through the circumferential nozzles, a continuous annular air curtain is formed at the workpiece orifice, which helps to block the splashing and diffusion of chips and cutting fluid. The airflow is blown from the air guide pipe to the deep hole of the workpiece, helping to push the chips in the hole to be discharged outward at an accelerated speed, effectively improving chip removal efficiency and improving the processing site environment.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1 to 7 As shown, the present invention provides a finishing equipment suitable for deep cavity castings or deep hole castings, including a deep hole drilling and boring machine 1. Vertical plates 2 are installed on both the front and rear sides of the spindle box of the deep hole drilling and boring machine 1. A workpiece support frame 3 is slidably connected to the top of the deep hole drilling and boring machine 1. Slide rods 4 are installed on both the front and rear sides of the left side of the workpiece support frame 3. The vertical plates 2 are sleeved on the surface of the slide rods 4. A retainer 5 is slidably connected to the surface of the slide rods 4. Connecting frames 6 are installed on both the front and rear sides of the bottom of the retainer 5. The bottom of the connecting frame 6 is slidably connected to the top of the deep hole drilling and boring machine 1. The machine also includes: The drill pipe centering and anti-winding component 7 is installed inside the retainer 5 and is used to effectively remove the shavings wrapped around the surface of the drill pipe; The drill pipe centering and anti-winding component 7 includes an inclined square column 71 slidably connected inside the retainer 5. One end of the inclined square column 71 is fixedly connected to a U-shaped plate 72. A drive shaft 73 is movably connected inside the U-shaped plate 72. A pressing roller 74 is mounted on the surface of the drive shaft 73. An inclined pusher 75 is located at the bottom right side of the retainer 5. The left side of the inclined pusher 75 is mounted on the right side of the drive shaft 73. A reciprocating scraping assembly 76 is located at the bottom of the inclined pusher 75. The reciprocating scraping assembly 76 includes positioning rods 761 located at the bottom of both sides of the inclined pusher 75. A removal toothed plate 762 is fixedly connected to the bottom of the positioning rods 761. A limiting sleeve 763 is installed at the bottom of the removal toothed plate 762. A Z-shaped sliding sleeve 763 is slidably connected inside the limiting sleeve 763. A Z-shaped square column 764 is slidably connected to the surface of a limiting sleeve 763. The left side of the Z-shaped square column 764 is installed on the right side of the U-shaped plate 72. An adjustment assembly 77 is installed inside the retainer 5. The adjustment assembly 77 includes an electric push rod 771 fixedly installed on the front and rear sides inside the retainer 5. The output end of the electric push rod 771 extends to the left side of the retainer 5 and is fixedly installed with a ring plate 772. The ring plate 772 is sleeved on the surface of the slide rod 4. An inclined plate 773 is fixedly installed on the right side of the ring plate 772. The surface of the inclined plate 773 contacts the surface of the inclined square column 71. A connecting block 774 is fixedly installed on the left side of the U-shaped plate 72 and the left side of the retainer 5. A tension spring 775 is fixedly installed on the surface of the connecting block 774.

[0021] Specifically, the deep hole drilling and boring equipment 1 is a commercially available horizontal CNC deep hole drilling and boring machine, which is the mainstream general-purpose processing equipment for precision machining of deep cavity and deep hole castings; the electric push rod 771 is a common industrial-grade linear reciprocating electric push rod, which is the power output component of the adjustment component 77, providing stable linear thrust for the radial feed and release of the clamping roller 74; the inclined square column 71 and the inclined plate 773 form a wedge block transmission pair, which converts the axial linear motion of the ring plate 772 into the radial feed motion of the U-shaped plate 72 and the clamping roller 74, which can ensure the synchronous action of multiple sets of clamping rollers 74 and improve the centering accuracy; the clamping roller 74 not only undertakes the core functions of radial support of the drill rod and suppression of chatter, but also recovers the rotational kinetic energy of the drill rod through friction, serving as the power input source for the entire linkage mechanism; the inclined push roller 75 is fixed in an inclined state. Mounted on the surface of the drive shaft 73, the inclined wheel surface undergoes periodic changes as it rotates with the drive shaft 73, equivalent to the transmission effect of the end face cam. This continuously pushes the positioning rod 761 and the removal toothed plate 762 below to perform axial reciprocating motion, driving the chip removal action to cycle. The removal toothed plate 762 scrapes off the strip-shaped chips wrapped around the drill rod surface by reciprocating scraping, preventing the chips from being carried into the guide and spindle parts with the drill rod. The Z-shaped square column 764 and the limiting sleeve 763 form a linear sliding guide pair, providing precise guidance and constraint for the reciprocating motion of the removal toothed plate 762, preventing swaying and jamming during the chip removal process. The tension spring 775 is a general-purpose cylindrical helical tension spring. When the electric push rod 771 retracts and the inclined plate 773 is unloaded, it pulls the U-shaped plate 72 and the inclined square column 71 to reset, causing the pressing roller 74 to automatically disengage from the drill rod surface.

[0022] like Figures 2 to 5 As shown, the cooling pressurized jet chip removal component 8 is installed on the right side of the U-shaped plate 72 to quickly remove chips from the inside of the workpiece cavity. The cooling pressurized jet chip removal component 8 includes a pressurized housing 81 fixedly installed on the right side of the U-shaped plate 72. The rear side of the pressurized housing 81 is connected to a liquid inlet pipe 82. A pressurized blade 83 is fixedly installed on the surface of the drive shaft 73. The pressurized blade 83 is located inside the pressurized housing 81. The right side of the pressurized housing 81 is connected to a jet conduit 84.

[0023] Specifically, the booster housing 81 is a commercially available centrifugal booster pump housing, serving as the supporting base for the cooling booster jet chip removal component 8. It provides a closed booster working chamber for the internal booster blades 83, and integrates inlet and outlet fluid channels to ensure the airtightness and flow stability of the cutting fluid delivery process. The booster blades 83 are fixedly mounted on the surface of the drive shaft 73 and are the core actuator for boosting the cutting fluid. They pressurize the cutting fluid in the chamber by rotating, and the output pressure is positively correlated with the rotational speed of the drive shaft 73, allowing for adaptive pressure control. It should be matched to the chip removal requirements under different processing parameters; the liquid inlet pipe 82 is a high-pressure flexible hose with flexible deformation capability. The input end is connected to the main cooling liquid supply pipeline of the deep hole drilling and boring equipment 1. When the inclined square column 71 drives the U-shaped plate 72 to perform radial feed, the liquid inlet pipe 82 can adapt to the radial displacement difference through its own flexible bending, and continuously supply atmospheric pressure cutting fluid to the pressurized housing 81; the spray conduit 84 can accurately deliver the pressurized high-pressure cutting fluid to the front end of the deep hole processing, ensuring that the chip removal power reaches the cutting area at the bottom of the hole directly.

[0024] like Figures 3 to 6 As shown, the jet-assisted chip removal component 9 is installed on the right side of the U-shaped plate 72 and is used to spray high-pressure air into the interior of the workpiece cavity to assist in the removal of chips. The jet-assisted chip removal component 9 includes an air storage housing 91 fixedly installed on the right side of the U-shaped plate 72. The air storage housing 91 is located in front of the pressurization housing 81. A fan blade 92 is fixedly installed on the surface of the drive shaft 73. The fan blade 92 is located inside the air storage housing 91. An air guide pipe 93 is connected to the right side of the air storage housing 91. An air curtain protective ring 94 is fixedly installed on the right side of the retainer 5. A telescopic pipe 95 is connected to the surface of the air guide pipe 93. The front end of the telescopic pipe 95 is connected to the air curtain protective ring 94.

[0025] Specifically, the air storage shell 91 serves as the mounting base for the jet-assisted chip removal component 9, forming a closed pressurized air chamber inside. It also integrates an air inlet and an air outlet, which can regulate the airflow direction and stabilize the output air pressure. The fan blade 92 is fixedly mounted on the surface of the drive shaft 73 and is the core actuator for generating high-pressure airflow. It completes air intake and pressurization when rotating synchronously with the drive shaft 73. The air guide pipe 93 is a general-purpose rigid air delivery pipe for industrial use, responsible for stably delivering the high-pressure airflow output from the air storage shell 91 to the deep hole machining position and the telescopic pipe 95 section. The telescopic pipe 95 is a corrugated telescopic air pipe with multi-directional bending capability. It can not only adaptively expand and contract with the axial displacement of the retainer 5, but also bend and compensate when the U-shaped plate 72 drives the air guide pipe 93 to move radially relative to the air curtain protection ring 94, thus preventing the pipeline from being pulled and damaged. The air curtain protection ring 94 is fixedly installed on the right side of the retainer 5. The right side is evenly distributed with nozzles, which can convert the input high-pressure airflow into a uniform air curtain around the nozzle, thus blocking the splashing of chips and cutting fluid.

[0026] like Figures 3 to 8As shown, a stabilizing plate 10 is fixedly installed on the surface of both the jet duct 84 and the air duct 93. The left side of the stabilizing plate 10 is fixedly installed on the right side of the U-shaped plate 72. An arc-shaped protective plate 11 is provided on the top of the inclined push wheel 75. The surface of the arc-shaped protective plate 11 is fixedly installed on the surface of the U-shaped plate 72. A limit block 12 is fixedly installed on the surface of the inclined plate 773. A reinforcing ring 13 is fixedly installed on the right side of the ring plate 772. The surface of the reinforcing ring 13 is fixedly connected to the surface of the inclined plate 773.

[0027] Specifically, the stabilizing plate 10 is a commonly used industrial pipe fixing support plate. It connects and fixes the injection conduit 84 and the air guide pipe 93 at multiple points, rigidly mounting the pipe to the side of the U-shaped plate 72. This effectively counteracts pipe vibration caused by processing vibration and fluid pulsation, prevents pipe joints from loosening and leaking, and ensures the stability of the liquid and gas transmission. The arc-shaped protective plate 11 is fixedly installed on the surface of the U-shaped plate 72 and covers the inclined pusher 75. It can prevent chips and atomized cutting fluid splashed during processing from falling into the transmission mating surface of the inclined pusher 75 and the positioning rod 761, avoiding chip jamming that could cause transmission failure and component wear, and extending the reciprocating cycle time. The scraping component 76 extends its service life; the limiting block 12 can rigidly block the radial sliding stroke of the inclined square column 71, precisely limiting the maximum feed of the clamping roller 74, preventing excessive feed from causing the roller to excessively press the drill rod, resulting in seizure or abnormal wear, and ensuring the safety and accuracy consistency of the centering adjustment; the reinforcing ring 13 is a general-purpose reinforcing ring component, fixedly connected to the connection between the ring plate 772 and the inclined plate 773, improving the bending resistance rigidity of the inclined plate 773, dispersing the local stress when the electric push rod 771 pushes, avoiding deformation of the inclined plate 773 under long-term stress, and ensuring the accuracy and structural reliability of the wedge block transmission.

[0028] like Figures 3 to 6 As shown, a filter sleeve 14 is fixedly installed on the left side of the surface of the gas storage housing 91. The air inlet of the gas storage housing 91 is located inside the filter sleeve 14. Buffer pads 15 are fixedly installed on the front and rear sides of the right side of the retainer 5. The buffer pads 15 are sleeved on the surface of the slide rod 4 and are located on the right side of the electric push rod 771.

[0029] Specifically, the filter sleeve 14 is an air intake dust filter that covers the outside of the air intake of the air storage housing 91. It can intercept and filter chips, dust and powder in the intake airflow, preventing hard impurities from entering the air storage housing 91 and hitting and wearing the fan blades 92, avoiding dynamic imbalance of the fan blades 92 and air passage blockage, and continuously maintaining a stable air supply to the jet auxiliary chip removal component 9. The buffer pad 15 is an industrial general-purpose columnar buffer and shock absorption kit that is fitted outside the slide rod 4 and arranged on the right side of the electric push rod 771. The buffer pad 15 bears the axial impact of the cage 5, absorbs sliding kinetic energy, weakens the vibration generated by rigid collision, reduces the fatigue wear of transmission parts such as the electric push rod 771, the inclined square column 71, and the inclined plate 773, and at the same time limits the rightward movement limit of the cage 5 to prevent over-travel adjustment.

[0030] The working principle and usage process of this invention are as follows: First, the deep cavity or deep hole casting to be processed is clamped and fixed on the workpiece support frame 3 and the tailstock of the deep hole drilling and boring equipment 1. The retainer 5 is adjusted to the corresponding position of the workpiece hole along the slide rod 4. The electric push rod 771 in the adjustment component 77 is started to push the ring plate 772 to the right along the slide rod 4. The U-shaped plate 72 is radially fed through the wedge block transmission of the inclined plate 773 and the inclined square column 71, so that the pressing roller 74 is in contact with the drill rod surface to complete the drill rod centering support. Subsequently, the deep hole drilling and boring equipment 1 drives the drill rod to rotate and feed for machining. The drill rod relies on friction to drive the clamping roller 74 and the transmission shaft 73 to rotate synchronously. On the one hand, the inclined pusher 75 drives the removal tooth plate 762 of the reciprocating scraping component 76 to move axially back and forth along the Z-shaped square column 764 to continuously scrape off the chips wrapped around the surface of the drill rod. On the other hand, it synchronously drives the booster blade 83 to rotate, which pressurizes the cutting fluid input by the inlet pipe 82 and then delivers it to the bottom of the deep hole through the spray pipe 84, carrying the chips and quickly discharging them. At the same time, the fan blade 92 rotates to generate a high-pressure airflow. The airflow is delivered to the air curtain protection ring 94 through the air guide pipe 93 and the telescopic pipe 95 and discharged. An annular air curtain is formed at the orifice to assist in chip removal and block the splashing of chips and cutting fluid. At the same time, the airflow blows from the air guide pipe 93 to the deep hole of the workpiece, which helps to push the chips in the hole to be discharged outward at an accelerated speed.

[0031] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
