Description

Technical Field

[0001] This invention relates to the field of launch tube processing technology, and in particular to a surface processing device for a composite material missile launch tube. Background Technology

[0002] Composite material missile launch tubes are core load-bearing components for missile storage, transportation, and launch. They are mostly made of carbon fiber / glass fiber reinforced resin matrix composites through winding molding, which has advantages such as high specific strength, light weight, corrosion resistance, high temperature resistance, and good insulation. They can significantly reduce the weight of the equipment, improve mobility and service life, and are the mainstream structural form of current missile launch equipment. After the launch tube is wound and molded, the outer diameter accuracy, surface roughness, and geometric tolerances are difficult to directly meet the assembly and use requirements. Milling is required to remove the molding allowance, correct roundness and straightness errors, and machine functional structures such as supports, lifting lugs, and mounting interfaces to ensure the fitting accuracy of the tube body with the guide rail, support, and launch system, ensuring smooth missile entry and exit from the tube, reliable positioning, and launch safety. During the surface milling process, milling machine tools are generally used for milling operations.

[0003] In the existing technology, the existing processing equipment requires manual fixing of the launching tube. For launching tubes of different specifications, each fixing requires precise fixing to ensure that the rotation axis is consistent with the axis of the launching tube. This is not only cumbersome, but also will cause the product to be scrapped if there is any inconsistency. In addition, the circumferential feed speed of the launching tube needs to be manually controlled to ensure good processing results. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art by proposing a surface processing device for composite material missile launch tubes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A composite material missile launch tube surface processing device includes a base, a support frame fixedly connected to the base, a platform slidably connected to the base, a plurality of support plates fixedly connected to the platform, a fixed cylinder fixedly connected to the support plates, a main cavity and a secondary cavity opened inside the fixed cylinder, and a cylinder fixing mechanism and a cylinder driving mechanism provided on the platform. The cylinder fixing mechanism includes a first tube, which is fixedly connected to a support plate. An air cylinder is fixedly connected to the first tube. The air cylinder is hollow. A rotating rod is rotatably connected to the air cylinder through a bearing. The rotating rod is hollow. Multiple sliding cylinders are fixedly connected to the side wall of the rotating rod. A sliding column is slidably connected to each sliding cylinder. A top block is fixedly connected to one end of the sliding column outside the sliding cylinder. The rotating rod and the fixed cylinder are rotatably connected through a bearing and extend into the secondary cavity. A third tube is fixedly connected to both the fixed cylinder and the air cylinder. The third tube connects the main cavity and the fixed cylinder. Multiple second tubes are fixedly connected to a section of the rotating rod inside the air cylinder. A pressure relief valve is installed inside the third tube.

[0006] Furthermore, the cylinder driving mechanism includes a drive shaft, which is rotatably connected to the fixed cylinder through a bearing. One end of the drive shaft extends through into the main cavity and is fixedly connected to multiple vortex blades. The other end of the drive shaft extends through into the secondary cavity and is fixedly connected to a rotating frame. Multiple fixed rods are fixedly connected to the inner sidewall of the rotating frame. Every two fixed rods form a group and are slidably connected to a slotted column. Multiple springs are fixedly connected between the slotted column and the rotating frame. A rotating block is fixedly connected to one end of the rotating rod located in the secondary cavity. The rotating block has multiple grooves, and the grooves correspond one-to-one with the slotted column. A fourth pipe is fixedly connected through the fixed cylinder, and the fourth pipe connects the main cavity to the outside.

[0007] Furthermore, a metal block is fixedly connected to the side wall of the rotating rod away from the fixed cylinder, and a permanent magnet is fixedly connected to the side wall of the upright frame.

[0008] Furthermore, the cross-section of the groove is semi-circular, the cross-section of the groove column is circular, and its radius is the same as the radius of the groove cross-section. The edges of the groove are all arc-shaped.

[0009] Furthermore, the inner sidewall of the slide cylinder is provided with multiple limiting grooves, and limiting blocks are slidably connected in the limiting grooves. The limiting blocks are fixedly connected to the sidewall of the slide column.

[0010] Furthermore, an X-axis motor is fixedly connected to the upper surface of the base via a bracket, and a third screw is fixedly connected to the output shaft of the X-axis motor, with the third screw threadedly connected to the platform.

[0011] Furthermore, a Y-axis motor is fixedly connected to the side wall of the upright frame via a bracket, and a first screw is fixedly connected to the output shaft of the Y-axis motor. A sliding seat is slidably connected to the upright frame, and the sliding seat is threadedly connected to the first screw. A Z-axis motor is fixedly connected to the sliding seat via a bracket, and a second screw is fixedly connected to the output shaft of the Z-axis motor. A milling machine is slidably connected to the side wall of the sliding seat, and the milling machine is threadedly connected to the second screw.

[0012] Furthermore, the sidewalls of the top block away from the rotating rod are all arc-shaped, and their surfaces are bonded with rubber pads.

[0013] Furthermore, the inclination angle of the vortex blade relative to the end face of the drive shaft is 28°-32°.

[0014] Furthermore, a vision probe is fixedly installed on the side wall of the rotating rod. The vision probe rotates synchronously with the rotating rod and collects the texture of the inner wall of the launch tube. The vision probe is electrically connected to the pressure relief valve through a PLC control circuit. The PLC control circuit is used to detect the slippage state of the tube and control the pressure relief valve to adjust the pressure and increase the clamping friction when slippage occurs.

[0015] The present invention has the following advantages: 1. Insert the launch tube to be processed into the rotating rod, and introduce compressed air through the first pipe. The compressed air entering the rotating rod will cause the sliding column to slide, thereby driving the top block to contact the inner wall of the launch tube and supporting and fixing it. No manual fixing is required, and the axis of the fixed launch tube remains aligned with the axis of the rotating rod. This makes it more convenient to use while ensuring processing accuracy. 2. After the support is fixed, as compressed air enters, the internal pressure increases continuously, which gradually increases the support fixing force until it reaches the opening value of the pressure relief valve. At this time, the compressed air enters the main cavity through the third pipe, impacting the vortex blades, which causes the drive shaft to rotate. The drive shaft then drives the rotating rod to rotate, thereby realizing the circumferential feeding of the launch tube. That is, after the fixing is completed, the circumferential feeding can be performed automatically without manual operation, which greatly improves the automation level of the device. 3. During the circumferential feed process, when the rotation speed is normal, the centrifugal force of the rotation cannot make the groove column leave the groove. At this time, the groove column normally drives the rotating block to rotate within the groove. However, if the rotation speed is too fast, the groove column will leave the groove under the action of centrifugal force, thus no longer driving the rotating block to rotate faster. When the rotation speed returns to the normal range, the groove column re-enters the groove and drives the rotating block. In this way, the circumferential feed speed can be controlled automatically and will not exceed a certain range, further ensuring the machining accuracy. 4. The present invention uses a vision detection unit that rotates synchronously with the drive mechanism to identify the relative slippage state in real time during processing without the need to set auxiliary marks or external sensors on the inner and outer walls of the cylinder. This will not damage the composite material matrix and is suitable for batch continuous processing of workpieces of various specifications. It has stronger versatility and environmental protection. 5. Through closed-loop adaptive control of the slippage signal and pressure regulating mechanism, the clamping force can be automatically increased to quickly eliminate slippage when it occurs, ensuring uniform and stable rotary feed, improving milling accuracy and surface quality, and avoiding deformation and damage to the cylinder caused by long-term high-pressure clamping. This improves processing stability, product qualification rate and automation level. Attached Figure Description

[0018] 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.

[0019] Example Reference Figure 1-6 A composite material missile launch tube surface processing device includes a base 1, a support frame 30 fixedly connected to the base 1, a platform 2 slidably connected to the base 1, a plurality of support plates 3 fixedly connected to the platform 2, a fixed cylinder 4 fixedly connected to the support plates 3, a main cavity 12 and a secondary cavity 13 opened inside the fixed cylinder 4, and a cylinder fixing mechanism and a cylinder driving mechanism are provided on the platform 2. The cylinder fixing mechanism includes a first pipe 5, which is connected to an external compressed air supply device. The first pipe 5 is fixedly connected to a support plate 3. An air cylinder 6 is fixedly connected through the first pipe 5. The air cylinder 6 is a hollow structure. A rotating rod 7 is rotatably connected through the air cylinder 6 via a bearing. The rotating rod 7 is a hollow structure. Multiple sliding cylinders 8 are fixedly connected through the side wall of the rotating rod 7. A sliding column 9 is slidably connected to the sliding cylinder 8. A top block 10 is fixedly connected to one end of the sliding column 9 located outside the sliding cylinder 8. The rotating rod 7 is rotatably connected to the fixed cylinder 4 via a bearing and extends into the secondary cavity 13. The fixed cylinder 4 and the air cylinder 6 are fixedly connected together by a third pipe 15. The third pipe 15 connects the main cavity 12 and the fixed cylinder 4. Multiple second pipes 11 are fixedly connected through the section of the rotating rod 7 located inside the air cylinder 6. A pressure relief valve 16 is installed inside the third pipe 15. The pressure relief valve 16 is a variable pressure relief valve. Its opening pressure threshold can be controlled by a PLC control circuit. This is existing technology and will not be described in detail here.

[0020] The cylinder drive mechanism includes a drive shaft 17, which is rotatably connected to the fixed cylinder 4 through a bearing. One end of the drive shaft 17 extends through into the main cavity 12 and is fixedly connected to multiple vortex blades 18. The other end of the drive shaft 17 extends through into the secondary cavity 13 and is fixedly connected to a rotating frame 19. Multiple fixed rods 22 are fixedly connected to the inner side wall of the rotating frame 19. Every two fixed rods 22 form a group and are slidably connected to a slotted column 23. Multiple springs 24 are fixedly connected between the slotted column 23 and the rotating frame 19. One end of the rotating rod 7 located in the secondary cavity 13 is fixedly connected to a rotating block 14. The rotating block 14 has multiple grooves 21, which correspond one-to-one with the slotted column 23. A fourth pipe 20 is fixedly connected through the fixed cylinder 4, which connects the main cavity 12 to the outside.

[0021] A metal block 27 is fixedly connected to the side wall of the rotating rod 7 away from the fixed cylinder 4, and a permanent magnet 28 is fixedly connected to the side wall of the upright frame 30. The magnetic attraction of the permanent magnet 28 to the metal block 27 provides certain support to the other end of the rotating rod 7, so as to avoid uneven force and bending.

[0022] The cross-section of the groove 21 is semi-circular, and the cross-section of the groove post 23 is circular, with the same radius as the cross-sectional radius of the groove 21. The edges of the groove 21 are all arc-shaped, which allows the groove post 23 to slide out of the groove 21 more smoothly and avoids jamming.

[0023] Multiple limiting grooves 25 are provided on the inner side wall of the slide cylinder 8. Limiting blocks 26 are slidably connected in the limiting grooves 25. The limiting blocks 26 are fixedly connected to the side wall of the slide column 9. Through the cooperation of the limiting grooves 25 and the limiting blocks 26, the slide column 9 is limited to prevent it from sliding out of the slide cylinder 8.

[0024] An X-axis motor 38 is fixedly connected to the upper surface of the base 1 via a bracket. The output shaft of the X-axis motor 38 is fixedly connected to a third screw 39, which is threadedly connected to the platform 2. A Y-axis motor 34 is fixedly connected to the side wall of the upright 30 via a bracket. The output shaft of the Y-axis motor 34 is fixedly connected to a first screw 35.

A Z-axis motor 36 is fixedly connected to the sliding seat 31 via a bracket. The output shaft of the Z-axis motor 36 is fixedly connected to a second screw 37. A milling machine 33 is slidably connected to the side wall of the sliding seat 31, and the milling machine 33 is threadedly connected to the second screw 37. The base 1 and platform 2, the upright 30 and sliding seat 31, and the sliding seat 31 and milling machine 33 are all slidably connected via slide rails (e.g.,...). Figure 2 (As shown).

[0025] The sidewalls of the top block 10 away from the rotating rod 7 are all curved, and rubber pads are glued to its surface. The curved surface can better fit the inner wall of the launch tube, and the rubber pads can increase friction and prevent slippage.

[0026] The vortex blade 18 has an inclination angle of 28°-32° relative to the end face of the drive shaft 17, and the vortex blade 18 has an inclination angle of 30° relative to the end face of the drive shaft 17. The vortex blade adopts a 30° inclination angle, which can maximize the utilization of high-pressure air kinetic energy, reasonably decompose the force to form a sufficient and stable rotational driving force, and easily overcome the inertia of the launch tube body to achieve smooth start and stop. The rotation speed is uniform and stable during operation, effectively avoiding the vibration and deviation phenomenon during milling, and greatly improving the machining accuracy of workpiece roundness and coaxiality. At the same time, the airflow is smoothly guided and does not easily generate turbulence interference. The balanced force distribution can reduce blade deformation loss. It can also take into account various working conditions such as rough milling heavy load and fine milling smooth machining. It is suitable for various milling operations of the tube body, with high overall drive efficiency, strong operation stability and better durability.

[0027] A vision probe 29 is fixedly installed on the side wall of the rotating rod 7. The vision probe 29 can take pictures of the inside of the launch tube before processing and continuously take pictures and compare them during processing. The vision probe 29 rotates synchronously with the rotating rod 7 and collects the texture of the inner wall of the launch tube. The vision probe 29 is electrically connected to the pressure relief valve 16 through the PLC control circuit. The PLC control circuit is used to detect the slippage state of the tube and control the pressure relief valve 16 to adjust the pressure and increase the clamping friction when slippage occurs.

[0028] In this invention, when the device is in operation, the composite material missile launch tube to be processed is first coaxially sleeved on the outside of the rotating rod 7, so that the inner wall of the tube corresponds to the position of the top block 10, completing the initial placement of the tube. An external compressed air source is connected through the first pipe 5. The compressed air enters the air cylinder 6 that is connected to it through the first pipe 5, and then enters the hollow structure of the rotating rod 7 through the second pipe 11 on the rotating rod 7. The air pressure is evenly applied to the inner end of each sliding column 9, pushing the sliding column 9 to slide outward along the sliding cylinder 8 in a sealed manner. The sliding column 9 drives the top block 10 at the end to expand outward synchronously until the arc-shaped surface of the outer side of the top block 10 is tightly pressed against the inner wall of the launch tube with the rubber pad. The uniform outward expansion of multiple sets of top blocks 10 realizes the automatic centering and coaxial fixation of the tube, ensuring that the axis of the tube is consistent with the axis of the rotating rod 7, and ensuring the processing reference accuracy without manual alignment.

[0029] After the top block 10 completes the cylinder body clamping and fixing, the first pipe 5 continuously supplies air, and the air pressure inside the air cylinder 6 and the rotating rod 7 continues to rise steadily. When the air pressure reaches the preset initial opening pressure of the pressure relief valve 16, the pressure relief valve 16 automatically opens, and the high-pressure gas flows into the main cavity 12 inside the fixed cylinder 4 through the third pipe 15, and impacts the vortex blades 18 at the end of the drive shaft 17 at high speed with directional airflow. The airflow impact force drives the vortex blades 18 to rotate stably around the axis, thereby driving the drive shaft 17 to rotate synchronously; the end of the drive shaft 17 that passes through the main cavity 12 and enters the secondary cavity 13 drives the rotating frame 19 to rotate, and the fixed side of the rotating frame 19... Rod 22 rotates synchronously with rotating frame 19. Slot column 23 remains in an inward contraction state under the tension of spring 24, and is stably engaged in the groove 21 on rotating block 14. Torque transmission is achieved through the meshing and limiting of slot column 23 and groove 21, which drives rotating block 14 and rotating rod 7 to rotate as a whole. Finally, the launching tube fixed by top block 10 moves in a uniform circular feed motion with rotating rod 7. In conjunction with the XYZ three-axis linkage motion of milling machine 33, the milling of the tube surface is completed. Excess gas in main cavity 12 can be stably discharged through fourth pipe 20 to maintain the air pressure balance inside main cavity 12 and ensure smooth driving process.

[0030] Throughout the milling process, the vision probe 29, which is fixedly installed on the side wall of the rotating rod 7, remains relatively stationary with the rotating rod 7 and rotates synchronously and coaxially with the rotating rod 7. The vision probe 29 acquires the natural texture image of the inner wall of the launch tube in real time at a fixed frequency and transmits the image signal to the matching PLC control circuit in real time. The PLC control circuit pre-stores the reference texture image of the inner wall in the initial state of processing and continuously performs pixel-level comparison and analysis between the real-time acquired image and the reference image during processing to calculate the texture position offset and similarity. When the cylinder experiences excessive milling resistance and slips relative to the rotating rod 7, a significant texture misalignment or offset will appear between the real-time image acquired by the vision probe 29 and the reference image. After identifying a texture difference exceeding the preset threshold, the PLC control circuit immediately determines that it is in a slipping state and quickly outputs an electrical signal to adjust the pressure relief valve 16, increasing the opening pressure threshold of the pressure relief valve 16. This reduces the exhaust volume of the third pipe 15, further increasing the air pressure inside the rotating rod 7 and the air cylinder 6. Consequently, the pressing friction force of the top block 10 against the inner wall of the cylinder increases significantly, thereby quickly counteracting the slipping trend and restoring the cylinder and rotating rod 7 to synchronous rotation, ensuring a uniform and stable circumferential feed speed. Once the slipping phenomenon is eliminated and the texture comparison returns to normal, the PLC control circuit controls the pressure relief valve 16 to gradually return to the initial set pressure, avoiding deformation, matrix cracking, or fiber layer damage to the thin-walled composite material cylinder caused by long-term high-pressure clamping.

[0031] Meanwhile, when the rotational speed of the rotating frame 19 exceeds the safe range driven by the airflow, the centrifugal force on the slot column 23 is greater than the tension of the spring 24. The slot column 23 slides outward along the fixed rod 22 and automatically disengages from the groove 21 on the rotating block 14, temporarily disconnecting the transmission between the rotating frame 19 and the rotating block 14. The rotational speed of the rotating rod 7 and the cylinder then automatically decreases. When the rotational speed returns to the safe range, the centrifugal force on the slot column 23 decreases, and under the tension of the spring 24, it re-enters the groove 21, restoring the transmission connection between the rotating frame 19 and the rotating block 14. This achieves automatic limiting and self-protection of the machining speed, further ensuring the milling machining accuracy and the stability of the device operation.

[0032] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
