Description

Technical Field

[0001] This utility model relates to the technical field of flap rudder processing equipment, and in particular to a device suitable for high-precision processing of the upper and lower end faces and inner holes of flap rudder hinge seats under conditions of large spacing and small space. Background Technology

[0002] As a key component in shipbuilding and aviation, the machining accuracy of the main rudder hinge seat directly affects the assembly quality and operational stability of the flap rudder. Among them, the roughness and parallelism of the upper and lower end faces of the hinge seat, as well as the concentricity of the inner holes of the upper and lower hinge seats, are core precision indicators. If these indicators do not meet the standards, it can easily lead to flap rudder jamming, accelerated wear, and even safety hazards.

[0003] In the existing technology, the processing of flap rudder hinge seats mostly relies on fixed models of milling machines. However, milling machines are limited by their processing range and space adaptability, and cannot meet the processing requirements of large-size flap rudders. Furthermore, it is difficult to achieve synchronous high-precision processing of the end face and inner hole in small space conditions. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of existing flap rudder hinge seat processing devices in large-spacing, small-space conditions, such as insufficient precision and poor adaptability. It provides a large-spacing, small-space flap rudder hinge seat processing device that achieves efficient and high-precision processing of the upper and lower end faces and inner holes of the hinge seat, while meeting the requirements of spatial adaptability.

[0005] To achieve the above technical objectives and requirements, the technical solution adopted by this utility model is as follows: a machining device for a large-spacing, small-space flap rudder hinge seat, comprising an inner hole machining fixture for machining the inner hole of the hinge seat and a turning end face device for machining the upper and lower end faces of the hinge seat; characterized in that: the inner hole machining fixture includes a platform, a guide rail, a reducer, a motor base, a universal joint, a connecting sleeve, a boring bar, a boring tool, and a self-aligning device; the platform is provided with a guide rail, and a slider is provided on the guide rail; the slider is fixedly connected to the motor base by bolts; the reducer is fixed on the motor base; a universal joint is provided at the output end of the reducer; the universal joint is connected to one end of the boring bar through the connecting sleeve; the boring bar is arranged in a horizontal direction; a boring tool is provided on the boring bar at the position corresponding to the inner hole of the flap rudder hinge seat to be machined; the other end of the boring bar passes through the inner hole of the flap rudder hinge seat to be machined in sequence and is then assembled and fixed with the self-aligning device; The turning end face device includes a slide seat, a pressure cap, a dial wheel, a screw, a bearing seat, a tool holder, a slide, and a flat washer. The pressure cap is provided on the slide seat and is fastened to the outer surface of the boring bar by screws. The slide is slidably mounted on the slide seat. One end of the screw passes through the slide seat and is limited by a locking nut, while the other end is rotatably connected to the bearing seat. The bearing seat and the slide seat are positioned by a tapered pin. The dial wheel is sleeved on the outside of the screw and is driven by a key. A one-way thrust bearing is provided between the bearing seat and the dial wheel. The flat washer is sleeved on the screw and located between the locking nut and the dial wheel. The tool holder is fixed to the slide by an internal hexagon head screw, and the tapered pin passes through the slide and the tool holder to achieve auxiliary positioning of the tool holder and the slide.

[0006] Preferably, the shaft retaining ring is set in the annular groove of the shaft section where the nut is fitted.

[0007] Preferably, the dial wheel has a wheel-shaped structure with multiple radial protrusions, and an inner hole in the center that mates with the screw. The inner hole is connected to the screw via a flat key. The outer edge of the wheel has protrusions evenly distributed for impact with the external positioning iron block, so as to drive the dial wheel to rotate around the screw axis, thereby driving the screw to rotate synchronously.

[0008] Preferably, the self-aligning device and the fixed fit between the boring bar can form an axial positioning constraint on the boring bar in the rotary turning state, so that the boring bar keeps the axis stable, ensuring that the inner holes of the hinge seats with an adjacent distance of more than 3 meters are turned into shape through the same process, and the machined inner holes meet the preset concentricity requirements.

[0009] Compared with the traditional structure, the beneficial effects of this utility model are: This utility model combines a turning end face machining device and an internal hole machining fixture, which can complete end face machining in a small space and adapt to large-spacing conditions where the distance between adjacent hinge seats is greater than 3 meters, thus solving the problem of "poor space adaptability" of existing fixtures.

[0010] During end face machining, the dial wheel impacts the iron block to drive the cutting tool to move precisely (0.25mm per revolution), ensuring the surface roughness and parallelism. During internal hole machining, the internal holes of adjacent hinge seats are machined simultaneously in the same process, and the self-aligning device compensates for coaxiality in real time, significantly reducing the concentricity error of the internal holes.

[0011] The pressure cover of the turning end face device is fixed to the boring bar with screws, which is convenient to disassemble and assemble, and can directly adjust the face to process the other end face; the internal hole processing does not require step positioning, reducing clamping errors and operation steps.

[0013] The present invention will be further described below.

[0014] See attached document Figure 1-5 A machining device for a large-spacing, small-space flap rudder hinge seat includes an inner hole machining fixture 1 for machining the inner hole of the hinge seat and a turning end face device 2 for machining the upper and lower end faces of the hinge seat; characterized in that: the inner hole machining fixture 1 includes a platform 11, a guide rail 12, a reducer 14, a motor base 15, a universal joint 16, a connecting sleeve 17, a boring bar 18, a boring tool 110, and a self-aligning device 19; the platform 11 is provided with the guide rail 12, and the guide rail 12 is provided with a slider 13, the... The slider 13 is fixedly connected to the motor base 15 by bolts. The reducer 14 is fixed on the motor base 15. The output end of the reducer 14 is provided with a universal joint 16. The universal joint 16 is connected to one end of the boring bar 18 through the connecting sleeve 17. The boring bar 18 is arranged in the horizontal direction. The boring bar 18 is provided with a boring tool 110 at the position corresponding to the inner hole of the hinge seat of the flap rudder to be processed. The other end of the boring bar 18 passes through the inner hole of the hinge seat of the flap rudder to be processed in sequence and is assembled and fixed with the self-aligning device 19. The turning end face device 2 is fixed to the outer circular surface of the boring bar 18 by a clamp. The turning end face device 2 includes a slide seat 22, a pressure cap 21, a dial wheel 25, a screw 28, a bearing seat 211, a tool holder 214, a slide 212, and a flat washer 26. The pressure cap 21 is provided on the slide seat 22 and is clamped to the outer circular surface of the boring bar 18 by a screw 23. The slide 212 is slidably disposed on the slide seat 22. One end of the screw 28 passes through the slide seat 22 and is limited by a nut 216, and the other end is rotatably connected to the bearing seat 211. The bearing seat 211 and the slide plate seat 22 are positioned by a tapered pin 24. The dial wheel 25 is sleeved on the outside of the screw 28. The dial wheel 25 and the screw 28 are driven by a flat key 29. A one-way thrust bearing 210 is provided between the bearing seat 211 and the dial wheel 25. The flat washer 26 is sleeved on the screw 28 and located between the locking nut 27 and the dial wheel 25. The tool holder 214 is fixed to the slide plate 212 by an internal hexagonal head screw 213. The tapered pin 24 passes through the slide plate 212 and the tool holder 214 to achieve auxiliary positioning of the tool holder 214 and the slide plate 212.

[0015] In this preferred embodiment, the shaft elastic retaining ring 215 is disposed in the annular groove of the shaft segment that is fitted with the nut 216.

[0016] In this preferred embodiment, the dial wheel 25 has a wheel-shaped structure with multiple radial protrusions and an inner hole in the center that mates with the screw 28. The inner hole is connected to the screw 28 via a flat key 29. The outer edge of the wheel has protrusions evenly distributed for impact with the external positioning iron block, so as to drive the dial wheel to rotate around the axis of the screw 28, thereby driving the screw 28 to rotate synchronously.

[0017] In this preferred embodiment, the fixed engagement between the self-aligning device 19 and the boring bar 18 can form an axial positioning constraint on the boring bar 18 in the rotary turning state, so that the boring bar 18 keeps the axis stable, ensuring that the inner holes of the hinge seats with an adjacent spacing of more than 3 meters are turned into shape through the same process, and the machined inner holes meet the preset concentricity requirements.

[0018] In specific implementation, the inner hole of the hinge seat is machined as follows: The flap rudder main rudder is fixed on the external frame, and the position of the self-aligning device 19 of the inner hole machining fixture 1 is adjusted so that the boring bar 18 passes through the inner hole of the adjacent hinge seat to be machined, and the boring tool 110 on the boring bar 18 is aligned with the inner hole to be machined surface; the drive motor is started, and the motor drives the boring bar 18 to rotate through the reducer 14, universal joint 16, and connecting sleeve 17. The boring bar 18 synchronously drives the boring tool 110 to rotate and cut the inner hole; at the same time, the motor seat 15 is pushed to move smoothly along the guide rail 12, so that the boring bar 18 drives the boring tool 110 to feed along the inner hole axis direction to ensure the inner hole machining depth; since the boring bar 18 passes through the adjacent hinge seat at the same time, and the self-aligning device 19 compensates for the coaxiality deviation of the boring bar 18 in real time, the inner holes of the adjacent hinge seats can be machined in the same process to ensure the concentricity of the inner holes.

[0019] Hinge seat end face machining: The pressure plate of the turning end face device 2 is tightened to the outer surface of the boring bar 18 of the inner hole machining fixture with screws, so that the turning tool on the tool holder 214 is aligned with the end face of the hinge seat to be machined; the external drive motor is started, and the boring bar 18 is driven to rotate through the reducer 14 and the universal joint 16. The boring bar 18 synchronously drives the dial wheel 25 of the turning end face device 2 to rotate; each time the dial wheel 25 rotates, the protrusion on its outer side will hit the externally fixed iron block, thereby driving the dial wheel 25 to rotate. 5. The screw 28 is rotated by the flat key 29. When the screw 28 rotates, the slide plate 212 is driven to slide along the slide plate seat 22 through the thread transmission. The slide plate 212 synchronously drives the tool holder 214 and the cutting tool to move. Each time the tool hits the iron block, the cutting tool moves a distance of 0.25mm. Repeat the above rotation and movement process until the end face of the hinge seat is machined to the preset size and roughness. Then turn off the motor, remove the end face turning device and adjust the surface. Repeat the operation to machine the end face of the other hinge seat.
