Description

Technical Field

[0001] This utility model relates to the field of auxiliary tooling technology for rudder compartment machining, specifically a flipping tooling for rudder compartment machining. Background Technology

[0002] The steering gear compartment, also known as the rudder compartment, is part of the stern structure and specifically refers to the compartment used to install the ship's steering gear equipment. The steering gear compartment is typically located below the upper deck at the stern. It is a crucial location for maneuvering the ship and controlling its course. Steering gear compartments are usually constructed of high-strength steel or other alloy materials to ensure the robustness and durability of the walls. These materials can withstand the various external forces and pressures that the ship may encounter during navigation. A steering gear compartment machining flipping fixture is a specialized tooling device designed specifically for flipping the steel during the machining process of the steering gear compartment. This flipping fixture can significantly improve machining efficiency and quality while reducing the labor intensity and safety risks for workers.

[0003] Chinese Patent Publication No. CN203600523U discloses a flipping fixture for flipping a workpiece and placing it on a conveying device. The flipping fixture includes: a rotating component rotatably disposed above the conveying device; and a connecting component disposed on the rotating component. The connecting component has a first state of engaging with the workpiece and a second state of driving the workpiece to flip around the axis of the rotating component. By applying this flipping fixture, the workpiece can be flipped from the first state to the second state on the fixture, eliminating the need for manual flipping and saving manpower.

[0004] The existing technical solutions described above have the following drawbacks: they rely on a motor to drive the rotating fixture, and when the motor switches between forward and reverse directions, it generates a reverse impact force on the motor rotor, causing additional mechanical stress on the motor. This stress causes motor vibration and noise, accelerates motor wear, and thus affects the motor's lifespan. High-frequency rotating operations shorten the motor's lifespan and increase equipment maintenance costs. Therefore, we propose a rotating fixture for rudder bay machining to address the aforementioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a flipping fixture for servo bay machining, addressing the problem described in the background art where existing servo bay steel plate flipping fixtures are driven by a motor. When the motor switches between forward and reverse directions, a reverse impact force is generated, causing additional mechanical stress on the motor. This stress causes motor vibration and noise, accelerates motor wear, and thus affects motor lifespan. High-frequency flipping operations result in a shorter motor lifespan, increasing equipment maintenance costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flipping fixture for machining a steering gear, comprising a flipping fixture fixing base, a support plate mounted on one side of the upper end of the flipping fixture fixing base, an mounting plate provided on one side of the support plate, a linear guide rail mounted above the support plate, a guide rail slider fixedly mounted on the other side of the upper end of the mounting plate, the guide rail slider being slidably connected to the mounting plate, a driving mechanism provided in the lower part of the mounting plate, a clamping mechanism fixedly mounted on one side of the driving mechanism, a sliding shaft provided on one side of the lower end of the driving mechanism, a linear groove opened inside the support plate, and a flipping groove opened at the middle position of the linear groove.

[0007] Preferably, the flip tool fixing seat and the support plate are fixedly connected by a mounting bracket.

[0008] Preferably, a clamping mechanism connecting plate is installed at one end of the clamping mechanism, a fixed clamping seat is fixedly installed at the upper end of one side of the clamping mechanism connecting plate, a sliding clamping seat mounting base is fixedly installed at the lower end of one side of the clamping mechanism connecting plate, movable clamping seat screws are symmetrically installed at both ends of the front side of the sliding clamping seat mounting base, and a movable clamping seat is installed at the front side of the sliding clamping seat mounting base.

[0009] Preferably, the fixed clamping seat and the movable clamping seat are correspondingly arranged. The outer end of the fixed clamping seat is provided with a fixed clamping seat housing, and the outer end of the movable clamping seat is provided with a movable clamping seat housing. Five first sliding grooves are equally spaced inside the fixed clamping seat housing and the movable clamping seat housing, and a first sliding block is slidably installed inside the first sliding groove.

[0010] Preferably, the first sliding block has a second sliding groove symmetrically formed inside, and a second sliding block is rotatably installed inside the second sliding groove. The second sliding block has a third sliding groove symmetrically formed inside, and a third sliding block is rotatably installed inside the third sliding groove. The third sliding groove has a fourth sliding groove symmetrically formed inside, and a fourth sliding block is rotatably installed inside the fourth sliding groove. Movable clamping seat sliders are symmetrically arranged on both sides of the movable clamping seat housing. The movable clamping seat sliders are connected to the movable clamping seat screw drive.

[0011] Preferably, the straight slide groove and the flip slide groove are connected, and the flip slide groove is a V-shaped groove.

[0012] Preferably, the driving mechanism includes a driving mechanism rotating seat, a fixed shaft, a transmission rod, a sliding shaft, and an anti-detachment cap. The driving mechanism rotating seat is rotatably connected to the mounting plate and fixedly connected to the clamping mechanism connecting plate. A fixed shaft is fixedly installed at the middle position of the driving mechanism rotating seat. A transmission rod is provided on one side of the driving mechanism rotating seat. A transmission rod is fixedly fitted on the outside of one side of the fixed shaft. A sliding shaft is fixedly installed at the center position of the lower end of the transmission rod. An anti-detachment cap is fixedly installed on the other side of the sliding shaft. The diameter of the anti-detachment cap is larger than the through diameter of the straight slide groove and the flip slide groove. The sliding shaft is slidably connected to the straight slide groove and the flip slide groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this invention, during flipping, a linear guide rail is driven, which in turn moves the guide rail slider backward. The guide rail slider then moves the mounting plate backward synchronously, allowing the sliding shaft to slide backward within the linear groove. When the sliding shaft reaches the flipping groove, because the curve length of the flipping groove is greater than the linear movement length, the drive mechanism's rotating seat continues to move backward synchronously with the guide rail slider. Meanwhile, the sliding shaft rotates downward around the fixed shaft until it reaches the center position of the flipping groove. As the sliding shaft slides, it drives the fixed shaft to rotate, thereby causing the clamping mechanism to rotate 90 degrees clockwise, continuing its movement. The sliding shaft moves upward along the arc of the rear side of the flipping groove, causing the fixed shaft to rotate 90 degrees clockwise. This, in turn, causes the clamping mechanism to rotate 90 degrees clockwise, making the flipping operation of the fixture simple and efficient. The position of the sliding shaft within the flipping groove can also be controlled according to the required machining angle, allowing for precise adjustment of the rotation angle. This solves the problem of existing servo bay steel plate flipping fixtures that rely on a motor for rotation. When the motor switches between forward and reverse directions, a reverse impact force is generated, causing additional mechanical stress on the motor. This stress causes motor vibration and noise, accelerates motor wear, and affects motor lifespan. High-frequency flipping operations result in a shorter motor lifespan and increased equipment maintenance costs.

[0015] 2. In this invention, during clamping, the steel plate processed for the rudder compartment is placed between the fixed clamping seat and the movable clamping seat. The movable clamping seat screw is driven, which drives the movable clamping seat with the movable clamping seat slider to move upward, thereby bringing it closer to the steel plate. The fourth sliding block first comes into contact with the steel plate. As the steel plate rotates within the fourth sliding groove due to its curvature, it simultaneously drives the third sliding block to rotate within the third sliding groove. As it moves, it drives the second sliding block to rotate within the second sliding groove. Subsequently, the first sliding block rotates within the first sliding groove, thereby fully allowing the fourth sliding block to come into contact with the surface of the steel plate. This satisfies the clamping operation of steel plates with forged shapes or curved curvatures due to the different usage requirements of different areas of the rudder compartment.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1-4An embodiment of this utility model provides a rotating fixture for machining a steering gear, comprising a rotating fixture fixing base 1, a support plate 3 mounted on one side of the upper end of the rotating fixture fixing base 1, an mounting plate 6 provided on one side of the support plate 3, a linear guide rail 4 mounted above the support plate 3, a guide rail slider 5 fixedly mounted on the other side of the upper end of the mounting plate 6, the guide rail slider 5 being slidably connected to the mounting plate 6, a driving mechanism 12 provided at the lower part inside the mounting plate 6, a clamping mechanism 7 fixedly mounted on one side of the driving mechanism 12, a sliding shaft 30 provided on one side of the lower end of the driving mechanism 12, a linear groove 25 opened inside the support plate 3, and a rotating groove 26 opened at the middle position of the linear groove 25.

[0023] During the flipping process, the linear guide 4 is driven, which in turn moves the guide slider 5 backward. The guide slider 5 then moves the mounting plate 6 backward in sync, allowing the sliding shaft 30 to slide backward within the linear groove 25. When the sliding shaft 30 slides into the flipping groove 26, because the curve length of the flipping groove 26 is greater than the linear movement length, the drive mechanism rotating seat 27 continues to move backward in sync with the guide slider 5. Meanwhile, the sliding shaft 30 rotates downward around the fixed shaft 28 until it reaches the center position of the flipping groove 26. The sliding of the movable shaft 30 drives the fixed shaft 28 to rotate, thereby causing the clamping mechanism 7 to rotate 90 degrees clockwise and continue to move backward. The sliding shaft 30 moves upward with the arc of the rear side of the flipping groove 26, thereby causing the fixed shaft 28 to continue to rotate 90 degrees clockwise, and causing the clamping mechanism 7 to rotate 90 degrees clockwise again. This makes the flipping operation of the flipping fixture simple and efficient. The position of the sliding shaft 30 in the flipping groove 26 can also be controlled according to the required processing angle, thereby achieving precise adjustment of the rotation angle.

[0024] Please see Figure 1 The flip tooling fixing seat 1 and the support plate 3 are fixedly connected by the mounting bracket 2.

[0025] Please see Figure 2A clamping mechanism connecting plate 13 is installed at one end of the clamping mechanism 7. A fixed clamping seat 8 is fixedly installed at the upper end of one side of the clamping mechanism connecting plate 13, and a sliding clamping seat mounting base 11 is fixedly installed at the lower end of one side of the clamping mechanism connecting plate 13. Movable clamping seat screws 10 are symmetrically installed at both ends of the front side of the sliding clamping seat mounting base 11, and a movable clamping seat 9 is installed at the front side of the sliding clamping seat mounting base 11. The fixed clamping seat 8 and the movable clamping seat 9 are correspondingly arranged. A fixed clamping seat housing 14 is provided at the outer end of the fixed clamping seat 8, and a movable clamping seat housing 23 is provided at the outer end of the movable clamping seat 9. Five first sliding grooves 15 are equally spaced inside the fixed clamping seat housing 14 and the movable clamping seat housing 23, and a first sliding block 16 is slidably installed inside the first sliding groove 15. The first sliding block 16 has a second sliding groove 17 symmetrically opened inside. The second sliding block 18 is rotatably installed inside the second sliding groove 17. The second sliding block 18 has a third sliding groove 19 symmetrically opened inside. The third sliding groove 19 has a third sliding block 20 symmetrically rotatably installed inside. The third sliding groove 19 has a fourth sliding groove 21 symmetrically opened inside. The fourth sliding groove 21 has a fourth sliding block 22 symmetrically rotatably installed inside. The movable clamping seat slider 24 is symmetrically arranged on both sides of the movable clamping seat housing 23. The movable clamping seat slider 24 is connected to the movable clamping seat screw 10 for transmission.

[0026] Please see Figure 3 The straight slide 25 and the tilting slide 26 are connected, and the tilting slide 26 is a V-shaped groove.

[0027] Please see Figure 1 and Figure 4 The drive mechanism 12 includes a drive mechanism rotating seat 27, a fixed shaft 28, a transmission rod 29, a sliding shaft 30, and an anti-detachment cap 31. The drive mechanism rotating seat 27 is rotatably connected to the mounting plate 6 and fixedly connected to the clamping mechanism connecting plate 13. The fixed shaft 28 is fixedly installed at the middle position of the drive mechanism rotating seat 27. The transmission rod 29 is provided on one side of the drive mechanism rotating seat 27. The transmission rod 29 is fixedly fitted on one side of the fixed shaft 28. The sliding shaft 30 is fixedly installed at the center position of the lower end of the transmission rod 29. The anti-detachment cap 31 is fixedly installed on the other side of the sliding shaft 30. The diameter of the anti-detachment cap 31 is larger than the through diameter of the straight slide groove 25 and the flip slide groove 26. The sliding shaft 30 is slidably connected to the straight slide groove 25 and the flip slide groove 26.

[0028] Working principle: In use, the steel plate processed for the rudder compartment is placed between the fixed clamping seat 8 and the movable clamping seat 9. The movable clamping seat screw 10 is driven, which drives the movable clamping seat 9, which is equipped with the movable clamping seat slider 24, to move upward, thus bringing it closer to the steel plate. The fourth sliding block 22 first comes into contact with the steel plate. As the curvature of the steel plate rotates inside the fourth sliding groove 21, it simultaneously drives the third sliding block 20 to rotate inside the third sliding groove 19. With this movement, the second sliding block 18 rotates inside the second sliding groove 17. Then, the first sliding block 16 rotates inside the first sliding groove 15, thus fully allowing the fourth sliding block 22 to come into contact with the surface of the steel plate. This satisfies the clamping operation of steel plates with forged shapes or curved curvatures due to the different usage requirements of different areas of the rudder compartment. When flipping, the linear guide rail 4 is driven, which drives the guide rail slider 5 to move backward. The guide rail slider 5 moves the mounting plate. 6. The sliding shaft 30 moves backward synchronously within the linear slide groove 25. When the sliding shaft 30 slides into the flip slide groove 26, since the curve length of the flip slide groove 26 is greater than the linear movement length, the drive mechanism rotating seat 27 continues to move backward synchronously with the guide rail slider 5. The sliding shaft 30 rotates downward around the fixed shaft 28 until it reaches the center position of the flip slide groove 26. As the sliding shaft 30 slides, it drives the fixed shaft 28 to rotate, thereby driving the clamping mechanism 7 to rotate 90 degrees clockwise and continue to move backward. The sliding shaft 30 moves upward along the arc of the rear side of the flip slide groove 26, thereby driving the fixed shaft 28 to continue to rotate 90 degrees clockwise, driving the clamping mechanism 7 to rotate 90 degrees clockwise again. This makes the flipping operation of the flipping fixture simple and efficient. The position of the sliding shaft 30 within the flip slide groove 26 can also be controlled according to the required processing angle, thereby achieving precise adjustment of the rotation angle.
