Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for rudder blade spraying operations, specifically a steerable clamp for rudder blade spraying. Background Technology

[0002] Rudder blades are typically sheet-like structures installed at the stern or a specific location on equipment, controlling the direction of fluid flow or the direction of object movement by changing their angle or shape. They play a crucial role in transportation and weapon systems such as ships, aircraft, and missiles. Rudder blade painting fixtures are process equipment specifically designed for rudder blade painting, used to fix and support the blades to ensure stable positioning and uniform coating quality during the painting process. A rudder blade painting fixture typically consists of the following key parts: A fixing base: used to fix the entire fixture to the painting equipment, ensuring the fixture's stability. A positioning mechanism: including positioning rods and pins, used to precisely position the rudder blade, ensuring accurate positioning during the painting process. A clamping mechanism: such as grippers and pressure plates, used to clamp and fix the rudder blade, preventing movement or deformation during painting. Auxiliary components: such as turntables, baffles, and handles, to achieve more flexible painting methods and improve painting efficiency. These components can be selected according to specific painting requirements and the shape of the rudder blade. The fixture is simple and convenient to operate, and easy to install and disassemble. This helps improve work efficiency and reduce operational difficulty.

[0003] Chinese Patent Publication No. CN106425910B discloses a rudder blade tooling fixture, which includes a base, a sleeve, a telescopic rod, an upper seat, a cylinder, and a clamping device. One end of the sleeve is mounted on the base, and the other end of the sleeve is connected to one end of the telescopic rod. The other end of the telescopic rod is fixedly mounted to the lower surface of the upper seat, and the cylinder is mounted on the upper surface of the upper seat. The clamping device includes an output shaft, steel clamps A, B, C, and D, and a fastening nut. Steel clamps A, B, C, and D are sequentially mounted on the output shaft, and a fastening nut is installed between adjacent steel clamps at intervals. This invention redesigns a tooling fixture for clamping rudder blades based on some existing technologies, not only maintaining the advantages of the original technologies but also featuring convenient clamping, high clamping efficiency, and strong versatility.

[0004] The existing technical solutions mentioned above have the following drawbacks: they use clamps to clamp and fix rudder blades of a specific shape, which cannot meet the requirements for clamping operations of different sizes. At the same time, the rudder blades need to be sprayed at different angles during the spraying process, and the angle cannot be adjusted. Therefore, we propose a steerable clamp for rudder blade spraying to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a steerable fixture for rudder blade spraying, so as to solve the problem mentioned in the background art that the existing rudder blade fixtures can only perform the clamping and fixing operation of rudder blades of a specific shape by means of the fixture, which cannot meet the clamping operation of different sizes. At the same time, the spraying process requires spraying the rudder blades at different angles, but the angle cannot be adjusted.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steerable fixture for rudder blade spraying, comprising a base and a rudder blade, a rotating seat rotatably mounted above the base, two first lead screws symmetrically mounted above the rotating seat, a mounting seat drivingly mounted above the first lead screws, a fixture mechanism installed inside the mounting seat, the fixture mechanism comprising a Bernoulli suction cup mechanism, a second lead screw and a third lead screw, and a rudder blade adsorbed and connected to one side of the fixture mechanism.

[0007] A rotating seat groove is provided on the inner side of the upper end of the base. The lower end of the rotating seat extends into the interior of the rotating seat groove. The rotating seat and the rotating seat groove are rotatably connected by a bearing. A drive motor is fixedly installed at the middle position of the lower end of the base. The output end of the drive motor is connected to the rotating seat in a transmission manner.

[0008] Preferably, a second lead screw is symmetrically installed at both the front and rear ends of the inner side of the mounting base, and two third lead screws are driven and installed on one side of the second lead screw, with the third lead screws being arranged perpendicularly to the second lead screws.

[0009] Preferably, a Bernoulli suction cup mechanism is symmetrically installed at the upper and lower ends of one side of the second lead screw. The Bernoulli suction cup mechanism includes a mounting frame, a connecting rod, a suction cup base, a Bernoulli suction cup, an air inlet pipe, and a slider. The mounting frame has a cross structure and is fixedly connected to the slider. The slider is connected to the third lead screw via a transmission.

[0010] Preferably, a suction cup base is installed on one side of the mounting bracket, and connecting rods are fixedly installed between the suction cup base and the four corners of the mounting bracket, and the connecting rods are fixedly connected to the suction cup base.

[0011] Preferably, a Bernoulli suction cup is fixedly installed in the middle position inside the suction cup base, and an air inlet pipe is sealed to one side of the Bernoulli suction cup.

[0012] Preferably, the two mounting bases are mounted opposite each other, and the side end face of the rudder blade is in contact with the Bernoulli suction cup.

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

[0014] 1. In this invention, during clamping, one side of the rudder piece is first clamped. The second and third lead screws are adjusted to regulate the height and position of the four Bernoulli suction cup mechanisms, thus accommodating rudder pieces of different sizes. One end face of the rudder piece is brought close to the Bernoulli suction cup of one side of the clamping mechanism. Rapidly flowing air is output into the Bernoulli suction cup through the air inlet. When the airflow enters the suction cup through the air inlet, it accelerates due to the shape design of the Bernoulli suction cup and the setting of the air outlet. This accelerated flow causes a decrease in pressure inside the Bernoulli suction cup, thus creating a low-pressure area between the Bernoulli suction cup and the rudder piece. Due to the relatively high pressure of the surrounding air, this low-pressure area generates an inward suction force, pushing the rudder piece towards the low-pressure area and adhering it to the Bernoulli suction cup. The advantage of the Bernoulli suction cup lies in its non-contact working method, which reduces physical damage or contamination to the surface of the rudder piece and prevents the adhesion of undried paint. Furthermore, since the Bernoulli chuck does not require the rudder blade surface to be completely flat, it can work effectively even if the rudder blade surface has a certain degree of roughness or irregularity. In addition, the Bernoulli chuck does not need to form a seal with the rudder blade surface, so it can be used for rudder blades of various materials. This solves the problem that existing rudder blade clamps can only clamp and fix rudder blades of specific shapes, and cannot meet the needs of clamping operations of different sizes.

[0015] 2. When angle adjustment is required, the present invention starts the drive motor, and the output end of the drive motor drives the rotating seat to rotate, thereby adjusting the angle during spraying, thus meeting the spraying requirements of different angles of the rudder blade, and solving the problem that the existing rudder blade fixture cannot achieve angle adjustment when spraying different angles of the rudder blade during the spraying process.

Detailed Implementation

[0022] 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.

[0023] Please see Figure 1-5 One embodiment of this utility model is a steerable fixture for spraying rudder blades, comprising a base 1 and a rudder blade 7. A rotating seat 2 is rotatably mounted above the base 1. Two first lead screws 3 are symmetrically mounted above the rotating seat 2. A mounting seat 4 is driven above the first lead screws 3. A clamping mechanism 5 is installed inside the mounting seat 4. The clamping mechanism 5 includes a Bernoulli suction cup mechanism 6, a second lead screw 8, and a third lead screw 9. The rudder blade 7 is adsorbed and connected to one side of the clamping mechanism 5.

[0024] During clamping, one side of the rudder plate 7 is clamped first. The second lead screw 8 and the third lead screw 9 are adjusted to adjust the height and front-back position of the four Bernoulli suction cup mechanisms 6, thereby fitting the different sizes of the rudder plates 7. One end face of the rudder plate 7 is brought close to the Bernoulli suction cup 13 of the clamping mechanism 5. Rapidly flowing air is output into the Bernoulli suction cup 13 through the air inlet pipe 14. When the airflow enters the suction cup through the air inlet, the airflow will accelerate during the flow due to the shape design of the inside of the Bernoulli suction cup 13 and the setting of the air outlet. This accelerated flow causes the pressure inside the Bernoulli suction cup 13 to decrease, thereby forming a low-pressure area between the Bernoulli suction cup 13 and the rudder plate 7. Because of the higher ambient air pressure, this low-pressure area generates an inward suction force, pushing the rudder plate 7 towards the low-pressure area and adhering it to the Bernoulli suction cup 13. The advantage of the Bernoulli suction cup 13 lies in its non-contact operation, which reduces physical damage or contamination to the surface of the rudder plate 7 and prevents the adhesion of undried paint. Furthermore, since the Bernoulli suction cup does not require a perfectly flat surface for the rudder plate 7, it works effectively even if the surface has some roughness or irregularity. In addition, the Bernoulli suction cup 13 does not need to form a seal with the surface of the rudder plate 7, therefore it can be used with rudder plates 7 made of various materials.

[0025] Please see Figure 4The upper inner side of the base 1 is provided with a rotating seat groove 16, and the lower end of the rotating seat 2 extends into the interior of the rotating seat groove 16. The rotating seat 2 and the rotating seat groove 16 are rotatably connected by a bearing. A drive motor 15 is fixedly installed at the middle position of the lower end of the base 1, and the output end of the drive motor 15 is connected to the rotating seat 2 for transmission.

[0026] Please see Figure 1-2 The second lead screw 8 is symmetrically installed at the front and rear ends of the inner side of the mounting base 4. Two third lead screws 9 are installed on one side of the second lead screw 8, and the third lead screws 9 are arranged perpendicularly to the second lead screw 8.

[0027] Please see Figure 1-3 A Bernoulli suction cup mechanism 6 is symmetrically installed at both ends of one side of the second lead screw 8. The Bernoulli suction cup mechanism 6 includes a mounting frame 10, a connecting rod 11, a suction cup seat 12, a Bernoulli suction cup 13, an air intake pipe 14, and a slider 18. The mounting frame 10 has a cross structure and is fixedly connected to the slider 18. The slider 18 is connected to the third lead screw 9. A suction cup seat 12 is installed on one side of the mounting frame 10. A connecting rod 11 is fixedly installed between the suction cup seat 12 and the four corners of the mounting frame 10. The connecting rod 11 is fixedly connected to the suction cup seat 12. A Bernoulli suction cup 13 is fixedly installed in the middle position inside the suction cup seat 12. An air intake pipe 14 is sealed to one side of the Bernoulli suction cup 13. Two mounting seats 4 are installed opposite each other, and the side end face of the rudder plate 7 is in contact with the Bernoulli suction cup 13.

[0028] Working principle: During clamping, one side of the rudder plate 7 is clamped first. The second lead screw 8 and the third lead screw 9 are adjusted to adjust the height and front-back position of the four Bernoulli suction cup mechanisms 6, thereby fitting the different sizes of the rudder plates 7. One end face of the rudder plate 7 is brought close to the Bernoulli suction cup 13 of the clamping mechanism 5. Rapidly flowing air is output into the Bernoulli suction cup 13 through the air inlet pipe 14. When the airflow enters the suction cup through the air inlet, the airflow will accelerate during the flow due to the shape design of the inside of the Bernoulli suction cup 13 and the setting of the air outlet. This accelerated flow causes the pressure inside the Bernoulli suction cup 13 to decrease, thereby forming a low-pressure area between the Bernoulli suction cup 13 and the rudder plate 7. Because the surrounding air pressure is relatively high, this low-pressure area generates an inward suction force, pushing the rudder 7 towards the low-pressure area and adsorbing it onto the Bernoulli suction cup 13. At this time, the first lead screw 3 on this side drives the mounting base 4 to move left and right, thereby moving the rudder 7 closer to the spraying area. The drive motor 15 is started, and the output end of the drive motor 15 drives the rotating base 2 to rotate, thereby adjusting the spraying angle to meet the spraying requirements of the rudder 7 at different angles. After completing the spraying operation on one side, the two first lead screws 3 are driven to bring the two mounting bases 4 closer together, allowing the Bernoulli suction cup 13 of the clamping mechanism 5 on the other side to adsorb the other end of the rudder 7. Then, the Bernoulli suction cup 13 on the sprayed side is closed, and the first lead screw 3 on the sprayed side is driven again to separate the rudder 7 from the Bernoulli suction cup 13 on the sprayed side, and then the spraying operation on the other side is performed.
