Description

Technical Field

[0002] Ship propellers are the core components of ship propulsion systems. Their design accuracy directly determines the ship's propulsion efficiency, navigation stability, and energy consumption. During the design and development of ship propellers, it is necessary to accurately measure various key dimensional parameters of the propellers (such as blade chord length, twist angle, blade surface curvature, edge thickness, etc.) to provide reliable data support for design optimization and subsequent processing and manufacturing.

[0003] Existing measurement methods for ship propeller design mostly employ traditional contact measuring tools, which have limited measurement dimensions and make it difficult to comprehensively measure the complex spatial curved surface profile of the propeller.

Moreover, the measurement process relies on manual operation, resulting in large human errors and low measurement efficiency, which is difficult to meet the measurement requirements of batch propeller design prototypes. Furthermore, most existing measurement structures cannot stably clamp and flexibly rotate the propeller, making the measurement operation at different angles and positions of the propeller cumbersome and further reducing measurement efficiency.

A data display screen 211 is provided on the left side of the data processor 210.

[0030] In this embodiment: by setting up a base 1, a measuring mechanism 2, a clamping and flipping mechanism 3, and a measuring support mechanism 4, the base 1 provides a supporting foundation for the measuring mechanism 2, the clamping and flipping mechanism 3, and the measuring support mechanism 4. The measuring mechanism 2 enables non-contact, precise measurement of ship propeller blades, effectively breaking through the dimensional limitations of traditional contact measuring tools. It can comprehensively cover the measurement needs of complex spatial curved surface contours of propeller blades, automatically complete the acquisition and processing of measurement data, and intuitively present the measurement data, greatly reducing reliance on manual operation, reducing human error, and significantly improving measurement efficiency. The clamping and flipping mechanism 3 can stably clamp the ship propeller blades and flexibly flip them, enabling measurements at different angles and positions without manual adjustment of the blade angle. This simplifies the measurement operation process, further improves measurement efficiency, and reduces the labor intensity of operators. The measuring support mechanism 4 provides a basic operating support platform for ship propeller blades during measurement work, and the support height can be flexibly adjusted according to measurement needs, thus providing convenience for basic simple measurement work and subsequent clamping and fixing of the propeller blades.

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, the clamping and flipping mechanism 3 includes a support plate 301, which is fixedly connected to the rear side of the top of the base 1. A stepper motor 302 is fixedly connected to the top of the rear side of the support plate 301. The output shaft of the stepper motor 302 passes through the support plate 301 and is fixedly connected to a U-shaped block 303. The surface of the output shaft of the stepper motor 302 is rotatably connected to the inner wall of the support plate 301 through a bearing.

[0032] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, clamping cylinders 304 are fixedly connected to both sides of the U-shaped block 303. The output rods of the two clamping cylinders 304 pass through the inner side of the U-shaped block 303 and are fixedly connected to the fixing clamping block 305. The first rubber pad 306 is fixedly connected to the opposite side of the two fixing clamping blocks 305.

[0033] Specifically, such as Figure 4 As shown, both sides of the U-shaped block 303 are provided with through holes 5 for use with the clamping cylinder 304, and the output rod surface of the clamping cylinder 304 is slidably connected to the inner wall of the through hole 5.

[0034] In this embodiment, by setting up a support plate 301, a stepper motor 302, a U-shaped block 303, a clamping cylinder 304, a fixing block 305, a first rubber pad 306, and a through hole 5, in use, the root of the ship propeller blade to be measured is placed inside the U-shaped block 303. Then, the clamping cylinders 304 on both sides of the U-shaped block 303 are activated, causing the output rods of the two clamping cylinders 304 to push the two fixing blocks 305 to move towards each other until the first rubber pads 306 of the two fixing blocks 305 are tightly attached to the surface of the propeller blade, thus stably clamping the propeller blade. Then, the stepper motor 302 can be activated, causing the output shaft of the stepper motor 302 to drive the U-shaped block 303 and the clamped propeller blade to rotate, realizing the adjustment of the propeller blade's flip angle. Measurements at different angles and positions can be achieved without manual adjustment of the propeller blade angle, simplifying the measurement operation process. The through hole 5 allows the output rod of the clamping cylinder 304 to pass through the U-shaped block 303 to achieve telescopic output.

[0035] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, the measuring support mechanism 4 includes a lifting cylinder 401. The bottom of the lifting cylinder 401 is fixedly connected to the top of the base 1. The output end of the lifting cylinder 401 is fixedly connected to a measuring support platform 402. The top of the measuring support platform 402 is fixedly connected to a second rubber pad 403.

[0036] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, auxiliary telescopic rods 404 are fixedly connected to the four corners of the bottom of the measuring support platform 402, and the bottom of the auxiliary telescopic rods 404 is fixedly connected to the top of the base 1.

[0037] In this embodiment: by setting up a lifting cylinder 401, a measuring support platform 402, a second rubber pad 403, and an auxiliary telescopic rod 404, the ship propeller to be tested can be placed on the measuring support platform 402 during use, so that the measuring support platform 402 provides a basic operating support platform for the ship propeller. The second rubber pad 403 can prevent the ship propeller from being damaged by rigid contact with the measuring support platform 402. Then, the lifting cylinder 401 can be activated, so that the output rod of the lifting cylinder 401 can extend or retract, thereby adjusting the height of the measuring support platform 402 and the propeller. This provides convenience for basic simple measurement work and subsequent clamping and fixing of the propeller. The auxiliary telescopic rod 404 can guide and limit the measuring support platform 401, so that the measuring support platform 401 can move up and down smoothly for adjustment.

[0038] Specifically, such as Figure 1 , Figure 2As shown, a controller 6 is provided on the rear side of the top left side of the base 1, which works in conjunction with the measuring mechanism 2, the clamping and flipping mechanism 3 and the measuring support mechanism 4. The controller 6 is electrically connected to the measuring mechanism 2, the clamping and flipping mechanism 3 and the measuring support mechanism 4.

[0039] Specifically, such as Figure 1 , Figure 2 As shown, a fixed bracket 7 is fixedly connected to the bottom of the controller 6, and the bottom of the fixed bracket 7 is fixedly connected to the rear side of the top left side of the base 1.

[0040] In this embodiment: the controller 6 can control the measuring mechanism 2, the clamping and flipping mechanism 3 and the measuring support mechanism 4 to work, and the controller 6 can be supported and fixed by the fixed bracket 7.

[0041] Specifically, such as Figure 1 , Figure 2 As shown, casters 8 are fixedly connected to the four corners of the bottom of the base 1, and the casters 8 have a brake locking pedal structure.

[0042] Specifically, such as Figure 1 , Figure 2 As shown, a push handle 9 is fixedly connected to the rear side of the top of the base 1, and an anti-slip handle cover 10 is fitted on the surface of the push handle 9.

[0043] In this embodiment: by setting the casters 8, the base 1 can be moved, thereby improving the flexibility of the device; by setting the push handle 9, the base 1 can be easily moved using the casters 8; by setting the anti-slip handle cover 10, the grip comfort of the push handle 9 can be improved and the anti-slip effect can be achieved.

[0044] Working Principle: In use, the ship propeller blade to be tested is first placed on the measuring support platform 402, providing a basic operating support platform for the blade. The second rubber pad 403 prevents damage caused by rigid contact between the blade and the platform. Then, the lifting cylinder 401 is activated via the controller 6, extending or retracting its output rod to adjust the height of the measuring support platform 402 and the blade. This facilitates basic simple measurement work and subsequent clamping and fixing of the blade. During the measurement phase, the measuring mechanism 2 can be activated via the controller 6, activating the Y-axis electric slide 2. 02 Slide along the Y-axis guide rail 201 on the top right of the base 1, driving the support frame 203 to move along the Y-axis. At the same time, the X-axis electric slide 205 slides along the X-axis guide rail 204 on the top inner side of the support frame 203, cooperating with the electric lifting rod 206 to drive the fixed plate 207 to move up and down, realizing the flexible movement of the laser displacement sensor 208 and angle sensor 209 in the three-dimensional space of X, Y, and Z. It can accurately align with different measurement parts of the blade. During the measurement process, if it is necessary to measure parameters of different angles of the blade, the blade root of the ship's blade on the measuring support platform 402 can be placed inside the U-shaped block 303, and then the controller 6 can start the two sides of the U-shaped block 303. The clamping cylinders 304 cause the output rods of the two clamping cylinders 304 to push the two fixed clamping blocks 305 to move towards each other until the first rubber pads 306 of the two fixed clamping blocks 305 are tightly attached to the surface of the blade, thus stably clamping the blade. After fixing, the lifting cylinder 401 can be activated by the controller 6 to drive the measuring support platform 402 to a height that does not hinder the blade rotation. Then, the stepper motor 302 can be activated by the controller 6, causing the output shaft of the stepper motor 302 to drive the U-shaped block 303 and the clamped blade to rotate, realizing the adjustment of the blade rotation angle. Measurements at different angles and positions can be achieved without manual adjustment of the blade angle, simplifying the measurement operation. In the measurement process, the laser displacement sensor 208 collects dimensional parameters such as the chord length, blade surface curvature, and edge thickness of the blade in real time, while the angle sensor 209 simultaneously collects the torsion angle parameters at different positions of the blade. The signals collected by both types of sensors are transmitted to the data processor 210 on the front side of the top of the support frame 203. After analyzing and processing the raw data, the data processor 210 displays the measurement results on the data display screen 211 in real time, which is convenient for operators to view and record intuitively. This achieves the effect of automatically completing the collection and processing of measurement data and intuitively presenting the measurement data, greatly reducing the reliance on manual operation, reducing human error, and significantly improving measurement efficiency.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
