Description

Technical Field

[0001] This utility model relates to the field of propeller blade grinding technology, specifically, to a multi-angle support suitable for propeller blade grinding. Background Technology

[0002] As a core component in shipbuilding, aviation, and other fields, the aerodynamic performance and surface finish of propeller blades are closely related. During manufacturing and maintenance, propeller blades typically require surface grinding. To reduce wobbling during grinding, several support frames are usually used to support and clamp the blades. However, due to the complex spatial curved surface structure of propeller blades and the significant differences in size and blade root angle among different propeller models, existing support frames often lack multi-degree-of-freedom adjustment capabilities, making it difficult to adapt to the curved surface angles and installation dimensions of different blade specifications. Multiple support frames are often required in combination for support and clamping, and the lack of connection between these frames leads to unstable clamping of the propeller blades. Under grinding stress, the propeller blades and support frames are prone to displacement, affecting the grinding accuracy of the grinding device. Furthermore, the adjustment process of multiple support frames is cumbersome, reducing work efficiency and impacting the overall grinding efficiency of the propeller blades. Therefore, we propose a multi-angle support suitable for propeller blade grinding. Summary of the Invention

[0003] The purpose of this invention is to provide a multi-angle support suitable for grinding propeller blades, so as to solve the problem of reduced grinding efficiency caused by reduced propeller blade support and clamping efficiency mentioned in the background art.

[0004] To address the aforementioned problems, the present invention aims to provide a multi-angle support for grinding propeller blades, comprising two base plates. A support mechanism is provided on the upper side of each base plate to support the propeller blade. The support mechanism includes a rotating component, a limiting component, and two positioning components disposed on the upper side of the base plates. The rotating component connects the limiting component and the positioning components to the base plates. The rotating component drives the limiting component to rotate, and the positioning components clamp and fix the limiting component. The limiting component clamps the propeller blade. Two connecting mechanisms are provided between the two base plates to connect them together.

[0005] As a further improvement to this technical solution, the rotating assembly includes an inverted U-shaped mounting bracket fixedly connected to the upper side of the base plate, and the top of the mounting bracket has two symmetrical mounting slots.

[0006] As a further improvement to this technical solution, the rotating assembly also includes a U-shaped rotating frame, the top of which is hinged to the inner wall of the mounting groove, and a first hydraulic rod is fixedly connected inside the rotating frame.

[0007] As a further improvement to this technical solution, the limiting component includes a rotating shell disposed above the mounting bracket, and the piston rod of the first hydraulic rod is hinged to the lower side of the rotating shell.

[0008] As a further improvement to this technical solution, two extension plates are symmetrically slidably connected on both sides inside the rotating shell. The ends of the two extension plates that are far apart from each other both penetrate the rotating shell and are rotatably connected to a limit block.

[0009] As a further improvement to this technical solution, the connecting mechanism includes a housing hinged to one side of one of the base plates, and a positioning bolt is threaded to the upper end of the housing away from the hinge.

[0010] As a further improvement to this technical solution, another base plate is hinged to a connecting plate on the side near the casing, and the end of the connecting plate away from the hinge is slidably connected to the inside of the casing.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This multi-angle support is suitable for grinding propeller blades. The operator adjusts the distance and angle between the two base plates and connects them together through a connecting mechanism. Then, the piston rod of the first hydraulic rod extends and retracts, causing the rotating shell to rotate so that its tilt angle matches the bottom of the propeller blade. The operator places the propeller blade on the upper side of the rotating shell. The piston rod of the second hydraulic rod retracts, causing the limiting block to move through the extension plate to clamp and fix the propeller blade. This allows for the quick fixation of propeller blades of different sizes and shapes, improving the support and clamping efficiency of the propeller blades and the overall grinding efficiency.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example. Please refer to the following: Figure 1 - Figure 6 As shown, the purpose of this embodiment is to provide a multi-angle support suitable for grinding propeller blades, including two base plates 1, with two connecting mechanisms 3 between them. The two connecting mechanisms 3 connect the two base plates 1 together. The connecting mechanisms 3 are telescopic structures, allowing the operator to adjust the distance and angle between the two base plates 1 by adjusting the length of the connecting mechanisms 3. A support mechanism 2 is provided on the upper side of the base plates 1 to support the propeller blades. The support mechanism 2 includes a rotating component, a limiting component, and two positioning components disposed on the upper side of the base plates 1. The rotating component connects the limiting component and the positioning components to the base plates 1. The rotating component is used to... The moving limit component rotates to adjust its tilt angle, aligning it with the tilt angle of the propeller blade's bottom. The positioning component clamps and fixes the limit component, preventing the rotating component from continuing to rotate after adjustment and ensuring that the rotating component supports the limit component. The operator transfers the propeller blade onto the limit component, which clamps the propeller blade. This allows the limit component to support and clamp propeller blades of different sizes and shapes, improving the support and clamping efficiency of the propeller blade and the stability of the grinding process. It also facilitates the grinding device's grinding treatment of the propeller blade's surface, thereby improving the grinding effect of the grinding device on the propeller blade.

[0016] refer to Figure 4The connecting mechanism 3 includes a housing 31 hinged to one side of one of the base plates 1. A positioning bolt is threaded onto the upper end of the housing 31 away from the hinge. A connecting plate 32 is hinged onto the side of the other base plate 1 near the housing 31. The end of the connecting plate 32 away from the hinge is slidably connected inside the housing 31. The operator can loosen the positioning bolt by turning it away from the connecting plate 32 with a wrench, thus releasing the fixation on the connecting plate 32. Limit bolts are threaded onto the hinge points of the housing 31 and connecting plate 32 with the base plate 1. The operator can loosen the limit bolts by turning them away from the hinge, thus releasing the fixation on the housing 31 and connecting plate 32. When the two base plates 1... When the distance between them changes, the connecting plate 32 slides inside the housing 31. During this process, the housing 31 and the connecting plate 32 rotate around the hinge point with the base plate 1. After the position of the base plate 1 is adjusted, the operator uses a wrench to tighten the positioning bolt, bringing it close to the connecting plate 32 and pressing it into the housing 31 to prevent the connecting plate 32 from sliding inside the housing 31. The operator also uses a wrench to tighten the limiting bolt, bringing it close to the hinge point to fix the position of the housing 31 and the connecting plate 32 to prevent the housing 31 and the connecting plate 32 from rotating around the hinge point with the base plate 1, ensuring that the distance between the two base plates 1 remains unchanged.

[0017] refer to Figure 5 The rotating assembly includes an inverted U-shaped mounting bracket 21 fixedly connected to the upper side of the base plate 1. Two mounting slots 211 are symmetrically opened on the top of the mounting bracket 21. The rotating assembly also includes a U-shaped rotating frame 212, the top of which is hinged to the inner wall of the mounting slots 211. A first hydraulic rod 213 is fixedly connected inside the rotating frame 212. A positioning assembly is used to press and fix the position of the rotating frame 212 to prevent it from rotating. A limiting assembly includes a rotating shell 22 disposed above the mounting bracket 21. The piston rod of the first hydraulic rod 213 is hinged to the lower side of the rotating shell 22. During extension and retraction, the piston rod of the first hydraulic rod 213 drives one side of the rotating shell 22 to move. When the two first hydraulic rods 21... When the piston rod of the first hydraulic rod 213 extends and retracts at different distances and in different directions, the piston rods of the two first hydraulic rods 213 cause the rotating shell 22 to move at different distances and in different directions, thereby causing the rotating shell 22 to tilt. This causes the rotating shell 22 to rotate around the hinge point with the piston rod of the first hydraulic rod 213, thereby adjusting the tilt angle of the rotating shell 22 and making the tilt angle of the rotating shell 22 match that of the bottom of the propeller blade. In addition, since the position of the hinge point between the piston rod of the two first hydraulic rods 213 and the rotating shell 22 changes, it causes the first hydraulic rod 213 and the rotating frame 212 to rotate around the hinge point with the mounting frame 21, changing the tilt angle of the first hydraulic rod 213 and the rotating frame 212, and ensuring that the rotating shell 22 rotates and adjusts normally. The positioning assembly includes an L-shaped positioning frame 23 fixedly connected to the bottom of the mounting bracket 21. The positioning frame 23 includes a vertical section and a horizontal section. Third hydraulic rods 231 are fixedly connected to both ends of the vertical section. The piston rods of the two third hydraulic rods 231 pass through the vertical section and are fixedly connected to positioning plates 232. An anti-slip pad is fixedly connected to the side of the positioning plate 232 near the rotating frame 212. The bottom of the rotating frame 212 is located between the vertical section and the positioning plate 232, and one side of the rotating frame 212 contacts the side of the vertical section near the positioning plate 232. During the extension and retraction process, the piston rod of the third hydraulic rod 231 drives the positioning plate 232 to move closer to or further away from the rotating frame 212. After the rotating shell 22 is adjusted, the piston rod of the third hydraulic rod 231 retracts and drives the positioning plate 232 to move closer to the rotating frame 212. During the movement, the positioning plate 232 presses the rotating frame 212 onto the positioning frame 23 to fix its position, preventing the rotating frame 212 from rotating and causing the tilt angle of the rotating shell 22 to change, and ensuring that the tilt angle of the rotating shell 22 is matched with that of the propeller blade. Two extension plates 221 are symmetrically slidably connected on both sides inside the rotating shell 22. The ends of the two extension plates 221 that are far apart from each other pass through the rotating shell 22 and are rotatably connected to a limiting block 222. To allow the extension plates 221 to move, a second hydraulic rod is fixedly installed inside the rotating shell 22. The piston rod of the second hydraulic rod is fixedly connected to the end of the extension plate 221 that is far away from the limiting block 222. During the extension and retraction process, the piston rod of the second hydraulic rod drives the extension plate 221 to move. During the propeller blade clamping process, the piston rod of the second hydraulic rod retracts and drives the limiting block 222 to move closer to the propeller blade through the extension plate 221. When the limiting block 222 contacts the side wall of the propeller blade, the propeller blade squeezes the limiting block 222 to rotate, so that the limiting block 222 and the side wall of the propeller blade adaptively fit together, thereby expanding the contact area between the limiting block 222 and the propeller blade and further improving the clamping effect of the limiting component on the propeller blade.

[0018] When using this device: During the propeller blade clamping process, the operator uses a wrench to tighten the positioning bolts and limit bolts to release the fixing of the housing 31 and the connecting plate 32. Then, the operator adjusts the distance and angle between the two base plates 1 according to the size of the propeller blade. During the movement of the base plate 1, the distance and angle between the two support mechanisms 2 change synchronously to make it suitable for propeller blades of different sizes and shapes. After the position of the base plate 1 is adjusted, the operator uses a wrench to tighten the positioning bolts and limit bolts to fix the position of the housing 31 and the connecting plate 32, ensuring that the distance between the two base plates 1 remains unchanged. The piston rods of the two first hydraulic rods 213 extend and retract, causing the rotating shell 22 to rotate, thereby changing the tilt angle of the rotating shell 22. During this process, the piston rods of the two second hydraulic rods extend and cause the two extension plates 221 to move away from each other, so that the distance between the two limiting blocks 222 is greater than the size of the propeller blade. After the angle of the rotating shell 22 is adjusted, the piston rod of the third hydraulic rod 231 retracts, causing the positioning plate 232 to move towards the rotating frame 212, so that the positioning plate 232 and the positioning frame 23 press and fix the bottom of the rotating frame 212, preventing the rotating frame 212 from rotating and causing the tilt angle of the rotating shell 22 to change. Subsequently, the staff placed the propeller blade on the upper side of the rotating shell 22, so that the lower side of the propeller blade contacted the upper side of the rotating shell 22, and the propeller blade was positioned between several limiting blocks 222. After the propeller blade was placed, the piston rod of the second hydraulic rod retracted and drove the limiting blocks 222 to move towards the propeller blade through the extension plate 221, so as to clamp and fix the propeller blade, improve the stability of the propeller blade during the grinding process, and facilitate the grinding device to grind the propeller blade.
