Description

Technical Field

[0001] The invention relates to the technical field of propeller grinding, and in particular to a grinding device for producing and assembling a propeller. Background Art

[0002] During the production and assembly process of propellers, the polishing step of propellers is very critical, as it directly affects the surface smoothness, hydrodynamic performance and service life of the propellers. When polishing propellers, due to their own weight and complex curved surface design, the polishing operation brings unique challenges.

[0003] To meet this challenge, special support and fixing devices are needed to ensure that the propeller is stably and reliably fixed during the grinding process to prevent damage and safety hazards caused by sliding and accidental flipping. In addition, propellers of different sizes require different flipping ranges when flipping, which requires the grinding equipment to have an automatic adjustment and shifting function. When the propeller flips, it automatically adjusts its position to avoid collision, ensuring the safety of the operation while also achieving an efficient and flexible grinding process.

[0004] Based on the above situation, the present invention proposes a polishing device for propeller production and assembly. Summary of the invention

Those of ordinary skill in the art will recognize that terms such as above, below, upward, downward, etc. are used to describe the drawings and do not represent limitations on the scope of the present invention as defined by the appended claims. Any numerical designations such as first or second are merely exemplary and are not intended to limit the scope of the present invention in any way.

[0030] Embodiment 1: A grinding device for producing and assembling a propeller, such as Figure 1-Figure 4 As shown, it includes a bracket 1, a placement frame 2, a slide 3, a nut 4, a rack 5, a slide 6, a first spring 601, a first spring 602, a guide frame 7, a pin 701, a slider 8, a rotating frame 9, a second spring 10, a slide bar 11, a grinder 12, a third spring 13, a motor 131, a gear 132 and a block 14. The upper part of the bracket 1 is rotatably connected to the placement frame 2, the vertical rod in the middle of the placement frame 2 is used to place the propeller, and two slides 3 are sleeved on the vertical rod in the middle of the placement frame 2. The two slides 3 are respectively located on the upper and lower sides of the propeller, and the nut 4 is threadedly connected to the vertical rod in the middle of the placement frame 2. The left and right parts of the top of the bracket 1 are both slidably connected to the rack 5, and the left and right parts of the top of the bracket 1 are both slidably connected to the slide 6. The front side of the rack 5 is fixedly connected to the first spring 601, and the upper rear side of the slide 6 is provided with a groove matching the first spring 601. The first spring 601 is connected between the slide 6 and the bracket 1. Spring 602, a guide frame 7 is rotatably connected between the left and right slides 6, a pin 701 is inserted in the middle of the slide 6, the pin 701 is inserted into the rear end of the guide frame 7, the guide frame 7 is tilted, a slider 8 is slidably connected to the middle of the guide frame 7, a rotating frame 9 is movably connected in the slider 8, a second spring 10 is sleeved on the rear end of the rotating frame 9, the second spring 10 is located between the slider 8 and the rotating frame 9, a slide rod 11 is slidably connected in the rotating frame 9, a grinder 12 is slidably connected to the rear of the slide rod 11, a third spring 13 is connected between the grinder 12 and the slide rod 11, a motor 131 is fixedly connected to the upper right part of the bracket 1, the output shaft of the motor 131 is fixedly connected to the right side of the placement frame 2, gears 132 are fixedly connected to the left and right sides of the placement frame 2, the gears 132 are meshed with adjacent racks 5, a left-right symmetrical card block 14 is fixedly connected to the front of the rotating frame 9, and a circle of card grooves 15 adapted to the card block 14 is opened on the front side of the slider 8

[0031] When using the device, the staff removes the nut 4 and the upper slide cylinder 3 from the vertical rod of the placement frame 2, and then puts the propeller on the vertical rod of the placement frame 2. After the propeller is placed, the staff resets the nut 4 and the upper slide cylinder 3, fixes the propeller on the vertical rod through the nut 4, and then pulls the rotating frame 9 to slide forward in the slider 8. The second spring 10 is deformed, and the rotating frame 9 slides forward and controls the block 14 to separate from the slot 15. At this time, the staff can control the rotating frame 9 to rotate. The rotation of the rotating frame 9 drives the slide rod 11 and the grinder 12 to rotate, and then adjusts the angle of the grinder 12 so that the grinding disc of the grinder 12 adapts to the inclination angle of the propeller blade. After the angle adjustment of the grinder 12 is completed, the staff no longer pulls the rotating frame 9 forward. Under the action of the second spring 10 returning to its original position, the rotating frame 9 slides backwards to control the card block 14 to fit into the card slot 15, thereby fixing the rotating frame 9 to fix the angle of the grinder 12. At this time, the staff presses the grinder 12 to slide downwards, and the third spring 13 is deformed, so that the grinder 12 slides downwards and contacts the propeller blades, and then pushes the slide bar 11 to slide backwards in the rotating frame 9 to control the grinder 12 to grind from front to back along the propeller blades. After grinding one blade, the staff releases the grinder 12 and the slide bar 11. Under the action of the third spring 13 returning to its original position, the grinder 12 slides upwards to return to its original position and separates from the blades. Moreover, since the guide frame 7 is arranged to be inclined, when the staff releases the slide bar 11, the slide bar 11 will automatically drive the grinder 12 on the rotating frame 9. The staff member pushes the propeller to rotate 90 degrees clockwise, and then rotates the next blade to the grinder 12. Then the above action is repeated to grind the next blade. When the upper sides of the four blades are polished, the staff member drives the placement rack 2 to flip 180 degrees through the motor 131. The flipping of the placement rack 2 drives the propeller to flip and change the surface. Under the action of the slide cylinder 3 and the nut 4, the propeller can be stably fixed on the vertical rod of the placement rack 2. When the placement rack 2 flips, it drives the gear 132 to rotate. The rotation of the gear 132 drives the rack 5 to slide forward. The rack 5 slides forward and drives the first spring piece 601 to move forward. The first spring piece 601 moves forward and pushes the slide 6 forward through the groove. The first spring 602 is deformed, and the slide 6 slides forward, driving the guide frame 7, the slider 8, the rotating frame 9, the slide rod 11 and the grinder 12 to move forward. After the grinder 12 moves forward, it moves away from the propeller so that the propeller can turn over and avoid collision. After the slide 6 slides forward to the limit distance, the first spring piece 601 continues to move forward and will be squeezed and deformed upward by the slide 6, and then no longer pushes the slide 6 forward. At this time, under the action of the first spring 602 being reset, the slide 6 slides backward and resets accordingly. The slide 6 slides backward, driving the guide frame 7, the slider 8, the rotating frame 9, the slide rod 11 and the grinder 12 to move backward and reset, so as to grind the other side of the propeller blade. When the grinding of both sides of the propeller is completed, the staff pulls out the pin 701.After the pin 701 is pulled out, the rear end of the guide frame 7 is no longer fixed. At this time, under the action of gravity, the guide frame 7 drives the slider 8, the rotating frame 9, the slide bar 11 and the grinder 12 to rotate downward, so that the staff can perform subsequent balance tests. After the test is completed, the staff drives the placement frame 2 to reverse through the motor 131, and then drives the propeller to reverse and reset.

[0032] Embodiment 2: Based on embodiment 1, Figure 1 and Figure 5 As shown, it also includes a fixed plate 16 and a telescopic rod 17. The upper and lower slide cylinders 3 are fixedly connected to the fixed plate 16 on one side close to the propeller. The fixed plate 16 is fixedly connected to the one side close to the propeller with four circumferentially equidistantly distributed telescopic rods 17. The telescopic rods 17 extend and retract by their own gravity.

[0033] When the device is used, the telescopic rod 17 located at the lower side of the propeller is in a retracted state under the action of its own gravity, while the telescopic rod 17 on the upper side is in an extended state. The four extended telescopic rods 17 are respectively clamped on the higher side of the propeller blade. When grinding, the contact between the grinder 12 and the blade will apply a counterclockwise force to the blade, and the extended telescopic rod 17 on the upper side can clamp the blade and prevent the blade from rotating counterclockwise for grinding. When the propeller flips over, the telescopic rods 17 on the upper and lower sides will also flip and change positions. At this time, the telescopic rod 17 on the upper side will be extended, and the telescopic rod 17 on the lower side will be shortened to ensure that the higher side of the blade is always clamped to prevent the propeller from rotating counterclockwise.

[0034] like Figure 1 and Figure 6 As shown, it also includes a block 18, a guide frame 19, an electromagnet 20 and a magnet 21. The left and right parts of the top of the bracket 1 are slidably connected to the two blocks 18. The rear side of the lower end of the block 18 is an arc structure for extrusion cooperation with the rack 5. The left and right parts of the upper side of the bracket 1 are slidably connected to the guide frame 19. The front and rear parts of the guide frame 19 are both provided with oblique grooves. The block 18 is slidably connected to the adjacent guide frame 19 through the oblique grooves. The left and right parts of the upper side of the bracket 1 are fixedly connected to the electromagnet 20, and the front side of the guide frame 19 is fixedly connected to the magnet 21.

[0035] When using the device, the placement rack 2 is flipped to drive the gear 132 to rotate and control the rack 5 to slide forward, the rack 5 will contact the block 18, and then squeeze the block 18 to slide upward. When the rack 5 moves forward and separates from the block 18, under the action of the block 18's own gravity, the block 18 slides downward and resets, and then blocks behind the rack 5, restricting the rack 5 from sliding backward. The placement rack 2 is locked by the engagement of the rack 5 and the gear 132, further improving the stability of the propeller support after flipping. When the propeller is polished, the staff controls the electromagnet 20 to be energized, and the electromagnet 20 is energized to attract the magnetic block 21 to move forward. The magnetic block 21 moves forward and drives the guide frame 19 to slide forward. The guide frame 19 slides forward and squeezes the block 18 through the inclined slot to slide upward. After the block 18 slides upward, it no longer blocks the rack 5. At this time, the placement rack 2 can be flipped and reset.

[0036] like Figure 7 and Figure 8 As shown, it also includes a second spring piece 22, a baffle 221, a tension spring 23, a magnetic frame 24 and a magnetic ring 25. The rear part of the slide rod 11 is slidably connected to the left and right symmetrical second spring piece 22, the upper part of the grinder 12 is fixedly connected to the baffle 221, the upper part of the second spring piece 22 is a bending structure inclined outward, the baffle 221 is squeezed and matched with the second spring piece 22, a tension spring 23 is connected between the second spring piece 22 and the slide rod 11, the rear part of the slide rod 11 is slidably connected to the magnetic frame 24, the rear side of the rotating frame 9 is fixedly connected to the magnetic ring 25, and the magnetic ring 25 and the magnetic frame 24 are adsorbed on each other.

[0037] In the initial state, the magnetic frame 24 and the magnetic ring 25 are attracted to each other, the magnetic frame 24 is in a state of squeezing the second spring piece 22 forward, and the tension spring 23 is in a deformed state. When the slide bar 11 drives the grinder 12 to move backward, the magnetic frame 24 will also move backward and separate from the magnetic ring 25. At this time, under the action of the resetting of the tension spring 23, the left and right second spring pieces 22 slide toward each other, thereby squeezing the magnetic frame 24 to slide backward. When the staff presses the grinder 12 to slide downward and contact the propeller blade, the baffle 221 will also move downward with the grinder 12, thereby passing through the second spring piece 22 The blocking piece 221 is stuck to limit the position of the grinder 12. There is no need for the staff to press the grinder 12 all the time, which is more labor-saving to use. After grinding, the slide bar 11 drives the grinder 12 to move forward, and the magnetic frame 24 and the second spring piece 22 move forward accordingly. When the magnetic frame 24 moves forward until it is adsorbed on the magnetic ring 25, the magnetic frame 24 will slide forward on the slide bar 11, and then squeeze the left and right second spring pieces 22 to slide back to back and open, and the tension spring 23 is deformed. After the second spring piece 22 slides back to back and opens, it no longer blocks the blocking piece 221, and the grinder 12 can slide upward to reset.

Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention.
