Description

Technical Field

[0001] This utility model relates to the field of ship rudder keyway machining technology, specifically to a portable high-precision ship rudder keyway machining device. Background Technology

[0002] The keyway is an important component of the rudder, used to install and fix the rudder stock or other transmission components. Through the cooperation of the keyway and the key, the accurate positioning and stable transmission of the rudder stock in the rudder can be ensured, thereby realizing the steering control of the ship.

[0003] Patent document CN216502569U discloses a keyway machining device for a ship's rudder post hole. The device includes a machine tool, two guide rods fixedly mounted on both sides of the machine tool's inner wall, with both ends of the outer wall of each guide rod fixedly connected to the inner wall of the machine tool. A lead screw is inserted through the middle of the inner wall of the machine tool, with both ends rotatably connected to the two sides of the inner wall of the machine tool. Sliding blocks are fitted onto the outer walls of the two guide rods, with the middle of the sliding blocks inserted through the outer wall of the lead screw, and the outer wall of the lead screw threadedly connected to the inner wall of the sliding blocks. A motor is fixedly mounted at the bottom of each lifting rod, and a spindle is rotatably mounted at the output end of the motor. The guide rods provide stability to the sliding blocks, and the inner wall of the sliding blocks is threadedly connected to the lead screw. When the lead screw rotates, it forms a helical drive with the sliding blocks. The rotation of the milling cutter, combined with the left and right movement of the sliding blocks, enables the device to perform keyway machining on the rudder post hole.

[0004] The device can eliminate the problem of iron filings getting tangled in the milling cutter and workpiece when it is working by spraying water from the nozzle. However, the iron filings sprayed from the nozzle will fall onto the machine tool or other places, requiring the staff to process and clean them up. In addition, the water sprayed during processing will also spread everywhere, making the processing environment humid. Utility Model Content

[0005] To address the aforementioned issues, a portable, high-precision rudder keyway machining device is provided. Utilizing a nozzle in conjunction with a water pump, it removes iron filings from the milling cutter and workpiece surface. These iron filings and wastewater fall into the interior of the frame and onto the side walls of the baffle. Simultaneously, a moving plate drives a cleaning brush to further clean the iron filings from the frame and baffle side walls, causing them to fall through a through-hole at the bottom of the frame into the housing. An internal filter plate filters the iron filings, and the filtered water is collected inside the housing for reuse. This method avoids spillage of iron filings and wastewater, preventing environmental impact, and conserves water resources.

[0006] To address the problems of existing technologies, this utility model provides a portable high-precision rudder keyway machining device, comprising a housing, a water pump and a frame respectively arranged on the top of the housing, baffles arranged on both outer walls of the frame, a movable plate movably arranged inside the frame, a plurality of connecting rods arranged on the top of the movable plate, a sliding plate arranged on the top of the connecting rods, a support plate slidably arranged on the outside of the connecting rods, a motor arranged on the top of the support plate, a milling cutter arranged on the output shaft of the motor, and cleaning brushes arranged on both outer sides of the movable plate, the bottom of the cleaning brush abutting against the inside of the frame, and the side wall of the cleaning brush abutting against the side wall of the baffle.

[0007] Preferably, the bottom of the frame has several through holes for dropping iron filings and wastewater, and the top of the box has a notch that communicates with the through holes.

[0008] Preferably, the frame has a connecting plate inside, the bottom of the connecting plate has symmetrical electromagnetic slide rails, and the top of the slide plate has an electromagnetic slider that is slidably connected to the electromagnetic slide rails.

[0009] Preferably, the top of the movable plate is provided with an electric push rod, the movable end of which is connected to the bottom of the support plate. The top of the movable plate is also provided with symmetrical telescopic rods, the telescopic ends of which are connected to the bottom of the support plate.

[0010] Preferably, a nozzle is provided above the motor, one end of the nozzle is connected to a water supply pipe, the other end of the water supply pipe is connected to the output end of the water pump, and the input end of the water pump is connected to the inside of the housing through a pipe.

[0011] Preferably, a filter plate for filtering iron filings is slidably disposed inside the housing.

[0012] The advantages of this utility model compared to the prior art are:

[0013] The electromagnetic slider, in conjunction with the electromagnetic rail, moves the sliding plate, which in turn moves the support plate and the moving plate. This allows the milling cutter to machine the rudder at different positions. Then, an electric push rod is used to adjust the positions of the support plate, motor, and milling cutter, enabling the machining of rudders at different heights. Simultaneously, a spray nozzle, in conjunction with a water pump, removes iron filings from the milling cutter and workpiece surface. These iron filings and wastewater fall into the interior of the frame and onto the side walls of the baffle. As the moving plate moves, it drives a cleaning brush to clean the iron filings from the frame and baffle side walls, causing them to fall through a through-hole at the bottom of the frame into the housing. An internal filter plate filters the iron filings, and the filtered water is collected inside the housing for reuse. This prevents iron filings and wastewater from spilling everywhere and affecting the working environment, while also conserving water resources. Attached Figure Description

[0021] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0022] like Figures 1 to 6 As shown, this utility model provides:

[0023] A portable high-precision rudder keyway machining device includes a housing 1. A water pump 2 and a frame 4 are respectively installed on the top of the housing 1. Baffles 6 are installed on both outer walls of the frame 4. A movable plate 9 is movably installed inside the frame 4. Several connecting rods 10 are installed on the top of the movable plate 9. A sliding plate 13 is installed on the top of the connecting rods 10. A support plate 12 is slidably installed on the outside of the connecting rods 10. A motor 11 is installed on the top of the support plate 12. A milling cutter 16 is installed on the output shaft of the motor 11. Cleaning brushes 8 are installed on both outer sides of the movable plate 9. The bottom of the cleaning brushes 8 abuts against the inside of the frame 4, and the side wall of the cleaning brushes 8 abuts against the side wall of the baffles 6.

[0024] Through the spraying action of nozzle 15, combined with the continuous operation of water pump 2, iron filings generated by milling cutter 16 during processing and iron filings on the surface of workpieces can be effectively removed. These removed iron filings and wastewater fall into the internal space of frame 4 and onto the side walls of baffle 6. The cleaning brush 8 moves synchronously using moving plate 9. The cleaning brush 8 thoroughly cleans the iron filings inside frame 4 and on the side walls of baffle 6. These removed iron filings fall into the interior of housing 1 through the through-hole at the bottom of frame 4. Housing 1 is equipped with a dedicated filter plate 7, whose main function is to effectively filter the fallen iron filings. The filtered water is collected inside housing 1, which not only prevents iron filings and wastewater from spilling everywhere and affecting the cleanliness of the working environment, but also achieves water resource recycling, thereby conserving water resources.

[0025] like Figure 5 and Figure 6 As shown, the bottom of the frame 4 has several through holes for dropping iron filings and wastewater, and the top of the box 1 has a notch that connects to the through holes.

[0026] By utilizing the through holes at the bottom of frame 4 and the notch at the top of housing 1, the generated iron filings wastewater can be easily guided and collected inside housing 1. This makes wastewater treatment more efficient and convenient, ensuring a clean working environment and the normal operation of the equipment.

[0027] like Figure 4 and Figure 5 As shown, a connecting plate 5 is provided inside the frame 4, and symmetrical electromagnetic slide rails 19 are provided at the bottom of the connecting plate 5. An electromagnetic slider 14 that is slidably connected to the electromagnetic slide rails 19 is provided at the top of the slide plate 13.

[0028] The smooth movement of the slide plate 13 is achieved through the precise cooperation between the electromagnetic slider 14 and the electromagnetic rail 19. This movement mechanism further drives the support plate 12 and the moving plate 9 to move along a predetermined path. This design allows the milling cutter 16 to flexibly and precisely machine the rudder in different positions. Through this efficient transmission system, the milling cutter 16 can remain stable during machining, thereby improving machining accuracy and efficiency.

[0029] like Figure 4 As shown, an electric push rod 18 is provided on the top of the movable plate 9. The movable end of the electric push rod 18 is connected to the bottom of the support plate 12. A symmetrical telescopic rod 17 is also provided on the top of the movable plate 9. The telescopic end of the telescopic rod 17 is connected to the bottom of the support plate 12.

[0030] The electric push rod 18, driven by its power, moves the support plate 12, the motor 11, and the milling cutter 16 precisely. This design allows the equipment to flexibly and precisely machine and grind ship rudders at different heights. Meanwhile, the telescopic rod 17 ensures the stability of the support plate 12 during movement, thus guaranteeing the accuracy and reliability of the machining process.

[0031] like Figure 4 As shown, a nozzle 15 is provided above the motor 11. One end of the nozzle 15 is connected to a water supply pipe 3, and the other end of the water supply pipe 3 is connected to the output end of the water pump 2. The input end of the water pump 2 is connected to the inside of the housing 1 through a pipe.

[0032] By using the nozzle 15 in conjunction with the water pump 2, the iron filings on the milling cutter 16 and the workpiece surface can be effectively and thoroughly removed.

[0033] like Figure 6 As shown, a filter plate 7 for filtering iron filings is slidably installed inside the housing 1.

[0034] The filter plate 7 inside housing 1 effectively filters iron filings. The filtered water is collected inside housing 1, allowing for water reuse. After use, the filter plate 7 can be easily removed for thorough cleaning. This prevents iron filings from clogging the holes in the filter plate 7, ensuring consistent filtration and normal operation of the equipment.

[0035] The above embodiments merely illustrate a portable high-precision rudder keyway machining device or several implementation methods of this utility model. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
