Description

Technical Field

[0001] This utility model relates to the field of 3D printing, and in particular to an integrated 3D printing molding platform for complex flow channels of marine propulsion. Background Technology

[0002] Marine propulsion systems feature complex flow channel designs, posing numerous challenges to traditional manufacturing processes in producing such intricate structures. For instance, traditional methods rely on molds, resulting in long lead times, high costs, and difficulty in achieving high-precision manufacturing of complex flow channels. Furthermore, traditional design methods are heavily dependent on experience, limiting design effectiveness. In recent years, 3D printing technology, with its high precision, ability to manufacture complex structures, and rapid prototyping capabilities, has gradually become an effective means of addressing these issues.

[0003] Most existing 3D printing platforms are fixed, relying on the rotation of the print head to achieve complex construction needs. However, relying solely on the rotation of the print head means that the rotation range is affected by the printing material or the connecting arm, which can easily lead to printing dead zones and affect printing efficiency.

[0004] Therefore, it is necessary to propose an integrated 3D printing platform for complex flow channels in marine propulsion systems to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an integrated 3D printing platform for complex flow channels in marine propulsion systems. This addresses the problem that existing 3D printing platforms are mostly fixed and rely on the rotation of the print head to achieve complex construction needs. However, relying solely on the rotation of the print head means that the rotation range is affected by the printing material or connecting arms, which can easily lead to printing dead angles and affect printing efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an integrated 3D printing platform for complex flow channels in marine propulsion systems, comprising:

[0007] Base;

[0008] A first rotating shaft is rotatably connected to the top of the base;

[0009] A fixed plate is sleeved on the outside of the first rotating shaft. A driving mechanism is provided on the fixed plate, and a top plate is provided on the driving mechanism. The driving mechanism is used to drive the top plate to tilt.

[0010] A protective ring is provided at the outer edge of the top of the top plate;

[0011] The top plate has a cavity inside, an annular adsorption groove is provided at the top edge of the top plate, and an adsorption mechanism is provided at the bottom of the top plate.

[0012] The adsorption mechanism is connected to the cavity, and the interior of the cavity is connected to the annular adsorption tank.

[0013] Preferably, the adsorption mechanism includes a vacuum cleaner, which is fixed to the bottom of the top plate;

[0014] An air tube is installed between the vacuum cleaner and the interior of the cavity.

[0015] Preferably, a connecting seat is fixed to one side of the top of the base, a worm gear is rotatably connected inside the connecting seat, a worm wheel is sleeved on the outside of the first rotating shaft, and the worm gear and the worm wheel are connected by a transmission.

[0016] A first motor is provided on one side of the connecting seat, and the drive shaft of the first motor is connected to a worm gear.

[0017] Preferably, the drive mechanism includes a second motor, which is fixed inside the first rotating shaft. The drive shaft of the second motor extends out of the fixed disk, and a second bevel gear is sleeved on the outer side of the extended end of the drive shaft.

[0018] Preferably, a fixed base is fixed to the top of the fixed disk, and a second rotating shaft is rotatably connected inside the fixed base. A first bevel gear is sleeved on the outside of the second rotating shaft, and the first bevel gear and the second bevel gear are connected in a transmission manner.

[0019] Preferably, a connecting block is fixed to the middle of the outer side of the second rotating shaft, an electric push rod is fixed on the connecting block, and the bottom center of the top plate is fixed to the top of the electric push rod.

[0020] The technical effects and advantages of this utility model are as follows:

[0021] 1. After the second motor starts, the top plate can be tilted at an angle through the cooperation of the first and second bevel gears. Through the cooperation of the worm and worm wheel, the top plate can reach any angle, which is convenient for printing operations from different angles. When the 3D printing head is above the top plate, it can be rotated in conjunction with the rotation of the 3D printing head or by relying solely on the rotation of the top plate. This makes it easier to print the complex flow channels of marine propulsion, avoids complex flow channel angles, and has a wider range of applications.

[0022] 2. The adsorption mechanism is connected to the cavity, and the inside of the cavity is connected to the annular adsorption groove. If the printing material is large, it will cover the annular adsorption groove. The annular adsorption groove can also be used to adsorb and fix the printing material.

[0023] 3. A protective ring is provided on the outer edge of the top plate. The protective ring can protect the outer edge of the top plate. When printing, the generated debris and the debris that needs to be cut and glued after printing can be left inside the top plate. At this time, by tilting the top plate, the accumulated debris can slide down to the annular suction groove by gravity and the tilt angle, and be intercepted by the protective ring. By starting the vacuum cleaner, the accumulated debris can be collected, reducing the time and process of manual cleaning, making it simpler and more convenient. Attached Figure Description
