Description

Technical Field

[0001] This invention relates to the field of yacht technology, and more specifically to a method for creating a side thrust hole at the bow of a yacht. Background Technology

[0002] In the yacht manufacturing industry, the positioning of thrust tube openings has always been a technical challenge in hull machining. Traditional thrust tube openings are located on the lower forward section of the hull, where the opening surface is typically a hyperboloid with significant curvature. Traditional methods for positioning these openings mainly include template marking, but these methods have significant drawbacks in practical applications.

[0003] Template marking method: The outline of the hole is drawn on a template beforehand, then the template is manually attached to the location of the hole on the bow of the yacht, and finally the hole is made along the outline using a cutting device. The disadvantage of this operation is that the outline of the hole on the template is not easy to align when it is attached to the side wall of the yacht's bow. Even if the hole is made, due to the large positioning error, the side thrust tube often cannot be installed smoothly, requiring secondary adjustments, which increases manufacturing costs and labor time.

[0004] Based on the above, this invention proposes a method for side thrust opening at the bow of a yacht, which can effectively solve the above problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a method for side thrust hole opening at the bow of a yacht. This invention offers cost-effective equipment, can be operated directly in a workshop, has minimal opening error, and requires no secondary adjustments.

[0006] This invention provides a method for creating a side thrust hole at the bow of a yacht, comprising the following steps: S1. Perform horizontal calibration on the bottom of the scale plate on the side of the yacht's bow, the bottom of the tooling, and the bottom of the telescopic bracket of the laser level to ensure that the bottoms of the three are on the same reference plane. S2. Adjust the tooling so that the axis of the opening template on the tooling is on the same horizontal plane as the mark position of the tooling. S3. Mark the waterline on the outside of the hull to the corresponding scale position on the scale plate. Based on the opening design size parameters and the waterline scale value on the scale plate, calculate the opening scale value and mark it on the scale plate. S4. Adjust the telescopic bracket of the laser level so that the laser line emitted by the laser level is aligned with the marked opening position on the scale plate. S5. Adjust the tooling a second time to ensure that the axis of the marker and the opening template is on the same horizontal plane as the laser line; S6. Turn on the auxiliary light source. The light from the auxiliary light source is projected onto the opening template, so that the outline of the opening template is projected onto the side wall surface of the yacht bow, forming the opening outline line. S7. Based on the opening outline, a cutting device is used to precisely open a hole on the side wall of the yacht's bow.

[0007] In one embodiment, the yacht's bow is provided with first slide rails on both the left and right sides, and scale plates and tooling are slidably provided on both first slide rails. Each tooling is provided with an opening template. The front of the yacht's bow is provided with a second slide rail perpendicular to the yacht's axis, and the telescopic bracket of the laser level is slidably provided on the second slide rail. The first slide rails and the second slide rails are connected to each other to form a bottom positioning reference frame.

[0008] In one embodiment, a first slide rail is arranged side by side on one side of the bow of the yacht, and a scale plate and a tooling are slidably arranged on both first slide rails, with an opening template connecting the two toolings; a second slide rail is arranged perpendicular to the axis of the yacht at the front of the bow, and a telescopic bracket for a laser level is slidably arranged on the second slide rail; the first slide rail and the second slide rail are connected to each other to form a bottom positioning reference frame.

[0009] In one embodiment, the horizontal calibration in step S1 includes the following steps: S1.1: Rotate the support foot provided at the bottom of the first slide rail, the support foot is threadedly sleeved on the support rod, and the top of the support rod is fixedly connected to the first slide rail; S1.2: The axial position of the support leg along the support rod is adjusted by rotating the support leg, thereby changing the height of the corresponding end of the first slide rail; S1.3: Repeat the above operation to adjust the support leg of the other first slide rail until the two first slide rails are on the same horizontal plane; S1.4: Repeat steps S1.1 to S1.2 to adjust the support feet of the second slide rail until the second slide rail is on the same horizontal plane as the two first slide rails.

[0010] In one embodiment, both the first and second slide rails are provided with scale lines.

[0011] In one embodiment, the telescopic bracket of the laser level includes a first column, a first support column is slidably connected to the top of the first column, a first locking structure is provided between the first column and the first support column, and a mounting plate is provided on the top of the first support column, and the laser level is fixed to the mounting plate.

[0012] In one embodiment, the tooling includes a second column, a Y-shaped support is slidably connected to the top of the second column, a second locking structure is provided between the second column and the Y-shaped support, and a horizontal plate and a template fixing device are respectively provided at the two branch ends of the top of the Y-shaped support. The opening template is installed in the template fixing device, and the horizontal plate serves as the marker position and is kept at the same horizontal plane as the axis of the opening template.

[0013] In one embodiment, the perforation template is configured as an annular or cylindrical shape, and the diameter of the perforation template matches the diameter of the side push tube.

[0014] In one embodiment, the marker is located on the side of the opening template that is furthest from the yacht.

[0015] In one embodiment, the auxiliary light source is configured as a UV searchlight.

[0016] In one embodiment, The beneficial effects of the side thrust hole method for yacht bow provided in this embodiment of the invention are as follows: This invention provides a method for side-push hole opening at the bow of a yacht. Through the coordinated use of a laser level, scale plate, tooling and auxiliary light source, high-precision and high-efficiency hole positioning is achieved, effectively solving the technical problems of large positioning error and cumbersome operation of the traditional template scribing method.

[0017] This invention uses a laser level to calibrate the horizontal reference of the tooling and the hole-making template, and combines the waterline scale markings on the scale plate to ensure that the hole position strictly matches the design parameters. This avoids the positioning deviation caused by traditional manual scribing, significantly improves the hole-making accuracy, and reduces subsequent finishing processes.

[0018] This invention uses an auxiliary light source to project the outline of the opening template onto the hyperboloid surface of the hull, directly forming a clear opening outline line. This overcomes the problem of inaccurate fitting of traditional templates on curved surfaces and is especially suitable for areas with large curvature at the front of the hull.

[0019] This invention enables flexible movement and adjustment of the scale plate, tooling, and laser level through a sliding rail structure. Adjustable feet facilitate quick level calibration, addressing uneven workshop floors and allowing the entire device to be used directly in the workshop.

[0020] This invention can not only adapt to the opening requirements of side thrust tubes of different diameters, but also flexibly adjust the tooling arrangement (single-sided or double-sided arrangement) according to the hull structure, and has high versatility and adaptability.

[0029] The horizontal calibration in step S1 includes the following steps: S1.1: Rotate the support leg 12 provided at the bottom of the first slide rail 9. The support leg 12 is threadedly sleeved on the support rod 11, and the top of the support rod 11 is fixedly connected to the first slide rail 9.
