Problems solved by technology

[0005] The disadvantage of this operation is that the line-of-sight ruler and the spline are two tools. When drawing a line, workers need to manually align the spline, which has low precision and large errors; when drawing a curve with a large curvature, it is

Example Embodiment

Specific embodiment one

[0020] Such as figure 1 and figure 2 The scribing guide tool shown includes a spline 1, a weight 10, and a sight ruler 3. On the spline 1, a boss-shaped guide rail 11 is provided along the longitudinal direction of the spline. The tail end of the sight ruler 3 is fixedly installed on a square adapter block 12. The adapter block 12 is fixed with a connecting rod 4, and the sight ruler 3 and the connecting rod 4 are respectively fixed on two adjacent sides of the adapter block 12. And perpendicular to each other. The connecting rod 4 is perpendicular to the guide rail 11, and its bottom is provided with " ""-Shaped structure of the sliding block 41, the sliding block 41 and the guide rail 11 are slidingly matched, and the matching form is that the boss-shaped guide rail 11 extends between the two vertical sides of the sliding block 41, and the sliding block 41 and the guide rail 11 adopt a clearance fit A pair of balls 2 are provided on the inner wall o...

Example Embodiment

Specific embodiment two

[0023] The difference between the second embodiment and the first embodiment is that the guide rail 11 used is a grooved guide rail. image 3 As shown, the guide rail 11 is a narrow groove-shaped guide rail with a slot smaller than the width of the groove. The cross-sectional shape of the slider 41 matches the cross-sectional shape of the guide rail 11. The balls 2 are a pair, respectively located on the outer side wall of the slider 41 and the guide rail 11 between the inner wall.

Abstract

The invention discloses a curve-drawing guide tool. The curve-drawing guide tool comprises a spline, a mould weight and a sight ruler with a pencil container. When the spline is placed along a preset simulated curve, the mould weight is used for fixing the spline, a guide rail is arranged on the portion, in the longitudinal direction of the spline, of the spline, the tail end of the sight ruler is fixedly installed on a switching block, a connecting rod is fixed to the switching block, a sliding block is arranged at the bottom of the connecting rod and in sliding fit with the guide rail, the axis of the pencil container on the sight ruler is kept perpendicular to the guide rail, a slate pencil or other appropriate pencils are installed in the pencil container, the sight ruler is pushed to move, due to the limitation of the switching block, the connecting rod and the sliding block, the slate pencil can only move in the plane perpendicular to the guide rail, and lines drawn by the slate pencil are parallel to the guide rail, namely curves expressed by the spline. The curve-drawing guide tool is used for drawing curves in a moving mode, drawing is accurate, and efficiency can be effectively improved.

Description

technical field [0001] The invention relates to a tool used in the shipbuilding process, more specifically, to a marking guide tool for making a triangular template. Background technique [0002] The first process of shipbuilding is ship lofting. Ship lofting is to enlarge the hull line and components according to a certain proportion according to the design drawings. Through lofting, the smoother hull type value and the correct position, shape and size of the components on the hull can be obtained, which can provide construction basis for subsequent processes such as numbering, processing, assembly, etc. Make corrections or improvements where reasonable. According to the stakeout ratio, it can be divided into proportional stakeout and real scale stakeout; according to the stakeout method, it can be divided into computer stakeout and stakeout room stakeout. [0003] In the process of lofting in the lofting room, a curved surface template that can be combined at any time, t...
