When the anchor chain pipe is used, a first through hole is formed in the outer plate by taking the intersection point of the central axis of the anchor chain pipe and the outer plate as a circle center, a second through hole is formed in the deck, and the central axis of the anchor chain pipe passes through the second through hole in the deck; then, a steel wire is arranged along the first through hole and the second through hole in a penetrating mode, and the lower end of the steel wire is fixed at the intersection point of the central axis of the anchor chain pipe and the deck; laying the upper end of the steel wire in the main shaft pipe along the second notch, the first slot, the second slot and the first notch, straightening the steel wire to enable the central axis of the main shaft pipe and the central axis of the anchor chain pipe to be on the same straight line, fixing the second positioning seat on the outer plate, and fixing the first positioning seat on the ship body structure; finally, loosening the locking bolt, adjusting the position of the scribing mechanism on the cross rod according to the size of the outer diameter of the anchor chain pipe, and fastening the locking bolt when the distance between the scribing pen and the central axis of the main shaft pipe is equal to half of the outer diameter of the anchor chain pipe to position the scribing mechanism on the cross rod; and (5) marking the surface of the outer plate by using a marking pen by rotating the cross rod for a circle.

However, when the tool is used, the first positioning seat of the tool needs to be fixed on a hull structure, the second positioning seat needs to be fixed on an outer plate, the first slit and the second slit need to be aligned, and the steel wire rope can be installed in place; and still need weld and demolish after the marking off, the operation is comparatively loaded down with trivial details.

Disclosure of Invention

For solving the problem that current instrument exists, the utility model provides an appurtenance for trompil on curved plate, simple manufacture, convenient operation can also used repeatedly, and the precision is higher, the technical effect of the utility model is realized through following technical scheme:

an auxiliary tool for punching holes on a curved-surface outer plate structurally comprises a main shaft, a cross rod and a scribing mechanism, wherein the main shaft is made of square steel, a steel wire groove is formed in the main shaft in the length direction of the main shaft, one end of the cross rod is vertically fixed on the main shaft, the scribing mechanism is arranged on the cross rod, and the scribing mechanism is parallel to the main shaft. When in use, the steel wire groove of the tool is directly leaned against the straightened steel wire rope, so that the line can be drawn on the curved plate, and the tool is convenient and quick and has higher precision.

Further, the horizontal pole is fixed at the main shaft intermediate position, can guarantee the utility model discloses an instrument is rotating the in-process along wire rope comparatively steady.

Furthermore, the marking mechanism comprises a marking pen and a sliding shaft sleeve, the sliding shaft sleeve is arranged at the upper end of the marking pen, a fastening bolt is further arranged on the sliding shaft sleeve, and the sliding shaft sleeve is sleeved on the cross rod.

Furthermore, scales are arranged on the cross rod, and the scales start to be positioned at the bottom of the steel wire groove.

Furthermore, the width of the notch of the steel wire groove is 1-2mm, and the depth of the steel wire groove is more than 2 mm.

Further, the lower end of the marking pen is lower than the lower end of the main shaft.

Further, the steel wire groove is V type groove, and V type groove can guarantee the utility model discloses an instrument centre of a circle is confirmed when drawing a line.

The beneficial effects of the utility model reside in that, the utility model discloses an instrument is simple structure not only, and processing is easy, and during the use moreover, the radius of required trompil has directly been adjusted, leans on the V-arrangement groove of this instrument on wire rope, guarantees marking off pen lower extreme contact planking, and rotatory this instrument is marked off can, moreover can used repeatedly.
