Description

A measuring protractor for joinning longi to floor}

The present invention relates to a protractor for measuring the angle between the longage and the flat plate, in particular, when the assembly of the block and the plate when forming a block of the seam is formed at different positions when the joint angle of the joint surface having a different angle of one measuring device It relates to a protractor for measuring the joint angle between a long paper and a plate so that both can be measured.

In assembly of the ship block, many longines and plates are joined in such a way as welding or riveting. In addition, the joint angle between the long paper and the flat plate shall be measured and checked from time to time to ensure that it is bonded according to the intended design value.

1 is a side view showing an embodiment of a protractor for measuring the bonding angle between a long paper and a flat plate according to the prior art, and FIG. 2 is a perspective view showing an angle measurement using a protractor for measuring the joint angle between a long paper and a flat plate. Measuring protractor 1 is configured in the form of a right triangle and it can be seen that one side is formed with a handle (2) used for movement or use of the protractor.

Protractor of the type as shown in Figure 1 is used as follows.

First, one side of the protractor 1 is to be brought into close contact with the joint between the long paper and the iron plate. After the protractor 1 is fixed at the junction position between the longage 3 and the main plate 4, the baseline is marked on the longage 3 using another portion of the protractor 1, that is, an oblique portion of the protractor 1, or After that, measure the mounting angle of the Lonzy to be further bonded.

The protractor of the type described above had a disadvantage in that it was only able to measure or mark a given angle when the protractor was first manufactured. When manufacturing the hull block, the joint angle between the longage and the abacus varied, so it was necessary to manufacture a number of protractors corresponding to various angles. As the number of protractors increases, many problems have arisen in the management of the protractor, which leads to a problem in that the protractor cannot be found at a necessary time.

In addition, since the welding bead is formed at the joint portion of the long paper and the main plate, the protractor could not be brought into close contact with the long paper, and thus there was a problem that accurate angle measurement was impossible.

The present invention is to solve the above problems, in joining the long plate and the main plate in order to assemble the hull block can measure the angle of the joint portion that changes depending on the part of the hull block all one protractor It is an object of the present invention to provide a protractor for measuring the bonding angle between the long paper and the plate, which can prevent the protractor from being in close contact.

In order to achieve the above object, the present invention has a base in close contact with the junction of the rouge and the main plate, a main shaft which can move from side to side on the base and has a rotating shaft formed thereon, and a scale for measuring angle is formed around the rotating shaft. Consists of a rod that is connected by the axis of rotation, a scale for measuring angle is formed around the axis of rotation, and a linear marking part on the upper side, and a fixed rod that fixes the relative angles of the main and subchucks at the point where the main and sub-chucks indicate a certain angle. It is characterized by.

3 is a side view showing an embodiment of a protractor for measuring the curved portion of the long paper according to the present invention, the base 10 of the straight form in close contact with the junction of the long paper 3 and the main plate 4, the base 10 The main shaft 20, the main shaft 20 and the rotating shaft 15 which can move left and right on the rotation axis and a rotation axis 15 is formed thereon, and a first angle measurement scale 25 is formed around the rotation axis 15. Secondary chuck 40, the main chuck 20 and the secondary chuck 40 having a second angle measuring scale 30 formed around the rotary shaft 15 and a linear marking portion 35 formed on an upper side thereof. ) Is composed of a fixed rod 60 for fixing the relative angle of the main chuck 20 and the sub chuck 40 at a point indicating a certain angle.

Looking at the configuration of the subject innovation in detail as follows.

The base 10 is in close contact with the portion where the main plate 4 and the longage 3 are joined to form a straight line shape. The lower part of the contact surface of the base 10 is inclined obliquely at an angle in order to prevent the adhesion from being hindered by the beads formed at the portion where the main plate 4 and the longage 3 are joined.

The base 10 is provided with a main chuck 20 to enable the position movement in the longitudinal direction of the base 10. The main chuck 20 is formed to be movable on the base 10 in the longitudinal direction of the base 10, and the first angle for measuring the angle in units of 1 degree around the rotating shaft 15 formed on the top The scale 25 is formed.

The subchuck 40 is attached to the rotation shaft 15 of the main chuck 20 so as to rotate freely. A linear marking part 35 is attached to one side of the subchuck 40, and a second angle measurement scale 30 for measuring an angle in units of 0.5 degrees is formed around the rotation axis connecting portion of the subchuck 40. It is.

The first angle measurement scales 25 and the second angle measurement scales 30 formed on the main chuck 20 and the auxiliary chuck 40 are respectively the same as the scales formed on the vernier calipers. Allow measurement up to 20 degrees.

Both ends of the fixed rod 60 are fixed to the main chuck 20 and the chuck 40 so that the main chuck 20 and the chuck 40 rotate about the rotation axis 15 and indicate a predetermined angle. Each is attached to a predetermined position.

The present invention having the above configuration is to act as follows.

Rotating the auxiliary chuck 40 by an angle to be measured or an angle to be marked so that the marking portion 35 of the chuck 40 stays at a predetermined position, and is fixed using the fixing rod 60.

The protractor adjusted to the required angle is brought to the junction of the longage 3 and the main plate 4 to bring the base 10 into close contact with the junction. One side of the base 10 is inclined inward so as not to be disturbed by the welding bead, so that the protractor 100 is easily in close contact with the long side.

One end of the base 10 is positioned at a position to be measured, and then a marking reference line is displayed using the marking part 35 to facilitate subsequent joining operations.

In addition, in order to measure the angle of the portion where the long paper and the main plate is already bonded, the base 10 is brought into close contact with the joint portion, and then the chuck is rotated so that the marking unit can measure the angle.

The present invention configured as described above has the effect of measuring various angles using one protractor when measuring or marking the joint angles of various longines and plates when joining the longines and plates to assemble the hull block. It becomes possible.
