Description

Round tube angle divider

Technical Field

The utility model relates to the field of production and manufacturing of measuring tools, in particular to a circular tube angle divider.

Background

In the installation process of the circular pipe for ship construction, ocean engineering construction and steel structure construction, a datum line needs to be determined so as to realize accurate butt joint of the circumferential surface of the circular pipe and other connecting pieces.

After the angle line is determined by dividing the angle on the circular tube, a straight line formed by connecting the angle lines at the two ends or the vertex of the angle is used as a datum line, so the datum line is a straight line arranged on the circumferential surface of the circular tube.

In the prior art, the angle of the round tube with low precision requirement is mainly measured through a tape measure or a ruler, and then the circumference is equally divided to realize the angle division. For the round tube minute angle with higher tolerance requirement, a theodolite is required to find out a cross equal minute point, and then a quarter of circular arc is equally divided; or the end face of the round pipe is firstly determined to be equally divided by using the level gauge, then the quarter circular arc is equally divided into angles, finally the angle dividing points on the two ends are connected to form a datum line, and if the datum line of other angles is needed, the eighth circular arc (even the sixteen circular arc) is also needed to be divided into angles. The method for dividing angles by using the theodolite and the level is more complex because of the need of dividing operations for a plurality of times, and a person with certain professional ability is required to accurately determine the corresponding datum line, so that the angle dividing efficiency is low.

The embodiment of the disclosure provides a circular tube chamfering device, which is used for chamfering circular tubes 10 with any diameter, determining a datum line on the circumferential surface of the circular tube 10 and realizing butt joint with other connecting pieces through the datum line.

Referring to fig. 1, the pipe corner device comprises a bracket 100, a disc 200 and a level 300, wherein the bracket 100 comprises a main body 110 and a support 120, the support 120 is arranged on one side of the main body 110, the support 120 is provided with an abutting joint 130 for abutting against the circumferential surface of the pipe 10 to be measured, the main body 110 is provided with a marking line 140, and the marking line 140 is arranged on the middle line of the main body 110; the disc 200 is provided with an angle scale 210, the disc 200 is rotatably provided to the main body 110, and the disc 200 is rotated so that the angle scale 210 can be aligned with the mark line 140; level 300 is provided on disc 200.

Referring to fig. 5 and 6, the principle of use of the circular tube protractor is as follows:

s100, when the round tube 10 is subjected to first angle division, rotating the disc 200 to enable the first angle scale 210 to be aligned with the mark line 140, keeping the disc 200 to be static on the main body 110 of the bracket 100, wherein the scale aligned with the mark line 140 is the angle of the required angle division;

s200, keeping the disc 200 stationary on the main body 110 of the bracket 100, placing a circular tube angle divider at one end of the circular tube 10, and vertically abutting the bracket 100 on the circumferential surface of the circular tube 10;

s300, moving the circular tube angle divider along the circumferential direction of the circular tube 10 until the level gauge 300 is horizontal, and marking the horizontal position of the level gauge 300 as a first point position;

s400, moving the circular tube angle divider along the axial direction of the circular tube 10 or abutting the circular tube angle divider against the other end of the circular tube 10, and using the same method, moving the circular tube angle divider along the circumferential surface of the circular tube 10 until the level gauge 300 is horizontal, determining a second point position and marking;

s500, connecting the first point location and the second point location to obtain a datum line.

In some embodiments, if the length of the tube 10 is too long, it is not convenient to draw a reference line after two points are obtained, and three or more points may be determined on the tube 10 using the same method.

The angle scale 210 ranges from 0 ° to 90 °, and the angle scale 210 includes 0 ° scribe lines and two 90 ° scribe lines, wherein the two 90 ° scribe lines are respectively located at two sides of the 0 ° scribe line, and the two 90 ° scribe lines are on the same straight line and parallel to the level 300. For convenience of explanation, the initial state of the pipe 10 resolver is defined as a 0 ° score line alignment mark line 140, and the 0 ° score lines are provided in the clockwise direction and the counterclockwise direction, and the 45 ° score lines and the 90 ° score lines are marked. When the disc 200 rotates anticlockwise and the mark line 140 is aligned with the corresponding score line for chamfering, the datum line obtained by chamfering is located above the 90-degree datum line; when the disc 200 rotates counterclockwise and the mark line 140 is angled with respect to the corresponding score line, the reference line from the angle is located below the 90 ° reference line.

It will be appreciated that the 90 ° reference line is the bisector of the tube 10 in the horizontal plane and that other angular reference lines are based on the 90 ° reference line. Generally, a substantially 90 ° reference line is determined by naked eyes before determining the reference line of other angles, or the 90 ° reference line is preferentially drawn.

For example, a reference line of 90 ° needs to be defined on the circumferential surface of a certain round tube 10. The length of the circular tube 10 is 3 meters, the standard line of the circular tube 10 with 3 meters is determined by only determining one point position at two ends of the circular tube 10, and the scale range of the circular tube 10 is 0-90 degrees.

For another example, it is also necessary to determine a 45 ° reference line on the upper half of the 3-meter round tube 10, and then the angle may be divided on the basis of the 0 ° reference line. Referring to fig. 7, the disc 200 is rotated counterclockwise to align the 45 ° graduation line with the marking line 140 on the main body 110, vertically support the bracket 100 against the circumference of the round tube 10, move the round tube resolver along the circumference of the round tube 10 until the level 300 is horizontal, mark the level 300 with the position being the third point, move the round tube resolver along the axial direction of the round tube 10 or abut the round tube resolver against the other end of the round tube 10, and move the round tube resolver along the circumference of the round tube 10 until the level 300 is horizontal, determine the fourth point and mark using the same method; and connecting the third point location and the fourth point location to obtain a 45-degree datum line.

In this embodiment, the reference lines of other angles can be obtained by the above method, and will not be described in detail.

In order to avoid that the scribed line is wiped off, a small hole (small eye) is marked on the scribed line at a certain distance, and the punch for marking is called a sample punch. Since the hole is punched with a punch (also called a "ocean punch"), this pilot hole is called a "sample punch". But after all, the manual operation is performed, and the accuracy degree is greatly related to the technology of operators. The holes are all positioned by an electronic ruler, and the holes can be accurately drilled at the positions to be drilled by directly using a center drill and a drill bit.
