Abstract
The utility model relates to a simple compasses used for the fabrication and processing of air pipe fittings; the method is characterized in that: the movable supporting leg is inserted into a hole at the bottom of the sleeve, and the positioning supporting leg is arranged at the bottom of the other end of the round pipe; so, through the elasticity degree of tacking bolt, the control sleeve pipe slides on the pipe, after the interval distance between removal landing leg and the location landing leg is the radius of circle, the tacking bolt of screwing to use the location landing leg as the fulcrum, rotate the sleeve pipe and make the removal landing leg do the circle. The compasses ensure the accuracy of line drawing and positioning and improve the processing quality of air pipe fittings.
Description
Technical Field
The utility model relates to an air pipe preparation field specifically is a simple and easy compasses for tuber pipe fitting preparation processing.
Background
The traditional round or arc positioning and line drawing method for air pipe fittings (such as elbows, reducing pipes and air caps) comprises the following steps:
1. determining the position of a circle center on the plate, and determining the radius of a required circle or arc;
2. two nails are adopted, a thin rope is bound in the middle, and the length of the thin rope is equal to the radius of a circle or a circular arc to be drawn;
3. one end of the nail is fixed on the center of the circle properly, and the other end of the nail is pinched and tightened to tighten the string.
4. Rotating the nail clockwise or counterclockwise leaves a trace of a circle or arc on the board.
When the traditional positioning line drawing tool is used, the length of the rope needs to be adjusted and fed according to the required radiuses of different circles or arcs, so that the practicability and the cyclic usability are limited; in the process of drawing a circle or an arc by operating the nail, the precision is greatly reduced because the thin rope cannot be tightened or the nail cannot be ensured to be vertical, so that great difficulty is brought to the subsequent cutting work, and the processing quality of the pipe fitting is influenced; and the operation is more complicated and the labor cost is higher.
Disclosure of Invention
An object of the utility model is to overcome above-mentioned defect, provide a simple and easy compasses convenient to operation and system circle are accurate.
In order to achieve the above object, the present invention is realized as follows:
a simple compasses for manufacturing and processing an air pipe fitting comprises a circular pipe, a sleeve, a tacking bolt, a movable supporting leg and a positioning supporting leg, wherein the sleeve is sleeved at one end of the circular pipe, the top and the bottom of the sleeve are both provided with holes, an internal thread is arranged in the hole at the top of the sleeve, the tacking bolt penetrates through the air with the internal thread, the tacking bolt is rotated to enable the sleeve to be fastened with the circular pipe, the movable supporting leg is inserted into the hole at the bottom of the sleeve, and the positioning supporting leg is arranged at the bottom of the other end of the circular pipe; so, through the elasticity degree of tacking bolt, the control sleeve pipe slides on the pipe, after the interval distance between removal landing leg and the location landing leg is the radius of circle, the tacking bolt of screwing to use the location landing leg as the fulcrum, rotate the sleeve pipe and make the removal landing leg do the circle.
The bottom ends of the movable supporting leg and the positioning supporting leg are provided with spine parts; the pipe wall of the round pipe is provided with scales which take millimeters as a unit.
The simple compasses for manufacturing and processing the air pipe fittings are characterized in that the round pipe is made of an acrylic or galvanized steel pipe.
Compared with the traditional tool, the simple compasses ensure the accuracy of line drawing and positioning, improve the processing quality of the air pipe fitting and reduce the rework loss caused by unqualified processing quality; the device is not limited by the size of the air pipe fitting, and has strong practicability; the operation is simple, the labor cost is saved, and the working efficiency is improved. The method is particularly suitable for the pipe fitting manufacturing work with high pipe fitting processing requirement precision and large pipe fitting specification.
Drawings
FIG. 1 is a schematic structural view of the simple compasses.
Detailed Description
The invention is further illustrated by the following specific examples.
As shown in fig. 1, a simple compass for manufacturing and processing an air pipe fitting comprises a circular pipe 1, a sleeve 2, a tacking bolt 3, a movable leg 4 and a positioning leg 5, wherein the sleeve 2 is sleeved at one end of the circular pipe 1, holes are formed in the top and the bottom of the sleeve 2, an internal thread is arranged in the hole in the top of the sleeve 2, the tacking bolt 3 penetrates through the air with the internal thread, the sleeve 2 and the circular pipe 1 are fastened by rotating the tacking bolt 3, the movable leg 4 is inserted into the hole in the bottom of the sleeve 2, and the positioning leg 5 is arranged at the bottom of the other end of the circular pipe 1; so, through the elasticity degree of tacking bolt 3, control sleeve pipe 2 slides on pipe 1, after the interval distance between removal landing leg 4 and location landing leg 5 is the radius of circle, the tacking bolt 3 of screwing to use location landing leg 5 as the fulcrum, rotate sleeve pipe 2 and make removal landing leg 4 do the circle.
The bottom ends of the movable supporting leg and the positioning supporting leg are provided with spine parts; the pipe wall of the round pipe is provided with scales which take millimeters as a unit.
The simple compasses for manufacturing and processing the air pipe fittings are characterized in that the round pipe is made of an acrylic or galvanized steel pipe.
Compared with the traditional tool, the simple compasses ensure the accuracy of line drawing and positioning, improve the processing quality of the air pipe fitting and reduce the rework loss caused by unqualified processing quality; the device is not limited by the size of the air pipe fitting, and has strong practicability; the operation is simple, the labor cost is saved, and the working efficiency is improved. The method is particularly suitable for the pipe fitting manufacturing work with high pipe fitting processing requirement precision and large pipe fitting specification.
