Description
Technical Field
The utility model relates to the field of tools, in particular to a positioner for punching an arc-shaped end plate in a construction site.
Background
On a construction site, nozzles are often required to be added on end plates of containers to facilitate connection with external equipment, and the end plates are mostly arc-shaped structures or spherical surfaces, so that it is difficult to open holes at a certain position, especially holes with specific sizes, workers often draw lines according to hand feeling and then continuously correct the holes in the process of opening the holes, and the time is long.
Although the pipe through a nearly tangent plane with terminal surface arc structure can draw accurate line, different external cambered surfaces, different end plates, its arc tangent plane is often different, consequently can't be applicable to the complicated operating mode in building site.
In view of the problems in the prior art, the utility model designs and manufactures a positioner for the opening of the arc-shaped end plate of the construction site by combining years of design and use experience in the related field and assisting with over-strong professional knowledge, so as to overcome the defects.
SUMMERY OF THE UTILITY MODEL
For the problems in the prior art, the hole opening and scribing locator for the arc-shaped end plate of the construction site, provided by the utility model, can meet the hole opening and scribing requirements of arcs at any positions and in any sizes.
In order to achieve the purpose, the technical scheme adopted by the utility model is as follows: a positioner for opening of an arc-shaped end plate in a construction site comprises a vertical rod, wherein a threaded rod is arranged at the bottom of the vertical rod, a polished rod is arranged above the vertical rod, and the diameter of the polished rod is smaller than that of the vertical rod;
still include the horizon bar, be equipped with the unthreaded hole in the middle of the horizon bar, the horizon bar pass through the unthreaded hole with the polished rod cooperation makes the horizon bar can wind the polished rod rotates, be equipped with a plurality of mounting holes on the horizon bar, install the laser pen in the mounting hole.
Preferably, the plurality of mounting holes comprise four, and the distances from the four mounting holes to the light hole are respectively 25mm, 50mm, 75mm and 100 mm.
Preferably, the horizontal rod is a square rod, and the square rod is provided with a bubble level gauge.
The utility model discloses an useful part lies in:
1. according to the utility model, a threaded hole is drilled in the center position of the arc-shaped end plate needing to be drilled in advance, then the laser pen is fixed by matching the threaded rod at the bottom of the vertical rod with the threaded hole, aiming at the aperture needing to be drilled, the laser pen is installed in the corresponding installation hole, the horizontal rod rotates on the vertical rod to drive the laser pen to rotate, and then the laser pen is used for scribing by combining with the irradiation point of the laser pen, so that the scribing quality is ensured.
2. The distance of the mounting hole is set to meet the requirements of nozzles with different standards, and the corresponding common standard pipe diameters mainly comprise DN50, DN100, DN150 and DN 200.
3. The bubble level meter is arranged on the square rod, so that the influence of the deviation of the threaded hole on the arc-shaped end plate on the final scribing is avoided.

FIG. 1 is a schematic view of a site curved end plate opening locator;
FIG. 2 is a schematic view of a worksite curved end plate.
In the figure: 1-vertical rod, 2-horizontal rod, 3-laser pen, 4-arc end plate, 5-nozzle, 11-threaded rod, 12-polished rod and 21-mounting hole.
Detailed Description
In order to facilitate understanding for those skilled in the art, the present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1 and 2, the positioner for the hole opening of the arc-shaped end plate at the construction site comprises a vertical rod 1, a threaded rod 11 is arranged at the bottom of the vertical rod 1, a polished rod 12 is arranged above the vertical rod 1, and the diameter of the polished rod 12 is smaller than that of the vertical rod 1.
Still include the horizon bar 2, the horizon bar 2 is established to the square bar, is equipped with the unthreaded hole in the middle of the horizon bar 2, and the horizon bar 2 makes the horizon bar 2 can wind through unthreaded hole and polished rod 12 cooperation polished rod 12 rotates, is equipped with a plurality of mounting holes 21 on the horizon bar 2, installs laser pen 3 in the mounting hole 21, and a plurality of mounting holes 21 are preferred to be provided with four, and four mounting holes 21 are 25mm respectively apart from the distance of unthreaded hole, 50mm, 75mm, 100mm, its purpose is in order to satisfy different standard mouthpiece 5's needs, and the commonly used standard pipe diameter that corresponds mainly has DN50, DN100, DN150, DN 200.
The method comprises the following specific operation steps:
a threaded hole is drilled in the center position of the arc-shaped end plate 4 needing to be drilled in advance, then the laser pen 3 is installed in the corresponding installation hole 21 according to the aperture needing to be drilled, the horizontal rod 2 rotates on the vertical rod 1 to drive the laser pen 3 to rotate, and then the laser pen 3 is combined with the irradiation dot and dash line, so that the scribing quality is guaranteed.
In order to further improve the scribing accuracy, the bubble level meter is preferably arranged on the square rod, so that the influence of the inclined threaded hole on the arc-shaped end plate 4 on the final scribing is avoided.
It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should also be understood that various alterations, modifications and/or variations can be made to the present invention by those skilled in the art after reading the technical content of the present invention, and all such equivalents fall within the protective scope defined by the claims of the present application.
